2017-01-01

A Brane Craft is a membrane spacecraft with solar cells, command and control electronics, communications systems, antennas, propulsion systems, attitude and proximity sensors, and shape control actuators as thin film structures manufactured on 10 micron thick plastic sheets. This revolutionary spacecraft design can have a thickness of tens of microns with a surface area of square meters to maximize area-to-mass ratios for exceptionally low-mass spacecraft. Communications satellites, solar power satellites, solar electric propulsion stages, and solar sails can benefit from Brane Craft design. It also enables new missions that require low-mass spacecraft with exceptionally high delta-V. Active removal of orbital debris from Earth orbit is the target application for this study.

Leading to Crafting: The Relation Between Leadership Perception and Nurses' Job Crafting.

Science.gov (United States)

Esteves, Tiago; Pereira Lopes, Miguel

2017-06-01

Whenever individuals adapt their jobs to make them closer of their personal preferences, they are performing job crafting. This study aims to investigate if the way nurses perceive their leaders' behaviors is related with job crafting development. To do so, a quantitative analysis was conducted among a group of 325 Portuguese nurses. Results indicate that the perception of an empowering leader was found to be strongly related with the increase of challenges in the work environment, and with the development of stronger relations with direct managers and co-workers, which are two job crafting dimensions. The perception of a directive leader was found to be positively related with the avoidance of performing hindering tasks. Strengthening relations with direct managers and co-workers was found to be particularly related to leadership perception. Theoretical and practical implications are discussed.

The meanings of craft to an occupational therapist.

Science.gov (United States)

Harris, Emma

2008-06-01

Craft was the first therapeutic occupation of occupational therapy. Since the early days of the profession, the value of craft in practice is a topic that has been discussed with fluctuating interest. Recent discussions by occupational therapists have reinforced that although craft is relevant to occupational therapy, there are uncertainties about its place in contemporary practice. Presently, scholars have identified that occupation is both the center of human experience and the core of our profession. Therefore, this study aimed to begin to clarify the meaning of craft to practice today by gaining a deep understanding of the meanings that one occupational therapist attributes to craft. Using narrative inquiry, data were gathered through a conversation held between the research participant and myself. A reflexive journal was also kept to support this data gathering process. Narrative analysis enabled intimate engagement with the data and the emergence of themes and sub-themes. The findings, in the form of an interpretive story, suggest first, that craft-making has therapeutic value; second, that reasoning about the therapeutic use of craft is similar to reasoning about other therapeutic activities; and third, that personal experience with craft-making can influence the selection of craft as therapeutic media. From this study, further research into the impact personal and professional experiences can have on choice of therapeutic media and an analysis of the sociopolitical context of the meanings that occupational therapists attribute to craft-making is suggested.

The craft of intensive care medicine.

Science.gov (United States)

Carmel, Simon

2013-06-01

The practice of medicine is often represented as a dualism: is medicine a 'science' or an 'art'? This dualism has been long-lasting, with evident appeal for the medical profession. It also appears to have been rhetorically powerful, for example in enabling clinicians to resist the encroachment of 'scientific' evidence-based medicine into core areas of medical work such as individual clinical judgement. In this article I want to make the case for a more valid conceptualisation of medical practice: that it is a 'craft' activity. The case I make is founded on a theoretical synthesis of the concept of craft, combined with an analysis of ethnographic observations of routine medical practice in intensive care. For this context the craft aspects of medical work can be seen in how biomedical and other types of knowledge are used in practice, the embodied skills and practical judgement of practitioners and the technological and material environment. These aspects are brought together in two conceptual dimensions for 'craft': first, the application of knowledge; second, interaction with the material world. Some practical and political implications of a 'craft' metaphor for medical practice are noted. © 2013 The Author.

2018-01-01

The main objective is to study the effects of job crafting activities of elder care and nursing home employees on their perceived well-being and quality of care in two European countries, Spain and Sweden. The Job Crafting, the General Health, and the Quality of Care questionnaires were administered to 530 employees. Correlations and hierarchical regression analyses were performed. Results confirm the effects of job crafting on quality of care ( r = .291, p employees' well-being ( r = .201, p well-being in Spain and Sweden and with quality of care in Spain. On the contrary, in Sweden, the relationship between job crafting and well-being was not linear. Job crafting contributes significantly to employees' and residents' well-being. Management should promote job crafting to co-create meaningful and productive work. Cultural effects are proposed to explain the differences found.

Diverse orientations in craft education: Student teachers’ conceptions and perceptions

Directory of Open Access Journals (Sweden)

Tarja Kröger

2016-03-01

Full Text Available Craft education in Finland has been in a state of change. The concept of a holistic craft process was implemented in the National Core Curriculum in 2004 and the new Curriculum from 2014 strengthened it. Craft and holistic craft is not one unity but includes several orientations. This study aims to research student teachers’ conceptions and perceptions about diverse orientations and the necessity of craft education before they begin their studies in craft pedagogy. Given that the beliefs that student teachers bring to professional learning play a pivotal role in influencing what they can learn from teacher education, they are a subject worthy of investigation. The data consists of on‐line questionnaire answers by student teachers (N=113 at the University of Finland in teacher education in 2014. The on-line questionnaire was answered at the beginning of a basic course in textile craft education at an early stage of their teacher studies. Findings suggest that student teachers conceive of craft education primarily as model-oriented and skill-oriented rather than design-oriented and expression-oriented. Student teachers think that craft education is needed at school, but explanations are not very diverse. The findings of this study can be useful in the process of developing teacher education programmes.

Self-crafting vegetable snacks: testing the IKEA-effect in children.

Science.gov (United States)

Raghoebar, Sanne; van Kleef, Ellen; de Vet, Emely

2017-01-01

The purpose of this paper is to test whether the IKEA-effect (Norton et al. , 2012) - better liking for self-crafted products than for identical products crafted by others - can be exploited to increase liking and consumption of vegetable snacks in children. A between-subjects experiment was conducted at an after school care facility. In total, 86 children aged four to six either crafted a peacock with vegetables or with non-food objects following an example. After the task, children ate snack vegetables ad libitum, and rated their liking for the vegetables and pride in crafting the peacock. No significant main effect of the vegetable snack creation on consumption and liking was observed. Also, perceived pride did not mediate the effect of self-crafting vegetable snacks on consumption of and liking for vegetables. Vegetable consumption did not differ between children who were either simply exposed to vegetable snacks while crafting or those who were crafting the vegetable snacks themselves. The equal consumption might suggest that this is caused by simple exposure, but more research is needed comparing self-crafting and exposure to a condition where there is no initial exposure to vegetables. Although the IKEA-effect has been demonstrated in adults, this is one of the first studies evaluating the IKEA-effect in children and as a means to increase liking for a generally disliked product in this target group, i.e. vegetables. The IKEA-effect could not be replicated under these more stringent conditions, where the experimental set-up enabled disentangling exposure and crafting effects.

Friedel-Crafts Acylation with Amides

Science.gov (United States)

Raja, Erum K.; DeSchepper, Daniel J.; Nilsson Lill, Sten O.; Klumpp, Douglas A.

2012-01-01

Friedel-Crafts acylation has been known since the 1870s and it is an important organic synthetic reaction leading to aromatic ketone products. Friedel-Crafts acylation is usually done with carboxylic acid chlorides or anhydrides while amides are generally not useful substrates in these reactions. Despite being the least reactive carboxylic acid derivative, we have found a series of amides capable of providing aromatic ketones in good yields (55–96%, 17 examples). We propose a mechanism involving diminished C-N resonance through superelectrophilic activation and subsequent cleavage to acyl cations. PMID:22690740

Constructing knowledge through perceptual processes in making craft-art

Directory of Open Access Journals (Sweden)

Full Text Available The focus of the study is on the knowledge that is constructed through perceptual processes during craft making in the context of the Finnish Basic Education in the Arts (BEA system. Craft studies in the BEA are defined as craft-art. The research method used is the grounded theory. The data consists of seven interviews and participant observations. Participants in the study are adolescents who study craft-art in the BEA system in Visual Art School, Aimo in Hämeenlinna. The aim of the article is to present, define and reflect on the concepts, properties and dimensions concerning perceptual processes that are discovered in this stage of the study following grounded theory procedures. The perceptual processes are an essential means of constructing knowledge in craft-art. Consequently, one aim of the study is to discuss how these processes are connected to various types of knowledge. The perceptual processes are described by seven concepts: imitative, anticipative, evaluative, experimental, emotional, temporal and bodily perceptions. They indicate on a conceptual level the characteristic of knowledge constructed through perceptual processes in craft-art. Further, theconcepts have several properties that can vary dimensionally between two qualities. The properties are activity, function and position. The dimensions of the properties vary from active to passive, formal to informal and internal to external. In conclusion, the concepts can describe a large range of incidents in different situations. They also seem to describe well the practice of  craft-art and there are several connections with pre-existing concepts of knowledge.Keywords: Craft, Knowledge, Perceptual process, Basic Education in the Arts, Grounded Theory

Job crafting: Towards a new model of individual job redesign

Directory of Open Access Journals (Sweden)

Maria Tims

2010-12-01

Research purpose: The purpose of the study was to fit job crafting in job design theory. Motivation for the study: The study was an attempt to shed more light on the types of proactive behaviours of individual employees at work. Moreover, we explored the concept of job crafting and its antecedents and consequences. Research design, approach and method: A literature study was conducted in which the focus was first on proactive behaviour of the employee and then on job crafting. Main findings: Job crafting can be seen as a specific form of proactive behaviour in which the employee initiates changes in the level of job demands and job resources. Job crafting may be facilitated by job and individual characteristics and may enable employees to fit their jobs to their personal knowledge, skills and abilities on the one hand and to their preferences and needs on the other hand. Practical/managerial implications: Job crafting may be a good way for employees to improve their work motivation and other positive work outcomes. Employees could be encouraged to exert more influence on their job characteristics. Contribution/value-add: This article describes a relatively new perspective on active job redesign by the individual, called job crafting, which has important implications for job design theories.

Craft vs. industrial: Habits, attitudes and motivations towards beer consumption in Mexico.

Science.gov (United States)

Gómez-Corona, Carlos; Escalona-Buendía, Héctor B; García, Mauricio; Chollet, Sylvie; Valentin, Dominique

2016-01-01

Food choices tend to be stable over time; they do not change fast, since consumers tend to act like creatures of habits. However, food habits can evolve, like currently the craft beer category. A change of habits involves a change of perception towards a product. Therefore, what is changing in the perception of beer? Two studies were conducted to address this question. First study was preliminary and aimed at exploring beer consumption habits in Mexico and a better understanding of craft beer representation among beer users. A questionnaire was administrated to 207 consumers in Mexico City during a beer festival. Results showed that respondents could be classified in: industrial beer (41.1%), occasional industrial (24.1%), and craft beer (34.8%) consumers. Craft cluster included mostly 25-35 years old men with high-income level. Among the craft beers cited by respondents from this cluster some are industrial, suggesting that the concept of craft beer might not be well defined, or defined in ideological terms. The second and main study was conducted using consumer ethnographies to understand the motivations and benefits of craft beer consumption. Opposite to industrial, craft beer emerges as an experience-based and symbolic product rather than a utilitarian one. The main motivation for drinking craft beer seems to be the quest of authenticity. Respondents' motivations to drink craft beer are generated by three important factors: desire for more knowledge, new taste experiences, and move away from the mainstream beer consumption. Craft consumers do not drink the product for its functional attributes, they consume it for what it means and as a consequence they build an identity, perceived as more authentic and unique, in comparison to the mainstream industrial beer consumption in Mexico.

Empowering leadership and job crafting: The role of employee optimism.

Science.gov (United States)

Thun, Sylvi; Bakker, Arnold B

2018-06-08

The objective of this study was to test the relationship between empowering leadership and job crafting and to examine the moderating role of optimism as a personal resource. We hypothesized that the association between empowering leadership and job crafting would be stronger for employees with high (vs. low) levels of optimism. A total of 331 Norwegian workers from a variety of occupations participated in our study. Results of structural equation modelling analysis generally supported our hypotheses. Empowering leadership was positively related to 3 of the 4 job crafting strategies investigated (increasing structural job resources, increasing social job resources, and increasing challenging job demands; but not reducing hindrance job demands). Moreover, as hypothesized, optimism strengthened the empowering leadership-job crafting relationship for increasing structural resources and increasing challenging demands. The results suggest that empowering leadership is an important antecedent of job crafting strategies, except for reducing hindrance demands. The implications of these findings are discussed.

Legal and economic implications of the German Craft Code Amendment 2004

Directory of Open Access Journals (Sweden)

Wolfgang Benzel

2012-01-01

Full Text Available As the main reason for initiating an amendment of the Trade and Crafts Code in 2004 was the decrease in the number of companies in general and the number of skilled crafts enterprises in particular and was also due to the fact that the number of employees in the skilled crafts sector had constantly fallen and many companies were not able to find a successor, it was the declared aim of the amendment to counter this structural crisis as well as reducing illegal employment and removing native discrimination. This would then ensure a higher level of employment especially through new company formations and takeovers of existing companies.In addition to providing an important contribution towards the assessment of the basic success of the 2004 Trade and Crafts Code amendment, the results can therefore be used at an international level for discussions on skilled crafts legislation outside Germany. As German skilled crafts legislation developed in a completely different manner from skilled crafts legislation in most other European countries, this aspect is particularly significant and it is conceivable that the results will be useful beyond the borders of the Federal Republic of Germany. The research findings will also be important in determining the limits of deregulation and when it can be considered counterproductive from an economic point of view.

Job crafting among health care professionals: The role of work engagement.

Science.gov (United States)

Bakker, Arnold B

2018-04-01

The aim of this study was to examine the impact of job crafting on the quality of the work environment of health care professionals. Job crafting refers to proactive behavior aimed at optimizing the fit between person and job. Using job demands-resources theory, we hypothesized that job crafting would be positively related to job resources and person-organisation fit, and negatively to hindrance demands. Furthermore, we hypothesized that these relationships would be qualified by work engagement. A total of 5,272 health care professionals from one of 35 different organisations filled out an electronic questionnaire (response is 55%). Regression analyses were used to test hypotheses. Consistent with hypotheses, job crafting in the form of increasing job resources was positively related to opportunities for development, performance feedback and P-O fit; and negatively related to hindrance job demands - particularly when work engagement was high. The combination of job crafting and work engagement is important for the realization of a resourceful work environment and fit between person and organisation. Interventions aimed at fostering job crafting should be tailored to the motivation of health care professionals. © 2017 John Wiley & Sons Ltd.

Full Text Available Contour Crafting is a novel technology in construction industry based on 3D printing that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. It is actually an approach to scale up automatic fabrication from building small industrial parts to constructing buildings. However, there are little information about contour crafting (CC in current use; present paper aims to describe the operational steps of creating a whole building by the machine reviewing relevant literature. Furthermore, it will represent the advantages of CC usage compared to traditional construction methods, as well as its applicability in construction industry.

A discussion of the necessity of craft education in the 21st century

Directory of Open Access Journals (Sweden)

Eva Veeber

2015-02-01

Full Text Available Craft education has held a permanent place in Estonian and Finnish schools, although its value and appreciation have changed over time. The aim of the article is to discuss the necessity of craft education in today’s world and its possible impact on the development of children and adolescents. The discussion seeks an interdisciplinary explanation using three perspectives that complement each other. The first describes the challenges of modern society with respect to individual development and schooling. The second deals with Aaron Antonovsky's theory of generalized resistance resources and an individual's possibility to manage in a stressful society. The third addresses the individual as a developing neurological being, along with the effect of learning and practicing motor skills on the human brain. We conclude that crafts is a multidisciplinary phenomenon, and that learning and practicing crafts promotes the comprehension of diversity and challenges in life. Additionally, educational crafts enriches the learning environment, offering opportunities to develop transferable skills that human beings constantly need in society. In addition, crafts provides a balanced way to come to understand the world and one’s role in it, by simultaneously promoting motor and cognitive development and making unique demands on one’s being.Keywords: crafts, craft education, making, sense of coherence, education, embodiment

The impact of job crafting on job demands, job resources, and well-being.

Science.gov (United States)

Tims, Maria; Bakker, Arnold B; Derks, Daantje

2013-04-01

This longitudinal study examined whether employees can impact their own well-being by crafting their job demands and resources. Based on the job demands-resources model, we hypothesized that employee job crafting would have an impact on work engagement, job satisfaction, and burnout through changes in job demands and job resources. Data was collected in a chemical plant at three time points with one month in between the measurement waves (N = 288). The results of structural equation modeling showed that employees who crafted their job resources in the first month of the study showed an increase in their structural and social resources over the course of the study (2 months). This increase in job resources was positively related to employee well-being (increased engagement and job satisfaction, and decreased burnout). Crafting job demands did not result in a change in job demands, but results revealed direct effects of crafting challenging demands on increases in well-being. We conclude that employee job crafting has a positive impact on well-being and that employees therefore should be offered opportunities to craft their own jobs.

Taking control: Is job crafting related to the intention to leave surgical training?

Science.gov (United States)

Dominguez, Luis Carlos; Stassen, Laurents; de Grave, Willem; Sanabria, Alvaro; Alfonso, Edgar; Dolmans, Diana

2018-01-01

The intention to leave surgical training, hereinafter referred as proxy of "attrition," is associated with poor well-being in the workplace. Attrition is suggested to diminish when residents possess job-crafting skills, that is, the ability to redefine their job in meaningful ways and maximize well-being at work by increasing structural and social resources and challenges and decreasing hindering demands. However, the evidence supporting this relationship is scant. This study sought to: 1) investigate to what extent residents possess job-crafting skills and compare residents' levels of job-crafting skills across years of residency training; 2) investigate the relationship between job crafting, well-being as measured by burnout and work-engagement rates, and the intention to leave; and 3) compare the levels of job-crafting skills and well-being between residents with and without serious intentions to leave. This cross sectional study was conducted in fifteen residency programs in Colombia. Surgical residents completed different questionnaires including the Dutch Job Crafting Scale (DJCS), MBI-Human Services Survey (MBI-HSS), Utrecht Work Engagement Scale (UWES-17) and an adapted version of the Nurse Turnover Intention Scale (NTIS). The objectives were addressed by independent analyses of variance (ANOVA), structural equation modeling techniques (SEM) and independent t-tests, respectively. A total of 202 residents participated. Residents generally scored high on their job-crafting skills to increase structural and social resources as well as challenging demands, but were less positive about their skills to reduce hindering demands. No differences across years of training were found. Job crafting correlated positively with work-engagement, which was inversely related to the intention to leave. Conversely, job crafting correlated negatively with burnout, which bore a positive relationship to the intention to leave. Residents with serious intentions to leave exhibited

Productive and counterproductive job crafting: A daily diary study.

Science.gov (United States)

Demerouti, Evangelia; Bakker, Arnold B; Halbesleben, Jonathon R B

2015-10-01

The present study aims to uncover the way daily job crafting influences daily job performance (i.e., task performance, altruism, and counterproductive work behavior). Job crafting was conceptualized as "seeking resources," "seeking challenges," and "reducing demands" and viewed as strategies individuals use to optimize their job characteristics. We hypothesized that daily job crafting relates to daily job demands and resources (work pressure and autonomy), which consequently relate to daily work engagement and exhaustion and ultimately to job performance. A sample of 95 employees filled in a quantitative diary for 5 consecutive working days (n occasions = 475). We predicted and found that daily seeking resources was positively associated with daily task performance because daily autonomy and work engagement increased. In contrast, daily reducing demands was detrimental for daily task performance and altruism, because employees lower their daily workload and consequently their engagement and exhaustion, respectively. Only daily seeking challenges was positively (rather than negatively) associated with daily counterproductive behavior. We conclude that employee job crafting can have both beneficial and detrimental effects on job performance. (c) 2015 APA, all rights reserved).

When craft and science collide: Improving therapeutic practices through evidence-based innovations.

Science.gov (United States)

Justice, Laura M

2010-04-01

Evidence-based practice (EBP) is a model of clinical decision-making that is increasingly being advocated for use in the field of speech-language pathology. With the increased emphasis on scientific evidence as a form of knowledge important to EBP, clinicians may wonder whether their craft-based knowledge (i.e., knowledge derived from theory and practice), remains a legitimate form of knowledge for use in clinician decisions. This article describes forms of knowledge that may be used to address clinical questions, to include both craft and science. Additionally, the steps used when engaging in EBP are described so that clinicians understand when and how craft comes into play. The major premise addressed within this article is that craft is a legitimate form of knowledge and that engagement in EBP requires one to employ craft-based knowledge.

Borcherding, J.D.; Sebastian, S.J.

1980-01-01

This paper reports on a research study whose objective was to determine the most influential factors adversely affecting craft productivity in nuclear power plant construction from the perspective of the tradesmen employed at the sites. Data were collected through the use of a questionnaire survey and group interview sessions, predominantly with workmen, at six nuclear power plant construction projects. Craftsmen were chosen as the major data base because of their awareness of how their time would actually be spent on the project. Topics considered include the factors influencing craft productivity, material availability, redoing work, crew interfacing, overcrowded work areas, instruction time, inspection delays, craft turnover, craft absenteeism, foreman changes, foreman incompetence, engineering design lead time, comprehensive scheduling of the design function, the responsibility of the utility, value engineering, plant standardization, the effective utilization of the planning and scheduling system, and the labor-management committee

Manually annotated corpora are critical for the training and evaluation of automated methods to identify concepts in biomedical text. This paper presents the concept annotations of the Colorado Richly Annotated Full-Text (CRAFT) Corpus, a collection of 97 full-length, open-access biomedical journal articles that have been annotated both semantically and syntactically to serve as a research resource for the biomedical natural-language-processing (NLP) community. CRAFT identifies all mentions of nearly all concepts from nine prominent biomedical ontologies and terminologies: the Cell Type Ontology, the Chemical Entities of Biological Interest ontology, the NCBI Taxonomy, the Protein Ontology, the Sequence Ontology, the entries of the Entrez Gene database, and the three subontologies of the Gene Ontology. The first public release includes the annotations for 67 of the 97 articles, reserving two sets of 15 articles for future text-mining competitions (after which these too will be released). Concept annotations were created based on a single set of guidelines, which has enabled us to achieve consistently high interannotator agreement. As the initial 67-article release contains more than 560,000 tokens (and the full set more than 790,000 tokens), our corpus is among the largest gold-standard annotated biomedical corpora. Unlike most others, the journal articles that comprise the corpus are drawn from diverse biomedical disciplines and are marked up in their entirety. Additionally, with a concept-annotation count of nearly 100,000 in the 67-article subset (and more than 140,000 in the full collection), the scale of conceptual markup is also among the largest of comparable corpora. The concept annotations of the CRAFT Corpus have the potential to significantly advance biomedical text mining by providing a high-quality gold standard for NLP systems. The corpus, annotation guidelines, and other associated resources are freely available at http://bionlp-corpora.sourceforge.net/CRAFT/index.shtml.

Automatic Generation of the Planning Tunnel High Speed Craft Hull Form

Morteza Ghassabzadeh; Hassan Ghassemi

2012-01-01

The creation of geometric model of a ship to determine the characteristics of hydrostatic and hydrodynamic,and also for structural design and equipments arrangement are so important in the ship design process.Planning tunnel high speed craft is one of the crafts in which,achievement to their top speed is more important.These crafts with the use of tunnel have the aero-hydrodynamics properties to diminish the resistance,good sea-keeping behavior,reduce slamming and avoid porpoising.Because of the existence of the tunnel,the hull form generation of these crafts is more complex and difficult.In this paper,it has attempted to provide a method based on geometry creation guidelines and with an entry of the least control and hull form adjustment parameters,to generate automatically the hull form of planning tunnel craft.At first,the equations of mathematical model are described and subsequent,three different models generated based on present method are compared and analyzed.Obviously,the generated model has more application in the early stages of design.

van Wingerden, Jessica; Niks, Irene M W

2017-01-01

We developed and validated a scale to measure employees' perceived opportunity to craft (POC) in two separate studies conducted in the Netherlands (total N = 2329). POC is defined as employees' perception of their opportunity to craft their job. In Study 1, the perceived opportunity to craft scale (POCS) was developed and tested for its factor structure and reliability in an explorative way. Study 2 consisted of confirmatory analyses of the factor structure and reliability of the scale as well as examination of the discriminant and criterion-related validity of the POCS. The results indicated that the scale consists of one dimension and could be reliably measured with five items. Evidence was found for the discriminant validity of the POCS. The scale also showed criterion-related validity when correlated with job crafting (+), job resources (autonomy +; opportunities for professional development +), work engagement (+), and the inactive construct cynicism (-). We discuss the implications of these findings for theory and practice.

Two-craft Coulomb formation study about circular orbits and libration points

Science.gov (United States)

Inampudi, Ravi Kishore

This dissertation investigates the dynamics and control of a two-craft Coulomb formation in circular orbits and at libration points; it addresses relative equilibria, stability and optimal reconfigurations of such formations. The relative equilibria of a two-craft tether formation connected by line-of-sight elastic forces moving in circular orbits and at libration points are investigated. In circular Earth orbits and Earth-Moon libration points, the radial, along-track, and orbit normal great circle equilibria conditions are found. An example of modeling the tether force using Coulomb force is discussed. Furthermore, the non-great-circle equilibria conditions for a two-spacecraft tether structure in circular Earth orbit and at collinear libration points are developed. Then the linearized dynamics and stability analysis of a 2-craft Coulomb formation at Earth-Moon libration points are studied. For orbit-radial equilibrium, Coulomb forces control the relative distance between the two satellites. The gravity gradient torques on the formation due to the two planets help stabilize the formation. Similar analysis is performed for along-track and orbit-normal relative equilibrium configurations. Where necessary, the craft use a hybrid thrusting-electrostatic actuation system. The two-craft dynamics at the libration points provide a general framework with circular Earth orbit dynamics forming a special case. In the presence of differential solar drag perturbations, a Lyapunov feedback controller is designed to stabilize a radial equilibrium, two-craft Coulomb formation at collinear libration points. The second part of the thesis investigates optimal reconfigurations of two-craft Coulomb formations in circular Earth orbits by applying nonlinear optimal control techniques. The objective of these reconfigurations is to maneuver the two-craft formation between two charged equilibria configurations. The reconfiguration of spacecraft is posed as an optimization problem using the

The effects of job crafting on subjective well-being amongst South African high school teachers

Directory of Open Access Journals (Sweden)

Sergio Peral

2016-09-01

Full Text Available Orientation: Job crafting can result in a number of positive outcomes for teachers, such as increased meaningfulness and engagement at work. Increased work engagement and psychological meaningfulness may yield positive benefits for the practice of teaching, thus highlighting the pivotal role of job crafting. Research purpose: The study’s aim was to investigate the relationship between job crafting and subjective well-being amongst South African high school teachers. Subjective well-being comprises psychological meaningfulness and work engagement. The potential mediating effect that psychological meaningfulness had on this relationship was further explored. Motivation for the study: Being in a highly stressful occupation, teachers need to continuously find ways to craft their working practices in order to deal effectively with their job demands and to capitalise on their available job resources. Furthermore, South Africa’s current education system calls for serious proactive measures to be taken to improve and rectify the current status, such as job crafting. Research approach, design and method: A quantitative, cross-sectional survey design was used and administered to a sample of South African high school teachers situated in Gauteng, South Africa (N = 251. Main findings: A positive relationship was found between job crafting (increasing structural resources and challenging job demands and work engagement. Furthermore, psychological meaningfulness mediated the relationship between job crafting and work engagement amongst the sampled high school teachers. Practical/managerial implications: Teachers who craft their work to better suit their preferences and needs will obtain greater meaning in their work and experience increased levels of work engagement. Training programmes and/or group-based interventions targeted around job crafting techniques may be particularly useful in the South African teaching context. Contribution/value-add: This

More than 200 pupils were asked to define, what are the most important skills for the pupils of their age. The results bring out that category of the skills related to craft subject is of the most presented categories in pupils' self description. Thus the primary school pupils essentially defined themselves by the activities they could do practically (building, cooking, repairing of things. The most undefined relation to craft activities is reflected in the answer of smaller boys in our study. A suspicion arisen from the analysis of pupils' sayings, that the craft lessons in the 1st school stage tend to be organized kind of poorly was asserted by the teachers who pointed out the need for special rooms and materials to implement different techniques.

Primary student teachers’ perceptions of their prior experiences with craft-making in light of Hannah Arendt’s human condition

Directory of Open Access Journals (Sweden)

Seija Karppinen

2013-09-01

Full Text Available This article presents the results of a study about student teachers’ feelings toward craft-making and teaching crafts. As a teacher educator in teacher training, my interest lies first in student teachers’ prior craft experiences and in their prejudices about themselves as craft-makers in relation to the human condition as set forth by philosopher Hannah Arendt (1958/2002. Second, I am interested in how students’ experiences and their image of crafts affect their attitude to crafts and teaching crafts. The study uses qualitative content analysis (e.g. Cohen, Manion & Morrison, 2007, concept clarification (e.g. Kramer, 1993; Burkin, 2011 and thought experiments (Zalta, 2011; Cohnitz, 2006; Sorensen, 1992 to identify and categorise student teachers’ emotional experiences. The data consist of essays (craft biographies, N=144 by first-year student teachers which were written in 2008 and 2009 during a basic course in crafts as part of teacher education at the University of Helsinki. Arendt (1958/2002 labelled the elements of the human condition as labour, work and action. In this study I discuss how, for instance, Arendtian concepts could be explained in relation to crafts, craft-making and education. Arendt categorises craft, defined as things made by hand, as part of the concept of work. In this study, I consider whether crafts and craft-making could be part of other Arendtian terms as well and how these terms fit various educational situations. As a result, there is a need for additional terms alongside Arendtian terms to describe multifaceted craft-making and primary student teachers’ perceptions of themselves as craft-makers. In relation to student teachers’ memories on primary school crafts, I have labelled Arendtian concept labour as students’ credit-orientated activity, the concept of work as making-orientated activity and the concept of action as interaction-orientated activity. These three orientations of craft frame student

Community Reinforcement and Family Training (CRAFT) assists family members with a treatment-resistant loved one. The most consistent outcome of CRAFT is increased treatment entry of the identified treatment-resistant person (IP). This led us to question whether all 6 components of CRAFT are necessary. In a randomized clinical trial, 115 concerned significant others (CSOs) of an IP received 12-14 sessions of the full CRAFT intervention, 4-6 sessions focused on Treatment Entry Training (TEnT), or 12-14 sessions of Al-Anon/Nar-Anon Facilitation (ANF). We monitored treatment entry, attendance, and substance use of the IP and the CSO's mood and functioning. Data were collected at baseline and 4, 6, and 9 months after the baseline. We found significant reductions in time to treatment entry (χ(2)2 = 8.89, p = .01) and greater treatment entry rates for CRAFT (62%; odds ratio [OR] = 2.7, 95% confidence interval [CI] = 1.1-6.9) and TEnT (63%; OR = 2.9, 95% CI = 1.2-7.5) compared with ANF (37%), but CRAFT and TEnT did not differ significantly from each other (OR = 1.1, 95% CI = 0.4-2.7). No between-group differences in IP drug use were reported by CSOs, but days of drug use decreased over time for all groups (F(3, 277) = 13.47, p CRAFT produces greater treatment entry rates than ANF and found similar treatment entry rates for CRAFT and TEnT. This suggests that treatment entry training is sufficient for producing the best established outcome of CRAFT. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

High Job Demands, Still Engaged and Not Burned Out? The Role of Job Crafting.

Science.gov (United States)

Hakanen, Jari J; Seppälä, Piia; Peeters, Maria C W

2017-08-01

Traditionally, employee well-being has been considered as resulting from decent working conditions arranged by the organization. Much less is known about whether employees themselves can make self-initiated changes to their work, i.e., craft their jobs, in order to stay well, even in highly demanding work situations. The aim of this study was to use the job demands-resources (JD-R model) to investigate whether job crafting buffers the negative impacts of four types of job demands (workload, emotional dissonance, work contents, and physical demands) on burnout and work engagement. A questionnaire study was designed to examine the buffering role of job crafting among 470 Finnish dentists. All in all, 11 out of 16 possible interaction effects of job demands and job crafting on employee well-being were significant. Job crafting particularly buffered the negative effects of job demands on burnout (7/8 significant interactions) and to a somewhat lesser extent also on work engagement (4/8 significant interactions). Applying job crafting techniques appeared to be particularly effective in mitigating the negative effects of quantitative workload (4/4 significant interactions). By demonstrating that job crafting can also buffer the negative impacts of high job demands on employee well-being, this study contributed to the JD-R model as it suggests that job crafting may even be possible under high work demands, and not only in resourceful jobs, as most previous studies have indicated. In addition to the top-down initiatives for improving employee well-being, bottom-up approaches such as job crafting may also be efficient in preventing burnout and enhancing work engagement.

Leader–member exchange fosters work engagement: The mediating role of job crafting

Directory of Open Access Journals (Sweden)

Mirjam Radstaak

2017-09-01

Full Text Available Orientation: The right balance between job demands and job resources are essential for employees to bring energy and enthusiasm to work. Employees who experience high-quality relationships with their supervisors may actively craft their job demands and job resources and feel more engaged. Research purpose: The current study examined the associations between leader–member exchange (LMX, job crafting and work engagement. Motivation: This study attempts to gain more insight in the associations between LMX, job crafting and work engagement. It was hypothesised that high-quality relationships with supervisors fosters work engagement because it stimulates employees to craft their jobs by increasing social and structural job resources and challenging job demands and by decreasing hindering job demands. Research approach, design and methodology: Participants (N = 402 working for a leading mail and parcels company in the Netherlands completed questionnaires measuring LMX, work engagement and job crafting. Structural equation modelling was used to examine the hypotheses. Main findings: Increasing social job resources (β = 0.01, SE = 0.00, p < 0.001 and increasing challenging job demands (β = 0.08, SE = 0.04, p < 0.05 were significant mediators in the association between LMX and work engagement. Increasing structural job resources (β = 0.00, SE = 0.00, p = 0.92 and decreasing hindering job demands (β = -0.00, SE 0.00, p = 0.09 were not significant mediators. Practical and managerial implications: Supervisors who are capable of building high-quality relationships with their employees based on trust, respect and loyalty will foster a positive, fulfilling work-related state of mind among employees because they are more willing to proactively craft a challenging and resourceful work environment. Contribution or value-add: The findings of this study showed the importance of high-quality relationships with supervisors and were unique in examining the

The Validity of the School Assessment in the Craft Subject

Directory of Open Access Journals (Sweden)

Antti Hilmola

2016-06-01

Full Text Available In this research project, the validity of the school assessment is examined in the craft subject in Finland’s basic education. The criteria for the school assessment are based on the Finnish Na-tional Core Curriculum (FNCC in which the idea of the Entire Craft (EC is highlighted. How-ever, the discussion as to whether or not the school practice is based on the idea of EC, or whether the teachers are still focused on the technical details of products in reflecting on the pupils’ tool-handling skills, is still an ongoing debate. Learner-centred learning is implicated in EC since the pupils are expected to set goals for the implementation of their own ideating, plan-ning and constructing. And, finally, in such a process, the self-reflection of the implemented out-comes against the goals will take place.  Altogether 73 craft teachers from 59 upper level schools participated in this research project. The pupils’ (N = 982 success was assessed during an EC period using the indicator validated by the previous nation-wide evaluation by the Finn-ish National Board of Education (FNBE. Since the valid school assessment was expected to reflect the success in the Entire Craft Assessment Period (ECAP, the outcomes were assessed against the criteria of the FNCC and compared to the pupils’ school scores. The data was ana-lysed using the Linear Regression Analysis (Enter Method. The central observation was that the pupils’ success in the criteria of the EC do not reflect the 7th grade school scores, in all re-spects. Moreover, the pupils’ success does not reflect the 6th grade school scores. The instruc-tions and supplementary education of the FNCC criteria are needed for craft teachers, especial-ly for class teachers at the lower level. In Finland, also the craft subject is taught by the class teachers at the lower level while, at the upper level, the subject teachers take their place. Ac-cording to the new FNCC, the number of class lessons will be

Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement ( β  = 0.31, p  engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

Alternative theoretical and methodological approaches for exploring higher education in Art and Crafts

Marte Sørebø Gulliksen

2009-12-01

Full Text Available This article presents and discusses approaches for exploring higher education in Art and Crafts. The concepts exploring versus research and the different foci in an insider perspective versus an outsider perspective introduces the theme. An insider perspective is said to be a useful starting point for inquiry, referring to Frayling’s trichotomy research into, research on and research through from 1993. The field of higher education in Art and Crafts education is shortly presented as comprising two main areas of knowledge: knowledge of education, and knowledge about the different subject areas within Art and Crafts. Both theory and practice are a part of these areas of knowledge. As higher education in Art and Crafts is a making profession, the most prominent challenge when exploring this today is thus said to be to develop research based knowledge on Education in Art and Crafts as a making discipline.  Two keywords are deemed to be useful in approaching this theme: Mode 2 knowledge production and transdisciplinarity. The article concludes with describing specific ways of doing this today from within the context of application. Two examples of large research projects in Scandinavia are presented as examples of such projects.

“Making our job hospitable” – Assessment of job-crafting behavior among dental academic faculty in South India

Directory of Open Access Journals (Sweden)

V Siva Kalyan

2018-01-01

Full Text Available Introduction: Employees are regularly offered opportunities to make their work more appealing and rewarding. These opportunities might be as simple as making fine changes to their daily tasks to boost happiness and to connect with more people at vocation. Hence, an attempt is made to assess job-crafting behavior among the dental academic faculty. Materials and Methods: A cross-sectional study was conducted among dental academic faculty from five dental colleges. Job Crafting Questionnaire (JCQ was used to assess the job-crafting behavior. Mean scores were calculated for different domains of JCQ. Gender differences were analyzed using Student's “t-” test and one-way ANOVA to test the difference between different academic positions of the faculty members. Results: A total of 228 dental faculty members with a mean age of 34.43 ± 6.13 years participated in the study. The mean value of job-crafting behavior was found to be highest among female faculty (60.07 ± 8.38 and professors (61.35 ± 8.30. Male faculty scored higher in task-crafting domain and female faculty scored higher in both cognitive- and relational-crafting domains. The professors scored highest in all the three domains of job-crafting behavior as compared to that of senior lecturers and readers. Conclusion: Job crafting is an effectual workplace intervention, where employees assume an active role in shaping their work experience to enhance their job satisfaction and well-being. The overall score of job-crafting behavior was found to be highest among both professors and female faculty members. Male faculty members scored higher in task-crafting domain. With regard to individual domains, the participants scored highest in cognitive crafting followed by task and relational crafting.

Application of CRAFT in two-dimensional NMR data processing.

Science.gov (United States)

Krishnamurthy, Krish; Sefler, Andrea M; Russell, David J

2017-03-01

Two-dimensional (2D) data are typically truncated in both dimensions, but invariably and severely so in the indirect dimension. These truncated FIDs and/or interferograms are extensively zero filled, and Fourier transformation of such zero-filled data is always preceded by a rapidly decaying apodization function. Hence, the frequency line width in the spectrum (at least parallel to the evolution dimension) is almost always dominated by the apodization function. Such apodization-driven line broadening in the indirect (t 1 ) dimension leads to the lack of clear resolution of cross peaks in the 2D spectrum. Time-domain analysis (i.e. extraction of frequency, amplitudes, line width, and phase parameters directly from the FID, in this case via Bayesian modeling into a tabular format) of NMR data is another approach for spectral resonance characterization and quantification. The recently published complete reduction to amplitude frequency table (CRAFT) technique converts the raw FID data (i.e. time-domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. CRAFT analyses of time-domain data require minimal or no apodization prior to extraction of the four parameters. We used the CRAFT processing approach for the decimation of the interferograms and compared the results from a variety of 2D spectra against conventional processing with and without linear prediction. The results show that use of the CRAFT technique to decimate the t 1 interferograms yields much narrower spectral line width of the resonances, circumventing the loss of resolution due to apodization.

Full Text Available Yogyakarta is one of Indonesia’s major tourist destinations. This is due to its nature, interesting, unique and fantastic ancient cultural and art sites. Creative industries and the ceramic crafts play an important role in the development of tourism in Yogyakarta. In this paper, ethnographic approach is used to describe the creative process and the ceramic crafts industry in the village of Kasongan, Yogyakarta. Based on the results of the field research, the authors conclude that the ceramic crafts tourist village of Kasongan is moving toward greater commoditization whereby the ceramics centre is now more oriented towards meeting the needs of tourist industry in Yogyakarta. Due to extensive interaction and the positive response from the general public, ceramic crafts practitioners of Kasongan experience unique and characteristic creative period. The crafters manage to negotiate between the old and the new values, in the village one can find both traditional pottery and new, creative and innovative ceramic products of export quality. Today, Kasongan is a trade mark ceramic tourism village that is entering the global era.

Different types of employee well-being across time and their relationships with job crafting.

Science.gov (United States)

Hakanen, Jari J; Peeters, Maria C W; Schaufeli, Wilmar B

2018-04-01

We used and integrated the circumplex model of affect (Russell, 1980) and the conservation of resources theory (Hobfoll, 1998) to hypothesize how various types of employee well-being, which can be differentiated on theoretical grounds (i.e., work engagement, job satisfaction, burnout, and workaholism), may differently predict various job crafting behaviors (i.e., increasing structural and social resources and challenging demands, and decreasing hindering demands) and each other over time. At Time 1, we measured employee well-being, and 4 years later at Time 2, job crafting and well-being, using a large sample of Finnish dentists (N = 1,877). The results of structural equation modeling showed that (a) work engagement positively predicted both types of increasing resources and challenging demands and negatively predicted decreasing hindering demands; (b) workaholism positively predicted increasing structural resources and challenging demands; (c) burnout positively predicted decreasing hindering demands and negatively predicted increasing structural resources, whereas (d) job satisfaction did not relate to job crafting over time; and (e) work engagement positively influenced job satisfaction and negatively influenced burnout, whereas (f) workaholism predicted burnout after controlling for baseline levels. Thus, work engagement was a stronger predictor of future job crafting and other types of employee well-being than job satisfaction. Although workaholism was positively associated with job crafting, it also predicted burnout. We conclude that the relationship between job crafting and employee well-being may be more complex than assumed, because the way in which employees will craft their jobs in the future seems to depend on how they currently feel.

Tracking Porters: Learning the Craft of Techno-Anthropology.

Science.gov (United States)

Bruun, Maja Hojer; Krause-Jensen, Jakob; Saltofte, Margit

2015-01-01

Anthropology attempts to gain insight into people's experiential life-worlds through long-term fieldwork. The quality of anthropological knowledge production, however, does not depend solely on the duration of the stay in the field, but also on a particular way of seeing social situations. The anthropological perspective is grounded in socio-cultural theory and forged by a distinct relativist or contextualist epistemological stance. The point is to understand events, concepts and phenomena from the insiders' point of view and to show how this view relates to the particular social and cultural context. In this chapter, we argue that although anthropology has its specific methodology - including a myriad of ethnographic data-gathering tools, techniques, analytical approaches and theories - it must first and foremost be understood as a craft. Anthropology as craft requires a specific 'anthropological sensibility' that differs from the standardized procedures of normal science. To establish our points we use an example of problem-based project work conducted by a group of Techno-Anthropology students at Aalborg University, we focus on key aspects of this craft and how the students began to learn it: For two weeks the students followed the work of a group of porters. Drawing on anthropological concepts and research strategies the students gained crucial insights about the potential effects of using tracking technologies in the hospital.

Job crafting in changing organizations: Antecedents and implications for exhaustion and performance.

Science.gov (United States)

Petrou, Paraskevas; Demerouti, Evangelia; Schaufeli, Wilmar B

2015-10-01

The present study addressed employee job crafting behaviors (i.e., seeking resources, seeking challenges, and reducing demands) in the context of organizational change. We examined predictors of job crafting both at the organizational level (i.e., perceived impact of the implemented changes on the working life of employees) and the individual level (i.e., employee willingness to follow the changes). Job crafting behaviors were expected to predict task performance and exhaustion. Two-wave longitudinal data from 580 police officers undergoing organizational changes were analyzed with structural equation modeling. Findings showed that the degree to which changes influence employees' daily work was linked to reducing demands and exhaustion, whereas employee willingness to change was linked to seeking resources and seeking challenges. Furthermore, while seeking resources and seeking challenges were associated with high task performance and low exhaustion respectively, reducing demands seemed to predict exhaustion positively. Our findings suggest that job crafting can act as a strategy of employees to respond to organizational change. While seeking resources and seeking challenges enhance employee adjustment and should be encouraged by managers, reducing demands seems to have unfavorable implications for employees.

Emotions in Risk Assessment and Decision Making Processes During Craft Practice

Directory of Open Access Journals (Sweden)

Camilla Groth

2015-12-01

Full Text Available Traditionally subjective experiences and emotions have been overlooked in the practice of scientific research. In the field of design and craft research too, feelings and emotions have been considered as interfering with the rigour of research. However, as a result of findings in neuroscience, a new understanding has emerged, providing emotions a central role in risk assessment and decision making processes. This has implications also for how we understand craft practice. In this practice-led research, a craft practitioner analysed five video-recordings of herself while throwing clay blindfolded. The researcher-practitioner specifically studied critical incidents in the throwing process and made a detailed analysis of how sensory experiences and emotions guided her in risk assessment, decision making, and problem solving during the clay-throwing sessions. She found that her tactile experience gave her important clues on the condition of the material and its consequent possibilities at different stages. These experiences in turn affected her emotions in either positive or negative ways, affecting her risk assessment, decision making, and problem solving activities. This research has shown that sensory experiences and emotions influence the craft making process and are thus important elements in the expertise of the craftsperson. The role of such emotions remains to be studied further in the expertise of researchers in general.

Lin, Y. C.; Wu, T. C.; Hsu, M. F.

2013-07-01

Caisson is one of the important representations of the Minnan (southern Fujian) temple architecture craft techniques and decorative aesthetics. The special component design and group building method present the architectural thinking and personal characteristics of great carpenters of Minnan temple architecture. In late Qing Dynasty, the appearance and style of caissons of famous temples in Taiwan apparently presented the building techniques of the great carpenters. However, as the years went by, the caisson design and craft techniques were not fully inherited, which has been a great loss of cultural assets. Accordingly, with the caisson of Fulong temple, a work by the well-known great carpenter in Tainan as an example, this study obtained the thinking principles of the original design and the design method at initial period of construction through interview records and the step of redrawing the "Tng-Ko" (traditional design, stakeout and construction tool). We obtained the 3D point cloud model of the caisson of Fulong temple using 3D laser scanning technology, and established the 3D digital model of each component of the caisson. Based on the caisson component procedure obtained from interview records, this study conducted the digital simulation of the caisson component to completely recode and present the caisson design, construction and completion procedure. This model of preserving the craft techniques for Minnan temple caisson by using digital technology makes specific contribution to the heritage of the craft techniques while providing an important reference for the digital preservation of human cultural assets.

The oil spill which occurred recently in the Gulf of Mexico highlighted the lack of efficient oil spill clean-up equipment for an offshore environment. With the increase in industrial operations in the Arctic Seas it is of high importance to develop an efficient oil spill response as the absence of reliable oil spill contingency plans will not be tolerated in such environmentally sensitive areas. The aim of this paper is to present the use of the ARKTOS amphibious craft for cleaning up an oil spill in the Arctic. This craft is usually used for logistical services and evacuation purposes; its use for clean-up purposes has been under study since 2000. This study showed that the ARKTOS craft could be an efficient means for oil spill clean-up in the Arctic because of its proven ice capable amphibious platforms and its hydraulic power; however oil collection trials should be performed to validate it.

Sarawak Bamboo Craft: Symbolism and Phenomenon

Directory of Open Access Journals (Sweden)

Arshad Mohd Zaihidee

2014-04-01

Full Text Available The relationship between human beings and their environment has stirred reactions between nature and the development of mind and actions that can be discussed using interdisciplinary approaches such as psychology, sociology, anthropology and history, in understanding human thinking and behavior. A psychological approach is intended to evaluate the individual choices and needs in society. A sociological approach details the various patterns in the social organization. An anthropological approach is tied with culture and belief to fulfil human needs which are based on their habitat, while a historical approach looks at the development which is related to the past. Dimensions of experiences, order and logic, selective elaboration and expressions are used to analyze the bamboo craft of Iban, Melanau and Bidayuh societies in Sarawak long-houses. The existence of constitutive, moral, expressive and cognitive symbols has been interpreted based on a theoretical framework that has been developed by Langer Art Theory, Parsons Social Theory and Kaplan Culture Theory. The values and meaning formed are interpreted to understand matters related to the lives of villagers and the finding suggests that bamboo craft expresses the multi-ethnic mind and character in the socio-culture of long- houses in Sarawak.

Purpose and pleasure in late life: Conceptualising older women's participation in art and craft activities.

Liddle, Jeannine L M; Parkinson, Lynne; Sibbritt, David W

2013-12-01

The fourth age, as the last stage of life, represents a final challenge to find personal meaning in the face of changing capacities, illness and disability. Participation in valued activities is important for sustaining interest in life and has been associated with enhanced health and well-being. Art and craft activities are a popular form of participation amongst women in late life with growing international interest in the potential for these types of activities to maintain health and well-being and address problems of social isolation. Drawing on open text comments from 114 women enrolled in the Australian Longitudinal Study on Women's Health and in-depth interviews with 23 women all aged in their eighties, this paper explores the nature of older women's participation in art and craft activities and conceptualises links between participation in these activities and health and well-being in late life. Participation in art and craft activities is complex and dynamic, comprising cognitive and physical processes infused with emotion and occurs in the context of social relationships, physical spaces, physical ailments and beliefs about the value of the activities. By participating in art and craft activities, older women find purpose in their lives, contributing to their subjective well-being whilst helping and being appreciated by others. They develop a self view as enabled and as such take on new art and craft challenges, continue to learn and develop as art and craft makers and remain open to new possibilities. © 2013.

Job crafting and its impact on work engagement and job satisfaction in mining and manufacturing

Directory of Open Access Journals (Sweden)

Leon T de Beer

2016-09-01

Full Text Available The purpose of this study was to investigate job crafting and its relationship with work engagement and job satisfaction within the South African context. This research is important as job crafting has been shown to have a positive influence on employee motivation. A cross-sectional survey design was used to collect primary data from organisations in the mining and manufacturing industries of South Africa (N = 470. The results of multi-group structural equation modelling showed that the original four-factor structure of the job crafting scale was supported by the data, but that a three-factor structure was necessary due to a discriminant validity concern regarding two job crafting dimensions. Regression results revealed that increasing structural job resources with challenging job demands, and increasing social job resources were significant predictors of work engagement in both groups. Contrary to expectations decreasing hindering job demands was a negative predictor of job satisfaction in the mining group. Furthermore, increasing social job resources was also a significant predictor of job satisfaction in both groups. This study indicates the importance of job crafting for work engagement and job satisfaction in organisations.

Classification of radiolarian images with hand-crafted and deep features

Science.gov (United States)

Keçeli, Ali Seydi; Kaya, Aydın; Keçeli, Seda Uzunçimen

2017-12-01

Radiolarians are planktonic protozoa and are important biostratigraphic and paleoenvironmental indicators for paleogeographic reconstructions. Radiolarian paleontology still remains as a low cost and the one of the most convenient way to obtain dating of deep ocean sediments. Traditional methods for identifying radiolarians are time-consuming and cannot scale to the granularity or scope necessary for large-scale studies. Automated image classification will allow making these analyses promptly. In this study, a method for automatic radiolarian image classification is proposed on Scanning Electron Microscope (SEM) images of radiolarians to ease species identification of fossilized radiolarians. The proposed method uses both hand-crafted features like invariant moments, wavelet moments, Gabor features, basic morphological features and deep features obtained from a pre-trained Convolutional Neural Network (CNN). Feature selection is applied over deep features to reduce high dimensionality. Classification outcomes are analyzed to compare hand-crafted features, deep features, and their combinations. Results show that the deep features obtained from a pre-trained CNN are more discriminative comparing to hand-crafted ones. Additionally, feature selection utilizes to the computational cost of classification algorithms and have no negative effect on classification accuracy.

NATURAL BASES AND ARTISTIC MEANS OF MODERN ARTS AND CRAFTS OF DAGESTAN

Directory of Open Access Journals (Sweden)

G. G. Gazimagomedov

2015-01-01

Full Text Available The aim is to carry out a generalized analysis of the history of formation of a new artistic language in contemporary arts and crafts of Dagestan. An innovative search for applied artist has gained further development in a series of works of the leading masters of folk arts and crafts of Dagestan. Discussion. For millennia, arts and crafts of Dagestan have been organically linked with the life of people and their everyday way of life and daily activities, with their worldview and understanding of beauty. In the middle of the 1st millennium BC in the mountainous Dagestan, art of bronze casting has reached a high degree of perfection, most vividly represented by statues of different wild and domestic animals. Images of animals are interpreted generically, without study of small details, but with the characteristic features of the exterior. Paired images of birds are often found in the arts and crafts of the medieval Dagestan. This heraldic composition, two-part or in conjunction with the sacred tree - a three-part, presented in metal-plastic and carved stone and wood, was one of the most popular and enduring decorative items that was common during the Middle Ages and has survived to the present day. This also has been further developed and improved and inherited by craftsmen of Dagestan.Conclusion. When creating works of arts and crafts craftsmen use diverse traditional arts and engineering techniques, the ancient but substantially revised and reinterpreted iconic scenes and ornamental motifs. In art, folk craftsmen emphasize the unity of man and nature. Most ornamental motifs common in Dagestan, go back to the very specific nature prototypes. Compositional structure, as the artistic analysis shows, is often borrowed from nature. This feeling becomes a condition for cultural and biological development, acting as a factor of co-evolution of man and nature.

The data presented in this article is an original data on "Investigating the role of onsite learning in the optimisation of craft gang's productivity in the construction industry". This article describes the constraints influencing craft gang's productivity and the influence of onsite learning on the blockwork craft gang's productivity. It also presented the method of data collection, using a semi-structured interview and an observation method to collect data from construction organisations. We provided statistics on the top most important constraints affecting the craft gang's productivity using 3-D Bar charts. In addition, we computed the correlation coefficients and the regression model on the influence of onsite learning on craft gang's productivity using the man-hour as the dependent variable. The relationship between blockwork inputs and cycle numbers was determined at 5% significance level. Finally, we presented data information on the application of the learning curve theory using the unit straight-line model equations and computed the learning rate of the observed craft gang's blockwork repetitive work.

3D DIGITAL SIMULATION OF MINNAN TEMPLE ARCHITECTURE CAISSON'S CRAFT TECHNIQUES

Directory of Open Access Journals (Sweden)

Y. C. Lin

2013-07-01

Full Text Available Caisson is one of the important representations of the Minnan (southern Fujian temple architecture craft techniques and decorative aesthetics. The special component design and group building method present the architectural thinking and personal characteristics of great carpenters of Minnan temple architecture. In late Qing Dynasty, the appearance and style of caissons of famous temples in Taiwan apparently presented the building techniques of the great carpenters. However, as the years went by, the caisson design and craft techniques were not fully inherited, which has been a great loss of cultural assets. Accordingly, with the caisson of Fulong temple, a work by the well-known great carpenter in Tainan as an example, this study obtained the thinking principles of the original design and the design method at initial period of construction through interview records and the step of redrawing the "Tng-Ko" (traditional design, stakeout and construction tool. We obtained the 3D point cloud model of the caisson of Fulong temple using 3D laser scanning technology, and established the 3D digital model of each component of the caisson. Based on the caisson component procedure obtained from interview records, this study conducted the digital simulation of the caisson component to completely recode and present the caisson design, construction and completion procedure. This model of preserving the craft techniques for Minnan temple caisson by using digital technology makes specific contribution to the heritage of the craft techniques while providing an important reference for the digital preservation of human cultural assets.

Full Text Available AbstractJob crafting behavior refers to the changes made by workers in their job context for adjusting their activities to their preferences. We sought to adapt and collect validity evidences of the Job Crafting Behaviors Scale for the Brazilian context, in a sample of 491 workers, with a mean age of 26.7 years. Factor analysis revealed that the final instrument consisted of three dimensions (increasing structural job resources, increasing social job resources, increasing challenging job demands, which showed good internal consistency indexes. These dimensions showed low or moderate correlations with work engagement, positive psychological capital, positive job affect, and in-role performance. The scale showed evidence of validity, the use of which is recommended for future research on the changes that people make in their jobs.

Job Crafting: Older Workers’ Mechanism for Maintaining Person-Job Fit

Science.gov (United States)

Wong, Carol M.; Tetrick, Lois E.

2017-01-01

Aging at work is a dynamic process. As individuals age, their motives, abilities and values change as suggested by life-span development theories (Lang and Carstensen, 2002; Kanfer and Ackerman, 2004). Their growth and extrinsic motives weaken while intrinsic motives increase (Kooij et al., 2011), which may result in workers investing their resources in different areas accordingly. However, there is significant individual variability in aging trajectories (Hedge et al., 2006). In addition, the changing nature of work, the evolving job demands, as well as the available opportunities at work may no longer be suitable for older workers, increasing the likelihood of person-job misfit. The potential misfit may, in turn, impact how older workers perceive themselves on the job, which leads to conflicting work identities. With the traditional job redesign approach being a top-down process, it is often difficult for organizations to take individual needs and skills into consideration and tailor jobs for every employee (Berg et al., 2010). Therefore, job crafting, being an individualized process initiated by employees themselves, can be a particularly valuable mechanism for older workers to realign and enhance their demands-abilities and needs-supplies fit. Through job crafting, employees can exert personal agency and make changes to the task, social and cognitive aspects of their jobs with the goal of improving their work experience (Wrzesniewski and Dutton, 2001). Building on the Life Span Theory of Control (Heckhausen and Schulz, 1995), we posit that job crafting, particularly cognitive crafting, will be of increasing value as employees age. Through reframing how they think of their job and choosing to emphasize job features that are personally meaningful, older workers can optimize their resources to proactively redesign their jobs and maintain congruent, positive work identities.

A review of new developments in the Friedel–Crafts alkylation – From green chemistry to asymmetric catalysis

Directory of Open Access Journals (Sweden)

Magnus Rueping

2010-01-01

Full Text Available The development of efficient Friedel–Crafts alkylations of arenes and heteroarenes using only catalytic amounts of a Lewis acid has gained much attention over the last decade. The new catalytic approaches described in this review are favoured over classical Friedel–Crafts conditions as benzyl-, propargyl- and allyl alcohols, or styrenes, can be used instead of toxic benzyl halides. Additionally, only low catalyst loadings are needed to provide a wide range of products. Following a short introduction about the origin and classical definition of the Friedel–Crafts reaction, the review will describe the different environmentally benign substrates which can be applied today as an approach towards greener processes. Additionally, the first diastereoselective and enantioselective Friedel–Crafts-type alkylations will be highlighted.

The Craft of Scientific Writing uses scores of examples to show the differences between scientific writing that informs and persuades and scientific writing that does not. Focusing on technical papers, dissertations, and reports, this text shows engineers, scientists, and technical professionals the five keys of style that distinguish the best scientific documents: (1) having the details presented in a methodical fashion, (2) having the important details emphasized, (3) having ideas cast into clear and precise sentences, (4) having clear connections between those ideas, and (5) having illustrations that persuade.

Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being such as work engagement. This study examined the effectiveness of a newly developed job crafting intervention program on work engagement (as primary outcome), as well as job crafting and psychological distress (as secondary outcomes), using a pretest-posttest study design among Japanese employees. Participants were managers of a private company and a private psychiatric hospital in Japan. The job crafting intervention program consisted of two 120-min sessions with a two-week interval between them. Outcomes were assessed at baseline (Time 1), post-intervention (Time 2), and a one-month follow-up (Time 3). The mixed growth model analyses were conducted using time (Time 1, Time 2, and Time 3) as an indicator of intervention effect. Effect sizes were calculated using Cohen's d. The program showed a significant positive effect on work engagement (t = 2.20, p = 0.03) in the mixed growth model analyses, but with only small effect sizes (Cohen's d = 0.33 at Time 2 and 0.26 at Time 3). The program also significantly improved job crafting (t = 2.36, p = 0.02: Cohen's d = 0.36 at Time 2 and 0.47 at Time 3) and reduced psychological distress (t = -2.06, p = 0.04: Cohen's d = -0.15 at Time 2 and -0.31 at Time 3). The study indicated that the newly developed job crafting intervention program was effective in increasing work engagement, as well as in improving job crafting and decreasing psychological distress, among Japanese managers.

Full Text Available In a holistic craft process, the same person designs a visual and technical appearance, produces the design with craft materials and technologies, make necessary changes to the design during its production and finally assesses the process and the finished product. Similarly, in the educational context, students should make craft products starting with the design process. These kinds of designing and hands-on activities nurture students’ creativity and problem-solving skills and offer them an opportunity to test their ideas and see them realised. Testing and further developing pedagogical approaches to holistic craft is important from the perspective of the renewal of the national core curriculum (2016 in Finland, which emphasises holistic approaches and the integration of different content areas. This study presents an experiential learning model of combining literature education, ethic-moral education and craft. Kolb’s model of experiential learning gives a solid and systematic theoretical base for this LCE model (one combining literature, craft and ethic-moral education. The teaching experiment is implemented as a craft process supported with children’s literature and activities based on a story. It seems that children can derive benefit from literature and activities during a craft making process. In addition, referencing literature enables the teacher to combine the craft process with multiple learning targets, fostering both ethical and content skills. We present the LCE model both in the light of an experiential learning model and the pragmatic implementations it gives rise to. According to our experiments, experiential learning can be meaningfully applied to the holistic craft process and craft education. Furthermore, the LCE model helps students to commit to holistic craft by nurturing a personal attachment.

Emilio Lucio-Villegas

2018-04-01

Full Text Available The main aim of this article is to describe an ongoing study to recover the memories of the people and the traditional crafts associated with the Guadalquivir River where it passes through a town called C., 12km from the city of S. in the south of Spain. It seems that people are losing their sense of belonging to both a symbolic and geographical territory. The process for recovering it can be considered a generator of experiences and learning. These experiences are related to identity as an element which enables people to understand how individuals establish relationships amongst themselves and with the environment. The paper describes the process of research based on interviewing people to capture their experiences. This is a work in process. The first outcomes are related to a number of descriptive categories such as: the crafts associated with the River; the use of the River to transport goods and people; the family ties associated with the crafts; the cosmopolitanism of the people and the changes ensuing from it; the role of women; and the River as a magical and mysterious place. Preliminary conclusions call on us to consider the importance of recovering traditional crafts as a source of adult education, and of maintaining a cultural identity threatened by globalisation processes.

BioCraft: Using Gamification to Stimulate Students' Motivation and Acquisition of Scientific Terms in a Bilingual Classroom

Science.gov (United States)

Turner, Kent Alan

Gamification is the act of introducing game elements in any aspect of life. In this case, it is a classroom. The operating model of BioCraft was a role-playing game that reinforced deaf students' use of new vocabulary in a gamified environment. BioCraft addressed the problem of deaf students acquiring scientific terms and using these scientific terms bilingually in academic language. BioCraft also established a student-centered learning atmosphere that promoted intersubjectivity, appropriation, and self-determination. In BioCraft, students became avatars of new organisms living on a new planet who needed to learn about living systems, adaptations, and genetics in order to survive. The results of the operating model suggested that gamification had an effect on deaf students' motivation and frequency of using new scientific terms with minimal persuasion from the teacher.

Full Text Available External factors such as blurring market boundaries, escalating customer diversity and increasing global competitive threats have forced businesses to build strategies around key products and formulate market-driven strategies that are integrated with relationship and supply chain strategies to deliver superior customer value. Indeed, in the modern era of supply chain management, organisations are getting more integrated with their suppliers and customers as a way to manage the total supply chain. The purpose of this research was to determine if product strategies and supply chain practices of small craft business are aligned. Personal in-depth interviews were conducted with nine craft businesses operating in Gauteng Province, South Africa. The findings revealed that craft businesses struggle to match their product strategies with their supply chain strategies. Craft businesses also exhibited some inbound supply chain weaknesses.

Full Text Available Ecotourism has been growing in Yogyakarta that can be seen through the development of rural tourism. The development of rural tourism has positive impact to improve local community’s welfare nevertheless, it has also negative impact onto environmental carrying capacity. Lopati tourism village is located in Bantul, Yogyakarta, relying on traditional craft industry as tourism attraction. Traditional crafts are livelihood of local residents, so that environmental management efforts become part of their daily lives. This research aims to review the roles of community to reduce environmental impacts through analyzing the waste management of traditional craft industry. It used case study method to examine the uniqueness of Lopati village. Data collecting used participatory action research techniques in order to gather information from residents. Community participation acted to anticipate negative impact on development of rural tourism.  Waste management in Lopati committed by local residents not to cause adverse environmental impacts. The result show that waste management based on community participation supports the development of rural tourism.

Application of CRAFT (complete reduction to amplitude frequency table) in nonuniformly sampled (NUS) 2D NMR data processing.

Krishnamurthy, Krish; Hari, Natarajan

2017-09-15

The recently published CRAFT (complete reduction to amplitude frequency table) technique converts the raw FID data (i.e., time domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. It offers an alternate approach to decimate time-domain data, with minimal preprocessing step. It has been shown that application of CRAFT technique to process the t 1 dimension of the 2D data significantly improved the detectable resolution by its ability to analyze without the use of ubiquitous apodization of extensively zero-filled data. It was noted earlier that CRAFT did not resolve sinusoids that were not already resolvable in time-domain (i.e., t 1 max dependent resolution). We present a combined NUS-IST-CRAFT approach wherein the NUS acquisition technique (sparse sampling technique) increases the intrinsic resolution in time-domain (by increasing t 1 max), IST fills the gap in the sparse sampling, and CRAFT processing extracts the information without loss due to any severe apodization. NUS and CRAFT are thus complementary techniques to improve intrinsic and usable resolution. We show that significant improvement can be achieved with this combination over conventional NUS-IST processing. With reasonable sensitivity, the models can be extended to significantly higher t 1 max to generate an indirect-DEPT spectrum that rivals the direct observe counterpart.

Spent yeast from craft beers often includes more hops (Humulus lupulus L.) secondary metabolites than traditional recipes. These compounds include α- and β- acids, which are antimicrobial to the rumen hyper ammonia-producing bacteria (HAB) that are major contributors to amino acid degradation. The objective was to determine if the hops acids in spent craft brewer's yeast (CY; ~ 3·5 mg g(-1) hops acids) would protect it from degradation by caprine rumen bacteria and HAB when compared to a baker's yeast (BY; no hops acids). Cell suspensions were prepared by harvesting rumen fluid from fistulated goats, straining and differential centrifugation. The cells were re-suspended in media with BY or CY. After 24 h (39°C), HAB were enumerated and ammonia was measured. Fewer HAB and less ammonia was produced from CY than from BY. Pure culture experiments were conducted with Peptostreptococcus anaerobiusBG1 (caprine HAB). Ammonia production by BG1 from BY was greater than from CY. Ammonia production was greater when exogenous amino acids were included, but similar inhibition was observed in CY treatments. These results indicate that rumen micro-organisms deaminated the amino acids in CY to a lesser degree than BY. Spent brewer's yeast has long been included in ruminant diets as a protein supplement. However, modern craft beers often include more hops (Humulus lupulus L.) than traditional recipes. These compounds include α- and β- acids, which are antimicrobial to the rumen hyper ammonia-producing bacteria (HAB) that are major contributors to amino acid degradation. This study demonstrated that hops acids in spent craft brewer's yeast protected protein from destruction by HABin vitro. These results suggest that the spent yeast from craft breweries, a source of beneficial hops secondary metabolites, could have value as rumen-protected protein. Published 2016.

Hypnobirth within the NHS: time to ditch the parent craft?

Science.gov (United States)

Gavin-Jones, Teri

2016-05-01

Antenatal education within the National Health Service (NHS) is a service in decline within some hospital trusts. Classes on offer are being moved into online formats or discontinued completely. Whilst research into antenatal education remains limited, what is known is that good birth preparation is of value. "Participative preparation for childbirth can enhance women's overall satisfaction with the childbirth experience" (Schrader McMillan et al 2009: 49). There are pockets of excellent antenatal education within the NHS, but no system for regulating the quality and content. Traditional 'parent craft' classes can be oversubscribed, turning what should be a participative group into an audience. Offering good quality antenatal education has the potential to increase normality, improve the birth outcome and the experience of both woman and her birth partner. Is it time to ditch the parent craft and implement dynamic woman-focused education?

CRAFTING THE MICROWORLD: HOW ROBERT HOOKE CONSTRUCTED KNOWLEDGE ABOUT SMALL THINGS.

Science.gov (United States)

Lawson, Ian

2016-03-20

This paper investigates the way in which Robert Hooke constructed his microscopical observations. His Micrographia is justifiably famous for its detailed engravings, which communicated Hooke's observations of tiny nature to his readers, but less attention has been paid to how he went about making the observations themselves. In this paper I explore the relationship between the materiality of his instrument and the epistemic images he produced. Behind the pictures lies an array of hidden materials, and the craft knowledge it took to manipulate them. By investigating the often counter-theoretical and conflicting practices of his ingenious microscope use, I demonstrate the way in which Hooke crafted the microworld for his readers, giving insight into how early modern microscopy was understood by its practitioners and audience.

The role of big five factors on predicting job crafting propensities amongst administrative employees in a South African tertiary institution

Clement Bell

2016-04-01

Full Text Available Orientation: Personality provides a foundation for understanding employee job behaviours. It determines and reflects how they respond to their work situations. There is a shortage of previous researches that have specifically dealt with the predictive role of personality on job crafting. Job crafting is also a significantly new concept in the South African work context. It has both positive and negative consequences on employee job behaviours. Research purpose: The present study investigated the role of big five factors on predicting job crafting propensities amongst administrative employees in Alice, South Africa. Motivation for the study: The present study aimed to determine the role of big five factors on predicting job crafting propensities amongst administrative employees. It was premised on previous research that the big five factors are associated with many employee job behaviours. Research approach, design and method: The present study employed a quantitative, crosssectional research design with a sample of 246 administrative employees in Alice, South Africa. A biographical questionnaire, a Big Five Inventory, and a job crafting questionnaire were used to collect data. Main findings: The findings showed that big five factors of Conscientiousness, Extraversion, Agreeableness, Openness to experience and Neuroticism play a significant role in predicting job crafting propensities. Practical implications: The present study suggests that big five factors of Conscientiousness, Extraversion, Agreeableness, Openness to experience and Neuroticism have a predictive role on job crafting behaviours. Managers of tertiary institutions can therefore consider these big five personalities to understand and predict the impacts of their job design strategies on administrative employees’ behaviours. Contribution: The contribution of the study was significant in that it contributed to research literature representing the influence of the big five factors in

Comparison of Survival and Safety Requirements in European Union for Recreational Craft Inspections. A Spanish Case Study

Directory of Open Access Journals (Sweden)

J. Torralbo

2014-03-01

Full Text Available Statistical data shows that a large number of maritime accidents are related to recreational craft. For instance, in Spain, more than fifty percent of the emergencies are related to pleasure boats at sea. Recreational craft marketed in the EU must comply with harmonized technical safety and environmental requirements defined by Directive 94/25/EC, as amended in 2003. On 28 December 2013, the new recreational craft directive 2013/53/EU was published in the Official Journal of the European Union. EU Member States have until 18 January 2016 to amend their national legislation and transpose the new directive. The current directive 94/25/EC as amended by directive 2003/44/EC will be repealed on 18 January 2016, after the full application of the new text. Although this directive, there is not a clear coordination and equivalence among the EU countries according to the survival and safety equipment compulsory for recreational crafts. The main purpose of this paper is to analyze and compare the types of survey / inspections to be carried in pleasure craft (non-commercial use, periodicity and required safety equipment in some member states of the European Union. A case study of Spain is presented. From the results obtained, we can make clear that in the European Union there is a lack of coordination in this area and indicate the need to unify a common pattern in inspections and survival and safety requirements of recreational boats in the EU.

Noble gas control room accident filtration system for severe accident conditions (N-CRAFT)

International Nuclear Information System (INIS)

Hill, Axel; Stiepani, Cristoph; Drechsler, Michael

2015-01-01

Severe accidents might cause the release of airborne radioactive substances to the environment of the NPP either due to containment leakages or due to intentional filtered containment venting. In the latter case aerosols and iodine are retained, however noble gases are not retainable by the FCVS or by conventional air filtration systems like HEPA filters and iodine absorbers. Radioactive noble gases nevertheless dominate the activity release depending on the venting procedure and the weather conditions. To prevent unacceptable contamination of the control room atmosphere by noble gases, AREVA GmbH has developed a noble gas control room accident filtration system (CRAFT) which can supply purified fresh air to the control room without time limitation. The retention process is based on dynamic adsorption of noble gases on activated carbon. The system consists of delay lines (carbon columns) which are operated by a continuous and simultaneous adsorption and desorption process. CRAFT allows minimization of the dose rate inside the control room and ensures low radiation exposure to the staff by maintaining the control room environment suitable for prolonged occupancy throughout the duration of the accident. CRAFT consists of a proven modular design either transportable or permanently installed. (author)

Full Text Available Orientation: Knowing that it is imperative to better understand the antecedents and consequences of needs-supplies fit, the present research had two main objectives. Firstly we wanted to extend our knowledge about traditional psychological needs, for example highlighted through the Self-Determination Theory, by presenting more specific work-related needs. Secondly, following the new directions of organisational fit theories, we wanted to better understand how individuals make sense of fit. Research purpose: The purpose of this study is to propose more specific work-related needs in terms of employment quality and to test job crafting as an antecedent of needs-supplies fit (NS fit. We tested the double mediating role of NS fit (i.e. specific: based on more specific work-related needs, and general: based on global job perceptions between job crafting and individual outcomes namely burnout and work engagement. Motivation for the study: By taking into account more specific work-related needs, this study aimed to add more specific information to better help predict well-being at work. Moreover, the present research responds to the need to better understand how individuals make sense of fit. Research design, approach, and method: Data were collected in a Belgian Public Federal Service (N = 1500. Our research model was tested using Structural Equation Modelling with Mplus. Main findings: Results show, (1 that specific NS fit perception was positively related to a global NS fit perception and (2 the partial mediating role (specific and general of NS fit between job crafting and burnout and work engagement. Practical/managerial implications: Managers should encourage crafting behaviours and should know their team and that team’s specific needs. Contribution/added-value: By taking into account more specific work-related needs, our study suggests that needs-supplies may have more than one dimension. Moreover, it shows that job crafting is a way to

Indonesia has plenty of abundant natural wealth. This natural wealth produces natural materials that can be utilized as a craft product. The craft workers generally still work manually and the work is done repeatedly in one cycle so it is very susceptible to musculoskeletal disorders. Musculoskeletal disorders will cause decrease of worker’s effectiveness and efficiency in completing the task. Thus, this fact has some adverse impact for the company. The purpose of this study is to analyze some task in manufacturing a traditional cooking tool (griddle) which encompasses mold of the griddle, refine of the griddle and the finishing touch by using the Occupational Repetitive Action Index (OCRA index) method. This method consists of high frequency movements, large forces, awkward postures, insufficient resting time and other factor such as vibration. Result of this study shows that in the molding operation, the worker has uncertain and medium risk on right hand in manufacturing small and large size of griddle with OCRA index is 2.5 and 5.3 respectively. In the refining operation the worker has light and medium risk on left hand in manufacturing small and large size with OCRA index is 3.6 and 5.8 using grinding machine and 5.8, 5.2, 6.3 and 5.0 using miser tool. In finishing operation, the worker has high risk on right hand in numbering of code griddle and has medium risk on right hand and medium on left hand in labeling with OCRA index is 9, 6.1 and 6.8 While in assembling operation the worker has no risk. Score that it indicates the risk level of the task in such job. Thus the following actions are to improve the work condition ergonomicly in all operation in alumunium craft.

Colonoscopy is a standard method for screening polyps by highly trained physicians. Miss-detected polyps in colonoscopy are potential risk factor for colorectal cancer. In this study, we investigate an automatic polyp classification framework. We aim to compare two different approaches named hand-craft feature method and convolutional neural network (CNN) based deep learning method. Combined shape and color features are used for hand craft feature extraction and support vector machine (SVM) method is adopted for classification. For CNN approach, three convolution and pooling based deep learning framework is used for classification purpose. The proposed framework is evaluated using three public polyp databases. From the experimental results, we have shown that the CNN based deep learning framework shows better classification performance than the hand-craft feature based methods. It achieves over 90% of classification accuracy, sensitivity, specificity and precision.

Ayob, A F; Wan Nik, W B; Ray, T; Smith, W F

2012-01-01

Traditional approach on ship design involve the use of a method which takes a form that was earlier called the 'general design diagram' and is now known as the 'design spiral' – an iterative ship design process that allows for an increase in complexity and precision across the design cycle. Several advancements have been made towards the design spiral, however inefficient for handling complex simultaneous design changes, especially when later variable changes affect the ship's performance characteristics evaluated in earlier stages. Reviewed in this paper are several advancements in high speed planing craft design in preliminary design stage. An optimization framework for high speed planing craft is discussed which consist of surface information retrieval module, a suite of state-of-the-art optimization algorithms and standard naval architectural performance estimation tools. A summary of the implementation of the proposed hull surface information retrieval and several case studies are presented to demonstrate the capabilities of the framework.

Striving towards improved Friedel-Crafts acylation catalysts

1998-01-01

Full text: Lanthanum, ytterbium and scandium salts of trifluoromethanesulfonic acid have been shown to act as promising Lewis acid catalysts for the Friedel-Craft acylation reactions. In our study catalytic acylation of anisole by acetic anhydride in nitroethane was investigated. Yields were determined after extraction of para-methoxyacetophenone from the reaction mixture by G.L.C using the external standardisation method. Anhydrous lanthanoid tris-triflate salts [Ln(O 3 SCF 3 ) 3 , Ln La, Y, Nd, Eu and Yb] were initially investigated as catalysts. Ytterbium tris-triflate was found to be the most effective giving ∼90% of the acylation product. The hydrated lanthanide tris-nitrate salts [Ln(NO 3 ) 3 .nH 2 O, Ln = La, Nd, Eu and Yb] were also investigated using in situ dehydration with acetic anhydride. These were found to have low solubility in the reaction mixture and gave poor yields of para-methoxyacetophenone. The formation of side products was suggested by the low total recovery of anisole and para-methoxyacetophenone. The blocking of coordination sites of these catalysts by tetraglyme resulted in a 50% reduction in acylation activity compared with the simple salt. Addition of Li(O 3 SCF 3 ) to Ln(O 3 SCF 3 ) 3 catalysts (ratio of 4:1)had only a slight accelerating effect on the Friedel-Crafts acylation reaction and the yield was only marginally greater than that in the absence of the added salt. In contrast Li(ClO 4 ) dramatically decreased reaction times and improved the yield of para-methoxyace-tophenone, as recently reported

Deep Visual Attributes vs. Hand-Crafted Audio Features on Multidomain Speech Emotion Recognition

Directory of Open Access Journals (Sweden)

Michalis Papakostas

2017-06-01

Full Text Available Emotion recognition from speech may play a crucial role in many applications related to human–computer interaction or understanding the affective state of users in certain tasks, where other modalities such as video or physiological parameters are unavailable. In general, a human’s emotions may be recognized using several modalities such as analyzing facial expressions, speech, physiological parameters (e.g., electroencephalograms, electrocardiograms etc. However, measuring of these modalities may be difficult, obtrusive or require expensive hardware. In that context, speech may be the best alternative modality in many practical applications. In this work we present an approach that uses a Convolutional Neural Network (CNN functioning as a visual feature extractor and trained using raw speech information. In contrast to traditional machine learning approaches, CNNs are responsible for identifying the important features of the input thus, making the need of hand-crafted feature engineering optional in many tasks. In this paper no extra features are required other than the spectrogram representations and hand-crafted features were only extracted for validation purposes of our method. Moreover, it does not require any linguistic model and is not specific to any particular language. We compare the proposed approach using cross-language datasets and demonstrate that it is able to provide superior results vs. traditional ones that use hand-crafted features.

Three-Point Flexural Properties of Bonded Reinforcement Elements for Pleasure Craft Decks

Di Bella, G.; Galtieri, G.; Borsellino, C.

2018-02-01

The aim of this work was both to study the performances of pleasure craft reinforced components, bonded using a structural adhesive, and to compare them with those obtained using over-lamination as joining system, typically employed in the shipbuilding. With such aim, two different lots of components were prepared: in the first lot, the reinforcement structures were laminated directly on the investigated composite components and, in the second one; they were made separately in a mould and, then, bonded to the composite components. This last method allowed to evaluate the introduction of a product/process innovation in a field typically unwilling to innovation, still tied to craft, and non-standardized procedures. The results of bending tests, performed in order to evaluate the mechanical behaviour of the reinforced components, evidenced the goodness of this innovative design choice. Finally, a finite element analysis was performed. [Figure not available: see fulltext.

The Burden of Craft in Arthroscopic Rotator Cuff Repair: Where Have We Been and Where We Are Going.

Science.gov (United States)

Burkhart, Stephen S

2015-08-01

The rather turbulent history of arthroscopic rotator cuff repair went through stages of innovation, conflict, disruption, assimilation, and transformation that might be anticipated when a new and advanced technology (arthroscopic cuff repair) displaces an entrenched but outdated discipline (open cuff repair). The transition from open to arthroscopic rotator cuff repair has been a major paradigm shift that has greatly benefited patients. However, this technical evolution/revolution has also imposed a higher "burden of craft" on the practitioners of arthroscopic rotator cuff repair. Technological advancements in surgery demand that surgeons accept this burden of craft and master the advanced technology for the benefit of their patients. This article outlines the author's involvement in the development of arthroscopic rotator cuff repair, and it also explores the surgeon's obligation to accept the burden of craft that is imposed by this discipline.

Selling an Energy Efficiency Loan Portfolio in Oregon: Resale of the Craft3 loan portfolio to Self-Help Credit Union

Energy Technology Data Exchange (ETDEWEB)

Thompson, Peter; Borgeson, Merrian; Kramer, Chris; Zimring, Mark; Goldman, Charles

2014-05-30

Under the Clean Energy Works (CEW) program, Craft3 developed a loan product that widened access to financing for homeowners, offered long term funding, and collected repayments through the customer?s utility bill. The program?s success led Craft3 to pursue the sale of the loan portfolio to both mitigate its own risks and replenish funds for lending. This sale breaks new ground for energy efficiency finance and is notable as it was completed even with many novel program design elements. It replenished Craft3?s program capital and uncovered some valuable lessons that may facilitate future transactions. However, the lack of data history and the unproven nature of the loan portfolio meant that Craft3 had to limit the risk of losses to Self-Help, the purchaser of the portfolio. It remains to be seen whether this experience will pave the way for more sales of on-bill energy efficiency loan portfolios. This case study illustrates how certain program design decisions can sometimes both facilitate programmatic objectives and possibly present challenges for the sale of a portfolio of energy efficiency loans.

The poet begins the journey - that originates in the experience of death and destruction of a world shaken by the war, with a word that transcends the nonsense, and calls for “the country where forgiveness is / and are childhoods “a word that is built in search of human spaces and anticipates them. The adventure through the exercise of Solitude (1951, requirement beyond itself, a kind of internal and painful split: “I am separated from my heart,” releasing it, in turn, to the knowledge of the world and the gift that transfigures. The metamorphosis of the World (1951 takes place in the act of writing itself, for in him a knowledge of the essential reality is given, from which the party of pure celebrated say, “Oh breathing started / in the center of the loaf and snow “. Poetry as craft of transparency J.C. Renard develops in Un autre parole  (1981, prose poetry admirably clarifies its internal relations with theology and mysticism. The poet moves beyond “ailleurs” to a previous or future place of reconciliation and love letters between beings: “One happy pasture / leads above child / each wisdom to your name / and every love your body.”

Overview of craft brewing specificities and potentially associated microbiota.

Science.gov (United States)

Rodhouse, Lindsey; Carbonero, Franck

2017-09-14

The brewing process differs slightly in craft breweries as compared to industrial breweries, as there are fewer control points. This affects the microbiota of the final product. Beer contains several antimicrobial properties that protect it from pathogens, such as low pH, low oxygen and high carbon dioxide content, and the addition of hops. However, these hurdles have limited power controlling spoilage organisms. Contamination by these organisms can originate in the raw materials, persist in the environment, and be introduced by using flavoring ingredients later in the process. Spoilage is a prominent issue in brewing, and can cause quality degradation resulting in consumer rejection and product waste. For example, lactic acid bacteria are predominately associated with producing a ropy texture and haze, along with producing diacetyl which gives the beer butter flavor notes. Other microorganisms may not affect flavor or aroma, but can retard fermentation by consuming nutrients needed by fermentation yeast. Quality control in craft breweries today relies on culturing methods to detect specific spoilage organisms. Using media can be beneficial for detecting the most common beer spoilers, such as Lactobacillus and Pediococci. However, these methods are time consuming with long incubation periods. Molecular methods such as community profiling or high throughput sequencing are better used for identifying entire populations of beer. These methods allow for detection, differentiation, and identification of taxa.

“Not a Vacation, But a Hardening Process”: The Self-Empowerment Work of Therapeutic Craft in Nova Scotia

Directory of Open Access Journals (Sweden)

Erin Morton

2014-10-01

Full Text Available This article will examine the development of a state-sponsored therapeutic craft regime in Nova Scotia in the early to mid-twentieth century. Built on the notion that postwar residents needed "work therapy - not a vacation, but a hardening process" (Black n.d. a: 3 - therapeutic craft emerged in Nova Scotia through a complex combination of the individualization of work habits, the desire to construct an antimodern regional identity around handwork, and the notion that both infirm patients and the province as a whole could be healed from economic stagnation through craft. Key to the success of Nova Scotia's therapeutic craft regime was occupational therapist Mary E. Black's career as director of the provincial government's Handicrafts and Home Industries Division from 1943 to 1955. Black's healthcare training led her to seek out therapeutic possibilities in everyday work activities, not to mention a therapeutic solution to what she called "the atti-tude of most Nova Scotians"[:] defeatism" (Black 1949: 46. Her ability to turn seemingly disparate things - such as Scandinavian design, the ordered work of occupational rehabilitation, and a phenomenological focus on what she called “in-dividualistic existence” (Black n.d. b: 2 - into a unified therapeutic solution demonstrates that the contemporary rise of therapeutic culture under the increased individualism of the neoliberal era has an established historical root in the postwar period that remains important to understand.

Experimental studies of the rotor flow downwash on the Stability of multi-rotor crafts in descent

Science.gov (United States)

Veismann, Marcel; Dougherty, Christopher; Gharib, Morteza

2017-11-01

All rotorcrafts, including helicopters and multicopters, have the inherent problem of entering rotor downwash during vertical descent. As a result, the craft is subject to highly unsteady flow, called vortex ring state (VRS), which leads to a loss of lift and reduced stability. To date, experimental efforts to investigate this phenomenon have been largely limited to analysis of a single, fixed rotor mounted in a horizontal wind tunnel. Our current work aims to understand the interaction of multiple rotors in vertical descent by mounting a multi-rotor craft in a low speed, vertical wind tunnel. Experiments were performed with a fixed and rotationally free mounting; the latter allowing us to better capture the dynamics of a free flying drone. The effect of rotor separation on stability, generated thrust, and rotor wake interaction was characterized using force gauge data and PIV analysis for various descent velocities. The results obtained help us better understand fluid-craft interactions of drones in vertical descent and identify possible sources of instability. The presented material is based upon work supported by the Center for Autonomous Systems and Technologies (CAST) at the Graduate Aerospace Laboratories of the California Institute of Technology (GALCIT).

2017-11-01

High-throughput sequencing methods have become a routine analysis tool in environmental sciences as well as in public and private sector. These methods provide vast amount of data, which need to be analysed in several steps. Although the bioinformatics may be applied using several public tools, many analytical pipelines allow too few options for the optimal analysis for more complicated or customized designs. Here, we introduce PipeCraft, a flexible and handy bioinformatics pipeline with a user-friendly graphical interface that links several public tools for analysing amplicon sequencing data. Users are able to customize the pipeline by selecting the most suitable tools and options to process raw sequences from Illumina, Pacific Biosciences, Ion Torrent and Roche 454 sequencing platforms. We described the design and options of PipeCraft and evaluated its performance by analysing the data sets from three different sequencing platforms. We demonstrated that PipeCraft is able to process large data sets within 24 hr. The graphical user interface and the automated links between various bioinformatics tools enable easy customization of the workflow. All analytical steps and options are recorded in log files and are easily traceable. © 2017 John Wiley & Sons Ltd.

The Landing Craft Air Cushion is a high-speed, over-the-beach, fully amphibious landing craft capable of carrying a 60-75 ton payload. The LCAC fleet can serve to transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach. This transport system is an integral part of our military arsenal and, as such, its readiness is an important consideration for our national security. Further, the best way to expend financial resources that have been allocated to maintain this fleet is a critical Issue. There is a clear coupling between the measure of Fleet Readiness as defined by the customer for this project and the information that is provided by Sandia's ProOpta methodology. Further, there is a richness in the data that provides even more value to the analyst. This report provides an analytic framework for understanding the connection between Fleet Readiness and the output provided by Sandia's ProOpta software. Further, this report highlights valuable information that can also be made available using the ProOpta output and concepts from basic probability theory. Finally, enabling assumptions along with areas that warrant consideration for further study are identified.

The Aura of the Analogue in a Digital Age: Women’s Crafts, Creative Markets and Home-Based Labour After Etsy

Full Text Available This article examines the renewed popularity of the handmade by examining the current renaissance in the street credibility of previously disparaged women's craft practices, particularly those employing yarn (for example knitting, crochet, needlepoint and weaving and fabric (sewing, felting. The author historically locates current debates around craft production and creative work by drawing upon the British Arts and Crafts movement, with its own longstanding association with women's' labour in the home and desire to realise sustainable ethical labour practices. Notably, both the periods under discussion mark profound shifts in the economic organisation of society – then, the Industrial Revolution; now the de-industrialisation of much of the 'industrialised' world and the rise of the (digitised knowledge economy – and see a concurrent increase in the popularity of the handmade original as a desirable aesthetic object.

Full Text Available Aim. The aim of this study is to create and represent the tourist routes in the places of the traditional folk arts and crafts in the Republic of Dagestan.Research Methodology. In the first stage of the study, according to the register and public materials we identified and studied traditional places of folk arts and crafts; carried out monitoring of existing tourist routes and programs. Developed routes are included in the tourist route map.Findings and discussion. We developed five radial exit routes from the city of Makhachkala, characteristics of which are presented below. Folk arts and crafts of Dagestan are a unique part of the artistic culture and at the same time, it is a branch of industry with a high level of tourist attractiveness. Today, Dagestan is one of the few areas in the modern world where traditional folk art is naturally a part of a contemporary social life having the rights of the dominant cultural unity due to the peculiarities of its historical development. Archaeological studies show that due to the geographical position, in Dagestan, there has been an interaction of significant aspects of cultural phenomena relating to the ancient civilizations of the Mediterranean, Western, Central and Eastern Europe, on the one hand, and the development of cultures of different regions of Asia, on the other hand. Coupled with the traditions of the ancient population of the Caucasus, they formed complex and varied artistic conglomerate.Conclusion. The study revealed the basic centers of traditional arts and crafts of the Republic of Dagestan, hiving a high tourism potential. On this basis, we developed five tourist-excursion routes. These routes are included in the information booklet, which has a marketing and information value.

1985-01-01

Northern States Power Company is making a major effort to develop performance based training. It is finding the use of JTA data very helpful in the revision of its maintenance craft training programs. The technique being used involves a group of interns from the Training and Development Program of the University of Minnesota. These interns are largely graduate students, but with no nuclear and little mechanical/electrical experience. A Job Analysis for each discipline was used to: guide the following task analysis, determine program content, evaluate existing OJT check lists, and to define the four crafts used for mechanical maintenance. From the Job Analysis, a Training Task List was developed and correlated to training materials. The analysis of the tasks on the Training Task List is proceeding. Taxonomies of systems or subjects are compared to existing lesson plans. These taxonomies are useful when writing new lesson plans. The taxonomies are an excellent start for the development of enabling objectives. A Nine-Step Plan is being followed in the application of JTA data to the development and refinement of performance based training

Despite the progress in aging research that highlights the role of the nervous system in longevity, whether genes that control development and consequently structure of the nervous system affect lifespan is unclear. We demonstrated that a mutation inshuttle craft, a gene involved in the nervous system development, increased the lifespan of unmated females and decreased the lifespan of mated females, without affecting males. Precise reversions of the mutation lead to the restoration of the lifespan specific to control females. In mutant unmated females, increased lifespan was associated with elevated locomotion at older ages, indicating slowed aging. In mutant mated females, reproduction was decreased compared to controls, indicating a lack of tradeoff between this trait and lifespan. No differences in shuttle craft transcription were observed between whole bodies, ovaries, and brains of mutant and control females of different ages, either unmated or mated. The amount of shuttle craft transcript appeared to be substantially decreased in mutant embryos. Our results demonstrated that a gene that regulates development of the nervous system might also influence longevity, and thus expanded the spectrum of genes involved in lifespan control. We hypothesize that this "carry-over" effect might be the result of transcription regulation in embryos.

Detoxification with psychosocial counseling remains a standard opioid-use disorder treatment practice but is associated with poor outcomes. This study tested the efficacy of a newly developed psychosocial intervention, Community Reinforcement Approach and Family Training for Treatment Retention (CRAFT-T), relative to psychosocial treatment as usual (TAU), for improving treatment outcomes. A randomized, 14-week trial with follow-up visits at 6 and 9 months post-randomization conducted at two substance use disorder (SUD) treatment programs. Opioid-dependent adults (i.e., identified patient - IP) enrolled in a residential buprenorphine-detoxification program and their identified concerned significant other (CSO) was randomized to CRAFT-T (n=28 dyads) or TAU (n=24 dyads). CRAFT-T consisted of two sessions with the IP and CSO together and 10 with the CSO alone, over 14 weeks. TAU for the CSOs was primarily educational and referral to self-help. All IPs received treatment as usually provided by the SUD program in which they were enrolled. The primary outcome was time to first IP drop from treatment lasting 30 days or more. Opioid and other drug use were key secondary outcomes. CRAFT-T resulted in a moderate but non-significant effect on treatment retention (p=0.058, hazard ratio=0.57). When the CSO was parental family, CRAFT-T had a large and significant effect on treatment retention (pCRAFT-T had a significant positive effect on IP opioid and other drug use (pCRAFT-T is a promising treatment for opioid use disorder but replication is needed to confirm these results.

Multipurpose stabilization of the advanced marine surface crafts

Directory of Open Access Journals (Sweden)

Sevostyanov Ruslan A.

2016-01-01

Full Text Available Advanced marine surface crafts, such as SWATHs, catamarans or hovercrafts become more and more popular for a great range of various tasks. They usually operate at much higher speed than conventional ships. Moreover, in the open sea there are a lot of requirements and restrictions concerning the quality of such crafts’ dynamics, especially in case of the wind or waves. This paper considers application of the control law with a special multipurpose structure for autopilot design for amphibious air cushion vehicles. Such control law allows to decompose the autopilot task into simpler optimization subtasks. Efficiency of this approach is shown in the task of stabilizing yaw angle of the air cushion vehicle in the different weather conditions.

Full Text Available Uma das condições para que na sociedade sejam alicerçados valores de género misóginos consiste na existência de uma estrutura de produção cultural heterossexual compulsiva, dominante e universalista que estabeleça princípios de representação dos sexos claramente diferenciados, que tendam a favorecer mais o homem em detrimento da mulher. Partimos de um princípio de que a produção da cultura origina processos de reprodução, o que significa, em termos práticos, que a representação de signos, códigos, valores e comportamentos associados aos sexos é potencialmente materializada nas sociedades, por homens e por mulheres. Essa tem sido uma batalha levada a cabo por muitas mulheres a partir da segunda vaga do movimento feminista, nomeadamente pela ala mais radical, que tem procurado reivindicar novos paradigmas no que diz respeito às convenções culturais de género. O que propomos neste estudo é analisar algumas das campanhas levadas a cabo por Nikki Craft, uma feminista radical norte-americana que viria a organizar e/ou a protagonizar nos anos 1970 e 1980 vários protestos em espaços públicos de algumas cidades dos Estados Unidos.

Full Text Available This study investigates holistic craft processes in craft education with an instrument for data-collection and self-assessment. Teaching in a study context is based on co-teaching and a design process, highlighted by the Finnish Basic Education Core Curriculum 2014. The school architecture and web-based learning environment is combined. Division for textiles and technical work is no longer supported in this multimaterial learning environment. The aim of the study is to 1 make pupils’ holistic craft processes visible in everyday classroom practices with information collected by a mobile-application and 2 point out the curriculum topics that are covered during everyday classroom practices as defined by the teachers. The data is collected using an Experience Sampling Method with a gamified learning analytics instrument. Teachers’ classroom activities were used as the backbone for the thematic mapping of the craft curriculum. Preliminary measurements were carried out in a Finnish primary school in grades 5–6 (age 10–12, n = 125 during a four-week period in October-November 2016. The list of classroom activities was updated after the four weeks’ experiment and was tested in March-May 2017 with all the pupils of the pilot school (N = 353. The key findings were that a for pupils the self-assessment was easy as a technical process but there were several factors in the everyday classroom settings that made the process challenging and b it was relatively difficult for teachers to describe the classroom activities in terms of the new curriculum; however, after four weeks they could not only described the activities in more details but had also developed new activities that supported the ideas of the new curriculum better.Keywords: multi-material craft, learning environment, holistic craft process, experience sampling method

Design- and Craft thinking analysed as Embodied Cognition

Directory of Open Access Journals (Sweden)

Camilla Groth

2016-06-01

Full Text Available Through the concept of design thinking the act of designing is presented as an intellectual activity, and the act of planning the design is elevated over the making process. However, the importance of materiality and the embodied sense-making that occurs in this context should not be forgotten. In this study, embodied cognition in design and craft practices was investigated through three case studies. The study takes on an enhanced tactile perspective as a methodological platform; thus, the cases involve 1 deafblind makers in ceramics, 2 a practice-led self-study report on tactile experiences while working with clay and 3 a study on design students’ use of their tactile sense during material exploration. The results show that the act of thinking design involves the body as a knowledge provider.

Residual radioactive material guidelines for uranium were derived for the former Alba Craft Laboratory site in Oxford, Ohio. This site has been identified for remedial action under the Formerly Utilized Sites Remedial Action Program (FUSRAP) of the US Department of Energy (DOE). Single nuclide and total uranium guidelines were derived on the basis of the requirement that the 50-year committed effective dose equivalent to a hypothetical individual who lives or works in the immediate vicinity of the former Alba Craft Laboratory site should not exceed a dose of 30 mrem/yr following remedial action for the current use and likely future use scenarios or a dose of 100 mrem/yr for less likely future use scenarios (Yu et al. 1993). The DOE residual radioactive material guideline computer code, RESRAD, which implements the methodology described in the DOE manual for implementing residual radioactive material guidelines, was used in this evaluation

Teaching Quantum Mechanics with qCraft: Outreach and Video Games

Science.gov (United States)

Kubica, Aleksander; Chatwin-Davies, Aidan; Michalakis, Spyridon

Why is quantum mechanics considered a hard and inaccessible subject? Part of the difficulty is due to the nature of the subject itself. However, no small part of the difficulty is its pedagogy, which often relies on out-of-date historical motivation and experimental evidence that is disconnected from day-to-day experiences. In this first talk, we explore ways in which video games are well-suited to teaching quantum mechanics, in particular with regards to building intuition, as well as some of their limitations. We then illustrate these considerations through qCraft, an extension for Minecraft that incorporates aspects of quantum mechanics into the game.

We describe bottom-up fluorenol approach to create soluble covalent organic nano molecular architectures (ONAs) as potential multicomponent organic semiconductors (MOSs). BPyFBFFA as a typical model of ONAs and MOSs exhibits a persistent chair-shaped geometric structure that consists of hole-transporting tri phenylamine (TPA), high-efficiency ter fluorene, and high-mobility pyrenes. BPyFBFFA was synthesized via the intermediates PyFA and BPyFA with iterative Friedel-Crafts reactions and Suzuki cross-coupling reactions. BPyFBFFA behaves as an efficient blue light-emitter without the low-energy green emission band. Complex diaryl fluorenes (CDAFs) are promising candidates for nano scale covalent organic frameworks and MOSs. Friedel-Crafts protocols offer versatile toolboxes for molecular architects to frame chemistry and materials, nano science, and molecular nano technology as well as molecular manufactures

Anatomical models and wax Venuses: art masterpieces or scientific craft works?

Science.gov (United States)

Ballestriero, R

2010-02-01

The art of wax modelling has an ancient origin but rose to prominence in 14th century Italy with the cult of votive artefacts. With the advent of Neoclassicism this art, now deemed repulsive, continued to survive in a scientific environment, where it flourished in the study of normal and pathological anatomy, obstetrics, zoology and botany. The achievement of having originated the creation of anatomical models in coloured wax must be ascribed to a joint effort undertaken by the Sicilian wax modeller Gaetano Giulio Zumbo and the French surgeon Guillaume Desnoues in the late 17th century. Interest in anatomical wax models spread throughout Europe during the 18th century, first in Bologna with Ercole Lelli, Giovanni Manzolini and Anna Morandi, and then in Florence with Felice Fontana and Clemente Susini. In England, the art of anatomical ceroplastics was brought to London from Florence by the sculptor Joseph Towne. Throughout the centuries many anatomical artists preferred this material due to the remarkable mimetic likeness obtained, far surpassing any other material. Independent of the material used, whether wood, wax or clay, anatomical models were always considered merely craft works confined to hospitals or faculties of medicine and have survived to this day only because of their scientific interest. Italian and English waxes are stylistically different but the remarkable results obtained by Susini and Towne, and the fact that some contemporary artists are again representing anatomical wax bodies in their works, makes the border that formerly separated art and craft indistinguishable.

Wetland craft plants in KwaZulu-Natal: an ecological review of har­vesting impacts and implications for sustainable utilization

Directory of Open Access Journals (Sweden)

C. H. Traynor

2010-07-01

Full Text Available In South Africa, wetland plants have been used for centuries and they continue to be harvested for subsistence and commercial purposes. Fibres for crafts are collected by cutting the aboveground parts. KwaZulu-Natal is one of the major basket-producing regions in southern Africa and at least twenty-two species of wetland plants are harvested for crafts. A literature review of the harvested species revealed that the impacts of cutting have only been extensively investigated for Phragmites australis (Cav. Steud. and Juncus kraussii Hochst. The review suggested that, where plants display strong seasonal aboveground productivity patterns, cutting should take place after shoot senescence and before new shoot emergence to minimize damage to plants. Cutting in the short term could increase the density of green stems. However, in the long term in  Phragmites australis, it may deplete the rhizome reserves and reduce the density of useable (longer and thicker culms.The opportunity for sustainable harvests was investigated by considering the geographic distribution, whether species are habitat specific or not, and local population sizes of the craft plants. Juncus kraussii is of the greatest conservation concern.Ecologically sustainable wetland plant harv esting could contribute to the wise use of wetlands, an approach promoted nationally and internationally.

A new strategy has been developed for the encapsulation of the phosphotungstic heteropoly acid (H{sub 3}PW{sub 12}O{sub 40} denoted as PTA) into zeolite imidazolate framework (ZIF-67) cage and the PTA@ZIF-67(ec) catalysts with different PTA content were prepared. The structure of the catalysts was characterized by XRD, BET, SEM, FT-IR, ICP-AES and TG. The catalytic activity and recovery properties of the catalysts for the Friedel-Crafts acylation of anisole with benzoyl chloride were evaluated. The results showed that 14.6–31.7 wt% PTA were encapsulated in the ZIF-67 cage. The PTA@ZIF-67(ec) catalysts had good catalytic activity for Friedel-Crafts acylation. The conversion of anisole can reach ~100% and the selectivity of the production can reach ~94% over 26.5 wt% PTA@ZIF-67(ec) catalyst under the reaction condition of 120 °C and 6 h. After reaction, the catalyst can be easily separated from the reaction mixture by the centrifugation. The recovered catalyst can be reused five times and the selectivity can be kept over 90%. - Graphical abstract: The PTA@ZIF-67 catalysts with different PTA content were prepared by encapsulating the PTA into ZIF-67 cage and the as-synthesized catalysts exhibited good catalytic activity for the Friedel–Craft acylation of anisole with benzoyl chloride.

Beer is one of the world's most ancient and widely consumed fermented alcoholic beverages produced with water, malted cereal grains (generally barley and wheat), hops, and yeast. Beer is considered an unfavorable substrate of growth for many microorganisms, however, there are a limited number of bacteria and yeasts, which are capable of growth and may spoil beer especially if it is not pasteurized or sterile-filtered as craft beer. The aim of this research study was to track beer spoilage lactic acid bacteria (LAB) inside a brewery and during the craft beer production process. To that end, indoor air and work surface samples, collected in the brewery under study, together with commercial active dry yeasts, exhausted yeasts, yeast pellet (obtained after mature beer centrifugation), and spoiled beers were analyzed through culture-dependent methods and PCR-DGGE in order to identify the contaminant LAB species and the source of contamination. Lactobacillus brevis was detected in a spoiled beer and in a commercial active dry yeast. Other LAB species and bacteria ascribed to Staphylococcus sp., Enterobaceriaceae, and Acetobacter sp. were found in the brewery. In conclusion, the PCR-DGGE technique coupled with the culture-dependent method was found to be a useful tool for identifying the beer spoilage bacteria and the source of contamination. The analyses carried out on raw materials, by-products, final products, and the brewery were useful for implementing a sanitization plan to be adopted in the production plant. © 2015 Institute of Food Technologists®

Las modificaciones se han realizado con cauchos, policloruro de vinilo, anhídrido ftálico, anhídrido maléico, 1,2-propanodiol, hexametilendiisocianato y toluen-2,4-diisocianato.

CRAFT (complete reduction to amplitude frequency table)--robust and time-efficient Bayesian approach for quantitative mixture analysis by NMR.

Science.gov (United States)

Krishnamurthy, Krish

2013-12-01

The intrinsic quantitative nature of NMR is increasingly exploited in areas ranging from complex mixture analysis (as in metabolomics and reaction monitoring) to quality assurance/control. Complex NMR spectra are more common than not, and therefore, extraction of quantitative information generally involves significant prior knowledge and/or operator interaction to characterize resonances of interest. Moreover, in most NMR-based metabolomic experiments, the signals from metabolites are normally present as a mixture of overlapping resonances, making quantification difficult. Time-domain Bayesian approaches have been reported to be better than conventional frequency-domain analysis at identifying subtle changes in signal amplitude. We discuss an approach that exploits Bayesian analysis to achieve a complete reduction to amplitude frequency table (CRAFT) in an automated and time-efficient fashion - thus converting the time-domain FID to a frequency-amplitude table. CRAFT uses a two-step approach to FID analysis. First, the FID is digitally filtered and downsampled to several sub FIDs, and secondly, these sub FIDs are then modeled as sums of decaying sinusoids using the Bayesian approach. CRAFT tables can be used for further data mining of quantitative information using fingerprint chemical shifts of compounds of interest and/or statistical analysis of modulation of chemical quantity in a biological study (metabolomics) or process study (reaction monitoring) or quality assurance/control. The basic principles behind this approach as well as results to evaluate the effectiveness of this approach in mixture analysis are presented. Copyright © 2013 John Wiley & Sons, Ltd.

A Probabilistic and Observation Based Methodology to Estimate Small Craft Harbor Vulnerability to Tsunami Events

Science.gov (United States)

Keen, A. S.; Lynett, P. J.; Ayca, A.

2016-12-01

Because of the damage resulting from the 2010 Chile and 2011 Japanese tele-tsunamis, the tsunami risk to the small craft marinas in California has become an important concern. The talk will outline an assessment tool which can be used to assess the tsunami hazard to small craft harbors. The methodology is based on the demand and structural capacity of the floating dock system, composed of floating docks/fingers and moored vessels. The structural demand is determined using a Monte Carlo methodology. Monte Carlo methodology is a probabilistic computational tool where the governing might be well known, but the independent variables of the input (demand) as well as the resisting structural components (capacity) may not be completely known. The Monte Carlo approach uses a distribution of each variable, and then uses that random variable within the described parameters, to generate a single computation. The process then repeats hundreds or thousands of times. The numerical model "Method of Splitting Tsunamis" (MOST) has been used to determine the inputs for the small craft harbors within California. Hydrodynamic model results of current speed, direction and surface elevation were incorporated via the drag equations to provide the bases of the demand term. To determine the capacities, an inspection program was developed to identify common features of structural components. A total of six harbors have been inspected ranging from Crescent City in Northern California to Oceanside Harbor in Southern California. Results from the inspection program were used to develop component capacity tables which incorporated the basic specifications of each component (e.g. bolt size and configuration) and a reduction factor (which accounts for the component reduction in capacity with age) to estimate in situ capacities. Like the demand term, these capacities are added probabilistically into the model. To date the model has been applied to Santa Cruz Harbor as well as Noyo River. Once

Sanders, Alison P; Miller, Sloane K; Nguyen, Viet; Kotch, Jonathan B; Fry, Rebecca C

2014-02-04

In Vietnam, environmental pollution caused by small-scale domestic smelting of automobile batteries into lead ingot is a growing concern. The village of Nghia Lo is a smelting craft village located roughly 25 km southeast of Hanoi in the Red River Delta. Despite the concern of toxic metal exposure in the village, biomonitoring among susceptible populations, such as children, has not been previously conducted. The aim of this study was to determine the body burden of toxic metals in children residing in a smelting craft village. Twenty children from Nghia Lo, Vietnam, ages 18 months to four years were selected for capillary whole blood and toenail biomonitoring. Whole blood lead levels (BLLs) were measured using a portable lead analyzer, and toenail levels of arsenic, cadmium, chromium, lead, manganese, and mercury were analyzed with inductively coupled plasma-mass spectrometry. The findings show that all of the 20 children had detectable BLLs, and every child had levels that exceeded the Centers for Disease Control and Prevention guideline level of 5 μg/dL. Eighty percent of tested subjects had BLLs higher than 10 μg/dL. Five children (25%) had BLLs greater than 45 μg/dL, the level of recommended medical intervention. In addition to blood lead, all of the children had detectable levels of arsenic, cadmium, chromium, lead, manganese, and mercury in toenail samples. Notably, average toenail lead, manganese, and mercury levels were 157 μg/g, 7.41 μg/g, and 2.63 μg/g respectively, well above levels previously reported in children. Significant Spearman's rank correlations showed that there were relationships between blood and toenail lead levels (r = 0.65, p craft villages in Vietnam are co-exposed to toxic metals. There is an urgent need for mitigation to control metal exposure related to domestic smelting.

Using Soft Sculpture Microfossils and Other Crafted Models to Teach Geoscience

Science.gov (United States)

Spinak, N. R.

2017-12-01

For the past 5 years, the International Ocean Discovery Program (IODP) has been using the author's sewn models of microfossils to help learners understand the shapes and design of these tiny fossils. These tactile objects make the study of ancient underwater life more tangible. Multiple studies have shown that interactive models can help many learners understand science. The Montessori and Waldorf education programs are based in large part on earlier insights into meeting these needs. The act of drawing has been an essential part of medical education. The STEAM (Science, Technology, Engineering, Arts and Math) movement has advocated for STEM supporters to recognize the inseparability of science and art. This presentation describes how the author's knitted or sewn models of microfossils incorporate art and design into geoscience education. The geoscience research and art processes used in developing and creating these educational soft sculptures will be described. In multiple entry points to science study, specific reciprocal benefits to boundary crossing among the arts and sciences for those who have primary talents in a particular area of study will be discussed. Geoscience education can benefit from using art and craft items such as models. Many websites now offer soft sculptures for biology study such as organs and germs (e.g. (https://www.giantmicrobes.com/us/main/nasty-germs). The Wortheim project involving community and crochet is another approach (http://crochetcoralreef.org/). These tactile artifacts give learners an entry-level experience with biology. Three dimensional models are multisensory. The enlarged manipulative microfossil models invite learners to make comparisons and gain insights when microscopes are not available or appropriate for the audience. Adding the physical involvement of creating a microfossil yourself increases the multi-sensory experience even further. Learning craft skills extends the cross-cutting concepts of the NGSS to a mutual

Adrijana Poljanšek

2017-09-01

Full Text Available The new collective trademark Izdelek slovenske obrti (hereinafter: PSC; English: Product of Slovenian Craft was launched on the market in 2014. The initiative for the trademark was provided by the Textile Section at the Chamber of Craft and Small Business of Slovenia (hereinafter: the OZS, which also registered the trademark. Members of the OZS have the right to obtain and use the trademark, and to use it to promote their products or services. After two years, only a small number of section members use the trademark. Because the section would like to see an increased number of members use the trademark, research regarding the latter was carried out. The results are presented in this article. The descriptive course of development and registration of the collective trademark PSC is presented in the first part of our research. In the second part, questionnaires were drafted for collective trademark PSC users, potential users and consumers. The results obtained using three questionnaires were analysed using a SWOT analysis. Based on the results, it was determined that the trademark has not yet been properly positioned on the Slovenian market. Advantages include the familiarity of Textile Section members with the trademark, and their eagerness to use it. One disadvantage is the trademark’s current lack of recognition among consumers. For this reason, section members who are also potential users of the trademark do not give it priority and therefore do not opt to use it. The following will impact the trademark’s recognition among consumers: innovative marketing campaigns, the inclusion of the media and social networks, the improved recognition and visibility of the logotype, and an effective and pervasive slogan, as was determined in our research.

Design Method for Contra-Rotating Propellers for High-Speed Crafts: Revising the Original Lerbs Theory in a Modern Perspective

Directory of Open Access Journals (Sweden)

Stefano Brizzolara

2012-01-01

Full Text Available The main theoretical and numerical aspects of a design method for optimum contrar-rotating (CR propellers for fast marine crafts are presented. We propose a reformulated version of a well-known design theory for contra-rotating propellers, by taking advantage of a new fully numerical algorithm for the calculation of the mutually induced velocities and introducing new features such as numerical lifting surface corrections, use of an integrated modern cavitation/strength criteria, a modified method to consider different numbers of blades among the two propellers, and to allow for an unloading function in the search for the optimal circulation distribution. The paper first introduces the main theoretical principles of the new methods and then discusses the influence of the main design parameters on an emblematic example of application in the case of counter rotating propellers for a pod propulsor designed for fast planing crafts (35 knots and above.

[Simplified models of analysis of the sources of risk and biomechanical overload in craft industries: application experience in wooden barrel making].

Pressiani, Sofia

2011-01-01

Barrel making is an ancient art evidence of which is found in paintings from the Egyptian era in the Mediterranean civilizations, and since it was an ideal shipping container its use spread quickly and on a wide scale. The study was conducted in a small high quality craft industry, applying the method which is the topic of this volume, i.e., risk pre-mapping by which it is possible to identify the presence or absence of occupational risk and any need for further evaluation. The study showed the presence of health risks for workers, which were mainly physical (noise, vibrations produced by machinery and equipment typical of the craft, and risks from hardwood dust, in addition to the traditional risks of biomechanical overload of the upper limbs. Today, the barrel maker is a professional craft of excellence and quality, dedicated to the creation of large barrels and vats, using woods of different essences depending on the organoleptic qualities that it is desired should influence the final flavour of the wine: the manual art and the equipment are ancient but the technology used to achieve the final product is necessarily advanced. So far issues of safety and health risks related to this type of industry have received little attention and the risks poorly evaluated, with the possibility that occupational diseases may occur among the operators, particularly of the skeletal-muscular type.

Low-cost silicon wafer dicing using a craft cutter

KAUST Repository

Fan, Yiqiang

2014-05-20

This paper reports a low-cost silicon wafer dicing technique using a commercial craft cutter. The 4-inch silicon wafers were scribed using a crafter cutter with a mounted diamond blade. The pre-programmed automated process can reach a minimum die feature of 3 mm by 3 mm. We performed this scribing process on the top polished surface of a silicon wafer; we also created a scribing method for the back-unpolished surface in order to protect the structures on the wafer during scribing. Compared with other wafer dicing methods, our proposed dicing technique is extremely low cost (lower than $1,000), and suitable for silicon wafer dicing in microelectromechanical or microfluidic fields, which usually have a relatively large die dimension. The proposed dicing technique is also usable for dicing multiple project wafers, a process where dies of different dimensions are diced on the same wafer.

Kamboj, S.; Nimmagadda, M.; Yu, C.

1996-04-01

Potential maximum radiation dose rates were calculated for the former Alba Craft Laboratory site in Oxford, Ohio, which was involved in machining of uranium metal in the 1950s for the U.S. atomic energy program. The site is not currently being used. The residual radioactive material guidelines (RESRAD) computer code, which implements the methodology described in the US Department of Energy's (DOE's) manual for establishing residual radioactive material guidelines, was sued in this evaluation. Three potential land use scenarios were considered for the former Alba Craft site; the scenarios vary with regard to the type of site use, time spent at the site by the exposed individual, and sources of food consumed. Scenario A (a possible land use scenario) assumed industrial use of the site; Scenario B (a likely future land use scenario) assumed residential use of the site; and Scenario C (a possible but unlikely land use scenario) assumed the presence of a resident farmer. For scenario A, it was assumed that any water used for domestic or industrial activities would be from uncontaminated off-site municipal sources. The water used for drinking, household purposes, and irrigation was assumed to be from uncontaminated municipal sources in Scenario B; groundwater drawn from a well located at the downgradient edge of the contaminated zone would be the only source of water for drinking, irrigation, and raising livestock in Scenario C. The results of the evaluation indicated that the DOE dose limit of 100 mrem/yr would not be exceeded for any of the scenarios analyzed. The potential maximum dose rates for Scenarios A, B, and C are 0.64, 2.0, and 11 mrem/yr, respectively

Milk and dairy products are sustainable to the development of numerous microorganisms, especially pathogens. Therewith, it is necessary to achieve a high level of hygiene in dairy plants, in order to get safe and high quality products. Based on that, modern food production implies application of different air treatments. Microbiological status of air and working surfaces in the cheese and kajmak craft production, before and after air treatment by bipolar ionization, was investigated. It is concluded that bipolar ionization may be considered as an efficient method for improving of microbiological status of air, as well as surfaces that are in contact with the air

Noble gas control room accident filtration system for severe accident conditions N-CRAFT. System design

International Nuclear Information System (INIS)

Hill, Axel

2014-01-01

Severe accidents might cause the release of airborne radioactive substances to the environment of the NPP. This can either be due to leakages of the containment or due to a filtered containment venting in order to ensure the overall integrity of the containment. During the containment venting process aerosols and iodine can be retained by the FCVS which prevents long term ground contamination. Noble gases are not retainable by the FCVS. From this it follows that a large amount of radioactive noble gases (e.g. xenon, krypton) might be present in the nearby environment of the plant dominating the activity release, depending on the venting procedure and the weather conditions. Accident management measures are necessary in case of severe accidents and the prolonged stay of staff inside the main control room (MCR) or emergency response center (ERC) is essential. Therefore, the in leakage and contamination of the MRC and ERC with airborne activity has to be prevented. The radiation exposure of the crises team needs to be minimized. The entrance of noble gases cannot be sufficiently prevented by the conventional air filtration systems such as HEPA filters and iodine absorbers. With the objective to prevent an unacceptable contamination of the MCR/ERC atmosphere by noble gases AREVA GmbH has developed a noble gas retention system. The noble gas control room accident filtration system CRAFT is designed for this case and provides supply of fresh air to the MCR/ERC without time limitation. The retention process of the system is based on the dynamic adsorption of noble gases on activated carbon. The system consists of delay lines (carbon columns) which are operated by a continuous and simultaneous adsorption and desorption process. These cycles ensure a periodic load and flushing of the delay lines retaining the noble gases from entering the MCR. CRAFT allows a minimization of the dose rate inside MCR/ERC and ensures a low radiation exposure to the staff on shift maintaining

Crafting Sustainable Development Solutions: Frugal Innovations of Grassroots Entrepreneurs

Directory of Open Access Journals (Sweden)

Mario Pansera

2016-01-01

Full Text Available A shift in the entrepreneurial landscape is taking place brought about by grassroots innovators with little formal education and technological knowhow, living and working in penurious environments. This research represents an emerging third wave of literature on Bottom of the Pyramid innovation, where products are offered for and by the underserved. Using primary and secondary data derived from four cases of grassroots entrepreneurs in the Indian Subcontinent, the study explores the phenomenon where resource scarce entrepreneurs craft solutions that are environmental friendly, with low overall ownership costs, and use locally available material. We argue that the grassroots phenomenon can be fruitfully exploited to achieve the new Sustainable Development Goals proposed by the UN as a post-2015 strategy for the future of global governance. These innovations might have a tremendous impact not only in terms of serving unmet and ignored consumer needs, but also longer term impacts through enhanced productivity, sustainability, poverty reduction and inclusion promotion.

Application of a Spectral Wave Model to Assess Breakwater Configurations at a Small Craft Harbour on Lake Ontario

Directory of Open Access Journals (Sweden)

Amelia H. Cooper

2016-08-01

Full Text Available A surface wave model using three nested grids is applied to the eastern end of Lake Ontario to investigate wave propagation from an open lake environment to a small craft harbour protected by a breakwater. The Simulating WAves Nearshore (SWAN spectral wave model, coupled with the Delft3D hydrodynamic model, is applied to simulate a series of storms in November, 2013. The model results are compared to observations from two pressure sensors, and used to quantify wave properties around existing and future breakwaters to evaluate the bulk changes to the harbour configuration. Overall, the results indicate that the rubblemound breakwater reduces wave heights in the existing harbour by 63% compared to no breakwater, and that the addition of a surface breakwater extension could reduce wave heights by an additional 54%. Wave height attenuation was found to be highly dependent on the incident wave direction relative to breakwater orientation. The spectral wave model is useful for simulating wave transformation for broad directional spectra in wind-sea conditions over large scales to semi-protected areas such as small craft harbours.

Between October 1952 and February 1957, National Lead of Ohio (NLO), a primary contractor for the Atomic Energy Commission (AEC), subcontracted certain uranium machining operations to Alba Craft Laboratory, Incorporated, located at 10-14 West Rose Avenue, Oxford, Ohio. In 1992, personnel from Oak Ridge National Laboratory (ORNL) confirmed the presence of residual radioactive materials from the AEC-related operations in and around the facility in amounts exceeding the applicable Department of Energy (DOE) guidelines. Although the amount of uranium found on the property posed little health hazard if left undisturbed, the levels were sufficient to require remediation to bring radiological conditions into compliance with current guidelines, thus ensuring that the public and the environment are protected. A team from ORNL conducted a radiological verification survey of the former Alba Craft Laboratory property between December 1994 and February 1995. The survey was conducted at the request of DOE and included directly measured radiation levels, the collection and analysis of soil samples to determine concentrations of uranium and certain other radionuclides, and comparison of these data to the guidelines. This document reports the findings of this survey. The results of the independent verification survey of the former Alba Craft Laboratory property demonstrate that all contaminated areas have been remediated to radionuclide concentrations and activity levels below the applicable guideline limits set by DOE

The instability occurring of the OTSG (Once-Through Steam Generator) in naval craft nuclear power plants is presented by the multivariable frequency domain theory. As concerning coupling interactions of the OTSG tubing, it is more accurate for analyzing the instability of OTSG compared to the common single variable method. A mathematical model for the system is derived from the fundamental equations by using the perturbation, Laplace-transform and the nodalization techniques. The stable boundary and parameters which influence the stability of the system are evaluated through computer simulation.

Full Text Available This article introduces a real-time vision-based method for guided autonomous landing of a rotor-craft unmanned aerial vehicle. In the process of designing the pattern of landing target, we have fully considered how to make this easier for simplified identification and calibration. A linear algorithm was also applied using a three-dimensional structure estimation in real time. In addition, multiple-view vision technology is utilized to calibrate intrinsic parameters of camera online, so calibration prior to flight is unnecessary and the focus of camera can be changed freely in flight, thus upgrading the flexibility and practicality of the method.

A Friedel-Crafts benzylation of arenes with benzyl fluorides has been developed. The reaction produces 1,1-diaryl alkanes in good yield under mild conditions without the need for a transition metal or a strong Lewis acid. A mechanism involving activation of the C-F bond through hydrogen bonding is proposed. This mode of activation enables the selective reaction of benzylic C-F bonds in the presence of other benzylic leaving groups. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

High-performance marine craft crews are susceptible to various adverse health conditions caused by multiple interactive factors. However, there are limited epidemiological data available for assessment of working conditions at sea. Although questionnaire surveys are widely used for identifying exposures, outcomes and associated risks with high accuracy levels, until now, no validated epidemiological tool exists for surveying occupational health and performance in these populations. To develop and validate a web-based questionnaire for epidemiological assessment of occupational and individual risk exposure pertinent to the musculoskeletal health conditions and performance in high-performance marine craft populations. A questionnaire for investigating the association between work-related exposure, performance and health was initially developed by a consensus panel under four subdomains, viz. demography, lifestyle, work exposure and health and systematically validated by expert raters for content relevance and simplicity in three consecutive stages, each iteratively followed by a consensus panel revision. The item content validity index (I-CVI) was determined as the proportion of experts giving a rating of 3 or 4. The scale content validity index (S-CVI/Ave) was computed by averaging the I-CVIs for the assessment of the questionnaire as a tool. Finally, the questionnaire was pilot tested. The S-CVI/Ave increased from 0.89 to 0.96 for relevance and from 0.76 to 0.94 for simplicity, resulting in 36 items in the final questionnaire. The pilot test confirmed the feasibility of the questionnaire. The present study shows that the web-based questionnaire fulfils previously published validity acceptance criteria and is therefore considered valid and feasible for the empirical surveying of epidemiological aspects among high-performance marine craft crews and similar populations.

2009-04-01

Full Text Available Methanetrisulfonic acid had been prepared for the first time over 140 years ago, but it was used only scarcely in chemical transformations. In the course of our activities dealing with key-steps of industrial syntheses of vitamins, e.g. economically important vitamin E (acetate, we found that methanetrisulfonic acid is an extremely effective catalyst in a variety of reactions. Examples of its applications are Wagner-Meerwein rearrangements, Friedel-Crafts alkylations and ring closures, as well as acylation reactions. Use of this catalyst in truly catalytic amounts (0.04-1.0 mol% resulted in highly selective transformations and yields over 95%. (Remark by the authors: We are describing only one example each for the various types of reactions. Therefore, it would be more appropriate to write (here and in the Introduction and in the Conclusion sections: “Wagner-Meerwein rearrangement, Friedel-Crafts alkylation and ring closure, as well as acylation reactions”

Coreference resolution is the task of finding strings in text that have the same referent as other strings. Failures of coreference resolution are a common cause of false negatives in information extraction from the scientific literature. In order to better understand the nature of the phenomenon of coreference in biomedical publications and to increase performance on the task, we annotated the Colorado Richly Annotated Full Text (CRAFT) corpus with coreference relations. The corpus was manually annotated with coreference relations, including identity and appositives for all coreferring base noun phrases. The OntoNotes annotation guidelines, with minor adaptations, were used. Interannotator agreement ranges from 0.480 (entity-based CEAF) to 0.858 (Class-B3), depending on the metric that is used to assess it. The resulting corpus adds nearly 30,000 annotations to the previous release of the CRAFT corpus. Differences from related projects include a much broader definition of markables, connection to extensive annotation of several domain-relevant semantic classes, and connection to complete syntactic annotation. Tool performance was benchmarked on the data. A publicly available out-of-the-box, general-domain coreference resolution system achieved an F-measure of 0.14 (B3), while a simple domain-adapted rule-based system achieved an F-measure of 0.42. An ensemble of the two reached F of 0.46. Following the IDENTITY chains in the data would add 106,263 additional named entities in the full 97-paper corpus, for an increase of 76% percent in the semantic classes of the eight ontologies that have been annotated in earlier versions of the CRAFT corpus. The project produced a large data set for further investigation of coreference and coreference resolution in the scientific literature. The work raised issues in the phenomenon of reference in this domain and genre, and the paper proposes that many mentions that would be considered generic in the general domain are not

2016-12-22

Los Alamos National Laboratory (LANL) and the federal government require those working with or near electrical equipment to be trained on electrical hazards and how to avoid them. Although you might not be trained to work on electrical systems, your understanding of electricity, how it can hurt you, and what precautions to take when working near electricity could save you or others from injury or death. This course, Electrical Safety Program: Nonelectrical Crafts at LANL (12175), provides knowledge of basic electrical concepts, such as current, voltage, and resistance, and their relationship to each other. You will learn how to apply these concepts to safe work practices while learning about the dangers of electricity—and associated hazards—that you may encounter on the job. The course also discusses what you can do to prevent electrical accidents and what you should do in the event of an electrical emergency. The LANL Electrical Safety Program is defined by LANL Procedure (P) 101-13. An electrical safety officer (ESO) is well versed in this document and should be consulted regarding electrical questions. Appointed by the responsible line manager (RLM), ESOs can tell you if a piece of equipment or an operation is safe or how to make it safe.

Simulating high frequency water quality monitoring data using a catchment runoff attenuation flux tool (CRAFT).

Adams, Russell; Quinn, Paul F; Perks, Matthew; Barber, Nicholas J; Jonczyk, Jennine; Owen, Gareth J

2016-12-01

High resolution water quality data has recently become widely available from numerous catchment based monitoring schemes. However, the models that can reproduce time series of concentrations or fluxes have not kept pace with the advances in monitoring data. Model performance at predicting phosphorus (P) and sediment concentrations has frequently been poor with models not fit for purpose except for predicting annual losses. Here, the data from the Eden Demonstration Test Catchments (DTC) project have been used to calibrate the Catchment Runoff Attenuation Flux Tool (CRAFT), a new, parsimonious model developed with the aim of modelling both the generation and attenuation of nutrients and sediments in small to medium sized catchments. The CRAFT has the ability to run on an hourly timestep and can calculate the mass of sediments and nutrients transported by three flow pathways representing rapid surface runoff, fast subsurface drainage and slow groundwater flow (baseflow). The attenuation feature of the model is introduced here; this enables surface runoff and contaminants transported via this pathway to be delayed in reaching the catchment outlet. It was used to investigate some hypotheses of nutrient and sediment transport in the Newby Beck Catchment (NBC) Model performance was assessed using a suite of metrics including visual best fit and the Nash-Sutcliffe efficiency. It was found that this approach for water quality models may be the best assessment method as opposed to using a single metric. Furthermore, it was found that, when the aim of the simulations was to reproduce the time series of total P (TP) or total reactive P (TRP) to get the best visual fit, that attenuation was required. The model will be used in the future to explore the impacts on water quality of different mitigation options in the catchment; these will include attenuation of surface runoff.

Effects of stern-foil submerged elevation on the lift and drag of a hydrofoil craft

Science.gov (United States)

Suastika, K.; Apriansyah

2018-03-01

Effects of the stern-foil submerged elevation on the lift and drag of a hydrofoil craft are studied by using computational fluid dynamics (CFD) and by considering three alternative stern-foil submerged elevations. The submerged elevation of the front foil is kept constant in all the alternatives. From among the alternatives, the deepest stern-foil placement results in the highest stern-foil lift with the highest foil’s lift-to-drag ratio. However, considering the lift-to-drag ratio of the whole foil-strut-hull system, the shallowest stern-foil placement results in the highest lift-to-drag ratio. The struts and the foil’s submerged elevation significantly affects the drag of the whole foil-strut-hull system.

2017-09-01

In today's market, every product seems to be marked by the label of "experience". It is expected that successful products give the consumer "extraordinary experiences". The research in consumption experience is growing, but much work still needs to be done to understand the food and beverage experience. A qualitative study was conducted using contextual focus groups to explore the building blocks of consumers' drinking experience of industrial and craft beers. The results show that drinking experience is shaped by our cognitive, sensory or affective systems, especially during the core consumption experience. Elements such as attitudes, consumption habits, and individual versus social consumption, shopping experience and product benefits are also responsible for shaping the experience, but are more relevant during the pre-consumption or post-consumption experience. Gender differences occur more frequently in the affective experience, as women search more for relaxation while men for excitement and stimulation while drinking beer. When comparing industrial users versus craft, in the latter the cognitive and shopping experiences are more relevant. Overall, the results showed that the drinking experience of beers can be studied as a function of the salient human system used during product interaction, and this systems act as the building blocks of the drinking experience of beer. This information can be applied in consumer research studies to further study the experiential differences across products and consumers. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available The interaction of electrons with a periodic potential of atoms in crystalline solids gives rise to band structure. The band structure of existing materials can be measured by photoemission spectroscopy and accurately understood in terms of the tight-binding model, however not many experimental approaches exist that allow to tailor artificial crystal lattices using a bottom-up approach. The ability to engineer and study atomically crafted designer materials by scanning tunnelling microscopy and spectroscopy (STM/STS helps to understand the emergence of material properties. Here, we use atom manipulation of individual vacancies in a chlorine monolayer on Cu(100 to construct one- and two-dimensional structures of various densities and sizes. Local STS measurements reveal the emergence of quasiparticle bands, evidenced by standing Bloch waves, with tuneable dispersion. The experimental data are understood in terms of a tight-binding model combined with an additional broadening term that allows an estimation of the coupling to the underlying substrate.

2005-09-28

The first synthesis of taiwaniaquinol B, a 6-nor-5(6-->7)abeoabietane-type diterpenoid exhibiting the uncommon fused 6-5-6 tricyclic carbon skeleton, was accomplished in 15 steps. A Lewis acid-promoted tandem intramolecular Friedel-Crafts/carbonyl alpha-tert-alkylation reaction was exploited as the core strategy for the synthesis of the sterically congested 1-indanone-containing tricyclic structure. This multiple carbon-carbon bond forming reaction exploits the unique reactivity of Meldrum's acid. The facile precursor synthesis makes this a useful methodology for the expedient modification and assembly of sterically congested 1-indanone-containing ring systems.

The deliberate inoculation of yeast strains isolated from food matrices such as wine or bread, could allow the transfer of novel properties to beer. In this work, the feasibility of the use of baker's yeast strains as starters for craft beer production has been evaluated at laboratory and brewery scale. Nine out of 12 Saccharomyces cerevisiae strains isolated from artisanal sourdoughs metabolized 2 % maltose, glucose and trehalose and showed growth rates and cell populations higher than those of the brewer's strain Safbrew-S33. Analysis of allelic variation at 12 microsatellite loci clustered seven baker's strains and Safbrew-S33 in the main group of bread isolates. Chemical analyses of beers produced at a brewery scale showed significant differences among the beers produced with the baker's strain S38 or Safbrew-S33, while no significant differences were observed when S38 or the brewer's strain Safbrew-F2 was used for re-fermentation. The sensory profile of beers obtained with S38 or the brewer's yeasts did not show significant differences, thus suggesting that baker's strains of S. cerevisiae could represent a reservoir of biodiversity for the selection of starter strains for craft beer production.

Uncovering patterns of consumers' interest for beer: A case study with craft beers.

2017-01-01

To uncover patterns of consumer interest in craft beers, the authors explored the quality perception of craft beers in a panel of industrial mass-marketed beer drinkers (n=150) and examined the differences in interest for this beer segment between men and women. The authors adopted a conjoint rating experiment in which the respondents were given forty-nine beer profiles to evaluate and were asked to score the degree of interest in each profile on a 9-point scale. Each profile was described on eight attributes (type of brewery, brewing technology, characterizing raw materials, brewhouse equipment, location of the brewery, type of container, retail price, where to buy) varied at different levels. Results showed that Italian consumers placed greatest importance on type of container (30.49%) and on brewing technology (17.64%). Characterizing raw materials (13.44%) and type of brewery (12.64) rank 3 and 4 and were placed in the same band some way below brewing technology. Retail price (9.87%) and where to buy (8.73%) were of far less importance. The least importance of all was attached to brewhouse equipment (4.44%) and to location of the brewery (2.75%). As far as utility values are concerned, the factor level glass bottle+crown cap and the factor level microfiltration are the utilities that most increased the interest of consumers. They were followed by the factor level local grains, stainless steel keg and monastery. In contrast, the factor level PET Keg, aluminum can and large scale corporate brewery showed the greatest negative impact on interest. Men and women shared similar patterns of interest. However, men placed more importance than women on retail price, location of the brewery and where to buy. Women attached more importance than men on type of container, brewing technology and type of brewer.

Experimental and theoretical studies on the structure of several complexes based on (R)-3,3'-Br(2)-BINOL ligand and group (IV) metals used as catalysts in an enantioselective Friedel-Crafts alkylation of indoles with α,β-unsaturated ketones have been carried out. NMR spectroscopic studies of these catalysts have been performed, which suggested that at room temperature the catalysts would form a monomeric structure in the case of Ti(IV) and a dimeric structure in the cases of Zr(IV) and Hf(IV). Density functional theory (DFT) calculations clearly corroborate the conclusions of these experimental spectroscopic studies. The dimeric structure with a doubly bridged motif [Zr(IV)(2)(μ-(R)-3,3'-Br(2)-BINOL)(2)] where each binaphthol ligand acts as bridge between the metal centers (Novak's model) is more stable than the dimeric structure with a doubly bridged motif [Zr(IV)(2)(μ-O(t)Bu)(2)] where the tert-butoxide groups act as bridging ligands (Kobayashi's model). The scope of the Friedel-Crafts alkylation with regard to the indole structure has been studied. Finally a plausible mechanism for the Friedel-Crafts reaction and a stereomodel for the mode of action of the catalyst that explain the observed stereochemistry of the reaction products have been proposed.

A classical Friedel-Crafts alkylation of different indoles catalyzed by AlCl₃·6H₂O has been developed for a well-known important natural product, celastrol, resulting in a series of derivatives for further biological evaluation. The catalyst loading was reduced to 5 mol %, the reaction proceeds at ambient temperature and reaction time is only 3 h. The product yields range from 20% to 99%. A reaction mechanism is also proposed, based on our experiment results.

Crafting Sustainability: Handcraft in Contemporary Art and Cultural Sustainability in the Finnish Lapland

Directory of Open Access Journals (Sweden)

Elina Härkönen

2018-06-01

Full Text Available Crafting sustainability is discussed here with respect to the dimensions of handcraft traditions in contemporary art for promoting cultural sustainability in the Scandinavian North. Aspects of decolonization, cultural revitalisation, and intergenerational dialogue form an integral part of the negotiations around the need for cultural survival and renewal for a more sustainable future. These dimensions should also be considered in the development of the current education of art teachers. Learning traditional skills and applying them in contemporary art constitute an influential method when striving for cultural sustainability. This study examines three handcraft-based contemporary art cases through art-based action research conducted in the Finnish and the Swedish Lapland. The results show that handcraft-based contemporary art practices with place-specific intergenerational and intercultural approaches create an open space for dialogue where the values and the perceptions on cultural heritage can be negotiated.

"Slow food" post-qualitative research in psychology: old craft skills in new disguise?

Science.gov (United States)

Demuth, Carolin

2015-06-01

The present paper addresses several aspects discussed in the special issue on the future of qualitative research in psychology. Particularly, it asks whether in light of the overhomogenization of the term "qualitative methods" researchers actually can still assume that they talk about the same thing when using this terminology. In addressing the topic of what constitutes the object of psychological research and what accordingly could be a genuinely psychological qualitative research it acknowledges the need to return to the study of persons' unique experience. In light of the risk of "McDonaldization" in present qualitative research, it argues that we need to return to learning research methods as craft skills. It will then give an outlook on how recent developments in discursive and narrative psychology offer a fruitful avenue for studying unique psychological experience as people manage to 'move on' in a material world and in irreversible time.

New Methods for Crafting Locally Decision-Relevant Scenarios

Science.gov (United States)

Lempert, R. J.

2015-12-01

Scenarios can play an important role in helping decision makers to imagine future worlds, both good and bad, different than the one with which we are familiar and to take concrete steps now to address the risks generated by climate change. At their best, scenarios can effectively represent deep uncertainty; integrate over multiple domains; and enable parties with different expectation and values to expand the range of futures they consider, to see the world from different points of view, and to grapple seriously with the potential implications of surprising or inconvenient futures. These attributes of scenario processes can prove crucial in helping craft effective responses to climate change. But traditional scenario methods can also fail to overcome difficulties related to choosing, communicating, and using scenarios to identify, evaluate, and reach consensus on appropriate policies. Such challenges can limit scenario's impact in broad public discourse. This talk will demonstrate how new decision support approaches can employ new quantitative tools that allow scenarios to emerge from a process of deliberation with analysis among stakeholders, rather than serve as inputs to it, thereby increasing the impacts of scenarios on decision making. This talk will demonstrate these methods in the design of a decision support tool to help residents of low lying coastal cities grapple with the long-term risks of sea level rise. In particular, this talk will show how information from the IPCC SSP's can be combined with local information to provide a rich set of locally decision-relevant information.

Determination of partition coefficients using 1 H NMR spectroscopy and time domain complete reduction to amplitude-frequency table (CRAFT) analysis.

Soulsby, David; Chica, Jeryl A M

2017-08-01

We have developed a simple, direct and novel method for the determination of partition coefficients and partitioning behavior using 1 H NMR spectroscopy combined with time domain complete reduction to amplitude-frequency tables (CRAFT). After partitioning into water and 1-octanol using standard methods, aliquots from each layer are directly analyzed using either proton or selective excitation NMR experiments. Signal amplitudes for each compound from each layer are then extracted directly from the time domain data in an automated fashion and analyzed using the CRAFT software. From these amplitudes, log P and log D 7.4 values can be calculated directly. Phase, baseline and internal standard issues, which can be problematic when Fourier transformed data are used, are unimportant when using time domain data. Furthermore, analytes can contain impurities because only a single resonance is examined and need not be UV active. Using this approach, we examined a variety of pharmaceutically relevant compounds and determined partition coefficients that are in excellent agreement with literature values. To demonstrate the utility of this approach, we also examined salicylic acid in more detail demonstrating an aggregation effect as a function of sample loading and partition coefficient behavior as a function of pH value. This method provides a valuable addition to the medicinal chemist toolbox for determining these important constants. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

Multi-intelligence critical rating assessment of fusion techniques (MiCRAFT)

Science.gov (United States)

Blasch, Erik

2015-06-01

Assessment of multi-intelligence fusion techniques includes credibility of algorithm performance, quality of results against mission needs, and usability in a work-domain context. Situation awareness (SAW) brings together low-level information fusion (tracking and identification), high-level information fusion (threat and scenario-based assessment), and information fusion level 5 user refinement (physical, cognitive, and information tasks). To measure SAW, we discuss the SAGAT (Situational Awareness Global Assessment Technique) technique for a multi-intelligence fusion (MIF) system assessment that focuses on the advantages of MIF against single intelligence sources. Building on the NASA TLX (Task Load Index), SAGAT probes, SART (Situational Awareness Rating Technique) questionnaires, and CDM (Critical Decision Method) decision points; we highlight these tools for use in a Multi-Intelligence Critical Rating Assessment of Fusion Techniques (MiCRAFT). The focus is to measure user refinement of a situation over the information fusion quality of service (QoS) metrics: timeliness, accuracy, confidence, workload (cost), and attention (throughput). A key component of any user analysis includes correlation, association, and summarization of data; so we also seek measures of product quality and QuEST of information. Building a notion of product quality from multi-intelligence tools is typically subjective which needs to be aligned with objective machine metrics.

From reading to writing: Evaluating the Writer's Craft as a means of assessing school student writing

Directory of Open Access Journals (Sweden)

Pauline Sangster, Graeme Trousdale & Charles Anderson

2012-06-01

Full Text Available This article reports on part of a study investigating a new writing assessment, the Writer's Craft, which requires students to read a stimulus passage and then write a continuation adopting the style of the original. The article provides a detailed analysis of stimulus passages employed within this assessment scheme and students' written continuations of these passages. The findings reveal that this is a considerably more challenging assessment writing task than has previously been recognised; and that questions arise concerning the nature of the stimulus passages and the extent to which the assessment criteria captured what the students had achieved in their writing. The implications of these findings are discussed and recommendations are made.

Causal factors in accidents of high-speed craft and conventional ocean-going vessels

International Nuclear Information System (INIS)

Antao, Pedro; Guedes Soares, C.

2008-01-01

An analysis of 40 ocean-going commercial vessel accidents is compared with the study of a similar number of high-speed crafts (HSCs) accidents, using in both cases a methodology that highlights the sequence of events leading to the accident and identifies the associated latent or causal factors. The main objective of this study was to identify and understand the difference in the pattern of causal factors associated with HSC accidents, as compared with the more traditional ocean-going ships. From the analysis one can see that the HSC accidents are mainly related to bridge personnel and operations, where the human element is the key factor identified as being responsible for the majority of the accidents. When compared with ocean-going commercial vessels, it is clear that navigational equipment and procedures have a larger preponderance in terms of the occurrence of accidents of HSC and particular attention should be given to these issues

Crafting interactivity for stakeholder engagement: transforming assumptions about communication in science and policy.

Science.gov (United States)

Aakhus, Mark

2011-11-01

The International Radiation Protection Association's guiding principles for stakeholder engagement focus on fostering, facilitating, and enabling interaction among stakeholders that is inclusive and fosters competent decision making. Implicit in these standards is a call to cultivate knowledge and competence in designing communication for stakeholder engagement among radiation protection professionals. Communication as design is an approach to risk communication in science and policy that differs from, yet complements, the more well-known communication practices of informing and persuading. Design focuses on the recurring practical problem faced by professionals in making communication possible among stakeholders where it has otherwise been difficult, impossible, or even unimagined. The knowledge and competence associated with design involves principles for crafting interactivity across a variety of mediated and non-mediated encounters among stakeholders. Risk communication can be improved by cultivating expertise in scalable communication design that embraces the demands of involvement without abandoning the need for competence in science and policy communication.

PEDAGOGICAL SUPPORT OF GIFTED STUDENTS FROM CARPATHIAN MOUNTAIN AREAS BY MEANS OF FOLK ART CRAFTS

2015-04-01

Full Text Available This paper, presented at the Conference Plenary the possibilities of pedagogical support of gifted students from vocational schools, living in the mountainous areas of the Carpathians. Education of talented and gifted students requires pedagogical support. The specific conditions, in which Carpathian students live, require the development of pedagogical support of their abilities. New approaches to teaching science, which led to the selection of topics of this article are described. Gifted personalities differ from their peers by same criterias. The social aspect of the problem remains in the shadow: not to be ashamed of your talent and not to compare it with cliches. And goals of educators and psychologists have to be slightly different as is common. Widespread  Carpathian crafts include: embroidery, artistic textiles producing, carpet manufacture, carving, pottery, metalworking, fabric painting, knitting, lace, artistic weaving, artistic working of  leather, stones, bones and horns. Nowadays, some detachment of mountainous regions has significantly reduced due to new means of communication, including the Internet. The possibilities of colleges in mountainous regions still cannot reach the level of the colleges in capital. In Carpathian and Prykrpattya regions there is a number of vocational schools of art direction. During the execution of creative work in class industrial training necessary for students to comply with the rules of relationships form and decoration in various ways: decorative motif obeys the functional form, enriching it artistic and creative solutions, utilitarian function obeys the decorative motif Products, the form of the product can be extremely decorative, artistic and creative product solutions focused on practical value and decorative value of the product. Pedagogical support of gifted students from art colleges in the Carpathian region has extremely wide range of opportunities. The problem of finding and nurturing

Detail in architecture: Between arts & crafts

Science.gov (United States)

Dulencin, Juraj

2016-06-01

Architectural detail represents an important part of architecture. Not only can it be used as an identifier of a specific building but at the same time enhances the experience of the realized project. Within it lie the signs of a great architect and clues to understanding his or her way of thinking. It is therefore the central topic of a seminar offered to architecture students at the Brno University of Technology. During the course of the semester-long class the students acquaint themselves with atypical architectural details of domestic and international architects by learning to read them, understand them and subsequently draw them by creating architectural blueprints. In other words, by general analysis of a detail the students learn theoretical thinking of its architect who, depending on the nature of the design, had to incorporate a variety of techniques and crafts. Students apply this analytical part to their own architectural detail design. The methodology of the seminar consists of experiential learning by project management and is complemented by a series of lectures discussing a diversity of details as well as materials and technologies required to implement it. The architectural detail design is also part of students' bachelors thesis, therefore, the realistic nature of their blueprints can be verified in the production process of its physical counterpart. Based on their own documentation the students choose the most suitable manufacturing process whether it is supplied by a specific technology or a craftsman. Students actively participate in the production and correct their design proposals in real scale with the actual material. A student, as a future architect, stands somewhere between a client and an artisan, materializes his or her idea and adjusts the manufacturing process so that the final detail fulfills aesthetic consistency and is in harmony with its initial concept. One of the very important aspects of the design is its economic cost, an

We have exposed stacks of CR-39 plastic nuclear track detectors inside the MIR space craft during the EUROMIR95 space mission for almost 6 months. Over this long period a large number of tracks of high LET events was accumulated in the detector foils. The etching and measuring conditions for this experiment were optimized to detect tracks of stopping iron nuclei. We found 185 stopping iron nuclei inside the stack and identified their trajectories through the material of the experiment. Based on the energy-range relation the energy at the surface of the stack was determined. These particles allow the determination of the low energy part of the spectrum of iron nuclei behind shielding material inside the MIR station

Chemometric classification models were built on the separate blocks using soft independent modeling of class analogies (SIMCA) and partial least squares-discriminant analysis (PLS-DA) obtaining good predictive ability on an external test set (75% or higher depending on the technique). The use of data fusion strategies – in particular, the mid-level one – to integrate the data from the different platforms allowed the correct classification of all the training and validation samples.

Concerning the Charging of an Exploration Craft on and near a Small Asteroid

Jackson, T. L.; Zimmerman, M. I.; Farrell, W. M.

2014-01-01

Introduction: An object immersed in an airless plasma environment will experience a natural process of surface charging in order to acheieve current balance, or zero net electric current to the object. It has been shown in recent computer simulations that the small-body plasma environment is very complex [1], considering effects of photoemission, topography, and formation of a plasma wake. For this work we consider an exploration craft (or astronaut) immersed within a plasma environment near an asteroid, which exhibits widely varying solar wind and photoelectric particle fluxes and continuously evolving illumination conditions. Objective: We aim to determine how an explo-ration craft or astronaut suit accumulates charge while located in the "nightside" asteroid wake where the particle fluxes are reduced, and in the dayside near-surface photoelectron sheath, by combining an object charging model [2] with kinetic simulations of a near-asteroid plasma environment [1]. We consider an astronaut floating near the asteroid while not in contact with the surface, as well as an astronaut moving along the surface using their hands/gloves to crawl along. Results: The modeling results suggest that remediation of triboelectric charge via accumulation of plasma currents is an important factor to consider when designing future NEA mission infrastructure, especially if repeated and frequent contact with the surface is planned. In shadowed regions such as the location shown in Fig. 1a, the plasma currents are so low (and the effective charge-remediation timescale so long, e.g. minutes to hours) that repeated contact with the surface tribocharges the glove in an uncontrollable fashion, as shown for two representative electron temperatures in Fig. 2a. The resulting buildup of significant negative charge would eventually initiate some other "current of last resort" [4] such as transport of positively-charged dust, field-emission from the glove, or significant alteration of

Little is known about the transition to adulthood in traditional, developing countries such as Saudi Arabia. Previous research in other countries has revealed the importance of considering parents' support during the transition to adulthood. Thus, the purpose of this research was to examine how two generations negotiated the transition to adulthood. We asked the research question, What are the joint projects in which parents and youth plan and act on their plans for the youth's future? We used the action project method, an established qualitative approach, to answer these questions by observing the joint conversations of 14 parent and youth dyads. Our results provided evidence of an overarching higher level goal, or intentional framework, of crafting generational change and continuity within which participants' joint projects were embedded. Joint projects were organized into three groups: (a) negotiating educational and career futures, (b) promoting gender roles and marriage, and (c) shaping independence.

The craft of scientific presentations critical steps to succeed and critical errors to avoid

Alley, Michael

2013-01-01

The Craft of Scientific Presentations, 2nd edition aims to strengthen you as a presenter of science and engineering. The book does so by identifying what makes excellent presenters such as Brian Cox, Jane Goodall, Richard Feynman, and Jill Bolte Taylor so strong. In addition, the book explains what causes so many scientific presentations to flounder. One of the most valuable contributions of this text is that it teaches the assertion-evidence approach to scientific presentations. Instead of building presentations, as most engineers and scientists do, on the weak foundation of topic phrases and bulleted lists, this assertion-evidence approach calls for building presentations on succinct message assertions supported by visual evidence. Unlike the commonly followed topic-subtopic approach that PowerPoint leads presenters to use, the assertion-evidence approach is solidly grounded in research. By showing the differences between strong and weak presentations, by identifying the errors that scientific presenters ty...

Modeling Ships and Space Craft: The Science and Art of Mastering the Oceans and Sky begins with the theories of Aristotle and Archimedes, moving on to examine the work of Froude and Taylor, the early aviators and the Wright Brothers, Goddard and the other rocket men, and the computational fluid dynamic models of our time. It examines the ways each used fluid dynamic principles in the design of their vessels. In the process, this book covers the history of hydrodynamic (aero and fluid) theory and its progression – with some very accessible science examples – including seminal theories. Hydrodynamic principles in action are also explored with examples from nature and the works of man. This is a book for anyone interested in the history of technology – specifically the methods and science behind the use of scale models and hydrodynamic principles in the marine and aeronautical designs of today.

1-acetylvinyl acrylates: new captodative olefins bearing an internal probe for the evaluation of the relative reactivity of captodative against electron-deficient double bonds in Diels-Alder and Friedel-Crafts reactions

2005-01-01

The captodative olefins 1-acetylvinyl esters of methacrylic and trans-crotonic acids, 3a and 3b, have been prepared. The presence of a second double bond in the molecule, acting as an internal probe, allowed us to compare their relative reactivity in Diels-Alder and Friedel-Crafts reactions. The reactivity was evaluated with cyclopentadiene (6) as diene in Diels-Alder cycloadditions, and with furan (9) and thiophene (10) as heteroaromatic Friedel-Crafts substrates. In both processes, the captodative enone double bond proved to be more reactive than that in the acrylic moiety. FMO theory accounted for this chemo selectivity as a consequence of the major π contribution of the enone to the LUMO of these molecules. The slight exo stereoselectivity observed in the cycloaddition to 6 parallels the higher stability of the corresponding transition state, according to the results of B3LYP/6-311G(d,p) calculations.

Full Text Available In 2012, the Italian Ministry for Territorial Cohesion launched the ‘National Strategy for Inner Areas’ (SNAI, a development strategy aimed at enhancing the quality of life and the access to essential services (health, education and transport in areas considerably far from urban centres, which have been suffering from processes of increasing marginalisation and de-anthropisation since the 1950s. The current contribution focuses on how tourism is locally interpreted in peripheral areas, taking the cue from a wider research on the implementation of SNAI in the Marche’s Apennines carried out between 2015 and 2016. The underlying hypothesis is that the creation of a tourism market in such areas requires, on the one hand, the selection of few cultural traits perceived as more ‘charismatic’, often enhanced through dedicated events, and, on the other, the creation of new potential attractors in line with the expectations of prospective rural tourists. In particular, the ‘Alogastronomia’ phenomenon will be analysed, highlighting the cultural and environmental factors which have brought the local administration to create a territorial marketing strategy linked to a peculiar craft beer and gastronomic culture, and considering whether specific niche tourism can contribute to giving some kind of ‘centrality’ to areas otherwise considered as marginal.

Pollutant on the leaves and pinecones of Pinus thunbergii contaminated by radiocesium in Fukushima City were measured, the safe use of the leaves and pinecones as children's toys and craft materials was prospected after the accident at the TEPCO's Fukushima Daiichi nuclear power plant. The radiocesium concentration on Pinus thunbergii leaves on February 22, 2013 was 1/5.7 of the concentration on May 2, 2012. The radiocesium concentration on pinecones was high (16,300 Bq/kg). Radiocesium attached to the latex glove worn when collecting polluted pinecones, and this level fell by 1/5.2 when the polluted glove was washed. Negligible amount of radiocesium was detected in the used glove for collecting of dirty pinecones after painting. It is reasonable to assume that the use of pinecones as craft materials will be possible in the near future because the radiocesium concentration levels are expected to decrease after 2014. (author)

4-Acyloxy-2,5-diphenyl-3-oxo-2,3-dihydrothiophene 1,1-dioxides as acylating agents in the Friedel-Crafts reaction

1989-01-01

The 'activated esters', 4-acyloxy-2,5-diphenyl-3-oxo-2,3-dihydrothiophene 1,1-dioxides, easily accessible from 4,6-diphenylthieno[3,4-d][1,3]dioxol-2-one 5,5-dioxide, have been found to be excellent acylating agents in the Friedel-Crafts reaction with olefins and activated aromatic compounds. In the case of the olefins, product mixtures containing β-chloroketones were treated with 1,8-diazabicyclo[5.4.0]undex-7-ene to afford the corresponding unsaturated ketones in 30 - 73% yields, whereas aromatic ketones were obtained in high yields. The activated esters react slightly faster than the corresponding alkanoyl chlorides, and form fewer by-products

Full Text Available In cities across the Soviet Union in the late 1950s and early 1960s, new housing developments of plain five-storey apartment blocks mushroomed thanks to an intensive programme for mass industrialised housing construction launched by the Party-State in 1957. Modern living conditions were to be created for millions, it was promised, through state planning and investment in the modernisation of construction, making maximum use of technology and factory prefabrication in place of bricklaying and other artisanal methods. Drawing on oral history and material culture, this article attends to some contradictory, seemingly unplanned and un-modern aspectsof popular agency entailed in producing the modern Soviet environment, including the role of local improvisation, DIY and manual craft. These were not necessarily resistant to or subversive of the socialist state's modernisationproject but had a more complex and ambivalent relation to it, as complementary or compensatory accommodations that"tuned" universal modelsto local contingency.

Free Software Beyond Radical Politics: Negotiations of Creative and Craft Autonomy in Digital Visual Media Production

Directory of Open Access Journals (Sweden)

Julia Velkova

2016-08-01

Full Text Available Free software development and the technological practices of hackers have been broadly recognised as fundamental for the formation of political cultures that foster democracy in the digital mediascape. This article explores the role of free software in the practices of digital artists, animators and technicians who work in various roles for the contemporary digital visual media industries. Rather than discussing it as a model of organising work, the study conceives free software as a production tool and shows how it becomes a locus of politics about finding material security in flexible capitalism. This politics is ultimately contradictory in that it extends creative and craft autonomy of digital artists but does not mobilise a critical project. Instead, it nurtures further precarious labour. Empirically, the article draws on ethnographically collected material from the media practices of digital artists and programmers who engage with two popular free software production tools, Blender and Synfig.

This article reviews an improved methodology and technology for crafting a multi-electrode spiral cuff for the selective activation of nerve fibres in particular superficial regions of a peripheral nerve. The analysis, structural and mechanical properties of the spot welds used for the interconnections between the stimulating electrodes and stainless-steel lead wires are presented. The cuff consisted of 33 platinum electrodes embedded within a self-curling 17-mm-long silicone spiral sheet with a nominal internal diameter of 2.5 mm. The weld was analyzed using scanning electron microscopy and nanohardness tests, while the interconnection was investigated using destructive load tests. The functionality of the cuff was tested in an isolated porcine vagus nerve. The results of the scanning electron microscopy show good alloying and none of the typical welding defects that occur between the wire and the platinum foil. The results of the destructive load tests show that the breaking loads were between 3.22 and 5 N. The results of the nanohardness testing show that the hardness of the weld was different for the particular sites on the weld sample. Finally, the results of the functional testing show that for different stimulation intensities both the compound action potential deflection and the shape are modulated.

Future missions to Mars that would need a sophisticated lander, hopper, or rover could benefit from the REARM Architecture. The mission concept REARM Architecture is designed to provide unprecedented capabilities for future Mars exploration missions, including human exploration and possible sample-return missions, as a reusable lander, ascend/descend vehicle, refuelable hopper, multiple-location sample-return collector, laboratory, and a cargo system for assets and humans. These could all be possible by adding just a single customized Re-Entry-Hopper-Aero-Space-Craft System, called REARM-spacecraft, and a docking station at the Martian orbit, called REARM-dock. REARM could dramatically decrease the time and the expense required to launch new exploratory missions on Mars by making them less dependent on Earth and by reusing the assets already designed, built, and sent to Mars. REARM would introduce a new class of Mars exploration missions, which could explore much larger expanses of Mars in a much faster fashion and with much more sophisticated lab instruments. The proposed REARM architecture consists of the following subsystems: REARM-dock, REARM-spacecraft, sky-crane, secure-attached-compartment, sample-return container, agile rover, scalable orbital lab, and on-the-road robotic handymen.

Large international investigations into the learning of science, such as the TIMSS and PISA studies, have been enlightening with regard to effective instructional practices. Data from these studies revealed weaknesses and promising practices within nations' educational systems, with evidence to suggest that these studies have led to international reforms in science education. However, these reforms have focused on the general characteristics of teaching and learning across all sciences. While extraordinarily useful, these studies have provided limited insight for any given content domain. To date, there has been no systematic effort to measure individual's conceptual astronomy understanding across the globe. This paper describes our motivations for a coordinated, multinational study of astronomy understanding. First, reformed education is based upon knowing the preexisting knowledge state of our students. The data from this study will be used to assist international astronomy education and public outreach (EPO) professionals in their efforts to improve practices across global settings. Second, while the US astronomy EPO community has a long history of activity, research has established that many practices are ineffective in the face of robust misconceptions (e.g.: seasons). Within an international sample we hope to find subpopulations that do not conform to our existing knowledge of student misconceptions, leading us to cultural or educational practices that hint at alternative, effective means of instruction. Finally, it is our hope that this first venture into large-scale disciplinary collaboration will help us to craft a set of common languages and practices, building capacity and leading toward long-term cooperation across the international EPO community. This project is sponsored and managed by the Center for Astronomy & Physics Education Research (CAPER), in collaboration with members of the International Astronomical Union-Commission 46.

Full Text Available I studied how artificial intelligence (AI adapts to failure. I worked with AI framework ABL, which uses a behavior tree. The tree begins by creating behaviors to accomplish an AI goal. Behaviors are chosen based on priorities. However, these priorities are not effective in all situations, and cannot change in ABL, which prevents the AI to learn from failure. For my study, I gave ABL the ability to change its priorities. This essentially allows an ABL AI to adapt from its mistakes. This ability was then tested for effectiveness using the ABL AI EISBot (an AI that plays videogames and the game of StarCraft. The new ability caused EISBot to improve significantly showing that the ability to change priorities improves an AI’s performance.

Postural Stability of Special Warfare Combatant-Craft Crewmen With Tactical Gear.

Morgan, Paul M; Williams, Valerie J; Sell, Timothy C

The US Naval Special Warfare's Special Warfare Combatant-Craft Crewmen (SWCC) operate on small, high-speed boats while wearing tactical gear (TG). The TG increases mission safety and success but may affect postural stability, potentially increasing risk for musculoskeletal injury. Therefore, the purpose of this study was to examine the effects of TG on postural stability during the Sensory Organization Test (SOT). Eight SWCC performed the SOT on NeuroCom's Balance Manager with TG and with no tactical gear (NTG). The status of gear was performed in randomized order. The SOT consisted of six different conditions that challenge sensory systems responsible for postural stability. Each condition was performed for three trials, resulting in a total of 18 trials. Overall performance, each individual condition, and sensory system analysis (somatosensory, visual, vestibular, preference) were scored. Data were not normally distributed therefore Wilcoxon signed-rank tests were used to compare each variable (ρ = .05). No significant differences were found between NTG and TG tests. No statistically significant differences were detected under the two TG conditions. This may be due to low statistical power, or potentially insensitivity of the assessment. Also, the amount and distribution of weight worn during the TG conditions, and the SWCC's unstable occupational platform, may have contributed to the findings. The data from this sample will be used in future research to better understand how TG affects SWCC. The data show that the addition of TG used in our study did not affect postural stability of SWCC during the SOT. Although no statistically significant differences were observed, there are clinical reasons for continued study of the effect of increased load on postural stability, using more challenging conditions, greater surface perturbations, dynamic tasks, and heavier loads. 2016.

Highly conductive and low vanadium permeable crosslinked sulfonated poly(ether ether ketone) (cSPEEK) membranes were prepared by electrophilic aromatic substitution for a Vanadium/Air Redox Flow Battery (Vanadium/Air-RFB) application. Membranes were synthesized from ethanol solution and crosslinked under different temperatures with 1,4-benzenedimethanol and ZnCl2 via the Friedel-Crafts crosslinking route. The crosslinking mechanism under different temperatures indicated two crosslinking pathways: (a) crosslinking on the sulfonic acid groups; and (b) crosslinking on the backbone. It was observed that membranes crosslinked at a temperature of 150 °C lead to low proton conductive membranes, whereas an increase in crosslinking temperature and time would lead to high proton conductive membranes. High temperature crosslinking also resulted in an increase in anisotropy and water diffusion. Furthermore, the membranes were investigated for a Vanadium/Air Redox Flow Battery application. Membranes crosslinked at 200 °C for 30 min with a molar ratio between 2:1 (mol repeat unit:mol benzenedimethanol) showed a proton conductivity of 27.9 mS/cm and a 100 times lower VO2+ crossover compared to Nafion.

2016-09-01

Users of darknet markets refer to product quality as one of the motivations for buying drugs there, and vendors present quality as a selling point. However, what users understand by quality and how they evaluate it is not clear. This article investigates how users established and compared drug quality. We used a two-stage method for investigating users' assessments. The user forum of a darknet market that we called 'Merkat' was analysed to develop emergent themes. Qualitative interviews with darknet users were conducted, then forum data was analysed again. To enhance the applicability of the findings, the forum was sampled for users who presented as dependent as well as recreational. Quality could mean reliability, purity, potency, and predictability of effect. We focused on the different kinds of knowledge users drew on to assess quality. These were: embodied; craft; and chemical. Users' evaluations of quality depended on their experience, the purpose of use, and its context. Market forums are a case of indigenous harm reduction where users share advise and experiences and can be usefully engaged with on these terms. Copyright © 2015 Elsevier B.V. All rights reserved.

From Dalek half balls to Daft Punk helmets: Mimetic fandom and the crafting of replicas

Directory of Open Access Journals (Sweden)

Matt Hills

2014-06-01

Full Text Available Mimetic fandom is a surprisingly understudied mode of (culturally masculinized fan activity in which fans research and craft replica props. Mimetic fandom can be considered as (inauthentic and (immaterial, combining noncommercial status with grassroots marketing or brand reinforcement as well as fusing an emphasis on material artifacts with Web 2.0 collective intelligence. Simply analyzing mimetic fandom as part of fannish material culture fails to adequately assess the nonmaterial aspects of this collaborative creativity. Two fan cultures are taken as case studies: Dalek building groups and Daft Punk helmet constructors. These diverse cases indicate that mimetic fandom has a presence and significance that moves across media fandoms and is not restricted to the science fiction, fantasy, and horror followings with which it is most often associated. Mimetic fandom may be theorized as an oscillatory activity that confuses binaries and constructions of (academic/fan authenticity. This fan practice desires and pursues a kind of ontological bridging or unity—from text to reality—that is either absent or less dominant in many other fan activities such as cosplay, screen-used prop collecting, and geographical pilgrimage. Fan studies may benefit from reassessing the place of mimesis, especially in order to theorize fan practices that are less clearly transformative in character.

Cu(3)(BTC)(2) as a viable heterogeneous solid catalyst for Friedel-Crafts alkylation of indoles with nitroalkenes.

2017-05-15

In the present work, Friedel-Crafts alkylation reaction of indole with β-nitrostyrene is examined using a readily available copper based metal-organic frameworks (MOFs) namely, Cu 3 (BTC) 2 (BTC: 1,3,5-benzenetricarboxylic acid) as solid catalyst under mild reaction conditions. Among the various catalysts screened for this reaction, Cu 3 (BTC) 2 exhibits higher activity under the optimized reaction conditions. Besides the absence of leaching of active sites, it is also observed that the catalyst can be reused for four cycles with a minimal decrease in its activity. Cu 3 (BTC) 2 is used as a catalyst to synthesise a series of heterocyclic compounds with different indole and β-nitrostyrene derivatives in moderate to high yields. The present catalytic system shows comparable activity against to recent reports but the advantage of Cu 3 (BTC) 2 is that it does not require any post-functionalization and above all it can be readily synthesised, thus contributing to the synthesis of heterocyclic compounds with high biological interest.

At the request of the US Department of Energy (DOE), a team from Oak Ridge National Laboratory conducted a radiological survey at the former Alba Craft Laboratory Site Properties, Oxford, Ohio. The survey was performed in July and September of 1992. The purpose of the survey was to determine whether the property was contaminated with radioactive residues, primarily 238 U, from uranium machining operations conducted for National Lead of Ohio, a prime Atomic Energy Commission contractor. The survey included scan measurement of direct radiation levels inside and outside the former laboratory, outdoors on eight properties adjoining the former laboratory, and the city right-of-way adjacent to the surveyed properties. Radionuclide concentrations were determined in outdoor surface and subsurface soil samples taken from each property and the exterior of the laboratory. Fixed surface residual radioactivity was measured inside the laboratory and outside the building. Air samples were collected, direct exposure was measured, and samples were collected to measure transferable radioactivity inside the building. Results of the survey indicate areas where surface and soil contamination level s are above the DOE guidelines for uncontrolled areas

„Sirogojno Style“: The Production and Distribution of Hand-crafted Objects/Products Made of Wool

Directory of Open Access Journals (Sweden)

Senka Kovač

2016-03-01

Full Text Available The basic premise of my research regarding the fashion production of Sirogojno style was that „objects are, like words, carriers of information“. Based on research published so far – a paper by Bojana Bogdanovic being the most detailed – and my own fieldwork conducted in 2010, I have attempted to ascertain the extent to which this particular style of fashion carried information about the cultural environment which it represented. The research encompasses the study of the materials being used, the production and the sale of products made of wool. The development of this particular style was influenced by the enthusiasm of designer Dobrila Vasiljevic-Smiljanic and the women of the mt. Zlatibor region, as well as the support provided by the political structure of the period, the local government, and through Dobrila Vasiljevic-Smiljanic’s family ties – the church. Her creations are famous for incorporating adapted local ornaments. A distinct and recognizable style of woolen products was created. This „Wool Road“ – from using local raw materials to materials imported from Iceland, from creating unique motifs to sale in the open, from national and international sales to musealized sales in the first decade of the 21st century – has lasted for over fifty years. Products from Sirogojno were renowned both in the country and abroad. All the negative processes which happened during the nineties influenced the decline of production and distribution of hand-crafted products from Sirogojno. In the late 1990’s, the production was acquired by a local owner who didn’t show much interest in it. This production has been musealized in the first decade of the 21st century. Dobrila Vasiljevic-Smiljanic told me in 2010 that „everything should be started from scratch now, from new motifs to new marketing“. The new owners of the firm say that „the villages are deserted and there aren’t enough weavers“. On the other hand, there is sale

Study of a 30-M Boom For Solar Sail-Craft: Model Extendibility and Control Strategy

Science.gov (United States)

Keel, Leehyun

2005-01-01

Space travel propelled by solar sails is motivated by the fact that the momentum exchange that occurs when photons are reflected and/or absorbed by a large solar sail generates a small but constant acceleration. This acceleration can induce a constant thrust in very large sails that is sufficient to maintain a polar observing satellite in a constant position relative to the Sun or Earth. For long distance propulsion, square sails (with side length greater than 150 meters) can reach Jupiter in two years and Pluto in less than ten years. Converting such design concepts to real-world systems will require accurate analytical models and model parameters. This requires extensive structural dynamics tests. However, the low mass and high flexibility of large and light weight structures such as solar sails makes them unsuitable for ground testing. As a result, validating analytical models is an extremely difficult problem. On the other hand, a fundamental question can be asked. That is whether an analytical model that represents a small-scale version of a solar-sail boom can be extended to much larger versions of the same boom. To answer this question, we considered a long deployable boom that will be used to support the solar sails of the sail-craft. The length of fully deployed booms of the actual solar sail-craft will exceed 100 meters. However, the test-bed we used in our study is a 30 meter retractable boom at MSFC. We first develop analytical models based on Lagrange s equations and the standard Euler-Bernoulli beam. Then the response of the models will be compared with test data of the 30 meter boom at various deployed lengths. For this stage of study, our analysis was limited to experimental data obtained at 12ft and 18ft deployment lengths. The comparison results are positive but speculative. To observe properly validate the analytic model, experiments at longer deployment lengths, up to the full 30 meter, have been requested. We expect the study to answer the

The SXRD, N_2-physisorption and TEM characterization techniques indicated that M-ZrO_2/SO_4"2"− possessed distinct mesostructure with big specific surface area (133.5 m"2 g"−"1), large pore volume (0.18 cm"3 g"−"1) and narrow pore size distribution (4.90 nm). Moreover, the existing states and the influence in mesostructure of introduced S species were detailedly investigated by the XRD, N_2-physisorption, TEM, TG-DSC, FT-IR and XPS techniques and the results showed that the S species, which existed as the type of SO_4"2"−, improved the textural properties of prepared materials. In addition, the NH_3-TPD and IR spectra of adsorbed pyridine indicated the existence of strong Brønsted and Lewis acid sites in M-ZrO_2/SO_4"2"− even evacuated at 400 °C. Furthermore, the M-ZrO_2/SO_4"2"− was used as a promise solid acid catalyst and displayed excellent catalytic performance and reusability in Friedel-Crafts benzylation reaction.

Semiconductor organic-inorganic hybrid solar cells incorporating conjugated polymers (CPs) and nanocrystals (NCs) offer the potential to deliver efficient energy conversion with low-cost fabrication. The CP-based photovoltaic devices are complimented by an extensive set of advantageous characteristics from CPs and NCs, such as lightweight, flexibility, and solution-processability of CPs, combined with high electron mobility and size-dependent optical properties of NCs. Recent research has witnessed rapid advances in an emerging field of directly tethering CPs on the NC surface to yield an intimately contacted CP-NC nanocomposite possessing a well-defined interface that markedly promotes the dispersion of NCs within the CP matrix, facilitates the photoinduced charge transfer between these two semiconductor components, and provides an effective platform for studying the interfacial charge separation and transport. In this Review, we aim to highlight the recent developments in CP-NC nanocomposite materials, critically examine the viable preparative strategies geared to craft intimate CP-NC nanocomposites and their photovoltaic performance in hybrid solar cells, and finally provide an outlook for future directions of this extraordinarily rich field.

This research aims to determine the longitudinal strength of passenger ship which was converted from Landing Craft Tank with 54 m of length as stated by BKI (Biro Klasifikasi Indonesia / Indonesian Classification Bureau). Verification of strength value is done to 4 (four) loading conditions which are (1) empty load condition during sagging wave, (2) empty load condition during hogging wave, (3) full load condition during sagging wave and (4) full load condition during hogging wave. Analysis is done using Finite Element Analysis (FEA) software by modeling the entire part of passenger ship and its loading condition. The back and upfront part of ship centerline were used as the boundary condition. From that analysis it can be concluded that the maximum stress for load condition (1) is 72,393 MPa, 74,792 MPa for load condition (2), 129,92 MPa for load condition (3), and 132,4 MPa for load condition (4). Longitudinal strength of passenger ship fulfilled the criteria of empty load condition having smaller stress value than allowable stress which is 90 MPa, and during full load condition with smaller stress value than allowable stress which is 150 MPa. Analysis on longitudinal strength comparison with entire ship plate thickness variation of ± 2 mm from initial plate was also done during this research. From this research it can be concluded that plate thickness reduction causes the value of longitudinal strength to decrease, while plate thickness addition causes the value of longitudinal strength to increase.

Radiation damage of variscite in historic crafts: Solarization, decolouration, structural changes and spectra from ionoluminescence

X-ray diffraction measurements, during halogen lamp illumination to simulate sunlight, (TXRD) show a phase transition from variscite (AlPO 4 .H 2 O) Messbach to variscite Lucin and a loss of the dark green colour. The differential-thermal and thermo-gravimetric (DTA-TG) analyses and thermoluminescence (TL) peaks all depict this first-order phase transition which takes place under sunlight. From the water vaporization temperature up to circa 650 deg. C, a second-order phase transition progressively occurs from variscite to berlinite (AlPO 4 ) by loss of a second unit of water with hydrogen bonded to the lattice. The ion beam luminescence (IBL) spectra of the Zamora variscite display a spectral band from 500 to 570 nm attributed to [UO 2 ] 2+ in phosphates, and another spectral band from 670 to 740 nm is linked with Cr(VI) 3+ defects situated in octahedral Al(VI) 3+ positions. In the hydrous variscite lattice, the Al-O and P-O chemical bonds are mainly covalent; with the degree of covalency of the P-O chemical bond significantly larger than of Al-O. This open structure of variscite, which has a crystal field of reduced strength, involves small shifts of the absorption bands which intensify the blue-green transmission producing the characteristic emerald colour of the dark green variscite of Zamora. These data provide a valuable basis for detection of solarization damage in historic crafts with inlaid variscite in the Museo del Prado (Madrid, Spain)

Sahin, S.; Selvi, S.

1980-01-01

The suitability of borated reflector drums has been investigated and shown as a control mechanism for space craft thermionic reactors with constant emitter heating using U-233 as fuel and beryllium to be moderator, mainly due to their extremce compactness and their very soft neutron sepctrum. The achievable change in ksub(eff) allows long-term control operation with success. The use of reflector drums keeps the cone diameter and the mass of the radiation shield on minimum. The distortion of the emitter heating field remains under acceptable tolerances, mainly due to the enhanced neutron production at the outer core region and the remaining reflector part between the boron layer and the core. All neutron physics calculations have been carried out using the multigroup Ssub(N) methods. Three data groups for r-theta-calculations in S 4 -P 1 approximation (16 space angles) have been evaluated from a 123-energy-groups data library using transport theoretical methods. (orig.) [de

The progress of economic globalization, the rapid growth of international trade, and the maritime transportation has played an increasingly significant role in the international supply chain. As a result, worldwide seaports have suffered from a central problem, which appears in the form of massive amounts of fuel consumed and exhaust gas fumes emitted from the ships while berthed. Many ports have taken the necessary precautions to overcome this problem, while others still suffer due to the presence of technical and financial constraints. In this paper, the barriers, interconnection standards, rules, regulations, power sources, and economic and environmental analysis related to ships, shore-side power were studied in efforts to find a solution to overcome his problem. As a case study, this paper investigates the practicability, costs and benefits of switching from onboard ship auxiliary engines to shore-side power connection for high-speed crafts called Alkahera while berthed at the port of Safaga, Egypt. The results provide the national electricity grid concept as the best economical selection with 49.03 percent of annual cost saving. Moreover, environmentally, it could achieve an annual reduction in exhaust gas emissions of CO2, CO, NO x , P.M, and SO2 by 276, 2.32, 18.87, 0.825 and 3.84 tons, respectively.

Full Text Available Background: In the reviewed paper we attempted to investigate the phonetic variation of the Central Podillia dialect on the example of some linguistic phenomena. We found out that many linguists studied the phonetic variation based on the Ukrainians' dialect speech. However, they did not study the terminology of folk crafts of the Central Podillia dialects, that's why we aim to describe the sound differences of the lexical units of this area. Purpose: The purpose of the analysis is to determine some phonetic phenomena of the Central Podillia dialect. First of all, there are changes within the stable word length (metathesis, substantive changes of one sound in the stable surround sound, and changes, accompanied by the word elongation or contraction (prosthesis, epenthesis, elision. Results: The analyzed dialects widely present the consonant changes within the stable word length (г → ґ, т → д, с → ш, з → ж…. The performed study characterizes the Central Podillia dialects by the vowel change within a stable word length – 5 cases. Sound changes are typical for the analyzed dialects affecting the dynamics of the word length (prosthetic sounds - [г], [в], [й], [і], [и]. In opposition to the phonetic processes that help to increase the length of the word, we observe the loss of the sound in the middle of the word in the Central Podillia dialects (reduction – [o], [й], [в]. Discussion: The analysis of some phonetic phenomena of the Central Podillia dialects proved the existence of phonetic features typical for the South-Western dialect. However, we determined the local sound differences of this area, which confirm the identity of the language of this region.

Sebastian, S.J.; Borcherding, J.D.

1979-05-01

The data for this study were collected at six nuclear power plant construction sites spread throughout the United States. The geographical distribution included two projects from the Midwest and one site from each the Deep South, North Central, Southwest, and Northeast regions of the nation. The range for stage of completion varied from between approximately four and seventy-seven percent. Two of the projects were utilizing boiling water reactors (BWR) while the balance of the sites made use of the pressurized water reactor (PWR) systems. All of the installations had generating capacities approximately equal to 1200 megawatts per unit. The primary objective of the study was to provide a comprehensive investigation of the most influential factors adversely affecting craft productivity by means of a sampling comprised of five hundred seventy-six union and open shop carpenters, electricians, and pipefitters. The overall average amount of time lost due to delays obtaining materials and tools, overcrowded working conditions, interferences between crews, postponements relating to quality control inspections, and waiting for and/or receiving instructions was estimated by the tradesmen to be 24.12 manhours per individual on a weekly basis. Thus, a minimum of 60.3% of each tradesman's time is lost due to one of the aforementioned predicaments. Conversely, this figure accounts for a maximum possible level of direct work activity equal to 39.7% and is not inclusive of any personal breaks or late starts/early quits. The combined mean duration that was speculated for rework activities at all six sites totaled 5.77 manhours per craftsman per week. The summation of these two estimates yields a value of 29.89 manhours showing that only slightly more than twenty-five percent of each worker's time is allocated to productive endeavors for activities being engaged in for the first time

Full Text Available The church is not like any other institution or organisation in society. Although the church is primarily invisible and spiritual, it is a visible organisation in the world, and it spans across borders of nations, languages and countries. John Calvin strongly rejected the notion that the church is only a spiritual organisation of which the visible administrative side is downplayed. The fellowship of the church must not only be seen as a mystical relation with Jesus Christ. During 2010, an empirical study was done on the extent to which congregations of the Reformed Churches of South Africa (RCSA adhere to the request to have a well-designed congregational strategy. The knowledge gained from a literature study on the science of Strategic Management and the results of the empirical study was combined into a framework for crafting and executing a congregational strategy. This framework can be used by congregational leaders to guide them through their own process of crafting and executing their unique congregational strategy.  The research was concluded with a recommendation that the Theological School of the RCSA should consider including a course on Strategic Management in the training syllabus of aspiring ministers. Considering that Strategic Management is a specialised management science, and external Strategic Management consultants tend to be expensive, the research also recommended that the Administrative Bureau of the RCSA consider employing their own Strategic Management consultant for the RCSA with the specific assignment of assisting and guiding all congregations with their congregational strategy. ’n Raamwerk vir die ontwerp en implementering van ’n gemeentestrategie in die plaaslike gemeentes van die Gereformeerde Kerke in Suid-Afrika. ’n Kerk is ’n unieke organisasie.

Using the normal mode analysis, the number of possible modes is obtained in a magnetized inhomogeneous plasma sheath formed during the motion of a space craft which consists of negative ions (due to dust) along with the positive ions and the isothermal electrons. In addition to three propagating modes with phase velocities λ 1 , λ 2 , and λ 3 such that λ 1 2 3 , two types of instabilities with growth rates γ 1 and γ 2 also occur in such a plasma sheath. The growth rate γ 1 is increased with the negative to positive ion density ratio r 0 , ion temperature T, and obliqueness θ of the magnetic field B 0 . The growth rate γ 2 of the other instability gets lower with the density ratio r 0 but gets higher with the temperature T. The growth rate γ 2 is sensitive to the temperature T, whereas the growth rate γ 1 gets prominently changed with the density ratio r 0 . The increase in the growth rate γ 1 with the obliqueness θ is more pronounced under the effect of stronger magnetic field. On other hand, the phase velocity λ 1 shows weak dependence on r 0 and T (though it gets larger) but it gets significantly changed (increased) for the larger obliqueness θ. The phase velocity λ 2 gets larger with r 0 , B 0 , and θ and becomes lower for the higher temperature T. The phase velocity λ 3 is decreased for the higher values of r 0 and B 0 and is increased for the larger values of T and θ

Full Text Available Le village de métier est un sujet d’étude attractif, mais rarement traité comme une forme d’agglomération industrielle ou abordé sous l’angle de la sociologie industrielle. Le développement actuel des villages de métier montre bien la présence intensive des entreprises de tailles variées et l’implication d’autres acteurs en dehors du milieu de production (par exemple les autorités locales, le milieu de l’éducation. L’introduction d’acteurs nouveaux implique le changement des relations existantes, contribuant ainsi à la mise en place d’une nouvelle configuration. L’objectif de cet article est de montrer que l’organisation des villages de métier, qui est conçue comme un type de district industriel, est marquée par l’instabilité ou le changement permanent de la configuration générale, mais aussi par une transformation interne des acteurs au sein du district. À travers une étude de cas à Bát Tràng – un centre de production céramique au nord du Viêt Nam – cet article a pour objectif de montrer comment des entreprises familiales se réorganisent en structure plus formalisée, comment elles mobilisent du capital social pour régler leurs difficultés et les stratégies d’innovation qu’elles développent.Craft village is an attractive research subject, however it is rarely treated as a form of industrial agglomeration or studied from industrial sociology perspective.

Full Text Available With the rapid advent of video games recently and the increasing numbers of players and gamers, only a tough game with high policy, actions, and tactics survives. How the game responds to opponent actions is the key issue of popular games. Many algorithms were proposed to solve this problem such as Least-Squares Policy Iteration (LSPI and State-Action-Reward-State-Action (SARSA but they mainly depend on discrete actions, while agents in such a setting have to learn from the consequences of their continuous actions, in order to maximize the total reward over time. So in this paper we proposed a new algorithm based on LSPI called Least-Squares Continuous Action Policy Iteration (LSCAPI. The LSCAPI was implemented and tested on three different games: one board game, the 8 Queens, and two real-time strategy (RTS games, StarCraft Brood War and Glest. The LSCAPI evaluation proved superiority over LSPI in time, policy learning ability, and effectiveness.

The first-line drugs for the treatment of non-valvular atrial fibrillation (AF) are non-vitamin K antagonist oral anticoagulants (NOACs), which are preferred over vitamin K antagonists (VKAs). There is some evidence that there are dis-crepancies between everyday clinical practice and the guidelines. The study aimed to compare the characteristics of patients on VKAs, dabigatran, and rivaroxaban in everyday practice (i.e. baseline characteristics, drug doses, risk factors for bleeding and thromboembolic events). Additionally, we assessed the frequency of prescription of different oral anticoagulants (OACs) in recent years. This study consisted of data from the multicentre CRAFT (MultiCentre expeRience in AFib patients Treated with OAC) study (NCT02987062). This was a retrospective analysis of hospital records of AF patients (hospitalised in the years 2011-2016) treated with VKAs (acenocoumarol, warfarin) and NOACs (dabigatran, rivaroxaban). A total of 3528 patients with non-valvular AF were enrolled in the CRAFT study. The total cohort consisted of 1973 patients on VKA, 504 patients on dabigatran, and 1051 patients on rivaroxaban. Patients on rivaroxaban were older (70.5 ± 13.1 years) and more often female (47.9%), compared with those on VKAs (67.0 ± 12.8 years, p < 0.001; 35.5%, p < 0.001) and on dabigatran (66.0 ± 13.9 years, p < 0.001; 38.9%, p = 0.001). Among NOACs, patients with persistent and permanent AF were more likely to receive rivaroxaban (54.7% and 73.4%, re-spectively) than dabigatran (45.3%, p < 0.001 and 26.6%, p = 0.002, respectively). Patients on rivaroxaban had higher risk of thromboembolic events (CHA2DS2VASc 3.9 ± 2.0, CHADS2 2.2 ± 1.4) than those on VKAs (3.3 ± 2.0, 1.9 ± 1.3) and on dabigatran (3.1 ± 2.0, 1.8 ± 1.3). Patients on rivaroxaban had also a higher rate of prior major bleeding (11.2%) than those on VKAs (6.7%, p < 0.001) and on dabigatran (7.3%, p = 0.02). Patients on lower doses of dabigatran and rivaroxaban had a

A study on the industrialization of building stones and industrial stone crafts - Study on the causes of stone contaminations

Hyun, Jeon Ki; Lee, Han Yeang [Korea Institute of Geology Mining and Materials, Taejon (Korea, Republic of)

1996-12-01

Causes of building stone contamination are acid rains in polluted areas, iron bearing minerals in stone itself, salts, sealants, cutting and grinding processes in stone factory and steel compounds structures such as stone anchors, bolts, rain culvert and guide frames. Contaminations on the building stone surface of Sejong culture center can be found around floor stones, stair stones, parterre stones, pillar stones and other outdoor stone panels. The parterre stones are contaminated by white tarnishes and rust flows are occurred on the surface of pillar stones and outdoor stone panels around entrance. Black tarnishes are cumulated on the pillar stones and other outdoor decorated stone panels and change the original granite color. Causes of building stone contaminations from Sejong culture center are wet method to attach stone panels, rust from steel compounds structures and air pollutants. Cement and mortar used from wet method react with sulfur dioxides in polluted air and from fine calcite crystals (white tarnish). Rusts from steel compounds structures such as rainwater culvert and steel guide frames can move to the stone surface by rain and leave rust flows on it. Pollutants (tar compounds, carbons, dusts, etc.) in air are cumulated with humidity on the stone surface and change color from white granite color to dusty dark color. Historical stone sculptures such as man and animal shaped stone crafts, tombstones, square stone tables in front of a tomb and guide and circumference stones around tomb in Royal Tombs (Donggu rung, Yung rung, Seoou rung and Hunin rung) distributed in Kyunggi province are contaminated by various moss and air pollutants and its original colors are deeply changed.

Full Text Available Since 19th century, Jepara has been wellknown for furniture and craftings. It is shown by the appcreciation from some people claiming Jepara as an intregrated region for furniture and craftings. In Jepara, making furniture and craftings activities have become ingrained part of culture, arts, economic, social and politic. It is difficult to seperate them from its history, as it is not clear the time and place of making furniture and craftings. Thus, tracking the history is necessary to do, to know the development of Jepara as an integrated region for furniture and craftings nowadays.

Mezcal, a traditional beverage that originated in Mexico, is produced from species of the Agavaceae family. The esters associated with the yeasts utilized during fermentation are important for improving the organoleptic properties of the beverage. We improved the ester contents in a mezcal beverage by using the yeast Kluyveromyces marxianus, which was engineered with the ATF1 gene. ATF1 expression in the recombinant yeast significantly increased compared with that in the parental yeast, but its fermentative parameters were unchanged. Volatile-organic-compound-content analysis showed that esters had significantly increased in the mezcal produced with the engineered yeast. In a sensory-panel test, 48% of the panelists preferred the mezcal produced from the engineered yeast, 30% preferred the mezcal produced from the wild type, and 15 and 7% preferred the two mezcal types produced following the routine procedure. Correlation analysis showed that the fruitiness/sweetness description of the mezcal produced using the ATF1-engineered K. marxianus yeast correlated with the content of the esters, whose presence improved the organoleptic properties of the craft mezcal beverage.

Ongoing changes in social structures, orientation, and value systems confront us with the growing necessity to address and understand transforming patterns of tolerance as well as specific aspects, such as social tolerance. Based on hierarchical analyses of the latest World Values Survey (2005......–08) and national statistics for 28 countries, we assess both individual and contextual aspects that influence an individual's perception of different social groupings. Using a social tolerance index that captures personal attitudes toward these groupings, we present an institutional theory of social tolerance. Our...

programs therefore requires recognizing these limitations, which could lead to muscle diseases, high rates of absenteeism and decreased productivity. Objectives Determine the ergonomic risk profile of the craft and jewelry snuff in the region of Santander, Colombia in 2010. Methods: This survey was a descriptive cross-sectional study where people were surveyed companies manufacturing sub-sectors of the tobacco and handmade jewelry. The main unit of analysis was the company. He filled out an instrument that identified ergonomic features of the culture of the companies. Results: We interviewed 15 tobacco companies and 10 jewelers. Companies do not have policies on occupational health in 73% to snuff sector and 80% for the jewelery sector. In both sectors the ergonomic factor repeatability was the most prevalent with 80% and 36.4% respectively. In turn, 60% of companies have established snuff redesign making job, compared to 10% presented by jewelery companies, in both sectors finally found a rate not exceeding 13% on completion of training on ergonomic risk control their workers. Conclusions: Ergonomic risk profile ergonomic in the tobacco industry and craft jeweler shows incipient considering be influenced by factors such as ignorance of the subject and lack of management commitment to implement programs to help minimize disease arising from activities taking place in each of the sectors.

Full Text Available The aim of this secondary research is to determine the suitability of social media as an element of marketing communication for craft producers. Secondary research was used to determine the suitability of social media as an element of marketing communication for craft producers in an emerging country. The growth in the craft market is also associated with the rise in local interest in South African craft fuelled by trends towards ethnic, rustic, earthy styles and increasing national pride and the return of local values. The consulted secondary resources confirm that social media has the potential to help crafters to create better brand awareness, better relationships with customers, and increase sales via these mechanisms. However, the major challenge for craft producers to use social media as a communication tool will be limited resources and illiteracy. The research recommends that the South African government provide support in the form of a centralized marketing agency that uses social media to promote craft producers products

Craftwashing in the U.S. Beer Industry

Full Text Available (1 Background: Big brewers, which have experienced declining sales for their beer brands in the last decade, have been accused of “craftwashing” by some craft brewers and their aficionados—they define craftwashing as big brewers (>6 million barrels per year taking advantage of the increasing sales of craft beer by emulating these products or by acquiring craft breweries, while also obscuring their ownership from consumers; (2 Methods: To estimate the prevalence of these practices, the ownership of U.S. mainstream and craft beer brands was decoded and visualized. In addition, an exploratory case study analyzed how these ownership relations are represented in the craft sections of selected retailers (n = 16 in the Lansing, Michigan metropolitan area; (3 Results: By October 2017 in the U.S., all but one big brewer had either acquired a craft brewery, or formed a distribution alliance with one—without disclosing these relationships on the packaging. In the study area, 30% of 4- and 6-pack facings recorded in craft beer sections (n = 1145 had ownership ties to big brewers; (4 Conclusions: Craftwashing is common in the U.S. beer industry, and this suggests consumers must exert substantial effort to become aware of their own role in reinforcing these practices.

Economia criativa e resistência: o artesanato indígena no Estado do Rio de Janeiro

Full Text Available The purpose of this article is to examine the socioeconomic, cultural and political roles of craft to the indigenous population living on authorized indigenous land in Rio de Janeiro and its capital. The central argument suggests that craft has not only the role of income and employment generation in the context of the development of creative economy in the state, but also the resistance to marginalization of indigenous people in public policies and state and federal laws, as well as their invisibility in craftsmen’s social organizations. Craft can lead to greater autonomy and development of indigenous communities by linking aesthetic, symbolic and social elements of local crafts to the improvement of the political and socioeconomic living conditions of communities in the context of the stimulus to creative sectors in areas of the state of Rio de Janeiro. At the same time, craft offers greater visibility to cultural production of marginalized social groups such as indigenous people and brings potentially transformative discussions about their conditions and position in public policies and laws aimed at the craft itself, as well as the craftsmen’s social organizations.

In underwater locomotion, extracting meaningful information from local flows is as desirable as it is challenging, due to complex fluid-structure interaction. Sensing and motion are tightly interconnected; hydrodynamic signals generated by the external stimuli are modified by the self-generated flow signals. Given that very little is known about self-generated signals, we used onboard pressure sensors to measure the pressure profiles over the head of a fusiform-shape craft while moving forward and backward harmonically. From these measurements we obtained a second-order polynomial model which incorporates the velocity and acceleration of the craft to estimate the surface pressure within the swimming range up to one body length/second (L s −1 ). The analysis of the model reveals valuable insights into the temporal and spatial changes of the pressure intensity as a function of craft's velocity. At low swimming velocities ( −1 ) the pressure signals are more sensitive to the acceleration of the craft than its velocity. However, the inertial effects gradually become less important as the velocity increases. The sensors on the front part of the craft are more sensitive to its movements than the sensors on the sides. With respect to the hydrostatic pressure measured in still water, the pressure detected by the foremost sensor reaches values up to 300 Pa at 1 L s −1 swimming velocity, whereas the pressure difference between the foremost sensor and the next one is less than 50 Pa. Our results suggest that distributed pressure sensing can be used in a bimodal sensing strategy. The first mode detects external hydrodynamic events taking place around the craft, which requires minimal sensitivity to the self-motion of the craft. This can be accomplished by moving slowly with a constant velocity and by analyzing the pressure gradient as opposed to absolute pressure recordings. The second mode monitors the self-motion of the craft. It is shown here that distributed

The real-time strategy game StarCraft has proven to be a challenging environment for artificial intelligence techniques, and as a result, current state-of-the-art solutions consist of numerous hand-crafted modules. In this paper, we show how macromanagement decisions in StarCraft can be learned...... directly from game replays using deep learning. Neural networks are trained on 789,571 state-action pairs extracted from 2,005 replays of highly skilled players, achieving top-1 and top-3 error rates of 54.6% and 22.9% in predicting the next build action. By integrating the trained network into UAlberta......Bot, an open source StarCraft bot, the system can significantly outperform the game’s built-in Terran bot, and play competitively against UAlbertaBot with a fixed rush strategy. To our knowledge, this is the first time macromanagement tasks are learned directly from replays in StarCraft. While the best hand...
