The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of the system is found as 43.158%, while exergy efficiency 40.655%. Thermoeconomic analysis gives information about the costs of the inlet and outlet energy and exergy flows of the engine. Hourly levelized total cost flow of the TdAE is found as 21.036 $/h, when the hourly fuel cost flow of the engine is found as 30.328 $/h. The waste exergy cost parameter is determined as 0.0144 MJ/h/$ from exergy cost-energy-mass (EXCEM) analysis, while it is estimated as 14.043 MJ/$ from modified-EXCEM analysis. Environmental damage cost analysis evaluates the cost formation of the exhaust emissions. The total environmental damage cost of the TdAE is computed as 12.895 $/h whilst specific environmental damage cost is determined as 0.054 $/MJ for 494.145 MJ/h TdAE power production. It is assessed that the main contributors to the environmental impact rate of the TdAE are the fuel consumption and the formation pollutants of combustion reaction.

In this study, aviation, energy, exergy, environmental, exergoeconomic, and exergoenvironmental analyses are performed on a CFM56-3 series high by-pass turbofan engine fueled with Jet-A1 fuel. Specific fuel consumption and specific thrust of the engine are found to be 0.01098 kg/kN.s and 0.3178 kN/kg/s, respectively. Engine's energy efficiency is calculated as 35.37%, while waste energy ratio is obtained as 64.63%. Exergy efficiency, waste exergy rate, and fuel exergy waste ratio are forecasted as 33.32%, 33175.03 kW, and 66.68%, respectively. Environmental effect factor and ecological effect factor are computed as 2.001 and 3.001, while ecological objective function and its index are taken into account of −16597.22 kW and −1.001, respectively. Exergetic sustainability index and sustainable efficiency factor are determined as 0.5 and 1.5 for the CFM56-3 engine, respectively. Environmental damage cost rate is determined as 519.753 $/h, while the environmental damage cost index is accounted as 0.0314 $/kWh. Specific exergy cost of the engine production is found as 40.898 $/GJ from exergoeconomic analysis, while specific product exergy cost is expressed as 49.607 $/GJ from exergoenvironmental analysis. From exergoenvironmental economic analysis, specific exergy cost of fuel is computed as 10.103 $/GJ when specific exergy cost of production is determined as 40.898 $/GJ.

Theoretical trends and schools of thought in the field of anthropology evolve rapidly. Anthropological literature must keep abreast, not only of these intellectual shifts, but also of pressing global, political, and social issues. Thus, this volume, like others before it, seeks to provide updates on the state of the science and the theoretical and methodological trends of the day. Yet, there is another, more important reason why such a volume is necessary now, ‘today’, of all days, and another reason why this will serve as more than just another update on the discipline. Today, we face some of the greatest environmental challenges in global history. Understanding the damage being done by communities, large and small, and the varied ethics and efforts contributing to its repair is of vital importance. For these reasons, environmental anthropology today is different and arguably more critical than ever before. This volume thus poses the question and raises the challenge: What can increasing the emphasis on the environment in environmental anthropology, along with the science of its problems and the theoretical and methodological tools of anthropological practice do to aid conservation efforts, policy initiatives, and our overall understanding of how to survive, culturally and physically, as citizens of the planet?

The phenomena of urbanization and climate change interact with the growing number of older people living in cities. One of the effects of climate change is an increased riverine flooding hazard, and when floods occur this has a severe impact on human lives and comes with vast economic losses. Flood resilience management procedures should be supported by a combination of complex social and environmental vulnerability assessments. Therefore, new methodologies and tools should be developed for this purpose. One way to achieve such inclusive procedures is by incorporating a social vulnerability evaluation methodology for environmental and flood resilience assessment. These are illustrated for application in the Polish city of Wrocław. Socio-environmental vulnerability mapping, based on spatial analyses using the poverty risk index, data on the ageing population, as well as the distribution of the areas vulnerable to floods, was conducted with use of a location intelligence system combining Geographic Information System (GIS) and Business Intelligence (BI) tools. The new methodology allows for the identification of areas populated by social groups that are particularly vulnerable to the negative effects of flooding.

from the article: Abstract Based on a review of recent literature, this paper addresses the question of how urban planners can steer urban environmental quality, given the fact that it is multidimensional in character, is assessed largely in subjective terms and varies across time. The paper explores three questions that are at the core of planning and designing cities: ‘quality of what?’, ‘quality for whom?’ and ‘quality at what time?’ and illustrates the dilemmas that urban planners face in answering these questions. The three questions provide a novel framework that offers urban planners perspectives for action in finding their way out of the dilemmas identified. Rather than further detailing the exact nature of urban quality, these perspectives call for an approach to urban planning that is integrated, participative and adaptive. ; ; sustainable urban development; trade-offs; quality dimensions

Recently environmental education (EE) literature has been supportive of pluralistic rather than goal-oriented learning. Researchers argue that sustainability is not fixed but socially constructed and that sustainability issues should not be represented as indisputable targets. Countering this trend in environmental education research, this article argues that unsustainability should be treated as a concrete challenge that requires concrete solutions. The author will argue that there is a need for clear articulation of (1) what (un)sustainability is; (2) what are the key challenges of (un)sustainability; and (3) how the sustainability challenges can be meaningfully addressed. This article will outline a number of helpful frameworks that address obstacles to sustainability, ranging from population growth to unsustainable production and consumption practices. Solutions include investment in family planning to counter the effects of overpopulation, and alternative production frameworks, such as Cradle to Cradle that differs from the conventional frameworks. This article will conclude with the broader reflection that without goal-oriented critical learning explicitly providing sound models of sustainability, open learning may never permit transcendence from unsustainability. This article will develop a number of comprehensive frameworks targeted at solutions to sustainability issues both from ethical and practical perspectives.

In this article, we elaborate on the role of dialogical learning in identity formation in the context of environmental education. First, we distinguish this kind of learning from conditioning and reproductive learning. We also show that identity learning is not self-evident and we point out the role of emotions. Using Dialogical Self Theory, we then suggest that individuals do not have an “identity hierarchy” but a dialogical self that attaches meaning to experiences in both conscious and unconscious ways. We describe the learning process that enables the dialogical self to develop itself, and we elaborate on the characteristics of a good dialogue. We conclude with some remarks expanding room for a dialogue that would foster identity learning. https://doi.org/10.3390/resources5010011 https://www.linkedin.com/in/helenkopnina/

Adopted on the fifteenth anniversary of resolution 1325, Security Council resolution 2242 has recognized for the first time the substantial link between climate change and the “Women, Peace and Security” (WPS) framework. Despite this landmark resolution, the intersections of environmental factors, conflict and violence against women remain largely absent from the Security Council's WPS agenda. Competition over natural resources is generally understood as a driver of conflict. The risk of insecurity and conflict are further increased by environmental degradation and climate change. It is therefore clear that the environment and natural resources must be integrated into the WPS agenda. This should necessarily include a discussion of indigenous rights to land and the gender-related dimensions of environmental factors. Indigenous women are disproportionately affected by environmental degradation, caused by resource extraction and increasingly compounded by climatic changes. This in turn exacerbates other vulnerabilities, including sexual and gender-based violence and other forms of marginalization. This article argues, by reference to the situation in West Papua, that unfettered resource extraction not only amplifies vulnerabilities and exacerbates preexisting inequalities stemming from colonial times, it also gives rise to gendered consequences flowing from the damage wreaked on the natural environment and thus poses a danger to international peace and security. As such, the Security Council's failure to recognize the continuous struggle of women in indigenous and rural communities against extractive economies and climate change impact as a security risk forms a serious lacuna within its WPS agenda.

This article will briefly discuss the implications of the recognition of ecological justice in relation to environmental education (EE) and education for sustainable development (ESD). It is argued that the present conception of environment taught through EE and ESD negates the subjectivity of non-human species and ignores the ethical imperatives of ecological justice. Evocating environmental ethics, major directions integrating ecological justice into EE and ESD are proposed.

Repeat victimization has been widely studied from the perspective of environmental criminology for several decades. During this period, criminologists have identified a set of repeat victimization premises that are observed for many crimes; however, it is unknown whether these premises are also valid for cybercrime. In this study we rely on more than 9 million Zone-H data records from 2010 to 2017 to test whether these premises apply for the cybercrime of website defacement. We show that the phenomenon of repeat victimization is also observed in defaced cyber places (i.e. websites). In particular, we found that repeats contributed little to crime rates, that repeats occurred even several years after the original incident, that they were committed disproportionately by prolific offenders, and that few offenders returned to victimize previous targets. The results suggest that some traditional premises of repeat victimization may also be valid for understanding cybercrime events such as website defacement, implying that environmental criminology theories also constitute a useful framework for cybercrime analysis. The implications of these results in terms of criminological theory, cybercrime prevention, and the limitations derived from the use of Zone-H data are discussed.
