  2. PREDICT : A CASE STUDY.

    Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

  3. Termination: A Case Study.

    PubMed

    Friedberg, Ahron L

    2015-12-01

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    Caring for J.D. was a stressful experience. The extent of her wounds, pain, and limited options for treatment was very frustrating for the nursing staff. Although she did not survive, patient outcomes were met to some degree. Her pain was controlled to a greater extent, and there was less infection present in her wounds. The nurses worked with J.D. closely to improve her pain control and facilitate less painful dressing changes. They were vigilant in assessing the progress of her wound healing and communicating any increased signs of infections from her wounds. They sang with her to help distract her from the pain she was experiencing and to help her cope with her lengthy 8-month hospitalization. Providing care for J.D. was also a very important learning experience for nurses in terms of appropriate pain management for patients with CUA, wound care, and the need to sustain adequate nutrition to promote wound healing. CUA is a rare but potentially fatal disease that occurs in patients with end stage renal disease (ESRD). Early diagnosis and treatment are essential to prevent the devastating effects of this disease. Nephrology nurses need to reinforce the importance of keeping calcium, phosphorous, and parathyroid levels within normal ranges for their patients on dialysis. They also need to be vigilant in monitoring for potential CUA skin lesions to prevent and treat it early. To date, treatment options are mostly based on findings from case reports. Treatment requires a multidisciplinary approach with input from nephrologists, nurses, pain specialists, infectious disease specialists, and surgeons. The major goals of treatment are controlling risk factors, controlling pain, and preventing wound infection and possible sepsis. More studies need to be conducted to test interventions that may help treat CUA. PMID:23094342

    2007-09-01

    Quantifying the results for a multi-conjugate adaptive optics (MCAO) system is more complex than a traditional adaptive optics (AO) system. The complexity of analyzing a MCAO system stems from using multiple deformable mirrors (DMs) and quantifying the influence functions at the wavefront sensor (WFS). In this paper, analysis tools are developed to quantify MCAO performance. Influence functions from two deformable mirrors are propagated to a WFS using CODEV to simulate an MCAO design comparable to the Dunn Solar Telescope (DST). Using MATLAB, the propagated influence functions are mapped to the appropriate field positions, and reconstructor matrices are built using the mapped influence functions. Next, a correctability analysis was performed using theoretical random phase screens. The developed tools are versatile and useful as a system design tool and in a laboratory setting.

  10. Allographic agraphia: A case study

    PubMed Central

    Menichelli, Alina; Rapp, Brenda; Semenza, Carlo

    2011-01-01

    We report the case of patient MN, diagnosed with frontotemporal dementia, who exhibited a severe impairment in writing letters and words in upper-case print in the face of accurate production of the same stimuli in lower-case cursive. In contrast to her written production difficulties, MN was unimpaired in recognizing visually presented letters and words in upper-case print. We find a modest benefit of visual form cueing in the written production of upper-case letters, despite an inability to describe or report visual features of letters in any case or font. This case increases our understanding of the allographic level of letter-shape representation in written language production. It provides strong support for previous reports indicating the neural independence of different types of case and font-specific letter-shape information; it provides evidence that letter-shape production does not require explicit access to information about the visual attributes of letter shapes and, finally, it reveals the possibility of interaction between processes involved in letter-shape production and perception.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

  12. A case for case studies: exploring the use of case study design in community nursing research.

    PubMed

    Bergen, A; While, A

    2000-04-01

    The case study has become an accepted vehicle for conducting research in a variety of disciplines. However, the meaning behind the term is not always made explicit by researchers and this has given rise to a number of assumptions which are open to challenge, and to questions about the robustness of the method. This paper explores some of the issues arising from one particular definition of case study research, used in a study by Yin which examined the practice of case management in community nursing. Four main areas are discussed. First, defining 'case' is seen to pose questions about the relationship of the phenomenon to its context, the degree of researcher control over case definition, the limits to what may constitute a 'case' and what is meant by the term 'unit of analysis'. Second, the relevance of external validity to case study research is supported through the use of a number of tactics, in particular Yin's concept of replication logic, which involves generalizing to theory, rather than to empirical data. Third, the use of method triangulation (multiple methods of data collection) is advanced as a means of enhancing construct validity in research where data converge around a particular theory. Finally, the relationship of the case study to theory construction, through the prior development of 'propositions' is discussed. Each of these issues is applied to the design and conduct of a research study based closely on Yin's multiple case study framework. Thirteen 'cases' were selected of case management practice and data were collected through interviews and examination of literature and documentation, to explore the suitability of community nurses for the role. It is concluded that, given the appropriate subject matter, context and research aims, the case study method may be seen as a credible option in nursing research. PMID:10759989

  13. A case study of embarrassment.

    PubMed

    Dann, O T

    1977-01-01

    The psychoanalytic references to embarrassment are reviewed. Embarrassment, in the literature, is seen largely as an affect involving exhibitionistic and scopophilic conflicts and defenses against these. A case in which embarrassment was prominent is discussed. Embarrassment in the patient was an ego response which implied an external object for its manifestation. It involved exhibitionistic and scopophilic conflicts and projective defenses, but also operated in ego-gratifying and adaptive ways. Her embarrassment was understood through the analysis of an initial embarrassing dream of nakedness and other dreams and associated material as the defensive out-grouth of repeated exposures to the primal scene. Embarrassment was a resistance to remembering in the analysis, and the primal-scene experiences were partially reconstructed. The analytic situation was, in many ways, a symbolic re-creation of the primal scene, including the patient's response of embarrassment. The development of embarrassment in the patient's childhood was furthered and confirmed by its being an identification with the attitudes of both parents. Finally, some reflections on embarrassment and shame in its various forms are set forth. PMID:560404

    Outage management issues identified from a field study conducted at a two-unit commercial pressurized water reactor (PWR), when one unit was in a refueling outage and the other unit was at full power operation, are the focus of this paper. The study was conduced as part of the US Nuclear Regulatory Commission's (NRC) organizational factors research program, and therefore the issues to be addressed are from an organizational perspective. Topics discussed refer to areas identified by the NRC as critical for safety during shutdown operations, including outage planning and control, personnel stress, and improvements in training and procedures. Specifically, issues in communication, management attention, involvement and oversight, administrative processes, organizational culture, and human resources relevant to each of the areas are highlighted by example from field data collection. Insights regarding future guidance in these areas are presented based upon additional data collection subsequent to the original study.

    1982-09-01

    A small change in brick dimensions resulted in an increase in the perceived work-load of men loading and unloading pallets of bricks by hand. A laboratory study indicated that the change in brick dimensions required changes in grip pattern in order to unload bricks at the same rate, moving the same number at a time. These changed grip patterns resulted in increased upper body movement, increased chest-muscle activity and higher heart rates. These differences were reflected in higher subjective ratings of fatigue. PMID:15676442

    This paper details the implementation experience of a work redesign process in a neurosurgical setting in a large community hospital, from conception to "live" demonstration. First, the concept of work redesign is explored, in relation to its underpinnings and its application in the health care setting. Work redesign has two elements: first, it involves the reconfiguration in the job or work role itself and second, a change in the way work is actually performed. Next, the model as it was conceived by the organization, is described. While the "high level" or organizational-wide design was constructed by a central steering team, we recognized the need to customize the model to the unique needs of each clinical service area. Finally, implementation is discussed, including structure, process, evaluation and critical success factors. PMID:9295482

    Optic aphasia is a rare syndrome in which patients are unable to name visually presented objects but have no difficulty in naming those objects on tactile or verbal presentation. We report a 79-year-old man who exhibited anomic aphasia after a left posterior cerebral artery territory infarction. His naming ability was intact on tactile and verbal semantic presentation. The results of the systematic assessment of visual processing of objects and letters indicated that he had optic aphasia with mixed features of visual associative agnosia. Interestingly, although he had difficulty reading Hanja (an ideogram), he could point to Hanja letters on verbal description of their meaning, suggesting that the processes of recognizing objects and Hanja share a common mechanism.

    Pheasant Project was the name given to a consortium of oil companies that drilled 49 dry holes across central Saskatchewan during late 1968 and early 1969. It was hoped to find commercial amounts of hydrocarbons within reefs of the Middle Devonian Winnipegosis Formation and thus establish central Saskatchewan as a new oil province. Unfortunately, the dry holes discouraged further exploration for deep oil both in the southeast and in the central parts of the province until recent Winnipegosis oil discoveries were made in the tableland area. Why was the Pheasant Project such a disaster. The Pheasant Project was a master-pooling of individual exploration permits held by a variety of companies and arranged by an enterprising landman. The Saskatchewan government agreed to the master-pooling on the condition that the wells be drilled quickly and efficiently. Finding oil became secondary to satisfying the pooling terms. All wells were located within the central part of the Elk point seaway, with the dominant exploration concept being the Keg River-Rainbow Lake model. Contrary to popular belief, the Pheasant Project did find shows of oil, as well as favorable reservoirs. Careful examination of the Pheasant wells reveals fundamental sedimentological sequences and patterns of salt-solution tectonics that are critical to defining oil plays in the Elk Point sequence. Distribution of reservoirs within Winnipegosis reefs, reef morphology, the nature of the Shell Lake-Quill unit, and source rock factors are a few of these.

    Levine, L.O.

    1992-09-01

    This paper describes how pull production methods have been applied to a manual transmission remanufacturing line at Tooele Army Depot in Utah. The paper emphasizes techniques for linking the control of disassembly and cleaning operations to the repair and assembly portions of the production system (PP C). The primary objective is to show that production planning and control can be simplified when pull mechanisms are combined with shop floor improvements. One approach to applying MRP II to remanufacturing is to use a separate production schedule for the disassembly and assembly portions of the operation. This approach is primarily needed when managing the delivery and inventory of cores is critical to the successful operation of a remanufacturing organization. Because Army depots frequently have an adequate inventory of cores on hand (somewhere on-site), this requirement is usually less significant. Therefore, it is possible to eliminate the use of a master production schedule for disassembly and rely on pull linkages from the repair and assembly operations to control the activity of the disassembly and cleaning operations. In remanufacturing environments having multiple products and adequate buffers of core inventory, effective coordination of disassembly and cleaning functions with assembly production requirements becomes a key production control issue.

    Domingos, P.

    1996-12-31

    Two of the most popular approaches to induction are instance-based learning (IBL) and rule generation. Their strengths and weaknesses are largely complementary. IBL methods are able to identify small details in the instance space, but have trouble with attributes that are relevant in some parts of the space but not others. Conversely, rule induction methods may overlook small exception regions, but are able to select different attributes in different parts of the instance space. The two methods have been unified in the RISE algorithm. RISE views instances as maximally specific rules, forms more general rules by gradually clustering instances of the same class, and classifies a test example by letting the nearest rule win. This approach potentially combines the advantages of rule induction and IBL, and has indeed been observed to be more accurate than each on a large number of bench-mark datasets. However, it is important to determine if this performance is indeed due to the hypothesized advantages, and to define the situations in which RISE`s bias will and will not be preferable to those of the individual approaches. This abstract reports experiments to this end in artificial domains.

    Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors. PMID:18028537

    Over the last few decades much research has been done into the raised level of psychiatric comorbidity in epilepsy. On the basis of a case study of a patient suffering from post-ictal psychoses we explain the psychiatric differential diagnosis within the framework of epilepsy and we investigate the frequent psychiatric side-effects of anticonvulsants. It is concluded that the links between epilepsy and psychiatric symptoms are complex and that the neuropsychiatry of epilepsy is concerned with syndromes that are unique and do notfit into modern psychiatric classification systems.

    This descriptive case study illustrates the experiences of a 55-year-old male with a chronic disability resulting from a stroke, living in the community and a clinician's trial using occupation-based interventions predominately in a rehabilitation setting. The participant engaged in occupation-based interventions three times a week for 5 weeks guided by the Canadian Occupational Performance Measure (COPM). Data were collected through semi-structured interviews during the intervention sessions and journal entries made by the therapist. Results suggested occupation-based interventions facilitated a transformation for both the client and the therapist by enhancing the participant's occupational performance and the ability to resume previous roles. The therapist's belief in the power and value of occupation-based practice was reinforced and validated, particularly in the rehabilitation of an individual with chronic stroke. PMID:24867352

    The research was conducted to two parts. Part one consisted of a study of the feasibility of running the Space Transportation Model simulation on an office IBM-AT. The second part was to design simulation runs so as to study the effects of certain performance factors on the execution of the simulation model. The results of this research are given in the two reports which follow: Microcomputer vs. Mainframe Simulation: A Case Study and Fractional Factorial Designs of Simulation Runs for the Space Transportation System Operations Model. In the first part, a DOS batch job was written in order to simplify the execution of the simulation model on an office microcomputer. A comparison study was then performed of running the model on NASA-Langley's mainframe computer vs. running on the IBM-AT microcomputer. This was done in order to find the advantages and disadvantages of running the model on each machine with the objective of determining if running of the office PC was practical. The study concluded that it was. The large number of performance parameters in the Space Transportation model precluded running a full factorial design needed to determine the most significant design factors. The second report gives several suggested fractional factorial designs which require far fewer simulation runs in order to determine which factors have significant influence on results.

    This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years; 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered. PMID:25000372

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    1994-01-01

    Many acceleration-sensitive, microgravity science experiments will require active vibration isolation from manned orbiters on which they will be mounted. The isolation problem, especially in the case of a tethered payload, is a complex three-dimensional one that is best suited to modern-control design methods. In this paper, extended H(sub 2) synthesis is used to design an active isolator (i.e., controller) for a realistic single-input-multiple-output (SIMO) microgravity vibration isolation problem. Complex mu-analysis methods are used to analyze the isolation system with respect to sensor, actuator, and umbilical uncertainties. The paper fully discusses the design process employed and the insights gained. This design case study provides a practical approach for isolation problems of greater complexity. Issues addressed include a physically intuitive state-space description of the system, disturbance and noise filters, filters for frequency weighting, and uncertainty models. The controlled system satisfies all the performance specifications and is robust with respect to model uncertainties.

    PubMed

    Worsfold, Denise

    2006-09-01

    The purpose of this case study was to find out how easy it was to access information on the hygiene standards of eating places open to the public. Using the Freedom of Information (FOI) Act 2000, four adjacent local authorities in South Wales were asked to provide the last food hygiene report of an eating place in their area. The disclosed reports were assessed to determine how useful they would be to an individual seeking more information on a food premise. It was relatively easy to obtain information from two authorities and difficult if not impossible with the others. One local authority refused to release information despite the intervention of the FOI Commissioner. The quality of the information released was variable. This ranged from a completed comprehensive inspection protocol to a hand-written, illegible, incomplete report that failed to adequately differentiate between requirements and recommendations. Without some training in food law and food hygiene it would be difficult to interpret the reports. There was no evidence from the information provided of inspection scoring. The case study raises concerns about the effectiveness of the Act for consumers who wish to obtain information about the hygiene standards of food premises. While the specialist information provided by hygiene inspection reports may be useful to businesses it is not helpful for the lay public. Consumers must be prepared to exercise patience and tenacity if they want this information. Concerns must be raised about the consistency of the inspection process and about the willingness of some local authorities to be transparent about the inspection and enforcement process.

    Although astronomy plays an important role in the most various outreach initiatives, as well as school science curricula, due to its strong visual component in knowledge acquisition, astronomy subjects are not entirely well addressed and accessed by visually impaired students and/or general public. This stresses the need of more tactile material production, still very scarce in an educational context whether formal or informal. This is a case study activity developed based on different schematic tactile images of several objects present in our solar system. These images in relief, highlight, through touch, several relevant features present in the different astronomical objects studied. The scientific knowledge is apprehended through the use of a tactile key, complemented with additional information. Through proper hands-on activities implementation and careful analysis of the outcome, the adapted images associated with an explanatory key prove to be a valuable resource in tactile astronomy domain. Here we describe the process of implementing such initiative near visually impaired students. The struggles and challenges perceived by all involved and the enrichment experience of engaging astronomy with visually impaired audiences, broadening horizons in an overall experience accessible to all.

    PubMed

    Gendle, Mathew H

    2007-01-01

    A case study of a rare form of synesthesia is presented, where specific words act as the inducer, and gustatory sensations function as the concurrent. The female participant (TD) was twice presented with a list of 806 English words and 222 grammatically correct non-words (with 3 months between presentations). For each presentation, TD was asked to provide: a subjective description of the gustatory experience (if any) associated with each stimulus; a rating (from 0 to 10) of the intensity of the gustatory experience; and an indication (yes/no) if the experience was aversive. TD's responses across the two presentations were quantified, and comparisons are provided. In addition, TD's ability to create and recall novel word-taste associations was compared to that demonstrated by a sample of ten age-matched non-synesthete females. TD's synesthetic experiences were found to be highly consistent, more common in English words than non-words, and rarely aversive. Although TD was superior to control participants in remembering novel word-taste associations, her reported experiences cannot be wholly explained by either an exceptional non-synesthetic learning of taste-word associations over time, or a clear response to phonemes, rather than whole words. These conclusions are compared to the five other published reports of word-gustatory synesthesia, and directions for future research are discussed. PMID:17564196

  9. Quantifying Wetland Functions: A Case Study

    Wetlands are reputed to reduce peak flows and improve water quality by trapping sediment and phosphorus. However, there are relatively few studies that quantify these wetland functions. This paper reports on a study of a 45-hectare wetland in southern Wisconsin. The wetland is traversed by a stream channel that drains a predominantly agricultural 17.4 km2 watershed. During the spring and summer of 2006, we collected stage data and water samples at stations upstream and downstream of the wetland, with the former accounting for 82% of the contributing area. Continuous measurements of water stage at these stations were used to construct a streamflow record. During storm events water samples were taken automatically at 2-hour intervals for the first 12 samples and 8-hour intervals for the next 12 samples. Samples were analyzed for total suspended solids, total phosphorus, and dissolved reactive phosphorus. Ten events were observed during the observation period; the two largest events were 1 to 2-year storms. One-dimensional unsteady flow routing was used to estimate the maximum extent of wetland inundation for each event. When normalized for flow volume, all peak flows were attenuated by the wetland, with the maximum attenuation corresponding to the intermediate events. The reduced attenuation of the larger events appears to be due to filling of storage, either due to antecedent conditions or the event itself. In the case of sediment, the amount leaving the wetland in the two largest storms, which accounted for 96% of the exported sediment during the period of observation, was twice the amount entering the wetland. The failure of the wetland to trap sediment is apparently due to the role of drainage ditches, which trap sediment during the wetland-filling phase and release it during drainage. The export of sediment during the largest events appears to result from remobilization of sediment deposited in the low-gradient stream channel during smaller events. This

The task analyzed is a successful example of the use of rapid prototyping as applied to command and control for the U.S. Air Force and provides the U.S. Air Force Military Airlift Command with the ability to track aircraft, air crews and payloads worldwide. The task consists of a replicated database at several globally distributed sites. The local databases at each site can be updated within seconds after changes are entered at any one site. The system must be able to handle up to 400,000 activities per day. There are currently seven sites, each with a local area network of computers and a variety of user displays; the local area networks are tied together into a single wide area network. Using data obtained for eight modules, totaling approximately 500,000 source lines of code, researchers analyze the differences in productivities between subtasks. Factors considered are percentage of Ada used in coding, years of programmer experience, and the use of Ada tools and modern programming practices. The principle findings are the following. Productivity is very sensitive to programmer experience. The use of Ada software tools and the use of modern programming practices are important; without such use Ada is just a large complex language which can cause productivity to decrease. The impact of Ada on development effort phases is consistent with earlier reports at the project level but not at the module level.

    To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard ("It Could Happen to You") on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner's musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded) interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener's statements more than their partner's argues against a simple notion that performers' interpretations are always privileged relative to an outsider's.

    Software reuse has several obvious advantages. By taking advantage of the experience and skill of colleagues one not only saves time, money and resources, but can also jump start a project that might otherwise have floundered from the start, or not even have been possible. One of the least talked about advantages of software reuse is it helps keep the work interesting for the developers. Reuse prevents developers from spending time and energy writing software solutions to problems that have already been solved, and frees them to concentrate on solving new problems, developing new components, and doing things that have never been done before. At the National Snow and Ice Data Center we are fortunate our user community has some unique needs that aren't met by mainstream solutions. Consequently we look for reuse opportunities wherever possible so we can focus on the tasks that add value for our user community. This poster offers a case study of one thread through a decade of reuse at NSIDC that has involved eight different development efforts to date.

    2005-01-01

    Background Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. Methods We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). Results The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). Conclusion This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs. PMID:15882451

  2. A case study of preferential bestiality.

    Earls, Christopher M; Lalumière, Martin L

    2009-08-01

    In a previous article, we presented phallometric data to illustrate a case of preferential bestiality or zoophilia (Earls & Lalumière, Sex Abuse: J Res Treat, 14:83-88, 2002). Based on the available literature, we argued that a marked preference for having sex with animals over sex with humans is extremely rare. In the present article, we describe a second case of zoophilia that challenges the widely held assumptions that men who have sex with animals are generally of below average intelligence and come from rural areas. In addition, we provide a brief review of a burgeoning quantitative literature using large groups of zoophiles recruited from internet sources. Although estimates of the prevalence of zoophilia are not possible at this time, it appears that zoophilia is not as rare as once thought and shares many features with other atypical sexual interests.

    Humans show a wide array of sexual preferences and behaviors. Although most humans prefer and have sex with consenting adults of the opposite sex, some individuals have unconventional preferences with regard to the sex or age of sexual partners, or with regard to the nature of sexual activities. In this paper, we describe a rare case of preferential bestiality, or zoophilia. The client meets the most stringent criteria for the diagnosis of zoophilia. In particular, his phallometrically measured arousal pattern shows a sexual preference for horses over other species, including humans. PMID:11803597

    Anejaculation is an uncommon clinical entity that may result from a variety of causes, both organic and psychological. Psychogenic anejaculation is influenced by relationship, behavioral, and psychological factors. We present a clinical case of situational anejaculation, which was managed with a combination of techniques that addressed these factors including changes in masturbatory technique, improved marital communication and quality, and reduction of anxiety using cognitive behavioral techniques. It is suggested that the standard techniques of sex therapy be modified and tailored to manage the specific problems of the individual patient. PMID:25035564

    1989-10-01

    This paper gives details of a recent court case conducted in Australia concerning a compensation claim made by a radar technician for subcapsular posterior cataracts allegedly caused by exposure to microwave radiation. A discussion of some relevant material, including the likely invalidation of certain in vivo ocular exposures due to the use of a metallic cannula and the relevance of in vitro exposures of rat lenses, are presented. The key findings of the court are also summarized. The ruling of the court was that it was probable that the level of microwave exposure did not cause, or accelerate the development of, the cataracts or contribute to doing so. Consequently, the claim was dismissed. PMID:2529231

    2009-02-01

    Cornelia de Lange syndrome (CDLS) is a relatively common multiple congenital anomaly/mental retardation disorder with an unknown genetic and molecular pathogenesis. The essential features of this developmental malformation syndrome are retardation in growth, developmental delay, various structural limb abnormalities, and distinctive facial features. Most cases are sporadic and are thought to result from a new dominant mutation. Consequently, hypotheses regarding the pathogenetic mechanisms underlying the two distinct phenotypes, classic and mild, are purely speculative. The recent discovery of molecular techniques and identification of the NIPBL gene has allowed etiologic diagnosis of this disorder. In this article, we describe a patient with CDLS in whom conventional cytogenetics, fluorescence in situ hybridization, and NIPBL gene mutation analysis determined an etiologic diagnosis, providing precise genetic counseling and facilitated the family to make an evidence-based decision for conception and also alleviated the extreme degree of anxiety associated with the thought of having a second child in this set of circumstances.

  14. Methylbromide intoxication: a clinical case study.

    PubMed

    Breeman, Wim

    2009-01-01

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent. PMID:20118865

    PubMed

    Ross, Thomas K

    2006-01-01

    Statistical process control (SPC) charts can be applied to a wide number of health care applications, yet widespread use has not occurred. The greatest obstacle preventing wider use is the lack of quality management training that health care workers receive. The technical nature of the SPC guarantees that without explicit instruction this technique will not come into widespread use. Reviews of health care quality management texts inform the reader that SPC charts should be used to improve delivery processes and outcomes often without discussing how they are created. Conversely, medical research frequently reports the improved outcomes achieved after analyzing SPC charts. This article is targeted between these 2 positions: it reviews the SPC technique and presents a tool and data so readers can construct SPC charts. After tackling the case, it is hoped that the readers will collect their own data and apply the same technique to improve processes in their own organization. PMID:17047496

    2012-06-01

    Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia. PMID:21453912

    Doody, Owen; Doody, Catriona M

    Pilot studies play a vital role in health research, but are often misused, mistreated and misrepresented. A well-conducted pilot study with clear aims and objectives within a formal framework ensures methodological rigour, can lead to higher-quality research and scientifically valid work that is publishable and can benefit patients and health service delivery. A pilot study contributes valuable information to assist researchers in the conduct of their study. Conducting a pilot study provides the researcher with the opportunity to develop and enhance the skills necessary before commencing the larger study. By conducting a pilot the researcher obtains preliminary data, can evaluate their data-analysis method and clarify the financial and human resources required. This article presents an overview of pilot studies, why they are conducted, what to consider when reporting pilot studies and the authors' experience of conducting a pilot study. To conduct a successful study, researchers need to develop their skills, choose the right methods and carefully plan for all aspects of the process. PMID:26618678

  1. A case study in evolutionary contingency.

    PubMed

    Blount, Zachary D

    2016-08-01

    Biological evolution is a fundamentally historical phenomenon in which intertwined stochastic and deterministic processes shape lineages with long, continuous histories that exist in a changing world that has a history of its own. The degree to which these characteristics render evolution historically contingent, and evolutionary outcomes thereby unpredictably sensitive to history has been the subject of considerable debate in recent decades. Microbial evolution experiments have proven among the most fruitful means of empirically investigating the issue of historical contingency in evolution. One such experiment is the Escherichia coli Long-Term Evolution Experiment (LTEE), in which twelve populations founded from the same clone of E. coli have evolved in parallel under identical conditions. Aerobic growth on citrate (Cit(+)), a novel trait for E. coli, evolved in one of these populations after more than 30,000 generations. Experimental replays of this population's evolution from various points in its history showed that the Cit(+) trait was historically contingent upon earlier mutations that potentiated the trait by rendering it mutationally accessible. Here I review this case of evolutionary contingency and discuss what it implies about the importance of historical contingency arising from the core processes of evolution. PMID:26787098

  3. Combining genetic association study designs: a GWAS case study.

    PubMed

    Estus, Janice L; Fardo, David W

    2013-01-01

    Genome-wide association studies (GWAS) explore the relationship between genome variability and disease susceptibility with either population- or family-based data. Here, we have evaluated the utility of combining population- and family-based statistical association tests and have proposed a method for reducing the burden of multiple testing. Unrelated singleton and parent-offspring trio cases and controls from the Genetics of Kidneys in Diabetes (GoKinD) study were analyzed for genetic association with diabetic nephropathy (DN) in type 1 diabetics (T1D). The Cochran-Armitage test for trend and the family-based association test were employed using either unrelated cases and controls or trios, respectively. In addition to combining single nucleotide polymorphism (SNP) p-values across these tests via Fisher's method, we employed a novel screening approach to rank SNPs based on conditional power for more efficient testing. Using either the population-based or family-based subset alone predictably limited resolution to detect DN SNPs. For 384,197 SNPs passing quality control (QC), none achieved strict genome-wide significance (1.4 × 10(-7)) using 1171 singletons (577/594 cases/controls) or 1738 pooled singletons and offspring probands (841/897). Similarly, none of the 352,004 SNPs passing QC in 567 family trios (264/303 case/control proband trios) reached genome-wide significance. Testing the top 10 SNPs ranked using aggregated conditional power resulted in two SNPs reaching genome-wide significance, rs11645147 on chromosome 16 (p = 1.74 × 10(-4) < 0.05/10 = 0.005) and rs7866522 on chromosome 9 (p = 0.0033). Efficient usage of mixed designs incorporating both unrelated and family-based data may help to uncover associations otherwise difficult to detect in the presence of massive multiple testing corrections. Capitalizing on the strengths of both types while using screening approaches may be useful especially in light of large-scale, next-generation sequencing and rare

    A joint study has been conducted by NASA and Army installations collocated in a dense forest in southwestern Mississippi in order to determine the technical and economic feasibility of using wood waste as a renewable energy source. The study has shown that, with proper forest management, the timber on government lands could eventually support the total energy requirements of 832 billion Btu/yr. Analysis of the current conversion technologies indicates that the direct combustion spreader stoker approach is the best demonstrated technology for this specific application. The economics of the individual powerplants reveal them as attractive alternatives to fossil fueled plants. Environmental aspects are also discussed.

    In 1992, Kiss Cathcart Anders Architects performed a study for NREL on Building-Integrated Photovoltaics (BIPV) issues as seen from the perspective of the building community. In general, the purpose of the study was to list major issues and potential applications; by it`s nature it asked more questions than it answered. This second phase study was to produce quantitative data on the performance of specific BIPV systems. Only roof systems are evaluated. The energy performance, construction cost and simple payback for five different BIPV roof options are evaluated in six different locations: Oakland, New York, Miami, Phoenix, Chicago, and Cincinnati. The roof options evaluated include the following: single-glazed PV roof using glass-substrate PVs; double-glazed PV roof with insulating PV modules; ballasted roof-mounted system; sawtooth light monitor roof with indirect north daylighting; sawtooth roof with north light and active heat recovery.

  17. Prosodic deviation in dysarthria: a case study.

    PubMed

    Vance, J E

    1994-01-01

    Traditionally, prosodic difficulties in dysarthria have been described in phonetic terms with little attention being paid to the phonological implications of these impairments. This cast study attempts to illustrate the need for a phonological level of analysis. The speech of a 30-year-old ataxic dysarthric is analysed using Crystal's framework and the patterns are discussed in terms of the effect of the phonetic difficulties on the speaker's ability to use his intonation system to mark meaning contrasts. The analysis reveals that this speaker has developed a personal subsystem where he retains some of the features of 'normal' speech and systematically exploits variables still under his control to compensate for other deficits. This study highlights both the value of considering phonological aspects in the analysis of disordered prosody and the need for careful assessment of the appropriacy of the compensatory strategies that have been developed.

    2014-01-01

    Introduction: The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best. Materials and Methods: A prospective study of 80 patients who underwent ossiculoplasty was performed in the ear, nose, and throat (ENT) department at a tertiary health care facility from 2011 to 2013. Patients with chronic suppurative otitis media with an air-bone gap (ABG) of >25 dB with ossicular involvement were included in the study. Total ossicular replacement prosthesis (TORP), partial ossicular replacement prosthesis (PORP), and refashioned incus were used. Success was defined as ABG <25 dB on postoperative Day 90. Results: The majority patients were of middle age with moderate conductive hearing loss. Incus was the most susceptible ossicle. Overall success rate in this study was 80.0% with an average change of 15.76 dB in ABG. Conclusion: With continuing advances in our understanding of middle ear mechanics, the results of ossiculoplasty are improving and results can be very rewarding in experienced hands. Severity of preoperative ear discharge, preoperative mastoid cellularity, presence of disease, and surgical procedure proved to be significant prognostic factors. Autograft incus and PORP fared better when the malleus handle was present while TORP gave better results when the malleus handle was eroded. PMID:25009804

  1. A Psychophysiological Case Study of Orchestra Conductors.

    PubMed

    Jaque, S Victoria; Karamanukyan, Isabel H; Thomson, Paula

    2015-12-01

    The psychological and physiological effects of performance were investigated in two professional orchestral conductors, with data collected prior to, during, and after a rehearsal and a public performance. The participants were given a battery of psychological self-report tests (anxiety, dissociation, health inventory, fantasy proneness, shame, and flow). Ambulatory physiological monitoring (Vivometric LifeShirt® system) was conducted during both a rehearsal and public performance to gather information about the autonomic nervous system and heart rate variability (HRV). One conductor had a history of asthma and anxiety, and the second conductor had coronary artery disease. The results revealed within-subject and between-subject differences in autonomic nervous system responses and HRV during several conditions (pre-performance rest, stair-climbing, rehearsal, and performance). Based on heart rate, the physiological demands of professional conducting are reflective of work intensities considered "hard." Both conductors experienced high flow states. Anxiety and coronary artery disease may have attenuated HRV resilience in this study. It is recommended that noninvasive methods be implemented to assess cardiac autonomic activity in professional conductors, particularly during engagement in their professional activities. The findings suggest a need to further study anxiety, respiratory conditions, and cardiovascular risks for conductors. PMID:26614972

    1991-01-01

    Alternatives are reviewed for accessing distributed heterogeneous databases and a recommended solution is proposed. The current study is limited to the Automated Information Systems Center at the Naval Sea Combat Systems Engineering Station at Norfolk, VA. This center maintains two databases located on Digital Equipment Corporation's VAX computers running under the VMS operating system. The first data base, ICMS, resides on a VAX11/780 and has been implemented using VAX DBMS, a CODASYL based system. The second database, CSA, resides on a VAX 6460 and has been implemented using the ORACLE relational database management system (RDBMS). Both databases are used for configuration management within the U.S. Navy. Different customer bases are supported by each database. ICMS tracks U.S. Navy ships and major systems (anti-sub, sonar, etc.). Even though the major systems on ships and submarines have totally different functions, some of the equipment within the major systems are common to both ships and submarines.

    NASA Technical Reports Server (NTRS)

    Aydt, Ruth; Gunter, Dan; Quesnel, Darcy; Smith, Warren; Taylor, Valerie; Biegel, Bryan (Technical Monitor)

    2001-01-01

    This document presents a simple case study of a Grid performance system based on the Grid Monitoring Architecture (GMA) being developed by the Grid Forum Performance Working Group. It describes how the various system components would interact for a very basic monitoring scenario, and is intended to introduce people to the terminology and concepts presented in greater detail in other Working Group documents. We believe that by focusing on the simple case first, working group members can familiarize themselves with terminology and concepts, and productively join in the ongoing discussions of the group. In addition, prototype implementations of this basic scenario can be built to explore the feasibility of the proposed architecture and to expose possible shortcomings. Once the simple case is understood and agreed upon, complexities can be added incrementally as warranted by cases not addressed in the most basic implementation described here. Following the basic performance monitoring scenario discussion, unresolved issues are introduced for future discussion.

  12. Cirrus cloud iridescence: a rare case study.

    PubMed

    Sassen, Kenneth

    2003-01-20

    On the evening of 25 November 1998, a cirrus cloud revealing the pastel colors of the iridescence phenomenon was photographed and studied by a polarization lidar system at the University of Utah Facility for Atmospheric Remote Sensing (FARS). The diffraction of sunlight falling on relatively minute cloud particles, which display spatial gradients in size, is the cause of iridescence. According to the 14-year study of midlatitude cirrus clouds at FARS, cirrus rarely produce even poor iridescent patches, making this particularly long-lived and vivid occurrence unique. In this unusually high (13.2-14.4-km) and cold (-69.7 degrees to -75.5 degrees) tropopause-topped cirrus cloud, iridescence was noted from approximately 6.0 degrees to approximately 13.5 degrees from the Sun. On the basis of simple diffraction theory, this indicates the presence of particles of 2.5-5.5-microm effective diameter. The linear depolarization ratios of delta = 0.5 measured by the lidar verify that the cloud particles were nonspherical ice crystals. The demonstration that ice clouds can generate iridescence has led to the conclusion that iridescence is rarely seen in midlatitude cirrus clouds because populations of such small particles do not exist for long in the presence of the relatively high water-vapor supersaturations needed for ice-particle nucleation.

  13. A case study in scanner optimisation

    PubMed Central

    Gibson, NM

    2013-01-01

    Ultrasound scanner preset programmes are factory set or tailored to user requirements. Scanners may, therefore, have different settings for the same application, even on similar equipment in a single department. The aims of this study were: (1) to attempt to match the performance of two scanners, where one was preferred and (2) to assess differences between six scanners used for breast ultrasound within our organisation. The Nottingham Ultrasound Quality Assurance software was used to compare imaging performance. Images of a Gammex RMI 404GS test object were collected from six scanners, using default presets, factory presets and settings matched to a preferred scanner. Resolution, low contrast performance and high contrast performance were measured. The performance of two scanners was successfully matched, where one had been preferred. Default presets varied across the six scanners, three different presets being used. The most used preset differed in settings across the scanners, most notably in the use of different frequency modes. The factory preset was more consistent across the scanners, the main variation being in dynamic range (55–70 dB). Image comparisons showed significant differences, which were reduced or eliminated by adjustment of settings to match a reference scanner. It is possible to match scanner performance using the Nottingham Ultrasound Quality Assurance software as a verification tool. Ultrasound users should be aware that scanners may not behave in a similar fashion, even with apparently equivalent presets. It should be possible to harmonise presets by consensus amongst users.

    2015-12-01

    Drought is among the natural disaster that causes damages and affects many people's life in many part of the world including in Iran. Recently, some factors such as climate variability and the impact of climate change have influenced drought frequency and intensity in many parts of the world. Drought can be divided into four categories of meteorological, hydrological, agricultural and social-economic. In meteorological the important feature is lack of rainfall. In hydrological drought river flows and dam storage are considered. Lack of soil moisture is the key factor in agricultural droughts while in social-economic type of drought the relation between supply and demand and social-economic damages due to water deficiency is studied. While the first three types relates to the lack of some hydrological characteristics, social-economic type of drought is actually the consequence of other types expressed in monetary values. Many indices are used in assessing drought; each has its own advantages and disadvantages and can be used for specific types of drought. Therefore knowing the types of drought can provide a better understanding of shortages and their characteristics. Drought vulnerability is a concept which shows the likelihood of damages from hazard in a particular place by focusing on the system status prior to the disaster. Drought vulnerability has been viewed as a potential for losses in the region due to water deficiency at the time of drought. In this study the application of vulnerability concept in drought management in East Azarbaijan province in Iran is investigated by providing vulnerability maps which demonstrates spatial characteristics of drought vulnerability. In the first step, certain governing parameters in drought analysis such as precipitation, temperature, land use, topography, solar radiation and ground water elevation have been investigated in the region. They are described in details and calculated in suitable time series. Vulnerabilities

    1976-01-01

    The managers of the NASA Scientific and Technical Information System consistently maintain that whatever scientific and technical information services and products are provided must be geared primarily to user needs and not simply system compatibility and convenience. A system evaluation study begun in 1973 and continued to the present is described. The thrust of this on-going examination is to regularly evaluate the usefulness of the present information system to those it is intended to serve, engineers and scientists working in their professional roles, and to identify areas and ways in which the system can be made more responsive to user needs. Techniques used have covered the range from personal, in-depth interviews to widely distributed questionnaires. The findings have been positive. Many refinements made to on-going programs and projects and new endeavors begun in direct response to stated user needs are discussed. In the main these needs are not unreasonable and thus can be responded to with cost effective system modifications.

  14. A Case for Hypogravity Studies Aboard ISS

    NASA Technical Reports Server (NTRS)

    Paloski, William H.

    2014-01-01

    Future human space exploration missions being contemplated by NASA and other spacefaring nations include some that would require long stays upon bodies having gravity levels much lower than that of Earth. While we have been able to quantify the physiological effects of sustained exposure to microgravity during various spaceflight programs over the past half-century, there has been no opportunity to study the physiological adaptations to gravity levels between zero-g and one-g. We know now that the microgravity environment of spaceflight drives adaptive responses of the bone, muscle, cardiovascular, and sensorimotor systems, causing bone demineralization, muscle atrophy, reduced aerobic capacity, motion sickness, and malcoordination. All of these outcomes can affect crew health and performance, particularly after return to a one-g environment. An important question for physicians, scientists, and mission designers planning human exploration missions to Mars (3/8 g), the Moon (1/6 g), or asteroids (likely negligible g) is: What protection can be expected from gravitational levels between zero-g and one-g? Will crewmembers deconditioned by six months of microgravity exposure on their way to Mars experience continued deconditioning on the Martian surface? Or, will the 3/8 g be sufficient to arrest or even reverse these adaptive changes? The implications for countermeasure deployment, habitat accommodations, and mission design warrant further investigation into the physiological responses to hypogravity. It is not possible to fully simulate hypogravity exposure on Earth for other than transient episodes (e.g., parabolic flight). However, it would be possible to do so in low Earth orbit (LEO) using the centrifugal forces produced in a live-aboard centrifuge. As we're not likely to launch a rotating human spacecraft into LEO anytime in the near future, we could take advantage of rodent subjects aboard the ISS if we had a centrifuge that could accommodate the rodent

    PubMed Central

    Bagán, Jose V.; Sanchis, Jose M.; Carbonell, Enrique

    2012-01-01

    Objective: To compare the risk factors and clinical manifestations of patients with temporomandibular disorders (TMDs) diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (axis I) versus an age and gender matched control group. Study Design: A total of 162 patients explored according to the RDC/TMD (mean age 40.6±18.8 years, range 7-90; 11.1% males and 88.9% females) were compared with 119 controls, measuring differences in TMD risk factors (sleep disturbances, stress, psychoactive medication, parafunctions, loss of posterior support, ligament hyperlaxity) and clinical variables (joint sounds, painful muscle and joint palpation, maximum aperture). Results: Myofascial pain (MFP) (single or multiple diagnoses) was the most frequent diagnosis (42%). The most common diagnostic combination was MFP plus arthralgia (16.0%). Statistically significant differences were observed in clenching (OR 2.3; 95%CI: 1.4-3.8) and in maximum active aperture (MAA) on comparing the two groups both globally (TMD vs. controls) (patients 36.7±8.6 mm, controls 43.1±5.8 mm; F=45.41, p = 0.000) and on comparing according to diagnostic categories. MFP explained most of the observed differences in the risk factors: stress perception (OR=1.98;I.C.:1.01-3.89), psychoactive medication (OR=2.21; I.C.:1.12-4.37), parafunctions (OR=2.14;I.C.:1.12-4.11), and ligament laxity (OR=2.6;I.C.:1.01-6.68). Joint sounds were more frequent in patients with MFP (39.7% vs. 24.0%; χ2=4.66; p=0.03), and painful joint palpation was more common in patients with disc displacement with reduction (DDWR)(15.9% vs. 5.0%; χ2 = 5.2; p = 0.02) and osteoarthrosis (20.8% vs. 5.0%; χ2 = 7.0; p = 0.008). Conclusions: There is a high prevalence of signs and symptoms of TMDs in the general population. Significant differences are observed in clenching and MAA between patients and controls considered both globally and for each diagnostic category individually. The analyzed risk

  16. Tephrochronology: a New Zealand case study

    NASA Astrophysics Data System (ADS)

    Shane, Phil

    2000-03-01

    Tephrochronology is the study of volcanic ash (tephra) beds for the purpose of correlating and dating volcanic and other geologic events. Large magnitude silicic eruptions can disperse tephra up to thousands of kilometres from the vent, producing a near instantaneous marker horizon. In addition to their geochronological value, tephra beds are a major source of data on the eruption frequency and geochemistry of large rhyolitic volcanoes. The Quaternary Taupo volcanic zone (TVZ) in New Zealand is one of the most frequently active rhyolitic centres on Earth, and for much of the 20th century its tephra beds have been the focus of study. As a result, fingerprinting and dating techniques have been fine-tuned, and tephra beds now under-pin the late Cenozoic chronology for a wide variety of disciplines from volcanology to sequence stratigraphy and archaeology. The key to tephrochronology is the identification and correlation of tephra horizons. In the proximal setting (<50 km from vent), tephra beds can often be identified by their lithology, stratigraphic position and ferromagnesian mineralogy. Farther from source these features became less diagnostic as units become thinner and mineral depleted, and geochemical fingerprinting must then be employed. Grain-specific techniques are commonly required to assess the compositional homogeneity of the tephra, and to avoid xenolithic and detrital contaminants. Criteria that are valuable for identifying both source volcano and individual eruptive events from grain-specific electron microprobe techniques include: glass and Fe-Ti oxide chemistry, and eruption temperature and oxygen fugacity (estimated from oxide equilibrium pairs). Deposits of the contemporaneously active Taupo, Okataina, Maroa and Mayor Island caldera centres in the TVZ can be distinguished on the basis of such criteria. If a tephra lacks contaminants, trace- and rare earth element (REE) compositions of purified glass separates provide additional criteria. Similar

    Cellular angiofibroma is a mesenchymal tumor that affects both genders. Nucci et al. first described it in 1997. Cellular angiofibroma is generally a small and asymptomatic mass that primarily arises in the vulvar-vaginal region, although rare cases have been reported in the pelvic and extrapelvic regions. It affects women most often during the fifth decade of life. The treatment requires simple local excision due to low local recurrence and no chance of metastasization. The current study presents a case of angiofibroma in the vulvar region that measured approximately 20 cm. PMID:27293929

    Standard arguments for and against sex preselection, i.e., choosing the sex of one's child prior to conception, are reviewed. Sex preselection is then considered from a feminist perspective which attempts to maximize clusters of values rather than unnecessarily trying to choose the most important value. From this perspective, a reasonable stance would be not to opt for a girl or a boy, but to plan and welcome each child. PMID:11658642

    Estimating certain attributes within a geological body whose exact boundary is not known presents problems because of the lack of information. Estimation may result in values that are inadmissible from a geological point of view, especially with attributes which necessarily must be zero outside the boundary, such as the thickness of the oil column outside a reservoir. A simple but effective way to define the boundary is to use indicator kriging in two steps, the first for the purpose of extrapolating control points outside the body, the second to obtain a weighting function which expresses the uncertainty attached to estimations obtained in the boundary region. ?? 1993 International Association for Mathematical Geology.

    A dean at a private school of nursing implemented a leadership development program for early- to mid-career nursing faculty consisting of one 4-hour evening session per academic quarter for 7 quarters. Eight faculty members who had expressed interest in assuming a leadership role or been recommended by their supervisors as having strong leadership potential were invited to join. Program topics included leadership pathways, legal issues, budgeting and governance, diversity, the political arena, human resources, and student issues. Interviews with participants revealed 6 themes: the support a peer cohort provided, a desire for real-life application, a lack of previous exposure to related content or experiences, new perceptions of themselves as academic nurse leaders, the value of the program as preparation for academic nursing leadership roles, and broad program applicability.

    SciTech Connect

    LoFaro, T.; Kopell, N.

    1995-12-31

    We discuss a method by which the dynamics of a network of coupled neurons can be captured in a one-dimensional map. The network used as an example of this technique consists of a pair of neurons, one of which is an endogenous burster and the other excitable, but not bursting in the absence of phasic input. The reduction is accomplished by decomposing the flow into fast and slow subsystems, each operating on a distinct time scale. A {open_quotes}map of knees{close_quotes} is constructed using singular perturbation techniques. A concise expression for this map is developed by introducing time coordinates to each stable branch of the slow manifold. The compression associated with the fast subsystem is used to determine the qualitative properties of the map.

    Observations of a pulsating aurora event occurring on 11 February 2008, using the Time History of Events and Macroscale Interactions during Substorms (THEMIS) All-Sky Imager (ASI) array, indicate a spatially and temporally continuous event with a duration of greater than 15 h and covering a region with a maximum size of greater than 10 h magnetic local time. The optical pulsations are at times locally interrupted or drowned out by auroral substorm activity but are observed in the same location once the discrete aurora recedes. The pulsations following the auroral breakup appear to be brighter and have a larger patch size than before breakup. This suggests that, while the onset of pulsating aurora is not necessarily dependent upon a substorm precursor, the pulsations are affected and possibly enhanced by the substorm process. The long duration of this pulsating aurora event, lasting approximately 8 h without interruption as imaged from Gillam station, is significantly longer than the typical 2-3 h substorm recovery phase, suggesting that pulsating aurora is not strictly a recovery phase phenomenon. This paper is accompanied by a movie of the THEMIS ASI array data, from 0000 to 1715 UT, plotted in mosaic and superimposed onto a map of North America.

    Moore, G. W. K.

    2004-11-01

    A plume of snow blowing from the summit of Mount Everest is one of the most iconic images of the world's highest mountain. Its presence provides evidence of the strong jet stream winds that can buffet the mountain. In January 2004, astronauts onboard the International Space Station (ISS) observed a 15 to 20 km long snow plume emanating from the summit of Mount Everest. Remarkably little is known about these plumes and the role that they play in the redistribution of snow in the high Himalaya. In this paper we use a variety of meteorological datasets to show that the observed plume was the combination of high winds associated with the East Asian Jet Stream (EAJS) and a heavy snowfall that had occurred over the Himalaya during the preceding week. A simple model of a blown snow plume is shown to be consistent with the observations made from the ISS.

The CT scan showed the presence of a left orbital wood foreign body extended to the homolateral cavernous sinus and intracranial. Extraction of the wood fragment associated with an adapted antibiotic treatment led to clinical improvement without visual recovery. A situation of orbital trauma and secondary orbital inflammatory syndrome must raise the suspicion of a foreign body of the orbit and motivate emergency imaging for optimal management of the disorder.

    To attain and sustain a competitive advantage organizations are continually faced with the need to change their structures, processes and technologies. Converting to new technology and implementing a new information management system in an organization results in inevitable changes in organizational procedures impacting on the people involved. A major problem encountered during this process is resistance to change, which may contribute to total failure of this system. Change management is the process that can be used to negate this impact and assist employees in transitioning to a new way of doing things.

    Pozos-Estrada, Oscar; Fuentes-Mariles, Oscar A; Pozos-Estrada, Adrian

    2012-01-01

    This paper presents a case study of an existing wastewater rising main (WWRM) in which an extreme transient event produced by simultaneous power failure of the pumps caused the rupture of a 1.2 m (48 in) prestressed concrete cylinder pipe (PCCP), causing an important leakage of sewage. The event and the methodology followed in order to validate the diagnostics of the failure are described. The detail study included in situ observation of the system, experimental investigation in a setup, hydraulic analysis, as well as details of the structural strength of the WWRM. After the extensive investigation and several simulations of fluid transients for different scenarios and flow conditions, it was found that stationary small gas pockets accumulated at high points of the WWRM were identified as the principal contributory factor of the failure. This case study serves as clear warning of the consequences of operating a WWRM with gas pockets at its high points. PMID:22949261

The Loughborough Innovation Platform for Health Technologies (LIPHT) can be used to demonstrate the use of the research and innovation pipe-line in more than one dimension. For this paper the first dimension considered is that of 'blue sky' idea through to their exploitation for the benefit of users and at the same time creating a wealth stream; the second dimension is the changing market as the ideas develop--from a hospital-based instrument operated by clinicians through to a point and click device for the use by the knowledgeable layman in the community. The starting point for these developments is a medical device known to many people as the 'finger clip' that measures arterial blood oxygen saturation; the end point is an optical device capable of imaging blood perfusion.

    The aim of this paper was to discuss how words for symptoms relate to experience and to find out how seriously ill patients two years after diagnosis and treatment articulated suffering. Nine patients who have had a cancer tumour of the central nervous system were interviewed in their homes and the findings were interpreted in a hermeneutic process. Bodily, obstructive, emotive and metaphorical expressions of symptoms appeared. The transformed life situation involved inability to perform everyday tasks and a feeling of frustration of needs and desires. The words for symptoms conveyed individual embodied experience connected to a discourse of shared meanings. The relationship between individuality and culture means that words for symptoms are created and understood in a process between patient and listener, between discourse, culture and history.

    1992-01-01

    Total Quality Management (TQM) is becoming more important as a way to improve productivity. One of the technical aspects of TQM is a system called the Taguchi method. This is an optimization method that, with a few precautions, can reduce test effort by an order of magnitude over conventional techniques. The Taguchi method is specifically designed to minimize a product's sensitivity to uncontrollable system disturbances such as aging, temperature, voltage variations, etc., by simultaneously varying both design and disturbance parameters. The analysis produces an optimum set of design parameters. A 3-day class on the Taguchi method was held at the Marshall Space Flight Center (MSFC) in May 1991. A project was needed as a follow-up after the class was over, and the motor controller was selected at that time. Exactly how to proceed was the subject of discussion for some months. It was not clear exactly what to measure, and design kept getting mixed with optimization. There was even some discussion about why the Taguchi method should be used at all.

    One of the important and usual missed causes of pediatric traumas is child abuse. This ominous phenomenon, which can be presented physically, psychologically, sexually, and emotionally has grown significantly in recent years. Many children are not diagnosed in the early stages of evaluation. Battered Child Syndrome is used to describe the clinical condition of the child serious physical abuse by parents or caregivers. Medical staff should always keep the syndrome in their mind for those brought to the emergency department with trauma. In this report, we described a patient complained of dysphagia following a falling from a height and multiple epidural hematomas and final diagnosis of battered child syndrome. PMID:26495388

  4. Validating Cyber Security Requirements: A Case Study

    SciTech Connect

    Abercrombie, Robert K; Sheldon, Frederick T; Mili, Ali

    2011-01-01

    Vulnerabilities in a system may have widely varying impacts on system security. In practice, security should not be defined as the absence of vulnerabilities. In practice, security should not be quantified by the number of vulnerabilities. Security should be managed by pursuing a policy that leads us first to the highest impact vulnerabilities. In light of these observations, we argue in favor of shifting our focus from vulnerability avoidance/removal to measurable security attributes. To this effect, we recommend a logic be used for system security, which captures/represents security properties in quantifiable, verifiable, measurable terms so that it is possible to reason about security in terms of its observable/perceptible effects rather than its hypothesized causes. This approach is orthogonal to existing techniques for vulnerability avoidance, removal, detection, and recovery, in the sense that it provides a means to assess, quantify, and combine these techniques.

    Little, Lisa

    2007-01-01

    Objective To synthesize information about nurse migration in and out of Canada and analyze its role as a policy lever to address the Canadian nursing shortage. Principal Findings Canada is both a source and a destination country for international nurse migration with an estimated net loss of nurses. The United States is the major beneficiary of Canadian nurse emigration resulting from the reduction of full-time jobs for nurses in Canada due to health system reforms. Canada faces a significant projected shortage of nurses that is too large to be ameliorated by ethical international nurse recruitment and immigration. Conclusions The current and projected shortage of nurses in Canada is a product of health care cost containment policies that failed to take into account long-term consequences for nurse workforce adequacy. An aging nurse workforce, exacerbated by layoffs of younger nurses with less seniority, and increasing demand for nurses contribute to a projection of nurse shortage that is too great to be solved ethically through international nurse recruitment. National policies to increase domestic nurse production and retention are recommended in addition to international collaboration among developed countries to move toward greater national nurse workforce self sufficiency.

  7. Assessing Biofuel Crop Invasiveness: A Case Study

    PubMed Central

    Buddenhagen, Christopher Evan; Chimera, Charles; Clifford, Patti

    2009-01-01

    Background There is widespread interest in biofuel crops as a solution to the world's energy needs, particularly in light of concerns over greenhouse-gas emissions. Despite reservations about their adverse environmental impacts, no attempt has been made to quantify actual, relative or potential invasiveness of terrestrial biofuel crops at an appropriate regional or international scale, and their planting continues to be largely unregulated. Methodology/Principal Findings Using a widely accepted weed risk assessment system, we analyzed a comprehensive list of regionally suitable biofuel crops to show that seventy percent have a high risk of becoming invasive versus one-quarter of non-biofuel plant species and are two to four times more likely to establish wild populations locally or be invasive in Hawaii or in other locations with a similar climate. Conclusions/Significance Because of climatic and ecological similarities, predictions of biofuel crop invasiveness in Hawaii are applicable to other vulnerable island and subtropical ecosystems worldwide. We demonstrate the utility of an accessible and scientifically proven risk assessment protocol that allows users to predict if introduced species will become invasive in their region of interest. Other evidence supports the contention that propagule pressure created by extensive plantings will exacerbate invasions, a scenario expected with large-scale biofuel crop cultivation. Proactive measures, such as risk assessments, should be employed to predict invasion risks, which could then be mitigated via implementation of appropriate planting policies and adoption of the “polluter-pays” principle.

    The performance of several coating systems were tested for immersion exposure in potable water storage tank service. Tests were performed for a period of several months in-situ by application of coating systems test patches to a tank interior and was examined periodically during normal service operation. Concurrent with test patches, prepared test panels were placed in the immersion and vapor zones of the tank. Also, test panels were subjected to immersion and condensing humidity in a laboratory environment. All systems were applied in accordance with the respective manufacturers recommendations. Two levels of abrasive blast surface preparation were employed, SSPC-SP10 and SSPC-SP6. Coal slag and sodium bicarbonate were used as blast media. Additionally, some panels and selected tank areas were intentionally subjected to surface contamination in the form of soluble salts to assess the relative tolerance of the selected system to such steel substrate contamination.

    Southern California Edison currently operates its Residential Air Conditioner Cycling Program as a production program on a systemwide basis. Air conditioner cycling enables Edison to cycle, or switch off, at predetermined intervals, approximately 100,000 air conditioners throughout the Edison service areas. Activation of this system reduces peak demands for load shaping capability. Benefits of this method of peak reduction include the potential for system load factor improvement and/or for deferral of construction of new generation facilities. Edison began testing hardware for direct load control in 1976. Experimental test programs were implemented from 1978 through 1980. These successful test programs resulted in the decision to implement the Residential Air Conditioner Cycling Program on a systemwide basis in 1983.

    2002-01-01

    Channelization of the Kissimmee River transformed a 167 km meandering river into a 9 metre deep, 75 metre wide, 90 km drainage canal (C-38) that is compartmentalized with levees and water control structures into a series of five stagnant pools. Channelization dramatically changed water level and flow characteristics, drained 21,000 hectares of floodplain wetlands and severely impacted fish and wildlife populations. A $500 million dollar restoration project will restore the ecological integrity of the river-floodplain system by reconstructing the natural river channel and reestablishing hydrologic processes. Sixty expectations have been established to quantify the ecosystem's recovery. The first phase of reconstruction was completed in February 2001 and included movement of 9.2 million cubic metres of earth to backfill 12 km of C-38, the explosive demolition of one water control structure, construction of two sections (2.4 km) of new river channel, and reestablishment of 24 contiguous km of river. Numerous social, political, and technical challenges have been encountered during the project's evolution. Recommendations are provided for future restoration projects. PMID:12171366

    The Drosophila (fruit fly) model system has been instrumental in our current understanding of human biology, development, and diseases. Here, we used a high-throughput yeast two-hybrid (Y2H)-based technology to screen 102 bait proteins from Drosophila melanogaster, most of them orthologous to human cancer-related and/or signaling proteins, against high-complexity fly cDNA libraries. More than 2300 protein-protein interactions (PPI) were identified, of which 710 are of high confidence. The computation of a reliability score for each protein-protein interaction and the systematic identification of the interacting domain combined with a prediction of structural/functional motifs allow the elaboration of known complexes and the identification of new ones. The full data set can be visualized using a graphical Web interface, the PIMRider (http://pim.hybrigenics.com), and is also accessible in the PSI standard Molecular Interaction data format. Our fly Protein Interaction Map (PIM) is surprisingly different from the one recently proposed by Giot et al. with little overlap between the two data sets. Analysis of the differences in data sets and methods suggests alternative strategies to enhance the accuracy and comprehensiveness of the post-genomic generation of broad-scale protein interaction maps.

    Achieving the goal of a diverse, internationally competitive, and globally engaged workforce of scientists, engineers, and well prepared citizens calls for renewed educational goals and strategies. In 1995 UCAR teamed up with NSF and established a program, SOARS, that extends science education and encourages university students from diverse backgrounds to nourish their interests, develop skills, and create paths that lead them to careers in the atmospheric and related sciences. SOARS integrates multi-summer research opportunities with a comprehensive mentoring component and other proven learning strategies to create a student (protégé) centered learning community. SOARS is having a positive impact on the scientific community. Already more that 60 protégés have traveled this pathway; several are successfully employed as scientists. Nine have attained graduate degrees, three are Ph.D. candidates, and 34 have received undergraduate degrees. In fall 2001, 17 SOARS protégés are enrolled in graduate programs in the atmospheric and related sciences. Many have participated in scientific conferences and coauthored papers published in peer-reviewed journals. SOARS sponsorship has expanded and includes DOE, NASA, and NOAA. Strategies contributing to the success of SOARS include an accrediting disposition that: 1) recognizes protégés as capable, competent, responsible, successful adults and 2) deploys organized activities designed to encourage protégés to see themselves as eligible to become successful scientists while being in good standing in their "home" communities. Relationships with professional scientists and scientific societies that share this disposition have been critical to the success of SOARS.

    2012-01-01

    In a competitive healthcare sector, hospitals have to focus on their processes in order to deliver high-quality care while at the same time reducing costs. Many hospitals have decided to adopt one or another Enterprise Resource Planning (ERP) system to improve their businesses, but implementing an ERP system can be a demanding endeavour. The systems are so difficult to implement that some are successful; many have failed, causing multimillion dollar losses. The challenge of ERP solutions lie in implementation because they are complex, time consuming and expensive too. This paper describes the various process workflows and phases of ERP implementation at Fortis Hospital Cunningham Road, Bangalore, India. This knowledge will provide valuable insights for the researchers and practitioners to understand the different process workflows and to make informed decisions when implementing ERP in any hospital.

    An 81-year-old female was referred for cochlear implantation due to difficulty communicating in her daily activities despite the use of appropriate amplification. The poorer ear was unable to tolerate amplification for the past 15 years. The open-set sentence-recognition test score in quiet in her "good" ear was 85 percent correct, indicating that the patient was not a traditional cochlear implant candidate. However, the sentence-recognition score in noise at +10 dB signal-to-noise ratio was 0 percent, demonstrating a significant breakdown in the patient's speech understanding in more difficult listening situations. This speech-in-noise score appeared to correlate with the patient's reported communication difficulties as well as with the communicative breakdowns that were observed clinically. The patient underwent cochlear implantation in the better ear. Cochlear implantation in this nontraditional patient provided objective and subjective benefit over hearing aid use. PMID:18672646

    Communications and development in the broadest sense of the terms are examined in relation to evaluation of the work of the Communication Foundation for Asia (CFA). CFA produces, in conjunction with public and private development agencies, flip-charts, comics, a fieldworker's handbook for use in family planning education, sound cassette magazines for agricultural extension work, booklets and sound-slides on forming cooperatives, and other educational materials. CFA operates in the Philippines. A developmental radio drama produced by CFA delivered a pro-development message, one that tells people they can do something about their conditions/situations, compared to the passive, consumer-oriented commercial radio drama. The most prominent theme was achievement. The characters had complex motivations and displayed wide range of motives. Like other forms of propaganda, developmental radio drama is not welcomed by radio station owners. Not many people in the industry perceive the opportunity for increasing overall development and economic growth. All pressures from commercial radio are in consumerist directions while developmental drama encourages production. PMID:12261727

    From 2004, the Center for Science Education and Training (CSET) participated to the European Union-funded educational network "Hands-on Science". The aim of the Romanian team was to transform teachers and students from end-users of educational aids to active designers and developers of instructional materials. Several science fields were identified, including photonics. The team at CSET is now focusing on: lasers and their applications, optical fiber communications, solar energy as a sustainable source, and the use of optical spectroscopy in physics and chemistry. CSET initiated an international collaboration with the New England Board of Higher Education (NEBHE) in Boston, Mass., when the Center enrolled an experienced Romanian high school science teacher in a twelve-week "Introduction to Photonics" laboratory-based professional development course. The course was developed by NEBHE through an Advanced Technological Education (ATE) program grant from National Science Foundation and is designed for high school and community college educators from both science and technology instructional areas. The paper reports the experience of this international participation which was made possible since the course is delivered via the Internet by Three Rivers Community College, Norwich, Conn. Its impact on photonics education in Romania and the USA is analyzed, as the participant teacher shares her experiences with teachers and faculty in the "Introduction to Photonics" course and with those enrolled into the Romanian "Hands-on-Science" program.

    2011-01-01

    The use of sustainable drainage systems (SuDS) or best management practice is becoming increasingly common. However, rather than adopting the preferred 'treatment train' implementation, many developments opt for end-of-pipe control ponds. This paper discusses the use of SUDS in series to form treatment trains and compares their potential performance and effectiveness with end-of-pipe solutions. Land-use, site and catchment characteristics have been used alongside up-to-date guidance, Infoworks CS and MUSIC to determine whole-life-costs, land-take, water quality and quantity for different SuDS combinations. The results presented show that the use of a treatment train allows approaches differing from the traditional use of single SuDS, either source or 'end-of-pipe', to be proposed to treat and attenuate runoff. The outcome is a more flexible solution where the footprint allocated to SUDS, costs and water quality can be managed differently to fully meet stakeholder objectives. PMID:21977653

    Partnerships and cooperative agreements abound in the environmental arena today. This paper briefly highlights the collaborative approach used by the International Cooperative for Ozone Layer Protection (ICOLP). ICOLP has helped international members and non-members to eliminate most of the ozone-depleting solvents from manufacturing processes through the exchange of technical information in a non-proprietary manner. By using alternatives, companies and governments have realized savings in the multiple millions of dollars. Advantages of participating in cooperative environmental partnerships may include: (1) improved access and exchange of information, (2) cost minimization, (3) promotion and facilitation of business opportunities, (4) improved dialogue between groups, (5) coordinated approach to complex issues, and (6) technology development and transfer opportunities.

    As the field of collaborative care, or integrated behavioral health, continues to develop, lessons are learned from attempts to establish such programs (Sieber et al., 2012; Unützer, 2014). Part of the success of collaborative care programs is the function of an interdisciplinary team. In this article, faculty from University of San Diego (USD) and University of California, San Diego (UCSD) share changes needed to curriculum and career development to support leadership and teamwork skills essential to program development, implementation, and sustainability for integrated behavioral health. This article uses Unützer's (2014) 4 factors of creating a successful collaborative care program (i.e., shared vision, leadership, staffing, and financial sustainability) to discuss implications for effective collaboration between 2 universities and the training of primary care providers in teamwork and leadership skills for overcoming barriers and pitfalls to expand collaborative care beyond their initial training.

    ,000 sets of 70 red noise series modeled through fractional difference models to have the same red noise persistence as the critical North American AD1400 tree ring network. These calculations regularly resulted in "hockey-stick" shaped PC1s with sharp inflections at the start of the 20th century. We then modeled the resulting 10,000 PC1s against NH temperature and found that the 99 percent RE significance level was 0.59. By this benchmark, the reported RE statistic (0.51) in MBH98 for the AD1400 step lacks statistical significance. Most dendroclimatic reconstructions also provide statistics other than an RE statistic, including R2 and Coefficient of Efficiency, but MBH98 does not and the authors have refused to provide supporting data from which the statistics can be calculated. In our emulations of their calculations, we have been unable to replicate anything close to the reported RE results other than through re-tuning, a procedure not described in MBH98. With a re-tuning step, for the critical AD1400 step, we have obtained an RE of 0.46, but with an R2 of only 0.02 and a CE of minus 0.26, all of which lack statistical significance. This case study illustrates for extreme caution in basing public policy on articles, such as MBH98, whose claims cannot be verified.

    The Socratic function of single case studies (SCSs) is described in its relation to the problem of scientific theory development. Contrary to the traditional point of view, the single case study is not a demonstration or verification of theoretical concepts, but a method of their generation and opportunity for analysis of their interrelations. Considering the case study from the perspective of the Socratic function brings to light important conclusions about the ecological validity of theory development. The essential features of the Socratic function are illustrated using the example of the famous Romantic Essays of Alexandr Luria. PMID:26663629

  6. Chaplaincy and narrative theory: a response to Risk's case study.

    PubMed

    Grossoehme, Daniel H

    2013-01-01

    The response of a clinical chaplain to a case study of chaplaincy with an elderly African-American male with Parkinson's disease is presented. The case study offers two novel aspects: first, it explicitly describes interventions by the chaplain, and second, the chaplain's clinical approach was guided throughout by an underlying theory (narrative theory). The case study seeks to shift the paradigm from chaplains as "agenda-less" companions to clinicians with a repertoire of interventions which they should claim. The chaplain's use of narrative theory is examined. Future case studies may draw on narrative theory in chaplaincy with older males with different chronic disease, with women who have Parkinson's, and may seek to develop a theory of chaplaincy from within the profession.

  10. Epistemological Syncretism in a Biology Classroom: A Case Study

    NASA Astrophysics Data System (ADS)

    Bennett, William D.; Park, Soonhye

    2011-02-01

    In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice. An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations. Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs' beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science. The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they encourage teachers to implement reformed teaching practices.

    PubMed

    Oudman, Erik; Van der Stigchel, Stefan; Postma, Albert; Wijnia, Jan W; Nijboer, Tanja C W

    2014-01-01

    A 54-year-old woman was referred to our Korsakoff Center because of extensive cognitive problems following acute Wernicke's encephalopathy (WE). She had a relatively short history of alcohol abuse and was found lying on the floor in her home by her son. After 5 days without treatment, she was diagnosed with WE in a general hospital. During the course of the disease, minimal change to the acute situation occurred, with chronic confusion, attention deficits, and incoherent behavior symptoms most notable unlike classical Korsakoff's syndrome. Neuropsychological assessment after 4 and 16 months after admission to the hospital revealed global cognitive decline, with striking impairments in attentional, executive, and memory functions. The present case study suggests that the state of confusion and the neuropsychological symptoms in WE can become chronic in case of very late treatment. We therefore recommend that confused alcoholics should receive appropriate parenteral thiamine according to the current clinical standards. PMID:24904442

    Introduction Rupture uterus is a life threatening obstetric complication with serious maternal and fetal side-effects. We report a 3 year (2010-2013) retrospective clinical study of pregnancy with rupture uterus cases attending a tertiary care hospital. Aim The aim of the study was to evaluate the incidence of rupture uterus, incidence as per age, parity, clinical presentations, risk factors, complications and management. Materials and Methods Retrospective data of 74 cases of rupture uterus in SCB Medical college, Cuttack was collected from case records of 26,547 deliveries during a 3 year span (2010-2013). Parameters like cause of rupture, type, site of rupture and outcome were recorded. The collected data was analysed by SPSS software v19. Results Out of 26,547 deliveries during the three year period, there were 74 cases of rupture uterus with an incidence of rupture 1 in 359 (0.28%). The mean age of rupture uterus was 27.4 years. 95.8% were multigravida and majority were referred cases from low socioeconomic status. Only 40.5% had the required minimum of four antenatal visits as recommended by WHO (World Health Organisation). A total of 48.6% of cases with rupture uterus had history of previous Caesarean section. Prolonged labour was present in 75.6% of the cases. Only 12.2% of the cases had history of oxytocin use whereas 9.5% had undergone an operative vaginal delivery. Obstructed labour was the cause in 24.3% of cases, 85.1% had complete rupture. Majority had a rupture in the anterior wall (69%) and 81.1% had rupture in lower segment of uterus. Only 17.6% had broad ligament haematoma, 10.8% colporrhexis and 6.8% had associated bladder injury. Repair was possible in only 39.2% of cases, whereas majority landed up in hysterectomy. Internal iliac ligation was done in 2.7% of cases. Perinatal mortality was 90.5% whereas maternal death was seen in 13.5% cases. One patient developed VVF (vesicovaginal fistula). Duration of hospital stay was upto 14 days in 81

    NASA Technical Reports Server (NTRS)

    Lawrence, Charles; Carney, Kelly; Gallardo, Vicente

    2003-01-01

    The purpose of the present study is to investigate the performance of several existing and new, blade-case interactions modeling capabilities that are compatible with the large system simulations used to capture structural response during blade-out events. Three contact models are examined for simulating the interactions between a rotor bladed disk and a case: a radial and linear gap element and a new element based on a hydrodynamic formulation. The first two models are currently available in commercial finite element codes such as NASTRAN and have been showed to perform adequately for simulating rotor-case interactions. The hydrodynamic model, although not readily available in commercial codes, may prove to be better able to characterize rotor-case interactions.

    Our classrooms are filled with engineering majors who take a semester-long course in static equilibrium. Many students find this class too challenging and drop their engineering major. In our introductory physics class, we often breeze through static equilibrium; to physicists equilibrium is just a special case of Newton's second law. While it is difficult to find more time in the syllabus for any one topic, a hands-on case study may help students to develop their physical intuition about static equilibrium and may help them to succeed in their subsequent classes. This article describes a hands-on case study that you may wish to use in your classroom. (You may also wish to check a case study involving a boat published in this journal in the 1990s. ) The hands-on case study presented here can be easily modified to work at the high school or introductory college level. There are three major components: I) planning, II) doing, and III) calculating.

  18. Model Checking Failed Conjectures in Theorem Proving: A Case Study

    NASA Technical Reports Server (NTRS)

    Pike, Lee; Miner, Paul; Torres-Pomales, Wilfredo

    2004-01-01

    Interactive mechanical theorem proving can provide high assurance of correct design, but it can also be a slow iterative process. Much time is spent determining why a proof of a conjecture is not forthcoming. In some cases, the conjecture is false and in others, the attempted proof is insufficient. In this case study, we use the SAL family of model checkers to generate a concrete counterexample to an unproven conjecture specified in the mechanical theorem prover, PVS. The focus of our case study is the ROBUS Interactive Consistency Protocol. We combine the use of a mechanical theorem prover and a model checker to expose a subtle flaw in the protocol that occurs under a particular scenario of faults and processor states. Uncovering the flaw allows us to mend the protocol and complete its general verification in PVS.

    PubMed

    Maticka-Tyndale, Eleanor; Lewis, Jacqueline; Street, Megan

    2005-02-01

    This case study focused on the steps taken by a Canadian city bordering the United States to manage the commercial sex component of an adult entertainment package that draws many American visitors. It explored how the city dealt with the potential of community stigmatization resulting from its growing reputation as a place for easily accessible sex trade. The distinctive Canadian laws related to the sex industry, the predominantly laissez-faire attitude toward people's sex lives, and concerns about maintaining the atmosphere of safety and privacy protection preferred by many residents set boundaries to the approach that could be taken. The specific historical, geographic, social, and political location of the city figured prominently in its choice of a normalization rather than a spatialization strategy. PMID:15795804

  15. Neurological Fallacies Leading to Malpractice: A Case Studies Approach.

    PubMed

    Johnston, James C; Wester, Knut; Sartwelle, Thomas P

    2016-08-01

    A young woman presents with an intracranial arachnoid cyst. Another is diagnosed with migraine headache. An elderly man awakens with a stroke. And a baby delivered vaginally after 2 hours of questionable electronic fetal monitoring patterns grows up to have cerebral palsy. These seemingly disparate cases share a common underlying theme: medical myths. Myths that may lead not only to misdiagnosis and treatment harms but to seemingly never-ending medical malpractice lawsuits, potentially culminating in a settlement or judgment against an unsuspecting neurologist. This article provides a case studies approach exposing the fallacies and highlighting proper management of these common neurologic presentations. PMID:27445252

    PubMed Central

    Rattanarojsakul, Phichai; Thawesaengskulthai, Natcha

    2013-01-01

    Reaching zero defects is vital in medication service. Medication error can be reduced if the causes are recognized. The purpose of this study is to search for a conceptual framework of the causes of medication error in Thailand and to examine relationship between these factors and its importance. The study was carried out upon an in-depth case study and survey of hospital personals who were involved in the drug use process. The structured survey was based on Emergency Care Research Institute (ECRI) (2008) questionnaires focusing on the important factors that affect the medication safety. Additional questionnaires included content to the context of Thailand's private hospital, validated by five-hospital qualified experts. By correlation Pearson analysis, the result revealed 14 important factors showing a linear relationship with drug administration error except the medication reconciliation. By independent sample t-test, the administration error in the hospital was significantly related to external impact. The multiple regression analysis of the detail of medication administration also indicated the patient identification before administration of medication, detection of the risk of medication adverse effects and assurance of medication administration at the right time, dosage and route were statistically significant at 0.05 level. The major implication of the study is to propose a medication safety model in a Thai private hospital. PMID:23985110

  17. Enrique: A case study of a gifted computer user

    SciTech Connect

    Sesko, S C

    2000-03-17

    The author has been investigating the affective and intellectual views that gifted children have about computers. These studies have used various methodological approaches in order to develop a broad perspective on the issues involved in this topic. The author has used survey instruments (Sesko, 1998) and interview techniques (Sesko, 1999) to capture both statistical and narrative data. The objective of this study is to explore in depth the interactions that one student has with the machine and its applications. The driver for this and the previous studies was the paucity of research in the area of gifted and talented children and their involvement with what has become the primary intellectual tool of the century (Turkel, 1984). The second reason is that it has been posited that the intellectual characteristics of gifted children should enable those who are interested in computers to achieve a high level of proficiency with either computer applications or programming. Further, the ability to learn things at a young age should allow gifted children who use computers to develop a large variety of computer-based activities. The author has shown evidence to support these ideas in previous work. Finally, as Hausman (1985) claims, facilities with computers should allow these children to create new activities for using computers. The author found no published research to demonstrate whether they do; but still believes the results of this case study strongly support Hausman's contentions.

  18. Feet swelling in a multistage ultraendurance triathlete: a case study.

    PubMed

    Knechtle, Beat; Zingg, Matthias Alexander; Knechtle, Patrizia; Rosemann, Thomas; Rüst, Christoph Alexander

    2015-01-01

    Recent studies investigating ultraendurance athletes showed an association between excessive fluid intake and swelling of the lower limbs such as the feet. To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass), foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet increased, percentage body fat decreased, creatinine and urea levels increased, hematocrit and hemoglobin values decreased, and plasma [Na(+)] remained unchanged. The increase in foot volume was significantly and positively related to fluid intake during the stages. The poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. This case report shows that the volume of the foot increased during the ten stages, and the increase in volume was significantly and positively related to fluid intake during the stages. Furthermore, the poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. The continuous feet swelling during the race was most probably due to a combination of a high fluid intake and a progressive decline in renal function (ie, continuous increase in creatinine and urea), leading to body fluid retention (ie, increase in total body water).

    PubMed Central

    Peñarrocha, David; Bagán, José V.; Peñarrocha, Miguel

    2012-01-01

    Introduction. Trigeminal neuropathy is most often secondary to trauma. The present study explores the underlying causes and the factors that influence recovery. Material and methods. A retrospective case study was made involving 63 patients with trigeminal neuropathy of traumatologic origin, subjected to follow-up for at least 12 months. Results. Fifty-four percent of all cases were diagnosed after mandibular third molar surgery. In 37 and 19 patients the sensory defect was located in the territory innervated by the mental and lingual nerve, respectively. Pain was reported in 57% of the cases, and particularly among the older patients. Regarding patient disability, quality of life was not affected in three cases, while mild alterations were recorded in 25 subjects and severe alterations in 8. Partial or complete recovery was observed in 25 cases after 6 months, and in 32 after one year. There were few recoveries after this period of time. Recovery proved faster in the youngest patients, who moreover were the individuals with the least pain. Conclusion. Our patients with trigeminal neuropathy recovered particularly in the first 6 months and up to one year after injury. The older patients more often suffered pain associated to the sensory defect. On the other hand, their discomfort was more intense, and the patients with most pain and the poorest clinical scores also showed a comparatively poorer course. Key words:Post-traumatic trigeminal neuropathy. PMID:22143689

    2016-05-01

    Conclusions This study demonstrates an association between sialolithiasis and nephrolithiasis. The results call for more awareness of this association among physicians and patients with nephrolithiasis. Objective Very few empirical studies have been conducted to explore the potential association between sialolithiasis and nephrolithiasis. As such, the association between sialolithiasis and nephrolithiasis still remains unclear. This study aimed to explore the possible association between sialolithiasis and nephrolithiasis using a population-based dataset. Methods Using data from the Taiwan Longitudinal Health Insurance Database 2005, this case-control study identified 966 patients with sialolithiasis as cases and 2898 sex- and age-matched subjects without sialolithiasis as controls. Conditional logistic regressions were conducted to examine the association of sialolithiasis with previously diagnosed nephrolithiasis. Results Out of 3864 sampled patients, 165 (4.27%) had prior nephrolithiasis. Using Chi-square test, it was found that there was a significant difference in the prevalence of prior nephrolithiasis between the cases and controls (10.25% vs 2.28%, p < 0.001). Moreover, by conditional logistic regression analysis, the odds ratio of prior nephrolithiasis for cases was 4.74 (95% CI = 3.41-6.58, p < 0.001) when compared to controls after adjusting for monthly income, geographic location, urbanization level of residence, diabetes, hypertension, heart failure, chronic renal disease, and tobacco use.

  17. Innovation in energy systems: a case study of gasoline rationing

    SciTech Connect

    Sullivan, M.C.

    1981-01-01

    The purpose of the study is to develop a theoretical understanding of the implementation of new programs (innovations) by organizations, verify concepts with a case study of gasoline rationing, and apply knowledge gained to an analysis of the Standby Gasoline Rationing Plan. Major hypotheses of the study are: (1) Role specialization is required during the initial stage of implementation. (2) Decentralization is required during the initial stage of implementation. (3) Role specialization hinders implementation during the later stage. (4) Centralization is required during the later stage of implementation. The concept of technology delivery system is employed to demonstrate how organizational structure (degree of specialization centralization, etc.) is related to technological requirements and social need. The four major hypotheses were verified with the innovation theory as well as the case study of rationing. Application to the Standby Gasoline Rationing Plan leads to the conclusion that major problems would occur with plan implementation.

  18. Governance and management of a deepwater port: a case study

    SciTech Connect

    Olcott, E.S.

    1985-10-01

    A deepwater port is many things to many people. Clearly, the Port of Rotterdam, the largest port in the world, is a deepwater port with its 75 feet of water, more than $1.5 billion invested in facilities and its annual volume of more than 280 million metric tons of cargo in a broad commodity mix. Bantry Bay in Ireland, a major import petroleum and trans-shipment facility for Britain and the European continent, is a deepwater port. So also is the Louisiana Offshore Oil Port (LOOP), comprised of a single-point mooring buoy and sophisticated petroleum distribution system, located in deep water off the Gulf coast of the US. And so is the Port of Seattle a deepwater port, located in the natural deep water of Puget Sound. Deep drafts ports abound in Japan where as many as nine ports have been developed with water depths in excess of 55 feet. The multi-purpose port and industrial island located in Delaware Bay, the case study being scrutinized in this article would also be a deepwater port. The author takes no position in this article on the feasibility of the enterprise. A number of models or options are reviewed on how this project might be organized, managed, and governed if a decision were made to move forward with such an undertaking. 15 references, 2 figures.

    Kjuus, H; Lislerud, A; Lyngdal, P T; Omland, H; Stave, O; Langård, S

    1982-02-01

    The possible association between selected cancers and polluted work places has been studied in a hospital-based, case-control study. By dividing all jobs in the participants working career into "polluted" and "clean", a crude measure for the total industrial exposure a worker experiences throughout his life was established. Among 103 age-matched, case-control pairs the overall estimated relative risk (RR) for exposed subjects (greater than or equal to 10 years in a polluted work place) of developing cancer compared to nonexposed (less than 10 years in a polluted work place) was 1.1. The only subgroup where a significant difference was found between the cases and the controls was the lung cancer subgroup (RR = 4.0, p = 0.02, two-tailed). When the 30 lung cancer cases were compared to an alternative control group consisting of 60 subjects matched for age and smoking habits, an estimated RR of 4.5 was found. A moderate, but not significant association between lung cancer and definite asbestos exposure was also found (RR: 2.3). As most workers are exposed to a variety of industrial agents throughout their working careers, further development of methods for characterizing combined exposures are needed, both for retrospective and prospective purposes.

  20. Do studies of the nature of cases mislead about the reality of cases? A response to Pattison et al.

    PubMed Central

    Higgs, R

    1999-01-01

    This article questions whether many are misled by current case studies. Three broad types of style of case study are described. A stark style, based on medical case studies, a fictionalised style in reaction, and a personal statement made in discussion groups by an original protagonist. Only the second type fits Pattison's category. Language remains an important issue, but to be examined as the case is lived in discussion rather than as a potentially reductionist study of the case as text. PMID:10070639

  1. A case-control study of asthma and ovarian cancer.

    2010-01-01

    Epidemiologic studies have found inverse associations between allergy and the development of certain tumors. The authors sought to determine if there was an association between asthma and ovarian cancer. A case-control study was conducted using Florida hospital data (year 2001). Discharge diagnoses were coded using the ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification). Cases were 1,582 women whose principal discharge diagnosis was a malignant neoplasm of the ovary. Two control series were used: 4,744 women whose principal diagnosis was an upper limb bone fracture, and 21,830 women whose principal diagnosis was an acute myocardial infarction. Odds ratios (ORs) adjusted for age, race-ethnicity, Medicaid status, obesity, and smoking were calculated. Cases were 30% less likely than fracture control to be asthmatics (adjusted OR = 0.70, 95% confidence interval [CI]: 0.49-0.99, p = .04). Similarly, cases when compared to acute myocardial infarction controls were significantly less likely to have asthma (adjusted OR = 0.62, 95% CI: 0.45-0.87, p = .005). The results of this statewide exploratory study suggest that individuals with asthma may have a lower risk of developing ovarian cancer than nonasthmatics. PMID:20439229

    This case study is an example of applying narrative medicine as a useful tool for health professionals to manage an existential and complex scenario such as the suicide of a sibling. Some suicides are like baobab trees—these large and resilient trees grow deep roots for many years, only spreading their limbs above ground once they are firmly established. Like the baobab, when suicide or a suicide attempt occurs, suicidal ideations are well cultivated and have often already been repeatedly planted. Consequently, suicide is often difficult to prevent: once the death seed is planted, it is difficult to recreate life. Every year, more than 800,000 people die by suicide worldwide (1.4% of all deaths), which is approximately 1 person every 40 seconds. These unexpected deaths, predominantly occuring among young and middle-aged adults, have a continuing ripple effect and result in a huge economic, social, and psychological burden for individuals, families, communities, and countries. The complexity of suffering and pain experienced by suicidal individuals and their families, regardless of the success or failure of the suicidal act, is intensified by strong stigmas attached to traditional concepts of sin and eternal damnation. This unfortunate reality emerges in the narrative as a tragic family drama, which is permeated by deep feelings of helplessness. But suicide is preventable. Prevention requires 3 important factors: knowledge, public support, and creation of strategies to enact social change. Now is the time to act and make suicide prevention an imperative goal.

    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

    Albertazzi, Liliana; Poli, Roberto

    2014-01-01

    The paper presents color as a case study for the analysis of phenomena that pertain to several levels of reality and are typically framed by different sciences and disciplines. Color, in fact, is studied by physics, biology, phenomenology, and esthetics, among others. Our thesis is that color is a different entity for each level of reality, and that for this reason color generates different observables in the epistemologies of the different sciences. By analyzing color as a paradigmatic case of an entity naturally spreading over different levels of reality, the paper raises the question as to whether making explicit the usually implicit ontological assumptions embedded within the different observables exploited by the different sciences may eventually clarify some of the difficulties of developing a comprehensive theory of color.

    In this case study, a young women who has chronic verbal, emotional, and physical abuse and was exposed to repetitive adult acts of abuse as a child initially presented with Posttraumatic Stress Disorder (PTSD) marked by constriction and disconnection, which resulted in her feeling passive and tortured. As part of her occupational therapy intervention, based on the occupational adaptation, psychoanalytic, and recovery frames of reference, she was able to use her skills as a musician and lyricist to work through her trauma by performing heavy metal music. She used work to express emotions and tell and retell her story to audiences eager to hear her. Work helped her develop an identity that allowed her to be active in the world and reach out to others through her music. This case study focuses on the intervention - how music and occupation functioned as a foundation for relieving her PTSD. PMID:21248422

    2014-01-01

    This article presents a case study on the radicalization of Omar al-Hammami, aka Abu Mansoor al-Amriki, an American who joined al-Shabaab, a Somali terrorist group. There are a limited number of in-depth case studies that help to inform the fragmented discussions in the literature about the radicalization process of Islamic terrorists. Hammami received quite a bit of attention from the government and media due to his "homegrown" status, as well as his prolific use of social media to inform the world of his views and exploits. Hammami did not fully commit to the group, his sense of self-importance taking precedent over the norms of the group. He left al-Shabaab, was publicly critical of the group, and was ultimately killed by them. PMID:24604760

    1997-11-01

    The purpose of this case-referent study was to analyze the association between coxarthrosis and occupation. The study was performed in a Swedish agricultural county and comprised 269 cases of radiologically verified arthrosis of osteoarthritis (< 3 mm joint space) that were compared to 538 randomly selected controls in the same region, matched for age, sex, and place of residence. Farmers and agricultural workers showed an increased risk of coxarthrosis and the observed risk increased with increasing number of years of farming. Tractor driving and milking were associated with coxarthrosis, whereas no association with other types of machine work could be demonstrated. An association between coxarthrosis and heavy physical work before the age of 16 years was also observed. The results give only limited information on the external causes of coxarthrosis, however. More detailed studies of groups of individuals with coxarthrosis in order to obtain more information about contributing and underlying factors would therefore be valuable. PMID:9327073

    Objectives: To present 17 natal/neonatal teeth in 15 patients and describe their clinical characteristics, associated disorders, complications and treatment. Methods: A retrospective study of neonates who visited the Department of Pedodontics and Preventive Dentistry, College of Dental Sciences, Davangere, India, between 2003 and 2006 was carried out. It was a study of clinical data, such as the age and gender of the patients, the history and chief complaints of mothers, the clinical appearance and location of natal/neonatal teeth, and associated complications and treatments. Results: A total of 17 teeth (6 natal, 11 neonatal) were found in 15 patients. No significant gender predilection (8 male, 7 female) was found. Sixteen natal/neonatal teeth were placed in mandibular incisor area (10 on the right side and 6 on the left side) and one tooth in the maxillary incisor area. In 13 patients, the occurrence of natal/neonatal teeth was unilateral, and in 2 patients, it was bilateral. Three cases were associated with enamel hypoplasia, 3 cases with Riga-Fede disease, and 1 case with gingival hyperplasia. One case involved a patient with cleft lip and palate. Radiographic examination confirmed these teeth to be supernumerary, and all teeth exhibited hypermobility. Extraction had been done in all the cases. Eleven of the extracted teeth exhibited only rudimentary roots, and six teeth showed no roots. Conclusions: The occurrence of a natal/neonatal tooth is a rare phenomenon. When it occurs, the teeth have a variety of clinical characteristics and lead to different complications. Knowledge of the management of these structures is essential for the overall well being of a child. PMID:21494384

    Mixing is an important part of irreversible stratosphere troposphere exchange. Yet the mixing process is poorly understood. We present a case study of mixing in the vicinity of the subtropical jet, using airborne in situ and remote sensing data during SONEX mission. The case of intrusion of stratospheric air is identified using ozone profile curtains from DIAL LIDAR onboard DC-8. The thermal structure across the tropopause is mapped using temperature profiles from Microwave Temperature Profiler (MTP), together with the potential vorticity field based on the ECMWF data. Spatial extent of mixing between stratospheric and tropospheric air is examined using tracer relationships from in situ measurement onboard DC-8. Results show that mixing between stratospheric and tropospheric air involved air mass with ozone value up to ~400 ppbv. The case study also show that based on the tracer relationship alone, without the background information provided by the LIDAR data and MTP data, it is often difficult to conclude whether the observed mixing represent stratosphere to troposphere transport or troposphere to stratosphere transport. Results also show that using 2 PVU or 3.5 PVU contour as the tropopause in this case will likely underestimate the stratosphere to troposphere transport.

    2014-01-01

    Anorexia nervosa (AN) is considered a relatively “modern” disorder; however, a number of scholarly works have cited examples of voluntary self-starvation dating back to several centuries. In particular, there are many examples of female starvation for religious reasons during the medieval period, with many being elevated to sainthood. We present a case of an elderly woman with AN who began restricting her diet when she was 13-years old while studying to be a nun at a Catholic convent. She reports that, during the development of her disease, she had no mirrors and, rather than restricting her diet to be thin or attractive, she restricted her diet to be closer to God in hopes of becoming a Saint. This unique case presents an opportunity to deepen our understanding of AN and the cultural context that affects its development. PMID:25105049

    Shape is an inherent trait of a molecule that dictates how it interacts with other molecules, either in binding events or intermolecular reactions. Large-ring macrocyclic compounds in particular leverage their shape when they are selectively bound by biomolecules and also when they exhibit macrocyclic diastereoselectivity. Nonetheless, rules that link structural parameters to the conformation of a macrocycle are still rudimentary. Here we use a structural investigation of a family of [13]-macrodilactones as a case study to develop rules that can be applied generally to macrocycles of different sizes and with a variety of functionality. A characteristic "ribbon" shape is adopted by the [13]-macrodilactones in the absence of stereogenic centres, which exhibits planar chirality. When one stereogenic centre at key positions on the backbone is incorporated into the structure, the planar chirality is dictated by the configuration of the centre. In cases where two stereogenic centres are present, their relationships can either reinforce the characteristic ribbon shape or induce alternative shapes to be adopted. The rules established in the case study are then applied to the analysis of a structure of the natural product migrastatin. They lay the groundwork for the development of models to understand macrocycle-biomolecule interactions and for the preparation of macrocycles with designed properties and activities. PMID:27001347

    Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. PMID:26284573

    The decision tree transient stability method is revisited via a case study carried out on the French EHV power system. In short, the method consists of building off-line decision trees, able to subsequently assess the system transient behavior in terms of precontingency parameters (or attributes'') of it, likely to drive the stability phenomena. This case study aims at investigating practical feasibility aspects and features of the trees, at enhancing their reliability to the extent possible, and at generalizing them. Feasibility aspects encompass data base generation, candidate attributes, stability classes; tree features concern in particular complexity in terms of their size and interpretability capabilities, robustness with respect to both their building and use. Reliability is enhanced by defining and exploiting pragmatic quality measures. Generalization concerns multicontingency, instead of single-contingency trees. The results obtained show real promise for the method to meet practical needs of electric power utilities.

    This article will explore pediatric consent through the analysis of a clinical case study using the principles of biomedical ethics approach. Application of the principles of autonomy, nonmaleficence, beneficence, and justice will be dissected in order to attempt to establish resolution of the ethical dilemma. The main conflict in this case study deals with whether the wishes of an adolescent for end-of-life care should be followed or should the desire of his parents outweigh this request. In terminal cancer, the hope of early palliative care and dignity in dying serve as priorities in therapy. Application of the moral principles to both sides of the dilemma aided in providing an objective resolution to uphold pediatric consent. PMID:22753459

    Previous studies have shown that lung recruitment maneuvers are important means of treating ARDS. Although computed tomography (CT) scans and pressure-volume curves are the most common ways to evaluate lung recruitment, there are still many disadvantages. Not only do the scans have to take place in a CT room, but the patient is exposed to large doses of radiation through the multiple scans necessary to define the optimal PEEP. Pressure-volume curves require deep sedation and muscle relaxation. Thus, bedside lung ultrasound may be considered to be a safer and easier alternative to CT scans or pressure-volume curves. In our case, we evaluated the effectiveness of lung recruitment with a bedside ultrasound on a patient who was suffering from life-threatening hypoxemia. Bedside ultrasound is a faster and more convenient imaging method because it reduces the need for patient transport compared with CT scan and requires no muscle relaxation. This case supports that ultrasound may become an alternative imaging tool to guide and evaluate alveolar recruitment in patients with ARDS. Additionally, we have also included a brief review of lung recruitment evaluation by ultrasound to supplement this case study. PMID:25406343

    OBJECTIVES. This study tests the hypothesis that fluoride exposure in a nonoccupational setting is a risk factor for childhood osteosarcoma. METHODS. A population-based case-control study was conducted among residents of New York State, excluding New York City. Case subjects (n = 130) were diagnosed with osteosarcoma between 1978 and 1988, at age 24 years or younger. Control subjects were matched to case subjects on year of birth and sex. Exposure information was obtained by a telephone interview with the subject, parent, or both. RESULTS. Based on the parents' responses, total lifetime fluoride exposure was not significantly associated with osteosarcoma among all subjects combined or among females. However, a significant protective trend was observed among males. Protective trends were observed for fluoridated toothpaste, fluoride tablets, and dental fluoride treatments among all subjects and among males. Based on the subjects' responses, no significant associations between fluoride exposure and osteosarcoma were observed. CONCLUSIONS. Fluoride exposure does not increase the risk of osteosarcoma and may be protective in males. The protective effect may not be directly due to fluoride exposure but to other factors associated with good dental hygiene. There is also biologic plausibility for a protective effect. PMID:7503344

    The decision to design and build a new aircraft is preceded by years of research and study. Different disciplines work together throughout the lifecycle to ensure not only a complete functional definition of the product, but also a complete industrialization, a marketing plan, a maintenance plan, etc. This case study focuses on the conceptual design phase. During this phase, the design solutions that will meet the functional and industrial requirements are defined, i.e.: the basic requirements of industrialization. During this phase, several alternatives are studied, and the most attractive in terms of performance and cost requirements is selected. As a result of the study of these alternatives, it is possible to define an early conceptual design of the assembly line and its basic parameters. The plant needs, long cycle jigs & tools or industrial means and human resources with the necessary skills can be determined in advance.

    This case study describes the process of fusing the data from several wind tunnel experiments into a single coherent visualization. Each experiment was conducted independently and was designed to explore different flow features around airplane landing gear. In the past, it would have been very difficult to correlate results from the different experiments. However, with a single 3-D visualization representing the fusion of the three experiments, significant insight into the composite flowfield was observed that would have been extremely difficult to obtain by studying its component parts. The results are even more compelling when viewed in an immersive environment.

    Steady-state analysis of dynamical systems for biological networks gives rise to algebraic varieties in high-dimensional spaces whose study is of interest in their own right. We demonstrate this for the shuttle model of the Wnt signaling pathway. Here, the variety is described by a polynomial system in 19 unknowns and 36 parameters. It has degree 9 over the parameter space. This case study explores multistationarity, model comparison, dynamics within regions of the state space, identifiability, and parameter estimation, from a geometric point of view. We employ current methods from computational algebraic geometry, polyhedral geometry, and combinatorics. PMID:26645985

    This article examines the case of a Mexican American woman who was found not guilty by reason of insanity for infanticide, the murder of her young son. A detailed case history is presented with a focus on cultural issues as they affect this woman's family dynamics, assimilation and acculturation, emotionality, spirituality, and seeking of mental health treatment. In addition, a theoretical conceptualization is presented, identifying the psychodynamic operations that laid the foundation for the crime, including the normal process of identity development and the mitigating factors of gender, culture, and psychopathology. The study explores the important influences of culture in the commission of this crime as well as in subsequent treatment, highlighting the changes in society and mental health treatment that need to be made to reduce the incidence of such family violence.

    The most malignant form of all brain tumors is the supratentorial astrocytoma. Little is known about its etiology, but exogenous factors have been blamed. In this case-control study, 78 astrocytoma patients have been compared with 197 clinical and 92 population controls. An extensive questionnaire was used to gather information about occupational and residential environment exposure. Inquiries concerning groups of or individual chemicals elicited low rates of affirmative response, with negligible differences between cases and controls. However, the questions working at an airfield and living near a petrochemical plant indicated elevated risks in comparison with both control groups; so too did living near a municipal sewage treatment plant. These results focus attention on exposure to organic compounds and should be considered together with similar findings in current research. No other occupation, branch of industry, or vicinity questions showed differences between cases and controls, with the exception of living in the neighborhood of a paper mill or a saw mill, which gave moderately increased relative risks. A separate report gives the results from the nonoccupational part of the study.

    Background: Gastroschisis, a birth defect characterized by herniated fetal abdominal wall, occurs more commonly in infants born to teenage and young mothers. Ischemia of the vascular vitelline vessels is the likely mechanism of pathogenesis. Given that chronic stress and violence against women are risk factors for cardiovascular disease we explored whether these may represent risk factors for gastroschisis, when they occur during pregnancy. A case-control study was conducted, with 15 incident cases of children born with gastroschisis in the Region of Murcia, Spain, from December 2007 to June 2013. Forty concurrent controls were recruited at gestation weeks 20–24 or post-partum. All mothers of cases and controls completed a comprehensive, in-person, ‘green sheet’ questionnaire on environmental exposures. Results: Mothers of children with gastroschisis were younger, smoked more cigarettes per week relative to controls, were exposed to higher amounts of illegal drugs, and suffered from domestic violence more frequently than the controls. Multivariable logistic regression analysis highlights periconceptional ‘gender-related violence’ (OR: 16.6, 95% CI 2.7 to 101.7) and younger maternal age (OR 1.1, 95% CI 1.0–1.3). Conclusions: Violence against pregnant women is associated with birth defects, and should be studied in more depth as a cause-effect teratogenic. Psychosocial risk factors, including gender-based violence, are important for insuring the health and safety of the pregnant mother and the fetus. PMID:24142184

    In the area of fixed prosthodontics, implants have evolved to become the gold standard in terms of longevity and esthetic outcome (1). As in all of dentistry, careful diagnosis and treatment planning is a must to achieve an optimum result. When evaluating the recipient site, one must determine if any type of defect (hard or soft tissue) exists which would require augmentation. The existing occlusion must also be evaluated to ensure the dentist is aware of possible prosthetic complications. In straightforward cases, such as those without the need for augmentation, the conventional timeline requires a waiting period of 3 months following surgical placement to begin the restorative procedures. Factoring in the restorative time frame, the patient may wait up to approximately 4 months for the final implant prosthesis. Various advancements in dentistry are changing the way dentists approach implant dentistry--from diagnosis and treatment planning to final restorations. This article illustrates these advances through a case study. PMID:24937892

    Wolf-Hirschhorn syndrome is caused by a deletion of a segment on the short arm (p) of chromosome 4. The major features of this disorder include a characteristic facial appearance known as the "Greek helmet," delayed growth and development; prenatally and postnatally, intellectual disabilities, and seizures. To provide comprehensive and appropriate nursing and medical care to infants with Wolf-Hirschhorn syndrome, it is imperative to know and understand the disorder. A case study of a 36 weeks' gestational age white-Hispanic male infant with Wolf-Hirschhorn syndrome is presented with the purpose of increasing clinical knowledge and the implications for the clinical nurse and neonatal nurse practitioner.

    2000-09-01

    The aim of this study was to evaluate the histologic characteristics of hemangioblastoma (HB) and investigate the histogenesis of its stromal cells. Sixty-eight cases of hemangioblastoma were studied by light microscopy and thirty-three cases were examined by immunohistochemical stainning. Forty-eight of the 68 patients were males and 20 were females. The average age was 37. Fifty-two cases (76.6%) had been present for two months to one year before the diagnosis was made. Sixty cases (88.2%) arose in the cerebellum. Fifty cases (73.5%) appeared as cystic nodules. Histologically, the 68 cases of HB were further categorized into three subtypes: typical (30 cases), cellular (21 cases) and reticular (17 cases). In 33 cases, the stromal cell were positive for NSE, but negative for F-VIII, UEA-1, GFAP and EMA. In summary, there are three essential histologic categories of hemangioblastoma, and its stromal cells may well have the characters of neuroendocrine differentiation. PMID:12545840

    The purpose of this investigation was to explore students' epistemic beliefs and conceptual understanding of biotechnology. Epistemic beliefs can influence reasoning, how individuals evaluate information, and informed decision making abilities. These skills are important for an informed citizenry that will participate in debates regarding areas in science such as biotechnology. We report on an in-depth case study analysis of three undergraduate, non-science majors in a biotechnology course designed for non-biochemistry majors. We selected participants who performed above average and below average on the first in-class exam. Data from multiple sources—interviews, exams, and a concept instrument—were used to construct (a) individual profiles and (b) a cross-case analysis of our participants' conceptual development and epistemic beliefs from two different theoretical perspectives—Women's Ways of Knowing and the Reflective Judgment Model. Two independent trained researchers coded all case records independently for both theoretical perspectives, with resultant initial Cohen's kappa values above .715 (substantial agreement), and then reached consensus on the codes. Results indicate that a student with more sophisticated epistemology demonstrated greater conceptual understandings at the end of the course than a student with less sophisticated epistemology, even though the latter performed higher initially. Also a student with a less sophisticated epistemology and low initial conceptual performance does not demonstrate gains in their overall conceptual understanding. Results suggest the need for instructional interventions fostering epistemological development of learners in order to facilitate their conceptual growth.

    The requirements engineering (RE) processes have become a key to conceptualising corporate-wide integrated solutions based on packaged enterprise resource planning (ERP) software. The RE literature has mainly focused on procuring the most suitable ERP package. Little is known about how an organisation exploits the chosen ERP RE model to frame the business application development. This article reports an exploratory case study of a key tenet of ERP RE adoption, namely that aligning business applications to the packaged RE model leads to integral practices and economic development. The case study analysed a series interrelated pilot projects developed for a business division of a large IT manufacturing and service company, using Oracle's appl1ication implementation method (AIM). The study indicated that AIM RE improved team collaboration and project management experience, but needed to make hidden assumptions explicit to support data visibility and integrity. Our study can direct researchers towards rigorous empirical evaluations of ERP RE adoption, collect experiences and lessons learned for practitioners, and help generate more effective and mature processes when exploiting ERP RE methods.

    Background Concussion, its recognition, diagnosis, and treatment is a growing public health issue. Massage practitioners who specialize in rehabilitation deal with a variety of injury cases that involve concussion, including those incurred by falls, motor vehicle incidents, and sports injuries. Purpose This case study presents a unique massage therapy approach to concussion trauma treatment. Participant Male 23-year-old intramural soccer player diagnosed with postconcussion syndrome resulting from a fall. Intervention Assessment and treatment were completed in two sessions of 45 minutes spaced two days apart. Massage therapy techniques were applied to injury areas by a Licensed Massage Practitioner. Results Using the Balance Error Scoring System (BESS) and self-report, the outcome measures showed diminished concussion symptoms and regained ease in range of motion in the cervical area. Conclusion Positive results for this case highlight the potential importance of massage therapy work to reduce headache, dizziness, and nausea in concussion recovery. In the presence of such outcomes, massage therapy may also have a supportive role in a person’s return to function after concussion. PMID:26082825

    Historically, many healthcare information systems (HIS) have been designed around monolithic architectures that rely upon a single organization to provide most, if not all, of the system's business logic. Recent advances in distributed systems technology and healthcare standards make a component-based architecture feasible in building today's HIS. The First DataBank Drug Toolkit is used as a case study for the role of components in the design of a HIS. Several technical challenges associated with building truly plug and play components are discussed. PMID:10175372

    PubMed Central

    2013-01-01

    Background The implementation of unfolding scenario-based case studies in the didactic classroom is associated with learner-centered education. The utilization of learner-centered pedagogies, such as case studies, removes the focus from the instructor and instead places it on the student. Learner-centered pedagogies are believed to improve students’ levels of cognition. The purpose of this study was to examine how nurse educators are implementing the pedagogies of case studies in their undergraduate didactic courses. The goal was to examine, document, report, and, ultimately, implement the strategies. Methods Purposeful sampling was utilized in this qualitative, multisite-designed study. For each of the four participants, three separate site visits were completed. Observations and post-observational interviews took place at each site visit. Transcribed data from interviews, observations, and course documents were imported into the computer program Nvivo8. Repetitive comparative analysis was utilized to complete the data coding process. Results The guiding research question of this study sought to investigate the implementation strategies of case studies in didactic nursing courses. The implementation of case studies by the participants reflected two primary patterns: Formal Implementation (FI) and Informal Implementation (II) of case studies. The FI of case studies was further divided into two subcategories: Formal Implementation of case studies used Inside the Classroom setting (FIIC) and Formal Implementation of cases studies used Outside of the Classroom (FIOC). Conclusion Results of this investigation have led to an increased understanding of implementation strategies of unfolding scenario-based case studies in undergraduate nursing didactic courses. Data collected were rich in the description of specific methodologies for utilization of case studies and may serve as a resource for faculty in development of creative strategies to enhance the didactic

    Inherited thrombophilia is believed to be a multiple gene disease with more than one defect. We wanted to determine the association between single thrombophilic patterns and a variety of pregnancy diseases. 301 pregnant women were recruited for the present case-control study and were divided into two groups: A group (176 controls) and B group (125 cases). Patients belonging to the B group had one of the following: severe preeclampsia, HELLP syndrome, gestational hypertension, fetal growth restriction (FGR), intrauterine death, abruptio placentae, placenta previa, disseminated intravascular coagulopathy (DIC) and preterm labour. To detect MTHFR A1298C, MTHFR C677T, Factor V Leiden, PAI-1, Mutant Prothrombin G20210A, an inverse hybridization technology was used. Plasma homocysteine, Antithrombin III and protein levels S were determined. A modified functional activated protein C resistance was assayed. MTHFR C677T and hyperhomocysteinemia were more numerous than other thrombophilias. Deficiency in AT III was significantly linked with preeclampsia (Pearson Index and p value: 0.131 and 0.022, respectively) and disseminated intravascular coagulopathy (Pearson Index and p value: 0.138 and 0.016 respectively). Activated Protein C resistance was related to abruptio placentae (Pearson Index and p value: 0.159 and 0.005 respectively). Apart from the linkage between AT III deficiency and the occurrence of preeclampsia and disseminated intravascular coagulopathy, we obtained findings in contrast to some literature. In our case series, no association of preeclampsia with Factor V Leiden or with prothrombin gene mutation was found. PMID:23675040

    Little is known about oral clefts in developing countries. We aimed to identify micronutrient-related and environmental risk factors for oral clefts in Thailand. We tested hypotheses that maternal exposure during the periconceptional period to multivitamins or liver consumption would decrease cleft lip with or without cleft palate (CL ± P) risk and that menstrual regulation supplements would increase CL ± P risk. We conducted a multisite hospital-based case-control study in Thailand. We enrolled cases with CL ± P and 2 live births as controls at birth from the same hospital. Mothers completed a questionnaire. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Eighty-six cases and 172 controls were enrolled. Mothers who took a vitamin (adjusted OR, 0.39; 95% CI: 0.16, 0.94) or ate liver (adjusted OR, 0.26; 95% CI: 0.12, 0.57) were less likely than those who did not to have an affected child. Mothers who took a menstrual regulation supplement were more likely than mothers who did not to have an affected child. Findings did not differ for infants with a family history of other anomalies or with isolated CL ± P. If replicated, our finding that liver decreases CL ± P risk could offer a low-cost primary prevention strategy. PMID:24097855

    Marital separation and divorce are associated with increased risk for early death, and the magnitude of this association rivals that of many well-established public health factors. In the case of divorce, however, the mechanisms explaining precisely why and how some people are at risk for early death remain unclear. This paper reviews what is known about the association between divorce and risk for all-cause mortality, then discusses four emerging themes in this area of research: the biological intermediaries linking divorce to pathophysiology and disease onset, moving beyond the statistical mean, focusing research on the diathesis-stress model, and studying how opportunity foreclosures may place people on a trajectory toward poor distal health outcomes. These ideas are grounded in a set of public lay commentaries about the association between divorce and death; in this way, the paper seeks to integrate current research ideas with how the general public thinks about divorce and its correlates. Although this paper focuses on divorce, many of the emerging themes are applicable to the study of psychosocial stress and health more generally. Therefore, the study of divorce and death provides a good case study for health psychology and considers new questions that can be pursued in a variety of research areas. PMID:23284588

    Hand hygiene of healthcare workers is frequently poor despite the efforts of infection control teams to promote hand decontamination as the most important method to prevent transmission of hospital-acquired infections. In this case study, we describe how principles of societal marketing were applied to improve hand hygiene. Pre-marketing analysis of strengths, weaknesses, opportunities and threats to implementation; attention to product, price, promotion and placement; and post-marketing 'customer' surveys were the essential components of the marketing strategy and its implementation. Placement of an alcohol-based gel decontaminant (Spirigel) at the bedside of every patient was widely welcomed in the hospital, and has played a major role in improving hand hygiene of healthcare workers. In the twelve months following the implementation, the decontaminant was used at least 440,000 times. The cost of purchasing the decontaminant was approximately 5000 pounds sterling. Following the introduction of Spirigel, there was a consistent reduction in the proportion of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) in each of the quarters of 2000-2001 compared with 1999-2000. In the period 1999-2000, nearly 50% of the MRSA were hospital acquired compared with 39% in 2000-2001. Similarly, the average incidence of Clostridium difficile associated diarrhoea (CDAD) decreased in each of the quarters in 2000-2001 following the introduction of Spirigel. During this period, there was an average incidence of 9.5 cases of CDAD/1000 admissions compared with 11.5 cases of CDAD/1000 admissions in 1999-2000. This represents a 17.4% reduction in the incidence of CDAD. However, this reduction was not statistically significant (P=0.2). Our case study demonstrates that principles of societal marketing methods can be used effectively to promote and sustain hand hygiene in hospitals. Improvement in hand hygiene will lead to considerable reduction in hospital

    An 11 months 22 days old girl presented with a history of watery diarrhoea since birth, failure to thrive, and developmental delay. Her diagnosis was congenital chloride diarrhoea (CCD) with raised level of chloride (>90 mmol/L) in stool in the absence of cystic fibrosis. Management of CCD included replacement of NaCl, KCl, and correction of dehydration. Diarrhoea of the patient was resolved with Captopril, which was initially provided to the patient for managing heart failure. To our knowledge, this is the first reported case of CCD that shows the beneficial effect of Captopril. Therefore, we suggest that further study is warranted as to the potential for Captopril as additional option in the treatment for CCD. We present this case report with the informed consent of the patient's guardian. PMID:25995737

    Understanding faculty motivations for and barriers to change is an important component of facilitating instructional reform efforts to improve student learning. This case study describes the process of adoption of learner-centered instructional strategies by an astronomy faculty member, Ken, as viewed through the lens of conceptual change. Specifically, we applied the Cognitive Reconstruction of Knowledge Model (CRKM) to understand why Ken was willing to change his instructional strategies, what barriers to and supports for change existed, and how he and his students were impacted by this change. Ken's statements and actions represented characteristics consistent with the CRKM. Notably, dissatisfaction, considered the primary motivator in many conceptual change models, was not of high importance in this case. Upon implementing learner-centered strategies, Ken's students performed better on a measure of knowledge about stellar properties, which served to reinforce his motivation to continue with learner-centered methods.

    2005-12-01

    The study involves 204 cases of interpersonal assault reported to the police during a period of 1 year. The patterns of domestic violence and community violence involving friends, neighbors, and strangers are described. The most common type of violence reported to the police is community interpersonal violence in which victims are mostly females and perpetrators are mostly males and members of gangs. Cases of rape are reported, whereas spousal violence tends to be underreported. On the whole, female victims are more likely to be younger than their male counterparts, whereas the male perpetrators are more likely to be unemployed. Repeat assault is found in 43 instances. Possible psychological and sociological explanations are offered for violent gang activities. The need to sensitize the police to become more involved is emphasized. The author proposes suggestions that may help reduce the incidence of community violence. PMID:16246919

    An efficient, integrated health services delivery enterprise requires the ability to coordinate service delivery across the provider network and avoid duplication of services. It must be able to associate relevant clinical information with patients regardless of which facility delivered the services. There are significant challenges in collecting, organizing, and extracting value from data collected in the course of providing healthcare. This paper follows a large urban public healthcare enterprise in its attempts to address some of these challenges. Using a case-study methodology, the paper shows how information technology (IT) can help a healthcare organization derive improved information and generate knowledge from data stored in disjoint systems.

    Depression is a complex disorder with heterogeneous clinical anomalies whose neurobiological understanding still remains unclear. Medications have been implicated as potential causes of depression but for many of them, data are controversial. The present study aims to investigate association bet ween drugs and reports of depression. We used the case/non case method in the French pharmacovigilance database (FPVD) to identify drugs associated with depression. Cases were reports of depression in the FPVD between January 2007 and December 2011. Non cases were all other reports during the same period. Data were expressed as reporting odds ratio (ROR) with their 95% confidence interval. Of the 114,692 reports recorded in the FPVD during the studied period, we identified 474 cases of depression. For the majority of the patients, they were considered as "non serious" (56%) and evolution was favorable (64%). Significant RORs were found for antiepileptics (topiramate, levetiracetam), anti-infective and especially anti-retroviral drugs (efavirenz, emtricitabine, tenofovir, etravirine, raltegravir), interferons and other agents including isotretinoin, methylphenidate, sodium oxybate, varenicline, montelukast, flunarizine, adalimumab, anastrozole. Taking into account the limits of the methodology, the present study described associations with mainly expected drugs belonging to various therapeutic classes but it also found a signal with some anti-retrovirals. On the contrary, we did not find some assumed associations like cardiovascular medications, antimalarial. For most of the drugs, one or more mechanisms were found to explain these depressogenic effects on the basis of animal and human literature. Even if such associations need to be confirmed by further prospective studies, cautions are necessary for many drugs to early detect depressive symptoms. PMID:26056040

    The following case study examines the muscle and fat thickness of the trunk in a 25-year-old, former collegiate gymnast. Previous studies have quantified total and regional skeletal muscle mass using magnetic resonance imaging and muscle volume and distribution using ultrasound. However, to the best of our knowledge, the distribution and symmetry of skeletal muscle and subcutaneous adipose tissue (AT) of the anterior and posterior trunk have never been investigated. Ultrasound was used to identify skeletal muscle and AT thickness of 143 data points on the anterior portion of the trunk and 140 data points on the posterior portion of the trunk. Muscle thickness values in the anterior trunk ranged from 0.5 to 5.6 cm, and muscle thickness of the posterior trunk ranged from 0.6 to 6.6 cm. Total muscle volume of the trunk was 2935 and 4195 cm(3) for the anterior and posterior portions, respectively. The total predicted muscle mass in the anterior and posterior trunk was 7.4 kg. This case study begins to provide a picture of the distribution and symmetry of skeletal muscle and AT of the trunk. Future studies are necessary to confirm these findings and examine relationships among different populations. PMID:26550077

    OBJECTIVES: Associations between occupational exposures and the occurrence of cutaneous melanoma were examined as part of a large population based case-control study of 19 cancer sites. METHODS: Cases were men aged 35 to 70 years old, resident in Montreal, Canada, with a new histologically confirmed cutaneous melanoma (n = 103). There were two control groups, a randomly selected population control group (n = 533), and a cancer control group (n = 533) randomly selected from among subjects with other types of cancer in the large study. Odds ratios for the occurrence of melanoma were calculated for each exposure circumstance for which there were more than four exposed cases (85 substances, 13 occupations, and 20 industries) adjusting for age, ethnicity, and number of years of schooling. RESULTS: Significantly increased risk of melanoma was found for exposure to four substances (fabric dust, plastic dust, trichloroethylene, and a group containing paints used on surfaces other than metal and varnishes used on surfaces other than wood), three occupations (warehouse clerks, salesmen, and miners and quarrymen), and two industries (clothing and non-metallic mineral products). CONCLUSIONS: Most of the occupational circumstances examined were not associated with melanoma, nor is there any strong evidence from previous research that any of those are risk factors. For the few occupational circumstances which were associated in our data with melanoma, the statistical evidence was weak, and there is little or no supporting evidence in the scientific literature. On the whole, there is no persuasive evidence of occupational risk factors for melanoma, but the studies have been too small or have involved too much misclassification of exposure for this conclusion to be definitive.

    Ten cases of hydrops fetalis not associated with serologic incompatibility between mother and infant were studied by autopsy. Classic trisomy 21 was present in two, and in six others the postmortem examination revealed major congenital abnormalities (hydrometrocolpos-polydactyly syndrome, achondrogenesis type 2, congenital adenomatoid malformation of the lung, and aortic valvular dysplasia with left ventricular endocardial fibroelastosis). In two instances, anasarca was associated with a congenital tumor: a sacrococcygeal teratoma and an adrenal neuroblastoma. In six fetuses, prenatal diagnosis of hydrops fetalis or severe congenital malformations was established by ultrasonography. PMID:6897172

    As the healthcare system continues to reform, opportunities exist for infusion nurses to expand their practice into the business world. Traditionally, biomedical ethics have been used in nursing education as a framework for identifying and responding to ethical dilemmas. However, in the business world, professional ethics may be more subtle and insidious. A case study of ten infusion nurse consultants and their experiences with professional ethical issues is presented. Data were obtained using interviews, and content analysis revealed emergent themes of integrity and intuitive knowing with related categories. PMID:11847709

    Like their colleagues in fixed facilities, healthcare planners operating in a combat environment face the problem of transforming data into actionable information. Not all data is useful for decision-making and not all data comes neatly packaged. In this case study, the authors present an effort to collect and analyze data about forward surgical team utilization. The article shares the variety of data collected and the process of analysis, and concludes with a recommended process for data analysis in the field. PMID:26606410

    Some individuals face severe challenges with producing oral language (i.e., speech). In this article a case study of a child who experienced severe challenges with speech development is presented. Medical records, historical home videos, audio recordings, and photographs, in conjunction with an extensive journal maintained by the child’s mother provide the basis for this report, which profiles the child’s development from birth to age 8;0. This child’s development demonstrates the necessity of distinguishing between language—the mental representation of concepts and their relations—and speech—one means for communicating mental representations.

    Interpersonal Psychotherapy (IPT), a time-limited, evidence-based treatment, has shown efficacy in treating major depressive disorder and other psychiatric conditions. Interpersonal Psychotherapy focuses on the patient’s current life events and social and interpersonal functioning for understanding and treating symptoms. This case report demonstrates the novel use of IPT as treatment for posttraumatic stress disorder (PTSD). Preliminary evidence suggests IPT may relieve PTSD symptoms without focusing on exposure to trauma reminders. Thus IPT may offer an alternative for patients who refuse (or do not respond to) exposure-based approaches. Interpersonal Psychotherapy focuses on two problem areas that specifically affect patients with PTSD: interpersonal difficulties and affect dysregulation. This case report describes a pilot participant from a study comparing 14 weekly sessions of IPT to treatment with two other psychotherapies. We describe the session-by-session IPT protocol, illustrating how to formulate the case, help the patient identify and address problematic affects and interpersonal functioning, and to monitor treatment response.

    Background: Increased workload, case complexity, financial constraints, and staffing shortages justify wider implementations of digital pathology. One of its main advantages is distance reporting. Aim: A feasibility study was conducted at our institution in order to achieve comprehensive pathology services available by distance. Methods: One senior pathologist reported 950 cases (3,650 slides) by distance during 19 weeks. Slides were scanned by ScanScope AT Turbo (Aperio) and digital images accessed through SymPathy (Tieto) on a 14” laptop. Mobile phone, mobile broadband, broadband over Wi-Fi and broadband were used for internet connections along with a virtual private network technology (VPN). Lync (Microsoft) was tested for one case consultation and resident's teaching session. Larger displays were accessed when available. Effects of ergonomics and working flexibility on the user experience were observed. Details on network speed, frequency of technical issues, data usage, scanning, and turnaround, were collected and evaluated. Turnaround was compared to in-office microscopic reporting, measured from the registration to sign off. Results: Network speeds varied 1–80 Mbps (median download speed 8–65 Mbps). 20 Mbps were satisfactory for the instant upload of digital images. VPN, image viewer, and laptop failed on two occasions each. An estimated data usage per digital image was 10 MB (1–50 MB). Two cases (15 slides) were deferred to microscopic slides (0.21/0.41%) due to scanty material and suboptimal slide quality. Additional nine cases (15 slides) needed to be rescanned for various reasons (0.95/0.41%). Average turnaround was shorter, and the percentage of cases reported up to 3 days higher (3.13 days/72.25%) comparing with in-office microscopic reporting (3.90 days/40.56%). Larger displays improved the most user experience at magnifications over ×20. Conclusions: Existing IT solutions at our institution allow efficient and reliable distance reporting for
