In the era of space travel, ecology has continued to gain relevance as the science of the ‘spaceship Earth’. In this context, it can be said to have a mission, which is to understand the complex network of the life-support systems that keep biospheric processes operating in a way suitable to sustaining living organisms and their environment (Odum & Sarmiento 1997). With the realization that ecology, in the broad sense, provides the means to understand the mechanics of nature, scholars are using ecological understanding at the interfaces of disciplines to: (1) prevent and reverse the demise of biodiversity in marine and terrestrial ecoregions (conservation biology), (2) reduce impacts of population pressure on the resource base of people (ecological anthropology), (3) establish more parsimonious economic activities to ensure optimum yields for the long term (ecological economics), (4) plan for an appropriately-equitable and socially-integrative sustainable development (environmental design), (5) restore degraded ecosystems and landscapes (restoration ecology), and (6) model hypothetical future scenarios where predictions from ecological theory may prove valuable for the future of mankind (environmental planning).

Landscapes of the Tobol-Ishim interfluve were not stable in the Holocene and varied from forests and drowned floodplains at the beginning of the V and III millennia BC to steppificated territories with a lowered water level at the beginning of the Atlantic Period and in the middle of the Subboreal Period, which determined the main types of economic activities, one of them was fishing. Changes in hydrological regime of water bodies influenced the methods of fishing, including the use of different traps. Thus, in the Neolithic, when the water level decreased, the location of settlements in the system river-creek-lake (for example, Mergen 6), a large number of fish bones, bone harpoons, fishing spears, fishing tackles for catching pike and a total absence of plummets were indicative of individual fishing for large fish and, perhaps, of stop net fishery, which was facilitated by a decrease in the width of watercourses and tombolos. Stop net (stake net) fishery led to a settled lifestyle of the population, collective activities and the emergence of long-term settlements with deep foundation pits of dwellings. When the water level in rivers and lakes increased and floods became more frequent, the life support system changed, the population began to develop coasts more widely, its mobility increased, and they started to build framed above-ground dwellings. Following those changes, biconic, cigar-shaped, and corniculate plummets emerged in the Tobol River Basin and on the adjacent western and north-western territories in the III and early II millennium BC. When the water level was high, it was efficient to fish using traps, seines and, probably, nets, although the latter could also be used in drive hunting for shedding geese and ducks. Subrectangular plummets with one or two ties for fastening, and disk-shaped plummets with a tie in the center had been prevailing since the beginning of the II millennium BC; they existed until the first third of the I millennium BC. This period, the transition time from the Bronze Age to the Early Iron Age, is characterized by the absence of clay plummets, while there are large accumulations of fish scales and bones in the settlement layers. We can suppose that the population of that time (local Late Bronze Age population, mixed with northern migrants who made utensils with cross ornamentation) switched from net fishing to stop net fishing.

How do parents cope when their child is ill or dying, when he or she experiences constant pain or suffering? What do parents think of the contributions that medical professionals make to the care of their chronically or terminally ill child? Is it possible for a parent to love a child so much that the child is wished dead? The purpose of this paper is to explore those questions and aspects of the care of chronically or terminally ill children using Mourning Dove’s portrayal of one family’s attempt to care for their ill daughter. A play written by Canadian playwright Emil Sher, Mourning Dove is based on the case of Saskatchewan wheat farmer Robert Latimer who killed his 12 year old daughter Tracy who suffered with cerebral palsy and lived in tremendous pain. Rather than focusing on the medical or legal aspects of the care of a chronically ill child, the play offers a glimpse into how a family copes with the care of such a child and the effects the child’s illness has on a family. Reading and examination of non-medical literature, such as Mourning Dove, therefore serve as a useful means for medical professionals to better understand how illness affects and is responded to by patients and their families. This understanding is a prerequisite for them to be able to provide complete care of children with chronic or terminal illnesses and their families. Nuutila L, Salanterä S.

Any economic activity carried out by an organization, can generate a wide range of environmental implications. Particularly important, must be considered the activities that have a significant negative effect on the environment, meaning those which pollute. Being known the harmful effects of pollution on the human health, the paper presents two models of utmost importance, one of the material environment-economy interactions balance and the other of the material flows between environmental factors and socio-economic activities. The study of these models enable specific conditions that must be satisfied for the economic processes friendly coexist to the environment for long term, meaning to have a minimal impact in that the residues resulting from the economic activity of the organization to be as less harmful to the environment.

Pessimism looms large all over. COVID-19 has been projected as worse than the Great Depression of 1930. Everyday analyst and agency reports are diving into new bottoms of a fall-down in economic activities. Indian economy, however, has a slightly different story to tell at this hour of crisis. The silver lining for the Indian economy comes from a steep fall in the crude oil prices from around $70 per barrel to a record 18 years low of $22 per barrel. This windfall gain can, to some extent, offset the direct losses due to COVID-19. At the same time, dreams like a $5 trillion economy no longer look even a remote possibility. This article takes stock of the likely impact of COVID-19 on the Indian economy in the short term and the long term. A decision-tree approach has been adopted for doing the projections.

Abstract Me & My Wishes are person-centered videos of long term care residents (ages 65-95) living with dementia discussing their preferences for care including end-of-life (EOL) medical intervention. We evaluated the congruence of six EOL treatment preferences between the residents’ personal videos, medical records (e.g. advance directive), and surveys of family (n= 49) and staff (n=37; 118 responses) knowledge of their preferences. Results were highly discordant. Treatments with the most discordance when comparing videos to comparison groups were IV fluids (medical record, 57.1%) and life support (family, 69.4%; staff, 82.2%). Residents reported EOL treatments were considered acceptable if they were temporary, would relieve suffering, or enabled a return to baseline health. These caveats may lead to discordance if they are not conveyed to family or staff. Our findings highlight the need for conversations among residents living with dementia and their caregivers to improve understanding, congruence and adherence of resident EOL preferences.

Uranium Tailings

Uranium tailings (UT) are formed as a byproduct of uranium mining and are of potential risk to living organisms. In the present study, we sought to identify potential biomarkers associated with chronic exposure to low dose rate γ radiation originating from UT. We exposed C57BL/6J mice to 30, 100, or 250 μGy/h of gamma radiation originating from UT samples. Nine animals were included in each treatment group. We observed that the liver central vein was significantly enlarged in mice exposed to dose rates of 100 and 250 μGy/h, when compared with nonirradiated controls. Using proteomic techniques, we identified 18 proteins that were differentially expressed (by a factor of at least 2.5-fold) in exposed animals, when compared with controls. We chose glycine N-methyltransferase (GNMT), glutathione S-transferase A3 (GSTA3), and nucleophosmin (NPM) for further investigations. Our data showed that GNMT (at 100 and 250 μGy/h) and NPM (at 250 μGy/h) were up-regulated, and GSTA3 was down-regulated in all of the irradiated groups, indicating that their expression is modulated by chronic gamma radiation exposure. GNMT, GSTA3, and NPM may therefore prove useful as biomarkers of gamma radiation exposure associated with UT. The mechanisms underlying those changes need to be further studied.

Economic Use

The conservation of many species depends on sustainable economic activities that shape their habitats. The economic use of these anthropogenic habitats may change quickly owing to world trade globalization, market reorientations, price volatility or shifts in subsidy policies. The recent financial crisis has produced a global impact on the world economy. How this may have affected the use of habitats beneficial to biodiversity has not yet been documented. However, consequences could be particularly acute for species sensitive to climate change, jeopardizing long-term conservation efforts.
