Soil erosion is a major problem around the world because of its effects on soil productivity, nutrient loss, siltation in water bodies, and degradation of water quality. By understanding the driving forces behind soil erosion, we can more easily identify erosion-prone areas within a landscape to address the problem strategically. Soil erosion models have been used to assist in this task. One of the most commonly used soil erosion models is the Universal Soil Loss Equation (USLE) and its family of models: the Revised Universal Soil Loss Equation (RUSLE), the Revised Universal Soil Loss Equation version 2 (RUSLE2), and the Modified Universal Soil Loss Equation (MUSLE). This paper reviews the different sub-factors of USLE and RUSLE, and analyses how different studies around the world have adapted the equations to local conditions. We compiled these studies and equations to serve as a reference for other researchers working with (R)USLE and related approaches. Within each sub-factor section, the strengths and limitations of the different equations are discussed, and guidance is given as to which equations may be most appropriate for particular climate types, spatial resolution, and temporal scale. We investigate some of the limitations of existing (R)USLE formulations, such as uncertainty issues given the simple empirical nature of the model and many of its sub-components; uncertainty issues around data availability; and its inability to account for soil loss from gully erosion, mass wasting events, or predicting potential sediment yields to streams. Recommendations on how to overcome some of the uncertainties associated with the model are given. Several key future directions to refine it are outlined: e.g. incorporating soil loss from other types of soil erosion, estimating soil loss at sub-annual temporal scales, and compiling consistent units for the future literature to reduce confusion and errors caused by mismatching units. The potential of combining (R)USLE with the Compound Topographic Index (CTI) and sediment delivery ratio (SDR) to account for gully erosion and sediment yield to streams respectively is discussed. Overall, the aim of this paper is to review the (R)USLE and its sub-factors, and to elucidate the caveats, limitations, and recommendations for future applications of these soil erosion models. We hope these recommendations will help researchers more robustly apply (R)USLE in a range of geoclimatic regions with varying data availability, and modelling different land cover scenarios at finer spatial and temporal scales (e.g. at the field scale with different cropping options).

The purpose of this research was to examine the effects of Inquiry-Based Learning (IBL) on the academic achievement, attitudes, and engagement of fifth-grade science students. Participants were from two science classes (N = 42). The experimental group received IBL instruction, while the control group received traditional instruction. Pretests and posttests were used to measure students' academic achievement during the 6-week study. The Science Attitudes Survey was administered to students pre-intervention and post-intervention to assess overall student attitudes about science. Student engagement was measured 3 days a week with a student engagement checklist. Fieldnotes recorded by the teacher-researcher were used for additional documentation. Students in the IBL group scored higher than students in the traditional group on the academic achievement posttest, although not statistically significant. Students who received IBL instruction showed a slight statistically insignificant decrease in their positive attitudes towards science but higher engagement as compared to students who received traditional instruction.

Due to its location within the typhoon belt, the Philippines is vulnerable to tropical cyclones that can cause destructive floods. Climate change is likely to exacerbate these risks through increases in tropical cyclone frequency and intensity. To protect populations and infrastructure, disaster risk management in the Philippines focuses on real-time flood forecasting and structural measures such as dikes and retaining walls. Real-time flood forecasting in the Philippines mostly utilises two models from the Hydrologic Engineering Center (HEC): the Hydrologic Modeling System (HMS) for watershed modelling, and the River Analysis System (RAS) for inundation modelling. This research focuses on using non-structural measures for flood mitigation, such as changing land use management or watershed rehabilitation. This is being done by parameterising and applying the Land Utilisation and Capability Indicator (LUCI) model to the Cagayan de Oro watershed (1400 km2) in southern Philippines. The LUCI model is capable of identifying areas providing ecosystem services such as flood mitigation and agricultural productivity, and analysing trade-offs between services. It can also assess whether management interventions could enhance or degrade ecosystem services at fine spatial scales. The LUCI model was used to identify areas within the watershed that are providing flood mitigating services and areas that would benefit from management interventions. For the preliminary comparison, LUCI and HEC-HMS were run under the same scenario: baseline land use and the extreme rainfall event of Typhoon Bopha. The hydrographs from both models were then input to HEC-RAS to produce inundation maps. The novelty of this research is two-fold: (1) this type of ecosystem service modelling has not been carried out in the Cagayan de Oro watershed; and (2) this is the first application of the LUCI model in the Philippines. Since this research is still ongoing, the results presented in this paper are preliminary. As the land use and soil parameterisation for this watershed are refined and more scenarios are run through the model, more robust comparisons can be made between the hydrographs produced by LUCI and HEC-HMS and how those differences affect the inundation map produced by HEC-RAS.

Northumberland has a long history of public engagement surrounding its ancient rock-art. Recent advances in digital technologies have enabled archaeologists to enrich this engagement through the provision of open access to substantial rock-art datasets online. Building on these achievements, the Rock Art on Mobile Phones (RAMP) project allows Northumberland's countryside visitors to access in situ interpretation at three rock-art areas on their mobile phones. During the RAMP co-experience workshops it emerged that the key issues the public expected to be addressed by the mobile interpretation included locating rock-art, the desire for ambiguity and speculation about rock-art, and connecting to the landscape. The paper discusses, on the one hand, how these themes were incorporated into RAMP's conceptual design and, on the other hand, how RAMP themes compare with the Audience Development Plan produced by the archaeologists who created an online database. We consider the implications of these findings for the development of open-access online resources and in situ public interpretation.

The Contemporary Relevance of Kant’s Transcendental Psychology
2018
The purpose of this thesis is to demonstrate the contemporary relevance of Kant’s transcendental psychology against the orthodoxy of the dominant analytic school of philosophy, in an aim to salvage it from criticisms that resulted in the widespread view that Kant had little to say about the mind that was correct or useful. Historically, this had led to the near exclusion of Kant’s views of the mind from mainstream philosophical debate; those who acknowledged intellectually the psychological import of the work deemed as having transgressed the bounds of proper philosophy. It is argued that this was, and still is, an unfortunate and narrow view, since an interpretation which fully embraces the transcendental aspect can provide invaluable insights and direction for contemporary research in cognitive science and cognitive neuroscience. A major focus of this work is to provide a rigorous conceptual analysis of the modern problem of consciousness and to show that every approach has become a response, positive or negative, to the Cartesian distinction between body and mind. Today, more than three hundred years after Descartes’ philosophical dualism, this powerful and persuasive argument still continues to hold fast. Cognitive neuroscientists have amassed a deep and detailed understanding of how our brains process information from the external world, but the question of how this information is transformed into conscious experience is deemed an unsolved problem. It is proposed that, although Kant never uses the concept of consciousness in the now dominant sense of phenomenal qualia, his theory of the transcendental subject is a valuable tool in unravelling the philosophical complexities that are commonplace in current theories.

The Deaf Acculturation Scale (DAS): Development and Validation of a 58-Item Measure
2011
This study involved the development and validation of the Deaf Acculturation Scale (DAS), a new measure of cultural identity for Deaf and hard-of-hearing (hh) populations. Data for this study were collected online and involved a nationwide sample of 3,070 deaf/hh individuals. Results indicated strong internal reliabilities for all the subscales, and construct validity was established by demonstrating that the DAS could discriminate groups based on parental hearing status, school background, and use of self-labels. Construct validity was further demonstrated through factorial analyses, and findings resulted in a final 58-item measure. Directions for future research are discussed.

Traditional storytelling in a digital world: the transformative power of storytelling across media

Storytelling
2010
I see stories. At the bus stop, in the pub, even on Twitter. It's how we communicate. This thesis is no different. It tells lots of stories, how you hear them depends on the reader as much as the writer. One of the stories in this book is of my own personal journey from a lowly PhD student to a fully fledged member of the storytelling community in Scotland. The personal narrative is woven throughout the text as a series of reflections and diary extracts. Another story is the development of Blether Tay-gither, the local Dundee-based storytelling group which was set up during the course of my research and continues to grow in leaps and bounds. Blether Tay-gither gave me my ticket into the storytelling world, validating my credentials.The main tale however, is that of storytelling in contemporary, technological society. What does it mean to be a storyteller? Why would someonebecome a storyteller? And what possible relevance could it have to today's society? These questions are answered largely by the tellers themselvesthrough a series of interview snapshots and discussions. What is not addressed by them, though, is the relationship between storytelling and digital technology, or new media. Whilst storytellers are not inherently anti-technology, they are not in general, avid consumers of digital media. Yet by comparing a set of characteristics for storytelling and new media (generated through extensive participant observation), and developing a lens for reflection, the connections between them can be probed. These connections are proof in and of themselves of the continued relevance and need for engaging stories and strongly suggest that creative technology-enabled storytelling experiences would be well received. A set of such creative hybridised storytelling environments was developed by introducing young designers to traditional stories and storytelling techniques, allowing them to generate a range of innovative prototypes. This case study is examined in some detail and the reflection tool used to consider the success of each conceptual idea.
