    Harris, Mary Sadama

    This research sought to determine whether and how current local and national curricular mandates affect the science instruction of two exemplary Alabama elementary teachers. The study provides a description of the contextual backdrop of elementary teaching in Alabama and the curricular mandates resulting from federal legislation entitled The No Child Left Behind Act of 2001 that have been enacted across the state of Alabama. This study centers on the evolution of reform initiatives that impact the teaching of science in elementary schools. These reforms focus on student achievement, teacher accountability, subject matter testing, and federal legislation. The emphasis on accountability has created situations where teachers are, in any given year, faced with multiple program innovations focused on subject matter tested leaving other subjects areas such as science excluded from the curricula. Reform initiatives influential to this research were the Alabama Reading Initiative and Alabama's State Department of Education's mandated testing and progress monitoring of the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and how these reforms impact the elementary day and science instruction. The purpose of this research, which utilized a qualitative multiple case study design, was to understand how exemplary elementary science teachers in Alabama teach science given the curricular mandates that marginalize science instructional time. The central phenomenon centered on the curricular adaptations and negotiations teachers made in order to teach science. Data collected included classroom observations, semi-structured interviews, and artifacts. An inductive, interpretative approach to data analysis was used to allow for exploration of the sociocultural and sociopolitical influences on science teaching of these exemplary elementary teachers. Findings were constructed as narrative portraitures of each teacher and their science teaching bounded within their unique

  2. Teachers developing exemplary inquiry practices: Three longitudinal case studies

    Sweetman, Sara Berry

    If students are to be successful in the ever-changing scientific world they need to be taught how to think critically, to manipulate materials, and to gather evidence to build knowledge. Most teachers fall short in providing students the inquiry instruction described in the Next Generation Science Frameworks (National Research Council, 2011). This study examined three elementary science teachers' processes as they developed inquiry practices over time. The Electronic Quality of Inquiry Protocol (EQUIP) was used to gather quantitative and qualitative evidence of the teachers' inquiry practices in terms of four factors, Curriculum, Instruction, Discourse, and Assessment. A chronological analysis was used to examine the teachers' professional development and curriculum experiences in relation to their teaching practices. The results showed that all three teachers did change their practice, although the changes varied among cases. For each case, multiple factors influenced the teacher's development. There was a strong positive correlation between the quality of the teachers' inquiry practices and the time spent in curriculum-contextualized professional development. This research indicates that when teachers are supported with curriculum and professional development over extended periods, they develop exemplary inquiry practices. Three recommendations are provided for those interested in implementing science education reform.

  3. A case study of two exemplary biology teachers

    Treagust, David F.

    Research has indicated that most science classrooms are not intellectually demanding and place little emphasis on small group discussions and laboratory activities. However, successful science programs and competent science teaching that can provide models for other science teachers do exist. This study sought to document the teaching practices of two exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Both teachers had a thorough and comprehensive knowledge of the content they were to teach and had a range of teaching strategies that could be used without a great deal of thought. Their expectations for student performance were high, consistent, and firm. Students were expected to complete a high level of academic work in discussions, in problem work, and in laboratory activities, and were encouraged to take responsibility for their own learning. A distinctive feature of these biology classes was the high level of managerial efficiency, where lessons were busy occasions for both teacher and students; students had little opportunity for off-task behavior. Both teachers actively monitored the behavior of both high- and low-ability students by moving around the room and speaking with individuals, while still maintaining control of the entire class. By manipulating questioning and the social environment, both teachers encouraged students to engage in work, gave effective praise to the whole class and to individuals, encouraged student input by referring to it, helped students to effectively use their time, and gave marks for completion of set work. Compared to research with less-successful teachers, these teaching behaviors contributed to exemplary practice.

    To examine the exemplary practice of nurse consultants (NCs) and derive a model to illustrate the highest level of advanced nursing practice. A descriptive study was conducted to examine the practice and outcomes of seven NC roles in varied clinical specialties in Hong Kong. Exemplary practice was examined in relation to competencies for advanced practice nursing in Hong Kong and the United Kingdom. Data about NC characteristics and their practices were collected using a structured questionnaire and analyzed using descriptive statistics. Health service documents and clinical notes were analyzed using the framework approach. All NCs demonstrated the competence expected of an advanced practice nurse with impacts on patients, nursing profession, and the organization as identified in the advanced nursing practice framework in Hong Kong. NCs also performed at the highest level of practice delineated by Skills for Health in the United Kingdom. They were involved in diagnostic and therapeutic practice, and identified patient satisfaction and symptom management as key outcomes. This study provides new insight into levels of advanced practice and illustrates the exemplary work of NCs to demonstrate how they have developed and shaped services to bring about positive patient and organizational outcomes. Career laddering that places NCs at the highest level of advanced practice is important for making the best use of nursing expertise to achieve optimal patient and organizational outcomes. This study addresses a knowledge gap to enrich our current understanding of the impact of advanced practice nursing roles by linking NC role practices and competencies to key outcomes. © 2017 Sigma Theta Tau International.

    Clinician educators face numerous obstacles to their joint mission of facilitating high-quality learning while also delivering patient-centered care. Such challenges necessitate increased attention to the work of exemplary clinician educators, their respective teaching approaches, and the experiences of their learners. To describe techniques and behaviors utilized by clinician educators to facilitate excellent teaching during inpatient general medicine rounds. An exploratory qualitative study of inpatient teaching conducted from 2014 to 2015. Inpatient general medicine wards in 11 US hospitals, including university-affiliated hospitals and Veterans Affairs medical centers. Participants included 12 exemplary clinician educators, 57 of their current learners, and 26 of their former learners. In-depth, semi-structured interviews of exemplary clinician educators, focus group discussions with their current and former learners, and direct observations of clinical teaching during inpatient rounds. Interview data, focus group data, and observational field notes were coded and categorized into broad, overlapping themes. Each theme elucidated a series of actions, behaviors, and approaches that exemplary clinician educators consistently demonstrated during inpatient rounds: (1) they fostered positive relationships with all team members by building rapport, which in turn created a safe learning environment; (2) they facilitated patient-centered teaching points, modeled excellent clinical exam and communication techniques, and treated patients as partners in their care; and (3) they engaged in coaching and collaboration through facilitation of discussion, effective questioning strategies, and differentiation of learning among team members with varied experience levels. This study identified consistent techniques and behaviors of excellent teaching during inpatient general medicine rounds. © 2017 Society of Hospital Medicine

  16. Multiparametric approach for an exemplary study of laser printer emissions.

    The aim of this work was the study, by a multiparametric approach, of emissions from a laser printer in an experimental box-chamber, with particular attention to nanoparticles release. The experimental design included number concentration measurements by Fast Mobility Particle Sizer (FMPS) and chemical characterizations (elements) of size segregated samples collected by Nanomoudi cascade impactor. Volatile Organic Compounds (VOCs) were also sampled by charcoal sorbent tubes by personal sampling pumps. Monitoring of ozone, total volatile organic compounds concentrations and of temperature and humidity values inside the experimental box during the printing processes were also performed by automatic analyzers. The performed monitoring allowed to evidence different ways for particles emissions by laser printers, in particular showing that nanoparticles, characterised by high concentrations of Ba, Zn, B, K, Sr and Na, are set free at the beginning of the printing process. This emission seems to be directly ascribable to the use of toner powder, as all these elements are present in it. The emission of larger particles (ca. 100-320 nm) was observed in subsequent phases of the print process, probably due to the condensation of vapours released during the progressive heating of the fuser roller. This contribution was proved by both the FMPS measurements and the cascade impactor results. Also, a low emission of particles in higher size ranges was evidenced, mainly due to paper related particles. A very high concentration of VOCs was detected inside the chamber and the chemical speciation shows that the major contribution is associated to toner components, even if some species are released from other printer components. Although the formation of secondary species by reaction of VOCs with ozone cannot be excluded, these species were present inside the chamber at concentrations lower than the detection limit.

  17. An exemplary case of a bromine explosion event linked to cyclone development in the Arctic

    Directory of Open Access Journals (Sweden)

    A.-M. Blechschmidt

    2016-02-01

    Full Text Available Intense, cyclone-like shaped plumes of tropospheric bromine monoxide (BrO are regularly observed by GOME-2 on board the MetOp-A satellite over Arctic sea ice in polar spring. These plumes are often transported by high-latitude cyclones, sometimes over several days despite the short atmospheric lifetime of BrO. However, only few studies have focused on the role of polar weather systems in the development, duration and transport of tropospheric BrO plumes during bromine explosion events. The latter are caused by an autocatalytic chemical chain reaction associated with tropospheric ozone depletion and initiated by the release of bromine from cold brine-covered ice or snow to the atmosphere. In this manuscript, a case study investigating a comma-shaped BrO plume which developed over the Beaufort Sea and was observed by GOME-2 for several days is presented. By making combined use of satellite data and numerical models, it is shown that the occurrence of the plume was closely linked to frontal lifting in a polar cyclone and that it most likely resided in the lowest 3 km of the troposphere. In contrast to previous case studies, we demonstrate that the dry conveyor belt, a potentially bromine-rich stratospheric air stream which can complicate interpretation of satellite retrieved tropospheric BrO, is spatially separated from the observed BrO plume. It is concluded that weather conditions associated with the polar cyclone favoured the bromine activation cycle and blowing snow production, which may have acted as a bromine source during the bromine explosion event.

    This paper addresses the need for a paradigm shift from post-diagnosis tertiary care towards maintenance and promotion of health across the lifespan, for healthcare in general and in occupational healthcare specifically. It is based on the assumption that the realization of this paradigm shift may be facilitated by teaching (future) occupational health professionals to use the International Classification of Functioning, Disability and Health (ICF). Describing the development of a an ICF based occupational health curriculum. Grafting a training trajectory in the ICF for educating the biopsychosocial health paradigm, onto a training trajectory in the Critical Appraisal of a Topic (CAT), a method for teaching evidence based practice skills. The development process of the training trajectories in the master program Work, Health, and Career at Maastricht University is described as an example of an intervention for shifting the paradigm in healthcare curricula. The expected results are a shift from the biomedical towards the biopsychosocial paradigm, a reductionist approach towards a more holistic view on cases, a reactive way of working towards a more proactive work style, and from using a merely quantifiable evidence base towards using a broad evidence base. Incorporating the biopsychosocial paradigm into the assessment and scientific reasoning skills of students is not only valuable in occupational healthcare but might be a valuable approach for all disciplines in healthcare for which contextual factors are important e.g. rehabilitation, psychiatry and nutritional science.

  1. Exemplary Design Practice

    DEFF Research Database (Denmark)

    Jørgensen, Niels

    , including: If design knowing is bound to a given practical design context, how is it possible to generalize such knowing, as presumably required by an exemplary learning approach? To explore these questions, an account is given of the theories of exemplary learning proposed by Martin Wagenschein and Oskar...... Negt and the theories of design proposed by Herbert Simon and Schön. Simon's proposal of a generic science of design aligns well with Wagenschein's view of exemplary learning as a universal didactic approach. Therefore, in a sense, Simon's view is the most consistent with an exemplary learning approach......The didactic principle of exemplary learning may be defined briefly as 'learning by example'. In design education, working with a practical example is particularly appropriate, because design by definition is about creating a solution to a practical problem. Indeed, some design theorists claim...

  3. Exemplary Goods: Exemplars as Judgment Devices

    Directory of Open Access Journals (Sweden)

    Erwin Dekker

    2016-12-01

    Full Text Available In this article the notion of exemplars is developed to study valuation processes. It argues that exemplary goods are an important "judgment device" on markets of singular goods, which has so far been ignored in the literature. The article draws on Hannah Arendt's theory of exemplars, as well as literature from the philosophy of science and psychology to construct the new concept. Exemplars are particular goods that become focal points in markets that facilitate the mutual coordination of consumers and producers. From these exemplars norms of quality emerge which are otherwise hard or impossible to explicate. These exemplars and the norms of quality which emerge from them help shape the expectations of both producers and consumers with regard to new goods that are introduced to the market. Two illustrative cases, on classic literature and hip-hop music, are presented to demonstrate the relevance of the concept.

  10. Why does the Conductivity of a Nickel Catalyst Increase during Sulfidation? An Exemplary Study Using an In Operando Sensor Device.

    Science.gov (United States)

    Fremerey, Peter; Jess, Andreas; Moos, Ralf

    2015-10-23

    In order to study the sulfidation of a catalyst fixed bed, an in operando single pellet sensor was designed. A catalyst pellet from the fixed bed was electrically contacted and its electrical response was correlated with the catalyst behavior. For the sulfidation tests, a nickel catalyst was used and was sulfidized with H₂S. This catalyst had a very low conductivity in the reduced state. During sulfidation, the conductivity of the catalyst increased by decades. A reaction from nickel to nickel sulfide occurred. This conductivity increase by decades during sulfidation had not been expected since both nickel and nickel sulfides behave metallic. Only by assuming a percolation phenomenon that originates from a volume increase of the nickel contacts when reacting to nickel sulfides, this effect can be explained. This assumption was supported by sulfidation tests with differently nickel loaded catalysts and it was quantitatively estimated by a general effective media theory. The single pellet sensor device for in operando investigation of sulfidation can be considered as a valuable tool to get further insights into catalysts under reaction conditions.

    Full Text Available Exemplary Online Educators: Creating a Community of Inquiry Associate Professor Beth PERRY RN, PhD Centre for Nursing and Health Studies,Athabasca University - CANADA Associate Professor Margaret EDWARDS RN, PhDCentre for Nursing and Health Studies,Athabasca University - CANADA ABSTRACT As more university courses are offered online educators have much to learn regarding how to use this technology to facilitate effective learning. Some educators have mastered online teaching and are regarded by their students as highly effective. Researchers in this study consulted graduate students who had completed their degrees by online distance learning and asked them describe what they found made certain professors exemplary. Findings reveal that highly effective online instructors challenge and affirm learners. As well, the exemplary online educators establish a clear presence in the virtual classroom and are regarded by students as persons of influence. When the “Community of Inquiry” ( Garrison, Anderson, & Archer, n.d. model is used to situate the findings, elements of social, cognitive and teaching presence are evident in the approaches used by exemplary online educators. These study results have implications for the recruitment and selection of new faculty members and for the ongoing coaching and development of current faculty with the overall goal of enhanced quality of online education.

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

  5. Characteristics of Exemplary Science, Technology, Engineering, and Math (STEM)-Related Experiential Learning Opportunities

    Science.gov (United States)

    Simmons, Jamie Munn

    Experiential opportunities at the secondary level give students the "intimate and necessary relation between the processes of actual experience and education" (Dewey, 1938, p. 19- 20). Career and Technical Education classes (CTE) and co-curricular experiences, one type of experiential learning, underpin and cultivate student curiosity and often channel interests into STEM-related post-secondary disciplines and career choices. There is little existent research on the characteristics of exemplary experiential learning opportunities and the impact on stakeholders. This study is intended to identify the qualities and characteristics of an exemplary secondary experience through the lived experiences of the stakeholders; students, STEM-related teachers, and CTE/STEM Administrators. A qualitative research design was used to examine characteristics and implications for students of four STEM-related programs throughout Virginia. Conclusions from the study include fundamental principles for providing exemplary experiential STEM-related learning opportunities. These principles include: providing hands-on, real world learning opportunities for students, providing learning opportunities that will enhance student ownership in their learning, providing unique and comprehensive career exploration opportunities for students, providing a schedule for teachers that will give them time to plan, deliver, and manage exemplary experiential learning opportunities, providing continual teacher and administrator in-service training relative to planning and implementing exemplary experiential learning opportunities, investing appropriate funds for providing exemplary experiential learning opportunities. Establishing and maintaining active partnerships with business/industry and colleges/universities, and maintaining active advisory communities, providing appropriate staff to support the provision of exemplary experiential learning opportunities is needed.

  6. Factors influencing exemplary science teachers' levels of computer use

    Science.gov (United States)

    Hakverdi, Meral

    This study examines exemplary science teachers' use of technology in science instruction, factors influencing their level of computer use, their level of knowledge/skills in using specific computer applications for science instruction, their use of computer-related applications/tools during their instruction, and their students' use of computer applications/tools in or for their science class. After a relevant review of the literature certain variables were selected for analysis. These variables included personal self-efficacy in teaching with computers, outcome expectancy, pupil-control ideology, level of computer use, age, gender, teaching experience, personal computer use, professional computer use and science teachers' level of knowledge/skills in using specific computer applications for science instruction. The sample for this study includes middle and high school science teachers who received the Presidential Award for Excellence in Science Teaching Award (sponsored by the White House and the National Science Foundation) between the years 1997 and 2003 from all 50 states and U.S. territories. Award-winning science teachers were contacted about the survey via e-mail or letter with an enclosed return envelope. Of the 334 award-winning science teachers, usable responses were received from 92 science teachers, which made a response rate of 27.5%. Analysis of the survey responses indicated that exemplary science teachers have a variety of knowledge/skills in using computer related applications/tools. The most commonly used computer applications/tools are information retrieval via the Internet, presentation tools, online communication, digital cameras, and data collection probes. Results of the study revealed that students' use of technology in their science classroom is highly correlated with the frequency of their science teachers' use of computer applications/tools. The results of the multiple regression analysis revealed that personal self-efficacy related to

  7. Discouraged by Peer Excellence: Exposure to Exemplary Peer Performance Causes Quitting.

    Rogers, Todd; Feller, Avi

    2016-03-01

    People are exposed to exemplary peer performances often (and sometimes by design in interventions). In two studies, we showed that exposure to exemplary peer performances can undermine motivation and success by causing people to perceive that they cannot attain their peers' high levels of performance. It also causes de-identification with the relevant domain. We examined such discouragement by peer excellence by exploiting the incidental exposure to peers' abilities that occurs when students are asked to assess each other's work. Study 1 was a natural experiment in a massive open online course that employed peer assessment (N = 5,740). Exposure to exemplary peer performances caused a large proportion of students to quit the course. Study 2 explored underlying psychological mechanisms in an online replication (N = 361). Discouragement by peer excellence has theoretical implications for work on social judgment, social comparison, and reference bias and has practical implications for interventions that induce social comparisons. © The Author(s) 2016.

  8. Promoting the interest of African American teenage girls in science: What can we learn from an exemplary African American science teacher?

    Science.gov (United States)

    McMath, Cynthia Stewart

    This study focused on science teaching that promoted the interest of African American teenage girls in the science classroom of an exemplary African American science teacher. It focused on, observed and examined the planning, teaching and learning strategies used by the science teacher. It also described what the science teacher experienced during her high school years, during college, during her teaching career. The case study approach/method was used for this research to capture the description and examination of the practices of the science teacher. This research described how an African American female science teacher serves as a role model and influence a number of African Americans students, especially girls, who experience careers in science. During the interviews and observations the researcher used a system of record keeping for the study to include note taking, audio taping and pictures. It is evident in the findings that the teacher in this study had qualities of an exemplary teacher according to the research. It is further evident that the teacher served as a role model for her students. The results indicated that the exemplary African America science teacher was motivated by her former African American science teacher that served as a role model. The results in this study implied that the lack of the presence of more exemplary African American science teachers has an impact on the level of interest that African American students have in science. Further, it is implied that there is a great need for more practical research that may lead to closing the gap of missing African American science teachers.

    The commercial availability of automated inspection systems for optical surfaces specified according to ISO 10110-7 promises unsupervised and automated quality control with reproducible results. In this study, the classification results of the ARGOS inspection system are compared to the decisions by well-trained inspectors based on manual-visual inspection. Both are found to agree in 93.6% of the studied cases. Exemplary cases with differing results are studied, and shown to be partly caused by shortcomings of the ISO 10110-7 standard, which was written for the industry standard manual-visual inspection. Applying it to high resolution images of the whole surface of objective machine vision systems brings with it a few challenges which are discussed.

  14. Exemplary Amateurism: Thoughts on DIY Urbanism

    Directory of Open Access Journals (Sweden)

    Ann Deslandes

    2013-02-01

    Full Text Available Do-It-Yourself (DIY urbanism has become increasingly recognised as a non-professional and non-technocratic practice of urban alteration and community building. Already thus marked as ‘amateur’ in the contemporary sense (where the lines between amateur, professional, producer and consumer are significantly blurred, two of its key features are support for ‘proam’ cultural production and the ‘meanwhile’ use of commercial buildings. Within this, DIY urbanism is an important reference to economic and spatial scarcity in the Australian, English and North American cities where it has manifested as a discourse. The reference is particularly evident in the proximity to marginal urban space that participants in DIY urbanism share with other potential users of that space, which includes people experiencing primary homelessness. It is through this proximity that DIY urbanism works as a kind of ‘exemplary amateurism’. DIY urbanism demonstrates spatial scarcity in the city — a phenomenon in which amateur labour, 'meanwhile' use of buildings and homelessness are implicated.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    Houchens, Nathan; Harrod, Molly; Fowler, Karen E; Moody, Stephanie; Saint, Sanjay

    2017-09-01

    Clinical reasoning is a crucial component of training in health professions. These cognitive skills are necessary to provide quality care and avoid diagnostic error. Much previous literature has focused on teaching clinical reasoning in nonclinical environments and does not include learner reflections. The authors sought to explore, through multiple perspectives including learners, techniques used by exemplary inpatient clinician-educators for explicitly cultivating clinical reasoning. The authors conducted (2014-2015) a multisite, exploratory qualitative study examining how excellent clinician-educators foster clinical reasoning during general medicine rounds. This was accomplished through interviews of educators, focus group discussions with learners, and direct observations of clinical teaching. The authors reviewed field notes and transcripts using techniques of thematic analysis. Twelve clinician-educators, 57 current learners, and 26 former learners participated in observations and interviews. The techniques and behaviors of educators were categorized into 4 themes, including 1) emphasizing organization and prioritization, 2) accessing prior knowledge, 3) thinking aloud, and 4) analyzing the literature. The findings of this comprehensive study both confirm strategies found in previous literature and provide novel approaches. This is the first study to incorporate the perspectives of learners. Educators' techniques and behaviors, identified through direct observation and supported by reflections from the entire team, can inform best practices for the teaching of clinical reasoning.

    2018-04-01

    Full Text Available This paper describes a corpus of about 3,000 English literary texts with about 250 million words extracted from the Gutenberg project that span a range of genres from both fiction and non-fiction written by more than 130 authors (e.g., Darwin, Dickens, Shakespeare. Quantitative narrative analysis (QNA is used to explore a cleaned subcorpus, the Gutenberg English Poetry Corpus (GEPC, which comprises over 100 poetic texts with around two million words from about 50 authors (e.g., Keats, Joyce, Wordsworth. Some exemplary QNA studies show author similarities based on latent semantic analysis, significant topics for each author or various text-analytic metrics for George Eliot’s poem “How Lisa Loved the King” and James Joyce’s “Chamber Music,” concerning, e.g., lexical diversity or sentiment analysis. The GEPC is particularly suited for research in Digital Humanities, Computational Stylistics, or Neurocognitive Poetics, e.g., as training and test corpus for stimulus development and control in empirical studies.

  1. The Design of Effective ICT-Supported Learning Activities: Exemplary Models, Changing Requirements, and New Possibilities

    Directory of Open Access Journals (Sweden)

    Cameron Richards

    2005-01-01

    Full Text Available Despite the imperatives of policy and rhetoric about their integration in formal education, Information and Communication Technologies (ICTs are often used as an "add-on" in many classrooms and in many lesson plans. Nevertheless, many teachers find that interesting and well-planned tasks, projects, and resources provide a key to harnessing the educational potential of digital resources, Internet communications and interactive multimedia to engage the interest, interaction, and knowledge construction of young learners. To the extent that such approaches go beyond and transform traditional "transmission" models of teaching and formal lesson planning, this paper investigates the changing requirements and new possibilities represented by the challenge of integrating ICTs in education in a way which at the same time connects more effectively with both the specific contents of the curriculum and the various stages and elements of the learning process. Case studies from teacher education foundation courses provide an exemplary focus of inquiry in order to better link relevant new theories or models of learning with practice, to build upon related learner-centered strategies for integrating ICT resources and tools, and to incorporate interdependent functions of learning as information access, communication, and applied interactions. As one possible strategy in this direction, the concept of an "ICT-supported learning activity" suggests the need for teachers to approach this increasing challenge more as "designers" of effective and integrated learning rather than mere "transmitters" of skills or information through an add-on use of ICTs.

    2017-03-01

    The level of convergence between a rodent, the South American lowland paca Cuniculus paca, and a ruminant, the African water chevrotain Hyemoschus aquaticus, is analysed using 231 characteristics belonging to different biological sectors. A convergence index is established based on the degree of rarity of each characteristic in each species compared to other members of its zoological group. Although the divergent characteristics are as numerous as the convergent ones, the two species are globally similar. Convergent characteristics occur in all biological categories, but their rate varies a great deal among them. From internal anatomy and osteology, through behaviour and ecology to the external appearance of the body, convergent characteristics are all the more frequent since the biological category is directly implicated in the adaptation of animals to their external environment (lowland rainforest). However, only the individuals' characteristics are concerned and not those of their population or social organisation. This could be due to differences between the communities of terrestrial mammals to which they belong. Copyright © 2017 Académie des sciences. Published by Elsevier Masson SAS. All rights reserved.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

    International Nuclear Information System (INIS)

    Petterson, J.S.

    1988-06-01

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

    Jenkin, Gabrielle; Signal, Louise; Thomson, George

    2012-08-01

    In the context of the global obesity epidemic, national nutrition policies have come under scrutiny. The present paper examines whose interests - industry or public health - are served by these policies and why. Using an exemplary case study of submissions to an inquiry into obesity, the research compared the positions of industry and public health groups with that taken by government. We assessed whether the interests were given equal consideration (a pluralist model of influence) or whether the interests of one group were favoured over the other (a neo-pluralist model). 2006 New Zealand Inquiry into Obesity. Food and advertising industry and public health submitters. The Government's position was largely aligned with industry interests in three of four policy domains: the national obesity strategy; food industry policy; and advertising and marketing policies. The exception to this was nutrition policy in schools, where the Government's position was aligned with public health interests. These findings support the neo-pluralist model of interest group influence. The dominance of the food industry in national nutrition policy needs to be addressed. It is in the interests of the public, industry and the state that government regulates the food and advertising industries and limits the involvement of industry in policy making. Failure to do so will be costly for individuals, in terms of poor health and earlier death, costly to governments in terms of the associated health costs, and costly to both the government and industry due to losses in human productivity.

    Syncope, or the sudden loss of consciousness, is a common presenting symptom for evaluation by neurologists. It is not a unique diagnosis but rather a common manifestation of disorders with diverse mechanisms. Loss of consciousness is typically preceded by a prodrome of symptoms and sometimes there is a clear trigger. This article discusses several cases that illustrate the various causes of syncope. Reflex syncope is the most common type and includes neurally mediated, vasovagal, situational, carotid sinus hypersensitivity, and atypical forms. Acute and chronic autonomic neuropathies and neurodegenerative disorders can also present with syncope. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Derechos Digitales is a Latin American advocacy and research network focussed on freedom on the internet, privacy and copyright reform. For the pilot project a specific IDRC funded project was the notional focus of study. However in practice the effort for considering data sharing was aimed at being organisation wide. The organisation already shares reports and other resources (particularly images and infographics by default. While open data was described as being “in the DNA of the organisation” there was little practice across the network of sharing preliminary and in-process materials. Some aspects of data collection on research projects, particularly to do with copyright and legal issues, have significant privacy issues and as the organisation focuses on privacy as one of its advocacy areas this is taken very seriously. Many materials from research projects are not placed online at all. Derechos Digitales run distributed projects and this creates challenges for consistent management. Alongside this the main contact at DD changed during the course of the pilot. This exchange exemplified the challenges of maintaining organisational systems and awareness through a personnel change.

    Full Text Available Environmental sustainability of rural settlements based on a systematic viewpoint may be defined as a realization of sustainable development in different social, economic and environmental aspects of rural areas. Achieving this goal requires that we pay more attention to effective elements and factors through a set of sustainability indices. This research was meant to analyze sustainable factors of rural settlement in three dimensions: environmental, social and economic context using multi-criteria decision analysis and explanation of the relationships between its active and effective factors in the rural area of the Khorramdarreh County in the province of Zanjan. The research method used is the descriptive analytic approach. Data from 287 households were sampled randomly from a total of 1143 households in the four villages including: Rahmat Abad, Alvand, Baghdareh and, Sukhariz (out of 15 villages in the Khorramdarreh County. In the process of doing this research and after calculating the weights, the difference in the sustainability of environmental, social, economic and physical aspects in rural areas of this county have been determined. Data was collected using library and field research through questionnaires. Data analysis was performed by the One-Sample t Test and the Vikur and path analysis techniques, using statistical software SPSS. The findings show that environmental sustainability in the study area is half desirable. Among the different aspects of environmental sustainability, the most effective factors are physical, economic, social and environmental aspects, respectively. Little attention of policy-making –system to socio-cultural and environmental aspects, especially in practice, and rapid and unplanned utilization of production resources are the most important factors affecting this situation in two given dimensions. Although, in programmed documents the planning system agents emphasize on the socio-cultural sustainability

    These six case studies examined the use of different biodiesel blends as fuel supply sources for businesses in British Columbia (BC). In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not

    An outline is given of how IPSN and GRS assess the effects of physical ageing on the safety of French and German Nuclear Power Plants (NPPs) on the basis of the available knowledge and how investigations are carried out. The presentation is focused exemplary on a preliminary study illustrating approaches for the evaluation of the ageing behaviour of active components, the motor-operated valves (MOV). The results so far seems to demonstrate that the developed methodological approaches are suitable to obtain qualitative evidence with regard to the ageing behaviour of technical facilities such as MOV. The evaluation of the operating experience with French 900 MWe plants seems to reveal, for MOV of one system, a trend similar to some international findings about ageing-related events with increasing operating time; this trend will have to be confirmed. For the German NPPs so far, there appears to be no significant increase of ageing-related events concerning MOV as the plants get older. Future work on ageing scheduled at IPSN and GRS includes further cooperation on this issue, too; a deep analysis is necessary to explain the reasons of such apparent differences before any conclusion.

    Directed Self Assembly (DSA) using block copolymers (BCP) has received considerable attention over the past few years as a potential complementary lithographic technique. While many are focused on adapting DSA integrations to high volume manufacturing, the key to the technology's success lies in its ability to generate low defect patterns. The best way to drive the technology toward a zero defect solution is to understand the fundamentals of the block copolymer assembly, the interactions of the block copolymer with the underlying chemical pattern, and the evaluation of process parameters to obtain a high degree of order of the BCP morphologies. To this end, recent research has investigated numerous material, structural, and process sensitivities of an exemplary chemo-epitaxy line/space integration. Using the DSA flow implemented at imec, substrate properties, such as the geometry and chemistry, were studied and provided the first results regarding the dimensions of the nano-patterns and the energetic conditions necessary to obtain good alignment of the BCP. Additional parameters that have been explored include BCP film thickness and the bake conditions used to execute various steps of the flow. With this work, the key parameters that drive the assembly process have been identified. This will allow the definition of an optimized process window and materials for defect minimization.

  1. A case study of Impetigo

    Mansouri P

    1993-05-01

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

  2. Towards living within my body and accepting the past: a case study of embodied narrative identity.

    Sviland, Randi; Martinsen, Kari; Råheim, Målfrid

    2017-11-02

    This narrative case study, created from several qualitative sources, portrays a young woman's life experiences and an eight yearlong therapy process with Norwegian Psychomotor Physiotherapy (NPMP). It is analyzed retrospectively from an analytical angle, where NPMP theory is expanded with Løgstrup's phenomenology of sensation and Ricoeur's narrative philosophy. Understanding Rita's narrative through this window displayed some foundational phenomena in a singular way, illuminating embodied experiences in inter-subjective relationships in movement, sensation and time entwined. It illustrates how traumatic life experiences may cause pain, suffering and ruptured narratives with fragmented physical and sensuous reactions, chaos and loss of temporal coherence with consequences for a person's sense of identity. Rita's narrative also illuminates how intersubjective interaction has healing potentials when there is time and space for trust to emerge and to support new bodily-based experiences. Embodied sensuous experiences in present time may help clarify past and present and support chronology in narration and the sense of identity. With this exemplary case study, we argue that Løgstrup's and Ricoeur's thinking may add valuable perspectives to understanding suffering and healing processes in the field of embodied therapies like NPMP.

    Full Text Available Background. Multiple personality disorder is characterised by splited individual ego-states and splited professional community arguing whether this disorder actually exists or not.Methods. In this case report study a supportive psychodynamic psychotherapy of a patient with multiple personality disorder is presented, that lasted for 4.5 years and resulted in ego-reintegration.Conclusions. The spliting between different ego-states is powered by unneutralised aggression with the possibility of hetero- and autoaggressive behaviour. Therefore the patient in the analytically oriented psychotherapeutic process is at high risk and a safe therapeutic (e. g. in-patient setting has to be provided.

    The combination of the Hadoop MapReduce programming model and cloud computing allows biological scientists to analyze next-generation sequencing (NGS) data in a timely and cost-effective manner. Cloud computing platforms remove the burden of IT facility procurement and management from end users and provide ease of access to Hadoop clusters. However, biological scientists are still expected to choose appropriate Hadoop parameters for running their jobs. More importantly, the available Hadoop tuning guidelines are either obsolete or too general to capture the particular characteristics of bioinformatics applications. In this paper, we aim to minimize the cloud computing cost spent on bioinformatics data analysis by optimizing the extracted significant Hadoop parameters. When using MapReduce-based bioinformatics tools in the cloud, the default settings often lead to resource underutilization and wasteful expenses. We choose k-mer counting, a representative application used in a large number of NGS data analysis tools, as our study case. Experimental results show that, with the fine-tuned parameters, we achieve a total of 4× speedup compared with the original performance (using the default settings). Finally, this paper presents an exemplary case for tuning MapReduce-based bioinformatics applications in the cloud, and documents the key parameters that could lead to significant performance benefits.

    Ultrasonic testing is widely used Non Destructive Testing (NDT) method and forms the essential part of In-service inspection programme of nuclear reactors. Main application of ultrasonic testing is for volumetric scanning of weld joints followed by thickness gauging of pipelines and pressure vessels. Research reactor Dhruva has completed the first In Service Inspection programme in which about 325 weld joints have been volumetrically scanned, in addition to thickness gauging of 300 meters of pipe lines of various sizes and about 24 nos of pressure vessels. Ultrasonic testing is also used for level measurements, distance measurements and cleaning and decontamination of tools. Two case studies are brought out in this paper in which ultrasonic testing is used successfully for identification of butterfly valve opening status and extent of choking in pipe lines in Dhruva reactor systems

    2014-01-01

    Full Text Available 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.

    2004-01-01

    This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most...... useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one...... and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more...

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    2016-03-01

    Full Text Available This study focuses on the qualities of Chinese university professors as perceived by their students and the effects of those qualities on student learning and motivation. Specifically, what qualities and personal characteristics do Chinese university students attribute to their favorite and least favorite professors, and how do those qualities and characteristics affect Chinese university students? Out of 280 students surveyed from three different universities, 226 surveys were completed, returned and included in the final analysis (response rate of 80.7%. The research found that Chinese students favored professors who are entertaining, who help them learn more and who provide them with helpful feedback on their assignments. Students disfavor professors who are boring, arrogant and do not provide helpful feedback or help them learn more. Linear regressions revealed a connection between high quality professors and student learning and motivation. Along with other studies, this research provides evidence that effective university professors are those who not only possess expertise in their fields, but in addition are engaging, student-focused and able to build rapport with their students.

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

    Current models of health care quality improvement do not explicitly describe the role of health professions education. The authors propose the Exemplary Care and Learning Site (ECLS) model as an approach to achieving continual improvement in care and learning in the clinical setting. From 2008-2012, an iterative, interactive process was used to develop the ECLS model and its core elements--patients and families informing process changes; trainees engaging both in care and the improvement of care; leaders knowing, valuing, and practicing improvement; data transforming into useful information; and health professionals competently engaging both in care improvement and teaching about care improvement. In 2012-2013, a three-part feasibility test of the model, including a site self-assessment, an independent review of each site's ratings, and implementation case stories, was conducted at six clinical teaching sites (in the United States and Sweden). Site leaders reported the ECLS model provided a systematic approach toward improving patient (and population) outcomes, system performance, and professional development. Most sites found it challenging to incorporate the patients and families element. The trainee element was strong at four sites. The leadership and data elements were self-assessed as the most fully developed. The health professionals element exhibited the greatest variability across sites. The next test of the model should be prospective, linked to clinical and educational outcomes, to evaluate whether it helps care delivery teams, educators, and patients and families take action to achieve better patient (and population) outcomes, system performance, and professional development.

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

  5. Regional case studies--Africa.

    Prentice, Andrew M

    2009-01-01

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

    1997-12-31

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

  16. A Case Study Based Analysis of Performance Metrics for Green Infrastructure

    2017-12-01

    Aging infrastructure, population growth, and urbanization are demanding new approaches to management of all components of the urban water cycle, including stormwater. Traditionally, urban stormwater infrastructure was designed to capture and convey rainfall-induced runoff out of a city through a network of curbs, gutters, drains, and pipes, also known as grey infrastructure. These systems were planned with a single-purpose and designed under the assumption of hydrologic stationarity, a notion that no longer holds true in the face of a changing climate. One solution gaining momentum around the world is green infrastructure (GI). Beyond stormwater quality improvement and quantity reduction (or technical benefits), GI solutions offer many environmental, economic, and social benefits. Yet many practical barriers have prevented the widespread adoption of these systems worldwide. At the center of these challenges is the inability of stakeholders to know how to monitor, measure, and assess the multi-sector performance of GI systems. Traditional grey infrastructure projects require different monitoring strategies than natural systems; there are no overarching policies on how to best design GI monitoring and evaluation systems and measure performance. Previous studies have attempted to quantify the performance of GI, mostly using one evaluation method on a specific case study. We use a case study approach to address these knowledge gaps and develop a conceptual model of how to evaluate the performance of GI through the lens of financing. First, we examined many different case studies of successfully implemented GI around the world. Then we narrowed in on 10 exemplary case studies. For each case studies, we determined what performance method the project developer used such as LCA, TBL, Low Impact Design Assessment (LIDA) and others. Then, we determined which performance metrics were used to determine success and what data was needed to calculate those metrics. Finally, we

    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

    Full Text Available The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or ‘Classical psychoanalysis’ dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    Many schools rely upon community preceptors for office-based education of medical students. These preceptors struggle to balance clinical care with the learning needs of students. We aim to gain a deeper understanding of the teaching rewards and challenges of current community preceptors. Five schools' family medicine clerkship directors conducted in-depth interviews of two exemplary preceptors at each of their programs. Following qualitative analysis of the interviews, three directors conducted one focus group at their school. The individual and group interviews were recorded, transcribed, and analyzed using grounded theory. Exemplary community preceptors described strategies to improve the learning environment and specific teaching approaches. Well-known teaching strategies such as role modeling, adjusting instruction to the learner's needs, and selecting patients appropriate for a specific student were used. They also described newer techniques such as co-learning and integrating technology, for example, accessing online, current practice guidelines together with the student. They detailed challenges to teaching, including time constraints and too much content to cover and provided advice about teaching tools. While challenged by clinical demands, preceptors enjoyed teaching and found it rewarding. They used time-proven teaching strategies as well as technology and online resources to facilitate ambulatory teaching. Community preceptors continue to struggle to integrate learners and the priorities of the medical school curriculum into the clinical environment. Further development of electronic tools and other resources to support the teaching needs of preceptors may contribute to learning and help minimize preceptor burden.

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    2013-10-01

    This article addresses ethical issues relative to the conduct and reporting of psychobiographical research. The author's recent psychobiographical study of World Chess Champion Bobby Fischer (1943-2008) is used to illustrate particular ethical challenges and responses in six areas: (1) institutional review board (IRB) evaluation and informed consent; (2) balancing objective research with respect for psychobiographical subject; (3) inviting subject or next-of-kin to read and comment on working drafts of psychobiography; (4) reporting never-before-revealed sensitive information on a subject; (5) role of interdisciplinary consultation in conducting psychobiography; and (6) the value and cautions of including psychological diagnoses as part of the psychological profile. A "bill of rights and responsibilities" for the psychobiographer is introduced as a stimulus for ongoing discussion and empirical research on ethical practice in psychobiography.

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient''s high risk of strokes and hemorrhaging prompted investigation by a 99 mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome

Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

  15. An Exemplary Case of Promotion Activities and Taste Panels from the Perspective of Tobacco Control

    Science.gov (United States)

    Mutlu, Erdem İlker; Seydioğulları, Mustafa; Aslan, Dilek

    2015-01-01

    The Framework Convention on Tobacco Control is a multilateral international agreement which has been generated to protect the health of nationals and nations against the hazards/risks of tobacco and its products. All high contracting parties to the Convention undertake the international responsibility to fulfill all the requirements of the Convention’s articles in national legal systems. The Framework Convention on Tobacco Control has a considerable place among other international conventions on health. Within the self-executing desing/system of the Convention, a vital regulation focuses on banning the advertisement, promotion, and sponsorship of tobacco products. Because they are one of the various components of tobacco advertisement, promotion, and sponsorship, taste panels should be assessed within the content of the Convention. Thus, banning taste panel activities is an important step in tobacco control and it is one of the basic areas where medical and law sciences should collaborate. In this article, a comprehensive frame has been drawn to the issue and recommendations have been developed for the future. PMID:29404102

    Nesvick, Cody L; Thompson, Clinton J; Boop, Frederick A; Klimo, Paul

    2014-08-01

    Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

  1. Towards More Case Study Research in Entrepreneurship

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

  6. Rethinking Case Study Methodology in Poststructural Research.

    Little consideration has been given to how case study might be used in poststructural research to explore power relations that constitute a phenomenon. Many case study scholars, most notably Robert Yin, adopt a postpositivist perspective that assumes the "truth" can be accessed through applying prescriptive and rigid research techniques. Using a discussion of Michel Foucault's key theoretical ideas and the insights gained through a Foucauldian case study of people with advanced cancer who continue to receive curative treatment, the authors argue for the expansion of case study in poststructural inquiry. They propose that the use of poststructuralist case study is valuable because of the flexibility and comprehensiveness of the methodology, which allows for the exploration of a deeper understanding of the broader discourses that shape a phenomenon, as well as how power/knowledge relations shape the behaviours and perceptions of people. They also introduce the reflexive implications of poststructural case study research. Copyright© by Ingram School of Nursing, McGill University.

  7. Performable Case Studies in Ethics Education.

    Robeson, Richard; King, Nancy M P

    2017-09-12

    Bioethics education often includes the study of short stories, novels, plays, and films, because such materials present case examples that can highlight relevant issues and questions especially vividly for a wide range of students. In addition, creative writing is widely used in the education of health professional students and in continuing education settings for health professionals. There are very few academic or professional disciplines that do not use case studies, but the case study in dialogic form has not been standard practice for thousands of years. Dramatic arts casuistry-the creation and performance of short case studies designed specifically to raise bioethics issues for discussion-represents an application of literature and the medical humanities that is both unique and uniquely valuable. This essay describes the development and history of a course that has been successfully taught to medical students and graduate bioethics students, in which the class researches, writes, and performs a case study designed to elicit reflection and discussion about a topic and set of bioethics issues of current interest to both academic and general audiences. The model is also suited to the presentation and discussion of existing case studies, both live and via on-demand audio.

    Full Text Available Background : Anencephaly is a lethal neural tube defect which is due to the defective closure of rostral pore of neural tube. In more than 50% of cases it is associated with other systemic anomalies. Hence this study was undertaken to assess pathological parameters associated with anencephaly in particular attention to associated systemic anomalies. Materials and Methods: It is a study on 41 anencephaly fetuses conducted in the Department of Pathology. The period of study is from January 2001 to December 2011. Results: Out of 41 cases, 30 (73% cases showed presence of systemic anomalies, 48.5% of the cases were observed in primigravida. Most common associated anomaly was spina bifida followed by gastrointestinal anomalies. Conclusion: Pathological examination of the abortus is essential to document the associated anomalies.

    Through data collection methods using a holistic approach that focuses on variables in a natural setting, qualitative research methods seek to understand participants' perceptions and interpretations. Common qualitative research methods include ethnography, phenomenology, grounded theory, and historic research. Another type of methodology that has a similar qualitative approach is case study research, which seeks to understand a phenomenon or case from multiple perspectives within a given real-world context.

    1995-09-01

    Personal social values have been identified as important determinants of generalists' specialty choice. However, the personal values or "guiding principles" of generalist physicians have not been identified scientifically. To establish a benchmark, we measured the personal values of exemplary family physicians because they serve as role models for current and future physicians. We also explored the relationship between personal values and practice satisfaction. We obtained a list of 330 family physicians nominated for the American Academy of Family Physicians' (AAFP) Family Doctor of the Year award for the years 1988 through 1993. We asked them to complete the Schwartz Values Questionnaire, a 56-item instrument for measuring personal values. They also answered three questions concerning practice satisfaction. The return rate was 83%. The physicians' mean age was 63 years. They had been in practice an average of 34 years, 93% were male, and 52% practiced in rural areas. Honesty was rated as the most important of the 56 values, and social power as the least important. Of the 10 value types (groups of common values), the responding physicians rated "Benevolence" as most important and "Power" as least important. Practice satisfaction correlated positively with the Benevolence value type (r = .21, P = .001) and negatively with the Power value type (r = -.15, P = .023). Of the 10 value types, Benevolence was rated the most important and Power the least important by exemplary family physicians, and both value types also correlated, positively and negatively, respectively, with their practice satisfaction. These results have implications for the selection, training, and career satisfaction of generalist physicians.

  6. Do cost savings from reductions in nosocomial infections justify additional costs of single-bed rooms in intensive care units? A simulation case study.

    2016-02-01

    Evidence shows that single-patient rooms can play an important role in preventing cross-transmission and reducing nosocomial infections in intensive care units (ICUs). This case study investigated whether cost savings from reductions in nosocomial infections justify the additional construction and operation costs of single-bed rooms in ICUs. We conducted deterministic and probabilistic return-on-investment analyses of converting the space occupied by open-bay rooms to single-bed rooms in an exemplary ICU. We used the findings of a study of an actual ICU in which the association between the locations of patients in single-bed vs open-bay rooms with infection risk was evaluated. Despite uncertainty in the estimates of costs, infection risks, and length of stay, the cost savings from the reduction of nosocomial infections in single-bed rooms in this case substantially outweighed additional construction and operation expenses. The mean value of internal rate of return over a 5-year analysis period was 56.18% (95% credible interval, 55.34%-57.02%). This case study shows that although single-patient rooms are more costly to build and operate, they can result in substantial savings compared with open-bay rooms by avoiding costs associated with nosocomial infections.

    In Switzerland, screening concepts for the prevention of sports-associated sudden cardiac death are still insufficiently established in the large group of competitive athletes who are not integrated in an Olympic- or other high-level squad. The aim of the present study was to objectively determine the current situation in this particular group of athletes concerning cardiac pre-competition screening and define specific features of an "ideal" Swiss screening concept. Based on these data, the feasibility and validity was tested by the implementation of an exemplary local screening programme. A standardised questionnaire was completed by 1,047 competitive athletes of different ages and gender. The individual, sports-specific profile of an athlete and furthermore, the personal attitude towards and the vision of a "perfect" cardiac screening were assessed. Based on the results, an exemplary local screening programme for competitive athletes was implemented at the "Academic Sports Association Zurich" (ASVZ) in Zurich, Switzerland and evaluated 1 year after its introduction. Only 9% of the 1,047 interviewed competitive athletes (aged 13 to 64 years; median age 22 years, SD = 5.87) had previously undergone a cardiac screening. Only 47% of the interviewed competitive athletes expressed their interest to undergo a cardiac screening at all. Male and older athletes showed a significantly higher acceptance rate for the screening programme than women and younger athletes. All athletes accepted to bear the expenses for the baseline screening programme, adapted to international standards (minimal accepted fee of 60 Swiss Francs). Almost half of the athletes (49.2%) preferred easy accessibility to a sports cardiologist (max. distance of 10 kilometres). The exemplary local screening programme proved to be feasible and successful. However, only 30% of the 102 screened individuals were female and most of the athletes (80%) who made use of the screening had a specific concern or

    2016-09-01

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    Science.gov (United States)

    This draft document presents two case studies of nanoscale titanium dioxide (nano-TiO2) used (1) to remove arsenic from drinking water and (2) as an active ingredient in topical sunscreen. The draft case studies are organized around a comprehensive environmental assessment approach that combines a product life cycle framework with the risk assessment paradigm. The document does not draw conclusions about potential risks. Rather, the case studies are intended to help identify what needs to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. This draft document is part of a process that will inform the development of EPA’s research strategy to support nanomaterial risk assessments. The complex properties of various nanomaterials make evaluating them in the abstract or with generalizations difficult if not impossible. Thus, this document focuses on two specific uses of nano-TiO2, as a drinking water treatment and as topical sunscreen. These case studies do not represent completed or even preliminary assessments; rather, they present the structure for identifying and prioritizing research needed to support future assessments.

  14. Neonatal appendicitis: a survival case study

    Directory of Open Access Journals (Sweden)

    Izabela Linha Secco

    Full Text Available ABSTRACT Objective: To report a case of neonatal appendicitis in a children’s hospital in southern Brazil, demonstrating the impact on neonatal survival. Method: Case study with data collection from medical records, approved by the Institution and Ethics Committee for Research with Human Beings. Results: The clinical picture is initially characterized by food intolerance, evolving to hypoactivity, alteration of vital signs and septicemia due to intestinal perforation. Management is exclusively surgical, since no case described in the literature was diagnosed preoperatively and the findings usually point to acute abdomen. Conclusion: A focused clinical surveillance should be established when the infant presents peritoneal irritation. Follow-up of the evolution and the worsening of the symptoms by nurses, as part of the care team in partnership with the medical team, enables an early surgical intervention, thereby avoiding complications such as septicemia and death.

    2014-09-01

    Adult dermatomyositis presents as a paraneoplastic syndrome in up to 25% of cases, but no clinical, histologic, or laboratory markers completely specific for paraneoplastic disease in dermatomyositis have been identified to date. Furthermore, studies on adult dermatomyositis do not usually report the frequency of cutaneous features of dermatomyositis in patients with associated cancer. Our aim was to review the characteristics of paraneoplastic dermatomyositis in patients seen at our hospital. We studied 12 cases of paraneoplastic dermatomyositis and recorded patient age and sex, associated cancer, time between onset of dermatomyositis and cancer, emergent cutaneous manifestations, muscle involvement, dysphagia, lung disease, and levels of creatine phosphokinase and circulating autoantibodies. The mean age of the patients was 61 years and the 2 most common malignancies were ovarian cancer and bladder cancer. The mean time between the diagnosis of cancer and dermatomyositis was 7 months and in most cases, the cancer was diagnosed first. Seven patients had amyopathic dermatomyositis. The most common cutaneous signs were a violaceous photodistributed rash sparing the interscapular area and a heliotrope rash, followed by Gottron papules and cuticle involvement. Superficial cutaneous necrosis was observed in 3 cases. Myositis-specific autoantibodies were not detected in any of the 6 patients who underwent this test. Paraneoplastic dermatomyositis is often amyopathic. There are no specific cutaneous markers for malignancy in dermatomyositis. Myositis-specific antibodies are not associated with paraneoplastic dermatomyositis. Copyright © 2013 Elsevier España, S.L.U. y AEDV. All rights reserved.

    Based on today's information and communication technologies the open access paradigm has become an important approach for adequately communicating new scientific knowledge. Summarizing the present situation for journal transformation. Presenting criteria for adequate transformation as well as a specific approach for it. Describing our exemplary implementation of such a journal transformation. Studying the respective literature as well as discussing this topic in various discussion groups and meetings (primarily of editors and publishers, but also of authors and readers), with long term experience as editors and /or publishers of scientific publications as prerequisite. There is a clear will, particularly of political and funding organizations, towards open access publishing. In spite of this, there is still a large amount of scientific knowledge, being communicated through subscription-based journals. For successfully transforming such journals into open access, sixteen criteria for a goal-oriented, stepwise, sustainable, and fair transformation are suggested. The Tandem Model as transformation approach is introduced. Our exemplary implementation is done in the Trans-O-MIM project. It is exploring strategies, models and evaluation metrics for journal transformation. As instance the journal Methods of Information in Medicine will apply the Tandem Model from 2017 onwards. Within Trans-O-MIM we will reach at least nine of the sixteen criteria for adequate transformation. It was positive to implement Trans-O-MIM as international research project. After first steps for transforming Methods have successfully been made, challenges will remain, among others, in identifying appropriate incentives for open access publishing in order to support its transformation.

    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. 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. 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. The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

  12. AR.Drone: security threat analysis and exemplary attack to track persons

    Science.gov (United States)

    Samland, Fred; Fruth, Jana; Hildebrandt, Mario; Hoppe, Tobias; Dittmann, Jana

    2012-01-01

    In this article we illustrate an approach of a security threat analysis of the quadrocopter AR.Drone, a toy for augmented reality (AR) games. The technical properties of the drone can be misused for attacks, which may relate security and/or privacy aspects. Our aim is to sensitize for the possibility of misuses and the motivation for an implementation of improved security mechanisms of the quadrocopter. We focus primarily on obvious security vulnerabilities (e.g. communication over unencrypted WLAN, usage of UDP, live video streaming via unencrypted WLAN to the control device) of this quadrocopter. We could practically verify in three exemplary scenarios that this can be misused by unauthorized persons for several attacks: high-jacking of the drone, eavesdropping of the AR.Drones unprotected video streams, and the tracking of persons. Amongst other aspects, our current research focuses on the realization of the attack of tracking persons and objects with the drone. Besides the realization of attacks, we want to evaluate the potential of this particular drone for a "safe-landing" function, as well as potential security enhancements. Additionally, in future we plan to investigate an automatic tracking of persons or objects without the need of human interactions.

    2012-01-01

    A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

  14. Systemic Design: Two Canadian Case Studies

    Directory of Open Access Journals (Sweden)

    Alex Ryan

    2014-12-01

    Full Text Available This paper introduces two novel applications of systemic design to facilitate a comparison of alternative methodologies that integrate systems thinking and design. In the first case study, systemic design helped the Procurement Department at the University of Toronto re-envision how public policy is implemented and how value is created in the broader university purchasing ecosystem. This resulted in an estimated $1.5 million in savings in the first year, and a rise in user retention rates from 40% to 99%. In the second case study, systemic design helped the clean energy and natural resources group within the Government of Alberta to design a more efficient and effective resource management system and shift the way that natural resource departments work together. This resulted in the formation of a standing systemic design team and contributed to the creation of an integrated resource management system. A comparative analysis of the two projects identifies a shared set of core principles for systemic design as well as areas of differentiation that reveal potential for learning across methodologies. Together, these case studies demonstrate the complementarity of systems thinking and design thinking, and show how they may be integrated to guide positive change within complex sociotechnical systems.

    Goodman, S. J.; Ritschard, R.; Estes, M. G., Jr.; Hatch, U.

    2001-01-01

    The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

Her case demonstrated how administrators and faculty learn about the experience and struggles endured by international students, especially those who learned English a short time before admission to graduate studies. While a single case is understandably idiographic in nature and inevitably requires a larger sample, from the analysis of Angélica’s case and the analysis of the relevant literature common topics emerged persuading me to conclude that the issues that commonly impact the life of international students have to do with: 1 second language problems; 2 the quality of academic advisement received; 3 the availability of financial support; 4 the level of integration into their academic program; and 5 the level of cultural adjustment in their host country.

    Hassaan Tohid

    Full Text Available Abstract Introduction: The world renowned comedian and four-time Oscar nominated actor Robin Williams died on August 11, 2014. From the outset, the news indicated that his death was believed to be a suicide and this was later confirmed to be true by the autopsy reports. Williams had been suffering from severe depression, which is believed to be the leading contributor to his suicide. In this case study, I will highlight the event of the actor's suicide and the main risk factors along with depression leading to his tragic death. As of the end of 2015, no other case study seemed to have addressed or explored the links between the cause (or causes and events leading to Robin Williams' suicide. Case description: Robin Williams was suffering from relationship problems, financial problems, drug addiction, and major depression. All of these factors led to his suicide. Comments: The chances of committing suicide drastically increase in the presence of any of the key risk factors. Unfortunately, the actor Robin Williams was dealing with four of the major risk factors all together, which put him at a high risk of committing suicide and eventually led to his tragic death.

    Full Text Available Abstract The term semantic dementia was devised by Snowden et al. in 1989 and nowadays, the semantic dementia syndrome is recognized as one of the clinical forms of frontotemporal lobar degeneration (FTLD and is characterized by a language semantic disturbance associated to non-verbal semantic memory impairment. Objectives: The aim of this study was to describe a Brazilian sample of 19 semantic dementia cases, emphasizing the clinical characteristics important for differential diagnosis of this syndrome. Methods: Nineteen cases with semantic dementia were evaluated between 1999 and 2007. All patients were submitted to neurological evaluation, neuroimaging exams and cognitive, language and semantic memory evaluation. Results: All patients presented fluent spontaneous speech, preservation of syntactic and phonological aspects of the language, word-finding difficulty, semantic paraphasias, word comprehension impairment, low performance in visual confrontation naming tasks, impairment on tests of non-verbal semantic memory and preservation of autobiographical memory and visuospatial skills. Regarding radiological investigations, temporal lobe atrophy and/or hypoperfusion were found in all patients. Conclusions: The cognitive, linguistic and of neuroimaging data in our case series corroborate other studies showing that semantic dementia constitutes a syndrome with well defined clinical characteristics associated to temporal lobe atrophy.

  20. Nanomaterial Case Studies: Nanoscale Titanium Dioxide in ...

    Science.gov (United States)

    EPA announced the availability of the final report, Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen. This report is a starting point to determine what is known and what needs to be known about selected nanomaterials as part of a process to identify and prioritize research to inform future assessments of the potential ecological and health implications of these materials. Two specific applications of nanoscale titanium dioxide (nano-TiO2) are considered: (1) as an agent for removing arsenic from drinking water; and (2) as an active ingredient in topical sunscreen. These case studies are organized around a comprehensive environmental assessment (CEA) framework that combines a product life cycle perspective with the risk assessment paradigm. They are intended to help identify what may need to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. These “case studies” do not represent completed or even preliminary assessments, nor are they intended to serve as a basis for risk management decisions in the near term on these specific uses of nano TiO2. Rather, the intent is to use this document in developing the scientific and technical information needed for future assessment efforts.

    To study the epidemiology, diagnosis, treatment strategies and perinatal outcomes of gestational syphilis. We performed a retrospective study of 94 pregnant women with syphilis whose gestation and delivery were monitored in a Department of Obstetrics from 2002 to 2010 among a total of 85,806 births of women without syphilis in the same period. The prevalence of gestational syphilis was 0.11%. Most of the women were foreign and the most prevalent type was late latent syphilis. Only 57 patients underwent right treatment despite adequate prescription. Maternal complications were confirmed in 31 pregnant women and 16 cases had fetal complications. We diagnosed 4 cases of neonatal syphilis, 3 of them with syphilitic meningitis, whose mothers had not completed the treatment correctly. The implementation of a mandatory syphilis serology in the pregnancy has enabled us to diagnose many cases of late latent syphilis. The successful completion of treatment must be ensured to prevent vertical transmission. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.

    2013-04-01

    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

    1983-01-01

    Scintigraphy is just right for diagnosing emergency cases due to its noninvasive and simple method, but emergency radionuclide studies have not become practical as a result of difficulty problems. Recently, nuclear medical devices have become easier to use in operations. It is become of this, that I have submitted this report regarding the problems of radionuclide studies in emergency cases. There were 101 cases (1.4 %) out of 7,310 cases for the year period Sept. 1981 - Aug. 1982. The studies consisted of 12 brain imaging cases, 9 plumonary imaging cases, 22 cardiac study cases (cardio-angiography cases 8, 99m-Tc-PYP myocardium imaging cases 12, 201-Tl myocardium imaging cases 2), 12 renal study cases, 11 G.I. blood loss cases, 35 peripheral angiography cases. In the near future, we will have to be ready to perform emergency radionuclide studies if the need arises. (author)

    2009-12-01

    Full Text Available Abstract Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs. Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5. The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11. In the second

    Full Text Available Currently, in information technology domain and implicit in databases domain can be noticed two apparently contradictory approaches: centralization and distribution respectively. Although both aim to produce some benefits, it is a known fact that for any advantage a price must be paid. In addition, in this paper we have presented a case study, e-learning portal performance optimization by using distributed databases technology. In the stage of development in which institutions have branches distributed over a wide geographic area, distributed database systems become more appropriate to use, because they offer a higher degree of flexibility and adaptability then centralized ones.

    Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.

    To study the epidemiological and clinical features and diagnostic tests of Cushing's syndrome (CS) of non-iatrogenic etiology, because of there are few similar studies in the last ten years. Fifteen cases of CS were diagnosed from 1992 to 1997 at our hospital. We describe the epidemiological, clinical, biochemical, radiologic, therapeutic and evolutive characteristics. Both diabetes mellitus and hypertension were observed in 40% of patients. The frequency of etiologies was: Cushing's disease, 66.6%; ectopic ACTH syndrome, 13.3%; adrenal adenoma, 6.6%; adrenal carcinoma, 6.6%; and undiagnosed, 6.6%. The 24-hour urine free cortisol (UFC) and the overnight 1 mg oral dexamethasone suppression test yielded 93.3 and 100% diagnostic sensitivity for CS, respectively. The overnight 8 mg oral dexamethasone suppression test, the metyrapone test and the 7 mg intravenous dexmethasone test had 75, 50 and 60% diagnostic sensitivity for Cushing's disease, respectively. Ketoconazole treatment had success in to normalize the 24-hour UFC in all patients, except for the case of adrenal carcinoma. The Cushing's disease was the most common form of CS. The 24-hour UFC and overnight 1 mg oral dexamethasone suppression test were good screening studies. Ketoconazole was successful in normalizing the adrenal cortex function.

    The term environmental qualification is used for assurance or guarantee for satisfactory performance of hardware under specified environmental conditions including normal, abnormal and accident conditions. To generate confidence about satisfactory performance in reasonable time, hardware must be tested under accelerated conditions. For testing and measuring performance parameters, it is essential to have adequate facilities and experienced and inquisitive staff so that qualified and reliable hardware can be manufactured by active participation of manufacturers, users and researchers. Top priority is given to the determination of characteristics, capabilities and limitations of hardware before really starting accelerated testing so that maximum information can be extracted before failure of hardware. This paper describes test and measurement facilities set up at the Bhabha Atomic Research Centre for environmental qualification and some case studies where it has been possible to make significant contributions towards reliability assessment, upgrading and indigenisation. Apart from climatic test facilities (thermal and humidity chambers), a Loss Of Coolant Accident (LOCA) environment simulator and synergistic simulator (combined environment test facility comprising temperature, humidity, gamma radiation and electrical stresses for studying interaction effects) have been set up. Notable case studies are :(1) Assessment of residual life-spans of cables and elastomeric components, (2) Reliability upgradation of indicating alarm meters and solenoid valves, (3) Assessment of survival capability of process instruments under LOCA environment, (4)Assessment of reusability of relays exposed to smoke and water spray in fire incident in a nuclear power station.

  6. Believe it or not: A case study of the role beliefs play in three middle school teachers' use of computers in teaching science

    Science.gov (United States)

    Feldman, Carmia Suzannah

    In the past twenty years, teacher beliefs have been found to have a strong influence on the way teachers teach in many disciplines, but only recently is research being done in relation to teaching with computers. As computers become more ubiquitous in schools, it is more important than ever to determine how computers are being used in classrooms, how they could better support student learning, and the reasons why they may not be used in ways advocated by research. In this study, I used a conceptual model of the beliefs that have been shown to influence teaching behavior, an in-depth interview technique (Munby Repertory Grid Technique---RGT) to uncover beliefs, and an exemplary case study methodology to highlight the relationship between the beliefs and teaching with computer behaviors of three middle school teachers. The cases were exemplary in that many of the barriers research has shown to hinder teachers' ability to integrate computers in their teaching were minimized. The teachers all taught at the same technology magnet school and had strong administrative and technological support, professional development in the use of computers, and permanent access to student laptop computers equipped with wireless Internet. To get a complete picture of the teachers' belief systems, I used the Munby RGT with each teacher to explore their teaching with computer beliefs, their science teaching beliefs, and their general teaching beliefs. I then collected data on their teaching with computer behavior through classroom observations, lesson plan report forms, teaching behavior logs, and written reflections, among others. I found that the teachers' beliefs did influence their teaching with computer behavior. For example, although all teachers expressed beliefs that could support student-centered and inquiry-based teaching with computers, some of their beliefs, such as teacher-centered behavioral management beliefs, were more dominant and may have kept the teachers from reaching

    We conducted a one-year prospective study involving a prehospital Emergency Medical Service in the Netherlands to investigate the incidence of failed or difficult prehospital endotracheal intubation. During the study period the paramedics were asked to fill in a registration questionnaire after every endotracheal intubation. Of the 26,271 patient contacts, 256 endotracheal intubations were performed by paramedics in one year. Endotracheal intubation failed in 12 patients (4.8%). In 12.0% of 249 patients, a Cormack and Lehane grade III laryngoscopy was reported and a grade IV laryngoscopy was reported in 10.4%. The average number of endotracheal intubations per paramedic in one year was 4.2 and varied from zero to a maximum of 12. The median time between arrival on the scene and a positive capnograph was 7 min.38 s in the case of a Cormack and Lehane grade I laryngoscopy and 14 min.58 s in the case of a Cormack and Lehane grade 4 laryngoscopy. The incidence of endotracheal intubations performed by Dutch paramedics in one year was low, but endotracheal intubation was successful in 95.2%, which is comparable with findings in international literature. Early capnography should be used consistently in prehospital airway management.

    The world renowned comedian and four-time Oscar nominated actor Robin Williams died on August 11, 2014. From the outset, the news indicated that his death was believed to be a suicide and this was later confirmed to be true by the autopsy reports. Williams had been suffering from severe depression, which is believed to be the leading contributor to his suicide. In this case study, I will highlight the event of the actor's suicide and the main risk factors along with depression leading to his tragic death. As of the end of 2015, no other case study seemed to have addressed or explored the links between the cause (or causes) and events leading to Robin Williams' suicide. Robin Williams was suffering from relationship problems, financial problems, drug addiction, and major depression. All of these factors led to his suicide. The chances of committing suicide drastically increase in the presence of any of the key risk factors. Unfortunately, the actor Robin Williams was dealing with four of the major risk factors all together, which put him at a high risk of committing suicide and eventually led to his tragic death.

    Full text: This case study represents an example of the utility of postural hypoperfusion stressed HMPAO SPECT. An elderly woman of 78 with a long history of giddiness was referred to our laboratory for examination of possible cerebral ischaemia. She had recurrent dizzy episodes, sometimes posture related, over the past few years and had suffered several falls. Cerebral DSA revealed minimal disease. CT scans were reported as normal. Carotid duplex Doppler studies revealed bilateral plaque disease in the carotid bulbs extending to the origins of the ICAs which were not significant stenoses. Postural symptoms were induced by standing the patient up rapidly and HMPAO was administered at the same time. A SPECT scan of the brain was performed. Quantitative analysis showed a left to right decrease of 10.8% in the temporo-occipital area, 5.6% in the temporo-parietal area and 2.5% in the cerebellar and parietal areas. Images revealed moderately reduced tracer concentration in the left half of the cerebellum and the left occipital region extending as far forward as the temporo-parietal region A repeat HMPAO SPECT scan without stress was normal. This would appear to indicate reversible ischaemia in the left posterior region, and is consistent with the reported symptoms. This case illustrates the usefulness of HMPAO in the diagnosis of reversible cerebral ischaemia.

    California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

    Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

    Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

    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.

  18. Embodiment of the Spirit: A Case Study

    Full Text Available Adopting a longitudinal approach to exploring the psychology of the transition from military to civilian life, one case study is presented that adds a spiritual perspective to the transition process. This case study serves as an example representative from a group of participants who have been followed through a research project on identity reconstruction during the transition to civilian life. This individual, not unlike many others within the group, undergoes an unexpected progression of the military I-position of the self throughout the process of becoming a civilian. This study utilizes a dialogical approach to the identity work to further the understanding of longitudinal adjustments to the self. An analysis of the narrative developments and interactions among pre-existing and new I-positions of the self over time has been made based upon three annually conducted interviews spanning from 2014 to 2016. The results lead to the suggestion that if a military I-position of the self grows more salient and voiced throughout the process of transitioning into civilian life, then this vocalization may be related to the spirit of a person embodied in a specific I-position of the self. Such growth of a military I-position after leaving active service may gravitate around a deep sense of “who I am” with a profound sense of meaning attached to this position. Instead of perceiving as an unwanted development the growth of a military sense of “who I am,” one should acknowledge it as a deeper dimension of self and life. It is important to find an outlet for such a progression of the self so as to sustain balance and dialogue. Future research is encouraged to further examine these qualitative findings.

    Full Text Available The Bologna Process at National Higher Education Programs initiated a series of studies regarding the assessment and evaluation of quality in higher education. Dokuz Eylül University has taken this initiation into a primary concern to develop a methodology for the measurement of quality in undergraduate education. Besides the existing systems on this subject at Dokuz Eylül University, substantial progress was recently made by developing innovative sub-systems aiming further improvements. As one of the most important stakeholders, the feedback from students about the quality of the courses was selected as the major concern and a Student Course Feedback System was developed for this purpose. As an exemplary case study, this reveals how the Student Course Feedback System was designed, the process, the technologies used, the problems and constraints encountered, and the roadmap that can be followed by other universities. Dokuz Eylül University has interiorized this process as a corporate culture by directing instructors to make improvements in the courses with respect to the outputs of the evaluation forms, including questions about learning outcomes, instructors, and physical conditions. The integrated design of the Student Course Feedback System with the existing information systems has enabled management to implement a course evaluation system comprising the trilogy of students, instructors, and courses as a whole. The existence of such an assessment process supports the principles of continuous improvement and helps to establish the factual decision making process as an important milestone on the roadmap for a living quality assurance system.

    : A capable workforce is central to the delivery of high-quality care. Research from other industries suggests that the methodical use of evidence-based management practices (also known as high-performance work practices [HPWPs]), such as systematic personnel selection and incentive compensation, serves to attract and retain well-qualified health care staff and that HPWPs may represent an important and underutilized strategy for improving quality of care and patient safety. : The aims of this study were to improve our understanding about the use of HPWPs in health care organizations and to learn about their contribution to quality of care and patient safety improvements. : Guided by a model of HPWPs developed through an extensive literature review and synthesis, we conducted a series of interviews with key informants from five U.S. health care organizations that had been identified based on their exemplary use of HPWPs. We sought to explore the applicability of our model and learn whether and how HPWPs were related to quality and safety. All interviews were recorded, transcribed, and subjected to qualitative analysis. : In each of the five organizations, we found emphasis on all four HPWP subsystems in our conceptual model-engagement, staff acquisition/development, frontline empowerment, and leadership alignment/development. Although some HPWPs were common, there were also practices that were distinctive to a single organization. Our informants reported links between HPWPs and employee outcomes (e.g., turnover and higher satisfaction/engagement) and indicated that HPWPs made important contributions to system- and organization-level outcomes (e.g., improved recruitment, improved ability to address safety concerns, and lower turnover). : These case studies suggest that the systematic use of HPWPs may improve performance in health care organizations and provide examples of how HPWPs can impact quality and safety in health care. Further research is needed to specify

  1. Robust control systems theory and case studies

    2004-01-01

    "Robust Control Systems" gives a self-contained introduction to modern Control Theory. It thus adds a textbook to the existing research-oriented literature on Robust Control. The author lays emphasis on the modern aspects of the design of controllers with prescribed performance and robustness properties. Different to the classical engineering approach, a rigorous mathematical treatment is essential for the full understanding and applicability of the modern methods such as H2 or H8 control or methods based on the structured singular value µ. Nevertheless, no prior knowledge of Control Theory is required as the classical fundamentals are introduced within the first few chapters. Subsequently a large part of the text provides elementary examples and industrial case studies, which are developed in full detail to show how modern methods can be applied to advanced problems. They make intensive use of MATLAB, especially the Control Systems Toolbox and the µ-Analysis and Synthesis Toolbox.

    Full Text Available Support from top management and others is agreed to be an important factor in information systems success and failure, but little is written about how it has its effect and how it might be managed to a project's advantage. A recently developed conceptual framework is described. It covers the nature and forms of support, the way support affects project outcomes, the bases on which support is provided, and the strategies by which support may be managed. The framework is used to analyse a case study in several stages. At the end of the analysis of each stage, the framework's utility is assessed in terms of its explanatory value and the practical advice it suggests. Areas for further research are identified.

    Full Text Available For the last few decades there has been growing interest in making more integrated business decisions across larger segments of the logistic and distribution networks. Modern information technology is allowing this idea to be implemented, but there is need to develop a way of effective use of information technologies that support this business direction. In this paper a methodology to assist distribution networks reengineering with the aim of integrating logistic processes within the distribution supply chain has been promoted. The emphasis of methodology is on the business processes modelling and reengineering in the distribution network. Finally, this paper presents an oil company case study to illustrate how the methodology can be applied in practice.

    The LM2500+ industrial aeroderivative gas turbine, a 25% enhanced power derivative of the LM2500 gas turbine, recently completed its development test program during the period 5/96 - 10/96. Early in the engine program a Quality Function Deployment (QFD) process was used to determine customer needs for this project.The feedback obtained from the QFD process showed without doubt that gas turbine customers now emphasize product reliability and availability at the top of their needs. One area of development on the LM2500+ was to investigate the use of a brush seal as a means to reduce undesirable turbine cooling leakages within the turbine mid frame in order to enhance part life. This presentation presents a case study on the factors that went into evaluating a brush seal during engine test, test results, and the ultimate decision not to implement the brush seal for cost and other reasons.

    Full Text Available Background: With the publication of the Diagnostic and Statistical Manual, Third Edition (DSM-III in 1980, anxiety disorder was first identified as a diagnostic entity. A new theoretical approach regarding aetiology of anxiety disorders came next into the view, far from Freud’s psychoanalytical pathways. The consequences were new therapeutic guidelines, including psychopharmacotherapy and the use of behavioural and cognitive psychotherapy.Methods: The paper presents a case report study of a patient with social phobia. The use of analytical oriented psychotherapy, which helped to resolve Axis I symptoms, is described.Conclusions: In spite of new therapeutic guidelines there is still a certain population of patients with the need for psychoanalytical oriented psychotherapy. If we are to surrender the Freud’s legacy to the medical history, we will weaken psychiatry as a science and will narrow our therapeutic field.

    Full Text Available This study highlighted the importance of determining the impact that an ineffective mode of transport has on a firm’s transportation model and costs. The main focus of this study was to determine the logistics opportunity costs of using road transport within a mining firm. A case study approach was followed, as the investigation aimed to analyse a complex problem experienced by one company and present it in an easily understandable format. From the results of this study, it was apparent that the logistics opportunity costs associated with the mode of transport was substantial. This highlighted the need for firms to revise their choice of transport mode on a regular basis, as it has a major impact not only on their transportation costs, but also on their inventory holding and carbon emissions. The results also have implications for South Africa’s only freight railway, Transnet Freight Rail, which should not only focus on expanding its existing capacity, but also on improving its customer service delivery whilst containing tariff increases.

    Full Text Available Abstract Background Biological databases and pathway knowledgebases are proliferating rapidly. We are developing software tools for computer-aided hypothesis design and evaluation, and we would like our tools to take advantage of the information stored in these repositories. But before we can reliably use a pathway knowledgebase as a data source, we need to proofread it to ensure that it can fully support computer-aided information integration and inference. Results We design a series of logical tests to detect potential problems we might encounter using a particular knowledgebase, the Reactome database, with a particular computer-aided hypothesis evaluation tool, HyBrow. We develop an explicit formal language from the language implicit in the Reactome data format and specify a logic to evaluate models expressed using this language. We use the formalism of finite model theory in this work. We then use this logic to formulate tests for desirable properties (such as completeness, consistency, and well-formedness for pathways stored in Reactome. We apply these tests to the publicly available Reactome releases (releases 10 through 14 and compare the results, which highlight Reactome's steady improvement in terms of decreasing inconsistencies. We also investigate and discuss Reactome's potential for supporting computer-aided inference tools. Conclusion The case study described in this work demonstrates that it is possible to use our model theory based approach to identify problems one might encounter using a knowledgebase to support hypothesis evaluation tools. The methodology we use is general and is in no way restricted to the specific knowledgebase employed in this case study. Future application of this methodology will enable us to compare pathway resources with respect to the generic properties such resources will need to possess if they are to support automated reasoning.

    We undertook a study on a series of laryngeal sarcoidosis (LS), a very rare and often threatening localization to better specify laryngeal manifestations, sarcoidosis clinical expression and long-term follow-up. This was a retrospective case-control study. All LS patients from two French centers were included and compared to sarcoidosis patients without laryngeal localization with two controls for one patient. Twelve consecutive LS patients were recruited between 1993 and 2011. LS revealed sarcoidosis in eight cases (67%). The most common symptoms were hoarseness (77%), inspiratory dyspnea (38%) and dysphagia (38%). Epidemiological characterisics were not different. Extrapulmonary localizations were significantly more common in LS patients than in controls (92% vs. 54%, p=0.02), particularly lupus pernio (25% vs. 0%, p=0.03) and nasosinusal involvement (83% vs. 4%, p<0.01) while thoracic involvement was less frequent (58% vs 100%, p < 0.01). Treatment rates were higher in the LS group (92% vs. 58%, p=0.04), and treatment duration was longer (median: 81 vs. 13 months, p=0.04), with frequent long-term treatment (67%, N=8/12). Two patients underwent surgery. One patient needed temporary tracheostomy during the course of the disease; Remission rates were lower in LS patients (9% vs. 58% at 2 years p<0.01). Eventually, there was no death nor definitive tracheotomy. LS is a rare condition that is often associated to other loco-regional localizations. LS are often difficult to manage. Survival is good but may require a medico-surgical approach.

    The aim of this study was to describe integrative health (IH) coaching as developed in three different interventions offered through a major medical center, as a step toward further defining the field of health coaching. An organizational case study was conducted with document analysis and interviews. Interviewees were the first six IH coaches at Duke Integrative Medicine who provided 360 clients with individual and/or group coaching (two to 28 sessions) in a randomized clinical study and two work-site wellness programs. Qualitative analysis using the constant comparative method was conducted. Integrative health coaching is characterized by a process of self-discovery that informs goal setting and builds internal motivation by linking clients' goals to their values and sense of purpose. Time, commitment, and motivation are necessary in the IH coaching process. The underpinnings of IH coaching are distinct from the medical model, and the process is distinct from health education, executive coaching, and psychotherapy. Integrative health coaching fits well with the assumptions of integrative medicine and has a role in supporting behavior change. Copyright © 2011. Published by Elsevier Inc.

  14. Data Rescue Case Studies from the Cryosphere

    Fetterer, F. M.

    2017-12-01

    A simple definition of the cryosphere is "where the world is frozen", or where water takes the form of snow and ice. The cryosphere is shrinking as the Earth warms. Data, particularly old data, document this in often eye-opening fashion. A photograph of Alaska's Muir Glacier taken in 1902 next to one taken in 2005 has impact that a line graph of air temperature anomalies from a weather station can't match, even though temperature data are fundamental to climate research and to understanding the glacier retreat captured in the photographs. Whaling logbooks from the late 1800s, maps of sea ice shared internationally in the 1930s, and satellite images of the polar oceans from the 1960s are not as immediately thought-provoking as are glacier photographs, but when preserved and documented they provide a record of sea ice coverage that is more than 100 years long. We developed a data product from these and other sources that is used in meteorological reanalysis and to answer questions about ice in the Arctic prior to 1978, when commonly used satellite-data-derived sea ice records begin. Preserving glacier photographs and making them available online, and publishing a gridded sea ice data product that builds on the preservation work of others are examples of data rescue projects that benefit scientific research and mobilize knowledge. These and other case studies suggest that even absent secure funding and an organizational setting that supports data rescue, important data make the transition from someone's office to archived and online with metadata because scientists are impassioned about the data they collect and want others to be able to use these data. In these cases from the cryosphere, student interns, collaborations with librarians, and cooperation with colleagues in other data centers have made it possible to preserve data at low cost.

    Full Text Available Flooding is a consequence of the prevailing meteorological situation, the intensity and duration of precipitation, geomorphology, human activities over a geographical region and other factors. Floods result in damage and destruction of infrastructure and private property and, in some cases, in fatalities. Flash floods are sudden and quite localized in extend, characterized by excessive amounts of rainfall within a short period of time and are distinguished from other floods by their degree of severity. The broader knowledge concerning flash floods is useful for the better understanding of the underlying thermodynamic and dynamic mechanisms, as well as the associated physical processes. The wider understanding of flashfloods can form part of an integrated system for short and very short forecasting of these events. In the present study, the synoptic, dynamic and thermodynamic conditions during the development of a baroclinic depression which affected the area of Cyprus on 6 November 2005 are studied. The depression was associated with extreme weather phenomena, such as thunderstorms, a water spout and high precipitation accumulations. The results indicate the importance of the dynamic parameters in the system's development and the thermodynamic analysis has shown the convective potential of the atmosphere.

    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.

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

It was a single-case study that correlated degree of implementation with the of the result indicators surveillance. A logic model on this strategy and a matrix of indicators and judgments according to model components were drawn up. The degree of implementation was obtained from structure and process indicators and this was then correlated with result indicators, in a deductive approach based on intervention theory. Results: the structure approach presented superior results to the process in all evaluated components. This strategy was considered to have been partially implemented (75. 7%, however, the components of 'identification of deaths' (85.7%, 'epidemiological research' (88.1% and 'referral of proposals for promotion and health care and correction of official statistics' (95.8% were classified implemented. Regarding the relation of the degree of implantation of the surveillance and its results with the logical model, only one of the 17 indicators was considered inconsistent. Conclusions: this strategy was considered to have been partially implemented. The model of child mortality surveillance and its assessment were shown to be adequate for signaling the consistency of the interrelations between the activities proposed and the effects expected, and would be reproducible within other scenarios.

Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

  2. Anorexia in the Adolescence - case study

    Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

    Full Text Available Higher education students usually ask for more training based on case studies. This was addressed by designing a specific food safety module (24 hours in which students were shown how to predict microbiological risks in food products i.e. they were asked to determine product shelf-life according to product formulation, preservation methods and consumption habits using predictive microbiology tools. Working groups of four students first identified the main microbiological hazards associated with a specific product. To perform this task, they were given several documents including guides for good hygiene practices, reviews on microbiological hazards in the food sector, flow sheets, etc…  After three-hours of work, the working groups prepared and gave an oral presentation in front of their classmates and professors. This raised comments and discussion that allowed students to adjust their conclusions before beginning the next step of their work. This second step consisted in the evaluation of the safety risk associated with the two major microbiological hazards of the product studied, using predictive microbiology. Students then attended a general lecture on the different tools of predictive microbiology and tutorials (6 hours that made them familiar with the modelling of bacterial growth or inactivation. They applied these tools (9 hours to predict the shelf-life of the studied product according to various scenarios of preservation (refrigeration, water activity, concentration of salt or acid, modified atmosphere, etc… and/or consumption procedures (cooking. The module was concluded by oral presentations of each working group and included student evaluation (3 hours.

    2012-10-01

    This research documents and demonstrates viable approaches using existing materials, tools and technologies in owner-conducted deep energy retrofits (DERs). These retrofits are meant to reduce energy use by 70% or more, and include extensive upgrades to the building enclosure, heating, cooling and hot water equipment, and often incorporate appliance and lighting upgrades as well as the addition of renewable energy. In this report, 11 Northern California (IECC climate zone 3) DER case studies are described and analyzed in detail, including building diagnostic tests and end-use energy monitoring results. All projects recognized the need to improve the home and its systems approximately to current building code-levels, and then pursued deeper energy reductions through either enhanced technology/ building enclosure measures, or through occupant conservation efforts, both of which achieved impressive energy performance and reductions. The beyond-code incremental DER costs averaged $25,910 for the six homes where cost data were available. DERs were affordable when these incremental costs were financed as part of a remodel, averaging a $30 per month increase in the net-cost of home ownership.

  8. Environmental injustice: case studies from the South

    Cifuentes, Enrique; Frumkin, Howard

    2007-01-01

    We selected three case studies to illustrate environmental injustice issues in the South. These examples relate to migrant agricultural workers, the maquiladora industry and artisanal mining, while reviewing some of the major mechanisms involved, e.g. multinational corporations, the development of free trade zones, multilateral free trade agreements and the export of hazards. A series of strategies are discussed in order to address environmental injustice and health disparities that exist on a global scale. Some of the recommendations involve policy initiatives; others, such as research and mentorship, fall within the traditional domain of public health practice. In this paper, special attention is given to concerned environmental and occupational health professionals using evidence-based data for advocacy. For lasting changes to be made, however, stronger institutions and legislation are required. Those who have the 'right to know' about environmental injustice issues include communities of concern, workers' representatives and lawyers. Government officials and company officials may eventually work on the basis of conflict resolution, compensation and remediation, to quote some examples. Systematic approaches to protect both the environment and public health must be updated

    Full Text Available Hyperammonemia (HA is a metabolic emergency, and when not diagnosed and treated in a timely manner leads to severe neuro- logical damage and/ or death. HA may have multiple origins, but the EIM are one of the causes that should always be suspected. The objective of this work is to make a clinical description of the causes of HA in a sample of patients from the National Institute of Pediatrics (INP, to know the proportion of patients with HA in which could confirm the presence of an inborn error of metabolism (IEM. We found 72 patients with HA in the past 10 years, of whom 11 were patients already known to have an IEM and 61 with unknown cause; Of the latter, 46% of patients underwent metabolic studies (amino acids quantification, organic acids analysis and orotic acid quantification and in 14 cases (30% an IEM was diagnosed. The clinical symptoms most frequently observed were neurological (seizures, drowsiness, lethargy, irritability, developmental delay, and hypotonia stupor, etc., followed by digestive disturbances such as vomiting and refusal to eat. Urea cycle disorders, aminoacidopathies and organic acidemias were diagnosed, so the management and treatment of these should be known by the pediatricians, especially those dedicated to emergencies.

    Full Text Available 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.

    2013-04-18

    Leishmaniasis in many ways offers a unique vaccine case study. Two reasons for this are that leishmaniasis is a disease complex caused by several different species of parasite that are highly related, thus raising the possibility of developing a single vaccine to protect against multiple diseases. Another reason is the demonstration that a leishmaniasis vaccine may be used therapeutically as well as prophylactically. Although there is no registered human leishmaniasis vaccine today, immunization approaches using live or killed organisms, as well as defined vaccine candidates, have demonstrated at least some degree of efficacy in humans to prevent and to treat some forms of leishmaniasis, and there is a vigorous pipeline of candidates in development. Current approaches include using individual or combined antigens of the parasite or of salivary gland extract of the parasites' insect vector, administered with or without formulation in adjuvant. Animal data obtained with several vaccine candidates are promising and some have been or will be entered into clinical testing in the near future. There is sufficient scientific and epidemiological justification to continue to invest in the development of vaccines against leishmaniasis. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available The European refugee problem has grown dramatically in the last few months, putting a considerable amount of pressure on the European countries. Not only are they facing migrants from North Africa, but from the Middle East as well.In March 2011 the Arab Spring has reached Syria, causing a huge number of Syrians to flee their country and seek asylum in Turkey, and possibly going further to the EU. The refugees who fled Syria as well as those who are leaving North Africa (mostly the failed state of Libya are aiming to reach European soil, but Italy, Greece or Turkey is not ready to handle the amount of refugees. The cooperation of the Mediterranean countries and Europe has not been able to slow down the flow of refugees, and the Mediterranean and Aegean seas have become dangerous routes for the desperate migrants who attempt the sea-crossing. In my analysis I would like to highlight the role of the so-called elements of ‘soft power’ in the way of dealing with the refugee problem. According to my hypothesis, the issue can’t be successfully addressed using only the means of the ‘soft power’. No real solution for the crisis has been offered yet, and I would like to give case studies of the different ways of dealing with the problem – inside (Greece, Italy and outside (Turkey of the European Union.

    Turner syndrome (TS) is characterized by short stature, gonadal dysgenesis, and total or partial loss of X chromosome. A historical cohorts study of patients with TS≤18 years old followed up in public hospitals in Castilla y Leon was undertaken. Forty-two female patients were included (prenatal diagnosis 11.9%, neonatal diagnosis 14.3%) with current median age 11.9±4.2 years. Short stature was the reason for consultation in 87.1%. Total monosomy of X chromosome was present in 40.5%. The most frequently associated comorbidity was opthalmological (50%), with heart defects in 23.8%. Ninety-three percent were treated with growth hormone (GH), mean age at the beginning of treatment was 7.43±3.4 years and mean height standard deviation was -2.84±1.08. Final height was reached in 10 patients only (mean final height 151.47±6.09cm). Chronological age of puberty induction was 13.2±0.94 years (bone age 12.47±1.17 years). Short stature was an important clinical sign for the diagnosis of TS, accompanied in some cases by other findings, with good response to GH treatment. Copyright © 2016 Elsevier España, S.L.U.

  15. High Penetration Photovoltaic Case Study Report

    Energy Technology Data Exchange (ETDEWEB)

    Bank, J.; Mather, B.; Keller, J.; Coddington, M.

    2013-01-01

    Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

  16. Hybrid Risk Management Methodology: A Case Study

    2009-10-01

    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

  17. Guidelines for Conducting Positivist Case Study Research in Information Systems

    Directory of Open Access Journals (Sweden)

    Graeme Shanks

    2002-11-01

    Full Text Available The case study research approach is widely used in a number of different ways within the information systems community. This paper focuses on positivist, deductive case study research in information systems. It provides clear definitions of important concepts in positivist case study research and illustrates these with an example research study. A critical analysis of the conduct and outcomes of two recently published positivist case studies is reported. One is a multiple case study that validated concepts in a framework for viewpoint development in requirements definition. The other is a single case study that examined the role of social enablers in enterprise resource planning systems implementation. A number of guidelines for successfully undertaking positivist case study research are identified including developing a clear understanding of key concepts and assumptions within the positivist paradigm; providing clear and unambiguous definitions of the units and interactions when using any theory; carefully defining the boundary of the theory used in the case study; using hypotheses rather than propositions in the empirical testing of theory; using fuzzy or probabilistic propositions in recognising that reality can never be perfectly known; selecting case studies carefully, particularly single case studies; and recognising that generalisation from positivist, single case studies is inherently different from generalisation from single experiments. When properly undertaken, positivist, deductive case study research is a valuable research approach for information systems researchers, particularly when used within pluralist research programs that use a number of different research approaches from different paradigms.

    Full Text Available Change of venue is a remedy offered to a party, which in case of legitimate grounds for suspicion or public safety may require that proceedings belong to another court than the court first seized. But change of venue is not based on a case of material or territorial lack of jurisdiction of the court, taking into account exceptional circumstances or impartiality doubt regarding the case. Thus, article 140 of the Code of Civil Procedure stipulates the possible causes of change of venue, including further issues that will determine jurisdiction to hear by the courts of control.

    2016-01-01

    We conducted a case study of the Zimbabwe National AIDS Trust Fund ('AIDS Levy') as an approach to domestic government financing of the response to HIV and AIDS. Data came from three sources: a literature review, including a search for grey literature, review of government documents from the Zimbabwe National AIDS Council (NAC), and key informant interviews with representatives of the Zimbabwean government, civil society and international organizations. The literature search yielded 139 sources, and 20 key informants were interviewed. Established by legislation in 1999, the AIDS Levy entails a 3% income tax for individuals and 3% tax on profits of employers and trusts (which excluded the mining industry until 2015). It is managed by the parastatal NAC through a decentralized structure of AIDS Action Committees. Revenues increased from inception to 2006 through 2008, a period of economic instability and hyperinflation. Following dollarization in 2009, annual revenues continued to increase, reaching US$38.6 million in 2014. By policy, at least 50% of funds are used for purchase of antiretroviral medications. Other spending includes administration and capital costs, HIV prevention, and monitoring and evaluation. Several financial controls and auditing systems are in place. Key informants perceived the AIDS Levy as a 'homegrown' solution that provided country ownership and reduced dependence on donor funding, but called for further increased transparency, accountability, and reduced administrative costs, as well as recommended changes to increase revenue. The Zimbabwe AIDS Levy has generated substantial resources, recently over US$35 million per year, and signals an important commitment by Zimbabweans, which may have helped attract other donor resources. Many key informants considered the Zimbabwe AIDS Levy to be a best practice for other countries to follow.

    Gender equality and workforce diversity has recently been in the forefront of College discussions. Reasons for the difference between various groups may not be as they initially appeared. The results of comparing the outcome between two groups can sometimes be confounded and even reversed by an unrecognised third variable. This concept is known as Simpson's Paradox, and is illustrated here using a renowned case study on potential gender bias for acceptance to Graduate School at the University of California, Berkeley.  The investigation showed that males were 1.8 times more likely to be admitted to Graduate School than females in 1973. Initially it appeared that women were discriminated against in the selection process. However, when admissions were re-examined at individual Departments of the School, admission tended to be better for women than men in four of six Departments. This contradiction or paradox tells us that the association between admission and gender was dependent upon on Department.  The confounding effect of Department was defined by two characteristics. Firstly, a strong association between Department and admission: some Departments admitted much smaller percentages of applicants than others. Secondly, a strong association between Department and gender: females tended to apply to Departments with lower admission rates.  The explanation of differences between groups can be multifactorial. A search for possible confounders will assist in this understanding. This could apply whenever two groups initially appear to differ, but on closer analysis this difference is either unfounded, or even reversed by reference to a third, confounding variable. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Full Text Available The present study sets out to analyze the intertextual relation of Giovanni Boccaccio and Miguel Cervantes, focusing on the presence of the Decameron in the Exemplary Novels. After a first presentation, a description of the structure of the Decameron is attempted in order to detect potential influences on Cervantes regarding the art of relating, narrative procedures, discursive strategies and stylistic traits. Subsequently the study seeks to demonstrate how the birth of the Exemplary Novels depends on a personal reflection by Cervantes regarding the morphology of the prose of extensive imagination, womb of which the genre evolves in the course of the 16th century. Finally the direct correspondences between both raccolte di novella are cited.

Group of Hospitals and Grant Medical College, Mumbai is reported. Pemphigus vulgaris constituted the single largest group of 43 cases, followed by pemphigus foliaceus (25 cases and pemphigus vegetans (2 cases. Majority of the cases were seen in the age group of 21-60 years, with a slight male predominance. The youngest patient was 14 years while the eldest was aged 75 years. Mucosal involvement was seen in 31 cases of pemphigus vulgaris, as opposed to only 5 cases of pemphigus foliaceus. Flaccid bullae were present in 100% cases. Pruritus was complained of in 14 cases, though it was more common in pemphigus vegetans and vulgaris. Salient histopathological features of pemphigus vulgaris observed were (I intraepidermal suprabasal blisters (35 cases, (2 presence of acantholytic cells (40 cases, (3 "Row of tombstone appearance" (I8 cases and (4 acantholysis involving follicular sheath (20 cases.

    Five patients with radiation enterocolitis who were surgically treated are reported. The 5 patients had received irradiation therapy more than 5,000 rad for ginecologic malignancies. The period for the onset of symptoms of irradiation enteritis ranged from 8 months to 20 years however, 3 of them developed the symptoms within one year after irradiation therapy. Emergency surgery was carried out for bowel obstruction in 3 cases and for intestinal perforation in 2 cases. Bowel resection and primary anastomosis were performed by a one-step approach in 4 of them. Transient colostomy as preventive measure was added in 2 cases. It is very important for the one-step approach to resect the intestine at the healthy part far from the lesion of irradiation enteritis and to add a transient colostomy to prevent anastomolic insufficiency. Furthermore, suture material should be used less tissue reactive one. (author)

The sites of extramedullary dissemination reported in the literature are spleen, liver, lymph nodes, kidneys, thyroid gland, adrenal gland, ovary, tests, lung, pleura, pericardium, intestinal tract and skin. We report a case in which the myeloma was diagnosed after we discovered the presence of monoclonal plasma cells in the bronchoalveolar lavage fluid (BAL). Matherial and method: a case in which diagnosis was established from bronchoalveolar lavage (BAL) fluid demonstrating the presence of monoclonal plasma cells in Craiova Pneumology Departament. Analysis of BAL fluid for the presence of plasma cells and for cytoplasmic immunoglobulin DNA provides a noninvasive means of establishing the diagnosis. Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature.

    BACKGROUND:: stress in pregnancy is common and impacts negatively on women, infants and families. A number of factors contribute to high levels of stress in pregnancy, including financial concerns, marital discord, low support systems and low socio-economic status. OBJECTIVES:: the aim of this study was to evaluate stress anxiety levels and depressive symptoms among low risk women in an area in Ireland that was particularly impacted by the 2008 economic crisis. DESIGN:: a quantitative descriptive cross-sectional design was used. Data were collected using the Edinburgh Postnatal Depression Scale (EPDS), the Perceived Stress Scale and the State Trait Anxiety Inventory (STAI). Data was collected at a single time during the second trimester. SETTING:: this paper reports a case study of one maternity service in Ireland. Participants included low risk pregnant women who were attending the hospital clinic for routine antenatal care. RESULTS:: of 150 questionnaires distributed, 74 completed questionnaires were returned indicating a 49.3% return rate. Findings indicated high levels of stress, anxiety and depressive symptomatology among participants. There were no significant difference in mean EPDS score for different age groups (F4,69=2.48, P=0.052), living arrangements (F4,68=0.90, P=0.5) or usual occupation (F4,69=1.45, P=0.2). A score of ≥12 was taken as indicative of probable antenatal depression and 86.5% of participants responded with a score of 12 or above. PSS scores were also high and more than three quarters of respondents scored ≥15 (75.6%) and more than a third had scores ≥20 (35.1%), out of a total score of 40. There was a significant difference in mean PSS score between the different age groups (F4,69=3.60, P=0.010) but not for living arrangements or usual occupation. A STAI score of ≥39 was taken as indicative of antenatal anxiety, and 74.3% of participants responded with a score of 39 or above. There were no significant differences in mean STAI

    Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful

    Full Text Available Background: Mucocele is one of the most common benign soft tissue tumor present in the oral cavity. They are of two types - one is extravasation and second one is retention type but the majority are extravasation type. Aims: The objective is to determine various factors related to mucocele such as role of trauma due to nearby teeth, recurrence, duration, and to find out whether there is any role of psychological stress which initiates trauma like lip or cheek biting. Materials and Methods: 36 cases of mucocele diagnosed at the Department of the Oral Pathology, Govt. Dental College and Hospital, Ahmedabad, between 2004 and 2008 were reviewed. The clinical data were recorded and histopathologic diagnosis was made. Statistical Analysis Used: Data analysis tool, Microsoft Office Excel 2007. Results: A diagnosis of mucocele was established in 36 cases with male-to-female ratio of 1.77:1. Most common type was extravasation in 30 (83.33% cases. The peak age of occurrence was between 1st and 3rd decade. Lateral side of the lower labial mucosa was the most affected site in 34 (94.44% cases. The history of trauma appeared the major etiological factor seen in 28 (77.77% cases. Conclusion: We conclude that there was male predominance and they were more affected in 2nd and 3rd decade. The lateral side of lower labial mucosa was the commonest site and the trauma due to teeth or lip biting was the major etiological factor for the occurrence of the mucocele. The article highlights role of psychological stress in occurrence of mucocele. The reader should understand the importance of histopathology examination and should try to control the psychological stress in such mucocele patients.

    Full Text Available Delusional disorder-somatic (parasitosis type is a rare psychiatric disorder which poses a challenge to diagnostic and therapeutic skills. Pimozide, a highly specific dopamine blocker has shown promising results in the 3 cases illustrated here. These cases were seen over a period of 3 years. All the three patients believed that an insect has entered through the ear and is burrowing tracts/laying multiple eggs. They approached the ENT surgeons or neurosurgeon with a fear that their brain will be invaded. On psychiatric evaluation, no past or present history of major psychiatric illness was found. Premorbid personalities were well adjusted. Only for two patients, acute moderate stressors were detected. Delusions disappeared by the end of 2 wks but therapy was continued for 5 months.

    We analyze the clinical characteristics, the diagnostic criteria and the radiological aspects of 10 cases of Carcinomatous Lymphangitis. The quickly progressing exercise dyspnea and the constitutional syndrome were the most frequent symptoms. In nine patients, the tumor was previously unknown. The image methods (adbominal CAT and Echography) and the fibrobronchoscopic exam allowed a correct diagnosis. The most frequent neoplasia had a pulmonary origin and the most frequent histology was adenocarcinoma. The histological tests (bronchial and transbronchial biopsies) were more effective for the diagnosis than the cytological test (bronchoalveolar lavage, bronchoaspiration and bronchial brushing), although these were complemented. The radiology showed a reticulo-linear pattern in all the cases. The finding of macroscopic disorders in the fibrobronchoscopy, the presence of a local infiltration or a node/mass image in the thoracic radiography were highly suggestive of primary pulmonary neoplasia.

    Full Text Available The dissociative identity disorder (DID can be considered a rare disorder because of its seemingly low prevalence. However, in recent years it points to the possible underdiagnosis because its complexity and confusion at the time of differential diagnosis. On the other hand, the malingering of mental psychopathology can have a major socio-economic and legal impact, particularly important in this type of disorder, given the inability it generates and its complex diagnostic. This paper refers the case of a patient admitted to the short-term hospitalization unit of Dr. Rodríguez Lafora Hospital (Madrid with depressive symptoms. Then the patient seemed to become a TID case. The evaluation consisted of a psychological history and the application of the Structured Inventory of Malingered Symptoms (SIMS and the Millon Clinical Multiaxial Inventory (MCMI-II. The results showed an altered personality profile as well as likely malingered symptoms, what prevented us from a DID diagnosis. In view of the results, possible implications of this case for the clinical setting are discussed.

    2016-03-01

    Full Text Available Fetal tachyarrhythmia is unfeigned in most cases and occurs in about 1–3% of the total number of pregnancies. Most of it's kinds are ectopic intraatrial reductions. FA is usually diagnosed during the routine, starting from 18 weeks of gestation, ultrasound assessment of the fetal heart rate. Approximately 10% of fetuses with rhythm disorders are at high risk of sudden death. Supraventricular tachycardia and atrial fibrillation are the most common causes of sudden death, the same is observed for bradyarrhythmias: manifest sinus bradycardia (hypoxic genesis and expressed AV-blockade. The examination of all fetuses with arrhythmia was strongly recommended in cases of intrauterine cardiac arrest or death of the fetus in families. Arrhythmias which have been revealed during scheduled prenatal examination of the fetuses are in need of expert echocardiography assessment to determine the extent of possible pre- and postnatal risk of sudden death and the paril of arrhythmogenic cardiomyopathy formation. In case of identified life-threatening arrhythmia in fetus the pharmacological therapy, which greatly affects the favorable outcome is strongly recommended. It should be based on hemodynamic of pregnant and aimed to prevent the development of decompensation or arrhythmogenic cardiomyopathy.

  12. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Full Text Available Anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. Females are mostly affected, and the ratio is 3:1. Its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly and/or the human immunodeficiency virus. Diagnosis is based on clinical findings and anatomopathological tests. The treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. A retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. Six (54.5% were females and five (45.5% were males. The incidence was higher in the sixth decade, at the mean age of 54.45 years. The most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. Chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.Neoplasias do ânus correspondem de 2 a 4% dos tumores de intestino grosso, sendo predominante nas sétima e oitava décadas. A maior prevalência é em gênero feminino, com proporção de 3:1. O aumento da prevalência na população nos últimos anos provavelmente está relacionado ao número maior de pessoas com doenças sexualmente transmissíveis, principalmente o papilomavírus humano (tipos 16 e 18, mais comumente e/ou o vírus da imunodeficiência humana. O diagnóstico é feito a partir de achados clínicos somados ao exame anatomopatológico. O tratamento de escolha baseia-se na radioquimioterapia, sendo a cirurgia de resgate com amputação abdominoperineal utilizada para casos de recidiva ou persist

    The authors conducted a follow-up study on 243 Thorotrast-administered war-wounded ex-servicemen in 1975, after a lapse of 30 to 38 years from Thorotrast injections, and found 18 cases of malignant hepatic tumor, 15 cases of other malignant tumors, 2 cases of blood diseases, and 9 cases of liver cirrhosis in 224 cases who had been given Thorotrast intravascularly. The incidence of hepatic and other malignant tumors, blood diseases, and liver cirrhosis was significantly higher than in the controls. The total number of deaths in the Thorotrast-administered cases was also significantly higher than in the controls. In the remaining 19 cases who had been given Thorotrast by a route other than intravascularly, no fatal case related to Thorotrast administration was discovered. In the living cases, however, one sarcoma was observed to have developed at the site of the Thorotrast injection

    Anthony, Susan; Jack, Susan

    2009-06-01

    This paper is a report of an integrative review conducted to critically analyse the contemporary use of qualitative case study methodology in nursing research. Increasing complexity in health care and increasing use of case study in nursing research support the need for current examination of this methodology. In 2007, a search for case study research (published 2005-2007) indexed in the CINAHL, MEDLINE, EMBASE, PsychINFO, Sociological Abstracts and SCOPUS databases was conducted. A sample of 42 case study research papers met the inclusion criteria. Whittemore and Knafl's integrative review method guided the analysis. Confusion exists about the name, nature and use of case study. This methodology, including terminology and concepts, is often invisible in qualitative study titles and abstracts. Case study is an exclusive methodology and an adjunct to exploring particular aspects of phenomena under investigation in larger or mixed-methods studies. A high quality of case study exists in nursing research. Judicious selection and diligent application of literature review methods promote the development of nursing science. Case study is becoming entrenched in the nursing research lexicon as a well-accepted methodology for studying phenomena in health and social care, and its growing use warrants continued appraisal to promote nursing knowledge development. Attention to all case study elements, process and publication is important in promoting authenticity, methodological quality and visibility.

They occur all along the midline neuroaxis, from the nasion and occipital area down to the lumbar and sacral regions, most frequently in the lumbar and lumbosacral region. Case presentation Here we report a 5-year-old girl who presented with occasional headache. There were two dimples, one on the dorsal aspect of her head and another on her neck. Conclusion Dermal sinuses are almost always singular and the co-existence of double dermal sinuses has not been reported previously.

    Access and affordability to energy services determine the state of energy poverty; however, there is no widely applicable definition of energy poverty and no universal set of measures for its eradication exists. This paper offers a new definition and possible solution for decrease, and eventually eradication, of energy poverty for the specific case of Tajikistan. As eradication of energy poverty needs to go in hand with nature preservation and economic development, authors provide possible approach to decrease of energy poverty in Tajikistan while simultaneously preserving nature and boosting the local economy.

    Four disparate proposals for hospital programs, varying in their funding requirements and revenue-generating capacity, have been made to the chief executive officer (CEO) of a metropolitan nonprofit general hospital that has always prided itself on being responsive to community needs. Although the hospital faces severe financial pressures, the CEO has determined that one of the proposals can be supported. Three commentaries on this case discuss what ethical criteria should be considered in evaluating the four proposals, and what role the hospital ethics committee should play in the decision.

    Full Text Available The Tobacco Control Economics Project is a project that seeks to gather evidence on tobacco use and economics in southern Africa. It is a project of the University of Cape Town with support from the DataFirst repository based at the University of Cape Town. Its aim is to gather data that already exists, sometimes in digital form, frequently in offline records or in some cases paper records, and bring them together as an open resource. The project faces challenges of data gathering as well as permissions. Frequently data is or should be “available” in some form but control over the data is relinquished only unreluctantly. In many cases the legal standing of data is unclear. Many of the challenges relating to the bringing together of the data involve ascertaining what the legal standing of a dataset is or gaining permissions for its re-use. DataFirst is a longstanding data sharing infrastructure with professional and experienced data management staff. Challenges of ensuring continued funding and maintenance are similar to those of data infrastructures globally. The infrastructure meets international standards and provides leadership to other services and platforms in this space.

    To describe the processes involved in the selection of cases and controls, and the validation of case diagnosis, in a large case-control study on the association between myocardial infarction (MI) and oral contraceptives. Community case-control study in England, Scotland and Wales. Cases were women aged 16-44 with a diagnosis of MI. Controls were age and general practice matched women without a diagnosis of MI. The proportion of interviewed cases per number eligible was 19% (95% CI 12-26%) lower in England and Wales than in Scotland. The kappa score for agreement between three cardiologists on diagnostic categories of the potential cases was 0.52 overall ('moderate' agreement). For the 35 cases resubmitted for categorization, the kappa scores for agreement between the first and second classification for the two national committee cardiologists were 0.32 and 0.23 ('fair' agreement). Age matching of controls was better in Scotland than England and Wales, the proportion of the first choice controls being 14% (95% CI 8-19%) higher in Scotland. The mean time to complete a cluster of interviews (one case and four controls) was 36 days in Scotland and 63 days in England and Wales. Very close age-matching was achieved overall, although the process was more efficient in Scotland than in England and Wales. Some suggestions for improvement in the case validation process are made.

    2000-05-01

    To practice mammography diagnosis effectively, radiologists expect convenient access to well-organized and authoritative mammography related information, especially when there is case in question. The purpose of this study is to build infrastructural diagnosis support by incorporating various clinical information into a digital mammography case library, and allow user to search the library based on mammographic findings. The digital mammography case library has a three- tier architecture: (1) Back-end mammography databases integrate multimedia clinical information from various operational systems, including RIS and PACS. Cases are stored in a finding index database powered by an object-relational database with finding-coded reports, which are modeled around the ACR BI-RADS (American College of Radiology, Breast Imaging Report and Data System) standard. (2) The middle-end application controllers process application logic, such as user authorization, HTTP request handling, database connection and dynamic HTML page generation. (3) Web-based user interface is developed for authorized Intranet personnel to formulate query based on radiological finding (such as mass, calcification and architectural distortion), shape and assessment, using ACR BI-RADS specified lexicon. The case library so far has 103 cases selected from over 800 digital mammography studies carried out at the Mt. Zion hospital, UCSF, during an on-going digital telemammography project. We believe that an Intranet based digital mammography case library with mammographic finding search capability facilitates continuous medical education and online decision support, by providing exemplary study to compare with case in question.

    Jamińska-Gadomska, Paulina; Lipecki, Tomasz; Podgórski, Jerzy

    2018-01-01

    The paper presents results of CFD analysis performed to check the influence of wind action on a bell tower of a church. The geometry of the structure is quite complex therefore it is very hard to calculate wind load basing only on codes recommendations. The modelled geometry contains whole structure of the church including the bell tower. Results presented in this paper are focused on co-called "Venturi-effect" represented by the flow around the bell tower. CFD simulations were performed for two inflow wind directions of opposite senses. This led to two cases of converging and diverging walls of the bell tower in relation to the wind flow direction. Such analysis was performed to check if the wind speed increases between the walls of the bell tower.

    This paper reports a case of an 87-year-old female patient who was admitted for an emergency operation due to massive hemorrhage of an ulceration localized on a huge neck tumor. Post-interventional diagnosis indicated hidradenocarcinoma. Hidradenocarcinoma is a rare skin neoplasm. It can coincide with adenoma, may develop through its malignant transformation or develop as a malignant tumor from the beginning. It may be found in all dermal localizations. It may develop metastases or appear in the diffuse form. Surgical excision of the tumor was performed obtaining a surgical margin, completed with excision of local lymph nodes and multiple layer suturing. Due to lack of the patient's consent, she has not been qualified for adjuvant therapy. Control examination 6 and 12 months later showed no signs of local recurrence or lymph node metastasis. Surgical excision of apocrine hidradenocarcinoma with a surgical margin could present a good therapeutic effect in spite of lack of adjuvant therapy.

    Among the etiologies of anemia in the newborn, those related to mitochondrial cytopathies are rare. Pearson syndrome is mostly diagnosed during infancy and characterized by refractory sideroblastic anemia with vacuolization of marrow progenitor cells and exocrine pancreatic dysfunction. We describe two diagnosed cases of Pearson syndrome in the early neonatal period caused by severe macrocytic aregenerative anemia. Bone marrow aspiration revealed sideroblastic anemia and vacuolization of erythroblastic precursors. The diagnosis was confirmed by genetic analysis revealing a deletion in the mitochondrial DNA. These two newborns received monthly transfusions. Five other newborns suffering from Pearson syndrome with various clinical symptoms were found in literature. Pearson syndrome, rarely diagnosed in newborns, should be suspected in the presence of macrocytic aregenerative anemia and requires a bone marrow aspirate followed by a genetic analysis from a blood sample.

    Full Text Available Preface The extraordinary case of industrial pollution in Lake Orta was followed and documented by the Istituto Italiano di Idrobiologia from its very origin in 1926. Many papers were published regarding the effects of the pollution on chemistry and biology of the lake but they were scattered in various scientific journals and in a long time period. Now the time has come to draw the conclusions of our long work and the long history of the lake. We planned to publish a monographic volume, but technical reasons made it impossible to realise this project. The papers which could have formed the volume will be splitted into issues 60(1 and 60(2 of Journal of Limnology.

  19. Prayer and healing. A case study.

    Science.gov (United States)

    Hughes, C E

    1997-09-01

    This article examines the relationship between prayer and healing and its relationship to holistic health. The apparent healing that results from prayer mystifies researchers. Numerous theories may be offered as to the mechanism by which this healing occurs. The belief of the praying person in the power of the prayer itself may stimulate healing, as the placebo effect suggests. The relaxation response and the sense of self-efficacy gained through the act of praying may enhance the immune system. Despite these explanations of the mechanisms through which prayer promotes healing, there some-times exists a facet of prayer and healing that defies rational explanation and seems to suggest the existence of a higher power. A case is presented that explores assistance from a higher power as a potential explanation for the healing.

    Renal Artery Stenosis (RAS), is one of the causes of secondary hypertension; there are many causes of renal artery stenosis, as atherosclerosis of the renal artery which account for 90% of cases of RAS; fibromuscular dysplasia accounts for 10% of RAS. Various causes of thrombophilia either due congenital causes or acquired causes and can lead to RAS. Our patient was presented by acute attack of epistaxis and hypertension. Angiography of the Renal Arteries,are showed no sign of renal artery stenosis. However, the right kidney showed upper pole infarction, and the left kidney showed evidence of functional lower pole renal artery stenosis, although there is no anatomical stenosis detected in angiography. Work up for the cause of thrombophilia did not help in the diagnosis, which may be due to an undiscovered cause of thrombophilia

    This article will explore a clinical case study of a home visit carried out by the case manager nurse. In this case, we will discuss the dilemma of finding the balance between autonomy and beneficence from the perspective of principlist ethics, virtue ethics and the 'ethics of care'. The main conflict in this case study deals with all proposals are unsuitable and it is not necessary for a nurse to pay him a home visit, whereas for the healthcare system it is considered necessary. We could conclude that, during the home visit, the case manager aspires to achieve excellence, and throughout his clinical relationship with Francesc, searches for a series of virtues, respecting certain fundamental principles. In this way, the case managers ensure that Jaume's care is more humanised. The case has been anonymised and confidentiality maintained.

  4. An alternative approach for socio-hydrology: case study research

    Science.gov (United States)

    Mostert, Erik

    2018-01-01

    Currently the most popular approach in socio hydrology is to develop coupled human-water models. This article proposes an alternative approach, qualitative case study research, involving a systematic review of (1) the human activities affecting the hydrology in the case, (2) the main human actors, and (3) the main factors influencing the actors and their activities. Moreover, this article presents a case study of the Dommel Basin in Belgium and the Netherlands, and compares this with a coupled model of the Kissimmee Basin in Florida. In both basins a pendulum swing from water resources development and control to protection and restoration can be observed. The Dommel case study moreover points to the importance of institutional and financial arrangements, community values, and broader social, economic, and technical developments. These factors are missing from the Kissimmee model. Generally, case studies can result in a more complete understanding of individual cases than coupled models, and if the cases are selected carefully and compared with previous studies, it is possible to generalize on the basis of them. Case studies also offer more levers for management and facilitate interdisciplinary cooperation. Coupled models, on the other hand, can be used to generate possible explanations of past developments and quantitative scenarios for future developments. The article concludes that, given the limited attention they currently get and their potential benefits, case studies deserve more attention in socio-hydrology.

  5. Parody as re-use and parody as laughing: three exemplary cases of forgery in the musical theatre

    2016-11-01

    Full Text Available In the musical field 'parody' means first of all the borrowing of themes or whole compositions in the polyphonic practice (Missa parodia during the 15th-18th centuries: these re-use is absolutely serious and the new work can be understood without recognizing the parodied object. The paper focusses on the other meaning of the word: the parody as ironic citation or deformation of a preexistent style, thematic or harmonic idea, which come into being in the second half of the 18th century. This second use presupposes that the listener recognizes the parodic reference and knows the parodied object; it frequently occurres in the musical theatre, particularly in the comic opera: three interesting examples are in Verdi's Falstaff (parody of liturgy, Cornelius' Barbier von Bagdad(parody of belcanto and Britten's Midsummer Night's Dream (parody on the parody. Analysing these scores on the one hand, basing on Genette's fundamental essay Palimpsestes on the other hand, we try to show the mechanism of the musical parody and to classificate some different typologies.

  6. A H∞/μ solution for microvibration mitigation in satellites: A case study

    Preda, Valentin; Cieslak, Jérôme; Henry, David; Bennani, Samir; Falcoz, Alexandre

    2017-07-01

    The research work presented in this paper focuses on the development of a mixed active-passive microvibration mitigation solution capable of attenuating the transmitted vibrations generated by reaction wheels to a satellite structure. A representative benchmark provided by the European Space Agency (ESA) and Airbus Defence and Space, serves as a support for testing the proposed solution. The paper also covers modeling and design issues as well as a deep analysis of the solution within the H∞ / μ setting. Especially, an uncertainty modeling strategy is proposed to extract a Linear Fractional Transformation (LFT) model. Insight is naturally provided into various dynamical interactions between the plant elements such as bearing and isolator flexibility, gyroscopic effects, actuator dynamics and feedback-loop delays. The design of the mitigation solution is formulated into the H∞ / μ framework leading to a robust H∞ control strategy capable of achieving exemplary active attenuation performance across a wide range of reaction wheel speeds. A systematic analysis procedure based on the structured singular value μ is used to assess and demonstrate the robust stability and robust performance of the microvibration mitigation strategy. The proposed analysis method is also shown to be a powerful and reliable solution to identify worst-case scenarios without relying on traditional Monte Carlo campaigns. Time domain simulations based on a nonlinear high-fidelity industrial simulator are included as a validation step.

  7. Metallurgy of platinoids. Studies of industrial cases

    International Nuclear Information System (INIS)

    Blazy, P.; Jdid, E. A.

    2004-01-01

    The platinoids deposits, currently in exploitation, are often associated with dunitic and gabbroitic ultra-basic rocks containing copper, nickel and iron sulfides. The proportion of platinoids in these deposits is variable and requires generally an adaptation of the industrial processes for their recovery. Nevertheless, we can consider that the classical industrial way consists to treat the composite concentrates of copper-nickel-platinoids sulfides by melting/conversion operations following by hydrometallurgical operations of recovery of the basic metals Cu, Ni. These last ones concentrate the platinoids in leaching residues. In these residues, the platinoids are extracted and separated by hydrometallurgical ways including different techniques: dissolution, selective precipitation, distillation, solvent extraction, resins...The great variety of uses of platinoids makes their recycling difficult. The wastes are often too complex for being economically recycling. The environmental protection depends of the type of industry (metallurgical, chemical, mining). Some products present risks of fire and explosion. The toxicity often appears by superficial allergies and by serious troubles in case of ingestion of soluble salts. (O.M.)

    Lebrun, Marie-Andrée; Moreau, Patricia; McNally-Gagnon, Andréane; Mignault Goulet, Geneviève; Peretz, Isabelle

    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. Copyright © 2011 Elsevier Srl.

    Steele, S. J.; van der Vink, G.

    2002-05-01

    In April and May of 1979 an Anthrax epidemic broke out in the city of Sverdlovsk (now Ekaterinburg) in the former Soviet Union. Sixty-four people were reported to have died from the outbreak, although there is still debate concerning the actual number of victims. While Soviet officials initially attributed this outbreak to contaminated meat, the US Government maintained that the outbreak was due to a leakage from a biological weapons facility. We have created and implemented an undergraduate educational exercise based on the forensic analysis of this event. Students were provided case data of the victims, area satellite images and meteorological data. One goal of the exercise was for students to reconstruct the most probable scenario of events through valid inference based on the limited information and uncertainties associated with the data set. Another goal was to make students sensitive to issues of biological weapons and bioterrorism. The exercise was highly rated by students even before the events of September 11. There is a clear need to educate students, particularly in the sciences, to be aware of the signatures of terrorist activities. Evidence of terrorist activities is more likely to appear from unintended discoveries than from active intelligence gathering. We believe our national security can be enhanced by sensitizing those that monitor the natural environment to the signatures of terrorist activities through the types of educational exercises that we have developed.

    Full Text Available BACKGROUND Death occurring in apparently healthy individual in a case of natural death may arise suspicion of foul play. In these circumstances these cases may be subjected to medicolegal autopsy. The disease condition may be unknown to the individual and the relatives. This study was done to review the exact cause of death in sudden unexpected deaths, and enabling or assisting the legal authorities in detection of crime, to prove or disprove the foul play. Body mass index is the most frequently used indicator of body fatness. An attempt is made to find out whether there is any significant relationship between BMI and the risk for sudden cardiac death. MATERIALS AND METHODS Data of 50 cases of sudden unexpected death brought for medicolegal autopsy at govt. T.D. medical college Alappuzha in the year 2010 were studied and information were collected from the postmortem records. Data was entered in the proforma. The histopathological examination findings of relevant cases were studied. Analysis was done using MS EXCEL and Chi-square test was used as the test of significance in the comparison between two categorical variables. RESULTS In 50 cases, male predominance was observed and 88% were males in which 50% of males died of atherosclerotic occlusive coronary artery disease and among females 33% died of myocardial infarction. While considering the systemic distribution of cause of death, the cardiovascular system was found to be most commonly affected, 33 cases (66% followed by respiratory system 7 cases (14%. In 4 (8% cases gastrointestinal system was affected. In Two cases (4% central nervous system was affected and others were generalized infection, which constituted 2 cases.

  13. Architectural Symbols of a City - Case Study

    Poplatek, Jacek

    2017-10-01

    The identity of a city is understood as a collection of individual features, which give the city its individual character and distinguish it from other places; it undoubtedly constitutes a cultural value, which should be cherished. A city is made special thanks to its geographical location, landscape values, urban layout and - architecture. In the case of Sopot - a spa located on the Bay of Gdansk, the mosaic of the above-mentioned features has created a unique image of a seaside resort. Sopot architecture is distinguished by a complex of buildings dating back to the turn of the 20th century, which is the largest one in the country. The architecture of the city is dominated by eclectic influences, mainly Neo-gothic and Art-Nouveau, as well as early modernism; it is also possible to find examples of holiday architecture, with characteristic wooden verandas. The identity of a city and its image is not always permanent and unchanging in time. In the case of Sopot, only 5% of the existing buildings were damaged during the Second World War. However, the most important ones, characteristic for the city and located in its representative part, were destroyed. The war was followed by a period of economic stagnation and isolation from the free world, which lasted for almost 45 years. At that time there were no comprehensive revitalisation projects for this prestigious area of the city. The buildings constructed in the 1960s did not create an architecturally and spatially coherent urban tissue. The situation changed in 1989, when Poland regained its sovereignty. Since that time numerous investment projects have been carried out in Sopot, including the prestigious ones, located in the representative part of the city. This paper has been devoted to Sopot architecture - both historic and modern, the dominating architectural trends and the issues connected with the coexistence of “the old and the new”. The buildings characteristic for the city, historic and modern ones, which

    Full Text Available Assessment of monitoring networks of surface waters and determination of main and tributary stations is an important step in the development and improvement of these networks and in increasing their efficiency. In this study, Principal Components Analysis, PCA, and Factor Analysis, PFA, techniques were employed to evaluate water quality monitoring stations on theKaroonRiver. From among the monitoring stations available, eight were selected and the measured data from 2002 to 2004 were used to determine the main and tributary stations. Finally, results were validated employing the regression analysis technique. Based on the results obtained in this study, only one monitoring station (Bandemizan was identified as the main one among the eight stations selected. Also a similar study was conducted to determine main and tributary quality variables; however, the results of the KMO factor did not confirm using PFA and PCA for this part of study.

    Wind farm repowering involves the replacement of smaller and middle sized wind turbines, with state-of-the-art multi-megawatt turbines. In this paper, a detailed study of the repowering of a wind farm is presented, by computing the generated active power from existing wind turbines and the new ones. The active power generated with the wind turbines are totalized to obtain the yearly generated energy and analyzed, thus economic studies take the repowering cost into account too. (au)

Overall value obtained by the students in the subject of Case Studies also increased. In terms of the ability of explanation of the concept, the concept of truth and creativity, based on the ratings given by fellow students of average ability students were in either category, although there is less good, as are associated with the activity of the opinion and the quality of the opinions expressed.

  16. Case Study: Neglected Health Issues in Niger

    Directory of Open Access Journals (Sweden)

    Cameron Neylon

    2017-10-01

    Full Text Available The project “Problemes négligés du système de santé au Niger” focusses on a core set of often-neglected issues that nevertheless have an overall negative impact on health system effectiveness in Niger. For example, poor quality maternal health services result from challenges related to the midwifery profession and from pressures from addressing the effects of illegal termination of pregnancy. Overall health system governance is undermined by weak management of human resources and health information systems as well as problems related to decentralisation of health care provision and dependence on external funding for health projects. LASDEL applies a rapid assessment and qualitative research approach to working with patients and health care professionals to identify the scale and characteristics of these problems. The project goal is to develop an evidence base to support tackling these neglected issues. Développer des recherches sur les « problèmes négligés » dans la gouvernance de la santé, et sur cette base contribuer à des réformes des systèmes de santé permettant une meilleure qualité des soins pour les populations vulnérables. "Develop research on "neglected problems" in the provision of health systems, and through this work, contribute to health system reforms, that provide better quality of care for vulnerable populations." As can be seen above, many of these issues relate to reproductive health and more generally to health issues of disadvantaged groups. Some issues are neglected for political or social reasons meaning that they are not recognised or acknowledged and in some cases are criminalised. Therefore there are profound issues of participant privacy, protection and even safety for this project. Data sharing therefore requires thoughtful anonymisation and selection. The project group is Francophone with limited English language knowledge and the researchers and the context is largely in French. In common with

  17. Beyond Clinical Case Studies in Psychoanalysis: A Review of Psychoanalytic Empirical Single Case Studies Published in ISI-Ranked Journals

    Science.gov (United States)

    Meganck, Reitske; Inslegers, Ruth; Krivzov, Juri; Notaerts, Liza

    2017-01-01

    Single case studies are at the origin of both theory development and research in the field of psychoanalysis and psychotherapy. While clinical case studies are the hallmark of psychoanalytic theory and practice, their scientific value has been strongly criticized. To address problems with the subjective bias of retrospective therapist reports and uncontrollability of clinical case studies, systematic approaches to investigate psychotherapy process and outcome at the level of the single case have been developed. Such empirical case studies are also able to bridge the famous gap between academic research and clinical practice as they provide clinically relevant insights into how psychotherapy works. This study presents a review of psychoanalytic empirical case studies published in ISI-ranked journals and maps the characteristics of the study, therapist, patient en therapies that are investigated. Empirical case studies increased in quantity and quality (amount of information and systematization) over time. While future studies could pay more attention to providing contextual information on therapist characteristics and informed consent considerations, the available literature provides a basis to conduct meta-studies of single cases and as such contribute to knowledge aggregation.

    Scola, R.; Daughtrey, K.

    1980-01-01

    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.

    The research project 'KLIMAT' was 1.1.2009 to 31.8.2012. The main goal of this project was to develop a 'best practice' methodology for quantifying the carbon footprint of products with a focus on fruits, vegetables, dairy and meat products. The methodology was tested on six selected case products. One of these products was the carrot. The product was selected because it is a product with high sales volume, a large part of the production takes place in Norway, and it may be assumed to represent the root vegetables which are a very important group of vegetable products. Oestfold Research, in conjunction with BAMA and Gartnerhallen, collected the necessary data to conduct the study. Data came from a group of 13 producers with ties to Laagendalen that all products supplied to the Laagen Gulrot for processing and packing. The producers were voluntarily affiliated with an online reporting system for a variety of information, including information about resource use that were used in this study. Climate track of carrot packed in the cup was, according to the methodology that was developed 0.39 kg Co2-ekv/kg product delivered to the consumer, 0.44 kg Co2-ekv/kg consumed carrot. (Author)

  3. Management case study: Tampa Bay, Florida

    Morrison, Gerold; Greening, Holly; Yates, Kimberly K.; Wolanski, Eric; McLusky, Donald S.

    2011-01-01

    Tampa Bay, Florida, USA, is a shallow, subtropical estuary that experienced severe cultural eutrophication between the 1940s and 1980s, a period when the human population of its watershed quadrupled. In response, citizen action led to the formation of a public- and private-sector partnership (the Tampa Bay Estuary Program), which adopted a number of management objectives to support the restoration and protection of the bay’s living resources. These included numeric chlorophyll a and water-clarity targets, as well as long-term goals addressing the spatial extent of seagrasses and other selected habitat types, to support estuarine-dependent faunal guilds. Over the past three decades, nitrogen controls involving sources such as wastewater treatment plants, stormwater conveyance systems, fertilizer manufacturing and shipping operations, and power plants have been undertaken to meet these and other management objectives. Cumulatively, these controls have resulted in a 60% reduction in annual total nitrogen (TN) loads relative to earlier worse-case (latter 1970s) conditions. As a result, annual water-clarity and chlorophyll a targets are currently met in most years, and seagrass cover measured in 2008 was the highest recorded since 1950. Factors that have contributed to the observed improvements in Tampa Bay over the past several decades include the following: (1) Development of numeric, science-based water-quality targets to meet a long-term goal of restoring seagrass acreage to 1950s levels. Empirical and mechanistic models found that annual average chlorophyll a concentrations were a primary manageable factor affecting light attenuation. The models also quantified relationships between TN loads, chlorophyll a concentrations, light attenuation, and fluctuations in seagrass cover. The availability of long-term monitoring data, and a systematic process for using the data to evaluate the effectiveness of management actions, has allowed managers to track progress and

  6. Notion of Identification: A Philosophical Case Study

    Directory of Open Access Journals (Sweden)

    Arto Mutanen

    2016-09-01

    Full Text Available Human life should be good life in the real world which is not merely a function of objective facts but also a function of subjective factors like hopes, fears, interests, etc. Goodness, or excellence, is an ethical notion. The factors of good life cannot be identified solely by using the so-called factual (descriptive methods of identification. This means that the identification cannot be fully “objective” or fully “public”. Furthermore, there is a need for other methods of identification that also take into account certain “subjective” aspects of the object of identification. Following Jaakko Hintikka we call these methods contextual (perspectival methods of identification. Here ethics is not a set of ethical rules but rather the practical study of human life. How should we live our unique life? A philosophical-conceptual study is thus practical for this purpose. This is what Aristotle called practical wisdom (phronēsis.

    Case study research is a comprehensive method that incorporates multiple sources of data to provide detailed accounts of complex research phenomena in real-life contexts. However, current models of case study research do not particularly distinguish the unique contribution observation data can make. Observation methods have the potential to reach beyond other methods that rely largely or solely on self-report. This article describes the distinctive characteristics of case study observational research, a modified form of Yin's 2014 model of case study research the authors used in a study exploring interprofessional collaboration in primary care. In this approach, observation data are positioned as the central component of the research design. Case study observational research offers a promising approach for researchers in a wide range of health care settings seeking more complete understandings of complex topics, where contextual influences are of primary concern. Future research is needed to refine and evaluate the approach.

    Full Text Available 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   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.

  18. Rock stability analysis – A case study

    Full Text Available The problems of the stability of the mineral-bearing structure ST2 at 560 m of depth in the east zone of Bou-azzer mine disturbs the advance of the exploitation. The geological and structural study based on field observations and the analysis of core drilling shows the presence of altered and fractured diorite surmounted by cobalt mineralization. Based on the empirical methods of Barton (Q-system and Bieniawski (RMR the bed rock is classified as poor quality. The analytical study made it possible to dimension supporting by bow-pieces and bolting. The existence of several types of discontinuities (fault, diaclases and joints has made the realization of numerical simulation by the finite elements method very difficult. These discontinuities create a network of natural fractures which cut out the blocks in various forms likely to be detached or slip into the excavation, thus encouraging the infiltration of water creating pressure on the massif. The classical studies show their limits in practice for installation of supporting because they must take into account the characteristics of discontinuities. Hence a structural analysis of the massif is essential. The cracking survey of ST2 at 560 m of depth in the east zone of Bou-azzer mine at 560m of depth, and their processing by the DIPS software, showed the existence of three main families of discontinuity NW-SE with a dip of 75SW, NS subverticale and NE-SW with a dip of 57NW, and two families of minor joints NW-SE and NE-SW with successive dips of 40SW and 75SE. The analysis of fracturing surveys allowed us to evaluate the risks of falling blocks and the families of discontinuity responsible for them, and to limit the zones presenting a risk of slip and the families responsible for them. The importance of this study is of knowing how and where to put supporting to be opposed to the risk of fall and tilting of the blocks, caused by the network of discontinuities of the massif.
