Additive Maps Preserving The Reduced Minimum Modulus Of Banach Space Operators, Abdellatif Bourhim

Mathematics - All Scholarship

Let B(X) be the algebra of all bounded linear operators on an infinite dimensional complex Banach space X. We prove that an additive surjective map phi on B(X) preserves the reduced minimum modulus if and only if either there are bijective isometries U:X -> X and V:X -> X both linear or both conjugate linear such that phi(T)=UTV for all T in B(X), or X is reflexive and there are bijective isometries U:X^* -> X and V:X -> X^* both linear or both conjugate linear such that phi(T)=UT^*V for all T in B(X). As immediate consequences …

Relationship Of Reef Fish Assemblages And Topographic Complexity On Southeastern Florida Coral Reef Habitats, Brian K. Walker, Lance K. B. Jordan, Richard E. Spieler

Marine & Environmental Sciences Faculty Articles

Reef fish assemblage relationships with in situ and lidar topographic measurements across the seascape were analyzed to evaluate the possibility of using lidar metrics as a proxy for prediction models. In situ topographic complexity (i.e., linear rugosity) was measured from 346 point-count fish surveys spanning the reef seascape. Lidar topographic measurements (i.e., surface rugosity, elevation, and volume) were obtained from a high-resolution lidar bathymetric dataset of each survey's footprint. The survey sites were characterized by an independently derived benthic habitat map. Reef fish abundance and species richness appeared to increase with increasing topographic complexity. Although significant, the relationship was weak. …

Equal Access: A National Comparison Of Federal Grants-In-Aid Awarded At Public And Private Four-Year Degree Granting Institutions, Lee Waller, Sandra Weeks, Steven Westbrook, Karl Payton

Academic Leadership: The Online Journal (2003-2012)

More than twelve million undergraduate students in the United States benefit from some form of financial aid. Statistics from the U.S. Department of Education (as cited in The American Council of Education 2008) indicate that 76% of undergraduates at public four-year degree-granting institutions during the 2003-2004 academic year received financial aid, while 89% of undergraduate students at private four-year not-for-profit degree-granting institutions were aid recipients.

Identifying And Alleviating Stress Of Teacher Candidates In A Secondary Professional Development Schools (Pds) Program, Molly Mee

Academic Leadership: The Online Journal (2003-2012)

Teacher candidate stress is a significant issue for candidates, students, mentor teachers, and the Institute of Higher Education (IHE) representatives who work with the candidates. Stress during this important stage in a new teacher’s career can be detrimental in many ways from causing early burnout (Greer & Greer, 1992; Schwab, 1989) to attrition (Brownell, 1997) and absenteeism. “It is during student teaching that preservice teachers begin to learn the habits of the profession and begin to develop adaptive or maladaptive coping skills for dealing with the stress of teaching” (Gold, 1985; Greer & Greer, 1992 as cited in Fives, Hamman, …

Influence Of Test Anxiety On Performance Levels On Numerical Tasks Of Secondary School Physics Students, Bimbola Oludipe

Academic Leadership: The Online Journal (2003-2012)

The purpose of the current study was to identify teacher behaviors that secondary students perceived as demonstrating caring. The questions that guided this inquiry were (a) what teacher behaviors do high school students perceive as caring? and (b) what teacher behaviors do high school students perceive as the most important aspects of caring? Whereas previous studies clearly have documented the power and influence of caring teachers on adolescents’ success, we posit that knowing what students perceive as caring behaviors can be used as a springboard to shape the context of caring for all students, especially those who are marginalized, feel …

Successful Leadership In Turnaround Schools: A Case Study About The Center For Creative Leadership (Ccl) And The School Leadership Executive Institute (Slei), Belinda B. Mcfeeters, Emily Hoole

Academic Leadership: The Online Journal (2003-2012)

The topic of turning failing schools around has gained significant attention throughout the world within the last decade. Accountability systems from the government to the general community have expressed their concern for this issue, and have called for plans to turn these schools around (Chapman, 2002; Hassel & Steiner, 2003; Levin, 2006; Malen & Rice, 2004; Wong & Shen, 2003). How do principals meet these challenges and successfully turn failing schools around? How can they gain the insight, knowledge and competencies to effectively lead their schools through these challenging times?

What Is Rigor?: A Qualitative Analysis Of One School’S Definition, Heather Bower, Joelle Powers

Academic Leadership: The Online Journal (2003-2012)

In an era of increasing accountability, school administrators and faculties often find themselves amid a plethora of best practices and strategies aimed at improving students’ academic achievement. In the midst of these discussions, school culture is often hailed as the key to creating effective schools because it defines how people within a particular school are to behave and what they are to value (Stolp & Smith, 1995). Furthermore, it allows administrators to draw attention to some of the culture’s most important aspects: its values, beliefs, and assumptions that create the school’s vision for excellence (Stolp & Smith, 1995). Malloy (2005) …

Rotating-Term Associate Deans: Pathway To Higher Education Administration, Eugenia Gerdes, Christopher Zappe

Academic Leadership: The Online Journal (2003-2012)

In a recent article in this journal, Betts, Urias, Chavez, and Betts (2009) argue that higher education faces a leadership shortage—due both to expected turnover in senior administrative positions and to lack of clear pathways into administration. As we have discussed elsewhere (Zappe & Gerdes, 2008), administration is not typically a long-term goal for those whose careers begin with faculty appointments. For the few who switch pathways to become academic administrators, an associate dean position often is the point of transition. Below, we describe the advantages of rotating associate dean positions, in which faculty members from the same institution leave …

Structure Of The Photochemical Reaction Path Populated Via Promotion Of Cf2i2 Into Its First Excited State, Patrick Z. El-Khoury, Alexander N. Tarnovsky, Igor Schapiro, Mikhail N. Ryazantsev, Massimo Olivucci

Chemistry Faculty Publications

The photochemical reaction path following the promotion of CF2I2 into its lowest-lying excited electronic singlet state has been modeled using ab initio multiconfigurational quantum chemical calculations. It is found that a conical intersection drives the electronically excited CF2I2* species either to the CF2I + I radical pair or back to the starting CF2I2 structure. The structures of the computed relaxation pathways explain the photoproduct selectivity previously observed in the gas phase. Furthermore, the results provide the basis for explaining the condensed-phase photochemistry of CF2I2.

A Semi-Parametric Two-Stage Projection Type Estimator Of Multivalued Treatment Effects, Aurobindo Ghosh

Research Collection School Of Economics

One of the most well documented regularities in evaluation literature like returns to schooling(or funding for programs) is that several factors come together to confound the measurement of its effect. First, in observational studies the true return is often individual specific, and so it is almost impossible to use a traditional treatment effect models with randomly assigned treatment and control groups. This endogeneity in the model further exacerbates our inability to conduct such trials. Second, the problem is not a classical treatment effect measurement problem where we have discrete or more often binary treatments. Hence, techniques like measuring the Local …

Reinforcing The Number Of Disjoint Spanning Trees, Damin Liu, Hong-Jian Lai, Zhi-Hong Chen

Scholarship and Professional Work - LAS

The spanning tree packing number of a connected graph G, denoted by _T(G), is the maximum number of edge-disjoint spanning trees of G. In this paper, we determine the minimum number of edges that must be added to G so that the resulting graph has spanning tree packing number at least k, for a given value of k.

Sdss J102347.6+003841: A Millisecond Radio Pulsar Binary That Had A Hot Disk During 2000-2001, Zhongxiang Wang, Anne M. Archibald, John R. Thorstensen, Victoria M. Kaspi

Dartmouth Scholarship

The Sloan Digital Sky Survey (SDSS) source J102347.6+003841 was recently revealed to be a binary 1.69 ms radio pulsar with a 4.75 hr orbital period and a ~0.2 M _☉ companion. Here, we analyze the SDSS spectrum of the source in detail. The spectrum was taken on 2001 February 1, when the source was in a bright state and showed broad, double-peaked hydrogen and helium lines—dramatically different from the G-type absorption spectrum seen from 2002 May onward. The lines are consistent with emission from a disk around the compact primary. We derive properties of the disk by fitting the SDSS …

A Preferential Tableaux Calculus For Circumscriptive Alco, Stephan Grimm, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Nonmonotonic extensions of description logics (DLs) allow for default and local closed-world reasoning and are an acknowledged desired feature for applications, e.g. in the Semantic Web. A recent approach to such an extension is based on McCarthy's circumscription, which rests on the principle of minimising the extension of selected predicates to close off dedicated parts of a domain model. While decidability and complexity results have been established in the literature, no practical algorithmisation for circumscriptive DLs has been proposed so far. In this paper, we present a tableaux calculus that can be used as a decision procedure for concept satisfiability …

Interpretation Of Single-Beam Acoustic Backscatter Using Lidar-Derived Topographic Complexity And Benthic Habitat Classifications In A Coral Reef Environment, Greg Foster, Brian K. Walker, Bernhard Riegl

Marine & Environmental Sciences Faculty Articles

Producing thematic coral reef benthic habitat maps from single-beam acoustic backscatter has been hindered by uncertainties in interpreting the acoustic energy parameters E1 (tail of 1st echo) and E2 (complete 2nd echo), typically limiting such maps to sediment classification schemes. In this study, acoustic interpretation was guided by high-resolution lidar (LIght Detection And Ranging) bathymetry. Each acoustic record, acquired from a BioSonics DT-X echosounder and multiplexed 38 and 418 kHz transducers, was paired with a spatially-coincident value of a lidar-derived proxy for topographic complexity, reef-volume (RV), and its membership to one of eight benthic habitat classes, delineated from lidar imagery, …

Advanced Mid-Water Tools For 4d Marine Data Fusion And Visualization, Maurice Doucet, Colin Ware, Thomas C. Weber, Larry A. Mayer, Roland J. Arsenault, Mashkoor A. Malik, Lindsay Gee

Center for Coastal and Ocean Mapping

Mapping and charting of the seafloor underwent a revolution approximately 20 years ago with the introduction of multibeam sonars -- sonars that provided complete, high-resolution coverage of the seafloor rather than sparse measurements. The initial focus of these sonar systems was the charting of depths in support of safety of navigation and offshore exploration; more recently innovations in processing software have led to approaches to characterize seafloor type and for mapping seafloor habitat in support of fisheries research. In recent years, a new generation of multibeam sonars has been developed that, for the first time, have the ability to map …

Understanding Delivery Routes In Urban Areas, Miguel Figliozzi

TREC Project Briefs

Supply chains and urban areas cannot thrive without the efficient movement of goods. A recent study indicates that commercial vehicles carrying goods or providing services account for, on average, almost 10 percent of the total vehicle miles traveled (VMT) in medium to large urban areas. A predominant share of these trips takes place within a multi-stop tour. In order to develop a well-organized system for moving freight through urban areas, it is crucial to understand and quantify how routes and distribution decisions affect commercial vehicle flows and VMTs.

In the past, transportation planning models have focused on passenger movements but …

Enhancing Ais To Improve Whale-Ship Collision Avoidance And Maritime Security, Philip A. Mcgillivary, Kurt Schwehr, Kevin Fall

Center for Coastal and Ocean Mapping

Whale-ship strikes are of growing worldwide concern due to the steady growth of commercial shipping. Improving the current situation involves the creation of a communication capability allowing whale position information to be estimated and exchanged among vessels and other observation assets. An early example of such a system has been implemented for the shipping lane approaches to the harbor of Boston, Massachusetts where ship traffic transits areas of the Stellwagen Bank National Marine Sanctuary frequently used by whales. It uses the Automated Identification Systems (AIS) technology, currently required for larger vessels but becoming more common in all classes of vessels. …

Broadband Records Of Earthquakes In Deep Gold Mines And A Comparison With Results From Safod, California, Art Mcgarr, Margaret S. Boettcher, Jon Peter B. Fletcher, R Sell, Malcolm J. Johnston, R Durrheim, S Spottiswoode, A Milev

Center for Coastal and Ocean Mapping

For one week during September 2007, we deployed a temporary network of field recorders and accelerometers at four sites within two deep, seismically active mines. The ground-motion data, recorded at 200 samples/sec, are well suited to determining source and ground-motion parameters for the mining-induced earthquakes within and adjacent to our network. Four earthquakes with magnitudes close to 2 were recorded with high signal/noise at all four sites. Analysis of seismic moments and peak velocities, in conjunction with the results of laboratory stick-slip friction experiments, were used to estimate source processes that are key to understanding source physics and to assessing …

A Proposal For 'Philosophical Method' In Comparative And International Law, John Martin Gillroy

Pace International Law Review Online Companion

A basic challenge of contemporary thought is to better understand the origin, persistence, and future course of international/ comparative law. I suggest that a foundational step is to begin treating the law as a philosophical matter. I propose that comparative and international legal theory require a distinct methodology that is as integrated and systematic as positivism, but which better recognizes the dialectic interdependence of normative and empirical and the metaphysical interdependence of theory and practice. Philosophical Method, as systematized by R.G. Collingwood, promotes the dialectic over the eristic, looks for overlap rather than definitive scientific classification, argues for comprehensive philosophy …
