The central place system of the Thessaly region of Greece

The settlement system of Thessaly is examined within the framework provided by central place theory. The adoption of a systems approach to the research determines the organization of the work. Firstly, there is an analysis of the sectoral structure of the Greek economy with particular reference to retail trade. The importance of tertiary activity in the economy is indicated and the traditional nature of most Greek retailing is considered. Next, the physical, historical, economic and demographic background of Thessaly is described. The region consists of a fertile plain surrounded on all sides by mountains. The economy is dominated by agriculture and the secondary and tertiary sectors are strongly oriented to it. In the post-war period the population of the area has stagnated because of heavy rural emigration focussed primarily on Athens, The analysis of the settlement system then falls into three parts. The functional regions of Thessaly are identified by subjecting an interaction matrix of bus traffic flows to factor analysis. These describe the general structure of the settlement system and allow the subsequent detailed analysis of the settlement system of West Thessaly to be placed within a wider context. This detailed analysis is based primarily on data collected in the field. It consists of a study of the hierarchical and spatial structure of the system and the aggregate relationships between its components. A well developed hierarchical structure is found, and its historical evolution is examined. Following this, a study of consumer movements in West Thessaly is made which is based on data collected from questionnaires circulated in the region. The behaviour of the settlement system as revealed by this analysis accords closely with the structure of the system. A composite assessment of the settlement system is then made which relates its structure and behaviour to the theoretical framework of the research, and comparisons are made with other studies of settlement systems in-Greece. Finally, the Greek regional problem is examined, one element in which is the nature and role of the provincial settlement system, and the implications of this research for future planning strategies are outlined

What Does Place Marketing Mean in Practice? A Preliminary Content Analysis of North West England Place-Related Websites

Place marketing has been used widely as a strategy for improving the competitive image of a place. However, confusion over what place marketing is, difficulties of identifying which practices are part of a place marketing framework, and the unclear roles of stakeholders, are hindering the field's progress. Therefore, this exploratory study is concerned with identifying a range of place marketing practices, supported by the literature, that are implemented by place marketing actors. A preliminary content analysis of 49 web pages from place-related organisations in North West England was conducted, and Chi-Square tests for independence explored the relationships between practices and stakeholders. The results showed that top-down practices associated with planning, place promotions, image communication, and service offerings (retail, events) are more common than practices concerned with engaging a variety of stakeholders for the common good of a place. Chi-Square tests also showed disparities between place stakeholders, as visitors/tourists appear to have a larger effect in the implementation of place marketing practices than citizens and investors. Overall, the study contributes to a better understanding of how place marketing is implemented in practice. The results will be used for further exploration of the relationships between place marketing practices and place stakeholders

Progress towards identification of a pheromone of the asparagus beetle, Crioceris asparagi (Coleoptera; Chrysomelidae)

The asparagus beetle, Crioceris asparagi L. (Coleoptera; Chrysomelidae) has become a widespread pest of asparagus, Asparagus officinalis (asparagus). There are no known attractants for C. asparagi and much of its biology is unknown. Volatiles were collected from individual beetles and a candidate pheromone component was detected in collections from some individuals of the first generation but not the second. This compound elicited an electroantennographic response from C. asparagi and the mass spectrum indicated it is a 19-carbon hydrocarbon with four double bonds. Complete structural elucidation and synthesis are in progress

Improving Together: A National Framework for Quality and GP Clusters in Scotland

Improving together will complement the development of the Scottish national GP contract that sets out the role of GPs and their important contribution as clinical leaders and expert medical generalists working in a community setting. This framework will be reviewed by the Scottish Government and the Scottish General Practitioners Committee of the BMA on a periodic basis, attentive to feedback from those involved in delivering its intent. As such, it is a framework that will develop to its full potential over time, as elements of the transformation of primary care in Scotland create the capacity to do so

Northern Gannet foraging trip length increases with colony size and decreases with latitude

Density-dependent competition for food influences the foraging behaviour and demography of colonial animals, but how this influence varies across a species’ latitudinal range is poorly understood. Here we used satellite tracking from 21 Northern Gannet Morus bassanus colonies (39% of colonies worldwide, supporting 73% of the global population) during chick-rearing to test how foraging trip characteristics (distance and duration) covary with colony size (138–60 953 breeding pairs) and latitude across 89% of their latitudinal range (46.81–71.23° N). Tracking data for 1118 individuals showed that foraging trip duration and maximum distance both increased with square-root colony size. Foraging effort also varied between years for the same colony, consistent with a link to environmental variability. Trip duration and maximum distance also decreased with latitude, after controlling for colony size. Our results are consistent with density-dependent reduction in prey availability influencing colony size and reveal reduced competition at the poleward range margin. This provides a mechanism for rapid population growth at northern colonies and, therefore, a poleward shift in response to environmental change. Further work is required to understand when and how colonial animals deplete nearby prey, along with the positive and negative effects of social foraging behaviour
