Critical Issues In Software Quality Assurance: An Exploratory Study

Recent reviews of the Software Quality Assurance (SQA) literature expose that in most organizations, systems development is characterized by recurrent problems, such as poor system quality.  The conclusions of these reviews is that SQA efforts have failed due primarily to their failure to adequately address the linkages between the organizational and process aspects of quality assurance in software development projects.  As an initial step in identifying and understanding the linkages between the organizational and process aspects of SQA, the authors conducted an exploratory study to elicit a set of issues critical to the assurance of delivering reliable software

Experiential Profiles: An Instrument For Assessing The Efficacy Of Surrogates For IS Roles

Given both the need for IS professionals as experimental subjects in behavioral research and their limited availability, IS research would be served by determining a way to assess the efficacy of surrogates for IS professionals so that surrogates could be used where appropriate.  Because a single monolithic ‘IS professional’ does not exist, and comparisons of experiential differences must account for how experience shapes a professional’s way of seeing and evaluating the world, the authors identified an instrument for comparing the experiential profile of CIOs to surrogates.  The authors validated the instrument using a group shown in the literature to possess a significantly different experiential profile from CIOs

Understanding and Finding Solutions to the Problem of Sedimentation in the National Wildlife Refuge System

The National Wildlife Refuge System (Refuge System) is a collection of public lands maintained by the U.S. Fish and Wildlife Service for migratory birds and other wildlife. Wetlands on individual National Wildlife Refuges (Refuges) may be at risk of increased sedimentation because of land use and water management practices. Increased sedimentation can reduce wetland habitat quality by altering hydrologic function, degrading water quality, and inhibiting growth of vegetation and invertebrates. On Refuges negatively affected by increased sedimentation, managers have to address complex questions about how to best remediate and mitigate the negative effects. The best way to account for these complexities is often not clear. On other Refuges, managers may not know whether sedimentation is a problem. Decision makers in the Refuge System may need to allocate resources to studying which Refuges could be at risk. Such analyses would help them understand where to direct support for managing increased sedimentation. In this paper, we summarize a case study demonstrating the use of decision-analytic tools in the development of a sedimentation management plan for Agassiz National Wildlife Refuge, Minnesota. Using what we learned from that process, we surveyed other Refuges in U.S. Fish and Wildlife Service Region 3 (an area encompassing the states of Illinois, Indiana, Iowa, Ohio, Michigan, Minnesota, Missouri, and Wisconsin) and Region 6 (an area encompassing the states of Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming) about whether they experience sediment-related impacts to management. Our results show that cases of management being negatively affected by increased sedimentation are not isolated. We suggest that the Refuge System conduct a comprehensive and systematic assessment of increased sedimentation among Refuges to understand the importance of sedimentation in context with other management problems that Refuges face. The results of such an assessment could guide how the Refuge System allocates resources to studying and managing widespread stressors

In de voetsporen van de kritische boerin : 25 jaar Landelijke Boerinnen Belangen, 1983-2008

Het verhaal van 25 jaar Landelijke Boerinnen Belangen (LBB) geeft in een notendop weer hoe kritische boerinnen hun maatschappelijke betrokkenheid vormgaven. Gestimuleerd door de vrouwenbeweging merkten zij in de zeventig jaren van de vorige eeuw dat zij een andere positie hadden dan de meeste vrouwen. Zij waren niet alleen getrouwd met een man die boer van beroep was, maar ook met zijn bedrijf. Niet alleen economisch, maar ook sociaal waren gezin, huishouden en bedrijf zo met elkaar verweven, dat zij hun positie wel in samenhang moesten bekijken. De geschiedenis van LBB toont hun zoektocht naar de tot dan toe onderbelichte positie van vrouwen in de agrarische sector. Deze boerinnen lieten ook zien hoe het landbouwbeleid en de besluitvorming daarover samenhingen met de knelpunten en problemen die zij in de dagelijkse praktijk tegenkwamen. Zij experimenteerden in hun eigen praktijk, vertaalden hun visies naar beleidsalternatieven en brachten die onder de aandacht bij de landbouworganisaties en ministeries. Voor het eerst lieten boerinnen hun stem horen over landbouwzaken waar zij zich toentertijd verre van dienden te houden

Effects of mass waste events on thrust wedges: Analogue experiments and application to the Makran accretionary wedge

Olistostromes cover large portions of active thrust wedges like Makran, Gulf of Cadiz, and offshore Borneo. Olistostrome emplacement by submarine mass flow represents an instantaneous and massive mass redistribution that may influence thrust wedge mechanics. Different scenarios are experimentally tested. They show that the postolistostrome wedge development depends on the thickness and extent of the added load. These results are discussed after the example of the Iranian Makran wedge, situated between the Arabian and Eurasian plates. Mass redistribution caused by a late Miocene mass flow may explain a change in deformation style from intense folding and thrusting to gentle folding and eventually a jump of thrust imbrication toward the frontal offshore part of this active accretionary wedge. © 2010 by the American Geophysical Union

Thermotectonic evolution of an extensional dome: the Cenozoic Osogovo-Lisets core complex (Kraishte zone, western Bulgaria)

The Kraishte region of Bulgaria is located at the junction of the Balkanides and Hellenides-Dinarides tectonic belts. Fission-track analysis on both apatites and zircons documents the Cenozoic exhumation of a Precambrian basement bounded by low-angle detachments. Late Eocene-Oligocene extension began prior to 47Ma and was dominantly in a top-to-the-southwest direction, confirmed by the sense of younging of apatite and zircon ages. This crustal extension controlled the formation of half-graben sedimentary basins on the hanging walls of the detachments. Thermal modelling of these hanging wall units provides evidence for heat transfer across the detachments from a relatively warm rising footwall. From 32 to 29Ma, pervasive magmatic activity resulted in the emplacement of rhyolitic to dacitic subvolcanic bodies and dykes, along with intrusion of the Osogovo granite. The results give evidence for extension in the southern Balkan older than, and separated from, the Miocene to Quaternary Aegean extension. This might reflect transtension during northeastward extrusion and rotation of continental fragments around the western boundary of Moesia. Eocene-Oligocene extension seems to have been controlled by the distribution of earlier thickening all around the Carpatho-Balkanic orocline, which is reflected by the Cretaceous emplacement of the Morava Nappe in the Kraisht
