  6. Formation of Apprenticeships in the Swedish Education System: Different Stakeholder Perspectives

    Directory of Open Access Journals (Sweden)

    Ingela Andersson


    Full Text Available The article explores the major features of the Swedish Government’s new initiative - a school based Upper Secondary Apprenticeship model. The analyses are guided by activity theory. The analysed texts are part of the parliamentary reformmaking process of the 2011 Upper Secondary School reform. The analyses unfold how the Government, the Swedish Trade Union Confederation (LO, and the Confederation of Swedish Enterprise (SN construct Upper Secondary Apprenticeship as an activity in the 21st century. The conclusion highlights how three traditional aspects of Swedish initial vocational education and training (IVET collide in the formation of Upper Secondary Apprenticeship – a curriculum of labour market based apprenticeships, a curriculum of school based IVET, and ill-defined curriculums of school based apprenticeships. The emerging Upper Secondary Apprenticeship curriculum foreshadows multifaceted educational trajectories where the learning targets, and not the responsibility for the student’s learning are displaced from the school to the workplace setting.

  9. Bridging the Gap between Work and Education in Vocational Education and Training: A study of Norwegian Apprenticeship Training Offices and E-portfolio Systems

    Directory of Open Access Journals (Sweden)

    Hæge Nore


    Full Text Available This article explores the effect that the use of e-portfolios initiated and organized by apprenticeship training offices has had on the learning processes and assessment practices of apprentices in Norwegian vocational education and training. Although these intermediate structures have the potential to bridge the gap between work and education, they seem to maintain a system of two parallel learning arenas. However, the article summarizes the innovative effects of these transformations as supportive structures for expansive apprenticeship. The study is based on data from a national project on quality assessment, which is supported by documentary evidence from e-portfolios in three different trades: plumbing, industrial mechanics and sales.

  20. Apprenticeship at CERN

    CERN Multimedia

    Staff Association


    In 1961, based on the finding that the evolution of the labour market created a growing need for qualified staff, a first agreement between the Republic and Canton of Geneva and CERN was signed. One of the objectives of this agreement was the vocational training of young electronics and physics laboratory technicians. CERN, an important stakeholder in the local economy, highlighted with this agreement its willingness to participate in the local social and economic development. The first apprentice arrived at CERN in 1965. In 1971, the apprenticeship centre was created; it now hosts over twenty apprentices in total and welcomes about six new apprentices each year. These apprenticeships are for young people aged between 15 and 21 years, coming from one of the CERN Member States, and having completed their mandatory education, e.g. 11th grade in Switzerland or 3ème in France. The training is divided between working time at CERN and one or two days per week at school (CFPT in Geneva for electronics or ...

  7. Cognitive apprenticeship in health sciences education: a qualitative review. (United States)

    Lyons, Kayley; McLaughlin, Jacqueline E; Khanova, Julia; Roth, Mary T


    Cognitive apprenticeship theory emphasizes the process of making expert thinking "visible" to students and fostering the cognitive and meta-cognitive processes required for expertise. The purpose of this review was to evaluate the use of cognitive apprenticeship theory with the primary aim of understanding how and to what extent the theory has been applied to the design, implementation, and analysis of education in the health sciences. The initial search yielded 149 articles, with 45 excluded because they contained the term "cognitive apprenticeship" only in reference list. The remaining 104 articles were categorized using a theory talk coding scheme. An in depth qualitative synthesis and review was conducted for the 26 articles falling into the major theory talk category. Application of cognitive apprenticeship theory tended to focus on the methods dimension (e.g., coaching, mentoring, scaffolding), with some consideration for the content and sociology dimensions. Cognitive apprenticeship was applied in various disciplines (e.g., nursing, medicine, veterinary) and educational settings (e.g., clinical, simulations, online). Health sciences education researchers often used cognitive apprenticeship to inform instructional design and instrument development. Major recommendations from the literature included consideration for contextual influences, providing faculty development, and expanding application of the theory to improve instructional design and student outcomes. This body of research provides critical insight into cognitive apprenticeship theory and extends our understanding of how to develop expert thinking in health sciences students. New research directions should apply the theory into additional aspects of health sciences educational research, such as classroom learning and interprofessional education.

    CERN Multimedia

    Adrian Billet


    CERN starting training apprentices in 1966 at the request of the Geneva authorities. The programme was consolidated with the opening of the training centre in 1971. In recent years CERN has taken on seven new technical apprentices each year (four in electronics, three in physics laboratory work), plus one or two administrative apprentices, such that there always are around 30 apprentices in total at CERN. The programme is highly regarded in Geneva by the authorities, industry, schools and young people, and contributes very positively to CERN's local image. Since the beginning 160 young people have now successfully completed their apprenticeships at CERN. Unlike some other employers, as a general rule CERN does not take on its ex-apprentices as staff; on completing their years at CERN the apprentices usually go on to higher education or are sought after by other employers.

    周雪梅; 于继超


    职业教育的历史实际上就是组织合作的历史。从组织合作的视域来考察职业教育的学徒制度,我们发现,无论是农业社会时期的行会学徒制、工业社会时期的集体商议学徒制,还是后工业社会以来兴起的现代学徒制,组织合作成为其主要特征。也就是说,组织合作犹如一条绵延的血脉隐藏在学徒制的肌体深处,虽然沉寂过却从未断裂过。20世纪80年代以来,这条血脉又迎来了其发展的勃勃生机。我们只有抓住了学徒制度这条血脉,才能真正把脉我国职业教育的发展走向。%The history of vocational education, in essence, is a history of organizational collaboration. Study on the apprenticeship system of vocational education from the perspective of organizational cooperation, we found that no matter the guild apprenticeship in agricultural social period, the collective negotiation apprenticeship in industrial social period, or the modern apprenticeship system in post-industrial society, organizational cooperation has al-ready become the main feature. Organizational cooperation, just like a blood vessel, is deeply hidden under the skin of apprenticeship, which used to be silence but has never stopped. Since 1980s, this blood vessel has begun to flourish again. Only if we seize the apprenticeship system, we could really grasp the development trends of voca-tional education in China.

    Davies, Paul


    This article advances the thinking of Thompson, Conaway and Dolan's "Undergraduate students' development of social, cultural, and human capital in a network research experience". Set against a background of change in the biosciences, and participation, it firstly explores ideas of what it means to be a scientist, then challenges the current view of the apprenticeship model of career trajectory, before going onto to consider the nature of participation in communities of practice and issues related to underrepresented minority groups in science. Central to this analysis is the place that the notion of habitus plays in thinking about shaping future scientists and the how this can both support, but also suppress, opportunities for individuals through a maintenance of the status quo.

  12. Describing the apprenticeship of chemists through the language of faculty scientists (United States)

    Skjold, Brandy Ann

    Attempts to bring authentic science into the K-16 classroom have led to the use of sociocultural theories of learning, particularly apprenticeship, to frame science education research. Science educators have brought apprenticeship to science classrooms and have brought students to research laboratories in order to gauge its benefits. The assumption is that these learning opportunities are representative of the actual apprenticeship of scientists. However, there have been no attempts in the literature to describe the apprenticeship of scientists using apprenticeship theory. Understanding what science apprenticeship looks like is a critical component of translating this experience into the classroom. This study sought to describe and analyze the apprenticeship of chemists through the talk of faculty scientists. It used Lave and Wenger’s (1991) theory of Legitimate Peripheral Participation as its framework, concentrating on describing the roles of the participants, the environment and the tasks in the apprenticeship, as per Barab, Squire and Dueber (2000). A total of nine chemistry faculty and teaching assistants were observed across 11 settings representing a range of learning experiences from introductory chemistry lectures to research laboratories. All settings were videotaped, focusing on the instructor. About 89 hours of video was taken, along with observer field notes. All videos were transcribed and transcriptions and field notes were analyzed qualitatively as a broad level discourse analysis. Findings suggest that learners are expected to know basic chemistry content and how to use basic research equipment before entering the research lab. These are taught extensively in classroom settings. However, students are also required to know how to use the literature base to inform their own research, though they were rarely exposed to this in the classrooms. In all settings, conflicts occurred when student under or over-estimated their role in the learning

    Franck Bernède


    Full Text Available This article explores the principles of musical discourse among the farmers of the Kathmandu Valley as revealed through the teaching of the dhimay drum. During ritual apprenticeship, the transmission of a corpus of musical compositions based on mimetic syllables that the discourse of authority of the masters expresses. Compositions played during religious processions originate from these syllables, which imitate the sounds of the drum. In addition, dhimay drum apprenticeship is inextricably linked to that of acrobatics, which includes the handling of a bamboo pole. This essay discusses the nature of this musical language in its traditional context, as well as its recent transformations in Newar society.

  17. [From apprenticeship to Nobel Prize: Henri Moissan's fabulous destiny]. (United States)

    Lafont, O


    Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

    Institute of Scientific and Technical Information of China (English)



    With a stable structure,the modern apprenticeship system in Germany is perfect and remarkable. From the point of view of institutional analysis,the core elements of the modern apprenticeship system in Germany are professional and vocational competence at the macro level. The core elements at the meso level are the principles of “consistent”and“community”. And the core ones at the micro level are the principles of“work-oriented”and“student is the center”. The biggest advantage of modern apprenticeship in Germany lies in the“state led and market driven”. China should learn from the successful experience of Germany, play the leading role of the government, set up a perfect management system of modern apprenticeship,build a win-win cooperation mechanism,and form a good quality assurance system in order to en-sure the implementation of the modern apprenticeship.%德国现代学徒制制度完善,结构稳定,成效显著。从制度分析的角度来看,德国现代学徒制宏观层次的核心要素是职业和职业能力,中观层次的核心要素是“一致”和“社团主义”原则,微观层次的核心要素是“行动导向”和“以学生为中心”原则。德国现代学徒制最大的优势在于“国家主导、市场驱动”。我国应借鉴德国的成功经验,发挥政府主导作用,建立完善的现代学徒制管理体制、构建多赢的现代学徒制合作机制、建设完善的现代学徒制保障制度,以保证现代学徒制的实施效果。

  1. Cognitive apprenticeship in clinical practice: can it stimulate learning in the opinion of students? (United States)

    Stalmeijer, Renée E; Dolmans, Diana H J M; Wolfhagen, Ineke H A P; Scherpbier, Albert J J A


    Learning in clinical practice can be characterised as situated learning because students learn by performing tasks and solving problems in an environment that reflects the multiple ways in which their knowledge will be put to use in their future professional practice. Collins et al. introduced cognitive apprenticeship as an instructional model for situated learning comprising six teaching methods to support learning: modelling, coaching, scaffolding, articulation, reflection and exploration. Another factor that is looked upon as conducive to learning in clinical practice is a positive learning climate. We explored students' experiences regarding the learning climate and whether the cognitive apprenticeship model fits students' experiences during clinical training. In focus group interviews, three groups of 6th-year medical students (N = 21) discussed vignettes representing the six teaching methods and the learning climate to explore the perceived occurrence of the teaching methods, related problems and possibilities for improvement. The students had experienced all six teaching methods during their clerkships. Modelling, coaching, and articulation were predominant, while scaffolding, reflection, and exploration were mainly experienced during longer clerkships and with one clinical teacher. The main problem was variability in usage of the methods, which was attributed to teachers' lack of time and formal training. The students proposed several ways to improve the application of the teaching methods. The results suggest that the cognitive apprenticeship model is a useful model for teaching strategies in undergraduate clinical training and a valuable basis for evaluation, feedback, self-assessment and faculty development of clinical teachers.

  2. Developing Teenage Youth's Science Identity Through an Astronomy Apprenticeship: Summative Evaluation Results (United States)

    Barros-Smith, R.; Porro, I.; Norland, E.


    We report on the results from the summative evaluation of the Youth Astronomy Apprenticeship (YAA) covering three years of implementation of the program. YAA is a year-long, out-of-school time initiative that connects urban teenage youth with astronomy as an effective way to promote scientific literacy and overall positive youth development. The program employs the strategies of a traditional apprenticeship model, common in crafts and trade guilds as well as in higher education. During the apprenticeship, youth develop knowledge and skills to create informal science education projects; through these projects they demonstrate their understanding of astronomy and use their communication skills to connect to general audiences. For some youth, participation extends across multiple years and their responsibilities for program implementation become multifaceted. Through exposing youth to astronomy investigations and providing opportunities to connect with audiences outside their program and communities, YAA expands scientific literacy to include assuming a science identity. We subscribe to the concept of science identity that describes personal ownership and integration of science into an individual's sense of self through processes of comprehension and personal meaning making. In the YAA context, science identity extends to and includes assuming an actual science advocacy role. Our methods for measuring the development of a science identity included assessments of a youth's perceived and actual understanding of science (cognitive construct), leadership in science (behavior construct), and commitment to science (affective construct).

    Full Text Available The primary purpose of this study is to determine the effect of a group guidance program to elementary 8th grade students’ views towards apprenticeship training. This study is a control group pre-test post-test experimental research. The research was conducted to students who were enrolled in an elementary school in Konya, Turkey. While research’s experimental group was constituted of 11 female and 14 male students (total: 25 students, control group was constituted of 11 female and 14 male students (total: 25 students. Vocational group guidance was conducted to experimental group for 9 weeks once a week. The views of experimental and control group students towards apprenticeship education were measured by Apprenticeship Education Evaluation Form-B (AEEF-B at pre-test post-test phases. In this research, applied vocational group guidance program includes views and behaviours which can be measured by Apprenticeship Education Evaluation Form-B. Group discussion and homework techniques were used to gain vocational views and behaviours in vocational group guidance. After analysis there have been found significant difference between experimental and control groups’ AEEF-B pre-test post-test average scores at 0.01 level. Findings showed that vocational group guidance method had a positive effect against negative ideas to apprenticeship education. In addition, vocational group guidance method has been found to be effective in changing 8th year elementary school students’ negative views towards apprenticeship education to positive views. This program is compatible as long as it is used in vocational guidance activities of 8th year elementary school students.

  4. The role of cognitive apprenticeship in learning science in a virtual world (United States)

    Ramdass, Darshanand


    This article extends the discussion started by Margaret Beier, Leslie Miller, and Shu Wang's (2012) paper, Science games and the development of possible selves. In this paper, I suggest that a theoretical framework based on a sociocultural theory of learning is critical in learning in a virtual environment. I will discuss relevant research on the application of various components of the sociocultural perspective of learning in classroom environments and the potential for applying them in virtual worlds. I propose that research in science education should explore the processes underlying cognitive apprenticeship and determine how these processes can be used in virtual environments to help students learn science successfully.

  8. The cognitive apprenticeship theory for the teaching of mathematics in an online 3D virtual environment (United States)

    Bouta, Hara; Paraskeva, Fotini


    Research spanning two decades shows that there is a continuing development of 3D virtual worlds and investment in such environments for educational purposes. Research stresses the need for these environments to be well-designed and for suitable pedagogies to be implemented in the teaching practice in order for these worlds to be fully effective. To this end, we propose a pedagogical framework based on the cognitive apprenticeship for deriving principles and guidelines to inform the design, development and use of a 3D virtual environment. This study examines how the use of a 3D virtual world facilitates the teaching of mathematics in primary education by combining design principles and guidelines based on the Cognitive Apprenticeship Theory and the teaching methods that this theory introduces. We focus specifically on 5th and 6th grade students' engagement (behavioral, affective and cognitive) while learning fractional concepts over a period of two class sessions. Quantitative and qualitative analyses indicate considerable improvement in the engagement of the students who participated in the experiment. This paper presents the findings regarding students' cognitive engagement in the process of comprehending basic fractional concepts - notoriously hard for students to master. The findings are encouraging and suggestions are made for further research.

  9. Development and Application of a Situated Apprenticeship Approach to Professional Development of Astronomy Instructors (United States)

    Prather, Edward E.; Brissenden, Gina

    Professional development for astronomy instructors largely focuses on enhancing their understanding of the limitations of professor-centered lectures while also increasing awareness and better implementation of learning strategies that promote a learner-centered classroom environment. Given how difficult it is to get instructors to implement well-developed and innovative teaching ideas, even when these instructors are supplied with significant and compelling education research data, one must wonder what is missing from the most commonly used professional development experiences. This article proposes a learner- centered approach to professional development for college instructors, which we call situated apprenticeship. This novel approach purposely goes beyond simple awareness building and conventional modeling, challenging instructors to actively engage themselves in practicing teaching strategies in an environment of peer review in which participants offer suggestions and critiques of each other's implementation. Through this learner-centered teaching and evaluation experience, instructors' preexisting conceptual and pedagogical understandings of a particular instructional strategy are brought forth and examined in an effort to promote a real change of practice that positively impacts both their core pedagogical content knowledge and their skills in successfully implementing these teaching strategies. We believe that the adoption of our situated apprenticeship approach for professional development will increase the frequency and success of college instructors' implementation of research-validated instructional strategies for interactive learning.

  12. The Effect of Cognitive Apprenticeship-Based Professional Development on Teacher Self-Efficacy of Science Teaching, Motivation, Knowledge Calibration, and Perceptions of Inquiry-Based Teaching (United States)

    Peters-Burton, Erin E.; Merz, Sydney A.; Ramirez, Erin M.; Saroughi, Maryam


    This study investigated the effects of a 1-year professional development (PD) based on a cognitive apprenticeship model of research experiences on inservice teacher self-efficacy of science teaching, motivation, knowledge calibration, and perceptions of inquiry of 19 secondary earth science and biology teachers. The PD facilitator, who serves a dual role as a scientist and teacher educator, utilized a cognitive apprenticeship model to shape both scientific thinking and inquiry instruction with 19 inservice teachers. Results indicated that inservice teachers changed their perceptions of inquiry and maintained high self-efficacy throughout all phases of the study. However, teachers refrained from making long-term changes in their cognitive strategy instruction. Implications provide a fuller picture of teacher learning during a RET program, supported with inquiry instruction and the implications of cognitive apprenticeships in offering authentic science research experiences with minimal laboratory resources.

  13. Hydro Ottawa's apprenticeship program : building the foundation of our business and future

    Energy Technology Data Exchange (ETDEWEB)

    Jefferies, L. [Hydro Ottawa Ltd., Ottawa, ON (Canada)


    Hydro Ottawa is a local distribution company (LDC) with a workforce of 551 people and 127 line maintainers. Apprentices are required due to the physically demanding nature of power line maintenance as well as due to the fact that the utility's workforce is aging. Hydro Ottawa's apprenticeship program was designed as a long-term investment in the utility's future. The cost of the program is offset by a reduced need for hiring contractors. Experienced trades staff are re-deployed to fill many other positions within the utility. The program includes constant monitoring of new recruits during probation to ensure that potential employees are suited to the job. Training resources are optimized to create a safe, focused environment that focuses on the development of core skills. The recruitment process has a strong marketing focus and has the following 5 stages: (1) resume screening, (2) college testing, (3) an interview, (4) a heights and confined space test, and (5) a physical fitness test and medical. The first year of the program involves dedicated training, a boot camp, bi-weekly individual reviews, and testing at a facility. Formal trades training is also conducted. The second year of the program includes a yearly site rotation and attendance at a formal trade school. The third year includes a 4 month stint on an emergency response team. figs.

  14. Building Science Identity in Disadvantaged Teenage Girls using an Apprenticeship Model (United States)

    Pettit, E. C.; Conner, L.; Tzou, C.


    Expeditionary science differs from laboratory science in that expeditionary science teams conduct investigations in conditions that are often physically and socially, as well as intellectually, challenging. Team members live in close quarters for extended periods of time, team building and leadership affect the scientific process, and research tools are limited to what is available on site. Girls on Ice is an expeditionary science experience primarily for disadvantaged girls; it fully immerses girls in a mini scientific expedition to study alpine, glacierized environments. In addition to mentoring the girls through conducting their own scientific research, we encourage awareness and discussion of different sociocultural perspectives on the relation between the natural world, science, and society. The experience aligns closely with the apprenticeship model of learning, which can be effective in enhancing identification with science. Using a mixed-methods approach, we show that the Girls on Ice model helps girls (1) increase their interest and engagement in science and build a stronger science identity, (2) develop confidence, importantly they develop a combined physical and intellectual confidence; (3) engage in authentic scientific thinking, including critical thinking and problem solving; and (4) enhance leadership self-confidence. We discuss these results in a learning sciences framework, which posits that learning is inseparable from the social and physical contexts in which it takes place.

  1. Investigating the effects of cognitive apprenticeship-based instructional coaching on science teaching efficacy beliefs (United States)

    Cooper, Teo O. H.

    The overall purpose of this collected papers dissertation was to examine the utility of a cognitive apprenticeship-based instructional coaching (CAIC) model for improving the science teaching efficacy beliefs (STEB) of preservice and inservice elementary teachers. Many of these teachers perceive science as a difficult subject and feel inadequately prepared to teach it. However, teacher efficacy beliefs have been noted as the strongest indicator of teacher quality, the variable most highly correlated with student achievement outcomes. The literature is scarce on strong, evidence-based theoretical models for improving STEB. This dissertation is comprised of two studies. STUDY #1 was a sequential explanatory mixed-methods study investigating the impact of a reformed CAIC elementary science methods course on the STEB of 26 preservice teachers. Data were collected using the Science Teaching Efficacy Belief Instrument (STEBI-B) and from six post-course interviews. A statistically significant increase in STEB was observed in the quantitative strand. The qualitative data suggested that the preservice teachers perceived all of the CAIC methods as influential, but the significance of each method depended on their unique needs and abilities. STUDY #2 was a participatory action research case study exploring the utility of a CAIC professional development program for improving the STEB of five Bahamian inservice teachers and their competency in implementing an inquiry-based curriculum. Data were collected from pre- and post-interviews and two focus group interviews. Overall, the inservice teachers perceived the intervention as highly effective. The scaffolding and coaching were the CAIC methods portrayed as most influential in developing their STEB, highlighting the importance of interpersonal relationship aspects in successful instructional coaching programs. The teachers also described the CAIC approach as integral in supporting their learning to implement the new inquiry

  3. The effectiveness of apprenticeship training: A within-track comparison of workplace-based and school-based vocational training in Hungary. (United States)

    Horn, Dániel


    Although apprenticeship training has been praised for its effectiveness in easing the transition of non-college-bound students from school to work, most studies rely on cross-country or cross-track comparisons. This study compares apprenticeship training students with non-apprentices within educational track in a relatively uncoordinated and decentralized institutional setting. Using a rich database and a unique set of observable individual-level characteristics as well as local labor market fixed effects to control for the potential selection bias, the results show that there are no significant differences in employment opportunities between apprentices and non-apprentices within just a year after graduation. This might be due to the failure of the Hungarian firms to enhance the skills of apprentices and thus increase their chances of entering the labor market compared to their school-trained peers. However, some immediate positive effect of apprenticeship training within sub-populations is apparent, which are likely to be the result of screening.

  5. Global Economic Crisis and Career Aspirations among ‘Okada’ Riders in Nigeria: The Influence of Apprenticeship Skills Training

    Directory of Open Access Journals (Sweden)

    Oluranti I. Ogunrinola


    Full Text Available In spite of their usefulness as fast movers of passengers and goods in urban traffic congestion, the motor-cycle taxis have been noted for high rate of road traffic crashes inflicting injuries to many and death in some cases. Thus, a number of operators are in the occupation for other purposes rather than making it a lifetime career. This study is therefore aimed at examining such other purposes and future career aspirations of riders. It is also aimed at testing the hypothesis of the probabilistic migration model as propounded by Todaro. The data for the study is from a survey of 777 okada riders in two states of South West Nigeria. Using binary logit regression approach, the determinants of career choice among respondents are examined. The findings of the study shows employment as okada riders are for raising start-up capital in most cases, and that education, current earnings level and apprenticeship skills training among others are statistically significant variables affecting career aspiration among the respondents. Provision of commensurate employment for the educated youths and relaxing capital constraints for those with previous skills training are some of the policy implications of findings.

  6. Using M-learning as a Means to Promote Self-direction and Engagement in Apprenticeship Theoretical Lessons

    Directory of Open Access Journals (Sweden)

    Alan O'Donnell


    Full Text Available An exploratory case study was carried out to investigate if the use of mobile phones as a tool for learning could address concerns over the current learning of the carpentry and joinery apprentices in the Dublin Institute of Technology. The concerns are regarding a lack of learner self-direction and engagement with the learning content. A high level of mobile phone usage was apparent among the apprentice cohort. It was decided to take advantage of the potential learning opportunity offered by mobile technologies to promote the learning and engagement of the apprentices. Towards this goal, a compatible resource was developed, hosting presentations, course content, videos and questions. This study explored the views of the learners in the carpentry and joinery trade apprenticeship and their attitudes towards developing an m-learning resource. The aim of the research was to explore if this m-learning resource encouraged self-direction and engagement. Further objectives of this study were to establish a start point for further research projects and resource development.

  9. Situated cognition and cognitive apprenticeship: a model for teaching and learning clinical skills in a technologically rich and authentic learning environment. (United States)

    Woolley, Norman N; Jarvis, Yvonne


    The acquisition of a range of diverse clinical skills is a central feature of the pre-registration nursing curriculum. Prior to exposure to clinical practice, it is essential that learners have the opportunity to practise and develop such skills in a safe and controlled environment under the direction and supervision of clinical experts. However, the competing demands of the HE nursing curriculum coupled with an increased number of learners have resulted in a reduced emphasis on traditional apprenticeship learning. This paper presents an alternative model for clinical skills teaching that draws upon the principles of cognitive apprenticeship [Collins, A., Brown, J.S., Newman, S., 1989. Cognitive Apprenticeship: teaching the crafts of reading, writing and mathematics. In: Resnick, L.B. (Ed.) Knowing. Learning and Instruction: Essays in Honor of Robert Glaser. Lawrence Erlbaum Associates, New Jersey, pp. 453-494] and situated cognition within a technologically rich and authentic learning environment. It will show how high quality DVD materials illustrating clinical skills performed by expert practitioners have been produced and used in conjunction with CCTV and digital recording technologies to support learning within a pedagogic framework appropriate to skills acquisition. It is argued that this model not only better prepares the student for the time they will spend in the practice setting, but also lays the foundation for the development of a clinically competent practitioner with the requisite physical and cognitive skills who is fit for purpose [UKCC, 1999. Fitness for Practice: The UKCC Commission for Nursing and Midwifery Education. United Kingdom Central Council for Nursing Midwifery and Health Visiting, London].

  10. Learning through inter- and intradisciplinary problem solving: using cognitive apprenticeship to analyse doctor-to-doctor consultation. (United States)

    Pimmer, Christoph; Pachler, Norbert; Nierle, Julia; Genewein, Urs


    Today's healthcare can be characterised by the increasing importance of specialisation that requires cooperation across disciplines and specialities. In view of the number of educational programmes for interdisciplinary cooperation, surprisingly little is known on how learning arises from interdisciplinary work. In order to analyse the learning and teaching practices of interdisciplinary cooperation, a multiple case study research focused on how consults, i.e., doctor-to-doctor consultations between medical doctors from different disciplines were carried out: semi-structured interviews with doctors of all levels of seniority from two hospital sites in Switzerland were conducted. Starting with a priori constructs based on the 'methods' underpinning cognitive apprenticeship (CA), the transcribed interviews were analysed according to the principles of qualitative content analysis. The research contributes to three debates: (1) socio-cognitive and situated learning, (2) intra- and interdisciplinary learning in clinical settings, and (3), more generally, to cooperation and problem solving. Patient cases, which necessitate the cooperation of doctors in consults across boundaries of clinical specialisms, trigger intra- as well as interdisciplinary learning and offer numerous and varied opportunities for learning by requesting doctors as well as for on-call doctors, in particular those in residence. The relevance of consults for learning can also be verified from the perspective of CA which is commonly used by experts, albeit in varying forms, degrees of frequency and quality, and valued by learners. Through data analysis a model for collaborative problem-solving and help-seeking was developed which shows the interplay of pedagogical 'methods' of CA in informal clinical learning contexts.

    Directory of Open Access Journals (Sweden)

    Huasheng Zhu


    Full Text Available Knowledge learning and diffusion have long been discussed in the literature on the dynamics of industrial clusters, but recent literature provides little evidence for how different actors serve as knowledge brokers in the upgrading process of apprentice-based clusters, and does not dynamically consider how to preserve the sustainability of these clusters. This paper uses empirical evidence from an antique furniture manufacturing cluster in Xianyou, Fujian Province, in southeastern China, to examine the growth trajectory of the knowledge learning system of an antique furniture manufacturing cluster. It appears that the apprentice-based learning system is crucial during early stages of the cluster evolution, but later becomes complemented and relatively substituted by the role of both local governments and focal outsiders. This finding addresses the context of economic transformation and provides empirical insights into knowledge acquisition in apprentice-based clusters to question the rationality based on European and North American cases, and to provide a broader perspective for policy makers to trigger and sustain the development of apprentice-based clusters.

  17. “Too busy to think, too tired to learn” - the attrition of the apprenticeship model of surgical training in the United Kingdom

    Directory of Open Access Journals (Sweden)

    Andrea Kelly


    Full Text Available Abstract: This article examines the notion of apprenticeship as experienced by trainee surgeons within the modern NHS, and attempts to demonstrate some unintended consequences of managerial target setting upon the training process. It argues that this situation is made more critical by the lack of explicit standards and curriculum by which trainees may assess their progress, and also that the potential grafting of behaviourist competence-based training models onto older notions of apprenticeship will be inadequate to meet the need for an holistic account of the development of professional practice. Alternative theoretical perspectives are examined, in particular social accounts of shared and collaborative expertise such as Lave and Wenger’s “community of practice” and Vygotsky’s thinking on the “zone of proximal development” with its emphasis on a highly active pedagogic role for both mentor and peers. A parallel is also suggested with Leder’s work on therapeutic discourse, in the sense that both patient and trainee actively construct shared interpretative modes with the doctor-mentor. These accounts challenge the traditional model of medical education which assumes a linear hierarchy of learning, effectively ignoring the cyclic nature of surgical development, and the mutual learning needs of “new comers” and “old-timers”. In order to initiate the modelling of surgical development, it is suggested that: • a dynamic and non-linear view of progress is required; • the link between formal structured training and opportunistic learning “on the job” is crucial; • assessment strategies are needed that promote, rather than hinder, the learning that derives from reflective practice.

    challenges and opportunities of delivering on-line and virtual content to apprentices in a Polytechnic institution. Due to the current financial recession, apprentices are going back to academia in order to update their skills, but these potential students are not willing to leave their workplace or their personal lives behind to study. In this context on-line delivery represents an opportunity to provide access to content without leaving the work environment. However, in order to be successful in providing on-line materials for apprentices, polytechnics around the world are facing two challenges: How to transform hands-on Learning skills to online Learning material, and how to provide a rich-engaging environment for this group of learners. But not only the learner expectations should be taken when designing on-line learning. Instructors play also a crucial role in this endeavor, as Web 2.0 technologies offer the instructor an entirely new role in teaching: that of a facilitator. In order to analyze apprenticeship students’ on-line learning, 57 on-line surveys were distributed among a group of students registered for on-line apprenticeship programs. The paper presents research findings and a comparison of these with a what the literature states regarding the new generation of learners and their use of technologies, and the behavior (learning preferences, learning styles, use of IT presented by the research sample. Innovative opportunities for learning at the workplace (such as recommendations and future areas of research are suggested.

  18. Situated learning - beyond apprenticeship and social constructionism

    DEFF Research Database (Denmark)

    Christensen, Gerd


    The aim of this paper is to discuss the theoretical and philosophical fundament of Jean Lave & Etienne Wenger’s theory of ’situated learning’. In Denmark, the theory has been categorized under as different paradigms as a theory of learning as ‘apprenticeship’ and as ‘social constructionism......’. This may seem as a theoretical discussion without any implications for an actual practice. But, as it will be argued in the paper, the perception of the theory has fundamental consequences for how it is considered to contribute to the understanding of learning and to analyses of learning in an actual...... context. The paper can, thus, be considered as not only a contribution to a narrow discussion of ‘situated learning’, but also to the wider discussion of how to conceptualize ‘learning’ as such. In addition, the paper discusses some of the analytical perspectives, which are at stake in some of the other...

    Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

  20. The Role of System Thinking Development and Experiential Learning on Enterprise Transformation (United States)

    Lopez, Gabriel

    The recent economic downturn has had global repercussions in all businesses alike. Competition is fierce and a survival of the fittest model is always present; fast delivery times and innovative designs ultimately translate into the enterprises' bottom line. In such market conditions, enterprises have to find ways to develop and train their workforce in a manner that enhances the innovative capabilities of the enterprise. Additionally, if companies are to stay competitive, they have to ensure critical skills in their workforce are transferred from generation to generation. This study builds on recent research on system-thinking development via experiential learning methodologies. First, a conceptual framework model was developed. This conceptual model captures a methodology to construct a system-thinking apprenticeship program suitable for system engineers. Secondly, a survey of system engineering professionals was conducted in order to assess and refine the proposed conceptual model. This dissertation captures the findings of the conceptual model and the implications of the study for enterprises and for system engineering organizations.

    Full Text Available Dans cet article, nous constatons qu'une activité ne peut pas être définie uniquement par sa forme effective et les connaissances du domaine visé qui sont mises en jeu. Nous proposons de définir une activité par les connaissances du domaine d'apprentissage mises en jeu, par sa forme mais également en ce qu'elle peut influer l'état de connaissance de l'apprenant et les moyens que l'on a de vérifier cet impact. Nous proposons ici nos résultats de recherche pluridisciplinaires menés autour de la spécification et la modélisation d'activités pédagogiques dans le domaine de la lecture dans le but de construire un environnement de suivi de l'apprenant. Nous présentons la méthodologie de travail pratiquée dans l'équipe, la structure des spécifications d'activités, les modèles computationnels déduits et finalement leur mise en œuvre dans un environnement de suivi de l'apprenant.In this article, we note that an activity cannot be only defined by its effective form as well as the targeted subject's learning processes engaged in performing the task. An activity is hereby described as the knowledge of the subject to be learned, in the means of its structure as well as how it can impact student's state of knowledge, and how this influence can be regulated. Results of interdisciplinary research, concerning the specification and modeling of teaching activities for the apprenticeship of reading, are presented here. The results aim at giving more insights on the subject, in order to build an adaptive learning environment that keeps track of student's learning achievements and process. This article is structured in several parts: presentation of the team's research methodology, structure of activity requirements, computational models deduced, and finally their implementation in an adaptive learning environment.

  15. Model Based Reasoning by Introductory Students When Analyzing Earth Systems and Societal Challenges (United States)

    Holder, L. N.; Herbert, B. E.


    Understanding how students use their conceptual models to reason about societal challenges involving societal issues such as natural hazard risk assessment, environmental policy and management, and energy resources can improve instructional activity design that directly impacts student motivation and literacy. To address this question, we created four laboratory exercises for an introductory physical geology course at Texas A&M University that engages students in authentic scientific practices by using real world problems and issues that affect societies based on the theory of situated cognition. Our case-study design allows us to investigate the various ways that students utilize model based reasoning to identify and propose solutions to societally relevant issues. In each of the four interventions, approximately 60 students in three sections of introductory physical geology were expected to represent and evaluate scientific data, make evidence-based claims about the data trends, use those claims to express conceptual models, and use their models to analyze societal challenges. Throughout each step of the laboratory exercise students were asked to justify their claims, models, and data representations using evidence and through the use of argumentation with peers. Cognitive apprenticeship was the foundation for instruction used to scaffold students so that in the first exercise they are given a partially completed model and in the last exercise students are asked to generate a conceptual model on their own. Student artifacts, including representation of earth systems, representation of scientific data, verbal and written explanations of models and scientific arguments, and written solutions to specific societal issues or environmental problems surrounding earth systems, were analyzed through the use of a rubric that modeled authentic expertise and students were sorted into three categories. Written artifacts were examined to identify student argumentation and

    Walter, Igor; Gomide, Fernando [Universidade Estadual de Campinas (UNICAMP), SP (Brazil). Faculdade de Engenharia Eletrica e de Computacao. Dept. de Engenharia de Computacao e Automacao Industrial; Takahashi, Leticia; Correia, Paulo de Barros [Universidade Estadual de Campinas (UNICAMP), SP (Brazil). Faculdade de Engenharia Mecanica


    Auctions are used in a myriad of economic transactions through different trading environments. This work addresses simulation and implementation of power auction strategies based on an actual case, namely, first auction of existent energy recently completed by the Brazilian electricity sector. Auctions provide formal methods to allocate resources based on competition, where sellers and buyers aim to maximize their benefit. The goal of this work is to study automatic learning of bidding strategies for an agent playing in a power auction. The agent learns bidding strategies from data and information commonly available during electronic auctions. The intelligent power auction agent learning approach is based on neural dynamic programming, a scheme that combines dynamic programming and neural networks techniques. Evidences suggest that the neural dynamic programming is an effective learning approach for power auction learning agents. More specifically, it is shown that Q-learning mechanism is a valuable approach to learn sub-optimal bidding policies in real time when using neural network for function approximation. (author)

  14. Development of habits through apprenticeship in a community: DHAC theoretical framework of physics teacher preparation

    CERN Document Server

    Etkina, Eugenia; Vokos, Stamatis


    The DHAC framework builds on the contemporary understanding of teacher preparation and strives to provide a better understanding of the process of learning to teach physics. Extant literature on teacher preparation suggests that pre-service teachers learn best when they are immersed in a community that allows them to develop dispositions, knowledge and practical skills and share with the community a strong vision of what good teaching means. However, despite having developed the requisite dispositions, knowledge and skills in pursuing the shared vision of good teaching, the professional demands on a teacher's time are so great out of and so complex during class time that if every decision requires multiple considerations and deliberations with oneself, the productive decisions might not materialize. We therefore argue that the missing link between intentional decision-making and actual teaching practice are the teacher's habits (spontaneous responses to situational cues). Teachers unavoidably develop habits w...

  17. Democratic Citizenship – A Conditioned Apprenticeship. A Call for Destabilisation of Democracy in Education

    Directory of Open Access Journals (Sweden)

    Maria Olson


    Full Text Available We live in times when the search for a citizenship education that can transcend national, ethnical and cultural borders is an important part of educational policy. In times of increased pressure by the European Union on its nation states to provide for nation-transcending democracy, this question becomes crucial for national policymaking in Europe. In this text, Swedish education policy will be taken as a case in point in order to shed light on how this question is being handled in this particular national policy setting. It is argued that the policy’s citizen fostering agenda tends to be counterproductive in the sense that it is still situated in national notions of the relationship between democracy and education, which tend to exclude certain individuals and groups of people on an age-related and (ethno cultural basis. It is further argued that these excluding features can be related to educational ideas about socialisation. The aim of this text is underlined by suggesting a different way of framing democracy and democratic citizenship education: to increase the potential of education as regards the renewal of democracy and democratic citizenship.

  3. Multi-media Case Methods in Pre-service Science Education: Enabling an Apprenticeship for Praxis (United States)

    Bencze, Larry; Hewitt, Jim; Pedretti, Erminia


    In recent years, teacher educators have looked to case methods as one means of bridging the theory-practice gap in university-based pre-service programs. This paper explores how case methods may be used to foster habits of praxis - that is, critical, reflective practice - that enable beginning teachers to adapt to the many diverse contexts they may encounter in the field. Our research used qualitative ethnographic methods to determine the efficacy of a case method designed to encourage critical analysis of a Year 8 science Optics lesson. Results suggest student teachers: (1) understood an associated analytical framework; (2) effectively analysed curriculum and pedagogy; and (3) exercised prudence in their assessment of the case. These findings tentatively indicate emerging habits of praxis. Notwithstanding such gains, we encourage designers of case-based curricula to: ensure case authenticity, protect subjects from critique and use multi-media case methods in conjunction with other approaches to promote habits of praxis.

  8. Staging Death, Translating Death, Rehearsing Death: A Photographer’s Apprenticeship in Dying

    Directory of Open Access Journals (Sweden)

    Daniela Fargione


    Full Text Available The preponderance of death imagery in the mass media and a recent interest of photography in the practice of death suggest the need to reevaluate our approach to death and dying, especially when violence is involved. This essay is a case study of History of Violence, Claudio Cravero's last photographic project. His collection of "portraits" reproduce apparent dead bodies, mostly attacked in their own domestic spheres, but neither the perpetrator of death (a mysterious murderer?, nor the weapon used (an omnipresent knife, should be considered as main focal points of the artist's inquiry. The undoubtful protagonist of these photographs, instead, is the light, that illuminates fear: not of death itself, rather of the obnoxious indifference to it, as the result of generalized death imagery saturation.     The staged apparent death displayed in Cravero's photographs serve both as a memento mori and as a strategy to come to terms with the idea of death. In short, it is an apprentship in dying through a domesticating translation practice. Eventually, Cravero's History of Violence offers a complex reflection on the interplay between each individual story and macrolevel social History, thus providing some hypotheses of where violence and death fit in that odd geometry of time and space that we call life.

  12. Advanced nursing apprenticeship program: a strategy for retention of experienced critical care nurses. (United States)

    Coleman, B


    Most hospitals are frantically planning recruitment strategies to attract new nurses for intensive care units. The direct cost associated with orientation of one of these nurses is estimated at greater than $2000, plus 6 months' to 1 year's salary per nurse. An interim strategy of using registered nurses to fill a full-time position for 1 year can cost upwards of $75,000 a year. Germane to the acclimatization of these nurses to the intensive care unit is the nurturing role of experienced nurses during the orientation and in assuring continuity of high-quality patient care. By virtue of their position, experienced nurses also model leadership behavior, and they are exposed to many day-to-day stresses that may leave them frustrated and feeling a lack of accomplishment. These factors, coupled with the scarcity of educational opportunities designed specifically for experienced nurses and a perceived absence of challenges, can lead to burnout. In this article I will describe an innovation in practice that uses the clinical nurse specialist role to stimulate and challenge experienced nurses. The program taught, supported, and nurtured unit-based change initiated by experienced nurses.

The "gas molecular model" will be introduced to explain the mechanism cooling by the expansion engine and the Joule-Thomson expansion valve. These two expansion processes are normally used in helium refrigeration systems to cool the process gas to cryogenic temperature. The reverse Carnot cycle will be discussed in detail as an ideal refrigeration cycle. First the fundamental process of liquefaction and refrigeration cycles will be discussed, and then the practical helium refrigeration system. The process flow of the system and the key components; -compressor, expander, and heat exchanger- will be discussed. As an example of an actual refrigeration system, we will use the cryogenic system for the KEKB superconducting RF cavity. We will also discuss the liquid helium distribution system, which is very important, especially for the cryogenic systems used in accelerator applications. 1 Principles of Cooling and Fundamental Cooling Cycle 2 Expansion engine, Joule-Thomson expansion, kinetic molecular theory, and enthalpy 3 Liquefaction Systems 4 Refrigeration Systems 5 Practical helium liquefier/refrigeration system 6 Cryogenic System for TRISTAN Superconducting RF Cavity

    Technology has now progressed to the point that intelligent systems are replacing humans in the decision making processes as well as aiding in the solution of very complex problems. In many cases intelligent systems are already outperforming human activities. Artificial neural networks are not only capable of learning how to classify patterns, such images or sequence of events, but they can also effectively model complex nonlinear systems. Their ability to classify sequences of events is probably more popular in industrial applications where there is an inherent need to model nonlinear system

  13. Systemic darwinism. (United States)

    Winther, Rasmus Grønfeldt


    Darwin's 19th century evolutionary theory of descent with modification through natural selection opened up a multidimensional and integrative conceptual space for biology. We explore three dimensions of this space: explanatory pattern, levels of selection, and degree of difference among units of the same type. Each dimension is defined by a respective pair of poles: law and narrative explanation, organismic and hierarchical selection, and variational and essentialist thinking. As a consequence of conceptual debates in the 20th century biological sciences, the poles of each pair came to be seen as mutually exclusive opposites. A significant amount of 21st century research focuses on systems (e.g., genomic, cellular, organismic, and ecological/global). Systemic Darwinism is emerging in this context. It follows a "compositional paradigm" according to which complex systems and their hierarchical networks of parts are the focus of biological investigation. Through the investigation of systems, Systemic Darwinism promises to reintegrate each dimension of Darwin's original logical space. Moreover, this ideally and potentially unified theory of biological ontology coordinates and integrates a plurality of mathematical biological theories (e.g., self-organization/structure, cladistics/history, and evolutionary genetics/function). Integrative Systemic Darwinism requires communal articulation from a plurality of perspectives. Although it is more general than these, it draws on previous advances in Systems Theory, Systems Biology, and Hierarchy Theory. Systemic Darwinism would greatly further bioengineering research and would provide a significantly deeper and more critical understanding of biological reality.

    Based on the concept of a physical system, this book offers a new philosophical interpretation of classical mechanics and the Special Theory of Relativity. According to Belkind's view the role of physical theory is to describe the motions of the parts of a physical system in relation to the motions of the whole. This approach provides a new perspective into the foundations of physical theory, where motions of parts and wholes of physical systems are taken to be fundamental, prior to spacetime, material properties and laws of motion. He defends this claim with a constructive project, deriving b

  3. Bubble systems

    CERN Document Server

    Avdeev, Alexander A


    This monograph presents a systematic analysis of bubble system mathematics, using the mechanics of two-phase systems in non-equilibrium as the scope of analysis. The author introduces the thermodynamic foundations of bubble systems, ranging from the fundamental starting points to current research challenges. This book addresses a range of topics, including description methods of multi-phase systems, boundary and initial conditions as well as coupling requirements at the phase boundary. Moreover, it presents a detailed study of the basic problems of bubble dynamics in a liquid mass: growth (dynamically and thermally controlled), collapse, bubble pulsations, bubble rise and breakup. Special emphasis is placed on bubble dynamics in turbulent flows. The analysis results are used to write integral equations governing the rate of vapor generation (condensation) in non-equilibrium flows, thus creating a basis for solving a number of practical problems. This book is the first to present a comprehensive theory of boil...

    The ongoing rapid expansion of the Internet greatly increases the necessity of effective recommender systems for filtering the abundant information. Extensive research for recommender systems is conducted by a broad range of communities including social and computer scientists, physicists, and interdisciplinary researchers. Despite substantial theoretical and practical achievements, unification and comparison of different approaches are lacking, which impedes further advances. In this article, we review recent developments in recommender systems and discuss the major challenges. We compare and evaluate available algorithms and examine their roles in the future developments. In addition to algorithms, physical aspects are described to illustrate macroscopic behavior of recommender systems. Potential impacts and future directions are discussed. We emphasize that recommendation has a great scientific depth and combines diverse research fields which makes it of interests for physicists as well as interdisciplinar...

  7. Nanorobotic Systems

    Directory of Open Access Journals (Sweden)

    Lixin Dong


    Full Text Available Two strategies towards the realization of nanotechnology have been presented, i.e., top-down and bottom up. The former one is mainly based on nanofabrication and includes technologies such as nano-lithography, nano-imprint, and etching. Presently, they are still 2D fabrication processes with low resolution. The later one is an assembly-based technique. At present, it includes such items as self-assembly, dip-pen lithography, and directed self-assembly. These techniques can generate regular nano patterns in large scales. To fabricate 3D complex nano devices there are still no effective ways by so far. Here we show our effort on the development of a nano laboratory, a prototype nanomanufacturing system, based on nanorobotic manipulations. In which, we take a hybrid strategy as shown in Fig. 1. In this system, nano fabrication and nano assembly can be performed in an arbitrary order to construct nano building blocks and finally nano devices. The most important feature in this system is that the products can be fed back into the system to shrink the system part by part leading to nanorobots. Property characterization can be performed in each intermediate process. Due to the nanorobotic manipulation system, dynamic measurement can be performed rather than conventional static observations.

  8. System-of-Systems Complexity

    Directory of Open Access Journals (Sweden)

    Hermann Kopetz


    Full Text Available The global availability of communication services makes it possible to interconnect independently developed systems, called constituent systems, to provide new synergistic services and more efficient economic processes. The characteristics of these new Systems-of-Systems are qualitatively different from the classic monolithic systems. In the first part of this presentation we elaborate on these differences, particularly with respect to the autonomy of the constituent systems, to dependability, continuous evolution, and emergence. In the second part we look at a SoS from the point of view of cognitive complexity. Cognitive complexity is seen as a relation between a model of an SoS and the observer. In order to understand the behavior of a large SoS we have to generate models of adequate simplicity, i.e, of a cognitive complexity that can be handled by the limited capabilities of the human mind. We will discuss the importance of properly specifying and placing the relied-upon message interfaces between the constituent systems that form an open SoS and discuss simplification strategies that help to reduce the cognitive complexity.

    Energy Technology Data Exchange (ETDEWEB)

    Graham, R.L.


    The Systems Studies Activity had two objectives: (1) to investigate nontechnical barriers to the deployment of biomass production and supply systems and (2) to enhance and extend existing systems models of bioenergy supply and use. For the first objective, the Activity focused on existing bioenergy markets. Four projects were undertaken: a comparative analysis of bioenergy in Sweden and Austria; a one-day workshop on nontechnical barriers jointly supported by the Production Systems Activity; the development and testing of a framework for analyzing barriers and drivers to bioenergy markets; and surveys of wood pellet users in Sweden, Austria and the US. For the second objective, two projects were undertaken. First, the Activity worked with the Integrated BioEnergy Systems (TBS) Activity of TEA Bioenergy Task XIII to enhance the BioEnergy Assessment Model (BEAM). This model is documented in the final report of the IBS Activity. The Systems Studies Activity contributed to enhancing the feedstock portion of the model by developing a coherent set of willow, poplar, and switchgrass production modules relevant to both the US and the UK. The Activity also developed a pretreatment module for switchgrass. Second, the Activity sponsored a three-day workshop on modeling bioenergy systems with the objectives of providing an overview of the types of models used to evaluate bioenergy and promoting communication among bioenergy modelers. There were nine guest speakers addressing different types of models used to evaluate different aspects of bioenergy, ranging from technoeconomic models based on the ASPEN software to linear programming models to develop feedstock supply curves for the US. The papers from this workshop have been submitted to Biomass and Bioenergy and are under editorial review.

  10. Systemic trauma. (United States)

    Goldsmith, Rachel E; Martin, Christina Gamache; Smith, Carly Parnitzke


    Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

  2. System Dynamics (United States)

    Morecroft, John

    System dynamics is an approach for thinking about and simulating situations and organisations of all kinds and sizes by visualising how the elements fit together, interact and change over time. This chapter, written by John Morecroft, describes modern system dynamics which retains the fundamentals developed in the 1950s by Jay W. Forrester of the MIT Sloan School of Management. It looks at feedback loops and time delays that affect system behaviour in a non-linear way, and illustrates how dynamic behaviour depends upon feedback loop structures. It also recognises improvements as part of the ongoing process of managing a situation in order to achieve goals. Significantly it recognises the importance of context, and practitioner skills. Feedback systems thinking views problems and solutions as being intertwined. The main concepts and tools: feedback structure and behaviour, causal loop diagrams, dynamics, are practically illustrated in a wide variety of contexts from a hot water shower through to a symphony orchestra and the practical application of the approach is described through several real examples of its use for strategic planning and evaluation.

    Systemic sclerosis is a challenging and heterogeneous disease due to the involvement of multiple organs and the high impact on morbidity and quality of life. Lung fibrosis, pulmonary arterial hypertension, and cardiac manifestations are main causes of systemic sclerosis-related deaths. In addition, patients suffer from a various range of co-morbidities such as malnutrition, depression, osteoporosis, malignancies, which are increased in these patients and have to be identified and treated. Early assessment of organ damage is a key to therapeutic success. The discovery of pathogenic autoantibodies combined with increased evidence of effective immunosuppressive and vasoactive treatment strategies are major developments in the therapy of the disease. At present, several clinical studies are ongoing and some of the biological therapies are promising.

    Full Text Available We intended to present in this work an approximation between Gilles Deleuze’s philosophy and Hume’s. Firstly we will show that Deleuze, in his reading of Hume, emphasizes empiricism’s importance for philosophy, though an empiricism distinct from the one offer by the philosophical tradition. We will further intend to show that these two authors share a common set of perspectives, namely, that thinking happens in response to an event, that “relation” is the instance that prompts thinking, and that the latter presents himself as an experience.Pretendemos neste artigo apresentar uma aproximação entre as filosofias de Gilles Deleuze e de David Hume. Primeiramente mostraremos que, em sua leitura de Hume, Deleuze destaca a importância do empirismo para a filosofia, mas um empirismo diferenciado da interpretação feita pela tradição filosófica. Posteriormente, procuraremos mostrar que ambos os autores partilham perspectivas comuns, a saber, que o pensar se dá a partir de um acontecimento, que a instância propiciadora do pensar é a “relação”, e que o mesmo se apresenta como uma experimentação. Por fim, faremos uma breve apresentação de alguns pontos divergentes entre os filósofos, destacando o significado do empirismo para a filosofia da imanência de Deleuze.

  12. The Observatory-Camping: a place of posible apprenticeship to the education and popularization of the Astronomy (United States)

    Navone, H. D.; Gastaud, C.; Pattini, N.; Aquilano, R.

    The development of Astronomy in the Educations area presents limitations as: poor equipment, trouble in managing space and time, difficulty to make experiences. The sky contaminations in the city, because of the luminosity, make the astronomical observation just impossible. But, the formal education has a wonderful media for the Astronomy: camping; this activity is very close to physical education. The proposal is the transformation of camping in "observatory-camping", to introduce astronomical concepts by the exploration of the sky. The methodology for this job is the observation of the sky by the eyes, first, and then making use of binoculars and a telescope, far from urban centres. Finally, this experience has place in the Planta de Campamentos N° 7502 (Máximo Paz, Santa Fe), which belongs to Ministerio de Educación de la Provincia de Santa Fe. FULL TEXT IN SPANISH

  13. Conceptual Model of Physics Teacher Preparation: Developing Habits of Mind and Practice through Apprenticeship in a Community (United States)

    Etkina, Eugenia


    This talk will describe a conceptual framework aimed at providing a better understanding of the process of physics teacher formation. Literature on teacher preparation suggests that pre-service teachers (PSTs) learn best when they are immersed in a community, which shares a common vision of good teaching and helps PSTs develop requisite knowledge, skills, and dispositions consistent with that vision. However, often due to the time pressures and complexities of classroom environment a teacher cannot afford multiple considerations and deliberations with oneself before every decision. We therefore suggest that good teacher preparation programs should, in addition to the knowledge, skills and dispositions, strive to develop in PSTs productive habits. We group these habits into habits of mind, habits of practice and habits of maintenance and improvement. I will present examples of those and provide suggestions on how to structure physics teacher preparation program to help future physics teachers develop these habits.

  2. Curriculum development for an advanced regional anesthesia education program: one institution's experience from apprenticeship to comprehensive teaching. (United States)

    Ouanes, Jean-Pierre P; Schwengel, Deborah; Mathur, Vineesh; Ahmed, Omar I; Hanna, Marie N


    Results of recent attitude survey studies suggest that most practicing physicians are inadequately treating postoperative pain. Residents in anesthesia are confident in performing lumbar epidural and spinal anesthesia, but many are not confident in performing the blocks with which they have the least exposure. Changes need to be made in the training processes to a comprehensive model that prepares residents to perform a wider array of blocks in postgraduate practice. Here, we describe one institution's approach to creating a standardized, advanced regional anesthesia curriculum for residents that follows the six core competencies of the ACGME. Residents received training in anatomy dissection, ultrasound-guided regional anesthesia, traditional nerve stimulation techniques, problem-based learning and simulation sessions, oral board presentation sessions, and journal club sessions. Residents kept a detailed log for their use of peripheral nerve block procedures. We have now redesigned and implemented an advanced regional anesthesia program within our institution to provide residents with experience in regional anesthesia at a competent level. Resident's knowledge in regional anesthesia did improve after the first year of implementation as reflected in improvements between the pre- and post-tests. As the advanced regional anesthesia education program continues to improve, we hope to demonstrate levels of validity, reliability, and usability by other programs.

    Full Text Available Current efforts to study the biological effects of global change have focused on ecological responses, particularly shifts in species ranges. Mostly ignored are microevolutionary changes. Genetic changes may be at least as important as ecological ones in determining species' responses. In addition, such changes may be a sensitive indicator of global changes that will provide different information than that provided by range shifts. We discuss potential candidate systems to use in such monitoring programs. Studies of Drosophila subobscura suggest that its chromosomal inversion polymorphisms are responding to global warming. Drosophila inversion polymorphisms can be useful indicators of the effects of climate change on populations and ecosystems. Other species also hold the potential to become important indicators of global change. Such studies might significantly influence ecosystem conservation policies and research priorities.

Objective To compare the effects of BiPAP ventilation combined with lung recruitment maneuvers(LRM) with low tidal volume A/C ventilation in patients with acute respiratory distress syndrome (ARDS). Methods A prospective, randomized comparison of BiPAP mechanical ventilation combined with lung recruitment maneuvers(test group) with low tidal volume A/C ventilation (control group) was conducted in 28 patients with ARDS. FiO2/PaO2 ratio, respiratory system compliance(Cs), central venous pressure (CVP), duration of ventilation support were recorded at 0 h, 48 h and 72 h separately. The ventilation associated lung injury and mortality at 28 d were also recorded. Results The FiO2/PaO2 ratio were (298±16) and (309±16) cm H2O, Cs were (38.4±2.2) and (42.0±1.3) ml/cm H2O, CVP were (13.8±0.8) and (11.6±0.7) cm H2O in the test group at 48 h and 72 h separately. In the control group, FiO2/PaO2 ratio were (212±12) and (246±17) cm H2O, Cs were (29.5±1.3) and (29.0±1.0) ml/cm H2O, CVP were 18.6±1.1 and (16.8±1.0) cm H2O. The results were better in the test group as compared with the control group (t=10.03-29. 68, all P<0.01). The duration of ventilation support in the test group was shorter than the control group [(14±3) d vs (19±3)d, t=4.80, P<0.01]. The mortality in 28 d and ventilation associated lung injury were similar in the two groups. Conclusion The results show that combination of LRM with BiPAP mode ventilation, as compared with the control group, contributes to the improved FiO2/PaO2 ratio, pulmonary compliance, stable homodynamic and shorter duration of ventilation support in patients with ARDs.

    Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq, conducted in the State of Paraná by the National Industrial Apprenticeship Service (Serviço Nacional de Aprendizagem Industrial - SENAI of Paraná. The sample by accessibility consists of the respondents of the questionnaire, and descriptive statistics was applied to the collected data. The survey results show the characteristics of the companies' performance evaluation, controllers' remuneration composition, and the system of variable remuneration of the controllers. It is concluded that the method of performance evaluation mostly practiced by the sample companies that adopt variable compensation system is the participation in the profits, and that the motivation for its implementation from the point of view of the controllers is indifferent. This result instigates research to investigate to what extent the performance evaluation system can contribute to minimize the agency conflict from the perspective of freedom of the controllers in terms of hierarchical subordination.

    Urbin, J.; /Fermilab


    The DO cryogenic system is controlled by a TI565-PLC based control system. This allows the system to be unmanned when in steady state operation. System experts will need to be contacted when system parameters exceed normal operating points and reach alarm setpoints. The labwide FIRUS system provides one alarm monitor and communication link. An autodialer provides a second and more flexible alarm monitor and communication link. The autodialer monitors contact points in the control system and after receiving indication of an alarm accesses a list of experts which it calls until it receives an acknowledgement. There are several manufacturers and distributors of autodialer systems. This EN explains the search process the DO cryo group used to fmd an autodialer system that fit the cryo system's needs and includes information and specs for the unit we chose.

  11. Linking Political Systems and War Systems

    DEFF Research Database (Denmark)

    Harste, Gorm


    Decisive parts of the Western political system have demonstrated a seemingly surprising misinterpretation of military might. As Madelaine Albright has suggested, the mighty perceived themselves as "almighty". Political power seems to have invested in instrumental coercive power relations and found...... military coercion to be the appropriate mean. Using the system theory and the theory of systemic risks displayed by the German sociologist Niklas Luhmann the article demonstrates how military systems due to their own autonomy and autopoiesis do not fit into the idea of political government....... The Clausewitzian ideal of a political system that could continue its power games by means of war was moderated by Clausewitz' own analysis of "friction". How can a political system be so blind towards the possibilities of another system? What are the risks of systemic blind spots? The argument of the paper...

    Abin, Jorge; Nemeth, Horacio; Friedmann, Ignacio


    From a national level to give Internet technology support, the Nationwide Integrated Healthcare System in Uruguay requires a model of Information Systems Architecture. This system has multiple healthcare providers (public and private), and a strong component of supplementary services. Thus, the data processing system should have an architecture that considers this fact, while integrating the central services provided by the Ministry of Public Health. The national electronic health record, as well as other related data processing systems, should be based on this architecture. The architecture model described here conceptualizes a federated framework of electronic health record systems, according to the IHE affinity model, HL7 standards, local standards on interoperability and security, as well as technical advice provided by AGESIC. It is the outcome of the research done by AGESIC and Systems Integration Laboratory (LINS) on the development and use of the e-Government Platform since 2008, as well as the research done by the team since 2013.

  15. for hybrid dynamical systems

    Directory of Open Access Journals (Sweden)

    Wassim M. Haddad


    Full Text Available In this paper we develop a unified dynamical systems framework for a general class of systems possessing left-continuous flows; that is, left-continuous dynamical systems. These systems are shown to generalize virtually all existing notions of dynamical systems and include hybrid, impulsive, and switching dynamical systems as special cases. Furthermore, we generalize dissipativity, passivity, and nonexpansivity theory to left-continuous dynamical systems. Specifically, the classical concepts of system storage functions and supply rates are extended to left-continuous dynamical systems providing a generalized hybrid system energy interpretation in terms of stored energy, dissipated energy over the continuous-time dynamics, and dissipated energy over the resetting events. Finally, the generalized dissipativity notions are used to develop general stability criteria for feedback interconnections of left-continuous dynamical systems. These results generalize the positivity and small gain theorems to the case of left-continuous, hybrid, and impulsive dynamical systems.

  10. Integrated Systems Health Management for Intelligent Systems (United States)

    Figueroa, Fernando; Melcher, Kevin


    The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

  11. Epilogue: Systems Approaches and Systems Practice (United States)

    Reynolds, Martin; Holwell, Sue

    Each of the five systems approaches discussed in this volume: system dynamics (SD), the viable systems model (VSM), strategic options development and analysis (SODA), soft systems methodology (SSM) and critical systems heuristics (CSH) has a pedigree. Not in the sense of the sometimes absurd spectacle of animals paraded at dog shows. Rather, their pedigree derives from their systems foundations, their capacity to evolve and their flexibility in use. None of the five approaches has developed out of use in restricted and controlled contexts of either low or high levels of complicatedness. Neither has any one of them evolved as a consequence of being applied only to situations with either presumed stakeholder agreement on purpose, or courteous disagreement amongst stakeholders, or stakeholder coercion. The compilation is not a celebration of abstract ‘methodologies', but of theoretically robust approaches that have a genuine pedigree in practice.

    With the increasing number of detected exoplanet samples,the statistical properties of planetary systems have become much clearer.In this review,we summarize the major statistical results that have been revealed mainly by radial velocity and transiting observations,and try to interpret them within the scope of the classical core-accretion scenario of planet formation,especially in the formation of different orbital architectures for planetary systems around main sequence stars.Based on the different possible formation routes for different planet systems,we tentatively classify them into three major catalogs:hot Jupiter systems,standard systems and distant giant planet systems.The standard systems can be further categorized into three sub-types under different circumstances:solar-like systems,hot Super-Earth systems,and subgiant planet systems.We also review the theory of planet detection and formation in binary systems as well as planets in star clusters.

  15. Hot Spot Removal System: System description

    Energy Technology Data Exchange (ETDEWEB)



    Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site. The Hot Spot Removal System consists of a suite of technologies that will be utilized to locate and remove source terms. Components of the system can also be used in a variety of other cleanup activities. This Hot Spot Removal System Description document presents technologies that were considered for possible inclusion in the Hot Spot Removal System, technologies made available to the Hot Spot Removal System, industrial interest in the Hot Spot Removal System`s subsystems, the schedule required for the Hot Spot Removal System, the evaluation of the relevant technologies, and the recommendations for equipment and technologies as stated in the Plan section.

    For decades, biomedical and pharmaceutical researchers have worked to devise new and more effective therapeutics to treat diseases affecting the central nervous system. The blood-brain barrier effectively protects the brain, but poses a profound challenge to drug delivery across this barrier. Many traditional drugs cannot cross the blood-brain barrier in appreciable concentrations, with less than 1% of most drugs reaching the central nervous system, leading to a lack of available treatments for many central nervous system diseases, such as stroke, neurodegenerative disorders, and brain tumors. Due to the ineffective nature of most treatments for central nervous system disorders, the development of novel drug delivery systems is an area of great interest and active research. Multiple novel strategies show promise for effective central nervous system drug delivery, giving potential for more effective and safer therapies in the future. This review outlines several novel drug delivery techniques, including intranasal drug delivery, nanoparticles, drug modifications, convection-enhanced infusion, and ultrasound-mediated drug delivery. It also assesses possible clinical applications, limitations, and examples of current clinical and preclinical research for each of these drug delivery approaches. Improved central nervous system drug delivery is extremely important and will allow for improved treatment of central nervous system diseases, causing improved therapies for those who are affected by central nervous system diseases.

    Social Tagging Systems are web applications in which users upload resources (e.g., bookmarks, videos, photos, etc.) and annotate it with a list of freely chosen keywords called tags. This is a grassroots approach to organize a site and help users to find the resources they are interested in. Social tagging systems are open and inherently social; features that have been proven to encourage participation. However, with the large popularity of these systems and the increasing amount of user-contributed content, information overload rapidly becomes an issue. Recommender Systems are well known appl

    Grygiel, M.L. [Westinghouse Hanford Co., Richland, WA (United States)


    The Site Systems Engineering Management Plan (SEMP) is the Westinghouse Hanford Company (WHC) implementation document for the Hanford Site Systems Engineering Policy, (RLPD 430.1) and Systems Engineering Criteria Document and Implementing Directive, (RLID 430.1). These documents define the US Department of Energy (DOE), Richland Operations Office (RL) processes and products to be used at Hanford to implement the systems engineering process at the site level. This SEMP describes the products being provided by the site systems engineering activity in fiscal year (FY) 1996 and the associated schedule. It also includes the procedural approach being taken by the site level systems engineering activity in the development of these products and the intended uses for the products in the integrated planning process in response to the DOE policy and implementing directives. The scope of the systems engineering process is to define a set of activities and products to be used at the site level during FY 1996 or until the successful Project Hanford Management Contractor (PHMC) is onsite as a result of contract award from Request For Proposal DE-RP06-96RL13200. Following installation of the new contractor, a long-term set of systems engineering procedures and products will be defined for management of the Hanford Project. The extent to which each project applies the systems engineering process and the specific tools used are determined by the project`s management.

  13. On generalized Volterra systems (United States)

    Charalambides, S. A.; Damianou, P. A.; Evripidou, C. A.


    We construct a large family of evidently integrable Hamiltonian systems which are generalizations of the KM system. The algorithm uses the root system of a complex simple Lie algebra. The Hamiltonian vector field is homogeneous cubic but in a number of cases a simple change of variables transforms such a system to a quadratic Lotka-Volterra system. We present in detail all such systems in the cases of A3, A4 and we also give some examples from higher dimensions. We classify all possible Lotka-Volterra systems that arise via this algorithm in the An case.

    Ungerer, M J; le Roux, F P


    A true universal co-axial anaesthetic system has been designed. This system may be used either as a Mapleson A circuit during spontaneous ventilation or as a Mapleson D circuit during controlled ventilation. Conversion to either system may be conveniently carried out by interchanging the pop-off valve and fresh gas inlet, without disconnecting the system from the patient. Resistance to flow of both tubes has been measured and was found to be within acceptable limits. The efficiency of this system in a Mapleson A arrangement was compared with that of a conventional Magill circuit during spontaneous breathing in 2 conscious volunteers. It was shown that no significant difference exists between these systems eith regard to rebreathing, and that the universal co-axial system may be used as efficiently and economically as the Magill circuit during spontaneous ventilation. The co-axial system can be easily connected to a circle system, combining the advantages of the two systems.

  17. The Solar System as an Exoplanetary System

    CERN Document Server

    Martin, Rebecca G


    With the availability of considerably more data, we revisit the question of how special our Solar System is, compared to observed exoplanetary systems. To this goal, we employ a mathematical transformation that allows for a meaningful, statistical comparison. We find that the masses and densities of the giant planets in our Solar System are very typical, as is the age of the Solar System. While the orbital location of Jupiter is somewhat of an outlier, this is most likely due to strong selection effects towards short-period planets. The eccentricities of the planets in our Solar System are relatively small compared to those in observed exosolar systems, but still consistent with the expectations for an 8-planet system (and could, in addition, reflect a selection bias towards high-eccentricity planets). The two characteristics of the Solar System that we find to be most special are the lack of super-Earths with orbital periods of days to months and the general lack of planets inside of the orbital radius of Me...

  3. Systems Theory and Systems Approach to Leadership

    Directory of Open Access Journals (Sweden)

    Dr.Sc. Berim Ramosaj


    Full Text Available Systems theory is product of the efforts of many researchers to create an intermediate field of coexistence of all sciences. If not for anything else, because of the magnitude that the use of systemic thinking and systemic approach has taken, it has become undisputed among the theories. Systems theory not only provides a glossary of terms with which researchers from different fields can be understood, but provides a framework for the presentation and interpretation of phenomena and realities. This paper addresses a systematic approach to leadership, as an attempt to dredge leadership and systems theory literature to find the meeting point. Systems approach is not an approach to leadership in terms of a manner of leader’s work, but it’s the leader's determination to factorize in his leadership the external environment and relationships with and among elements. Leader without followers is unable to exercise his leadership and to ensure their conviction he should provide a system, a structure, a purpose, despite the alternative chaos. Systems approach clarifies the thought on the complexity and dynamism of the environment and provides a framework for building ideas. If the general system theory is the skeleton of science (Boulding: 1956, this article aims to replenish it with leadership muscles by prominent authors who have written on systems theory and leadership, as well as through original ideas. In this work analytical methods were used (by analyzing approaches individually as well as synthetic methods (by assaying individual approaches in context of entirety. The work is a critical review of literature as well as a deductive analysis mingled with models proposed by authors through inductive analysis. Meta-analysis has been used to dissect the interaction and interdependence between leadership approaches.

  4. A distribution management system

    The development of new distribution automation applications is considerably wide nowadays. One of the most interesting areas is the development of a distribution management system (DMS) as an expansion of the traditional SCADA system. At the power transmission level such a system is called an energy management system (EMS). The idea of these expansions is to provide supporting tools for control center operators in system analysis and operation planning. The needed data for new applications is mainly available in some existing systems. Thus the computer systems of utilities must be integrated. The main data source for the new applications in the control center are the AM/FM/GIS (i.e. the network database system), the SCADA, and the customer information system (CIS). The new functions can be embedded in some existing computer system. This means a strong dependency on the vendor of the existing system. An alternative strategy is to develop an independent system which is integrated with other computer systems using well-defined interfaces. The latter approach makes it possible to use the new applications in various computer environments, having only a weak dependency on the vendors of the other systems. In the research project this alternative is preferred and used in developing an independent distribution management system

  5. A System of Systems Approach to the EU Energy System (United States)

    Jess, Tom; Madani, Kaveh; Mahlooji, Maral; Ristic, Bora


    Around the world, measures to prevent dangerous climate change are being adopted and may change energy systems fundamentally. The European Union (EU) is committed to reducing greenhouse gas emission by 20% by 2020 and by 80-95% by 2050. In order to achieve this, EU member states aim to increase the share of renewables in the energy mix to 20% by 2020. This commitment comes as part of a series of other aims, principles, and policies to reform the EU's energy system. Cost-efficiency in the emissions reductions measures as well as strategic goals under the Resource Efficient Europe flagship initiative which would include a more prudent approach to other natural resources such as water and land. Using the "System of Systems Approach", as from Hadian and Madani (2015), energy sources' Relative Aggregate Footprints (RAF) in the EU are evaluated. RAF aggregates across four criteria: carbon footprint, water footprint, land footprint, and economic cost. The four criteria are weighted by resource availability across the EU and for each Member State. This provides an evaluation of the overall resource use efficiency of the EU's energy portfolio and gives insight into the differences in the desirability of energy sources across Member States. Broadly, nuclear, onshore wind, and geothermal are most desirable under equal criteria weights and EU average weighting introduces only small changes in the relative performance of only few technologies. The member state specific weightings show that most countries have similar energy technology preferences. However, the UK deviates most strongly from the average, with an even stronger preference for nuclear and coal. Sweden, Malta and Finland also deviate from the typical preferences indicating the complexity in play in reforming the EU energy system.

  6. Intelligent systems technology infrastructure for integrated systems (United States)

    Lum, Henry


    A system infrastructure must be properly designed and integrated from the conceptual development phase to accommodate evolutionary intelligent technologies. Several technology development activities were identified that may have application to rendezvous and capture systems. Optical correlators in conjunction with fuzzy logic control might be used for the identification, tracking, and capture of either cooperative or non-cooperative targets without the intensive computational requirements associated with vision processing. A hybrid digital/analog system was developed and tested with a robotic arm. An aircraft refueling application demonstration is planned within two years. Initially this demonstration will be ground based with a follow-on air based demonstration. System dependability measurement and modeling techniques are being developed for fault management applications. This involves usage of incremental solution/evaluation techniques and modularized systems to facilitate reuse and to take advantage of natural partitions in system models. Though not yet commercially available and currently subject to accuracy limitations, technology is being developed to perform optical matrix operations to enhance computational speed. Optical terrain recognition using camera image sequencing processed with optical correlators is being developed to determine position and velocity in support of lander guidance. The system is planned for testing in conjunction with Dryden Flight Research Facility. Advanced architecture technology is defining open architecture design constraints, test bed concepts (processors, multiple hardware/software and multi-dimensional user support, knowledge/tool sharing infrastructure), and software engineering interface issues.

    Chassin, David P.; Malard, Joel M.; Posse, Christian; Gangopadhyaya, Asim; Lu, Ning; Katipamula, Srinivas; Mallow, J V.


    Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of today's most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This report explores the state-of-the-art physical analogs for understanding the behavior of some econophysical systems and deriving stable and robust control strategies for using them. We review and discuss applications of some analytic methods based on a thermodynamic metaphor, according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood. We apply these methods to the question of how power markets can be expected to behave under a variety of conditions.

    Akers, D.W.; Stoots, C.M.; Kraft, N.C.; Marts, D.J. [Idaho National Engineering Lab., Idaho Falls, ID (United States)


    The Rover Waste Assay System (RWAS) is a nondestructive assay system designed for the rapid assay of highly-enriched {sup 235}U contaminated piping, tank sections, and debris from the Rover nuclear rocket fuel processing facility at the Idaho Chemical Processing Plant. A scanning system translates a NaI(Tl) detector/collimator system over the structural components where both relative and calibrated measurements for {sup 137}Cs are made. Uranium-235 concentrations are in operation and is sufficiently automated that most functions are performed by the computer system. These functions include system calibration, problem identification, collimator control, data analysis, and reporting. Calibration of the system was done through a combination of measurements on calibration standards and benchmarked modeling. A description of the system is presented along with the methods and uncertainties associated with the calibration and analysis of the system for components from the Rover facility. 4 refs., 2 figs., 4 tabs.

  9. Enhanced nurse call systems. (United States)


    This Evaluation focuses on high-end computerized nurse call systems--what we call enhanced systems. These are highly flexible systems that incorporate microprocessor and communications technologies to expand the capabilities of the nurse call function. Enhanced systems, which vary in configuration from one installation to the next, typically consist of a basic system that provides standard nurse call functionality and a combination of additional enhancements that provide the added functionality the facility desires. In this study, we examine the features that distinguish enhanced nurse call systems from nonenhanced systems, focusing on their application and benefit to healthcare facilities. We evaluated seven systems to determine how well they help (1) improve patient care, as well as increase satisfaction with the care provided, and (2) improve caregiver efficiency, as well as increase satisfaction with the work environment. We found that all systems meet these objectives, but not all systems perform equally well for all implementations. Our ratings will help facilities identify those systems that offer the most effective features for their intended use. The study also includes a Technology Management Guide to help readers (1) determine whether they'll benefit from the capabilities offered by enhanced systems and (2) target a system for purchase and equip the system for optimum performance and cost-effective operation.

Major considerations of this analysis include: (1) Operational life of the SET; (2) Geometric constraints on the track layout; (3) Operating loads on the track; (4) Environmentally induced loads on the track; (5) Power supply (electrification) requirements; and (6) Instrumentation and control requirements. This analysis will provide the basis for development of the system description document (SDD) for the SET. This analysis also defines the interfaces that need to be considered in the design of the SET. These interfaces include, but are not limited to, the following: (1) Waste handling building; (2) Monitored Geologic Repository (MGR) surface site layout; (3) Waste Emplacement System (WES); (4) Waste Retrieval System (WRS); (5) Ground Control System (GCS); (6) Ex-Container System (XCS); (7) Subsurface Electrical Distribution System (SED); (8) MGR Operations Monitoring and Control System (OMC); (9) Subsurface Facility System (SFS); (10) Subsurface Fire Protection System (SFR); (11) Performance Confirmation Emplacement Drift Monitoring System (PCM); and (12) Backfill Emplacement System (BES).

  2. System Information Distribution in Massive MIMO Systems


    Sörman, Simon


    The 5th generation mobile telecommunication system (5G) is currently being specified and developed, with large expectations on throughput and efficiency. While 4G and more specifically LTE might constitute a basis of the design of the network, there are some parts that should be improved. One thing to improve is the static signalling that occurs very frequently in a 4G network, of which system information such as synchronization signals, detection of network frequencies, operators, configurat...

  5. Operating System for Runtime Reconfigurable Multiprocessor Systems

    Directory of Open Access Journals (Sweden)

    Diana Göhringer


    Full Text Available Operating systems traditionally handle the task scheduling of one or more application instances on processor-like hardware architectures. RAMPSoC, a novel runtime adaptive multiprocessor System-on-Chip, exploits the dynamic reconfiguration on FPGAs to generate, start and terminate hardware and software tasks. The hardware tasks have to be transferred to the reconfigurable hardware via a configuration access port. The software tasks can be loaded into the local memory of the respective IP core either via the configuration access port or via the on-chip communication infrastructure (e.g. a Network-on-Chip. Recent-series of Xilinx FPGAs, such as Virtex-5, provide two Internal Configuration Access Ports, which cannot be accessed simultaneously. To prevent conflicts, the access to these ports as well as the hardware resource management needs to be controlled, e.g. by a special-purpose operating system running on an embedded processor. For that purpose and to handle the relations between temporally and spatially scheduled operations, the novel approach of an operating system is of high importance. This special purpose operating system, called CAP-OS (Configuration Access Port-Operating System, which will be presented in this paper, supports the clients using the configuration port with the services of priority-based access scheduling, hardware task mapping and resource management.

  14. Generalized adjoint systems

    CERN Document Server

    Serakos, Demetrios


    This book defines and develops the generalized adjoint of an input-output system. It is the result of a theoretical development and examination of the generalized adjoint concept and the conditions under which systems analysis using adjoints is valid. Results developed in this book are useful aids for the analysis and modeling of physical systems, including the development of guidance and control algorithms and in developing simulations. The generalized adjoint system is defined and is patterned similarly to adjoints of bounded linear transformations. Next the elementary properties of the generalized adjoint system are derived. For a space of input-output systems, a generalized adjoint map from this space of systems to the space of generalized adjoints is defined. Then properties of the generalized adjoint map are derived. Afterward the author demonstrates that the inverse of an input-output system may be represented in terms of the generalized adjoint. The use of generalized adjoints to determine bounds for ...

  19. Saturated Switching Systems

    CERN Document Server

    Benzaouia, Abdellah


    Saturated Switching Systems treats the problem of actuator saturation, inherent in all dynamical systems by using two approaches: positive invariance in which the controller is designed to work within a region of non-saturating linear behaviour; and saturation technique which allows saturation but guarantees asymptotic stability. The results obtained are extended from the linear systems in which they were first developed to switching systems with uncertainties, 2D switching systems, switching systems with Markovian jumping and switching systems of the Takagi-Sugeno type. The text represents a thoroughly referenced distillation of results obtained in this field during the last decade. The selected tool for analysis and design of stabilizing controllers is based on multiple Lyapunov functions and linear matrix inequalities. All the results are illustrated with numerical examples and figures many of them being modelled using MATLAB®. Saturated Switching Systems will be of interest to academic researchers in con...

  9. Cross Disciplinary Biometric Systems

    CERN Document Server

    Liu, Chengjun


    Cross disciplinary biometric systems help boost the performance of the conventional systems. Not only is the recognition accuracy significantly improved, but also the robustness of the systems is greatly enhanced in the challenging environments, such as varying illumination conditions. By leveraging the cross disciplinary technologies, face recognition systems, fingerprint recognition systems, iris recognition systems, as well as image search systems all benefit in terms of recognition performance.  Take face recognition for an example, which is not only the most natural way human beings recognize the identity of each other, but also the least privacy-intrusive means because people show their face publicly every day. Face recognition systems display superb performance when they capitalize on the innovative ideas across color science, mathematics, and computer science (e.g., pattern recognition, machine learning, and image processing). The novel ideas lead to the development of new color models and effective ...

    Engineering quantum systems offers great opportunities both technologically and scientifically for communication, computation, and simulation. The construction and operation of large scale quantum information devices presents a grand challenge and a major issue is the effective control of coherent dynamics. This is often in the presence of decoherence which further complicates the task of determining the behaviour of the system. Here, we show how to determine open system Markovian dynamics of a quantum system with restricted initialisation and partial output state information.

  11. The complement system in systemic autoimmune disease. (United States)

    Chen, Min; Daha, Mohamed R; Kallenberg, Cees G M


    Complement is part of the innate immune system. Its major function is recognition and elimination of pathogens via direct killing and/or stimulation of phagocytosis. Activation of the complement system is, however, also involved in the pathogenesis of the systemic autoimmune diseases. Activation via the classical pathway has long been recognized in immune complex-mediated diseases such as cryoglobulinemic vasculitis and systemic lupus erythematosus (SLE). In SLE, the role of complement is somewhat paradoxical. It is involved in autoantibody-initiated tissue damage on the one hand, but, on the other hand, it appears to have protective features as hereditary deficiencies of classical pathway components are associated with an increased risk for SLE. There is increasing evidence that the alternative pathway of complement, even more than the classical pathway, is involved in many systemic autoimmune diseases. This is true for IgA-dominant Henoch Schönlein Purpura, in which additional activation of the lectin pathway contributes to more severe disease. In anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis the complement system was considered not to be involved since immunoglobulin deposition is generally absent in the lesions. However, recent studies, both in human and animal models, demonstrated complement activation via the alternative pathway as a major pathogenic mechanism. Insight into the role of the various pathways of complement in the systemic autoimmune diseases including the vasculitides opens up new ways of treatment by blocking effector pathways of complement. This has been demonstrated for monoclonal antibodies to C5 or C5a in experimental anti-phospholipid antibody syndrome and ANCA-associated vasculitis.

    Petascale High-Performance Computing (HPC) systems are among the largest systems in the world. Intrepid, one such system, is a 40,000 node, 556 teraflop Blue Gene/P system that has been deployed at Argonne National Laboratory. In this paper, we provide some background about the system and our administration experiences. In particular, due to the scale of the system, we have faced a variety of issues, some surprising to us, that are not common in the commodity world. We discuss our expectations, these issues, and approaches we have used to address them. HPC systems are a bellwether for computing systems at large, in multiple regards. HPC users are motivated by the need for absolute performance; this results in two important pushes. HPC users are frequently early adopters of new technologies and techniques. Successful technologies, like Infiniband, prove their value in HPC before gaining wider adoption. Unfortunately, this early adoption alone is not sufficient to achieve the levels of performance required by HPC users; parallelism must also be harnessed. Over the last 15 years, beowulf clustering has provided amazing accessibility to non-HPC-savvy and even non-technical audiences. During this time, substantial adoption of clustering has occurred in many market segments unrelated to computational science. A simple trend has emerged: the scale and performance of high-end HPC systems are uncommon at first, but become commonplace over the course of 3-5 years. For example, in early 2003, several systems on the Top500 list consisted of either 1024 nodes or 4096-8192 cores. In 2008, such systems are commonplace. The most recent generation of high-end HPC systems, so called petascale systems, are the culmination of years of research and development in research and academia. Three such systems have been deployed thus far. In addition to the 556 TF Intrepid system at Argonne National Laboratory, a 596 TF Blue Gene/L-based system has been deployed at Lawrence Livermore

    Gamble, Bruce B.; Sidi-Yekhlef, Ahmed; Schwall, Robert E.; Driscoll, David I.; Shoykhet, Boris A.


    A system for cooling a superconductor device includes a cryocooler located in a stationary reference frame and a closed circulation system external to the cryocooler. The closed circulation system interfaces the stationary reference frame with a rotating reference frame in which the superconductor device is located. A method of cooling a superconductor device includes locating a cryocooler in a stationary reference frame, and transferring heat from a superconductor device located in a rotating reference frame to the cryocooler through a closed circulation system external to the cryocooler. The closed circulation system interfaces the stationary reference frame with the rotating reference frame.

    The development of new distribution automation applications is considerably wide nowadays. One of the most interesting areas is the development of a distribution management system (DMS) as an expansion to the traditional SCADA system. At the power transmission level such a system is called an energy management system (EMS). The idea of these expansions is to provide supporting tools for control center operators in system analysis and operation planning. Nowadays the SCADA is the main computer system (and often the only) in the control center. However, the information displayed by the SCADA is often inadequate, and several tasks cannot be solved by a conventional SCADA system. A need for new computer applications in control center arises from the insufficiency of the SCADA and some other trends. The latter means that the overall importance of the distribution networks is increasing. The slowing down of load-growth has often made network reinforcements unprofitable. Thus the existing network must be operated more efficiently. At the same time larger distribution areas are for economical reasons being monitored at one control center and the size of the operation staff is decreasing. The quality of supply requirements are also becoming stricter. The needed data for new applications is mainly available in some existing systems. Thus the computer systems of utilities must be integrated. The main data source for the new applications in the control center are the AM/FM/GIS (i.e. the network database system), the SCADA, and the customer information system (CIS). The new functions can be embedded in some existing computer system. This means a strong dependency on the vendor of the existing system. An alternative strategy is to develop an independent system which is integrated with other computer systems using well-defined interfaces. The latter approach makes it possible to use the new applications in various computer environments, having only a weak dependency on the

  19. Liver in systemic disease

    Institute of Scientific and Technical Information of China (English)


    Potential causes of abnormal liver function tests include viral hepatitis, alcohol intake, nonalcoholic fatty liver disease, autoimmune liver diseases, hereditary diseases, hepatobiliary malignancies or infection, gallstones and drug-induced liver injury. Moreover, the liver may be involved in systemic diseases that mainly affect other organs. Therefore, in patients without etiology of liver injury by screening serology and diagnostic imaging, but who have systemic diseases, the abnormal liver function test results might be caused by the systemic disease. In most of these patients, the systemic disease should be treated primarily. However, some patients with systemic disease and severe liver injury or fulminant hepatic failure require intensive treatments of the liver.
