    At large attitudes are built on earlier experience with the attitude object. If earlier experiences are not available, as is the case for unfamiliar attitude objects such as new technologies, no stored evaluations exist. Yet, people are still somehow able to construct attitudes on the spot. Depending on the familiarity of the attitude object, attitudes may find their basis more in affect or cognition. The current paper investigates differences in reliance on affect or cognition in attitude formation toward familiar and unfamiliar realistic attitude objects. In addition, individual differences in reliance on affect (high faith in intuition) or cognition (high need for cognition) are taken into account. In an experimental survey among Dutch consumers (N = 1870), we show that, for unfamiliar realistic attitude objects, people rely more on affect than cognition. For familiar attitude objects where both affective and cognitive evaluations are available, high need for cognition leads to more reliance on cognition, and high faith in intuition leads to more reliance on affect, reflecting the influence of individually preferred thinking style. For people with high need for cognition, cognition has a higher influence on overall attitude for both familiar and unfamiliar realistic attitude objects. On the other hand, affect is important for people with high faith in intuition for both familiar and unfamiliar attitude objects and for people with low faith in intuition for unfamiliar attitude objects; this shows that preferred thinking style is less influential for unfamiliar objects. By comparing attitude formation for familiar and unfamiliar realistic attitude objects, this research contributes to understanding situations in which affect or cognition is the better predictor of overall attitudes.

    Object-Oriented Technology (OOT), although not a new paradigm, has recently been prominently featured in the trade press and even general business publications. Indeed, the promises of object technology are alluring: the ability to handle complex design and engineering information through the full manufacturing production life cycle or to manipulate multimedia information, and the ability to improve programmer productivity in creating and maintaining high quality software. Groups at a number of the DOE facilities have been exploring the use of object technology for engineering, business, and other applications. In this white paper, the technology is explored thoroughly and compared with previous means of developing software and storing databases of information. Several specific projects within the DOE Complex are described, and the state of the commercial marketplace is indicated.

  5. Exploring object-oriented technologies

    CERN Document Server

    Ramos Pollan, Raul

    2000-01-01

    Object oriented technologies are the corner stone of modern software development. A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

    2010-11-01

    Older adults (n = 113) participated in focus groups discussing their use of and attitudes about technology in the context of their home, work, and healthcare. Participants reported using a wide variety of technology items, particularly in their homes. Positive attitudes (i.e., likes) outnumbered negative attitudes (i.e., dislikes), suggesting that older adults perceive the benefits of technology use to outweigh the costs of such use. Positive attitudes were most frequently related to how the technology supported activities, enhanced convenience, and contained useful features. Negative attitudes were most frequently associated with technology creating inconveniences, unhelpful features, as well as security and reliability concerns. Given that older adults reported more positive than negative attitudes about the technologies they use, these results contradict stereotypes that older adults are afraid or unwilling to use technology. These findings also highlight the importance of perceived benefits of use and ease of use for models of technology acceptance. Emphasizing the benefits of technology in education and training programs may increase future technology adoption.

  11. Measurement of spatial object's exterior attitude based on linear CCD

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    It is difficult to realize real-time measurement of exterior attitude by the traditional systems based on the area image sensor which have conflict between speed and accuracy.The subsystem for three-dimensional (3D) coordinate rcconstruction of point target (S3DCRPT) which is composed of three one-dimensional (1D) cameras based on linear charge-coupled device (CCD) can determine the distant light spots' spatial position. The attitude angle of the measured object is determined by the spatial solution while the coordinate reconstruction is separately carried on by the S3DCRPT with some point cooperation targets (PCTs) on the measured object. A new optical system is designed to solve the interference problem with one-to-one relationship between the PCTs and the S3DCRPT optical subsystems,which improves the measurement accuracy and saves space. The mathematical model of the attitude measurement is established,and partial and global calibrations are realized for the multi-camera attitude measurement system.The test results show the feasibility of the exterior attitude measurement based on linear CCD.

  16. Use of Hierarchical Mixtures of Experts to Detect Resident Space Object Attitude

    Science.gov (United States)

    Gaylor, D.; Anderson, J.

    2014-09-01

    Space Situational Awareness (SSA) involves detecting, tracking, identifying and characterizing resident space objects (RSOs). Electro-optical measurements can be used to estimate important characteristics, such as the size, shape, configuration, rotational dynamics (attitude and angular velocity), and surface properties such as specular and diffuse albedo (reflectivity) of an RSO. In addition, estimated features can be used to match or discriminate objects or classes of objects and to identify their behavior. Under a Phase I SBIR sponsored by Air Force Research Laboratory (AFRL), Emergent Space Technologies, Inc. investigated the use of Hierarchical Mixtures of Experts (HMEs) to process electro-optical measurements to determine a RSOs attitude profile. This paper discusses the mathematical background of the HME; the assumptions, test scenarios, and results of processing simulated apparent magnitude and angles data including experiments to tune the HME learning rate parameter. The results show that the HME is capable of identifying and distinguishing between nadir-pointing, sun-pointing, and spinning objects even though none of the experts in the HME is directly estimating attitude. This paper also shows how the learning parameter selection impacts HME performance.

  18. Attitude control of an object commonly held by multiple robot arms - A Lyapunov approach

    Science.gov (United States)

    Kreutz, Kenneth; Wen, John T.

    1988-01-01

    Multiple robot arms moving a commonly held object can be viewed as complex actuators whose purpose is to provide net forces and moments to the object. These forces and moments can be used to control the orientation, or attitude, of the object via the Euler equation describing attitude evolution in response to applied moments at the mass center. In contrast to the common approach that feedback-linearizes the attitude dynamics to a double integrator form with respect to some three-parameter local representation of orientation, the authors control the object using a globally nonsingular representation. Using an energy-motivated Liapunov function, globally stable control of attitude is shown.

  3. Reviews of computing technology: Object-oriented technology

    Energy Technology Data Exchange (ETDEWEB)

    Skeen, D.C.

    1993-03-01

    A useful metaphor in introducing object-oriented concepts is the idea of a computer hardware manufacturer assembling products from an existing stock of electronic parts. In this analogy, think of the parts as pieces of computer software and of the finished products as computer applications. Like its counterpart, the object is capable of performing its specific function in a wide variety of different applications. The advantages to assembling hardware using a set of prebuilt parts are obvious. The design process is greatly simplified in this scenario, since the designer needs only to carry the design down to the chip level, rather than to the transistor level. As a result, the designer is free to develop a more reliable and feature rich product. Also, since the component parts are reused in several different products, the parts can be made more robust and subjected to more rigorous testing than would be economically feasible for a part used in only one piece of equipment. Additionally, maintenance on the resulting systems is simplified because of the part-level consistency from one type of equipment to another. The remainder of this document introduces the techniques used to develop objects, the benefits of the technology, outstanding issues that remain with the technology, industry direction for the technology, and the impact that object-oriented technology is likely to have on the organization. While going through this material, the reader will find it useful to remember the parts analogy and to keep in mind that the overall purpose of object-oriented technology is to create software parts and to construct applications using those parts.

  5. Attitudes without objects: evidence for a dispositional attitude, its measurement, and its consequences.

    Hepler, Justin; Albarracín, Dolores

    2013-06-01

    We hypothesized that individuals may differ in the dispositional tendency to have positive vs. negative attitudes, a trait termed the dispositional attitude. Across 4 studies, we developed a 16-item Dispositional Attitude Measure (DAM) and investigated its internal consistency, test-retest reliability, factor structure, convergent validity, discriminant validity, and predictive validity. DAM scores were (a) positively correlated with positive affect traits, curiosity-related traits, and individual preexisting attitudes; (b) negatively correlated with negative affect traits; and (c) uncorrelated with theoretically unrelated traits. Dispositional attitudes also significantly predicted the valence of novel attitudes while controlling for theoretically relevant traits (such as the Big 5 and optimism). The dispositional attitude construct represents a new perspective in which attitudes are not simply a function of the properties of the stimuli under consideration, but are also a function of the properties of the evaluator. We discuss the intriguing implications of dispositional attitudes for many areas of research, including attitude formation, persuasion, and behavior prediction.

  10. Students' Attitudes Toward Gene Technology: Deconstructing a Construct

    Science.gov (United States)

    Gardner, Grant E.; Troelstrup, Angelique

    2015-10-01

    Emergent technologies are commonly characterized as involving cutting-edge developments while lacking wide-scale public implementation. Although currently prevalent in many applications, gene technology is often considered emergent in that the science changes so rapidly. Science educators at all levels of formal education are faced with a unique challenge of facilitating student understanding of gene technology (in comparison with more established content) as well as integrating some of the more controversial socioscientific aspects of such content into the curricula. Much of the literature regarding student understanding of biotechnology has focused on development of student attitudes toward the field and the impact of this on their learning. However, there has, of yet, been no unifying framework in the literature regarding what is meant by attitudes toward gene technology. This article reviews the current scholarship (38 empirical studies published between 1990 and 2011) on the measurement of student attitudes toward biotechnology in order to highlight major themes present within the literature. Items from all reviewed studies were collected, coded, and sorted for construction of a comprehensive instrument representing the conceptualizations of attitudes toward gene technology in all 38 studies. Factor analytic techniques were used as a tool to reduce and categorize measurement items. Results provided a framework of five factors that help describe student attitudes toward biotechnology across all the studies. This emergent framework of factors is proposed as a useful means to standardize the discourse in future research.

    2015-08-01

    In the USA, women have consistently been proportionally underrepresented in science and technology (S&T). In these disciplines, as students move from high schools to colleges to graduate programs, qualified women drop out at higher rates than do men, resulting in a striking loss of talented students. Attitude toward a discipline is one of the major factors in students' choice of majors. As a result, attitudes toward S&T are issues with longstanding attention and interest in education research. Retention of female students in S&T majors remains a major concern. The purpose of the study was to investigate attitudes toward S&T including attitudes toward female participation in S&T, among S&T majors, and examine differences by gender and class standing. Such an investigation would provide deeper insights to help devise strategies to retain women in S&T majors.

    Objective structured clinical examinations (OSCEs) are multistationed clinical examinations that have been shown to be effective in testing students' ability to integrate the knowledge, skills, and attitudes acquired during their preclinical and clinical training and experiences. The original OSCE for the third-year Preventive Dentistry course at Baylor College of Dentistry was based on the traditional format consisting of four sections of twelve stations with a group of twelve students rotating through each of the sections simultaneously. This arrangement allowed for examination of one-half of the class. The other half of the class took the exam on an alternate date. To reduce the disruption caused by the students' moving from station to station and to allow for examination of the entire class in one setting, the traditional concept was modified using computer technology, and the twelve stations "moved" via a PowerPoint presentation while students remained stationary. Questions on both exams provided a means for testing data interpretation, diagnostic skills, and, to some extent, interpersonal skills. The overall atmosphere during the computer-based examination was less chaotic. Each student received identical instructions, explanations, and time allotments to respond to the information presented. The ratio of faculty to students required to monitor the exam was less than required for the traditional format. Additionally, since there was no need to allow time for student transition, the total time required to administer the exam was reduced. Thus, objective assessment of the entire class was accomplished using fewer faculty members and less class time and with less disruption for the students.

    2014-12-01

    Full Text Available This study measured artistically gifted students’ attitudes toward technology and compared them to their math/science peers. Researchers administered the English version of the Modified Fennema Sherman Attitudes Scales (M-FSAS to 149 students enrolled at a residential school (grades 7 – 12 for the artistically and math/science gifted (108 female, 41 male. Analyses revealed no multivariate difference between arts concentrations; however, there was a statistically significant multivariate difference between math/science students and arts students. Further univariate analyses indicated statistically significant differences in all areas except in the gender differences subscale. Math/science students had lower M-FSAS scores, which equate to stronger attitudes surrounding technology. Results suggest that artistically gifted students do not perceive technology as being as relevant to their lives as their math/science gifted peers. For this artistically gifted sample, these results potentially represent fewer career opportunities and creative outlets. Based on these results, educators should imbed into the curriculum opportunities for artistically gifted students to utilize technology for career-oriented purposes. Key Words:

The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

    Objectives: To describe the association of team climate with attitudes toward information and communication technology among nursing staff working on acute psychiatric wards. Background: Implementation of ICT applications in nursing practice brings new operating models to work environments, which may affect experienced team climate on hospital wards. Method: Descriptive survey was used as a study design. Team climate was measured by the Finnish modification of the Team Climate Inventory, and attitudes toward ICT by Burkes' questionnaire. The nursing staff (N = 181, n = 146) on nine acute psychiatric wards participated in the study. Results: It is not self-evident that experienced team climate associates with attitudes toward ICT, but there are some positive relationships between perceived team climate and ICT attitudes. The study showed that nurses' motivation to use ICT had statistically significant connections with experienced team climate, participative safety (p = 0.021), support for innovation (p = 0.042) and task orientation (p = 0.042). Conclusion: The results suggest that asserting team climate and supporting innovative operations may lead to more positive attitudes toward ICT. It is, in particular, possible to influence nurses' motivation to use ICT. More attention should be paid to psychosocial factors such as group education and co-operation at work when ICT applications are implemented in nursing.

    Full Text Available Language education is important in the rapidly changing world. Every year much effort has spent on preparing teaching materials for language education. Since positive attitudes of learners towards a teaching material enhance the effectiveness of that material, it is important to determine the attitudes of learners towards the material used. Learning objects (LOs are a new type of material on which many studies have been conducted in recent years. The aim of this study is to determine the attitudes of students towards LOs in web-based language learning. To this end, the study was conducted in English I Course at the Department of Computer Programming in Kırıkkale University in 2010-2011 Fall Semester. Seventy LOs appropriate for six-week long lecture program were integrated into the Learning Management System (LMS of Kırıkkale University. The study group consisted of 38 students. After the six weeks long implementation period of the study, an attitude scale was administered to the students. The findings indicated that students in web based language education have positive attitudes towards LOs.

    Cultured meat is an unfamiliar emerging food technology that could provide a near endless supply of high quality protein with a relatively small ecological footprint. To understand consumer acceptance of cultured meat, this study investigated the influence of information provision on the explicit and implicit attitude toward cultured meat. Three experiments were conducted using a Solomon four-group design to rule out pretest sensitization effects. The first experiment (N = 190) showed that positive or negative information about cultured meat changed the explicit attitude in the direction of the information. This effect was smaller for participants who were more familiar with cultured meat. In the second experiment (N = 194) positive information was provided about solar panels, an attitude object belonging to the same sustainable product category as sustainable food products such as cultured meat. Positive information about solar panels was found to change the explicit attitude in the direction of the information. Using mood induction, the third experiment (N = 192) ruled out the alternative explanation that explicit attitude change in experiment 1 and 2 was caused by content free affect rather than category based inferences. The implicit attitude appeared insensitive to both information or mood state in all three experiments. These findings show that the explicit attitude toward cultured meat can be influenced by information about the sustainability of cultured meat and information about a positively perceived sustainable product. This effect was shown to be content based rather than merely affect based. Content based information in a relevant context could therefore contribute to the commercial success of cultured meat.

    Values-based studies of people's attitudes towards science and technology not only provide great insights into what drives different attitudes to issues like climate change and genetically modified foods, but allow for segmenting the general public by homogeneous values. Such segmentations both provide better predictions of people's attitudes to new technologies or contentious science issues than age, sex, or other standard demographics, and allow a better matching of different messages with different community values.

    2015-03-01

    Full Text Available Authentication is an important requirement in various applications to restrict the non-legitimate access to certain resources. Radio Frequency Identification (RFID technology helps to perform the authentication task. The detection probability of an object during the authentication process can be increased using multiple number of RFID tags in the object. However, many security risks such as eavesdropping, location privacy etc. are involved in this technology. This paper proposes a secure and lightweight authentication scheme assuming the objects are attached with multiple number of RFID tags. Proper analysis has been carried out to evaluate the security of the proposed scheme, including comparison with a few existing schemes in terms of computation, communication and storage requirements.

    Data mining can effectively obtain the faint spatial object's patterns and characteristics, the universal relations and other implicated data characteristics, the key of which is classifier construction. Faint spatial object classifier construction with spatial data mining technology for faint spatial target detection is proposed based on theoretical analysis of design procedures and guidelines in detail. For the one-sidedness weakness during dealing with the fuzziness and randomness using this method, cloud modal classifier is proposed. Simulating analyzing results indicate that this method can realize classification quickly through feature combination and effectively resolve the one-sidedness weakness problem.

  14. VML 3.0 Reactive Sequencing Objects and Matrix Math Operations for Attitude Profiling

    Science.gov (United States)

    Grasso, Christopher A.; Riedel, Joseph E.

    2012-01-01

    VML (Virtual Machine Language) has been used as the sequencing flight software on over a dozen JPL deep-space missions, most recently flying on GRAIL and JUNO. In conjunction with the NASA SBIR entitled "Reactive Rendezvous and Docking Sequencer", VML version 3.0 has been enhanced to include object-oriented element organization, built-in queuing operations, and sophisticated matrix / vector operations. These improvements allow VML scripts to easily perform much of the work that formerly would have required a great deal of expensive flight software development to realize. Autonomous turning and tracking makes considerable use of new VML features. Profiles generated by flight software are managed using object-oriented VML data constructs executed in discrete time by the VML flight software. VML vector and matrix operations provide the ability to calculate and supply quaternions to the attitude controller flight software which produces torque requests. Using VML-based attitude planning components eliminates flight software development effort, and reduces corresponding costs. In addition, the direct management of the quaternions allows turning and tracking to be tied in with sophisticated high-level VML state machines. These state machines provide autonomous management of spacecraft operations during critical tasks like a hypothetic Mars sample return rendezvous and docking. State machines created for autonomous science observations can also use this sort of attitude planning system, allowing heightened autonomy levels to reduce operations costs. VML state machines cannot be considered merely sequences - they are reactive logic constructs capable of autonomous decision making within a well-defined domain. The state machine approach enabled by VML 3.0 is progressing toward flight capability with a wide array of applicable mission activities.

    2013-11-01

    Current approaches to measuring people's everyday usage of technology-based media and other computer-related activities have proved to be problematic as they use varied outcome measures, fail to measure behavior in a broad range of technology-related domains and do not take into account recently developed types of technology including smartphones. In the present study, a wide variety of items, covering a range of up-to-date technology and media usage behaviors. Sixty-six items concerning technology and media usage, along with 18 additional items assessing attitudes toward technology, were administered to two independent samples of individuals, comprising 942 participants. Factor analyses were used to create 11 usage subscales representing smartphone usage, general social media usage, Internet searching, e-mailing, media sharing, text messaging, video gaming, online friendships, Facebook friendships, phone calling, and watching television in addition to four attitude-based subscales: positive attitudes, negative attitudes, technological anxiety/dependence, and attitudes toward task-switching. All subscales showed strong reliabilities and relationships between the subscales and pre-existing measures of daily media usage and Internet addiction were as predicted. Given the reliability and validity results, the new Media and Technology Usage and Attitudes Scale was suggested as a method of measuring media and technology involvement across a variety of types of research studies either as a single 60-item scale or any subset of the 15 subscales.

    Many early web-based digital libraries (DLs) had implicit assumptions reflected in their architecture that the unit of focus in the DL (frequently "reports" or "e-prints") would only be manifested in a single, or at most a few, common file formats such as PDF or PostScript. DLs have now matured to the point where their contents are commonly no longer simple files. Complex objects in DLs have emerged from in response to various requirements, including: simple aggregation of formats and supporting files, bundling additional information to aid digital preservation, creating opaque digital objects for e-commerce applications, and the incorporation of dynamic services with the traditional data files. We examine a representative (but not necessarily exhaustive) number of current and recent historical web-based complex object technologies and projects that are applicable to DLs: Aurora, Buckets, ComMentor, Cryptolopes, Digibox, Document Management Alliance, FEDORA, Kahn-Wilensky Framework Digital Objects, Metadata Encoding & Transmission Standard, Multivalent Documents, Open eBooks, VERS Encapsulated Objects, and the Warwick Framework.

    2013-07-01

    Survey data on 1217 adults living in Alberta, Canada were collected by Ipsos Reid Public Affairs and made available to us for analysis. The survey questioned participants on issues related to science including their perceived knowledge of science, attitudes toward science, and trust in science and technology. We developed a structural equation model to account for the causal relations implied by the correlations among the variables in the data set. Results show that trust in generalized science and technology is a large determiner of trust in specific technologies, but that trust in specific technologies is not a determinant of overall trust in science and technology. We also found that attitudes towards science have an effect on trust in generalized science and technology whereas perceived knowledge does not. Education and gender contribute to attitudes supporting an increased personal attachment to science, which was the strongest predictor of trust in our model.

However, they encounter statistically significant barriers in the use of the technology. Although some instruments have been developed to measure factors that influence nurses' attitudes towards technology, the validity is questionable and few studies have been developed to test the attitudes of nursing students, in particular. A cross-sectional survey design was performed. The Information Technology Attitude Scales for Health was used to collect data from October 2012-December 2012. A panel of experts reviewed the content of the instrument and a pilot study was conducted. Following this, a total of 508 nursing students, who were engaged in clinical placements, were recruited from six universities in South Korea. Exploratory and confirmatory factor analyses were performed and reliability and construct validity were assessed. The resulting instrument consisted of 19 items across four factors. Reliability of the four factors was acceptable and the validity was supported. The instrument was shown to be both valid and reliable for measuring nursing students' attitudes towards technology, thus aiding in the current understandings of this aspect. Through these measurements and understandings, nursing educators and students are able to be more reflexive of their attitudes and can thus seek to develop them positively. © 2015 John Wiley & Sons Ltd.

    Objectives: This study explores the awareness and the degree of acceptance of the idea of the medical technology cryonics-the freezing of a corpse to revive it in the future-among German citizens. Methods: Data were collected on the basis of a representatively weighted online survey of 1,000 people aged between 16 and 69 years and resident in the Federal Republic of Germany. Results: Forty-seven percent stated that they had already heard of cryonics; 22 percent could imagine having their bodies cryonized after their deaths. For 53 percent, participation in the latest technological developments which correlated with the approval of the conceivability of cryopreservation was important. The majority of the respondents were not skeptical or cautious about innovations in the medical field. Conclusions: The study shows that cryonics is known and accepted to a certain extent. However, a large proportion of respondents did not believe that it was desirable to use medical technology to overcome death, and fundamentally rejected a post-mortal continuation of life.

    Modern theory and research on evaluative processes, combined with a comprehensive review of deliberate self-persuasion (Maio & Thomas, 2007, Pers. Soc. Psychol. Bull., 11, 46), suggest two types of strategies people can use to construct new, more desired attitudes. Epistemic strategies change the perceived valence of associations activated by the attitude object. Teleologic strategies, in contrast, keep undesired associations from being activated in the first place, thus obviating the need to change their perceived valence. Change in perceived valence of associations therefore might predict attitude change better when people pursue epistemic than teleologic strategies for deliberate self-persuasion. This hypothesis gained convergent support from three studies in which use of epistemic versus teleologic strategies was measured as an individual difference (Study 1) and manipulated (studies 2 and 3). The results of these studies supported the theoretical distinction between the two strategies and suggested further research directions. © 2015 The British Psychological Society.

    This document overviews an entirely new approach to determining the composition--the chemical-elemental, isotopic and molecular make-up--of complex, highly structured objects, moreover with microscopic spatial resolution in all 3 dimensions. The front cover depicts the new type of pulsed laser system at the heart of this novel technology under adjustment by Alexis Wynne, and schematically indicates two of its early uses: swiftly analyzing the 3-D composition governed structure of a transistor circuit with both optical and mass-spectrometric detectors, and of fossilized dinosaur and turtle bones high-speed probed by optical detection means. Studying the composition-cued 3-D micro-structures of advanced composite materials and the microscopic scale composition-texture of biological tissues are two near-term examples of the rich spectrum of novel applications enabled by this field-opening analytic tool-set.

    Little is known about Millennial nursing students' attitudes toward computer games and new media in nursing education and whether these attitudes differ between undergraduates and graduates. This study elicited nursing students' experience with computer games and new media, their attitudes toward various instructional styles and methods, and the role of computer games and new media technologies in nursing education. We e-mailed all nursing students enrolled in two universities to invite their participation in an anonymous cross-sectional online survey. The survey collected demographic data and participants' experience with and attitudes toward video gaming and multi-player online health care simulations. We used descriptive statistics and logistic regression to compare the differences between undergraduates and graduates. Two hundred eighteen nursing students participated. Many of the nursing students support using new media technologies in nursing education. Nurse educators should identify areas suitable for new media integration and further evaluate the effectiveness of these technologies.

    This study examines the attitudes of Saudi Arabian high school students toward the use of computer technologies in learning English. The study also discusses the possible barriers that affect and limit the actual usage of computers. Quantitative approach is applied in this research, which involved 30 Saudi Arabia students of a high school in Kuala Lumpur, Malaysia. The respondents comprised 15 males and 15 females with ages between 16 years and 18 years. Two instruments, namely, Scale of Attitude toward Computer Technologies (SACT) and Barriers affecting Students' Attitudes and Use (BSAU) were used to collect data. The Technology Acceptance Model (TAM) of Davis (1989) was utilized. The analysis of the study revealed gender differences in attitudes toward the use of computer technologies in learning English. Female students showed high and positive attitudes towards the use of computer technologies in learning English than males. Both male and female participants demonstrated high and positive perception of Usefulness and perceived Ease of Use of computer technologies in learning English. Three barriers that affected and limited the use of computer technologies in learning English were identified by the participants. These barriers are skill, equipment, and motivation. Among these barriers, skill had the highest effect, whereas motivation showed the least effect.

A questionnaire was prepared by a specialist workgroup to assess the participants' attitude towards the exams. The questionnaire was initially examined in a pilot study. The findings of the questionnaire were used to assess the graduates' attitude towards each examination, as well as to compare the examinations.The OSCE group indicated a significantly more positive attitude compared to the conventional group (p = 0.03. Furthermore, the OSCE group believed the role of theoretical knowledge (p = 0.01 and pre-test practice (p = 0.03 to be significantly greater for success compared to the other group. The structure of OSCE was reported to be superior to conventional examination in terms of fairness and homogeneity (p = 0.004. First participation in exam (p = 0.04 and ultimate success in the exam (p = 0.009 were predictors of graduates' attitude.Based on examinees 'attitudes, OSCE may be a more appropriate choice for graduation examinations of psychiatry compared to the conventional clinical interview examination.

    Full Text Available The use of educational technology (ET worldwide is increasing rapidly, and South Africa is no exception. Grouped amongst the emerging economies of the world, South Africa's information and communication technology (ICT infrastructure is often mentioned as one of the key factors leading to the growth of the country. Integrating ICT into education has become a priority for the South African government. However, it is necessary to move beyond merely providing physical access to ICT's in order for integration to be successful. The integration of ET in schools is greatly influenced by teachers' attitudes towards the technology. The aim of this study was to investigate teachers' attitudes towards educational technology and the factors that are thought to influence teachers' attitudes, namely, perceived usefulness, perceived cultural relevance, perceived competence and access to ET. A convenience sample of 117 teachers in the Johannesburg area, from both public and private schools, across foundation, intermediate and senior phase, completed the Attitudes Towards Computer Scale. Teachers' attitudes were generally positive. The strongest predictor of teachers' attitudes was perceived usefulness followed by perceived cultural relevance. Thus, it is evident that when integrating ET into schools, attention must be paid to teachers perceptions of the utility of ET in order for integration to be successful. Having access to ET and the competence to use ET are not enough for the successful integration of ET in schools.

  17. Delay Kalman Filter to Estimate the Attitude of a Mobile Object with Indoor Magnetic Field Gradients

    Directory of Open Access Journals (Sweden)

    Christophe Combettes

    2016-05-01

    Full Text Available More and more services are based on knowing the location of pedestrians equipped with connected objects (smartphones, smartwatches, etc.. One part of the location estimation process is attitude estimation. Many algorithms have been proposed but they principally target open space areas where the local magnetic field equals the Earth’s field. Unfortunately, this approach is impossible indoors, where the use of magnetometer arrays or magnetic field gradients has been proposed. However, current approaches omit the impact of past state estimates on the current orientation estimate, especially when a reference field is computed over a sliding window. A novel Delay Kalman filter is proposed in this paper to integrate this time correlation: the Delay MAGYQ. Experimental assessment, conducted in a motion lab with a handheld inertial and magnetic mobile unit, shows that the novel filter better estimates the Euler angles of the handheld device with an 11.7° mean error on the yaw angle as compared to 16.4° with a common Additive Extended Kalman filter.

    2017-01-01

    A Commercial Aviation Safety Team (CAST) study of 18 worldwide loss-of-control accidents and incidents determined that the lack of external visual references was associated with a flight crew's loss of attitude awareness or energy state awareness in 17 of these events. Therefore, CAST recommended development and implementation of virtual day-Visual Meteorological Condition (VMC) display systems, such as synthetic vision systems, which can promote flight crew attitude awareness similar to a day-VMC environment. This paper describes the results of a high-fidelity, large transport aircraft simulation experiment that evaluated virtual day-VMC displays and a "background attitude indicator" concept as an aid to pilots in recovery from unusual attitudes. Twelve commercial airline pilots performed multiple unusual attitude recoveries and both quantitative and qualitative dependent measures were collected. Experimental results and future research directions under this CAST initiative and the NASA "Technologies for Airplane State Awareness" research project are described.

It presents the application of this methodology and its ability to evaluate more precisely, both qualitatively and quantitatively, the STS attitudes of students whose overall level is mediocre, since they are outstanding for their lesser adaptation, and their beliefs about science epistemology. It also shows the lack of equivalence between isolated statements used to assess attitudes and their methodological implications for research on attitudes. Finally, it suggests some implications of the results for teaching STS themes in the school.

The purpose of the study is to examine Turkish and American students’ attitudes and thoughts toward the use of educational technologies in history courses, and to compare the results to determine whether there are any differences between the attitudes of Turkish and American student. This study was conducted with 197 American students from Upper Saint Claire High school in Pittsburgh, PA, and 214 Turkish students from Konya High school who volutered for this study. The required data for this study were gathered by a 26-item technology questionnaire, which included 7 multiple-choice questions and 19 Likert scale questions. This questionnaire was developed to gather data on five different areas of interest: (1 demographic information, (2 participants’ computer- and Internet-usage skills, (3 the level of technology used in history classrooms, (4 participants’ attitudes toward technology-enhanced history education, and (5 participants’ attitudes toward history. Most of the Turkish and American students rated themselves as being very well experienced on the eight computer- and Internet-usage skills targeted in this study. But the comparison of the data indicated that American students have higher computer- and Internet-usage skills than Turkish students do, and this difference is statistically significant (p = 0.001. Most of the Turkish and American students showed positive attitudes on using educational technologies in history classrooms. A majority of the Turkish and American students stated that they would be able to focus and learn better if more technological materials were used in classroom activities, and this, in turn, would increase their academic achievements.

  14. Exploring Student Students’ Attitudes and Beliefs Towards E-Portfolios and Technology in Education

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available This article reports on student teachers’ attitude towards technology in education and e-portfolio processes. Attitude is closely related to teachers’ beliefs and the later have been defined as second-order barriers. While an important effort has been made to overcome first-order barrier such as resources, training and support, it cannot be observed that technology has been successfully introduced in education. Therefore, second-order barriers such as attitudes and beliefs are being considered nowadays in order to address the lack of innovative use of technology by teachers. It has been argued that the introduction of technology has to be directed towards the empowerment of cognitive and high-level thinking skills and has to be used based on student-centred approaches. Building e-portfolios and helping students which grow and curate their own Personal Learning Environments (PLE are two approaches to go beyond technology-centered models. E-Portfolios are viewed as part of students’ PLE so social media are used to enhance both e-portfolio processes and students’ PLEs. The research is based on a survey in four groups of students at the local branch in Ibiza of the University of the Balearic Islands. The participants have previously built their e-portfolios with Web 2.0 tools during one semester. Students are asked to document their learning weekly and reflect on the change experienced in the way they think about educational issues. Students are also asked to use new tools and social media services to give evidence of their own learning. The survey is based on a Likert scale so as to be able to analyse the students’ attitude and beliefs towards their e-portfolio and technology in education. The results show that a generally positive attitude is developed by students. Conclusions highlight the slight difference in student teachers’ attitude between technology and specific e-portfolio processes.

    Students' learning interests and attitudes toward science have both been studied for decades. However, the connection between them with students' life experiences about science and technology has not been addressed much. The purpose of this study is to investigate students' learning interests and life experiences about science and technology, and also their attitudes toward technology. A total of 942 urban ninth graders in Taiwan were invited to participate in this study. A Likert scale questionnaire, which was developed from an international project, ROSE, was adapted to collect students' ideas. The results indicated that boys showed higher learning interests in sustainability issues and scientific topics than girls. However, girls recalled more life experiences about science and technology in life than boys. The data also presented high values of Pearson correlation about learning interests and life experiences related to science and technology, and in the perspective on attitudes towards technology. Ways to promote girls' learning interests about science and technology and the implications of teaching and research are discussed as well.

    Bauer, Frank H. (Technical Monitor); Dennehy, Neil; Gambino, Joel; Maynard, Andrew; Brady, T.; Buckley, S.; Zinchuk, J.

    2003-01-01

    The Inertial Stellar Compass (ISC) is a miniature, low power, stellar inertial attitude determination system with an accuracy of better than 0.1 degree (1 sigma) in three axes. The ISC consumes only 3.5 Watts of power and is contained in a 2.5 kg package. With its embedded on-board processor, the ISC provides attitude quaternion information and has Lost-in-Space (LIS) initialization capability. The attitude accuracy and LIS capability are provided by combining a wide field of view Active Pixel Sensor (APS) star camera and Micro- ElectroMechanical System (MEMS) inertial sensor information in an integrated sensor system. The performance and small form factor make the ISC a useful sensor for a wide range of missions. In particular, the ISC represents an enabling, fully integrated, micro-satellite attitude determination system. Other applications include using the ISC as a single sensor solution for attitude determination on medium performance spacecraft and as a bolt on independent safe-hold sensor or coarse acquisition sensor for many other spacecraft. NASA's New Millennium Program (NMP) has selected the ISC technology for a Space Technology 6 (ST6) flight validation experiment scheduled for 2004. NMP missions, such a s ST6, are intended to validate advanced technologies that have not flown in space in order to reduce the risk associated with their infusion into future NASA missions. This paper describes the design, operation, and performance of the ISC and outlines the technology validation plan. A number of mission applications for the ISC technology are highlighted, both for the baseline ST6 ISC configuration and more ambitious applications where ISC hardware and software modifications would be required. These applications demonstrate the wide range of Space and Earth Science missions that would benefit from infusion of the ISC technology.

    Hampf, Daniel; Riede, Wolfgang

    2015-01-01

    In order to avoid collisions with space debris, the near Earth orbit must be continuously scanned by either ground- or spaced-based facilities. For the low Earth orbit, radar telescopes are the workhorse for this task, especially due to their continuous availability. However, optical observation methods can deliver complementary information, especially towards high accuracy measurements. Passive-optical observations are inexpensive and can yield very precise information about the apparent position of the object in the sky via comparison with background stars. However, the object's distance from the observer is not readily accessible, which constitutes a major drawback of this approach for the precise calculation of the orbital elements. Two experimental methods have been devised to overcome this problem: Using two observatories a few kilometres apart, strictly simultaneous observations of the same object yield an accurate, instantaneous 3D position determination through measurement of the parallax. If only on...

  6. A unique fingerprint? Factors influencing attitudes towards science and technology in South Africa

    Directory of Open Access Journals (Sweden)

    Lars Guenther

    2016-07-01

    Full Text Available From an international perspective, research in the field of public attitudes towards science and technology has been conducted since the 1970s. A frequently proposed and empirically supported theory is that strong interest in and knowledge about science in a society is associated with more favourable attitudes towards science. This positive attitude in turn affects support for public funding of science. However, this research field is not without controversy, and for the South African population many questions remain unanswered. Initial research has not explored the factors that shape attitudes towards science and technology in detail. We re-analysed data from the Human Sciences Research Council to explore the above theory. Interestingly, for the South African population, higher levels of scientific literacy and use of information sources are associated with more promises but also more reservations towards science and technology. This is especially true for relatively young and educated survey respondents. In international comparison, South Africa shows a unique fingerprint to some extent, but also shares characteristics with industrially developing countries of Europe (such as Greece or Portugal. To understand the correlations better, future research should aim to examine the overall picture when investigating the diverse South African population more extensively.

The aim of the article is to uncover the attitudes of different generations towards usage of new technologies in purchasing process and determine if the diffusion of innovative purchasing process is significantly different among different generations. The article presents the results of authors´ research of usage of new technologies in purchasing process, as well as attitudes towards it, among different age groups - Generation X, Y, Z and seniors. Results of hybrid research carried out by semi-structured interviews with 551 respondents show, that there are significant generational differences in all three components of attitude towards online purchase, which can be - due to its characteristics- considered the most complex use of new technologies in purchasing process. Results prove that the diffusion of innovation in the purchasing process is significantly influenced by the age group. With age the number of Innovators significantly drops and the percentage of Laggards rises. The ratio of those adopting “early” and “late” significantly changes according to age group as well. Majority of younger respondents are accepting the new technologies into purchasing process early (Innovators, Early Adopters, Early Majority. Middle-aged consumers accept the innovations proportionally - copying the Roger´s curve. Among seniors, the majority is “late” (Late Majority and Laggards.

    Brain–computer–interfaces (BCIs) are important for the next generation of neuro-prosthesis innovations. Only few pilot projects have tested patients’ abilities to control BCIs as well as their satisfaction with the offered technologies. On the one hand, little is known about patients’ moral attitudes toward the benefit-risk-ratio of BCIs as well as their needs, priorities, and expectations. On the other hand, ethics experts intensively discuss the general risks of BCIs as well as the limits of neuro-enhancement. To our knowledge, we present here the first qualitative interview study with ten chronic patients matching the potential user categories for motor and communication BCIs to assess their practical and moral attitudes toward this technology. The interviews reveal practical and moral attitudes toward motor BCIs that can impact future technology development. We discuss our empirical findings on patients’ perspectives and compare them to neuroscientists’ and ethicists’ perspectives. Our analysis indicates only partial overlap between the potential users’ and the experts’ assessments of BCI-technology. It points out the importance of considering the needs and desires of the targeted patient group. Based on our findings, we suggest a multi-fold approach to the development of clinical BCIs, rooted in the participatory technology-development. We conclude that clinical BCI development needs to be explored in a disease-related and culturally sensitive way. PMID:25964745

    Full Text Available In order to investigate the attitude of elite coaches of the team and individual sports towards the role and importance of information technology in sport, 132 coaches were chosen as a sample and answered to the questionnaire of the role of information technology in sport organised by Liebermann and Katz that consisted of 3 different sections: A General attitude of the coaches towards computer and technology; B The importance of science and technology in achieving coaching experience; C Understanding science and technology in sport. Descriptive and inferential statistics (CFA and independent t - test were used in order to analyse the data. The findings demonstrated that elite coaches selected two aims as their chief ones: 1 - Winning medals in competitions; 2- Having a good relationship with the athletes. There was not any significant relationship between the attitudes of the men and women and the coaches of the individual and team sports on science and technology. It seems that elite coaches are aware on the general importance of sport sciences and have a positive attitude towards the use of sport technologies. But they do not practically transfer this positive attitude to competitive sport environments even when they use information technology for other purposes. Eventually it can be stated that the attitude of the coaches towards technology is very positive and consequently it is a must to find strategies in order to encourage them to use current technology and science practically.

    The use of information and communication technology has increased in the society, and can be useful in nursing care. The aim of this study was to describe district nurses' attitudes regarding the implementation of information and communication technology in home nursing. The first and third authors performed five focus group discussions with 19 district nurses' from five primary healthcare centres in northern Sweden. During the focus group discussions, the following topics were discussed: the current and future use of information and communication technology in home nursing; expectations, advantages, disadvantages and hindrances in the use of information and communication technology in home nursing; and the use of information and communication technology from an ethical perspective. The transcribed focus group discussions were analysed using qualitative content analysis. The results showed that district nurses' attitudes were positive regarding the use of information and communication technology in their work. They also asked for possibilities to influence the design and its introduction. However, the use of information and communication technology in home nursing can be described as a complement to communication that could not replace human physical encounters. Improvements and risks, as well as the importance of physical presence in home nursing were considered vital. The results revealed that the use of information and communication technology requires changes in the district nurses' work situation.

  18. Eliciting Public Attitudes Regarding Bioremediation Cleanup Technologies: Lessons Learned from a Consensus Workshop in Idaho

    Energy Technology Data Exchange (ETDEWEB)

    Denise Lach, Principle Investigator; Stephanie Sanford, Co-P.I.

    2003-03-01

    During the summer of 2002, we developed and implemented a ''consensus workshop'' with Idaho citizens to elicit their concerns and issues regarding the use of bioremediation as a cleanup technology for radioactive nuclides and heavy metals at Department of Energy (DOE) sites. The consensus workshop is a derivation of a technology assessment method designed to ensure dialogue between experts and lay people. It has its origins in the United States in the form of ''consensus development conferences'' used by the National Institutes of Health (NIH) to elicit professional knowledge and concerns about new medical treatments. Over the last 25 years, NIH has conducted over 100 consensus development conferences. (Jorgensen 1995). The consensus conference is grounded in the idea that technology assessment and policy needs to be socially negotiated among many different stakeholders and groups rather than narrowly defined by a group of experts. To successfully implement new technology, the public requires access to information that addresses a full complement of issues including understanding the organization proposing the technology. The consensus conference method creates an informed dialogue, making technology understandable to the general public and sets it within perspectives and priorities that may differ radically from those of the expert community. While specific outcomes differ depending on the overall context of a conference, one expected outcome is that citizen panel members develop greater knowledge of the technology during the conference process and, sometimes, the entire panel experiences a change in attitude toward the technology and/or the organization proposing its use (Kluver 1995). The purpose of this research project was to explore the efficacy of the consensus conference model as a way to elicit the input of the general public about bioremediation of radionuclides and heavy metals at Department of Energy sites

  19. From agents to objects: sexist attitudes and neural responses to sexualized targets.

    2011-03-01

    Agency attribution is a hallmark of mind perception; thus, diminished attributions of agency may disrupt social-cognition processes typically elicited by human targets. The current studies examine the effect of perceivers' sexist attitudes on associations of agency with, and neural responses to, images of sexualized and clothed men and women. In Study 1, male (but not female) participants with higher hostile sexism scores more quickly associated sexualized women with first-person action verbs ("handle") and clothed women with third-person action verbs ("handles") than the inverse, as compared to their less sexist peers. In Study 2, hostile sexism correlated negatively with activation of regions associated with mental state attribution-medial prefrontal cortex, posterior cingulate, temporal poles-but only when viewing sexualized women. Heterosexual men best recognized images of sexualized female bodies (but not faces), as compared with other targets' bodies; however, neither face nor body recognition was related to hostile sexism, suggesting that the fMRI findings are not explained by more or less attention to sexualized female targets. Diminished mental state attribution is not unique to targets that people prefer to avoid, as in dehumanization of stigmatized people. The current studies demonstrate that appetitive social targets may elicit a similar response depending on perceivers' attitudes toward them.

    Full Text Available With this study we wanted to test the hypothesis that individual like and dislike as occurring in relation to brand attitude can be objectively assessed. First, individuals rated common brands with respect to subjective preference. Then, they volunteered in an experiment during which their most liked and disliked brand names were visually presented while three different objective measures were taken. Participant's eye blinks as responses to acoustic startle probes were registered with electromyography (EMG (i and their skin conductance (ii and their heart rate (iii were recorded. We found significantly reduced eye blink amplitudes related to liked brand names compared to disliked brand names. This finding suggests that visual perception of liked brand names elicits higher degrees of pleasantness, more positive emotion and approach-oriented motivation than visual perception of disliked brand names. Also, skin conductance and heart rate were both reduced in case of liked versus disliked brand names. We conclude that all our physiological measures highlight emotion-related differences depending on the like and dislike toward individual brands. We suggest that objective measures should be used more frequently to quantify emotion-related aspects of brand attitude. In particular, there might be potential interest to introduce startle reflex modulation to measure emotion-related impact during product development, product design and various further fields relevant to marketing. Our findings are discussed in relation to the idea that self reported measures are most often cognitively polluted.

    With this study we wanted to test the hypothesis that individual like and dislike as occurring in relation to brand attitude can be objectively assessed. First, individuals rated common brands with respect to subjective preference. Then, they volunteered in an experiment during which their most liked and disliked brand names were visually presented while three different objective measures were taken. Participant's eye blinks as responses to acoustic startle probes were registered with electromyography (EMG) (i) and their skin conductance (ii) and their heart rate (iii) were recorded. We found significantly reduced eye blink amplitudes related to liked brand names compared to disliked brand names.

  3. Propellantless Attitude Control of Solar Sail Technology Utilizing Reflective Control Devices

    Munday, Jeremy

    2016-01-01

    Solar sails offer an opportunity for a CubeSatscale, propellant-free spacecraft technology that enables long-term and long-distance missions not possible with traditional methods. Solar sails operate using the transfer of linear momentum from photons of sunlight reflected from the surface of the sail. To propel the spacecraft, no mechanically moving parts, thrusters, or propellant are needed. However, attitude control, or orientation, is still performed using traditional methods involving reaction wheels and propellant ejection, which severely limit mission lifetime. For example, the current state of the art solutions employed by upcoming missions couple solar sails with a state of the art propellant ejection gas system. Here, the use of the gas thruster has limited the lifetime of the mission. To solve the limited mission lifetime problem, the Propellantless Attitude Control of Solar Sail Technology Utilizing Reflective Control Devices project team is working on propellantless attitude control using thin layers of material, an optical film, electrically switchable from transparent to reflective. The technology is based on a polymer-dispersed liquid crystal (PDLC), which allows this switch upon application of a voltage. This technology removes the need for propellant, which reduces weight and cost while improving performance and lifetime.

    As is the case with most developed countries, pressures from various sectors of society have seen computers make a big presence in Australian education systems in the last decade. In the state of Victoria, integrating learning technology (LT) into all key learning areas of every school's curriculum has been a priority policy of governments. Over the last 8-10 years, large amounts of money have been provided to set schools up with computers and associated technologies. In the area of science, a range of LT resources is available for use in the teaching and learning processes in the classroom. However, there has been limited evaluation into teachers' attitudes towards, and types of, methodology and effectiveness of usage of computer-based technologies in knowledge construction. Using both quantitative and qualitative methods, a study aimed at identifying science teachers' opinions and practices with the use of computer-based technologies in their teaching has been carried out in Victorian government schools. The focus of this paper is on the attitudes of these science teachers towards the use of computer-based technologies in their teaching. The study showed that most teachers have embraced the introduction of these technologies into the school structure well and are generally positive about their potential in the classroom. However, their use in the classrooms is infrequent and often on an ad hoc basis. A range of obstacles preventing the use of these technologies are identified and discussed in this paper.

    The aim of this study was to better understand nurses' and other staff members' attitudes toward the usefulness of information and communication technology in home-care settings. Research has found that beliefs about the expected benefits of information and communication technology impact the use of technology. Furthermore, inexperience with using information and communication technology may cause negative attitudes. This article is based on a questionnaire to 155 nurses and other staff members in home-care in Sogn og Fjordane county in Norway. The results revealed minimal use of information and communication technology at work; however, participants had positive attitudes regarding the potential benefits of information and communication technology use in home-care. Individuals' extensive use of and familiarity with different solutions in private lives could be an important context for explaining employees' attitudes. Given that information and communication technology is both a welfare service and a market good, this may explain individuals' positive attitudes toward information and communication technology despite their lack of experience with it at work. Experiences with information and communication technology as a market good and the way new technologies can affect work routines will affect the implementation of information and communication technology in home-care.

  8. The use of software agents and distributed objects to integrate enterprises: Compatible or competing technologies?

    Energy Technology Data Exchange (ETDEWEB)

    Pancerella, C.M.

    1998-04-01

    Distributed object and software agent technologies are two integration methods for connecting enterprises. The two technologies have overlapping goals--interoperability and architectural support for integrating software components--though to date little or no integration of the two technologies has been made at the enterprise level. The primary difference between these two technologies is that distributed object technologies focus on the problems inherent in connecting distributed heterogeneous systems whereas software agent technologies focus on the problems involved with coordination and knowledge exchange across domain boundaries. This paper addresses the integration of these technologies in support of enterprise integration across organizational and geographic boundaries. The authors discuss enterprise integration issues, review their experiences with both technologies, and make recommendations for future work. Neither technology is a panacea. Good software engineering techniques must be applied to integrate an enterprise because scalability and a distributed software development team are realities.

  10. Design of relative motion and attitude profiles for three-dimensional resident space object imaging with a laser rangefinder

    Science.gov (United States)

    Nayak, M.; Beck, J.; Udrea, B.

    This paper focuses on the aerospace application of a single beam laser rangefinder (LRF) for 3D imaging, shape detection, and reconstruction in the context of a space-based space situational awareness (SSA) mission scenario. The primary limitation to 3D imaging from LRF point clouds is the one-dimensional nature of the single beam measurements. A method that combines relative orbital motion and scanning attitude motion to generate point clouds has been developed and the design and characterization of multiple relative motion and attitude maneuver profiles are presented. The target resident space object (RSO) has the shape of a generic telecommunications satellite. The shape and attitude of the RSO are unknown to the chaser satellite however, it is assumed that the RSO is un-cooperative and has fixed inertial pointing. All sensors in the metrology chain are assumed ideal. A previous study by the authors used pure Keplerian motion to perform a similar 3D imaging mission at an asteroid. A new baseline for proximity operations maneuvers for LRF scanning, based on a waypoint adaptation of the Hill-Clohessy-Wiltshire (HCW) equations is examined. Propellant expenditure for each waypoint profile is discussed and combinations of relative motion and attitude maneuvers that minimize the propellant used to achieve a minimum required point cloud density are studied. Both LRF strike-point coverage and point cloud density are maximized; the capability for 3D shape registration and reconstruction from point clouds generated with a single beam LRF without catalog comparison is proven. Next, a method of using edge detection algorithms to process a point cloud into a 3D modeled image containing reconstructed shapes is presented. Weighted accuracy of edge reconstruction with respect to the true model is used to calculate a qualitative “ metric” that evaluates effectiveness of coverage. Both edge recognition algorithms and the metric are independent of point cloud densit

    Studies in K-12 and college students show that their learning preferences have been strongly shaped by new media technologies like video games, virtual reality environments, the Internet, and social networks. However, there is no known research on medical students' game experiences or attitudes towards new media technologies in medical education. This investigation seeks to elucidate medical student experiences and attitudes, to see whether they warrant the development of new media teaching methods in medicine. Medical students from two American universities participated. An anonymous, 30-item, cross-sectional survey addressed demographics, game play experience and attitudes on using new media technologies in medical education. Statistical analysis identified: 1) demographic characteristics; 2) differences between the two universities; 3) how video game play differs across gender, age, degree program and familiarity with computers; and 4) characteristics of students who play most frequently. 217 medical students participated. About half were female (53%). Respondents liked the idea of using technology to enhance healthcare education (98%), felt that education should make better use of new media technologies (96%), and believed that video games can have educational value (80%). A majority (77%) would use a multiplayer online healthcare simulation on their own time, provided that it helped them to accomplish an important goal. Men and women agreed that they were most inclined to use multiplayer simulations if they were fun (97%), and if they helped to develop skill in patient interactions (90%). However, there was significant gender dissonance over types of favorite games, the educational value of video games, and the desire to participate in games that realistically replicated the experience of clinical practice.

    The aim of the present study was to assess self-reported oral health habits, attitudes, lifestyle between the sample groups of preclinical and clinical dental and technology students in Lithuania using the Hiroshima University Dental Behavioral Inventory (HU-DBI), and to evaluate the impact of education on their behavior and self-reported oral health. A sample of 183 dental and 75 technology students at the Lithuanian University of Health Sciences, Medical Academy, Faculty of Odontology, and Kaunas University of Technology completed the Lithuanian version the HU-DBI questionnaire with 11 additional items. The data were analyzed using the "SPSS 19.0 for Windows" software package. The mean HU-DBI score of clinical final-year dentistry students was significantly higher (p=0.001) than the score of the preclinical group (6.81 (1.2) and 5.96 (1.5), respectively). The mean scores of both groups of dental students were significantly (p<0.05) higher than that of the technology group (5.37 (1.8)). Oral health behaviors and knowledge were superior in dental students. Dental education had a significant positive impact on the oral health and behavior improvement. The attitudes of the Lithuanian dental students should be further improved by initiating a comprehensive program that would emphasize the importance of oral hygiene before the clinical program starts.

    Full Text Available This study used a cross-sectional survey design to examine the relationship between the attitudes of seventh to twelfth-grade social studies teachers and their perceptions of the competency needed toward implementing technology into their classrooms. Also, it investigated the extent to which the combination of teaching experience, grade-level taught and gender, predict teachers’ attitudes toward implementing technology into their classrooms. Furthermore, this study explored the extent to which the combination of teachers’ attitude, teaching experience, grade level taught and gender predict teachers’ perceptions of the competency needed toward implementing technology into their classroom. The convenience sample of Jordanian social studies teachers (n = 221 was a blend of male (n = 135 and female teachers (n = 86. The result s showed that teachers with relatively high positive attitudes toward implementing technology were far more likely to have high perceptions of competency needed for implementing technology in social studies classrooms. The results also showed that the combination of teaching experience, grade-level taught, and gender variables were a statistically significant predictor of attitudes. Meanwhile, the combination of teaching experience, grade-level taught, gender, and attitude variables predicted about eighty percent of teachers’ perceptions of competency scores, which is extremely high.

    Many obstacles need to be overcome if digital and electronic technologies are to be fully integrated in the operation of dental clinics in some countries. These obstacles may be physical, technical, or psychosocial barriers in the form of perceptions and attitudes related to software incompatibilities, patient privacy, and interference with the patient-practitioner relationship. The objectives of the study are to assess the perceptions of Indian dental students of one school toward the usefulness of digital technologies in improving dental practice; their willingness to use digital and electronic technologies; the perceived obstacles to the use of digital and electronic technologies in dental care setups; and their attitudes toward Internet privacy issues. The study population consisted of 186 final year undergraduate dental students from the A. B. Shetty Memorial institute of Dental Sciences, Rajiv Gandhi University of Health Sciences, Mangalore, India. Survey data were analyzed descriptively . Most students indicated that information technology enhances patient satisfaction, the quality of dental record, diagnosis, treatment planning, and doctor-doctor communication. Cost of equipment and need for technical training were regarded as major obstacles by substantial proportions of respondents. Most dental students at our school feel that the information technology will support their decision making in diagnoses and devising effective treatment plans, which in turn increase patient satisfaction and quality of care. Students also perceived that lack of technical knowledge and the high cost of implementation are major barriers to developing information technology in India.

    Deducting the future switching of the road transport energy technology is one of the key preconditions for relative technology development planning. However,one of the difficulties is to address the issue of multi-objective and conflicting constrains, e.g., minimizing the climate mitigation or minimizing economic cost. In this paper, a dynamic optimization model was established, which can be used to analyze the road transport energy technology switching under multi-objective constrains.Through one case study, a series of solutions could be derived to provide decision-makers with the flexibility to choose the appropriate solution with respect to the given situation.

    An illusory sensation of ownership over a surrogate limb or whole body can be induced through specific forms of multisensory stimulation, such as synchronous visuotactile tapping on the hidden real and visible rubber hand in the rubber hand illusion. Such methods have been used to induce ownership over a manikin and a virtual body that substitute the real body, as seen from first-person perspective, through a head-mounted display. However, the perceptual and behavioral consequences of such transformed body ownership have hardly been explored. In Exp. 1, immersive virtual reality was used to embody 30 adults as a 4-y-old child (condition C), and as an adult body scaled to the same height as the child (condition A), experienced from the first-person perspective, and with virtual and real body movements synchronized. The result was a strong body-ownership illusion equally for C and A. Moreover there was an overestimation of the sizes of objects compared with a nonembodied baseline, which was significantly greater for C compared with A. An implicit association test showed that C resulted in significantly faster reaction times for the classification of self with child-like compared with adult-like attributes. Exp. 2 with an additional 16 participants extinguished the ownership illusion by using visuomotor asynchrony, with all else equal. The size-estimation and implicit association test differences between C and A were also extinguished. We conclude that there are perceptual and probably behavioral correlates of body-ownership illusions that occur as a function of the type of body in which embodiment occurs.

Health professional educators need to be responsive to health professionals' information and communication technological needs; however, there is a paucity of information about educators' attitudes to, and capabilities with, ICT. Methods: Fifty-two health professional educators, enrolled in health professional education postgraduate studies, participated in an online subject with specific eLearning components requiring the use of ICT. They completed a pre- and postquestionnaire pertaining to ICT attitudes, confidence, and usage. Results: Participants reported significant increases in overall ICT confidence during the subject despite it being high at baseline (mean: 7.0 out of 10; P=0.02. Even with increased ICT confidence, there were decreases in the participants' sense of ICT control when related to health professional education (P=0.002; whereas, the amount of time participants engaged with ICT devices was negatively correlated with the sense of ICT control (P=0.002. The effect of age and health discipline on ICT attitudes and confidence was not significant (P>0.05. Conclusion: This study reports that health professional educators have perceptual deficits toward ICT. The impact of eLearning increased confidence in ICT but caused a reduction in participants' sense of control of ICT. Health professional educators require more ICT training and support to facilitate better ICT integration in health professional education settings. Keywords: confidence, sense of control

    The FASTSAT-HSV01 spacecraft is a microsatellite with magnetic torque rods as it sole attitude control actuator. FASTSAT s multiple payloads and mission functions require the Attitude Control System (ACS) to maintain Local Vertical Local Horizontal (LVLH)-referenced attitudes without spin-stabilization, while the pointing errors for some attitudes be significantly smaller than the previous best-demonstrated for this type of control system. The mission requires the ACS to hold multiple stable, unstable, and non-equilibrium attitudes, as well as eject a 3U CubeSat from an onboard P-POD and recover from the ensuing tumble. This paper describes the Attitude Control System, the reasons for design choices, how the ACS integrates with the rest of the spacecraft, and gives recommendations for potential future applications of the work.

    Approximately half of individuals living with type 2 diabetes mellitus (T2DM) have suboptimal self-management, which could be improved by using assistive technologies in self-management regimes. This study examines patient attitudes and intentions to adopt assistive technologies into T2DM self-management. Forty-four participants (M = 58.7 years) with T2DM were recruited from diabetes education classes in the southwestern Ontario, Canada, between February and April 2014. Participants completed a self-reported in-person survey assessing demographic characteristics, current diabetes management, and attitudes toward using assistive technologies in their diabetes self-management. Demographics, disease characteristics, and current technology use and preferences of the cohort were examined, followed by a correlational analysis of descriptive characteristics and attitudes and intentions to use technology in self-management. The majority of (but not all) participants felt that using Internet applications (65%) and smartphone (53.5%) applications for self-management was a good idea. The majority of participants did not currently use an Internet (92.5%) or mobile (96%) application for self-management. Of participants, 77% intended to use an Internet application to manage their diabetes in the future and 58% intended to use mobile applications. Younger age was associated with more positive attitudes (r = -.432, P = .003) and intentions (r = -.425, P = .005) to use assistive technologies in diabetes self-management. Findings suggest that patients, especially those younger in age, are favorable toward adopting assistive technologies into management practice. However, attitudes among older adults are less positive, and few currently make use of such technologies in any age group. © 2014 Diabetes Technology Society.

    Novel food technologies, such as cloning, have been introduced into the meat production sector; however, their use is not widely supported by many consumers. This study was designed to assess whether Japanese consumers' attitudes toward consumption of cloned beef (specifically, beef derived from bovine embryo and somatic cell-cloned cattle) would change after they were provided with technological information on animal cloning through a web-based survey. The results revealed that most respondents did not discriminate between their attitudes toward the consumption of the two types of cloned beef, and that most respondents did not change their attitudes toward cloned beef after receiving the technological information. The respondents' individual characteristics, including their knowledge about the food safety of cloned beef and their basic knowledge about animal cloning, influenced the likelihood of a change in their attitudes after they received the information. In conclusion, some consumers might become less uncomfortable about the consumption of cloned beef by the straightforward provision of technological information about animal cloning; however, most consumers are likely to maintain their attitudes.

    Full Text Available Lucie Cerna, Petra Maresova Department of Economics, Faculty of Informatics and Management, University of Hradec Kralove, Hradec Kralove, Czech Republic Background: The incidence of diabetes is rising across the world. This global problem significantly affects the economic and social development in the 21st century. If the disease is diagnosed in time, the number of complications as well as the costs of therapy will be lower. Modern technologies permeate all spheres of medicine, and diabetes treatment is no exception. Therefore, the aim of this article is to analyze patients’ attitudes to the use of modern technologies in the treatment of diabetes (type 1 diabetes mellitus [T1DM] and type 2 diabetes mellitus [T2DM].Methods: A total of 313 respondents from the Czech Republic in the period from June 24, 2015, to July 24, 2015, participated in a questionnaire survey. The target group was diabetics regardless of the type of illness. Collected data were analyzed using descriptive statistical methods, Z-test, and test of independence (Pearson’s chi-squared test.Results: Although in other areas mobile applications are used to monitor patients’ health condition in ~30% of cases, in the case of diabetes they are used by only 4% of respondents. Approximately 8% of participants use an application, but they do not like it. The rest of the respondents have never used any mobile application. These low figures are due to a lack of knowledge about the availability and possibilities of mobile applications. A positive correlation was proven between technical skills and methods of entering data. Gender and age show only a weak dependency of the method of writing data on their own health condition. Furthermore, the monitored parameters show that patients with T1DM control and know more about their health condition than patients with T2DM, which is reflected, for example, by more frequent blood glucose measurements or larger track of their physical activity

    Researches on Augmented Reality (AR) have recently received attention. With these, the Machine-to-Machine (M2M) market has started to be active and there are numerous efforts to apply this to real life in all sectors of society. To date, the M2M market has applied the existing marker-based AR technology in entertainment, business and other industries. With the existing marker-based AR technology, a designated object can only be loaded on the screen from one marker and a marker has to be added to load on the screen the same object again. This situation creates a problem where the relevant marker'should be extracted and printed in screen so that loading of the multiple objects is enabled. However, since the distance between markers will not be measured in the process of detecting and copying markers, the markers can be overlapped and thus the objects would not be augmented. To solve this problem, a circle having the longest radius needs to be created from a focal point of a marker to be copied, so that no object is copied within the confines of the circle. In this paper, software-based sensing technology for multiple object detection and loading using PPHT has been developed and overlapping marker control according to multiple object control has been studied using the Bresenham and Mean Shift algorithms.

    Morgan and colleagues put forth a call to action for the transformation of the Canadian healthcare system through the adoption of a national chronic disease prevention and management (CDPM) strategy. They offer examples of best practices and national solutions including investment in clinical information technologies to help support improved care and outcomes. Although we acknowledge that the authors propose CDPM solutions that are headed in the right direction, more rapid deployment of solutions that harness the potential of advanced collaborative technologies is required. We provide examples of how technologies that exist today can help to accelerate the achievement of some key CDPM objectives.

    Educational technologies have had an important role in respiratory care. Distance learning via postal correspondence has been used extensively in respiratory care, and Internet-based distance learning is now used in the training of respiratory therapists (RTs), clinical continuing education, and in baccalaureate degree and higher programs for RTs and educators. To describe the current scope of respiratory care educational technology integration, including distance learning. To investigate online research potential in respiratory care. A probabilistic online survey of United States respiratory care program directors was conducted on educational technology practices and attitudes, including distance learning. A parallel exploratory study of United States respiratory care managers was conducted. One-hundred seventy-seven (53%) program directors participated. One-hundred twenty-eight respiratory care managers participated. For instructional purposes, the respiratory care programs heavily use office-productivity software, the Internet, e-mail, and commercial respiratory care content-based computer-based instruction. The programs use, or would use, online resources provided by text publishers, but there is a paucity. Many program directors reported that their faculty use personal digital assistants (PDAs), often in instructional roles. 74.6% of the programs offer no fully online courses, but 61.0% reported at least one course delivered partially online. The managers considered continuing education via online technologies appropriate, but one third reported that they have not/will not hire RTs trained via distance learning. Neither group considered fully online courses a good match for RT training, nor did they consider training via distance learning of comparable quality to on-campus programs. Both groups rated baccalaureate and higher degrees via distance learning higher if the program included face-to-face instruction. Online distance-learning participatory experience

    Background: Periodic general health examinations (GHEs) are gradually becoming more popular as they employ subclinical screenings, as a means of early detection. This study considers the effect of information technology (IT), health communications and the public's attitude towards GHEs in Vietnam. Methods: A total of 2,068 valid observations were obtained from a survey in Hanoi and its surrounding areas. Results: In total, 42.12% of participants stated that they were willing to use IT applications to recognise illness symptoms, and nearly 2/3 of them rated the healthcare quality at average level or below. Discussion: The data, which was processed by the BCL model, showed that IT applications (apps) reduce hesitation toward GHEs; however, older people seem to have less confidence in using these apps. Health communications and government's subsidy also increased the likelihood of people attending periodic GHEs. The probability of early check-ups where there is a cash subsidy could reach approximately 80%.

  2. A multi-objective stochastic approach to combinatorial technology space exploration

    Science.gov (United States)

    Patel, Chirag B.

    Historically, aerospace development programs have frequently been marked by performance shortfalls, cost growth, and schedule slippage. New technologies included in systems are considered to be one of the major sources of this programmatic risk. Decisions regarding the choice of technologies to include in a design are therefore crucial for a successful development program. This problem of technology selection is a challenging exercise in multi-objective decision making. The complexity of this selection problem is compounded by the geometric growth of the combinatorial space with the number of technologies being considered and the uncertainties inherent in the knowledge of the technological attributes. These problems are not typically addressed in the selection methods employed in common practice. Consequently, a method is desired to aid the selection of technologies for complex systems design with consideration of the combinatorial complexity, multi-dimensionality, and the presence of uncertainties. Several categories of techniques are explored to address the shortcomings of current approaches and to realize the goal of an efficient and effective combinatorial technology space exploration method. For the multi-objective decision making, a posteriori preference articulation is implemented. To realize this, a stochastic algorithm for Pareto optimization is formulated based on the concepts of SPEA2. Techniques to address the uncertain nature of technology impact on the system are also examined. Monte Carlo simulations using the surrogate models are used for uncertainty quantification. The concepts of graph theory are used for modeling and analyzing compatibility constraints among technologies and assessing their impact on the technology combinatorial space. The overall decision making approach is enabled by the application of an uncertainty quantification technique under the framework of an efficient probabilistic Pareto optimization algorithm. As a result, multiple

    When comparing the features of points in 3-dimensional point cloud recognition process, spatial attitude transform must be taken into account due to different attitudes of point cloud, but the old algorithm of spatial attitude is of high complexity and of high computation cost. To deal with the above issues, we propose an attitude correction algorithm for similar objects. It chooses three groups of non-collinear corresponding points at the position the two similar objects are to be identified, through space transformation and rotation it unifies the attitudes of similar parts to set up the base for objects recognition. The feasibility and validity of the algorithm are proved by the correction using point cloud model of the car.%在三维点云识别过程中,由于点云姿态不同,比较点的特征时,要将空间姿态变换计算在内,旧的空间姿态算法复杂度高,计算量大.针对上述问题,提出一种相似物体的姿态矫正算法,通过在两个相似物体要进行识别的位置上选择不共线的三组对应点,经过空间变换与旋转,将相似部位的姿态统一,为物体识别做基础.通过使用汽车点云模型进行矫正,验证了该算法的可行性和正确性.

    Background Older adults are at substantial risk for cardiovascular disorders that may require anticoagulation therapy. Those on warfarin therapy report dissatisfaction and reduced quality of life (QOL) resulting from the treatment. Advances in the area of mobile health (mHealth) technology have resulted in the design and development of new patient-centric models for the provision of personalized health care services to improve care delivery. However, there is a paucity of research examining the effectiveness of mHealth tools on knowledge, attitudes, and patient satisfaction with treatment, as well as self-management, adherence to therapy, and QOL in older adults with chronic illness conditions requiring long-term warfarin therapy. Objective The objective of the study was to explore the attitudes and preferences of older adults on warfarin therapy regarding the use of mHealth technology and health games to gain skills for self-management. Methods We conducted group and individual interviews with patients (60 years or older) on warfarin therapy at two anticoagulation clinics affiliated with an academic medical center. We held 4 group and 2 individual interviews, resulting in 11 patient participants and 2 family caregiver participants. We used structured questions on three topic areas including medication self-management strategies, mHealth technology use, and health games for exercise. We demonstrated some commercial health apps related to medication management, vitamin K content of food, and a videogame for balance exercise. Discussions were audiotaped and transcribed verbatim. Common themes were drawn using content analysis. Results The participants reported awareness of the importance of staying on schedule with warfarin therapy. They also acknowledged that negative experiences of friends or family members who were taking warfarin influenced their desire to keep on schedule with warfarin therapy. In addition, the participants expressed that the use of m

    The question of how ready the public is for the implementation of large-scale programs of technological change is considered. Four vital aspects of the issue are discussed which include: (1) the ways in which the public mis-perceives the change process, (2) the ways in which recent history impacts on public attitudes, (3) the ways in which the public divides among itself, and (4) the fundamentals of public attitudes towards change. It is concluded that nothing is so critical in the 1970's to securing public approval for large-scale planned change projects as is securing the approval by change-agents of the public.

    Full Text Available Problem statement: Despite various initiatives and programmes by the government to incorporate ICT in education, not much research has been done to evaluate the achievement of these initiatives and programmes, including ICT proficiency among students. This study fills in the gap of lack of current information pertaining to the Malaysian secondary school students’ ICT competencies, knowledge on internet and attitudes toward computer technology. Approach: Data for this study has been gathered from a survey on 585 students in Sekolah Menengah Kebangsaan Tengku Temenggung Ahmad (SMKTTA in the rural district of Kundang Ulu, Johore. The specific area has been selected by Universiti Kebangsaan Malaysia under one of its community service projects.The instrument used was a questionnaire comprised of demographic variables and three other sub-scales. The sub-scales are software and hardware usage; motivation for self study and ICT usage competency and Internet usage and safety awareness. Results: Results show that generally, students have moderately positive attitudes toward ICT, have low to moderate level of ICT competencies and have limited knowledge on internet. Conclusion: Findings from this study have implications to the approach of teaching and learning of ICT subjects, their evaluation and assessment and future initiative related to ICT education and infrastructure development towards creating a well-connected society. It is recommended that schools provide enough facilities for students’ hands-on experiences. Teachers should incorporate productive computing activities in their teaching such as using spreadsheet, database and programming, besides purposive web searching. Rural internet centres should also be established. Evaluation, monitoring and maintainance of ICT programs is a must to ensure their effectiveness and efficiency. The utmost end result would be the emergence of more ICT proficient personnel who will contribute to the development

    Background The incidence of diabetes is rising across the world. This global problem significantly affects the economic and social development in the 21st century. If the disease is diagnosed in time, the number of complications as well as the costs of therapy will be lower. Modern technologies permeate all spheres of medicine, and diabetes treatment is no exception. Therefore, the aim of this article is to analyze patients’ attitudes to the use of modern technologies in the treatment of diabetes (type 1 diabetes mellitus [T1DM] and type 2 diabetes mellitus [T2DM]). Methods A total of 313 respondents from the Czech Republic in the period from June 24, 2015, to July 24, 2015, participated in a questionnaire survey. The target group was diabetics regardless of the type of illness. Collected data were analyzed using descriptive statistical methods, Z-test, and test of independence (Pearson’s chi-squared test). Results Although in other areas mobile applications are used to monitor patients’ health condition in ~30% of cases, in the case of diabetes they are used by only 4% of respondents. Approximately 8% of participants use an application, but they do not like it. The rest of the respondents have never used any mobile application. These low figures are due to a lack of knowledge about the availability and possibilities of mobile applications. A positive correlation was proven between technical skills and methods of entering data. Gender and age show only a weak dependency of the method of writing data on their own health condition. Furthermore, the monitored parameters show that patients with T1DM control and know more about their health condition than patients with T2DM, which is reflected, for example, by more frequent blood glucose measurements or larger track of their physical activity. Conversely, the relationship between the associated complications and self-care activities has not been demonstrated. Conclusion Despite the current fast development of

    2017-01-01

    Based on data from a survey (n = 3291) and 14 qualitative interviews among Danish older adults, this study investigated the use of, and attitudes toward, information communications technology (ICT) and the digital delivery of public services. While age, gender, and socioeconomic status were associated with use of ICT, these determinants lost their explanatory power when we controlled for attitudes and experiences. We identified three segments that differed in their use of ICT and attitudes toward digital service delivery. As nonuse of ICT often results from the lack of willingness to use it rather than from material or cognitive deficiencies, policy measures for bridging the digital divide should focus on skills and confidence rather than on access or ability.

    The purpose of this paper is to explore the attitudes of nursing home administrators and key managerial staff toward health information technology (health IT). This research is exploratory in nature, and applies qualitative case-study methodology to further understand health IT adoption by nursing homes through multiple in-depth semi-structured interviews of management, and direct observations of employee behavior at each participating facility. A modified Technology Acceptance Model is used to examine the attitudes and perceptions of administrators. This study finds that there are differences in the level of health IT adoption by nursing homes. While some administrators are aware of health IT and are implementing or updating their IT systems in a gradual but haphazard manner, others exhibited a lack of interest in implementing change. Overall, there is a lack of systematic planning and decision-making toward health IT adoption. Adoption is not evidence-based, instead driven primarily by real and perceived regulatory requirements combined with a lack of information about, or consideration of, the real costs and benefits of implementing health IT. Including six in-depth case studies, the sample for this study is small for generalizing the findings. Yet, it contributes to the literature on the slow process of health IT adoption by nursing homes. Moreover, the findings provide guidelines for future research. This study demonstrates that nursing home administrators must systematically plan the adoption of health IT, and such decision making should be evidenced-based and participatory so that employees can voice their opinions that could prevent future resistance. This study is original and advances knowledge on the reasons for the slow adoption of health IT in nursing homes. It finds that lack of adequate information regarding the utility and benefits of health IT in management adoption decisions can result in haphazard implementation or no adoption at all. This

    The smartphone has emerged as an important technological device to assist physicians with medical decision making, clinical tasks, and other computing functions. A smartphone is a device that combines mobile telecommunication with Internet accessibility as well as word processing. Moreover, smartphones have additional features such as applications pertinent to clinical medicine and practice management. The purpose of this study was to investigate the innovation factors that affect a physician's decision to adopt an emerging mobile technological device such as a smartphone. The study sample consisted of 103 physicians from community hospitals and academic medical centers in the southeastern United States. Innovation factors are elements that affect an individual's attitude toward using and adopting an emerging technology. In our model, the innovation characteristics of compatibility, job relevance, the internal environment, observability, personal experience, and the external environment were all significant predictors of attitude toward using a smartphone. These influential innovation factors presumably are salient predictors of a physician's attitude toward using a smartphone to assist with clinical tasks. Health information technology devices such as smartphones offer promise as a means to improve clinical efficiency, medical quality, and care coordination and possibly reduce healthcare costs.

    Nurses are exposed to the changing demands in technology as they execute their patient-related duties in the workplace. Integration of Information Technology (IT) in healthcare systems improves the quality of care provided. Nursing students with prior exposure to computers tend to have a positive influence IT. A descriptive study design using a quantitative approach and structured questionnaire was used to measure the nurses' attitudes towards computer usage. A census of 45 post-basic first year nursing management students were participated in this study. The students demonstrated a positive attitude towards the use of a computer. But access to and use of a computer and IT was limited and nurses in clinics had no access to IT. A lack of computer skills was identified as a factor that hinders access to IT. Nursing students agreed that computer literacy should be included in the curriculum to allow them to become independent computer users. The Department of Health should have IT in all health-care facilities and also train all health-care workers to use IT. With the positive attitudes expressed by the students, nurse managers need to create a conducive environment to ensure such a positive attitude continues to excel. © 2011 Blackwell Publishing Ltd.

    Full Text Available The strategic planning means the future planning of an organization; in other words, it refers to the direction that the organization wants to move in that direction. Strategic planning of the information technology for any organization is an evidence that the organization’s information architecture in light of strategic considerations such as mission, objectives, and priorities of the organization becomes evident and it determines the necessary administration plan to achieve systems and forms the informational databases at the organizational level. To put differently, strategic planning of the information technology charter and the macro program in the field of information systems are generally considered as the information technology. Different approaches are used for planning. Now, the dominant approach for developing the long-term program or for ICT master plan of information technology is an approach of the organizational architecture or the information technology architecture. The purpose of this research is a preliminary introduction with an organizational architecture approach with the means of strategic planning of the information systems.

    The purpose of this study is to determine attitudes of doctors of chiropractic regarding the importance of staff training in specific skill areas to inform the curriculum management process of a chiropractic technology program. A survey was distributed to registrants of a chiropractic homecoming event. On a 5-point Likert scale, respondents were asked to rate the degree of importance that staff members be trained in specific skills. Descriptive statistics were derived, and a 1-way analysis of variance (ANOVA) was used to test differences between groups based on years in practice and level of staff training. Doctors place a high level of importance on oral communication skills and low importance on nutrition and physical examinations. Comparing groups based on years in practice revealed differences in the areas of passive physiotherapies (F = 3.61, p = .015), legal issues/regulations (F = 3.01, p = .032), occupational safety and health regulation (F = 4.27, p = .006), and marketing (F = 2.67, p = .049). Comparing groups based on level of staff training revealed differences in the areas of occupational safety and health regulations (F = 4.56, p = .005) and cardiopulmonary resuscitation (F = 4.91, p = .003). With regard to their assistants, doctors of chiropractic tend to place high importance on office skills requiring effective communication and place less importance on clinical skills such as physical examinations and physiotherapy.

    Background Gender preference is prevalent in some communities and using medical techniques to choose the baby's sex may cause the gender discrimination and gender imbalance in communities. Therefore, evaluating the gender preferences and attitudes towards using sex selection technologies seems to be necessary. Methods This cross-sectional study was conducted in Avicenna Fertility Center. Participants were 100 women with one child who were referred for sex selection. Data were collected through self-developed questionnaires. The questions were designed by the researchers at the experts’ panel. To determine the validity of the questionnaire, the viewpoints of professors specialized in these issues were obtained. The statistical analysis of the data was performed using SPSS software (Version 11.5), and p < 0.05 was considered significant. Results Tendency toward the male was more than female sex (55.5% male, 15.5% female and 28.5% no tendency). Majority of participants agreed with sex selection with medical reason and sex selection in order to balance the family. Women's level of education had positive effect on agreements to fetal sex selection with medical and non-medical reasons (p < 0.001). Conclusion Although gender preferences were toward the male sex but this preference was not very strong. Most participants agreed with non-medical sex selection for balancing the sex composition of their children. It doesn't seem that non-medical sex selection for family balancing causes severe sex imbalance in Iran. PMID:25717434

    Full Text Available Innovation activities, as well as innovations, are closely related meanings, and like many others economical definitions, have a broad range of meanings. Main characteristics and attributes of innovation involves new or significantly improved product, that’s being used, or in other words, found its application, and innovative activities – activities focused on realization of innovations. In this article, innovations are mainly considered in terms of high-technology production, evidence from Russian space industry. There are 5 basic stages of lifecycle of innovative project in considered industry: initiation, development, realization, expansion, consumption. Practically, third or fourth, or even both of these stages, often missing because there is no need of them. R&D activities, or even further serial production, based on previous developments, is an innovation activity, because these activities are stages of innovative projects lifecycle itself. Then it seems legit, to draw a conclusion, that in terms of high-technology production, company’s primary activity equals innovative activity. Basic characteristics of innovative activity of high-technology companies as assessment and forecasting object involves high level of uncertainty at every stage of projects lifecycle, high dependency on funding level of this activity, and high level and erratic structure of risk. All the above mentioned, means that assessment and forecasting of innovative activity of high-technology companies, needs development of its own methodological tools for each industry.

    Shih, Ann T.; Ancel, Ersin; Jones, Sharon M.

    2012-01-01

    The concern for reducing aviation safety risk is rising as the National Airspace System in the United States transforms to the Next Generation Air Transportation System (NextGen). The NASA Aviation Safety Program is committed to developing an effective aviation safety technology portfolio to meet the challenges of this transformation and to mitigate relevant safety risks. The paper focuses on the reasoning of selecting Object-Oriented Bayesian Networks (OOBN) as the technique and commercial software for the accident modeling and portfolio assessment. To illustrate the benefits of OOBN in a large and complex aviation accident model, the in-flight Loss-of-Control Accident Framework (LOCAF) constructed as an influence diagram is presented. An OOBN approach not only simplifies construction and maintenance of complex causal networks for the modelers, but also offers a well-organized hierarchical network that is easier for decision makers to exploit the model examining the effectiveness of risk mitigation strategies through technology insertions.

    We present a 220 GHz 3D imaging `Pathfinder' radar developed within the EU FP7 project CONSORTIS (Concealed Object Stand-Off Real-Time Imaging for Security) which has been built to address two objectives: (i) to de-risk the radar hardware development and (ii) to enable the collection of phenomenology data with ~1 cm3 volumetric resolution. The radar combines a DDS-based chirp generator and self-mixing multiplier technology to achieve a 30 GHz bandwidth chirp with such high linearity that the raw point response is close to ideal and only requires minor nonlinearity compensation. The single transceiver is focused with a 30 cm lens mounted on a gimbal to acquire 3D volumetric images of static test targets and materials.

  5. Fetal subjects and maternal objects: reproductive technology and the new fetal/maternal relation.

    Science.gov (United States)

    Squier, S

    1996-10-01

    This essay examines three tendencies nurtured in the practices of reproductive technology - tendencies with profoundly disturbing implications for us as individuals and as social beings. They are: 1) the increasing subjectification of the fetus (that is, the increasing tendency to posit a fetal subject), 2) the increasing objectification of the gestating woman, leading to her representation as interchangeable object rather than unique subject, and 3) the increasing tendency to conceive of the fetus and the mother as social, medical, and legal antagonists. Considering the construction of fetus, mother, and the fetal/maternal relation in earlier (Western) historical periods, a contemporary work of literature, a government report, and the popular press, I argue that as the fetus is increasingly being understood as a subject, the mother is increasingly being reduced to an antagonist, an obstacle to fetal health, and an object. The essay concludes by offering some tentative conclusions about the general process of fetal subjectification in the United States and Europe.

    The aim of the study was to assess differences in attitudes towards aspects of assisted reproduction technology between infertile and parous women. Case-control study. University-based tertiary care clinic. Three hundred and ninety-two women with fertility problems and 200 parous controls. A questionnaire was sent out to 392 the members of Childless Support Association and 200 parous women who had at least three infants and had given birth at Kuopio University Hospital. The questionnaire consisted of 46 questions: demographic information, fertility history, different aspects of assisted reproduction technology and prioritisation issues. Attitudes towards assisted reproduction technology. The overall response rate was 46%. Infertile women were highly educated (P 2 or surrogate mothers (30.6% vs 15.2%) and limitations in the number of infertility treatment cycles (28.4% vs 61.4%). For 11 questions, we recorded minor, but statistically significant, differences. In the prioritisation questions, the women set the order according to their own interests, probably because the women were at fertile age and they had or would like to have a child. Maternity services and screening for cancer in women (Papanicolaou's test and mammography) were at the top of the list. These results reflect a split attitude that was influenced by the wish of infertile women to help childless couples and to be able to recruit suitable sperm/oocyte donors. Parous women were motivated by their concern for children's rights.

Control is based on the propositions of the fourth modified invariance form with the use of bootstrapping methods. The paper presents analysis of results obtained by two different correction methods. The essence of the first method lies in injection of additional component into the already established control signal and formation of the channel for that component. Control signal correction during the signal synthesis stage in the control device constitutes the basis for the second method. Research results have shown high efficiency of application for both correction methods. Both methods have roughly the same precision. We have shown that the correction in the control device is preferable because it has no influence on the inner contour of the system. We have shown the necessity of the block usage with the variable transmission coefficient, which value is determined by technological trajectory parameters. Research results can be applied in practice for improvement of the precision specifications of automatic control systems for trajectorial manipulators.

    In Korea, the well-integrated research of biological effects of radiation has been launched from the late 1960s. As research activities, the following food items have been dealt with: sprouting foods, fruits, mushrooms, grains, spices or mixed condiments, fish or fishery products, meat or meat products, and fermented foods. The usage of gamma radiation from [sup 60]Co source is now authorized for food irradiation of the following items: potato, onion, garlic, chestnut, mushroom, dried mushroom, dried spices (including red pepper, garlic, black pepper, onion, ginger, and green onion), dried meat, powdered fish and shellfish, soybean paste powder, hot pepper paste powder, soybean sauce powder, and starch. Since the authorization of food irradiation in 1985, consumers' acceptance has been considered the most important. The survey evaluating the basic perception and attitule toward food irradiation revealed the following results. Consumers' awareness of food irradiation was 82%, with significantly higher in radiation workers than the general public (p<0.0001). Seventy-five percent distinguished the contaminated food by radionuclides from irradiated food. In purchasing irradiated foods, 50.9% required more information. The contribution of irradiated foods to wholesomeness was suspicious in 51%, acceptable in 33%, and uncertain in 16%. If information about the benefits of irradiation is provided to consumers, positive response was increased to 60%. The most critical impediment in the commercial application of food irradiation was found to have resulted from the general consumers' slow acceptance; however, consumers' attitude to irradiated food became positive if they understood the safety and advantages of this technology. The most important task is to overcome consumers' psychological resistance and transporting matters of the products to be irradiated. (N.K.).

  12. DETERMINING THE TEACHERS’ VIEWS ON THE APPLICABILITY OF THE TECHNOLOGY DESIGN OBJECTIVES IN 9th GRADE PHYSICS CURRICULUM

    Full Text Available Recently, as technological developments have been increasing, people need to have more knowledge and learn the ways of acquisition of knowledge. To follow the technological developments requires being a scientifically literate person (Kortland, 2010. Because of this reason, new reforms are put into practice in all areas as well as in science education. And scientific literacy has become a major aim of science education. Scientific literacy is defined as the capacity to use scientific knowledge, to identify questions and to draw evidence-based conclusions in order to understand and help make decisions about the natural world and the changes made to it through human activity. Scientific literacy is a major aim in science education but which approach could be effective at developing scientific literacy? Science educators developed context-based approach to integrate scientific knowledge and real life events, and the designed their After the curriculum changes in many countries, Turkey has also changed the physics curriculum. In schools, physics books which are based on context-based approach are being used as reference books. The reasons of changing teaching curriculums may be ‘the failure to make students scientifically literate’, ‘a weak link between science/physics and daily life’, ‘a negative image of the subject such as difficulty and requirement of mathematics’, and ‘a decrease in students’ motivation around high content overload’. Context-based approach aims to develop and sustain a sense of wonder and curiosity in young people about the natural world. At the same time, a context can make students connect scientific knowledge to real life (Colburn, 2000; Saka, 2006. The students are required to induce meanings by using contexts, thus justifying a ‘need-to-know’ approach to content. Thus, students’ interest and positive attitudes towards physics have been increased (Campbell vd., 2000; Bennett ve Lubben, 2006; Bultev

    The objective of this study was to develop new scales measuring knowledge and attitude about UVR and sun related behavior, and to examine their association to sun related behavior objectively measured by personal dosimetry. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week that measured their UVR exposure. Afterwards, they answered a questionnaire on sun-related items. We applied descriptive analysis, linear and logistic regression analysis to evaluate the associations between the questionnaire scales and objective UVR measures. Perceiving protection as routine and important were positively correlated with protective behavior. Knowledge deficit of UV and risk of melanoma, perceived benefits and importance of protection behavior was also correlated with use of protection. ‘Knowledge deficit of UV and risk of melanoma and Perceived barrier towards sun avoidance between 12 and 15’ were both associated with increased risk of sunburn. Attitude towards tan was associated to both outdoor time and exposure as well as use of protection, but not to sunburn. The results regarding Knowledge deficit of UV and risk of melanoma associated to UVR exposure and Perceived barrier towards sun avoidance between 12 and 15 emphasize the importance of awareness of melanoma risk and the priority of the skin cancer prevention advice. Shifting activities to outside the suns peak-hours could be an approach for structural and campaign preventive measures. Knowledge of items predicting exposure to UVR, use of protection and sunburn are important for planning of preventive interventions and melanoma research. PMID:28542543

    Fusion is an essentially inexhaustible source of energy that has the potential for economically attractive commercial applications with excellent safety and environmental characteristics. The primary focus for the fusion-energy development program is the generation of centralstation electricity. Fusion has the potential, however, for many other applications. The fact that a large fraction of the energy released in a DT fusion reaction is carried by high-energy neutrons suggests potentially unique applications. These include breeding of fissile fuels, production of hydrogen and other chemical products, transmutation or “burning” of various nuclear or chemical wastes, radiation processing of materials, production of radioisotopes, food preservation, medical diagnosis and medical treatment, and space power and space propulsion. In addition, fusion R&D will lead to new products and new markets. Each fusion application must meet certain standards of economic and safety and environmental attractiveness. For this reason, economics on the one hand, and safety and environment and licensing on the other hand, are the two primary criteria for setting long-range commercial fusion objectives. A major function of systems analysis is to evaluate the potential of fusion against these objectives and to help guide the fusion R&D program toward practical applications. The transfer of fusion technology and skills from the national laboratories and universities to industry is the key to achieving the long-range objective of commercial fusion applications.

    Gender differences in choice of studies emerge already in adolescence. Two studies with adolescents are presented, the goal of which is to explore the influence of gender by assessing males and females who choose studies related to Medicine or Engineering. Study 1, correlational (N = 330, mean age 15.9, 56.7% girls), shows that girls who choose technology are more poorly appraised than girls who choose other studies. Study 2 (N = 130; mean age 16.77, 56.2% girls), experimental, measures implicit attitudes (using the IAT) towards males and females from Medicine and Engineering. Implicit attitudes are more favorable towards women if they are studying Medicine and towards men if they study Engineering. The results are analyzed with relation to the percentages of boys and girls in the different fields of study.

    The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine the feasibility of utilizing widespread current consumer-based technology to assist in distributing appropriate videos for objective evaluation. Videos from residents were recorded via a direct connection from the camera processor via an S-video output via a cable into a hub to connect to a standard laptop computer via a universal serial bus (USB) port. A standard consumer-based video editing program was utilized to capture the video and record in appropriate format. We utilized mp4 format, and depending on the size of the file, the videos were scaled down (compressed), their format changed (using a standard video editing program), or sliced into multiple videos. Standard available consumer-based programs were utilized to convert the video into a more appropriate format for handheld personal digital assistants. In addition, the videos were uploaded to a social networking website and video sharing websites. Recorded cases of laparoscopic cholecystectomy in a porcine model were utilized. Compression was required for all formats. All formats were accessed from home computers, work computers, and iPhones without difficulty. Qualitative analyses by four surgeons demonstrated appropriate quality to grade for these formats. Our preliminary results show promise that, utilizing consumer-based technology, videos can be easily distributed to surgeons to grade via GOALS via various methods. Easy accessibility may help make evaluation of resident videos less complicated and cumbersome.

  20. Automated Micro-Object Detection for Mobile Diagnostics Using Lens-Free Imaging Technology

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Lens-free imaging technology has been extensively used recently for microparticle and biological cell analysis because of its high throughput, low cost, and simple and compact arrangement. However, this technology still lacks a dedicated and automated detection system. In this paper, we describe a custom-developed automated micro-object detection method for a lens-free imaging system. In our previous work (Roy et al., we developed a lens-free imaging system using low-cost components. This system was used to generate and capture the diffraction patterns of micro-objects and a global threshold was used to locate the diffraction patterns. In this work we used the same setup to develop an improved automated detection and analysis algorithm based on adaptive threshold and clustering of signals. For this purpose images from the lens-free system were then used to understand the features and characteristics of the diffraction patterns of several types of samples. On the basis of this information, we custom-developed an automated algorithm for the lens-free imaging system. Next, all the lens-free images were processed using this custom-developed automated algorithm. The performance of this approach was evaluated by comparing the counting results with standard optical microscope results. We evaluated the counting results for polystyrene microbeads, red blood cells, and HepG2, HeLa, and MCF7 cells. The comparison shows good agreement between the systems, with a correlation coefficient of 0.91 and linearity slope of 0.877. We also evaluated the automated size profiles of the microparticle samples. This Wi-Fi-enabled lens-free imaging system, along with the dedicated software, possesses great potential for telemedicine applications in resource-limited settings.

    There is an increasing demand for high-resolution recording of in situ underwater cultural heritage. Reflectance transformation imaging (RTI) has a proven track record in terrestrial contexts for acquiring high-resolution diagnostic data at small scales. The research presented here documents the first adaptation of RTI protocols to the subaquatic environment, with a scuba-deployable method designed around affordable off-the-shelf technologies. Underwater RTI (URTI) was used to capture detail from historic shipwrecks in both the Solent and the western Mediterranean. Results show that URTI can capture submillimeter levels of qualitative diagnostic detail from in situ archaeological material. In addition, this paper presents the results of experiments to explore the impact of turbidity on URTI. For this purpose, a prototype fixed-lighting semisubmersible RTI photography dome was constructed to allow collection of data under controlled conditions. The signal-to-noise data generated reveals that the RGB channels of underwater digital images captured in progressive turbidity degraded faster than URTI object geometry calculated from them. URTI is shown to be capable of providing analytically useful object-level detail in conditions that would render ordinary underwater photography of limited use.

METHODS: All of the second class students of the year 2006-2007 of MTVTS were included (N=161 in the study, response rate was 92%. The survey questionare included questions on knowledge, the risk perception and attitute about GMOs. The legal framework in Turkey about GMOs, the rationale for GMO production, the labeling for GMO and the students’ perception of their knowledge was evaluated through 14 items with Likert scale. After the questionaire, the students received an informative brochure on GMOs. RESULTS: The open-ended question asking to define GMOs was answered by 59,2% of the students among which 35,6% defined as “additive”, 34,5% as “food with hormones”. The risk perceived for GMOs was the forth following cigarette smoking, stres, and environmental pollution in the ranking according to the risk score means. Sex has been the only determinant effecting this scoring for GMOs where girls perceived the risk greater. If family was one of the information sources about GMOs, the perceived risk was increased (p=0,000. Among the students 81,6% thought that GMO should not be grown in Turkey, 77,7% think that GMO was sold however. The leading topic of ambivalence is the state of self knowledge on GMO. The low income group are less concerned about consuming GMO for themselves or for their children (respectively p==0.003 ve p=0,012. CONCLUSION: Health workers are assigned with an important role to inform the public for healthy eating. However although the the risk perception of the study group for GMOs is high, their knowledge is low. Training activities to supply this deficiency should be implemented.

    Many modern technological advances have direct impact on the format, style and efficacy of delivery and consumption of educational content. For example, various novel communication and information technology tools and resources enable efficient, timely, interactive and graphical demonstrations of diverse scientific concepts. In this manuscript, we report on a meta-study of 3 controlled experiments of using the Statistics Online Computational Resources in probability and statistics courses. Web-accessible SOCR applets, demonstrations, simulations and virtual experiments were used in different courses as treatment and compared to matched control classes utilizing traditional pedagogical approaches. Qualitative and quantitative data we collected for all courses included Felder-Silverman-Soloman index of learning styles, background assessment, pre and post surveys of attitude towards the subject, end-point satisfaction survey, and varieties of quiz, laboratory and test scores. Our findings indicate that students' learning styles and attitudes towards a discipline may be important confounds of their final quantitative performance. The observed positive effects of integrating information technology with established pedagogical techniques may be valid across disciplines within the broader spectrum courses in the science education curriculum. The two critical components of improving science education via blended instruction include instructor training, and development of appropriate activities, simulations and interactive resources.

    2013-10-01

    A recurring objection to the exploration, development and deployment of radical new technologies is based on their implications with regards to social justice. In this article, using synthetic biology as an example, I explore this line of objection and how we ought to think about justice in the context of the development and introduction of radically new technologies. I argue that contrary to popular opinion, justice rarely provides a reason not to investigate, develop and introduce radical new technologies, although it may have significant implications for how they ought to be introduced. In particular I focus on the time dependency of justice objections and argue that often these function by looking only at the implications of the introduction of the technology at the point of introduction, rather than the more important long-term impact on patterns of distribution and opportunity.

    This study examined the attitudes of children with typical development towards an unfamiliar peer with complex communication needs using augmentative and alternative communication (AAC) systems. Specifically, the study aimed to compare attitudes when the peer used mobile technology (i.e., iPad(©)(1) ) with an AAC-specific application (Proloquo2Go™ (2) ) versus a low-technology communication board. A within-group crossover design was utilized involving 78 children. Half of the participants (i.e., Group 1) viewed Video 1 of an unfamiliar peer with complex communication needs in a scripted communication interaction using an iPad with Proloquo2Go followed by Video 2 of the same interaction using a communication board. The other half of the participants (Group 2) viewed these videos in the reverse sequence. The Communication Aid/Device Attitudinal Questionnaire (CADAQ) was completed after watching each video. Results indicated that both groups were more positive towards Video 1 (iPad with Prologuo2Go) on certain dimensions of the CADAQ. The results are discussed and recommendations for future research provided.

    The use of mHealth technology is an innovative approach for screening low-income mothers for depression. Past studies show that the use of technology removes barriers such as literacy issues, language challenges, concerns about privacy and lack of transportation and can also increase reliability. However, little is known about staff attitudes and perceptions towards using mHealth technology for screening low-income women for depression in clinics. Four focus groups were conducted with staff members in a supplemental nutrition program for women, infants and children located in a public health clinic. A semi-structured focus group interview guide was used to examine staff perceptions related to depression screening with tablet technology. All interviews were audio recorded and transcribed verbatim. Thematic analysis was used to analyse all focus group data. Three major benefits and two major barriers were found. The benefits of using technology for perinatal depression screenings were reduction of literacy and language barriers, reduction of redundancy and errors and increased privacy for clients. The barriers were increased network issues and responsibility for technology, which included fear of the devices being lost, stolen or broken. Before implementing mHealth tablet technology for depression screening in a public health clinic, it is important to address the concerns of staff members to make the transition more effective. This study provides timely information on staff-perceived benefits and barriers when implementing mHealth technology in a public health setting. © The Author 2014.

    This report examines the public perception of Carbon Capture and Storage technology and the impacts of information on perception. We analyze, from an electronic questionnaire with technical and contextual information, dimensions such as the initial reaction to the technology, the acceptance of CO{sub 2} storage, the perception of risk of storage and the degree of antagonism toward the organizations involved. The determinants of attitudes and reactions to CCS are also analyzed. A favorable initial reaction to CCS is found after some information and contextualization of CCS as well as significant risk perception. The type of information transmitted appears to influence the attitude of participants to the technology. The broader positive impact on attitude occurs when transmitting the idea of CO{sub 2} as a natural resource. (Author) 4 refs.

    研究了论坛客观性如何影响看帖者对帖子所推荐产品的态度,及其影响的内在机制和边界条件.结果表明:当论坛不客观时,看帖者对产品的态度较差,当论坛比较客观时,看帖者对产品的态度较好;说服知识在此过程中起中介作用;品牌强度、看帖者过去对品牌的满意度、跟帖者与楼主的熟悉程度会调节论坛客观性对看帖者态度的影响,当品牌强度相对较弱、看帖者过去对品牌相对不满意、跟帖者与楼主不熟悉或跟帖者与楼主的意见不完全一致时,论坛客观性显著影响看帖者的态度.%The anonymity of the Internet, the difficulty of identifying shills, and the large number of Internet users make it worthwhile to explore the influence of the forum objectivity on WOM recipients' attitudes, the boundaryconditions of the influence, and the underlying mechanism. Based on the research on objectivity of individuals as information sources (Williams et al., 2004), objectivity of forums is defined as consumers' overall opinion of the objectivity of all threads in the forum.Four studies were conducted. With 140 Internet surfers participanting in study 1, we employed a 2 (objectivity of forums: objective versus not) × 2 (brand strength: strong versus weak) between-subjects design. In the "objective" condition, participants were told Haizhu wanted to buy an MP4, and he or she saw a thread on the exact MP4 in a large forum which he or she usually surf. Participants were also told that Haizhu usually saw some followers pointed out the initiator was a shill on the forum in the "not objective" condition. We describe the strong brand as one of the famous brands with high reputaion and the relatively weak brand as a not famous brand. All the participants saw the same thread recommending the MP4. The following three studies are similar to study 1. With 78 Internet surfers participating in study 2, we employed a 2 (objectivity of forums) x 2

  2. Assessment of secondary student attitudes and achievement in marine science using ArcViewRTM GIS technology

    Healy, Genevieve F.

    This multi-disciplinary study explored the cognitive and pedagogical implications of integrating ArcViewRTM GIS technology into secondary science classrooms. Two middle and high school earth/environmental science teachers implemented an 8-week marine science unit into their curriculum by following an experimental design that incorporated two different instructional methods. Four hundred seven (407) students were introduced to marine science concepts using ArcViewRTM GIS technology and traditional methods of teaching at different times during implementation and then tested to identify significant effects on students' performance of content skills, cognitive skills, and spatial skills. Data were collected via the administration of pre-, mid-, and post-implementations of a 50-question multiple choice test and a 38-question attitude survey. The results of the repeated measures ANOVA analyses suggested that both teacher and condition showed statistically significant effects on middle school student performance of content, cognition, and spatial skills, but only the effect of teacher showed significance on high school student performance. Although condition showed significance in middle school performance, the similarities between condition patterns for both middle and high school groups suggested there was not enough convincing evidence to prove that either ArcViewRTM GIS or traditional instructional methods had any effect on middle or high school students' content, cognition or spatial skills. Attitude survey data indicated that high school group attitudes may have some relationship to shifts in content scores; again however, there was no convincing evidence that suggested that middle or high school student attitudes improved as a result of ArcViewRTM GIS implementation. Lack of implementation procedures, attrition rate and pre-existing group differences contributed to weaknesses in the validity of the study. The implications of this study include contributions to

    确定独特的研究对象、构建完整的理论体系、发展专门的研究方法是学科独立、成熟的三大标志。为论证教育技术学的独立性和成熟性,在研究了教育技术学的完整理论体系和专门研究方法两个标志的基础之上,本文首先分别运用历史方法和逻辑方法多层次解析了教育技术学的研究对象;然后,根据确定研究对象的抽象概括原则,将教育技术学的研究对象抽象概括为:教育的技术化和系统化。%Determining its unique research objects, Constructing a complete theoretical system, and developing special-ized research methods are three characteristics of an independent and mature field. Among these three objects, the re-search object is the most fundamental. A clear understanding of research objects helps to avoid the research blind are-as, set up the complete theoretical system of subjects, and develop specialized research methods. To determine the re-search object is also beneficial to the division of human research field and cooperation in research activities To determine the independence and maturity of Educational Technology, this paper uses historical and logical methods to analyze the research objects in the field of educational technology based on a study of its theoretical system and research methods. The historical method is to analyze the research content in the history of a subject, then to abstract and general-ize. The logical method is to toanalyze the attribute and the nature of a subject, then to abstract and generalize. Using historical method to analyze the research objects of Educational Technology,we can abstract out four as-pects of the research object application of visual media in education, First, from the four stages of development of for-eign educational technology, application of audio-visual media in education, the design and use of messages which control the learning process, the design, development, utilization

    Students in both nurse and teacher training are now expected to learn to make effective use of IT for their profession. However, they enter training with a variety of experience in IT which will affect how they respond to further IT skills training. In this survey, 154 nursing and 128 teacher training students reported on the uses they had made of computers and their attitudes towards them. Also, as a sense of being in control of the computer is important for becoming involved in its use, they completed a questionnaire to locate their locus of internal control. The teacher training students were more likely than the nursing students to have access to a home computer, to use computers more often and to have used a greater variety of software. However, this may be a gender effect as a greater proportion of the teacher trainees were male. For both teacher training and nursing students, having a more internal locus of control was correlated with more positive attitudes towards computers. This finding is important for those introducing students to the use of IT in their professions, so that appropriate software and teaching styles involving less open-ended tasks may be provided for the less internally controlled individuals. Interestingly, a much stronger relationship between being more internally controlled and being less scared of using a computer was found for teacher trainees than for nurse trainees. Thus for nurse trainees it is more likely that there are other individual factors predisposing them to fear using computers.

  10. Modeling nurses' attitude toward using automated unit-based medication storage and distribution systems: an extension of the technology acceptance model.

    Science.gov (United States)

    Escobar-Rodríguez, Tomás; Romero-Alonso, María Mercedes

    2013-05-01

    This article analyzes the attitude of nurses toward the use of automated unit-based medication storage and distribution systems and identifies influencing factors. Understanding these factors provides an opportunity to explore actions that might be taken to boost adoption by potential users. The theoretical grounding for this research is the Technology Acceptance Model. The Technology Acceptance Model specifies the causal relationships between perceived usefulness, perceived ease of use, attitude toward using, and actual usage behavior. The research model has six constructs, and nine hypotheses were generated from connections between these six constructs. These constructs include perceived risks, experience level, and training. The findings indicate that these three external variables are related to the perceived ease of use and perceived usefulness of automated unit-based medication storage and distribution systems, and therefore, they have a significant influence on attitude toward the use of these systems.

More than 70% of responders worked in public or academic libraries.Subjects – Librarians and library staff at mostly public and academic libraries.Methods – The study was conducted during a two week period in April 2006 through an online questionnaire that was sent to library and librarian‐related electronic mail lists. The questionnaire was divided into two parts and contained a total of 39 questions. Part one contained eight questions that asked for demographic data and the respondent’s daily attitude toward the adoption of information and communication technologies. Questions regarding age, number of years worked in a library, career, type of library environment worked in, and primary responsibilities within that environment were asked. For one question the respondents were asked to identify which of the categories they fall under when adopting a new technology. The results from part one were used to consider the innovativeness of librarians. The results from part two were used for a study of opinions on innovations and their relative advantage. Main Results – A total of 1,417 responses were received. Of those, 1,128 were fully completed and considered valid and used for inquiry. The majority of respondents worked in public or academic libraries. Nine hundred and twenty‐six respondents, or 88%, were from the U.S. and represented more than 300 distinct zip codes. Two hundred and two respondents, or 12%, were international respondents.This study notes that the sociologist, Everett Rogers, identified and defined five adopter categories in 1958. Those categories are: innovators, early adapters, early majority, late majority, and laggards. The

    Barak, Moshe; Asad, Khaled

    2012-04-01

    Background : This research focused on the development, implementation and evaluation of a course on image-processing principles aimed at middle-school students. Purpose : The overarching purpose of the study was that of integrating the learning of subjects in science, technology, engineering and mathematics (STEM), and linking the learning of these subjects to the children's world and to the digital culture characterizing society today. Sample : The participants were 60 junior high-school students (9th grade). Design and method : Data collection included observations in the classes, administering an attitude questionnaire before and after the course, giving an achievement exam and analyzing the students' final projects. Results and conclusions : The findings indicated that boys' and girls' achievements were similar throughout the course, and all managed to handle the mathematical knowledge without any particular difficulties. Learners' motivation to engage in the subject was high in the project-based learning part of the course in which they dealt, for instance, with editing their own pictures and experimenting with a facial recognition method. However, the students were less interested in learning the theory at the beginning of the course. The course increased the girls', more than the boys', interest in learning scientific-technological subjects in school, and the gender gap in this regard was bridged.

  18. Internet of Things based on smart objects technology, middleware and applications

    CERN Document Server

    Trunfio, Paolo

    2014-01-01

    The Internet of Things (IoT) usually refers to a world-wide network of interconnected heterogeneous objects (sensors, actuators, smart devices, smart objects, RFID, embedded computers, etc) uniquely addressable, based on standard communication protocols. Beyond such a definition, it is emerging a new definition of IoT seen as a loosely coupled, decentralized system of cooperating smart objects (SOs). A SO is an autonomous, physical digital object augmented with sensing/actuating, processing, storing, and networking capabilities. SOs are able to sense/actuate, store, and interpret information created within themselves and around the neighbouring external world where they are situated, act on their own, cooperate with each other, and exchange information with other kinds of electronic devices and human users. However, such SO-oriented IoT raises many in-the-small and in-the-large issues involving SO programming, IoT system architecture/middleware and methods/methodologies for the development of SO-based applica...

The advantages of using 3D models for restoration, preservation, and documentation of valuable historical and architectural objects have been numerously demonstrated by scientists in the field. Moreover, 3D model visualization in virtual reality has been recognized as an efficient, fast, and easy way of representing a variety of objects worldwide for present-day users, who have stringent requirements and high expectations. However, the main focus of recent research is the visual, geometric, and textural characteristics of a single concrete object, while integration of large numbers of models with additional information-such as historical overview, detailed description, and location-are missing. Such integrated information can be beneficial, not only for tourism but also for accurate documentation. For that reason, we demonstrate in this paper an integration of high-resolution spherical panoramas, a variety of maps, GNSS, sound, video, and text information for representation of numerous cultural heritage objects. These are then displayed in a web-based portal with an intuitive interface. The users have the opportunity to choose freely from the provided information, and decide for themselves what is interesting to visit. Based on the created web application, we provide suggestions and guidelines for similar studies. We selected objects, which are located in Bulgaria-a country with thousands of years of history and cultural heritage dating back to ancient civilizations. The methods used in this research are applicable for any type of spherical or cylindrical images and can be easily followed and applied in various domains. After a visual and metric assessment of the panoramas and the evaluation of

    We examine the influence of a positive attitude towards technology, number of social media network memberships and grade-point average (GPA) on global citizenship identification antecedents and outcomes. Students (N = 3628) at a university in the Philippines completed a survey assessing the above constructs. The results showed that attitude towards technology, number of social network site memberships and GPA-predicted global citizenship identification, and subsequent prosocial outcomes (e.g. intergroup helping, responsibility to act for the betterment of the world), through the perception that valued others prescribe a global citizen identity (normative environment) and perceived knowledge of the world and felt interconnectedness with others (global awareness). The results highlight the associations between technology and academic performance with a global identity and associated values.

    Vixen is a collection of enabling technologies for uninhibited distributed object computing. In the Spring of 1995 when Vixen was proposed, it was an innovative idea very much ahead of its time. But today the technologies proposed in Vixen have become standard technologies for Enterprise Computing. Sun Microsystems J2EE/EJB specifications, among others, are independently proposed technologies of the Vixen type. I have brought Vixen completely under the J2EE standard in order to maximize interoperability and compatibility with other computing industry efforts. Vixen and the Enterprise JavaBean (EJB) Server technologies are now practically identical; OIL, another Vixen technology, and the Java Messaging System (JMS) are practically identical; and so on. There is no longer anything novel or patentable in the Vixen work performed under this grant. The above discussion, notwithstanding, my independent development of Vixen has significantly helped me, my university, my students and the local community. The undergraduate students who worked with me in developing Vixen have enhanced their expertise in what has become the cutting edge technology of their industry and are therefore well positioned for lucrative employment opportunities in the industry. My academic department has gained a new course: "Multi-media System Development", which provides a highly desirable expertise to our students for employment in any enterprise today. The many Outreach Programs that I conducted during this grant period have exposed local Middle School students to the contributions that NASA is making in our society as well as awakened desires in many such students for careers in Science and Technology. I have applied Vixen to the development of two software packages: (a) JAS: Joshua Application Server - which allows a user to configure an EJB Server to serve a J2EE compliant application over the world wide web; (b) PCM: Professor Course Manager: a J2EE compliant application for configuring a

    Hewlett-Packard Laboratories, 1501 Page Mill Road, Palo Alto, CA 94304, USA Introduction The USENIX Conference on Object-Oriented Technologies and Systems (COOTS) is held annually in the late spring. The conference evolved from a set of C++ workshops that were held under the auspices of USENIX, the first of which met in 1989. Given the growing diverse interest in object-oriented technologies, the C++ focus of the workshop eventually became too narrow, with the result that the scope was widened in 1995 to include object-oriented technologies and systems. COOTS is intended to showcase advanced R&D efforts in object-oriented technologies and software systems. The conference emphasizes experimental research and experience gained by using object-oriented techniques and languages to build complex software systems that meet real-world needs. COOTS solicits papers in the following general areas: application of, and experiences with, object-oriented technologies in particular domains (e.g. financial, medical, telecommunication); the architecture and implementation of distributed object systems (e.g. CORBA, DCOM, RMI); object-oriented programming and specification languages; object-oriented design and analysis. The 4th meeting of COOTS was held 27 - 30 April 1998 at the El Dorado Hotel, Santa Fe, New Mexico, USA. Several tutorials were given. The technical program proper consisted of a single track of six sessions, with three paper presentations per session. A keynote address and a provocative panel session rounded out the technical program. The program committee reviewed 56 papers, selecting the best 18 for presentation in the technical sessions. While we solicit papers across the spectrum of applications of object-oriented technologies, this year there was a predominance of distributed, object-oriented papers. The accepted papers reflected this asymmetry, with 15 papers on distributed objects and 3 papers on object-oriented languages. The papers in this special issue are

    Concurrent object-oriented languages, particularly fine-grained approaches, reduce the difficulty of large scale concurrent programming by providing modularity through encapsulation while exposing large degrees of concurrency. Despite these programmability advantages, such languages have historically suffered from poor efficiency. This paper describes the Concert project whose goal is to develop portable, efficient implementations of fine-grained concurrent object-oriented languages. Our approach incorporates aggressive program analysis and program transformation with careful information management at every stage from the compiler to the runtime system. The paper discusses the basic elements of the Concert approach along with a description of the potential payoffs. Initial performance results and specific plans for system development are also detailed.

    Full Text Available There has been demands of context-aware systems in a hospital domain and several types of sensors have been applied as sources of medical activities. Unlike the previous passive RFID use of simply identifying objects this paper presents a system for motion detection of medical objects in a trauma bay by ranging the received signal strength indication RSSI using UHF passive RFID tags as one of those sensors that provide information on medical activities. To use passive RFID RSSI for motion detection Three different types of RSSI estimators are evaluated to process noisy RSSI and the adaptive threshold is proposed in the system to improve the resolution of detecting motion. Our system has been tested with recorded RSSI values in a laboratory and an actual trauma bay during simulated resuscitations performed by trauma teams. The proposed system has achieved 85.9 - 92.1 accuracies for most passive items that are used in a trauma bay.

    Information extraction for dominant tree group types is difficult in remote sensing image classification, howevers, the object-oriented classification method using high spatial resolution remote sensing data is a new method to realize the accurate type information extraction. In this paper, taking the Jiangle Forest Farm in Fujian Province as the research area, based on the Quickbird image data in 2013, the object-oriented method was adopted to identify the farmland, shrub-herbaceous plant, young afforested land, Pinus massoniana, Cunninghamia lanceolata and broad-leave tree types. Three types of classification factors including spectral, texture, and different vegetation indices were used to establish a class hierarchy. According to the different levels, membership functions and the decision tree classification rules were adopted. The results showed that the method based on the object-oriented method by using texture, spectrum and the vegetation indices achieved the classification accuracy of 91.3%, which was increased by 5.7% compared with that by only using the texture and spectrum.

    Full Text Available This paper proposed an algorithm to track the obstacle position and avoid the moving objects for differential driving Automatic Guided Vehicles (AGV system in industrial environment. This algorithm has several abilities such as: to detect the moving objects, to predict the velocity and direction of moving objects, to predict the collision possibility and to plan the avoidance maneuver. For sensing the local environment and positioning, the laser measurement system LMS-151 and laser navigation system NAV-200 are applied. Based on the measurement results of the sensors, the stationary and moving obstacles are detected and the collision possibility is calculated. The velocity and direction of the obstacle are predicted using Kalman filter algorithm. Collision possibility, time, and position can be calculated by comparing the AGV movement and obstacle prediction result obtained by Kalman filter. Finally the avoidance maneuver using the well known tangent Bug algorithm is decided based on the calculation data. The effectiveness of proposed algorithm is verified using simulation and experiment. Several examples of experiment conditions are presented using stationary obstacle, and moving obstacles. The simulation and experiment results show that the AGV can detect and avoid the obstacles successfully in all experimental condition.

    This study was designed to compare achievement, attitudes toward success in mathematics, and mathematics anxiety of college students taught brief calculus using a graphic calculator, with the achievement and attitudes and anxiety of students taught using the computer algebra system Maple, using a technology based text book. 50 men and 50 women, students in three classes at a large public university in the southwestern United States, participated. Students' achievement in brief calculus was measured by performance on a teacher-made achievement test given at the end of the study. Analysis of variance showed no significant difference in achievement between the groups. To measure change in attitudes and anxiety, responses to paper-and-pencil inventories indicated significant differences in favor of students using the computer.

    2011-01-01

    Attitudes and attitude change remain core topics of contemporary social psychology. This selective review emphasizes work published from 2005 to 2009. It addresses constructionist and stable-entity conceptualizations of attitude, the distinction between implicit and explicit measures of attitude, and implications of the foregoing for attitude change. Associative and propositional processes in attitude change are considered at a general level and in relation to evaluative conditioning. The role of bodily states and physical perceptions in attitude change is reviewed. This is followed by an integrative perspective on processing models of persuasion and the consideration of meta-cognitions in persuasion. Finally, effects of attitudes on information processing, social memory, and behavior are highlighted. Core themes cutting across the areas reviewed are attempts at integrative theorizing bringing together formerly disparate phenomena and viewpoints.

    Position and orientation estimation of the object, which can be widely applied in the fields as robot navigation, surgery, electro-optic aiming system, etc, has an important value. The monocular vision positioning algorithm which is based on the point characteristics is studied and new measurement method is proposed in this paper. First, calculate the approximate coordinates of the five reference points which can be used as the initial value of iteration in the camera coordinate system according to weakp3p; Second, get the exact coordinates of the reference points in the camera coordinate system through iterative calculation with the constraints relationship of the reference points; Finally, get the position and orientation of the object. So the measurement model of monocular vision is constructed. In order to verify the accuracy of measurement model, a plane target using infrared LED as reference points is designed to finish the verification of the measurement method and the corresponding image processing algorithm is studied. And then The monocular vision experimental system is established. Experimental results show that the translational positioning accuracy reaches +/-0.05mm and rotary positioning accuracy reaches +/-0.2o .

    Xing, Suxia; Liu, Peng

    In this effort, we proposed an new image fusion technique, utilizing Renyi entropy's object extraction and Non-Subsampled Contourlet Transform (NSCT), for improved visible effect of the image. NSCT is a multiscale transform method, it is a shift-invariant, linear phase, ``true" two-dimensional transform that can decomposes an image into any directional sub-images to capture the intrinsic geometrical structure. In this paper we decompose visible image into 21, 22, and 23 directional sub-images at three different level respectively. Image enhancement is performed at the decomposition level and fused. Renyi entropy is a generalized information entropy. Infrared image can be divided into two parts of the object and the background through the maximum value of Renyi entropy. Image fusion is performed after NSCT and Renyi entropy. The fused image has significantly improved brightness and higher contrast than other images. In order to evaluate the proposed method, information entropy (IE), standard deviation (STD), spatial frequency (SF) and mutual information (MI) are adopted to compare with Laplace, wavelet, and NSCT et al. Results are shown that all evaluation value of the proposed method is higher than that of other methods, and it is a better image fusion method.

    2015-01-01

    Full Text Available In this article the author, using examples from the recent past on data of the all-Russian polls, remarks on changing human environment innovations, which provide scientific and technical progress. The article investigates the impact assessment of the results of scientific and technical achievements, positive and negative predictions of the effects of an increasingly wide application of high-tech products in everyday life. A comparative sociological analysis of the studies' results, conducted in Russia and foreign countries regarding the impact of progress on humanity, is shown. The author's conclusions are presented: Russians refer to the achievements of scientific-technical progress as positive, but not so optimistic as, for example, Americans. The respondents are afraid of the intervention of new technologies in natural evolutionary and genetic processes, substitution of human relations to relations of order "technology and people", the proliferation of military equipment in civilian life. The author pays special attention to the role of women in environmental issues, which exhibits a strong response to the threats of environmental pollution and, as a rule, more critically perceive the environmental situation.

    Exposure to alcohol marketing within alcohol retailers has been associated with higher rates of childhood drinking, brand recognition, and marketing recall. This study aimed to objectively measure children's everyday exposure to alcohol marketing within supermarkets. Children aged 11-13 (n = 167) each wore a wearable camera and GPS device for four consecutive days. Micro-spatial analyses were used to examine exposures within supermarkets. In alcohol retailing supermarkets (n = 30), children encountered alcohol marketing on 85% of their visits (n = 78). Alcohol marketing was frequently near everyday goods (bread and milk) or entrance/exit. Alcohol sales in supermarkets should be banned in order to protect children from alcohol marketing.

    Demand among large office buildings for the energy-saving benefits of the HVAC (Heating, Ventilating and Air-Conditioning) System are increasing as more and more people become concerned with global environmental issues. However, immoderate measures taken in the interest of energy conservation may encroach on the thermal comfort and productivity level of office workers. Building management should satisfy both indoor thermal comfort and energy conservation while adapting to the many regulatory, social, climate, and other changes that occur during the lifespan of the building. This paper demonstrates how optimal control of the HVAC system, based on data modeling and the multi-objective optimal method, achieves an efficient equilibrium between thermal comfort and energy conservation.

    Science.gov (United States)

    Paul, Norbert W

    2009-09-01

    Since decades, scientific change has been interpreted in the light of paradigm shifts and scientific revolutions. The Kuhnian interpretation of scientific change however is now more and more confronted with non-disciplinary thinking in both, science and studies on science. This paper explores how research in biomedicine and the life sciences can be characterized by different rationalities, sometimes converging, sometimes contradictory, all present at the same time with varying ways of influence, impact, and visibility. In general, the rationality of objects is generated by fitting new objects and findings into a new experimental context. The rationality of hypotheses is a move towards the construction of novel explanatory tools and models. This is often inseparable meshing with the third, the technological rationality, in which a technology-driven, self-supporting and sometimes self-referential refinement of methods and technologies comes along with an extension into other fields. During the second and the third phase, the new and emerging fields tend to expand their explanatory reach not only across disciplinary boundaries but also into the social sphere, creating what has been characterized as "exceptionalism" (e.g. genetic exceptionalism or neuro-exceptionalism). Finally, recent biomedicine and life-sciences reach a level in which experimental work becomes more and more data-driven because the technologically constructed experimental systems generate a plethora of findings (data) which at some point start to blur the original hypotheses. For the rationality of information the materiality of research practices becomes secondary and research objects are more and more getting out of sight. Finally, the credibility of science as a practice becomes more and more dependent on consensus about the applicability and relevance of its results. The rationality of interest (and accountability) has become more and more characteristic for a research process which is no longer

    The economic and social benefits of developing cost competitive solar thermal technologies (STT) were assessed. The analysis was restricted to STT in electric applications for 16 high insolation/high energy price states. Three fuel price scenarios and three 1990 STT system costs were considered, reflecting uncertainty over fuel prices and STT cost projections. After considering the numerous benefits of introducing STT into the energy market, three primary benefits were identified and evaluated: (1) direct energy cost savings were estimated to range from zero to $50 billion; (2) oil imports may be reduced by up to 9 percent, improving national security; and (3) significant environmental benefits can be realized in air basins where electric power plant emissions create substantial air pollution problems. STT research and development was found to be unacceptably risky for private industry in the absence of federal support. The normal risks associated with investments in research and development are accentuated because the OPEC cartel can artificially manipulate oil prices and undercut the growth of alternative energy sources.

    Full Text Available Background: Periodic general health examinations (GHEs are gradually becoming more popular as they employ subclinical screenings, as a means of early detection. This study considers the effect of information technology (IT, health communications and the public’s attitude towards GHEs in Vietnam. Methods: A total of 2,068 valid observations were obtained from a survey in Hanoi and its surrounding areas. Results: In total, 42.12% of participants stated that they were willing to use IT applications to recognise illness symptoms, and nearly 2/3 of them rated the healthcare quality at average level or below. Discussion: The data, which was processed by the BCL model, showed that IT applications (apps reduce hesitation toward GHEs; however, older people seem to have less confidence in using these apps. Health communications and government’s subsidy also increased the likelihood of people attending periodic GHEs. The probability of early check-ups where there is a cash subsidy could reach approximately 80%.

    Species” of military aircraft, commercial aircraft and private cars have been chosen in our analysis as illustrations of the fruitfulness of the “ holistic” approach. The obtained data show that both commercial “ species” exhibit similar “ survival dynamics” in compare with those of the military species of aircraft: lifetime distributions were found to be Weibull distributions for all “ species” however for commercial vehicles, the shape parameters were a little higher than 2, and scale parameters were 19.8 years (aircraft) and 21.7 (cars) whereas for military aircraft, the shape parameters were much higher and the mean time to failure much longer. The difference between the lifetime characteristics of the “ species” can be attributed to the differences in the social, operational, economic and safety-and-reliability requirements and constraints. The obtained information can be used to make tentative predictions for the most likely trends in the given field of vehicular technology. The following major conclusions can be drawn from our analysis: 1) The suggested concept based on the use of HLPFs reflects the current state and the general perceptions in the given field of engineering, including aerospace technologies, and allows for all the inherent and induced factors to be taken into account: any type of failures, usage profiles, economic factors, environmental conditions, etc. The concept requires only very general input data for the entire population. There is no need for the less available information about individual articles. 2) Failure modes are not restricted to the physical type of failures and include economic, cultural or social effects. All possible causes, which might lead to making a decision to terminate the use of a particular type

    Reingold, Eyal M

    2014-03-01

    Two methods for objectively measuring eye tracking data quality are explored. The first method works by tricking the eye tracker to detect an abrupt change in the gaze position of an artificial eye that in actuality does not move. Such a device, referred to as an artificial saccade generator, is shown to be extremely useful for measuring the temporal accuracy and precision of eye tracking systems and for validating the latency to display change in gaze contingent display paradigms. The second method involves an artificial pupil that is mounted on a computer controlled moving platform. This device is designed to be able to provide the eye tracker with motion sequences that closely resemble biological eye movements. The main advantage of using artificial motion for testing eye tracking data quality is the fact that the spatiotemporal signal is fully specified in a manner independent of the eye tracker that is being evaluated and that nearly identical motion sequence can be reproduced multiple times with great precision. The results of the present study demonstrate that the equipment described has the potential to become an important tool in the comprehensive evaluation of data quality.

    2017-09-01

    The importance of automated prism tracking is increasingly triggered by the rising automation of total station measurements in machine control, monitoring and one-person operation. In this article we summarize and explain the different techniques that are used to coarsely search a prism, to precisely aim at a prism, and to identify whether the correct prism is tracked. Along with the state-of-the-art review, we discuss and experimentally evaluate possible improvements based on the image data of an additional wide-angle camera which is available for many total stations today. In cases in which the total station's fine aiming module loses the prism, the tracked object may still be visible to the wide-angle camera because of its larger field of view. The theodolite angles towards the target can then be derived from its image coordinates which facilitates a fast reacquisition of the prism. In experimental measurements we demonstrate that our image-based approach for the coarse target search is 4 to 10-times faster than conventional approaches.

  3. The structure and strength of public attitudes towards wind farm development

    Science.gov (United States)

    Bidwell, David Charles

    A growing social science literature seeks to understand why, despite broad public support for wind energy, proposals for specific projects are often met with strong local opposition. This gap between general and specific attitudes is viewed as a significant obstacle to the deployment of wind energy technologies. This dissertation applies theoretical perspectives and methodological tools from social psychology to provide insights on the structure and strength of attitudes towards the potential development of commercial wind farm in three coastal areas of Michigan. A survey of attitudes was completed by 375 residents in these communities and structural equation modeling was used to explore the relationship among variables. The analysis found that attitudes towards wind farm development are shaped by anticipated economic benefits to the community, but expectations of economic benefit are driven by personal values. Social psychology has long recognized that all attitudes are not created equal. Weak attitudes are fleeting and prone to change, while strong attitudes are stable over time and resistant to change. There are two fundamental paths to strong attitudes: repeated experience with an attitude object or the application of deeply held principles or values to that object. Structural equation models were also used to understand the strength of attitudes among the survey respondents. Both the anticipated effects of wind farm development and personal values were found to influence the strength of attitudes towards wind farms. However, while expectations that wind farm development will have positive effects on the economy bolster two measures of attitude strength (collective identity and importance), these expectations are associated with a decline in a third measure (confidence). A follow-up survey asking identical questions was completed by completed by 187 respondents to the initial survey. Linear regressions models were used to determine the effects of attitude

    The Los Alamos Large Scale Demonstration and Deployment Project (LSDDP) in support of the US Department of Energy (DOE) Deactivation and Decommissioning Focus Area (DDFA) is identifying and demonstrating technologies to reduce the cost and risk of management of transuranic element contaminated large metal objects, i.e. gloveboxes. The previously conducted demonstrations supported characterization and ''front end'' aspects of the Los Alamos Decontamination and Volume Reduction System (DVRS) project. The first demonstration was shown to save the DVRS project approximately $200,000 per year and characterization technologies have been estimated to save DVRS a month of DVRS operation per year. In FY01 demonstrations for decontamination technologies, communication systems, and waste data collection systems have provided additional savings equivalent to another $200K per year of operation. The Los Alamos Large Scale demonstration and Deployment Project continues to provide substantial cost savings to the DVRS process in this second round of demonstrations. DVRS cost savings of $400K per year can now be counted, with additional efficiency savings of up to 30% on many tasks.

    Full Text Available Increased environmental awareness has been deeply affecting consumer behaviour and increasing green marketing importance for organizations. The aim of this study is to analyze the IT professionals (Information Technology perception about actions related to green marketing (considering environmental issues in all product marketing stages, since production, through the use and disposal by the consumer and propose socially planned changes so they can maintain or enhance practices related to green IT actions taken by IT professionals with a focus on environmental sustainability. To this end, we measured the attitudes towards green IT using the Expectancy-Value model beyond its knowledge level about environmental problems and their buying environmentally friendly products. From the results obtained we used the strategies composite typology for social change planned in order to propose actions to change or reinforce  behaviour as regards green marketing on the part of IT professionals. Qualitative surveys were conducted to identify the beliefs and its consequences (attitudes and then quantitative research to measure attitudes, engagement and knowledge about green IT. The results indicate that IT professionals can be considered engaged and positive attitudes towards green marketing. Therefore a reinforcement strategy is suggested through economic and psychological incentives to maintain and foster this behaviour in relation to green IT.

    attitude theory. Why is this important? Attitudinal concepts can be found in every area of marketing. Concepts like ad liking, brand attitude, quality perception, product preference, perceived benefit, perceived risk, perceived value, and customer satisfaction can all be understood as particular types...... of attitudes. This is the reason why a thorough understanding of attitudes is one of the most important skills a marketer can have. That same is true in related areas such as communications research: concepts like public opinion, corporate reputation, and corporate image are nothing more than particular types...

    2015-08-01

    The authors propose a framework distinguishing two types of lateral attitude change (LAC): (a) generalization effects, where attitude change toward a focal object transfers to related objects, and (b) displacement effects, where only related attitudes change but the focal attitude does not change. They bring together examples of LAC from various domains of research, outline the conditions and underlying processes of each type of LAC, and develop a theoretical framework that enables researchers to study LAC more systematically in the future. Compared with established theories of attitude change, the LAC framework focuses on lateral instead of focal attitude change and encompasses both generalization and displacement. Novel predictions and designs for studying LAC are presented.

    Full Text Available The present study concentrated on the interplay of subjective norms and attitudes towards WebCT over time in a U.S. higher education setting. Panel data collected on three occasions over the course of a semester were investigated in a Web-enhanced hybrid undergraduate psychology course, using a crosslagged and autoregressive model. Results suggested: 1. the degree to which students report deferring to their professor s expectations and peer opinions (subjective norms influences the degree to which they, on future occasions, report deferring to their professor s expectations and peer opinions; 2. students attitudes towards using WebCT influence their attitudes assessed on immediately following occasions, but only those attitudes assessed immediately afterwards; 3. the degree to which students report deferring to professorial expectations and peer opinions (subjective norms influences contemporaneously measured attitudes toward WebCT use; 4. student attitudes regarding WebCT use actually influence how students on a later occasion report their degree of deference to professorial expectations and peer opinions (subjective norms. Further research was suggested.

    Full Text Available This study from the Norwegian University of Science and Technology (NTNU examines students’ learning goals and attitudes toward mathematics in a first-year calculus course in undergraduate engineering education. Achievement motivation research using the Achievement Goal Questionnaire (AGQ is advanced from current literature with two additions: (1 a course specific context using introductory college calculus students, and (2 participation of Norwegian students.Pre- and posttest measures of attitudes indicate that students do change learning goals over time, unfortunately opposite to the instructors’ aspirations. A significant increase in “Mastery Avoidance” and “Work Avoidance” was accompanied with a drop in “Mastery Approach” and “Performance Approach”. Variables such as value, motivation and enjoyment decreased along with a significant drop in self-confidence.

  11. The effects of geographic information system (GIS) technologies on students' attitudes, self-efficacy, and achievement in middle school science classrooms

    Baker, Thomas Ray

    Since the publication of the National Science Education Standards , a concerted and evolving movement to make science classrooms more inquiry-oriented has been building. The proliferation of models of teaching and learning where questions and investigations drive learning, while not new are also not easy to plan, implement, or evaluate. In order to make the vision of the Standards come to fruition, educators are calling on the tools of technology to support and foster the shift to scientific inquiry or classroom research. The use of certain data analysis technologies have been suggested to be a particularly powerful ally in the struggle to extend classroom teaching and learning into the realm of problem-driven classroom inquiry. The use of a Geographic Information System (GIS), a technology allowing for the graphical representation of data with a geographic component seems to be one technology that can adequately bolster the dynamic and complex needs of the science classroom engaged in scientific inquiry. In this study, eighth grade Earth science students studying relative, local air quality indicators were divided in two groups; a treatment group that utilized GIS-supported scientific inquiry and a control group that used traditional mapping techniques to support their study. Student attitudes regarding science and technology were measured with a pre/post instrument across the study. Individual student efforts were summarily evaluated with a modified Kansas Science Performance Based Assessment rubric. During the two-week treatment, the students using the GIS-supported materials were found to show positive and significant improvements in science self-efficacy and attitudes toward technology. While female attitudes and self-efficacy were not found to change, males significantly improved on all affective factors. Students using GIS also performed significantly better than traditional mapping students on science process skills, specifically data analysis techniques

    Full Text Available Objective – To investigate whether African American students’ computer attitudes predict levels of library anxiety. Design – A user study in which two instruments were administered to a group of graduate students to measure computer attitudes and library anxiety. Setting – The College of Education at an historically black college and university in the United States of America. Subjects – Ninety ‐four, predominantly female, African American graduate students, ranging in age from 22 ‐62 years old, and enrolled in either a statistics or a measurement course. Methods – Two instruments, the Computer Attitude Scale (CAS and the Library Anxiety Scale (LAS were administered to all the study participants. The Computer Anxiety Scale contains forty Likert ‐type items that assess individuals’ attitudes toward computers and their use. It includes four scales which can be administered separately: 1. Anxiety or fear of computers 2. Confidence in the ability to use computers 3. Liking or enjoying working with computers 4. Computer usefulnessThe LAS contains forty ‐three, 5 ‐point, Likert ‐format items that assess levels of library anxiety experienced by college students. It also has five subscales as follows: 1. Barriers with staff 2. Affective barriers 3. Comfort with the library 4. Knowledge of the library 5. Mechanical barriers Main results – There were twenty correlations between the library anxiety subscale scores and the computer attitude subscale scores. Four of these correlations were statistically significant. Liking or enjoying working with computers was statistically significantly linked to affective barriers, comfort with the library, and knowledge of the library. There was also a statistically significant association between an attitude of computer usefulness and knowledge of the library. Conclusion – These findings suggest that in this group of students there is a medium to strong relationship between computer

    Background Little is known about health providers’ attitudes toward visual inspection with acetic acid (VIA) and cryotherapy in the prevention of cervical cancer, as most research in Latin America and the Caribbean (LAC) has examined attitudes of the general population. This study describes attitudes of Bolivian health professionals toward new technologies for cervical cancer prevention, focusing on VIA and cryotherapy. Methods Between February 2011 and March 2012, we surveyed 7 nurses and 35 physicians who participated in 5-day workshops on VIA and cryotherapy conducted in Bolivia. Multiple choice and open-ended questions were used to assess participants’ acceptability of these procedures and the feasibility of their implementation in the context of perceived barriers for the early detection of cervical cancer in this country. Results Most believed that cultural factors represent the main barrier for the early detection of cervical cancer (70%), although all stated that VIA and cryotherapy would be accepted by women, citing the advantages of VIA over cytology for this belief. Most also believed their colleagues would accept VIA and cryotherapy (71%) and that VIA should replace Pap testing (61%), reiterating the advantages of VIA for these beliefs. Those who believed the contrary expressed a general resistance to change associated with an already existing cytology program and national norms prioritizing Pap testing. Conclusions Most participants had favorable attitudes toward VIA and cryotherapy; however, a sizable minority cited challenges to their adoption by colleagues and believed VIA should not replace cytology. This report can inform the development of strategies to expand the use of alternative cervical cancer screening methods in LAC and Bolivia. PMID:22816515

    Full Text Available Information and communication technologies (ICTs are increasingly influencing human beings and are changing our attitudes towards these technologies. The purpose of this article is to understand the factors influencing the use of ICTs in agricultural extension through a descriptive research method. The populations were 320 individuals of agricultural Extension Workers (EWs of Isfahan province that 200 people selected as a research sample. The reliability of self-completion questionnaire according to pilot test and calculating Cronbach's alpha for four part of the instrument was 82.6 - 87.8. The results revealed that the EWs have a positive attitude toward using ICT. They mostly viewed it as a useful tool for extension, which can potentially save money and time and extension. On the ranking of principal areas of applying ICTs by EWs “typing letters/report”, “prepare and protect file on process basic agricultural and rural information”, had most usage. The main result of the study revealed that the EWs approximately use ICT quite a bit. Also, the EWs with high school diploma degree used ICT less than the EWs with MSc degree and the EWs with 5 years and less experience had higher ICT application than the EWs with 15-16 year experience.

    This mixed-methods study was designed to explore young Australian men's attitudes and behaviour in relation to mental health and technology use to inform the development of online mental health services for young men. National online survey of 486 males (aged 16 to 24) and 17 focus groups involving 118 males (aged 16 to 24). Young men are heavy users of technology, particularly when it comes to entertainment and connecting with friends, but they are also using technology for finding information and support. The focus group data suggested that young men would be less likely to seek professional help for themselves, citing a preference for self-help and action-oriented strategies instead. Most survey participants reported that they have sought help for a problem online and were satisfied with the help they received. Focus group participants identified potential strategies for how technology could be used to overcome the barriers to help-seeking for young men. The key challenge for online mental health services is to design interventions specifically for young men that are action-based, focus on shifting behaviour and stigma, and are not simply about increasing mental health knowledge. Furthermore, such interventions should be user-driven, informed by young men's views and everyday technology practices, and leverage the influence of peers.

    As cultural sector practice becomes increasingly dependent on digital technologies for the production, display, and dissemination of art and material heritage, it is important that those working in the sector understand the basic scientific principles underpinning these technologies and the social, political and economic implications of exploiting them. The understanding of issues in cultural heritage preservation and digital heritage begins in the education of the future stakeholders and the innovative integration of technologies into the curriculum. This paper gives an example of digital technology skills embedded into a module in the interdisciplinary UCL Bachelor of Arts and Sciences, named "Technologies in Arts and Cultural Heritage", at University College London.

    Full Text Available The overall objective of the study was to determine the attitudes associated with issues about the production of wheat. We have analyzed the responses of 130 wheat producers from the five counties of eastern Croatia, deliberately chosen from the Farm Register. The questionnaire contained several themes: Country-policy-agricultural production, Production Technology-Economy, Purchase of wheat and Wheat production and impact of EU accession. It appears that participants have the most positive attitudes in the aspect of Production Technology-Economy, and the most negative in the aspect of Country-policy-agricultural production. In the aspect of Production Technology-Economy, more positive attitudes have participants who work in economies with a large number of members (more than 5. Low to medium high positive significant correlations, found between certain aspects of attitudes about wheat production, suggest that the attitudes to all questions related to the production of wheat are similar. Older workers (age group 61-80 years have a negative attitude to the aspects of Production Technology-Economy and Wheat production and impact of EU accession. Among the links between certain aspects of attitudes on wheat production with selected agroeconomics indicators, highlights the finding that some of these indicators are negatively associated with private ownership of land, and positively with the lease of the land, in separate aspects of Production Technology-Economy, Purchase wheat and Influence of entry into the EU.

    2017-02-03

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

    Full Text Available Objectives: The study examined and identified the factors that affect lawyers’ attitudes to knowledge sharing, and their knowledge sharing behaviour. Specifically, it investigated the relationship between the salient beliefs affecting the knowledge sharing attitude of lawyers’, and applied a modified version of the Theory of Reasoned Action (TRA in the knowledge sharing context, to predict how these factors affect their knowledge sharing behaviour.Method: A field survey of 273 lawyers was carried out, using questionnaire for data collection. Collected data on all variables were structured into grouped frequency distributions. Principal Component Factor Analysis was applied to reduce the constructs and Simple Regression was applied to test the hypotheses. These were tested at 0.05% level of significance.Results: Results showed that expected associations and contributions were the major determinants of lawyers’ attitudes towards knowledge sharing. Expected reward was not significantly related to lawyers’ attitudes towards knowledge sharing. A positive attitude towards knowledge sharing was found to lead to a positive intention to share knowledge, although a positive intention to share knowledge did not significantly predict a positive knowledge sharing behaviour. The level of Information Technology (IT usage was also found to significantly affect the knowledge sharing behaviour of lawyers’.Conclusion: It was recommended that law firms in the study area should deploy more IT infrastructure and services that encourage effective knowledge sharing amongst lawyers.

    While much literature has been devoted to theoretical explanations of the learning processes of older adults and to the methods of teaching best utilized in older populations, less has focused on the education of older adults who reside in assisted and independent living communities (AICs), especially with regards to information and communication technology (ICT) education. The purpose of this study is to determine whether participants' attitudes and views towards computers and the Internet are affected as a result of participating in an eight-week training program designed to enhance computer and Internet use among older adults in such communities. Specifically, we examine if ICT education specially designed for AIC residents results in more positive attitudes towards ICTs and a perceived decrease in factors that may limit or prevent computer and Internet use. We discuss the implications of these results for enhancing the quality of life for older adults in AICs and make recommendations for those seeking to decrease digital inequality among older adults in these communities through their own ICT classes.

    2016-01-01

    Teachers deal with Information and Communications Technology (ICT) every day and they often have to solve problems by themselves. To help them in coping with this issue, an online support program has been created, where teachers can pose their problems on ICT and they can receive solutions from other teachers. A Recommender System has been defined and implemented into the support program to suggest to each teacher the most suitable solution based on her Skills, Competences, and Attitude toward ICT (SCAT-ICT). The support program has initially been populated with 70 problems from 86 teachers. 30 teachers grouped these problems into six categories with the card-sorting technique. Real solutions to these problems have been proposed by 25 trained teachers. Finally, 17 teachers evaluated the usability of the support program and the Recommender System, where results showed a high score on the standardized System Usability Scale.

    Howe, Lauren C; Krosnick, Jon A

    2017-01-03

    Attitude strength has been the focus of a huge volume of research in psychology and related sciences for decades. The insights offered by this literature have tremendous value for understanding attitude functioning and structure and for the effective application of the attitude concept in applied settings. This is the first Annual Review of Psychology article on the topic, and it offers a review of theory and evidence regarding one of the most researched strength-related attitude features: attitude importance. Personal importance is attached to an attitude when the attitude is perceived to be relevant to self-interest, social identification with reference groups or reference individuals, and values. Attaching personal importance to an attitude causes crystallizing of attitudes (via enhanced resistance to change), effortful gathering and processing of relevant information, accumulation of a large store of well-organized relevant information in long-term memory, enhanced attitude extremity and accessibility, enhanced attitude impact on the regulation of interpersonal attraction, energizing of emotional reactions, and enhanced impact of attitudes on behavioral intentions and action. Thus, important attitudes are real and consequential psychological forces, and their study offers opportunities for addressing behavioral change.

  20. Wybór obiektywnej niepewności jako postawa filozofii egzystencji. Soren Kierkegaard i Odo Marquard (Choosing Objective Uncertainty as an Attitude of Existential Philosophy. Soren Kierkegaard and Odo Marquard

    Directory of Open Access Journals (Sweden)

    Dominika Boroń

    2011-12-01

    Full Text Available The idea of the article is to search for the roots of the so-called existential thinking, using the peculiar comparison: of the religiously oriented ideas of Kierkegaard ( especially his notions of subjective and objective thinker and the idea of subjective truthand contemporary ideas of Odo Marquard’s hermeneutical skepticism. Surprisingly, Marquard’s anthropologically and sociologically oriented reflection, while dealing with the problem of human search for absolute knowledge and its depreciation of particular existence, comes to much the same reflections as Kierkegaard: stating rational inability to reach The Objective. Both philosophers analyze the dynamics of the thinking subject and come to more similar statements: Kierkegaard’s notion of objective uncertainty can be, to the certain extent, used to describe attitude of modern thinker described by Marquard. “To the certain extent” – because it is hard and not legitimized to avoid in interpretation the ultimate religious goal that ties up the whole Kierkegaard’s authorship and makes his thought so specific. But the similarities are not meant just to be shown here: they aim to point out certain, very substantial reflection that lies at the root of the existential thinking and makes it still necessary. It is the reflection that sees human mortality, individuality and the dynamic character of the self as the basis for giving primacy in philosophy to the “here and now” questions of how to live and die and how to share those questions with others.

    This article presents the synthesis of results from the Stanford Energy Modeling Forum Study 27, an inter-comparison of 19 energy-economy and integrated assessment models. The study investigated the value of individual mitigation technologies such as energy intensity improvements, carbon capture and sequestration (CCS), nuclear power, solar and wind power and bioenergy for climate mitigation. Achieving atmospheric greenhouse gas concentration targets at 450 and 550 ppm CO2 equivalent requires massive greenhouse gas emissions reductions. A fragmented policy approach at the level of current ambition is inconsistent with these targets. The availability of a negative emissions technology, in most models biofuels with CCS, proved to be a key element for achieving the climate targets. Robust characteristics of the transformation of the energy system are increased energy intensity improvements and the electrification of energy end use coupled with a fast decarbonization of the electricity sector. Non-electric energy end use is hardest to decarbonize, particularly in the transport sector. Technology is a key element of climate mitigation. Versatile technologies such as CCS and bioenergy have largest value, due in part to their combined ability to produce negative emissions. The individual value of low-carbon power technologies is more limited due to the many alternatives in the sector. The scale of the energy transformation is larger for the 450 ppm than for the 550 ppm CO2e target. As a result, the achievability and the costs of the 450 ppm target are more sensitive to variations in technology variability. Mitigation costs roughly double when moving from 550 ppm to 450 ppm CO2e, but remain below 3% of GDP for most models.

  19. Attutude-action consistency and social policy related to nuclear technology

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    This study reports the results of a further analysis of questionnaire data--parts of which have been previously reported by Lindell, Earle, Hebert and Perry (1978)--that are related to the issue of consistency of attitudes and behavior toward nuclear power and nuclear waste management. Three factors are considered that might be expected to have a significant bearing on attitude-action consistency: social support, attitude object importance and past activism. Analysis of the data indicated that pronuclear respondents were more likely to show consistency of attitudes and actions (66%) than were antinuclear respondents (51%) although the difference in proportions is not statistically significant. Further analyses showed a strong positive relation between attitude-action consistency and perceived social support, measured by the degree to which the respondent believed that close friends and work associated agreed with his attitude. This relationship held up even when controls for attitude object importance and past activism were introduced. Attitude object importance--the salience of the issue of energy shortage--had a statistically significant effect only when perceived social support was low. Past activism had no significant relation to attitude-action consistency. These data suggest that the level of active support for or opposition to nuclear technology will be affected by the distribution of favorable and unfavorable attitudes among residents of an area. Situations in which pro- and antinuclear attitudes are concentrated among members of interacting groups, rather than distributed randomly, are more likely to produce high levels of polarization.

    Full Text Available The purpose of this article is to apply the methodology to structure the decision problem and select an appropriate LOR architecture. This reflected in the need to invest and improve the technology for educational organizations. Selecting an appropriate infrastructure for LOR is usually a complex decision, because it has conflicting attributes. In situations of uncertainty, multi-attribute utility theory (MAUT assists in selecting the best alternative according to criteria established by the decision maker. Results demonstrated that the choice of indexing and distributing LOR (A4 is less sensitive to changes and has greater utility. According to the analysis, A4 is the option most suitable for deploying IT infrastructure in the case of application. Researchers and professional managers can assess the types of ROA architecture and replicate this decision model to find similar results.

  7. Reviving Campbell's paradigm for attitude research.

    Science.gov (United States)

    Kaiser, Florian G; Byrka, Katarzyna; Hartig, Terry

    2010-11-01

    Because people often say one thing and do another, social psychologists have abandoned the idea of a simple or axiomatic connection between attitude and behavior. Nearly 50 years ago, however, Donald Campbell proposed that the root of the seeming inconsistency between attitude and behavior lies in disregard of behavioral costs. According to Campbell, attitude- behavior gaps are empirical chimeras. Verbal claims and other overt behaviors regarding an attitude object all arise from one "behavioral disposition." In this article, the authors present the constituents of and evidence for a paradigm for attitude research that describes individual behavior as a function of a person's attitude level and the costs of the specific behavior involved. In the authors' version of Campbell's paradigm, they propose a formal and thus axiomatic rather than causal relationship between an attitude and its corresponding performances. The authors draw implications of their proposal for mainstream attitude theory, empirical research, and applications concerning attitudes.

    2013-12-01

    In assessing brownfield sites for redevelopment, intrusive investigations are carried out to assess contamination, geology and hydrogeology. Such investigations are expensive, requiring the hire of expensive equipment, which incur standing charges when not in use. In addition, they provide information for discrete sample ';windows'. Non-intrusive methods have the ability to gather information across an entire area. Methods including electrical resistivity/conductivity and ground penetrating radar (GRP), and have been applied to brownfield sites. Their ability in detecting pollution e.g. buried canisters, is often restricted due to unfavourable on-site conditions e.g. GRP is not useful in cases where a layer of clay or reinforced concrete is present. This study is focused on the use, for the first time, of short period seismometers as an alternative, non-intrusive, passive seismic method to detect the presence of objects buried under the ground surface even when on-site conditions are not favourable. We used five low detection threshold seismometers with a flat response within the frequency range 1 - 80 Hz. We conducted experiments both in the lab and in the field. Three series of lab experiments were conducted in sand, under controlled conditions, using ambient noise as the only source of generating seismic waves. Results revealed that there is a distinct difference in the amplitude of the power density spectra of the recorded signals in cases where objects e.g. concrete block, polystyrene block, wood, were present. To validate these results in field scale, we conducted a series of experiments that took place in Heriot-Watt University campus on a field for which we had information for the subsurface from an electromagnetic survey. We used the same monitoring equipment to try and detect the presence of a 6m long PVC pipe buried 0.5m below the ground surface. Results were consistent with those obtained from lab experiments. This supports our initial hypothesis on the

    It is well known that accurate interpretation of the 12-lead electrocardiogram (ECG) requires a high degree of skill. There is also a moderate degree of variability among those who interpret the ECG. While this is the case, there are no best practice guidelines for the actual ECG interpretation process. Hence, this study adopts computerized eye tracking technology to investigate whether eye-gaze can be used to gain a deeper insight into how expert annotators interpret the ECG. Annotators were recruited in San Jose, California at the 2013 International Society of Computerised Electrocardiology (ISCE). Each annotator was recruited to interpret a number of 12-lead ECGs (N=12) while their eye gaze was recorded using a Tobii X60 eye tracker. The device is based on corneal reflection and is non-intrusive. With a sampling rate of 60Hz, eye gaze coordinates were acquired every 16.7ms. Fixations were determined using a predefined computerized classification algorithm, which was then used to generate heat maps of where the annotators looked. The ECGs used in this study form four groups (3=ST elevation myocardial infarction [STEMI], 3=hypertrophy, 3=arrhythmias and 3=exhibiting unique artefacts). There was also an equal distribution of difficulty levels (3=easy to interpret, 3=average and 3=difficult). ECGs were displayed using the 4x3+1 display format and computerized annotations were concealed. Precisely 252 expert ECG interpretations (21 annotators×12 ECGs) were recorded. Average duration for ECG interpretation was 58s (SD=23). Fleiss' generalized kappa coefficient (Pa=0.56) indicated a moderate inter-rater reliability among the annotators. There was a 79% inter-rater agreement for STEMI cases, 71% agreement for arrhythmia cases, 65% for the lead misplacement and dextrocardia cases and only 37% agreement for the hypertrophy cases. In analyzing the total fixation duration, it was found that on average annotators study lead V1 the most (4.29s), followed by leads V2 (3.83s

    Hopp, B.; Smausz, T.; Kresz, N.; Nagy, P. M.; Juhász, A.; Ignácz, F.; Márton, Z.

    Allergic-type diseases are current nowadays, and they are frequently caused by certain metals. We demonstrated that the metal objects can be covered by Teflon protective thin layers using a pulsed laser deposition procedure. An ArF excimer laser beam was focused onto the surface of pressed PTFE powder pellets; the applied fluences were 7.5-7.7 J/cm2. Teflon films were deposited on fourteen-carat gold, silver and titanium plates. The number of ablating pulses was 10000. Post-annealing of the films was carried out in atmospheric air at oven temperatures between 320 and 500 °C. The thickness of the thin layers was around 5 μm. The prepared films were granular without heat treatment or after annealing at a temperature below 340 °C. At 360 °C a crystalline, contiguous, smooth, very compact and pinhole-free thin layer was produced; a melted and re-solidified morphology was observed above 420 °C. The adhesion strength between the Teflon films and the metal substrates was determined. This could exceed 1-4 MPa depending on the treatment temperature. It was proved that the prepared Teflon layers can be suitable for prevention of contact between the human body and allergen metals and so for avoidance of metal allergy.

  12. Unpacking attitude certainty: attitude clarity and attitude correctness.

    Science.gov (United States)

    Petrocelli, John V; Tormala, Zakary L; Rucker, Derek D

    2007-01-01

    Attitude certainty has been the subject of considerable attention in the attitudes and persuasion literature. The present research identifies 2 aspects of attitude certainty and provides evidence for the distinctness of the constructs. Specifically, it is proposed that attitude certainty can be conceptualized, and empirically separated, in terms of attitude clarity (the subjective sense that one knows what one's attitude is) and attitude correctness (the subjective sense that one's attitude is correct or valid). Experiment 1 uses factor analysis and correlational data to provide evidence for viewing attitude clarity and attitude correctness as separate constructs. Experiments 2 and 3 demonstrate that attitude clarity and attitude correctness can have distinct antecedents (repeated expression and consensus feedback, respectively). Experiment 4 reveals that these constructs each play an independent role in persuasion and resistance situations.

    Full Text Available The purpose of this study is to know the teachers’ opinions in terms of multiple intelligence theory about the objectives and activities in the units of “Earth, Sun and Moon” and the “Electricity in Our Life” in the primary education 5th grade science and technology curriculum. The survey model was used in this study. The population of this study consists of 262 5th grade teachers working in the center of Malatya. The sample consists of 190 5th grade teachers who were selected randomly. Questionnaire was used to collect data that are consisted of 70 items. Teachers are asked to select one dominant intelligence type for 65 objectives and activities. To analyze the data, the background information of teachers like seniority, graduated faculty, whether or not they had in-service education were compared to teachers opinions about which intelligence area is suitable with these objectives and activities and these comparison information was given and commented with frequencies, percentages and cross tabs. Given the results of this study, about evaluating the objectives and activities in these units, taking all activities in the teaching-learning process into consideration, it is discovered that, teachers generally focus on visual, spatial, logical and mathematical intelligence areas and they think in the same way regardless of their seniority, graduated faculty, and whether or not they had in-service education about teaching-learning theories and models. Some advices are given based on the results of this study.

    Musical experience is often related to an emotional and imaginative engagement of the listener. Discourses of journalistic documentaries relate primarily to inferential knowledge systems in which the uses of background music as a communicative device become an object of epistemological critique....... By listening to different voices - primarily from four focus group interviews - the article will discuss attitudes towards musical soundtracks in documentaries, attitudes being negotiated between emotional immersion and critical reflection, with the concept of manipulation as an underlying theme. In the end......, the article will argue for the need for an acoustemological approach (Feld, 1996) to study the epistemological potential of sound in audiovisual media....

    This paper explores the erosion and problematization of ‘the organization’ as a demarcated entity. Utilizing Foucault's reflections on ‘state-phobia’ as a source of inspiration, I show how an organization-phobia has gained a hold within Organization Theory (OT). By attending to the history...... of this organization-phobia, the paper argues that OT has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming theoretically deconstructed and associated with all kinds of ills. Through this history......, organizations as distinct entities have been rendered so problematic that they have gradually come to be removed from the center of OT. The costs of this have been rather significant. Besides undermining the grounds that gave OT intellectual credibility and legitimacy to begin with, the organization-phobia...

  20. What drives the gender gap in STEM? The SAGA Science, Technology and Innovation Gender Objectives List (STI GOL) as a new approach to linking indicators to STI policies

    Energy Technology Data Exchange (ETDEWEB)

    Fernandez, E.; Schaaper, M.; Bello, A.

    2016-07-01

    There is a large imbalance in the participation of women in Science, Technology, Engineering and Mathematics (STEM) fields across all of Latin American countries despite the fact that the region has one of the highest proportions of female researchers worldwide (44% according to UIS statistics). Female researchers face persisting institutional and cultural barriers, which limit the development of their careers and constrains their access to decision-making positions. In this framework, UNESCO has launched the STEM and Gender Advancement (SAGA) project, which has for objective to address the gender gap in STEM fields in all countries at all levels of education and research as well as to promote women’s participation in science. SAGA is a global UNESCO project with the support of the Swedish Government through the Swedish International Development Cooperation Agency (Sida). One of the outcomes of this project is the SAGA Science, Technology and Innovation Gender Objectives List (STI GOL), which is an innovative tool that aids in the identification of gaps in the policy mix. Additionally, the STI GOL configures the conceptual backbone of the SAGA project, by linking gender equality STI policy instruments with indicators. By using the STI GOL, and identifying the gender gaps, policy-makers will be able to implement evidence-based policies in STEM fields. The SAGA STI GOL is a new and innovative way of contributing to the development of effective gender sensitive policies in STI fields, both in education and in the workplace. Likewise, it enables the categorization of STI policies and instruments, with the objective of identifying gaps in the policy mix and aid in the creation and design of evidence-based public policies to promote gender equality.

Based on the dynamics analysis of flexible spacecrafts, a robust maneuver control strategy is designed,and a asymmetric trapezoidal speed profile is proposed. The multi-objective optimization model of the profile planning is constructed for the large angle rapid maneuver of flexible spacecrafts, and an improved r-dominance multi-objective optimization algorithm for the planning is proposed to ensure the solution diversity and modify the expression of the decision maker's preferences. Simulation results demonstrate the effectiveness of the profile planning and the proposed optimization method.

    2013-12-01

    Full Text Available Information technology (IT has provided new means for learning delivery outside of conventional classrooms. Leveraging on IT, blended learning is an approach which takes advantage of the best that both the classroom and online learning can provide. To help institutions of higher learning (IHLs improve their understanding of how students view blended learning and formulate a strategy to successfully implement blended learning, the main objective of this paper is to examine how the attitude of students towards different learning aspects could influence their readiness for blended learning. We conceptualized six learning aspects in a research model and then collected responses from 201 full-time undergraduate students to validate the model. Analyses revealed three key findings. First, the use of technology in education was not a hindrance to the students. Second, blended learning adaptability, which was modelled as a second-order formative construct and formed by four first-order reflective constructs—attitude towards online learning, study management, online interaction, and learning flexibility—had a positive relationship with student readiness for blended learning. Third, attitude towards classroom learning had a negative relationship with student readiness for blended learning. An understanding of student attitude towards different learning aspects can be critical in the assessment of student readiness for blended learning, which is a prerequisite for successful implementation of blended learning.

    Commercially available interactive video games are commonly used in rehabilitation to aide in physical recovery from a variety of conditions and injuries, including burns. Most video games were not originally designed for rehabilitation purposes and although some games have shown therapeutic potential in burn rehabilitation, the physical demands of more recently released video games, such as Microsoft Xbox Kinect™ (Kinect) and Sony PlayStation 3 Move™ (PS Move), have not been objectively evaluated. Video game technology is constantly evolving and demonstrating different immersive qualities and interactive demands that may or may not have therapeutic potential for patients recovering from burns. This study analyzed the upper extremity motion demands of Kinect and PS Move using three-dimensional motion analysis to determine their applicability in burn rehabilitation. Thirty normal children played each video game while real-time movement of their upper extremities was measured to determine maximal excursion and amount of elevation time. Maximal shoulder flexion, shoulder abduction and elbow flexion range of motion were significantly greater while playing Kinect than the PS Move (p≤0.01). Elevation time of the arms above 120° was also significantly longer with Kinect (pgames show therapeutic potential in burn rehabilitation. Objectively quantifying the physical demands of video games commonly used in rehabilitation aides clinicians in the integration of them into practice and lays the framework for further research on their efficacy.

    Full Text Available Inclusive education serves the entire population of students at schools independent of their diverse characteristics and needs. This situation has required methodological, curricular and attitudinal changes among teachers.The objectives of this study are to evaluate teachers´ attitudes towards inclusion and the strategies used in the classroom. Furthermore this study pretends to evaluate the influence of sociodemographic variables and variables related to professional practice on these attitudes and strategies. A quantitative methodology, which included the application of the questionnaire Attitudes and practices of teachers related to inclusion, was used.The sample is formed by 82 teachers. The results indicate the presence of positive attitudes towards inclusion and a frequent use of inclusive strategies. There is a correlation between the attitudes and the use of inclusive strategies: the more positive the attitudes the more use of inclusive strategies. Professional variables have a greater impact on the attitudes and the strategies than sociodemographic variables.

  19. Formal semantics for propositional attitudes

    Directory of Open Access Journals (Sweden)

    Daniel Vanderveken

    2011-06-01

    Full Text Available Contemporary logic is confined to a few paradigmatic attitudes such as belief, knowledge, desire and intention. My purpose is to present a general model-theoretical semantics of propositional attitudes of any cognitive or volitive mode. In my view, one can recursively define the set of all psychological modes of attitudes. As Descartes anticipated, the two primitive modes are those of belief and desire. Complex modes are obtained by adding to primitive modes special cognitive and volitive ways or special propositional content or preparatory conditions. According to standard logic of attitudes (Hintikka, human agents are either perfectly rational or totally irrational. I will proceed to a finer analysis of propositional attitudes that accounts for our imperfect but minimal rationality. For that purpose I will use a non standard predicative logic according to which propositions with the same truth conditions can have different cognitive values and I will explicate subjective in addition to objective possibilities. Next I will enumerate valid laws of my general logic of propositional attitudes. At the end I will state principles according to which minimally rational agents dynamically revise attitudes of any mode.

    Full Text Available This paper describes a methodological proposal for the design, creation and evaluation of Learning Objects (LOs. This study arises from the compilation and analysis of several LO design methodologies currently used in Ibero-America. This proposal, which has been named DICREVOA, defines five different phases: analysis, design (instructional and multimedia, implementation (LO and metadata, evaluation (from the perspective of both the producer and the consumer of the LO, and publishing. The methodology focuses not only on the teaching inexperienced, but also on those having a basic understanding of the technological and educational aspects related to LO design; therefore, the study emphasizes LO design activities centered around the Kolb cycle and the use of the ExeLearning tool in order to implement the LO core. Additionally, DICREVOA was used in a case study, which demonstrates how it provides a feasible mechanism for LO design and implementation withindifferent contexts. Finally, DICREVOA, the case study to which it was applied, and the results obtained are presented.

    2016-09-01

    Full Text Available The objects of the study are as follows: rudd and goldfish, samples of food minced made of them without washing, after single and double washings. To study the organoleptic and physico-chemical parameters the conventional methods of the fishing industry have been used. At the LLC "Astrakhan fisheries" two experimental batches of minced rudd and goldfish with double washing by water using a food additive "Omfresh plus" have been made in the amount of 1.0 % by weight of the meat. The yield of washed minced food from rudd is 41.4 %, from silver carp – 41.0 %. Some decrease in water content, water-holding capacity and formalin-titratable nitrogen in minced fish after each washing step has been established. Studying the organoleptic characteristics has shown that the frozen minced briquettes are cuboids, have clean surface with the presence of minor irregularities, colour – light gray, dense texture. On physical and chemical parameters the food washed mince correspond to GOST R 55505–2013 "Frozen food fish forcemeat. Specifications". Water content is 79–82 %, sodium chloride – 0,17–0,35 %, and water-holding capacity – at over 50 %. The proven technology of manufacturing washed minced from goldfish and rudd can be put into production for the purpose of deep processing of unprofitable species of the Volga-Caspian Basin and getting washed minced food and culinary products based on it.

    Condit, Celeste M

    2010-01-01

    The existing research base on public attitudes about genetics shows that people's attitudes vary according to the specific technologies and purposes to which genetic knowledge is applied. Genetic testing is viewed highly favorably, genetically modified food is viewed with ambivalence, and cloning is viewed negatively. Attitudes are favorable for uses that maintain a perceived natural order and unfavorable for uses that are perceived to change it. Public concerns about control of genetic information and eugenics are evident, but their strength and relevance to policy preference are unclear. The pattern of attitudes can be explained by theories of attitude formation, and the existing base of information can be deepened and given more explanatory and predictive power by integrating future research into the various traditions that theorize attitude formation.

  13. Information technology and innovative drainage management practices for selenium load reduction from irrigated agriculture to provide stakeholder assurances and meet contaminant mass loading policy objectives

    Quinn, N.W.T.

    2009-10-15

    Many perceive the implementation of environmental regulatory policy, especially concerning non-point source pollution from irrigated agriculture, as being less efficient in the United States than in many other countries. This is partly a result of the stakeholder involvement process but is also a reflection of the inability to make effective use of Environmental Decision Support Systems (EDSS) to facilitate technical information exchange with stakeholders and to provide a forum for innovative ideas for controlling non-point source pollutant loading. This paper describes one of the success stories where a standardized Environmental Protection Agency (EPA) methodology was modified to better suit regulation of a trace element in agricultural subsurface drainage and information technology was developed to help guide stakeholders, provide assurances to the public and encourage innovation while improving compliance with State water quality objectives. The geographic focus of the paper is the western San Joaquin Valley where, in 1985, evapoconcentration of selenium in agricultural subsurface drainage water, diverted into large ponds within a federal wildlife refuge, caused teratogenecity in waterfowl embryos and in other sensitive wildlife species. The fallout from this environmental disaster was a concerted attempt by State and Federal water agencies to regulate non-point source loads of the trace element selenium. The complexity of selenium hydrogeochemistry, the difficulty and expense of selenium concentration monitoring and political discord between agricultural and environmental interests created challenges to the regulation process. Innovative policy and institutional constructs, supported by environmental monitoring and the web-based data management and dissemination systems, provided essential decision support, created opportunities for adaptive management and ultimately contributed to project success. The paper provides a retrospective on the contentious planning

  14. Object crowding.

    Crowding occurs when stimuli in the peripheral fields become harder to identify when flanked by other items. This phenomenon has been demonstrated extensively with simple patterns (e.g., Gabors and letters). Here, we characterize crowding for everyday objects. We presented three-item arrays of objects and letters, arranged radially and tangentially in the lower visual field. Observers identified the central target, and we measured contrast energy thresholds as a function of target-to-flanker spacing. Object crowding was similar to letter crowding in spatial extent but was much weaker. The average elevation in threshold contrast energy was in the order of 1 log unit for objects as compared to 2 log units for letters and silhouette objects. Furthermore, we examined whether the exterior and interior features of an object are differentially affected by crowding. We used a circular aperture to present or exclude the object interior. Critical spacings for these aperture and "donut" objects were similar to those of intact objects. Taken together, these findings suggest that crowding between letters and objects are essentially due to the same mechanism, which affects equally the interior and exterior features of an object. However, for objects defined with varying shades of gray, it is much easier to overcome crowding by increasing contrast.

    Abstract Our attitudes toward others influence a wide range of everyday behaviors and have been the most extensively studied concept in the history of social psychology. Yet they remain difficult to measure reliably and objectively, since both explicit and implicit measures are typically confounded by other psychological processes. We here address the feasibility of decoding incidental attitudes based on brain activations. Participants were presented with pictures of members of a Japanese idol group inside an functional magnetic resonance imaging scanner while performing an unrelated detection task, and subsequently (outside the scanner) performed an incentive-compatible choice task that revealed their attitude toward each celebrity. We used a real-world election scheme that exists for this idol group, which confirmed both strongly negative and strongly positive attitudes toward specific individuals. Whole-brain multivariate analyses (searchlight-based support vector regression) showed that activation patterns in the anterior striatum predicted each participant’s revealed attitudes (choice behavior) using leave-one-out (as well as 4-fold) cross-validation across participants. In contrast, attitude extremity (unsigned magnitude) could be decoded from a distinct region in the posterior striatum. The findings demonstrate dissociable striatal representations of valenced attitude and attitude extremity and constitute a first step toward an objective and process-pure neural measure of attitudes.

    2014-01-01

    Recent technological developments in molecular genetics facilitate the large-scale detection of inherited genetic disorders and allow an increasing number of genetic conditions to be screened for (American College of Medical Genetics 2012). This technological evolution creates the background which makes reflection necessary about the desirability to offer community-based (preconception) carrier screening in the healthcare system. A positive attitude of potential providers is vital to the success of a screening program. Therefore, the objective of this article is to elaborate a review of the attitudes of healthcare professionals toward carrier screening. Examination of existing carrier screening programs could provide such information. The literature review will be focused on the attitudes toward carrier screening for cystic fibrosis (CF). The databases Pubmed and Web of Science, as well as the interface Google Scholar, were searched using the keywords for the period 1990-2011. Studies were selected if they were published in a peer-reviewed journal in English and described the attitudes of potential providers toward carrier screening. Eleven studies were retrieved describing the attitudes toward carrier screening for CF. In total, seven studies reported attitudes toward the best time for carrier screening; four studies described opinions toward the best setting to offer CF carrier screening; six studies investigated the willingness to be involved in a carrier screening program, and in total 11 articles reported the concerns about offering carrier screening. Ten papers described a general attitude toward carrier screening. We can conclude that health care providers state willingness to be involved in a carrier screening program, but there is need for appropriate education as well as adequate support given the time constraints already present in consultation. The prospect of an increasing number of genetic disorders for which screening becomes possible, and the

    Existing research on public attitudes towards agricultural production systems is largely descriptive, abstracting from the processes through which members of the general public generate their evaluations of such systems. The present paper adopts a systems perspective on such evaluations, understanding them as embedded into a wider attitude system that consists of attitudes towards objects of different abstraction levels, ranging from personal value orientations over general socio-political attitudes to evaluations of specific characteristics of agricultural production systems. It is assumed that evaluative affect propagates through the system in such a way that the system becomes evaluatively consistent and operates as a schema for the generation of evaluative judgments. In the empirical part of the paper, the causal structure of an attitude system from which people derive their evaluations of pork production systems was modelled. The analysis was based on data from a cross-national survey involving 1931 participants from Belgium, Denmark, Germany and Poland. The survey questionnaire contained measures of personal value orientations and attitudes towards environment and nature, industrial food production, food and the environment, technological progress, animal welfare, local employment and local economy. In addition, the survey included a conjoint task by which participants' evaluations of the importance of production system attributes were measured. The data were analysed by means of causal search algorithms and structural equation models. The results suggest that evaluative judgments of the importance of pork production system attributes are generated in a schematic manner, driven by personal value orientations. The effect of personal value orientations was strong and largely unmediated by attitudes of an intermediate level of generality, suggesting that the dependent variables in the particular attitude system that was modelled here can be understood as value

  16. Visual attitude propagation for small satellites

    Science.gov (United States)

    Rawashdeh, Samir A.

    As electronics become smaller and more capable, it has become possible to conduct meaningful and sophisticated satellite missions in a small form factor. However, the capability of small satellites and the range of possible applications are limited by the capabilities of several technologies, including attitude determination and control systems. This dissertation evaluates the use of image-based visual attitude propagation as a compliment or alternative to other attitude determination technologies that are suitable for miniature satellites. The concept lies in using miniature cameras to track image features across frames and extracting the underlying rotation. The problem of visual attitude propagation as a small satellite attitude determination system is addressed from several aspects: related work, algorithm design, hardware and performance evaluation, possible applications, and on-orbit experimentation. These areas of consideration reflect the organization of this dissertation. A "stellar gyroscope" is developed, which is a visual star-based attitude propagator that uses relative motion of stars in an imager's field of view to infer the attitude changes. The device generates spacecraft relative attitude estimates in three degrees of freedom. Algorithms to perform the star detection, correspondence, and attitude propagation are presented. The Random Sample Consensus (RANSAC) approach is applied to the correspondence problem to successfully pair stars across frames while mitigating falsepositive and false-negative star detections. This approach provides tolerance to the noise levels expected in using miniature optics and no baffling, and the noise caused by radiation dose on orbit. The hardware design and algorithms are validated using test images of the night sky. The application of the stellar gyroscope as part of a CubeSat attitude determination and control system is described. The stellar gyroscope is used to augment a MEMS gyroscope attitude propagation

    Linking mobile phone technology with electronic data collection may facilitate the research experience and improve compliance. We conducted a qualitative interview study using a purposeful sample of 10 patients with asthma and two research staff. Patient diary information was collected twice a day using an electronic peak flow meter linked to a mobile phone with an interactive screen to record current asthma symptoms transmitted to, and stored in, a server. An analysis of the interview data identified key technological adjustments and support factors which would improve the application of the technology in future clinical trials. Patients and staff believed that mobile phone technology would be useful in clinical practice as well as research. Its main uses were seen as identifying poor control more quickly and facilitating communication with healthcare professionals without the need for face-to-face consultation. There was a high degree of acceptability to both patients and staff.

  20. Implicit attitudes in sexuality: gender differences.

    Science.gov (United States)

    Geer, James H; Robertson, Gloria G

    2005-12-01

    This study examined the role of gender in both implicit and explicit attitudes toward sexuality. Implicit attitudes are judgments or evaluations of social objects that are automatically activated, often without the individual's conscious awareness of the causation. In contrast, explicit attitudes are judgments or evaluations that are well established in awareness. As described in Oliver and Hyde's (1993) meta-analysis of self-report (explicit) data, women report greater negative attitudes toward sexuality than do men. In the current study, we used the Sexual Opinion Survey (SOS) developed by Fisher, Byrne, White, and Kelley (1988) to index explicit attitudes and the Implicit Association Test (IAT) developed by Greenwald, McGhee, and Schwartz (1998) to index implicit attitudes. Research has demonstrated that the IAT reveals attitudes that participants may be reluctant to express. Independent variables examined were participant gender, social acceptability of sexual words, and order of associated evaluations in the IAT (switching from positive to negative evaluations or the reverse). The IAT data revealed a significant Order x Gender interaction that showed that women had more negative implicit attitudes toward sexuality than did men. There was also a significant Order x Acceptability interaction, indicating that implicit attitudes were more strongly revealed when the sexual words used in the IAT were more socially unacceptable. As expected, on the SOS, women had more negative explicit attitudes toward sexuality. There was no significant correlation between explicit and implicit attitudes. These data suggest that at both automatic (implicit) and controlled (explicit) levels of attitudes, women harbor more negative feelings toward sex than do men.

    The object of this paper is to study the impervious surface extraction method using remote sensing imagery and monitor the spatiotemporal changing patterns of mega cities. Megacity Bombay was selected as the interesting area. Firstly, the pixel-based and object-oriented support vector machine (SVM) classification methods were used to acquire the land use/land cover (LULC) products of Bombay in 2010. Consequently, the overall accuracy (OA) and overall Kappa (OK) of the pixel-based method were 94.97% and 0.96 with a running time of 78 minutes, the OA and OK of the object-oriented method were 93.72% and 0.94 with a running time of only 17s. Additionally, OA and OK of the object-oriented method after a post-classification were improved up to 95.8% and 0.94. Then, the dynamic impervious surfaces of Bombay in the period 1973-2015 were extracted and the urbanization pattern of Bombay was analysed. Results told that both the two SVM classification methods could accomplish the impervious surface extraction, but the object-oriented method should be a better choice. Urbanization of Bombay experienced a fast extending during the past 42 years, implying a dramatically urban sprawl of mega cities in the developing countries along the One Belt and One Road (OBOR).

The objective of this study was to determine paramedic students' attitudes towards e-learning. A cross-sectional methodology was used in the form of a paperbased survey to elicit students' attitudes to e-learning using three standardised scales. Convenience sampling was used to sample a cross-section of paramedic students at five universities during semester 1 of 2009. The scales used were: the Computer Attitude Survey (CAS, the Online Learning Environment Survey (OLES, and the Attitude Toward CAI Semantic Differential Scale (ATCAISDS. There were 339 students who participated. Approximately onehalf (57.7% were female and most (76.0% were under 24 years of age. Moderate results were noted for the CAS general and education subscales. The CAS results were broadly corroborated by the OLES, although a statistically significant difference between participants preferred and actual results on the OLES Computer Usage subscale identified that participants would prefer to use computers less than they actually do. Similarly, the ATCAISDS found participants were largely ambivalent towards computers. As paramedic degree programs continue to emerge and develop, careful consideration should be given to the usability and utility of various e-learning approaches.

  7. Objective becoming

    Bradford Skow presents an original defense of the 'block universe' theory of time, often said to be a theory according to which time does not pass. Along the way, he provides in-depth discussions of alternative theories of time, including those in which there is 'robust passage' of time or 'objective becoming': presentism, the moving spotlight theory of time, the growing block theory of time, and the 'branching time' theory of time. Skow explains why the moving spotlight theory is the best of these arguments, and rebuts several popular arguments against the thesis that time passes. He surveys the problems that the special theory of relativity has been thought to raise for objective becoming, and suggests ways in which fans of objective becoming may reconcile their view with relativistic physics. The last third of the book aims to clarify and evaluate the argument that we should believe that time passes because, somehow, the passage of time is given to us in experience. He isolates three separate arguments thi...

    Full Text Available Our Earth Planet confronts the global crisis including the environmental area and its common cause, the unconscious acting of the human being and the convergent effect to the extermination of the world and the human sort. At present environmental insufficiencies are persisted related to the environmental knowledge of the Construction technician in Oscar Alberto Ortega Lara Polytechnic Institute as well as in the development of a favourable environmental attitudes establishing a contradiction in the social practice between a model wanted in the Technical and Professional Education (TPE - to graduate technicians of the Construction Family with good environmental behaviour. That’s why in this paper it is argued that the environmental attitudes of the TPE students constitute a social problem of the Science and the Technology, getting as a result that the application of the epistemology bases given, emits positive changes in their cognitive, affective and participative attitudes to the environmental situations.

    With the seriousness of the climate change threat, the European Union has invited its member states to adopt the goal of dividing by a factor 4 their greenhouse gas emissions before 2050. France has answered this invitation and requested the De Boissieu Commission to make an inventory of the means allowing to reach this goal. A first debate took place at Grenoble on November 16, 2006 about the technological and industrial consequences of such a perspective and about the necessary R and D trends to be implemented (socio-economic impacts, changes in the sectors of transportation, dwellings, space heating, lighting and air-conditioning, role of nuclear and renewable energy sources). The results of these debates are summarized in this newsletter: what is Factor 4; what are the technological, economical and social implications; the achievable changes in the transportation sector; HOMES project: optimized dwellings and buildings for energy mastery and services; role of nuclear energy in the reduction of the fossil fuels share; rise in power of renewable energy sources.

  13. Objective thermomechanics

    An irreversible thermodynamical theory of solids is presented where the kinematic quantities are defined in an automatically objective way. Namely, auxiliary elements like reference frame, reference time and reference configuration are avoided by formulating the motion of the continuum on spacetime directly, utilizing the Weyl-Matolcsi description of spacetime. This restricts the range of definable kinematic quantities heavily. Solids are distinguished from fluids by possessing not only an instantaneous metric tensor but a relaxed metric, too, that represents the natural geometric structure of the solid. The comparison of the instantaneous metric to the relaxed one is the basis of the definition of the elastic state variable, the elastic deformedness tensor. Thermal expansion is conceived as the temperature dependence of the relaxed metric. As opposed to this reversible type of change, plasticity means an irreversible change in the relaxed metric, and is describable via a plastic change rate tensor. The relat...

  14. The influence of classroom experiences on community college students self-efficacy, attitude, and future intentions

    Dawkins, Linda Mulderig

    Science and technology are an integral part of everyday life. Therefore it is necessary that the general population have some understanding and appreciation for science. Participating in activities that are science-related is one way a person could enhance their understanding and appreciation for science. According to the Theory of Planned Behavior (TPB), the attitude and self-efficacy beliefs a person holds regarding an object or activity will influence behavioral intentions (Ajzen, 1991). Therefore, if science educators can have a positive influence on their students' attitude and sense of efficacy toward science, perhaps the result will be a populace who willingly participates in science-related activities, ultimately gaining a better understanding and appreciation for science. The present study examined the relationships between the classroom environment students experienced during a ten week period of introductory chemistry and their attitudes toward chemistry (and general science), chemistry self-efficacy, and intentions to participate in chemistry-related activities in the future. The participants of this study (N = 189) were Midwestern community college students enrolled in an introductory chemistry course. The efficacy scale of the Chemistry Attitude and Experiences Questionnaire (CAEQ) developed by Dalgety, Coll, and Jones (2003) was used to measure student chemistry self-efficacy. The attitude scale used in this study consisted of the attitude toward chemistry items of CAEQ and five additional items pertaining to general science attitude. The classroom environment scale was defined by two measures: (1) instructional pedagogies and (2) teacher immediacy behaviors. The items within the instructional pedagogies and teacher immediacy measures were based on previous research that focused on identifying teaching techniques and teacher attributes that were conducive to promoting an engaging, supportive classroom environment that would promote better attitude

  18. A critique of Stephen Downes' article, "Learning Objects" -- A perspective from Bahrain

    Full Text Available With the availability of technology, hardware, and software, learning objects become fundamental to the learning process and change the way in which learning materials are designed. The vast development of technology forces both teacher and learner to modify their roles. Teachers become facilitators, while learners became active and responsible for selecting modes and styles of learning. Assuming this attitude of implementing technology in the learning process and seeking new methods of facilitating learning, universities and colleges have to adopt new techniques. One of these new techniques is the use of learning objects. Although learning objects are considered products of technology developed in the USA, Japan, and European countries, universities in the Middle East have been influenced by this development. While there are differences in the quantity and quality of these technologies available in many Middle East countries, computer applications, especially those that deploy the Internet, have now become available. Educational authorities in Middle East countries are now turning to the availability of learning objects. Let me clarify some of the issues Downes discusses in his article on learning objects, Vol. 2, No. 1 of the International Review of Research in Open and Distance Learning.

    Full Text Available Future space missions will involve satellites with great autonomy and stringent pointing precision, requiring of the Attitude Control Systems (ACS with better performance than before, which is function of the control algorithms implemented on board computers. The difficulties for developing experimental ACS test is to obtain zero gravity and torque free conditions similar to the SCA operate in space. However, prototypes for control algorithms experimental verification are fundamental for space mission success. This paper presents the parameters estimation such as inertia matrix and position of mass centre of a Satellite Attitude Control System Simulator (SACSS, using algorithms based on least square regression and least square recursive methods. Simulations have shown that both methods have estimated the system parameters with small error. However, the least square recursive methods have performance more adequate for the SACSS objectives. The SACSS platform model will be used to do experimental verification of fundamental aspects of the satellite attitude dynamics and design of different attitude control algorithm.
