Nakhon Si Thammarat Old Town Community dated a thousand years old from four eras of settlement development. The community is located on an ancient beach ridge that stands until the present day. It also has an image of a community that is unique to any city. Today the community is rapidly expanding, so the importance of the old town’s various elements has been diminished. The research objectives are to analyze Nakhon Si Thammarat Old Town Community’s image and landscape and provide suggestions to preserve and develop the community’s image. The methodology is theoretical concepts of the image of the city, urban landscape, historic urban landscape, and urban conservation, including field surveys to identify problems and the community’s awareness. Visual assessments and mapping were also undertaken. Based on the study, the urban conceptual framework emphasizes the five elements of physical perception, whereas the cultural landscape concept focuses on the physical perception of the community’s core components and sub-elements that express specificity of the district, including traditional custom, which is intangible culture and a landscape element as well.  The analysis of urban image reveals that Nakhon Si Thammarat Old Town Community consists of the path in the area with Ratchadamnoen Road, Karom Road and Pattanakarn Khukwang Road as the main routes, the edge of the community divided by natural boundaries, which are various rivers and by man-made boundaries, which are canals and the old city’s embankments, and the unique district, such as Tha Wang Community, Khaek Market Community, and Nakhon Si Thammarat Old Town. The node or activity center is, for example, business activities in Tha Wang Community, Khaek Market Community and Hua It Market Community, and the tourism activities in the old community area around Phra Mahathat Woramahawihan Temple. The prominent landmark from the past to the present is Phra Borommathat Stupda. In addition, the unique physical elements in the old town are groups of large trees. Suggestions on conservation and development are to create awareness of secondary routes to reduce congestion of the main roads and connect to other attractions; to develop the old town’s border from four eras for clearer perception; to promote the main activities within each district; and to have measures to control the height, billboards, old buildings’ styles, and new buildings representing each district’s uniqueness that will not obscure the perception of the community’s landmarks.

AbstractRailway systems provide pivotal support to modern societies, making their efficiency and robustness important to ensure. However, these systems are susceptible to disruptions and delays, leading to accumulating economic damage. The large spatial scale of delay spreading typically make it difficult to distinguish which regions will ultimately affected from an initial disruption, creating uncertainty for risk assessment. In this paper, we identify geographical structures that reflect how delay spreads through railway networks. We do so by proposing a graph-based, hybrid schedule and empirical-based model for delay propagation and apply spectral clustering. We apply the model to four European railway systems: the Netherlands, Germany, Switzerland and Italy. We characterize these geographical delay structures in the railway systems of these countries and interpret these regions in terms of delay severity and how dynamically disconnected they are from the rest. The method also allows us to point out important differences between these countries’ railway systems. For practitioners, such geographical characterization of railways provides natural boundaries for local decision-making structures and risk assessment.

Sociohydrology is a recent effort to integrate coupled human-water systems to understand the dynamics and co-evolution of the system in a holistic sense. However, due to the complexity and uncertainty involved in coupled human-water systems, the feedbacks and interactions are inherently difficult to model. Part of this complexity is due to the multi-scale nature across space and time at which different hydrologic and social processes occur and the varying scale at which data is available. This systematic review seeks to comprehensively collect those documents that conduct analysis within the sociohydrology framework to quantify the spatial-temporal scale(s) and the types of variables and datasets that were used. Overall, a majority of sociohydrology studies reviewed were primarily published in hydrological journals and contain more established hydrological, rather than social, models. The spatial extents varied by political and natural boundaries with the most common being cities and watersheds. Temporal extents also varied from event-based to millennial timescales where decadal and yearly were the most common. In addition to this, current limitations of sociohydrology research, notably the absence of an interdisciplinary unity, future directions, and implications for scholars doing sociohydrology are discussed.

National Nature Park “Pyryatynsky” is a valuable reserve of flora and vegetation of the Left-Bank Dnipro. The extensive hydrological network of the Udai River and the wide representation within this nature reserve of floodplain reservoirs are the reason for the high diversity of plant communities of higher aquatic vegetation. In this article we classified the communities of order Callitricho-Batrachietalia in National nature park "Pyryatynskyi" and identify the features of their syntaxonomic and ecological differentiation. Fragmentary and non-comlete information about this type of vegetation are existed in literature, however, without geobotanical releves and detailed characteristics of the structure of phytoceonoses, synecology and synchorology. All obtained results based on original field data. In total, 22 geobotanical releves were performed during the period 2010–2017. The description of communities was carried out within their natural boundaries. Treatment of fitosociological data was performed with the JUICE software package. The nomenclature of syntaxons was consistent with the International Code of Phytosociological Nomenclature (ICFN).The order of Callitricho-Batrachietalia on the territory of NPP "Pyriatynsky" is represented by alliance Batrachion aquatilis Gehu 1961 and 4 associations (Batrachietum aquatilis Gehu 1961, Potameto perfoliati–Batrachietum circinati Sauer 1937, Hottonietum palustris Sauer 1947, Veronico beccabungae–Callitrichetum stagnalis (Oberdorfer 1957) Th. Müller 1962). This is first prodrome of order Callitricho-Batrachietalia for territory of National Nature Park “Pyryatynskyi”. The communities of this syntaxon occupy small areas and have a limited distribution in the region. Most of them are rare and vulnerable to changes in environmental conditions. Monitoring of their structure, chorology and dynamics is an important task to maintain and preserve the species and coenotic diversity of NPP "Pyryatynsky".

The authors have revealed the features of summer warming in different sectors of the Russian Arctic zone in the modern period and the near future. In connection with the considered features of the summer warming within 1991—2018, the researchers present a unique analysis of the inter-decade distribution of trends in the characteristics of the natural zones surface (vegetation index, total evapotranspiration, surface temperature, albedo). Changes in climatic conditions provide prerequisites for a change in the spectral characteristics of landscape zones, especially in the central sector of the Russian Arctic zone.

The emergent political arena of the late eighteenth century, and the literary one that preceded it, were claimed to be based upon a functional dichotomy between a private sphere of emotive ties and associations, and a “public sphere” of rational criticism (Habermas, 1962). This categorical distinction, however, scantily registered the emergence of a corollary affective economy in this period, which redefined social, political, and physical spaces according to their emotional content, or lack thereof. This article focuses on the rise of emotional language, its spatial configurations, and its dissemination during the late German Enlightenment in three thematic contexts: the “popular Enlightenment” (Volksaufklärung) and its emphasis on the enhancement of literacy among the lower classes to achieve emotional refinement; the visual representation of domestic emotional scenarios in the context of the Franco-German cultural exchange surrounding the French Revolution; and the emergence of “homeland” (Heimat) as an increasingly ubiquitous emotion-bound metaphor in the nationalization of space toward the century's end. These contexts reveal major shifts in the cultural dynamics of space and emotion in this period: first, the reaffirmation of emotion as a culturally viable interpretive mode, set against earlier concerted attempts to suppress or control it; second, the osmosis between private and public that enabled emotional protocols to transgress supposedly natural boundaries of class, status, and gender across society, and establish new contacts between exclusive and excluded communities; and last, the article shows how the spatial imaginary that emerged in the second half of the eighteenth century—despite its reliance on older dispositions regarding space in German culture—deployed emotional vocabularies for engendering new forms of sociability, which went on to became central determinants of Germanness in the early nineteenth century.

Abstract Background In the context of an outbreak the natural boundaries of islands can allow for control of movements between populations. We estimate the risk of introduction of COVID-19 to each of the Hebridean islands situated off the west coast of mainland Scotland due to individual movements, and explore control strategies to mitigate this risk.Methods We use a combination of real human mobility data and census data to generate seasonally varying patterns of human movements amongst the Hebrides and from elsewhere. We consider three distinct periods: each of summer and winter 2019, illustrating a year prior to the pandemic, and summer 2020 illustrating a "pandemic summer". Movements during these periods serve as input to simulate COVID-19 transmission from the mainland to the archipelago in a stochastic meta-population model allowing us to explore the impact of seasonal variations on the risk of introduction and the effectiveness of non-pharmaceutical interventions.Results Despite strong seasonality in movement patterns, partly driven by tourism, for islands closely connected to the mainland there is evidence of substantial risk of disease introduction even over winter. In summer, when the risk is the highest, some islands can delay the introduction of COVID-19 by over six weeks, i.e. beyond the summer holiday period, through a 70% reduction of movements. Conclusion A high introduction risk in winter will be of particular concern if COVID-19 becomes a seasonal respiratory infection affecting temperate areas in winter concomitantly with other seasonal infections such as flu.For some islands, control of movements in peak summer tourist season has the potential for delaying the introduction risk beyond the summer holiday period, i.e. beyond a period of high mobility of people, potentially inducing a risk for rapid spread. Such measures would be particularly relevant in the occurrence of a variant escaping the vaccine given the current progress of the vaccine roll-out. However, such restrictions must be balanced against indirect negative economic impacts that might result.

The study was aimed to obtain the concept of indigenous forest according to the Meyah ethnic community, the Meyah ethnic community's perception of indigenous forest, and the factors that influence the use of the indigenous forest by the Meyah ethnic community. Descriptive methods with observation and interview techniques are used in this study. Respondents were selected by purposive sampling, as many as 30 families. The results show that the concept of indigenous forest according to the Meyah ethnic community is a forest area given by God the Creator of the Universe as human property rights to live for generations, reproduce and adapt to their environment, and utilize the resources in the forest. Ownership of indigenous forests is controlled by individuals or clan groups for generations in certain areas marked by natural boundaries. The first activity in utilizing the forest as a source of life was by clearing land for houses and gardening as well as collecting forest products, which were used as the basis for determining the boundaries of land and forest rights. The Meyah ethnic community has a strong perception of indigenous forests, both perceptions of indigenous forest ownership, indigenous forest sustainability, and indigenous forest use. The factors that influence the Meyah ethnic community in the use of indigenous forests consist of a) determining factors, namely: customs and way of life about the forest; b) supporting factors, namely: livelihood and length of stay, and c) driving factors, namely: the role of traditional and religious leaders.
