Dynamic stochastic copula models: estimation, inference and applications
Authors: Hafner Christian M. , Manner Hans
Published: July 2010

We propose a new dynamic copula model in which the parameter characterizing dependence follows an autoregressive process. As this model class includes the Gaussian copula with stochastic correlation process, it can be viewed as a generalization of multivariate stochastic volatility models. Despite the complexity of the model, the decoupling of marginals and dependence parameters facilitates estimation. We propose estimation in two steps, where first the parameters of the marginal distributions are estimated, and then those of the copula. Parameters of the latent processes (volatilities and dependence) are estimated using efficient importance sampling. We discuss goodness‐of‐fit tests and ways to forecast the dependence parameter. For two bivariate stock index series, we show that the proposed model outperforms standard competing models. Copyright © 2010 John Wiley & Sons, Ltd.

Die analytische Chemie nutzt vermehrt optoelektronische Techniken mit mikrostrukturierten Komponenten. Nach Chemosensoren beherrschen nun Biosensoren das Feld. Ausschließlich chemisch synthetisierte Rezeptoren bleiben gegenüber molekularbiologischen Reaktionspartnern zurück. In Diagnostik und Lebensmittelkontrolle ist die Zeit autonomer Analysenplattformen angebrochen. Auffällig ist die Dominanz massenspektrometrischer Techniken, sowohl in Kopplung, als auch als Stand‐alone‐Verfahren. Generell geht der Trend in Richtung Life‐Science‐Anwendungen, während die Umweltanalytik fast vollständig verschwindet.

Influence of lee waves on the near‐surface flow downwind of the Pennines
Authors: Sheridan P. F. , Horlacher V. , Rooney G. G. , Hignett P. , Mobbs S. D. , Vosper S. B.
Published: July 2010

The results of a recent field experiment focusing on the near‐surface pressure and flow fields downstream of the Pennines in northern England are presented. The main aim of the experiment is the improvement of wind forecasts downstream of orography. Trapped lee waves commonly occur in westerly flow in this region, and during the experiment there were numerous instances of apparent flow separation, indicating the formation of lee‐wave rotors. The spatial variability of the near‐surface flow in these circumstances is closely linked to the positions of lee‐wave crests and troughs aloft, and appears to be a response to pressure gradients induced by the lee waves. For large‐amplitude waves, it has been possible to demonstrate a correlation between the fractional change of the flow speed across the measurement array (which if large enough may lead to flow separation) and a normalized pressure‐perturbation amplitude.

For a group of lee‐wave cases during which the cross‐mountain flow is strong, a rapid decrease in the Scorer parameter within the lower portion of the troposphere appears to be a prerequisite for rotors to form. However, this does not guarantee their occurrence. For a fixed Scorer‐parameter profile, idealized two‐dimensional simulations indicate that the lee‐wave‐induced pressure‐perturbation amplitude, and hence the occurrence of rotors, is controlled largely by the strength of the wind upstream close to the mountain‐top level. It seems that the combination of a favourable Scorer‐parameter profile and sufficiently strong low‐level winds is required for rotors to develop. © Crown Copyright 2007.

Jacobian mapping between vertical coordinate systems in data assimilation
Authors: Rochon Y. J. , Garand L. , Turner D. S. , Polavarapu S.
Published: July 2010

Radiances measured by remote‐sensing instruments are now the largest component of the atmospheric observation network. The assimilation of radiances from nadir sounders involves fast radiative transfer (RT) models which project profiles provided by forecast models onto the observation space for direct comparison with the measurements. One of the features typically characterizing fast RT models is the use of a fixed vertical coordinate. If the vertical coordinate of the RT model is not identical to that used by the forecast model, an interpolation of forecast profiles to the RT model coordinate is necessary. In variational data assimilation, the mapping of the Jacobians (derivatives of the RT model output with respect to its inputs) from the RT model coordinate to the forecast model coordinate is also required. This mapping of Jacobians is accomplished through the adjoint of the forecast profile interpolator. As shown, the nearest‐neighbour log‐linear interpolator commonly used operationally can lead to incorrect mapping of Jacobians and, consequently, to incorrect assimilation. This incorrect mapping occurs as a result of leaving out intermediate levels in the interpolation. This problem has been previously masked in part through the smoothing effect of forecast‐error vertical correlations on the analysis increments. To solve this problem, two simple versions of an interpolator relying on piecewise log‐linear weighted averaging over the layers are investigated. Both markedly improve Jacobian mappings in the assimilation of observations, with one being slightly favoured over the other. This interpolator is being incorporated into the RTTOV model used by several operational weather forecasting centres. Copyright © 2007 Crown in the right of Canada. Published by John Wiley

The 21–22 January 2004 explosive cyclogenesis over the Aegean Sea: Observations and model analysis
Authors: Lagouvardos K. , Kotroni V. , Defer E.
Published: July 2010

During the period 21–22 January 2004, an explosive cyclogenesis event occurred over the Aegean Sea. The minimum observed pressure was 972 hPa, a value which is among the three lowest observed over the entire Mediterranean Sea during the last 40 years. This paper is devoted to the investigation of the conditions that contributed to the rapid development of this low‐pressure system through analysis of both observations and model results. It was found that the rapid development of the cyclone was associated with a two‐trough system that, under the influence of a very intense upper‐level jet, merged into a single trough and then acquired a negative tilt. Sensitivity tests with the MM5 model showed that the upper‐level dynamic forcing was the main factor that led to the explosive cyclogenesis, while surface sensible and latent heat fluxes contributed to the cyclone deepening mainly during the storm's mature phase.

Evaluation of the use of radiosonde humidity data to predict the occurrence of persistent contrails
Authors: Rädel G. , Shine K. P.
Published: July 2010

Regular visual observations of persistent contrails over Reading, UK, have been used to evaluate radiosonde measurements of temperature and humidity defining cold ice‐supersaturated atmospheric regions which are assumed to be a necessary condition for persistent condensation trails (contrails) to form. Results show a good correlation between observations and predictions using data from Larkhill, 63 km from Reading. A statistical analysis of this result and the forecasts using data from four additional UK radiosonde stations are presented. The horizontal extent of supersaturated layers could be inferred from this to be several hundred kilometres. The necessity of bias corrections to radiosonde humidity measurements is discussed and an analysis of measured ice‐supersaturated atmospheric layers in the troposphere is presented. It is found that ice supersaturation is more likely to occur in winter than in summer, with frequencies of 17.3% and 9.4%, respectively, which is mostly due to the layers being thicker in winter than in summer. The most probable height for them to occur is about 10 km. Copyright © 2007 Royal Meteorological Society

Numerical simulation of a long bora episode is presented and compared with measurements. The goal is to resolve the quasi‐periodic oscillations of the bora gusts, i.e. the pulsations. The model reproduced well the approximately 7 min periodicity of pulsations and the upstream structure of the atmosphere, and can thus be used for the detailed dynamical considerations.

The results of previous studies are confirmed, as well as the hypotheses on the mechanisms responsible for the disappearance of pulsations. Specifically, it is shown that the upper‐tropospheric jet induces strong positive shear throughout the troposphere and consequently the local nonlinearity of the incoming flow weakens. Henceforth, the low‐level wave breaking is diminished and so the pulsations cease. From the three previously proposed generating mechanisms of pulsations, the results obtained point to the Kelvin–Helmholtz instability as the primary mechanism in this case.

Additionally, it seems that the situations with absence of pulsations may be related to the formation of the mountain‐wave‐induced rotor. Copyright © 2007 Royal Meteorological Society
Improving short‐range high‐resolution model precipitation forecast skill using time‐lagged ensembles
Authors: Mittermaier Marion P.
Published: July 2010

High‐resolution forecasts can vary considerably from run to run. Excessive inconsistency is undesirable, especially for the forecaster, who seeks similarities between successive runs to gain confidence in model guidance.

The Met Office 4 km Unified Model runs every 6 h to t + 36 h. Five‐member time‐lag ensembles are created for the most recent 6 h period in order to study the perceived inconsistencies between runs. Mean, maximum, and probability‐of‐precipitation forecast fields are generated, for four different months of operational forecasts chosen to capture different seasonal weather regimes, and compared with the verifying radar accumulation. Each of the individual forecasts (ensemble members) is evaluated and its contribution to the ensemble assessed.

Results show that the time‐lag ensemble performs better at or near the grid scale, and that there is a strong case for recalibration. Indeed, the ensemble approach ensures that the proportion of missed forecast events (which have potentially more serious implication for high‐impact weather) is reduced. In short, the effect of the lagged‐ensemble spread is similar to that of the spread created from perturbed initial conditions in conventional ensembles, improving forecast skill at a higher spatial resolution, thus emulating the requirement for spatial averaging for a single deterministic forecast. Overall, improved forecast skill at longer ranges ensures that time‐lagged ensembles are now a more viable option than in the past. © Crown Copyright 2007.

Assimilation of EOS MLS ozone observations in the Met Office data‐assimilation system
Authors: Jackson D. R.
Published: July 2010

In this paper the impact of Earth Observing System Microwave Limb Sounder (EOS MLS) observations on ozone analyses is investigated using the Met Office data‐assimilation system. EOS MLS was launched in 2004, and produces high‐quality ozone observations in the upper troposphere and stratosphere at high vertical and horizontal resolution. The experiments shown here are run using 3D‐Var and a forecast model that has 50 levels—from the surface to approximately 63 km—and a horizontal resolution of 2.5° latitude by 3.75° longitude. Most of the experiments are run for the period January–February 2005.

The chief impact of assimilating EOS MLS data is a reduction of the mean analysis error, and of the standard deviation, in the lower stratosphere. Compared with control simulations, mean errors drop by 5%–25% in the Southern‐Hemisphere extratropics, by around 10% in the Northern‐Hemisphere extratropics, and by around 50% (with respect to ozonesondes) in the region of the tropical upper troposphere and lower stratosphere.

Further investigation shows that the improved ozone analyses in the Southern Hemisphere largely result from a much better representation of summertime low‐ozone events. These events have been documented in the northern summer stratosphere, but never before in the southern summer stratosphere. In the Northern Hemisphere the addition of EOS MLS to the assimilation system is shown to lead to a better representation of winter polar ozone depletion. At low latitudes, it appears that errors in the background model transport fields often lead to errors in the ozone analysis, but that the addition of high‐density, good‐quality EOS MLS data alleviates much of this error. It is noted that the EOS MLS data have a more beneficial impact on ozone analyses in this region than do data from the Michelson Interferometer for Passive Atmospheric Sounding, which has a similar resolution and observational error to EOS MLS. © Crown Copyright 2007.

Redefining the Future of Perioperative Nursing Education: A Conceptual Framework
Authors: Dumchin Mark
Published: July 2010

Perioperative nursing is practiced in a technologically advanced, fast‐paced environment, and there is a continuing shortage of qualified and competent perioperative nurses. The expansion of nursing education programs into web‐based environments has the potential to address this shortage. Online learning is both effective and efficient and particularly appropriate for adult learners compared with traditional, lecture‐style programs. This article proposes a conceptual framework that combines social constructivism, Benner's Novice to Expert theory, and the principles of adult learning to provide a basis for the design and implementation of future perioperative curricula. Although the proposed framework needs to be questioned and empirically tested through research, the application of this framework could potentially shift the quality of perioperative education to a higher level and result in safer, more highly reliable patient care.
Lean Methodology in Health Care
Authors: Kimsey Diane B.
Published: July 2010

Lean production is a process management philosophy that examines organizational processes from a customer perspective with the goal of limiting the use of resources to those processes that create value for the end customer. Lean manufacturing emphasizes increasing efficiency, decreasing waste, and using methods to decide what matters rather than accepting preexisting practices. A rapid improvement team at Lehigh Valley Health Network, Allentown, Pennsylvania, implemented a plan, do, check, act cycle to determine problems in the central sterile processing department, test solutions, and document improved processes. By using A3 thinking, a consensus building process that graphically depicts the current state, the target state, and the gaps between the two, the team worked to improve efficiency and safety, and to decrease costs. Use of this methodology has increased teamwork, created user‐friendly work areas and processes, changed management styles and expectations, increased staff empowerment and involvement, and streamlined the supply chain within the perioperative area.
Variant anatomy of the uterine artery in a Kenyan population
Authors: Obimbo Moses M. , Ogeng'o Julius A. , Saidi Hassan
Published: July 2010

Objective

To investigate the uterine artery's origin, branching patterns, and relation to the ureter in a Kenyan population.

Method

The uterine arteries of the bodies of 53 girls and women were dissected at the University of Nairobi Department of Human Anatomy to study these patterns. Data were analyzed for frequency and the patterns are presented via digital macrographs.

Results

The uterine artery consistently originated as a branch of the internal iliac artery. It formed the second or third branch of the anterior trunk in 70.8% of cases; it ascended as a single branch, or from a bifurcation, or from a trifurcation in 76.4%, 17.1%, and 6.7% of cases; and lay posterior to the ureter in 3.8% of cases. In all, 46.2% of the uterine arteries studied varied from the classic description.

Conclusion

About half of the uterine arteries had a nonclassic origin, branching pattern, or relation to the ureter—as a posterior relation to the ureter had not been previously described. Surgeons operating in the pelvis should be aware of this variant anatomy to avoid injury to the ureter and other organs.
Qualitative case studies in operations management: Trends, research outcomes, and future research implications
Authors: Barratt Mark , Choi Thomas Y. , Li Mei
Published: July 2010

Our study examines the state of qualitative case studies in operations management. Five main operations management journals are included for their impact on the field. They are in alphabetical order: Decision Sciences, International Journal of Operations and Production Management, Journal of Operations Management, Management Science, and Production and Operations Management. The qualitative case studies chosen were published between 1992 and 2007. With an increasing trend toward using more qualitative case studies, there have been meaningful and significant contributions to the field of operations management, especially in the area of theory building. However, in many of the qualitative case studies we reviewed, sufficient details in research design, data collection, and data analysis were missing. For instance, there are studies that do not offer sampling logic or a description of the analysis through which research out‐comes are drawn. Further, research protocols for doing inductive case studies are much better developed compared to the research protocols for doing deductive case studies. Consequently, there is a lack of consistency in the way the case method has been applied. As qualitative researchers, we offer suggestions on how we can improve on what we have done and elevate the level of rigor and consistency.
Continuum-Activity Index: Managing Admission Inappropriate Stays in a Community Hospital
Authors: Atkinson David I. , Jenkins Sandie , Collins Paul E. , Minor Jane
Published: July 2010

The CONTINUUM-Activity Index was used as a concurrent tool to measure intensity of services delivered in an Acute Care Community Hospital. Applying these specific daily measures identified patients who did not meet admission-appropriateness criteria on the first day of care or did not meet those criteria on two days subsequent to admission. These patients had a high probability that their entire stay would be inappropriate. Action was then taken to move the care process forward, resulting in a significant reduction in inappropriate hospital days.
Communication: Implementation of the Resident Assessment Instrument (RAI): The Benefits of a Structured Communication Plan
Authors: Blair Alison , Brunton Bev , Rook Marilyn
Published: July 2010

Following a government mandate to use the assessment portion of the Resident Assessment Instrument, S&WCHSC began to integrate the RAI into the care of its Aging Program residents. S&WCHSC have used this as an opportunity to provide a structure for assessment and care planning within the existing philosophy of Patient Focused Care. Implementation of the RAI required the development and implementation of a Communication Plan. An adaptation of a framework, “Effective Strategic Planning for Communications” provided guidelines for assessment of key stakeholders' communication needs.

Restructuring the Healthcare Management Paradigm: Toward Organic Management
Authors: Rathwell Thomas , Persaud D. David
Published: July 2010

In the first part of this two part series, we demonstrated that the adoption of production engineering techniques and market-based approaches to the delivery of healthcare have not fulfilled their initial promise. Furthermore, this has placed managers under duress, because they are charged with implementing these mechanisms. In this second article, we propose a new philosophy for managing healthcare organizations that is closer to the roots of healthcare delivery in Canada.

Authors: Chafe Roger , Neville Doreen , Rathwell Thomas , Deber Raisa
Published: July 2010

En raison de leurs effets directs sur l'accès du public aux soins et du fait que les services touchés soient financés par le gouvernement, les décisions en matière de services assurés et d'affectation des ressources représentent un domaine particulièrement important de la participation publique. Nous présentons un cadre qui oriente les décideurs dans des questions clés qu'ils doivent se poser lorsqu'ils décident, structurent, évaluent et diffusent les résultats des exercices de participation du public, notamment en ce qui a trait aux décisions en matière de services assurés et d'affectation des ressources. Le cadre permettra aux décideurs d'obtenir une participation citoyenne viable et significative sur ces sujets.
