The United Nations declared 2016 as the International Year of Pulses (grain legumes) under the banner 'nutritious seeds for a sustainable future'. A second green revolution is required to ensure food and nutritional security in the face of global climate change. Grain legumes provide an unparalleled solution to this problem because of their inherent capacity for symbiotic atmospheric nitrogen fixation, which provides economically sustainable advantages for farming. In addition, a legume-rich diet has health benefits for humans and livestock alike. However, grain legumes form only a minor part of most current human diets, and legume crops are greatly under-used. Food security and soil fertility could be significantly improved by greater grain legume usage and increased improvement of a range of grain legumes. The current lack of coordinated focus on grain legumes has compromised human health, nutritional security and sustainable food production.

Training together: how another human's presence affects behavior during virtual human-based team training

Directory of Open Access Journals (Sweden)

Andrew Robb

2016-08-01

Full Text Available Despite research showing that team training can lead to strong improvements in team performance, logistical difficulties can prevent team training programs from being adopted on a large scale. A proposed solution to these difficulties is the use of virtual humans to replace missing teammates. Existing research evaluating the use of virtual humans for team training has been conducted in settings involving a single human trainee. However, in the real world multiple human trainees would most likely train together. In this paper, we explore how the presence of a second human trainee can alter behavior during a medical team training program. Ninety-two nurses and surgical technicians participated in a medical training exercise, where they worked with a virtual surgeon and virtual anesthesiologist to prepare a simulated patient for surgery. The agency of the nurse and the surgical technician were varied between three conditions: human nurses and surgical technicians working together; human nurses working with a virtual surgical technician; and human surgical technicians working with a virtual nurse. Variations in agency did not produce statistically significant differences in the training outcomes, but several notable differences were observed in other aspects of the team's behavior. Specifically, when working with a virtual nurse, human surgical technicians were more likely to assist with speaking up about patient safety issues that were outside of their normal responsibilities; human trainees spent less time searching for a missing item when working with a virtual partner, likely because the virtual partner was physically unable to move throughout the room and assist with the searching process; and more breaks in presence were observed when two human teammates were present. These results show that some behaviors may be influenced by the presence of multiple human trainees, though these behaviors may not impinge on core training goals. When

Migrating birds have been able to sustain an energy expenditure (EE) that is five times their basal metabolic rate. Although humans can readily reach these levels, it is not yet clear what levels can be sustained for several days. The study's purposes were 1) to determine the upper limits of human EE and whether or not those levels can be sustained without inducing catabolism of body tissues and 2) to determine whether initial body weight is related to the levels that can be sustained. We compiled data on documented EE as measured by doubly labeled water during high levels of physical activity (minimum of five consecutive days). We calculated the physical activity level (PAL) of each individual studied (PAL = total EE / basal metabolic rate) from the published data. Correlations were run to examine the relationship between initial body weight and body weight lost with both total EE and PAL. The uppermost limit of EE was a peak PAL of 6.94 that was sustained for 10 consecutive days of a 95-d race. Only two studies reported PALs above 5.0; however, significant decreases in body mass were found in each study (0.45-1.39 kg·wk(-1) of weight loss). To test whether initial weight affects the ability to sustain high PALs, we found a significant positive correlation between TEE and initial body weight (r = 0.46, P body weight (r = 0.27, not statistically significant). Some elite humans are able to sustain PALs above 5.0 for a minimum of 10 d. Although significant decreases in body weight occur at this level, catabolism of body tissue may be preventable in situations with proper energy intake. Further, initial body weight does not seem to affect the sustainability of PALs.

Reflections on human presence in space

Science.gov (United States)

Arnould, Jacques

2001-08-01

Humankind's exploration of Space has until now been understood as analagous to that of planet Earth: sending out crews to far-off, unknown lands in the hope of finding supplies of food, water or energy along with shelter and living-space. But Space is turning out to be much less hospitable than our earthly milieu in terms of resources as well as energy costs. It seems appropriate to ask what level of adaptation is needed for humans to travel and live in the cosmos, and to assess if the next logical step should necessarily be a programme of conquest analagous to that of the Moon — for example, towards Mars. Should we not rather be making more use of Earth's immediate neighbourhood, namely the sphere of a million of kilometres we call "Greater Earth"? In the same way, it is appropriate to ask questions about the conception of human beings which will from now on sustain the conquest of Space. The astronaut of the last forty years is the direct heir of the explorers of Ancient and Modern times; now, through the influence of science and technology, humanity has been put "into motion" not only geographically, but also in its most essential foundations: culture, psychology, philosophy. If the development of telepresence technology now gives us the ability to talk about a "Greater Human Being", it is chiefly through freedom of choice for oneself, for humanity and even for Earth.

When Should We Care About Sustainability? Applying Human Security as the Decisive Criterion

Directory of Open Access Journals (Sweden)

Alexander K. Lautensach

2012-05-01

Full Text Available It seems intuitively clear that not all human endeavours warrant equal concern over the extent of their sustainability. This raises the question about what criteria might best serve for their prioritisation. We refute, on empirical and theoretical grounds, the counterclaim that sustainability should be of no concern regardless of the circumstances. Human security can serve as a source of criteria that are both widely shared and can be assessed in a reasonably objective manner. Using established classifications, we explore how four forms of sustainability (environmental, economic, social, and cultural relate to the four pillars of human security (environmental, economic, sociopolitical, and health-related. Our findings, based on probable correlations, suggest that the criteria of human security allow for a reliable discrimination between relatively trivial incidences of unsustainable behavior and those that warrant widely shared serious concern. They also confirm that certain sources of human insecurity, such as poverty or violent conflict, tend to perpetuate unsustainable behavior, a useful consideration for the design of development initiatives. Considering that human security enjoys wide and increasing political support among the international community, it is to be hoped that by publicizing the close correlation between human security and sustainability greater attention will be paid to the latter and to its careful definition.

Early variability in the conceptualisation of "sustainable development and human factors".

Science.gov (United States)

Thatcher, Andrew

2012-01-01

The sub-discipline of "sustainable development and human factors" is relatively new, first being used in 2006 with a Technical Committee of the IEA being established only in 2009 and a similar special interest group on "green ergonomics" at the Institute of Ergonomics and Human Factors being established in 2010. In general though, the definitions and practice of "sustainable development" is highly contentious and ambiguous across a range of disciplines. This paper examines the diversity of definitions and approaches to sustainable development and human factors in the early papers in this sub-discipline. An examination of 45 chapters and papers (from 2008 to 2011) reveals a surprising consistency in the definitions used for sustainable development but also a large proportion of the papers where no definitions are given at all. The majority of papers were, however, biased towards an economic capital and social capital emphasis, which is to be expected of work traditionally in the ergonomics paradigm. Further, most papers were theoretical in nature demonstrating a great opportunity for empirical work. The variability in definitions is discussed in relation to the future challenges facing the growth of this emergent sub-discipline and opportunities for further theoretical and empirical work.

Biomimicry: a Necessary Eco-Ethical Dimension for a Future Human Sustainability

Directory of Open Access Journals (Sweden)

Javier Collado-Ruano

2015-07-01

Full Text Available This article reflects on the concept of “global citizenship” from a transdisciplinary methodology and a biomimetic approach. A sustainable human image appears with this epistemological symbiosis, that constitutes the DNA of a genuine tool of civilizational transformation. On the one hand, the transdisciplinary methodology is opened to the multi-referential conception of the three pillars proposed by Basarab Nicolescu (2008: levels of reality, logic of the included middle, and complexity. On the other hand, the concept of biomimicry approached by Janine M. Benyus (2012 identifies nine operating principles of life in order to mimic nature in the reformulation of new sustainable human production systems with the biosphere. The aim of this study is to identify international agreements on environmental and sustainable development, to elaborate some contribution in the post-2015 eco-political-educational strategic framework led by the United Nations with the Sustainable Development Goals. With the purpose of strengthening ties between education and sustainability through symbiotic bridges between nature and culture, the work identifies the vital axises that constitute the interdependence of ecosystems to make a biomimetic application in the social, political, and educational structures of human systems. Then, this paper is an innovational research that seeks to integrate the eco-ethics as a practice in the “Global Citizenship Education” proposed for UNESCO for next decade 2015-2025.

Reasserting the primacy of human needs to reclaim the 'lost half' of sustainable development.

Science.gov (United States)

Everard, Mark; Longhurst, James W S

2018-04-15

The concept of sustainable development evolved from growing awareness of the interdependence of social and economic progress with the limits of the supporting natural environment, becoming progressively integrated into global agreements and transposition into local regulatory and implementation frameworks. We argue that transposition of the concept into regulation and supporting tools reduced the focus to minimal environmental and social standards, perceived as imposing constraints rather than opportunities for innovation to meet human needs. The aspirational 'half' of the concept of sustainable development specifically addressing human needs was thus lost in transposing high ideals into regulatory instruments. The Sustainable Development Goals (SDGs) restore focus on interlinked human needs, stimulating innovation of products and processes to satisfy them. Through three case studies - PVC water pipes, river quality management in England, and UK local air quality management - we explore the current operationalisation of the concept in diverse settings, using the SDG framework to highlight the broader societal purposes central to sustainable development. Partnerships involving civil society support evolution of regulatory instruments and their implementation, optimising social and ecological benefits thereby serving more human needs. Restoring the visionary 'lost half' of sustainable development - meeting human needs in sustainable ways - creates incentives for innovation and partnership; an innovation framework rather than a perceived constraint.

Space Resource Utilization and Extending Human Presence Across the Solar System

Science.gov (United States)

Curreri, Peter A.

2005-01-01

The Presidents Vision for Exploration is not a single mission, but an open ended journey that seeks to answer "How can we live on other worlds?" Using space resources is the only known approach for affordable, sustained, flexible, and self sufficient, human occupation beyond Earth orbit. Earth is a large planet. A simple analysis using the rocket equation shows that if Earth were a bit larger, chemical propulsion as a mechanism to access space would become impractical. Thus, even with the most efficient chemical rocket launch capability, the cost of lifting massive payloads into space will remain very steep (currently about $l00k/lb to the Moon and greater than $500k/lb to Mars). Space resource utilization should begin with an aggressive broad based demonstration program as afforded by the precursor missions implementation of the President's Vision of Exploration. Ion engine upper stages, for example, were studied for over 30 years, but only implemented in design after the Deep Space 1 in space demonstration. These demonstrations should include: extraction of elements from lunar regolith, and Martian soil and atmosphere, demonstration of power break even and growth from lunar or Mars moons derived photovoltaics, oxygen extraction for life support and propellant, and metals and alloys for in space repair and the production of habits and radiation shielding. Space resource utilization yields operational dividends through the subsequent programs including: propellant from lunar oxygen which could cut transportation costs from Earth in half, mega watts per year of power grown from lunar photovoltaics at decreasing cost per kW, decreased cost for human Mars missions by a factor of 10 by using propellant derived from Mars atmosphere for return, and in space manufacturing and food production with space resources yielding safe sustained and eventually self sufficient human presence in space. After the demonstration and implementation, the space resource utilization

There is a growing consensus that within two decades initial human missions to Mars are affordable under plausible budget assumptions and with sustained international participation. In response to this idea, a distinguished group of experts from the Mars exploration stakeholder communities attended the "Affording Mars" workshop at George Washington University in December, 2013. Participants reviewed and discussed scenarios for affordable and sustainable human and robotic exploration of Mars, the role of the International Space Station over the coming decade as the essential early step toward humans to Mars, possible "bridge" missions in the 2020s, key capabilities required for affordable initial missions, international partnerships, and a usable definition of affordability and sustainability. We report here the findings, observations, and recommendations that were agreed to at that workshop.

Virtual reality exposure therapy (VRET) has been shown to be effective in treatment of anxiety disorders. Yet, there is lack of research on the extent to which interaction between the individual and virtual humans can be successfully implanted to increase levels of anxiety for therapeutic purposes. This proof-of-concept pilot study aimed at examining levels of the sense of presence and anxiety during exposure to virtual environments involving social interaction with virtual humans and using different virtual reality displays. A non-clinical sample of 38 participants was randomly assigned to either a head-mounted display (HMD) with motion tracker and sterescopic view condition or a one-screen projection-based virtual reality display condition. Participants in both conditions engaged in free speech dialogues with virtual humans controlled by research assistants. It was hypothesized that exposure to virtual social interactions will elicit moderate levels of sense of presence and anxiety in both groups. Further it was expected that participants in the HMD condition will report higher scores of sense of presence and anxiety than participants in the one-screen projection-based display condition. Results revealed that in both conditions virtual social interactions were associated with moderate levels of sense of presence and anxiety. Additionally, participants in the HMD condition reported significantly higher levels of presence than those in the one-screen projection-based display condition (p = .001). However, contrary to the expectations neither the average level of anxiety nor the highest level of anxiety during exposure to social virtual environments differed between the groups (p = .97 and p = .75, respectively). The findings suggest that virtual social interactions can be successfully applied in VRET to enhance sense of presence and anxiety. Furthermore, our results indicate that one-screen projection-based displays can successfully activate levels of anxiety in

ABSTRACT Human immunodeficiency virus type 1 (HIV-1) infection impairs liver function, and liver diseases have become a leading cause of morbidity in infected patients. The immunopathology of liver damage caused by HIV-1 remains unclear. We used chimeric mice dually reconstituted with a human immune system and hepatocytes to address the relevance of the model to pathobiology questions related to human hepatocyte survival in the presence of systemic infection. TK-NOG males were transplanted with mismatched human hematopoietic stem/progenitor cells and hepatocytes, human albumin concentration and the presence of human immune cells in blood were monitored for hepatocytes and immune reconstitution, and mice were infected with HIV-1. HIV-1-infected animals showed a decline in human albumin concentration with a significant reduction in percentage of human hepatocytes compared to uninfected mice. The decrease in human albumin levels correlated with a decline in CD4+ cells in the liver and with an increase in HIV-1 viral load. HIV-1 infection elicited proinflammatory response in the immunological milieu of the liver in HIV-infected mice compared to uninfected animals, as determined by upregulation of IL23, CXCL10 and multiple toll-like receptor expression. The inflammatory reaction associated with HIV-1 infection in vivo could contribute to the depletion and dysfunction of hepatocytes. The dual reconstituted TK-NOG mouse model is a feasible platform to investigate hepatocyte-related HIV-1 immunopathogenesis. This article has an associated First Person interview with the first author of the paper. PMID:29361613

Full Text Available The article places its contributions in a reflection of a pedagogical and social nature about the links that are established between social education, human rights and sustainability in community development. In this regard, in a historical and prospective key, it places emphasis on the need to promote educational actions that, being consistent with the principles of equity and justice, make it possible to build a more democratic, inclusive and cohesive local-global society.A future expectation that must be confined to educational theories and practices where local communities assume the role they play in their own development processes, with an alternative vision to the ways of educating people and themselves on a daily basis, respectful of human and ecological rights. A line of action that coincides with the commitments made at the Global Action Programme on Education for Sustainable Development, adopted by UNESCO, and Resolution A/70/1 adopted by the General Assembly in 2015, Transform our world: the 2030 Agenda for Sustainable Development, guaranteeing lifelong learning for all.In this objective beats a decisive, although not explicit, of a pedagogical-social vocation: to train citizens that, individually and collectively being aware of their role in socio-environmental changes, assume the responsibilities inherent to the values that sustain life in all its diversity. Social education and community development that, by projecting initiatives in different times and social spaces, allows formative opportunities to be expanded beyond the school system and its curricular practices.

Berylium (Be) is, together with As, Cd, Hg, Pb and Ti, one of the trace elements more toxic for human being (Vaessen) and Szteke, 2000; Yaman and Avci, 2006), but in spite of the exponential increment of its applications during the last decades, surprisingly there isn't hardly information about its presence and environmental distribution. The aim of this work is to evaluate the presence of Beryllium in urban soils in Alcala de Henares, (Madrid Spain).

Building the Leviathan--Voluntary centralisation of punishment power sustains cooperation in humans.

Science.gov (United States)

Gross, Jörg; Méder, Zsombor Z; Okamoto-Barth, Sanae; Riedl, Arno

2016-02-18

The prevalence of cooperation among humans is puzzling because cooperators can be exploited by free riders. Peer punishment has been suggested as a solution to this puzzle, but cumulating evidence questions its robustness in sustaining cooperation. Amongst others, punishment fails when it is not powerful enough, or when it elicits counter-punishment. Existing research, however, has ignored that the distribution of punishment power can be the result of social interactions. We introduce a novel experiment in which individuals can transfer punishment power to others. We find that while decentralised peer punishment fails to overcome free riding, the voluntary transfer of punishment power enables groups to sustain cooperation. This is achieved by non-punishing cooperators empowering those who are willing to punish in the interest of the group. Our results show how voluntary power centralisation can efficiently sustain cooperation, which could explain why hierarchical power structures are widespread among animals and humans.

The Social Origins of Sustained Attention in One-Year-Old Human Infants.

Science.gov (United States)

Yu, Chen; Smith, Linda B

2016-05-09

The ability to sustain attention is a major achievement in human development and is generally believed to be the developmental product of increasing self-regulatory and endogenous (i.e., internal, top-down, voluntary) control over one's attention and cognitive systems [1-5]. Because sustained attention in late infancy is predictive of future development, and because early deficits in sustained attention are markers for later diagnoses of attentional disorders [6], sustained attention is often viewed as a constitutional and individual property of the infant [6-9]. However, humans are social animals; developmental pathways for seemingly non-social competencies evolved within the social group and therefore may be dependent on social experience [10-13]. Here, we show that social context matters for the duration of sustained attention episodes in one-year-old infants during toy play. Using head-mounted eye tracking to record moment-by-moment gaze data from both parents and infants, we found that when the social partner (parent) visually attended to the object to which infant attention was directed, infants, after the parent's look, extended their duration of visual attention to the object. Looks to the same object by two social partners is a well-studied phenomenon known as joint attention, which has been shown to be critical to early learning and to the development of social skills [14, 15]. The present findings implicate joint attention in the development of the child's own sustained attention and thus challenge the current understanding of the origins of individual differences in sustained attention, providing a new and potentially malleable developmental pathway to the self-regulation of attention.

PDZ domain-binding motif of Tax sustains T-cell proliferation in HTLV-1-infected humanized mice

Science.gov (United States)

Artesi, Maria; Jalinot, Pierre

2018-01-01

Human T-cell leukemia virus type 1 (HTLV-1) is the etiological agent of adult T-cell leukemia/lymphoma (ATLL), an aggressive malignant proliferation of activated CD4+ T lymphocytes. The viral Tax oncoprotein is critically involved in both HTLV-1-replication and T-cell proliferation, a prerequisite to the development of ATLL. In this study, we investigated the in vivo contribution of the Tax PDZ domain-binding motif (PBM) to the lymphoproliferative process. To that aim, we examined T-cell proliferation in humanized mice (hu-mice) carrying a human hemato-lymphoid system infected with either a wild type (WT) or a Tax PBM-deleted (ΔPBM) provirus. We observed that the frequency of CD4+ activated T-cells in the peripheral blood and in the spleen was significantly higher in WT than in ΔPBM hu-mice. Likewise, human T-cells collected from WT hu-mice and cultivated in vitro in presence of interleukin-2 were proliferating at a higher level than those from ΔPBM animals. We next examined the association of Tax with the Scribble PDZ protein, a prominent regulator of T-cell polarity, in human T-cells analyzed either after ex vivo isolation or after in vitro culture. We confirmed the interaction of Tax with Scribble only in T-cells from the WT hu-mice. This association correlated with the presence of both proteins in aggregates at the leading edge of the cells and with the formation of long actin filopods. Finally, data from a comparative genome-wide transcriptomic analysis suggested that the PBM-PDZ association is implicated in the expression of genes regulating proliferation, apoptosis and cytoskeletal organization. Collectively, our findings suggest that the Tax PBM is an auxiliary motif that contributes to the sustained growth of HTLV-1 infected T-cells in vivo and in vitro and is essential to T-cell immortalization.

Full Text Available In recent years, sustainable development has been accounted as one of the mostimportant policy goals at the global level. Many empirical studies have beencarried out to determine the relationship between economic growth andenvironmental quality. The model so-called Environmental Kuznets Curve (EKCwas in most of empirical studies. The aim of this studyis to estimate a ModifiedEKC (MEKC in which development and sustain was usedinstead of economicgrowth and environment. In the present study, negative value of adjusted netsaving was used as non-sustainability indicator andhuman development indexwas used as development indicator. The statisticalpopulation is the Middle Eastcountries and the period of estimation is 1996-2010. The Panel Data method wasused in order to estimate the models in this groupof countries. Variables such asnatural resource abundant and institutional qualities such as Rule of Law, PoliticalStability, Regulatory Quality and Control of Corruption were used as controlvariable to specify the model. The results show aninverse N-shaped relationbetween human development and non-sustainability ofresources in the MiddleEast countries.

This study examined how creating a human presence in organizational online communication affects organization-public relationships and publics' favorable behavioral intentions to engage in word-of-mouth (WOM) and dialogic communications. Four hypotheses were tested in the context of Twitter through a 2×2 (presence: human vs. organizational×organization type: nonprofit vs. for-profit) within-subjects design. The results revealed that conversational human voice was perceived to be higher for Twitter pages of organizations with a human presence than for those with an organizational presence. Providing a human presence on social media through the use of social media managers' avatars and names appeared to promote favorable organization-public relationships and positive WOM communication. However, dialogic communication intentions did not significantly differ between organizations incorporating a human presence versus an organizational presence into their Twitter pages. The proposed dynamic role of human presence versus organizational presence adds a new perspective as to how organizations can take better advantage of interpersonal aspects of social media.

Murine models have suggested that CD8+ T-cell responses peak early in acute viral infections and are not sustained, but no evidence for humans has been available. To address this, we longitudinally analyzed the CD8+ T-cell response to human parvovirus B19 in acutely infected individuals. We...... observed striking CD8+ T-cell responses, which were sustained or even increased over many months after the resolution of acute disease, indicating that CD8+ T cells may play a prominent role in the control of parvovirus B19 and other acute viral infections of humans, including potentially those generated...

SUSTAINABLE DEVELOPMENT – HUMAN DEVELOPMENT CONNECTIONS IN THE POST-TRUTH ERA

Directory of Open Access Journals (Sweden)

ANDREEA CONSTANTINESCU

2017-08-01

Full Text Available Following the distancing of current policy from economic rigors and ethical demands aimed at redistribution of wealth, modern societies are parasitized by post-truth of actual facts. It distorts the shape and content of general interest data, for example political distortion of scientific evidence proving anthropogenic climate change. Under these circumstances, the question "to what extent economist’s truth stating what you cannot measure you cannot manage is sustained?" becomes absolutely legitimate. Regarding sustainable development management, monitoring the degree of achievement of Sustainable Development Goals is no longer sufficient to track progress in this area. Therefore, experts propose to introduce as much as possible qualitative data which, combined with quantitative data, will enhance their relevance and make them harder to be diverted for political purposes. This paper follows this direction, trying to prove that protection of data’s real meaning can be achieved by systemic analysis of all data originating from monitoring certain processes, which can be aggregated, with applicability in sustainable development. Thus, analyzing together data on sustainable development and those that indicates the state of human development emphasizes on one hand, the intrinsic link between these concepts and, on the other, maintain the sense of sustainability even in the post-truth era.

Building the Leviathan – Voluntary centralisation of punishment power sustains cooperation in humans

Science.gov (United States)

Gross, Jörg; Méder, Zsombor Z.; Okamoto-Barth, Sanae; Riedl, Arno

2016-01-01

The prevalence of cooperation among humans is puzzling because cooperators can be exploited by free riders. Peer punishment has been suggested as a solution to this puzzle, but cumulating evidence questions its robustness in sustaining cooperation. Amongst others, punishment fails when it is not powerful enough, or when it elicits counter-punishment. Existing research, however, has ignored that the distribution of punishment power can be the result of social interactions. We introduce a novel experiment in which individuals can transfer punishment power to others. We find that while decentralised peer punishment fails to overcome free riding, the voluntary transfer of punishment power enables groups to sustain cooperation. This is achieved by non-punishing cooperators empowering those who are willing to punish in the interest of the group. Our results show how voluntary power centralisation can efficiently sustain cooperation, which could explain why hierarchical power structures are widespread among animals and humans. PMID:26888519

CORPORATE SOCIAL RESPONSIBILITY IMPACTS ON SUSTAINABLE HUMAN DEVELOPMENT

Directory of Open Access Journals (Sweden)

Kerstin Anstätt

2016-06-01

Full Text Available The goal of this article is to critically analyze the findings of the first, recently published, studies about Corporate Social Responsibility (CSR impacts on Sustainable Human Development (SHD. We aim at deriving conclusions for effective CSR strategies and at identifying consequences for management and research. As CSR claims to create value for corporations and for society, we argue that the people-centered Capability Approach (CA is promising to provide neglected and much needed insights how corporate activities affect individuals and communities. Based on a survey of recent literature addressing CSR impacts on SHD, we highlight CSR potentials to improve average well-being in multiple dimensions of SHD. Moreover, we critically assess challenges and limitations of CSR as a strategy to preserve and foster SHD. For instance, studies have shown that, despite CSR-driven well-being increases, social capital, relational capabilities and collective agency may become challenged by corporate strategies. Moreover, corporate environmental impacts have been found to be less often addressed by both, companies and SHD researchers. Resulting inequality and fairness issues have been identified as causes of violence against corporations even in the presence of total well-being improvements. We conclude that companies should strategically take into account a comprehensive range of factors driving and hampering SHD to account for their whole portfolio of corporate opportunities and risks. This requires evaluating CSR impacts instead of only focusing on CSR inputs and outputs. Thereby, corporations can mitigate their risks, improve their stakeholder trust and strengthen their competitiveness.

Intergenerational Efforts to Develop a Healthy Environment for Everyone: Sustainability as a Human Rights Issue.

Science.gov (United States)

Kruger, Tina M; Savage, Caroline E; Newsham, Patrick

2014-12-01

As climate change proceeds at an unprecedented rate, concern for the natural environment has increased. The world's population aging also continues to rise at an unprecedented rate, giving greater attention to the implications of an older population. The two trends are linked through the fact that changes to the environment affect older adults, and older adults affect the environment. Sustainability is, therefore, an intergenerational phenomenon, and protecting resources today leaves a positive legacy and enhances quality of life for future generations. Older adults have much to share with younger generations about behaviors that promote sustainable living, yet few sustainability efforts are intergenerational in nature. As large numbers of people currently subsist without secure access to basic needs, ensuring equitable resource consumption for all generations is urgent and aligns with the Universal Declaration of Human Rights. Through exploring linkages between aging and sustainability, we identify intergenerational strategies to protect the environment and promote human rights and quality of life for older adults. © The Author(s) 2015.

Presence of adenovirus species C in infiltrating lymphocytes of human sarcoma.

Directory of Open Access Journals (Sweden)

Karin Kosulin

Full Text Available Human adenoviruses are known to persist in T-lymphocytes of tonsils, adenoids and intestinal tract. The oncogenic potential of different adenovirus types has been widely studied in rodents, in which adenovirus inoculation can induce multiple tumors such as undifferentiated sarcomas, adenocarcinomas and neuroectodermal tumors. However, the oncogenic potential of this virus has never been proven in human subjects. Using a highly sensitive broad-spectrum qRT-PCR, we have screened a set of different human sarcomas including leiomyosarcoma, liposarcoma and gastro intestinal stroma tumors. Primers binding the viral oncogene E1A and the capsid-coding gene Hexon were used to detect the presence of adenovirus DNA in tumor samples. We found that 18% of the tested leiomyosarcomas and 35% of the liposarcomas were positive for the presence of adenovirus DNA, being species C types the most frequently detected adenoviruses. However, only in one sample of the gastro intestinal stroma tumors the virus DNA could be detected. The occurrence of adenovirus in the tumor sections was confirmed by subsequent fluorescence in-situ-hybridization analysis and co-staining with the transcription factor Bcl11b gives evidence for the presence of the virus in infiltrating T-lymphocytes within the tumors. Together these data underline, for the first time, the persistence of adenovirus in T-lymphocytes infiltrated in muscular and fatty tissue tumor samples. If an impaired immune system leads to the viral persistence and reactivation of the virus is involved in additional diseases needs further investigation.

Integrating Sustainability Science with the Sciences of Human Well-being to Inform Design and Planning in an Urbanizing World

Alberti, M.; Graumlich, L. J.; Frumkin, H.; Friedman, D.

2012-12-01

A sustainable human future requires both healthy ecosystems and communities in which people thrive, with opportunities for health, well-being, happiness, economic prosperity, and equity. To make progress towards this goal, two largely disparate communities of scholars and practitioners must come together: sustainability science needs to be integrated with the sciences of human health and well-being. The opportunity for such integration is particularly ripe for urbanizing regions which not only dominate energy and resource use but also increasingly represent the human habitat. We present a conceptual framework that integrates sustainability science with the sciences of human health and well-being to explicitly articulate testable hypotheses on the relationships between humans and their habitat. We are interested in human behaviors and metrics of health and well-being in relationship to the characteristics of the built environment at various scales from buildings to metro regions. Focusing on the U.S. Pacific Northwest (PNW) as a testbed, we are building on our current empirical studies on urban sprawl and ecosystem function including biodiversity, air quality, hydrological, biogeochemical, and human health to develop formal hypotheses on how alternative urban design and development patterns may influence health outcomes and well-being. The PNW is an ideal setting for this work because of the connected metropolitan areas within a region characterized by a spectacular diversity of aquatic and terrestrial ecosystems and deeply held cultural and political aspirations towards sustainability. The framework also highlights opportunities for translation of knowledge to practice in the design and planning of built environments. For example, understanding these associations is critical to assessing tradeoffs in design and planning strategies and exploring potential synergies that optimize both sustainability and human well-being. In complex systems such as cities, managers

Biodiversity and human well-being: an essential link for sustainable development.

As society strives to transition towards more sustainable development pathways, it is important to properly conceptualize the link between biodiversity (i.e. genes, traits, species and other dimensions) and human well-being (HWB; i.e. health, wealth, security and other dimensions). Here, we explore how published conceptual frameworks consider the extent to which the biodiversity-HWB links are being integrated into public discourse and scientific research and the implications of our findings for sustainable development. We find that our understanding has gradually evolved from seeing the value of biodiversity as an external commodity that may influence HWB to biodiversity as fundamental to HWB. Analysis of the literature trends indicates increasing engagement with the terms biodiversity, HWB and sustainable development in the public, science and policy spheres, but largely as independent rather than linked terms. We suggest that a consensus framework for sustainable development should include biodiversity explicitly as a suite of internal variables that both influence and are influenced by HWB. Doing so will enhance clarity and help shape coherent research and policy priorities. We further suggest that the absence of this link in development can inadvertently lead to a ratcheting down of biodiversity by otherwise well-meaning policies. Such biotic impoverishment could lock HWB at minimum levels or lead to its decline and halt or reverse progress in achieving sustainable development. © 2016 The Authors.

Human-Nature for Climate Action: Nature-Based Solutions for Urban Sustainability

Directory of Open Access Journals (Sweden)

Helen Santiago Fink

2016-03-01

Full Text Available The global climate change agenda proceeds at an incremental pace while the Earth is approaching critical tipping points in its development trajectory. Climate action at this pinnacle juncture needs to be greatly accelerated and rooted in the fundamentals of the problem—human beings’ disconnection from nature. This paper underscores the valuable role nature and nature-based solutions can play in addressing climate change at the city scale and its implications for broader sustainability. Urban ecosystems (nature in cities are seen as an integral part of a proposed local climate action rubric wherein policy measures and integrated planning guide lowcarbon/impact development to create more resilient and sustainable urban environments. The use of green infrastructure is highlighted as a cost-effective means to contribute to mitigation and adaptation needs as well as to promote human wellbeing. The paper takes an exploratory view of the influence of ecosystem services, particularly cultural services, and its economics in relation to the individual and society to understand how biophilia can be nurtured to promote environmental stewardship and climate action.

Defining, Measuring, and Incentivizing Sustainable Land Use to Meet Human Needs

Land is a natural capital that supports the flow of an enormous amount of ecosystem services critical to human welfare. Sustainable land use, which we define as land use that meets both current and future human needs for ecosystem services, is essential to meet global goals for climate mitigation and sustainable development, while maintaining natural capital. However, it is not clear what governance is needed to achieve sustainable land use under multiple goals (as defined by the values of relevant decision-makers and land managers), particularly under climate change. Here we develop a conceptual model for examining the interactions and tradeoffs among multiple goals, as well as their spatial interactions (teleconnections), in research developed using Design Thinking principles. We have selected five metrics for provisioning (food production, and fiber production for wood and energy), regulating and maintenance (climate mitigation and biodiversity conservation), and cultural (heritage) ecosystem services. Using the case of Sweden, we estimate indicators for these metrics using a combination of existing data synthesis and process-based simulation modeling. We also develop and analyze new indicators (e.g., combining data on land use, bird conservation status, and habitat specificity to make a predictive model of bird diversity changes on agricultural or forested land). Our results highlight both expected tradeoffs (e.g., between food production and biodiversity conservation) as well as unexpected opportunities for synergies under different land management scenarios and strategies. Our model also provides a practical way to make decision-maker values explicit by comparing both quantity and preferences for bundles of ecosystem services under various scenarios. We hope our model will help in considering competing interests and shaping economic incentives and governance structures to meet national targets in support of global goals for sustainable management of land

The Sustainability Cycle and Loop: models for a more unified understanding of sustainability.

Hay, Laura; Duffy, Alex; Whitfield, R I

2014-01-15

In spite of the considerable research on sustainability, reports suggest that we are barely any closer to a more sustainable society. As such, there is an urgent need to improve the effectiveness of human efforts towards sustainability. A clearer and more unified understanding of sustainability among different people and sectors could help to facilitate this. This paper presents the results of an inductive literature investigation, aiming to develop models to explain the nature of sustainability in the Earth system, and how humans can effectively strive for it. The major contributions are two general and complementary models, that may be applied in any context to provide a common basis for understanding sustainability: the Sustainability Cycle (S-Cycle), and the Sustainability Loop (S-Loop). Literature spanning multiple sectors is examined from the perspective of three concepts, emerging as significant in relation to our aim. Systems are shown to provide the context for human action towards sustainability, and the nature of the Earth system and its sub-systems is explored. Activities are outlined as a fundamental target that humans need to sustain, since they produce the entities both needed and desired by society. The basic behaviour of activities operating in the Earth system is outlined. Finally, knowledge is positioned as the driver of human action towards sustainability, and the key components of knowledge involved are examined. The S-Cycle and S-Loop models are developed via a process of induction from the reviewed literature. The S-Cycle describes the operation of activities in a system from the perspective of sustainability. The sustainability of activities in a system depends upon the availability of resources, and the availability of resources depends upon the rate that activities consume and produce them. Humans may intervene in these dynamics via an iterative process of interpretation and action, described in the S-Loop model. The models are briefly

Pilar AZNAR MÍNGUET

2017-06-01

Full Text Available Sustainable Human Development (hereafter SHD is taking shape as a proposal for progress in the face of a crisis in civilization so complex and far-reaching that it is considered quite difficult to solve. The aim of this article is to offer a reasoned justification of the evolution of the concept of development and of the need for an educational commitment to be able to make progress towards it. Although it is still polemical and the object of criticism, SHD has become consolidated as a strongly ethical proposal to lead the change in the course of development, transversally affecting its multiple dimensions and advocating interdisciplinary and intercultural cooperation and dialogue. The article analyses the challenges posed by SHD to today’s global society, as well as some ways to respond to them from the field of educational action and research. It concludes with a reasoned structuring of the contents of the monograph and an analytical description of the contents of the different contributions.

Sustainable Wearables: Wearable Technology for Enhancing the Quality of Human Life

Directory of Open Access Journals (Sweden)

Jaewoon Lee

2016-05-01

Full Text Available This paper aims to elicit insights about sustainable wearables by investigating recent advancements in wearable technology and their applications. Wearable technology has advanced considerably from a technical perspective, but it has stagnated due to barriers without penetrating wider society despite early positive expectations. This situation is the motivation behind the focus on studies by many research groups in recent years into wearable applications that can provide the best value from a human-oriented perspective. The expectation is that a new means to resolve the issue can be found from a viewpoint of sustainability; this is the main point of this paper. This paper first focuses on the trend of wearable technology like bodily status monitoring, multi-wearable device control, and smart networking between wearable sensors. Second, the development intention of such technology is investigated. Finally, this paper discusses about the applications of current wearable technology from the sustainable perspective, rather than detailed description of the component technologies employed in wearables. In this paper, the definition of sustainable wearables is discussed in the context of improving the quality of individual life, social impact, and social public interest; those wearable applications include the areas of wellness, healthcare, assistance for the visually impaired, disaster relief, and public safety. In the future, wearables will not be simple data trackers or fun accessories but will gain extended objectives and meanings that play a valuable role for individuals and societies. Successful and sustainable wearables will lead to positive changes for both individuals and societies overall.

Full Text Available Abstract In this paper the authors analyze the impact of the composite human resource index on sustainable growth in a specific business sector in a transition country. Sustainability of country's economy is growingly relying on the knowledge economy which has been implemented in strategies of sustainable development throughout Europe. The knowledge economy is mostly based on human resources and the way they are organized and managed in the companies actively operating in competitive markets. In order to confirm importance of the human resources (HR index, results were tested by means of modeling, measuring and correlating the HR index with business results at micro level. The tests were conducted on the data from the survey in Serbian meat processing industry. The results were then compared with the results from the survey conducted in a financial industry. Moreover, a model was made that could be applicable in all countries that do not have available official statistic data on the level of investments in human resources. The focus was on determining the correlation direction, and hence creating a research model applicable in all business sectors. It has been found that a significant one-way correlation exists between business performance and increased HR index. In that way it has been confirmed that in Serbian economy that has recorded global decrease during transition, certain business sectors, and especially companies with high levels of investments in improving its HR index record above average and sustainable growth.

Is human society in denial regarding the tough questions about sustainability?

Directory of Open Access Journals (Sweden)

John Cairns, Jr.

2004-07-01

Full Text Available The news media report daily on unsustainable practices and events that impede progress toward sustainable use of the planet - production of greenhouse gases, biotic impoverishment, depletion of fossil waters (aquifers, human population growth, production of persistent toxic substances, loss of agricultural topsoil and land, rapid loss of old growth forests, and so on. Exponential economic growth both depletes natural capital more rapidly than it is regenerated and also gives an illusion of sustainable prosperity. Failure to act more expeditiously is almost certainly due to a number of factors; however, denial that a problem exists is, arguably, one of the most likely reasons. Just as an alcoholic or drug addict must first acknowledge that a problem exists before successful treatment is possible, so must those addicted to exponential growth on a finite planet.

Full Text Available Sustainability Science is an emerging, transdisciplinary academic field that aims to help build a sustainable global society by drawing on and integrating research from the humanities and the social, natural, medical and engineering sciences. Academic knowledge is combined with that from relevant actors from outside academia, such as policy-makers, businesses, social organizations and citizens. The field is focused on examining the interactions between human, environmental, and engineered systems to understand and contribute to solutions for complex challenges that threaten the future of humanity and the integrity of the life support systems of the planet, such as climate change, biodiversity loss, pollution, and land and water degradation. Since its inception in around the year 2000, and as expressed by a range of proponents in the field, sustainability science has become an established international platform for interdisciplinary research on complex social problems [1]. This has been done by exploring ways to promote ‘greater integration and cooperation in fulfilling the sustainability science mandate’ [2]. Sustainability science has thereby become an extremely diverse academic field, yet one with an explicit normative mission. After nearly two decades of sustainability research, it is important to reflect on a major question: what critical knowledge can we gain from sustainability science research on persistent socio-ecological problems and new sustainability challenges?

The article explains the use of the human capital sustainable development index (HCSDI) to assess the quality of the reproduction of human capital. The paper provides the algorithm for calculating HCSDI and its components. Authors estimated cross-country differences of HCSDI and developed econometric model of the impact of corruption on HCSDI. The use of this model has allowed to reveal the mechanism and assess the impact of corruption on HCSDI and its components. The results of econometric analysis revealed a negative multiplier effect: an increase in the corruption of the socio-economic system of the state by 1% caused HCSDI reduce by more than 1%. The results and conclusions may be proxy-assessments of the socio-economic consequences of violations of the stability of reproduction of human capital in the conditions of the growth of corruption in the country

According to Maslow's hierarchy of needs, the process of human development and utilization of water resources can be divided into three stages: engineering water conservancy, resource water conservancy and harmonious coexistence between man and water. These three stages reflect the transformation of the idea of human development and utilization of water resources and eventually reach the state of harmony between human being and water. At the same time, this article draws on the experiences of water management under the thinking of sustainable development in the United States, Western Europe, Northern Europe and Africa. Finally, this paper points out that we need to realize the harmonious coexistence between man and water and sustainable development of water resources in the process of development and utilization of water resources, which is the inevitable requirement of the economic and social development.

Human presence diminishes the importance of climate in driving fire activity across the United States

Science.gov (United States)

Syphard, Alexandra D.; Keeley, Jon E.; Pfaff, Anne Hopkins; Ferschweiler, Ken

2017-01-01

Growing human and ecological costs due to increasing wildfire are an urgent concern in policy and management, particularly given projections of worsening fire conditions under climate change. Thus, understanding the relationship between climatic variation and fire activity is a critically important scientific question. Different factors limit fire behavior in different places and times, but most fire-climate analyses are conducted across broad spatial extents that mask geographical variation. This could result in overly broad or inappropriate management and policy decisions that neglect to account for regionally specific or other important factors driving fire activity. We developed statistical models relating seasonal temperature and precipitation variables to historical annual fire activity for 37 different regions across the continental United States and asked whether and how fire-climate relationships vary geographically, and why climate is more important in some regions than in others. Climatic variation played a significant role in explaining annual fire activity in some regions, but the relative importance of seasonal temperature or precipitation, in addition to the overall importance of climate, varied substantially depending on geographical context. Human presence was the primary reason that climate explained less fire activity in some regions than in others. That is, where human presence was more prominent, climate was less important. This means that humans may not only influence fire regimes but their presence can actually override, or swamp out, the effect of climate. Thus, geographical context as well as human influence should be considered alongside climate in national wildfire policy and management.

Abusafieh, Shaden; Razem, Maiss

2017-11-01

Recently, technological advancements in the sustainable design field have allowed us to reduce the ecological impact of the built environment, to reduce consumption of non-renewable resources, to create healthy environments and in some cases may even rehabilitate the ecosystem. Nevertheless, several studies have been carried out showing that sustainable technology does not automatically lead to environmentally friendly behaviors in its users. Various environmental problems threaten environmental sustainability and many of these problems are rooted in human behavior. Unfortunately, there is a lack in studies which take into consideration the human behavior influences within a sustainable built environment. We believe that the built environment should be used to support human goals and requirements, but at the same time we should consider it as a context in which human values and behaviors are cultivated. This research aimed to help in promoting environmental sustainability by using architectural design in changing relevant human behavior toward an environmentally friendly behavior. In order to achieve this, the research adopted Environment-centered Approach to gain more acute perspective into the relationship between the physical environment and human behavior, focusing on social, psychological and physical influences of the built environment. It appears that environmental psychology's merits have high potential in changing behavior within the built environment. The research provides a systematic approach for selecting, assessing, evaluating the behaviors to be changed and the factors that determine them. Furthermore, this approach helps in choosing the best interventions that could be applied in built environment to encourage such a sustainable behavior. This study tried to construct an agenda for further researches to find particular architectural design elements and strategies that we can harness to develop a pro-environment human behavior.

Full Text Available Recently, much attention has been paid to sustainable development in cities. The quality of human life is directly related to environmental quality. Because many people live in cities as a place of social, economic and cultural relationships, certain issues such as environmental crises, energy, air and noise pollution and traffic jams are some of the factors that can alter the quality of human life. Therefore, in order to improve the quality of human life, attention to sustainable development (or sustainability in cities is proposed. Sustainable building has a comprehensive significance that begins with the conception of negative and positive impacts on the environment. Several descriptions of sustainable or green buildings have been created; however, they all pursue one goal, which is to create sustainable urban developments and protection of the environment. The quality of indoor environments, materials, and energy consumption, water usage, the impact of building construction processes and building maintenance are some of the factors that affect the environment and sustainability. Sustainable building is an attempt to relieve the minus impacts on the environment that occur during a building’s lifetime. This research investigates the important factors that have relevance to green buildings and introduces several criteria of sustainable housing.

Energy consumption, human well-being and economic development in central and eastern European nations: A cautionary tale of sustainability

International Nuclear Information System (INIS)

Jorgenson, Andrew K.; Alekseyko, Alina; Giedraitis, Vincentas

2014-01-01

Sustainability is fundamentally a challenge of tradeoffs. In order to improve human well-being through economic development we consume nonrenewable energy and other natural resources, relying on a broad range of ecosystem services. Enhancing sustainability requires reducing the “energy intensity of human well-being (EIWB)”: the amount of energy used per unit of human well-being. In this study we employ longitudinal analysis techniques to assess the temporally dynamic relationship between EIWB and economic development for a sample of 12 Central and Eastern European (CEE) nations for the 1992 to 2010 period. These are nations that have recently transitioned, which is still an ongoing process, from socialist command economies to market demand economies. During this ongoing transition, many of them have experienced declines in energy intensity, coupled with increased energy efficiency, while human well-being has improved considerably. The results of the analysis indicate that the relationship between EIWB and economic growth in CEE nations is complex and has changed dramatically through time. Of particular importance, the later years of the study exhibit an increasingly sustainable relationship between EIWB and economic development. The findings point to future possibilities for relatively more harmonious relationships between development, human well-being, and the natural environment. - Highlights: • We analyze the energy intensity of well-being in Central and Eastern European nations. • The effect of economic development is time-dynamic. • Other factors influence the energy intensity of well-being. • The results highlight possibilities for enhanced sustainability policies

Interaction Challenges in Human-Robot Space Exploration

Fong, Terrence; Nourbakhsh, Illah

2005-01-01

In January 2004, NASA established a new, long-term exploration program to fulfill the President's Vision for U.S. Space Exploration. The primary goal of this program is to establish a sustained human presence in space, beginning with robotic missions to the Moon in 2008, followed by extended human expeditions to the Moon as early as 2015. In addition, the program places significant emphasis on the development of joint human-robot systems. A key difference from previous exploration efforts is that future space exploration activities must be sustainable over the long-term. Experience with the space station has shown that cost pressures will keep astronaut teams small. Consequently, care must be taken to extend the effectiveness of these astronauts well beyond their individual human capacity. Thus, in order to reduce human workload, costs, and fatigue-driven error and risk, intelligent robots will have to be an integral part of mission design.

Concept of environment, sustainable development and respect for human rights

Urjana ÇURI

2013-12-01

Full Text Available The insistence on the definition of environmental protection is an aspiration which has served as prerequisites to the implementation of human rights in a global economic crises. European Regional System has traditionally been focused on the protection of civil and political rights. In the wake of environmental risks that imply the violation of human rights, the emphasis has been placed more on the social, economic and cultural. Collective mechanisms to appeal to the United Nations and the European Court of Human Rights, gave a number of decisions on matters implicating environmental laws and policies. What is to be noted, is the evolution of the guarantees provided under the European Convention on Human Rights, which refers to a substantial understanding of environmental protection, and also including procedural aspects related to the protection of the right to life, privacy, property, information and effective means of appeal. This evolution has been launched by the growing need for states to take preventive measures and policies to the requirements for a balanced sustainable economic development, avoiding environmental risks that imply the violation of human rights. Proportionality in the protection of the interests in this respect creates a context for a fair trial, but also promotes an open and constructive dialogue between judges and lawmakers to protect the public interest.

This paper gives an overview of the National Aeronautics and Space Administration (NASA) Office of Chief Technologist (OCT) led Space Technology Roadmap definition efforts. This paper will given an executive summary of the technology area 07 (TA07) Human Exploration Destination Systems (HEDS). These are draft roadmaps being reviewed and updated by the National Research Council. Deep-space human exploration missions will require many game changing technologies to enable safe missions, become more independent, and enable intelligent autonomous operations and take advantage of the local resources to become self-sufficient thereby meeting the goal of sustained human presence in space. Taking advantage of in-situ resources enhances and enables revolutionary robotic and human missions beyond the traditional mission architectures and launch vehicle capabilities. Mobility systems will include in-space flying, surface roving, and Extra-vehicular Activity/Extravehicular Robotics (EVA/EVR) mobility. These push missions will take advantage of sustainability and supportability technologies that will allow mission independence to conduct human mission operations either on or near the Earth, in deep space, in the vicinity of Mars, or on the Martian surface while opening up commercialization opportunities in low Earth orbit (LEO) for research, industrial development, academia, and entertainment space industries. The Human Exploration Destination Systems (HEDS) Technology Area (TA) 7 Team has been chartered by the Office of the Chief Technologist (OCT) to strategically roadmap technology investments that will enable sustained human exploration and support NASA s missions and goals for at least the next 25 years. HEDS technologies will enable a sustained human presence for exploring destinations such as remote sites on Earth and beyond including, but not limited to, LaGrange points, low Earth orbit (LEO), high Earth orbit (HEO), geosynchronous orbit (GEO), the Moon, near

Discontinuity of human presence at Atapuerca during the early Middle Pleistocene: a matter of ecological competition?

Increasing evidence suggests that the European human settlement is older than 1.2 Ma. However, there is a fierce debate about the continuity or discontinuity of the early human settlement of Europe. In particular, evidence of human presence in the interval 0.7-0.5 Ma is scarce in comparison with evidence for the previous and later periods. Here, we present a case study in which the environmental conditions at Sierra de Atapuerca in the early Middle Pleistocene, a period without evidence of human presence, are compared with the conditions in the previous period, for which a relatively intense human occupation is documented. With this objective in mind, the available resources for a human population and the intensity of competition between secondary consumers during the two periods are compared using a mathematical model. The Gran Dolina site TD8 level, dated to 0.7-0.6 Ma, is taken as representative of the period during which Atapuerca was apparently not occupied by humans. Conditions at TD8 are compared with those of the previous period, represented by the TD6-2 level, which has yielded abundant evidence of intense human occupation. The results show that survival opportunities for a hypothetical human population were lower at TD8 than they were at TD6-2. Increased resource competition between secondary consumers arises as a possible explanation for the absence of human occupation at Atapuerca in the early Middle Pleistocene.

In the economist's view, collective hunger goes beyond chronic hunger, involves a sudden outbreak of deprivation for a portion of the population. To eliminate hunger in the modern world, it is crucial to understand the cause of collective hunger in a broad way, and not just because of some mechanical imbalance between food and population. By illustrating the deprivation of liberty, child labor is included as one of the impediments to sustainable human development.

Sustaining evidence-based interventions (EBIs) is an ongoing challenge for dissemination and implementation science in public health and social services. Characterizing the relationship among human resource capacity within an agency and subsequent population outcomes is an important step to improving our understanding of how EBIs are sustained. Although human resource capacity and population outcomes are theoretically related, examining them over time within real-world experiments is difficult. Simulation approaches, especially agent-based models, offer advantages that complement existing methods. We used an agent-based model to examine the relationships among human resources, EBI delivery, and population outcomes by simulating provision of an EBI through a hypothetical agency and its staff. We used data from existing studies examining a widely implemented HIV prevention intervention to inform simulation design, calibration, and validity. Once we developed a baseline model, we used the model as a simulated laboratory by systematically varying three human resource variables: the number of staff positions, the staff turnover rate, and timing in training. We tracked the subsequent influence on EBI delivery and the level of population risk over time to describe the overall and dynamic relationships among these variables. Higher overall levels of human resource capacity at an agency (more positions) led to more extensive EBI delivery over time and lowered population risk earlier in time. In simulations representing the typical human resource investments, substantial influences on population risk were visible after approximately 2 years and peaked around 4 years. Human resources, especially staff positions, have an important impact on EBI sustainability and ultimately population health. A minimum level of human resources based on the context (e.g., size of the initial population and characteristics of the EBI) is likely needed for an EBI to have a meaningful impact on

Stimulation of THP-1 cells with phorbol myristate acetate (PMA) to prompt their differentiation into macrophage-like cells and evaluation of the possible induction of ER. The expression of ER was analyzed by immunocytochemical assay, reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot analysis. After stimulation by PMA, the human myeloid monocytic THP-1 cells showed the presence of ER, together with markers of monocytic cell differentiation such as CD68, CD54 and HLA-DR. Estrogen effects may be exerted directly through ER on monocytes/macrophages. PMA-treated THP-1 cells may constitute a useful in vitro model to determine the effects of estrogens on macrophage-like cells and their implications in the inflammatory and immune processes.

The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, and 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

Oceans and Human Health: Linking Ocean, Organism, and Human Health for Sustainable Management of Coastal Ecosystems

Sandifer, P. A.; Trtanj, J.; Collier, T. K.

2012-12-01

Scientists and policy-makers are increasingly recognizing that sustainable coastal communities depend on healthy and resilient economies, ecosystems, and people, and that the condition or "health" of the coastal ocean and humans are intimately and inextricably connected. A wealth of ecosystem services provided by ocean and coastal environments are crucial for human survival and well being. Nonetheless, the health of coastal communities, their economies, connected ecosystems and ecosystem services, and people are under increasing threats from health risks associated with environmental degradation, climate change, and unwise land use practices, all of which contribute to growing burdens of naturally-occurring and introduced pathogens, noxious algae, and chemical contaminants. The occurrence, frequency, intensity, geographic range, and number and kinds of ocean health threats are increasing, with concomitant health and economic effects and eroding public confidence in the safety and wholesomeness of coastal environments and resources. Concerns in the research and public health communities, many summarized in the seminal 1999 NRC Report, From Monsoons to Microbes and the 2004 final report of the US Commission on Ocean Policy, resulted in establishment of a new "meta-discipline" known as Oceans and Human Health (OHH). OHH brings together practitioners in oceanography, marine biology, ecology, biomedical science, medicine, economics and other social sciences, epidemiology, environmental management, and public health to focus on water- and food-borne causes of human and animal illnesses associated with ocean and coastal systems and on health benefits of seafood and other marine products. It integrates information across multiple disciplines to increase knowledge of ocean health risks and benefits and communicate such information to enhance public safety. Recognizing the need for a comprehensive approach to ocean health threats and benefits, Congress passed the Oceans and

International migration and sustainable human development in eastern and southern Africa.

Science.gov (United States)

Oucho, J O

1995-01-01

International migration in eastern and southern Africa (ESA) is rarely addressed in population and development policies or regional organizations, and regional organizations must in the articulation of sustainable shared development identify the role of international migration. Poor quality data on international migration hampers analysis. Sustainable, shared, and human development within the region are subregional issues. Permanent migration is characterized among ESA countries as increasing demographic ethnic pluralism that may result in redrawing of territorial boundaries and further population movement. Portuguese and Arab settlement and integration in eastern areas resulted in coexistence, while European immigration to South Africa resulted in racial segregation. Modern colonial settlement and the aftermath of political conflict resulted in independent countries after the 1960s and outmigration of nonAfrican groups. Much of the labor migration in ESA is unskilled workers moving to South African mining regions. Labor migration to Zimbabwe and Zambia declined after the 1960s. The formation of the Common Market for ESA and the potential merger with the Preferential Trade Area and South African Development Community is a key approach to integration of migration into regional cooperation and shared development. Refugee movements create the most problems. Prior to 1992 ESA countries accounted for 83.4% of refugees, particularly in Mozambique, Ethiopia, and Somalia. Some countries blame poor economic performance on the deluge of refugees. Illegal migration is currently detected because of the required work permits, but the adoption of the Common Market would obscure this phenomenon. Human development is affected most by migrations related to drought, labor migration to strong economic areas, and return migration. The Inter-Governmental Authority on Drought and Development needs to become more active and establish better policies on nomadic and refugee movements and

There are no large hydraulic structures in Qishan River cause the less human interference than other major river in Taiwan. However, the aquatic habitats still suffer disturbance from the discharge changes greatly between wet and drought season, and Jiaxian Weir and Yuemei Weir draw surplus water from Qishan River to Nanhua Reservoir and Agongdian Reservoir respectively. The weir operation rule doesn't clear define how much environmental flow should be preserved for maintaining downstream ecological environment. Hence, the study proposes a process for evaluating environmental flow under considering impact on human well-being and ecosystems sustainability. Empirical formula, hydrological, hydraulic and habitat methodologies were used to propose the environmental flow alternatives. Next, water allocation model and Habitat model were used to analysis the impact of environment flow alternatives on human well-being and ecosystems sustainability. The results show the suggested environmental flow in Qishan River is estimated by MAF10%. The environmental flow is between 8.03 10.83 cms during wet season and is between 1.07 1.44cms during wet season. The simulation results also provide the evidence from diverse aspect to help different authorities realized what they get and lose. The information can advance to reach a consensus during negotiations with different authorities and help decision maker make decisions.

Modelling of a plasma column sustained by a travelling circularly polarized electromagnetic wave (m=1 mode) in the presence of a constant axial magnetic field

A set of equations modelling a low-pressure plasma column sustained by a travelling electromagnetic wave in the dipolar mode in the presence of a constant external magnetic field is presented. It is shown that, from a practical point of view, only the m = 1 mode (the right-hand-polarized wave) can sustain plasma columns in a wide region of gas-discharge conditions: plasma radius R, wave frequency ω, magnetic field B 0 and low pressures, irrespective of the nature of the gas. The main result of this study is that the magnetic field makes it possible to sustain a plasma column for values of σ smaller than σ cr = 0.3726, below which, in the absence of a magnetic field, the dipolar wave cannot produce a plasma. Moreover, at a fixed wave power, the magnetic field - in contrast with the case of plasma columns sustained by azimuthally symmetric waves - increases the plasma density and its axial gradient. The limit of an infinite external magnetic field (Ω → ∞) is also considered. A three-dimensional wave structure is obtained, and it indicates that the wave can be a generalized surface mode, a pure surface or a pseudosurface one. (author)

Human behavior research and the design of sustainable transport systems

Schauer, James J.

2011-09-01

Transport currently represents approximately 19% of the global energy demand and accounts for about 23% of the global carbon dioxide emissions (IEA 2009). As the demand for mobility is expected to continue to increase in the coming decades, the stabilization of atmospheric carbon dioxide levels will require the evolution of transport, along with power generation, building design and manufacturing. The continued development of these sectors will need to include changes in energy sources, energy delivery, materials, infrastructure and human behavior. Pathways to reducing carbon from the transport sector have unique challenges and opportunities that are inherent to the human choices and behavioral patterns that mold the transportation systems and the associated energy needs. Technology, government investment, and regulatory policies have a significant impact on the formulation of transportation infrastructure; however, the role of human behavior and public acceptance on the efficiency and effectiveness of transport systems should not be underestimated. Although developed, rapidly developing, and underdeveloped nations face different challenges in the establishment of transport infrastructure that can meet transport needs while achieving sustainable carbon dioxide emissions, the constraints that establish the domain of possibilities are closely related for all nations. These constraints include capital investment, fuel supplies, power systems, and human behavior. Throughout the world, there are considerable efforts directed at advancing and optimizing the financing of sustainable infrastructures, the production of low carbon fuels, and the production of advanced power systems, but the foundational work on methods to understand human preferences and behavior within the context of transport and the valuation of reductions in carbon dioxide emissions is greatly lagging behind. These methods and the associated understanding of human behavior and the willingness to pay for

An inflatable lunar/Mars analog habitat (ILMAH), simulated closed system isolated by HEPA filtration, mimics International Space Station (ISS) conditions and future human habitation on other planets except for the exchange of air between outdoor and indoor environments. The ILMAH was primarily commissioned to measure physiological, psychological, and immunological characteristics of human inhabiting in isolation, but it was also available for other studies such as examining its microbiological aspects. Characterizing and understanding possible changes and succession of fungal species is of high importance since fungi are not only hazardous to inhabitants but also deteriorate the habitats. Observing the mycobiome changes in the presence of human will enable developing appropriate countermeasures with reference to crew health in a future closed habitat. Succession of fungi was characterized utilizing both traditional and state-of-the-art molecular techniques during the 30-day human occupation of the ILMAH. Surface samples were collected at various time points and locations to observe both the total and viable fungal populations of common environmental and opportunistic pathogenic species. To estimate the cultivable fungal population, potato dextrose agar plate counts method was utilized. The internal transcribed spacer region-based iTag Illumina sequencing was employed to measure the community structure and fluctuation of the mycobiome over time in various locations. Treatment of samples with propidium monoazide (PMA; a DNA intercalating dye for selective detection of viable microbial populations) had a significant effect on the microbial diversity compared to non-PMA-treated samples. Statistical analysis confirmed that viable fungal community structure changed (increase in diversity and decrease in fungal burden) over the occupation time. Samples collected at day 20 showed distinct fungal profiles from samples collected at any other time point (before or after

Sunardi, O.

2017-12-01

Medium-sized food manufacturing enterprises in Indonesia are significant in a number of contexts, in terms of their part to the national production (GDP) and their establishment to the employment. In term of their role to national production, manufacturing sector contributes the highest GDP by 85%. In this sector, food manufacturing subsector contributes the highest GDP. Nevertheless, they faced the same common problems: quality of human capital and sustainability issues. Previous government supplementary programs have been established to expand the human capital capability amongst medium enterprises. Adequate amount of fund has been apportioned to develop human capital, though, the medium enterprises sustainability is still in question. This study proposes and examines the human capital role from informal knowledge sharing perspective. By conducting qualitative approach through interviews to four informants in Indonesian medium-sized food manufacturing enterprises, a set of hypotheses is derived from this study for future quantitative study. This study indicates that human capital traits (diverse education background, employee skills, and employee experience) could leverage the practice of informal knowledge sharing. Constructs such as mutual trust and reciprocal intention could play as mediating variables, and cultural interpretation perspective could act as moderating factor to informal knowledge sharing effectiveness. In final, informal knowledge sharing is indicated to play as moderating variable for human capital policy and practice to support enterprise sustainability.

Astrobiological aspects of Mars and human presence: pros and cons.

Horneck, G

2008-08-01

After the realization of the International Space Station, human exploratory missions to Moon or Mars, i.e. beyond low Earth orbit, are widely considered as the next logical step of peaceful cooperation in space on a global scale. Besides the human desire to extend the window of habitability, human exploratory missions are driven by several aspects of science, technology, culture and economy. Mars is currently considered as a major target in the search for life beyond the Earth. Understanding the history of water on Mars appears to be one of the clues to the puzzle on the probability of life on Mars. On Earth microorganisms have flourished for more than 3.5 Ga and have developed strategies to cope with so-called extreme conditions (e.g., hot vents, permafrost, subsurface regions, rocks or salt crystals). Therefore, in search for life on Mars, microorganisms are the most likely candidates for a putative biota on Mars and the search for morphological or chemical signatures of life or its relics is one of the primary and most exciting goals of Mars exploration. The presence of humans on the surface of Mars will substantially increase this research potential, e.g., by supporting deep subsurface drilling and by allowing intellectual collection and sophisticated in situ analysis of samples of astrobiological interest. On the other hand, such long-duration missions beyond LEO will add a new dimension to human space flight, concerning the distance of travel, the radiation environment, the gravity levels, the duration of the mission, and the level of confinement and isolation the crew will be exposed to. This will raise the significance of several health issues, above all radiation protection, gravity related effects as well as psychological issues. Furthermore, the import of internal and external microorganisms inevitably accompanying any human mission to Mars, or brought purposely to Mars as part of a bioregenerative life support system needs careful consideration with

In the Americas, yellow fever virus transmission is a latent threat due to the proximity between urban and wild environments. Although yellow fever has nearly vanished from North and Central America, there are still 13 countries in the Americas considered endemic by the World Health Organization. Human cases usually occur as a result of the exposure to sylvatic yellow fever in tropical forested environments; but urban outbreaks reported during the last decade demonstrate that the risk in this environment still exists. The objective of this study was to identify spatial patterns and the relationship between key geographic and environmental factors with the distribution of yellow fever human cases in the Americas. An ecological study was carried out to analyze yellow fever human cases reported to the Pan American Health Organization from 2000 to 2014, aggregated by second administrative level subdivisions (counties). Presence of yellow fever by county was used as the outcome variable and eight geo-environmental factors were used as independent variables. Spatial analysis was performed to identify and examine natural settings per county. Subsequently, a multivariable logistic regression model was built. During the study period, 1,164 cases were reported in eight out of the 13 endemic countries. Nearly 83.8% of these cases were concentrated in three countries: Peru (37.4%), Brazil (28.1%) and Colombia (18.4%); and distributed in 57 states/provinces, specifically in 286 counties (3.4% of total counties). Yellow fever presence was significantly associated with altitude, rain, diversity of non-human primate hosts and temperature. A positive spatial autocorrelation revealed a clustered geographic pattern in 138/286 yellow fever positive counties (48.3%). A clustered geographic pattern of yellow fever was identified mostly along the Andes eastern foothills. This risk map could support health policies in endemic countries.

Ericsson, Maja; Skog, Oskar

The aims of this study were to investigate the presence of human herpesvirus 6 (HHV6) A and B in human pancreata and to search for signs of active infection in this organ of subjects with and without type 1 diabetes (T1D). Pancreata from brain-dead organ donors with and without T1D were examined for the presence of HHV6 genomic sequences by polymerase chain reaction (PCR), transcripts by reverse transcriptase-PCR, and protein by immunohistochemistry. Quantitative PCR of isolated pancreatic islets and exocrine cell clusters was used to determine the intrapancreatic location of HHV6 DNA. Human herpesvirus 6B genomic sequences were present in 1 of 2 donors who died of acute-onset T1D, 4 of 6 donors with long-standing T1D, and 9 of 12 nondiabetic donors. Higher copy numbers of HHV6B DNA were present in isolated islets than in exocrine tissue from the same donors. No signs of active HHV6 transcription were found. Human herpesvirus 6A was not present in any tested pancreas. The herein presented data demonstrate, for the first time, the presence of a latent HHV6B infection in the pancreas and islets of Langerhans. Whether this virus can contribute to disease in the pancreas remains to be determined.

The automobile and associated mobility system have had a major economic and ecological impact on human societies. The industrial revolution, during which the internal combustion engine has played a major role, has shaped secular, materialistic societies and associated consumption patterns that cannot be sustained in a future world of eight billion people. Creating a more sustainable world means maximizing human satisfaction while minimizing human impact on nature. Becoming more sustainable is best envisioned as a continuing process in which constraints and possibilities change over time and space. The sustainable process raises major controversies including how to define and measure progress, how to apportion wealth among generations, and between free trade and environmental preservation. Sustainable mobility implies major changes in approaches to transportation including stressing psychological rather than physical mobility, designing speciality vehicles for emerging niches, and placing special emphasis on mass transit systems for emerging megacities.

Is the presence of human papillomavirus (HPV) in semen associated with impairment of semen quality? In a large cohort of males seeking fertility evaluation, no associations were observed between seminal HPV presence and semen parameters. HPV is commonly detected in semen samples. Whether the presence of HPV is related to impairment of semen quality, remains unclear. This cross-sectional study included a cohort of 430 males. Male partners in couples seeking fertility evaluation provided one semen sample per person. Semen samples were tested for HPV-DNA using GP5+/6+-PCR. Sperm concentration was counted and motility was assessed in a Makler counting chamber at a magnification of ×200. The presence of antisperm antibodies was assessed by a mixed agglutination reaction (MAR)-test. Overall HPV was detected in 14.9% (64/430) of semen samples, including 2.1% (9/430) that contained both high-risk (hr) HPV and low-risk (lr) HPV types, 8.8% (38/430) with exclusively hrHPV types and 4.0% (17/430) with exclusively lrHPV types. The presence of HPV in semen was not associated with the age of the participants, seminal pH, semen volume, total sperm count, sperm concentration, progressive motility or the presence of antisperm antibodies. This study did not observe an association between HPV presence in semen and impairment of semen quality. However, we cannot exclude an effect of seminal HPV on early embryo development and clinical reproductive outcomes. As HPV is frequently present in semen, screening of donor semen for HPV should be considered to prevent iatrogenic cervical HPV infections in the recipient. However our findings do not support standardized HPV testing of semen in the diagnostic work-up of subfertile couples.

The ability of the earth to sustain health among humans and in the natural world is under threat from overpopulation, environmental degradation, and climate change. These global threats are anticipated to harm health and human occupation in many direct and indirect ways. Strategies are needed to mitigate the effects of these threats and to build individual and community capacities to foster resilience. This paper links issues of sustainability with occupational therapy philosophy and discusses how employing a sustainability lens with professional reasoning can help practitioners integrate sustainability into their practice. Human occupation is inseparable from the environments in which people live. Human occupation has caused the current environmental crisis, and targeted human action is required to safeguard future health and well-being. Occupational therapists have an ethical obligation to use professional reasoning strategies that, taken collectively, can help to build a sustainable and resilient future.

Full Text Available A bibliometric analysis was conducted to review social media research from different perspectives during the period of 2008–2014 based on the Science Citation Index and Social Science Citation Index database. Using a collection of 10,042 articles related to social media, the bibliometric analysis revealed some interesting patterns and trend of the scientific outputs, major journals, subject categories, spatial distribution, international collaboration, and temporal evolution in keywords usage in social media studies. The research on social media has been characterized by rapid growth and dynamic collaboration, with a rising number of publications and citation. Communication, Sociology, Public, Environment & Occupational Health, Business, and Multidisciplinary Psychology were the five most common categories. Computers in Human Behavior was the journal with the most social media publications, and Computers & Education ranked first according to the average citations. The two most productive countries were the U.S. and UK, delivering about half of the publications. The proportion of China’s internationally collaborative publications was the highest. The University of Wisconsin, the University of Michigan, and Harvard University were three most productive institutions. Several keywords, such as “Facebook”, “Twitter”, “communication”, “Social Networking Sites”, “China”, “climate change”, “big data” and “social support” increasingly gained the popularity during the study period, indicating the research trends on human behavior and sustainability.

Full Text Available Sustainable development is an objective for humanity of crucial importance to how we develop and evolve. It is also a rapidly growing discipline that is becoming increasingly applied in numerous areas, reflecting humanity's desire to ensure its activities can be sustained into the future and do not adversely affect the ecology or environment. Sustainable development is often defined based on the 1987 statement of the World Commission on Environment and Development (i.e., the Brundtland Commission. In that milestone document, sustainable development was defined as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." But new definitions are being developed as the discipline expands and becomes more multidisciplinary and complex.

From Environmental Connectedness to Sustainable Futures: Topophilia and Human Affiliation with Nature

Directory of Open Access Journals (Sweden)

Thomas Beery

2015-07-01

Full Text Available Human affiliation with nonhuman nature is an important dimension of environmental concern and support for pro-environmental attitudes. A significant theory of human connectedness with nature, the Biophilia Hypothesis, suggests that there exists a genetically based inclination for human affiliation with the biological world. Both support and challenge to the Biophilia Hypothesis are abundant in the literature of environmental psychology. One response that both challenges and builds upon the Biophilia Hypothesis is the Topophilia Hypothesis. The Topophilia Hypothesis has extended the ideas of biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. While the Topophilia Hypothesis is a new idea, it is built upon long-standing scholarship from humanistic geography and theories in human evolution. The Topophilia Hypothesis expands previous theory and provides a multidisciplinary consideration of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. Support for this possible co-evolutionary foundation for place-based human affiliation with nonhuman nature is explored from multiple vantage points. We raise the question of whether this affiliation may have implications for multifunctional landscape management. Ultimately, we propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable efforts at the local level with implications for the global.

2016-08-01

Full Text Available The hospitality industry is facing major challenges, among them the new competition from novel forms of supply in the sharing economy. Airbnb, Homeaway, and Niumba, among other websites offering accommodations, are having an important impact in the sector, changing existing conditions and the market for the traditional hospitality industry. In this context, a strategy based in differentiation can help to prevent drops in revenues and profitability. The main objective of this paper is analyse if commitment towards sustainability has a positive impact on financial performance and can be considered a positive strategy in this new environment. The empirical data refer to a sample of hotels in Barcelona, one of the most important tourist cities in Europe. Our results suggest that there is no clear relationship between sustainability and better financial performance; however, sustainability commitment is associated with a minimum size, which can also have positive effects in terms of economies of scale and finally affect profitability. Hotels more committed to environmental issues are located in areas with a lower density of Airbnb apartments, and this geographical distribution can be more positive than a situation of massive tourist concentration in specific areas with negative externalities for neighbours.

Ayyagari, R.R.; Khan-Dawood, F.S.

1987-01-01

Epidermal growth factor receptors are present in many reproductive tissues but have not been demonstrated in the human corpus luteum. To determine the presence of epidermal growth factor receptors and its binding characteristics, we carried out studies on the plasma cell membrane fraction of seven human corpora lutea (days 16 to 25) of the menstrual cycle. Specific epidermal growth factor receptors were present in human corpus luteum. Insulin, nerve growth factor, and human chorionic gonadotropin did not competitively displace epidermal growth factor binding. The optimal conditions for corpus luteum-epidermal growth factor receptor binding were found to be incubation for 2 hours at 4 degrees C with 500 micrograms plasma membrane protein and 140 femtomol 125 I-epidermal growth factor per incubate. The number (mean +/- SEM) of epidermal growth factor binding sites was 12.34 +/- 2.99 X 10(-19) mol/micrograms protein; the dissociation constant was 2.26 +/- 0.56 X 10(-9) mol/L; the association constant was 0.59 +/- 0.12 X 10(9) L/mol. In two regressing corpora lutea obtained on days 2 and 3 of the menstrual cycle, there was no detectable specific epidermal growth factor receptor binding activity. Similarly no epidermal growth factor receptor binding activity could be detected in ovarian stromal tissue. Our findings demonstrate that specific receptors for epidermal growth factor are present in the human corpus luteum. The physiologic significance of epidermal growth factor receptors in human corpus luteum is unknown, but epidermal growth factor may be involved in intragonadal regulation of luteal function

Lange-Morales, Karen; Thatcher, Andrew; García-Acosta, Gabriel

2014-01-01

In this paper, we analyse two approaches that attempt to address how a human factors and ergonomics (HFE) perspective can contribute to the sustainability of the human race. We outline the principles, purposes and fields of application of ergoecology and green ergonomics, and thereafter deal with their context of emergence, and the overlaps in purpose, and principles. Shared values are deduced and related to socio-technical principles for systems' design. Social responsibility and environmental/ecospheric responsibility are the leading threads of ergoecology and green ergonomics, giving rise to the values of: respect for human rights, respect for the Earth, respect for ethical decision-making, appreciation of complexity, respect for transparency and openness, and respect for diversity. We discuss the consequences of considering these values in HFE theory and practice.

2015-12-01

In an age when the escalating impact of human activity on the global environment has begun to threaten the long-term survival of humanity, increasing focus is being brought to bear on the scientific, social, economic, political, and cultural ramifications of the various courses of action open to individuals and societies across the globe. The intentional and intelligent modification of human behavior to balance environmental impact with human wellbeing is seen as the key to entering what Jeffrey Sachs has called the 'Age of Sustainable Development'. There are mechanisms, legal, socio-cultural, religious, economic, and technological that may ameliorate to varying degrees the environmental impact of human activity. These mechanisms are explored at length in the literature and assessed by their capacity to encourage or compel compliant behavior. They rely heavily on individual and collective choices based on rational self-interest, which is in turn informed by knowledge. The role of education in facilitating sustainable human activity is a key feature of many contributions to the literature. The alarming shortcoming in these discussions is the absence of an effective approach to learned sustainability that may achieve the necessary changes in human behavior and particularly adult choices with respect to daily acts of consumption. Sustainable practices and choices are most effectively produced through immersion in experientially based learning programs aimed at elementary and secondary school students. The experience of sustainable living during the critical phase of personal identity formation is the key to shaping behavior, and not just imparting knowledge. This AGU education session, ED041: Teaching Sustainability and Human Impact through Collaborative Teaching Methods, explores the principles on which such experiential immersion learning contributes to genuine sustainable behaviors and choices through targeted, intelligently designed residential programs.

Technological innovation, human capital and social change for sustainability. Lessons learnt from the industrial technologies theme of the EU's Research Framework Programme.

Europe is facing a twofold challenge. It must maintain or even increase its competitiveness, a basic requirement in a globalised economy and under the current demographic threat. It needs also to tackle the so-called "grand challenges", especially environmental issues, through a sustainable model of production and consumption. Such challenges should lead to new business and industrial models, based on more sustainable production and consumption chains, from design to end of life. This implies a need for new industrial materials and processes, new skills and, indeed, new values and life-styles. Sustainability and innovation are key elements of EU's Research and Innovation Framework Programmes, particularly in the field of industrial technologies (nanotechnologies, materials and industrial technologies), which objective is to "improve the competitiveness of the European industry and generate knowledge to ensure its transformation from a resource intensive to a knowledge intensive industry". Sustainability and innovation are interrelated challenges for R&D. Research can develop technical solutions to tackle environmental or societal challenges, but such technologies need to be successfully commercialised to have a real environmental impact. Several socio-economic studies carried-out by the European Commission show not only the emerging technological and industrial trends, but they also emphasise the need for linking sustainable technologies with social change. Human capital and new social behaviours are critical factors to combine economic competitiveness and sustainability: technology alone is no longer able to solve global challenges. But what kind of human capital (skills, behaviours, and values) are we referring to? How to encourage the shift towards a greener society through human capital? Which reforms are needed in education systems to move towards a sustainable economy? Are there examples of social innovation to be extrapolated and/or generalised? © 2013

Full Text Available The recent discourse on sustainability science calls for interdisciplinary research. The home economics science approach ranges from individual actions to the involvement of communities and societies at large, and thus it can provide important perspectives on cultural sustainability. The aim of the research is to study the linkage between cultural sustainability and service sector education to support the creation of sustainable professions. In the present small-scale empirical study, the food service degree curriculum of a Finnish vocational college and teachers’ group interview data were analyzed to find how cultural sustainability is presented in the curriculum and how it is understood by teachers and integrated into teaching practices. Previous cultural sustainability research identifies four perspectives of cultural sustainability: (1 vitality of cultural traditions; (2 economic starting point; (3 diversity together with maintenance of local culture; and (4 possible influence on the balance between human actions and environment. Findings indicate that sustainability, including cultural sustainability, is integrated in the curriculum and considered important by teachers. Translating these into practice remains a challenge. The balance between human and nature was mostly understood as recycling, use of public transport, sustainable consumption, and taking trips to the nature nearby. Cultural sustainability as a concept is not well known, although themes such as multicultural issues, equality, charity, and environmental responsibility were included in teachers’ practical lessons daily. Feasts and celebrations in learning were opportunities to view cultural sustainability widely. This paper provides a way forward for the teachers to develop further their pedagogical practices.

Sustainability and Risk Disclosure: An Exploratory Study on Sustainability Reports

Full Text Available Recent policy changes in sustainability reporting, such as the ones related to the new European Directive on non-financial disclosure (2014/95/EU, the standards issued by the American Sustainability Accounting Standard Board (SASB, the G4 guidelines issued by the Global Sustainability Standard Board (GSSB, and the framework of the International Integrated Reporting Council (IIRC stress the importance of extending the disclosure of ethical, social, and environmental risks within financial and social-environmental reporting. Institutional pressure has notably increased among organizations, in setting up risk management tools to understand sustainability risks within managerial and reporting practices. Given such institutional pressure, the corporate reaction in providing additional sustainability risk disclosure calls for attention and scrutiny. Therefore, this study aims at addressing such issues from an exploratory perspective. We based our analysis on a sample of large Italian organizations that issued sustainability disclosure in accordance with the Global Reporting Initiative (GRI, G4 guidelines, and we tested the relationship between their level of risk disclosure and other relevant variables. Consistently with the literature, we found that “experienced” sustainable reporters provide a significant volume of disclosure, and that disclosure quality on risk is positively influenced by their international presence and reporting experience. However, when accounting for specific risk-related areas of disclosure, only a few of them seem to adopt a managerial perspective linking strategy, risk metrics, and disclosure.

The purpose of this paper is to discuss conceptual requirements for a City Sustainability Index (CSI) and to review existing major sustainability indices/indicators in terms of the requirements. The following indices are reviewed: Ecological Footprint (EF), Environmental Sustainability Index (ESI), Dashboard of Sustainability (DS), Welfare Index, Genuine Progress Indicator (GPI), Index of Sustainable Economic Welfare, City Development Index, emergy/exergy, Human Development Index (HDI), Environmental Vulnerability Index (EVI), Environmental Policy Index (EPI), Living Planet Index (LPI), Environmentally-adjusted Domestic Product (EDP), Genuine Saving (GS), and some applications of composite indices or/and multivariate indicators to local or regional context as case studies. The key conceptual requirements for an adequate CSI are: (i) to consider environmental, economic and social aspects (the triple bottom line of sustainability) from the viewpoint of strong sustainability; (ii) to capture external impacts (leakage effects) of city on other areas beyond the city boundaries particularly in terms of environmental aspects; (iii) to create indices/indicators originally for the purpose of assessing city sustainability; and (iv) to be able to assess world cities in both developed and developing countries using common axes of evaluation. Based on the review, we conclude that it is necessary to create a new CSI that enables us to assess and compare cities' sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution. In the future, the CSI will be able to provide local authorities with guidance toward sustainable paths. - Highlights: Black-Right-Pointing-Pointer We derive the four key requirements for a new City Sustainability Index (CSI) system.

Sustainability and sacred values

Directory of Open Access Journals (Sweden)

John Cairns Jr.

2002-09-01

Full Text Available Successful implementation of the quest for sustainable use of the planet requires that human society both reexamine and expand present views of what is sacred and what is not. The most important aspect will be going beyond a homocentric focus to a biocentric emphasis. A unifying theme would be the desire to leave a habitable planet for human descendants and those of other species. It is unlikely that society can be confident of achieving sustainability until persuasive evidence supporting this belief has existed for several generations. In order for sustainable use of the planet to persist indefinitely, the conditions essential to this state must be morally preserved on sacred grounds. Viewing natural systems as sacred requires not only preventing damage to them but, wherever possible, repairing damage to them caused by humankind.

The practical organization of a responsible and sustainable business, the results of which are ever new products and services, which creates new jobs, and contributes, by aggregating systematically, to assessing new macroeconomic results, from GDP or NDP to import and export, and especially to sustainable economic development, requires the presence of both the three classical factors, i.e., capital, labour and location (land, and the other three essential new factors, which are called technology, information and the specific skills of the business owner, or simply of the entrepreneur.

of labour intensive processes and a systematic underestimation of environmental impacts has implications for decision-making. A brief review of the evaluation of human labour in ESAs reveals that only Emergy Assessment (EmA) accounts for labour as standard. Focussing on EmA, we find, however......Human labour is central to the functioning of any human-influenced process. Nevertheless, Environmental Sustainability Assessments (ESAs) do not systematically include human labour as an input. Systematic omission of labour inputs in ESAs may constitute an unfortunate, significant bias in favour......, that there is no agreement on the calculation method for labour. We formalise the calculation of human labour unit emergy values (UEVs) as being the ratio between the emergy resource basis of the labour system and a proxy for labour, with or without allocation to account for different qualities of labour.

Winning the sustainable development debate

Ritch, John; Cornish, Emma

Full text: This year - in Johannesburg from 26 August to 4 September - the world will witness what is expected to be the largest environmental gathering yet: the World Summit on Sustainable Development. Some 60,000 participants, including Heads of State, government officials, intergovernmental organizations, and environmental, business and scientific lobbies, will debate the world's progress in implementing 'Agenda 2 V - the sustainable development principles agreed in Rio de Janeiro in 1992. Some kind of deal, perhaps in the form of a declaration, will emerge from Johannesburg, reasserting international commitment to sustainable development. At this stage the content cannot be predicted. Experience warns us to expect a strong and virulent anti-nuclear lobby, not only as part of the 'environmental community', but within some of the governments themselves. Their role will be to achieve a text declaring nuclear an unsustainable energy source. The nuclear industry has six months to make its case, in the preparatory fora and elsewhere, that nuclear energy must be recognized - and at a minimum, not excluded - as a sustainable development technology. Twin goals of sustainable development: meeting human need and achieving environmental security. The principle of sustainable development aims at the long-term environmental protection of the planet - sparing our children and their children from living on a planet irredeemably spoilt through human action. An equally pressing issue is that of bridging the wealth gap between the North and South. In this vein, UN Secretary General Kofi Annan recently published his priorities for attention at the World Summit. These include: - Poverty eradication and achieving sustainable livelihoods; - Promoting health through sustainable development; - Access to energy and energy efficiency; - Managing the world's freshwater resources; - Sustainable development initiatives for Africa.

Sustainable rural learning ecologies- a prolegomenon traversing transcendence of discursive notions of sustainability, social justice, development and food sovereignty

Dipane Hlalele

2013-12-01

Full Text Available This paper contributes, through traversing contested notions of sustainability, social justice, development and food sovereignty, to discourses around creation of sustainable rural learning ecologies. There has always been at least in the realm of scientific discourse, an attempt to dissociate the natural or physical environment from the social and human environment. This trend did not only affect the two spheres of existence only. It is further imbued and spawned fragmented and pervasive terminology, practices and human thought. Drawing from the ‘creating sustainable rural learning ecologies’ research project that commenced in 2011, I challenge and contest the use of such discourses and argue for the transcendence of such. This would, in my opinion, create space for harmonious and fluid co-existence between nature and humanity, such that the contribution of learning practices exudes and expedites sustainability in rural ecologies.

Humanized HLA-DR4.RagKO.IL2RγcKO.NOD (DRAG) mice sustain the complex vertebrate life cycle of Plasmodium falciparum malaria.

Malaria is a deadly infectious disease affecting millions of people in tropical and sub-tropical countries. Among the five species of Plasmodium parasites that infect humans, Plasmodium falciparum accounts for the highest morbidity and mortality associated with malaria. Since humans are the only natural hosts for P. falciparum, the lack of convenient animal models has hindered the understanding of disease pathogenesis and prompted the need of testing anti-malarial drugs and vaccines directly in human trials. Humanized mice hosting human cells represent new pre-clinical models for infectious diseases that affect only humans. In this study, the ability of human-immune-system humanized HLA-DR4.RagKO.IL2RγcKO.NOD (DRAG) mice to sustain infection with P. falciparum was explored. Four week-old DRAG mice were infused with HLA-matched human haematopoietic stem cells (HSC) and examined for reconstitution of human liver cells and erythrocytes. Upon challenge with infectious P. falciparum sporozoites (NF54 strain) humanized DRAG mice were examined for liver stage infection, blood stage infection, and transmission to Anopheles stephensi mosquitoes. Humanized DRAG mice reconstituted human hepatocytes, Kupffer cells, liver endothelial cells, and erythrocytes. Upon intravenous challenge with P. falciparum sporozoites, DRAG mice sustained liver to blood stage infection (average 3-5 parasites/microlitre blood) and allowed transmission to An. stephensi mosquitoes. Infected DRAG mice elicited antibody and cellular responses to the blood stage parasites and self-cured the infection by day 45 post-challenge. DRAG mice represent the first human-immune-system humanized mouse model that sustains the complex vertebrate life cycle of P. falciparum without the need of exogenous injection of human hepatocytes/erythrocytes or P. falciparum parasite adaptation. The ability of DRAG mice to elicit specific human immune responses to P. falciparum parasites may help deciphering immune correlates

Ethiopia remains underdeveloped due to limitations in natural, human, social and built capital. A 2006 scientific atelier conducted in the city of Awassa, Ethiopia investigated investments in human and natural capital as a sustainable development strategy. Local stakeholders identified firewood shortages, degradation of croplands, rising lake levels encroaching on croplands and poor water quality as major impediments to development. They further identified ecological degradation as a key component of these problems, and they acknowledged multiple vicious cycles compounding the environmental and economic threats to the Awassa community. Proposed solutions included investment in natural capital in the form of reforestation activities, investment in human capital in the form of promoting more efficient wood stoves along with increasing public awareness of environmental threats, and investments in social capital in the form of inter-institutional coordination to address environmental problems. All recommended investments rely primarily on national resources, in distinct contrast to the extensive imports required for most built capital investments. Unfortunately, Awassa lacks the surplus necessary for major capital investments of any kind. The atelier therefore helped local participants identify potential funders and write grant proposals for various projects, though none have been funded so far. Reversing the ecological degradation on the scale necessary for sustained economic development in Ethiopia however will require a steady flow of substantial investments, and cannot rely solely on the short term generosity of funders. International payments for carbon sequestration and other ecosystem services could help provide the necessary resources. (author)

Urban microbiomes and urban ecology: how do microbes in the built environment affect human sustainability in cities?

Science.gov (United States)

King, Gary M

2014-09-01

Humans increasingly occupy cities. Globally, about 50% of the total human population lives in urban environments, and in spite of some trends for deurbanization, the transition from rural to urban life is expected to accelerate in the future, especially in developing nations and regions. The Republic of Korea, for example, has witnessed a dramatic rise in its urban population, which now accounts for nearly 90% of all residents; the increase from about 29% in 1955 has been attributed to multiple factors, but has clearly been driven by extraordinary growth in the gross domestic product accompanying industrialization. While industrialization and urbanization have unarguably led to major improvements in quality of life indices in Korea and elsewhere, numerous serious problems have also been acknowledged, including concerns about resource availability, water quality, amplification of global warming and new threats to health. Questions about sustainability have therefore led Koreans and others to consider deurbanization as a management policy. Whether this offers any realistic prospects for a sustainable future remains to be seen. In the interim, it has become increasingly clear that built environments are no less complex than natural environments, and that they depend on a variety of internal and external connections involving microbes and the processes for which microbes are responsible. I provide here a definition of the urban microbiome, and through examples indicate its centrality to human function and wellbeing in urban systems. I also identify important knowledge gaps and unanswered questions about urban microbiomes that must be addressed to develop a robust, predictive and general understanding of urban biology and ecology that can be used to inform policy-making for sustainable systems.

Sustainable design is a collective process whereby the built environment achieves unprecedented levels of ecological balance through new and retrofit construction, with the goal of long-term viability and humanization of architecture. Focusing on the environmental context, sustainable design merges the natural, minimum resource conditioning solutions of the past (daylight, solar heat, and natural ventilation) with the innovative technologies of the present.  The desired result is an integrated “intelligent” system that supports individual control with expert negotiation for resource consciousness. International experts in the field address the fundamental questions of sustainable design and landscape management: How should the sustainability of landscapes and buildings be evaluated? Which targets have to be set and which thresholds should not be exceeded? What forms of planning and governance structures exist and to what extent do they further the goals of sustainability?  Gathering 30 peer-reviewed ent...

Full Text Available The etiology and the molecular mechanisms related to breast carcinogenesis remain poorly understood. Some recent reports have examined the role of Human Papillomavirus (HPV in this disease. The purpose of this study was to determine the prevalence of HPV in breast cancer.Sixty one fresh frozen breast cancers samples were analyzed. Samples were tested for HPV by PCR, and products were automatically sequenced. Findings were correlated with clinical and pathological characteristics.The HPV DNA prevalence in the breast cancer samples was 26% (16/61. Clinical parameters were not statistically associated with HPV presence (p>0.05 χ(2 test. Sequence analysis in a subgroup of cases indicates the prevalence of low risk HPV11, followed by high risk HPV16. We found no HPV transcriptional activity.The present study demonstrated for the first time in Argentina the presence of HPV in a proportion of the malignant breast tissues. This finding suggests that HPV may have a biological significance in breast carcinogenesis.

Sustainable Fashion Supply Chain: Lessons from H&M

Full Text Available Sustainability is significantly important for fashion business due to consumers’ increasing awareness of environment. When a fashion company aims to promote sustainability, the main linkage is to develop a sustainable supply chain. This paper contributes to current knowledge of sustainable supply chain in the textile and clothing industry. We first depict the structure of sustainable fashion supply chain including eco-material preparation, sustainable manufacturing, green distribution, green retailing, and ethical consumers based on the extant literature. We study the case of the Swedish fast fashion company, H&M, which has constructed its sustainable supply chain in developing eco-materials, providing safety training, monitoring sustainable manufacturing, reducing carbon emission in distribution, and promoting eco-fashion. Moreover, based on the secondary data and analysis, we learn the lessons of H&M’s sustainable fashion supply chain from the country perspective: (1 the H&M’s sourcing managers may be more likely to select suppliers in the countries with lower degrees of human wellbeing; (2 the H&M’s supply chain manager may set a higher level of inventory in a country with a higher human wellbeing; and (3 the H&M CEO may consider the degrees of human wellbeing and economic wellbeing, instead of environmental wellbeing when launching the online shopping channel in a specific country.

Utilization of human amniotic mesenchymal cells as feeder layers to sustain propagation of human embryonic stem cells in the undifferentiated state.

Human embryonic stem (ES) cells are usually maintained in the undifferentiated state by culturing on feeder cells layers of mouse embryonic fibroblasts (MEFs). However, MEFs are not suitable to support human ES cells used for clinical purpose because of risk of zoonosis from animal cells. Therefore, human tissue-based feeder layers need to be developed for human ES cells for clinical purpose. Hereof we report that human amniotic mesenchymal cells (hAMCs) could act as feeder cells for human ES cells, because they are easily obtained and relatively exempt from ethical problem. Like MEFs, hAMCs could act as feeder cells for human ES cells to grow well on. The self-renewal rate of human ES cells cultured on hAMCs feeders was higher than that on MEFs and human amniotic epithelial cells determined by measurement of colonial diameters and growth curve as well as cell cycle analysis. Both immunofluorescence staining and immunoblotting showed that human ES cells cultured on hAMCs expressed stem cell markers such as Oct-3/4, Sox2, and NANOG. Verified by embryoid body formation in vitro and teratoma formation in vivo, we found out that after 20 passages of culture, human ES cells grown on hAMCs feeders could still retain the potency of differentiating into three germ layers. Taken together, our data suggested hAMCs may be safe feeder cells to sustain the propagation of human ES cells in undifferentiated state for future therapeutic use.

ICT Innovations for Sustainability is an investigation of how information and communication technology can contribute to sustainable development. It presents clear definitions of sustainability, suggesting conceptual frameworks for the positive and negative effects of ICT on sustainable development. It reviews methods of assessing the direct and indirect impact of ICT systems on energy and materials demand, and examines the results of such assessments. In addition, it investigates ICT-based approaches to supporting sustainable patterns of production and consumption, analyzing them at various levels of abstraction – from end-user devices, Internet infrastructure, user behavior, and social practices to macro-economic indicators.   Combining approaches from Computer Science, Information Systems, Human-Computer Interaction, Economics, and Environmental Sciences, the book presents a new, holistic perspective on ICT for Sustainability (ICT4S).

Chen, R. S.; de Sherbinin, A. M.; Yetman, G.; Downs, R. R.

2017-12-01

A central issue in international efforts to address climate change, large-scale disaster risk, and overall sustainable development is the exposure of human settlements and population to changing climate patterns and a range of geological, climatological, technological, and other hazards. The present and future location of human activities is also important in mitigation and adaptation to climate change, and to ensuring that we "leave no one behind" in achieving the Sustainable Development Goals adopted by the international community in September 2015. The extent and quality of built infrastructure are key factors in the mortality, morbidity, and economic impacts of disasters, and are simultaneously essential to sustainable development. Earth observations have great potential to improve the coverage, consistency, timeliness, and richness of data on settlements, infrastructure, and population, in ways that complement existing and emerging forms of socioeconomic data collection such as censuses, surveys, and cell phone and Internet traffic. Night-time lights from the Suomi-NPP satellite may be able to provide near real-time data on occupance and economic activity. New "big data" capabilities make it possible to rapidly process high-resolution (50-cm) imagery to detect structures and changes in structures, especially in rural areas where other data are limited. A key challenge is to ensure that these types of data can be translated into forms useful in a range of applications and for diverse user communities, including national statistical offices, local government planners, development and humanitarian organizations, community groups, and the private sector. We report here on efforts, in coordination with the GEO Human Planet Initiative, to develop new data on settlements, infrastructure, and population, together with open data services and tools, to support disaster risk assessment, climate vulnerability analysis, and sustainable development decision making.

The craniomandibular mechanics of being human

Diminished bite force has been considered a defining feature of modern Homo sapiens, an interpretation inferred from the application of two-dimensional lever mechanics and the relative gracility of the human masticatory musculature and skull. This conclusion has various implications with regard to the evolution of human feeding behaviour. However, human dental anatomy suggests a capacity to withstand high loads and two-dimensional lever models greatly simplify muscle architecture, yielding less accurate results than three-dimensional modelling using multiple lines of action. Here, to our knowledge, in the most comprehensive three-dimensional finite element analysis performed to date for any taxon, we ask whether the traditional view that the bite of H. sapiens is weak and the skull too gracile to sustain high bite forces is supported. We further introduce a new method for reconstructing incomplete fossil material. Our findings show that the human masticatory apparatus is highly efficient, capable of producing a relatively powerful bite using low muscle forces. Thus, relative to other members of the superfamily Hominoidea, humans can achieve relatively high bite forces, while overall stresses are reduced. Our findings resolve apparently discordant lines of evidence, i.e. the presence of teeth well adapted to sustain high loads within a lightweight cranium and mandible. PMID:20554545

Sustainable access to safe drinking water: fundamental human right in the international and national scene

Directory of Open Access Journals (Sweden)

Celso Maran de Oliveira

2017-12-01

Full Text Available Access to potable water is absolutely essential to the maintenance of life, as well as to provide regular exercise of other human rights. The lack of access to water in sufficient quantity or access to non-potable water may cause serious and irreparable damage to people. This paper investigates the evolution of international and national recognition of this fundamental human right, whether implicit or explicit. This was accomplished by the study of international human rights treaties, bibliographic information on water resources and their corresponding legal systems, national and international. The results suggest that sustainable access to drinking water is a fundamental human right in the context of international relations and the State. Further, even without explicitly stating this right in the Constitution of 1988, Brazil has incorporated the main international provisions on the subject, but this right must be acknowledged according to the principles of non-typical fundamental rights and the dignity of the human person. This right should be universally guaranteed by the Government in sufficient quantity and quality, regardless of the economic resources of individuals.

Transition to Sustainability: Science Support Through Characterizing and Quantifying Sustainability

Humanity's sustainability crisis caused by a growing, resource-demanding population on a finite, rapidly changing planet challenges us with large uncertainties. While some see the planet on the edge, it is more likely that humanity as a global species is on the edge. However, science, Earth observations, and socio-economic data do not provide clear indications of where this edge is, and how close we are to this edge. The instruments in the cockpit of a modern airplane provide more relevant and actionable information to the pilots than the "cockpit" of planet Earth provides to those involved in the governance of our planet. There is no manual for those responsible to keep us on a track within the "safe operational space" of humanity. What science and research is needed to make progress towards a future, where knowledge of sustainability and resilience allows for an evidence-based, adaptive policy and decision-making? Paradoxically, innovation over the recent decades have worsened the sustainablity crisis, but more innovation is imperative to bring us out of it. The comprehensive, conceptual framework for sustainability research that would provide an umbrella identifying the key challenges and a basis for this innovation seems to be missing. Defining sustainability as a characteristic of a process that can be maintained at a certain level indefinitely, we need to agree in a societal deliberation on a few aspects, including what processes we want to consider (the anthroposphere as embedded in the Earth system?), what time frames we want to aim at (not infinity, but very long time frames, e.g., 10,000 years?), and what spatial scales we need to look at (from local to global?). Most importantly, we need to acknowledge that humanity's sustainability is the result of intertwined social, economic, and environmental (s2e) processes that can not be separate. The research then has to clarify in the s2e context what are the attributes of sustainability, the relevant processes

Towards Sustainable Health Care Organizations

Mauro ROMANELLI

2017-09-01

Full Text Available Health care organizations have to develop a sustainable path for creating public value by seeking legitimacy for building and maintaining public trust with patients as social and economic institutions creating value and sustaining both health and wealth for people and communities within society. Health care organizations having at disposal decreasing resources and meeting increasing demands of citizens are following an unsustainable path. Designing sustainable health care systems and organizations is emerging as a strategic goal for developing the wealth of people and communities over time. Building sustainable organizations relies on valuing human resources, designing efficient and effective processes, using technology for better managing the relationships within and outside organizations. Sustainable health care organizations tend to rediscover the importance of human resource management and policies for effectively improving communication with patients and building trust-based relationships. While processes of accreditation contribute to legitimizing effectiveness and quality of health care services and efficient processes, introducing and using new information and communication technologies (ICTs and informatics helps communication leading to restore trust-based relationships between health care institutions and patients for value creation within society.

Sustained spheromak coaxial gun operation in the presence of an n=1 magnetic distortion

The Sustained Spheromak Physics Experiment (SSPX) [E. B. Hooper, L. D. Pearlstein, and R. H. Bulmer, Nucl. Fusion 39, 863 (1999)] uses a magnetized coaxial gun to form and sustain spheromaks by helicity injection. Internal probes give the magnetic profile within the gun. An analysis of these data show that a number of commonly applied assumptions are not completely correct, and some previously unrecognized processes may be at work. Specifically, the fraction of the available vacuum flux spanning the gun that is stretched out of the gun is variable and not usually 100%. The n=1 mode that is present during sustained discharges has its largest value of δB/B within the gun, so that instantaneously B within the gun is not axisymmetric. By applying a rigid-rotor model to account for the mode, the instantaneous field and current structure within the gun are determined. The current density is also highly nonaxisymmetric and the local value of λ≡μ 0 j parallel /B is not constant, although the global value λ g ≡μ 0 I g /ψ g closely matches that expected by axisymmetric models. The current distribution near the gun muzzle suggests a cross-field current exists, and this is explained as a line-tying reaction to plasma rotation

Sustainable design is inclusive, holistic and integrative. It require humility and guts, caring and a certain degree of stubbornness. It helps to do it cooperatively in a group. Human interest in sustainability has gained a great deal of impetus over the last several years as the problems of the late 20th and the early 21st century have become clearer. Design for sustainability broadens and integrates many previously separate design concerns to create a unified approach that is both compelling and ripe with new possibilities. Ecosystem regeneration, ecological land use planning, biometric design, regional environmental and economic viability, natural landscape maintenance, resource optimization, integrated infrastructure system, neotraditional and pedestrian oriented urban design, passive solar architecture, appropriate technology, renewable building materials, healthy buildings, and the aesthetics of place; are a few of these design concerns that, when welded together, can create sustainability.

We have designed and performed a new PCR method based on the 18S rRNA in order to individuate the presence and the identity of Babesia parasites. Out of 1159 Ixodes ricinus (Acari: Ixodidae) ticks collected in four areas of Switzerland, nine were found to contain Babesia DNA. Sequencing of the short amplicon obtained (411-452 bp) allowed the identification of three human pathogenic species: Babesia microti, B. divergens, for the first time in Switzerland, Babesia sp. EU1. We also report coinfections with B. sp. EU1-Borrelia burgdorferi sensu stricto and Babesia sp. EU1-B. afzelii.

Wrapping Our Brains around Sustainability

Full Text Available As many of us begin to embrace the concept of sustainability, we realize that it is not simply something that we ‘do.’ Rather, sustainability is a destination that we aspire to reach with the selection of the sustainable pathways that we choose as we proceed along the journey. We are embarking on a new journey with the creation of Sustainability, an on-line, open access journal. As stated on the journal’s website, Sustainability is an international and cross-disciplinary scholarly journal of environmental, cultural, economic and social sustainability of human beings, which provides an advanced forum for studies that are related to sustainability and sustainable development. To genuinely wrap our brains around the impact that our actions have on the sustainability of our planet, we must first understand something of the big picture and have a firm grasp of the terminology. To help further clarify the elusive term ‘sustainability,’ without attempting to provide an exact definition, this paper outlines various, inter-related concepts and basic practices and approaches that are being used in the name of sustainability, including: traditional end-of-pipe control strategies, life cycle, environmental sustainability, urban sustainability, industrial ecology, business sustainability, sustainable supply chain systems, sustainability indicators and metrics, green chemistry and green engineering, design for the environment, sustainable buildings, eco-tourism, and renewable and sustainable energy and fuels.

A Human Rights Lens on Full Employment and Decent Work in the 2030 Sustainable Development Agenda

Directory of Open Access Journals (Sweden)

Diane F. Frey

2016-06-01

Full Text Available On September 25, 2015, the United Nations General Assembly adopted the Sustainable Development Goals (SDGs as the blueprint for a global partnership for peace, development, and human rights for the period 2016 to 2030. The 2030 agenda follows on the heels of the Millennium Development Goals (MDGs, adopted in 2001, which set the international development agenda for the period 2001 to 2015. This article uses a human rights lens to demonstrate that the MDGs and the SDGs have not addressed full employment and decent work in a manner that is consistent with the Decent Work Agenda of the International Labour Organization and international human rights legal obligations of the UN member countries. It concludes that the new 2030 development agenda sadly aligns with market-based economic growth strategies rather than the realization of the human rights to full employment and decent work for all.

The challenge of sustainability

International Nuclear Information System (INIS)

Orr, D.W.

1993-01-01

This paper discusses sustainability in a world that has changed rapidly. The author suggests that ecological assumptions embedded in communism and capitalism are badly flawed, but the flaws were not apparent when there were fewer than a billion people on earth living at low technology levels. Sustaining the earth's vital signs is a challenge to our perception of time, and the numbers - population, environmental damage, oil consumption, waste disposal - are too large to comprehend easily. There is a global debate about what sustainability means. In fact the challenge of sustainability is 6 different challenges: overcoming the tendency to deny inconvenient realities; establishing accurate indicators of human and ecological health; questions about the kinds of technology necessary to make the transition to sustainability; education; the need for an emotional bond between man and nature; rebuilding the existing democratic institutions. 16 refs

Physical Geography and Environmental Sustainability

Mary Thornbush

2017-11-01

Full Text Available In this introduction to the Special Issue on Physical Geography and Environmental Sustainability, the links between a variety of physical landscapes located throughout the world and long-term wellbeing are considered from a systems approach. Twelve papers were published as part of this call, with half from Asia, especially China. They represent a contribution across topographic landscapes, from mountainous to estuarine, and cover models as well as case studies encompassing landscape and environmental changes. Remotely sensed data, statistical analysis, and GIS were often incorporated in the work, and this particularly conveys the importance of spatial analysis on inputs by physical geographers in sustainability research. Furthermore, scale variations from the local to global are presented as part of a geographical contribution. The connectedness of environments to humans and the reverse (of humans adapting to environmental change is evident in several of the papers where human impacts and adaptation are concerned. Finally, the last paper provides a comprehensive summary of the potential contribution that physical geographers can make to environmental sustainability from a multidisciplinary approach.

2018-03-01

Full Text Available The theoretical basis of the concepts of corporate social responsibility and sustainable development are studied. It is revealed that scientists mainly distinguish two main stages in the evolution of the concept of corporate social responsibility. There argued the expediency of singling out the third stage of the development of the concept (version CSR 2.0, which is characterized by the integration of the theoretical and practical foundations of the concepts of CSR and sustainable development as well as by their implementation into activities of corporations. The presence of the necessary prerequisites for singling out the new stage in the evolution of these concepts (version CSR 3.0, which is based on the provisions of the collaborative theory and provides for the cooperation of social enterprises and sustainable corporations in achieving the goals of sustainable development, is revealed, its expediency is justified. The determinant of the stage is the use of opportunities for sustainable development, the dominant is the social orientation, and its content is characterized by the slogan “doing common good to do common well”. Using generalization, there identified the features of the established models of sustainable development of corporations by key aspects (goals, principles, methods. On this basis, the features of approaches to financing sustainable development at the macro and micro levels are determined, and the principles for financing the activities of corporations in the new conditions are defined. It is concluded that achieving sustainability requires an effective system of financing corporate measures aimed at sustainable development, for the creation of which in Ukraine it is necessary to use the experience of “best practices” at the national, local and corporate levels.

Assessing Sustainable Behavior and its Correlates: A Measure of Pro-Ecological, Frugal, Altruistic and Equitable Actions

2013-02-01

Full Text Available Measures of sustainable behavior (SB usually include the self-report of activities aimed at the conservation of the natural environment. The sustainability notion explicitly incorporates both the satisfaction of human needs and the need of conserving the natural environment. Yet, the assessment of sustainable behaviors rarely considers the protection of the social environment as situation to investigate. In this paper, we propose the use of an instrument assessing SB, which includes the report of pro-ecological and frugal actions in addition to altruistic and equitable behaviors. The responses provided by 807 Mexican undergraduates to a questionnaire investigating those four instances of SB were processed within a structural equation model. Emotional (indignation due to environmental destruction, affinity towards diversity, happiness and rational (intention to act factors assumedly linked to sustainable behavior were also investigated. Significant interrelations among pro-ecological, frugal, altruistic and equitable behaviors resulted, suggesting the presence of a higher-order-factor that we identified as SB. This factor, in turn, significantly correlated with the rest of the investigated pro-environmental factors.

Sustainability of common pool resources.

Timilsina, Raja Rajendra; Kotani, Koji; Kamijo, Yoshio

2017-01-01

Sustainability has become a key issue in managing natural resources together with growing concerns for capitalism, environmental and resource problems. We hypothesize that the ongoing modernization of competitive societies, which we refer to as "capitalism," affects human nature for utilizing common pool resources, thus compromising sustainability. To test this hypothesis, we design and implement a set of dynamic common pool resource games and experiments in the following two types of Nepalese areas: (i) rural (non-capitalistic) and (ii) urban (capitalistic) areas. We find that a proportion of prosocial individuals in urban areas is lower than that in rural areas, and urban residents deplete resources more quickly than rural residents. The composition of proself and prosocial individuals in a group and the degree of capitalism are crucial in that an increase in prosocial members in a group and the rural dummy positively affect resource sustainability by 65% and 63%, respectively. Overall, this paper shows that when societies move toward more capitalistic environments, the sustainability of common pool resources tends to decrease with the changes in individual preferences, social norms, customs and views to others through human interactions. This result implies that individuals may be losing their coordination abilities for social dilemmas of resource sustainability in capitalistic societies.

Corporate sustainability: the environmental design and human resource management interface in healthcare settings.

Sadatsafavi, Hessam; Walewski, John

2013-01-01

Purpose of the Paper: The purpose of this study is to provide healthcare organizations with a new perspective for developing strategies to enrich their human resource capabilities and improve their performance outcomes. The focus of this study is on leveraging the synergy between organizational management strategies and environmental design interventions. This paper proposes a framework for linking the built environment with the human resource management system of healthcare organizations. The framework focuses on the impact of the built environment regarding job attitudes and behaviors of healthcare workers. Research from the disciplines of strategic human resource management, resource-based view of firms, evidence-based design, and green building are utilized to develop the framework. The positive influence of human resource practices on job attitudes and behaviors of employees is one mechanism to improve organizational performance outcomes. Organizational psychologists suggest that human resource practices are effective because they convey that the organization values employee contributions and cares about their well-being. Attention to employee socio-emotional needs can be reciprocated with higher levels of motivation and commitment toward the organization. In line with these findings, healthcare environmental studies imply that physical settings and features can have a positive influence on job attitudes and the behavior of caregivers by providing for their physical and socio-emotional needs. Adding the physical environment as a complementary resource to the array of human resource practices creates synergy in improving caregivers' job attitudes and behaviors and enhances the human capital of healthcare firms.

Over the last two centuries, the impact of the Human System has grown dramatically, becoming strongly dominant within the Earth System in many different ways. Consumption, inequality, and population have increased extremely fast, especially since about 1950, threatening to overwhelm the many critical functions and ecosystems of the Earth System. Changes in the Earth System, in turn, have important feedback effects on the Human System, with costly and potentially serious consequences. However, current models do not incorporate these critical feedbacks. We argue that in order to understand the dynamics of either system, Earth System Models must be coupled with Human System Models through bidirectional couplings representing the positive, negative, and delayed feedbacks that exist in the real systems. In particular, key Human System variables, such as demographics, inequality, economic growth, and migration, are not coupled with the Earth System but are instead driven by exogenous estimates, such as United Nations population projections. This makes current models likely to miss important feedbacks in the real Earth–Human system, especially those that may result in unexpected or counterintuitive outcomes, and thus requiring different policy interventions from current models. The importance and imminence of sustainability challenges, the dominant role of the Human System in the Earth System, and the essential roles the Earth System plays for the Human System, all call for collaboration of natural scientists, social scientists, and engineers in multidisciplinary research and modeling to develop coupled Earth–Human system models for devising effective science-based policies and measures to benefit current and future generations.

The coastal zone of the Pacific Rim is home for about one-third of the world’s population. Disproportionate growth of Far Eastern economies has produced a disproportionate share of related environmental difficulties. As the region searches for acceptable compromises between growth and environmental quality, its influence on global environmental health is certain to increase. Consequences of global environmental change such as habitat alteration, storms, and sealevel rise will be particularly acute among Pacific Rim nations. Adverse health effects from arsenic exposure in Pacific Rim nations have been used to justify drinking water standards in the United States and elsewhere. As global manufacturing in the Pacific Rim increases, the centroid of global air quality and waste management issues will shift further toward Far Eastern nations. The Eleventh International Conference of the Pacific Basin Consortium (PBC) was held in September 2005 in Honolulu, Hawaii. The purpose of the conference was to bring together individuals to discuss regional challenges to sustainable growth. The historic emphasis of the conference on hazardous wastes in relation to human health makes the PBC an ideal forum for discussing technical aspects of sustainable economic growth in the Pacific region. That role is reflected in the 2005 PBC conference themes, which included management of arsenic in potable waters, air quality, climate change, pesticides, mercury, and electronics industry waste—each with emphasis on relationships to human health. Arsenic management exemplifies the manner in which the PBC can focus interdisciplinary discussion in a single technical area. The conference program provided talks on arsenic toxicology, treatment technologies, management of arsenic-bearing residuals from water treatment, and the probable societal costs and benefits of arsenic management.

As global manufacturing in the Pacific Rim increases, the centroid of global air quality and waste management issues will shift further toward Far Eastern nations. The Eleventh International Conference of the Pacific Basin Consortium (PBC) was held in September 2005 in Honolulu, Hawaii. The purpose of the conference was to bring together individuals to discuss regional challenges to sustainable growth. The historic emphasis of the conference on hazardous wastes in relation to human health makes the PBC an ideal forum for discussing technical aspects of sustainable economic growth in the Pacific region. That role is reflected in the 2005 PBC conference themes, which included management of arsenic in potable waters, air quality, climate change, pesticides, mercury, and electronics industry waste-each with emphasis on relationships to human health. Arsenic management exemplifies the manner in which the PBC can focus interdisciplinary discussion in a single technical area. The conference program provided talks on arsenic toxicology, treatment technologies, management of arsenic-bearing residuals from water treatment, and the probable societal costs and benefits of arsenic management.

Sustainable practices meet the needs of the present without compromising the ability of future generations to meet their needs. Applying these concepts to food and feed production, nutritional sustainability is the ability of a food system to provide sufficient energy and essential nutrients required to maintain good health in a population without compromising the ability of future generations to meet their nutritional needs. Ecological, social, and economic aspects must be balanced to support the sustainability of the overall food system. The nutritional sustainability of a food system can be influenced by several factors, including the ingredient selection, nutrient composition, digestibility, and consumption rates of a diet. Carbon and water footprints vary greatly among plant- and animal-based ingredients, production strategy, and geographical location. Because the pet food industry is based largely on by-products and is tightly interlinked with livestock production and the human food system, however, it is quite unique with regard to sustainability. Often based on consumer demand rather than nutritional requirements, many commercial pet foods are formulated to provide nutrients in excess of current minimum recommendations, use ingredients that compete directly with the human food system, or are overconsumed by pets, resulting in food wastage and obesity. Pet food professionals have the opportunity to address these challenges and influence the sustainability of pet ownership through product design, manufacturing processes, public education, and policy change. A coordinated effort across the industry that includes ingredient buyers, formulators, and nutritionists may result in a more sustainable pet food system.

Human Value, Dignity, and the Presence of Others.

Hernandez, Jill Graper

2015-09-01

In the health care professions, the meaning of--and implications for--'dignity' and 'value' are progressively more important, as scholars and practitioners increasingly have to make value judgments when making care decisions. This paper looks at the various arguments for competing sources of human value that medical professionals can consider--human rights, autonomy, and a higher-order moral value--and settles upon a foundational model that is related to (though distinct from) the Kantian model that is popular within the medical community: human value is foundational; human dignity, autonomy, and rights derive from the relational quality of human dignity. Moral dignity is expressed though the relationships we cultivate, the communal ends we pursue, and the rights we enjoy. Correlatively, human dignity is inseparable from its ground (i.e., morality), and the relationship between these two is best represented for Kant in the humanities formulation. The foundational model of dignity ensures that human value is non-circularly derived, but is ultimately tied to expressions of individual human dignity that comes from the dignity of morality. Linking Kant's dignity of humanity to the dignity of morality affords a unique and efficacious response to the discussion of human value. In one sense, dignity is amplificatory, since its worth is inextricable with that of autonomy and the rights afforded to the autonomous. But that isn't to say that the worth of dignity is merely amplificatory. Rather, human dignity indicates the absolute inner value (MM 6:435) found in each individual in virtue of being human (MM 6:435, 462). That inner worth engenders certain universal rights--derivable from the dignity and fundamental rational appeal of morality--just as it provides for the possibility for a community of beings to seek to live the moral life.

Sustainable spatial development in higher education

Full Text Available Sustainable development is not only a great challenge for society as a whole, but also for higher education institutions, which have been rapidly including sustainable development in their educational process in the last two decades. Directly or indirectly, education for sustainable spatial development includes all aspects of sustainable development: environmental, economic, social and cultural. Space is a junction of various interests, which requires coordinating the entire process of spatial planning, taking into account the goal of sustainable spatial development. The existing values of space are insufficient for the rapid implementation of a sustainable spatial development paradigm. Suitable education is needed by both individuals and spatial planning professionals and at all levels of education. It is therefore necessary to transform some of the academic programs in the higher education curriculum by integrating teaching content and methods that include long-term knowledge and holistic thinking, taking into account the importance of interdisciplinary integration. This article reviews literature in sustainable development in higher education from 2002 to 2013. Topics discussed include students’ and teachers’ conceptions of sustainable development, the presence of sustainable development and sustainable spatial development in higher education and the reasons for the slow introduction of this material into the curriculum. Based on a literature analysis, the last section identifies important drivers that can contribute to a more rapid integration of a sustainable spatial development paradigm into higher education.

({sup 125}I) Iodosulpride binding was examined on eight human cell lines derived from lung, breast and digestive tract carcinomas, neuroblastomas and leukemia. Specific binding was detected in five of these cell lines. In the richest cell line N417, derived from small cell lung carcinoma, ({sup 125}I) iodosulpride bound with a high affinity (Kd = 1.3 nM) to an apparently homogeneous population of binding site (Bmax = 1,606 sites per cell). These sites displayed a typical D-2 specificity, established with several dopaminergic agonists and antagonists selective of either D-1 or D-2 receptor subtypes. In addition, dopamine, apomorphine and RU 24926 distinguished high- and low-affinity sites, suggesting that the binding sites are associated with a G-protein. The biological significance and the possible diagnostic implication of the presence of D-2 receptors on these cell lines are discussed.

Human Papilloma Virus (HPV) infection can be a predisposing condition for the development of squamous cell papilloma (SCP) of the esophagus, which can progress to dysplasia and to carcinoma as a result of chronic infection. The aim of the present study was to search for the presence of HPV in the esophageal SCP, and to genotype the detected HPV. Data from patients with definite diagnosis of SCP of the esophagus were identified from pathology records for two years period at different Hospitals. Slides from each patient were reviewed and samples with satisfactory papilloma tissues were submitted to molecular analysis. DNA has been isolated. DNA sequencing has been performed for genotyping HPV for all types. Our study group consisted of 21 women and 17 men (a total of 38 patients), mean age was 41 years (range 17-67 years). Most of the papillomas were located at mid-esophagus (68%). Eight out of 38 patients (21%) had associated erosive esophagitis, and fourteen patients (36.8%) had Helicobacter Pylori (H. pylori). Of the 38 SCP analyzed, seven (19%) were positive for HPV DNA. Three of them were of genotype 6, whereas four were of genotype 16, 18, 31, 81 that are known as highly oncogenic. There were no correlations between the presence of HPV and the patient's age, the presence of reflux esophagitis or H. pylori, smoking habit and the location of the papillomas. The presence of high-risk type HPV in esophageal SCP may implicate a role of the virus in the pathogenesis of the esophageal tumor.

Critical factors for sustainable food procurement in zoological collections.

Food procurement can play an important role in sustainable food supply chain management by zoos, linking organizational operations to the biodiversity conservation and sustainability mission of zoological collections. This study therefore examines the critical factors that shape sustainable food procurement in zoo and aquariums. Using a web-based survey data was collected from 41 members of the British and Irish Association of Zoos and Aquariums (BIAZA). This included information on the sustainable food procurement practices of these institutions for both their human and animal food supply chains, as well as profile information and data on the factors contributing to and inhibiting sustainable procurement practices. Zoological collections operated by charities, and those with a certified sustainability standard, were found to have significantly higher levels of sustainable food procurement. Zoos and aquariums whose human food operations were not contracted to an external party were also found to have significantly higher levels of sustainable food procurement in their human food supply chain. The most important drivers of sustainable food procurement were cost savings, adequate financial support and improved product quality. The highest ranking barriers were higher costs, other issues taking priority and a lack of alternative suppliers. The results suggest that a number of critical factors shape sustainable food procurement in zoological collections in the British Isles. Financial factors, such as cost savings, were important considerations. The significance of mission-related factors, such as charity status, indicated that core values held by zoos and aquariums can also influence their food procurement practices. © 2015 Wiley Periodicals, Inc.

The Knowledge Society: A Sustainability Paradigm

Directory of Open Access Journals (Sweden)

Naim Hamdija Afgan

2010-10-01

Full Text Available This paper defines the knowledge society as a human structured organisation based on contemporary developed knowledge and representing new quality of life support systems. It implies the need for a full understanding of distribution of knowledge, access to information and the capability to transfer information into a knowledge. The understanding of knowledge is the central challenge when defining a knowledge society. From our present perception of knowledge society, it is of interest to emphasize the role of the knowledge society in future development of human society. The life support systems are essential pillars of human society development. In this respect knowledge society represents a new paradigm for future development and it is strongly correlated to sustainable development. For this reason the sustainability paradigm of knowledge society is a potential frame for human society development leading to social cohesion, economic competitiveness and stability, use of resources and economic development, safeguarding biodiversity and the ecosystem.In order to verify the mutual relation between knowledge society and sustainability, we have to introduce the difference between these two terms. The knowledge society is based on the agglomeration of eco-knowledge, env-knowledge and soc-knowledge, it may be evaluated as the complex knowledge of quality of life support systems. We have to introduce metrics which will allow us to present knowledge as the paradigm of the number of indicators for verifying progress made.Sustainability metrics are designed to consolidate measures of economic, environmental and social performance of any system. It can be understood as a pattern for evaluation of the available knowledge about systems and their performance. In particular the decision-making process for the selection of the system under consideration must be based on the available knowledge. The link between knowledge and sustainability makes it possible for

Despite substantial focus on sustainability issues in both science and politics, humanity remains on largely unsustainable development trajectories. Partly, this is due to the failure of sustainability science to engage with the root causes of unsustainability. Drawing on ideas by Donella Meadows, we argue that many sustainability interventions target highly tangible, but essentially weak, leverage points (i.e. using interventions that are easy, but have limited potential for transformational change). Thus, there is an urgent need to focus on less obvious but potentially far more powerful areas of intervention. We propose a research agenda inspired by systems thinking that focuses on transformational 'sustainability interventions', centred on three realms of leverage: reconnecting people to nature, restructuring institutions and rethinking how knowledge is created and used in pursuit of sustainability. The notion of leverage points has the potential to act as a boundary object for genuinely transformational sustainability science.

Agroecology and Sustainable Agriculture

Fabio Caporali

Full Text Available In the framework of the 16th National Meeting of the Italian Ecological Society (“Global Change, Ecological Diversity and Sustainability”, University of Tuscia, Viterbo, 19-22 September 2006, a symposium was devoted to “Agroecology and Sustainable Development”. A major goal of this symposium was to contribute to keeping the dialogue among the experts of the various disciplines alive. Sustainability of agriculture is a challenge for society world wide. Universities and society as a whole have a responsibility in re-examining current perception of nature, of the world and of human society in the light of natural resources depletion, increasing pollution and social inequalities. The urgency to address sustainability issues is increasingly being reflected in the manner in which institutions of higher education around the world are giving priority to the teaching, research and practice of sustainability. The University of Tuscia is involved in international initiatives concerning teaching and research in Agroecology and Sustainable Agriculture.

APPROACHES FOR SUSTAINABLE MANUFACTURING

2007-01-01

Sustainable development is a holistic approach harmonizing ecological, economical and socio-political needs with respect to the superior objective of enhancing human living standards. Thereby the availability of natural resources and the conservation of the ecosystems have to be considered that future generations have the possibility to meet their own needs. A long-term economical development demands the transition from a source-sink economy to a cycle economy as a result of limited resources, limited environmental capacities to absorb waste and emissions as well as increasing needs of a growing population. A reference model for sustainability in manufacturing is presented and used to illustrate sustainable approaches with respect to management, technology, process and product. Adaptation of products and components is a vital element for supporting efficient reuse of products and components. Consequently adaptation contributes to the ambitious goals of sustainability. Technological enablers for adaptation as modularity, information and communication technology are exemplarily introduced. Moreover, approaches for disseminating knowledge in sustainability are given.

Kumar, Prakash; Kumar, Anil; Racic, Vitomir; Erlicher, Silvano

2018-01-01

This paper proposes a model of a self-sustained oscillator which can generate reliably the vertical contact force between the feet of a healthy pedestrian and the supporting flat rigid surface. The model is motivated by the self-sustained nature of the walking process, i.e. a pedestrian generates the required inner energy to sustain its repetitive body motion. The derived model is a fusion of the well-known Rayleigh, Van der Pol and Duffing oscillators. Some additional nonlinear terms are added to produce both the odd and even harmonics observed in the experimentally measured force data. The model parameters were derived from force records due to twelve pedestrians walking on an instrumented treadmill at ten speeds using a linear least square technique. The stability analysis was performed using the energy balance method and perturbation method. The results obtained from the model show a good agreement with the experimental results.

Towards an Agent Based Framework for Modelling Smart Self-Sustainable Systems

Igor Tomičić

2015-01-01

Full Text Available Self-sustainability is a property of a system; a system is considered to be self-sustainable if it can sustain itself without external support in an observed period of time. If this property is mapped to a human settlement in context of resources (water, energy, food, etc., it would describe a human settlement which is independent of external resources (like the national electrical grid or a central water distribution system, where such external resources are either not available, or not desirable. This article contributes to presenting the state-of-the-art overview of self-sustainability-related research. While self-sustainability as in the above described form was not a direct subject of research, there are several fields which are either related to, or could be of significant value to the self-sustainability research in this context. The extensive literature overview also showed no frameworks for modeling self sustainable systems in the context of human settlements. Herein a motivation for using agent-based modeling and simulation techniques will be given.

“Sustainability Learning”: An Introduction to the Concept and Its Motivational Aspects

Directory of Open Access Journals (Sweden)

Ralf Hansmann

2010-09-01

Full Text Available This theoretical paper clarifies the concept of sustainability learning and specifically analyzes motivational aspects. Mastering the challenges of sustainability requires individual learning as well as learning processes on different levels of human systems ranging from groups and organizations to human societies, and mankind as a whole. Learning processes of individuals play a fundamental role, since individuals constitute and shape the larger social aggregates. Learning processes on the level of social aggregates are important since social systems embed and influence individuals. Therefore, sustainability learning needs to be understood as a multi-level concept, comprising individual learning as well as learning processes of human systems. Transdisciplinarity and mutual learning between science and society are considered fundamental approaches of sustainability learning, and hence increase the capacity of mankind to manage human-environment systems in sustainable ways. Based on systemic considerations, the two-fold role, in which motivations act as determinants and targeted outcomes of sustainability learning processes, is explained together with the outstanding role that cooperation, hence cooperative motivation, plays for sustainable development. Finally, the multifaceted, controversial discourses on what sustainability ultimately means (for the scientific community, for a given cultural or political entity, organization, or individual person are considered.

Sustainable System for Residual Hazards Management

International Nuclear Information System (INIS)

Kevin M. Kostelnik; James H. Clarke; Jerry L. Harbour

2004-01-01

Hazardous, radioactive and other toxic substances have routinely been generated and subsequently disposed of in the shallow subsurface throughout the world. Many of today's waste management techniques do not eliminate the problem, but rather only concentrate or contain the hazardous contaminants. Residual hazards result from the presence of hazardous and/or contaminated material that remains on-site following active operations or the completion of remedial actions. Residual hazards pose continued risk to humans and the environment and represent a significant and chronic problem that require continuous long-term management (i.e. >1000 years). To protect human health and safeguard the natural environment, a sustainable system is required for the proper management of residual hazards. A sustainable system for the management of residual hazards will require the integration of engineered, institutional and land-use controls to isolate residual contaminants and thus minimize the associated hazards. Engineered controls are physical modifications to the natural setting and ecosystem, including the site, facility, and/or the residual materials themselves, in order to reduce or eliminate the potential for exposure to contaminants of concern (COCs). Institutional controls are processes, instruments, and mechanisms designed to influence human behavior and activity. System failure can involve hazardous material escaping from the confinement because of system degradation (i.e., chronic or acute degradation) or by external intrusion of the biosphere into the contaminated material because of the loss of institutional control. An ongoing analysis of contemporary and historic sites suggests that the significance of the loss of institutional controls is a critical pathway because decisions made during the operations/remedial action phase, as well as decisions made throughout the residual hazards management period, are key to the long-term success of the prescribed system. In fact

Geography, sustainability and the concept of glocalization

Directory of Open Access Journals (Sweden)

Herman Theodoor Verstappen

2010-06-01

Full Text Available Sustainability focuses on the question whether our planet can sustain the present and future global human impact. The related environmental issues and particularly global changes, such as increasing temperatures, rising sea level, deforestation and deteriorating biodiversity, have become a key subject in earth science research. The social and economic components of sustainability, however, get less scientific attention and are often ignored in political and religious circles. Emphasis is on the symptoms of the issue rather than on coping strategies. Are the growing population numbers and social discrepancies compatible with sustainability and is the free market economy of our consumption society compatible with the ecological limits of growth, social balance and human aspirations? Sustainable development is a realistic concept only if its economic aspects are shouldered by social and environmental considerations and if regional and local diversity is respected. The globalization required today thus should be coupled with decentralized glocalization. In this interdisciplinary field of regional differentiation geography can make important contributions. Earth observation from satellites and data handling using geoinformation systems are essential tools.

Energy and Sustainable Development

2013-01-01

None of the eight Millennium Development Goals (MDGs) adopted by the United Nations in 2000 directly addressed energy, although for nearly all of them - from eradicating poverty and hunger to improving education and health - progress has depended on greater access to modern energy. Thirteen years later, energy is being given more attention. The target date for the MDGs is 2015, and in 2012 the UN began deliberations to develop sustainable development goals to guide support for sustainable development beyond 2015. The Future We Want, the outcome document of the 2012 United Nations Conference on Sustainable Development (also known as Rio+20) gives energy a central role: ''We recognize the critical role that energy plays in the development process, as access to sustainable modern energy services contributes to poverty eradication, saves lives, improves health and helps provide for basic human needs''

There is a growing concern about how to minimize the impact of human activities on the environment. Already nowadays, in some places adaptation efforts are needed in order to avoid the irreversibility of negative human activities. Due to climate changes, and corresponding environmental and social changes, there is a great need for a more sustainable development of mankind. Over the years, research studies that analyzed the sustainable development of different communities with a multi-disciplinary approach, stressed the necessity of preserving the environment for next generations. Therefore, responsible and conscientious management of the environment is a pillar of the sustainable development concept. This review introduction article provides an overview of the recent top scientific publications related to sustainable development that mostly originated from previous SDEWES conferences.

Techno-ecological synergy: a framework for sustainable engineering.

Bakshi, Bhavik R; Ziv, Guy; Lepech, Michael D

2015-02-03

Even though the importance of ecosystems in sustaining all human activities is well-known, methods for sustainable engineering fail to fully account for this role of nature. Most methods account for the demand for ecosystem services, but almost none account for the supply. Incomplete accounting of the very foundation of human well-being can result in perverse outcomes from decisions meant to enhance sustainability and lost opportunities for benefiting from the ability of nature to satisfy human needs in an economically and environmentally superior manner. This paper develops a framework for understanding and designing synergies between technological and ecological systems to encourage greater harmony between human activities and nature. This framework considers technological systems ranging from individual processes to supply chains and life cycles, along with corresponding ecological systems at multiple spatial scales ranging from local to global. The demand for specific ecosystem services is determined from information about emissions and resource use, while the supply is obtained from information about the capacity of relevant ecosystems. Metrics calculate the sustainability of individual ecosystem services at multiple spatial scales and help define necessary but not sufficient conditions for local and global sustainability. Efforts to reduce ecological overshoot encourage enhancement of life cycle efficiency, development of industrial symbiosis, innovative designs and policies, and ecological restoration, thus combining the best features of many existing methods. Opportunities for theoretical and applied research to make this framework practical are also discussed.

Indian agriculture has achieved remarkable success in the food grain production due to inception of 'rainbow revolution', which made the country self-sufficient in food production. Sustainable agriculture (SA) is an ongoing process, in which people take actions leading to development of agriculture that meets their current needs without compromising the ability of future generations to meet their needs. It advocates avoiding all those actions, which reduce the ability of future generations to meet out the present generations. It is based on the optimal interaction between clean environment, healthy economy, and vital society by avoiding trade-off of problems to other regions on to the future. Moreover, sustainable agriculture is the function of people's progress and nature's capacity. In fact, SA commits us to considering the long-term effect and to recognize our place within the ecosystem. It encourages a continuous reflection on the implications of human activity on the ecosystem. Empirical evidences shows that in the race of self-sufficiency in food grain production, we compromised a lot on social and environmental fronts. The aftermath of green revolution is not so sustainable as it showed reverse side too, in the form of environmental degradation and ecological imbalances. Such threats have led to the need for promoting sustainable development in agriculture. Due to several unsustainable activities which resulted in resource degradation in the form of top soil loss, ground water depletion and forest degradation. The average soil loss is estimated to be over 16 tonnes/ha/year. The ground water depletion resulted in several blocks as 'grey blocks' and 'dark blocks'. This happened mainly due to increase in number of tube-wells and free supply of electricity making the cost of pumping water very low. Rate of human induced land degradation is very high. Out of total geographical area of 329.0 million ha, 187 million ha (57.0 %) are reported to have degraded, of

This article discusses sustainable development, a policy which attempts to balance environmental preservation and economic growth, and promises a way to provide a decent life for Earth's human inhabitants without destroying the global ecosystem. Sustainable development is an effort to use technology to help clean up the mess it helped make, and engineers will be central players in its success or failure. Key aspects include more efficient energy use through conservation measures and switching to renewable sources, waste minimization, much greater recycling and reuse of materials, more comprehensive economic/environmental assessments employing life-cycle analyses, and better management of resources

Serological study on WNV presence in horses in Vojvodina after the human outbreak in Serbia in 2012

Full Text Available To establish the presence of West Nile virus (WNV infection in the animal population in Serbia after the human WNV outbreak, the presence of anti-WNV IgG antibodies was examined by commercial ELISA of blood sera samples of 130 horses collected in 2012 from 6 stables and 1 settlement in Vojvodina Province, northern Serbia. During the blood sampling, hibernating mosquitoes in the vicinity of the sampled horses were collected (31 pools from 4 locations and tested for WNV presence by real-time RT-PCR. The presence of anti-WNV antibodies was observed in 49.23% (64/130 horses. Per stable, the percent of seropositive animals ranged from 35% to 64%. All 31 analyzed pools of hibernating mosquitoes tested negative for WNV RNA. The WNV-antibody prevalence of 49.23% obtained in horses during 2012 was much higher than the prevalence (12% found in horses during 2009/2010. These results, including the confirmed seroconversion in eight horses that tested negative in 2010, indicated an intensive WNV circulation during 2012 in Serbia, and the necessity of implementing surveillance programs.

Recently, the plasmid-mediated colistin resistance gene mcr-1 was found in Enterobacteriaceae from humans, pigs and retail meat in China. Several reports have documented global presence of the gene in Enterobacteriaceae from humans, food animals and food since. We screened several well-characterised strain collections of Enterobacteriaceae, obtained from retail chicken meat and hospitalised patients in the Netherlands between 2009 and 2015, for presence of colistin resistance and the mcr-1 gene. A total of 2,471 Enterobacteriaceae isolates, from surveys in retail chicken meat (196 isolates), prevalence surveys in hospitalised patients (1,247 isolates), clinical cultures (813 isolates) and outbreaks in healthcare settings (215 isolates), were analysed. The mcr-1 gene was identified in three (1.5%) of 196 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli isolates from retail chicken meat samples in 2009 and 2014. Two isolates were obtained from the same batch of meat samples, most likely representing contamination from a common source. No mcr-1-positive isolates were identified among 2,275 human isolates tested. All mcr-1-positive isolates were colistin-resistant (minimum inhibitory concentration (MIC) > 2 mg/L). Our findings indicate that mcr-1-based colistin-resistance currently poses no threat to healthcare in the Netherlands. They indicate however that continued monitoring of colistin resistance and its underlying mechanisms in humans, livestock and food is needed.

Sustainability has become a key issue in managing natural resources together with growing concerns for capitalism, environmental and resource problems. We hypothesize that the ongoing modernization of competitive societies, which we refer to as "capitalism," affects human nature for utilizing common pool resources, thus compromising sustainability. To test this hypothesis, we design and implement a set of dynamic common pool resource games and experiments in the following two types of Nepales...

This paper explores how scientists entangle themselves in between keywords and buzzwords when they make use of concepts like sustainability. It sketches out theoretical distinctions between keywords and buzzwords. Then it turns to the concept of nature discussing the paradox that nature embraces...... the same fuzzy, slippery and contingent character as does sustainability, yet the former has a deep ontological status, the latter does not. The paper explores a related paradox: natural sciences claim we live in the Anthropocene, in which humans have transformed geochemical cycles, e.g. of methane...... and carbon dioxide as much as they changed between glacial and interglacial periods. Yet, science favors (external) nature as a keyword, sustainability as a buzzword. This should cause deep reflections on how scientists make use of the power of reference in between keywords and buzzwords – as well...

Full Text Available Cats are the definitive hosts of Toxoplasma gondii. Infected cats excrete oocysts in their feces, infecting humans and other animals. The objective of the present study was to determine the presence of anti-Toxoplasma antibodies in cat owners and their pets, and determine if there was a relationship between Toxoplasma infection and humans who live with infected cats. IgG anti-Toxoplasma antibodies in sera of 59 cat owners were determined by enzyme-linked immunosorbent assay (ELISA, in 24 sera from their cats, IgG, IgM, and IgA antibodies were found using Burney's ELISA. Thirty-eight (64% of 59 cat owners were positive to IgG anti-Toxoplasma. Seropositivity for cats was 70.8% IgG, 8.3% IgM, and 62.5% IgA. Cohabitation with cats infected by T. gondii, feeding with leftovers or raw viscera, and lack of control over how their feces were handled are risk factors conducive for humans to become infected by T. gondii.

Nutritional Sustainability of Pet Foods12

Swanson, Kelly S.; Carter, Rebecca A.; Yount, Tracy P.; Aretz, Jan; Buff, Preston R.

2013-01-01

Sustainable practices meet the needs of the present without compromising the ability of future generations to meet their needs. Applying these concepts to food and feed production, nutritional sustainability is the ability of a food system to provide sufficient energy and essential nutrients required to maintain good health in a population without compromising the ability of future generations to meet their nutritional needs. Ecological, social, and economic aspects must be balanced to support the sustainability of the overall food system. The nutritional sustainability of a food system can be influenced by several factors, including the ingredient selection, nutrient composition, digestibility, and consumption rates of a diet. Carbon and water footprints vary greatly among plant- and animal-based ingredients, production strategy, and geographical location. Because the pet food industry is based largely on by-products and is tightly interlinked with livestock production and the human food system, however, it is quite unique with regard to sustainability. Often based on consumer demand rather than nutritional requirements, many commercial pet foods are formulated to provide nutrients in excess of current minimum recommendations, use ingredients that compete directly with the human food system, or are overconsumed by pets, resulting in food wastage and obesity. Pet food professionals have the opportunity to address these challenges and influence the sustainability of pet ownership through product design, manufacturing processes, public education, and policy change. A coordinated effort across the industry that includes ingredient buyers, formulators, and nutritionists may result in a more sustainable pet food system. PMID:23493530

2014-07-01

Alaska's 1049-mile Iditarod Trail Sled Dog Race is the world's longest sled dog race and the flagship event in the sport of sled dog racing. Race conditions are typically harsh. Physicians are not officially enlisted to care for human competitors. Instead, medical needs are met through an informal system of volunteers, local health care providers, and a fleet of bush planes. The goals of this study were to identify the types of human injury and illness experienced and the methods by which these conditions are treated. Competitors in the 2010 Iditarod were surveyed at the halfway point and at the finish of the race. Survey elements included specific types and frequencies of injuries and illnesses, and the sources and types of treatments. Seventy-one teams entered the race, 62 participated in the halfway point survey, and 55 completed the finish line survey. Ninety-nine injuries were reported by 42 (68%) of the survey respondents. Frostbite was the most common injury, occurring in 20 (31%) of the respondents. Musculoskeletal pain was also commonly reported. Two mushers sustained closed head injuries, with 1 requiring evacuation. Twenty-three mushers (37%) reported an acute nontraumatic condition, most frequently an upper respiratory infection (9 respondents). In most instances, medical conditions were self-managed. Race veterinarians and support staff, as well as local village clinicians, administered the majority of care, typically wound care or oral antibiotic administration. Most injuries and illnesses sustained by mushers in the Iditarod are minor and self-treatable. Life-threatening conditions are rare, and the need for an organized medical care system seems low.

Modeling Sustainable Food Systems.

Allen, Thomas; Prosperi, Paolo

2016-05-01

The processes underlying environmental, economic, and social unsustainability derive in part from the food system. Building sustainable food systems has become a predominating endeavor aiming to redirect our food systems and policies towards better-adjusted goals and improved societal welfare. Food systems are complex social-ecological systems involving multiple interactions between human and natural components. Policy needs to encourage public perception of humanity and nature as interdependent and interacting. The systemic nature of these interdependencies and interactions calls for systems approaches and integrated assessment tools. Identifying and modeling the intrinsic properties of the food system that will ensure its essential outcomes are maintained or enhanced over time and across generations, will help organizations and governmental institutions to track progress towards sustainability, and set policies that encourage positive transformations. This paper proposes a conceptual model that articulates crucial vulnerability and resilience factors to global environmental and socio-economic changes, postulating specific food and nutrition security issues as priority outcomes of food systems. By acknowledging the systemic nature of sustainability, this approach allows consideration of causal factor dynamics. In a stepwise approach, a logical application is schematized for three Mediterranean countries, namely Spain, France, and Italy.

ZHENG Du; DAI Erfu

2012-01-01

The scientific environmental ethics plays a key role in the recognition of the human-environment interactions.Modern environmental ethics is the philosophical re-thinking of modern human race environmental behavior.The development of environmental ethics theory,as well as its application in reality,determines the viewpoints of environmental ethics.Sustainable development implies harmony on human-environment interactions and inter-generation responsibility,with emphasis on a harmonious relationship among population,resources,environment and development,so as to lay a sustainable and healthy foundation of resources and environment for future generations.The harmonious society construction in China that is raised by the Chinese central government should be covered by environmental ethics.The connotation of open environmental ethics includes a respect for nature,care for the individual human race,and respect for the development of future generations,which means giving consideration to natural values,individual and human race benefits and welfare across generations.The role of environmental ethics in regional development consists of cognition,criticism,education,inspiration,adjusting,legislation and promoting environmental regulations.The major problems in regional development are extensive resource exploration,fast population growth,irrational industrial structure,unfair welfare distribution and the twofold effects of science and technology development.The formulation of environmental ethics that aims at regional sustainable development,can not only harmonize the relationship of population,resource,environment and economic development,but also guide behavior selection,push social and political system transformation,strengthen the legal system,and raise environmental awareness of the public.

Full Text Available Abstract. Conformational changes of human serum γ–globulin during interaction with the zinc ions were studied in a solution. It has been shown that the presence of zinc in over its physiological concentrations led to increase in optical density across the whole spectrum of γ–globulin ultraviolet absorption. On the contrary, hypochromia in the spectrum was registered after interaction of the protein with zinc used in subphisiological concentrations. Possible role of divalent metal cations in changes in conformation of the blood serum γ–globulins, and thereby in regulation of their effector functions was discussed. (Med.

Entropy Analysis of the Coupled Human–Earth System: Implications for Sustainable Development

Directory of Open Access Journals (Sweden)

Weifang Shi

2017-07-01

Full Text Available Finding the basic physical foundation contributing to sustainable development is significantly useful in seeking ways to build an enduring human future. This paper introduces the dissipative structure theory to analyze the entropy budgets of the whole coupled human–Earth system and the key processes of the subsystems, and then presents the formulas to calculate these entropy budgets. The results show that the total net negative entropy of the coupled human–Earth system from exchange with space is sufficient, but only about 0.0042% of it is available for sustaining the life activities of the whole coupled system and the quantity of this portion is also not more than sufficient compared with the requirement of human life activities. In addition, the rate of negative entropy consumption by human subsystem from fossil fuels for sustaining modern civilization is too large, nearly a half of the negative entropy rate obtained by photosynthesis on the Earth, which indicates that entirely substituting biomass fuels for fossil fuels may be infeasible. The strategies for sustaining human life activities and modern civilization are proposed in the study, which would provide valuable information for humans to realize sustainable development.

SUSTAINABLE DEVELOPMENT, A MULTIDIMENSIONAL CONCEPT

Directory of Open Access Journals (Sweden)

TEODORESCU ANA MARIA

2015-06-01

Full Text Available Sustainable development imposed itself as a corollary of economic term "development". Sustainable development is meant to be the summation of economic, environmental and social considerations for the present and especially for the future. The concept of sustainable development plays an important role in european and global meetings since 1972, the year it has been set for the first time. Strategies necessary to achieve the objectives of sustainable development have been developed, indicators meant to indicate the result of the implementation of policies have been created, national plans were oriented towards achieving the proposed targets. I wanted to highlight the multidimensional character of the concept of sustainable development. Thus, using specialized national and international literature, I have revealed different approaches of one pillar to the detriment of another pillar depending on the specific field. In the different concepts of sustainable development, the consensus is undoubtedly agreed on its components: economic, social, environmental. Based on this fact, the concept of sustainability has different connotations depending on the specific content of each discipline: biology, economics, sociology, environmental ethics. The multidimensional valence of sustainable development consists of three pillars ability to act together for the benefit of present and future generations. Being a multidimensional concept, importance attached to a pillar over another is directed according to the particularities of each field: in economy profit prevails, in ecology care of natural resources is the most important, the social aims improving human living conditions. The challenge of sustainable development is to combine all the economic, environmental and social benefits and the present generation to come. Ecological approach is reflected in acceptance of limited natural resources by preserving natural capital. In terms of the importance of

Environment degradation urges human to live in a sustaining way both for production and consumption mode. It covers any sector of human life include architecture. People are competing to implement the concept of sustainability using the latest technology while the culture has begun to be forgotten. Bearing in mind that by examining the culture related or daily activities, the sustainable development can be implemented with a solid base and fully accepted by the society. Hence, the benefit of sustainable development can be felt by the inhabitant sooner. The aim of this research is examining the local culture in Banda Aceh, Indonesia, and Gozo, Maltese Islands which has sustainability concept. The local culture can be a starting point in implementing the notion of sustainability through daily basis approach. This research uses the qualitative method and collects the data through observation and literature review. The result has shown that some of the cultures in selected area have sustainability values which can be developed further in term of the implementation of sustainable development. Thus, related to the sustainable development, the practitioners can shift to the deep-rooted local value rather than apply an alien concept in society.

Civic Ecology: A Postmodern Approach to Ecological Sustainability

Lopes, V. L.

2013-12-01

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

Deltas are among the most productive and economically important of global ecosystems but unfortunately they are also among the most threatened by human activities. Here we discuss deltas and human impact, several approaches to defining deltaic sustainability and present a ranking of sustainability. Delta sustainability must be considered within the context of global biophysical and socioeconomic constraints that include thermodynamic limitations, scale and embeddedness, and constraints at the level of the biosphere/geosphere. The development, functioning, and sustainability of deltas are the result of external and internal inputs of energy and materials, such as sediments and nutrients, that include delta lobe development, channel switching, crevasse formation, river floods, storms and associated waves and storm surges, and tides and other ocean currents. Modern deltas developed over the past several thousand years with relatively stable global mean sea level, predictable material inputs from drainage basins and the sea, and as extremely open systems. Human activity has changed these conditions to make deltas less sustainable, in that they are unable to persist through time structurally or functionally. Deltaic sustainability can be considered from geomorphic, ecological, and economic perspectives, with functional processes at these three levels being highly interactive. Changes in this functioning can lead to either enhanced or diminished sustainability, but most changes have been detrimental. There is a growing understanding that the trajectories of global environmental change and cost of energy will make achieving delta sustainability more challenging and limit options for management. Several delta types are identified in terms of sustainability including those in arid regions, those with high and low energy-intensive management systems, deltas below sea level, tropical deltas, and Arctic deltas. Representative deltas are ranked on a sustainability range

Ex-Ante Impact Assessment of Sustainability Information–The Directive 2014/95

Directory of Open Access Journals (Sweden)

Cristian Carini

2018-02-01

Full Text Available Directive 2014/95, in force since 2017, is the first European step that requires undertakings to provide mandatory non-financial information. The regulation concerns sustainability information, such as environmental, social, and employee information, human rights, and anti-corruption and bribery matters, and the disclosure of diversity policies for board members. According to the theoretical framework of Integrated Assessment (IA, the study aims to examine the expected impact of the Directive within the analysis of empirical evidence before the mandatory approach. This allows, on the regulatory side, evaluation of the quality of the regulation, therefore, whether the law achieves its policy objectives (i.e., if it fills the gap in the sustainability disclosure and, on the firms’ side, to identify where companies have to invest to meet the legal requirements. The oil and gas sector is chosen as a sample for the study, because it is one of the most advanced sectors in sustainability disclosure, and if the regulation could impact on this sector, it would be the same for less-informed ones. The findings reveal a fair level of completeness of non-financial information, however, there are some areas that have to be improved to achieve the requirements of the Directive. The results also show the presence of overlap between financial and sustainability reports. In conclusion, the quality of regulation is good because it will also increase sustainability disclosure in an advanced sector, such as oil and gas, even if there is an open point on the location of information; companies in this sector will have to invest more in environmental and employee information in future years to comply with the Directive.

The Urban Crisis in Sub-Saharan Africa: A Threat to Human Security and Sustainable Development

Directory of Open Access Journals (Sweden)

Mediel Hove

2013-03-01

Full Text Available Urban centres have existed and have been evolving for many centuries across the world. However, the accelerated growth of urbanisation is a relatively recent phenomenon. The enormous size of urban populations and more significantly, the rapidity with which urban areas have been and are growing in many developing countries have severe social, economic and physical repercussions. This paper argues that the accelerated growth of urbanisation has amplified the demand for key services. However, the provision of shelter and basic services such as water and sanitation, education, public health, employment and transport has not kept pace with this increasing demand. Furthermore, accelerated and poorly managed urbanisation has resulted in various types of atmospheric, land and water pollution thereby jeopardising human security. This paper offers the conclusion that the increased environmental, social and economic problems associated with rapid urbanisation pose a threat to sustainable development, human security and, crucially, peace.

Accounting for Human Health and Ecosystems Quality in Developing Sustainable Energy Products: The Implications of Wood Biomass-based Electricity Strategies to Climate Change Mitigation

Science.gov (United States)

Weldu, Yemane W.

The prospect for transitions and transformations in the energy sector to mitigate climate change raises concerns that actions should not shift the impacts from one impact category to another, or from one sustainability domain to another. Although the development of renewables mostly results in low environmental impacts, energy strategies are complex and may result in the shifting of impacts. Strategies to climate change mitigation could have potentially large effects on human health and ecosystems. Exposure to air pollution claimed the lives of about seven million people worldwide in 2010, largely from the combustion of solid fuels. The degradation of ecosystem services is a significant barrier to achieving millennium development goals. This thesis quantifies the biomass resources potential for Alberta; presents a user-friendly and sector-specific framework for sustainability assessment; unlocks the information and policy barriers to biomass integration in energy strategy; introduces new perspectives to improve understanding of the life cycle human health and ecotoxicological effects of energy strategies; provides insight regarding the guiding measures that are required to ensure sustainable bioenergy production; validates the utility of the Environmental Life Cycle Cost framework for economic sustainability assessment; and provides policy-relevant societal cost estimates to demonstrate the importance of accounting for human health and ecosystem externalities in energy planning. Alberta is endowed with a wealth of forest and agricultural biomass resources, estimated at 458 PJ of energy. Biomass has the potential to avoid 11-15% of GHG emissions and substitute 14-17% of final energy demand by 2030. The drivers for integrating bioenergy sources into Alberta's energy strategy are economic diversification, technological innovation, and resource conservation policy objectives. Bioenergy pathways significantly improved both human health and ecosystem quality from coal

Ethics in environmental politics and sustainable use of the planet

Directory of Open Access Journals (Sweden)

John Cairns Jr.

2001-06-01

Full Text Available ABSTRACT: Environmental politics, especially regarding sustainable use of the planet, must be based on a shared set of ethical values. Although there is a fundamental conflict between ecological doctrine and human cultures, naturalistic assemblages of plants and animals can co-exist with human society in a mutualistic relationship. Numerous environmental practices of human society have ethical implications and are serious obstacles to the quest for sustainability. Continuing them will probably result in crossing one or more important ecological thresholds, which may result in new ecological conditions less favorable to human society than those that presently exist. Some of the probable conditions (e.g., global climate change could be characterized as paradigm-shifting catastrophes. Motivational ethics may triumph initially, but consequential ethics may eventually emerge in environmental politics, which would then produce some interesting conditions in a sustainability context. Since humans have only one planet on which to experiment, speculation about possible future scenarios seems prudent, as does precautionary action to avoid undesirable outcomes.

SUSTAIN: a network model of category learning.

Science.gov (United States)

Love, Bradley C; Medin, Douglas L; Gureckis, Todd M

2004-04-01

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN recruits an additional cluster to represent the surprising event. Newly recruited clusters are available to explain future events and can themselves evolve into prototypes-attractors-rules. SUSTAIN's discovery of category substructure is affected not only by the structure of the world but by the nature of the learning task and the learner's goals. SUSTAIN successfully extends category learning models to studies of inference learning, unsupervised learning, category construction, and contexts in which identification learning is faster than classification learning.

Almas HAMID

Full Text Available Abstract The presence of pesticides in the environment is highly toxic to environment and human health. Aim of the study was determination, quantification and assessment of associated health risk due to presence of pesticide residues in chicken eggs using high pressure liquid chromatography. HPLC method was successfully employed and validated. From collected samples pesticides were extracted in presence of petroleum ether and acetonitrile. Bifenthrin and Difenoconazole residues were found in all samples with different concentration exceeding maximum residue limits (MRL of Codex Alimentarius Commission. However imidacloprid was not detected in any sample. Concentration of bifenthrin in house egg samples ranged from 0.256206 to 4.112387 mg/kg while in poultry farm samples it varied from 1.5862 to 5.80796 mg/kg. Difenoconazole was found in concentration of 0.02835 mg/kg, 1.7668 mg/kg, 3.7205 mg/kg, 21.8937 mg/kg 21.9835 mg/kg, 19.26407 mg/kg in samples collected from houses while and in poultry farm samples its detected concentration was 10.939 mg/kg, 12.3296 mg/kg, 29.3617 mg/kg, 18.6116 mg/kg, 40.0523 mg/kg and 19.2335 mg/kg. Concentrations of both pesticides Bifenthrin and Difenoconazole exceeded the MRLs (0.05 mg/kg. Health risk index surpassed 1 (the cut off value for Difenoconazole in seven samples while for Bifenthrin values were less than 1, indicating the possibility of potential medium to long term health risk associated with ingestion of contaminated eggs.

In this paper a study on the sustainability of the main electricity generation options is presented. The study is based on a matrix of sustainability indicators developed in Switzerland. A revision of some sustainability studies performed in countries with certain energy diversity and with experience in nuclear power plants operation, is done. Studies, in general, are performed for the power plant life cycle, taking into account economic aspects, fuel prices impact on electricity generation costs, fuel reserves indicators and material consumption. Air emission, waste production and human health impact data are also presented. All the results lead to confirm that nuclear energy has a high degree of sustainability vis a vis other options based on fossil fuels and renewable. Finally some comments are presented in order to highlight the importance that nuclear energy might have in the sustainable development of Mexico. (Author)

Full Text Available The popularity created the concept of sustainable development has determined the conviction that tourism can develop in compliance with the philosophy of sustainability. For example, if we compare with other activities such as agriculture, forestry or in other sectors of the economy, tourism has a development relatively recent to human evolution. Tourism place in sustainable development is given the role of this economic activity that "sells" the physical and human environment as a product of his own. Tourism is one of the industries that should be involved in sustainable development, as industry resources, dependency on natural and human potential of cultural heritage in an efficient manner. Tourism "sell" these resources as some parts of his product, but at the same time shares certain resources with other users (local communities, the structure of the central administration. It is essential that tourism to be active in issues of sustainable development and to cooperate with other industries in ensuring the quality and longevity of the resources on which rests the whole tourist activity. Sustainable development in tourism is a necessity, and the connection between tourism and environment is much stronger than in the case of other industries. This paper presents the most important aspects of the rural turism and the contribution which it can bring to the wellbeing of a nation. The author like to stress some elements related to the concept of rural tourism which has nowadays become very important around the world. The rural tourism can revitalise the conventional concepts and views on tourism, and bring in a new dim ension to the sustainable development of tourism. It has been realised that tourism can play a major role in many countries economies, especially in developing ones, where it can substantially contribute to the increase of the national income..

THE ROLE OF ENERGY IN ECOLOGICAL SUSTAINABILITY

2015-07-01

Full Text Available The rapid population growth leads to greater daily demand for energy, causing nations to diversify their portfolios and seek new sources of energy, including renewable to provide more energy. In a universe with seriously exhausted natural resources, severe urbanization, climate change and conflicts that go beyond borders, the issue of overpopulation unquestionably causes worldwide debates and can generate a snowball effect for the global economy or human society. Population’s increase in the nearby future will have a central role in challenges such as: global warming, air and water contamination, increase in the level of poverty, food scarcity, deforestation, desertification, health problems and resource shortages. The transformation into a sustainable environmental model, situated in a post-carbon economy, will imply setting barriers to industrial progress (will have to be sustainable and environmental friendly and also to population growth (will have to follow a normal pace. But, the level on vulnerability and uncertainty in the evolution of energy has been threatened lately by major events that took place all around the world. Security of supply, new geopolitical perspectives and ecological and sustainability issues are yet again on the bleeding line. Therefore, the goal of this theoretical article is to give an overview of the current situation concerning the role of energy in ecological sustainability. It expresses routes in which humans and enterprises can act in order to contribute to ecologically sustainable development. The subject of how we live on a congested planet represents the most critical sustainability of all. We are witnessing our current risks and we can also envision our possible, and particularly desirable, future: a steady human population, living and protecting the nature and planet, having finite needs of goods, services, or energy, and maintaining a healthy Earth for us and the animals that also depend on it.

SUSTAINABLE YACHT TOURISM PRACTICES

Directory of Open Access Journals (Sweden)

Figen SEVİNÇ

2017-06-01

Full Text Available Yacht tourism has become an important asset for the countries which consider tourism as a means of development due to its environment awareness, national and international investments, the volume of business, employment opportunities, foreign exchange income, socio-economic and socio-cultural impact, and an increasing number of investments and incentives for yacht tourism have made and used in a number of countries. In the presence of such rapid developments, the environmental damage caused by yacht tourism has been of importance for coastal countries, and action plans and special projects involving many countries have been developed in order to enhance the awareness of the sustainability of yacht tourism. Given that environment is not a limited source, it is blatant that national or international sustainable tourism practices have been essential for coastal countries and environmental threats are now so severe that they cannot be overlooked. The purpose of the study is to discuss sustainable tourism practices as a part of the measures to eliminate the negative impacts of yacht tourism and provide relevant suggestions.

A territorial understanding of sustainability in public development

Sustainability theories in European Union (EU) development policies are facing significant challenges: it is difficult to transmit context-specific, publicly communicable messages; the recent development policies strengthen the concurrent development paradigm of economic growth and competitiveness; 'climate change' became a more popular environmental integration term than sustainability in the last few years. However, due to the recent crises of the economic growth, there is a great chance to reintroduce a sustainability-based development. A territorial/regional understanding of sustainability can also be an answer for the current challenges, a platform for refreshing the concept with relevant, specific messages that are close to the everyday life. This paper summarises the 'territorial system'-based basic principles of territorial sustainability in a model called AUTHARSIIV (AUTonomy, HARmony, Solidarity, Innovation, Identity and Values). This is a supplementary sustainability content specified for the context of spatial/regional development or planning. The paper also examines the presence of 'general and territorial sustainability' in regional development programmes, and case studies on applying the territorial sustainability principles in planning, assessment, and implementation. According to the results, sustainability is rarely adapted to the conditions of a given sector or a region, and the territorial aspect of sustainability is underrepresented even in territorial programmes. Therefore, the paper proposes a new planning and assessment system that is based on a set of regionally legitimate sustainability values.

Growth hormone in the presence of laminin modulates interaction of human thymic epithelial cells and thymocytes in vitro

Directory of Open Access Journals (Sweden)

Marvin Paulo Lins

Full Text Available BACKGROUND: Several evidences indicate that hormones and neuropeptides function as immunomodulators. Among these, growth hormone (GH is known to act on the thymic microenvironment, supporting its role in thymocyte differentiation. The aim of this study was to evaluate the effect of GH on human thymocytes and thymic epithelial cells (TEC in the presence of laminin. RESULTS: GH increased thymocyte adhesion on BSA-coated and further on laminin-coated surfaces. The number of migrating cells in laminin-coated membrane was higher in GH-treated thymocyte group. In both results, VLA-6 expression on thymocytes was constant. Also, treatment with GH enhanced laminin production by TEC after 24 h in culture. However, VLA-6 integrin expression on TEC remained unchanged. Finally, TEC/thymocyte co-culture model demonstrated that GH elevated absolute number of double-negative (CD4-CD8- and single-positive CD4+ and CD8+ thymocytes. A decrease in cell number was noted in double-positive (CD4+CD8+ thymocytes. CONCLUSIONS: The results of this study demonstrate that GH is capable of enhancing the migratory capacity of human thymocytes in the presence of laminin and promotes modulation of thymocyte subsets after co-culture with TEC.

In the present study, we examined the effect of a very low-calorie diet(VLCD)-based obesity program on human gut microbiome diversity and metabolism during weight loss and weight maintenance. Obese subjects underwent 3 months of VLCD followed by 3 months of weight maintenance. A lean and an obese control group were included. The microbiome was characterized by performing high-throughput dual-indexed 16S rDNA amplicon sequencing. At baseline, a significant difference in the Firmicutes/Bacteroidetes ratio between the lean and obese individuals was observed (p = 0.047). The VLCD resulted in significant alterations in gut microbiome diversity from baseline to 3 months (p = 0.0053). Acinetobacter represented an indicator species for the observed effect (indicator value = 0.998, p = 0.006). Metabolic analyses revealed alterations of the bacterial riboflavin pathway from baseline to 3 months (pnom = 0.0078). These changes in diversity and bacterial metabolism induced by VLCD diminished during the weight maintenance phase, despite sustained reductions in body weight and sustained improvements of insulin sensitivity. The present data show that a VLCD is able to beneficially alter both gut microbiome diversity and metabolism in obese humans, but that these changes are not sustained during weight maintenance. This finding might suggest that the microbiome should be targeted during obesity programs. © 2016 The Author(s) Published by S. Karger GmbH, Freiburg.

John Cairns Jr.

2004-05-01

Full Text Available Society depends heavily on its major universities and independent research organisations for new ideas. Arguable, sustainable use of the planet will require conceptual paradigms unprecedented in human history. Educational systems, especially major universities and research organisations, must produce students in all phases of the educational continuum who are capable of transdisciplinary activities. A much larger group of such students will be required to implement these new undertakings. Until the perception of the need for transdisciplinary education becomes widespread, nothing significant is likely to happen. One major obstacle is the lack of employment for transdisciplinary individuals. A commitment to sustainable use of the planet will provide employment and make better use of increasingly scarce resources.

Sustainable agriculture should be able to meet various social goals and objectives so that it can be maintained for an indefinite period without significant negative impacts on environment and natural resources. A wide variety of agricultural activities are running in Malaysia. Maintaining high quality of agricultural products with lower environmental impacts through a sustainable economic viability and life satisfaction of farmers and community are important factors helping to meet sustainable agriculture. Human resources are playing key role in directing the community toward sustainable development. The trend of improving the human development index in Malaysia is highest in the East Asia and the Pacific, high human development countries and the world, since 2000. Precision agriculture is providing strong tools to achieve sustainable agriculture. Different types of sensors, positioning and navigation systems, GIS, software and variable rate technology are well known components of precision agriculture. Drones and robots are promising tools that enabling farmers and managers to collect information or perform particular actions in remote areas or tough conditions. According to a survey, forestry and timber, rubber production and oil palm estates are three main agricultural divisions that precision agriculture may improve the productivity in respect to area of cropland/worker. Main factors affecting the adoption of precision agriculture in Malaysia are: a) Political and legal supports, b) Decision support systems and user interfaces c) Experienced research team works d) National educational policy e) Success in commercialization of precision agriculture system.

Li, Liqun; Pan, Shengsheng; Ni, Binting; Lin, Yuanshao

2014-08-01

Early neovascularization is important for autologous fat transplant survival. SVF cells are ideal seed cells. Both vascular endothelial growth factor (VEGF) and SVF cells can promote neovascularization. However, the half-life (about 50 min) of VEGF is too short to sustain an adequate local concentration. We have investigated whether VEGF-polylactic acid (PLA) nano-sustained release microspheres plus SVF cells can improve neovascularization and survival of transplanted fat tissues. SVF cells were harvested and constructed VEGF-PLA nano-sustained release microspheres in vitro. Human fat tissues was mixed with SVF cells plus VEGF-PLA, SVF cells alone or Dulbecco's modified Eagle's medium as the control. These three mixtures were injected into random sites in 18 nude mice. Two months later, the transplants were weighed and examined histologically; and capillaries were counted to quantify neovascularization. Hematoxylin-eosin (HE) and anti-VEGF stains were applied to reveal cell infiltration. The mean wet weight of fat in the SVF plus VEGF-PLA, SVF alone, and control transplants were 0.18 ± 0.013 g, 0.16 ± 0.015 g, and 0.071 ± 0.12 g, respectively; the differences between groups were statistically significant. More vessels were present in the SVF plus VEGF-PLA transplants than in the other two types. Transplants mixed with SVF cells also had an acceptable density of capillaries. Histological analysis revealed that both the SVF plus VEGF-PLA and SVF alone transplants, but not the control transplants, were composed of adipose tissue, and had less fat necrosis and less fibrosis than control specimens. SVF plus VEGF-PLA transplants had significantly greater capillary density and VEGF expression than the other two transplant groups. Thus transplanted fat tissue survival and quality can be enhanced by the addition of VEGF-PLA nano-sustained release microspheres plus SVF cells. © 2014 International Federation for Cell Biology.

Terrorism, racism, speciesism, and sustainable use of the planet

Directory of Open Access Journals (Sweden)

John Cairns Jr.

2002-12-01

Full Text Available The 11 September 2001 attacks on the World Trade Center in New York City and the US Pentagon in Washington, DC have seized our attention and undermined our sense of security. These terrorist actions showed a contempt for other persons and their beliefs and practices. They are extreme demonstrations of a feeling of superiority which ignores the inherent worth of life by killing or wounding some and depriving others of resources that improve their quality of life. In this respect, terrorism is similar to racism and speciesism in that all are expressions of feelings of superiority over other life forms and that all are incompatible with sustainable use of the planet. It is proposed that both terrorism and racism have their genesis in speciesism. Sustainability requires a mutualistic relationship between humans and the millions of other species that collectively constitute the planet's ecological life support system. It further requires enhancement and protection of natural capital, as well as the enhancement and protection of the technological and economic life support systems that depend upon natural capital. Both terrorism and racism endanger the fair and equitable allocation of resources and the quality of human life of present and future generations. This is probably both the cause and effect of resource allocations. However, to achieve sustainable use of the planet, humans must acknowledge the inherent worth of other life forms. There is no guarantee that abolishing terrorism, racism, and speciesism will enable human society to acheive sustainable use of the planet; however, it is difficult to envision achieving sustainability if they persist.

Urban Landscapes and Sustainable Cities

Erik Andersson

2006-06-01

Full Text Available Ecological research targeting sustainable urban landscapes needs to include findings and methods from many lines of ecological research, such as the link between biodiversity and ecosystem function, the role of humans in ecosystems, landscape connectivity, and resilience. This paper reviews and highlights the importance of these issues for sustainable use of ecosystem services, which is argued to be one aspect of sustainable cities. The paper stresses the need to include social and economic factors when analyzing urban landscapes. Spatially explicit data can be used to assess the roles different green areas have in providing people with ecosystem services, and whether people actually have access to the services. Such data can also be used to assess connectivity and heterogeneity, both argued to be central for continuous, long-term provision of these services, and to determine the role urban form has for sustainability.

Heritage contribution in sustainable city

The concept of sustainability has been an integral part of development work since the late 1970s. Sustainability is no longer a buzzword but a reality that must be addressed by cities all over the world. Increasing empirical evidence indicates that city sustainability is not just related to technical issues, such as carbon emissions, energy consumption and waste management, or on the economic aspects of urban regeneration and growth, but also it covers social well-being of different groups living within increasingly cosmopolitan towns and cities. Heritage is seen as a major component of quality of life, features that give a city its unique character and provide the sense of belonging that lies at the core of cultural identity. In other words, heritage by providing important social and psychological benefits enrich human life with meanings and emotions, and raise quality of life as a key component of sustainability. The purpose of this paper, therefore, is to examine the role that built cultural heritage can play within sustainable urban development.

Full Text Available Humans are exposed to pesticides as a consequence of their application in farming or their persistence in a variety of media, including food, water, air, soil, plants, animals, and smoke. The interaction of pesticides with environmental factors may result in the alteration of their physicochemical properties. Square wave cathodic stripping voltammetry (SW-CSV, a technique that simulates electrodynamically the cellular membrane, is used to investigate whether the presence of potassium nitrate (KNO3 in the culture medium interferes with the genotoxic behavior of imidacloprid. The cytokinesis block micronuclei (CBMN method is used to evaluate imidacloprid's genotoxicity in the absence or presence of KNO3 in the culture medium and, as a consequence, its adsorption by lymphocytes. Comparing micronuclei (MN frequencies in control and imidacloprid-treated blood cell cultures, statistically significant differences were not detected. KNO3 did not induce MN frequencies compared to control. Statistically significant differences in MN frequencies were observed when blood cell cultures were treated with imidacloprid in the presence of increasing concentrations of KNO3. SW-CSV revealed that by increasing KNO3 molarity, imidacloprid's concentration in the culture medium decreased in parallel. This finding indicates that imidacloprid is adsorbed by cellular membranes. The present study suggests a novel role of a harmless environmental factor, such as KNO3, on the genotoxic behavior of a pesticide, such as imidacloprid. KNO3 rendered imidacloprid permeable to lymphocytes, resulting in elevated MN frequencies.

The aim of the present study was to evaluate the role of HPV in laryngeal squamous cell carcinoma and correlate it with patients' clinicopathological data. In total, 78 laryngeal squamous cell carcinoma patients enrolled in this study. The presence of genotype-specific HPV DNA was evaluated using Genotyping Assay in formalin-fixed paraffin-embedded tissue which was diagnosed between 2005 and 2015. All samples were also evaluated for p16 immunohistochemical staining. HPV DNA and p16 status were assessed in terms of location, smoking, alcohol consumption, lymph node status, tumor stage, overall survival, disease-free survival, perineural invasion, and vascular invasion retrospectively. Five test samples were excluded from the study due to inadequate deoxyribonucleic acid purity. HPV DNA was detected in 19 of 73 (26.02%) in patients with laryngeal squamous cell carcinoma. Human papilloma virus genotyping revealed double human papilloma virus in one case (types 16 and 59) and HPV 16 in the remaining cases. Although HPV-positive cases showed slightly better 3 years survival than HPV-negative ones, this finding was not statistically significant (overall survival p = 0.417, HPV positive: 92.3%, HPV negative: 81.4%, and disease-free survival p = 0.526, HPV positive: 93.8%, HPV negative: 80.9%). The presence of HPV DNA was not significantly associated with any clinicopathological features (p > 0.05). Among 73 patients, only 4 had an immunohistochemical staining of p16 and these patients were also HPV DNA 16 positive. Although our study results revealed a slightly better survival in patients with HPV DNA positivity for HPV 16 compared to the negative ones, the difference was not statistically significant. However, an increasing rate in especially high-risk-type HPV-16 prevalence in laryngeal squamous cell carcinoma by RT-PCR method was observed compared to our previous study. Although the presence of HPV in laryngeal SCCs seems to be associated with slightly better

Human papilloma virus (HPV) accounts for the most common cause of all virus-associated human cancers. Here, we describe the first graphic user interface (GUI)-based automated tool 'HPVDetector', for non-computational biologists, exclusively for detection and annotation of the HPV genome based on next-generation sequencing data sets. We developed a custom-made reference genome that comprises of human chromosomes along with annotated genome of 143 HPV types as pseudochromosomes. The tool runs on a dual mode as defined by the user: a 'quick mode' to identify presence of HPV types and an 'integration mode' to determine genomic location for the site of integration. The input data can be a paired-end whole-exome, whole-genome or whole-transcriptome data set. The HPVDetector is available in public domain for download: http://www.actrec.gov.in/pi-webpages/AmitDutt/HPVdetector/HPVDetector.html. On the basis of our evaluation of 116 whole-exome, 23 whole-transcriptome and 2 whole-genome data, we were able to identify presence of HPV in 20 exomes and 4 transcriptomes of cervical and head and neck cancer tumour samples. Using the inbuilt annotation module of HPVDetector, we found predominant integration of viral gene E7, a known oncogene, at known 17q21, 3q27, 7q35, Xq28 and novel sites of integration in the human genome. Furthermore, co-infection with high-risk HPVs such as 16 and 31 were found to be mutually exclusive compared with low-risk HPV71. HPVDetector is a simple yet precise and robust tool for detecting HPV from tumour samples using variety of next-generation sequencing platforms including whole genome, whole exome and transcriptome. Two different modes (quick detection and integration mode) along with a GUI widen the usability of HPVDetector for biologists and clinicians with minimal computational knowledge.

Water reuse has become increasingly important for sustainable water management. Currently, its application is primarily constrained by the potential health risks. Presently there is limited knowledge regarding the presence and fate of opportunistic pathogens along reuse water distribution pipelines. In this study opportunistic human pathogens Legionella spp., L. pneumophila and Mycobacterium avium complex were detected using real-time polymerase chain reaction along two South Australian reuse water distribution pipelines at maximum concentrations of 10⁵, 10³ and 10⁵ copies/mL, respectively. During the summer period of sampling the concentration of all three organisms significantly increased (P < 0.05) along the pipeline, suggesting multiplication and hence viability. No seasonality in the decrease in chlorine residual along the pipelines was observed. This suggests that the combination of reduced chlorine residual and increased water temperature promoted the presence of these opportunistic pathogens.

Sustainability, glocal development and planetary citizenship. References for a Pedagogy towards Sustainable Development

Directory of Open Access Journals (Sweden)

M.ª Ángeles MURGA-MENOYO

2017-06-01

Full Text Available Sustainability approaches advise adopting a glocal development model that links local possibilities and practices to global needs and constraints. The complexity of this phenomenon, taken to the political plane, leads to a model of planetary citizenship where humanity’s commitment to nature and the necessary social equity amongst human beings are emphasized. This has clear implications for pedagogy, which this paper aims to highlight. This work starts from the sustainable development scenarios and concludes with a proposal of a planetary citizenship rooted locally. Glocality and planetary citizenship, a concept close to that of cosmopolitan citizenship –once stripped of its anthropocentric connotations–, both lead to significant missions of education in this framework: the formation of a holistic worldview, based on a complex-system thinking, and building a planetary citizenship. In both cases, the consideration of the human as an eco-dependent being, attributes nature an essential position in the educational processes.

In a research project about work-related issues and corporate sustainability conducted in Brazil, the goal was to better understand how work-related issues were addressed in the corporate context. Particularly, there are some specific initiatives that serve as guides to organizational decisions, which make their performance indicators for the context of corporate sustainability. 1) To explore the presence of work-related issues and their origins in corporate sustainability approach, analyzing a) corporate disclosures; b) sustainability guidelines that are identified as relevant in corporate disclosures; c) documents that are related to sustainable development and also identified as key-documents for these guidelines and initiatives. 2) To present the activity-centered ergonomics and psychodynamics of work contributions to work-related issues in a corporate sustainability approach. An exploratory study based on multiple sources of evidence that were performed from 2012 to 2013, including interviews with companies that engaged in corporate sustainability and document analysis using the content analysis approach. Work-related issues have been presented since the earliest sustainable development documents. It is feasible to construct an empirical framework for work-related issues and corporate sustainability approaches. 1) Although some authors argue that corporate sustainability has its roots based only on the environmental dimension, there is strong empirical evidence showing that social dimension aspects such as work-related issues have been present since the beginning. 2) Some indicators should be redesigned to more precisely translate the reality of some workplaces, particularly those indicators related to organizational design and mental health.

Endothelium forms an important target for drug and/or gene therapy since endothelial cells play critical roles in angiogenesis and vascular functions and are associated with various pathophysiological conditions. RNA mediated gene silencing presents a new therapeutic approach to overcome many such diseases, but the major challenge of such an approach is to ensure minimal toxicity and effective transfection efficiency of short hairpin RNA (shRNA) to primary endothelial cells. In the present study, we formulated shAnnexin A2 loaded poly(D,L-lactide-co-glycolide) (PLGA) nanoparticles which produced intracellular small interfering RNA (siRNA) against Annexin A2 and brought about the downregulation of Annexin A2. The per cent encapsulation of the plasmid within the nanoparticle was found to be 57.65%. We compared our nanoparticle based transfections with Lipofectamine mediated transfection, and our studies show that nanoparticle based transfection efficiency is very high ({approx}97%) and is more sustained compared to conventional Lipofectamine mediated transfections in primary retinal microvascular endothelial cells and human cancer cell lines. Our findings also show that the shAnnexin A2 loaded PLGA nanoparticles had minimal toxicity with almost 95% of cells being viable 24 h post-transfection while Lipofectamine based transfections resulted in only 30% viable cells. Therefore, PLGA nanoparticle based transfection may be used for efficient siRNA transfection to human primary endothelial and cancer cells. This may serve as a potential adjuvant treatment option for diseases such as diabetic retinopathy, retinopathy of prematurity and age related macular degeneration besides various cancers.

Full Text Available Organizational sustainability (OS has been guiding the decision-making process of managers in order to generate competitive advantage. This paper aims to identify the sustainable practices performed by large corporations in the implementation of OS. Reports with actions performed by large organizations and their reach in the three pillars of sustainability—environmental, economic, and social dimensions—are disclosed to their main stakeholders, based on short, medium and long-term sustainable goals. These reports often reflect the progress of OS or the progress made toward them. However, few studies investigate the sustainable practices adopted by firms and their reproducibility. A search was performed in reports selected from the firms listed by the Corporate Sustainability Index (CSI from 2012–2016, belonging to the Brazilian stock market in services sector of the economy and employed the Global Reporting Initiative (GRI methodology. The results showed the strategic planning involving infrastructure, environment, human resources, product innovation, organizational management and deadline setting acted as the baseline for the implementation of the practices found. The findings will guide the managers´ decisions in the development of their strategic planning, based on practical and objective results.

2014-01-01

In recent years, sustainability has represented one of the most important policy goals explored in the environmental Kuznets curve (EKC) literature. But related hypotheses, performance measures and results continue to present a challenge. The present paper contributes to this ongoing literature by studying two different EKC specifications for 10 Middle East and North African (MENA) countries over the period 1990–2010 using panel data methods. For the first specification, namely EKC, we show that there is an inverted U-shape relationship between environmental degradation and income; while for the second specification, namely modified EKC (MEKC), we show that there is an inverted U-shape relationship between sustainability and human development (HD). The relationships are shaped by other factors such as energy, trade, manufacture added value and the role of law. More interestingly, findings from the estimation show that EKC hypothesis, HD and sustainability are crucial to build effective environmental policies. - Highlights: • Environmental Kuznets curve (EKC) and modified EKC models are examined for 10 MENA countries. • We attempt to include energy, trade, human development and sustainability in our approach. • The inverted U-shape relationship is verified for two models. • Human development positively affects the pollution and sustainability level

Ethics and sustainability

It could be said that the concept of sustainability is based on ethic postulates, because it claims to bear in mind the set of necessities of future generations as a control variable for human development models and for consumption patterns. Ethics, in its own, mainly in the spinozist line of thinking, is a philosophical proposal directed to empowering the operations of expression of the beings (not only of the human being). This ethics outlines multiple developments and conceive future generations not as undifferentiated, passive and impotent collectives, but as active and joyful communities, who are sensitive to the possibilities of their own devenir

COMPANION ANIMALS SYMPOSIUM: Sustainable Ecosystems: Domestic cats and their effect on wildlife populations.

Science.gov (United States)

Kitts-Morgan, S E

2015-03-01

Domestic cats are estimated to kill billions of small mammals and birds each year. In certain areas of the world, it is not uncommon for either feral or free-ranging cats to have high population densities, creating concern regarding their level of hunting. Many cats are considered to be subsidized predators, as they receive care and food from humans. Arguments abound regarding the presence of cats in the habitats of native small mammals and birds and whether or not local ecosystems can sustain this predator-prey relationship. The effects of cats on native wildlife can depend on several factors, including cat classification (feral vs. free ranging vs. indoor-outdoor), geographical location (islands vs. mainland), and type of habitat (rural vs. suburban vs. urban). Feral and free-ranging cats may have a greater impact on native species on islands because habitat is severely limited. Continued urbanization and development of rural areas also creates fragmented habitats, and native species may struggle to survive with the added pressure of hunting by domestic cats. Additionally, cats in rural areas are frequently fed by humans, which can support high population densities and intensify pressure on native species. Species targeted by cats may also vary based on prey availability in different areas, but small mammals are generally preferred over birds, reptiles, or invertebrates. Domestic cats certainly have the potential to roam and hunt in very large areas inhabited by native species and loss of biodiversity is a major concern. Therefore, it is possible that ecosystems may not be able to sustain hunting by domestic cats. Because this predator-prey relationship is probably not sustainable, it is necessary to responsibly manage outdoor domestic cats.

Sustainable Sizing.

Robinette, Kathleen M; Veitch, Daisy

2016-08-01

To provide a review of sustainable sizing practices that reduce waste, increase sales, and simultaneously produce safer, better fitting, accommodating products. Sustainable sizing involves a set of methods good for both the environment (sustainable environment) and business (sustainable business). Sustainable sizing methods reduce (1) materials used, (2) the number of sizes or adjustments, and (3) the amount of product unsold or marked down for sale. This reduces waste and cost. The methods can also increase sales by fitting more people in the target market and produce happier, loyal customers with better fitting products. This is a mini-review of methods that result in more sustainable sizing practices. It also reviews and contrasts current statistical and modeling practices that lead to poor fit and sizing. Fit-mapping and the use of cases are two excellent methods suited for creating sustainable sizing, when real people (vs. virtual people) are used. These methods are described and reviewed. Evidence presented supports the view that virtual fitting with simulated people and products is not yet effective. Fit-mapping and cases with real people and actual products result in good design and products that are fit for person, fit for purpose, with good accommodation and comfortable, optimized sizing. While virtual models have been shown to be ineffective for predicting or representing fit, there is an opportunity to improve them by adding fit-mapping data to the models. This will require saving fit data, product data, anthropometry, and demographics in a standardized manner. For this success to extend to the wider design community, the development of a standardized method of data collection for fit-mapping with a globally shared fit-map database is needed. It will enable the world community to build knowledge of fit and accommodation and generate effective virtual fitting for the future. A standardized method of data collection that tests products' fit methodically

Present paper deals with Radiation Environment Assessment, Measurement and its Impact on Health, its meaning and in particular with sustainable development perspective. Health and Environment appears to be different subjects and concepts, but in reality they are interrelated and interdependent. One cannot exist without the other. For good health hygienic environment is a sine qua non. Article 3 of Universal Declaration of Human Right 1948 incorporates the right to life. It has been interpreted by the international court that the word life does not means simply to live but it means to live with dignity and in well and pollution and radiation free environment which is a gift of nature on this universe. There is no doubt about the nuclear revolution that has taken place and has made life of human beings worth living on this earth with comfort. It is growing development of the nation. But in the process the development that has been done at the cost of human life, public health and environment which will prove fatal in the long run. So there is a need for Sustainable Development of the human and environment of the world. Precisely and concisely, the sustainable development is a process that meets the needs of the present without compromising ability of future generations to meet their own needs. A hygienic and redaction free environment will ensure the better Health of the people. Environment and nuclear power plant can coexist. The harmonization of the two needs has led to the concept of Radiation Environment Assessment and sustainable development, so much so that it has become the most significant and focal point of environmental legislation relating to the same. Sustainable development, simply put, is a process in which development can be sustained over generations effects of radiation on humans and on the environment. Finally, this paper deals with the impact of radiation on environment and the need of sustainable development for achieving a better human. (author)

Full Text Available Sustainability as a multifaceted and holistic concept is analyzed. Sustainability involves human relationship with elements such as natural environment, economy, power, governance, education and technology with the ultimate purpose of carrying forward an ever-advancing civilization. The Fixed Bed Nuclear Reactor (FBNR is an innovative, small, simple in design, inherently safe, non-proliferating, and environmentally friendly concept that its deployment can generate energy in a sustainable manner contributing to the prosperity of humanity. The development of FBNR will provide electricity as well as desalinated water through a simple but advanced technology for the developing, as well as developed countries. FBNR is environmentally friendly due to its inherent safety and the convenience of using its spent fuel as the source of radiation for irradiation purposes in agriculture, industry, and medicine. Politically, if a ping pong game brought peace between China and USA, a program of development of FBNR supported by the peace loving international community can become a more mature means to bring peace among certain apparently hostile nations who crave sustainable energy, desalinated water and simple advanced technology.

Resource over-exploitation and resource depletion have received increasing attentions, especially for industrial regions. In this paper an innovative method that combines emergy analysis and an IPAT (Human Impact Population Affluence Technology) equation is developed in order to create an integrated framework for uncovering the driving forces on resource consumption in one industrial region. Liaoning province, one of the old heavy industrial bases in China, is selected as the case study region. The main results show that total emergy of Liaoning province increased from 9.25E + 23 sej in 2002 to 1.92E + 24 sej in 2012, with 165% growth on non-renewable emergy and 250% growth on imported emergy. Regional emergy/RMB ratio was higher than other developed regions and the average value of China, indicating that this province consumed more local free non-renewable resources to support its own development. The lower ESI (emergy sustainability index) indicates that Liaoning province's sustainability is still weak and far away from sustainable development. IPAT analysis further identifies that rapid economic growth was the main driving force to increase its total emergy use, while technology innovation offset the increase of total emergy use. Policy insights suggest that industrial regions should improve their energy efficiency and optimize their economic and energy structure by applying economic instruments and capacity building efforts. - Highlights: • Emergy analysis and IPAT are combined to evaluate the sustainability of Liaoning. • Total emergy of Liaoning increased from 2002 to 2011 and then decreased in 2012. • Economic scale is the key driving force to induce higher emergy consumption. • Valuable policy insights are proposed in order to promote sustainable development.

Full Text Available This study aims to compare United Nations 2030 Agenda for Sustainable Development with Millennium Declaration in terms of their security conceptualizations to explore changes in security thinking and policy components (goals, targets, principles, priorities etc. over time. In doing so, it is envisaged that United Nations’ expectations from member states regarding their national security policies and organizations could be revealed. Security thinking has changed since late 1980’s with the introduction of sustainable development approach by the United Nations. This shift in security thinking encompasses human security and security-development nexus. Holding all member states responsible, Millennium Declaration and 2030 Agenda for Sustainable Development constitute the primary and the most recent outcome documents of United Nations’ sustainable development policy. Both documents have security components. This enables extracting security elements and comparing them with an analytical manner. Consequently, findings are compared and discussed in terms of public policy and organization at national level.

The concept of remote presence in telemanipulation is presented. A conceptual design of a prototype teleoperator system incorporating remote presence is described. The design is presented in functional terms, sensor, display, and control subsystem. An intermediate environment, in which the human operator is made to feel present, is explicated. The intermediate environment differs from the task environment due to the quantity and type of information presented to an operator and due to scaling factors protecting the operator from the hazards of the task environment. Potential benefits of remote presence systems, both for manipulation and for the study of human cognition and preception are discussed.

The WHS Designation—A Factor of Sustainable Tourism Growth for Romanian Rural Areas?

Directory of Open Access Journals (Sweden)

Corneliu Iațu

2018-02-01

Full Text Available The presence of World Heritage Sites has been frequently used as a mean of tourism promotion and increased attractiveness. However, previous studies showed contradictory results regarding the territorial impact of World Heritage Sites, and very few researchers discussed their impact in Eastern Europe. This paper examines how the presence of World Heritage Sites in rural localities influenced the tourism growth and sustainable development in Romania after 2000. Independent Sample t-test was used to analyse the evolution of tourism and sustainable development indicators between 2001 and 2016. The results suggest an absence of a positive effect induced by World Heritage Sites in rural areas. It seems that, by itself, the brand has not enough power to sustain tourist attractiveness if it is not endorsed by national, regional, and local initiatives. These findings lead a discussion about how certain sites managed to induce a sustained tourism growth while others failed to do so.

What is sustainability and what influences it?

Schock, R.N.

1997-06-04

I was asked to speak on the subject of ``What do we mean by sustainability and what factors have the most impact on it?`` I am afraid I must admit that if there is a generally accepted definition of sustainability, at least as applied to mankind and terrestrial systems, then I am not aware of it. But I expect you know that, or you would not be having this session. The subject of sustainability is one that interests us all. In fact, I think that it fascinates us all because the concept is one to which we can intimately relate. Sustainability implies eternal life; and throughout history, humankind has sought, sometimes secretly, sometimes openly, eternal life, if not for ourselves at least for our progeny. What I will try to do is (1) briefly discuss some of what has been said about this topic, (2) propose a definition that I believe is workable, and point out some of the issues that derive from it, and then (3) suggest what I think we can all do to ensure the sustainability of the planet. I confess to you at the outset that I am an optimist on this subject, and a technological optimist at that. By that I mean that I believe that humans and technology are inextricably linked and that technology provides one of the great keys to helping human beings achieve their goals. I also believe that sustainability is an achievable goal and that it is not a concept to be feared, either intrinsically or economically.

Full Text Available The presence of yeasts and staphylococci in the oral cavity is important because they can act as supplementary microbiota and in certain situations can cause oral or systemic diseases. The aim of this work was to study the prevalence of Candida spp. and Staphylococcus spp. in the human oral cavity. Oral rinses were collected from sixty-eight individuals according to the technique described by Samaranayake and MacFarlane and then cultured on Sabouraud medium supplemented with chloramphenicol and Baird-Parker agar. After the incubation period, the microorganisms were isolated and identified through biochemical tests. The data obtained were statistically analysed by ANOVA. Candida spp. were isolated from 61.76% of the examined individuals and C. albicans was the more frequently isolated specie. Staphylococcus spp. were isolated from 95.60% of the individuals and 41 strains were coagulase negative (63%. Among the coagulase positive strains, nine were S. aureus, 11 S. hyicus and 4 S. schleiferi subspecie coagulans. No correlation was observed between the counts (cfu of the isolated Candida spp. and Staphylococcus spp.

Sunlight-induced inactivation of human Wa and porcine OSU rotaviruses in the presence of exogenous photosensitizers

KAUST Repository

Romero-Maraccini, Ofelia C.

2013-10-01

Human rotavirus Wa and porcine rotavirus OSU solutions were irradiated with simulated solar UV and visible light in the presence of different photosensitizers dissolved in buffered solutions. For human rotavirus, the exogenous effects were greater than the endogenous effects under irradiation with full spectrum and UVA and visible light at 25 C. For porcine rotavirus, the exogenous effects with UVA and visible light irradiation were only observed at high temperatures, >40 C. The results from dark experiments conducted at different temperatures suggest that porcine rotavirus has higher thermostability than human rotavirus. Concentrations of 3′-MAP excited triplet states of 1.8 fM and above resulted in significant human rotavirus inactivation. The measured excited triplet state concentrations of ≤0.45 fM produced by UVA and visible light irradiation of natural dissolved organic matter solutions were likely not directly responsible for rotavirus inactivation. Instead, the linear correlation for human rotavirus inactivation rate constant (kobs) with the phenol degradation rate constant (kexp) found in both 1 mM NaHCO3 and 1 mM phosphate-buffered solutions suggested that OH radical was a major reactive species for the exogenous inactivation of rotaviruses. Linear correlations between rotavirus kobs and specific UV254 nm absorbance of two river-dissolved organic matter and two effluent organic matter isolates indicated that organic matter aromaticity may help predict formation of radicals responsible for rotavirus inactivation. The results from this study also suggested that the differences in rotavirus strains should be considered when predicting solar inactivation of rotavirus in sunlit surface waters. © 2013 American Chemical Society.

The path to presence in performance through movement, physiological response, and mood

Full Text Available Presence may occur when actors are alert and relaxed in performance. A positive mood is associated with physical activity, but little is known about how movement qualities affect mood and vital signs of actors. This study examined the effects of vibratory, pendular, abrupt, and sustained movement qualities on the Brief Mood Introspection Scale, and physiology. Undergraduate theatre (n = 25 and non-theatre majors (n = 24 engaged in protocols of four movement qualities: vibratory, pendular, abrupt and sustained. Mood and heart rate, blood pressure, respiration rate, and temperature were measured before and after four different movement protocols. The hypothesis that the sequence of vibratory, pendular, sustained, and abrupt increased the alert, relaxed state of Presence and Arousal was rejected. It was found that systolic blood pressure increased in men across protocols. A significant interaction was found between the participants’ major and “Tired.” Because Tired and Arousal indicate mental and/or physical energy, a relationship between MAJOR and “Tired,” combined with significant correlation between subjects and major, suggests that the protocols resulted in fatigue. Half of the mood variance is explained by the factor “major.” These two significant findings suggest a relationship between mood and major as well as blood pressure and gender.

We are working on ongoing challenges, such as reducing the energy required to meet our research mission and promoting conservation among our employees.

Experimental Standards in Sustainability Transitions

DEFF Research Database (Denmark)

Hale, Lara Anne

In this thesis I address how experimental standards are used in the new governance paradigm to further sustainability transitions. Focusing on the case of the Active House standard in the building sector, I investigate experimental standards in three research papers examining the following dynamics......: (1) the relationship between commensuration and legitimacy in the formulation and diffusion of a standard’s specifications; (2) the role of awareness in standardizing green default rules to establish sustainable consumption in buildings; and (3) the significance of focus on humans in the development...... of technological standards for sustainable building. Launching from a critical realist social ontology, I collected ethnographic data on the Active House Alliance, its cofounder VELUX, and three of their demonstration building projects in Austria, Germany, and Belgium over the course of three years from 2013...

Full Text Available Today sustainable development is a widely used term, which has been increasingly influential in recent years. Debates about sustainability no longer consider sustainability solely as an environmental concern, but also incorporate economic and social dimensions. However, while a social and economic dimensions of sustainable development are widely discussed, environmental degradation becomes more and more crucial each year and is likely to reduce human well-being all across the world within the next few decades. The purpose of the paper is to analyse ecological ‘pillar’ of sustainable development, its historical background, main steps towards implementation of ‘new global environmental rules for society. Methodology. The paper is based on statistical information from public sources, reports of different international organizations and institutions, which are used to stress and underline main crucial points of research. Results of the survey show, that environmental quality, economic development and social well-being are interdependent and the main aim of international institutions, independent countries, businesses and society is to achieve environmentally sustainable development. Environmental issues make strong impact on modern economy. Responsible global strategy of development provides the whole society with rules, how ‘wise’ technological changes and economic policy can make industrial production processes less polluting and less resource intensive but yet more productive and profitable. Practical implications. Strategy of sustainable development and it’s three basic dimensions have found practical implication in one complex model, which illustrates the level of development of each country – the Human Development Index, which is focusing on three basic dimensions of human development: life expectancy at birth, mean years of schooling and expected years of schooling and gross national income per capita.

Future development needs to be sustainable in all of its dimensions if it is to continue to fully contribute to human welfare. In the achievement of this objective, the manner in which energy is produced and consumed is of crucial importance. In the wake of these insights, first attempts begin to provide concrete options for steps towards sustainability in the energy sector. Two criteria can be identified for developing sustainable development policies. First, such policies need to strike a balance between the three dimensions of sustainable development - economic, environmental and social - acknowledging that all three are intrinsically linked. Second, policies in the energy sector need to reduce exposure to large-scale risks and improve the resilience of the energy system through active risk management and diversification. (authors)

Investigating Environmentally Sustainable Transport Based on DALY weights and SIR Method

2012-09-01

Full Text Available Accessibility is one of the main causes of well-being and growth in contemporary societies. Transportation is the backbone of accessibility systems that lead to the growth of economic and social networks and spatial dispersion of activities. Unfortunately, the adverse effects of transportation have a great impact on the natural and human environment. Since transportation is associated with fossil fuel combustion, it results in emissions of pollutants that cause damage to human health. To save the global eco-system, sustainable development has become an international priority. To deal with the sustainability of transportation systems is an important issue as testified by a growing number of initiatives framed to define and measure sustainability in transportation planning and infrastructure planning as well. The capability of environmental assessment as a sustainability instrument is well known. This study proposes a new approach to rank countries based on environmental sustainability development applying disability adjusted life year (DALY weights for transportation sector emissions. DALY weights consider actual impacts of pollutants on human health. By employing SIR method, a superiority and inferiority ranking method is presented for multiple criteria decision making, the sustainability ranking of a number of European countries is presented. Three various ranking methods extracted from SIR ranking method are discussed and the results and the correlation among them are demonstrated.

The concept and principles of sustainable architectural design for national parks in Serbia

Directory of Open Access Journals (Sweden)

Milošević Predrag

2004-01-01

Full Text Available The paper elaborates the concept of sustainable architectural design that has come to the forefront in the last 20 years, and in the light of the National Park. This concept recognizes that human civilization is an integral part of the natural world and that nature must be preserved and perpetuated if the human community itself is to survive. Sustainable design articulates this idea through developments that exemplify the principles of conservation and encourage the application of those principles in our daily lives. A corollary concept, and one that supports sustainable design, is that of bio-regionalism - the idea that all life is established and maintained on a functional community basis and that all of these distinctive communities (bio-regions have mutually supporting life systems that are generally self-sustaining. The concept of sustainable design holds that future technologies must function primarily within bioregional patterns and scales. They must maintain biological diversity and environmental integrity contribute to the health of air, water, and soils, incorporate design and construction that reflect bio-regional conditions, and reduce the impacts of human use. Sustainable design, sustainable development, design with nature environmentally sensitive design, holistic resource management - regardless of what it's called, "sustainability," the capability of natural and cultural systems being continued over time, is the key. Sustainable design must use an alternative approach to traditional design and the new design approach must recognize the impacts of every design choice on the natural and cultural resources of the local, regional, and global environments. Sustainable park and recreation development will succeed to the degree that it anticipates and manages human experiences. Interpretation provides the best single tool for shaping experiences and sharing values. By providing an awareness of the environment, values are taught that are

Delineating a sustainable future

International Nuclear Information System (INIS)

Brown, Lester R

1996-01-01

The expression Develop Sustainable of wide use today in day is used among national political leaders and among environmentalists. The sustainable economy from the environmental point of view is that that obeys the basic principles or laws of the sustainability; principles so real as those of the aerodynamic one or those of the thermodynamic. If somebody intends, for example, to design an airplane, it will have to be adjusted to the aerodynamic principles and to print to the apparatus a certain stability degree so that it can fly. In the same way, an economic system environmentally sustainable it must respond to the balance principles if it doesn't want to be condemned to the failure. The fundamental laws or sustainability principles are as rigorous as the aerodynamic laws. The society can violate these laws in the short term; but not long term. As well as an airplane can lose height in a brief lapse without falling; the economy can violate the principles of the sustainability in the short term without collapsing. Among of the sustainability principles figure the following: long term; the extinction of species cannot exceed the evolution of the species; the soil erosion cannot exceed the soils formation; the destruction of forests cannot exceed the regeneration of the forests; the emissions of carbon cannot exceed the fixation of carbon; the fishing cannot exceed the regenerative capacity of the banks of fish and, in the human land, the morbidity cannot exceed the mortality. The author also speaks of the disappearance of species, ozone layer, stability of the climate, earth, water fertilizers and alimentary systems among others

The Century Ahead: Searching for Sustainability

2010-08-01

Full Text Available The global future lies before us as a highly uncertain and contested landscape with numerous perils along the way. This study explores possible pathways to sustainability by considering in quantitative detail four contrasting scenarios for the twenty-first century. The analysis reveals vividly the risks of conventional development approaches and the real danger of socio-ecological descent. Nonetheless, the paper underscores that a Great Transition scenario—turning toward a civilization of enhanced human well-being and environmental resilience—remains an option, and identifies a suite of strategic and value changes for getting there. A fundamental shift in the development paradigm is found to be an urgent necessity for assuring a sustainable future and, as well, a hopeful opportunity for creating a world of enriched lives, human amity, and a healthy ecosphere.

Testing for the Best Instrument to Generate Sustainable Food Consumption

Luca Panzone

2011-12-01

Full Text Available  The increase in the level of greenhouse gas (GHG emissions in the atmosphere in the last centuries, and the subsequent increase in temperature, has been a widely studied area in the last few decades. Climate change has become a key item on the political agenda due to concerns regarding the sustainability of current human consumption for future generations. Consumption of food and agricultural goods constitutes an important part of household based GHG emissions, and the relatively low costs associated with environmental improvements make it an interesting area of study to understand behavioural changes. Despite general agreement on the need to curb the amount of GHG emissions worldwide, little evidence exists regarding the best instruments policymakers can employ to stimulate changes toward more sustainable consumption. The present work explores which instruments are most effective in fostering change to more environmentally friendly food consumption. The instruments tested are CO2 labelling, GHG abatement subsidy and product-specific bans. We used a simulated online shopping trip in supermarkets in the Greater London area in the United Kingdom, where respondents shopped in four product categories: cola, milk, meat (chicken and beef, and butter/margarine. Consumer preferences reveal that, in the presence of these instruments, quantity instruments performed better than price incentives and labelling.

2005-01-01

This study was undertaken to investigate whether a physiologically compatible concentration of 7-ketocholesterol had any effect on human vascular smooth muscle cells (HVSMCs). We found that 7-ketocholesterol changed the viability of human aorta smooth muscle cells (HAoSMC) not by cytotoxicity but by activation of tumor necrosis factor-α receptor (TNFR)-mediated death. Whereas TNF-α did not affect the viability in the presence of 7α-hydroxycholesterol or cholesterol, the cytokine induced HAoSMC death in the presence of 7-ketocholesterol as detected by morphology, viability, and fragmentation of chromosomal DNA. The HAoSMC death was inhibited by a neutralizing anti-TNF receptor 1 (TNFR1) antibody and by the caspase inhibitors of z-VAD and z-DEVD. Activations of caspase-8 and -3 were detected from dying HAoSMCs. 7-Ketocholesterol inhibited translocation of the nuclear factor κB (NF-κB) subunits of p65 and p50 from the cytosol into the nucleus, increase of NF-κB activity, and expression of caspase-8 homolog Fas ligand interleukin-1-converting enzyme inhibitory protein by TNF-α. We also found that X-chromosome-linked inhibitor of apoptosis protein was degraded in dying HAoSMC. The present study proposes that 7-ketocholesterol would contribute to the disappearance of HVSMC in the atherosclerotic lesions by enhancing receptor-mediated death. This is the first report demonstrating induction of TNF-α-mediated death by oxysterol in cells

Martin Haigh

2010-11-01

Full Text Available Increasingly, sustainability is conceived as a crisis of the human mind and the key challenge for pro-sustainability education is developing sufficient motivation in learners. The spiritual aspirations of religious communities contain sufficient motivational force, which may be deployed for effective sustainability education. This paper explores the approaches to sustainability and sustainability education of some internationally-oriented Hindu religious movements. These include the rural education initiatives of Gandhian Sarvodaya, which emphasizes non-harming, self-reliance and personal ethics, ISKCON, which emphasizes devotional service, P.R. Sarkar’s Ananda Marg, which emphasizes cooperative enterprise, the Tantric body re-imagined at the social scale, and Swami Vivekananda’s Sri Ramakrishna Order, which emphasizes karma yoga, spiritual development through service to the God in each human. It also describes the British Hindu contribution to the UNDP/ARC’s multi-faith sustainability initiative “Many Heavens, One Earth”; which is the “Bhumi Project” and its two main campaigns, Green Temples and Compassionate Living.

On this basis the substantial potential of communication is determined. A di-verse range of communication’s actions is presented. Communication carries out satisfaction the people’s need in emotional resonance and empathy; penetration into the inner world of Another, co-presence, being «here» and «now» together with Another; integration, unity, feeling part of a whole people and becoming related; finding a certain sense; producing and approving of values, humanization; realiza-tion of the basic human need - to be included in society and culture, i.e., generic quality of sociality which is inherent to man; improvisation, in conjunction with the presence of algorithms in the communication; preventing, overcoming an inferiority of people’s objectivisation, de-objectivisation; counteracting to the massification, standardization, «oversimplification» of consciousness and personality. Thereby this paper shows that communication efficiently overcomes and blocks the most of the challenges/risks, which might lead to instability of the socie-ty’s development in the informational stage of history - the four groups from six groups, which were identified in this article. As a result, the positive influence of communication on the sustainability of modern society in a global scale has been substantiated and proven.

Making sustainability work

International Nuclear Information System (INIS)

Binswanger, Hans Christoph

1998-01-01

Today's economic theory usually neglects the role of nature and environment. To make sustainability work it is, however, essential to (re-)integrate nature into the standard concepts of economics, especially by incorporating natural factors into the production function. It must be acknowledged that economic growth is not (only) the result of technical change but is mainly caused by rising energy-inputs into the economy, and that this is necessarily followed by resource exhaustion and pollution. Therefore, nature must not only be taken into account as a central factor of production but also in the form of environmental quality which is the basis for human quality of life. A numeric example shows that a small, but steady decrease of yearly resource consumption is already apt to redirect the economy on a path of sustainable development

On nuclear power, population and sustainable global civilization

Ishiguro, Yuji

2007-01-01

Humanity is facing a multitude of difficult problems that threaten not only human development but the very continuity of civilization. The fundamental cause is the size of the human population but at present the subject is not discussed in international fora. It is not clear if it is wishfully avoided or if it is not recognized as the fundamental problem. Without limiting fertility and population globally, there will be no future for civilization as we know it and there will be no need for nuclear power as a source of energy. Instead, nuclear power will be the principal agent of the end. The nuclear community is in a position to point out the problem and propose a solution. Principles of sustainability and a path to a sustainable global civilization are shown. (author)

Prosociality and proenvironmentalism as components of sustainable behavior: toward an integrated approach to sustainability education

Directory of Open Access Journals (Sweden)

Alexander Neaman

2015-02-01

Full Text Available The concept of sustainable development includes three interdependent and mutually reinforcing pillars: economic development, social development and environmental protection [1]. Below, we provide arguments that proenvironmentalism and prosociality are components of a broader behavior, named “sustainable behavior”. We thus suggest that traditional emphasis of environmental education on protecting and/or preserving the environment may be reinforced with prosocial education. Such a combined educational approach can promote sustainable behavior, contributing to multi- and inter-disciplinary efforts to create an ecologically, socially and perhaps even economically sustainable society. Proenvironmental behavior is defined as actions which contribute towards environmental preservation and/or conservation [2]. In turn, prosocial behavior is defined as voluntary behavior intended to benefit others or promote harmonious relationship with others [3], [4]. Previous studies demonstrate correlations between proenvironmental and prosocial behavior [5], [7]. For example, Joireman et al. [8] found an association between prosociality and the use of public transport, which has a lower impact on the environment, in comparison to the use of individual motorized transport. Furthermore, [5] and [6] empirically demonstrated that prosociality and proenvironmentalism are components of a broader behavior, which they called “sustainable behavior” since it includes actions aimed at protecting both the natural and the human (social environments. With regards to the environmental aspects of sustainability, some authors suggest that “environmental problems” are actually problems of human behavior [9]. The first definition of environmental education [10] emphasized the importance of educating the general public about taking action to solve environmental problems. Based on the in-depth analysis of [11], the main emphasis of environmental education is limited to the

Sustainable Cities and the Contribution of Historical Urban Green Spaces: A Case Study of Historical Persian Gardens

Directory of Open Access Journals (Sweden)

Raheleh Rostami

2015-09-01

Full Text Available Growing populations and rapid worldwide urbanization are recognized as constituting one of the most complex processes in the world and have raised concerns about the sustainability of cities. Sustainable development, a widely accepted strategic framework in city planning, singles out urban green spaces as a primary solution for addressing these issues. Growing empirical evidences indicate that the presence of natural areas contributes to a better quality of life in many ways. Urban green spaces serve as places of identity, memory, and belonging; enrich human life with meaning and emotions by providing important social and psychological benefits; and enhance the quality of life of citizens, which is a key component of sustainability. Despite our understanding of the benefits of urban green spaces, little is known about the benefits of historical urban green spaces. To highlight their importance with regard to environmental sustainability and citizens’ well-being, this study analyzes a number of historical Persian gardens that are still actively used by urban residents. The findings suggest that historical Persian gardens could accommodate many social functions and address many of the psychological issues relating to urban dwelling. It has been generally acknowledged that sense of community and place attachment is pivotal to creating sustainable urban environments. Historical gardens as physical components can cohesively weave together many parts of cities of any cities while providing places for public congregation as well as attracting a variety of local economic activities. All these attributes can make historical Persian gardens as a valuable municipal resource and a key ingredient for city’s living sustainability.

Using Four Capitals to Assess Watershed Sustainability

Pérez-Maqueo, Octavio; Martinez, M. Luisa; Vázquez, Gabriela; Equihua, Miguel

2013-03-01

The La Antigua watershed drains into the Gulf of Mexico and can be considered as one of the most important areas in Mexico because of its high productivity, history, and biodiversity, although poverty remains high in the area in spite of these positive attributes. In this study, we performed an integrated assessment of the watershed to recommend a better direction toward a sustainable management in which the four capitals (natural, human, social, and built) are balanced. We contrasted these four capitals in the municipalities of the upper, middle and lower watershed and found that natural capital (natural ecosystems and ecosystem services) was higher in the upper and middle watershed, while human and social capitals (literacy, health, education and income) were generally higher downstream. Overall, Human Development Index was negatively correlated with the percentage of natural ecosystems in the watershed, especially in the upper and lower watershed regions. Our results indicate that natural capital must be fully considered in projections for increasing human development, so that natural resources can be preserved and managed adequately while sustaining intergenerational well-being.

Full Text Available Land use has a great impact on environmental quality, use of resources, state of ecosystems and socio-economic development. Land use can be considered sustainable if the environmental pressures of human activities do not exceed the ecological carrying capacity. A scientific knowledge of the capability of ecosystems to provide resources and absorb waste is a useful and innovative means of supporting territorial planning. This study examines the area of the Province of Bari to estimate the ecosystems’ carrying capacity, and compare it with the current environmental pressures exerted by human activities. The adapted methodology identified the environmentally sustainable level for one province.

Social Sustainability and Its Indicators through a Disability Studies and an Ability Studies Lens

Theresa Rybchinski

2013-11-01

Full Text Available The present journal recently stated in the call for a special issue on social sustainability, “[t]hough sustainable development is said to rest on ‘three pillars’, one of these—social sustainability—has received significantly less attention than its bio-physical environmental and economic counterparts”. The current issue promises to engage the concepts of “development sustainability”, “bridge sustainability” and “maintenance sustainability” and the tensions between these different aspects of social sustainability. The aim of the present study is to identify the visibility of disabled people in the academic social sustainability literature, to ascertain the impact and promises of social sustainability indicators put forward in the same literature and to engage especially with the concepts of “development sustainability”, “bridge sustainability” and “maintenance sustainability” through disability studies and ability studies lenses. We report that disabled people are barely covered in the academic social sustainability literature; of the 5165 academic articles investigated only 26 had content related to disabled people and social sustainability. We also conclude that social sustainability indicators evident in the 1909 academic articles with the phrase “social sustainability” in the abstract mostly focused on products and did not reflect yet the goals outlined in the “development sustainability” aspect of social sustainability proposed by Vallance such as basic needs, building social capital, justice and so on. We posit that if the focus within the social sustainability discourse shifts more toward the social that an active presence of disabled people in this discourse is essential to disabled people. We showcase the utility of an ability studies lens to further the development and application of the “development sustainability”, “bridge sustainability” and “maintenance sustainability�

Towards a Global Sustainable Information Society (GSIS?

2008-07-01

Full Text Available The development, diffusion, and adoption of new ICTs doesn’t automatically result in ecological sustainability, it poses both new opportunities and risks. Embedded into the antagonism between capital and economy it seems like the logical of profitability frequently offsets ecological awareness and hence has negative effects on the realization of positive potentials of ICTs on the environment. Environmental problems are social problems, not technological problems, they are neither caused by science or technology as such, nor can they be solved by science or technology as such. The discourse on sustainable development shows a shift from the view of nature as an enemy that must be controlled to a view that considers nature as an important pre-condition of human existence that must be treated carefully. In the discourse on sustainability there has been a shift from a focus on ecological issues towards the inclusion of broader societal issues. It has now become very common to identify an ecological, an economic, a social, and an institutional dimension of sustainability. One can distinguish four types of sustainability concepts based on where in the nature-society-relationship they locate sustainability: ecological reductionism, social projectionism, dualism, man-nature-dialectic. Both nature and society are self-organizing systems in the sense that they permanently produce themselves. Ecological sustainability means that humans appropriate nature in a way that allows ecological diversity, i.e. the autopoiesis of nature can develop in such a way that nature flourishes, reproduces its subsystems, differentiates itself and produces new qualities, i.e. new ecological life forms and subsystems. Societal sustainability can broadly be defined as a good life for all. A sustainable society encompasses ecological diversity, technological usability, economic wealth, political participation, and cultural wisdom. Ecological sustainability is based on social

To strengthen the likelihood of realizing the post-2015 Sustainable Development Goals (SDGs, particularly with regard to “planet and population” health and well-being , UN and other decision-makers are urged to consider the adoption of an integrated SDG framework that is based on (i a vision of global justice - underpinned by peace, security and basic human rights; (ii the development of interdependent and interconnected strategies for each of the eleven thematic indicators identified in the UN document The World We Want; and (iii the application of guiding principles to measure the impact of SDG strategies in terms of holism, equity, sustainability, ownership, and global obligation. While current discussions on the SDGs are making progress in a number of areas, the need for integration of these around a common global vision and purpose seems especially crucial to avoid MDG shortcomings.

Oxidation of lipoproteins is believed to play a key role in atherogenesis. In this study, low density lipoproteins (LDL) was subjected to oxidation in the presence of either human umbilical vein endothelial cells or with Cu+2 ions and the major oxides formed were identified. While cholesterol-alpha-epoxide (C-alpha EP) was the major product of cholesterol peroxidation in the presence of endothelial cells, cholest-3,5-dien-7-one (CD) predominated in the presence of Cu+2 ion. Both steroids were identified by gas chromatography/mass spectrometry. HDL cholesterol was resistant to oxidation. When tested on human skin fibroblasts in culture C-alpha EP (10 micrograms/ml) caused marked stimulation of 14C-oleate incorporation into cholesterol esters, while CD stimulated cholesterol esterification only mildly. These studies show that a) C-alpha EP is the major peroxidation product of LDL cholesterol moiety in the presence of endothelial cells and b) it causes marked stimulation of cholesterol esterification in cells. C-alpha EP may play a key role in increasing cholesterol esterification noted in atherogenesis.

Sustainable development not only involves relations between the global society ant its resource base, the ecosphere, but also relations within the global society itself. It may useful to think of sustainable development as a process with two phases. The first is transitional and involves a transition to a sustainable situation in several essential respects: population; use of natural systems, in particular atmosphere, water, productive land; supply and use of water, food, energy; international order; democracy and human development. The second phase then involves continued development within the restrictions set by the sustainable requirements

Long term management of former chemical production facilities can be a costly and time consuming element of site closure, however, implementation of creative measures to introduce sustainability and reduce the need for onsite presence can be successfully incorporated into the site closure process. A case study demonstrating this involves a facility located in Sarnia, Ontario, which was an active multi chemical production facility from the 1940s, until it was decommissioned and sold between 2005 and 2010. The facility consisted of 322 acres of production areas. Several elements which allowed for reduced onsite presence and lower management costs were incorporated into the site decommissioning plan, including; phased remediation planning, and selection of sustainable components as part of remediation, surface water management, and groundwater management. The sustainability and management modifications were successfully negotiated and approved by the local regulatory agency. Due to the size and complexity of the site, a holistic approach for the facility was needed and included the development of a comprehensive decision matrix. Each remediation alternative incorporated sustainable practices. Ex-situ remediation consisted of excavation of contaminated subsurface medium and consolidation at a 4.7 acre onsite soil treatment area designed specifically for the site closure process. In-situ remediation consisted of injection of amendment into the native soils using hydraulic fracture and injection. When the plant was an active operating facility, groundwater management required active pumping and groundwater treatment through a series of carbon treatment units. Active pumping has been replaced by passive hydraulic control through the use of tree plantations.

Full Text Available Abstract Background Although human papillomavirus (HPV genome has been detected in lung cancer, its prevalence is highly variable around the world. Higher frequencies have been reported in far-east Asian countries, when compared with European countries. The present study analysed the HPV-16 presence in 60 lung carcinomas from the Asian countries China, Pakistan and Papua New Guinea. Results HPV-16 was present in 8/59 (13% samples. According to histological type, HPV-16 was detected in 8/18 (44% squamous cell carcinomas (SQCs, which were mainly from Pakistan; 0/38 (0% adenocarcinomas (ACs, which were mainly from China; and in 0/4 (0% small cell carcinomas (SCLCs. The observed histological difference was statistically significant (p Conclusion These results support the notion that HPV-16 infection is highly associated with SQCs in Pakistan. Our results show a frequent HPV-16 integration in SQCs, although the low viral load casts doubt respect a direct etiological role of HPV in lung carcinomas from Asia. Additional HPV-16 characterization is necessary to establish a direct or indirect etiological role of HPV in this malignancy.

The Tiwi people of northern Australia have managed natural resources continuously for 6000-8000 years. Tiwi management objectives and outcomes may reflect how they gather information about the environment. We qualitatively analyzed Tiwi documents and management techniques to examine the relation between the social and physical environment of decision makers and their decision-making strategies. We hypothesized that principles of bounded rationality, namely, the use of efficient rules to navigate complex decision problems, explain how Tiwi managers use simple decision strategies (i.e., heuristics) to make robust decisions. Tiwi natural resource managers reduced complexity in decision making through a process that gathers incomplete and uncertain information to quickly guide decisions toward effective outcomes. They used management feedback to validate decisions through an information loop that resulted in long-term sustainability of environmental use. We examined the Tiwi decision-making processes relative to management of barramundi (Lates calcarifer) fisheries and contrasted their management with the state government's management of barramundi. Decisions that enhanced the status of individual people and their attainment of aspiration levels resulted in reliable resource availability for Tiwi consumers. Different decision processes adopted by the state for management of barramundi may not secure similarly sustainable outcomes. ©2012 Society for Conservation Biology.

Full Text Available Sustainable transportation and mobility are key components and central to sustainable development. This research aims to reveal the macro-level social, economic, and environmental impacts of alternative vehicle technologies in the U.S. The studied vehicle technologies are conventional gasoline, hybrid, plug-in hybrid with four different all-electric ranges, and full battery electric vehicles (BEV. In total, 19 macro level sustainability indicators are quantified for a scenario in which electric vehicles are charged through the existing U.S. power grid with no additional infrastructure, and an extreme scenario in which electric vehicles are fully charged with solar charging stations. The analysis covers all life cycle phases from the material extraction, processing, manufacturing, and operation phases to the end-of-life phases of vehicles and batteries. Results of this analysis revealed that the manufacturing phase is the most influential phase in terms of socio-economic impacts compared to other life cycle phases, whereas operation phase is the most dominant phase in the terms of environmental impacts and some of the socio-economic impacts such as human health and economic cost of emissions. Electric vehicles have less air pollution cost and human health impacts compared to conventional gasoline vehicles. The economic cost of emissions and human health impact reduction potential can be up to 45% and 35%, respectively, if electric vehicles are charged through solar charging stations. Electric vehicles have potential to generate income for low and medium skilled workers in the U.S. In addition to quantified sustainability indicators, some sustainability metrics were developed to compare relative sustainability performance alternative passenger vehicles. BEV has the lowest greenhouse gas emissions and ecological land footprint per $ of its contribution to the U.S. GDP, and has the lowest ecological footprint per unit of its energy consumption. The

A good understanding of social factors that lead to marine ecological change is important to developing sustainable global fisheries. We used balanced panel models and conducted cross-national time-series analyses (1970-2010) of 122 nations to examine how economic prosperity and population growth affected the sustainability of marine ecosystems. We used catches in economic exclusive zone (EEZ); mean trophic level of fishery landings (MTL); primary production required to sustain catches (expressed as percentage of local primary production [%PPR]); and an index of ecosystem overfishing (i.e., the loss in secondary production index [L index]) as indicators of ecological change in marine ecosystems. The EEZ catch, %PPR, and L index declined gradually after gross domestic product (GDP) per capita reached $15,000, $14,000, and $19,000, respectively, and MTL increased steadily once GDP per capita exceeded $20,000. These relationships suggest that economic growth and biodiversity conservation are compatible goals. However, increasing human populations would degrade marine ecosystems. Specifically, a doubling of human population caused an increase in the %PPR of 17.1% and in the L index of 0.0254 and a decline in the MTL of 0.176. A 1% increase in human population resulted in a 0.744% increase in EEZ catch. These results highlight the importance of considering social and economic factors in developing sustainable fisheries management policy. © 2016 Society for Conservation Biology.

A roadmap for a more sustainable energy strategy is complex, as its development interacts critically with the economic, social, and environmental dimensions of sustainable development. This paper applied an impact matrix method to evaluate the environmental sustainability and to identify the desirable policy objectives of biomass-based energy strategy for the case of Alberta. A matrix with the sustainability domains on one axis and areas of environmental impact on the other was presented to evaluate the nexus effect of policy objectives and bioenergy production. As per to our analysis, economic diversification, technological innovation, and resource conservation came up as the desirable policy objectives of sustainable development for Alberta because they demonstrated environmental benefits in all environmental impact categories, namely climate change, human health, and ecosystem. On the other hand, human health and ecosystem impacts were identified as trade-offs when the policy objectives for sustainability were energy security, job creation, and climate change. Thus, bioenergy can mitigate climate change but may impact human health and ecosystem which then in turn can become issues of concern. Energy strategies may result in shifting of risks from one environmental impact category to another, and from one sustainable domain to another if the technical and policy-related issues are not identified.

HMGA2 Inhibits Apoptosis through Interaction with ATR-CHK1 Signaling Complex in Human Cancer Cells

Full Text Available The non-histone chromatin binding protein high mobility group AT-hook 2 (HMGA2 is expressed in stem cells and many cancer cells, including tumor initiating cells, but not translated in normal human somatic cells. The presence of HMGA2 is correlated with advanced neoplastic disease and poor prognosis for patients. We had previously demonstrated a role of HMGA2 in DNA repair pathways. In the present study, we employed different human tumor cell models with endogenous and exogenous expression of HMGA2 and show that upon DNA damage, the presence of HMGA2 caused an increased and sustained phosphorylation of the ataxia telangiectasia and Rad3-related kinase (ATR and its downstream target checkpoint kinase 1 (CHK1. The presence of activated pCHK1Ser296 coincided with prolonged G2/M block and increased tumor cell survival, which was enhanced further in the presence of HMGA2. Our study, thus, identifies a novel relationship between the ATR-CHK1 DNA damage response pathway and HMGA2, which may support the DNA repair function of HMGA2 in cancer cells. Furthermore, our data provide a rationale for the use of inhibitors to ATR or CHK1 and HMGA2 in the treatment of HMGA2-positive human cancer cells.

The health supply chain is often the weakest link in achieving the health-related Millennium Development Goals and universal health coverage, requiring trained professionals who are often unavailable. In Ethiopia there have been recent developments in the area of health supply chain management. The aim of this study was to explore the current status of the development of human resources in health supply chain management in Ethiopia and to identify important factors affecting this development. A series of face-to-face interviews with key stakeholders was carried out in 2014. The interviews were conducted using a semi-structured interview guide. The interview guide comprised 51 questions. A qualitative analysis of transcripts was made. A total of 25 interviews were conducted. Three themes were identified: General changes: recognition, commitment and resources, Education and training, and Barriers and enablers. Results confirm the development of human resources in health supply chain management in many areas. However, several problems were identified including lack of coordination, partly due to the large number of stakeholders; reported high staff mobility; and a lack of overall strategy regarding the job/career structures necessary for maintaining human resources. Rural areas have a particular set of problems, including in transportation of goods and personnel, attracting and keeping personnel, and in communication and access to information. Ethiopia is on the way to developing a nationwide viable system for health supply chain management. However, there are still challenges. Short-term challenges include the importance of highlighting strategies and programs for human resources in health supply chain management. In the long term, commitments to financial support must be obtained. A strategy is needed for the further development and sustainability of human resources in the health supply chain in Ethiopia.

Partitioning ecosystems for sustainability.

Murray, Martyn G

Decline in the abundance of renewable natural resources (RNRs) coupled with increasing demands of an expanding human population will greatly intensify competition for Earth's natural resources during this century, yet curiously, analytical approaches to the management of productive ecosystems (ecological theory of wildlife harvesting, tragedy of the commons, green economics, and bioeconomics) give only peripheral attention to the driving influence of competition on resource exploitation. Here, I apply resource competition theory (RCT) to the exploitation of RNRs and derive four general policies in support of their sustainable and equitable use: (1) regulate resource extraction technology to avoid damage to the resource base; (2) increase efficiency of resource use and reduce waste at every step in the resource supply chain and distribution network; (3) partition ecosystems with the harvesting niche as the basic organizing principle for sustainable management of natural resources by multiple users; and (4) increase negative feedback between consumer and resource to bring about long-term sustainable use. A simple policy framework demonstrates how RCT integrates with other elements of sustainability science to better manage productive ecosystems. Several problem areas of RNR management are discussed in the light of RCT, including tragedy of the commons, overharvesting, resource collapse, bycatch, single species quotas, and simplification of ecosystems.

Nurse Knowledge Exchange Plus: Human-Centered Implementation for Spread and Sustainability.

Kaiser Permanente implemented a new model of nursing communication at shift change-in the bedside nursing report known as the Nurse Knowledge Exchange (NKE) in 2004-but noted variations in its spread and sustainability across medical centers five years later. The six core elements of NKEplus were as follows: team rounding in the last hour before shift changes, pre-shift patient assignments that limit the number of departing nurses at shift change, unit support for uninterrupted bedside reporting, standardization for report and safety check formats, and collaboration with patients to update in-room care boards. In January 2011 Kaiser Permanente Southern California (KPSC; Pasadena) began implementing NKEplus in 125 nursing units across 14 hospitals, with the use of human-centered design principles: creating shared understanding of the need for change, minimum specifications, and customization by frontline staff. Champion teams on each nursing unit designed and pilot tested unit-specific versions of NKEplus for four to eight weeks. Implementation occurred in waves and proceeded from medical/surgical units to specialty units. Traditional performance improvement strategies of accountability, measurement, and management were also applied. By the end of 2012, 100% of the 64 medical/surgical units and 47 (77.0%) of the 61 specialty units in KPSC medical centers implemented NKEplus-as had all but 1 of the specialty units by May 2013. The mean KPSC score on the NKEplus nursing behavior bundle improved from 65.9% in 2010 to 71.3% in the first quarter of 2014. The mean KPSC Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) score for nurse communication improved from 73.1% in 2010 to 76.4% in the first quarter of 2014 (p < . 001). Human-centered implementation appeared to help spread a new model of nursing handoffs and change the culture of professional nursing practice related to shift change.

The need for sustainable development has been widely recognized and sustainable development has become a hot topic of various disciplines even though the role of ergonomics in it is seldom reported or considered. This study conducts a systematic survey of research publications in the fields of ergonomics and sustainable development over the past two decades (1992-2011), in order to identify their research trends and convergent areas where ergonomics can play an important role in sustainable development. The results show that 'methods and techniques', 'human characteristics', 'work design and organization', 'health and safety' and 'workplace and equipment design' are the top five frequently researched areas in ergonomics. Ergonomics has an opportunity to contribute its knowledge especially to 'industrial and product design', 'architecture', 'health and safety' and 'HCI' (especially for energy reduction issues) categories of sustainable development. Typical methodologies and general guidance on how to contribute the expertise of ergonomist to sustainable development are also discussed. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

Successful implementation of sustainability ideas in ecosystem management requires a basic understanding of the often nonlinear and nonintuitive relationships among different dimensions of sustainability, particularly the system-wide implications of human actions. This basic understanding further includes a sense of the time scale of possible future events and the limits of what is and is not likely to be possible. With this understanding, systematic approaches can then be used to develop policy guidelines for the system. This article presents an illustration of these ideas by analyzing an integrated ecological-economic-social model, which comprises various ecological (natural) and domesticated compartments representing species along with a macroeconomic price setting model. The stable and qualitatively realistic model is used to analyze different relevant scenarios. Apart from highlighting complex relationships within the system, it identifies potentially unsustainable future developments such as increased human per capita consumption rates. Dynamic optimization is then used to develop time-dependent policy guidelines for the unsustainable scenarios using objective functions that aim to minimize fluctuations in the system's Fisher information. The results can help to identify effective policy parameters and highlight the tradeoff between natural and domesticated compartments while managing such integrated systems. The results should also qualitatively guide further investigations in the area of system level studies and policy development.

How Earth Educators Can Help Students Develop a Holistic Understanding of Sustainability

2017-12-01

With their expert understanding of planetary systems, Earth educators play a pivotal role in helping students understand the scientific dimensions of solution-resistant ("wicked") challenges to sustainability that arise from complex interactions between intertwined and co-evolving natural and human systems. However, teaching the science of sustainability in isolation from consideration of human values and social dynamics leaves students with a fragmented understanding and obscures the underlying drivers of unsustainability. Geoscience instructors who wish to address sustainability in their courses may feel ill-equipped to engage students in investigation of the fundamental nature of sustainability and its social and ethical facets. This presentation will blend disciplinary perspectives from Earth system science, philosophy, psychology, and anthropology to: 1) outline a way to conceptualize sustainability that synthesizes scientific, social, and ethical perspectives and 2) provide an overview of resources and teaching strategies designed to help students connect science content to the socio-political dimensions of sustainability through activities and assignments that promote active learning, systems thinking, reflection, and collaborative problem-solving.

Embodied niche construction in the hominin lineage: semiotic structure and sustained attention in human embodied cognition

Science.gov (United States)

Stutz, Aaron J.

2014-01-01

Human evolution unfolded through a rather distinctive, dynamically constructed ecological niche. The human niche is not only generally terrestrial in habitat, while being flexibly and extensively heterotrophic in food-web connections. It is also defined by semiotically structured and structuring embodied cognitive interfaces, connecting the individual organism with the wider environment. The embodied dimensions of niche-population co-evolution have long involved semiotic system construction, which I hypothesize to be an evolutionarily primitive aspect of learning and higher-level cognitive integration and attention in the great apes and humans alike. A clearly pre-linguistic form of semiotic cognitive structuration is suggested to involve recursively learned and constructed object icons. Higher-level cognitive iconic representation of visually, auditorily, or haptically perceived extrasomatic objects would be learned and evoked through indexical connections to proprioceptive and affective somatic states. Thus, private cognitive signs would be defined, not only by their learned and perceived extrasomatic referents, but also by their associations to iconically represented somatic states. This evolutionary modification of animal associative learning is suggested to be adaptive in ecological niches occupied by long-lived, large-bodied ape species, facilitating memory construction and recall in highly varied foraging and social contexts, while sustaining selective attention during goal-directed behavioral sequences. The embodied niche construction (ENC) hypothesis of human evolution posits that in the early hominin lineage, natural selection further modified the ancestral ape semiotic adaptations, favoring the recursive structuration of concise iconic narratives of embodied interaction with the environment.

Full Text Available Cities are the most dramatic manifestations of human activities on the surface of the earth. These human-dominated organisms—i.e., cities—degrade natural habitats, simplify species composition, disrupt hydrological systems, and modify energy flow and nutrient cycling. Today, these consequential impacts of human activities, originated from population increase, rapid urbanization, high private motor vehicle dependency, deregulated industrialization and mass livestock production, are increasing exponentially and causing great deal of environmental, social, and economic challenges both at global and local scales. In such a situation, establishment of sustainable cities, through sustainable urban development practices, is seen as a potential panacea to combat these challenges responsibly, effectively, and efficiently. This paper offers a critical review of the key literature on the issues relating to planning, development and management of sustainable cities, introduces the contributions from the Special Issue, and speculates on the prospective research directions to place necessary mechanisms to secure a sustainable urban future for all.

Digital Earth - A sustainable Earth

All life, particularly human, cannot be sustainable, unless complimented with shelter, poverty reduction, provision of basic infrastructure and services, equal opportunities and social justice. Yet, in the context of cities, it is believed that they can accommodate more and more people, endlessly, regardless to their carrying capacity and increasing ecological footprint. The 'inclusion', for bringing more and more people in the purview of development is often limited to social and economic inclusion rather than spatial and ecological inclusion. Economic investment decisions are also not always supported with spatial planning decisions. Most planning for a sustainable Earth, be at a level of rural settlement, city, region, national or Global, fail on the capacity and capability fronts. In India, for example, out of some 8,000 towns and cities, Master Plans exist for only about 1,800. A chapter on sustainability or environment is neither statutorily compulsory nor a norm for these Master Plans. Geospatial technologies including Remote Sensing, GIS, Indian National Spatial Data Infrastructure (NSDI), Indian National Urban Information Systems (NUIS), Indian Environmental Information System (ENVIS), and Indian National GIS (NGIS), etc. have potential to map, analyse, visualize and take sustainable developmental decisions based on participatory social, economic and social inclusion. Sustainable Earth, at all scales, is a logical and natural outcome of a digitally mapped, conceived and planned Earth. Digital Earth, in fact, itself offers a platform to dovetail the ecological, social and economic considerations in transforming it into a sustainable Earth.

Toward A Science of Sustainable Water Management

Brown, C.

2016-12-01

Societal need for improved water management and concerns for the long-term sustainability of water resources systems are prominent around the world. The continued susceptibility of society to the harmful effects of hydrologic variability, pervasive concerns related to climate change and the emergent awareness of devastating effects of current practice on aquatic ecosystems all illustrate our limited understanding of how water ought to be managed in a dynamic world. The related challenges of resolving the competition for freshwater among competing uses (so called "nexus" issues) and adapting water resources systems to climate change are prominent examples of the of sustainable water management challenges. In addition, largely untested concepts such as "integrated water resources management" have surfaced as Sustainable Development Goals. In this presentation, we argue that for research to improve water management, and for practice to inspire better research, a new focus is required, one that bridges disciplinary barriers between the water resources research focus on infrastructure planning and management, and the role of human actors, and geophysical sciences community focus on physical processes in the absence of dynamical human response. Examples drawn from climate change adaptation for water resource systems and groundwater management policy provide evidence of initial progress towards a science of sustainable water management that links improved physical understanding of the hydrological cycle with the socioeconomic and ecological understanding of water and societal interactions.

Sustainable procurement portfolio management: a case study in a mining company

Tamires Magalhães de Mello

Full Text Available Abstract Sustainable procurement is a solution to integrate environmental and social considerations in all steps of procurement process, in order to reduce impacts on human health, environment, and human rights. Despite the existence of important works in this area, more studies for determining how the principles related to sustainable development can be integrated to procurement strategies are needed. This study presents a case study in a mining company to evaluate the elements that should be considered for the implementation of sustainability concept in the contracting of services through the application of a sustainability portfolio model. Results show that the contracts of the internal movement's category of the studied company fit as Strategic Commodity, which means that the items in this category have a risk in the strategic supply, because they need investments made by the buyer in the relationship with the supplier.

Crises in climate, food, biodiversity, and energy are already playing out across local and global scales and are set to increase as we approach critical thresholds. Drawing together recent work from the Stockholm Resilience Centre, the Tellus Institute, and the STEPS Centre, this commentary article argues that ambitious Sustainable Development Goals are now required along with major transformation, not only in policies and technologies, but in modes of innovation themselves, to meet them. As examples of dryland agriculture in East Africa and rural energy in Latin America illustrate, such "transformative innovation" needs to give far greater recognition and power to grassroots innovation actors and processes, involving them within an inclusive, multi-scale innovation politics. The three dimensions of direction, diversity, and distribution along with new forms of "sustainability brokering" can help guide the kinds of analysis and decision making now needed to safeguard our planet for current and future generations.

Presence may occur when actors are alert and relaxed in performance. A positive mood is associated with physical activity, but little is known about how movement qualities affect mood and vital signs of actors. This study examined the effects of vibratory, pendular, abrupt, and sustained movement qualities on the Brief Mood Introspection Scale,…

It is widely accepted that the cell of origin of breast cancer is the adult mammary epithelial stem cell; however, demonstrating the presence and location of tissue stem cells in the human breast has proved difficult. Furthermore, we do not know the clonal architecture of the normal and premalignant mammary epithelium or its cellular hierarchy. Here, we use deficiency in the mitochondrial enzyme cytochrome c oxidase (CCO), typically caused by somatic mutations in the mitochondrial genome, as a means to perform lineage tracing in the human mammary epithelium. PCR sequencing of laser-capture microdissected cells in combination with immunohistochemistry for markers of lineage differentiation was performed to determine the clonal nature of the mammary epithelium. We have shown that in the normal human breast, clonal expansions (defined here by areas of CCO deficiency) are typically uncommon and of limited size, but can occur at any site within the adult mammary epithelium. The presence of a stem cell population was shown by demonstrating multi-lineage differentiation within CCO-deficient areas. Interestingly, we observed infrequent CCO deficiency that was restricted to luminal cells, suggesting that niche succession, and by inference stem cell location, is located within the luminal layer. CCO-deficient areas appeared large within areas of ductal carcinoma in situ, suggesting that the rate of clonal expansion was altered in the premalignant lesion. © 2017 The Authors.

2011-01-01

Human spaceflight organizations have ambitious goals for expanding human presence throughout the solar system. To meet these goals, spaceflight organizations have to overcome complex technical challenges for human missions to Mars, Near Earth Asteroids, and other distant celestial bodies. Resolving these challenges requires considerable resources and technological innovations, such as advancements in human health and countermeasures for space environments; self-sustaining habitats; advanced power and propulsion systems; and information technologies. Today, government space agencies seek cooperative endeavors to reduce cost burdens, improve human exploration capabilities, and foster knowledge sharing among human spaceflight organizations. This paper looks at potential opportunities for partnerships and spin-ins from economic sectors outside the space industry. It highlights innovative technologies and breakthrough concepts that could have significant impacts on space exploration and identifies organizations throughout the broader economy that specialize in these technologies.

In 2015, the energy transition law for green growth is creating a momentum which removes obstacles, boosts initiatives and enables everyone to act. All stakeholders, local authorities, NGO's, businesses and citizens are gradually building a new social model that combines economic, ecological and human progress. Building on that momentum, the national strategy of ecological transition towards sustainable development (SNTEDD) 2015-2020 replaces the national sustainable development strategy 2010-2013 by setting us on a new path to sustainable development. The national strategy of ecological transition towards sustainable development ensures the consistency of public policies and facilitates people's ownership

Vegetation, population and ecological track as sustainability indicators in Colombia

International Nuclear Information System (INIS)

Marquez Calle, German

2000-01-01

Biophysical sustainability, namely natural capabilities to sustain human development in Colombia, is explored through environmental indicators based on land cover and demographic variables. Remnant vegetation index (IVR in Spanish) uses cover as a measure of ecosystem functionality. Population pressure index (IPD) applies population density to environmental demand analysis. Footprint index (IHE) relates the inverse of density with sustainability. Environmental criticality index combines IVR and IPD to detect offer/demand unbalances. Results suggest Colombia is sustainable although many places in it could be in danger; this could be related with social and economical features of the country

The ecological sustainability trigon - A proposed conceptual framework for creating and testing management scenarios

International Nuclear Information System (INIS)

Marques, J.C.; Basset, A.; Brey, T.; Elliott, M.

2009-01-01

The ability to achieve ecological sustainability and the sustainable development of marine and estuarine ecosystems constitutes a complex major challenge and depends on many driving forces, often conflicting with each other. In particular, there are three major drivers: (a) the search for human well-being, health and safety, (b) the maintenance of ecological sustainability and environmental equilibrium, and (c) the tolerance of an increasing human population pressure and demand for wealth creation. We propose here the use of a conceptual guidance tool - the ecological sustainability trigon (EST) - as a means of building and testing environmental management scenarios. Although it requires further testing, the EST allows us to (a) address those three major drivers using human society view as a common currency, and (b) describe our behaviour, energetics (economy) and dynamics through ecological theory. Moreover, the EST appears promising for gap analysis and the means to address new research questions.

Sustainable diets within sustainable food systems.

Science.gov (United States)

Meybeck, Alexandre; Gitz, Vincent

2017-02-01

Sustainable diets and sustainable food systems are increasingly explored by diverse scientific disciplines. They are also recognised by the international community and called upon to orient action towards the eradication of hunger and malnutrition and the fulfilment of sustainable development goals. The aim of the present paper is to briefly consider some of the links between these two notions in order to facilitate the operationalisation of the concept of sustainable diet. The concept of sustainable diet was defined in 2010 combining two totally different perspectives: a nutrition perspective, focused on individuals, and a global sustainability perspective, in all its dimensions: environmental, economic and social. The nutrition perspective can be easily related to health outcomes. The global sustainability perspective is more difficult to analyse directly. We propose that it be measured as the contribution of a diet to the sustainability of food systems. Such an approach, covering the three dimensions of sustainability, enables identification of interactions and interrelations between food systems and diets. It provides opportunities to find levers of change towards sustainability. Diets are both the results and the drivers of food systems. The drivers of change for those variously involved, consumers and private individuals, are different, and can be triggered by different dimensions (heath, environment, social and cultural). Combining different dimensions and reasons for change can help facilitate the transition to sustainable diets, recognising the food system's specificities. The adoption of sustainable diets can be facilitated and enabled by food systems, and by appropriate policies and incentives.

Self-feedbacks determine the sustainability of human interventions in eco-social complex systems: Impacts on biodiversity and ecosystem health.

Science.gov (United States)

Ortiz, Marco; Levins, Richard

2017-01-01

Several administrative polices have been implemented in order to reduce the negative impacts of fishing on natural ecosystems. Four eco-social models with different levels of complexity were constructed, which represent the seaweed harvest in central-northern Chile under two different regimes, Management and Exploitation Areas for Benthic Resources (MAEBRs) and Open Access Areas (OAAs). The dynamics of both regimes were analyzed using the following theoretical frameworks: (1) Loop Analysis, which allows the local stability or sustainability of the models and scenarios to be assessed; and (2) Hessian´s optimization procedure of a global fishery function (GFF) that represents each dynamics of each harvest. The results suggest that the current fishing dynamics in MAEBRs are not sustainable unless the market demand presents some type of control (i.e. taxes). Further, the results indicated that if the demand changes to a self-negative feedback (self-control) in MAEBRs, the stability is increased and, simultaneously, a relative maximum for the GFF is reached. Contrarily, the sustainability of the model/system representing the harvest (principally by cutting plants) in OAAs is not reached. The implementation of an "ecological" tax for intensive artisanal fisheries with low operational cost is proposed. The network analysis developed here is proposed as a general strategy for studying the effects of human interventions in marine coastal ecosystems under transient (short-term) dynamics.

With over 30% global land coverage, the forest is one of nature's most generous gifts to human beings, providing shelters and materials for all living beings. Apart from being sustainable, renewable, and biodegradable, wood and its derivative materials are also extremely fascinating from a materials aspect, with numerous advantages including porous and hierarchical structure, excellent mechanical performance, and versatile chemistry. Here, strategies for designing novel wood-based materials via advanced nanotechnologies are summarized, including both the controllable bottom-up assembly from the highly crystalline nanocellulose building block and the more efficient top-down approaches directly from wood. Beyond material design, recent advances regarding the sustainable applications of these novel wood-based materials are also presented, focusing on areas that are traditionally dominated by man-made nonrenewable materials such as plastic, glass, and metals, as well as more advanced applications in the areas of energy storage, wastewater treatment and solar-steam-assisted desalination. With all recent progress pertaining to materials' design and sustainable applications presented, a vision for the future engineering of wood-based materials to promote continuous and healthy progress toward true sustainability is outlined. © 2017 WILEY-VCH Verlag GmbH & Co.

CONCEPTUAL DELIMITATIONS ON SUSTAINABLE DEVELOPMENT

Directory of Open Access Journals (Sweden)

Ienciu Ionel-Alin

2013-07-01

Full Text Available Sustainable development is a model for resource use meant to satisfy human needs, without polluting the environment, so that these needs can be satisfied not only in the present, but in the future as well. It is a concept of nowadays with no generally accepted definition, placing environment first and foremost, aiming at implementing the environmental policies in all structures and at all economic levels. Within the present study we have aimed at creating a conceptual delimitation on sustainable development, sustainability and socialresponsibility, concepts of present interest, that tend to become a mystery for the academic community and practitioners by their variety and complexity of approaches. During our scientific endeavor we believe that social responsibility is the foundation of sustainable development. Sustainable development is a concept used especially at macro-economic level, while social responsibility is used at entity level and incorporates the economic, environmental and social dimension, which has a voluntary character and tries to respond to the information needs of the society and other stakeholders. Sustainability at the entity\\'s level is the goal or final objective of sustainable development – satisfaction of present needs without compromising the possibility for future generations to satisfy their own needs, while social responsibility is an intermediate phase of sustainability wherein entities try to balance the economic, social and environmental dimension. Thus, we can state we include ourselves within social corporatism, slightly close to social institutionalism, which is characteristic to developed countries, giving a particular importance to social contract and relations between entity and society. We believe that in Romania, a POSDRU funded project should be regarded as a legal person with social values, which must be based on sustainable development and to promote, besides legal liability of automatically deriving

Full Text Available This paper is about the position of workforce and employment considerations within the sustainable tourism narrative. The paper aims to address the relative neglect of this area within the discourse of sustainable tourism and highlights references to the workforce within the United Nations’ 2030 Agenda for Sustainable Development. The discussion follows the emerging field of sustainable human resource management and the contribution that this can make to meeting both the UN Sustainable Development Goals and to enhancing the recognition of workforce and employment issues within the related debate in tourism. The body of the paper highlights examples of key dimensions of work and employment across varied tourism contexts, where sustainability is of increasing consequence and significance. The paper concludes by drawing together the implications of these “mini-cases” and locating them within key principles of the 2030 Agenda for Sustainable Development.

From Intuitive Programming of Robotic Systems to Business Sustainability of Manufacturing SMEs

Directory of Open Access Journals (Sweden)

Bogdan Mocan

2016-02-01

Full Text Available Economic growth and sustainable development are issues which are becoming more and more important for nowadays companies. Sustainable development strives for moderate and responsible use within the economic and production activity the limited resources of our planet. Eco-innovations, eco-efficiency and corporate social responsibility practices define much of the current industrial sustainability agenda. While important, they are insufficient in themselves to deliver the holistic changes necessary to achieve long-term social and environmental sustainability. This paper proposed a framework for designing multimodal human-robot interfaces and a demonstrator that facilitate a sustainable use of robotic systems with positive effects on SMEs business sustainability. The proposed approach is intended to bring important contributions to the development of human robot interaction in order to facilitate intuitive programming and to enable easily adapting to changes in robot tasks and applications without the need of using skilled personnel. Our research emphasize the idea that new technologies in product and process create and enable new business strategies; and we demonstrate that changing the paradigm in programming industrial robotic systems it is possible by a “business case for sustainability” to have a sustainable development of the business, in special in case of SMEs.

Hunting with lead ammunition is not sustainable: European perspectives.

Kanstrup, Niels; Swift, John; Stroud, David A; Lewis, Melissa

2018-03-12

Much evidence demonstrates the adverse effects of lead ammunition on wildlife, their habitats and human health, and confirms that the use of such ammunition has no place within sustainable hunting. We identify the provisions that define sustainable hunting according to European law and international treaties, together with their guidance documents. We accept the substantial evidence for lead's actual and potential effects on wildlife, habitats and health as persuasive and assess how these effects relate to stated provisions for sustainability and hunting. We evaluate how continued use of lead ammunition negatively affects international efforts to halt loss of biodiversity, sustain wildlife populations and conserve their habitats. We highlight the indiscriminate and avoidable health and welfare impacts for large numbers of exposed wild animals as ethically unsustainable. In societal terms, continued use of lead ammunition undermines public perceptions of hunting. Given the existence of acceptable, non-toxic alternatives for lead ammunition, we conclude that hunting with lead ammunition cannot be justified under established principles of public/international policy and is not sustainable. Changing from lead ammunition to non-toxic alternatives will bring significant nature conservation and human health gains, and from the hunter's perspective will enhance societal acceptance of hunting. Change will create opportunities for improved constructive dialogue between hunting stakeholders and others engaged with enhancing biodiversity and nature conservation objectives.

Experimental studies of Plasmodium parasites that infect humans are restricted by their host specificity. Humanized mice offer a means to overcome this and further provide the opportunity to observe the parasites in vivo. Here we improve on previous protocols to achieve efficient double engraftment of TK-NOG mice by human primary hepatocytes and red blood cells. Thus, we obtain the complete hepatic development of P. falciparum, the transition to the erythrocytic stages, their subsequent multiplication, and the appearance of mature gametocytes over an extended period of observation. Furthermore, using sporozoites derived from two P. ovale-infected patients, we show that human hepatocytes engrafted in TK-NOG mice sustain maturation of the liver stages, and the presence of late-developing schizonts indicate the eventual activation of quiescent parasites. Thus, TK-NOG mice are highly suited for in vivo observations on the Plasmodium species of humans.

Little, John C; Hester, Erich T; Carey, Cayelan C

2016-07-05

While sustainability is an essential concept to ensure the future of humanity and the integrity of the resources and ecosystems on which we depend, identifying a comprehensive yet realistic way to assess and enhance sustainability may be one of the most difficult challenges of our time. We review the primary environmental sustainability assessment approaches, categorizing them as either being design-based or those that employ computational frameworks and/or indicators. We also briefly review approaches used for assessing economic and social sustainability because sustainability necessitates integrating environmental, economic, and social elements. We identify the collective limitations of the existing assessment approaches, showing that there is not a consistent definition of sustainability, that the approaches are generally not comprehensive and are subject to unintended consequences, that there is little to no connection between bottom-up and top-down approaches, and that the field of sustainability is largely fragmented, with a range of academic disciplines and professional organizations pursuing similar goals, but without much formal coordination. We conclude by emphasizing the need for a comprehensive definition of sustainability (that integrates environmental, economic, and social aspects) with a unified system-of-systems approach that is causal, modular, tiered, and scalable, as well as new educational and organizational structures to improve systems-level interdisciplinary integration.

The chrondoprotective actions of a natural product are associated with the activation of IGF-1 production by human chondrocytes despite the presence of IL-1β

Directory of Open Access Journals (Sweden)

Bobrowski Paul

2006-04-01

Full Text Available Abstract Background Cartilage loss is a hallmark of arthritis and follows activation of catabolic processes concomitant with a disruption of anabolic pathways like insulin-like growth factor 1 (IGF-1. We hypothesized that two natural products of South American origin, would limit cartilage degradation by respectively suppressing catabolism and activating local IGF-1 anabolic pathways. One extract, derived from cat's claw (Uncaria guianensis, vincaria®, is a well-described inhibitor of NF-κB. The other extract, derived from the vegetable Lepidium meyenii (RNI 249, possessed an uncertain mechanism of action but with defined ethnomedical applications for fertility and vitality. Methods Human cartilage samples were procured from surgical specimens with consent, and were evaluated either as explants or as primary chondrocytes prepared after enzymatic digestion of cartilage matrix. Assessments included IGF-1 gene expression, IGF-1 production (ELISA, cartilage matrix degradation and nitric oxide (NO production, under basal conditions and in the presence of IL-1β. Results RNI 249 enhanced basal IGF-1 mRNA levels in human chondrocytes by 2.7 fold, an effect that was further enhanced to 3.8 fold by co-administration with vincaria. Enhanced basal IGF-1 production by RNI 249 alone and together with vincaria, was confirmed in both explants and in primary chondrocytes (P Conclusion The identification of agents that activate the autocrine production of IGF-1 in cartilage, even in the face of suppressive pro-inflammatory, catabolic cytokines like IL-1β, represents a novel therapeutic approach to cartilage biology. Chondroprotection associated with prevention of the catabolic events and the potential for sustained anabolic activity with this natural product suggests that it holds significant promise in the treatment of debilitating joint diseases.

2018-03-01

The relationship between sustainability and the Anthropocene takes on new meaning in a time of unprecedented human impact on Earth systems. This relationship is at times contested and not well researched but critical in considering how we will respond to environmental challenges of today and the future. Elaborating on the need for new perspectives and nuanced understandings of sustainability, the contributors to this volume draw on posthumanist and "new" feminist materialist methodologies and theoretical lenses to engage readers in ways, which often contrast with prevailing thinking and research. From the cosmopolitics of place in urban Berlin to the watery space of urban wetlands they share research and rich narratives, which illustrate how sustainability is theorized and enacted across a range of diverse educational contexts. Moving beyond the rhetoric of sustainability, the authors invite us to explore innovative ways to engage with new concepts and emerging tensions that are now influencing the fields of education and sustainability.

Embodied Niche Construction in the Hominin Lineage: Semiotic Structure and Sustained Attention in Human Embodied Cognition

Directory of Open Access Journals (Sweden)

Aaron Jonas Stutz

2014-08-01

Full Text Available Human evolution unfolded through a rather distinctive, dynamically constructed ecological niche. The human niche is not only generally terrestrial in habitat, while being flexibly and extensively heterotrophic in food-web connections. It is also defined by semiotically structured and structuring embodied cognitive interfaces, connecting the individual organism with the wider environment. The embodied dimensions of niche-population co-evolution have long involved semiotic system construction, which I hypothesize to be an evolutionarily primitive aspect of learning and higher-level cognitive integration and attention in the great apes and humans alike. A clearly pre-linguistic form of semiotic cognitive structuration is suggested to involve recursively learned and constructed object icons. Higher-level cognitive iconic representation of visually, auditorily, or haptically perceived extrasomatic objects would be learned and evoked through indexical connections to proprioceptive and affective somatic states. Thus, private cognitive signs would be defined, not only by their learned and perceived extrasomatic referents, but also by their associations to iconically represented somatic states. This evolutionary modification of animal associative learning is suggested to be adaptive in ecological niches occupied by long-lived, large-bodied ape species, facilitating memory construction and recall in highly varied foraging and social contexts, while sustaining selective attention during goal-directed behavioral sequences. The embodied niche construction (ENC hypothesis of human evolution posits that in the early hominin lineage, natural selection further modified the ancestral ape semiotic adaptations, favoring the recursive structuration of concise iconic narratives of embodied interaction with the environment.

Effects of ultraviolet-visible irradiation in the presence of melanin isolated from human black or red hair upon Ehrlich ascites carcinoma cells

Energy Technology Data Exchange (ETDEWEB)

Menon, I.A.; Persad, S.; Ranadive, N.S.; Haberman, H.F.

1983-07-01

The present study is an attempt to investigate the possibility that ultraviolet irradiation in the presence of pheomelanin may be more harmful to cells than the irradiation in the presence of eumelanin. The effects of UV-visible irradiation upon Ehrlich ascites carcinoma cells in the presence of the melanin isolated from human black hair (eumelanin) or from red hair (pheomelanin) were investigated. Irradiation of these cells was found to produce cell lysis, as observed by leakage of 51Cr from labeled cells and intracellular lactic dehydrogenase from the cells and decrease in cell viability demonstrated by the trypan blue exclusion test. The three parameters were quantitatively parallel to one another under various experimental conditions, namely different periods of irradiation and irradiation in the presence of different concentrations of melanin. The above effects were more pronounced when the irradiation was carried out in the presence of melanin from red hair than in the presence of black-hair melanin. In the absence of either melanin, the irradiation did not produce any significant effect in cell viability or cell lysis. Irradiation of the cells in the presence of red-hair melanin also decreased the transplantability of these cells. These observations clearly show that irradiation of cells in the presence of pheomelanin could produce cytotoxic effects. The present experimental design may have application in the development of in vitro models for the study of UV radiation-induced cutaneous carcinogenesis. The reactions of pheomelanin may be related to the susceptibility of ''Celtic'' skin to UV radiation-induced skin damage and carcinogenesis.

Human resources for health strategies adopted by providers in resource-limited settings to sustain long-term delivery of ART: a mixed-methods study from Uganda.

Human resources for health (HRH) constraints are a major barrier to the sustainability of antiretroviral therapy (ART) scale-up programs in Sub-Saharan Africa. Many prior approaches to HRH constraints have taken a top-down trend of generalized global strategies and policy guidelines. The objective of the study was to examine the human resources for health strategies adopted by front-line providers in Uganda to sustain ART delivery beyond the initial ART scale-up phase between 2004 and 2009. A two-phase mixed-methods approach was adopted. In the first phase, a survey of a nationally representative sample of health facilities (n = 195) across Uganda was conducted. The second phase involved in-depth interviews (n = 36) with ART clinic managers and staff of 6 of the 195 health facilities purposively selected from the first study phase. Quantitative data was analysed based on descriptive statistics, and qualitative data was analysed by coding and thematic analysis. The identified strategies were categorized into five themes: (1) providing monetary and non-monetary incentives to health workers on busy ART clinic days; (2) workload reduction through spacing ART clinic appointments; (3) adopting training workshops in ART management as a motivation strategy for health workers; (4) adopting non-physician-centred staffing models; and (5) devising ART program leadership styles that enhanced health worker commitment. Facility-level strategies for responding to HRH constraints are feasible and can contribute to efforts to increase country ownership of HIV programs in resource-limited settings. Consideration of the human resources for health strategies identified in the study by ART program planners and managers could enhance the long-term sustainment of ART programs by providers in resource-limited settings.

Full Text Available The interest in corporate sustainability has increased rapidly in recent years and has encouraged organizations to adopt appropriate digital communication strategies, in which the corporate website plays a key role. Despite this growing attention in both the academic and business communities, models for the analysis and evaluation of online sustainability communication have not been developed to date. This paper aims to develop an operational model to identify and assess the requirements of sustainability communication in corporate websites. It has been developed from a literature review on corporate sustainability and digital communication and the analysis of the websites of the organizations included in the “Global CSR RepTrak 2015” by the Reputation Institute. The model identifies the core dimensions of online sustainability communication (orientation, structure, ergonomics, content—OSEC, sub-dimensions, such as stakeholder engagement and governance tools, communication principles, and measurable items (e.g., presence of the materiality matrix, interactive graphs. A pilot study on the websites of the energy and utilities companies included in the Dow Jones Sustainability World Index 2015 confirms the applicability of the OSEC framework. Thus, the model can provide managers and digital communication consultants with an operational tool that is useful for developing an industry ranking and assessing the best practices. The model can also help practitioners to identify corrective actions in the critical areas of digital sustainability communication and avoid greenwashing.

This study examines to what extent corporations use sustainability control systems (SCS) to translate proactive sustainability strategy into corporate sustainability performance. The study investigates the mediating effect of SCS on the relationship between proactive sustainability strategy and corporate sustainability performance. Survey data were collected from top managers in 175 multinational and local corporations operating in Sri Lanka and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). SCS were observed to only partially mediate the relationship between proactive sustainability strategy and corporate sustainability performance. The mediating effect of SCS is further examined under three sustainability strategies; environmental and social strategies reveal a partial mediation, while the economic strategy exhibits no mediation. The study also finds that (i) a proactive sustainability strategy is positively associated with SCS and corporate sustainability performance and (ii) SCS are positively associated with corporate sustainability performance.

The remediation industry has grown exponentially in recent decades. International organizations of practitioners and remediation experts have developed several frameworks for integrating sustainability into remediation projects; however, there has been limited attention to how sustainability is approached and operationalized in sustainable remediation frameworks and practices - or whether sustainability plays any meaningful role at all in sustainable remediation. This paper examines how sustainability is represented in remediation frameworks and the guidance provided for practical application. Seven broad sustainability principles and review criteria are proposed and applied to a sample of six international remediation frameworks. Not all review criteria were equally satisfied and none of the frameworks fully met all criteria; however, the best performing frameworks were those identified as sustainability remediation frameworks. Intra-generational equity was addressed by all frameworks. Integrating social, economic and biophysical components beyond triple-bottom-line indicators was explicitly addressed only by the sustainable remediation frameworks. No frameworks provided principle- or rule-based guidance for dealing with trade-offs in sustainability decisions. Copyright © 2016 Elsevier Ltd. All rights reserved.

Development towards sustainability: how to judge past and proposed policies?

Most countries have, at least since the 1992 United Nations summit in RIO, adopted some vague "sustainable development" policies. The goals of such policies are to combine economic growth with social development, while protecting our fragile planetary life support system. The scientific data about the state of our planet, presented at the 2012 (Rio+20) summit, documented that today's human family lives even less sustainably than it did in 1992. The data indicate furthermore that the environmental impacts from our current economic activities are so large, that we are approaching situations where potentially controllable regional problems can easily lead to uncontrollable global disasters. Despite these obvious failures, our political global leaders and their institutions are continuing the same "sustainable development" policies, which are now supplemented by equally vague ideas about future "green economies". Assuming that (1) the majority of the human family, once adequately informed, wants to achieve a "sustainable way of life" and (2) that the "development towards sustainability" roadmap will be based on scientific principles, one must begin with unambiguous and quantifiable definitions of these goals. As will be demonstrated, the well known scientific method to define abstract and complex issues by their negation, satisfies these requirements. Following this new approach, it also becomes possible to decide if proposed and actual policy changes will make our way of life less unsustainable, and thus move us potentially into the direction of sustainability. Furthermore, if potentially dangerous tipping points are to be avoided, the transition roadmap must include some minimal speed requirements. Combining the negation method and the time evolution of that remaining natural capital in different domains, the transition speed for a "development towards sustainability" can be quantified at local, regional and global scales. The presented ideas allow us to measure the

Full Text Available The turbulent development of human civilization is faced with the serious challenge of its sustainability. Despite the fact that, declaratively, discourses in academic, scientific and political circles point out all the urgency of resolving this issue of further development of human society, there are few reversals and changes in the functioning of economic and social systems so far. The issue of sustainability has two dominant dimensions - economic, in the sense of exploitation of natural resources and environment pollution, and social, in the sense of actual responsible behavior and inequality of individuals in terms of meeting basic and broader human needs. This paper is an attempt at contributing to the development of the awareness of the problem of development of society and consumption in it, and pointing at possible avenues of acting of relevant individuals and institutions in this sense, through studying attitudes, level of consciousness and perceptions of sustainable consumption, and through the measurement of the environmental and social dimensions, analysing the significance and actual behaviour of respondents from Generation Y, i.e. generation born after 1980, very often in the focus of research of marketing theory and practice. The paper discloses that there is a significant disproportion between the significance of individual elements of sustainability for individual, and actual behaviour of the respondents in regard of sustainable consumption.

Full Text Available Sustainable Drainage Systems (SuDS are today widely considered to be a more progressive and environmentally sensitive approach to Flood Risk Management (FRM. However, this paper argues that the sustainability of SuDS should not be so simply presumed. Devices will depend upon correct behaviour from those local to them in order to function properly over time, and for Green Infrastructure SuDS to flourish and deliver their promised multiple benefits. This paper looks to the potential value in using Social Practice Theory as a lens for understanding current behaviours around SuDS devices, and for assessing possible strategies for encouraging positive behaviour amongst affected communities. It concludes in arguing that involving local people as much as possible in the co-design of systems and then working to maintain involvement and awareness will be the most cost-effective means by which SuDS might be made to live up to the sustainability they are celebrated for.

Full Text Available An eco-village as defined by Robert Gilman is a “human-scale, full-featured settlement where you feel you know the others, and human activities are integrated with natural, biological systems.” Roland Mayerl argued that this maybe ideal, but there are huge challenges. He claims the challenges are at different levels—there is the physical layer that constitutes food production, animals, water and wastewater treatment. Other layers will be the built environment, the economic system and the governance in the village.This paper argues that one of the challenging layers is the human layer that was excluded in the modeling of many eco-village works. While there are many good models of an eco-village, sustainability will primarily be laid on the shoulders of the members of the community or the village for that matter. Sustainability should be espoused by the members of the eco-village. But how can sustainability be attained? What sustainability approach or strategy can be employed?“Communities of practice (COP are formed by people who engage in a process of collective learning in a shared domain of human endeavor.“ (Wenger, 2004 COPs are concepts commonly applied in organizations and virtual communities. Using this approach together with periphery participation and situated learning, this paper presents a human-based model of a sustainable eco-village and some useful examples.The paper also argues that an eco-village necessitates the support of technology in enhancing and preserving the shared practices. Hence, use of social media deployed in the web is one of the recommended ways that also permit collective action among members of the eco-village.

In the field of controlled drug delivery, most of the reported work is aimed at introducing new systems, or at providing basic information on the critical parameters which affect release profiles in vitro and occasionally in vivo. The situation is totally different when one wants to fulfil the specific requirements imposed by the marketing of a sustained release device to be used in humans or in animals eaten by human beings. The control of the release characteristics is then a difficult challenge. In this work, attempts were made to combine cephradin, a hydrophilic beta-lactam antibiotic, and bioresorbable polymeric matrices of a poly(alpha-hydroxy acid) in the form of microspheres with the aim of delivering the antibiotic to cattle at a dose rate of 4-5 mg/kg/day over a 3-4 days period after i.m. injection. PLAGA aliphatic polyesters were selected because they are already FDA approved as matrices. The solvent evaporation technique using PVA as the emulsion stabilizer was selected because it is efficient and can be extended to an industrial scale. Various experimental conditions were used in order to obtain the highest encapsulation yields compatible with the desired specifications. Decreasing the volume of the aqueous phase and adding a water-miscible organic solvent/non-solvent of cephradin failed. In contrast, microspheres containing up to 30% cephradin were prepared after addition of sodium chloride to the aqueous dispersing phase. The amount of entrapped drug was raised to 40% by decreasing the temperature and the pressure. Preliminary investigations using dogs showed that 20% cephradin microspheres prepared under these conditions extended the presence of cephradin in the blood circulation up to 48 h. Increasing the load led to higher blood concentrations but shorter sustained release. The fact that the microspheres were for cattle limited the volume of the injection and thus the amount of microspheres to be administered. The other limiting factors were

Full Text Available Modern manufacturing systems should satisfy emerging needs related to sustainable development. The design of sustainable manufacturing systems can be valuably supported by simulation, traditionally employed mainly for time and cost reduction. In this paper, a multi-purpose digital simulation approach is proposed to deal with sustainable manufacturing systems design through Discrete Event Simulation (DES and 3D digital human modelling. DES models integrated with data on power consumption of the manufacturing equipment are utilized to simulate different scenarios with the aim to improve productivity as well as energy efficiency, avoiding resource and energy waste. 3D simulation based on digital human modelling is employed to assess human factors issues related to ergonomics and safety of manufacturing systems. The approach is implemented for the sustainability enhancement of a real manufacturing cell of the aerospace industry, automated by robotic deburring. Alternative scenarios are proposed and simulated, obtaining a significant improvement in terms of energy efficiency (−87% for the new deburring cell, and a reduction of energy consumption around −69% for the coordinate measuring machine, with high potential annual energy cost savings and increased energy efficiency. Moreover, the simulation-based ergonomic assessment of human operator postures allows 25% improvement of the workcell ergonomic index.

Humanity has reaped great benefits from mining. Over the millennia that humans have practiced mining, there have been many obvious improvements in mining’s environmental and social impacts. However, some aspects of mining still involve an element of ecological violence and, in Australia, there is a growing amount of conflict concerned with mining. These two related issues – ‘ecological violence’ and ‘conflict’ – were explored at the ‘Mining in a Sustainable World’ conference on 13 to 15 Octob...

Science.gov (United States)

The MSSB is the first and only decision support tool containing information from scientific literature and technical reports that can be used to develop and implement sustainability initiatives. The MSSB is designed to assist individuals and communities in understanding the impacts that the four key dimensions of sustainability - Land Use, Buildings and Infrastructure, Transportation, and Materials Management - can have on human health, the economy, the built environment and natural environments. The MSSB has the following capabilities: a. Displays and describes linkages between the four major sustainability concepts (Land Use, Buildings and Infrastructure, Transportation, and Materials Management) and their subordinate concepts. b. Displays and lists literature sources and references (including weblinks where applicable) providing information about each major sustainability concept and its associated subordinate concepts. c. Displays and lists quantitative data related to each major sustainability concept and its associated subordinate concepts, with weblinks where applicable.The MSSB serves as a ‘visual database’, allowing users to: investigate one or more of the four key sustainability dimensions; explore available scientific literature references, and; assess potential impacts of sustainability activities. The MSSB reduces the amount of time and effort required to assess the state of sustainability science and engineering research pertaining

Despite decades of international experience with the use of information and communication technologies in healthcare delivery, widespread telehealth adoption remains limited and progress slow. Escalating health system challenges related to access, cost and quality currently coincide with rapid advancement of affordable and reliable internet based communication technologies creating unprecedented opportunities and incentives for telehealth. In this paper, we will describe how Human Factors Engineering (HFE) and user-centric elements have been incorporated into the establishment of telehealth within a large academic medical center to increase acceptance and sustainability. Through examples and lessons learned we wish to increase awareness of HFE and its importance in the successful implementation, innovation and growth of telehealth programs.
