Qualitative Characteristics

In the present work, the analysis of the variability of quantitative and qualitative morphological traits of Japanese Camellia (Camellia japonica L.) varieties used in greenhouses of botanical institutions in Moscow is considered. The paper considers the following varieties: ‘Governor Mouton’, ‘Madame Lebois’, ‘Covina’, ‘Bella Toscana’, ‘Bonomiana’, ‘Alba Simplex’, ‘Lavinia Maggi’, ‘ Silver Waves ’,‘ Doncklaeri ’. To assess the variability, 10 characters were selected, six of which describe the leaf (leaf blade length, leaf blade width, leaf ovality index, leaf blade base shape, leaf blade apex shape, leaf blade shape) and four – flowers (corolla color, flower diameter, degree of terry and aroma). The variability of quantitative characteristics was assessed by determining the confidence intervals method and calculating the coefficients of variation. The variability of qualitative features was assessed by establishing modalities and determining modes. It is noted that, in terms of quantitative and qualitative characteristics, weak variability is observed in most cases. Thus, the studied varieties of Japanese camellia have stable features that characterize the flower and leaf blade. Keywords: CAMELLIA JAPONICA, JAPANESE CAMELLIA, VARIABILITY, VARIETIES

Growth Of Seedlings

The morphological parameters of the maternal trees growth, seed progeny and seedlings, and the value of the fluctuating asymmetry (FA) of the leaves of adult plants under urban influence were estimated. Urban oak groves have a low growth rate of shoots. Rural and suburban oak groves are characterized by an increase in the shoot. The coefficients of variation (Cv) in the length and width of leaf blades are generally low; only for 1 territory near urban radius and experiencing the influence of industrial enterprises, the Cv of the length of the leaf blade is 29.3% and the width of the leaf blade - 30.4%. FA for all oak forests, with the exception of Chizhovskoe tract (0.056), not exceed 0.04, thus, they are resistant to the anthropogenic factor. The average growth of seedlings is 13-14 cm. The coefficient of variation for shoot length for most groups of seedlings exceeds 30%. The suburban seedlings have the largest shoot thickness and exceed 0.3 cm. Among urban seedlings, the oak population in the most distant from the city (middle circle), is close to this indicator. The areas of the lowest emission load of pollutants coincide with the forest areas of the city.

Qualitative Characteristics

In 1695, Jan Teofil Plater and his wife Aleksandra founded a hospital for six impoverished nobles in Vilnius. Situated near the newly built church of the Ascension and the convent of the Congregation of Mission in the Subocz suburb beyond the city walls, this hospital was the first and, until the end of the eighteenth century, the only charitable institution providing care for individuals of particular social status. The article, based on the hospital’s registry book and other sources, examines the quantitative, as well as qualitative characteristics of the institution’s clientele, such as its fluctuations in size, its social composition, and the causes of its inmates’ impoverishment. The research revealed that, despite the demand for care, the overseers managed to maintain a stable number of inmates, rarely admitting more than one or two persons every year, and thus ensuring a steady operation of the hospital (see table 1). However, in contrast with other charitable institutions in Vilnius, the clientele of the Congregation of Mission hospital changed frequently because of expulsions (39.6 percent of all cases) and inmates leaving the hospital on their own initiative (20.1 percent) already in the first year of their stay. The mortality of inmates (27.8 percent) affected the size and turnover of the clientele to a much lesser extent than observed in other hospitals. Although there are no reliable data on the inmates’ age and health, such statistics show that they probably were younger and healthier than the clients of other charitable institutions in Vilnius. Moreover, the Congregation of Mission hospital’s inmates differed from the clients of other institutions in respect of social composition. Impoverished petty nobles, originating mainly from the districts of Lida and Oszmiana, constituted the majority (56.25 percent) of the hospital’s inmates whose social status is noted in the registry book (62.5 percent). The nobles became clients of the Congregation of Mission hospital either because of old age, disability, as well as other accidental causes, or because of increased social vulnerability outside mutual aid networks, comprised of family members, kin or neighbours. The article argues that the foundation of a hospital designated to provide care primarily for impoverished nobles shows that the poverty of nobles was recognized by contemporaries as a social problem that should be tackled.

This paper uses a typological approach as a tool to establish an analytical framework from a physical perspective to understand ‘place‘ and to identify key spatial characteristics that could adapt to local needs to deliver socio-cultural sustainability. Six representative housing types with their spaces and uses that were introduced in a historic neighborhood in Beijing, China are selected as case studies. Their morphological characteristics at the building, open space and neighborhood scales are examined, and typological transformations among the cases in terms of the degree of spatial continuity are identified. The paper proposes an analytical framework consisting of fifteen indicators to assess socio-cultural sustainability at the different morphological scales (building, open space and block/neighborhood) of the residents of the six cases. The score of changes from its original design is brought into calculations of continuities of spatial characteristics, which present the transitions and transformations of morphological characteristics in relation to adaptation of local needs and uses. The analysis results show that the spatial characteristics were changed when political-socioeconomic ideologies changed, and local needs and uses were transformed to follow these mutations, and finally, the methods of use in different morphological scales mostly differed from historical norms. Although the continuities of spatial characteristics were significantly changed, they are positively and continually accommodating the transformations and transitions of local needs and uses. On the other hand, the invariant spatial characteristics are important, which last despite transformation of the city development and changing of political-social-economic ideologies, and could be maintained for future development to enhance sociocultural sustainability.

Qualitative Characteristics

The results of the analysis and assessment of long-term changes in the qualitative characteristics of the Oka River runoff are presented. To analyze the temporal dynamics of the variability of the average annual and maximum concentrations of pollutants in the runoff of the Oka River, we used long-term observational data on typical pollutants for the period 1984-2019. The assessment of the state of the quality of surface waters of the Oka River was carried out according to the values of the concentrations of pollutants in the upper, middle and lower reaches of the river. The dynamics of the main pollutants of the following indicators is considered: ammonium nitrogen, oil products, copper and zinc compounds and easily oxidized organic substances. It was found that in the upper reaches of the river (according to observations of the Oka – Orel city) the main pollutants are ammonium nitrogen and copper compounds, the average annual concentrations of which respectively increased to 9 values. A similar situation was observed downstream of the river (the Oka River – Kaluga city). As a result of the analysis, it was revealed that more noticeable changes in the concentration of pollutants are observed in the section of the river from the city of Murom to the city of Dzerzhinsk. Near the city of Murom, the content of oil products in the water sharply increases. From the beginning of the study period (1984) and until 1995, the average annual concentration varied from 5 to 30 values, and the maximum concentration in the year in creased to 87 values. After 2000, the content of oil products in water dropped sharply and the average annual value did not exceed 3 values, and the maximum concentration was 4-6 values. The paper analyzes the frequency of cases of exceeding the maximum permissible concentrations of pollutants in the Oka River in the mouth of the river. There was a high repeatability of the content of copper compounds in water, which varied from 70 to 88%. The frequency of cases of excess of easily oxidized organic matter in the mouth of the Oka River varied from 64 to 74%. Relatively low, although stable, the repeatability of the content of oil products in water remained, which ranged from 23 to 42%.

Purpose The purpose of this paper is to explore a citizen-centered tool for public accountability, the popular report (PR). Elaborating on previous studies and on content analysis of a sample of municipalities in the USA, this paper aims to identify the qualitative characteristics and content elements that PR should have to serve as a legitimation tool. Design/methodology/approach The study adopts a mixed methodology. After the analysis of previous studies on PR and best practices in US municipalities, a list of content elements and qualitative characteristics of PR is compared with results emerging from the content analysis of PR published by of a sample of municipalities in the USA. Findings The analysis reveals that the PR should embed information about the government’s sources of revenues and taxes, expenditures, cost of government services, liveability and governance of the city. Research limitations/implications The paper offers new knowledge on reporting centered on citizens, framing the analysis in the legitimacy theory. Even though the research relates only to the US context, the results may assist standard setters in preparing guidelines for local governments to communicate financial data to citizens and stimulate further research in other contexts. Practical implications The results may encourage local governments to prepare a PR suitable to discharge accountability and gain legitimation. Originality/value This study is the first to discuss the PR within a theoretical framework, in this case, legitimacy theory. Moreover, a further novelty lays in the analysis carried out on the PRs published by US municipalities in order to derive qualitative characteristics and content elements with which the PR should comply.

Amaranthus L. is genus of C4 dicotyledonous herbaceous plants comprising approximately 70 species, with three subgenera, which contains both cultivated and wild types, where cultivated ones are used for food grains, leafy vegetables, potential forages and ornamentals. Grain amaranth are pseudocereals from three species domesticated in North and South America and are notable for containing high amount of protein and minerals and balanced amino acid in their small seeds. Genetic diversity analysis of amaranths is important for development of core set of germplasm with widely diverse population and effective utilization of plant genetic resources. In this study, we evaluated a germplasm collection of 260 amaranth accessions from United State Department of Agriculture (USDA) and 33 accessions from Seed Savers’ Exchange (SSE). We evaluated morphological traits like blade pigmentation, blade shape, petiole pigmentation, branching index, flower color, stem color, inflorescence density, inflorescence shape, terminal inflorescence attitude, plant height and yield characteristics across all 293 accessions. We compared clustering within the USDA and SSE collection and across both collections. Data analysis of morphological data showed significant difference of petiole pigmentation, stem color, blade pigmentation, blade shape and flower color across different clusters of accessions of USDA unlike among different clusters of SSE where we found significant difference of only blade pigmentation, blade shape and flower color. The relationship depicted by neighbor-joining dendogram using the morphological markers was consistent with some but not all of the differences observed between species. Some divisions were found between cultivated and weedy amaranths that was substantiated by morphological characteristics but no separation of South and Central American species was observed. Substantial phenotypic plasticity limits the use of morphological analysis for phylogenetic analysis but does show that important morphological traits such as inflorescence type and plant architecture can cross species boundaries. Similarly, color variants for leaves, flowers and seeds are not exclusive to one cluster in our study nor to one species and can be used widely for breeding any of the cultigens, but not to species identification. Our findings will help in germplasm conservation of grain amaranths and facilitate in this crop’s improvement. It will also help on developing effective breeding programs involving different plant characteristics and morphological traits of Amaranths.
