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.

Abstract Australia is a major immigration country and immigrants currently represent around 28% of the total population. The aim of this research is to understand the long-term consequences of this immigration and, particularly, how migrants respond to opportunities within the country after arriving through the process of subsequent (internal) migration. The focus is on major immigrant groups in Australia, including persons born in the United Kingdom, New Zealand, China and India, and how their patterns differ from persons born in Australia. To conduct this analysis, we have gathered data for a 35-year period based on quinquennial census data. We also obtained birthplace-specific mortality data for constructing multiregional life tables for the immigrant populations. Subsequent migration is important for understanding population redistribution, and the relative attractiveness of destinations within host countries. Our results highlight the importance of subsequent migration and the diversity of migration behaviours amongst different immigrant groups in the context of overall declines in internal migration since 1981.

Contemporary Reality

Melanesia's urban population tripled from a mere 7 percent of the region's total population in 1955 to 20 percent by 1985. The recency and magnitude of this development and the absence of any established forms of urban living in the region's precolonial history virtually rules out natural population growth as the principal cause behind this process of rapid urbanization and suggests massive internal population mobility as the most likely cause. The overall picture conveyed by the Melanesian mobility literature, however, emphasizes rural-based circular mobility as the predominant form of population mobility in the region. Seeking to reconcile this contrast, this article argues that much of the alleged continued predominance of circular mobility owes more to its underlying operationalizations, ways of measurement, and theoretical conceptualizations than reflects contemporary reality. This argument is substantiated by an analysis of recent developments in Vanuatu mobility set in the local and historical conditions of migration from the island of Paama. It is demonstrated how specific structural transformations on the island and in urban areas throughout this century were not only conducive to a change from temporary to long-term or permanent rural absences, but how they also have emerged as the direct result of mobility, thus highlighting the latter's dialectical nature. Evidence for this mobility change is derived from a comparative analysis of lifetime mobility histories of urban and rural Paamese men and women.

Using Data

More than a third of the world's languages are currently classified as endangered and more than half are expected to go extinct by 2100. Strategies aimed at revitalizing endangered languages have been implemented in numerous countries, with varying degrees of success. Here, we develop a new model regarding language transmission by dividing the population into defined proficiency categories and dynamically quantifying transition rates between categories. The model can predict changes in proficiency levels over time and, ultimately, whether a given endangered language is on a long-term trajectory towards extinction or recovery. We calibrate the model using data from Wales and show that the model predicts that the Welsh language will thrive in the long term. We then apply the model to te reo Māori, the indigenous language of New Zealand, as a case study. Initial conditions for this model are estimated using New Zealand census data. We modify the model to describe a country, such as New Zealand, where the endangered language is associated with a particular subpopulation representing the indigenous people. We conclude that, with current learning rates, te reo Māori is on a pathway towards extinction, but identify strategies that could help restore it to an upward trajectory.

In this work, influence of geogrids on overall stabilization of railway tracks is studied numerically. It is expected that by geogrids implementation significant reduction in the downward propagation of stresses will be obtained, which consequently should assure more resilient long-term performance. In this first approach, however, only added value to the confinement level of the ballast layer is analysed, by evaluation of lateral deformations. A case study is related to a part of the Portuguese railway network. The track and the passing vehicle are modelled in commercial explicit dynamics software LS-DYNA. Firstly, the model is validated by comparison with experimental data. Then a fictitious scenario of the same track with a deteriorated region which is further rehabilitated by the geogrid placement is analysed. Different situations are compared in terms of lateral and vertical displacements at several levels, but for simplicity only rail deflections are shown here.

Abstract This study is a historical analysis of the education of youth ministers in the Anglican diocese of Sydney in the 1970s and 1980s. John Kidson ran the Youthworkers Course with the goal of educating professional, specialised youth ministers that could evangelise young people who were influenced by the counter-culture and increasingly disengaged from the church. Kidson used a distinctive educational model that emphasised relational outreach, transformative community, praxis, and the importance of the Bible. His goal was only partially met. He trained youth ministers that were able to communicate with and evangelise non-churched youth, but there were small numbers being trained, and few remained in youth ministry in the long-term. The Youthworkers Course and its strengths and weaknesses can be used as a case study for churches and colleges today as they consider the best way to educate youth ministers.

Transportion networks can have a profound influence on economic development and the distribution of population. A long-term comparative study of the influence that rail services exerted on urban growth reveals that the creation of a structured railway network in France, Portugal, and Spain intensified the depopulation of extensive rural areas, as more and more people moved to, and between, cities. Areas that were once relatively small and insignificant began to thrive when the railway reached them.

The Dynamic Adaptive Policy Pathways (DAPP) approach has successfully been used to manage uncertainties in large infrastructure projects. However, the viability of the DAPP approach for spatial planning in smaller municipal settings is not clear. This paper examines opportunities and constraints of using adaptive pathways approaches to help small municipalities plan for future sea-level rise. The methodology was based on developing a simplified DAPP-approach, which was tested in a multiple experimental case study of spatial planning projects in three municipalities in Sweden. The results show that the approach promoted vulnerability-based thinking among the end-users and generated new ideas on how to manage the uncertain long-term impacts of future sea-level rise. However, the increased understanding of uncertainties was used to justify static, rather than adaptive, solutions. This somewhat surprising outcome can be explained by perceived legal constraints, lack of experience of adaptive pathways, and unwillingness to prescribe actions that could prove difficult to enforce in the future. More research is needed to further understand at what planning phases dynamic policy pathway approaches work best and how current barriers in legislation, practices, mind-set, organization, and resources can be overcome.

The paper explores spatial dynamics of the level and the intensity of the concentration of population/settlements situated in the Pomoravlje area, during the post- Second World War period, including overall conditions of the territory and evolutional aspect of its developmental tendencies. By evaluating Census data from 1948-2011, the main focus had been set on population dynamics of the settlements of the Pomoravlje area, and its dependence with regards to geographic, hypsometric and locational aspects of the territory. Considering the population dynamics of settlements in this area, the core concentrations and directions of their movement over the 63-year period were separated. The aim is to determine the degree of territorial homogeneity/heterogeneity of population distribution, using Hoover index of concentration and index of population concentration, both examining the relation between population and the area in question, and Kant index of concentration which next to those, also includes vertical differentiation. Therefore, nucleuses of population concentration as the focal points of settlements? expansion had been formed, as well as the population regression of small, underdeveloped settlements.

Purpose This study examined caregiver perceptions of their child's language and literacy disorder as influenced by communications with their speech-language pathologist. Method The participants were 12 caregivers of 10 school-aged children with language and literacy disorders. Employing qualitative methods, a collective case study approach was utilized in which the caregiver(s) of each child represented one case. The data came from semistructured interviews, codes emerged directly from the caregivers' responses during the interviews, and multiple coding passes using ATLAS.ti software were made until themes were evident. These themes were then further validated by conducting clinical file reviews and follow-up interviews with the caregivers. Results Caregivers' comments focused on the types of information received or not received, as well as the clarity of the information. This included information regarding their child's diagnosis, the long-term consequences of their child's disorder, and the connection between language and reading. Although caregivers were adept at describing their child's difficulties and therapy goals/objectives, their comments indicated that they struggled to understand their child's disorder in a way that was meaningful to them and their child. Conclusions The findings showed the value caregivers place on receiving clear and timely diagnostic information, as well as the complexity associated with caregivers' understanding of language and literacy disorders. The findings are discussed in terms of changes that could be made in clinical practice to better support children with language and literacy disorders and their families.
