The Potential of X‐Ray Diffraction in the Analysis of Burned Remains from Forensic Contexts*
Full text linkIn view of the difficulties in extracting quantitative information from burned bone, we suggest a new and accurate method of determining the temperature and duration of burning of human remains in forensic contexts. Application of the powder X-ray Diffraction approach to a sample of human bone and teeth allowed their microstructual behaviour, as a function of temperature (200-1000°C) and duration of burning (0, 18, 36 and 60 min), to be predicted. The experimental results from the bones and teeth determined that the growth of hydroxylapatite crystallites is a direct and predictable function of the applied temperature, which follows a non-linear logistic relationship. This will allow the forensic investigator to acquire useful information about the equilibrium temperature brought about by the burning process and to suggest a reasonable duration of fire exposure
Player agency in interactive narrative: audience, actor & author
Full text linkThe question motivating this review paper is, how can
computer-based interactive narrative be used as a constructivist learn-
ing activity? The paper proposes that player agency can be used to
link interactive narrative to learner agency in constructivist theory,
and to classify approaches to interactive narrative. The traditional
question driving research in interactive narrative is, ‘how can an in-
teractive narrative deal with a high degree of player agency, while
maintaining a coherent and well-formed narrative?’ This question
derives from an Aristotelian approach to interactive narrative that,
as the question shows, is inherently antagonistic to player agency.
Within this approach, player agency must be restricted and manip-
ulated to maintain the narrative. Two alternative approaches based
on Brecht’s Epic Theatre and Boal’s Theatre of the Oppressed are
reviewed. If a Boalian approach to interactive narrative is taken the
conflict between narrative and player agency dissolves. The question
that emerges from this approach is quite different from the traditional
question above, and presents a more useful approach to applying in-
teractive narrative as a constructivist learning activity

No full textHeat-induced dimensional changes in bone and their consequences for forensic anthropology
No full textAn understanding of heat-induced transformation of hard tissue is vital before a full interpretation of burned human remains can be successfully achieved. Samples of modern sheep (n = 60) were analyzed resulting in 5440 data points. An experimental approach was undertaken that explored the bi-variable impact of heating temperature and duration of burning. Subsequent heat-induced bone changes included the progression of color from natural through to blue-white, the significant loss of weight, the reduction in mechanical strength, the development of distinct fracture patterns, alterations in the microscopic porosity, substantial alterations in crystalline structure and reduction and expansion in size. Collation and integration of this information demanded a revision of the four stages of heat-induced degradation of bone previously presented by Mayne Correia (1) and Thompson (2). The results demonstrate that heat-induced shrinkage is also accompanied by expansion and that both can be statistically significant. This suggests that anthropological techniques applied to burned bone will likely be detrimentally affected and accuracy will be reduced
The abrasion of modern and archaeological bones by mobile sediments: the importance of transport modes.
No full textFresh, weathered, archaeological and fossilized bones were subjected to a series of abrasion experiments using fine sand in an annular flume in order to link bone-surface abrasion to flow regimes and sediment transport modes, compare these effects on bones of different states, and quantify the extent and types of wear occurring. Flow velocities were chosen to replicate the predominant transport modes of bedload, saltation and suspension.Comparative scanning electron microscopic image analysis was performed to assess the degree and type of wear occurring on each bone type for the different transport modes over a range of exposure periods from 24 to 72 h.These preliminary investigations have shown that both the amount and type of wear experienced was related to the bone type, duration of exposure and the mode of sediment transport with wear being the result of deformation, rather than cutting wear.The formation of scour pits in the sand bed on the upstream side of the bone samples significantly reduced wear, and appears to be an important control mechanism for impact related wear that has been overlooked until now
Supply and demand: The shifting expectations of forensic anthropology in the United Kingdom
No full textForensic anthropology is a relatively young discipline in the United Kingdom. Practitioners utilise techniques devised and adapted within the field of biological anthropology and attempt to contribute towards the identification of deceased individuals within the forensic context. Traditionally this means the examination of the human skeleton in an attempt to either create biological boundaries of the deceased thus reducing the number of potential identifications, or to compare the remains with ante-mortem records to positively identify the deceased. Usually an osteological profile is generated containing estimates of biological sex, age at death and stature and information on pathologies and traumas. Current diversification and pioneering research within the field of forensic anthropology now means that forensic anthropologists can contribute towards the idenification of living individuals with the use of such methods as facial rcognition, ear mark identification and DNA analysis. In the UK its origins lie mainly in the field of archaeology
Temporality in L2 Spanish: an investigation of the expression of temporality in the narrative discourse of Spanish L2 learners
Full text linkThe general objective o f this research study is the investigation of the development of the expression of temporality in Second Language Acquisition. In particular, this study examines the acquisition process by native English speakers who are second languages learners of Spanish Temporality is examined as it is manifested in the oral narration of events by these learners. The theoretical argument behind the research is based on linguistic relativity and “thinking for speaking” theories which consider how different languages deal with the linguistic coding of certain concepts, such as time and space, and the influence of linguistic forms on speakers’ perceptions and cognitive development of these concepts. The present study aims to answer the following question.
If the language they speak influences the manner in which speakers conceptualise temporal relations, will learners of a second language adopt the cognitive strategies and styles of the native speakers to refer to events in time, as their Interlanguage develops to approximate the target language? Specifically, will second language learners of Spanish adopt the patterns of temporal expression m narrative discourse, typical of Spanish native speakers? To answer this question standard qualitative and quantitative methods of research used in applied linguistics are utilized
