English. The Public Green Space (PGS) in urban zones is a major interest in the sustainable development, both regarding environment and the quality of life of their users. The present study constitutes a first research which is interested in the PGS of the Urban district of Marrakesh (UDM) to have a basis of scientific data on these spaces and to help taking decision and environmental planning of it. It aims at (i) the study of the diversity of the ornamental flora (ii) and the analysis of the structure and the distribution of these PGS. So, the prospecting concerned 50 PGS distributed on 5 districts of the UDM. The results showed a diversity of ornamental flora which contains 297 vascular species, distributed in 212 genera and 88 families. 77 % of species are exotic. This specific richness is dominated by 12 families which contain 142 species distributed in 85 genera. The frequency, the origin and the biological type of these species are much diversified. The study of the structure highlighted 4 types of PGS that differ by their size and their function. The analysis of the floral affinity of the PGS-UDM revealed 13 groups which distinguish by their floral compositions. Consequently, the PGS-UDM contributes deeply to the preservation and the increase of the floral diversity and improvement of the esthetic quality of the city of Marrakesh.Fraçais. En milieu urbain, l’espace vert public (EVP) constitue un enjeu majeur du développement durable, tant en matière d’environnement que de qualité de vie de leurs usagers. La présente étude présente une première recherche sur les EVP de la ville de Marrakech permettant de disposer d’une base de données scientifiques sur ces EVP qui va aider à la prise de décision et de planification environnementale de la ville. Elle vise (i) l’étude de la diversité de la flore ornementale (ii) et l’analyse de la structure et la répartition spatiale de ces EVP. La prospection a concerné 50 EVP urbains répartis sur les 5 arrondissements de la ville. Les résultats ont montré une diversité de la flore ornementale qui s’élève à 297 espèces vasculaires, réparties en 212 genres et 88 familles et dont 77 % des espèces sont exotiques. Cette richesse spécifique est dominée par 12 familles qui détiennent 142 espèces réparties en 85 genres. La fréquence, l’origine et le type biologique des espèces sont très diversifiés. L’étude de la structure a fait ressortir 4 types d’EVP qui diffèrent par leur taille et leur fonction. L’analyse de l’affinité floristique des EVP-CUM a fait apparaître 13 groupes qui se distinguent par leurs compositions floristiques. En conséquence, les EVP de la ville contribuent vivement à la conservation et l’accroissement de la diversité floristique et à l’amélioration de la qualité esthétique de la ville de Marrakech.

The opportunity to use the tangible resources of our planet – water, air, subterranean depths – secure the existence of our civilization. Despite the existence of private property and the division of ownership of tangible resources between natural and legal persons, the resources required for life are objectively determined by the very life form. Any living creature needs air, water and subterranean depths. They are the common value of the mankind. The right to live in a favourable environment is recognized as the basic right of each individual, of each member of the public. A significant aspect is the high quality environment, which includes specific standards and requirements for the quality of air, water and subterranean depths. This is necessary in order to ensure the legal protection of the environment, balancing the rights of private owners and society as a whole. The protection of the environment is the subject matter of the legal framework. The key challenge for the protection of the environment is to find an opportunity to balance the economic development and the sustainable development of the environment, which is why the greatest attention should be allocated to the questions that relate to the prevention and compensation for the damage caused to the environment. Keywords: environment, damage caused to the environment, sustainable development

The settlement is a very important topic and is widely discussed in all countries. This study is a study that discusses the topic of settlement using the literature review method. In this study, we will discuss several articles related to housing and try to compare with the conditions of settlements in Indonesia. The findings of this study are that there are two aspects of empirical research that are not found to be running optimally in Indonesia, namely: aspects of consumption patterns and urban and environmental planning. Meanwhile, the empirical condition that is under the conditions of housing in Indonesia is the limited quality of human resources and types of housing in Indonesia as well as aspects of the interaction between the public sector, the interaction of the private sector to increase settlement growth.

Integrated approaches in landscape management are often seen as the way forward to provide solutions for complex heritage problems that are related to policy, climate change, tourism, environmental planning and involving the public. This has led to a range of interdisciplinary and multidisciplinary projects aiming to add value to disciplinary approaches and gain new insights. Although interdisciplinarity is a promising research approach, there are many obstacles that may affect the quality of the project outcomes, slow down the overall organisation or create substantive errors. This raises therefore the question: is integration always a good idea? In this paper, I will show the complexity of cultural-historical landscapes and examine interdisciplinary approaches for their value as framework for historical landscapes. The role of historical assessments methods in landscape design is discussed. Finally, the example of two historical gardens and the process of their restoration and conservation will demonstrate how interdisciplinary and disciplinary approaches are related to each other in the garden design process.

AbstractThe strengthening of social cohesion, the globalization and the opening of the market to free competition, the expanding of the public – private partnership and the sustainable development are the main questions which arise today about the future of services of general interest. The current economic and financial crisis recalls that the main role of the services of general interest lies in ensuring the social and territorial cohesion. At the same time, the crisis has a significant impact on the public sector due to the pressure on public finances and it is essential to make every effort possible in order to keep providing these services and improve their quality. The upcoming accession of Romania to the European Union requires precise criteria for guaranteeing the performance and quality of public services of general interest and, in particular, the development of network industries and the link between these elements is a prerequisite for facilitating the integration, increasing citizens welfare and achieving in a short time the community rules and standards. The role of services of general interest is the sustainable development of a territory and their contribution in maintaining the balance between environment and society, exploiting the available resources in a particular plan, fighting against social exclusion and isolation. Overall, the man has an important role, he can transform the environment, because he is considered an integral part thereof, subject only to maintaining the balance between himself and the other components of the environment; at the same time, he must accept his role as a stabilizing factor in his relationship with nature. Services of general interest in a region should positively influence the life of people in order to achieve the long-term development vision by transforming the region’s functioning of institutions. Sustainable development means recognizing that economy, environment and social welfare are interdependent namely that affecting the environment in terms of quality will sooner or later have a negative influence on economic development and the quality of life of each one of us. The human component is an essential urban mobility, and every type of public service must be carried out in a planned system in terms of territory. A responsible demographic capable of long-term strategies for rational use of resources, ensures sustainability planning. Sustainability does not imply an imposed proactive strategy. If an area has resources, a vigorous and enterprising demographic system, fair and profitable exchanges with the outside, it is sustainable, thus it can evolve without outside intervention.

Abstract. Comments sections under news articles have become popular spaces for audience members to oppose the mainstream media’s perspective on political issues by expressing alternative views. This kind of challenge to mainstream discourses is a necessary element of proper deliberation. However, due to heuristic information processing and the public concern about disinformation online, readers of comments sections may be inherently skeptical about user comments that counter the views of mainstream media. Consequently, commenters with alternative views may participate in discussions from a position of disadvantage because their contributions are scrutinized particularly critically. Nevertheless, this effect has hitherto not been empirically established. To address this gap, a multifactorial, between-subjects experimental study ( N = 166) was conducted that investigated how participants assess the credibility and argument quality of media-dissonant user comments relative to media-congruent user comments. The findings revealed that media-dissonant user comments are, indeed, disadvantaged in online discussions, as they are assessed as less credible and more poorly argued than media-congruent user comments. Moreover, the findings showed that the higher the participants’ level of media trust, the worse the assessment of media-dissonant user comments relative to media-congruent user comments. Normative implications and avenues for future research are discussed.

Using different cross-country data sets and simple econometric techniques we study public attitudes towards the police. More positive attitudes are more likely to emerge in the countries that have better functioning democratic institutions, less prone to corruption but enjoy more transparent and accountable police activity. This has a stronger impact on the public opinion (trust and attitudes) than objective crime rates or density of policemen. Citizens tend to trust more in those (policemen) with whom they share common values and can have some control over. The latter is a function of democracy. In authoritarian countries — “police states” — this tendency may not work directly. When we move from semi-authoritarian countries to openly authoritarian ones the trust in the police measured by surveys can also rise. As a result, the trust appears to be U-shaped along the quality of government axis. This phenomenon can be explained with two simple facts. First, publicly spread information concerning police activity in authoritarian countries is strongly controlled; second, the police itself is better controlled by authoritarian regimes which are afraid of dangerous (for them) erosion of this institution.
