The Impact

In aeronautics, hard landing is a critical condition as the aircraft approaches the runway with a vertical velocity that exceeds 2 m/s. Beyond that level, the energy that should be then absorbed by the whole structure could cause severe damage to the landing gear and the whole structural system. This document reports on the set-up, execution and results of a preparatory test campaign performed on a small landing gear (LG) demonstrator instrumented with a fibre-optic sensor system. In detail, a leaf spring landing gear was released from a drop tower to detect information about the strain state and the related acceleration history of some specific components during the impact. The objective of the present research is the development of a method for assessing whether hard landing is experienced, and to what extent. Deformation measurements through an integrated Fibre-Bragg grating (FBG) network allowed retrieving impact velocity by a devoted, original algorithm. The proposed preliminary methodology is the base for assessing a more complex procedure to correlate structural response to the energy entering the structure during the touchdown event.

The increasing number of accidents involving chemical spills demands development of not only feasible emergency strategies, but also a consistent framework to protect the environment and prevent accidents. This can be possible only by a sound understanding of the environmental impact of spills and their potential long-term effects. Furthermore, the impact assessment of chemical spills can not be done disregarding the spatial-temporal pattern of previous exposures reciprocally influenced by both chemical and environmental properties. In this context, the thesis proposes a general framework to quantify the cumulative effects of chemical spills at any given point of a certain area based on a “present” history of exposure coupled with chemical and environmental properties designated as relevant to predict possible pictures o f future exposure and estimate in advance potential alarming levels of pollution. To achieve this purpose, the following objectives are set up. The first objective is to develop a four-dimensional model to simulate a single-spill event based on certain assumptions about chemical and soil characteristics. The second objective is to develop an algorithm to assess the cumulative effects of chemical spills on a selected area using the model for a single-spill event while taking into account the effects of those spills of the spatial-temporal zone adjacent to the study area.

The story of Balai Pustaka begins in 1908, a memorable year in the history of modern Indonesia, for that was the year in which Boedi Oetomo, the first nationalist organization in Indonesia, was founded. In the same year the Governor-General of the Dutch East Indies set up a Commissie voor de Volkslectuur, a Committee for Popular Literature. And even though there was no visible connexion between the founding of Boedi Oetomo and the setting up of this Committee, there certainly was an indirect link. Both the foundation of Boedi Oetomo and the need for an institution for popular literature had something to do with the expansion of modern education in the colony.

Abstract Han Jie (韩杰) belonged to the Flower Miao, a sub-group of the Miao in southwest China. When foreign missionaries began to evangelize among the Miao of China in the early twentieth century, they emphasized education and set up numerous schools to teach literacy. Learning literacy was not just an educational achievement, it allowed the Miao to imagine that they could have a better way out and be more than just poor farmers. Han Jie was the first generation of graduates of British Methodist Church schools, and he went on to set up more schools in remote areas, thus spreading literacy among poor Miao. Through contact and communication with different denominations, Han Jie felt that the Miao people needed an independent, self-reliant church；accordingly he poured his energy into increasing the sense of autonomy among the Flower Miao through evangelization and education. This paper examines the influence of Christian introduction to Miao identity and Miao ethnic relations through the biography of Han Jie. I argue that the history of religious proselytization transformed the Miao, their relations with their church ultimately determining their relations with the Chinese state as well. Thus Christian evangelization played a pivotal role in shaping Miao identity under the Nationalist regime of the Republic of China.

Jeanette Allen and Panos Vostanis describe the set-up and preliminary evaluation of a seven-week training programme for foster carers and supervising social workers based on attachment theory. It has long been recognised that parenting children with complex and challenging needs in a family setting is extremely demanding, with research indicating that foster carers' lack of confidence in managing such demands is a significant factor in placement breakdown. This study suggests that attachment theory provides a useful model to help carers understand and respond to the complex difficulties presented by children with a history of abuse and trauma, and that the provision of a conceptual framework may be a significant factor in improving foster carers' confidence to manage the difficulties presented by the children in their care. The clinical implications of this evaluation are discussed.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

This chapter traces the early history of state-sponsored informational filmmaking in Denmark, emphasising its organisation as a ‘cooperative’ of organisations and government agencies. After an account of the establishment and early development of the agency Dansk Kulturfilm in the 1930s, the chapter considers two of its earliest productions, both process films documenting the manufacture of bricks and meat products. The broader context of documentary in Denmark is fleshed out with an account of the production and reception of Poul Henningsen’s seminal film Danmark (1935), and the international context is accounted for with an overview of the development of state-supported filmmaking in the UK, Italy and Germany. Developments in the funding and output of Dansk Kulturfilm up to World War II are outlined, followed by an account of the impact of the German Occupation of Denmark on domestic informational film. The establishment of the Danish Government Film Committee or Ministeriernes Filmudvalg kick-started aprofessionalisation of state-sponsored filmmaking, and two wartime public information films are briefly analysed as examples of its early output. The chapter concludes with an account of the relations between the Danish Resistance and an emerging generation of documentarists.

Abstract In this paper, an evaluation was tried for the impact of structural design on structural response. Several situations are foreseen as the possibilities of changing the distribution of the structural elements (sails, columns, etc.), the width of the structure and the number of floors indicates the adapted type of bracing for a given structure by referring only to its Geometric dimensions. This was done by studying the effect of the technical design of the building on the natural frequency of the structure with the study of the influence of the distribution of the structural elements on the seismic response of the building, taking into account of the requirements of the Moroccan earthquake regulations 2000/2011 and using the ANSYS APDL and Robot Structural Analysis software.
