An Introduction to Visual Research Methods in Tourism
No full textAn Introduction to Visual Research Methods in Tourism, is the first book to present, discuss and promote the use of a range of visual methods, including still images (such as photographs, postcards, drawings) and moving images (such as video) within the context of tourism research. The book focuses on key issues important for students, researchers and academics actively doing visual tourism research or those who are contemplating using these methods. These range from the questions surrounding philosophical approaches, (inter)disciplinary location, range and choice of methods, implementation and data analysis techniques to provide an essential guide to using visual methods in tourism research. While recognising that visual methods are predominantly employed within qualitative research, this text will discuss various philosophical approaches and academic disciplines indicating how these influence a particular choice of visual method, mode of implementation and type of analysis. In this regard this book will incorporate perspectives from a range of disciplines including anthropology, geography and sociology, demonstrating how these might be applied within the context of studies in tourism. The discussions surrounding these key issues are supplemented with international case studies from existing research to show how these methods are used in practice. In addition to this practical tip boxes are included to help avoid some of the pitfalls associated with visual research

Innovative techniques in tourism research: an exploration of visual methods and academic filmmaking
No full textWhile visual methods have long been utilised as legitimate research techniques in the social sciences, within mainstream tourism research these techniques are rarely employed. This paper thus seeks to question current research practices in tourism by focusing on academic filmmaking as an innovative visual method which can be used to approach tourism research in a new way and to create tourism knowledge which is widely accessible. Two case studies explicate these points: an ethnographic documentary about tourism impacts in Crete, and a doctoral project which explored the construction and consumption of images of Greekness by visitors to the Athenian Acropoli
Axon overproduction and elimination in the corpus callosum of the developing rhesus monkey
No full textWe have studied the cytological and quantitative aspects of axon addition and elimination in the corpus callosum of the developing rhesus monkey. Electron microscopic analysis reveals that during fetal development the number of callosal axons increases from 4 million at embryonic day 65 (E65) to 188 million at birth (E 165). Thus, the number of callosal axons in newborn monkeys exceeds the number present in the adult (an average of 56 million; LaMantia and Rakic, 1990a) by at least 3.5 times. Although there is some variability among the 11 fetal and newborn monkeys examined, there appears to be a progressive increase in the total number of callosal axons from midgestation through birth. The presence and numbers of growth cones from E65 through birth suggests that axon addition occurs exclusively during this period. There is no ultrastructural or quantitative indication of postnatal axon addition. After birth, about 70% of the axons in the callosum are eliminated in 2 phases. During the first phase, which includes the first 3 postnatal weeks, approximately 80 million axons are lost at an estimated rate of 4.4 million/d or 50/sec. During the second phase, which continues for the following 3 months, an additional 50 million axons are eliminated at a rate of 0.5 million/d or 5/sec until the adult value is reached. A discontinuous distribution of different classes of axons along the anterior-posterior axis of the tract reminiscent of the pattern seen in the adult is detectable before the onset of the first phase of axon elimination. Since the basic topography and terminal field patterns of callosal projections are well established before birth in all regions of the monkey cortex examined so far (Goldman-Rakic et al., 1983; Killackey and Chalupa, 1986; Dehay et al., 1988; Schwartz and Goldman-Rakic, 1990), we conclude that the massive postnatal elimination of callosal axons described here is unlikely to play a significant role in the development of discretely patterned callosal projection zones or their columnar terminations. The coincidence of axon elimination and the increase in synaptic density throughout the primate cerebral cortex during the first 6 postnatal months (Rakic et al., 1986), however, suggests that supernumerary axons may be lost during a process that results in the local proliferation of synapses from a subset of initial interhemispheric projections.</jats:p
The Effect of Multiple Transverse Modes in Self-Mixing Sensors Based on Vertical-Cavity Surface-Emitting Lasers
No full textIn this work we investigate the effect of multiple transverse modes, such as those found in Vertical-Cavity Surface-Emitting Lasers, in self-mixing sensors. We show that the sensitivity of the system and the accuracy of the measurement changes periodically with target distance
