On the quest for multi-methods in IS evaluation: a qualitative comparative analysis

This paper responds to calls for new approaches to IS evaluation. It does this by introducing fuzzy-set Qualitative Comparative Analysis as a new IS evaluation approach that augments the qualitative tradition by supporting cross-case analysis and theory development. Rather than disaggregating cases into independent, analytically-separate variables, fuzzy-set Qualitative Comparative Analysis advocates an approach to IS evaluation which explores the holistic effects of causal conditions working in conjunction with each other. The paper uses qualitative coding procedures and fuzzy-set Qualitative Comparative Analysis in a sequential manner to discover two typologies of monitoring systems success based on automated and manual validations respectively. Theoretical, methodological and practical implications of the use of fuzzy-set Qualitative Comparative Analysis are discussed in the context of a multi-case evaluation of monitoring systems established in the course of the implementation of a major European Union socio-economic support programme

Millennial‐Scale Vulnerability of the Antarctic Ice Sheet to Regional Ice Shelf Collapse

The response of the Antarctic Ice Sheet to ice shelf collapse is explored with a high resolution ice sheet model. Rapid melting is applied to each of its major present day drainage basins in turn , to determine which parts of the ice sheet are most vulnerable to change in oceanic forcing, over the next 1000 years. We findthat West Antarctica can be largely deglaciated over a millenium, leading to more than two metres of sea level rise, if any of its major ice shelved disintegrated. The response of East Antarctica is more muted, but not negligible

Ongoing over-exploitation and delayed responses to environmental change highlight the urgency for action to promote vertebrate recoveries by 2030

To safeguard nature, we must understand the drivers of biodiversity loss. Time-delayed biodiversity responses to environmental changes (ecological lags) are often absent from models of biodiversity change, despite their well-documented existence. We quantify how lagged responses to climate and land-use change have influenced mammal and bird populations around the world, while incorporating effects of direct exploitation and conservation interventions. Ecological lag duration varies between drivers, vertebrate classes and body size groupings-e.g. lags linked to climate-change impacts are 13 years for small birds, rising to 40 years for larger species. Past warming and land conversion generally combine to predict population declines; however, such conditions are associated with population increases for small mammals. Positive effects of management (>+4% annually for large mammals) and protected areas (>+6% annually for large birds) on population trends contrast with the negative impact of exploitation (<-7% annually for birds), highlighting the need to promote sustainable use. Model projections suggest a future with winners (e.g. large birds) and losers (e.g. medium-sized birds), with current/recent environmental change substantially influencing abundance trends to 2050. Without urgent action, including effective conservation interventions and promoting sustainable use, ambitious targets to stop declines by 2030 may already be slipping out of reach

Flow-driven transition and associated velocity profiles in a nematic liquid-crystal cell

S. A. Jewell, S. L. Cornford, F. Yang, P. S. Cann, and J. R. Sambles, Physical Review E, Vol. 80, article 041706 (2009) "Copyright © 2009 by the American Physical Society."The alignment properties and distribution of flow speed during Poiseuille flow through a microchannel of a nematic liquid crystal in a cell with homeotropic surface alignment has been measured using a combination of conoscopy, fluorescence confocal polarizing microscopy, and time-lapse imaging. Two topologically distinct director profiles, with associated fluid velocity fields, are found to exist with the preferred state dictated by the volumetric flow rate of the liquid crystal. The results show excellent agreement with model data produced using the Ericksen-Leslie nematodynamics theory

Evolution and Sedimentary History of the Cape Bojador Continental Margin, Northwestern Africa

The Cape Bojador region of the northwestern African continental margin is apparently an unusual passive margin setting. Climatic fluctuations, local volcanism, and possibly tectonics have played important roles in the sedimentary record in this region. A transect of drilling sites connected by seismic profiles is available from the coastal Aaiun Basin (CORC 15-1), across the shelf (Spansah 51A-1), on the continental slope (DSDP Site 369), the upper continental rise (DSDP Site 397), farther out on the rise (e.g., DSDP Sites 139 and 140), and the abyssal plain (DSDP Sites 137 and 138). These data allow construction of a profile perpendicular to the margin, and reconstruction of the sedimentary evolution there

El Fundamento Mítico de la (Des)Igualdad en la Politeia de Platón

RESUMEN:El siguiente escrito ensaya una interpretación del rendimiento del mito de los metales expuesto por Platón en su diálogo llamado Politeia a propósito de la siguiente interrogación: ¿Cómo se constituye el orden social en la pólis platónica? Para responder a esta pregunta debemos esclarecernos respecto de: i) El papel de la educación en la constitución del orden social. ii) La correlación entre el mito de los metales y el orden social. iii) La constitución tripartita de la psykhḗ humana. Una vez aclarado estos distintos puntos podremos comprender la oculta pero significativa función del mito de los metales en la constitución del orden social platónico

First urology simulation boot camp in the United Kingdom

Objective: Simulation is now firmly established in modern surgical training and is applicable not only to acquiring surgical skills but also to non-surgical skills and professionalism. A 5-day intensive Urology Simulation Boot Camp was run to teach emergency procedural skills, clinical reasoning, and communication skills using clinical scenario simulations, endoscopic and laparoscopic trainers. This paper reports the educational value of this first urology boot camp. Subjects and methods: Sixteen urology UK trainees completed pre-course questionnaires on their operative experience and confidence level in common urological procedures. The course included seven modules covering basic scrotal procedures, laparoscopic skills, ureteroscopy, transurethral resection of the prostate and bladder tumour, green light laser prostatectomy, familiarisation with common endoscopic equipment, bladder washout to remove clots, bladder botox injection, setting up urodynamics. Emergency urological conditions were managed using scenarios on SimMan®. The main focus of the course was hands-on training using animal models, bench-top models and virtual reality simulators. Post-course assessment and feedback on the course structure and utility of knowledge gained together with a global outcome score was collected. Results: Overall all the sections of feedback received score of over 4.5/5, with the hands-on training on simulators getting the best score 4.8/5. When trainees were asked “The training has equipped me with enhanced knowledge, understanding and skills,” the average score was 4.9/5.0. The vast majority of participants felt they would recommend the boot camp to future junior trainees. Conclusion: This first UK Urology Simulation Boot Camp has demonstrated feasibility and effectiveness in enhancing trainee’s experience. Given these positive feedbacks there is a good reason to expect that future courses will improve the overall skills of a new urology trainee
