The study provides information on the features of strategic management at water supply and sewerage enterprises, which consists of creating long-term strategies in various areas of the enterprise's activities. A resource-supplying enterprise is a complex multifunctional production and economic system that is aimed at providing the city's population with water supply and sanitation services, as well as focused on the interests of the consumer. It is possible to achieve the main goals of the enterprise only with the construction of long-term goals and assessment of development prospects. The study provides an analysis of the weaknesses and strengths in the course of the activities of the enterprise SUE "Vodokanal of St. Petersburg" and reflects its long-term goals and assesses the prospects for achieving these goals and objectives. Further, the article reflects the matrix of prospects for building complex strategies that allow you to evaluate and plan the activities of the water supply and sewerage enterprise. The article was prepared as part of the author's dissertation research. Strategic guidelines and, in particular, the matrix contains the main elements of the organization's activities, which include: the general direction of the enterprise's activity, interaction along the "consumer" – "enterprise" chain, production, social, environmental strategies of the organization's activities, investment and tariff strategies. In summary, the presented mechanism reflects the fact that the water supply and sewerage enterprise will develop in the direction of reducing the negative impact on the environment, the ways of innovative development of the enterprise, the enterprise also plans to receive investments from external sources and allocate internal financing for development and projects within the organization. Considerable attention will be paid to the development of production processes, i.e. reduce losses and costs, the most efficient use of enterprise resources, improve the quality of provided services. Special attention will be paid to the field of "working with consumers", which will improve communication between employees of the enterprise and direct subscribers of the organization. Thus, the water supply and sewerage enterprise has prospects in the development of its activities, but the beneficial development depends on external and internal factors and the correct construction of a system of strategic guidelines.

Jim Davie's essay on integrating nature conservation with the economic, social and political realities of Indonesia is as relevant to Australia as it is to developing nations. Although Davie makes this clear, it is a message that most Australians might overlook or choose to ignore. For too long Western nations have pursued the myth of nature conservation through reserves. We know that Australia's system of conservation reserves in neither representative nor viable in the long term. Conserving the continent's biodiversity requires a system of reserves and the environmentally sensitive management of the matrix within which the reserve system is embedded. Yet, Landcare and growing efforts by State forestry authorities aside, there is little evidence of environmentally sensitive management directed at conserving biodiversity on the vast expanse of urban, forestry, agricultural and pastoral lands throughout Australia. Moreover, it is by no means clear what the end result of establishing a comprehensive, adequate, and representative system of forest reserves throughout Australia will be. One concern is that the relevant authorities will adhere to the message of the myth and decide that with an "adequate" reserve system, management of forest biodiversity outside the reserves is less important or even unnecessary. If this eventuates, then the creation of a reserve system will actually have a negative impact on forest conservation.

Water Supply And Sanitation

Some ten years ago, South Africa's newly elected government inherited huge services backlogs with respect to access to water supply and sanitation. About 15 million people were without safe water supply and over 20 million without adequate sanitation services. Since then, the country has made remarkable progress with regard to accelerating the pace of services provision and restructuring and refocusing the entire water sector. Having ensured access to an additional population of over 10 million people, South Africa is well on track to wipe out the infrastructure backlog for basic water supply by 2008, exceeding the Millennium Development Goals (MDG) target. But first, with respect to sanitation for which the national target is universal access to a functioning facility by 2010, the picture is somewhat different. Second, substantial challenges remain in addressing historical inequalities in access to both water supply and sanitation, and in sustaining service provision over the long term.

Abstract For animals that tend to remain with their natal group rather than individually disperse, group sizes may become too large to benefit individual fitness. In such cases, group splitting (or fission) allows philopatric animals to form more optimal group sizes without sacrificing all familiar social relationships. Although permanent group splitting is observed in many mammals, it occurs relatively infrequently. Here, we use combined generalized modeling and machine learning approaches to provide a comprehensive examination of group splitting in a population of killer whales (Orcinus orca) that occurred over three decades. Fission occurred both along and across maternal lines, where animals dispersed in parallel with their closest maternal kin. Group splitting was more common: (1) in larger natal groups, (2) when the common maternal ancestor was no longer alive, and (3) among groups with greater substructuring. The death of a matriarch did not appear to immediately trigger splitting. Our data suggest intragroup competition for food, leadership experience and kinship are important factors that influence group splitting in this population. Our approach provides a foundation for future studies to examine the dynamics and consequences of matrilineal fission in killer whales and other taxa. Significance statement Group living among mammals often involves long-term social affiliation, strengthened by kinship and cooperative behaviours. As such, changes in group membership may have significant consequences for individuals’ fitness and a population’s genetic structure. Permanent group splitting is a complex and relatively rare phenomenon that has yet to be examined in detail in killer whales. In the context of a growing population, in which offspring of both sexes remain with their mothers for life, we provide the first in-depth examination of group splitting in killer whales, where splitting occurs both along and across maternal lines. We also undertake the first comprehensive assessment of how killer whale intragroup cohesion is influenced by both external and internal factors, including group structure, population and group demography, and resource abundance.

Abstract Background While a strong negative impact of unemployment on health has been established, the present research examined the lesser studied interplay of gender, social context and job loss on health trajectories. Methods Data from the German Socio-Economic Panel was used, which provided a representative sample of 6838 participants. Using latent growth modelling the effects of gender, social context (East vs. West Germans), unemployment (none, short-term or long-term), and their interactions were examined on health (single item measures of self-rated health and life satisfaction respectively). Results Social context in general significantly predicted the trajectories of self-rated health and life satisfaction. Most notably, data analysis revealed that West German women reported significantly lower baseline values of self-rated health following unemployment and did not recover to the levels of their East German counterparts. Only long-term, not short-term unemployment was related to lower baseline values of self-rated health, whereas, in relation to baseline values of life satisfaction, both types of unemployment had a similar negative effect. Conclusions In an economic crisis, individuals who already carry a higher burden, and not only those most directly affected economically, may show the greatest health effects.

BACKGROUND: China’s atmospheric PM2.5 pollution is serious, and PM2.5 exerts a negative impact on the human respiratory system, cardiovascular, and mental health, and even more serious health risk for the elderly with weak immunity. OBJECTIVE: This work aims to analyse the impacts of PM2.5 microenvironment exposure on the health of the elderly and provide corresponding countermeasures. METHODS: The survey subjects are 118 retired elderly people in the community. PM2.5 exposure concentrations are monitored in summer (June 10 ∼ July 10, 2019) and winter (November 25 ∼ December 25, 2019). RESULTS: The exposure concentration in winter is higher than that in summer, with statistical difference (P <  0.05). Under the impact of PM2.5 microenvironment exposure, smoking in the elderly can increase the concentration of PM2.5, and long-term exposure to PM2.5 in the elderly can cause mental health problems. CONCLUSION: Long-term exposure of the elderly to the PM2.5 microenvironment leads to physical diseases and even psychological problems, which requires attention.

AbstractPatients undergoing allogeneic stem cell transplantation (allo-SCT) are given a real chance of cure, but at the same time are confronted with a considerable risk of mortality and of severe long-term impediments. This narrative, non-systematic literature review aims to describe the supportive and palliative care needs of allo-SCT recipients, including long-term survivors or those relapsing or dying after transplantation. It also evaluates the feasibility and effectivity of integrating palliative care early in transplant procedures. In this appraisal of available literature, the main findings relate to symptoms like fatigue and psychological distress, which appear to be very common in the whole allo-SCT trajectory and might even persist many years post-transplantation. Chronic GvHD has a major negative impact on quality of life. Overall, there is a paucity of research on further issues in the context of allo-SCT, like the distress related to the frequently unpredictable post-transplant trajectory and prognosis, as well as the end-of-life phase. First randomized controlled results support the effectiveness of early integration of specialized palliative care expertise into transplant algorithms. Barriers to this implementation are discussed.

Climate change significantly affects water supply availability due to changes in the magnitude and seasonality of runoff and severe drought events. In the case of Korea, despite high water supply ratio, more populations have continued to suffer from restricted regional water supplies. Though Korea enacted the Long-Term Comprehensive Water Resources Plan, a field survey revealed that the regional government organizations limitedly utilized their drought-related data. These limitations present a need for a system that provides a more intuitive drought review, enabling a more prompt response. Thus, this study presents a rating curve for the available number of water intake days per flow, and reviews and calibrates the Soil and Water Assessment Tool (SWAT) model mediators, and found that the coefficient of determination, Nash–Sutcliffe efficiency (NSE), and percent bias (PBIAS) from 2007 to 2011 were at 0.92, 0.84, and 7.2%, respectively, which were “very good” levels. The flow recession curve was proposed after calculating the daily long-term flow and extracted the flow recession trends during days without precipitation. In addition, the SWAT model’s flow data enables the quantitative evaluations of the number of available water intake days without precipitation because of the high hit rate when comparing the available number of water intake days with the limited water supply period near the study watershed. Thus, this study can improve drought response and water resource management plans.
