Reexamining the relationship between design performance and the design process using reflection in action
Authors: Tang Hsien-Hui , Lee Yuying Y. , Chen Wenzhi 
Published: April 2012

AbstractReflective actions in collaborative design can potentially improve design performance and results. This paper quantitatively reexamines the relationships between reflective activities and design performance during the collaborative design process in terms of reflection in action. Twenty sets of protocol data were encoded by a modified version of Valkenburg and Dorst's coding scheme. Using statistical testing, the relationship between the design performance and the number of activities plus the transitions was examined. A significant statistical correlation was found between the percentage of mature framing (setting up of a desired goal with sufficient follow-ups) and the overall performance. These quantitative results verify the qualitative findings of the previous study.

AbstractIntroduction: When a large-scale disaster occurs, it is necessary to use the available resources in a variety of sites and scenes as efficiently as possible. To conduct such operations efficiently, it is necessary to deploy limited resources to the places where they will be the most effective. In this study, emergency and medical response activities that occurred following the Chuetsuoki Earthquake in Japan were analyzed to assess the most efficient and effective activities.Methods: Records of patient transports by emergency services relating to the Niigata Chuetsuoki Earthquake, a magnitude 6.8 earthquake that struck Japan on 16 July 2007 were analyzed, and interview surveys were conducted.Results: The occurrence of serious injuries caused by this earthquake essentially was limited to the day the earthquake struck. A total of 682 patients were treated on the day of the quake, of which about 90 were hospitalized. Of the 17 patients whose conditions were life-threatening, three were rescued and transported to hospital by firefighters, three were transported by ambulance, and 11 were transported to hospital using private means. Sixteen people were subsequently transferred to other hospitals, six of these by helicopter. There was difficulty in meeting all of the requests for emergency services within 4 to 6 hours of the earthquake’s occurrence. Most transports of patients whose conditions were life-threatening were between hospitals rather than from the scene of the injury. Transfers of critical patients between hospitals were efficient early on, but this does not necessarily mean that inter-hospital transfers were given higher priority than treatment at emergency scenes.Conclusion: During the acute emergency period following a disaster-causing event, it is difficult to meet all requests for emergency services. In such cases, it is necessary to conduct efficient activities that target critically injured patients. Since hospital transfers are matters of great urgency, it is necessary to consider assigning resource investment priority to hospital transfers during this acute period, when ambulance services may be insufficient to meet all needs. To deal with such disasters appropriately, it is necessary to ensure effective information exchange and close collaboration between ambulance services, firefighting organizations, disaster medical assistance teams, and medical institutions.
The Evaluation of Research Methods during Disaster Exercises: Applicability for Improving Disaster Health Management
Authors: Legemaate G.A. Guido , Burkle Frederick M , Bierens Joost J.L.M. 
Published: April 2012

AbstractIntroduction: The objective of this study was to investigate whether disaster exercises can be used as a proxy environment to evaluate potential research instruments designed to study the application of medical care management resources during a disaster.Methods: During an 06 April 2005 Ministerial-level exercise in the Netherlands, three functional areas of patient contact were assessed: (1) Command and Control, through the application of an existing incident management system questionnaire; (2) patient flow and quality of patient distribution, through registration of data from prehospital casualty collection points, ambulances, and participating trauma centers (with inclusion of data in a flow chart); and (3) hospital coping capacity, through timed registration reports from participating trauma centers.Results: The existing incident management system questionnaire used for evaluating Command and Control during a disaster exercise would benefit from minor adaptations and validation that could not be anticipated in the exercise planning stage. Patient flow and the quality of patient distribution could not be studied during the exercise because of inconsistencies among data, and lack of data from various collection points. Coping capacity was better measured by using 10-minute rather than one hour time intervals, but provided little information regarding bottlenecks in surge capacity.Conclusion: Research instruments can be evaluated and improved when tested during a disaster exercise. Lack of data recovery hampers disaster research even in the artificial setting of a national disaster exercise. Providers at every level must be aware that proper data collection is essential to improve the quality of health care during a disaster, and that predisaster cooperation is crucial to validate patient outcomes. These problems must be addressed pre-exercise by stakeholders and decision-makers during planning, education, and training. If not, disaster exercises will not meet their full potential.
Time for Order in Chaos! A Health System Framework for Foreign Medical Teams in Earthquakes
Authors: Lind Karin , Gerdin Martin , Wladis Andreas , Westman Lina , von Schreeb Johan 
Published: April 2012

The number of reported natural disasters is increasing, as is the number of foreign medical teams (FMTs) sent to provide relief. Studies show that FMTs are not coordinated, nor are they adapted to the medical needs of victims. Another key challenge to the response has been the lack of common terminologies, definitions, and frameworks for FMTs following disasters.In this report, a conceptual health system framework that captures two essential components of health care response by FMTs after earthquakes is presented. This framework was developed using expert panels and personal experience, as well as an exhaustive literature review.The framework can facilitate decisions for deployment of FMTs, as well as facilitate coordination in disaster-affected countries. It also can be an important tool for registering agencies that send FMTs to sudden onset disasters, and ultimately for improving disaster response.

AbstractIntroduction: The Working Group (WG) on Mental Health and Psychosocial Support participated in its second Humanitarian Action Summit in 2011. This year, the WG chose to focus on a new goal: reviewing practice related to transitioning mental health and psychosocial support programs from the emergency phase to long-term development. The Working Group's findings draw on a review of relevant literature as well as case examples.Objectives: The objective of the Working Group was to identify factors that promote or hinder the long term sustainability of emergency mental health and psychosocial interventions in crisis and conflict, and to provide recommendations for transitioning such programs from relief to development.Methods: The Working Group (WG) conducted a review of relevant literature and collected case examples based on experiences and observations of working group members in implementing mental and psychosocial programming in the field. The WG focused on reviewing literature on mental health and psychosocial programs and interventions that were established in conflict, disaster, protracted crisis settings, or transition from acute phase to development phase. The WG utilized case examples from programs in Lebanon, the Gaza Strip, Sierra Leone, Aceh (Indonesia), Sri Lanka, and New Orleans (United States).Results: The WG identified five key thematic areas that should be addressed in order to successfully transition lasting and effective mental health and psychosocial programs from emergency settings to the development phase. The five areas identified were as follows: Government and Policy, Human Resources and Training, Programming and Services, Research and Monitoring, and Finance.Conclusions: The group identified several recommendations for each thematic area, which were generated from key lessons learned by working group members through implementing mental health and psychosocial support programs in a variety of settings, some successfully sustained and some that were not.
Prehospital Analgesia in New South Wales, Australia

Published: April 2012

AbstractIntroduction:With at least 20% of ambulance patients reporting pain of moderate to severe intensity, pain management has become a primary function of modern ambulance services. The objective of this study was to describe the use of intravenous morphine, inhaled methoxyflurane, and intranasal fentanyl when administered in the out-of-hospital setting by paramedics within a large Australian ambulance service.Methods:A retrospective analysis was conducted using data from ambulance patient health care records (PHCR) for all cases from 01 July 2007 through 30 June 2008 in which an analgesic agent was administered (alone or in combination).Results:During the study period, there were 97,705 patients ≤100 years of age who received intravenous (IV) morphine, intranasal (IN) fentanyl, or inhaled methoxyflurane, either alone or in combination. Single-agent analgesia was administered in 87% of cases. Methoxyflurane was the most common agent, being administered in almost 60% of cases. Females were less likely to receive an opiate compared to males (RR = 0.83, 95% CI, 0.82–0.84,p<0.0001). Pediatric patients were less likely to receive opiate analgesia compared to adults (RR = 0.65, 95% CI, 0.63–0.67,p<0.0001). The odds of opiate analgesia (compared to pediatric patients 0–15 years) were 1.47; 2.10; 2.56 for 16–39 years, 40–59 years, and ≥60 years, respectively. Pediatric patients were more likely to receive fentanyl than morphine (RR = 1.69, 95% CI, 1.64–1.74,p< 0.0001).Conclusion:In this ambulance service, analgesia most often is provided through the use of a single agent. The majority of patients receive non-opioid analgesia with methoxyflurane, most likely because all levels of paramedics are authorized to administer that analgesic. Females and children are less likely to receive opiate-based analgesia than their male and adult counterparts, respectively. Paramedics appear to favor intranasal opiate delivery over intravenous delivery in children with acute pain.

Published: April 2012

AbstractIntroduction: Post-traumatic stress disorder (PTSD) is a common condition among Japanese firefighters. The purpose of this study was to clarify the relationship of PTSD scores to job stress, social support, and depressive stress among Japanese firefighters.Methods: A total of 1,667 Japanese firefighters working for the local government completed a questionnaire that was used to gather information pertaining to age, gender, job type, job class, marital status, and smoking and drinking habits. Questionnaires from the Center for Epidemiologic Studies Depression Scale (CES-D), the Japanese version of the U.S. National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire, and the IES-R were also used.Results: After adjustment for age and gender, subjects in the PTSD-positive group had significantly higher scores for inter-group conflict, role ambiguity, and CES-D, as well as significantly lower scores for social support from their supervisors compared to those in the PTSD-negative group.Conclusions: High inter-group conflict and role ambiguity, as well as low social support from supervisors and the presence of depressive symptoms, may influence the development of PTSD among Japanese firefighters.
The Power of the Unexpected
Authors: Warner Brian 
Published: April 2012

AbstractThe history of astronomy has provided variable sources of unexpected kinds—from novae recorded in oriental archives, rapid radio, optical and high-energy changes in white dwarfs, neutron star and black hole binaries, to recent discoveries with satellites. A brief overview is given, as a prelude to a conference that anticipates a tidal wave of observations and discoveries to be made at all wavelengths during the next five to ten years.
Light Echoes of Transients and Variables
Authors: Rest Armin 
Published: April 2012

SummaryTycho Brahe's observations of a supernova in 1572 challenged the contemporaneous European view of the cosmos that the celestial realm was unchanging. 439 years later we have once again seen the light that Tycho saw, as some of the light from the 1572 supernova is reflected off dust and is only now reaching Earth. These light echoes, as well as ones detected from other transients and variables, give us a very rare opportunity in astronomy: direct observation of the cause (the supernova explosion) and the effect (the supernova remnant) of the same astronomical event. Furthermore, in some cases we can compare light echoes at different angles around a supernova remnant, and thus investigate possible asymmetry in the supernova explosion. In addition, in cases where the scattering dust is favorably positioned, the geometric distance to the SN remnant can be determined using polarization measurements. These techniques have been successfully applied to various transients in the last decade, and the talk gave an overview of the scientific results and techniques, with a particular focus on the challenges we will face in the current and upcoming wide-field time-domain surveys.

AbstractThe Fermi Gamma-ray Space Telescope, as an all-sky survey and monitoring mission, is producing well-sampled gamma-ray light curves for dozens of blazars and other high-energy sources. We report highlights of gamma-ray variability properties, and outline multi-frequency observing campaigns that are targeted to new or known blazars which emit gamma rays.
Two Centuries of Observing R Coronæ Borealis
Authors: Clayton Geoffrey C. 
Published: April 2012

AbstractR Coronæ Borealis was found to be variable in the year 1783, and was one of the first variable stars to be so identified. Its class, the R Coronæ Borealis (RCB) stars, are rare hydrogen-deficient carbon-rich supergiants. RCB stars undergo massive declines of up to 8 mag due to the formation of carbon dust at irregular intervals. The mechanism of dust formation around RCB stars is not well understood, but the dust is thought to form in or near the atmosphere of the star. Their rarity may stem from the fact that they are in an extremely rapid phase of the evolution, or are in an evolutionary phase that most stars do not undergo. Several evolutionary models have been suggested to account for the RCB stars, including a merger of two white dwarfs (WDs) or a final helium-shell flash (FF) in a PN central star. The large overabundance of 18O found in most of the RCB stars favours the WD merger model, while the presence of Li in the atmospheres of five RCB stars favours the FF one. In particular, the measured isotopic abundances imply that many, if not most, RCB stars are produced by WD mergers, which may be the low-mass counterparts of the more massive mergers thought to produce type Ia supernovæ. Understanding these enigmatic stars depends to a large extent on continuous monitoring to catch their irregular but rapid variations caused by dust formation, their variations due to stellar pulsations, and long-term changes that may occur over centuries. I will use observations of R Coronæ Borealis obtained over 200 years to demonstrate what kinds of monitoring are necessary for these and similar classes of variables.
Probing Magnetic Mysteries with Stellar Flares
Authors: Osten Rachel A. 
Published: April 2012

AbstractFlares are a fact of life for stars in the cool half of the H-R diagram. The production of magnetic fields and the consequent dynamic interactions of field and plasma give rise to observational phenomena which span the electromagnetic spectrum. Stellar flares have an impact not only on the stellar atmosphere but also the stellar environment, which can include forming and already formed planets. This talk gave a brief review of our current state of understanding of stellar flares, highlighting some of the main unanswered questions by a panchromatic approach. It also emphasized commonalities between observations and analysis of stellar flares and other types of transient and variable sources.
The CoRoT and Kepler Revolution in Stellar Variability Studies
Authors: Degroote Pieter , Debosscher Jonas 
Published: April 2012

AbstractSpace-based observations of variable stars have revolutionized the field of variability studies. Dedicated satellites such as the CoRoT and Kepler missions have duty cycles which are unachievable from the ground, and effectively solve many of the aliasing problems prevalent in ground-based observation campaigns. Moreover, the location above the Earth's atmosphere eliminates a major source of scatter prevalent in observations from the ground. These two major improvements in instrumentation have triggered significant increases in our knowledge of the stars, but in order to reap the full benefits they are also obliging the community to adopt more efficient techniques for handling, analysing and interpreting the vast amounts of new, high-precision data in an effective yet comprehensive manner. This workshop heard an outline of the history and development of asteroseismology, and descriptions of the two space missions (CoRoT and Kepler) which have been foremost in accelerating those recent developments. Informal discussions on numerous points peppered the proceedings, and involved the whole audience at times. The conclusions which the workshop reached have been distilled into a list of seven recommendations (Section 5) for the asteroseismology community to study and absorb. In fact, while addressing activities (such as stellar classification or analysing and modelling light curves) that could be regarded as specific to the community in question, the recommendations include advice on matters such as improving communication, incorporating trans-disciplinary knowledge and involving the non-scientific public that are broad enough to serve as guidelines for the astrophysical community at large.
Binarity and Stellar Evolution
Authors: Griffin R. E. M. , Rucinski Slavek 
Published: April 2012

AbstractModels of stellar evolution constitute an extremely powerful, and for the most part apparently very successful, tool for understanding the progression of a star through its lifetime as a fairly compact entity of incandescent gas. That success has led to stellar evolution theory becoming a crutch when an observer is faced with objects whose provenance or current state are in some way puzzling, but how safe a crutch? The validity of the theory is best checked by examining binary systems whose component parameters have been determined with high precision, but it can be (and needs to be) honed through the many challenges which non-conformist single stars and triple systems also present. Unfortunately the lever of observational parameters to constrain or challenge stellar evolution theory is not as powerful as it could be, because not all determinations of stellar parameters for the same systems agree to within the precisions claimed by their respective authors. What are the sources of bias—the data, the instrument or the techniques? The workshop was invited to discuss particularly challenging cases, and to attempt to identify how and where progress might be pursued.
Workshop on Extreme Physics
Authors: Mundell Carole , Sullivan Mark 
Published: April 2012

SummaryNever before has there been such a wealth of versatile ground- and space-based facilities with which to detect variable emission across the electromagnetic spectrum and beyond, to non-EM signals such as neutrinos and gravitational waves, to probe the most extreme phenomena in the Universe. The variable sky is already providing a wealth of new and surprising observations of phenomena such as GRBs, SNe and AGN that are pushing current theories beyond the state of the art. Multi-messenger follow-up will soon become de rigeur, and upcoming radio and optical all-sky transient surveys will revolutionise the study of the transient Universe. In addition to the technical and data challenges presented by such surveys, a major new challenge will be the interpretation of the wealth of available data and the identification of the underlying physics of new classes of variable (and potentially exotic) objects. Theoretical predictions will be vital for interpreting these future transient discoveries.The goal of this workshop was to bring together theorists and observers in order to identify unexplored synergies across three main research areas of extreme physics: gamma-ray bursts, supernovæ and, more generically, relativistic jets. It aimed to discuss key outstanding questions in these rapidly moving fields, such as the composition and acceleration of GRB and AGN jets, GRB progenitors and central engines, the origin of the wide range of observed variability time-scales in GRB prompt and after-glow light curves and related cosmological applications, the physics of the newly-discovered ultra-luminous SN-like optical transients—as well as to speculate on what we might hope to discover with future technology.The workshop absorbed two 90-minute sessions, selecting 3 main science topics (Relativistic Jets, GRBs and SNe) which it organised as structured discussions driven by a series of short but provocative questions. The final session featured a panel-led debate but with full audience participation.
Cepheids in Galactic Open Clusters: An All-sky Census
Authors: Anderson Richard I. , Eyer Laurent , Mowlavi Nami 
Published: April 2012

AbstractWe perform an all-sky search for classical (type I) Cepheids that are members of Galactic Open Clusters. Our approach is multi-dimensional, using all available spatial and kinematic parameters. The quantification of errors is crucial for this analysis, so care is taken to find adequate and realistic representations of parameter uncertainties. The data employed in the calculation are taken from published catalogues and the literature, supplemented by specific radial-velocity observations. Our work in progress is outlined here, and issues related to the inhomogeneity of cluster radii in the literature are discussed in some detail.
