While self-report of overall quality of life has been widely examined, there are no studies that explore the impact of the relative importance people give to the various categories of their quality of life. Therefore, with a quantitative methodology and a co-relational transverse design, we analyze differences in the assessment when the importance given to each category is evaluated. Participants were 530 students from the city of Antofagasta in the North of Chile, aged between 15 and 18 years. They were from subsidized, public secondary schools and private and state universities in the city who were assessed using the KIDSCREEN-27 questionnaire. Results: Differences were found in the assessment of categories when results were analyzed based on gender and age and when incorporating an assessment of importance. Even when the results were not conclusive, there was evidence of a need to incorporate an importance variable when assessing quality of life.

The Brazilian Water Resources Policy (Law 9433/1997) establishes participatory and decentralized management, involving civil society, water users and governmental bodies, with the basin committees as the basis of this process. Fifteen years after its implementation, it is possible to perceive accomplishments, but, at the same time, there are some difficulties in regards to the operation of the basin committees in the country. Considering the North Paraíba River Basin – which is completely included in the State of Paraíba, Northeastern Brazil, and presents great social and economic importance for the state – this article analyzes the process of formation, installation and functioning of its Basin Committee (CBH-PB), focusing on its composition, the reasons for the mobilization and demobilization of its members, the intra-relations between segments, and the inter-relations between the CBH-PB and other entities of the State Water Management System (the Water Executive Agency and the State Water Resources Council). The level of decentralization and the quality of participatory management (as it is being performed at the CBH-PB) are discussed and guidelines are suggested in order to allow greater effectiveness to the committee.

The present study deals with the statistical analysis of physico-chemical parameters and cyanophycean members of two pond water quality of Chidambaram, Cuddalore district (Tamil Nadu). The qualities of pond water were analyzed for six months. Eleven important parameters were included in statistical analysis. The qualities of pond water have been assessed by calculating mean, standard deviation and correlation coefficient. Correlation studies of hydrobiology with physico-chemical parameters revealed that the relationship between phytoplankton density in general and that of the specific groups are highly complex and often controlled by interactions of different factors. In the both pond water the correlation coefficient test revealed that cyanophycean members positively correlated with temperature, pH, CO2, alkalinity, hardness, nitrate, BOD and COD at 1 % and 5 % level significant, where as it is negatively correlated with acidity and dissolved oxygen. In the present study it can be concluded that the cyanophycean members are highly tolerant organisms. They prefer to grow at higher temperatures and in highly alkaline, BOD and COD waters. Hence they can with stand high levels of contaminated waters of Thillai Kali Kovil pond, when compared to Ilamiyakkinar Kovil pond.

As the demand for visual quality of environment increases, visual analysis therefore plays progressively important role in current urban landscape construction and management. Guided by the City Image theory, this paper presents a covered scene index “X” to describe the visibility of the target scene, and formulates a digital analysis model based on ArcGIS and 3D simulation. This method is applied to the viewpoint analysis from the East Daming Road of the North Bund to the Oriental Pearl in Shanghai and optimized solutions are proposed according to the results. It turns out that this simple and objective technique can serve as a good tool for the reference of urban landscape planning and management.

In order to assess the mortality and lethality rates of newborns in obstetric organizations of the North-Western Federal District in 2013–2019, a comparative analysis of official statistics data was carried out. It was found that in the North-Western Federal District in the period from 2013 to 2019, there was an almost annual decrease in newborn mortality rates. The overall decrease in mortality in maternity care organizations of the Federal District (from 2,5% to 1,9%) was mainly due to a decrease in mortality in obstetric hospitals of the first and second levels (respectively from 3,2% to 1,2% and from 1,7% to 0,7%), while most children died in perinatal centers, where the mortality rate has not changed in recent years (2013 – 4,1%; 2019 – 4,0%). The study showed a decrease in mortality rates in the subjects of the Russian Federation that are part of the federal district, except for the city of St. Petersburg. The average hospital lethality rate of newborns in maternity care organizations of the North-Western Federal District during 2013–2019 was in the range of 1,9%–2,0%, did not change significantly and corresponded to the national average. However, the level of hospital lethality significantly differed in individual subjects of the district – in more than half of them, the level of hospital lethality exceeded the average, while in others it was significantly lower. Thus, the decrease in the mortality and lethality rates of newborns in maternity care organizations indicates an increase in the quality of medical care for children in the North-Western Federal District. dicates an increase in the quality of medical care for children in the North-Western Federal District.

Our extensive knowledge of Roman London is the result of over four decades of large-scale excavation. In the UK, the establishment and growth of professional archaeology since the 1970s, coupled with the funding provided by property developers since 1990 (Fulford & Holbrook 2015), has transformed our understanding of both urban and rural sites—and nowhere more so than London. A combination of intensive building development in the City of London and the world-leading technical quality of many of the excavations means that Londinium is now probably both the most extensively and best-excavated major town of the Roman world. Knowledge generated by these excavations, however, has not always been made available through publications as it should have been. Although there is an important archive in which the records of past projects are curated, how and where to publish results has been a long-running problem, especially for the excavations of the 1970s and 1980s where post-excavation work was often not properly funded or supported. One major project to publish a synthesis of work on such sites in Southwark, south of the Thames, did result in a series of important volumes (Sidell et al. 2002; Cowan 2003; Hammer 2003; Yule 2005; Cowan et al. 2009), but a programme designed to provide systematic coverage of such projects in the City of London, to the north of the river (Maloney 1990; Perring & Roskams 1991; Williams 1993; Davis et al. 1994), failed to produce one of the five volumes promised—that concerning the archaeology of the key eastern hill. We also lack any up-to-date synthesis, a problem only partly compensated for by Dominic Perring's (1991) popular overview and Wallace's (2014) in-depth analysis of the evidence for the period down to the Boudiccan revolt in AD 60/61.
