A Physical and Social Study of Mountain Bike Use on Five Segments of the Continental Divide National Scenic Trail in Colorado

This capstone reviews uses of the Continental Divide National Scenic Trail. Policies governing use of the trail appear to be ambiguous, especially regarding mountain bicycles. Mountain biking has grown since the trail was created, but is not fully addressed in existing or proposed policy. 382 people on five segments of the trail in Colorado were interviewed for this capstone. Mountain bikes, hiking, and motorized recreation were observed uses. User conflict, overcrowding, degraded recreation experiences, or user displacement was not reported. User satisfaction was high and most would return. Interviewees requested increased public involvement and recognition of user needs in setting policy. Trail degradation occurs, but is unassociated with any particular use. Recommendations for trail improvement and maintenance are presented.

Geodaesia, or, The art of surveying and measuring land made easy : shewing by plain and practical rules, to survey, protract, cast up, reduce or divide any piece of land whatsoever : with new tables for the ease of the surveyor in reducing the measure of land : moreover a more facile and sure way of surveying by the chain, than has hitherto been taught. As also to lay out new lands in America, or elsewhere: and how to make a perfect map of a river's mouth or harbour; with several other things never before published in our language.

Modelling cell lifespan and proliferation: is likelihood to die or to divide independent of age?

In cell lifespan studies the exponential nature of cell survival curves is often interpreted as showing the rate of death is independent of the age of the cells within the population. Here we present an alternative model where cells that die are replaced and the age and lifespan of the population pool is monitored until a, steady state is reached. In our model newly generated individual cells are given a determined lifespan drawn from a number of known distributions including the lognormal, which is frequently found in nature. For lognormal lifespans the analytic steady-state survival curve obtained can be well-fit by a single or double exponential, depending on the mean and standard deviation. Thus, experimental evidence for exponential lifespans of one and/or two populations cannot be taken as definitive evidence for time and age independence of cell survival. A related model for a dividing population in steady state is also developed. We propose that the common adoption of age-independent, constant rates of change in biological modelling may be responsible for significant errors, both of interpretation and of mathematical deduction. We suggest that additional mathematical and experimental methods must be used to resolve the relationship between time and behavioural changes by cells that are predominantly unsynchronized.

Bridging the divide between theory and practice. Experiential learning approaches for tourism and hospitality education

Experiential learning approaches such as role-play have been found to be valuable methods of bridging the divide between academic knowledge and practical skills, a problem often cited in tourism and hospitality management education. Such approaches have been found to contribute towards deeper learning by enhancing students' interest, motivation, participation, knowledge and skill development. This paper reports on the implementation of an experiential learning approach designed to encourage and facilitate deeper learning approaches, with the contributing aims of providing students with a more interesting learning experience and a broader set of skills for future employment.

The theory-practice divide:thoughts from the Editors and Senior Advisory Board of EJM

Purpose – The purpose of this editorial is to bring together thoughts and opinions from the Editors and Senior Advisory Board of EJM regarding the nature of the long-debated “theory-practice divide” in marketing scholarship. Design/methodology/approach – The authors synthesise diverse opinions from senior academics in order both to inspire further debate in marketing scholarship, and to draw some important conclusions for marketing academia as a whole. Findings – The authors propose that, for marketing scholarship to mature and progress, room must be found for those who wish to focus both on practical and on pure marketing scholarship. Career advancement from both routes is vital. Research limitations/implications – The topic of the theory-practice gap is complex. Many diverse opinions are cited and, due to space constraints, the coverage of many issues is necessarily brief. Practical implications – Scholars should find the thoughts contained in the paper of significant interest. Originality/value – The paper appears to be the first to bring together such a set of diverse opinions on the subject, and to try to draw some overall pragmatic conclusions, while still recognising the multiplicity of valid thought in the area.

Examining the process of regime change in the North Atlantic Treaty Organization: The divide between rhetoric and reality

The North Atlantic Treaty Organization (NATO) is a product of the Cold War through which its members organized their military forces for the purpose of collective defense against the common threat of Soviet-backed aggression. Employing the terminology of regime theory, the creation of NATO can be viewed as the introduction of an international security regime. Throughout the Cold War, NATO member states preserved their commitment to mutual defense while increasingly engaging in activities aimed at overcoming the division of Europe and promoting regional stability. The end of the Cold War has served as the catalyst for a new period of regime change as the Alliance introduced elements of a collective security regime by expanding its mandate to address new security challenges and reorganizing both its political and military organizational structures. ^ This research involves an interpretive analysis of NATO's evolution applying ideal theoretical constructs associated with distinct approaches to regime analysis. The process of regime change is investigated over several periods throughout the history of the Alliance in an effort to understand the Alliance's changing commitment to collective security. This research involves a review of regime theory literature, consisting of an examination of primary source documentation, including official documents and treaties, as well as a review of numerous secondary sources. This review is organized around a typology of power-based, organization-based, and norm-based approaches to regime analysis. This dissertation argues that the process of regime change within NATO is best understood by examining factors associated with multiple theoretical constructs. Relevant factors provide insights into the practice of collective security among NATO member states within Europe, while accounting for the inability of the NATO allies to build on the experience gained within Europe to play a more central role in operations outside of this region. This research contributes to a greater understanding of the nature of international regimes and the process of regime change, while offering recommendations aimed at increasing NATO's viability as a source of greater security and more meaningful international cooperation.^
