This paper develops a multi-objective optimisation model to compute resource allocation,shelter assignment and routing options to evacuate late evacuees from affected areas to shelters.Three bushfire scenarios are analysed to incorporate constraints of restricted time-window and potential road disruptions.Capacity and number of rescue vehicles and shelters are other constraints that are identical in all scenarios.The proposed mathematical model is solved by ?-constraint approach.Objective functions are simultaneously optimised to maximise the total number of evacuees and assigned rescue vehicles and shelters.We argue that this model provides a scenario-based decision-making platform to aid minimise resource utilisation and maximise coverage of late evacuees.

Japan’s inbound tourism numbers have been steadily rising in the past decade due to active promotion, easing of visa regulations, rapidly developing Asian economies and the depreciation of the Japanese Yen. The government’s goal is welcoming 40 million foreigners yearly by 2020, and leading them to rural destinations. There is a concern whether rural destinations in Japan are prepared for this sudden surge of tourists. The plans to bring masses to rural destinations implies a steady supply of tourism service, but the ageing and shrinking population of Japan together with the migration towards cities, leave some destinations without a key resource: workforce. This paper tries to understand the current situation of such rural, isolated communities, and whether they have the capacity to develop and expand the tourism industry. The case study was carried out on Ojika, an island destination in Nagasaki Prefecture. Several visits to the destination, participant observation and structured as well as unstructured interviews with stakeholders provide the primary data for the research. Through interviews with town officials, businesses and residents, different approaches to the demographic problems are introduced. The results show that the tourism development strategies cannot concentrate only on the strictly tourism industry elements of the destination but have to look at the community and infrastructure too, in this case, the labor market. The demographic change in society can put a limitation on development, thus counter measurements have to be considered and included in the tourism strategy. Further research is needed on less remote destinations, where there is a land-connection with another settlement, and whether a “commute based workforce” can ease the problem or by raising the costs of labour, a different, feasibility problem arises in the accommodations.

Indonesia has received external debt as an external source of finance to fill in the investment-saving gap in achieving economic growth to improve social welfare. Despite Indonesian economy is able to recover to some extent, based on Bank Indonesia (2018), Indonesia’s external debt at the end of Q2/2018 still amounted to USD 355,7 billion; consisting of government and central bank external debt of USD 179.7 billion, as well as private sector (including state-owned enterprises) external debt of USD 176.0 billion. Therefore, this study aims to examine the trend and impact of external debt on economic growth in the context of Indonesia’s economy. If external debt is found to lead to debt trap, or already in the condition of growth-led debt, its benefits for economic development should be reviewed properly and government policies regarding external debt need to be redesigned. This study is a qualitative research in the form of case study of External Debt and its critical impact in Indonesia. Through observation, data comparison and literature study, it is found that external debt of Indonesia has been dominated by US Dollar and Japanese Yen, which assumed to cause surge in debt repayment.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
