Critical thresholds, evaluation and regional development

ENVIRONMENTAL POLICY AND GOVERNANCE, Issue 2 2008
Patrick ten Brink
Abstract This paper is part of the Special Issue of European Environment devoted to the outputs of the EU SRDTOOLS project, which developed and applied a new model of regional sustainable development evaluation. This paper introduces as an evaluation criterion the idea of critical thresholds, which up to now have not been sufficiently integrated into thinking and decision making in the context of regional development. Decision making explicitly or implicitly accepts trade-offs across economic, social, human and nature domains. Some of these trade-offs, especially when they may threaten system integrity, are not sufficiently understood. The paper discusses how critical thresholds and trends can be integrated into evaluation methods and provides some insights from practical applications. It concludes that such integration into regional planning and evaluation should support objectives for sustainable development and improve decision making and environmental governance.

From generative fit to generative capacity: exploring an emerging dimension of information systems design and task performance

INFORMATION SYSTEMS JOURNAL, Issue 4 2009
Michel Avital
Abstract Information systems (IS) research has been long concerned with improving task-related performance. The concept of fit is often used to explain how system design can improve performance and overall value. So far, the literature has focused mainly on performance evaluation criteria that are based on measures of task efficiency, accuracy, or productivity. However, nowadays, productivity gain is no longer the single evaluation criterion. In many instances, computer systems are expected to enhance our creativity, reveal opportunities and open new vistas of uncharted frontiers. To address this void, we introduce the concept of generativity in the context of IS design and develop two corresponding design considerations ,,generative capacity' that refers to one's ability to produce something ingenious or at least new in a particular context, and ,generative fit' that refers to the extent to which an IT artefact is conducive to evoking and enhancing that generative capacity. We offer an extended view of the concept of fit and realign the prevailing approaches to human,computer interaction design with current leading-edge applications and users' expectations. Our findings guide systems designers who aim to enhance creative work, unstructured syntheses, serendipitous discoveries, and any other form of computer-aided tasks that involve unexplored outcomes or aim to enhance our ability to go boldly where no one has gone before. In this paper, we explore the underpinnings of ,generative capacity' and argue that it should be included in the evaluation of task-related performance. Then, we briefly explore the role of fit in IS research, position ,generative fit' in that context, explain its role and impact on performance, and provide key design considerations that enhance generative fit. Finally, we demonstrate our thesis with an illustrative vignette of good generative fit, and conclude with ideas for further research. [source]

Long term efficacy of minimal incision osteotomy for hallux abducto valgus

ORTHOPAEDIC SURGERY, Issue 3 2010
Wei-dong Sun MD
Objective:, To observe and evaluate the long-term results of minimal incision osteotomy for hallux abducto valgus. Methods:, From February 1995 to May 1999, 372 cases (705 feet) with hallux abducto valgus were treated with minimal incision osteotomy. Seventy-nine patients (150 feet) were followed up for more than five years (mean 7.5; range, 5.3,13.2 years) after surgery. The preoperative and postoperative hallux abducto valgus angles (HVA), intermetatarsal angles (IMA), tibial sesamoid position (TSP), American Orthopaedic Foot And Ankle Society (AOFAS) score, range of movement of the first metatarsophalangeal joint and lateral metatarsalgia were observed, measured and evaluated. Results:, Based on clinic curative effect evaluation criterion, 56 feet (37.3%) were excellent, 88 feet (58.7%) good, 6 feet (4.0%) fair. The postoperative mean AOFAS score was 84.20 ± 4.32 points. The mean HVA decreased from 33.28o to 12.31o and the mean IMA1-2 from 11.75o to 6.80o. The TSP was corrected from an average preoperative grade of 4.29 to a grade of 3.07 by final follow-up. There was no nonunion or delayed union, no avascular necrosis, no infection, and no hallux varus. Numbness in the big toe was found in 4 feet (2.7%). The range of motion of the first metatarsophalangeal joint decreased from 70.20o to 69.53o. Of 97 feet (64.7%) with pre-operative 2,5 metatarsalgia, this had disappeared in 35 feet, improved in 54 feet and was aggravated in 8 feet postoperatively. Conclusion:, Minimal incision osteotomy is a simple and reliable technique for treating hallux abducto valgus with minimal complications. [source]

Semantic Retrieval in DNA-Based Memories with Gibbs Energy Models

BIOTECHNOLOGY PROGRESS, Issue 1 2006
Andrew Neel
At least three types of associative memories based on DNA-affinity have been proposed. Previously, we have quantified the quality of retrieval of genomic and abiotic information in simulation by comparison to state-of-the-art symbolic methods available, such as LSA (Latent Semantic Analysis). Their performance is poor when the evaluation criterion for DNA-affinity is a simple approximation of the Gibbs energy that governs duplex formation for retrievals. Here, we use a more realistic approximation of the Gibbs energy to improve semantic retrievals in DNA memories. Their performance is much closer to that of LSA, according to human expert ratings. With more realistic approximations of DNA affinity, performance is expected to improve for other, more adaptive associative memories with compaction in silico, and even more so with actual DNA molecules in vitro.
