Mathematical sense-making—looking for coherence between the structure of the mathematical formalism and causal or functional relations in the world—is a core component of physics expertise. Some physics education research studies have explored what mathematical sense-making looks like at the introductory physics level, while some historians and "science studies" have explored how expert physicists engage in it. What is largely missing, with a few exceptions, is theoretical and empirical work at the intermediate level—upper division physics students—especially when they are learning difficult new mathematical formalism. In this paper, we present analysis of a segment of video-recorded discussion between two students grappling with a quantum mechanics question to illustrate what mathematical sense-making can look like in quantum mechanics. We claim that mathematical sense-making is possible and productive for learning and problem solving in quantum mechanics. Mathematical sense-making in quantum mechanics is continuous in many ways with mathematical sense-making in introductory physics. However, in the context of quantum mechanics, the connections between formalism, intuitive conceptual schema, and the physical world become more compound (nested) and indirect. We illustrate these similarities and differences in part by proposing a new symbolic form, eigenvector eigenvalue, which is composed of multiple primitive symbolic forms.

Tracing changes in families who participated in the home-start parenting program: parental sense of competence as mechanism of change.

Science.gov (United States)

Deković, Maja; Asscher, Jessica J; Hermanns, Jo; Reitz, Ellen; Prinzie, Peter; van den Akker, Alithe L

2010-09-01

The present study aimed to (1) determine the long-term effectiveness of Home-Start, a preventive parenting program, and (2) test the hypothesis that changes in maternal sense of competence mediate the program's effects. Participants were 124 mothers (n = 66 intervention, n = 58 comparison). Four assessments took place during a 1-year period. Latent growth modeling showed that Home-Start enhanced growth in maternal sense of competence and supportive parenting, and led to a decrease in the use of inept discipline. Results of mediational and cross-lagged analyses were consistent with the hypothesized model: Participation in Home-Start was related to the changes in maternal sense of competence, which in turn predicted changes in parenting. The results affirm the importance of directly targeting parental sense of competence in the context of prevention work with parents.

Semantic Involvement of Initial and Final Lexical Embeddings during Sense-Making: The Advantage of Starting Late.

Science.gov (United States)

van Alphen, Petra M; van Berkum, Jos J A

2012-01-01

During spoken language interpretation, listeners rapidly relate the meaning of each individual word to what has been said before. However, spoken words often contain spurious other words, like day in daisy, or dean in sardine. Do listeners also relate the meaning of such unintended, spurious words to the prior context? We used ERPs to look for transient meaning-based N400 effects in sentences that were completely plausible at the level of words intended by the speaker, but contained an embedded word whose meaning clashed with the context. Although carrier words with an initial embedding (day in daisy) did not elicit an embedding-related N400 effect relative to matched control words without embedding, carrier words with a final embedding (dean in sardine) did elicit such an effect. Together with prior work from our lab and the results of a Shortlist B simulation, our findings suggest that listeners do semantically interpret embedded words, albeit not under all conditions. We explain the latter by assuming that the sense-making system adjusts its hypothesis for how to interpret the external input at every new syllable, in line with recent ideas of active sampling in perception.

Commercial future: making remote sensing a media event

Science.gov (United States)

Lurie, Ian

1999-12-01

The rapid growth of commercial remote sensing has made high quality digital sensing data widely available -- now, remote sensing must become and remain a strong, commercially viable industry. However, this new industry cannot survive without an educated consumer base. To access markets, remote sensing providers must make their product more accessible, both literally and figuratively: Potential customers must be able to find the data they require, when they require it, and they must understand the utility of the information available to them. The Internet and the World Wide Web offer the perfect medium to educate potential customers and to sell remote sensing data to those customers. A well-designed web presence can provide both an information center and a market place for companies offering their data for sale. A very high potential web-based market for remote sensing lies in media. News agencies, web sites, and a host of other visual media services can use remote sensing data to provide current, relevant information regarding news around the world. This paper will provide a model for promotion and sale of remote sensing data via the Internet.

Older active users of ICTs make sense of their engagement

Directory of Open Access Journals (Sweden)

Magdalena Kania-Lundholm

2017-05-01

Full Text Available Research on older people’s ICT usage tends to focus on either the ways in which they go about learning to use these technologies or the impact that ICTs have on their lives. This research seems, in other words, to take for granted that older people are ‘digital immigrants’ as the digital divide debate proposed. Research that specifically looks at the ways in which older ICT users make sense of their engagement with these technologies is still limited. This article explores therefore – through focus group interviews – how a group of older people who are active ICT users make sense of their ‘digital nativeness’. The analysis shows that the interviewees are well aware that their ICT proficiency differentiated them from their peers, which is why they make sense of their ICT usage by making reference to the issues that make them ‘exceptional’ older people. These include the fact that they have used computers for many years and therefore made ICT usage an everyday habit early on; the fact that most older people do not have the skills that they themselves have, which is why they feel the need to share them with others; and the fact that their lifelong experience means they can use these technologies in judicious ways. By bringing attention to how older active ICT users make sense of their engagement, this article contributes to the notion of the digital spectrum and the debate on the inequalities that ICT proficiency brings about. 

Making Sense of Shakespeare: a Cultural Icon for Contemporary Audiences

Directory of Open Access Journals (Sweden)

Michael Olsson

2013-11-01

Full Text Available The works of William Shakespeare are more popular in the 21st century than ever before, Why are theatre and audiences around the globe still drawn to his work? How do they make sense of these texts in ways that resonate with their cosmopolitan, contemporary audiences? This article uses the findings of a study interviewing 35 theatre professionals in Canada, Finland and the United Kingdom to explore these issues. Theoretically and methodologically, it is a bricollage, drawing on a range of approaches including Foucault’s discourse analysis, Hobsbawm’s invented traditions and Dervin’s Sense-Making to understand participants sense-making as an affective, embodied social practice. It argues that attempting to understand the significance of a major cultural icon such as Shakespeare in contemporary cosmopolitan civil society needs to recognise the many meanings, roles and significances that surround him and that this complexity makes it unlikely that any one theoretical lens will prove adequate on its own.

Making sense of global warming: Norwegians appropriating knowledge of anthropogenic climate change.

Science.gov (United States)

Ryghaug, Marianne; Sørensen, Knut Holtan; Naess, Robert

2011-11-01

This paper studies how people reason about and make sense of human-made global warming, based on ten focus group interviews with Norwegian citizens. It shows that the domestication of climate science knowledge was shaped through five sense-making devices: news media coverage of changes in nature, particularly the weather, the coverage of presumed experts' disagreement about global warming, critical attitudes towards media, observations of political inaction, and considerations with respect to everyday life. These sense-making devices allowed for ambiguous outcomes, and the paper argues four main outcomes with respect to the domestication processes: the acceptors, the tempered acceptors, the uncertain and the sceptics.

Storylines of aging with HIV: shifts toward sense making.

Beuthin, Rosanne E; Bruce, Anne; Sheilds, Laurene

2015-05-01

Aging with HIV is a new phenomenon. It is expected that by 2015, approximately half of adults living with HIV in the United States will be age 50 and older. We used narrative inquiry to explore how older adults with HIV storied their experience and made sense of aging. Over a 3.5-year period, we interviewed 5 older adults living with HIV for 13 to 24 years. In analyzing the coconstructed stories, we identify six storylines that enhance understanding and guide listening: embodiment of the illness, sense making, death and loss, secrets and stigma, identity, and seeking connection. We theorize that the degree to which one reconciles each storyline influences how well one lives with illness. We share a storied exemplar to illustrate these storylines in one participant's experience of aging with HIV. These findings emphasize how vital is telling one's illness story, because sense making happens in the telling. © The Author(s) 2014.

a perspective of institutional theory, however, the development of partnering can also be understood as a strategic intervention that has destabilized the established regulative context in which the traditional contractual mode of project governance takes place. Drawing on a historical document study and data...... from an ethnographic case study of a public partnering project, it is shown that rather than providing a well-defined alternative to the traditional form of project governance, the institutional destabilization has cultivated an organization field offering a legitimate frame for local sense making....... Thus, as a project governance mechanism, partnering emerges as a collective sense-making process directed at (re-)creating a new form of rational behaviour under changing institutional conditions....

Making Sense of Low Back Pain and Pain-Related Fear.

Science.gov (United States)

Bunzli, Samantha; Smith, Anne; Schütze, Robert; Lin, Ivan; O'Sullivan, Peter

2017-09-01

Synopsis Pain-related fear is implicated in the transition from acute to chronic low back pain and the persistence of disabling low back pain, making it a key target for physical therapy intervention. The current understanding of pain-related fear is that it is a psychopathological problem, whereby people who catastrophize about the meaning of pain become trapped in a vicious cycle of avoidance behavior, pain, and disability, as recognized in the fear-avoidance model. However, there is evidence that pain-related fear can also be seen as a common-sense response to deal with low back pain, for example, when one is told that one's back is vulnerable, degenerating, or damaged. In this instance, avoidance is a common-sense response to protect a "damaged" back. While the fear-avoidance model proposes that when someone first develops low back pain, the confrontation of normal activity in the absence of catastrophizing leads to recovery, the pathway to recovery for individuals trapped in the fear-avoidance cycle is less clear. Understanding pain-related fear from a common-sense perspective enables physical therapists to offer individuals with low back pain and high fear a pathway to recovery by altering how they make sense of their pain. Drawing on a body of published work exploring the lived experience of pain-related fear in people with low back pain, this clinical commentary illustrates how Leventhal's common-sense model may assist physical therapists to understand the broader sense-making processes involved in the fear-avoidance cycle, and how they can be altered to facilitate fear reduction by applying strategies established in the behavioral medicine literature.

Neutron visual sensing technique is one of the nondestructive visualization and image-sensing techniques. In this article, some advanced neutron visual sensing techniques are introduced. The most up-to-date high-speed neutron radiography, neutron 3D CT, high-speed scanning neutron 3D/4D CT and multi-beam neutron 4D CT techniques are included with some fundamental application results. Oil flow in a car engine was visualized by high-speed neutron radiography technique to make clear the unknown phenomena. 4D visualization of pained sand in the sand glass was reported as the demonstration of the high-speed scanning neutron 4D CT technique. The purposes of the development of these techniques are to make clear the unknown phenomena and to measure the void fraction, velocity etc. with high-speed or 3D/4D for many industrial applications.

Making Sense of Crisis: Cognitive Barriers of Learning in Critical Situations

Directory of Open Access Journals (Sweden)

Ramona PERGHEL

2013-09-01

Full Text Available This paper explores the role of cognitive issues in learning from crisis situations, in particular the managers’ mental representations of crisis and the relationship of these “maps” with the learning process through “sense-making”, as well as the possible cognitive barriers that might prevent the process of learning from crisis and thus allow the incubation of crises to develop in the company. Reviewing secondary data from the current literature, the paper focuses on the complexity of human “sense-making” and understanding the phenomena of crisis and the meaning people assign to it. Considerable attention and analysis has been done in order to assess the manner in which organizations can effectively learn to prevent crisis situations, addressing the theoretical frameworks that analyse the barriers that might occur in the learning from crisis process at an individual and group level, pointing out the need of recognition and sense-making that sometimes the current state of knowledge is not well. The paper argues that the effective organizational learning from crises requires changes in the core beliefs, values and assumptions of organizational members, which translate into sustained behavioural changes and that these changes are possible through intense cognitive processes, in particular through the way managers make sense of crisis situations.  Keywords: crisis, learning, cognitive barriers, sense-making, managers, literature review

The Netherlands is a densely populated country. Cities in the metropolitan area (Randstad) will be growing at a fast pace in the coming decades1. Cities like Amsterdam and Rotterdam are being overrun by tourists. Climate change effects are noticed in cities (heavy rains for instance). Call for circular economy rises. Traffic increases. People are more self-reliant. Public space is shared by many functions. These challenges call for smart answers, more specific and directly than ever before. Sensor data is a cornerstone of these answers. In this paper we'll discuss the approaches of Dutch initiatives using sensor data as the new language to live a happy life in our cities. Those initiatives have been bundled in a knowledge platform called "Making sense for society" 1 https://www.cbs.nl/nl-nl/nieuws/2016/37/pbl-cbs-prognose-groei-steden-zet-door (in dutch)

Ecological dynamics of continuous and categorical decision-making: the regatta start in sailing.

Araújo, Duarte; Davids, Keith; Diniz, Ana; Rocha, Luis; Santos, João Coelho; Dias, Gonçalo; Fernandes, Orlando

2015-01-01

Ecological dynamics of decision-making in the sport of sailing exemplifies emergent, conditionally coupled, co-adaptive behaviours. In this study, observation of the coupling dynamics of paired boats during competitive sailing showed that decision-making can be modelled as a self-sustained, co-adapting system of informationally coupled oscillators (boats). Bytracing the spatial-temporal displacements of the boats, time series analyses (autocorrelations, periodograms and running correlations) revealed that trajectories of match racing boats are coupled more than 88% of the time during a pre-start race, via continuous, competing co-adaptions between boats. Results showed that both the continuously selected trajectories of the sailors (12 years of age) and their categorical starting point locations were examples of emergent decisions. In this dynamical conception of decision-making behaviours, strategic positioning (categorical) and continuous displacement of a boat over the course in match-race sailing emerged as a function of interacting task, personal and environmental constraints. Results suggest how key interacting constraints could be manipulated in practice to enhance sailors' perceptual attunement to them in competition.

Why a regional approach to postgraduate water education makes sense - the WaterNet experience in Southern Africa

Science.gov (United States)

Jonker, L.; van der Zaag, P.; Gumbo, B.; Rockström, J.; Love, D.; Savenije, H. H. G.

2012-03-01

This paper reports the experience of a regional network of academic departments involved in water education that started as a project and evolved, over a period of 12 yr, into an independent network organisation. The paper pursues three objectives. First, it argues that it makes good sense to organise postgraduate education and research on water resources on a regional scale. This is because water has a transboundary dimension that poses delicate sharing questions, an approach that promotes a common understanding of what the real water-related issues are, results in future water specialists speaking a common (water) language, enhances mutual respect, and can thus be considered an investment in future peace. Second, it presents the WaterNet experience as an example that a regional approach can work and has an impact. Third, it draws three generalised lessons from the WaterNet experience. Lesson 1: For a regional capacity building network to be effective, it must have a legitimate ownership structure and a clear mandate. Lesson 2: Organising water-related training opportunities at a regional and transboundary scale makes sense - not only because knowledge resources are scattered, but also because the topic - water - has a regional and transboundary scope. Lesson 3: Jointly developing educational programmes by sharing expertise and resources requires intense intellectual management and sufficient financial means.

Making a Simple Self-Starting Electric Motor

Hong, Seok-In; Choi, Jung-In; Hong, Seok-Cheol

2009-01-01

A simple electric motor has a problem in that the current applied to the motor per se can rarely trigger its rotation. Usually such motors begin to rotate after the rotor is slightly turned by hand (i.e., manual starting). In a "self-starting" motor, the rotor starts to rotate spontaneously as soon as the current is applied. This paper describes…

Making sense of information in noisy networks: human communication, gossip, and distortion.

Information from others can be unreliable. Humans nevertheless act on such information, including gossip, to make various social calculations, thus raising the question of whether individuals can sort through social information to identify what is, in fact, true. Inspired by empirical literature on people's decision-making when considering gossip, we built an agent-based simulation model to examine how well simple decision rules could make sense of information as it propagated through a network. Our simulations revealed that a minimalistic decision-rule 'Bit-wise mode' - which compared information from multiple sources and then sought a consensus majority for each component bit within the message - was consistently the most successful at converging upon the truth. This decision rule attained high relative fitness even in maximally noisy networks, composed entirely of nodes that distorted the message. The rule was also superior to other decision rules regardless of its frequency in the population. Simulations carried out with variable agent memory constraints, different numbers of observers who initiated information propagation, and a variety of network types suggested that the single most important factor in making sense of information was the number of independent sources that agents could consult. Broadly, our model suggests that despite the distortion information is subject to in the real world, it is nevertheless possible to make sense of it based on simple Darwinian computations that integrate multiple sources.

When paranoia makes sense.

Science.gov (United States)

Kramer, Roderick M

2002-07-01

On September 11, 2001, in the space of a few horrific minutes, Americans realized the fragility of trust. The country's evident vulnerability to deadly terrorism rocked our faith in the systems we rely on for security. Our trust was shaken again only a few months later with the stunning collapse of Enron, forcing us to question many of the methods and assumptions underpinning the way we work. These two crises are obviously very different, yet both serve as reminders of the perils of trusting too much. The abiding belief that trust is a strength now seems dangerously naive. This new doubtfulness runs contrary to most management literature, which has traditionally touted trust as an organizational asset. It's an easy case to make. When there are high levels of trust, employees can fully commit themselves to the organization because they can be confident that their efforts will be recognized and rewarded. Trust also means that leaders don't have to worry so much about putting the right spin on things. They can act and speak forthrightly and focus on essentials. In short, trust is an organizational superglue. Nevertheless, two decades of research on trust and cooperation in organizations have convinced social psychologist Roderick Kramer that--despite its costs--distrust can be beneficial in the workplace. Kramer has observed that a moderate form of suspicion, which he calls prudent paranoia, can in many cases prove highly beneficial to the distrustful individual or organization. In this article, he describes situations in which prudent paranoia makes sense and shows how, when properly deployed, it can serve as a powerful morale booster--even a competitive weapon--for organizations.

Contesting nonfiction: Fourth graders making sense of words and images in science information book discussions

Science.gov (United States)

Belfatti, Monica A.

Recently developed common core standards echo calls by educators for ensuring that upper elementary students become proficient readers of informational texts. Informational texts have been theorized as causing difficulty for students because they contain linguistic and visual features different from more familiar narrative genres (Lemke, 2004). It has been argued that learning to read informational texts, particularly those with science subject matter, requires making sense of words, images, and the relationships among them (Pappas, 2006). Yet, conspicuously absent in the research are empirical studies documenting ways students make use of textual resources to build textual and conceptual understandings during classroom literacy instruction. This 10-month practitioner research study was designed to investigate the ways a group of ethnically and linguistically diverse fourth graders in one metropolitan school made sense of science information books during dialogically organized literature discussions. In this nontraditional instructional context, I wondered whether and how young students might make use of science informational text features, both words and images, in the midst of collaborative textual and conceptual inquiry. Drawing on methods of constructivist grounded theory and classroom discourse analysis, I analyzed student and teacher talk in 25 discussions of earth and life science books. Digital voice recordings and transcriptions served as the main data sources for this study. I found that, without teacher prompts or mandates to do so, fourth graders raised a wide range of textual and conceptual inquiries about words, images, scientific figures, and phenomena. In addition, my analysis yielded a typology of ways students constructed relationships between words and images within and across page openings of the information books read for their sense-making endeavors. The diversity of constructed word-image relationships aided students in raising, exploring

Camilla Groth

2013-09-01

Full Text Available This article describes an embodied way of making sense through making with the hands. We examine the potential o ftactile experience in the making process and analyse what tactile experiences mean. The study takes place in the context of an era marked by audio-visual dominance.The article presents a case study that observed and interviewed deafblind makers while they worked with clay. The findings reveal that modelling in clay resembles the visualisation process of sketching. As such, it may contribute to thinking through the hands. Language is not a self-evident communication tool for transferring tactile skills. Based on our case study, we propose the use of tactile communication in the process of transferring tactile knowledge through making with another person’s hands.

Using cognitive referents in making sense of teaching: A chemistry teacher's struggle to change assessment practices

Science.gov (United States)

Briscoe, Carol

This qualitative case study focused on the role of cognitive referents in the sense-making process of one teacher as he attempted to change his classroom science assessment. The interpretations identify cultural myths, conceptual metonymys, as well as personally constructed beliefs as referents that constrained change. The teacher's cognitive struggle to make sense of assessment and his role as assessor are linked to conflicting referents he used in varying contexts including day-to-day assessment and summative assessment settings. The results of the study suggest that cognitive referents are important influences in driving how a teacher thinks about assessment and may constrain an individual teacher's implementation of innovative practices. Accordingly, identification of referents such as myths, their associated beliefs, and metonymic conceptual models that teachers use to make sense of their actions is an important first step in developing an understanding of constraints to educational change.

Understanding uptake of complex interventions is an increasingly prominent area of research. The interplay of macro (such as changing health policy), meso (re-organisation of professional work) and micro (rationalisation of clinical care) factors upon uptake of complex interventions has rarely been explored. This study focuses on how English General Practitioners and practice nurses make sense of a complex intervention for the management of osteoarthritis, using the macro-meso-micro contextual approach and Normalisation Process Theory (NPT), specifically the construct of coherence. It is embedded in a cluster RCT comprising four control practices and four intervention practices. In order to study sense-making by professionals introduction and planning meetings (N = 14) between researchers and the practices were observed. Three group interviews were carried out with 10 GPs and 5 practice nurses after they had received training in the intervention. Transcripts were thematically analysed before comparison with NPT constructs. We found that: first, most GPs and all nurses distinguished the intervention from current ways of working. Second, from the introduction meeting to the completion of the training the purpose of the intervention increased in clarity. Third, GPs varied in their understanding of their remit, while the practice nurses felt that the intervention builds on their holistic care approach. Fourth, the intervention was valued by practice nurses as it strengthened their expert status. GPs saw its value as work substitution, but felt that a positive conceptualisation of OA enhanced the consultation. When introducing new interventions in healthcare settings the interaction between macro, meso and micro factors, as well as the means of engaging new clinical practices and their sense-making by clinicians needs to be considered.

The role of sports in making sense of the process of growing old.

Science.gov (United States)

Eman, Josefin

2012-12-01

Drawing on interviews with 22 athletically active old men and women, the study explores whether and how the practice of sports can affect old adults' processes of sense-making about old age and the process of growing old in ways that challenge dominant constructions about old age. Thereto, the study will explore the possible impact of gender in this process. The results show that men and women who continue to practice competitive sports into old age make sense of the process of growing old by focusing primarily on their physical abilities, at least in the context of sports. This focus on capability age allows them partly, although not completely, to challenge the usual thinking about old age and the process of growing old. Copyright © 2012 Elsevier Inc.

Holistic aspects of children's ways of understanding in making sense of genetics

Science.gov (United States)

Huang, Hui-Ju

The study examined the nature of how children make sense of phenomena in the area of genetics and inheritance. I proposed the phrase, way of understanding to capture a unified entity which children use to make sense of phenomena. The methodology was semi-structured probing interviews with six sixth grade students. Seven specific ways of understanding were discussed in the results section. Overall, the study described and discovered children's ways of understanding in terms of five aspects: cognitive aspects, affective aspects, social aspects, playfulness, and mode of awareness. Students' propositional knowledge, a holistic view of looking at how people resemble each other, syntactic knowledge, and an extension of rational explanations belonged to the cognitive aspects. Four categories of affective expressions were: an enjoyment of thinking and learning, a special feeling about the instructional activity, a deep personal involvement, and an anxiety in finding correct answers. Two types of social context were identified, one had somewhat of a connection to the science world, and the other did not have much of an scientific tie. The playfulness and the mode of awareness were two emerging aspects through the study. The playfulness represented the spontaneity, freedom, and sense of fun associated with the social interaction activity, such as the playfulness in expressing ideas to others. The modes of awareness included two types of metacognition, one was a conscious reflection on one's cognitive abilities, and the other was a continuous process of monitoring knowledge. In addition, the importance of considering language aspect in science learning was an emerging issue. Students' talking about genetics was embedded in the larger framework of social relationships and social institutions. Their social identify might influence the development of concepts, ways of talking and science learning. The study reflects the richness of children's sense-making processes

Does Visualization Matter? The Role of Interactive Data Visualization to Make Sense of Information

2018-05-01

Full Text Available As part of business analytics (BA technologies, reporting and visualization play essential roles in mitigating users’ limitations (i.e., being inexperienced, having limited knowledge, and relying on simplified information. Reporting and visualization can potentially enhance users’ sense-making, thus permitting them to focus more on the information’s message rather than numerical analysis. To better understand the role of reporting and visualization in a contextualized environment, we investigate using interactive data visualization (IDV within accounting. We aim to understand whether IDV can help enhance non-professional investors’ ability to make sense of foundational financial statement analyses. This study conducted an experiment using a sample of 324 nonprofessional investors. Our findings indicate that nonprofessional investors who use IDV are more heuristically adept than non-professional investors who use non-IDV. These findings enrich the theoretical understanding of business analytics’ use in accounting decision making. The results of this study also suggest several practical courses of action, such as promoting wider use of IDV and making affordable IDV more broadly available, particularly for non-professional investors.

Full Text Available This article presents the findings from a qualitative study of the German Wikipedia community, focusing on how people engaged with Wikipedia make sense of norms, collaborative practices and means of regulation within the community. The study highlights the strong focus on the quality of the end-product (the encyclopedia in the German community, stressing that article quality is seen as more important than the wiki-process as such. As the community has grown, an increasing number of rules and mechanisms have been deployed to resolve various issues and conflicts, however the interviewees do not perceive Wikipedia as being bureaucratic, but rather describe it as a “rule-governed anarchy”. The findings suggest that people contribute for a variety of reasons, yet point to reactions from and interactions with fellow Wikipedians as one of the strongest motivational drivers for participation.

Uncertainties and insufficiencies: making sense of climate adaption

Energy Technology Data Exchange (ETDEWEB)

Toesse, Sunniva Eikeland

2012-11-01

The scientist papers show, first, that climate scientists are concerned about the relevance of their research and engage in practices, even though they may, in a sense, be criticized for taking the relevance for granted. They work hard to communicate their research, even this proves uncomfortable for them personally. Secondly, these first two papers have displayed a potential challenge for climate science communication and translation: climate skeptics. The scientists' fear is that people will be confused by the climate skeptics' misleading messages about the state of climate research. A related concern may be whether the way climate scientists shape their communication efforts to avoid 'sceptic attacks', in some way inhibit translation of climate knowledge? The user papers, on the other hand, show that to potential users of climate science knowledge, the knowledge is not obviously relevant. Furthermore, there are many factors - existing institutional context, professional identities and ideas about science and climate science, and aspects of the available science information - that shape the way in which evaluate relevance. Furthermore, scientists are not particularly central in these evaluations. There is, thus, an asymmetry between the scientist's engagement with relevance and the way users evaluate the relevance of climate science knowledge. How can we make sense of this? (Author)

Sure start: voices of the 'hard-to-reach'.

Science.gov (United States)

Coe, C; Gibson, A; Spencer, N; Stuttaford, M

2008-07-01

This research aimed to look in depth at the factors affecting the ability of four Sure Start local programmes, based in a multicultural Midlands city, to engage with 'hard-to-reach' populations. A variety of research strategies and methods were employed. Geographical information systems, participatory research methods and interviews were used in order to understand the extent of the challenge, and hear first hand, why parents may not get involved with Sure Start. The mapping exercise involved collation and mapping of postcode data with respect to boundaries and potential and actual users of Sure Start services. This made possible the identification of any geographical patterning in the distribution of service users and non-users. Participatory research methods were used with parents, enabling them to conduct short interviews within their own communities and make sense of the data collected. Interviews were also conducted with 70 parents across the city, recruited through local schools. The results indicate that parental decisions regarding Sure Start are the product of a complex interaction between numerous factors which may act as either barriers or facilitators to service utilization. The results suggest that a multi-method approach to data collection is useful and appropriate in gaining access to those parents who are non-users of the Sure Start services and enabling their voices to be heard. These findings offer some explanations and insight into the apparent ambivalent attitudes of some families toward Sure Start services. Implications for future practice are discussed.

The Integration of Remote-Sensing Detection Techniques into the Operational Decision-Making of Marine Oil Spills

Science.gov (United States)

Garron, J.; Trainor, S.

2017-12-01

Remotely-sensed data collected from satellites, airplanes and unmanned aerial systems can be used in marine oil spills to identify the overall footprint, estimate fate and transport, and to identify resources at risk. Mandates for the use of best available technology exists for addressing marine oil spills under the jurisdiction of the USCG (33 CFR 155.1050), though clear pathways to familiarization of these technologies during a marine oil spill, or more importantly, between marine oil spills, does not. Similarly, remote-sensing scientists continue to experiment with highly tuned oil detection, fate and transport techniques that can benefit decision-making during a marine oil spill response, but the process of translating these prototypical tools to operational information remains undefined, leading most researchers to describe the "potential" of these new tools in an operational setting rather than their actual use, and decision-makers relying on traditional field observational methods. Arctic marine oil spills are no different in their mandates and the remote-sensing research undertaken, but are unique via the dark, cold, remote, infrastructure-free environment in which they can occur. These conditions increase the reliance of decision-makers in an Arctic oil spill on remotely-sensed data and tools for their manipulation. In the absence of another large-scale oil spill in the US, and limited literature on the subject, this study was undertaken to understand how remotely-sensed data and tools are being used in the Incident Command System of a marine oil spill now, with an emphasis on Arctic implementation. Interviews, oil spill scenario/drill observations and marine oil spill after action reports were collected and analyzed to determine the current state of remote-sensing data use for decision-making during a marine oil spill, and to define a set of recommendations for the process of integrating new remote-sensing tools and information in future oil spill

Sensors for the Senses: Meaning-making via self-active entertainment experiences

Full Text Available In his ACM Computers in Entertainment article, titled "Artist and Audience: Emerging the Nano-entertainment experience", the author posited on how Inhabited Information Spaces, created as core catalyst of research, may be questioned as a multisensory future virtual work of art. This themed Human-Computer Interaction for Entertainment contribution for the EAI INTETAIN 2015 conference builds upon the earlier work by questioning meaning making from such self-active entertainment experiences. Contextually, self-active relates to actor empowerment via ICT, whilst entertainment refers to HCI paradigms that are fun, engaging, and enjoyable. Conceptualizing, designing and realizing alternative digital media entertainment situations in stage performance, interactive installations and exhibitions at leading Museums for Modern Art, National and International major events, contributed to development of a sensor-based system conceived as a platform to investigate meaning making having societal impact beyond art. The system involves arrays of selectable sensor profiles mixed and matched according to requirements. Sensing of human input can be through worn (biosignal e.g. EEG, ECG, EMG, GSR, held, and/or non-worn sensors (volumetric, linear and planar interface profiles. Mapping of sourced human data is to a variety of digital content including art-based (music making, digital painting, lighting effects, video games, Virtual Reality and robotic devices. System adaptability promotes participant profile matching e.g. according to desired outcome. All ages and abilities are potential users. Preceding the commonly known camera-based game controllers such as EyeToy, Wii, and Kinect; the SoundScapes Virtual Interactive Space system has been used in institutes, hospitals and clinics to empower people with impairment to unconsciously push their limits of functionality via creative and playful expression.

Human-machine analytics for closed-loop sense-making in time-dominant cyber defense problems

Henry, Matthew H.

2017-05-01

Many defense problems are time-dominant: attacks progress at speeds that outpace human-centric systems designed for monitoring and response. Despite this shortcoming, these well-honed and ostensibly reliable systems pervade most domains, including cyberspace. The argument that often prevails when considering the automation of defense is that while technological systems are suitable for simple, well-defined tasks, only humans possess sufficiently nuanced understanding of problems to act appropriately under complicated circumstances. While this perspective is founded in verifiable truths, it does not account for a middle ground in which human-managed technological capabilities extend well into the territory of complex reasoning, thereby automating more nuanced sense-making and dramatically increasing the speed at which it can be applied. Snort1 and platforms like it enable humans to build, refine, and deploy sense-making tools for network defense. Shortcomings of these platforms include a reliance on rule-based logic, which confounds analyst knowledge of how bad actors behave with the means by which bad behaviors can be detected, and a lack of feedback-informed automation of sensor deployment. We propose an approach in which human-specified computational models hypothesize bad behaviors independent of indicators and then allocate sensors to estimate and forecast the state of an intrusion. State estimates and forecasts inform the proactive deployment of additional sensors and detection logic, thereby closing the sense-making loop. All the while, humans are on the loop, rather than in it, permitting nuanced management of fast-acting automated measurement, detection, and inference engines. This paper motivates and conceptualizes analytics to facilitate this human-machine partnership.

Making sense of (exceptional) causal relations. A cross-cultural and cross-linguistic study.

Le Guen, Olivier; Samland, Jana; Friedrich, Thomas; Hanus, Daniel; Brown, Penelope

2015-01-01

In order to make sense of the world, humans tend to see causation almost everywhere. Although most causal relations may seem straightforward, they are not always construed in the same way cross-culturally. In this study, we investigate concepts of "chance," "coincidence," or "randomness" that refer to assumed relations between intention, action, and outcome in situations, and we ask how people from different cultures make sense of such non-law-like connections. Based on a framework proposed by Alicke (2000), we administered a task that aims to be a neutral tool for investigating causal construals cross-culturally and cross-linguistically. Members of four different cultural groups, rural Mayan Yucatec and Tseltal speakers from Mexico and urban students from Mexico and Germany, were presented with a set of scenarios involving various types of causal and non-causal relations and were asked to explain the described events. Three links varied as to whether they were present or not in the scenarios: Intention-to-Action, Action-to-Outcome, and Intention-to-Outcome. Our results show that causality is recognized in all four cultural groups. However, how causality and especially non-law-like relations are interpreted depends on the type of links, the cultural background and the language used. In all three groups, Action-to-Outcome is the decisive link for recognizing causality. Despite the fact that the two Mayan groups share similar cultural backgrounds, they display different ideologies regarding concepts of non-law-like relations. The data suggests that the concept of "chance" is not universal, but seems to be an explanation that only some cultural groups draw on to make sense of specific situations. Of particular importance is the existence of linguistic concepts in each language that trigger ideas of causality in the responses from each cultural group.

Making sense of the Sense Model: translation priming with Japanese-English bilinguals

OpenAIRE

Allen, David; Conklin, Kathy; Van Heuven, Walter J.B.

2015-01-01

Many studies have reported that first language (L1) translation primes speed responses to second language (L2) targets, whereas L2 translation primes generally do not speed up responses to L1 targets in lexical decision. According to the Sense Model (Finkbeiner, Forster, Nicol & Nakamura, 2004) this asymmetry is due to the proportion of senses activated by the prime. Because L2 primes activate only a subset of the L1 translations senses, priming is not observed. In this study we test the pred...

Autophagy and its effects: making sense of double-edged swords.

Autophagy is the mechanism by which cellular material is delivered to lysosomes and degraded. This process has become a major focus of biological and biomedical research with thousands of papers published each year and rapidly growing appreciation that autophagy affects many normal and pathological processes. However, as we learn more about this evolutionarily ancient process, we are discovering that autophagy's effects may work for both the good and the bad of an organism. Here, I discuss some of these context-dependent findings and how, as we make sense of them, we can try to apply our knowledge for practical purposes.

Unplanned dialysis start (UPS) leads to worse clinical outcomes than planned start, and only a minority of patients ever receive education on this topic and are able to make a modality choice, particularly for home dialysis. This study aimed to determine the predictive factors for patients receiving education, making a decision, and receiving their preferred modality choice in UPS patients following a UPS educational program (UPS-EP). The Offering Patients Therapy Options in Unplanned Start (OPTiONS) study examined the impact of the implementation of a specific UPS-EP, including decision support tools and pathway improvement on dialysis modality choice. Linear regression models were used to examine the factors predicting three key steps: referral and receipt of UPS-EP, modality decision making, and actual delivery of preferred modality choice. A simple economic assessment was performed to examine the potential benefit of implementing UPS-EP in terms of dialysis costs. The majority of UPS patients could receive UPS-EP (214/270 patients) and were able to make a decision (177/214), although not all patients received their preferred choice (159/177). Regression analysis demonstrated that the initial dialysis modality was a predictive factor for referral and receipt of UPS-EP and modality decision making. In contrast, age was a predictor for referral and receipt of UPS-EP only, and comorbidity was not a predictor for any step, except for myocardial infarction, which was a weak predictor for lower likelihood of receiving preferred modality. Country practices predicted UPS-EP receipt and decision making. Economic analysis demonstrated the potential benefit of UPS-EP implementation because dialysis modality costs were associated with modality distribution driven by patient preference. Education and decision support can allow UPS patients to understand their options and choose dialysis modality, and attention needs to be focused on ensuring equity of access to educational

Beyond Epistemological Deficits: Dynamic explanations of engineering students' difficulties with mathematical sense-making

Science.gov (United States)

Gupta, Ayush; Elby, Andrew

2011-12-01

Researchers have argued against deficit-based explanations of students' difficulties with mathematical sense-making, pointing instead to factors such as epistemology. Students' beliefs about knowledge and learning can hinder the activation and integration of productive knowledge they have. Such explanations, however, risk falling into a 'deficit trap'-substituting a concepts/skills deficit with an epistemological one. Our interview-based case study of a freshman engineering major, 'Jim,' explains his difficulty solving a physics problem (on hydrostatic pressure) in terms of his epistemology, but avoids a deficit trap by modeling the dynamics of his epistemological stabilities and shifts in terms of fine-grained cognitive elements that include the seeds of epistemological expertise. Specifically, during a problem-solving episode in the interview, Jim reaches and sticks with an incorrect answer that violates common sense. We show that Jim has all the mathematical skills and physics knowledge he would need to resolve the contradiction. We argue that his difficulty doing so stems in part from his epistemological views that (i) physics equations are much more trustworthy than everyday reasoning, and (ii) physics equations do not express meaning that tractably connects to common sense. For these reasons, he does not view reconciling between common sense and formalism as either necessary or plausible to accomplish. But Jim's in-the-moment shift to a more sophisticated epistemological stance highlights the seeds of epistemological expertise that were present all along: he does see common sense as connected to formalism (though not always tractably so), and in some circumstances, this connection is both salient and valued.

Making Sense of Gov 2.0 Strategies: “No Citizens, No Party”

Directory of Open Access Journals (Sweden)

Enrico Ferro

2010-04-01

Full Text Available One of the main factors contributing to the limited impact of eParticipation projects is the presence of a high level of social complexity that has been identified by Macintosh as one of the five challenges in the implementation of eParticipation practices. How to make sense of social complexity is still an open issue as well as the way governments can take benefit from the wealth of information that is already available on their constituencies’ collective behaviour. In this paper, we contend that the presence of a considerable variance in terms of political interests, educational level and technological skills makes it very difficult to design workable and effective systems to support participation. A modular strategy is then recommended requiring policy designers to make a step towards citizens rather than expecting the citizenry to move their content production activity onto the “official” spaces created for ad hoc participation.

Hypothalamic glucose sensing: making ends meet

Directory of Open Access Journals (Sweden)

Vanessa eRouth

2014-12-01

Full Text Available The neuroendocrine system governs essential survival and homeostatic functions. For example, growth is needed for development. Thermoregulation maintains optimal core temperature in a changing environment. Reproduction ensures species survival. Stress and immune responses enable an organism to overcome external and internal threats. The circadian system regulates arousal and sleep such that vegetative and active functions do not overlap. All of these functions require a significant portion of the body’s energy. As the integrator of the neuroendocrine system, the hypothalamus carefully assesses the energy status of the body in order to appropriately partition resources to provide for each system without compromising the others. While doing so the hypothalamus must ensure that adequate glucose levels are preserved for brain function since glucose is the primary fuel of the brain. To this end, the hypothalamus contains specialized glucose sensing neurons which are scattered throughout the nuclei controlling distinct neuroendocrine functions. We hypothesize that these neurons play a key role in enabling the hypothalamus to partition energy to meet these peripheral survival needs without endangering the brain’s glucose supply. The goal of this review is to describe the varied mechanisms underlying glucose sensing in neurons within discrete hypothalamic nuclei. We will then evaluate the way in which peripheral energy status regulates glucose sensitivity. For example, during energy deficit such as fasting specific hypothalamic glucose sensing neurons become sensitized to decreased glucose. This increases the gain of the information relay when glucose availability is a greater concern for the brain. Finally, changes in glucose sensitivity under pathological conditions (e.g., recurrent insulin-hypoglycemia, diabetes will be addressed. The overall goal of this review is to place glucose sensing neurons within the context of hypothalamic control of

Carbon for sensing devices

CERN Document Server

Tagliaferro, Alberto

2015-01-01

This book reveals why carbon is playing such an increasingly prominent role as a sensing material. The various steps that transform a raw material in a sensing device are thoroughly presented and critically discussed.  The authors deal with all aspects of carbon-based sensors, starting from the various hybridization and allotropes of carbon, with specific focus on micro and nanosized carbons (e.g., carbon nanotubes, graphene) and their growth processes. The discussion then moves to the role of functionalization and the different routes to achieve it. Finally, a number of sensing applications in various fields are presented, highlighting the connection with the basic properties of the various carbon allotropes.  Readers will benefit from this book’s bottom-up approach, which starts from the local bonding in carbon solids and ends with sensing applications, linking the local hybridization of carbon atoms and its modification by functionalization to specific device performance. This book is a must-have in th...

Cassin, Bryce R; Barach, Paul R

2012-02-01

This article discusses the limitations of root cause analysis (RCA) for surgical adverse events. Making sense of adverse events involves an appreciation of the unique features in a problematic situation, which resist generalization to other contexts. The top priority of adverse event investigations must be to inform the design of systems that help clinicians to adapt and respond effectively in real time to undesirable combinations of design, performance, and circumstance. RCAs can create opportunities in the clinical workplace for clinicians to reflect on local barriers and identify enablers of safe and reliable outcomes. Copyright © 2012 Elsevier Inc.

Suarez, Enrique; Otero, Valerie

2013-01-01

Despite the extensive body of research that supports scientific inquiry and argumentation as cornerstones of physics learning, these strategies continue to be virtually absent in most classrooms, especially those that involve students who are learning English as a second language. This study presents results from an investigation of 3rd grade students' discourse about how length and tension affect the sound produced by a string. These students came from a variety of language backgrounds, and all were learning English as a second language. Our results demonstrate varying levels, and uses, of experiential, imaginative, and mechanistic reasoning strategies. Using specific examples from students' discourse, we will demonstrate some of the productive aspects of working within multiple language frameworks for making sense of physics. Conjectures will be made about how to utilize physics as a context for English Language Learners to further conceptual understanding, while developing their competence in the English language.

Beyond public acceptance of energy infrastructure: How citizens make sense and form reactions by enacting networks of entities in infrastructure development

International Nuclear Information System (INIS)

Aaen, Sara Bjørn; Kerndrup, Søren; Lyhne, Ivar

2016-01-01

This article adds to the growing insight into public acceptance by presenting a novel approach to how citizens make sense of new energy infrastructure. We claim that to understand public acceptance, we need to go beyond the current thinking of citizens framed as passive respondents to proposed projects, and instead view infrastructure projects as enacted by citizens in their local settings. We propose a combination of sensemaking theory and actor–network theory that allows insight into how citizens enact entities from experiences and surroundings in order to create meaning and form a reaction to new infrastructure projects. Empirically, we analyze how four citizens make sense of an electricity cable project through a conversation process with a representative from the infrastructure developer. Interestingly, the formal participation process and the materiality of the cable play minor roles in citizens' sensemaking process. We conclude that insight into the way citizens are making sense of energy infrastructure processes can improve and help to overcome shortcomings in the current thinking about public acceptance and public participation. - Highlights: •Attention to citizens' sensemaking enables greater insight into the decision-making process. •A combination of sensemaking and actor-network theory (ANT) is relevant for studies of public acceptance. •Sensemaking explains why citizens facing similar situations act differently. •Complexity of citizens' sensemaking challenges the predictability of processes.

Dye, T.

2015-12-01

Air pollution in many parts of the world is harming millions of people, shortening lives, and taking a toll on our ecosystem. Cities in India, China, and even the United States frequently exceed air quality standards. The use of localized data is a powerful enhancement to regulatory monitoring site data. Learning about air quality at a local level is a powerful driver for change. The Kids Making Sense program unites Science, Technology, Engineering, and Mathematics (STEM) education with a complete measurement and environmental education system that teaches youth about air pollution and empowers them to drive positive change in their communities. With this program, youth learn about particle pollution, its sources, and health effects. A half-day lecture is followed by hands-on activity using handheld air sensors paired with an app on smartphones. Students make measurements around schools to discover pollution sources and cleaner areas. Next, the data they collect are crowdsourced on a website for guided discussion and data interpretation. This program meets Next Generation Science Standards, encourages project-based learning and deep understanding of applied science, and allows students to practice science like real scientists. The program has been successfully implemented in several schools in the United States and Asia, including New York City, San Francisco, Los Angeles, and Sacramento in the United States, and Taipei and Taichung in Taiwan. During this talk, we'll provide an overview of the program, discuss some of the challenges, and lay out the next steps for Kids Making Sense.

Making sense of climate change risks and responses at the community level: A cultural-political lens

Directory of Open Access Journals (Sweden)

Ainka A. Granderson

2014-01-01

Full Text Available How to better assess, communicate and respond to risks from climate change at the community level have emerged as key questions within climate risk management. Recent research to address these questions centres largely on psychological factors, exploring how cognition and emotion lead to biases in risk assessment. Yet, making sense of climate change and its responses at the community level demands attention to the cultural and political processes that shape how risk is conceived, prioritized and managed. I review the emergent literature on risk perceptions and responses to climate change using a cultural-political lens. This lens highlights how knowledge, meaning and power are produced and negotiated across multiple stakeholders at the community level. It draws attention to the different ways of constructing climate change risks and suggests an array of responses at the community level. It further illustrates how different constructions of risk intersect with agency and power to shape the capacity for response and collective action. What matters are whose constructions of risk, and whose responses, count in decision-making. I argue for greater engagement with the interpretive social sciences in research, practice and policy. The interpretive social sciences offer theories and tools for capturing and problematising the ways of knowing, sense-making and mobilising around risks from climate change. I also highlight the importance of participatory approaches in incorporating the multiplicity of interests at the community level into climate risk management in fair, transparent and culturally appropriate ways.

Using "Making Sense of Climate Science Denial" MOOC videos in a college course

Science.gov (United States)

Schuenemann, K. C.; Cook, J.

2015-12-01

The Massive Open Online Course (MOOC) "Denial101x: Making Sense of Climate Science Denial" teaches students to make sense of the science and respond to climate change denial. The course is made up of a series of short, myth-debunking lecture videos that can be strategically used in college courses. The videos and the visuals within have proven a great resource for an introductory college level climate change course. Methods for using the videos in both online and in-classroom courses will be presented, as well as student reactions and learning from the videos. The videos introduce and explain a climate science topic, then paraphrase a common climate change myth, explain why the myth is wrong by identifying the characteristic of climate denial used, and concludes by reinforcing the correct science. By focusing on common myths, the MOOC has made an archive of videos that can be used by anyone in need of a 5-minute response to debunk a myth. By also highlighting five characteristics of climate denial: fake experts, logical fallacies, impossible expectations, cherry picking, and conspiracy theories (FLICC), the videos also teach the viewer the skills they need to critically examine myths they may encounter in the real world on a variety of topics. The videos also include a series of expert scientist interviews that can be used to drive home points, as well as put some faces to the science. These videos are freely available outside of the MOOC and can be found under the relevant "Most used climate myths" section on the skepticalscience.com webpage, as well as directly on YouTube.

Making sense of adolescent decision-making: challenge and reality.

Science.gov (United States)

Unguru, Yoram

2011-08-01

Few topics in pediatric bioethics are as vexing as decision-making. Decision-making in pediatrics presents challenges for children, parents, and physicians alike. The related, yet distinct, concepts of assent and consent are central to pediatric decision-making. Although informed consent is largely regarded as a worthwhile adult principle, assent has been, and continues to be, mired in debate. Controversial subjects include a meaningful definition of assent; how old children should be to assent; who should be included in the assent process; parental permission; how to resolve disputes between children and their parents; the relationship between assent and consent; the quantity and quality of information to disclose to children and their families; how much and what information children desire and need; the necessity and methods for assessing both children's understanding of disclosed information and of the assent process itself; reconciling ethical and legal attitudes toward assent; and finally, an effective, practical, and realistically applicable decision-making model.

Data Access Services that Make Remote Sensing Data Easier to Use

Science.gov (United States)

Lynnes, Christopher

2010-01-01

This slide presentation reviews some of the processes that NASA uses to make the remote sensing data easy to use over the World Wide Web. This work involves much research into data formats, geolocation structures and quality indicators, often to be followed by coding a preprocessing program. Only then are the data usable within the analysis tool of choice. The Goddard Earth Sciences Data and Information Services Center is deploying a variety of data access services that are designed to dramatically shorten the time consumed in the data preparation step. On-the-fly conversion to the standard network Common Data Form (netCDF) format with Climate-Forecast (CF) conventions imposes a standard coordinate system framework that makes data instantly readable through several tools, such as the Integrated Data Viewer, Gridded Analysis and Display System, Panoply and Ferret. A similar benefit is achieved by serving data through the Open Source Project for a Network Data Access Protocol (OPeNDAP), which also provides subsetting. The Data Quality Screening Service goes a step further in filtering out data points based on quality control flags, based on science team recommendations or user-specified criteria. Further still is the Giovanni online analysis system which goes beyond handling formatting and quality to provide visualization and basic statistics of the data. This general approach of automating the preparation steps has the important added benefit of enabling use of the data by non-human users (i.e., computer programs), which often make sub-optimal use of the available data due to the need to hard-code data preparation on the client side.

Ounaies, Zoubeida (Inventor); Park, Cheol (Inventor); Harrison, Joycelyn S. (Inventor); Holloway, Nancy M. (Inventor); Draughon, Gregory K. (Inventor)

2009-01-01

An electroactive sensing or actuating material comprises a composite made from a polymer with polarizable moieties and an effective amount of carbon nanotubes incorporated in the polymer for a predetermined electromechanical operation of the composite when such composite is affected by an external stimulus. In another embodiment, the composite comprises a, third component of micro -sized to nano-sized particles of an electroactive ceramic that is also incorporated in the polymer matrix. The method for making the three-phase composite comprises either incorporating the carbon nanotubes in the polymer matrix before incorporation of the particles of ceramic or mixing the carbon nanotubes and particles of ceramic together in a solution before incorporation in the polymer matrix.

Realism and Impartiality: Making Sustainability Effective in Decision-Making.

Science.gov (United States)

Bastons, Miquel; Armengou, Jaume

2017-08-01

There is both individual and collective widespread concern in society about the impact of human activity and the effects of our decisions on the physical and social environment. This concern is included within the idea of sustainability. The meaning of the concept is still ambiguous and its practical effectiveness disputed. Like many other authors, this article uses as a starting point the definition proposed by the World Commission on Environment and Development (Our common future, Oxford University Press, Oxford, 1987), considering it to be a proposal for changing the assessment of the effects of decisions, from at least two perspectives: (1) what effects we should consider and (2) how we should assess them. Based on this double perspective, sustainability is explored as a method for decision-making which both expands the assessment of the consequences, and also provides an objective criterion for such assessment. It will be argued that the idea of sustainability, seen from this perspective, brings to decision-making two qualities which had been partially lost: realism and impartiality. In turn, the criteria for realism and impartiality in decision-making can be used to identify the limitations of some partial approaches to sustainability, which suffer from insufficient realism (emotional altruism), insufficient impartiality (tactical altruism) or both phenomena at once (egoism). The article concludes by demonstrating how realism and impartiality provide the basis for a new form of sustainable decision-making (ethical sustainability), which is dependent on the development of two moral virtues, prudence and benevolence, and which brings practical effectiveness and ethical sense to the concept of sustainability.

Teachers' sense-making of curriculum structures and its impact on the implementation of an innovative reform-based science curriculum

Science.gov (United States)

Beckford-Smart, Meredith

This study discusses the social interactions involved in teachers' enactment and use of new science curricula. The teachers studied participated in the LiFE program, a university-school partnership, which is an inquiry based science and nutrition education program. In this program fifth and sixth grade students learned science through the study of food. The program used the study of food and food systems to teach life sciences and nutrition through inquiry based studies. Through the partnership teachers received professional development which aimed to deepen their conceptual understandings of life science and develop skills in implementing inquiry-base teaching. Using qualitative research methods of ethnography and narrative inquiry to study teachers' sense-making of messages from curriculum structures, the intention was to explore how teachers' sense-making of these structures guided their classroom practices. Two research questions were addressed: (a) How do teachers make sense of curriculum given their perceptions, their school context and their curricular context; (b) What influence do their identities as science teachers/learners have on their enactment of an innovative science curriculum. I used comparative analysis to examine teacher's beliefs and identities as teachers/learners. In the process of studying these teachers an understanding of how teachers' stories and identities shape their use and enactment of science curriculum came to light. The initial analysis revealed four distinct teacher identities: (a) social responsibility teacher/learner; (b) experiential teacher/learner; (c) supportive institution teacher/learner; and (d) turning point teacher. Besides these distinct teacher identities three cross cutting themes emerged: (a) creating environments conducive to their teaching visions; (b) empowering student through science teaching; and (c) dealing with the uncertainty of teaching. The information gathered from this study will illuminate how these

Making sense of gender from digital game play in three-year-old children’s everyday lives: An ethnographic case study

Directory of Open Access Journals (Sweden)

Youn Jung Huh

2015-06-01

Full Text Available This study explores very young children performing and talking about game characters in their everyday life. In this study, young children’s digital game play is considered as a hybrid and complex site for the children to meet popular culture and their everyday family experiences. This article represents a case study of six three-year-old children and their families, which combines ethnographic methods (spending time with the families, being a participant observer and critical perspectives analysis with Bakhtinian perspectives to construct analyses that have the potential to understand how young children make sense of their everyday roles as a boy or a girl through their game play. This study shows that young children do not directly receive ideological messages from the game media, but they make sense of the messages by decoding and interpreting the game media based on their own theories of everyday life.

Scoring fast-start climate finance: leaders and laggards in transparency

Energy Technology Data Exchange (ETDEWEB)

Ciplet, David; Roberts, J. Timmons [Brown University (United States); Stadelmann, Martin [University of Zurich (Switzerland); Huq, Saleemul; Chandani, Achala

2011-09-15

In 2009, developed countries pledged US$30 billion of 'fast-start climate finance' — new and additional funding, with 'balanced' allocation between mitigation and adaptation, to be provided during 2010–12. The need for transparency in how these promises are fulfilled is plain: unless developing countries know how much money to expect, when and for what, they cannot effectively plan their efforts to address and respond to climate change. But a new scorecard, based on the extent to which developed countries meet a set of common-sense criteria in their climate finance reports to the UN, reveals that we have a long way to go in making climate finance transparent. Even the highest-scoring countries — Norway and Japan — barely reach a 50 per cent score across the 25 criteria evaluated. We urgently need an international registry of funds that provides comprehensive, detailed, consistent and transparent accounting and reporting measures at the project level.

Making sense of traumatic memories: memory qualities and psychological symptoms in emerging adults with and without abuse histories.

Science.gov (United States)

Follmer Greenhoot, Andrea; Sun, Shengkai; Bunnell, Sarah L; Lindboe, Katherine

2013-01-01

This study explored the connections between multiple measures of meaning making and psychological adjustment in people with and without histories of abuse. Young adults (n =177), recollected their three most stressful memories and rated them on importance and emotional and sensory qualities. We analysed the narratives for lexical markers of meaning making and explicit references to meaning or meaning-making attempts. There was little overlap between self-reported qualities and narrative content, and they were differentially predictive of psychological symptoms and transient emotional reactions. Consistent with the PTSD literature, more salient self-report memory characteristics (e.g., visceral emotions), and negative emotion and sensation terms predicted more symptoms. The narrative indices provided the best prediction to psychological adjustment, with several meaning indices (e.g., references to positive impact) predicting reduced symptoms, particularly for the Abuse group. Contrary to meaning-making models, resolutions predicted more symptoms, suggesting that aversive feelings during memory telling may trigger on-the-spot sense making to cope with distress.

Computational Studies of pH Sensing Design Principles in Proteins

Science.gov (United States)

Garrido Ruiz, Diego

Changes in pH are important regulatory signals for biological function, under physiological and pathological conditions. Recent advances in computer simulations strategies have made the exploration of the effects of charge titrations on protein function possible. In this work, I make use of these strategies to investigate the thermodynamic coupling between conformation and protonation states that give rise to pH-dependent function. As motivation for the rest of the work, I start by presenting a collaborative investigation on a pH-sensing mutant of the EGFR tyrosine kinase common to a set of distinct cancers. From then, I reduce the complexity of the systems under study to build models where exact enumeration of states is possible to inquire about the nature of the couplings between protonation states and conformation. Finally, I discuss detailed simulations of pH-sensing proteins for which I use the expectations and insights generated with simple models to identify and interpret couplings of interest for pH-dependent behavior.

Chen, Connie; Haddad, David; Selsky, Joshua; Hoffman, Julia E; Kravitz, Richard L; Estrin, Deborah E; Sim, Ida

2012-08-09

Mobile phones and devices, with their constant presence, data connectivity, and multiple intrinsic sensors, can support around-the-clock chronic disease prevention and management that is integrated with daily life. These mobile health (mHealth) devices can produce tremendous amounts of location-rich, real-time, high-frequency data. Unfortunately, these data are often full of bias, noise, variability, and gaps. Robust tools and techniques have not yet been developed to make mHealth data more meaningful to patients and clinicians. To be most useful, health data should be sharable across multiple mHealth applications and connected to electronic health records. The lack of data sharing and dearth of tools and techniques for making sense of health data are critical bottlenecks limiting the impact of mHealth to improve health outcomes. We describe Open mHealth, a nonprofit organization that is building an open software architecture to address these data sharing and "sense-making" bottlenecks. Our architecture consists of open source software modules with well-defined interfaces using a minimal set of common metadata. An initial set of modules, called InfoVis, has been developed for data analysis and visualization. A second set of modules, our Personal Evidence Architecture, will support scientific inferences from mHealth data. These Personal Evidence Architecture modules will include standardized, validated clinical measures to support novel evaluation methods, such as n-of-1 studies. All of Open mHealth's modules are designed to be reusable across multiple applications, disease conditions, and user populations to maximize impact and flexibility. We are also building an open community of developers and health innovators, modeled after the open approach taken in the initial growth of the Internet, to foster meaningful cross-disciplinary collaboration around new tools and techniques. An open mHealth community and architecture will catalyze increased mHealth efficiency

Mobile Autonomous Sensing Unit (MASU: A Framework That Supports Distributed Pervasive Data Sensing

Directory of Open Access Journals (Sweden)

Esunly Medina

2016-07-01

Full Text Available Pervasive data sensing is a major issue that transverses various research areas and application domains. It allows identifying people’s behaviour and patterns without overwhelming the monitored persons. Although there are many pervasive data sensing applications, they are typically focused on addressing specific problems in a single application domain, making them difficult to generalize or reuse. On the other hand, the platforms for supporting pervasive data sensing impose restrictions to the devices and operational environments that make them unsuitable for monitoring loosely-coupled or fully distributed work. In order to help address this challenge this paper present a framework that supports distributed pervasive data sensing in a generic way. Developers can use this framework to facilitate the implementations of their applications, thus reducing complexity and effort in such an activity. The framework was evaluated using simulations and also through an empirical test, and the obtained results indicate that it is useful to support such a sensing activity in loosely-coupled or fully distributed work scenarios.

LEP dismantling starts

CERN Multimedia

2000-01-01

Since the end of November, various teams have been getting stuck into dismantling the LEP accelerator and its four experiments. After making the installations safe, the dismantling and removal of 40,000 tonnes of equipment is underway. Down in the tunnel, it is a solemn moment. It is 10 o'clock on 13 December and Daniel Regin, one of those heading the dismantling work, moves in on a magnet, armed with a hydraulic machine. Surrounded by teams gathered there for a course in dismantling, he makes the first cut into LEP. The great deconstruction has begun. In little over than a year, the accelerator will have been cleared away to make room for its successor, the LHC. The start of the operation goes back to 27 November. Because before setting about the machine with hydraulic shears and monkey wrenches, LEP had first to be made safe - it was important to make sure the machine could be taken apart without risk. All the SPS beam injection systems to LEP were cut off. The fluids used for cooling the magnets and superc...

Online catalog access and distribution of remotely sensed information

Science.gov (United States)

Lutton, Stephen M.

1997-09-01

Remote sensing is providing voluminous data and value added information products. Electronic sensors, communication electronics, computer software, hardware, and network communications technology have matured to the point where a distributed infrastructure for remotely sensed information is a reality. The amount of remotely sensed data and information is making distributed infrastructure almost a necessity. This infrastructure provides data collection, archiving, cataloging, browsing, processing, and viewing for applications from scientific research to economic, legal, and national security decision making. The remote sensing field is entering a new exciting stage of commercial growth and expansion into the mainstream of government and business decision making. This paper overviews this new distributed infrastructure and then focuses on describing a software system for on-line catalog access and distribution of remotely sensed information.

The physics of tokamak start-up

International Nuclear Information System (INIS)

Mueller, D.

2013-01-01

Tokamak start-up on present-day devices usually relies on inductively induced voltage from a central solenoid. In some cases, inductive startup is assisted with auxiliary power from electron cyclotron radio frequency heating. International Thermonuclear Experimental Reactor, the National Spherical Torus Experiment Upgrade and JT60, now under construction, will make use of the understanding gained from present-day devices to ensure successful start-up. Design of a spherical tokamak (ST) with DT capability for nuclear component testing would require an alternative to a central solenoid because the small central column in an ST has insufficient space to provide shielding for the insulators in the solenoid. Alternative start-up techniques such as induction using outer poloidal field coils, electron Bernstein wave start-up, coaxial helicity injection, and point source helicity injection have been used with success, but require demonstration of scaling to higher plasma current

Hyperspectral sensing of forests

Canada contains 10% of the world's forests covering an area of 418 million hectares. The sustainable management of these forest resources has become increasingly complex. Hyperspectral remote sensing can provide a wealth of new and improved information products to resource managers to make more informed decisions. Research in this area has demonstrated that hyperspectral remote sensing can be used to create more accurate products for forest inventory, forest health, foliar biochemistry, biomass, and aboveground carbon than are currently available. This paper surveys recent methods and results in hyperspectral sensing of forests and describes space initiatives for hyperspectral sensing.

Does peritoneal dialysis have a role in urgent-start end-stage kidney disease?

Science.gov (United States)

McQuillan, Rory F; Lok, Charmaine E

2018-04-19

Despite its many positive attributes, peritoneal dialysis remains underutilized, particularly in the United States. Urgent-start peritoneal dialysis (PD) has been proposed as a method of increasing PD prevalence. Urgent-start PD has been shown to be safe, feasible, and effective. However, urgent-start PD is also accompanied by several multidimensional challenges. This article is intended to equip the reader with a practical sense of whether an urgent-start PD program would be appropriate in his or her own clinical context and if appropriate, what factors would be necessary for such a program to flourish. As such, we summarize latent factors, which are necessary to consider before instituting an urgent-start PD. Then, using a series of clinical vignettes, highlight the component parts of a successful urgent-start PD program and the patient population who stand to benefit most from this strategy. The discussion is then balanced by presenting limitations to consider in the urgent-start PD approach. © 2018 Wiley Periodicals, Inc.

Use of Remote Sensing for Decision Support in Africa

Science.gov (United States)

Policelli, Frederick S.

2007-01-01

Over the past 30 years, the scientific community has learned a great deal about the Earth as an integrated system. Much of this research has been enabled by the development of remote sensing technologies and their operation from space. Decision makers in many nations have begun to make use of remote sensing data for resource management, policy making, and sustainable development planning. This paper makes an attempt to provide a survey of the current state of the requirements and use of remote sensing for sustainable development in Africa. This activity has shown that there are not many climate data ready decision support tools already functioning in Africa. There are, however, endusers with known requirements who could benefit from remote sensing data.

This paper explores the relationship between cognitive abilities and team performance in a start-up setting. We argue that performance in this setting hinges on three tasks: opportunity recognition, problem solving, and implementation. We theorize that cognitive ability at the individual level has...... others can be assigned to tasks that impose a greater cognitive load (problem solving or opportunity recognition). We present the results of a field experiment in which 573 students in 49 teams started up and managed real companies. We ensured exogenous variation in—otherwise random—team composition...... by assigning students to teams based on their measured cognitive abilities. Each team performed a variety of tasks, often involving complex decision making.

This lecture was just a taste of radar remote sensing techniques and applications. Other important areas include Stereo radar grammetry. PolInSAR for volumetric structure mapping. Agricultural monitoring, soil moisture, ice-mapping, etc. The broad range of sensor types, frequencies of observation and availability of sensors have enabled radar sensors to make significant contributions in a wide area of earth and planetary remote sensing sciences. The range of applications, both qualitative and quantitative, continue to expand with each new generation of sensors.

An eigenexpansion technique for modelling plasma start-up

International Nuclear Information System (INIS)

Pillsbury, R.D.

1989-01-01

An algorithm has been developed and implemented in a computer program that allows the estimation of PF coil voltages required to start-up an axisymmetric plasma in a tokamak in the presence of eddy currents in toroidally continuous conducting structures. The algorithm makes use of an eigen-expansion technique to solve the lumped parameter circuit loop voltage equations associated with the PF coils and passive (conducting) structures. An example of start-up for CIT (Compact Ignition Tokamak) is included

Start-Up Size Strategy and Risk Management: Impact on New Venture Performance

OpenAIRE

André van Stel; Andrew Burke; José Maria Millán; Concepcion Roman

2013-01-01

Start-up size is a key strategic decision for entrepreneurs. Should entrepreneurs start up close to minimum efficient scale or should they take less risks and start-up on a smaller scale? Previously, this strategic decision appeared to be one of simply making a choice between a higher risk/reward larger start-up versus a lower risk/reward smaller scale start-up. However, recent research on the relationship between risk management and performance (Burke, 2009) indicates that in situations of g...

Making big sense from big data in toxicology by read-across.

Science.gov (United States)

Hartung, Thomas

2016-01-01

Modern information technologies have made big data available in safety sciences, i.e., extremely large data sets that may be analyzed only computationally to reveal patterns, trends and associations. This happens by (1) compilation of large sets of existing data, e.g., as a result of the European REACH regulation, (2) the use of omics technologies and (3) systematic robotized testing in a high-throughput manner. All three approaches and some other high-content technologies leave us with big data--the challenge is now to make big sense of these data. Read-across, i.e., the local similarity-based intrapolation of properties, is gaining momentum with increasing data availability and consensus on how to process and report it. It is predominantly applied to in vivo test data as a gap-filling approach, but can similarly complement other incomplete datasets. Big data are first of all repositories for finding similar substances and ensure that the available data is fully exploited. High-content and high-throughput approaches similarly require focusing on clusters, in this case formed by underlying mechanisms such as pathways of toxicity. The closely connected properties, i.e., structural and biological similarity, create the confidence needed for predictions of toxic properties. Here, a new web-based tool under development called REACH-across, which aims to support and automate structure-based read-across, is presented among others.

Multi-Objective Optimization of Start-up Strategy for Pumped Storage Units

Jinjiao Hou

2018-05-01

Full Text Available This paper proposes a multi-objective optimization method for the start-up strategy of pumped storage units (PSU for the first time. In the multi-objective optimization method, the speed rise time and the overshoot during the process of the start-up are taken as the objectives. A precise simulation platform is built for simulating the transient process of start-up, and for calculating the objectives based on the process. The Multi-objective Particle Swarm Optimization algorithm (MOPSO is adopted to optimize the widely applied start-up strategies based on one-stage direct guide vane control (DGVC, and two-stage DGVC. Based on the Pareto Front obtained, a multi-objective decision-making method based on the relative objective proximity is used to sort the solutions in the Pareto Front. Start-up strategy optimization for a PSU of a pumped storage power station in Jiangxi Province in China is conducted in experiments. The results show that: (1 compared with the single objective optimization, the proposed multi-objective optimization of start-up strategy not only greatly shortens the speed rise time and the speed overshoot, but also makes the speed curve quickly stabilize; (2 multi-objective optimization of strategy based on two-stage DGVC achieves better solution for a quick and smooth start-up of PSU than that of the strategy based on one-stage DGVC.

Healthy People 2020 established a national objective to increase the proportion of 9th-to-12th-grade students reporting sufficient sleep. A salient approach for achieving this objective is to delay middle and high school start times. Despite decades of research supporting the benefits of delayed school start times on adolescent sleep, health, and well-being, progress has been slow. Accelerating progress will require new approaches incorporating strategies that influence how school policy decisions are made. In this commentary, we introduce four strategies that influence decision-making processes and demonstrate how they can be applied to efforts aimed at changing school start time policies.

2015-01-01

High agreement is a common objective when annotating data for word senses. However, a number of factors make perfect agreement impossible, e.g. the limitations of the sense inventories, the difficulty of the examples or the interpretation preferences of the annotations. Estimating potential...... agreement is thus a relevant task to supplement the evaluation of sense annotations. In this article we propose two methods to predict agreement on word-annotation instances. We experiment with a continuous representation and a three-way discretization of observed agreement.

Full Text Available No abstract available. Article truncated at 150 words. Starting a new practice may seem like a daunting task. The purpose of this article is to demystify the process of creating a new practice from the beginning. The cardinal rule is to keep costs low and not to outsource work that can easily be performed by any competent physician and staff. You do not need a manager, lawyer, business partner, coder or biller individually; you may be able to perform many of these services yourself. What you do need is a commitment to making your practice a success. Do not spend too much on your office space, furnishings or equipment. Start with the bare essentials. Immediately start applying to all insurance companies especially Medicare. Request an employer identification number. Set up a basic business banking account and submit the account number to the insurance companies you plan to work with. You can purchase an entire electronic healthcare record (EHR …

'The Problem with Men': Working-class Men Making Sense of Men's Health on Television.

Science.gov (United States)

Hodgetts, Darrin; Chamberlain, Kerry

2002-05-01

Men have higher rates of premature death than women, and may arguably have higher rates of serious illness. One explanation often suggested to account for this is that men are considered to be stoical about illness and reluctant to seek help for it. This article explores the role of media representations in the construction of men's views about health. We investigate how a small group of lower socio-economic status men make sense of the reluctance to seek help notion through an analysis of texts from three sources: a television health documentary, individual interviews with the men and a focus group discussion in which the men discuss the documentary. The television documentary frames its presentation to promote early detection and help-seeking. We conclude that televised coverage of men's health is an important site of social discourse through which men's health is rendered meaningful. However, it is not accepted passively, but negotiated, resisted and interpreted into men's lives.

Full Text Available The paper considers the issue of children preparation for school in so called starting schools. In author’s opinion, the arts disciplines such as music, drawing and choreography can develop the aesthetic sense, moral qualities, more optimistic world outlook and respectful  attitude; the child develops creative skills and beauty perception both in fine arts and wild life.The author looks at the problems of planning and organizing the music training of preschool children, the different requirements for and concepts of the preschool and primary school normative documents being analyzed. The paper substantiates the effectiveness of poly-artistic and activity approaches to the split-level teaching, in particular – the method of projecting the familiar actions onto some sort of artistic activities. Based on the succession of preschool and primary school training, the author specifies the goals of music classes in starting schools, and outlines the most relevant game activities of role plays, didactic plays and contests.The paper is addressed to preschool and primary school teachers, music teachers, as well as methodologists and researchers dealing with preschool teaching.

Remote sensing is defined as data acquisition of an object, deprived physical contact. Fundamentally, most remote sensing applications are referred to as the use of satellite- or aircraft-based sensor technologies to detect and classify objects mainly on Earth or other planets. In the last years there have been efforts to bring the important subject of remote sensing into schools, however, most of these attempts focused on geography disciplines - restricting to the applications of remote sensing and to a less extent the technique itself and the physics behind it. Optical remote sensing is based on physical principles and technical devices, which are very meaningful from a theoretical point of view as well as for "hands-on" teaching. Some main subjects are radiation, atom and molecular physics, spectroscopy, as well as optics and the semiconductor technology used in modern digital cameras. Thus two objectives were outlined for this project: 1) to investigate the possibilities of using remote sensing techniques in physics teaching, and 2) to identify its impact on pupil's interest in the field of natural sciences. This joint project of the DLR_School_Lab, Oberpfaffenhofen of the German Aerospace Center (DLR) and the Earth and Planetary Image Facility (EPIF) at BGU, was conducted in 2016. Thirty teenagers (ages 16-18) participated in the project and were exposed to the cutting edge methods of earth observation. The pupils on both sides participated in the project voluntarily, knowing that at least some of the project's work had to be done in their leisure time. The pupil's project started with a day at EPIF and DLR respectively, where the project task was explained to the participants and an introduction to remote sensing of vegetation was given. This was realized in lectures and in experimental workshops. During the following two months both groups took several measurements with modern optical remote sensing systems in their home region with a special focus on flora

Entrepreneurial Intention: South African Youth’s Willingness to Start Tourism Businesses

Full Text Available Previous studies have recognised entrepreneurship as a tool capable of driving a nation’s economy. This study explored tourism entrepreneurial intention of South African youth, and analysed relationships between entrepreneurship statements on the one hand, and entrepreneurial intention and entrepreneurial impact on the other hand. A questionnaire survey was used to collect data from simple-randomly selected 220 youth living in Mtubatuba Local Municipality, KwaZulu-Natal Province of South Africa. Descriptive, bivariate and multivariate data analyses yield information to address research objectives. Significant proportion of the youth have entrepreneurial intention, these youth want to solve problems, are willing to pursuing their dreams, have internal locus of control, have positive outlook, have the ability to identify opportunities, and above all have strong sense of empathy. South African Department of Labour needs to develop an operational plan to provide business education, entrepreneurial skills, and relevant support that can empower the youth to start their own businesses. This study validates the alignment of entrepreneurship roles to those of making a difference, innovation, leadership, and self-belief; and shares a positive outlook for the South African economy if the enabling political and economic conditions are created.

Husserl’s theory of noematic sense

Directory of Open Access Journals (Sweden)

Nikolić Olga

2016-01-01

Full Text Available After Husserl’s transcendental turn and the discovery of the correlation between consciousness and the world the concept of the noema becomes one of the constant leitmotifs of Husserl’s philosophy. My paper will be devoted to the clarification of this concept and its implications for Husserl’s theory of sense. The leading question will be: How can the noema play the role of both the sense and the objective correlate of the intentional act? I will start with presenting the problematic of sense in Husserl’s phenomenology from the Logical Investigations to the Ideas I. The central part of my paper will be devoted to the influential debate regarding the interpretation of the noema. Finally, I intend to point out the most important ways in which the notion of the noema becomes enriched in later Husserl’s philosophy, as well as the difference between linguisitic and non-linguistic sense, based on the Analyses Concerning Passive and Active Synthesis. I hope to show that Husserl’s phenomenological theory of sense offers a valuable alternative to the exclusively language-oriented theories of sense. [This paper is the abridged and reworked version of my Master’s Thesis "Husser’s Notion of the Noema: The Phenomenological Theory of Sense" defended at KU Leuven in January 2016.

Commentary: so the pendulum swings--making sense of the duty to protect.

Science.gov (United States)

Fox, Patrick K

2010-01-01

Psychiatry has been struggling for nearly 40 years to make sense of the duty to protect. The great jurisdictional disparity as to what constitutes the duty has been a significant contributing factor. The American Psychiatric Association (APA) released the Model Statute in 1987 to establish a framework to guide legislators and courts toward consensus, to some effect. In response to case law and statutory requirements in most states, psychiatric practice has incorporated the assessment of risk to third parties by patients as an essential element of psychiatric assessment and care. Although court cases shortly after the Tarasoff decision expanded the scope and breadth of the duty to protect, in recent years there appears to have been a shift toward a more narrow interpretation as to what conditions must exist to find a defendant psychiatrist guilty of failing to exercise the duty properly. The threshold for the duty to warn or protect often rests precariously beside the criteria permitting an exception to confidentiality, placing the psychiatrist in a tenuous position. If appellate verdicts continue to find for the defendant psychiatrist in cases claiming a breach of the duty to protect, it could have an impact on how psychiatrists assess and manage threats made by patients toward third parties.

Conversational sensing

Preece, Alun; Gwilliams, Chris; Parizas, Christos; Pizzocaro, Diego; Bakdash, Jonathan Z.; Braines, Dave

2014-05-01

Recent developments in sensing technologies, mobile devices and context-aware user interfaces have made it pos- sible to represent information fusion and situational awareness for Intelligence, Surveillance and Reconnaissance (ISR) activities as a conversational process among actors at or near the tactical edges of a network. Motivated by use cases in the domain of Company Intelligence Support Team (CoIST) tasks, this paper presents an approach to information collection, fusion and sense-making based on the use of natural language (NL) and controlled nat- ural language (CNL) to support richer forms of human-machine interaction. The approach uses a conversational protocol to facilitate a ow of collaborative messages from NL to CNL and back again in support of interactions such as: turning eyewitness reports from human observers into actionable information (from both soldier and civilian sources); fusing information from humans and physical sensors (with associated quality metadata); and assisting human analysts to make the best use of available sensing assets in an area of interest (governed by man- agement and security policies). CNL is used as a common formal knowledge representation for both machine and human agents to support reasoning, semantic information fusion and generation of rationale for inferences, in ways that remain transparent to human users. Examples are provided of various alternative styles for user feedback, including NL, CNL and graphical feedback. A pilot experiment with human subjects shows that a prototype conversational agent is able to gather usable CNL information from untrained human subjects.

Primates' Socio-Cognitive Abilities: What Kind of Comparisons Makes Sense?

Science.gov (United States)

Byrnit, Jill T

2015-09-01

Referential gestures are of pivotal importance to the human species. We effortlessly make use of each others' referential gestures to attend to the same things, and our ability to use these gestures show themselves from very early in life. Almost 20 years ago, James Anderson and colleagues presented an experimental paradigm with which to examine the use of referential gestures in non-human primates: the object-choice task. Since then, numerous object-choice studies have been made, not only with primates but also with a range of other animal taxa. Surprisingly, several non-primate species appear to perform better in the object-choice task than primates do. Different hypotheses have been offered to explain the results. Some of these have employed generalizations about primates or subsets of primate taxa that do not take into account the unparalleled diversity that exists between species within the primate order on parameters relevant to the requirements of the object-choice task, such as social structure, feeding ecology, and general morphology. To examine whether these broad primate generalizations offer a fruitful organizing framework within which to interpret the results, a review was made of all published primate results on the use of gazing and glancing cues with species ordered along the primate phylogenetic tree. It was concluded that differences between species may be larger than differences between ancestry taxa, and it is suggested that we need to start rethinking why we are testing animals on experimental paradigms that do not take into account what are the challenges of their natural habitat.

Making sense of quantum mechanics

Bricmont, Jean

2016-01-01

This book explains, in simple terms, with a minimum of mathematics, why things can appear to be in two places at the same time, why  correlations between simultaneous events occurring far apart cannot be explained by local mechanisms, and why, nevertheless, the quantum theory can be understood in terms of matter in motion. No need to worry, as some people do, whether a cat can be both dead and alive, whether the moon is there when nobody looks at it, or whether quantum systems need an observer to acquire definite properties. The author’s inimitable and even humorous style makes the book a pleasure to read while bringing a new clarity to many of the longstanding puzzles of quantum physics.

Pervasive sensing

The coordinated exploitation of modern communication, micro- sensor and computer technologies makes it possible to give global reach to our senses. Web-cameras for vision, web- microphones for hearing and web-'noses' for smelling, plus the abilities to sense many factors we cannot ordinarily perceive, are either available or will be soon. Applications include (1) determination of weather and environmental conditions on dense grids or over large areas, (2) monitoring of energy usage in buildings, (3) sensing the condition of hardware in electrical power distribution and information systems, (4) improving process control and other manufacturing, (5) development of intelligent terrestrial, marine, aeronautical and space transportation systems, (6) managing the continuum of routine security monitoring, diverse crises and military actions, and (7) medicine, notably the monitoring of the physiology and living conditions of individuals. Some of the emerging capabilities, such as the ability to measure remotely the conditions inside of people in real time, raise interesting social concerns centered on privacy issues. Methods for sensor data fusion and designs for human-computer interfaces are both crucial for the full realization of the potential of pervasive sensing. Computer-generated virtual reality, augmented with real-time sensor data, should be an effective means for presenting information from distributed sensors.

Making sense of climate risk information: The case of future indoor climate risks in Swedish churches

Directory of Open Access Journals (Sweden)

Gustaf Leijonhufvud

2016-01-01

Full Text Available Organizations and institutions managing built heritage have to make use of increasingly detailed, elaborate and complex climate change impact assessments. It is a challenge to determine how, when and by whom climate predictions should be translated into risk estimates usable for decision-making. In this paper results from the Climate for Culture project are used to study how heritage decision-makers interpret future indoor climate-related risks to Swedish churches. Different sets of risk maps were presented to ten engineers, ten building conservators and five experts on indoor climate related risks. Interviews were used to understand how the interviewees made sense of the presented information and if they associated it with a perceived need for adaptation. The results show that the risks were interpreted and assessed largely dependent on their pre-understanding and familiarity with the individual risks. The magnitude of change and the lack of uncertainty estimates were subordinate to the overall impression of the information as being credible and salient. The major conclusion is that the dissemination of risk information, also from projects which at the outset have aimed at producing knowledge relevant for end-users, should be both customized and tested in collaborative efforts by stakeholders and scientists.

Exploring the Interconnected Trauma of Personal, Social, and Structural Stressors: Making "Sense" of Senseless Violence.

Science.gov (United States)

Abo-Zena, Mona M

2017-01-02

Although violence is a timeless characteristic of human behavior and history, its prevalence and many forms are proliferated repeatedly through the media. In particular, "senseless" violence against both random and targeted victims puzzles and petrifies onlookers and survivors. Integrating developmental psychology with critical theory, this manuscript begins with a conceptual definition of senseless violence that is coupled with a mapping of the personal, social, and structural etiologies of such violence. This inquiry explores the origins, contexts, and varied manifestations of violence, helps redirect sense-making around such violence, and informs how to cope with and possibly reduce or mitigate it. Utilizing a person-centered perspective from multiple points of view, the analysis focuses primarily on the everyday or chronic experiences of stressors and their relation to internalized and externalized types of violence (i.e., mass shootings, interpersonal violence, self-injury). The manuscript concludes with ways to reduce violence and promote justice on personal, social, and structural levels.

Making Sense of Participant Experiences: Interpretative Phenomenological Analysis in Midwifery Research

Directory of Open Access Journals (Sweden)

Samantha J Charlick

2016-06-01

Full Text Available Selecting the most appropriate methodology for research as a doctoral student is one of the most important yet difficult decisions. Not only should the methodology suit the research question, it is important that it resonates with the philosophy of one’s discipline and produces needed results that will contribute to knowledge. Interpretative phenomenological analysis (IPA is an approach to qualitative enquiry. IPA seeks to explore how individuals make sense of their major life experiences and is committed to the detailed study of each particular case before moving to broader claims. In the field of midwifery, midwives work with women throughout pregnancy, childbirth and the early postnatal period, offering individualized care based on the unique needs of each woman. IPA aligns with this women-centered philosophy as it offers a methodological approach that considers the individual in a local context. By capturing context specific situations, IPA allows broad-based knowledge to be contextualized within a social and cultural context, producing relevant findings. Thus the access to IPA studies will enable midwives to better care for women and their families through understanding the experiences and perceptions of those in their scope of practice. This paper presents the theoretical framework leading to practical guidelines on how to con-duct a doctoral-level IPA study, as experienced by the first author. It also addresses the advantages and challenges around utilizing IPA, illustrated through examples from the doc-toral student’s study on the journey of exclusive breastfeeding in Australia.

2016-01-01

The spinal cord integrates and relays somatosensory input, leading to complex motor responses. Research over the past couple of decades has identified transcription factor networks that function during development to define and instruct the generation of diverse neuronal populations within the spinal cord. A number of studies have now started to connect these developmentally defined populations with their roles in somatosensory circuits. Here, we review our current understanding of how neuronal diversity in the dorsal spinal cord is generated and we discuss the logic underlying how these neurons form the basis of somatosensory circuits.

Sensing Athletes: Sensory Dimensions of Recreational Endurance Sports

Directory of Open Access Journals (Sweden)

Stefan Groth

2017-12-01

Full Text Available Sport has become increasingly popular with recreational athletes over the last couple of decades. This has only gained minimal attention so far from scholars interested in the relations between recreational sports and everyday culture. With this paper, we seek to contribute to this field by scrutinising the sensory dimensions of recreational sport. Rather than probing into or highlighting isolated senses, we look at sensory dimensions understood as a combination of different, non-separable sensory experiences featured in recreational endurance sports. We are interested in how senses play a role for recreational endurance athletes in running, triathlon and cycling both in training and competition. We start by examining how cultural and social dimensions are inextricably linked to doing sports. Secondly, we show how different configurations of the senses and their communicative mediation are contingent on sport disciplines, specific settings, technology, development and change as sensory careers over time. Thirdly, we discuss the kinaesthetic dimensions of doing sports in relation to the senses and the role of atmospheres. We conclude by arguing that highlighting specific senses by athletes is a cultural practice that calls for a holistic analysis of senses in sport, and outline some methodological implications for research on the senses.

Modulation of gastrointestinal nutrient sensing pathways provides a promising a new approach for the treatment of metabolic diseases including diabetes and obesity. The calcium-sensing receptor has been identified as a key receptor involved in mineral and amino acid nutrient sensing and thus is an attractive target for modulation in the intestine. Herein we describe the optimization of gastrointestinally restricted calcium-sensing receptor agonists starting from a 3-aminopyrrolidine-containing template leading to the identification of GI-restricted agonist 19 (GSK3004774).

The Importance of Sensing Own's Movements in the World for the Sense of Personal Identity

Directory of Open Access Journals (Sweden)

Mariana Broens

2012-01-01

Full Text Available Within philosophy and cognitive science, the focus in relation to the problem of personal identity has been almost exclusively on the brain. We submit that the resulting neglect of the body and of bodily movements in the world has been detrimental in understanding how organisms develop a sense of identity. We examine the importance of sensing one’s own movements for the development of a basic, nonconceptual sense of self. More specifically, we argue that the origin of the sense of self stems from the sensitivity to spontaneous movements. Based on this, the organism develops a sense of “I move” and, finally, a sense of “I can move”. Proprioception and kinesthesis are essential in this development. At the same time, we argue against the traditional dichotomy between so-called external and internal senses, agreeing with Gibson that perception of the self and of the environment invariably go together. We discuss a traditional distinction between two aspects of bodily self: the body sense and the body image. We suggest that they capture different aspects of the sense of self. We argue that especially the body sense is of great importance to our nonconceptual sense of self. Finally, we attempt to draw some consequences for research in cognitive science, specifically in the area of robotics, by examining a case of missing proprioception. We make a plea for robots to be equipped not just with external perceptual and motor abilities but also with a sense of proprioception. This, we submit, would constitute one further step towards understanding creatures acting in the world with a sense of themselves.

The recognition, assessment and management of pain in hospital settings is suboptimal, and is a particular challenge in patients with dementia. The existing process guiding pain assessment and management in clinical settings is based on the assumption that nurses follow a sequential linear approach to decision making. In this paper we re-evaluate this theoretical assumption drawing on findings from a study of pain recognition, assessment and management in patients with dementia. To provide a revised conceptual model of pain recognition, assessment and management based on sense-making theories of decision making. The research we refer to is an exploratory ethnographic study using nested case sites. Patients with dementia (n=31) were the unit of data collection, nested in 11 wards (vascular, continuing care, stroke rehabilitation, orthopaedic, acute medicine, care of the elderly, elective and emergency surgery), located in four NHS hospital organizations in the UK. Data consisted of observations of patients at bedside (170h in total); observations of the context of care; audits of patient hospital records; documentary analysis of artefacts; semi-structured interviews (n=56) and informal open conversations with staff and carers (family members). Existing conceptualizations of pain recognition, assessment and management do not fully explain how the decision process occurs in clinical practice. Our research indicates that pain recognition, assessment and management is not an individual cognitive activity; rather it is carried out by groups of individuals over time and within a specific organizational culture or climate, which influences both health care professional and patient behaviour. We propose a revised theoretical model of decision making related to pain assessment and management for patients with dementia based on theories of sense-making, which is reflective of the reality of clinical decision making in acute hospital wards. The revised model recognizes the

Logical Normativity and Common Sense Reasoning

Directory of Open Access Journals (Sweden)

Evandro Agazzi

2011-04-01

Full Text Available Logic, considered as a technical discipline inaugurated by Aristotle and typically represented by the variety of the modern logical calculi, constitutes a clarification and refinement of a conviction and practice present in common sense, that is, the fact that humans believe that truth can be acquired not only by immediate evidence, but also by means of arguments. As a first step logic can be seen as a “descriptive” record of the main forms of the arguments present in common sense, but the fact that some of these patterns can actually allow for the derivation of false consequences from true premises imposes the task of making explicit what patterns correspond to a “correct reasoning” and what not. At this point logic (that contains the presentation of such patterns appears endowed with a “normative” characteristic. This amounts to saying that logical calculi are intended to adequately mirror the intuitive notion of “logical consequence” and in this sense they cannot be totally arbitrary or conventional, but must satisfy certain basic requirements such as the conditions of soundness and (as far as possible of semantic completeness. In such a way they are “judged” according to the fundamental requirements present at the level of common sense and appear as “idealizations” of the kinds of reasoning practiced in common sense. For this reason also several kinds of logical calculi are fully justified since they make explicit in an idealized form the concrete ways of reasoning that are imposed by the particular domain of reference of the discipline in which they are used and which are basically recognized in common sense.

Virtual-reality solutions have successfully been used to train distributed teams. This study aimed to investigate the correlation between user characteristics and sense of presence in an online virtual-reality environment where distributed teams are trained. A greater sense of presence has the potential to make training in the virtual environment more effective, leading to the formation of teams that perform better in a real environment. Being able to identify, before starting online training, those user characteristics that are predictors of a greater sense of presence can lead to the selection of trainees who would benefit most from the online simulated training. This is an observational study with a retrospective postsurvey of participants' user characteristics and degree of sense of presence. Twenty-nine members from 3 Air Force National Guard Medical Service expeditionary medical support teams participated in an online virtual environment training exercise and completed the Independent Television Commission-Sense of Presence Inventory survey, which measures sense of presence and user characteristics. Nonparametric statistics were applied to determine the statistical significance of user characteristics to sense of presence. Comparing user characteristics to the 4 scales of the Independent Television Commission-Sense of Presence Inventory using Kendall τ test gave the following results: the user characteristics "how often you play video games" (τ(26)=-0.458, Pvirtual environment experience such as dizziness, nausea, headache, and eyestrain. The user characteristic "knowledge of virtual reality" was significantly related to engagement (τ(26)=0.463, Pvirtual environments and experience with gaming environments report a higher sense of presence that indicates that they will likely benefit more from online virtual training. Future research studies could include a larger population of expeditionary medical support, and the results obtained could be used to create

The US National Research Council (NRC) recommended that: "The U.S. government, working in concert with the private sector, academe, the public, and its international partners, should renew its investment in Earth-observing systems and restore its leadership in Earth science and applications." in response to the NASA Earth Science Division's request to prioritize research areas, observations, and notional missions to make those objectives. In this presentation, we will discuss our approach to connect remote sensing science to decision support applications by establishing a framework to integrate direct measurements, earth system models, inventories, and other information to accurately estimate fresh water resources in global, regional, and local scales. We will discuss our demonstration projects and lessons learned from the experience. Deploying a monitoring system that offers sustained, accurate, transparent and relevant information represents a challenge and opportunity to a broad community spanning earth science, water resource accounting and public policy. An introduction to some of the scientific and technical infrastructure issues associated with monitoring systems is offered here to encourage future treatment of these topics by other contributors as a concluding remark.

Fictional narratives have rarely been used in medical anthropological research. This article illustrates the value of such narratives by examining how young people in southeastern Nigeria navigate the cultural resources available to them to make sense of HIV in their creative writing. Using thematic data analysis and narrative-based methodologies, it analyzes a sample (N = 120) from 1,849 narratives submitted by Nigerian youth to the 2005 Scenarios from Africa scriptwriting contest on the theme of HIV. The narratives are characterized by five salient themes: tragedy arising from the incompatibility of sex outside marriage and kinship obligations; female vulnerability and blame; peer pressure and moral ambivalence; conservative Christian sexual morality; and the social and family consequences of HIV. We consider the strengths and limitations of this narrative approach from a theoretical perspective and by juxtaposing our findings with those generated by Daniel Jordan Smith using standard ethnographic research methods with a similar Igbo youth population.

Why Awareness of LGBT issues in the Physics Community Makes Sense

Hicks, Janice

2012-02-01

A thriving innovation ecology requires diversity of perspective and knowledge. We want to attract and retain the best possible talent to Science and Engineering, particularly after expensive investments in training of faculty, postdoctoral fellows and students. Participants who bring their authentic identity to work are much more efficient, as it takes a lot of energy to stay in the closet. It is a concern that so few S&E faculty are out of the closet -- we don't know the numbers and they are difficult to obtain. This makes it difficult for the younger generation of students to relate as they do not see sexual orientation as an obstacle. It is also important for LGBT people to be visible in order to benefit from workplace policies such as family leave and other benefits. There are some activities to promote a positive view of LGBT people in S&E. The National Organization of Gay and Lesbian Scientists and Technical Professionals (NOGLSTP) has been in existence since 1983, and holds receptions and symposia at the AAAS meeting and other professional society meetings, as well as a symposium called ``Out to Innovate,'' next to be held October 13-14, 2012 at Ohio State University. The American Chemical Society started an LGBT subdivision of its Division of Professional Relations in 2010. Much more needs to be done to educate leaders so they can speak knowledgably about LGBT issues. Their ability to do so can affect their success in hiring and retaining top talent.

Asia: fighting HIV / AIDS makes business sense.

Science.gov (United States)

1999-11-15

Three Asian companies are investing in HIV/AIDS education and prevention schemes because they are starting to feel the effects of the HIV/AIDS pandemic on their workforces. A total of 17 companies from the region signed a document in the Fifth International Congress on AIDS in Asia and the Pacific committing to the fight against AIDS. The group said that effective workplace programs can prevent an increase in absenteeism, health care costs and labor turnover, a decrease in productivity, loss of experienced personnel and the need for increased resources to hire and retrain replacements. American International Assurance in Thailand accredits companies with effective HIV/AIDS campaigns in the workplace and gives them a 5-10% discount on premiums on group life insurance policies. At Freeport Mining in Indonesia, an HIV/AIDS campaign markedly improved condom usage rates and decreased incidence of sexually transmitted diseases (STDs) among workers. Meanwhile, India's Tata Tea Limited expanded its health services to include surveys, training, education, and counseling on HIV/AIDS and STDs.

Hydrological Controls on Floodplain Forest Phenology Assessed using Remotely Sensed Vegetation Indices

Science.gov (United States)

Lemon, M. G.; Keim, R.

2017-12-01

Although specific controls are not well understood, the phenology of temperate forests is generally thought to be controlled by photoperiod and temperature, although recent research suggests that soil moisture may also be important. The phenological controls of forested wetlands have not been thoroughly studied, and may be more controlled by site hydrology than other forests. For this study, remotely sensed vegetation indices were used to investigate hydrological controls on start-of-season timing, growing season length, and end-of-season timing at five floodplains in Louisiana, Arkansas, and Texas. A simple spring green-up model was used to determine the null spring start of season time for each site as a function of land surface temperature and photoperiod, or two remotely sensed indices: MODIS phenology data product and the MODIS Nadir Bidirectional Reflectance Distribution Function-Adjusted Reflectance (NBAR) product. Preliminary results indicate that topographically lower areas within the floodplain with higher flood frequency experience later start-of-season timing. In addition, start-of-season is delayed in wet years relative to predicted timing based solely on temperature and photoperiod. The consequences for these controls unclear, but results suggest hydrological controls on floodplain ecosystem structure and carbon budgets are likely at least partially expressed by variations in growing season length.

[Factors influencing the sense of unintegration of thoughts in maintaining anger].

Endo, Hiroko; Yukawa, Shintaro

2013-12-01

Endo and Yukawa (2012) investigated the process of maintaining anger and demonstrated that a sense of unintegration of thoughts maintained anger by promoting recurrent thinking and avoidance behavior. Our present study examined how personality characteristics and situational factors affected the process of maintaining anger. Undergraduates (N=713) wrote about an anger episode, and completed questionnaires assessing their sense of unintegration of thoughts, recurrent thinking, avoidance behaviors, and maintaining anger. The questionnaires also assessed personality characteristics such as difficulty in identifying feelings, and situational factors such as the need for maintaining relationships, anger arousability, and meaning-making for the anger episode. The results of covariance structure analysis indicated that difficulties in identifying feelings and anger arousability contributed to maintaining anger by increasing the sense of unintegration of thoughts just after the episode. However, the need for maintaining relationships directly reduced the sense of unintegration of thoughts just after the episode, and indirectly decreased the present sense of unintegration of thoughts by meaning-making. Moreover, although recurrent thinking promoted the current sense of unintegration of thoughts, it also provided meaning.

Evidence shows that Smart Cities are starting to materialise in our lives through the gradual introduction of the Internet of Things (IoT) paradigm. In this scope, crowdsensing emerges as a powerful solution to address environmental monitoring, allowing to control air pollution levels in crowded urban areas in a distributed, collaborative, inexpensive and accurate manner. However, even though technology is already available, such environmental sensing devices have not yet reached consumers. In this paper, we present an analysis of candidate technologies for crowdsensing architectures, along with the requirements for empowering users with air monitoring capabilities. Specifically, we start by providing an overview of the most relevant IoT architectures and protocols. Then, we present the general design of an off-the-shelf mobile environmental sensor able to cope with air quality monitoring requirements; we explore different hardware options to develop the desired sensing unit using readily available devices, discussing the main technical issues associated with each option, thereby opening new opportunities in terms of environmental monitoring programs.

This operation was defined as 'seven days of platform live support' (main target of this paper). (author)

Making sense of diversity in the workplace: organizational justice and language abstraction in employees' accounts of diversity-related incidents.

Science.gov (United States)

Roberson, Quinetta M; Stevens, Cynthia Kay

2006-03-01

To discern patterns of employee sense-making about workplace diversity, the authors analyzed 751 natural language accounts of diversity incidents from 712 workers in one department of a large organization. Six generic incident types emerged: discrimination, representation, treatment by management, work relationships, respect between groups, and diversity climates. Consistent with hypotheses, incidents that respondents viewed as negative, accounts from women, and those involving members of respondents' in-groups were more likely to cite justice issues. Partially consistent with research on the linguistic intergroup bias, both negative and positive accounts involving out-group members and accounts from men were more likely to be expressed using abstract verb forms. The authors discuss future opportunities to integrate research on diversity, justice, and the linguistic category model.

Synthetic and Bio-Artificial Tactile Sensing: A Review

Directory of Open Access Journals (Sweden)

Maria Chiara Carrozza

2013-01-01

Full Text Available This paper reviews the state of the art of artificial tactile sensing, with a particular focus on bio-hybrid and fully-biological approaches. To this aim, the study of physiology of the human sense of touch and of the coding mechanisms of tactile information is a significant starting point, which is briefly explored in this review. Then, the progress towards the development of an artificial sense of touch are investigated. Artificial tactile sensing is analysed with respect to the possible approaches to fabricate the outer interface layer: synthetic skin versus bio-artificial skin. With particular respect to the synthetic skin approach, a brief overview is provided on various technologies and transduction principles that can be integrated beneath the skin layer. Then, the main focus moves to approaches characterized by the use of bio-artificial skin as an outer layer of the artificial sensory system. Within this design solution for the skin, bio-hybrid and fully-biological tactile sensing systems are thoroughly presented: while significant results have been reported for the development of tissue engineered skins, the development of mechanotransduction units and their integration is a recent trend that is still lagging behind, therefore requiring research efforts and investments. In the last part of the paper, application domains and perspectives of the reviewed tactile sensing technologies are discussed.

TrustRank: a Cold-Start tolerant recommender system

The explosive growth of the World Wide Web leads to the fast advancing development of e-commerce techniques. Recommender systems, which use personalised information filtering techniques to generate a set of items suitable to a given user, have received considerable attention. User- and item-based algorithms are two popular techniques for the design of recommender systems. These two algorithms are known to have Cold-Start problems, i.e., they are unable to effectively handle Cold-Start users who have an extremely limited number of purchase records. In this paper, we develop TrustRank, a novel recommender system which handles the Cold-Start problem by leveraging the user-trust networks which are commonly available for e-commerce applications. A user-trust network is formed by friendships or trust relationships that users specify among them. While it is straightforward to conjecture that a user-trust network is helpful for improving the accuracy of recommendations, a key challenge for using user-trust network to facilitate Cold-Start users is that these users also tend to have a very limited number of trust relationships. To address this challenge, we propose a pre-processing propagation of the Cold-Start users' trust network. In particular, by applying the personalised PageRank algorithm, we expand the friends of a given user to include others with similar purchase records to his/her original friends. To make this propagation algorithm scalable to a large amount of users, as required by real-world recommender systems, we devise an iterative computation algorithm of the original personalised TrustRank which can incrementally compute trust vectors for Cold-Start users. We conduct extensive experiments to demonstrate the consistently improvement provided by our proposed algorithm over the existing recommender algorithms on the accuracy of recommendations for Cold-Start users.

Electroactive polymers for sensing

Science.gov (United States)

2016-01-01

Electromechanical coupling in electroactive polymers (EAPs) has been widely applied for actuation and is also being increasingly investigated for sensing chemical and mechanical stimuli. EAPs are a unique class of materials, with low-moduli high-strain capabilities and the ability to conform to surfaces of different shapes. These features make them attractive for applications such as wearable sensors and interfacing with soft tissues. Here, we review the major types of EAPs and their sensing mechanisms. These are divided into two classes depending on the main type of charge carrier: ionic EAPs (such as conducting polymers and ionic polymer–metal composites) and electronic EAPs (such as dielectric elastomers, liquid-crystal polymers and piezoelectric polymers). This review is intended to serve as an introduction to the mechanisms of these materials and as a first step in material selection for both researchers and designers of flexible/bendable devices, biocompatible sensors or even robotic tactile sensing units.

Why START?

International Nuclear Information System (INIS)

Mendelsohn, J.

1991-01-01

Barring some major unexpected downturn in US-Soviet relations, it seems likely that the long-awaited Strategic Arms Reduction Talks (START) treaty will be signed sometime in 1991. Under negotiation for the past nine years, public acceptance and Senate approval of a START treaty will be facilitated by the generally less confrontational East-West relationship which has evolved over that time, by the growing constraints on the US defense budget, and by the obvious merits of the treaty itself. Not only will the nearly complete START treaty be an extremely useful and powerful arms control agreement, it is also decidedly advantageous to US security interests. First and foremost, a START treaty will cap and reduce the steady buildup of nuclear weapons that has characterized the last 30 years of the US-Soviet strategic relationship. As a result of the basic outline originally agreed to at the Reykjavik summit, START will take a 25 to 35 percent bite out of existing nuclear arsenals, impose approximately a 50 percent cut in overall Soviet ballistic missile warheads and throw-weight (lifting power or payload capacity), and produce an exact 50 percent cut in Soviet SS-18 missiles

Optical datasets from estuarine and coastal systems are increasingly available for remote sensing algorithm development, validation, and application. With validated algorithms, the data streams from satellite sensors can provide unprecedented spatial and temporal data for local and regional coastal water quality management. Our presentation will highlight two recent applications of optical data and remote sensing to water quality decision-making in coastal regions of the state of Florida; (1) informing the development of estuarine and coastal nutrient criteria for the state of Florida and (2) informing the rezoning of the Florida Keys National Marine Sanctuary. These efforts involved building up the underlying science to demonstrate the applicability of satellite data as well as an outreach component to educate decision-makers about the use, utility, and uncertainties of remote sensing data products. Scientific developments included testing existing algorithms and generating new algorithms for water clarity and chlorophylla in case II (CDOM or turbidity dominated) estuarine and coastal waters and demonstrating the accuracy of remote sensing data products in comparison to traditional field based measurements. Including members from decision-making organizations on the research team and interacting with decision-makers early and often in the process were key factors for the success of the outreach efforts and the eventual adoption of satellite data into the data records and analyses used in decision-making.

This thesis begins by describing how high-technology risks like nuclear power plant explosions intrude into people`s everyday consciousness through television news. It problematises the failure of the traditional concepts in the social sciences to measure the consequences of sense making of nuclear risks and examines the distinction between the concepts of risk communication and crisis information. The Chernobyl disaster is presented and its consequences for media research discussed. Media coverage of disasters is examined in detail. The research paradigm is considered from the epistemological and ontological distinctions and qualitative methods versus quantitative ones are discussed. The interview methodology is discussed and profile descriptions given of the fifteen respondents. These includes lay people, authorities and experts, and representatives of the media. The data are examined from an ontological approach, using constructivism as the research framework. The ontological analysis is based on the application of Heidegger`s existentiales as a scientific instrument. The epistemological approach is discussed by proceeding from Heidegger to Habermas` theory of the communicative action. Finally, the thesis concludes with a discussion of the theoretical basis and methods used. 264 refs., 1 fig., 4 tabs.

Satellite Remote Sensing: Aerosol Measurements

Science.gov (United States)

Kahn, Ralph A.

2013-01-01

Aerosols are solid or liquid particles suspended in the air, and those observed by satellite remote sensing are typically between about 0.05 and 10 microns in size. (Note that in traditional aerosol science, the term "aerosol" refers to both the particles and the medium in which they reside, whereas for remote sensing, the term commonly refers to the particles only. In this article, we adopt the remote-sensing definition.) They originate from a great diversity of sources, such as wildfires, volcanoes, soils and desert sands, breaking waves, natural biological activity, agricultural burning, cement production, and fossil fuel combustion. They typically remain in the atmosphere from several days to a week or more, and some travel great distances before returning to Earth's surface via gravitational settling or washout by precipitation. Many aerosol sources exhibit strong seasonal variability, and most experience inter-annual fluctuations. As such, the frequent, global coverage that space-based aerosol remote-sensing instruments can provide is making increasingly important contributions to regional and larger-scale aerosol studies.

The evolution of current Radiation and Nuclear Emergency Planning Framework (RANEPF) simulator emphasizes on the human factors to be analyzed and interpreted according to the stakeholder's tacit and explicit knowledge. These human factor criteria are analyzed and interpreted according to the "sense making theory" and Disaster Emergency Response Management Information System (DERMIS) design premises. These criteria are corroborated by the statistical criteria. In recent findings, there were no differences of distributions among the stakeholders according to gender and organizational expertise. These criteria are incrementally accepted and agreed the research elements indicated in the respective emergency planning frameworks and simulator (i.e. 78.18 to 84.32, p-value <0.05). This paper suggested these human factors criteria in the associated analyses and theoretical perspectives to be further acomodated in the future simulator development. This development is in conjunction with the proposed hypothesis building of the process factors and responses diagram. We proposed that future work which implies the additional functionality of the simulator, as strategized, condensed and concise, comprehensive public disaster preparedness and intervention guidelines, to be a useful and efficient computer simulation.

The nice people who live up in the cold place above you put lots of money into sense things to look into the big deep water and see weird-ass things

There is lots of stuff in the very big water we want to look at. But because our bodies are soft and can't hold air good, we use computer senses to help us look at all the stuff down there instead.It's actually really good thinking because we don't have to get wet and we can use computer senses under the water all the time, even when the air is cold and it sucks to be outside. We can also go really deep which is cool because weird-ass stuff is down there and we would get pressed too small if we tried to go in person. The sense things idea also save us lots of money because we only have to use other people's water cars once a year to make sure our sense things are working all the time and that we can still see stuff right. Our sense things are made of power lines that go out into the big water and come back to our work-house so if we don't want to keep looking at the same thing, we can tell the sense things to do it different from our house using the lines. This is pretty good because we can change our minds a lot and still get good ideas about what is happening in the big deep water where the weird-ass stuff is.Our head-guys give us money for this thing because we think it will let us know if the ground will shake and kill us before it starts shaking. This is kind of important because we can get out of the way and we can take our good stuff with us too if we know early that it will start shaking and making big-ass waves. Head-guys like to make people feel safe and we are good at helping with that, we think.But we made sure our sense thing can be used for more than just being ready to run away if the ground moves (even though this is a good use). There are also lots of weird-ass and weird-front animals in the big water. Some are not good looking at all, but they do cool stuff with their bodies or they are really good for eating and that makes them really interesting so we look at them too.Last but not least, we use our sense things up in the really cold big water

Making Sense of War and Peace

Mogensen, Kirsten

2016-01-01

When people tell stories about their past experiences, they often include descriptions that infer changes in trust repertoires over time, especially when the stories relate to serious life dramas like war and peace. A happy ending can make a past war appear meaningful. In this case study......, retrospective narratives summarizing fifty years of history in Aceh, Indonesia, were analyzed using Fuglsang’s & Jagd’s framework (2013). The concept spiritual trust is introduced, and the case study indicates that when neither institutions nor powers are strong enough to support trusting, trust in a divine...... power can provide an alternative framework for sensemaking and trusting. In Aceh, three decades of civil war ended with a peace process in 2005, and extreme distrust was then replaced by institutional trust. Insights from that process are of relevance for the study of trust-repair....

Large belt conveyors: starting them and keeping them going

2008-03-15

Although heavy-duty conveyor drives are subjected to some of the most severe operating conditions, it is still possible to achieve reliability and low maintenance. Some areas where choices in design and construction can make a difference include thermal capacity, sealing, lubrication and strength. Dodge recently brought out its redesigned Global Series 750 CST - controlled start transmission - a multi-stage gear reducer with an internal clutch designed for smooth starting of high inertia loads on long-distance conveyors. The Antelope Mine in Wyoming's Powder River Basin first installed Dodge CST units in 1984 and has added more units over the years. CSTs have also been successfully employed in Australian coal mines. 1 fig., 1 photo.

Horstman, Haley Kranstuber; Holman, Amanda

2017-08-28

Grounded in communicated sense-making (CSM) theorizing, we investigated communicated perspective-taking (CPT; i.e., conversational partners' attendance to and confirmation of each other's views) in association with individual and relational well-being in married couples who had miscarried (n = 183; N = 366). Actor-partner interdependence modeling revealed husbands' perceptions of wives' CPT were positively related to husbands' positive affect about the miscarriage and both spouses' relational satisfaction, as well as negatively associated with wives' positive affect. Wives' perceptions of husbands' CPT related positively to their own relational satisfaction and negatively to husbands' negative affect. Analyses revealed identification as a parent to the miscarried child (i.e., "parenting role salience") positively moderated the relationship between CPT and relational satisfaction. Implications for advancing CSM theorizing in health contexts and practical applications are explored.

Piezoelectric self sensing actuators for high voltage excitation

International Nuclear Information System (INIS)

Grasso, E; Totaro, N; Janocha, H; Naso, D

2013-01-01

Self sensing techniques allow the use of a piezoelectric transducer simultaneously as an actuator and as a sensor. Such techniques are based on knowledge of the transducer behaviour and on measurements of electrical quantities, in particular voltage and charge. Past research work has mainly considered the linear behaviour of piezoelectric transducers, consequently restricting the operating driving voltages to low values. In this work a new self sensing technique is proposed which is able to perform self sensing reconstruction both at low and at high driving voltages. This technique, in fact, makes use of a hysteretic model to describe the nonlinear piezoelectric capacitance necessary for self sensing reconstruction. The capacitance can be measured and identified at the antiresonances of a vibrating structure with a good approximation. After providing a mathematical background to deal with the main aspects of self sensing, this technique is compared theoretically and experimentally to a typical linear one by using an aluminum plate with one bonded self sensing transducer and a positive position feedback (PPF) controller to verify the performance in self sensing based vibration control.

The National Satellite Land Remote Sensing Data Archive (NSLRSDA) resides at the U.S. Geological Survey's (USGS) Earth Resources Observation and Science (EROS) Center. Through the Land Remote Sensing Policy Act of 1992, the U.S. Congress directed the Department of the Interior (DOI) to establish a permanent Government archive containing satellite remote sensing data of the Earth's land surface and to make this data easily accessible and readily available. This unique DOI/USGS archive provides a comprehensive, permanent, and impartial observational record of the planet's land surface obtained throughout more than five decades of satellite remote sensing. Satellite-derived data and information products are primary sources used to detect and understand changes such as deforestation, desertification, agricultural crop vigor, water quality, invasive plant species, and certain natural hazards such as flood extent and wildfire scars.

Remote Sensing of Environmental Pollution

Science.gov (United States)

North, G. W.

1971-01-01

Environmental pollution is a problem of international scope and concern. It can be subdivided into problems relating to water, air, or land pollution. Many of the problems in these three categories lend themselves to study and possible solution by remote sensing. Through the use of remote sensing systems and techniques, it is possible to detect and monitor, and in some cases, identify, measure, and study the effects of various environmental pollutants. As a guide for making decisions regarding the use of remote sensors for pollution studies, a special five-dimensional sensor/applications matrix has been designed. The matrix defines an environmental goal, ranks the various remote sensing objectives in terms of their ability to assist in solving environmental problems, lists the environmental problems, ranks the sensors that can be used for collecting data on each problem, and finally ranks the sensor platform options that are currently available.

Securing Collaborative Spectrum Sensing against Untrustworthy Secondary Users in Cognitive Radio Networks

Science.gov (United States)

Wang, Wenkai; Li, Husheng; Sun, Yan(Lindsay); Han, Zhu

2009-12-01

Cognitive radio is a revolutionary paradigm to migrate the spectrum scarcity problem in wireless networks. In cognitive radio networks, collaborative spectrum sensing is considered as an effective method to improve the performance of primary user detection. For current collaborative spectrum sensing schemes, secondary users are usually assumed to report their sensing information honestly. However, compromised nodes can send false sensing information to mislead the system. In this paper, we study the detection of untrustworthy secondary users in cognitive radio networks. We first analyze the case when there is only one compromised node in collaborative spectrum sensing schemes. Then we investigate the scenario that there are multiple compromised nodes. Defense schemes are proposed to detect malicious nodes according to their reporting histories. We calculate the suspicious level of all nodes based on their reports. The reports from nodes with high suspicious levels will be excluded in decision-making. Compared with existing defense methods, the proposed scheme can effectively differentiate malicious nodes and honest nodes. As a result, it can significantly improve the performance of collaborative sensing. For example, when there are 10 secondary users, with the primary user detection rate being equal to 0.99, one malicious user can make the false alarm rate [InlineEquation not available: see fulltext.] increase to 72%. The proposed scheme can reduce it to 5%. Two malicious users can make [InlineEquation not available: see fulltext.] increase to 85% and the proposed scheme reduces it to 8%.

Crowdsensing in Smart Cities: Overview, Platforms, and Environment Sensing Issues

Directory of Open Access Journals (Sweden)

Oscar Alvear

2018-02-01

Full Text Available Evidence shows that Smart Cities are starting to materialise in our lives through the gradual introduction of the Internet of Things (IoT paradigm. In this scope, crowdsensing emerges as a powerful solution to address environmental monitoring, allowing to control air pollution levels in crowded urban areas in a distributed, collaborative, inexpensive and accurate manner. However, even though technology is already available, such environmental sensing devices have not yet reached consumers. In this paper, we present an analysis of candidate technologies for crowdsensing architectures, along with the requirements for empowering users with air monitoring capabilities. Specifically, we start by providing an overview of the most relevant IoT architectures and protocols. Then, we present the general design of an off-the-shelf mobile environmental sensor able to cope with air quality monitoring requirements; we explore different hardware options to develop the desired sensing unit using readily available devices, discussing the main technical issues associated with each option, thereby opening new opportunities in terms of environmental monitoring programs.

The start up as a phase of architectural design process.

Science.gov (United States)

Castro, Iara Sousa; Lima, Francisco de Paula Antunes; Duarte, Francisco José de Castro Moura

2012-01-01

Alterations made in the architectural design can be considered as a continuous process, from its conception to the moment a built environment is already in use. This article focuses on the "moving phase", which is the initial moment of the environment occupation and the start-up of services. It aims to show that the continuity of ergonomics interventions during the "moving phase" or start up may reveal the built environment inadequacies; clearly showing needs not met by the design and allowing making instant decisions to solve non-foreseen problems. The results have revealed some lessons experienced by users during a critical stage not usually included in the design process.

Key parameters of the swimming start and their relationship to start performance.

Science.gov (United States)

Tor, Elaine; Pease, David L; Ball, Kevin A

2015-01-01

The swimming start is typically broken into three sub-phases; on-block, flight, and underwater phases. While overall start performance is highly important to elite swimming, the contribution of each phase and important technical components within each phase, particularly with the new kick-start technique, has not been established. The aim of this study was to identify technical factors associated with overall start performance, with a particular focus on the underwater phase. A number of parameters were calculated from 52 starts performed by elite freestyle and butterfly swimmers. These parameters were split into above-water and underwater groupings, before factor analysis was used to reduce parameter numbers for multiple regression. For the above-water phases, 81% of variance in start performance was accounted for by take-off horizontal velocity. For the underwater water phase, 96% of variance was accounted for with time underwater in descent, time underwater in ascent and time to 10 m. Therefore, developing greater take-off horizontal velocity and focussing on the underwater phase by finding the ideal trajectory will lead to improved start performance.

Becoming a normal guy: Men making sense of long-term bodily changes following bariatric surgery.

Science.gov (United States)

Groven, Karen Synne; Galdas, Paul; Solbrække, Kari Nyheim

2015-01-01

To date, research on bodily changes following bariatric surgery has focused predominantly on women, leaving the long-term experience of men relatively unexplored. In this paper, we draw on interviews with men who have undergone an irreversible gastric bypass procedure to explore their bodily changes more than 4 years post-surgery. We apply a phenomenological framework that draws on Leder's perspectives on the "disappearing" and "dys-appearing" body, combined with a gender-sensitive lens that draws on Connell's theory of hegemonic masculinity and Robertson's conceptions of embodied masculinity. Our principal finding was that the men negotiated their bodily changes following bariatric surgery in profoundly ambivalent ways. Although they enthusiastically praised the surgery for improving their health, self-esteem, and social functioning, they also emphasized their efforts to cope with post-surgical side effects and life-threatening complications. Our analysis elaborates on their efforts to adjust to and come to terms with these changes, focusing on episodes of hypoglycemia, severe pain and internal herniation, and the significance of physical activity and exercise. Our findings point to the need to acknowledge men's ways of making sense of profound and ongoing bodily changes following bariatric surgery and how these negotiations are closely intertwined with masculine ideals of embodiment and social value.

Modeling Common-Sense Decisions

Science.gov (United States)

Zak, Michail

This paper presents a methodology for efficient synthesis of dynamical model simulating a common-sense decision making process. The approach is based upon the extension of the physics' First Principles that includes behavior of living systems. The new architecture consists of motor dynamics simulating actual behavior of the object, and mental dynamics representing evolution of the corresponding knowledge-base and incorporating it in the form of information flows into the motor dynamics. The autonomy of the decision making process is achieved by a feedback from mental to motor dynamics. This feedback replaces unavailable external information by an internal knowledgebase stored in the mental model in the form of probability distributions.

Does the Common Agricultural Policy still make sense in the twenty-first century? CAP after 2013 from the perspective of Poland and Hungary

Directory of Open Access Journals (Sweden)

Elżbieta Daszkowska

2009-01-01

Full Text Available The EU CAP has developed immensely since the 1960’s. However, its current determinants are completely different from those which formed the CAP foundations. This results mainly from the fact that the UE CAP must meet present-day challenges and threats. Moreover, further EU enlargements also significantly influenced performance of this sector of economy. It is important to determine whether the existence of the CAP in the twenty-first century still makes sense and to specify in more detail the CAP reform directions after 2013 from the perspective of Poland and Hungary.

A shared experience of fragmentation: making sense of foster placement breakdown.

Science.gov (United States)

Rostill-Brookes, Helen; Larkin, Michael; Toms, Amy; Churchman, Clare

2011-01-01

Multiple placement transitions have been associated with poorer psychosocial outcomes for children growing up in local authority care. However, although there is an expanding literature examining the risk and protective factors connected with placement breakdown, very few studies have explored the quality of the move experience for those most closely involved with it. Our study considered how young people, foster carers and social workers made sense of unplanned placements' endings. Bringing together the lived experiences of these key stakeholders in the placement system added a novel dimension to existing research knowledge. What emerged from our analysis was evidence of a pervasive and shared emotional experience; all of the participants were affected by the breakdown irrespective of age, experience, or professional role. However, despite many commonalities, there was also a strong sense of fragmentation between the groups, which was characterised by discourses of mistrust and miscommunication. This meant that emotional reactions to the breakdown were often suppressed or dismissed, resentments built-up and attempts to find a solution were thwarted by silence or angry recrimination. These findings raise real challenges for practice and policy development. In particular, they stress the importance of shared and meaningful dialogue between all key stakeholders within the social care system, the need for more effective and timely support when placements are in crisis and opportunities for those most closely involved with the placement breakdown to process the emotional experience.

Enabling Virtual Sensing as a Service

Directory of Open Access Journals (Sweden)

Yang Li

2016-03-01

Full Text Available In many situations, placing a physical sensor in the ideal position in or on the human body to acquire sensing data is incredibly difficult. Virtual sensors, in contrast to physical sensors, can provide indirect measurements by making use of other available sensor data. In this paper, we demonstrate a virtual sensing application developed as a service on top of a cloud-based health sensor data management platform called Wiki-Health. The proposed application “implants” virtual sensors in the human body by integrating environmental, geographic and personal sensor data with physiological models to compute temperature estimations of various parts of the body. The feasibility of the proposed virtual sensing service is supported by a case study. The ability to share computational models relevant to do calculations on measured data on the go is also discussed.

Full Text Available Like all great religions of the world, Christianity is a religion steeped in revelation. It tries to convince its followers that it was through the process of revelation that God made Himself known both in the Old and New Testaments, climaxing in the saving action of Jesus Christ. Although this is the starting point of Christian revelation, it would surprise many to know that it was only in the last five centuries that Christians started debating the issue and nature of revelation. In the present article, we shall critically examine how Catholic Christians started perceiving the notion of revelation from the Second Vatican Council (1962-1965 as enshrined in the Constitution Dei Verbum of the Council and the issues that keep Catholics engaged with regard to it with particular focus upon the relation between Scripture and Tradition and the ensuing tensions.

The current status of artificial intelligence AI technology is discussed along with imagery data management, database interrogation, and decision making. Techniques adapted from the field of artificial intelligence (AI) have significant, wide ranging impacts upon computer-assisted remote sensing analysis. AI based techniques offer a powerful and fundamentally different approach to many remote sensing tasks. In addition to computer assisted analysis, AI techniques can also aid onboard spacecraft data processing and analysis and database access and query.

This is Part 1 of two articles demonstrating the relevance of business ethics to nurse administrators as they confront value-laden issues such as the advantages and disadvantages of 10-12-hour scheduling patterns, understaffing, emerging registered nurse partnerships, and other administrative problems. Common-sense ethics can serve as the basis of just administrative decisions. The authors present a model of preparatory attitudes and behaviors. The steps that they propose do not guarantee success, but if implemented, they may facilitate the nurse administrator's management of diverse ethical issues.

Intelligent sensing and control of gas metal arc welding

International Nuclear Information System (INIS)

Smartt, H.B.; Johnson, J.A.

1993-01-01

Intelligent sensing and control is a multidisciplinary approach that attempts to build adequate sensing capability, knowledge of process physics, control capability, and welding engineering into the welding system such that the welding machine is aware of the state of the weld and knows how to make a good weld. The sensing and control technology should reduce the burden on the welder and welding engineer while providing the great adaptability needed to accommodate the variability found in the production world. This approach, accomplished with application of AI techniques, breaks the tradition of separate development of procedure and control technology

Bootstrap finance: the art of start-ups.

Science.gov (United States)

Bhide, A

1992-01-01

Entrepreneurship is more popular than ever: courses are full, policymakers emphasize new ventures, managers yearn to go off on their own. Would-be founders often misplace their energies, however. Believing in a "big money" model of entrepreneurship, they spend a lot of time trying to attract investors instead of using wits and hustle to get their ideas off the ground. A study of 100 of the 1989 Inc. "500" list of fastest growing U.S. start-ups attests to the value of bootstrapping. In fact, what it takes to start a business often conflicts with what venture capitalists require. Investors prefer solid plans, well-defined markets, and track records. Entrepreneurs are heavy on energy and enthusiasm but may be short on credentials. They thrive in rapidly changing environments where uncertain prospects may scare off established companies. Rolling with the punches is often more important than formal plans. Striving to adhere to investors' criteria can diminish the flexibility--the try-it, fix-it approach--an entrepreneur needs to make a new venture work. Seven principles are basic for successful start-ups: get operational fast; look for quick break-even, cash-generating projects; offer high-value products or services that can sustain direct personal selling; don't try to hire the crack team; keep growth in check; focus on cash; and cultivate banks early. Growth and change are the start-up's natural environment. But change is also the reward for success: just as ventures grow, their founders usually have to take a fresh look at everything again: roles, organization, even the very policies that got the business up and running.

Compressed Sensing Methods in Radio Receivers Exposed to Noise and Interference

DEFF Research Database (Denmark)

Pierzchlewski, Jacek

, there is a problem of interference, which makes digitization of radio receivers even more dicult. High-order low-pass lters are needed to remove interfering signals and secure a high-quality reception. In the mid-2000s a new method of signal acquisition, called compressed sensing, emerged. Compressed sensing...... the downconverted baseband signal and interference, may be replaced by low-order lters. Additional digital signal processing is a price to pay for this feature. Hence, the signal processing is moved from the analog to the digital domain. Filtering compressed sensing, which is a new application of compressed sensing...

Social Sensor Analytics: Making Sense of Network Models in Social Media

Energy Technology Data Exchange (ETDEWEB)

Dowling, Chase P.; Harrison, Joshua J.; Sathanur, Arun V.; Sego, Landon H.; Corley, Courtney D.

2015-07-27

Social networks can be thought of as noisy sensor networks mapping real world information to the web. Owing to the extensive body of literature in sensor network analysis, this work sought to apply several novel and traditional methods in sensor network analysis for the purposes of efficiently interrogating social media data streams from raw data. We carefully revisit our definition of a social media signal from previous work both in terms of time-varying features within the data and the networked nature of the medium. Further, we detail our analysis of global patterns in Twitter over the months of November 2013 and June 2014, detect and categorize events, and illustrate how these analyses can be used to inform graph-based models of Twitter, namely using a recent network influence model called PhySense: similar to PageRank but tuned to behavioral analysis by leveraging a sociologically inspired probabilistic model. We ultimately identify forms of information dissemination via analysis of time series and dynamic graph spectra and corroborate these findings through manual investigation of the data as a requisite step in modeling the diffusion process with PhySense. We hope to sufficiently characterize global behavior in a medium such as Twitter as a means of learning global model parameters one may use to predict or simulate behavior on a large scale. We have made our time series and dynamic graph analytical code available via a GitHub repository https://github.com/cpatdowling/salsa and our data are available upon request.

reconfigurable radio frequency (RF parts, enhanced spectrum sensing algorithms, and sophisticated machine learning techniques. In this paper, we present a review of the recent advances in CR transceivers hardware design and algorithms. For the RF part, three types of antennas are presented: UWB antennas, frequency-reconfigurable/tunable antennas, and UWB antennas with reconfigurable band notches. The main challenges faced by the design of the other RF blocks are also discussed. Sophisticated spectrum sensing algorithms that overcome main sensing challenges such as model uncertainty, hardware impairments, and wideband sensing are highlighted. The cognitive engine features are discussed. Moreover, we study unsupervised classification algorithms and a reinforcement learning (RL algorithm that has been proposed to perform decision-making in CR networks.

Concept of subsurface micro-sensing; Chika joho no micro sensing

Energy Technology Data Exchange (ETDEWEB)

Niitsuma, H [Tohoku University, Sendai (Japan). Faculty of Engineering

1997-05-27

This paper describes concept of subsurface micro-sensing. It is intended to achieve an epoch-making development of subsurface engineerings by developing such technologies as micro measurement of well interior, micro measurement while drilling (MWD), and micro intelligent logging. These technologies are supported by development of micro sensors and micro drilling techniques using micro machine technologies. Micronizing the subsurface sensors makes mass production of sensors with equivalent performance possible, and the production cost can be reduced largely. The sensors can be embedded or used disposably, resulting in increased mobility in measurement and higher performance. Installing multiple number of sensors makes high-accuracy measurement possible, such as array measurement. The sensors can be linked easily with photo-electronics components, realizing remote measurement at low price and high accuracy. Control in micro-drilling and MWD also become possible. Such advantages may also be expected as installing the sensors on the outer side of wells in use and monitoring subsurface information during production. Expectation on them is large as a new paradigm of underground exploration and measurement. 1 fig.

RF Spectrum Sensing Based on an Overdamped Nonlinear Oscillator Ring for Cognitive Radios

Directory of Open Access Journals (Sweden)

Zhi-Ling Tang

2016-06-01

Full Text Available Existing spectrum-sensing techniques for cognitive radios require an analog-to-digital converter (ADC to work at high dynamic range and a high sampling rate, resulting in high cost. Therefore, in this paper, a spectrum-sensing method based on a unidirectionally coupled, overdamped nonlinear oscillator ring is proposed. First, the numerical model of such a system is established based on the circuit of the nonlinear oscillator. Through numerical analysis of the model, the critical condition of the system’s starting oscillation is determined, and the simulation results of the system’s response to Gaussian white noise and periodic signal are presented. The results show that once the radio signal is input into the system, it starts oscillating when in the critical region, and the oscillating frequency of each element is fo/N, where fo is the frequency of the radio signal and N is the number of elements in the ring. The oscillation indicates that the spectrum resources at fo are occupied. At the same time, the sampling rate required for an ADC is reduced to the original value, 1/N. A prototypical circuit to verify the functionality of the system is designed, and the sensing bandwidth of the system is measured.

2013-01-01

A fully integrated soft-start circuit for DC—DC buck converters is presented. The proposed high speed soft-start circuit is made of two sections: an overshoot suppression circuit and an inrush current suppression circuit. The overshoot suppression circuit is presented to control the input of the error amplifier to make output voltage limit increase in steps without using an external capacitor. A variable clock signal is adopted in the inrush current suppression circuit to increase the duty cycle of the system and suppress the inrush current. The DC—DC converter with the proposed soft-start circuit has been fabricated with a standard 0.13 μm CMOS process. Experimental results show that the proposed high speed soft-start circuit has achieved less than 50 μs start-up time. The inductor current and the output voltage increase smoothly over the whole load range. (semiconductor integrated circuits)

The role of advanced sensing in smart cities.

Hancke, Gerhard P; Silva, Bruno de Carvalho E; Hancke, Gerhard P

2012-12-27

In a world where resources are scarce and urban areas consume the vast majority of these resources, it is vital to make cities greener and more sustainable. Advanced systems to improve and automate processes within a city will play a leading role in smart cities. From smart design of buildings, which capture rain water for later use, to intelligent control systems, which can monitor infrastructures autonomously, the possible improvements enabled by sensing technologies are immense. Ubiquitous sensing poses numerous challenges, which are of a technological or social nature. This paper presents an overview of the state of the art with regards to sensing in smart cities. Topics include sensing applications in smart cities, sensing platforms and technical challenges associated with these technologies. In an effort to provide a holistic view of how sensing technologies play a role in smart cities, a range of applications and technical challenges associated with these applications are discussed. As some of these applications and technologies belong to different disciplines, the material presented in this paper attempts to bridge these to provide a broad overview, which can be of help to researchers and developers in understanding how advanced sensing can play a role in smart cities.

A qualitative study of women's decision-making at the end of IVF treatment.

Science.gov (United States)

Peddie, V L; van Teijlingen, E; Bhattacharya, S

2005-07-01

The decision not to pursue further in vitro fertilization (IVF) after one or more unsuccessful attempts is an important and often difficult one for couples. Relatively little is known about the woman's perception of this decision-making process. The aim of this study was to examine patients' perspectives of decision-making, including circumstances influencing it and satisfaction with the decision-making process. Semi-structured interviews were conducted with a purposive sample of 25 women who had decided to end treatment after unsuccessful IVF treatment. Interviews were tape-recorded and transcribed by means of thematic analysis using the open coding technique. Women experienced difficulty in accepting that their infertility would remain unresolved. Many felt that they had started with unrealistic expectations of treatment success and felt vulnerable to the pressures of both the media and society. Although the decision to end treatment was difficult, it offered many women a way out of the emotional distress caused by IVF; however, the process of decision-making created a sense of 'confrontation' for the women in which they had to address issues they had previously avoided. Adoptive parents perceived less societal pressure than those who remained childless. Efforts to improve the psychological preparation of couples who decide to end IVF treatment should be directed towards examination of the existing system of consultation, which has certain limitations in terms of the quality of communication and the provision of post-treatment support. Further efforts to develop strategies, which facilitate the decision-making process, should be considered.

Becoming a normal guy: Men making sense of long-term bodily changes following bariatric surgery

Directory of Open Access Journals (Sweden)

Karen Synne Groven

2015-12-01

Full Text Available Background: To date, research on bodily changes following bariatric surgery has focused predominantly on women, leaving the long-term experience of men relatively unexplored. In this paper, we draw on interviews with men who have undergone an irreversible gastric bypass procedure to explore their bodily changes more than 4 years post-surgery. We apply a phenomenological framework that draws on Leder's perspectives on the “disappearing” and “dys-appearing” body, combined with a gender-sensitive lens that draws on Connell's theory of hegemonic masculinity and Robertson's conceptions of embodied masculinity. Findings: Our principal finding was that the men negotiated their bodily changes following bariatric surgery in profoundly ambivalent ways. Although they enthusiastically praised the surgery for improving their health, self-esteem, and social functioning, they also emphasized their efforts to cope with post-surgical side effects and life-threatening complications. Our analysis elaborates on their efforts to adjust to and come to terms with these changes, focusing on episodes of hypoglycemia, severe pain and internal herniation, and the significance of physical activity and exercise. Conclusions: Our findings point to the need to acknowledge men's ways of making sense of profound and ongoing bodily changes following bariatric surgery and how these negotiations are closely intertwined with masculine ideals of embodiment and social value.

Start-up Strategy for Continuous Bioreactors

Directory of Open Access Journals (Sweden)

A.C. da Costa

1997-06-01

Full Text Available Abstract - The start-up of continuous bioreactors is solved as an optimal control problem. The choice of the dilution rate as the control variable reduces the dimension of the system by making the use of the global balance equation unnecessary for the solution of the optimization problem. Therefore, for systems described by four or less mass balance equations, it is always possible to obtain an analytical expression for the singular arc as a function of only the state variables. The steady state conditions are shown to satisfy the singular arc expression and, based on this knowledge, a feeding strategy is proposed which leads the reactor from an initial state to the steady state of maximum productivity

2013-12-01

Full Text Available This paper presents a PhD-course called "Kick start to academic life - Information Management and Publication Process for Social Scientists", a collaboration between the Social Sciences Faculty Library at Lund University and professors at the Faculty. The objective of the course is to provide PhD candidates with generic knowledge about how to effectively conduct their PhD studies when it comes to information management and the publication processes. The course combines an introduction to the process of managing one's need of information as a PhD student, and an introduction to the process of managing the publication of one's results. The librarians have been involved in the development of this PhD course, from the first idea of a course in generic competences and on to the actual implementation. The Faculty of Social Science came up with the idea of a course like this in 2009, and asked two teachers/professors and two librarians to make an outline. We choose to focus on students in the beginning of their PhD studies, who would benefit most from it. We have now run it for 3 years (2010-2012, developed the course as for content and size, from demands from students and faculty as well as from our own experiences. Designing the course together, librarians and professors gained an insight into each other's competences and area of expertise. We used previous experiences from working with PhD students, like the providing of shorter courses, seminars and workshops. We choose a course design mixing lectures and workshops, in order to make the course both theoretical and practical. The course design also helped emphasizing aspects of the subject being discussed. One example is by adding a practical workshop in reference management program given by the librarians just after a lecture given by a professor about how and why academics cite. Another example is when we invite an editor of a high ranked peer-reviewed journal to talk about article submission from

A flexible capacitive tactile sensing array with floating electrodes

International Nuclear Information System (INIS)

Cheng, M-Y; Huang, X-H; Ma, C-W; Yang, Y-J

2009-01-01

In this work, we present the development of a capacitive tactile sensing array realized by using MEMS fabrication techniques and flexible printed circuit board (FPCB) technologies. The sensing array, which consists of two micromachined polydimethlysiloxane (PDMS) structures and a FPCB, will be used as the artificial skin for robot applications. Each capacitive sensing element comprises two sensing electrodes and a common floating electrode. The sensing electrodes and the metal interconnect for signal scanning are implemented on the FPCB, while the floating electrode is patterned on one of the PDMS structures. This special design can effectively reduce the complexity of the device structure and thus makes the device highly manufacturable. The characteristics of the devices with different dimensions are measured and discussed. The corresponding scanning circuits are also designed and implemented. The tactile images induced by the PMMA stamps of different shapes are also successfully captured by a fabricated 8 × 8 array

Enhancing Sensing and Channel Access in Cognitive Radio Networks

KAUST Repository

Hamza, Doha R.

2014-06-18

Cognitive radio technology is a promising technology to solve the wireless spectrum scarcity problem by intelligently allowing secondary, or unlicensed, users access to the primary, licensed, users\\' frequency bands. Cognitive technology involves two main tasks: 1) sensing the wireless medium to assess the presence of the primary users and 2) designing secondary spectrum access techniques that maximize the secondary users\\' benefits while maintaining the primary users\\' privileged status. On the spectrum sensing side, we make two contributions. First, we maximize a utility function representing the secondary throughput while constraining the collision probability with the primary below a certain value. We optimize therein the channel sensing time, the sensing decision threshold, the channel probing time, together with the channel sensing order for wideband primary channels. Second, we design a cooperative spectrum sensing technique termed sensing with equal gain combining whereby cognitive radios simultaneously transmit their sensing results to the fusion center over multipath fading reporting channels. The proposed scheme is shown to outperform orthogonal reporting systems in terms of achievable secondary throughput and to be robust against phase and synchronization errors. On the spectrum access side, we make four contributions. First, we design a secondary scheduling scheme with the goal of minimizing the secondary queueing delay under constraints on the average secondary transmit power and the maximum tolerable primary outage probability. Second, we design another secondary scheduling scheme based on the spectrum sensing results and the primary automatic repeat request feedback. The optimal medium access probabilities are obtained via maximizing the secondary throughput subject to constraints that guarantee quality of service parameters for the primary. Third, we propose a three-message superposition coding scheme to maximize the secondary throughput without

2014-04-01

Full Text Available Number sense involves efficient strategies and the ability to think flexibly with numbers and number operations and flexible thinking ability and the inclination getting for making sound mathematical judgements. The aim of this study was to investigate the strategies used by mathematics teachers while solving number sense problems. Eleven mathematics teachers from a graduate program in education were the participants. A number sense test which has a total of 12 problems is used as the data gathering tool. Teachers’ responses and strategies were analyzed both qualitatively and quantitatively.First, participants’ responses were evaluated for correctness. Then the strategies teachers used were analyzed. The strategies were categorized as based on the use of number sense or rule based strategies. When the correct and incorrect responses were considered together, in the 46% of the responses number sense strategies were used and in 54% the rule-based strategies were used. The results of this study showed that even though teachers can use number sense strategies at some level, there is still room for development in teachers’ number sense.

Dahiya, Ravinder S

2013-01-01

Future robots are expected to work closely and interact safely with real-world objects and humans alike. Sense of touch is important in this context, as it helps estimate properties such as shape, texture, hardness, material type and many more; provides action related information, such as slip detection; and helps carrying out actions such as rolling an object between fingers without dropping it. This book presents an in-depth description of the solutions available for gathering tactile data, obtaining aforementioned tactile information from the data and effectively using the same in various robotic tasks. Better integration of tactile sensors on a robot’s body is prerequisite for the effective utilization of tactile data. For this reason, the hardware, software and application related issues (and resulting trade-offs) that must be considered to make tactile sensing an effective component of robotic platforms are discussed in-depth.To this end, human touch sensing has also been explored. The design hints co...

It eats power station waste for breakfast, but has E-Crete got what it takes to replace ordinary concrete? Zeobond, a company in Melbourne, Australia is due to start transforming waste from power stations and blast furnaces into geopolymer concrete, releasing just 10 to 20% of the greenhouse gases associated with making traditional concrete. The starting materials for the novel E-crete are silicon- and oxygen-containing silicates and aluminium and oxygen-containing aluminates both of which are present in fly ash and slag waste. These undergo polymerization to a geopolymer when alkali is added, producing no CO{sub 2} and requiring no heating. Zeobond is the first company to start making geopolymers commercially for construction projects. Tests show they are just as strong as ordinary concrete but it is not yet clear that they are as durable. 1 fig., 1 photo.

To examine how adolescent-parent dyads describe decision-making regarding initiation of the human papillomavirus (HPV) vaccine series, specifically who they viewed as making the final decision. Semistructured interviews with adolescent-parent dyads were audio-recorded and transcribed. Responses to the question: "How did you make a decision about whether or not to receive the HPV vaccine series?" were content-coded for each individual member of the dyad. Adolescent medicine clinics of 2 large urban medical centers and through snowball sampling. Adolescents 14-17 years of age and a parent (N = 262). Qualitative analyses were conducted for those who agreed that they were offered and started the HPV vaccine series (n = 109). None. Descriptions of the decision-making included 1 person (adolescent or parent) making the decision or joint decision-making by the adolescent and parent together. More than half of the dyads did not agree on who made the decision to start the vaccine. Most adolescents and parents described a similar account about when they were offered the HPV vaccine, although the interpretation of the event in terms of the decision-maker might have differed. More than half of adolescents and parents individually mentioned the health care provider in their description of the HPV vaccine decision-making process even though they were not queried about the role of the provider. Understanding the range of descriptions of these dyads is helpful to guide interventions to promote vaccine uptake in a manner that balances provider expertise, adolescent autonomy, and parental involvement.

STARTing Again: What Happens After START I Expires?

International Nuclear Information System (INIS)

Mladineo, Stephen V.; Durbin, Karyn R.; Eastman, Christina M.

2007-01-01

The Strategic Arms Reduction Treaty (START I), a seminal arms control agreement that substantially reduced the levels of deployed strategic nuclear arms in the United States and Russia, will expire in December 2009. At this time, it is unclear what - if anything - will replace it. While the treaty remains relevant, more than a simple extension is appropriate. Instead the authors advocate for a successor regime that builds on the START I legacy but does not rely on the traditional tools of arms control. This paper examines the strategic context in which a successor regime would be developed and proposes several recommendations for future action

Which goals are driving the Energiewende? Making sense of the German Energy Transformation

International Nuclear Information System (INIS)

Joas, Fabian; Pahle, Michael; Flachsland, Christian; Joas, Amani

2016-01-01

In 2010, Germany agreed a plan to increase the share of renewables in power consumption to 80% by 2050, and in 2011 the decision was taken to phase-out nuclear power by 2022. This policy is now widely known as the “Energiewende”. While many global observers consider this program to be primarily driven by the need to tackle climate change, the precise political goals of the Energiewende are, by and large, unclear. In our study we compiled a list of 14 goals put forward in political debates and conducted a “mapping” survey among more than 50 policy experts. We asked them to prioritize the goals based on their personal views and provide arguments for their rankings in ensuing interviews. Our main findings are as follows: (i) a large majority named climate protection among the top-level goals of the Energiewende; at the same time, around 80% of all participants also identified additional goals; (ii) when asked if the Energiewende would make sense even if climate change did not exist, two thirds of the participants agreed, which, when taken with the first finding, demonstrates that the goals and motivations driving the Energiewende are more complex than often assumed. We conclude that for the sake of effective and efficient policies and ever rising climate policy ambition, a public debate and clear specification of the top-level goals are indispensable. - Highlights: •We examine the goals of German energy policy called the “Energiewende”. •We show that policy experts relate up to 14 goals with the Energiewende. •So far the political goals of the Energiewende, and especially their ranking is unclear. •We call for a public debate and a clear specification of the top-level goals of the Energiewende.

Across the globe, planners and decision makers are often hampered by organizational and data silos and/or a lack of historic data or scant in situ observations on which to base policy and action plans. The end result is a complex interaction of responsibilities, legal frameworks, and stakeholder needs guided by uncertain information that is essentially bounded by how climate extremes are defined and characterized. Because of the importance of water, considerable resources in the developing and developed world are invested in data and tools for managing water. However, the existing paradigm of water management around the world faces significant challenges including inadequate funding to install, maintain or upgrade monitoring networks, lack of resources to integrate new science and data sources into existing tools, and demands for improved spatial coverage of observations. Add to this, a changing hydrology that is so complex it requires measurements and analyses that have never been done before. Interest in applying remote sensing science and observations into the decision making process is growing the world over, but in order to succeed, it is essential to form partnerships with stakeholder organizations and decision makers at the outset. In this talk, we describe examples of succesful decision-maker and science partnering based on projects that apply remote sensing science and observations in East Africa and the Lower Mekong Basin supported by the SERVIR Initiative, a joint United States Agency for International Development (USAID) and National Aeronautics and Space Administration (NASA) program, and projects in the western United States supported by NASA's Jet Propulsion Laboratory and the Western Water Applications Office (WWAO). All of these examples have benefitted from strong, committed partnerships with end user agencies. Best practices and lessons learned in connecting science to decision making amongst these examples are explored.

2017-10-01

We demonstrate a facile synthetic method to prepare lateral size controlled molybdenum diselenide (MoSe2) nanosheets using liquid phase exfoliated few-layer MoSe2 nanosheets as a starting material. By precisely controlling the centrifugation condition, preparation of MoSe2 nanosheets with a narrow size distribution ranging from several hundred nanometers to several micrometers could be realized. The accurate size control of MoSe2 nanosheets offers us a great opportunity to examine the size dependent sensing properties. The sensing test results demonstrate that the MoSe2 nanosheets provide competitive advantages compared with conventional graphene based sensors. A tradeoff phenomenon on sensing response and recovery as the lateral size of MoSe2 nanosheets varies is observed. First principles calculations reveal that the ratio of edge-surface sites is responsible for this phenomenon. The correlation between the lateral size and gas sensing performance of MoSe2 nanosheets is established.

Coping plays an essential role in maintaining the wellbeing of patients with cancer. A number of different coping responses and strategies have been identified in the literature. The value and relevance of meaning based coping theory has also been emphasised, including Antonovosky's Sense of Coherence (SoC) theory. Ten patients with advanced lung cancer were interviewed up to three times. A total of twenty in depth interviews were carried out, fully transcribed and data were analysed following a methodology of Interpretative Phenomenological Analysis. Three broad domains were identified to categorise the core life concerns of participants; making sense of and managing one's illness; maintaining daily life and relationships and confronting the future. Within these domains multiple coping themes are identified, which to varying degrees help to maintain patient wellbeing and quality of life. This article considers the relevance of SoC theory for understanding the coping experiences of patients with advanced cancer, and identifies resources and factors likely to support patient coping, with implications for health and social care services. © 2017 The Authors.

Correlation of neural activity with behavioral kinematics reveals distinct sensory encoding and evidence accumulation processes during active tactile sensing.

Science.gov (United States)

Delis, Ioannis; Dmochowski, Jacek P; Sajda, Paul; Wang, Qi

2018-03-23

Many real-world decisions rely on active sensing, a dynamic process for directing our sensors (e.g. eyes or fingers) across a stimulus to maximize information gain. Though ecologically pervasive, limited work has focused on identifying neural correlates of the active sensing process. In tactile perception, we often make decisions about an object/surface by actively exploring its shape/texture. Here we investigate the neural correlates of active tactile decision-making by simultaneously measuring electroencephalography (EEG) and finger kinematics while subjects interrogated a haptic surface to make perceptual judgments. Since sensorimotor behavior underlies decision formation in active sensing tasks, we hypothesized that the neural correlates of decision-related processes would be detectable by relating active sensing to neural activity. Novel brain-behavior correlation analysis revealed that three distinct EEG components, localizing to right-lateralized occipital cortex (LOC), middle frontal gyrus (MFG), and supplementary motor area (SMA), respectively, were coupled with active sensing as their activity significantly correlated with finger kinematics. To probe the functional role of these components, we fit their single-trial-couplings to decision-making performance using a hierarchical-drift-diffusion-model (HDDM), revealing that the LOC modulated the encoding of the tactile stimulus whereas the MFG predicted the rate of information integration towards a choice. Interestingly, the MFG disappeared from components uncovered from control subjects performing active sensing but not required to make perceptual decisions. By uncovering the neural correlates of distinct stimulus encoding and evidence accumulation processes, this study delineated, for the first time, the functional role of cortical areas in active tactile decision-making.

2018-01-01

As a part of the ELIXIR-EXCELERATE efforts in capacity building, we present here 10 steps to facilitate researchers getting started in genome assembly and genome annotation. The guidelines given are broadly applicable, intended to be stable over time, and cover all aspects from start to finish of a general assembly and annotation project. Intrinsic properties of genomes are discussed, as is the importance of using high quality DNA. Different sequencing technologies and generally applicable workflows for genome assembly are also detailed. We cover structural and functional annotation and encourage readers to also annotate transposable elements, something that is often omitted from annotation workflows. The importance of data management is stressed, and we give advice on where to submit data and how to make your results Findable, Accessible, Interoperable, and Reusable (FAIR). PMID:29568489

The analysis of vehicle cold start emissions has become an issue of utmost importance since the cold phase occurs mainly in urban context, where most of the population lives. In this sense, this research work analyzes and quantifies the impacts of cold start in urban context using naturalistic driving data. Furthermore, an assessment of the influence of ambient temperature on the percentage of time spent on cold start was also performed. Regarding the impacts of ambient temperature on cold start duration, a higher percentage of time spent on cold start was found for lower ambient temperatures (80% of the time for 0°C and ~50% for 29°C). Results showed that, during cold start, energy consumption is >110% higher than during hot conditions while emissions are up to 910% higher. Moreover, a higher increase on both energy consumption and emissions was found for gasoline vehicles than for diesel vehicles. When assessing the impacts on a city perspective, results revealed that the impacts of cold start increase for more local streets. The main finding of this study is to provide evidence that a higher increase on emissions occurs on more local streets, where most of the population lives. This kind of knowledge is of particular relevance to urban planners in order to perform an informed definition of public policies and regulations to be implemented in the future, to achieve a cleaner and healthier urban environment.

This investigation sought to determine the effects of dry-land sprint start training on short track speed skating (STSS) start performance. Nine highly trained short track athletes completed a control period of normal STSS training followed by a four-week training intervention. Before and after the control and intervention periods, athletes performed three electronically timed dry-land and on-ice 14.43 m maximal sprint start efforts. The intervention consisted of two sprint sessions per week consisting of nine electronically timed 14.43 m dry-land sprint starts in addition to normal STSS training. The control period resulted in no substantial change in on-ice start performance (Mean Δ: -0.01 s, 95% Confidence Limits (CL): -0.08 to 0.05 s; Effect Size (ES): -0.05; Trivial) however, a small change was observed in dry-land start performance (Mean Δ: -0.07 s, 95% CL: -0.13 to -0.02 s; ES: -0.49). Following brief specific dry-land sprint start training a small improvement was observed in both on-ice (Mean Δ: -0.07 s, 95% CL: -0.13 to -0.01 s; ES: -0.33) and dry-land (Mean Δ: -0.04 s, 95% CL: -0.09 to 0.00 s; ES: -0.29) start performance. This investigation suggests STSS start performance can be improved through a brief dry-land sprint start training program.

Cocco, A; Valentini, V; Balducci, M; Mantello, G

1996-01-01

START is an advanced radiation therapy information system (RTIS) which connects direct information technology present in the devices with indirect information technology for clinical, administrative, information management integrated with the hospital information system (HIS). The following objectives are pursued: to support decision making in treatment planning and functional and information integration with the rest of the hospital; to enhance organizational efficiency of a Radiation Therapy Department; to facilitate the statistical evaluation of clinical data and managerial performance assessment; to ensure the safety and confidentiality of used data. For its development a working method based on the involvement of all operators of the Radiation Therapy Department, was applied. Its introduction in the work activity was gradual, trying to reuse and integrate the existing information applications. The START information flow identifies four major phases: admission, visit of admission, planning, therapy. The system main functionalities available to the radiotherapist are: clinical history/medical report linking function; folder function; planning function; tracking function; electronic mail and banner function; statistical function; management function. Functions available to the radiotherapy technician are: the room daily list function; management function: to the nurse the following functions are available: patient directing function; management function. START is a departmental client (pc-windows)-server (unix) developed on an integrated database of all information of interest (clinical, organizational and administrative) coherent with the standard and with a modular architecture which can evolve with additional functionalities in subsequent times. For a more thorough evaluation of its impact on the daily activity of a radiation therapy facility, a prolonged clinical validation is in progress.

Case studies of memory-impaired individuals consistently show that reminiscing with SenseCam images enhances event recall. This exploratory study examined whether a similar benefit would occur for the consolidation of memories in memory-unimpaired people. We tested delayed recall for atypical actions observed on a lengthy walk. Participants used SenseCam, a diary, or no external memory aid while walking, followed by reminiscence with SenseCam images, diary entries, or no aid, either alone (self-reminiscence) or with the experimenter (social reminiscence). One week later, when tested without SenseCam images or diary entries, prior social reminiscence produced greater recall than self-reminiscence, but there were no differences between memory aid conditions for action free recall or action order recall. When methodological variables were controlled, there was no recall advantage for SenseCam reminiscence with memory-unimpaired participants. The case studies and present study differ in multiple ways, making direct comparisons problematic. SenseCam is a valuable aid to the memory impaired, but its mnemonic value for non-clinical populations remains to be determined.

Tips for starting your own nurse practitioner practice.

Science.gov (United States)

Calmelat, A

1993-04-01

The decision to open a nurse practitioner practice is often difficult to make. Success depends on the possession of specific resources, such as adequate skills, finances, emotional support and the desire to be one's own boss. These skills will be critical as the NP develops a business plan and a budget, and makes important decisions, such as the form the business will take: sole proprietorship, partnership or corporation. Using external resources such as attorneys and accountants is also useful, especially when tackling issues of licenses, taxes and insurance. Start-up costs can be kept to a minimum with creativity and used equipment. In-house laboratories and reference laboratories must conform to strict regulations. A practice without established patients will need to market services aggressively through a successful mix of product, price, place and promotion. Patients' acceptance of the NP office will be enhanced by smooth patient flow, adequate space and cleanliness.

Making effective links to decision-making: Key challenges for health impact assessment

International Nuclear Information System (INIS)

Elliott, Eva; Francis, Sarah

2005-01-01

This paper draws on an exploratory research study to examine the effectiveness of health impact assessments in Wales. Through the review of five case study health impact assessments the research identified a number of benefits of the process in terms of skills and knowledge development amongst participants. The indirect contributions to decision-making were also evident including the way in which health impact assessment provided useful insights into the local community's perspective and raised awareness about the wider determinants of health. The process was also useful in establishing a dialogue between different stakeholders, which indirectly assisted decision-making and implementation. The direct links between health impact assessment and decision-making were more difficult to trace and this paper puts forward a number of suggestions for making those links more transparent. Suggestions include integrating decision-makers and clarifying the intended links to decision-making at the start of the health impact assessment process. Mainstreaming health impact assessment so that it is triggered as a routine part of all decision-making would help ensure it stands the best chance of informing decisions

Self-Evaluation of PANDA-FBG Based Sensing System for Dynamic Distributed Strain and Temperature Measurement.

Science.gov (United States)

Zhu, Mengshi; Murayama, Hideaki; Wada, Daichi

2017-10-12

A novel method is introduced in this work for effectively evaluating the performance of the PANDA type polarization-maintaining fiber Bragg grating (PANDA-FBG) distributed dynamic strain and temperature sensing system. Conventionally, the errors during the measurement are unknown or evaluated by using other sensors such as strain gauge and thermocouples. This will make the sensing system complicated and decrease the efficiency since more than one kind of sensor is applied for the same measurand. In this study, we used the approximately constant ratio of primary errors in strain and temperature measurement and realized the self-evaluation of the sensing system, which can significantly enhance the applicability, as well as the reliability in strategy making.

VAiRoma: A Visual Analytics System for Making Sense of Places, Times, and Events in Roman History.

Science.gov (United States)

Cho, Isaac; Dou, Wewnen; Wang, Derek Xiaoyu; Sauda, Eric; Ribarsky, William

2016-01-01

Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we propose a visual analytics approach to construct a data driven view of Roman history based on a large collection of Wikipedia articles. Extracting and enabling the discovery of useful knowledge on events, places, times, and their connections from large amounts of textual data has always been a challenging task. To this aim, we introduce VAiRoma, a visual analytics system that couples state-of-the-art text analysis methods with an intuitive visual interface to help users make sense of events, places, times, and more importantly, the relationships between them. VAiRoma goes beyond textual content exploration, as it permits users to compare, make connections, and externalize the findings all within the visual interface. As a result, VAiRoma allows users to learn and create new knowledge regarding Roman history in an informed way. We evaluated VAiRoma with 16 participants through a user study, with the task being to learn about roman piazzas through finding relevant articles and new relationships. Our study results showed that the VAiRoma system enables the participants to find more relevant articles and connections compared to Web searches and literature search conducted in a roman library. Subjective feedback on VAiRoma was also very positive. In addition, we ran two case studies that demonstrate how VAiRoma can be used for deeper analysis, permitting the rapid discovery and analysis of a small number of key documents even when the original collection contains hundreds of thousands of documents.

Is 8:30 a.m. Still Too Early to Start School? A 10:00 a.m. School Start Time Improves Health and Performance of Students Aged 13–16

Directory of Open Access Journals (Sweden)

Paul Kelley

2017-12-01

Full Text Available While many studies have shown the benefits of later school starts, including better student attendance, higher test scores, and improved sleep duration, few have used starting times later than 9:00 a.m. Here we report on the implementation and impact of a 10 a.m. school start time for 13 to 16-year-old students. A 4-year observational study using a before-after-before (A-B-A design was carried out in an English state-funded high school. School start times were changed from 8:50 a.m. in study year 0, to 10 a.m. in years 1–2, and then back to 8:50 a.m. in year 3. Measures of student health (absence due to illness and academic performance (national examination results were used for all students. Implementing a 10 a.m. start saw a decrease in student illness after 2 years of over 50% (p < 0.0005 and effect size: Cohen's d = 1.07, and reverting to an 8:50 a.m. start reversed this improvement, leading to an increase of 30% in student illness (p < 0.0005 and Cohen's d = 0.47. The 10:00 a.m. start was associated with a 12% increase in the value-added number of students making good academic progress (in standard national examinations that was significant (<0.0005 and equivalent to 20% of the national benchmark. These results show that changing to a 10:00 a.m. high school start time can greatly reduce illness and improve academic performance. Implementing school start times later than 8:30 a.m., which may address the circadian delay in adolescents' sleep rhythms more effectively for evening chronotypes, appears to have few costs and substantial benefits.

School Starting Age and Crime

DEFF Research Database (Denmark)

Landersø, Rasmus; Nielsen, Helena Skyt; Simonsen, Marianne

This paper investigates the effects of school starting age on crime while relying on variation in school starting age induced by administrative rules; we exploit that Danish children typically start first grade in the calendar year they turn seven, which gives rise to a discontinuity in children......’s school starting age. Analyses are carried out using register-based Danish data. We find that higher age at school start lowers the propensity to commit crime, but that this reduction is caused by incapacitation while human capital accumulation is unaffected. Importantly, we also find that the individuals...

"I have a connection!": The situated sense-making of an elementary student about the role of water in modeled vs. experienced ecosystems

Science.gov (United States)

Roberts, Lisa Elisabeth N.

Current policy and research have led the field of science education towards a model of "science as practice." In the past decade, several research programs on model-based reasoning practices in education have articulated key dimensions of practice, including constructing and defending models, comparing models to empirical data, using representations to identify patterns in data and use those as inscriptions to buttress arguments. This study presents a detailed case of how the use of a physical microcosm and children's self-directed representations of an ecosystem constrained and afforded student sense-making in an urban elementary classroom. The case analyzed the experiences of a 10-year old fifth grade student, Jorge, and the variation in his expressed understanding of ecosystems as he interacted with academic tasks, along with models and representations, to design, observe and explain an ecological microcosm. The study used a conceptual framework that brings together theories of situated cognition and Doyle's work on academic task to explain how and why Jorge's perception and communication of dimensions of ecosystem structure, function, and behavior appear to "come in and out of focus," influenced by the affordances of the tools and resources available, the academic task as given by the teacher, and Jorge's own experiences and knowledge of phenomena related to ecosystems. Findings from this study suggest that elementary students' ability or inability to address particular ecological concepts in a given task relate less to gaps in their understanding and more to the structure of academic tasks and learning contexts. The process of a student interacting with curriculum follows a dynamic trajectory and leads to emergent outcomes. As a result of the complex interactions of task, tools, and his own interests and agency, Jorge's attunement to the role of water in ecosystems comes in and out of focus throughout the unit. The instructional constraint of needing to

Utility systems operation: Optimisation-based decision making

International Nuclear Information System (INIS)

Velasco-Garcia, Patricia; Varbanov, Petar Sabev; Arellano-Garcia, Harvey; Wozny, Guenter

2011-01-01

Utility systems provide heat and power to industrial sites. The importance of operating these systems in an optimal way has increased significantly due to the unstable and in the long term rising prices of fossil fuels as well as the need for reducing the greenhouse gas emissions. This paper presents an analysis of the problem for supporting operator decision making under conditions of variable steam demands from the production processes on an industrial site. An optimisation model has been developed, where besides for running the utility system, also the costs associated with starting-up the operating units have been modelled. The illustrative case study shows that accounting for the shut-downs and start-ups of utility operating units can bring significant cost savings. - Highlights: → Optimisation methodology for decision making on running utility systems. → Accounting for varying steam demands. → Optimal operating specifications when a demand change occurs. → Operating costs include start-up costs of boilers and other units. → Validated on a real-life case study. Up to 20% cost savings are possible.

Over the past 20 years, the international GOFC-GOLD Program and START, with core funding from the NASA LCLUC program and ESA have been developing regional networks of scientists and data users for scientific capacity building and sharing experience in the use and application of Earth Observation data. Regional networks connect scientists from countries with similar environmental and social issues and often with shared water and airsheds. Through periodic regional workshops, regional and national projects are showcased and national priorities and policy drivers are articulated. The workshops encourage both north-south and south-south exchange and collaboration. The workshops are multi-sponsored and each include a training component, targeting early career scientists and data users from the region. The workshops provide an opportunity for regional scientists to publish in peer-reviewed special editions focused on regional issues. Currently, the NASA LCLUC program funded "South and Southeast Asia Regional Initiative (SARI)" team is working closely with the USAID/NASA SERVIR program to implement some capacity building and training activities jointly in south/southeast Asian countries to achieve maximum benefit.

Remote-sensing image encryption in hybrid domains

Science.gov (United States)

Zhang, Xiaoqiang; Zhu, Guiliang; Ma, Shilong

2012-04-01

Remote-sensing technology plays an important role in military and industrial fields. Remote-sensing image is the main means of acquiring information from satellites, which always contain some confidential information. To securely transmit and store remote-sensing images, we propose a new image encryption algorithm in hybrid domains. This algorithm makes full use of the advantages of image encryption in both spatial domain and transform domain. First, the low-pass subband coefficients of image DWT (discrete wavelet transform) decomposition are sorted by a PWLCM system in transform domain. Second, the image after IDWT (inverse discrete wavelet transform) reconstruction is diffused with 2D (two-dimensional) Logistic map and XOR operation in spatial domain. The experiment results and algorithm analyses show that the new algorithm possesses a large key space and can resist brute-force, statistical and differential attacks. Meanwhile, the proposed algorithm has the desirable encryption efficiency to satisfy requirements in practice.

2003-11-01

Full Text Available Decision-making is defined as a selection of a certain actionamong several alternatives. It is the essence of planning, asin the managerial sense there is no plan until a decision of engagementof resources, reputation and direction of activities ismade. Decision-making is, in fact, only a step in planning, evenwhen it is performed quickly and without special consideration.It is what we all experience every day. It is one of the most fascinatingbiological activities and the subject of frightening implicationsfor the whole human race. Since various techniques improvethe system and the quality of managerial decision-making,they are classified into three assumptions: risk analysis, decision-making trees, and the theory of revealed preference. Allof these are based on the interaction of a certain number of importantvariables out of which many contain the elements ofuncertainty, but maybe also high level of probability.

Planning and decision making for aerial robots

CERN Document Server

Bestaoui Sebbane, Yasmina

2014-01-01

This book provides an introduction to the emerging field of planning and decision making for aerial robots. An aerial robot is the ultimate form of Unmanned Aerial Vehicle, an aircraft endowed with built-in intelligence, requiring no direct human control and able to perform a specific task. It must be able to fly within a partially structured environment, to react and adapt to changing environmental conditions and to accommodate for the uncertainty that exists in the physical world. An aerial robot can be termed as a physical agent that exists and flies in the real 3D world, can sense its environment and act on it to achieve specific goals. So throughout this book, an aerial robot will also be termed as an agent.   Fundamental problems in aerial robotics include the tasks of spatial motion, spatial sensing and spatial reasoning. Reasoning in complex environments represents a difficult problem. The issues specific to spatial reasoning are planning and decision making. Planning deals with the trajectory algori...

Mapping quorum sensing onto neural networks to understand collective decision making in heterogeneous microbial communities

Science.gov (United States)

Yusufaly, Tahir I.; Boedicker, James Q.

2017-08-01

Microbial communities frequently communicate via quorum sensing (QS), where cells produce, secrete, and respond to a threshold level of an autoinducer (AI) molecule, thereby modulating gene expression. However, the biology of QS remains incompletely understood in heterogeneous communities, where variant bacterial strains possess distinct QS systems that produce chemically unique AIs. AI molecules bind to ‘cognate’ receptors, but also to ‘non-cognate’ receptors found in other strains, resulting in inter-strain crosstalk. Understanding these interactions is a prerequisite for deciphering the consequences of crosstalk in real ecosystems, where multiple AIs are regularly present in the same environment. As a step towards this goal, we map crosstalk in a heterogeneous community of variant QS strains onto an artificial neural network model. This formulation allows us to systematically analyze how crosstalk regulates the community’s capacity for flexible decision making, as quantified by the Boltzmann entropy of all QS gene expression states of the system. In a mean-field limit of complete cross-inhibition between variant strains, the model is exactly solvable, allowing for an analytical formula for the number of variants that maximize capacity as a function of signal kinetics and activation parameters. An analysis of previous experimental results on the Staphylococcus aureus two-component Agr system indicates that the observed combination of variant numbers, gene expression rates and threshold concentrations lies near this critical regime of parameter space where capacity peaks. The results are suggestive of a potential evolutionary driving force for diversification in certain QS systems.

Ignorance is bliss. How parents of preschool children make sense of front-of-package visuals and claims on food.

Science.gov (United States)

Abrams, Katie M; Evans, Caitlin; Duff, Brittany R L

2015-04-01

With growing scrutiny over how the food industry advertises products aimed toward children and fewer consumers using nutrition facts panels and ingredient lists, the fronts of food packages have become an increasingly important marketing tool to understand. Front-of-package (FOP) visual and verbal claims play a critical role in capturing consumers' attention and helping them choose foods that fit their goals. Due to only possessing emergent literacy skills, preschool children are attuned to FOP visuals while parents are able to use the visuals in combination with verbal claims to make food choices for their children. The purpose of this focus group study was to explore how parents of preschool children make sense of FOP visual and verbal claims on packaged food products that are intended for their children. Thematic analysis revealed that parents associated aspects that most appeal to their preschool children - the characters and other playful visuals - with higher sugar content and artificial ingredients. However, parents were also easily led to believe the product was healthier based on visuals of fruit, more realistic pictures, health claims, cross-branding with healthier foods, and visuals suggesting the product is more natural. While parents recognized that the health claims and some visuals may not truly mean the food is healthier, they agreed that they rarely think beyond their initial impression. The food industry needs better regulatory guidance on how to communicate flavors and ingredients on package fronts in a way that helps consumers - particularly parents wanting to encourage healthy eating habits for their young children - better match their nutrition goals.

Full Text Available Surface acoustic wave (SAW resonators represent some of the most prominent acoustic devices for chemical sensing applications. As their frequency ranges from several hundred MHz to GHz, therefore they can record remarkably diminutive frequency shifts resulting from exceptionally small mass loadings. Their miniaturized design, high thermal stability and possibility of wireless integration make these devices highly competitive. Owing to these special characteristics, they are widely accepted as smart transducers that can be combined with a variety of recognition layers based on host-guest interactions, metal oxide coatings, carbon nanotubes, graphene sheets, functional polymers and biological receptors. As a result of this, there is a broad spectrum of SAW sensors, i.e., having sensing applications ranging from small gas molecules to large bio-analytes or even whole cell structures. This review shall cover from the fundamentals to modern design developments in SAW devices with respect to interfacial receptor coatings for exemplary sensor applications. The related problems and their possible solutions shall also be covered, with a focus on emerging trends and future opportunities for making SAW as established sensing technology.

Geological remote sensing signatures of terrestrial impact craters

International Nuclear Information System (INIS)

Garvin, J.B.; Schnetzler, C.; Grieve, R.A.F.

1988-01-01

Geological remote sensing techniques can be used to investigate structural, depositional, and shock metamorphic effects associated with hypervelocity impact structures, some of which may be linked to global Earth system catastrophies. Although detailed laboratory and field investigations are necessary to establish conclusive evidence of an impact origin for suspected crater landforms, the synoptic perspective provided by various remote sensing systems can often serve as a pathfinder to key deposits which can then be targetted for intensive field study. In addition, remote sensing imagery can be used as a tool in the search for impact and other catastrophic explosion landforms on the basis of localized disruption and anomaly patterns. In order to reconstruct original dimensions of large, complex impact features in isolated, inaccessible regions, remote sensing imagery can be used to make preliminary estimates in the absence of field geophysical surveys. The experienced gained from two decades of planetary remote sensing of impact craters on the terrestrial planets, as well as the techniques developed for recognizing stages of degradation and initial crater morphology, can now be applied to the problem of discovering and studying eroded impact landforms on Earth. Preliminary results of remote sensing analyses of a set of terrestrial impact features in various states of degradation, geologic settings, and for a broad range of diameters and hence energies of formation are summarized. The intention is to develop a database of remote sensing signatures for catastrophic impact landforms which can then be used in EOS-era global surveys as the basis for locating the possibly hundreds of missing impact structures

Energy-efficient sensing in wireless sensor networks using compressed sensing.

Science.gov (United States)

Razzaque, Mohammad Abdur; Dobson, Simon

2014-02-12

Sensing of the application environment is the main purpose of a wireless sensor network. Most existing energy management strategies and compression techniques assume that the sensing operation consumes significantly less energy than radio transmission and reception. This assumption does not hold in a number of practical applications. Sensing energy consumption in these applications may be comparable to, or even greater than, that of the radio. In this work, we support this claim by a quantitative analysis of the main operational energy costs of popular sensors, radios and sensor motes. In light of the importance of sensing level energy costs, especially for power hungry sensors, we consider compressed sensing and distributed compressed sensing as potential approaches to provide energy efficient sensing in wireless sensor networks. Numerical experiments investigating the effectiveness of compressed sensing and distributed compressed sensing using real datasets show their potential for efficient utilization of sensing and overall energy costs in wireless sensor networks. It is shown that, for some applications, compressed sensing and distributed compressed sensing can provide greater energy efficiency than transform coding and model-based adaptive sensing in wireless sensor networks.

Does future-oriented thinking predict adolescent decision making?

Science.gov (United States)

Eskritt, Michelle; Doucette, Jesslyn; Robitaille, Lori

2014-01-01

A number of theorists, as well as plain common sense, suggest that future-oriented thinking (FOT) should be involved in decision making; therefore, the development of FOT should be related to better quality decision making. FOT and quality of the decision making were measured in adolescents as well as adults in 2 different experiments. Though the results of the first experiment revealed an increase in quality of decision making across adolescence into adulthood, there was no relationship between FOT and decision making. In the second experiment, FOT predicted performance on a more deliberative decision-making task independent of age, but not performance on the Iowa Gambling Task (IGT). Performance on the IGT was instead related to emotion regulation. The study's findings suggest that FOT can be related to reflective decision making but not necessarily decision making that is more intuitive.

Visual working memory and number sense: Testing the double deficit hypothesis in mathematics.

Toll, Sylke W M; Kroesbergen, Evelyn H; Van Luit, Johannes E H

2016-09-01

Evidence exists that there are two main underlying cognitive factors in mathematical difficulties: working memory and number sense. It is suggested that real math difficulties appear when both working memory and number sense are weak, here referred to as the double deficit (DD) hypothesis. The aim of this study was to test the DD hypothesis within a longitudinal time span of 2 years. A total of 670 children participated. The mean age was 4.96 years at the start of the study and 7.02 years at the end of the study. At the end of the first year of kindergarten, both visual-spatial working memory and number sense were measured by two different tasks. At the end of first grade, mathematical performance was measured with two tasks, one for math facts and one for math problems. Multiple regressions revealed that both visual working memory and symbolic number sense are predictors of mathematical performance in first grade. Symbolic number sense appears to be the strongest predictor for both math areas (math facts and math problems). Non-symbolic number sense only predicts performance in math problems. Multivariate analyses of variance showed that a combination of visual working memory and number sense deficits (NSDs) leads to the lowest performance on mathematics. Our DD hypothesis was confirmed. Both visual working memory and symbolic number sense in kindergarten are related to mathematical performance 2 years later, and a combination of visual working memory and NSDs leads to low performance in mathematical performance. © 2016 The British Psychological Society.

Social class, sense of control, and social explanation.

Science.gov (United States)

Kraus, Michael W; Piff, Paul K; Keltner, Dacher

2009-12-01

Lower social class is associated with diminished resources and perceived subordinate rank. On the basis of this analysis, the authors predicted that social class would be closely associated with a reduced sense of personal control and that this association would explain why lower class individuals favor contextual over dispositional explanations of social events. Across 4 studies, lower social class individuals, as measured by subjective socioeconomic status (SES), endorsed contextual explanations of economic trends, broad social outcomes, and emotion. Across studies, the sense of control mediated the relation between subjective SES and contextual explanations, and this association was independent of objective SES, ethnicity, political ideology, and self-serving biases. Finally, experimentally inducing a higher sense of control attenuated the tendency for lower subjective SES individuals to make more contextual explanations (Study 4). Implications for future research on social class as well as theoretical distinctions between objective SES and subjective SES are discussed.

This level sets the stage for the design philosophy called “Triadic Game Design” (TGD). This design philosophy can be summarized with the following sentence: it takes two to tango, but it takes three to design a meaningful game or a game with a purpose. Before the philosophy is further explained, this level will first delve into what is meant by a meaningful game or a game with a purpose. Many terms and definitions have seen the light and in this book I will specifically orient at digital games that aim to have an effect beyond the context of the game itself. Subsequently, a historical overview is given of the usage of games with a serious purpose which starts from the moment we human beings started to walk on our feet till our contemporary society. It turns out that we have been using games for all kinds of non-entertainment purposes for already quite a long time. With this introductory material in the back of our minds, I will explain the concept of TGD by means of a puzzle. After that, the protagonist of this book, the game Levee Patroller, is introduced. Based on the development of this game, the idea of TGD, which stresses to balance three different worlds, the worlds of Reality, Meaning, and Play, came into being. Interested?

Full Text Available With the advent of the Internet of Things (IoT concept and its integration with the smart city sensing, smart connected health systems have appeared as integral components of the smart city services. Hard sensing-based data acquisition through wearables or invasive probes, coupled with soft sensing-based acquisition such as crowd-sensing results in hidden patterns in the aggregated sensor data. Recent research aims to address this challenge through many hidden perceptron layers in the conventional artificial neural networks, namely by deep learning. In this article, we review deep learning techniques that can be applied to sensed data to improve prediction and decision making in smart health services. Furthermore, we present a comparison and taxonomy of these methodologies based on types of sensors and sensed data. We further provide thorough discussions on the open issues and research challenges in each category.

To improve interventional training we propose a staged rational approach for decision making and skill acquisition. Education and training for endovascular interventions should start to develop the learners' decision-making skills by learning from explicit representations of master interventionist's tacit decision-making knowledge through implementation of the notions of generic interventional modules, interventional strategic and tactical designs. We hope that these suggestions will encourage action, stimulate dialogue and advance the precision of our learning, procedures, practice and patient care.

The diagnosis of inherited neuropathies can be challenging in several ways. First, a hereditary neuropathy must be suspected. Although some family histories are clear with multiple members affected, other families require directed inquiry. Second, even when a hereditary neuropathy is clear, it can be difficult to make a genetic characterization. The field of genotyping is expanding so rapidly, it is difficult to know what tests to order. The authors share their guidelines for the diagnosis of inherited neuropathies. © Thieme Medical Publishers.

Shatalov, Max; Bilenko, Yuri; Yang, Jinwei; Gaska, Remis

2009-09-01

III-Nitride based deep ultraviolet (DUV) light emitting diodes (LEDs) rapidly penetrate into sensing market owing to several advantages over traditional UV sources (i.e. mercury, xenon and deuterium lamps). Small size, a wide choice of peak emission wavelengths, lower power consumption and reduced cost offer flexibility to system integrators. Short emission wavelength offer advantages for gas detection and optical sensing systems based on UV induced fluorescence. Large modulation bandwidth for these devices makes them attractive for frequency-domain spectroscopy. We will review present status of DUV LED technology and discuss recent advances in short wavelength emitters and high power LED lamps.

2010-01-01

We present typical device characteristics of novel DFB laser diodes which are employed in various sensing applications including high resolution photoacoustic spectroscopy. The laser diodes discussed are based on a genuine fabrication technology which allows for the production of ultra stable devices within a broad spectral range from 760 nm up to 3000 nm wavelength. The devices exhibit narrow linewidths down to <1 MHz which makes them ideally suited for all photoacoustic sensing applications where a high spectral purity is required. As an example we will focus on a typical medical application where these diodes are used for breath analysis using photoacoustic spectroscopy.

This invention is a force and deflection sensor a flexible shell formed with an elastomer having passageways formed by apertures in the shell, with an optical fiber having one or more Bragg gratings positioned in the passageways for the measurement of force and deflection.

Mesoporous Silicate Materials in Sensing

Directory of Open Access Journals (Sweden)

Paul T. Charles

2008-08-01

Full Text Available Mesoporous silicas, especially those exhibiting ordered pore systems and uniform pore diameters, have shown great potential for sensing applications in recent years. Morphological control grants them versatility in the method of deployment whether as bulk powders, monoliths, thin films, or embedded in coatings. High surface areas and pore sizes greater than 2 nm make them effective as adsorbent coatings for humidity sensors. The pore networks also provide the potential for immobilization of enzymes within the materials. Functionalization of materials by silane grafting or through cocondensation of silicate precursors can be used to provide mesoporous materials with a variety of fluorescent probes as well as surface properties that aid in selective detection of specific analytes. This review will illustrate how mesoporous silicas have been applied to sensing changes in relative humidity, changes in pH, metal cations, toxic industrial compounds, volatile organic compounds, small molecules and ions, nitroenergetic compounds, and biologically relevant molecules.

Full Text Available Start-up relationships with business angel and/or venture capital are similar to a marriage – but with a divorce in mind. The latter necessitates a proper prenuptial agreement signing at the very beginning of the relations. In case of business angel and/or venture capital we are speaking about Term sheet, determining pricing, powers and duties of the board, as well as information, participation and protective rights for the partners. Standard Term sheet consists of three buckets of provisions, defining: (i terms impacting start-up valuation and economic division of profits and proceeds upon a liquidity event, (ii terms impacting control over decision making and (iii investor protection terms. This article focuses on financial and economic aspects of funding agreement, exposing some tricky parts of the Term sheet, threatening to transform potential win-win deals into rupture of relations, crash of the company or even legal battles. The results of the analysis are used to substantiate growing in popular appeal thesis that raising too much money can be detrimental for a startup.

2011-12-07

Ionic Liquids are salts that are liquid at (or just above) room temperature. They possess several advantageous properties (e.g. high intrinsic conductivity, wide electrochemical windows, low volatility, high thermal stability and good solvating ability), which make them ideal as non-volatile electrolytes in electrochemical sensors. This mini-review article describes the recent uses of ionic liquids in electrochemical sensing applications (covering the last 3 years) in the context of voltammetric sensing at solid/liquid, liquid/liquid interfaces and carbon paste electrodes, as well as their use in gas sensing, ion-selective electrodes, and for detecting biological molecules, explosives and chemical warfare agents. A comment on the future direction and challenges in this field is also presented.

A Review of Ocean/Sea Subsurface Water Temperature Studies from Remote Sensing and Non-Remote Sensing Methods

Directory of Open Access Journals (Sweden)

Elahe Akbari

2017-12-01

Full Text Available Oceans/Seas are important components of Earth that are affected by global warming and climate change. Recent studies have indicated that the deeper oceans are responsible for climate variability by changing the Earth’s ecosystem; therefore, assessing them has become more important. Remote sensing can provide sea surface data at high spatial/temporal resolution and with large spatial coverage, which allows for remarkable discoveries in the ocean sciences. The deep layers of the ocean/sea, however, cannot be directly detected by satellite remote sensors. Therefore, researchers have examined the relationships between salinity, height, and temperature of the oceans/Seas to estimate their subsurface water temperature using dynamical models and model-based data assimilation (numerical based and statistical approaches, which simulate these parameters by employing remotely sensed data and in situ measurements. Due to the requirements of comprehensive perception and the importance of global warming in decision making and scientific studies, this review provides comprehensive information on the methods that are used to estimate ocean/sea subsurface water temperature from remotely and non-remotely sensed data. To clarify the subsurface processes, the challenges, limitations, and perspectives of the existing methods are also investigated.

Theology in the flesh – a model for theological anthropology as embodied sensing

Directory of Open Access Journals (Sweden)

Jacob Meiring

2015-06-01

Full Text Available The author proposes a model for theological anthropology as embodied sensing that is based on an interdisciplinary exploration of the corporeal turn from a southern African perspective. The work of James B. Nelson is acknowledged, stating that body theology starts with the concrete, the bodily expressions of life and not with doctrines about God and humanity. The theological anthropology of David H. Kelsey is evaluated as a theological anthropology with a sentiment of the flesh. Based on clearings in the work of David Kelsey and an interdisciplinary research, the author proposes a model for theological anthropology as embodied sensing which functions within the intricate and complex connection of the living body, language and experiencing in a concrete lifeworld with an openness to the ‘more than’. The author considers the use of bodymapping within narrative therapy as a way in which to uncover the intimate and intricate connection between the living body, experience and language, and implementing insights from theological anthropology as embodied sensing.

What is a picture worth? A history of remote sensing

Remote sensing is the use of electromagnetic energy to measure the physical properties of distant objects. It includes photography and geophysical surveying as well as newer techniques that use other parts of the electromagnetic spectrum. The history of remote sensing begins with photography. The origin of other types of remote sensing can be traced to World War II, with the development of radar, sonar, and thermal infrared detection systems. Since the 1960s, sensors have been designed to operate in virtually all of the electromagnetic spectrum. Today a wide variety of remote sensing instruments are available for use in hydrological studies; satellite data, such as Skylab photographs and Landsat images are particularly suitable for regional problems and studies. Planned future satellites will provide a ground resolution of 10–80 m. Remote sensing is currently used for hydrological applications in most countries of the world. The range of applications includes groundwater exploration determination of physical water quality, snowfield mapping, flood-inundation delineation, and making inventories of irrigated land. The use of remote sensing commonly results in considerable hydrological information at minimal cost. This information can be used to speed-up the development of water resources, to improve management practices, and to monitor environmental problems.

Study on Method of Geohazard Change Detection Based on Integrating Remote Sensing and GIS

International Nuclear Information System (INIS)

Zhao, Zhenzhen; Yan, Qin; Liu, Zhengjun; Luo, Chengfeng

2014-01-01

Following a comprehensive literature review, this paper looks at analysis of geohazard using remote sensing information. This paper compares the basic types and methods of change detection, explores the basic principle of common methods and makes an respective analysis of the characteristics and shortcomings of the commonly used methods in the application of geohazard. Using the earthquake in JieGu as a case study, this paper proposes a geohazard change detection method integrating RS and GIS. When detecting the pre-earthquake and post-earthquake remote sensing images at different phases, it is crucial to set an appropriate threshold. The method adopts a self-adapting determination algorithm for threshold. We select a training region which is obtained after pixel information comparison and set a threshold value. The threshold value separates the changed pixel maximum. Then we apply the threshold value to the entire image, which could also make change detection accuracy maximum. Finally, we output the result to the GIS system to make change analysis. The experimental results show that this method of geohazard change detection based on integrating remote sensing and GIS information has higher accuracy with obvious advantages compared with the traditional methods

Investigation of the internal behavior in segmented PEMFCs of different flow fields during cold start process

International Nuclear Information System (INIS)

2017-01-01

In this study, we have researched the internal behavior in segmented proton exchange membrane fuel cells (PEMFCs) with three different flow fields during cold start process. The change of internal current density and temperature in fuel cells with different flow fields could be obviously shown by the printed circuit board (PCB) technology, and the study shows that the flow field is significant for enhancing the cold start ability and durability. Single serpentine flow field has the best cold start performance, while triple channel serpentine flow field has the best uniformity. It is found that without a robust temperature rising tendency, the cell temperature reaching 0 °C does not definitely mean a successful cold start because the cell temperature might drop down 0 °C again. Polarization curves show that there is almost no performance degradation after successful cold start, but the cell degrades quickly after the failed cold start at −7 °C and −10 °C. Based on these characteristics, we optimized the rapid cold start strategy by using electric heating and make it possible to start up the PEMFC at temperatures down to −20 °C within about 11 min. - Highlights: • Segmented fuel cell were used to record the internal current density and temperature distributions during the cold start. • The effects of flow fields on the PEMFC cold start capacity were evaluated. • The effect of cold start on the performance of fuel cell was evaluated. • An optimized strategy was adopted to improve the cold start capacity.

The aim of this study was to demonstrate that cells which are expressing a particular mRNA transcript do preferentially and specifically retain the antisense probe targeting that mRNA. Using a mouse plasmacytoma cell line (MOPC315) which produces high levels of IgA heavy chain mRNA, a control mouse pre B cell line (7OZ/3B), a human mammary cell line (MCF7) which expresses the erbB2 or neu oncogene, MOPC315 cells as neu-negative controls, and antisense DNA oligonucleotides complementary to the 5' region of the mRNAs and the sense sequence, we have shown that there is a preferential, specific retention of the IgA and neu antisense sequence in MOPC315 and MCF7 cells, respectively. We have further demonstrated that this retention is time and concentration dependent with a maximum at 24 h. We conclude that cancer cells which express a particular oncogene are suitable targets for radiolabeled antisense deoxyoligonucleotides directed toward the oncogene transcript. (orig.)

Pre-start timing information is used to set final linear speed in a C-start manoeuvre.

In their unique hunting behaviour, archerfish use a complex motor decision to secure their prey: based solely on how dislodged prey initially falls, they select an adapted C-start manoeuvre that turns the fish right towards the point on the water surface where their prey will later land. Furthermore, they take off at a speed that is set so as to arrive in time. We show here that the C-start manoeuvre and not subsequent tail beating is necessary and sufficient for setting this adaptive level of speed. Furthermore, the C-start pattern is adjusted to independently determine both the turning angle and the take-off speed. The selection of both aspects requires no a priori information and is done based on information sampled from the onset of target motion until the C-start is launched. Fin strokes can occur right after the C-start manoeuvre but are not required to fine-tune take-off speed, but rather to maintain it. By probing the way in which the fish set their take-off speed in a wide range of conditions in which distance from the later catching point and time until impact varied widely and unpredictably, we found that the C-start manoeuvre is programmed based on pre-C-start estimates of distance and time until impact. Our study hence provides the first evidence for a C-start that is fine-tuned to produce an adaptive speed level. © 2014. Published by The Company of Biologists Ltd.

PERFORMANCE OF OPPORTUNISTIC SPECTRUM ACCESS WITH SENSING ERROR IN COGNITIVE RADIO AD HOC NETWORKS

Directory of Open Access Journals (Sweden)

N. ARMI

2012-04-01

Full Text Available Sensing in opportunistic spectrum access (OSA has a responsibility to detect the available channel by performing binary hypothesis as busy or idle states. If channel is busy, secondary user (SU cannot access and refrain from data transmission. SU is allowed to access when primary user (PU does not use it (idle states. However, channel is sensed on imperfect communication link. Fading, noise and any obstacles existed can cause sensing errors in PU signal detection. False alarm detects idle states as a busy channel while miss-identification detects busy states as an idle channel. False detection makes SU refrain from transmission and reduces number of bits transmitted. On the other hand, miss-identification causes SU collide to PU transmission. This paper study the performance of OSA based on the greedy approach with sensing errors by the restriction of maximum collision probability allowed (collision threshold by PU network. The throughput of SU and spectrum capacity metric is used to evaluate OSA performance and make comparisons to those ones without sensing error as function of number of slot based on the greedy approach. The relations between throughput and signal to noise ratio (SNR with different collision probability as well as false detection with different SNR are presented. According to the obtained results show that CR users can gain the reward from the previous slot for both of with and without sensing errors. It is indicated by the throughput improvement as slot number increases. However, sensing on imperfect channel with sensing errors can degrade the throughput performance. Subsequently, the throughput of SU and spectrum capacity improves by increasing maximum collision probability allowed by PU network as well. Due to frequent collision with PU, the throughput of SU and spectrum capacity decreases at certain value of collision threshold. Computer simulation is used to evaluate and validate these works.

Full Text Available The effect of globalization and the increasing demands on the job market have induced many countries in the world to introduce reforms aimed at streamlining their higher education curricula. The demand for a more flexible workforce with high skills (competencies in problem solving, team work and project management has been on the rise in recent years and the incorporation of competency-based curriculum has emerged as a necessity in the higher education sector. However, in spite of the growing popularity for the need to prepare graduates for the workplace, the actual academic culture and formative processes are yet to be tailored to address these new exigencies. The aim of this paper is to analyze in what manner competence and competence-based learning are being currently implemented in the Advanced School of Translators and Interpreters (ASTI of the University of Buea in Cameroon. Competency dashboard indicators from best practice frameworks are used to assess stakeholders’ sense-making as levers for quality assessment in translation learning. An opinion survey of 60 trainee translators and 12 instructors helped to identify factors, instructional and otherwise which promote or inhibit the success of competence-based education. The study posits that systemic and environmental issues, as well as organizational, teaching and learning, assessment, and quality assurance issues are germane to the effective implementation of generic and specific competencies. The ensuing proposals advocate for a responsive translator training and education that is more personalized and adaptive to address higher education’s challenges of access, quality, and affordability for a diverse set of students.

Precision force sensing with optically-levitated nanospheres

Geraci, Andrew

2017-04-01

In high vacuum, optically-trapped dielectric nanospheres achieve excellent decoupling from their environment and experience minimal friction, making them ideal for precision force sensing. We have shown that 300 nm silica spheres can be used for calibrated zeptonewton force measurements in a standing-wave optical trap. In this optical potential, the known spacing of the standing wave anti-nodes can serve as an independent calibration tool for the displacement spectrum of the trapped particle. I will describe our progress towards using these sensors for tests of the Newtonian gravitational inverse square law at micron length scales. Optically levitated dielectric objects also show promise for a variety of other precision sensing applications, including searches for gravitational waves and other experiments in quantum optomechanics.

Affordable dual-sensing proximity sensor for touchless interactive systems

KAUST Repository

Nassar, Joanna M.

2016-09-13

We report an ultra-low cost flexible proximity sensor using only off-the-shelf recyclable materials such as aluminum foil, napkin and double-sided tape. Unlike previous reports, our device structure exhibits two sensing capabilities in one platform, with outstanding long detection range of 20 cm and pressure sensitivity of 0.05 kPa. This is the first ever demonstration of a low-cost, accessible, and batch manufacturing process for pressure and proximity sensing on a singular platform. The mechanical flexibility of the sensor makes it possible to mount on various irregular platforms, which is vital in many areas, such as robotics, machine automation, vehicular technology and inspection tools.

Making Sense of Biodiversity: The Affordances of Systems Ecology.

Andersson, Erik; McPhearson, Timon

We see two related, but not well-linked fields that together could help us better understand biodiversity and how it, over time, provides benefits to people. The affordances approach in environmental psychology offers a way to understand our perceptual appraisal of landscapes and biodiversity and, to some extent, intentional choice or behavior, i.e., a way of relating the individual to the system s/he/it lives in. In the field of ecology, organism-specific functional traits are similarly understood as the physiological and behavioral characteristics of an organism that informs the way it interacts with its surroundings. Here, we review the often overlooked role of traits in the provisioning of ecosystem services as a potential bridge between affordance theory and applied systems ecology. We propose that many traits can be understood as the basis for the affordances offered by biodiversity, and that they offer a more fruitful way to discuss human-biodiversity relations than do the taxonomic information most often used. Moreover, as emerging transdisciplinary studies indicate, connecting affordances to functional traits allows us to ask questions about the temporal and two-way nature of affordances and perhaps most importantly, can serve as a starting point for more fully bridging the fields of ecology and environmental psychology with respect to how we understand human-biodiversity relationships.

Distributed Long-Gauge Optical Fiber Sensors Based Self-Sensing FRP Bar for Concrete Structure.

2016-02-25

Brillouin scattering-based distributed optical fiber (OF) sensing technique presents advantages for concrete structure monitoring. However, the existence of spatial resolution greatly decreases strain measurement accuracy especially around cracks. Meanwhile, the brittle feature of OF also hinders its further application. In this paper, the distributed OF sensor was firstly proposed as long-gauge sensor to improve strain measurement accuracy. Then, a new type of self-sensing fiber reinforced polymer (FRP) bar was developed by embedding the packaged long-gauge OF sensors into FRP bar, followed by experimental studies on strain sensing, temperature sensing and basic mechanical properties. The results confirmed the superior strain sensing properties, namely satisfied accuracy, repeatability and linearity, as well as excellent mechanical performance. At the same time, the temperature sensing property was not influenced by the long-gauge package, making temperature compensation easy. Furthermore, the bonding performance between self-sensing FRP bar and concrete was investigated to study its influence on the sensing. Lastly, the sensing performance was further verified with static experiments of concrete beam reinforced with the proposed self-sensing FRP bar. Therefore, the self-sensing FRP bar has potential applications for long-term structural health monitoring (SHM) as embedded sensors as well as reinforcing materials for concrete structures.

Making sense of biologists' teaching: Two case studies of beliefs and discourse practices

Science.gov (United States)

Fifield, Steven James

1999-09-01

Undergraduate science courses are often criticized for their overemphasis of content coverage, neglect of inquiry approaches, and misrepresentation of the nature of science. Because conventional courses are influential models for future science teachers, they are often viewed as impediments to K--12 science education reform. To effectively modify how professors teach, we first need to better understand their beliefs and practices as teachers. This is an interpretive study of how two biology professors (Jim and Sue) make sense of their classroom practices in an introductory undergraduate course. Interviews are used to analyze their beliefs about teaching, learning, and science. Discourse analysis of lectures on classical genetics is used to examine their classroom practices as situated constructions of scientific knowledge. The two professors' held distinct beliefs about teaching and learning that were intricately interwoven with their beliefs about science. Jim's beliefs were largely consistent with conventional approaches to introductory science courses. He thought that introductory courses support the development of knowledge and skills that students need before they can engage in scientific inquiry. Sarah was critical of these conventional approaches. She valued courses that foster active learning and focus on applications of biology that are relevant to students' lives. But she could not enact many of her beliefs due to situational constraints associated with the course. Instead she viewed her efforts to help students succeed in a conventional course as a way to resist her colleagues' expectations that most students cannot do well in science. Discourse analysis of the professors' lectures revealed that they both relied on narratives to represent concepts in classical genetics. These narratives of concepts were distinct from other narrative forms in technical and popular presentations of biology. The relationship among these professors' beliefs and classroom

‘Killing Me Softly With His/Her Song’: How Leaders Dismantle Followers’ Sense of Work Meaningfulness

Directory of Open Access Journals (Sweden)

Petra Kipfelsberger

2018-05-01

Full Text Available Leaders influence followers’ meaning and play a key role in shaping their employees’ experience of work meaningfulness. While the dominant perspective in theory and in empirical work focuses on the positive influence of leaders on followers’ work meaningfulness, our conceptual model explores conditions in which leaders may harm followers’ sense of meaning. We introduce six types of conditions: leaders’ personality traits, leaders’ behaviors, the relationship between leader and follower, followers’ attributions, followers’ characteristics, and job design under which leaders’ meaning making efforts might harm or ‘kill’ followers’ sense of work meaningfulness. Accordingly, we explore how these conditions may interact with leaders’ meaning making efforts to lower levels of followers’ sense of meaning, and in turn, lead to negative personal outcomes (cynicism, lower well-being, and disengagement, as well as negative organizational outcomes (corrosive organizational energy, higher turnover rates, and lower organizational productivity. By doing so, our research extends the current literature, enabling a more comprehensive understanding of leaders’ influence on followers’ work meaningfulness, while considering the dark side of meaning making.

Going beyond the Control of Quorum-Sensing to Combat Biofilm Infections

Directory of Open Access Journals (Sweden)

Wolf-Rainer Abraham

2016-01-01

Full Text Available Most bacteria attach to surfaces where they form a biofilm, cells embedded in a complex matrix of polymers. Cells in biofilms are much better protected against noxious agents than free-living cells. As a consequence it is very difficult to control pathogens with antibiotics in biofilm infections and novel targets are urgently needed. One approach aims at the communication between cells to form and to maintain a biofilm, a process called quorum-sensing. Water soluble small-sized molecules mediate this process and a number of antagonists of these compounds have been found. In this review natural compounds and synthetic drugs which do not interfere with the classical quorum-sensing compounds are discussed. For some of these compounds the targets are still not known, but others interfere with the formation of exopolysaccharides, virulence factors, or cell wall synthesis or they start an internal program of biofilm dispersal. Some of their targets are more conserved among pathogens than the receptors for quorum sensing autoinducers mediating quorum-sensing, enabling a broader application of the drug. The broad spectrum of mechanisms, the diversity of bioactive compounds, their activity against several targets, and the conservation of some targets among bacterial pathogens are promising aspects for several clinical applications of this type of biofilm-controlling compound in the future.

Web tools concerning performance analysis and planning support for solar energy plants starting from remotely sensed optical images

We present innovative web tools, developed also in the frame of the FP7 ENDORSE (ENergy DOwnstReam SErvices) project, for the performance analysis and the support in planning of solar energy plants (PV, CSP, CPV). These services are based on the combination between the detailed physical model of each part of the plants and the near real-time satellite remote sensing of incident solar irradiance. Starting from the solar Global Horizontal Irradiance (GHI) data provided by the Monitoring Atmospheric Composition and Climate (GMES-MACC) Core Service and based on the elaboration of Meteosat Second Generation (MSG) satellite optical imagery, the Global Tilted Irradiance (GTI) or the Beam Normal Irradiance (BNI) incident on plant's solar PV panels (or solar receivers for CSP or CPV) is calculated. Combining these parameters with the model of the solar power plant, using also air temperature values, we can assess in near-real-time the daily evolution of the alternate current (AC) power produced by the plant. We are therefore able to compare this satellite-based AC power yield with the actually measured one and, consequently, to readily detect any possible malfunctions and to evaluate the performances of the plant (so-called “Controller” service). Besides, the same method can be applied to satellite-based averaged environmental data (solar irradiance and air temperature) in order to provide a Return on Investment analysis in support to the planning of new solar energy plants (so-called “Planner” service). This method has been successfully applied to three test solar plants (in North, Centre and South Italy respectively) and it has been validated by comparing satellite-based and in-situ measured hourly AC power data for several months in 2013 and 2014. The results show a good accuracy: the overall Normalized Bias (NB) is − 0.41%, the overall Normalized Mean Absolute Error (NMAE) is 4.90%, the Normalized Root Mean Square Error (NRMSE) is 7.66% and the overall

Baumard et al. make a good case that a sense of fairness evolved and that showing this requires reciprocity games with choice of partner. However, they oversimplify both morality and the evolution of morality. Where fairness is involved in morality, other things are, too, and fairness is often not involved. In the evolution of morality, other things played a role. Plus, the motive for being fair originally was self-interest, not anything moral.

Marketing Remote Sensing Data for North Pacific Fisheries Development and Management

Fish poaching, drug trafficking, ocean dumping, and other illegal activities are important problems on the high seas and in national economic zones. The primary thrust of the EOCAP II project, "Marketing Remote Sensing Data for North Pacific Fisheries Development and Management", was to use space-based sensors to improve the effectiveness of marine monitoring, control, and surveillance (MCS). Our initial objectives were to concentrate on the development of MCS tools using Advanced Very High Resolution Radiometry (AVHRR) and Synthetic Aperture Radar (SAR) data. Although we have successfully completed development of an initial version of our SAR-based monitoring tool (OmniVision), project activity has resulted in a much broader application of space-based assets to marine applications. Based in part on work commenced within EOCAP II, a new company, Ocean and Coastal Environmental Sensing, Inc. (OCENS), has been launched and the development of several new software products outside of the MCS arena initiated. One of those products, SeaStation, is near completion with a Fall, 1995 release date. Equity investment in OCENS now totals $70,000-with an additional amount being sought in the first round of financing. One of the pre-eminent objectives of EOCAP II is to make contributions to the US economy and job growth through the expansion of commercial uses of remotely sensed data. OCENS and the software products it is introducing into marine and coastal zone markets responds to this primary object*e. EOCAP II funding leveraged the market and technical know-how of OCENS founders into smart products that benefit marine and coastal zone users. Although technical difficulties and geopolitical shifts damaged the commercial feasibility of initial project objectives, the flexibility of the EOCAP II program now permits long-term business success. This in no small part stems from the fact that the EOCAP program recognizes the realities of small and start-up businesses and does not

This paper presents an overview of the research activities undertaken by La Salle and the Ebro Observatory in the field of remote sensing. On 2003 we started a research project with two main objectives: implement a long-haul oblique ionospheric sounder and transmit the data from remote sensors located at the Spanish Antarctic station Juan Carlos I to Spain. The paper focuses on a study of feasibility of two possible physical layer candidates for the skywave link between both points. A DS-SS based solution and an OFDM based solution are considered to achieve a reliable low-power low-rate communication system between Antarctica and Spain.

Exposure and sense of threat have been associated with stress symptoms, yet these relationships have not been clarified during the peritraumatic period. We investigated the mediating role of sense of threat in the link between exposure to rocket warning sirens and stress symptoms during wartime, and the effect of severe mental illness (SMI) status and gender on this mediation. A 30-day twice-daily smartphone-based intensive assessment of exposure to sirens, sense of threat, and peritraumatic stress symptoms was performed during the 2014 Israel-Gaza conflict. Participants included 182 highly exposed individuals with or without SMI. Multilevel structural equation modeling analysis was performed, with SMI status and gender as confounders. Exposure affected the level of peritraumatic stress symptoms both directly, b = 1.07, p development during the peritraumatic timeframe. Intervention and prevention efforts should start early and focus on promoting a sense of safety, particularly with people with SMI.

Starting physiology: bioelectrogenesis.

Baptista, Vander

2015-12-01

From a Cartesian perspective of rational analysis, the electric potential difference across the cell membrane is one of the fundamental concepts for the study of physiology. Unfortunately, undergraduate students often struggle to understand the genesis of this energy gradient, which makes the teaching activity a hard task for the instructor. The topic of bioelectrogenesis encompasses multidisciplinary concepts, involves several mechanisms, and is a dynamic process, i.e., it never turns off during the lifetime of the cell. Therefore, to improve the transmission and acquisition of knowledge in this field, I present an alternative didactic model. The design of the model assumes that it is possible to build, in a series of sequential steps, an assembly of proteins within the membrane of an isolated cell in a simulated electrophysiology experiment. Initially, no proteins are inserted in the membrane and the cell is at a baseline energy state; the extracellular and intracellular fluids are at thermodynamic equilibrium. Students are guided through a sequence of four steps that add key membrane transport proteins to the model cell. The model is simple at the start and becomes progressively more complex, finally producing transmembrane chemical and electrical gradients. I believe that this didactic approach helps instructors with a more efficient tool for the teaching of the mechanisms of resting membrane potential while helping students avoid common difficulties that may be encountered when learning this topic.

1999-09-14

Apparatus and methods for characterizing free-space electromagnetic energy, and in particular, apparatus/method suitable for real-time two-dimensional far-infrared imaging applications are presented. The sensing technique is based on a non-linear coupling between a low-frequency electric field and a laser beam in an electro-optic crystal. In addition to a practical counter-propagating sensing technique, a co-linear approach is described which provides longer radiated field--optical beam interaction length, thereby making imaging applications practical.

The SENSE-Isomorphism Theoretical Image Voxel Estimation (SENSE-ITIVE) Model for Reconstruction and Observing Statistical Properties of Reconstruction Operators

Science.gov (United States)

Bruce, Iain P.; Karaman, M. Muge; Rowe, Daniel B.

2012-01-01

The acquisition of sub-sampled data from an array of receiver coils has become a common means of reducing data acquisition time in MRI. Of the various techniques used in parallel MRI, SENSitivity Encoding (SENSE) is one of the most common, making use of a complex-valued weighted least squares estimation to unfold the aliased images. It was recently shown in Bruce et al. [Magn. Reson. Imag. 29(2011):1267–1287] that when the SENSE model is represented in terms of a real-valued isomorphism, it assumes a skew-symmetric covariance between receiver coils, as well as an identity covariance structure between voxels. In this manuscript, we show that not only is the skew-symmetric coil covariance unlike that of real data, but the estimated covariance structure between voxels over a time series of experimental data is not an identity matrix. As such, a new model, entitled SENSE-ITIVE, is described with both revised coil and voxel covariance structures. Both the SENSE and SENSE-ITIVE models are represented in terms of real-valued isomorphisms, allowing for a statistical analysis of reconstructed voxel means, variances, and correlations resulting from the use of different coil and voxel covariance structures used in the reconstruction processes to be conducted. It is shown through both theoretical and experimental illustrations that the miss-specification of the coil and voxel covariance structures in the SENSE model results in a lower standard deviation in each voxel of the reconstructed images, and thus an artificial increase in SNR, compared to the standard deviation and SNR of the SENSE-ITIVE model where both the coil and voxel covariances are appropriately accounted for. It is also shown that there are differences in the correlations induced by the reconstruction operations of both models, and consequently there are differences in the correlations estimated throughout the course of reconstructed time series. These differences in correlations could result in meaningful

Forest biodiversity and its assessment by remote sensing

Innes, J.L.; Koch, B.

Several international conventions and agreements have stressed the importance of the assessment of forest biodiversity. However, the methods by which such assessments can be made remain unclear. Remote sensing represents an important tool for looking at ecosystem diversity and various structural aspects of individual ecosystems. It provides a means to make assessments across several different spatial scales, and is also critical for assessments of changes in ecosystem pattern over time. Many different forms of remote sensing are available. While lately the emphasis on laser scanner and synthetic aperture radar data has increased, most work to date has used photographs and digital optical imagery, primarily from airborne and spaceborne platforms. These provide the opportunity to assess different phenomena from the landscape to the stand scale. Remote sensing provides the most efficient tool available for determining landscape-scale elements of forest biodiversity, such as the relative proportion of matrix and patches and their physical arrangement. At intermediate scales, remote sensing provides an ideal tool for evaluating the presence of corridors and the nature of edges. At the stand scale, remote sensing technologies are likely to deliver an increasing amount of information about the structural attributes of forest stands, such as the nature of the canopy surface, the presence of layering within the canopy and presence of (very) coarse woody debris on the forest floor. Given the rate of development in the technology, even greater usage is likely in the future. (author)

Both bias and lack of knowledge influence organizational focus on first case of the day starts.

The economic costs of reducing first case delays are often high, because efforts need to be applied to multiple operating rooms (ORs) simultaneously. Nevertheless, delays in starting first cases of the day are a common topic in OR committee meetings. We added three scientific questions to a 24 question online, anonymous survey performed before the implementation of a new OR information system. The 57 respondents cared sufficiently about OR management at the United States teaching hospital to complete all questions. The survey revealed reasons why personnel may focus on the small reductions in nonoperative time achievable by reducing tardiness in first cases of the day. (A) Respondents lacked knowledge about principles in reducing over-utilized OR time to increase OR efficiency, based on their answering the relevant question correctly at a rate no different from guessing at random. Those results differed from prior findings of responses at a rate worse than random, resulting from a bias on the day of surgery of making decisions that increase clinical work per unit time. (B) Most respondents falsely believed that a 10 min delay at the start of the day causes subsequent cases to start at least 10 min late (P less time than scheduled (P = 0.008 versus chance). No one who demonstrated knowledge (C) about cases sometimes taking less time than scheduled applied that information to their response to (B) regarding cases starting late (P = 0.0002). Knowledge of OR efficiency was low among the respondents working in ORs. Nevertheless, the apparent absence of bias shows that education may influence behavior. In contrast, presence of bias on matters of tardiness of start times shows that education may be of no benefit. As the latter results match findings of previous studies of scheduling decisions, interventions to reduce patient and surgeon waiting from start times may depend principally on the application of automation to guide decision-making.

Recently, many concepts, in which passive and simplified functions are actively adapted, have been proposed for the next generation LWRs. The natural circulation BWR is one such considered from the requirements for next generation LWRs as compared with current BWRs. It is pointed out from this consideration that a thermo-hydraulic instability, which may appear during start-up, greatly influences concept feasibility because its occurence makes operation for raising power output difficult. Thermo-hydraulic instabilities are investigated experimentally under conditions simulating normal and abnormal start-up processes. It is clarified that three kinds of thermo-hydraulic instabilities may occur during start-up in the natural circulation BWR according to its procedure and reactor configuration, which are (1) geysering induced by condensation, (2) natural circulation instability induced by hydrostatic head fluctuation in steam separators and (3) density wave instability. Driving mechanisms of the geysering and the natural circulation instability, which have never understood enough, are inferred from the results. Finally, the difference of thermo-hydraulic behavior during start-up processes between thermal natural circulation boilers and the Dodewaard reactor is discussed. (author)

Maintaining a healthy ecosystem is essential for maximizing sustainable ecological services of the best quality to human beings. Ecological and conservation research has provided a strong scientific background on identifying ecological health indicators and correspondingly making effective conservation plans. At the same time, ecologists have asserted a strong need for spatially explicit and temporally effective ecosystem health assessments based on remote sensing data. Currently, remote sensing of ecosystem health is only based on one ecosystem attribute: vigor, organization, or resilience. However, an effective ecosystem health assessment should be a comprehensive and dynamic measurement of the three attributes. This paper reviews opportunities of remote sensing, including optical, radar, and LiDAR, for directly estimating indicators of the three ecosystem attributes, discusses the main challenges to develop a remote sensing-based spatially-explicit comprehensive ecosystem health system, and provides some future perspectives. The main challenges to develop a remote sensing-based spatially-explicit comprehensive ecosystem health system are: (1) scale issue; (2) transportability issue; (3) data availability; and (4) uncertainties in health indicators estimated from remote sensing data. However, the Radarsat-2 constellation, upcoming new optical sensors on Worldview-3 and Sentinel-2 satellites, and improved technologies for the acquisition and processing of hyperspectral, multi-angle optical, radar, and LiDAR data and multi-sensoral data fusion may partly address the current challenges.

Modeling Common-Sense Decisions in Artificial Intelligence

A methodology has been conceived for efficient synthesis of dynamical models that simulate common-sense decision- making processes. This methodology is intended to contribute to the design of artificial-intelligence systems that could imitate human common-sense decision making or assist humans in making correct decisions in unanticipated circumstances. This methodology is a product of continuing research on mathematical models of the behaviors of single- and multi-agent systems known in biology, economics, and sociology, ranging from a single-cell organism at one extreme to the whole of human society at the other extreme. Earlier results of this research were reported in several prior NASA Tech Briefs articles, the three most recent and relevant being Characteristics of Dynamics of Intelligent Systems (NPO -21037), NASA Tech Briefs, Vol. 26, No. 12 (December 2002), page 48; Self-Supervised Dynamical Systems (NPO-30634), NASA Tech Briefs, Vol. 27, No. 3 (March 2003), page 72; and Complexity for Survival of Living Systems (NPO- 43302), NASA Tech Briefs, Vol. 33, No. 7 (July 2009), page 62. The methodology involves the concepts reported previously, albeit viewed from a different perspective. One of the main underlying ideas is to extend the application of physical first principles to the behaviors of living systems. Models of motor dynamics are used to simulate the observable behaviors of systems or objects of interest, and models of mental dynamics are used to represent the evolution of the corresponding knowledge bases. For a given system, the knowledge base is modeled in the form of probability distributions and the mental dynamics is represented by models of the evolution of the probability densities or, equivalently, models of flows of information. Autonomy is imparted to the decisionmaking process by feedback from mental to motor dynamics. This feedback replaces unavailable external information by information stored in the internal knowledge base. Representation

Symbiotic Sensing for Energy-Intensive Tasks in Large-Scale Mobile Sensing Applications.

Energy consumption is a critical performance and user experience metric when developing mobile sensing applications, especially with the significantly growing number of sensing applications in recent years. As proposed a decade ago when mobile applications were still not popular and most mobile operating systems were single-tasking, conventional sensing paradigms such as opportunistic sensing and participatory sensing do not explore the relationship among concurrent applications for energy-intensive tasks. In this paper, inspired by social relationships among living creatures in nature, we propose a symbiotic sensing paradigm that can conserve energy, while maintaining equivalent performance to existing paradigms. The key idea is that sensing applications should cooperatively perform common tasks to avoid acquiring the same resources multiple times. By doing so, this sensing paradigm executes sensing tasks with very little extra resource consumption and, consequently, extends battery life. To evaluate and compare the symbiotic sensing paradigm with the existing ones, we develop mathematical models in terms of the completion probability and estimated energy consumption. The quantitative evaluation results using various parameters obtained from real datasets indicate that symbiotic sensing performs better than opportunistic sensing and participatory sensing in large-scale sensing applications, such as road condition monitoring, air pollution monitoring, and city noise monitoring.

To solve the problem that the remote sensing image segmentation speed is slow and the real-time performance is poor, this paper studies the method of remote sensing image segmentation based on Hadoop platform. On the basis of analyzing the structural characteristics of Hadoop cloud platform and its component MapReduce programming, this paper proposes a method of image segmentation based on the combination of OpenCV and Hadoop cloud platform. Firstly, the MapReduce image processing model of Hadoop cloud platform is designed, the input and output of image are customized and the segmentation method of the data file is rewritten. Then the Mean Shift image segmentation algorithm is implemented. Finally, this paper makes a segmentation experiment on remote sensing image, and uses MATLAB to realize the Mean Shift image segmentation algorithm to compare the same image segmentation experiment. The experimental results show that under the premise of ensuring good effect, the segmentation rate of remote sensing image segmentation based on Hadoop cloud Platform has been greatly improved compared with the single MATLAB image segmentation, and there is a great improvement in the effectiveness of image segmentation.

At their summit meeting in the spring of 1990, Presidents Bush and Gorbachev issued a joint statement expressing their intentions to continue the process of strategic arms control beyond the Strategic Arms Reduction Treaty (START), which was eventually signed in July 1991, toward agreement on further reductions. They set general goals for negotiation of a follow-on treaty to START, which has been called START II. President Bush`s historic speech on September 27, 1991, reinforced those goals and specified several actions the US would take. It is the purpose of this report to examine possible provisions of START II and the implications of those provisions for achievement of the goals set at the 1990 summit, for verifiability, and for US force planning. This look ahead will contribute to advance planning of appropriate negotiating positions, verification research and development (R&D), and force modernization and restructuring. This report describes the goals for a START II treaty and possible means for achieving them. It postulates one set of provisions for such a treaty, while it examines force structures for the US that could result from adoption of a treaty with these provisions. The adequacy of methods for verifying START II are examined and the implications of a START II treaty are postulated.

Making sense of loss: Situating the Mumbai attacks of 26/11 in the context of altruistic suicide homicide

Full Text Available A peculiar irony characterizes the perception of global terrorism—in the strong penchant to flavor it with ethno or religious centric biases or in the disavowal of any auxiliary circumstance leading up to the sporadic incidence of violence. This paper analyzes the Mumbai attacks of November 26th, 2009 from the context of altruistic suicide/homicide. The waging of war against anonymous targets in Mumbai was by all means impersonal. It could be connected to an aftermath of several factors: Kashmir, homegrown terrorism, backlash of sectarian groups or yet another manifestation of already hostile Indo-Pak relationships. The spectacle of terror that was life telecast by national and global media led to a sequel of reactions including a follow-up of Indo-Pak mutual accusations, evoking of national sentiments and analytical ruptures in south Asian intelligentsia in making sense of the loss. This paper situates the Mumbai attacks of 26/11 in the theoretical discourse on sociology of terrorism by (i providing a scholastic definition of terrorism and its corresponding attributes that distinguishes terrorism from other sporadic acts of violence, (ii reflects on the context of terrorism with reference to altruism as in the classical Durkhiemian tradition and (iii analytically moves beyond the classical paradigm to redefine the terror trails of 26/11 within the emerging definitions of altruistic-suicide-homicide.

Philosophy vs the common sense

2017-01-01

Full Text Available The paper deals with the antinomy of philosophy and the common sense. Philosophy emerges as a way of specifically human knowledge, which purposes analytics of the reality of subjective experience. The study reveals that in order to alienate philosophy from the common sense it was essential to revise the understanding of wisdom. The new, philosophical interpretation of wisdom – offered by Pythagoras – has laid the foundation of any future philosophy. Thus, philosophy emerges, alienating itself from the common sense, which refers to the common or collective experience. Moreover, the study examines the role of emotions, conformity and conventionality which they play with respect to the common sense. Next the author focuses on the role of philosophical intuition, guided with principles of rationality, nonconformity and scepticism, which the author professes the foundation stones of any sound philosophy. The common sense, described as deeply routed in the world of human emotions, aims at empathy, as the purpose of philosophy is to provide the rational means of knowledge. Therefore, philosophy uses thinking, keeping the permanent efforts to check and recheck data of its own experience. Thus, the first task of philosophical thinking appears to overcome the suggestion of the common sense, which purposes the social empathy, as philosophical intuition aims at independent thinking, the analytics of subjective experience. The study describes the fundamental principles of the common sense, on the one hand, and those of philosophy, on the other. The author arrives to conclusion that the common sense is unable to exceed the limits of sensual experience. Even there, where it apparently rises to a form of any «spiritual unity», even there it cannot avoid referring to the data of commonly shared sensual experience; though, philosophy, meanwhile, goes beyond sensuality, creating a discourse that would be able to alienate from it, and to make its rational

Colorimetric and Fluorescent Bimodal Ratiometric Probes for pH Sensing of Living Cells.

pH measurement is widely used in many fields. Ratiometric pH sensing is an important way to improve the detection accuracy. Herein, five water-soluble cationic porphyrin derivatives were synthesized and their optical property changes with pH value were investigated. Their pH-dependent assembly/disassembly behaviors caused significant changes in both absorption and fluorescence spectra, thus making them promising bimodal ratiometric probes for both colorimetric and fluorescent pH sensing. Different substituent identity and position confer these probes with different sensitive pH-sensing ranges, and the substituent position gives a larger effect. By selecting different porphyrins, different signal intensity ratios and different fluorescence excitation wavelengths, sensitive pH sensing can be achieved in the range of 2.1-8.0. Having demonstrated the excellent reversibility, good accuracy and low cytotoxicity of the probes, they were successfully applied in pH sensing inside living cells. © 2015 WILEY-VCH Verlag GmbH & Co.
