The Quays In Salford: An Analysis Of Visitor Perceptions, Satisfaction And Behavioural Intention, Ruth Craggs, Peter Schofield

Articles

Despite an extensive literature on urban regeneration, visitor perceptions of urban waterfront destinations and their subsequent outcomes remain largely
unexplored. The paper reports the findings from a survey of visitors to the Quays in Salford; it focuses on their perceptions, satisfaction and behavioural intentions. While the primary attractions were found to have an important influence, the secondary elements explain more of the variance in
overall satisfaction and intention to return to the Quays and the environmental aspects have a greater influence on visitor intention to recommend the destination. The implications of the findings for destination management and marketing are discussed.

From Climate Change And Hurricanes To Ecological Nuisances: Common Law Remedies For Public Law Failures?, Stephen M. Johnson

Articles

Part I of this article explores the role that the common law played in addressing environmental problems prior to the development of a robust public law regime in the 1970s and the changing role of common law as the new regime was implemented. Part II of the article examines the reasons why there has been a renaissance in common law actions and why the trend could continue. Part III of the article discusses the recent federal appellate court decisions that could accelerate the common law renaissance, as well as some other recent federal court decisions that could slow the renaissance. …

Use Of A Bent Single Sms Fiber Structure For Simultaneous Measurement Of Displacement And Temperature Sensing, Qiang Wu, Agus Hatta, Pengfei Wang, Yuliya Semenova, Gerald Farrell

Articles

We have proposed the use of a single bent single-multiple-single mode (SMS) fiber structure to measure both displacement and temperature simultaneously and independently. Our experimental results show that this sensor has a sensitivity of 5.89 pm/μm for displacement and 11.6 pm/ºC for temperature.

Optimum Design For Maximun Wavelength Resolution For An Edge Filter Based Ratiometric System, Qiang Wu, Ginu Rajan, Pengfei Wang, Yuliya Semenova, Gerald Farrell

Articles

In this letter, we propose a high resolution temperature insensitive interrogation technique for FBG sensors where one FBG acts as an edge filter to interrogate a separate FBG sensor. A high resolution of better than 5 με in strain measurement range from 0 to 1100 με and the best resolution of better than 1 με were verified by experiments. An error of only ±2.2 με is achieved over a temperature range from 15 to 50 °C, indicating that this strain interrogation technique is temperature insensitive. Using an altered system configuration, the temperature was also measured simultaneously with a resolution better …

A Hybrid Fiber Optic Sensing System For Simultaneous Strain And Temperature Measurement And Its Application, Ginu Rajan, Karolina Milenko, Piotr Lesiak, Yuliya Semenova, Anna Boczkowska, Manjusha Ramakrishnan, Kazimierz Jedrzejewski, Andrzej Domanski, Tomasz Wolinski, Gerald Farrell

Articles

A hybrid fiber optic sensor by integrating polarimetric fiber sensors and fiber Bragg grating sensors for simultaneous strain and temperature measurement is presented in this paper. Two types of polarimetric fiber sensors are used; a Panda fiber and a polarization maintaining photonic crystal fiber. The polarimetric strain sensors give the average strain and temperature information, while the fiber Bragg grating sensors give localized strain information. Two applications of the proposed configuration are also demonstrated in this paper. In the composite materials three fiber sensors are used while for other engineering applications a temperature insensitive polarimetric fiber sensor can be used …

Simple Design Technique For A Triangular Fbg Filter Based On A Linearly Chirped Grating, Qiang Wu, Gerald Farrell, Yuliya Semenova

Articles

A novel and simple design technique for triangular spectrum response of fibre Bragg grating (FBG) is pre- 21 sented based on a linear chirped grating. It is shown that this method is fast and can give a straightfor- 22 ward solution to meet a design target. The numerical simulation examples verified the effectiveness of 23 the design method. A general approach to design for multichannel triangular spectral responses for 24 FBG filters is proposed, which provides a solution that achieves a minimum change of refractive index 25 for the fibre.

Humidity Sensor Based On A Photonic Crystal Fiber Interferometer, Jinesh Mathew, Yuliya Semenova, Ginu Rajan, Gerald Farrell

Articles

A photonic crystal fiber interferometer that operates in reflection mode for humidity detection is presented for the first time which has the advantage that it does not require the use of any hygroscopic material. The fabrication of the sensor head is therefore simple since it only involves cleaving and splicing. The all-silica nature of the device has the potential for many applications.

Experimental Demonstration Of A Simple Displacement Sensor Based On A Bent Singlemode-Multimode-Singlemode (Sms) Fiber Structure, Qiang Wu, Yuliya Semenova, Pengfei Wang, Agus Hatta, Gerald Farrell

Articles

A simple displacement sensor based on a bent singlemode-multimode-singlemode (SMS) fiber structure is proposed and experimentally investigated. The sensor offers a wider displacement range, not limited by the risk of fiber breakage, as well as a three-fold increase in displacement sensitivity by comparison with a straight SMS structure sensor. This sensor can be interrogated by either an optical spectral analyzer (OSA) or a ratiometric interrogation system: (1) if interrogated by an OSA assuming a resolution of 1 pm, it has a sensitivity of 28.2 nm for a displacement measurement range from 0 to 280 μm; (2) if interrogated by a …

Strain Sensor Based On A Pair Of Single-Mode-Multimode-Single-Mode Fiber Structures In A Ratiometric Power Measurement Scheme, Agus Hatta, Yuliya Semenova, Qiang Wu, Gerald Farrell

Articles

The strain and temperature dependencies of a step-index single-mode–multimode–single-mode (SMS) fiber structure are investigated numerically and experimentally. For intensity-based strain measurement using a single SMS fiber structure, at a selected wavelength, it is found that there is a high strain dependence, but also a temperature dependence that will induce strain measurement error. To minimize the temperature-induced strain measurement error, two SMS fiber structures are proposed and demonstrated in a ratiometric power measurement scheme; one SMS structure acts as the strain sensor, and the other SMS structure acts as the temperature monitor. The extracted temperature information is used to determine a …

Electron-Electron Scattering In A Double Quantum Dot: Effective Mass Approach, S. Yu. Kruchinin, A. V. Federov, A. V. Baranov, Tatiana Perova, Kevin Berwick

Articles

We present a theoretical description of the first-order scattering of interacting electrons and holes in a double quantum dot. Assuming infinitely high walls, strong confinement, and a two-band approximation, we derive general expressions for the two-particle matrix elements of the screened Coulomb potential. We also determine the selection rules for different scattering channels and consider special cases where the corresponding matrix elements can be represented by simple analytical expressions. Numerical calculations of the matrix elements and an analysis of their dependence on the geometrical and material parameters of the double quantum dot have also been performed.

A Voltage Sensor Based On A Singlemode-Multimode-Singlemode Fiber Structure, Agus Hatta, Yuliya Semenova, Ginu Rajan, Gerald Farrell

Articles

A voltage sensor based on a singlemode-multimodesinglemode (SMS) fiber structure, attached to a piezoelectric (PZT), utilized in a ratiometric optical power measurement scheme is proposed. The elongation of the PZT due to an applied voltage induces a strain on the SMS fiber structure and in turn results in a change in the transmission loss response of the SMS fiber structure. It is found that at selected wavelengths, a strong voltage dependence for the transmission loss of the SMS fiber structure can be achieved. The voltage information can be obtained from the power ratio of the system, assuming the system is …

Corporate Social Responsibility And The Future Healthcare Manager, Sandra Collins

Articles

The decisions and actions of healthcare managers are often times heavily scrutinized by the public. Given the current economic climate, managers may feel intense pressure to produce higher results with fewer resources. This could inadvertently test their moral fortitude and their social consciousness. A study was conducted to determine what Corporate Social Responsibility (CSR) Orientation and Viewpoint future healthcare managers may hold. The results of the study indicate that future healthcare managers may hold patient care in high regard as opposed to profit maximization. However, the results of the study also show that future managers within the industry may continue …

Not So Fast! Economic Principles And Across-The-Board Cuts, Roger L. Cross

Articles

The purpose of this paper is to address the irrationality of making budget decisions without awareness of the economic foundation of these decisions. It aims to propose that, in lieu of a universal economic principle, librarians should at least adopt the maxim, “first, do no harm.”

The paper argues the need to review budgetary distribution models in terms of economic principles and the argument incorporates the author's recent implementation of material cuts at his institution. The paper argues that sound economic principles are being ignored in budget decision making. The paper finds that application of across-the-board materials cuts is inequitable …

Graphic Novel Collections In Academic Arl Libraries, Cassie Wagner

Articles

This study examines the extent to which ARL academic libraries collect graphic novels. Using a core list of 176 titles developed from winners of major comics industry awards and a library-focused “best of” list, the holdings of 111 ARL academic libraries were searched using the libraries’ online catalogs. Results suggest that most of the libraries studied do not aggressively collect graphic novels. Also examined were associations between date of publication, prior serialization, overall collection size, monograph budget, and ARL ranking and graphic novel holdings. To better serve scholarly research in this area of increasing interest, libraries will need to reexamine …

History On The Move: Relocating Special Collections And Archives, Pamela S. Hackbart-Dean, Leah Agne, Julie Mosbo

Articles

The focus of this article is on the preparation and execution of a move. In it, we highlight the level of attention to detail entailed, which in turn necessitates an amazing amount of planning. And even then, contingencies arise. We share experiences that demonstrate the likelihood of obstacles along the way, problems to be resolved and the potential scope of post-move recovery projects. A successful move will ensure that the collections are undamaged by either the move or their new surroundings and that they are available to researchers as soon as possible. While the goal is straightforward, the reality can …

Controlling Residential Stakes, Lee Anne Fennell, Julie Roin

Articles

Local communities often suffer when residents have too small a stake in their homes-a point underscored by recent rashes of foreclosures and abandonments, and implicated by longstanding questions about the effects on communities of renters and owner-occupants, respectively. However, homeowners with too great a financial stake in their homes can also cause difficulties for local governance by acting as risk-averse NIMBYs. Local governments should have a strong interest in helping members of their communities move away from problematic forms of stakeholding and toward more desirable intermediate positions. This Article examines how and why governmental entities at the state and local …

Interest Groups And The Problem With Incrementalism, Saul Levmore

Articles

Incrementalism, as opposed to dramatic change, is conventionally lauded in law as the prudent path of change-a path that gives credit to history and precedent. The conventional view, however, pays little attention to interest groups. Step-by-step change poses a serious problem when it rearranges the constellation of supporters and opponents of further moves. The core problem is that once an interest group loses and becomes subject to some regulation, it has reason to turn on its competitors and see to it that they also be regulated. The laws that emerge on the incrementalist's path therefore may not mark progress toward …

Against Feasibility Analysis, Jonathan Masur, Eric A. Posner

Articles

Feasibility analysis, a method of evaluating government regulations, has emerged as the major alternative to cost-benefit analysis. Although regulatory agencies have used feasibility analysis (in some contexts called "technology-based" analysis) longer than cost-benefit analysis, feasibility analysis has received far less attention in the scholarly literature. In recent years; however, critics of cost-benefit analysis have offered feasibility analysis as a superior alternative. We advance the debate by uncovering the analytic structure of feasibility analysis and its normative premises, and then criticizing them. Our account builds on two examples of feasibility analysis, one conducted by OSHA and the other by EPA. We …

The Right To Abandon, Lior Strahilevitz

Articles

The common law prohibits the abandonment of real property. Perhaps it is surprising, therefore, that the following are true: (1) the common law generally permits the abandonment of chattel property, (2) the common law promotes the transfer of real property via adverse possession, and (3) the civil law is widely believed to permit the abandonment of real property. Because the literature on abandonment is disappointingly sparse, these three peculiarities have escaped sustained scholarly analysis and criticism. This Article aims to provide a comprehensive analysis of the law of abandonment. After engaging in such an analysis, this Article finds that the …

Withdrawing From International Custom, Curtis A. Bradley, Mitu Gulati

Articles

Treaties are negotiated, usually written down, and often subject to cumbersome domestic ratification processes. Nonetheless, nations often have the right to withdraw unilaterally from them. By contrast, the conventional wisdom is that nations never have the legal right to withdraw unilaterally from the unwritten rules of customary international law (CIL), a proposition that we refer to as the “Mandatory View.” It is not obvious, however, why it should be easier to exit from treaties than from CIL, especially given the significant overlap that exists today between the regulatory coverage of treaties and CIL, as well as the frequent use of …
