GRADES - A Computer Based Score Management System For the IIgs

This project involved the creation of an electronic gradebook designed to realistically meet the needs of classroom teachers. The computer source code was written in Pascal, a compiled language that allowed fast execution of any part of the program. The electronic gradebook called GradeS uses the graphic Desktop Intert\u27ace. It tracks up to 42 students per class, allowing up to 50 assignments per grading period. An unlimited number of classes can be stored on data disks. It produces four different types of whole class and individual student reports both on the screen and the printer. The project includes a report on the development of the program along with comparisons to existing gradebook programs. The total source code is included, along with annotations describing the function of each unit of the program. Finally, a training/reference manual completes the documentation

A proteasome-resistant fragment of NIK mediates oncogenic NF-κB signaling in schwannomas

Schwannomas are common, highly morbid and medically untreatable tumors that can arise in patients with germ line as well as somatic mutations in neurofibromatosis type 2 (NF2). These mutations most commonly result in the loss of function of the NF2-encoded protein, Merlin. Little is known about how Merlin functions endogenously as a tumor suppressor and how its loss leads to oncogenic transformation in Schwann cells (SCs). Here, we identify nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-inducing kinase (NIK) as a potential drug target driving NF-κB signaling and Merlin-deficient schwannoma genesis. Using a genomic approach to profile aberrant tumor signaling pathways, we describe multiple upregulated NF-κB signaling elements in human and murine schwannomas, leading us to identify a caspase-cleaved, proteasome-resistant NIK kinase domain fragment that amplifies pathogenic NF-κB signaling. Lentiviral-mediated transduction of this NIK fragment into normal SCs promotes proliferation, survival, and adhesion while inducing schwannoma formation in a novel in vivo orthotopic transplant model. Furthermore, we describe an NF-κB-potentiated hepatocyte growth factor (HGF) to MET proto-oncogene receptor tyrosine kinase (c-Met) autocrine feed-forward loop promoting SC proliferation. These innovative studies identify a novel signaling axis underlying schwannoma formation, revealing new and potentially druggable schwannoma vulnerabilities with future therapeutic potential

Chemopreventative celecoxib fails to prevent schwannoma formation or sensorineural hearing loss in genetically engineered murine model of neurofibromatosis type 2

Mutations in the tumor suppressor gene NF2 lead to Neurofibromatosis type 2 (NF2), a tumor predisposition syndrome characterized by the development of schwannomas, including bilateral vestibular schwannomas with complete penetrance. Recent work has implicated the importance of COX-2 in schwannoma growth. Using a genetically engineered murine model of NF2, we demonstrate that selective inhibition of COX-2 with celecoxib fails to prevent the spontaneous development of schwannomas or sensorineural hearing loss in vivo, despite elevated expression levels of COX-2 in Nf2-deficient tumor tissue. These results suggest that COX-2 is nonessential to schwannomagenesis and that the proposed tumor suppressive effects of NSAIDs on schwannomas may occur through COX-2 independent mechanisms

Purpose vs performance : what does marine protected area success look like?

Marine protected areas (MPAs) are an increasingly deployed spatial management tool. MPAs are primarily designed for biodiversity conservation, with their success commonly measured using a narrow suite of ecological indicators. However, for MPAs to achieve their biodiversity conservation goals they require community support, which is dependent on wider social, economic and political factors. Despite this, research into the human dimensions of MPAs continues to lag behind our understanding of ecological responses to MPA protection. Here, we explore stakeholders’ perceptions of what MPA success is. We conducted a series of semi-structured interviews and focus groups with a diverse group of stakeholders local to a South Australian MPA. What constitutes success varied by stakeholder group, and stakeholders’ stated understanding of the purpose of the MPA differed from how they would choose to measure the MPA’s success. Indeed, all interviewees stated that the primary purpose of the MPA was ecological, yet almost all (>90%) would measure the success of the MPA using social and economic measures, either exclusively or in conjunction with ecological ones. Many respondents also stated that social and economic factors were key to the MPA achieving ongoing/future success. Respondents generated a large range of novel socio-economic measures of MPA success, many of which could be incorporated into monitoring programs for relatively little additional cost. These findings also show that success is not straightforward and what constitutes success depends on who you ask. Even where an MPA’s primary ecological purpose is acknowledged by stakeholders, stakeholders are likely to only consider the MPA a success if its designation also demonstrates social and economic benefits to their communities. To achieve local stakeholder support MPAs and associated monitoring programs need to be designed for a variety of success criteria in mind, criteria which reflect the priorities and needs of the adjacent communities as well as national and international conservation objectives

Vertical Zoning in Marine Protected Areas: Ecological Considerations for Balancing Pelagic Fishing with Conservation of Benthic Communities

Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic fishing be compatible with the conservation goals of an MPA that is primarily focused on benthic Communities? In 2005, an expert workshop of fisheries biologists, marine ecologists, MPA managers, and recreational fishermen was convened by NOAAs National MPA Center to evaluate the limited empirical data on benthic-pelagic coupling and to help provide practical advice on this topic. The participants (i) proposed a preliminary conceptual framework for addressing vertical zoning, (ii) developed preliminary guidelines to consider when evaluating whether to allow or restrict pelagic fishing in an MPA, and (iii) identified future research priorities for understanding benthic-pelagic Coupling. A Suite of ecological conditions where recreational pelagic fishing may not be compatible with benthic conservation were identified: (1) high relief habitats, (2) depths shallower than 50-100 m (depending upon the specific location), (3) major topographic and oceanographic features, and (4) spawning areas. Similarly, pelagic fishing is not likely to affect benthic communities adversely in many circumstances. Until further scientific study can shed more light on the issue of how benthic-pelagic linkages affect specific conservation targets, the proposed framework in this manuscript provides practical, easily-applied guidance for using vertical zoning to manage fishing in multiple use MPAs that focus on benthic conservation.Areas Marinas Protegidas (AMP) idealmente, administran el uso humano que amenaza los ecosistemas o sus componentes. Durante el actual proceso de declaracion de AMP, han surgido algunas preocupaciones acerca de la justificacion cientifica para establecer areas de no pesca, particularmente aquellas que restringen la pesca recreativa de especies pelagicas. Una pregunta importante es QQQ ?bajo que condiciones la pesca pelagica recreativa es compatible con los objetivos de conservacion de un AMP que se enfoca principalmente en comunidades bentonicas? En 2005, un taller de expertos en biologia pesquera, ecologfa marina, manejo de AMP y Pescadores recreativos fue convocado por el Centra Nacional de AMP de la NOAA para evaluar los pocos datos empiricos del acoplamiento entre los sistemas pelagico y bentonico, y ofrecer asesoria practica sobre el tema. Los participantes (i) propusieron un marco conceptual preliminar para abordar el tema de la zonacion vertical, (ii) desarrollar directrices preliminares para que cuando se haga una evaluation si se permite o restringe la pesca pelagica dentro de la AMP, y (iii) identificar futuras lineas de investigation para comprender mejor el acoplamiento entre el bentos y el sistema pelagico. Se identifico una serie de condiciones ecologicas en las que la pesca recreativa pelagica puede no ser compatible con la conservacion del bentos: (1) habitat de alto relieve, (2) profundidades menores a 50 m-100 m (dependiendo de la zona), (3) caracteristicas oceanograficas y topograficas sobresalientes, y (4) areas de desove. De igual forma, bajo varias circunstancias, la pesca pelagica puede no afectar las comunidades bentonicas. Hasta que los estudios cientificos brinden mas information acerca de como las relaciones entre el bentos y el ambiente pelagico afectan los objetivos especificos de la conservacion, el contexto propuesto en este trabajo provee una guia practica y de facil aplicacion para utilizar la zonacion vertical en el manejo pesquero en varios aspectos de las AMP que se enfocan en la conservacion del bentos.Keywords: Trophic level, Marine protected areas, Pelagic fisheries, Conservatio

Visualizing the Three-Demensional Footprint of Ocean Uses: A Guide to Building and Applying Space Use Profiles for Ocean Management

The Need for a More Holistic View of Space Requirements of Ocean Uses America’s ocean is becoming increasingly crowded with human activities. More than half the U.S. population lives near the ocean, and millions of people visit the coasts to recreate every year. Additionally, ocean industries, including fishing, shipping, aquaculture, tourism, mining, and energy production, continue to grow and seek new operating areas. Ocean uses can create social and economic benefits to coastal communities and the nation. However, their growing footprint on the seascape also poses challenges for planners, managers and stakeholders who are responding to this trend, especially in areas where multiple distinct uses are operating together. Ocean uses are typically depicted and managed either as simple shapes on a map showing the use’s maximum spatial extent, or, as conceptual cross-sectional illustrations of the use in a general ocean setting. These inherently “flat” and often qualitative perspectives cannot fully quantify or convey the three-dimensional footprint of the entire use across ocean space. Effective ocean planning requires new ways to document, visualize, and understand how any use operates in, on, and under the water, and how that resulting three-dimensional footprint affects other use
