Abstract Emergence of cities and road networks have characterised human activity and movement over millennia. However, this anthropogenic infrastructure does not develop in isolation, but is deeply embedded in the natural landscape, which strongly influences the resultant spatial patterns. Nevertheless, the precise impact that landscape has on the location, size and connectivity of cities is a long-standing, unresolved problem. To address this issue, we incorporate high-resolution topographic maps into a Turing-like pattern forming system, in which local reinforcement rules result in co-evolving centres of population and transport networks. Using Italy as a case study, we show that the model constrained solely by topography results in an emergent spatial pattern that is consistent with Zipf’s Law and comparable to the census data. Thus, we infer the natural landscape may play a dominant role in establishing the baseline macro-scale population pattern, that is then modified by higher-level historical, socio-economic or cultural factors.

Chronic disease burdens continue to rise in highly dense urban environments where clustering of type II diabetes mellitus, acute myocardial infarction, stroke, or any combination of these three conditions is occurring. Many individuals suffering from these conditions will require longer-term care and access to clinics which specialize in managing their illness. With Singapore as a case study, we utilized census data in an agent-modeling approach at an individual level to estimate prevalence in 2020 and found high-risk clusters with >14,000 type II diabetes mellitus cases and 2000–2500 estimated stroke cases. For comorbidities, 10% of those with type II diabetes mellitus had a past acute myocardial infarction episode, while 6% had a past stroke. The western region of Singapore had the highest number of high-risk individuals at 173,000 with at least one chronic condition, followed by the east at 169,000 and the north with the least at 137,000. Such estimates can assist in healthcare resource planning, which requires these spatial distributions for evidence-based policymaking and to investigate why such heterogeneities exist. The methodologies presented can be utilized within any urban setting where census data exists.

Following the July 22, 2011, Oslo bombing and shootings at the Utøya youth camp Norway became embroiled in a conflict over commemorative ethics. The memorial initially selected in an international contest, Memory Wound by Jonas Dahlgren, drew opposition from victims’ families and local residents for its severe impact on the natural landscape. Plans for installation were cancelled in 2017. This controversy, we submit, must be contextualized in relation to the Norwegian justice system’s handling of Anders Breivik, the perpetrator whose criminal proceedings were kept relatively secluded. We demonstrate how the design of Memory Wound and the suppression of Breivik’s publicity reflect a symbolic logic traceable to a national imaginary of Norwegian exceptionalism. By interpretively aligning the use of negative space in Memory Wound with the muting of Breivik as a media event, we investigate the prescriptive force of symbols to inculcate world views. Specifically, we attend to the foreclosure of “prosthetic memory,” which through media circulation allows people to engage with memory that is not primarily theirs. We acknowledge the possibility of empathy across difference that Landsberg ascribes to prosthetic memory; however, we insist that the circumstances under which solidarity might be rejected must be considered. With a dual case study, we offer a perspective on enduring assumptions about cultural identity and the rise of rightwing extremism in Northern Europe.

ABSTRACTThis paper proposes a methodology for quantifying the territorial impact on population distribution of the railway. The central hypothesis is that access to railway services provides the best-connected areas with a long-term comparative advantage over others that are less accessible. Carrying out a historical analysis and providing comparable data at the municipal level allows us to determine the extent to which the railway has fostered the concentration of population within its immediate surroundings. The case study presented here is that of Spain between 1900 and 2001, but the same methodology could equally be applied to any other country for which the required data are available. In this case, key data included a Geographic Information System with information about both the development of the railway network and census data relating to total population at the municipal level. The results obtained suggest the relevance of this methodology, which makes it possible to identify the periods and areas in which this influence was most significant.

The article considers the gender culture in the family, one of the most closed and local socio-cultural institutions. The relevance of this topic is determined by the anthropological turn in modern humanitarian knowledge, and the involvement of new data in scientific circulation, which is obtained as a result of the use of case-study semi-formalized techniques for interviewing respondents. Thus, on the basis of the interviews received, there are reconstructed contradictory forms of gender identity in a young married couple in Perm. The article presents the materials of the respondents’ interviews in the form of narratives consistently presenting the key stages of the relationship. Gradually, the narrative’s characters begin to construct a gender identity in a new cultural institution – their own family. There can be seen a conflict between the characters’ symbolic self-identity and their real practices. The man takes a dominant role in the beginning of the relationship. He objectifies the woman and alone decides when to start the relationship. Then the situation changes. The man’s dominant role is replaced with a passive one. The initiative goes to the woman, who repeats the man’s behavior. At the same time, it turns out that in everyday life, the respondents fill the roles of the husband and wife with special content. The wife’s role includes the mother’s behavior towards her husband, and the husband’s role includes the child’s behavior towards his wife. The family is an inverse patriarchal type of relationship. The woman has a dominant role, but identifies herself as an obedient wife.

As e-government plays an increasingly dominant role in modern public administrative management, its pervasive influence on organizations and individuals is apparent. It is, therefore, timely and relevant to examine e-governance—the fundamental mission of e-government. By adopting a stakeholder perspective, this study approaches the topic of e-governance in e-government from the three critical aspects of stakeholder management: (1) identification of stakeholders; (2) recognition of differing interests among stakeholders; and (3) how an organization caters to and furthers these interests. Findings from the case study point to the importance of (1) discarding the traditional preference for controls to develop instead a proactive attitude towards the identification of all relevant collaborators; (2) conducting cautious assessments of the technological restrictions underlying IT-transformed public services to map out the boundary for devising and implementing control and collaboration mechanisms in the system; and (3) developing strategies to align stakeholder interests so that participation in e-government can be self-governing.

This paper explores the use of functional benefits transfer to forecast the effects of waste sites on property values. The results of a meta-analysis of hedonic studies of waste sites are coupled with spatial analysis techniques to produce estimates of the effects of toxic contamination in Areas of Concern (AOCs) in the U.S. Great Lakes. Based on U.S. Census data for median home values, the methods used here suggest that approximately S5.2 billion (2005 dollars) have been lost in residential property values surrounding twenty-three of the AOCs. This compares to estimates that place the cost of remediation of all U.S. AOCs at up to $4.5 billion (2005 dollars). The case study also identifies issues surrounding the use of a meta-analysis with hedonic property value studies to support functional transfer.

The dominant form of group work in the Church of England is educational and directive. An investigation was carried out to determine whether other forms of group work could be valuable for the Church in addition to this approach. The same group of nine members, members of two Church of England parishes in the North of England, were involved in 12 sessions of group work, four sessions of each of the three types of group structure, in order for them to report their individual reactions to each type. An Interpretive Phenomenological Analysis (IPA) showed that all three kinds of groups drew attention to four principle areas of comment. In all these kinds of groups, belonging, safety, enrichment and personalvalidation, with each one of the three groups scoring more highly than the other two on one or other of these dimensions. No group showed itself as more directly educational than the others, showing that, for church educational purposes, a range of group structures maybe used as actual learning comes from the experience of group membership itself. Using the qualitative research model of IPA, an investigation was carried out into the principal themes emerging from members’ self-reports concerning their experiences of the three different group structures, revealing four value constructs – belonging or alienation, safety or danger, enrichment or impoverishment and validation or rejection – which played a dominant role in all three kinds of groups. Taken together, each of the three group structures gave a different degree of prominence to each of the four evaluative constructs so that each of the three was shown to be particularly relevant for, and associated with, a particular area of experiential learning.Die onderrig van Anglikane – ’n ondersoek na groepwerk in die Kerk van Engeland: ’n gevallestudie. Die belangrikste vorm van groepwerk in die Kerk van Engeland is opvoedkundig en rigtinggewend van aard. ’n Ondersoek is gedoen na die waarde van bykomende metodes van groepwerk. Dieselfde groep van nege lede uit twee gemeentes in die Noorde van Engeland, was by die 12 groepwerksessies betrokke – vier sessies vir elk van die drie tipes groepstrukture – om hulle in staat te stel om hulle onderskeie reaksies op elkeen van die tipes groepstrukture te rapporteer. ’n Interpretiewe fenomenologiese analise het aangetoon dat al drie tipes groepstrukture die soeklig op vier hoofkenmerke laat val het, naamlik om te behoort, veiligheid, verryking en bevestigingvan eiewaarde. By elke groep het een of meer van hierdie kenmerke swaarder geweeg as by die ander twee groepe. Geeneen van die groepe het opvoedkundig meer as die ander uitgestaan nie, wat bewys dat ’n reeks groepstrukture vir kerklike opvoedkundige doeleindes gebruik kan word, aangesien leer in wese uit die ervaring van die groeplede self kom. Met behulp van die kwalitatiewe navorsingsmodel van die interpretiewe fenomenologiese analise is ondersoek ingestel na die hooftemas soos blyk uit die lede se individuele verslae ten opsigte van hulle ervaring van die drie verskillende groepstrukture. Die verslae het vier waardekonsepte openbaar wat ’n dominante rol in al drie tipes groepe gespeel het, naamlik om te behoort of te vervreem, veiligheid of gevaar, verryking of verarming, en bevestiging van eiewaarde of verwerping. Samevattend blyk dat die drie groepstrukture elkeen ’n ander graad van prominensie aan die vier verskillende waardekonsepte toeken sodat elke groep spesifiek relevant is vir en geassosieer word met ’n spesifieke area van ervaringsleer.

This paper presents a case study of the village of Mrkovi in the Bay of Kotor, Montenegro, showing the importance of landscape identification and assessment in planning the revitalization and development of Mediterranean rural settlements. The research revealed the methods of identification and evaluation of different landscape types. Moreover, it showed how such an approach could considerably contribute to the preservation of the space’s identity and quality by taking into account the existing characteristics of the space or the relationship between cultural and natural heritage. The identification of the landscape types was followed by the evaluation of individual elements and assessment of vulnerability in relation to the space’s natural, cultural, and visual quality. The first step in the process of preserving the elements that contribute to the landscape’s identity was the spatial identification of the cultural pattern of traditional terraces with drystone walls. The results of analysis indicate a high risk of degradation of the basic landscape value. The effects of future interventions in the space, especially the planned construction of a tourist resort, can be mitigated if they comply with the guidelines related to the rational use of the space and delimitation of the construction zones. This paper points out the importance of a responsible attitude and planned approach regarding the cultural and natural landscape of Mediterranean rural settlements.
