The author offers mapping and geoecological analysis of the Russian Federation regions presence in the state program “Environmental Protection”. The unequal distribution of the program’s targets and activities in different regions is revealed. A considerable number of relevant environmental problems for several mentioned regions have not been reflected in the program. It is important to increase the area of specially protected natural areas for a significant number of subjects of the Russian Federation. The status “part of the territory occupied by specially protected natural territories of Federal value in the total area of the subject of the Russian Federation” is recommended to be assigned all regions of Russia. Identification and elimination of objects of accumulated environmental damage that threat to the Volga river is relevant, at least for all the regions in which the Volga flows. Not all regions with a high level of air pollution and/or large masses of air pollutants have the indicator “reduction of total emissions for the reporting year”. It is necessary to increase the Program of measures for the protection of rare and endangered species of plants and to expand the list of regions in which it is planned to protect rare and endangered species of animals.

In this chapter, stories of young men and women who live in basti (slum settlements) near one of the most affluent neighborhoods in Pune, India, are analyzed. It is argued that the basti youth’s “capacity to aspire” is not just an individual trait or a psychological ability. Rather, their aspirations are shaped by their caste identities, structural conditions of poverty, their narrative capacity, their schooling in vernacular language, and the prestige accorded to speakers of English language in urban India. The stories of the basti youth are characterized as dispossessed because they are shaped by and connected to the possessions of the dominant class who live nearby and the unequal structural conditions of their basti. These stories reveal that globalization, by and large, has exacerbated the structural inequality in the slum settlements in Pune. Structural inequality refers to a system that creates and perpetuates an unequal distribution of material and psychological privileges .

Lithium is a critical element for the modern society due to its uses in various industrial sectors. Despite its unequal distribution in the environment, Li occurrence in Romania was scarcely studied. In this study a versatile measurement method using ICP-MS technique was optimized for the determination of Li from various matrixes. Water, soil, and plant samples were collected from two important karst areas in the Dobrogea and Banat regions, Romania. The Li content was analyzed together with other macro- and microelement contents to find the relationship between the concentration of elements and their effect on the plants’ Li uptake. In Dobrogea region, half of the studied waters had high Li concentration, ranging between 3.00 and 12.2 μg/L in the case of water and between 0.88 and 11.1 mg/kg DW in the case of plants, while the Li content in the soil samples were slightly comparable (from 9.85 to 11.3 mg/kg DW). In the Banat region, the concentration of Li was lower than in Dobrogea (1.40–1.46 μg/L in water, 6.50–9.12 mg/kg DW in soil, and 0.19–0.45 mg/kg DW in plants). Despite the high Li contents in soil, the Li was mostly unavailable for plants uptake and bioaccumulation.

Abstract In this paper we deal with a specific subset of direct speech markers, to which little or no attention has been given so far: the expressions which codify the ending of the direct speech (“marcatori conclusivi del discorso diretto”). We analyse these markers in Old Italian texts, comparing them with their Latin and, in some cases, Old French equivalents. In the introduction (§1), we take into account various general issues related to ancient texts, namely the practice of spoken-word reading and the lack of systematic punctuation marking that helps text segmentation. After that (§2), we classify the different strategies ancient writers had at their disposal to signal that a direct speech is over, hence that what follows has to be interpreted as the narrator voice; the markers are organized in a range from most explicit to most implicit (disse > quando ebbe detto > a queste parole > allora > [Ø]). Thereafter (§3), we focus on two specific markers, the participial marker (detto questo) and the “connector + finite tense” marker (quando ebbe detto questo) in a corpus of nine texts. Though these two markers are roughly synonymic, their occurrence is not uniform among the analysed texts. The explanation of their unequal distribution is that they belong to different discourse traditions (Diskurstraditionen): “quando + finite tense” is a typical expression attested in Romance narrations (the so-called “quand-Satz”), whereas detto questo appears to be dependent on Latin tradition.

Traditional economic system has brought important negative implications regarding environmental development, as well as an unequal distribution of wealth, which has led to ecological disasters and population imbalances. Considering the existence of unequal opportunities and access to resources in a global economy, it would be relevant to study the interrelations between the concepts of Sustainability and Corporate Social Responsibility (CSR). Global and multifactorial issues require the review of fieldworks and their connections. From this perspective, the present research aims to analyze the relationships between the concepts of Corporate Social Responsibility and Sustainability in order to understand the advances of current scientific production and future lines of research. In this way, there is a considerable increase of interest in this line of research, highlighting García-Sánchez as the most productive author, Business, Management and Accounting as the most studied topic, and Sustainability Switzerland as the most productive journal. The country with the most publications and citations is the United States, and the most productive institution is Universidad de Salamanca. Future lines of research should focus on the social dimension and its possibilities in the field of Circular Economy. Finally, a line of research is proposed that also includes the proposals from the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals.

AbstractHumans sometimes cooperate to mutual advantage, and sometimes exploit one another. In industrialised societies, the prevalence of exploitation, in the form of crime, is related to the distribution of economic resources: more unequal societies tend to have higher crime, as well as lower social trust. We created a model of cooperation and exploitation to explore why this should be. Distinctively, our model features a desperation threshold, a level of resources below which it is extremely damaging to fall. Agents do not belong to fixed types, but condition their behaviour on their current resource level and the behaviour in the population around them. We show that the optimal action for individuals who are close to the desperation threshold is to exploit others. This remains true even in the presence of severe and probable punishment for exploitation, since successful exploitation is the quickest route out of desperation, whereas being punished does not make already desperate states much worse. Simulated populations with a sufficiently unequal distribution of resources rapidly evolve an equilibrium of low trust and zero cooperation: desperate individuals try to exploit, and non-desperate individuals avoid interaction altogether. Making the distribution of resources more equal or increasing social mobility is generally effective in producing a high cooperation, high trust equilibrium; increasing punishment severity is not.

Objective: Understanding the socioeconomic inequalities in dietary intake is crucial when addressing the socioeconomic gradient in obesity rates and non-communicable diseases. We aimed to systematically assess the association between socioeconomic position (SEP) and dietary intake in Chile. Design: We searched for peer-reviewed and grey literature from inception until 31st December 2019 in PubMed, Scopus, PsycINFO, Web of Sciences and LILACS databases. Observational studies published in English and Spanish, reporting the comparison of at least one dietary factor between at least two groups of different SEP in the general Chilean population, were selected. Two researchers independently conducted data searches, screening, extraction and assessed study quality using an adaptation of the Newcastle Ottawa Quality Assessment Scale. Results: Twenty-one articles (from 18 studies) were included. Study quality was considered low, medium, and high for 24, 52 and 24% of articles, respectively. Moderate-to-large associations indicated lower intake of fruit and vegetables, dairy products and fish/seafood and higher pulses consumption among adults of lower SEP. Variable evidence of association was found for energy intake and macronutrients, in both children and adults. Conclusions: Our findings highlight some socioeconomic inequalities in diets in Chile, evidencing an overall less healthy food consumption among the lower SEP groups. New policies to reduce these inequalities should tackle the unequal distribution of factors affecting healthy eating among the lower SEP groups. These findings also provide important insights for developing strategies to reduce dietary inequalities in Chile and other countries that have undergone similar nutritional transitions.

Background and Objective. The number of new entrants to higher medical schools of Kazakhstan increased by 1.6 times from 2007 to 2012. However, it is not known how it will affect the shortage of human resources for health. Additionally, human resources for health in rural areas of Kazakhstan are 4 times scarcer than in urban areas. The aim of the present study was to investigate the intentions of students toward their professional future and readiness to work in rural areas, as well as to determine the causes for dropping out from medical schools. Material and Methods. A cross-sectional survey was conducted in 2 medical universities in Almaty during the academic year 2011–2012. The study sample included medical students and interns. In total, 2388 students participated in the survey. The survey tool was an anonymous questionnaire. Results. The students of the first years of studies compared with those of later years of studies were more optimistic about the profession and had more intentions to work in the medical field. Only 8% of the students reported a wish to work in rural localities. On the other hand, 4% of the students did not plan to pursue the profession. On the average, every third medical student dropped out on his/her own request. Conclusions. Associations between intentions to work according to the profession and the year of studies, faculty, and residence area before enrolling in a medical school were documented. The majority of the students who came from rural areas preferred to stay and look for work in a city, which might contribute to an unequal distribution of physicians across the country.
