Opencast extraction records and field data have shown the existence of distinct levels of thrust development as isolated structures and basal detachments within imbricate systems. Two areas have been studied where the thrust faults exhibit similar features which have formed by different propagation mechanisms. At Nant Helen opencast site major thrusts are separated by smaller isolated structures, which apparently do not link to a basal decollement below the site. The isolated thrusts are adduced to have formed due to fluid over-pressuring and mechanical anisotropies in the rock sequence. In the Ffyndaff district deformation at the Ffyndaff opencast site is characterised by a series of foreland propagating thrusts linked by a detachment below the Nine Foot Seam, whereas to the west at Rhigos and Dunraven the detachment rises to a higher level and is interpreted as a...

The principal structurally controlled iscontinuities are those associated with tilting, folding and faulting. The former result from bedding plane slip during flexural folding that smoothes the bedding planes and reduces cohesion. The latter are produced by fault movements that weaken the rock and produce a structural nisotropy in the fault surface. Both are likely to confine the movement ofwater through the rock, enhancing weathering and further weakening the surface. In open pit design, the stability of the highwall is discussed in relation to the orientation of the various types of structurally controlled discontinuity. A case study from Ffyndaff Opencast Coal Site in the South Wales Coalfield is an...

The data were collected from 900 students: 300 in lower secondary school, 300 in upper secondary school and 300 in vocational education and training using a face-to-face administered survey questionnaire. Exploratory factor analysis was conducted to determine the nature of the constructs or dimensions quantifying the image of vocational education and students’ loyalty towards VET. Correlation analysis was used to examine the relationships between the independent variables that comprised the image of VET and the dependant variables of students’ loyalty and, finally, regression analysis was used to measure the impact of the image of VET on the students’ loyalty. Three main findings emerged from the study: (1) ...

Two reviewers were appointed on the basis of their independence and they reviewed the full paper devoid of the authors’ names and institutions in order to ensure objectivity and anonymity. Papers were reviewed according to specified criteria, including relevance to the conference theme and sub-themes, originality, quality and presentation. Following review and acceptance, this full paper was presented at the international conference.

To date, insufficient research has been conducted concerning children who experience deployment (Siebler, 2015). This study seeks to provide valuable insights into young children's understandings and experiences of their parents' military deployment in an Australian context. An adapted research framework, based on the policies from the United Nations Convention on the Rights of the Child (UNICEF, 2015) and Clark and Moss (2011), has been created to listen to and privilege the often marginalised child's voice. Employing a qualitative research approach known as Mosaic research, multiple methods of data collection are combined to gather various insights into children's experiences. Embracing an interpretivist epistemology, the researcher aims to create shared knowledges of children's understandings and...
