Mobile valuations : the Internet's impact on traditional valuation services

Preparing valuations is a time consuming process involving site inspections, research and report formulation. The ease of access to the internet has changed how and where valuations may be undertaken. No longer is it necessary to return to the office to finalise reports, or leave your desk in order to undertake research. This enables more streamlined service delivery and is viewed as a positive. However, it is not without negative impacts. This paper seeks to inform practitioners of the work environment changes flowing from increased access to the internet. It identifies how increased accessibility to, and use of, technology and the internet has, and will continue to, impact upon valuation service provision into the future.

Information Experience : Approaches to Theory and Practice

"The German word for experience - Erlebnis - the experience of the life, to live through something - underpins this book: making visible scholarly opportunities for richer and deeper contextualizations and examinations of the lived-world experiences of people in everyday contexts as they be, do and become." (Ross Todd, Preface). Information experience is a burgeoning area of research and still unfolding as an explicit research and practice theme. This book is therefore very timely as it distils the reflections of researchers and practitioners from various disciplines, with interests ranging across information, knowledge, user experience, design and education. They cast a fresh analytical eye on information experience, whilst approaching the idea from diverse perspectives. Information Experience brings together current thinking about the idea of information experience to help form discourse around it and establish a conceptual foundation for taking the idea forward. It therefore "provides a number of theoretical lenses for examining people's information worlds in more holistic and dynamic ways." (Todd, Preface)

Information Experience : Contemporary Perspectives

The purpose of this book is to open a conversation on the idea of information experience, which we understand to be a complex, multidimensional engagement with information. In developing the book we invited colleagues to propose a chapter on any aspect of information experience, for example conceptual, methodological or empirical. We invited them to express their interpretation of information experience, to contribute to the development of this concept. The book has thus become a vehicle for interested researchers and practitioners to explore their thinking around information experience, including relationships between information experience, learning experience, user experience and similar constructs. It represents a collective awareness of information experience in contemporary research and practice. Through this sharing of multiple perspectives, our insights into possible ways of interpreting information experience, and its relationship to other concepts in information research and practice, is enhanced. In this chapter, we introduce the idea of information experience. We also outline the book and its chapters, and bring together some emerging alternative views and approaches to this important idea.

Information experience : approaches to theory and practice

The Queensland University of Technology Research Team has recently edited a book on the idea of information experience. Authors from many parts of the world and focussed on many contexts have contributed chapters. The book represents the first attempt to profile and discuss information experience as a research domain and a research object, together with emphasis on different theories and methods being used in workplace, educational and community contexts. In this session members of the editorial team will introduce the book. We anticipate it will be of interest to any information professionals, students or researchers interested in understanding peoples' information experience.

Information literacy and the serious leisure participant : variation in the experience of using information to learn

This thesis examines, by way of phenomenographic methodology, the qualitatively different ways in which people engaged in Serious Leisure activities (within the area of 'heritage') experience information literacy. The study identified the presence of four distinct categories of information literacy experience, each with variation in regard to the serious leisure participant's experience of learning and information. In addition it also identified the existence of a further dimension of variation pertaining to the way in which individual identity is experienced during engagement with a serious leisure activity.

Citizens and social media in times of natural disaster: Exploring information experience

Introduction. Social media is becoming a vital source of information in disaster or emergency situations. While a growing number of studies have explored the use of social media in natural disasters by emergency staff, military personnel, medial and other professionals, very few studies have investigated the use of social media by members of the public. The purpose of this paper is to explore citizens’ information experiences in social media during times of natural disaster. Method. A qualitative research approach was applied. Data was collected via in-depth interviews. Twenty-five people who used social media during a natural disaster in Australia participated in the study. Analysis. Audio recordings of interviews and interview transcripts provided the empirical material for data analysis. Data was analysed using structural and focussed coding methods. Results. Eight key themes depicting various aspects of participants’ information experience during a natural disaster were uncovered by the study: connected; wellbeing; coping; help; brokerage; journalism; supplementary and characteristics. Conclusion. This study contributes insights into social media’s potential for developing community disaster resilience and promotes discussion about the value of civic participation in social media when such circumstances occur. These findings also contribute to our understanding of information experiences as a new informational research object.

Reliability and factorial validity of Adolescent Time Inventory-Time Attitude (ATI-TA) Scores in Scottish and Northern Irish adolescents

The contemporary literature investigating the construct broadly known as time perspective is replete with methodological and conceptual concerns. These concerns focus on the reliability and factorial validity of measurement tools, and the sample-specific modification of scales. These issues continue to hamper the development of this potentially useful psychological construct. An emerging body of evidence has supported the six-factor structure of scores on the Adolescent Time Inventory-Time Attitudes Scale, as well as their reliability. The present study utilized data from the first wave of a longitudinal study in the United Kingdom to examine the reliability, validity, and cross-cultural invariance of the scale. Results showed that the hypothesized six-factor model provided the best fit for the data; all alpha and omega estimates were >. .70; scores on ATI-TA factors related meaningfully to self-efficacy scores; and the factor structure was invariant across both research sites. Results are discussed in the context of the extant temporal literature.

Évaluation économique des services écosystémiques dans la région de Montréal : analyse spatiale et préférences exprimées

Les services écosystémiques (SE) réfèrent aux bénéfices que produisent et soutiennent la biodiversité et les écosystèmes et qui profitent à l’être humain. Dans beaucoup de cas, ils ne sont pas pris en compte dans le système économique. Cette externalisation des SE engendre des décisions sur l’utilisation du territoire et des ressources naturelles qui ignorent leur contribution à la qualité de vie des communautés. Afin notamment de sensibiliser l’opinion publique à l’importance des SE et de mieux les intégrer dans les processus décisionnels, ont été développées des démarches d’évaluation économique des SE. Dans cette thèse, nous avons cherché à comprendre à la fois comment l’utilisation passée et actuelle des sols dans la région de Montréal affecte la valeur des SE et comment ces aménités naturelles sont perçues et valorisées par la population, dans une perspective d’aménagement futur du territoire. Pour ce faire, nous avons utilisé deux approches : l’analyse spatiale recourant aux systèmes d’information géographique et l’analyse des préférences exprimées par des techniques d’enquête. Pour l’analyse spatiale, nous avons combiné des analyses cartographiques à des valeurs monétaires associées aux SE publiées dans la littérature. Nous avons alors estimé la valeur des écosystèmes d’un territoire par le transfert de bénéfices, de prix de marchés directs et de coûts évités. Cette démarche nous a permis de comprendre la relation entre l’utilisation actuelle du territoire du Grand Montréal écologique et la valeur des services fournis par les écosystèmes, que nous avons estimée à 2,2 milliards de dollars par année. Elle nous a permis aussi de mesurer les effets sur la valeur des SE du changement d’utilisation des sols entre les années 1960 et 2010. Nous avons montré que malgré différentes politiques de contrôle et d’encadrement de l’étalement urbain au cours de cette période, les pertes économiques non marchandes liées aux SE s’élèvent à 236 millions de dollars par année. Pour l’analyse des préférences exprimées, nous avons utlilisé deux méthodes, l’évaluation contingente et le choix multi-attributs, avec l’objectif de mesurer le consentement à payer de répondants pour des variations dans l’aménagement du territoire. Nous avons montré d’une part que les répondants valorisent significativement l’incidence des pratiques agro-environnementales sur la qualité de l’environnement et des paysages en consentant à payer entre 159 et 333 dollars par ménage par année pour une amélioration de la diversité du paysage agricole. D’autre part, leur volonté à payer pour l’amélioration de l’état des milieux humides du Québec est estimée entre 389 et 455 dollars par ménage par année. L’utilisation conjointe des deux méthodes nous a permis d’en comparer les résultats. Nous avons en outre démontré que le choix du format de question de valorisation de l’évaluation contingente affecte la convergence des résultats. Enfin, nous avons proposé des pistes de recherches futures portant sur l’intégration des démarches d’analyse biophysique, économique et politique dans des outils de prise de décision mieux adaptés à la dynamique des écosystèmes, de la biodiversité et des communautés humaines.

Research in Architecture: Looking Backward and Forward: Forty-Year Experience in Architectural Research at the Faculty of Architecture STU

The introduction of my contribution contains a brief information on the Faculty of Architecture of the Slovak University of Technology in Bratislava (FA STU) and the architectural research performed at this institution. Schemes and priorities of our research in architecture have changed several times since the very beginning in early 50’s. The most significant change occurred after “the velvet revolution” in 1989. Since 1990 there have been several sources to support research at universities. The significant part of my contribution is rooted in my own research experience since the time I had joined FA STU in 1975 as a young architect and researcher. The period of the 80’s is characterized by the first unintentional attempts to do “research by design” and my “scientific” achievements as by-products of my design work. Some of them resulted in the following issues: conception of mezzo-space, theory of the complex perception of architectural space and definition of basic principles of ecologically conscious architecture. Nowadays I continue my research by design within the application of so called solar envelope in urban scale with my students.

Research methodologies for planning ecotourism and nature conservation

Ecotourism is an important niche market in the world tourism industry. It is becoming increasingly popular as an alternative to mass tourism. The emergence of ecotourism was facilitated by the environmental damage associated with mass tourism. Ecotourism is defined in many ways and there is no consensus as to its exact meaning. However, a number of salient elements, such as environmental conservation, maintenance of biodiversity, a satisfying experience for the visitors, study and appreciation of nature and sustainable community development, are included in many definitions. Tourism creates negative environmental externalities in the form of environmental damage. Such adverse effects can have serious implications for the tourism industry because they damage the very natural resource that forms the raw material for ecotourism. Ecotourism ventures should thus be properly planned and implemented and carefully monitored. Proper planning of ecotourism is hampered by the paucity of relevant qualitative and quantitative information. The use of analytical tools such as the Contingent Valuation Method, carrying capacity, decision analysis techniques with which multiobjective and uncertain consequences can be analysed, and other management strategies, such as the Safe Minimum Standard, can be useful in enabling better planning of ecotourism. Ecotourism can thus enhance the opportunities for better management of natural resources while providing a satisfying experience for the visitor.

The role of uncertainty in the relationship between fairness evaluations and willingness to pay

Participants in contingent valuation studies may be uncertain about a number of aspects of the policy and survey context. The uncertainty management model of fairness judgments states that individuals will evaluate a policy in terms of its fairness when they do not know whether they can trust the relevant managing authority or experience uncertainty due to insufficient knowledge of the general issues surrounding the environmental policy. Similarly, some researchers have suggested that, not knowing how to answer WTP questions, participants convey their general attitudes toward the public good rather than report well-defined economic preferences. These contentions were investigated in a sample of 840 residents in four urban catchments across Australia who were interviewed about their WTP for stormwater pollution abatement. Four sources of uncertainty were measured: amount of prior issue-related thought, trustworthiness of the water authority, insufficient scenario information, and WTP response uncertainty. A logistic regression model was estimated in each subsample to test the main effects of the uncertainty sources on WTP as well as their interaction with fairness and proenvironmental attitudes. Results indicated support for the uncertainty management model in only one of the four samples. Similarly, proenvironmental attitudes interacted rarely with uncertainty to a significant level, and in ways that were more complex than hypothesised. It was concluded that uncertain individuals were generally not more likely than other participants to draw on either fairness evaluations or proenvironmental attitudes when making decisions about paying for stormwater pollution abatement.

Essays in environmental economic valuation and decision making in the presence of an environmental disaster

The first essay developed a respondent model of Bayesian updating for a double-bound dichotomous choice (DB-DC) contingent valuation methodology. I demonstrated by way of data simulations that current DB-DC identifications of true willingness-to-pay (WTP) may often fail given this respondent Bayesian updating context. Further simulations demonstrated that a simple extension of current DB-DC identifications derived explicitly from the Bayesian updating behavioral model can correct for much of the WTP bias. Additional results provided caution to viewing respondents as acting strategically toward the second bid. Finally, an empirical application confirmed the simulation outcomes. The second essay applied a hedonic property value model to a unique water quality (WQ) dataset for a year-round, urban, and coastal housing market in South Florida, and found evidence that various WQ measures affect waterfront housing prices in this setting. However, the results indicated that this relationship is not consistent across any of the six particular WQ variables used, and is furthermore dependent upon the specific descriptive statistic employed to represent the WQ measure in the empirical analysis. These results continue to underscore the need to better understand both the WQ measure and its statistical form homebuyers use in making their purchase decision. The third essay addressed a limitation to existing hurricane evacuation modeling aspects by developing a dynamic model of hurricane evacuation behavior. A household's evacuation decision was framed as an optimal stopping problem where every potential evacuation time period prior to the actual hurricane landfall, the household's optimal choice is to either evacuate, or to wait one more time period for a revised hurricane forecast. A hypothetical two-period model of evacuation and a realistic multi-period model of evacuation that incorporates actual forecast and evacuation cost data for my designated Gulf of Mexico region were developed for the dynamic analysis. Results from the multi-period model were calibrated with existing evacuation timing data from a number of hurricanes. Given the calibrated dynamic framework, a number of policy questions that plausibly affect the timing of household evacuations were analyzed, and a deeper understanding of existing empirical outcomes in regard to the timing of the evacuation decision was achieved.

Reliability analysis of encapsulation methods for lead -based paint through an accelerated life testing

The adverse health effects of long-term exposure to lead are well established, with major uptake into the human body occurring mainly through oral ingestion by young children. Lead-based paint was frequently used in homes built before 1978, particularly in inner-city areas. Minority populations experience the effects of lead poisoning disproportionately. ^ Lead-based paint abatement is costly. In the United States, residents of about 400,000 homes, occupied by 900,000 young children, lack the means to correct lead-based paint hazards. The magnitude of this problem demands research on affordable methods of hazard control. One method is encapsulation, defined as any covering or coating that acts as a permanent barrier between the lead-based paint surface and the environment. ^ Two encapsulants were tested for reliability and effective life span through an accelerated lifetime experiment that applied stresses exceeding those encountered under normal use conditions. The resulting time-to-failure data were used to extrapolate the failure time under conditions of normal use. Statistical analysis and models of the test data allow forecasting of long-term reliability relative to the 20-year encapsulation requirement. Typical housing material specimens simulating walls and doors coated with lead-based paint were overstressed before encapsulation. A second, un-aged set was also tested. Specimens were monitored after the stress test with a surface chemical testing pad to identify the presence of lead breaking through the encapsulant. ^ Graphical analysis proposed by Shapiro and Meeker and the general log-linear model developed by Cox were used to obtain results. Findings for the 80% reliability time to failure varied, with close to 21 years of life under normal use conditions for encapsulant A. The application of product A on the aged gypsum and aged wood substrates yielded slightly lower times. Encapsulant B had an 80% reliable life of 19.78 years. ^ This study reveals that encapsulation technologies can offer safe and effective control of lead-based paint hazards and may be less expensive than other options. The U.S. Department of Health and Human Services and the CDC are committed to eliminating childhood lead poisoning by 2010. This ambitious target is feasible, provided there is an efficient application of innovative technology, a goal to which this study aims to contribute. ^
