The Great Hurricane and Tidal Wave of 1938: Scenes of the Disaster in Rhode Islandâs East Bay
In September of 1983 a hurricane swept across New England. It was one of the most destructive storms to ever strike the region, causing damage in New York, Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine
The Proposed Federal Securities Code: Time to Recognize That Financial Information Becomes Stale
This note addresses the Federal Securities Code ( Code ), developed by the American Law Institute ( ALI ). It specifically focuses on the underlying policy of continuous disclosure implemented by the Code, which requires companies to register once and then continuously disclose to the securities marketplace important developments on their financial position. This note poses a question: At what point does financial information become stale? It focuses on the nature of stale financial information by reviewing the treatment of staleness in common law fraud and bankruptcy cases. It then analyzes the approach taken with regard to stale financial information in existing securities law. Finally, it concludes by proposing that an objective definition of staleness should be incorporated into the Code, placing reasonable limits on the liability created under the Code\u27s continuous disclosure requirements
Fire and rescue service community safety initiatives: measuring impact
Purpose - The purpose of this paper is to discuss methods of capturing the impact of fire and rescue service (FRS) community safety work which directly aims to reduce the occurrence of specific incidents. Design/methodology/approach - The impact assessment method described focuses on addressing one of the major problems with regards to attributing outcomes to FRS community safety work; the influence of external factors. This paper looked to assess the incident trends within a case study UK FRS within the context of the following external data sets: first, incident trends within other UK FRSs; second, demographic trends; and third, incident data from other public services. Findings - There were instances, either across the whole region served by the case study FRS, or within specific districts, where evidence suggested a strong likelihood of the community safety work of the case study FRS contributing towards an observed reduction in incidents. These findings were established through filtering the impact of widespread external factors, which could impact upon incident figures. Research limitations/implications - The utility of this impact assessment relies upon FRS consistently recording the specific aims and focus of individual community safety activity, so that any positive outcomes can be attributed to a particular group of community safety initiatives. Originality/value - This paper discusses how an evaluation process, to deter mine the likelihood of community safety impacting upon incident numbers, can be practically applied to a FRS
Remarks on explicit strong ellipticity conditions for anisotropic or pre-stressed incompressible solids
We present a set of explicit conditions, involving the components of the elastic stiffness tensor, which are necessary and sufficient to ensure the strong ellipticity of an orthorhombic incompressible medium. The derivation is based on the procedure developed by Zee & Sternberg (Arch. Rat. Mech. Anal., 83, 53-90 (1983)) and, consequently, is also applicable to the case of the homogeneously pre-stressed incompressible isotropic solids. This allows us to reformulate the results by Zee & Sternberg in terms of components of the incremental stiffness tensor. In addition, the resulting conditions are specialized to higher symmetry classes and compared with strong ellipticity conditions for plane strain, commonly used in the literature.The first authorâs work and the second authorâs visit to Brunel University were partly supported by

Embedded Eigenvalues and the Nonlinear Schrodinger Equation
A common challenge to proving asymptotic stability of solitary waves is
understanding the spectrum of the operator associated with the linearized flow.
The existence of eigenvalues can inhibit the dispersive estimates key to
proving stability. Following the work of Marzuola & Simpson, we prove the
absence of embedded eigenvalues for a collection of nonlinear Schrodinger
equations, including some one and three dimensional supercritical equations,
and the three dimensional cubic-quintic equation. Our results also rule out
nonzero eigenvalues within the spectral gap and, in 3D, endpoint resonances.
The proof is computer assisted as it depends on the sign of certain inner
products which do not readily admit analytic representations. Our source code
is available for verification at

An Action Research Study on Using Cooperative Learning During Graphic Design Classroom Crits
The author of this action research study surveyed both graphic design students and graphic design instructors about their critique experiences to discover instructors and students both identified a lack of student participation as well as the issue of students getting hurt feelings and becoming discouraged as common critique concerns. The author designed and implemented a treatment called Design Structures to increase student participation during crits. To improve the quality of experience of design students during crits, the author incorporated cooperative learning strategies developed by Spencer and Miguel Kagan (2009) into the Design Structures treatment. The author used the experience sampling method (Csikzentmihalyi, Rathunde, & Whalen, 1993) to compare the quality of experience of community college design students during whole-class crits and during Design Structures crits. Quality of experience levels were consistently higher overall for students during cooperative learning -specifically in the areas of self-esteem, perceived importance of task, challenge, and skill. Furthermore, more design students were in flow and less apathetic during decentralized crits using Design Structures than centralized crits utilizing teacher-led whole-class instruction. In fact, results showed no design students as apathetic during Design Structures crits. The author interviewed design instructors to discover their perceptions, as well as misconceptions, of cooperative learning methodology in addition to their openness to learning more about how to effectively incorporate cooperative learning into their critique pedagogy
