A group of researchers, mosquito and coastal managers, and consultants joined together to explore issues of concern to coastal and mosquito management in mangrove forests. At a 1-day workshop in ...Florida, participants identified issues that are important for their roles. The issues were subsequently compiled into a matrix and the participants were asked to individually assess the importance and urgency of each. The most important issues for everyone included habitat responses to management, community attitude, public education, interaction between agencies, local connectivity, sea-level rise (SLR) loss of wetlands, and conservation. Most urgent were public education, conservation easements, local connectivity, SLR, loss of wetland, restoration, and conservation. There were differing viewpoints among the roles that appeared to be related to responsibility for and ability to influence on-ground outcomes. This is reflected in mosquito and coastal managers who viewed issues broadly and ascribed higher levels of importance and urgency to them than did researchers and consultants. We concluded that collaboration is a key issue. Barriers to collaboration include knowledge differences between agencies. Facilitators of collaboration include interaction, trust, and shared goals.

Journal Article
Odprti dostop
In his article "Software Reuse Myths" from the January 1988 issue of
ACM SIGSOFT Software Engineering Notes,
Will Tracz discusses why software reuse has not grown to its full potential. Engineers ...first proposed the concept of a subroutine library at the University of Cambridge in 1949. Yet the concept has not extended much past this level.At the time Tracz wrote this article, interest had begun to reemerge in the concept of software reuse. Still, Tracz believes that nine myths surround software reuse that have prevented it from becoming more widespread. Specifically, three myths relate to my thesis:1. Software reuse is a technical problem.2. Special tools are needed for software reuse.3. Ada has solved the reuse problem.As far as the first myth goes, the only technical problem is the lack of search methods to find the right pieces of code (which my project should help alleviate). Beyond that, the problem is more psychological, sociological or economic. For example, there is the "Not From Here" attitude pervading industry that Icads people to believe that software developed outside of their company is unreliable.Tracz believes you only need special tools (the second myth) when you become truly serious about reuse. Most software libraries, he claims, are only 100-200 components in size and that programmers can easily navigate this many components without any tools. Also, most instances of reuse occur when a programmer modifies existing programs that either he or a coworker wrote, so again he does not need a tool to find what he needs. I believe that the reuse mentality is a difficult one to accept and any tool that can make the transition to this attitude easier should be explored and utilized, no matter how small the number of components in the software library.Tracz refutes the third myth by stating that "writing a generic package in Ada does not necessarily make it reusable any more than writing a Fortran subroutine or assembly language macro." Simply put, generic packages are not enough to encourage reuse because the packages must still be instantiated with actual data types. The attitudes of the programmers using the language are more important than the language itself in determining whether or not code will be reused. I hope that my project makes Ada more accessible to code reuse and can change some programmers' attitudes about reuse.I believe that this attitude can change if programmers have access to a simple tool to browse software libraries that runs on a variety of hardware platforms to maximize usage and potential. This idea gave rise to ReUSE-WWW, an Ada specification file browser running under Netscape. Since Netscape runs on many platforms (PC, Macintosh, Unix-based., etc.), an application using Netscape as its "operating system" would be ideal. Fortunately, recent developments in World Wide Web programming, such as JavaScript and Perl CGI (Common Gateway Interface) have made this goal extremely attainable.ReUSE-WWW may not run under Microsoft's Internet Explorer, though. It also does not provide any editing, compiling, linking, or running capabilities. I assume that a potential user of the system already has an editor of choice and knows where to get an Ada 95 compiler, such as GNAT.

Abstract only
Over the past three years the University of Scranton has been developing a computer science program. Since we could not hope to obtain the type of equipment, fast processors and ...compilers which many of the larger schools have, we developed several “canned programs” which could accept and act upon student input and give the student some degree of experience with computers which are not within our financial means.
The heart of this development was a simulator we refer to as the SLIC (
S
cranton's
L

omputer) processor. We feel this simulator has a different purpose for its existence than some of the others which have been developed. The original purpose and the one on which we are concentrating in this paper was to give students some practical programming experience on “computers” which have different addressing schemes. We feel SLIC met this original purpose with great success. Its most important contribution to date is in the development of our course in Processor Organization and Assembler Programming. In making this course SLIC dependent, we believe we made it machine independent and as a result we feel we give our students a “feel” for computing which transcends the machine we have on campus.

Conference Proceeding
Program assessment begins with clearly stated and measurable goals and objectives. A set of measurable goals and objectives may always be constructed from the institution's mission statement and the ...ABET/CAC accreditation criteria. There are three constituencies whose input is essential for outcomes assessment-graduating seniors, alumni, organizations that hire our students. A previous paper discusses a senior exit survey. This paper describes the current effort to gather and evaluate information from alumni via a web-based survey. Alumni were made aware of the survey via a bulk mailing. The survey achieved a 20% response rate. A system was constructed to automate the construction of a website that contains the results of the survey. This paper presents an overview of the project.

Conference Proceeding
This paper describes a software resource that is being developed as part of the graduation requirement for the Master in Software Engineering degree at the University of Scranton. This project ...evolved from a series of experiments that were performed in undergraduate and graduate courses at the University. A basic editor was developed as part of an undergraduate course in rapid prototyping. Several students used that project as the basis for undergraduate Senior Projects. All undergraduates are required to complete a project as a degree requirement. This basic editor was handed over to a graduate course in Software Generation and Maintenance and used as the starting point for the construction of various software project management features. The system was constructed to support Ada source code development. However, the system could be readily modified to support source code management in other languages, notably C++. This paper describes the construction of resources that encourage the use of reusable software. Subsequent sections describe the overall framework of the system and selected details that carry out features that make reuse attractive. The system is called
ReUSE
(the

It provides centralized storage of project files, a package browser, automatic function and procedure call creation, a compiler interface, interactive error processing, multiple simultaneous editors, standard windows tools (menus, toolbars, etc.), and other features to help the developer write and reuse Ada code efficiently.ReUSE was developed in Microsoft Visual Basic 4.0 (32-bit) for the Windows 95 / NT operating systems.
