This article summarizes the protocol applied to analyse the spatial consequences of diverse regional plans included in the General Spatial Planning of Catalonia (GSPC) municipalities since 1985. The main aims of the GSPC were to achieve a more balanced distribution of population, avoiding Barcelona metropolitan region congestion, coastal overcrowding and mountain areas depopulation, and to improve mobility infrastructures and social welfare. The methodology used was based on factor analysis that reduced 30 socioeconomic and geographic variables provided by different sources into a smaller number of common factors. Afterwards a non-hierarchical clustering was employed to simplify the analysis of dynamics. The six first common factors retained in the model explained the 82.6% of total variance. After labelling them, six clusters were mapped to describe the most important dynamics: urban sprawl, urbanalization, depopulation, reterritorialization and coastalization. Finally, some socio-environmental consequences of such dynamics are discussed. 相似文献

This paper focuses on the emergence in the 20th century of a fishing industry based on northern shrimp (Pandalus borealis) in Norway, Sweden, Denmark and Iceland. Development in these countries exhibited noteworthy common features that are examined and compared in this paper, which emphasizes the intellectual, political and industrial conditions that facilitated the expansion of the fishing fleets and processing industries. The diffusion of knowledge and technology was a necessary condition for the industry's establishment, both at a national and an inter-Nordic level. Central to these transfers of knowledge was the interaction between scientists and fisheries experts and fishermen and industrialists. 相似文献

Archaeological deposits are often complex and illustrative of an intricate interplay between geogenic and anthropogenic inputs and formation processes. Even for those archaeologists—particularly prehistorians—who consider the basic principles of natural stratigraphy to excavate their sites, they nonetheless typically underutilize the observations and data available at the microstratigraphic level. The technique of soil micromorphology—or archaeological micromorphology as referred to throughout this paper—has seen an astounding increase in its use to answer archaeological questions and archaeological sediments in the last decades. However, we consider that this tool is still quite underutilized and not as mainstream as other techniques. In this paper, we briefly reflect on what can be some of the causes underlying this situation and how we (that is, both producers and consumers of micromorphology data) can go about to change it. The main idea is that we need to establish a better and more approachable way to present micromorphological results and be better at integrating them with the macroscopic archaeological data and research questions. 相似文献

The use of stable carbon isotopic analysis of bone apatite to reconstruct prehistoric diets is hindered by the possibility of diagenetic alteration of carbonate during burial. We examine apatite preservation in Classic Period Maya skeletal remains from Dos Pilas, Guatemala, using Fourier transform infrared spectroscopy (FTIR). We use weight % CO2evolved from apatite, FTIR carbonate/phosphate absorbance ratios, phosphate peak splitting crystallinity indices, fluoride peaks, and stable oxygen isotopic ratios to identify diagenetic change in apatite chemistry. Isotopically light carbon taken up from burial soil is adequately removed from most Dos Pilas bone by treatment with dilute acetic acid, but more severe alteration cannot be reversed by standard preparation methods. Infrared criteria identify recrystallized apatite in a subset of Dos Pilas burials, that is accompanied by isotopic exchange, and that no longer preserves biogenic δ13C. These results illustrate that comparatively recent bone may be diagenetically altered and demonstrate a need for systematic evaluation of mineral integrity in all archaeological bone prior to interpreting paleodiets with apatite δ13C. 相似文献

Research ethics are not the favourite subject of most undergraduate geography students. However, in the light of increasing mixed-methods research, as well as research using geocodes, it is necessary to train students in the field of ethics. Experiential learning is an approach to teaching that is potentially suitable for teaching ethics. The aim of this article is to discuss how the experiential learning process in a course on Ethics & GPS-tracking contributed to the ethical awareness of third-year undergraduate geography students. We conducted a qualitative study in which we held four focus group discussions with two cohorts of students (2016 and 2017). We explored the students’ views on the learning environment in relation to ethics in GPS-based and mixed-methods research. Our findings show how an informal learning environment and collaborative learning in a small group contributed to deep understanding of research ethics. These aspects of the learning environment are tied to an ethical framework that consists of three dimensions: (1) the ethics of collaborative research between staff and students; (2) the ethics of privacy raised by the geo-technology adopted in this research case study; and (3) the ethics of the research process with respect to informed consent and data storage. 相似文献

Greek papyrus letters preserve not only instances of the replacement of the dative case; they also show the use of the dative instead of the accusative case as direct object and disjoint infinitival subject. This interchange is mostly found in epistolary phrases, namely the salutation formula (?σπ?ζομα? σε) and the initial (ε?χομα? σε ?για?νειν) and final (?ρρ?σθα? σε ε?χομαι) health wishes. The phonetic similarity of the pronouns might have created the circumstances for case confusion. Contamination of the constructions reflects the difficulties of the scribes to construct conservative epistolary phrases and, thereby, diachronic phraseological variation might reflect language change. In salutation formulas, the use of a dative Addressee could be explained by analogical overextension from the category of communication verbs taking a dative complement. The decline of the accusative and infinitive construction might be one of the reasons why the accusative disjoint infinitival subject is replaced by the dative case in health wishes. 相似文献

This article analyses new trends in the assessment of Russian–Ukrainian relations by representatives of the Russian elites in the late 1990s. It sees a discussion of the historic roots of Ukrainian separatism in the Russian media and attempts to identify the origins of the ‘Russian national homeland’ outside Kyiv Rus as the first steps towards a revision of traditional Russian perceptions of Russian–Ukrainian relations. The article argues that the new trends have become particularly visible following the signing of the Russian–Ukrainian inter‐state treaty in May 1997, which it regards as an important landmark in Russia's acceptance of the independence of Ukraine. 相似文献
