    Rhyming words, as in songs or poems, is a universal feature of human language across all ages. In the present fMRI study a novel overt rhyming task was applied to determine the neural correlates of rhyme production. Fifteen right-handed healthy male volunteers participated in this verbal fluency study. Participants were instructed to overtly articulate as many words as possible either to a given initial letter (LVF) or to a semantic category (SVF). During the rhyming verbal fluency task (RVF), participants had to generate words that rhymed with pseudoword stimuli. On-line overt verbal responses were audiotaped in order to correct the imaging results for the number of generated words. Fewer words were generated in the rhyming compared to both the lexical and the semantic condition. On a neural level, all language tasks activated a language network encompassing the left inferior frontal gyrus, the middle and superior temporal gyri as well as the contralateral right cerebellum. Rhyming verbal fluency compared to both lexical and semantic verbal fluency demonstrated significantly stronger activation of left inferior parietal region. Generating novel rhyme words seems to be mainly mediated by the left inferior parietal lobe, a region previously found to be associated with meta-phonological as well as sub-lexical linguistic processes.

    Full Text Available During early literacy skills development, rhyming is an important indicator of the phonological precursors required for reading. To determine if neural signatures of rhyming are apparent in early childhood, we recorded event-related potentials (ERPs from 3- to 5-year-old, preliterate children (N = 62 in an auditory prime-target nonword rhyming paradigm (e.g., bly-gry, blane-vox. Overall, nonrhyming targets elicited a larger negativity (N450 than rhyming targets over posterior regions. In contrast, rhyming targets elicited a larger negativity than nonrhyming targets over fronto-lateral sites. The amplitude of the two rhyming effects was correlated, such that a larger posterior effect occurred with a smaller anterior effect. To determine whether these neural signatures of rhyming related to phonological awareness, we divided the children into two groups based on phonological awareness scores while controlling for age and socioeconomic status. The posterior rhyming effect was stronger and more widely distributed in the group with better phonological awareness, whereas differences between groups for the anterior effect were small and not significant. This pattern of results suggests that the rhyme processes indexed by the anterior effect are developmental precursors to those indexed by the posterior effect. Overall, these findings demonstrate early establishment of distributed neurocognitive networks for rhyme processing.

  5. Ambiguity effects of rhyme and meter.

    Previous research has shown that rhyme and meter-although enhancing prosodic processing ease and memorability-also tend to make semantic processing more demanding. Using a set of rhymed and metered proverbs, as well as nonrhymed and nonmetered versions of these proverbs, the present study reveals this hitherto unspecified difficulty of comprehension to be specifically driven by perceived ambiguity. Roman Jakobson was the 1st to propose this hypothesis, in 1960. He suggested that "ambiguity is an intrinsic, inalienable feature" of "parallelistic" diction of which the combination of rhyme and meter is a pronounced example. Our results show that ambiguity indeed explains a substantial portion of the rhyme- and meter-driven difficulty of comprehension. Longer word-reading times differentially reflected ratings for ambiguity and comprehension difficulty. However, the ambiguity effect is not "inalienable." Rather, many rhymed and metered sentences turned out to be low in ambiguity. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Full Text Available Abstract MAKNA DAN BENTUK DALAM PENERJEMAHAN LAGU-LAGU ANAK Abstract Translating nursery rhymes is not an easy task. The problems of equivalence in meaning and form as well as in the harmony between the translated lyrics and the music are aspects that need to be considered by the translators. By considering nursery rhyme lyric as poetry text, this research analyzes the equivalence of meaning and form in nursery rhymes translation. This research focuses on five nursery rhymes. The meaning analysis was done by conducting particular procedures on translation quality assessment. Meanwhile, the analysis of the form was conducted by comparing the two versions of the nursery rhymes focusing on the sound values. From the equivalence of meaning, the result shows that most nursery rhymes are translated less accurately. On the other hand, the finding of the equivalence in form shows that most of the auditory devices are deleted while most of the rhymes are shifted. This research is expected to give a contribution to song translation activities especially those involving children as the target listeners.

    This study investigated the rhyme-as-reason effect on new artificially created advertising slogans. Rhymes and non-rhymes were in Experiment 1 and 2 compared in a between-subjects design and in Experiment 3 in a within-subjects design. The quality of the form and content of the slogans was always evaluated by separate groups. In Experiment 1, we found a strong preference for rhyming slogans as opposed to their non-rhyming counterparts. Rhymes were rated as more likeable, more original, easier to remember, more suitable for campaigns, more persuasive and more trustworthy. In Experiment 2, social advertising messages were evaluated favorably in both rhyming and non-rhyming versions. However, when participants directly compared rhymes and non-rhymes on the same scale (Experiment 3), the difference between commercial and social advertising disappeared and for all slogans rhymes were clearly preferred to non-rhymes in terms of both form and content. A detailed analysis revealed that the rhymes scoring high on formal aspects were also favored in the questionnaire investigating content aspects. © 2013 The Scandinavian Psychological Associations.

    Background: In fMRI examinations, it is very important to select appropriate paradigms assessing the brain function of interest. In addition, the patients' ability to perform the required cognitive tasks during fMRI must be taken into account. Purpose: To evaluate two language paradigms, word generation and sentence reading for their usefulness in examinations of aphasic patients and to make suggestions for improvements of clinical fMRI. Material and Methods: Five patients with aphasia after stroke or trauma sequelae were examined by fMRI. The patients' language ability was screened by neurolinguistic tests and elementary pre-fMRI language tests. Results: The sentence-reading paradigm succeeded to elicit adequate language-related activation in perilesional areas whereas the word generation paradigm failed. These findings were consistent with results on the behavioral tests in that all patients showed very poor performance in phonemic fluency, but scored well above mean at a reading comprehension task. Conclusion: The sentence-reading paradigm is appropriate to assess language function in this patient group, while the word-generation paradigm seems to be inadequate. In addition, it is crucial to use elementary pre-fMRI language tests to guide the fMRI paradigm decision.

    Metrical patterning and rhyme are frequently employed in poetry but also in infant-directed speech, play, rites, and festive events. Drawing on four line-stanzas from nineteenth and twentieth German poetry that feature end rhyme and regular meter, the present study tested the hypothesis that meter and rhyme have an impact on aesthetic liking, emotional involvement, and affective valence attributions. Hypotheses that postulate such effects have been advocated ever since ancient rhetoric and poetics, yet they have barely been empirically tested. More recently, in the field of cognitive poetics, these traditional assumptions have been readopted into a general cognitive framework. In the present experiment, we tested the influence of meter and rhyme as well as their interaction with lexicality in the aesthetic and emotional perception of poetry. Participants listened to stanzas that were systematically modified with regard to meter and rhyme and rated them. Both rhyme and regular meter led to enhanced aesthetic appreciation, higher intensity in processing, and more positively perceived and felt emotions, with the latter finding being mediated by lexicality. Together these findings clearly show that both features significantly contribute to the aesthetic and emotional perception of poetry and thus confirm assumptions about their impact put forward by cognitive poetics. The present results are explained within the theoretical framework of cognitive fluency, which links structural features of poetry with aesthetic and emotional appraisal.

    Full Text Available  Abstract  In pre-Islamic Persian syllabic poem, rhyme has not played an important role and, firstly, the science of rhyme has been collected for Arabic poem and then it has been developed in Persian language. Due to its special position in poem, rhyme is effective in rhythm of poem and selecting it can be phonetically and semantically effective in giving worth to poem. Always, poets and scholars of Persian language have recognized rhyme as an external force that help the poem and subject of rhyme, its range and relationship with the nature of poem have been highly considered as far as different forms of poem are differentiated from each other through the position that rhyme is used in them. Showing Nizami's art of using rhyme in composing Khosrow and Shirin poem and hidden values in it have been led to reveal the prominence of this work among the works of Nizami and even the works that have been composed in imitating it. To study poem rhyme, whether at the level of rhyme letters or rhyme words, can greatly explain the ability and the creative power of poet in the art of poem. However, this ability can be more obvious by studying other parts of rhythm i.e. external and internal rhythm. In poem of Khosrow and Shirin of Nizami, the speaker artistically uses this ability in poem and shows his uniqueness through rhyme lyric. Using long and verb rhymes and usefully well-known rhymes such as (an, ar, a, nad and also using clear and fluent letters such as "R", "M", "N", "Sh" or vowels like "A" and "Ey" are rhythm lyrical factors of Nizami poetry in this poem. In Khosrow and Shirin of Nizami, rhyme is strong and it is rarely appeared in pun form and it is more in rhyming prose (Saj (it must be noted that pun is more rhythmic than rhyming prose. Various rhymes are used in this poem and the main cause of this variety relates to its poetic form i.e. Masnavi and this increases the lyric of poem.  Skillfully using verbal and spiritual novel figures

    2011-01-01

    The path towards energy sustainability is commonly referred to the incremental adoption of available technologies, practices and policies that may help to decrease the environmental impact of energy sector, while providing an adequate standard of energy services. The evaluation of trade-offs among technologies, practices and policies for the mitigation of environmental problems related to energy resources depletion requires a deep knowledge of the local and global effects of the proposed solutions. While attempting to calculate such effects for a large complex system like a city, an advanced multidisciplinary approach is needed to overcome difficulties in modeling correctly real phenomena while maintaining computational transparency, reliability, interoperability and efficiency across different levels of analysis. Further, a methodology that rationally integrates different computational models and techniques is necessary to enable collaborative research in the field of optimization of energy efficiency strategies and integration of renewable energy systems in urban areas. For these reasons, a selection of currently available models for distributed generation planning and design is presented and analyzed in the perspective of gathering their capabilities in an optimization framework to support a paradigm shift in urban energy systems. This framework embodies the main concepts of a local energy management system and adopts a multicriteria perspective to determine optimal solutions for providing energy services through distributed generation.

    2017-06-01

    Full Text Available The present study was an attempt to investigate the effect of nursery rhymes on the young language learners listening comprehension ability. To do so, 30 elementary learners were selected as the potential participants of the study. The learners’ perceptions about using nursery rhymes in teaching listening as well as teachers’ perceptions about teaching listening comprehension through nursery rhymes were taken into account. The listening pre- and post-tests and teachers and learners’ interviews were employed for data collection procedures. Quantitative as well as qualitative methodologies were adapted for data analysis. Findings showed that the young learners could improve their listening comprehension ability as a result of using nursery rhymes. Interview data also indicated that the learners’ perceptions about nursery rhymes were found to be positive since the rhymes provided an interesting atmosphere for the learners to improve their listening comprehension while benefiting from peer interaction and teacher’s support in the listening classroom. Teachers’ perceptions were also realistic regarding using nursery rhymes in teaching listening, especially for young learners. As to the implication side, finding can contribute to the positive application of nursery rhymes in paving the way for young learners to improve their listening comprehension ability.

Rhymes are 'short children's songs that serve to counting children at play, which at the same time can be very suitable for developing a sense of rhythm' (Pedagogical Lexicon, 1996, pp. 56. There are several types of nursery rhymes and their classification according to different criteria. They can be classified according to form and content, as well as whether their authors are children or adults. The criterion of understanding classifies them into rhymes rational sense, irrational - meaningless, and rhymes with a partial sense (see examples of rhymes at Milenkovic & Dragojevic, 2009. According to an embodiment - the musical component rhymes are classified in the speaking which develops a sense of rhythm and sung, whose melodic movement of the highest in the fourth volume.

There are many advantages that rhymes processing brings: the development of speech and speech creativity, encourage foreign language learning, developing communication skills, emotional and social maturation, encouraging cultural‚ awareness, developing ethical and moral values, exploring the contents of nature and society. In selecting the nursery rhymes, it is necessary to pay attention to mental and physical development of children and to adjust the selected rhymes to their age.

    2015-01-01

    While discourse about care and caring is well developed in the UK, the nature of knowledge generation about care and the research paradigms that underpin it have been subjected to limited critical reflection and analysis. An overarching synthesis of evidence - intended to promote debate and facilitate new understandings - identifies two largely separate bodies of carer-related research. The first body of work - referred to as Gathering and Evaluating - provides evidence of the extent of care-giving, who provides care to whom and with what impact; it also focuses on evaluating policy and service efficacy. This type of research tends to dominate public perception about caring, influences the type and extent of policy and support for carers and attracts funding from policy and health-related sources. However, it also tends to be conceptually and theoretically narrow, has limited engagement with carers' perspectives and adopts an atomistic purview on the care-giving landscape. The second body of work - Conceptualising and Theorising - explores the conceptual and experiential nature of care and aims to extend thinking and theory about caring. It is concerned with promoting understanding of care as an integral part of human relationships, embedded in the life course, and a product of interdependence and reciprocity. This work conceptualises care as both an activity and a disposition and foregrounds the development of an 'ethic of care', thereby providing a perspective within which to recognise both the challenges care-giving may present and the significance of care as a normative activity. It tends to be funded from social science sources and, while strong in capturing carers' experiences, has limited policy and service-related purchase. Much could be gained for citizens, carers and families, and the generation of knowledge advanced, if the two bodies of research were integrated to a greater degree. © 2014 John Wiley & Sons Ltd.

    The University of California, Los Angeles (UCLA) School of Dentistry has implemented a Health Resources and Services Administration-funded program to prepare dentists for the complex and comprehensive needs of pediatric patients within rapidly changing demographics and a paradigm shift in dentistry. Traditional dental education has focused on how to respond to oral disease, whereas UCLA's program shifts the paradigm to emphasize early assessment, risk-based prevention, and disease management. A holistic approach to dental care that considers social and environmental determinants is used with minimally invasive techniques for restorative care. To support this change, pediatric dental residents receive traditional training combined with new didactics, advocacy opportunities, and applied learning experiences at community-based organizations. These new elements teach residents to recognize the causal factors of disease and to identify interventions that promote oral health at the individual, family, community, and policy level. Consequently, they are better prepared to treat a diverse group of patients who historically have faced the greatest burden of disease as well as an increased number of barriers to accessing oral health care; these consist of low-income, minority, and/or pediatric populations including children with special health needs. The program's ultimate goal is for residents to deploy these skills in treating vulnerable populations and to demonstrate greater interest in collaborating with non-dental health providers and community organizations to increase access to dental services in private or public health practice settings.

  6. Enhanced activation of the left inferior frontal gyrus in deaf and dyslexic adults during rhyming.

    Hearing developmental dyslexics and profoundly deaf individuals both have difficulties processing the internal structure of words (phonological processing) and learning to read. In hearing non-impaired readers, the development of phonological representations depends on audition. In hearing dyslexics, many argue, auditory processes may be impaired. In congenitally profoundly deaf individuals, auditory speech processing is essentially absent. Two separate literatures have previously reported enhanced activation in the left inferior frontal gyrus in both deaf and dyslexic adults when contrasted with hearing non-dyslexics during reading or phonological tasks. Here, we used a rhyme judgement task to compare adults from these two special populations to a hearing non-dyslexic control group. All groups were matched on non-verbal intelligence quotient, reading age and rhyme performance. Picture stimuli were used since this requires participants to generate their own phonological representations, rather than have them partially provided via text. By testing well-matched groups of participants on the same task, we aimed to establish whether previous literatures reporting differences between individuals with and without phonological processing difficulties have identified the same regions of differential activation in these two distinct populations. The data indicate greater activation in the deaf and dyslexic groups than in the hearing non-dyslexic group across a large portion of the left inferior frontal gyrus. This includes the pars triangularis, extending superiorly into the middle frontal gyrus and posteriorly to include the pars opercularis, and the junction with the ventral precentral gyrus. Within the left inferior frontal gyrus, there was variability between the two groups with phonological processing difficulties. The superior posterior tip of the left pars opercularis, extending into the precentral gyrus, was activated to a greater extent by deaf than dyslexic

    2007-12-01

    Full Text Available This paper aims to join marking the fiftieth anniversary of generativelinguistics by focusing on some principal contributions the field has given to science in general. In the first part of the paper, I discuss the issue of 'modern linguistics', as it is widely taught in local universities, and examine the importance of the generative school in this notion of modernity. In the second part, I analyze the fundamental conceptions and epistemological framework of this school in the study of language, pinpointing fifteen legacies it seems to have already left to human thought, as follows: breakup withbehaviourism; reinstitution of the hypothetico-deductive method; elaboration of the mind-body issue; revival of the thesis that the only true reality is that of the human mind; reintroduction and extension of the term 'cognitive'; participation in rapidterminological changes in the social sciences; return to the problem of language universals with a strong focus on the genetic origins of language faculty; extended usage of the term 'grammar'; contribution to the deletion of clear boundaries between the natural and social sciences, especially in psychology; rise of reductionism in formalsciences; return to the once forgotten Gestalt principles of perception; radical breakup between lexical and sentence semantics; neo-Darwinism; rise of neuroscience; impetus to the foundation of new fields, often multidisciplinary ones. Reconciliation of cognitiveand generative linguistics in the future is anticipated.

  9. Visual working memory modulates low-level saccade target selection: Evidence from rapidly generated saccades in the global effect paradigm

    Hollingworth, Andrew; Matsukura, Michi; Luck, Steven J.

    2013-01-01

    In three experiments, we examined the influence of visual working memory (VWM) on the metrics of saccade landing position in a global effect paradigm. Participants executed a saccade to the more eccentric object in an object pair appearing on the horizontal midline, to the left or right of central fixation. While completing the saccade task, participants maintained a color in VWM for an unrelated memory task. Either the color of the saccade target matched the memory color (target match), the color of the distractor matched the memory color (distractor match), or the colors of neither object matched the memory color (no match). In the no-match condition, saccades tended to land at the midpoint between the two objects: the global, or averaging, effect. However, when one of the two objects matched VWM, the distribution of landing position shifted toward the matching object, both for target match and for distractor match. VWM modulation of landing position was observed even for the fastest quartile of saccades, with a mean latency as low as 112 ms. Effects of VWM on such rapidly generated saccades, with latencies in the express-saccade range, indicate that VWM interacts with the initial sweep of visual sensory processing, modulating perceptual input to oculomotor systems and thereby biasing oculomotor selection. As a result, differences in memory match produce effects on landing position similar to the effects generated by differences in physical salience. PMID:24190909

    In three experiments, we examined the influence of visual working memory (VWM) on the metrics of saccade landing position in a global effect paradigm. Participants executed a saccade to the more eccentric object in an object pair appearing on the horizontal midline, to the left or right of central fixation. While completing the saccade task, participants maintained a color in VWM for an unrelated memory task. Either the color of the saccade target matched the memory color (target match), the color of the distractor matched the memory color (distractor match), or the colors of neither object matched the memory color (no match). In the no-match condition, saccades tended to land at the midpoint between the two objects: the global, or averaging, effect. However, when one of the two objects matched VWM, the distribution of landing position shifted toward the matching object, both for target match and for distractor match. VWM modulation of landing position was observed even for the fastest quartile of saccades, with a mean latency as low as 112 ms. Effects of VWM on such rapidly generated saccades, with latencies in the express-saccade range, indicate that VWM interacts with the initial sweep of visual sensory processing, modulating perceptual input to oculomotor systems and thereby biasing oculomotor selection. As a result, differences in memory match produce effects on landing position similar to the effects generated by differences in physical salience.

    Full Text Available Objective: A research was conducted to assess the phonological awareness in hearing-impaired children in comparison to normal children. In this context, we discussed about the ability of these children in identification of rhyme and word segmentation to syllables. Method and Material: The sample of this study is composed of 320 children, 160 normal & 160 hearing-impaired with a hearing-loss. Of over 70 dB, studying in the 1st t 4th grade of the primary schools in Tehran. They are divided into two groups at each level (20 girls & 20 boys. Results: 1 Hearing-impaired children's scores on test related to rhyme and syllable is lower as compared with normal children. 2 Hearing-impaired children are more potent on test of word segmentation to syllables in comparison to that related to rhyme, while normal children are more successful on test of word segmentation to syllables as compared with that related to rhyme. Discussion: Hearing is an important factor in phonological awareness. Formal education at special schools doesn't compensate for the hearing impairment as to development of the phonological awareness.

    Word durations convey many types of linguistic information, including intrinsic lexical features like length and frequency and contextual features like syntactic and semantic structure. The current study was designed to investigate whether hierarchical metric structure and rhyme predictability account for durational variation over and above other features in productions of a rhyming, metrically-regular children's book: The Cat in the Hat (Dr. Seuss, 1957). One-syllable word durations and inter-onset intervals were modeled as functions of segment number, lexical frequency, word class, syntactic structure, repetition, and font emphasis. Consistent with prior work, factors predicting longer word durations and inter-onset intervals included more phonemes, lower frequency, first mention, alignment with a syntactic boundary, and capitalization. A model parameter corresponding to metric grid height improved model fit of word durations and inter-onset intervals. Specifically, speakers realized five levels of metric hierarchy with inter-onset intervals such that interval duration increased linearly with increased height in the metric hierarchy. Conversely, speakers realized only three levels of metric hierarchy with word duration, demonstrating that they shortened the highly predictable rhyme resolutions. These results further understanding of the factors that affect spoken word duration, and demonstrate the myriad cues that children receive about linguistic structure from nursery rhymes.

In this paper main question is “whether Sa’di in writing the Golestan, besides of applying rules of this kind of speech in Persian language, has used those characteristics of rhymed prose that exist in the main Arabic rhetoric books?” For this purpose, Characteristics of rhythmic and rhymed prose in Arabic rhetoric books have been examined by using description-annalistic approach, and brief pointing to the situation of Persian rhetoric science. The hypothesis is based on the belief that Golistan’s author uses ideas of Arab rhetorician in composition of this book to strengthen the structure of Harmonious and rhymed prose. The aim of the present study is recognizing that Sa'di in the rhymed prose of Golistan how much has used important Arabic rhetorical resources in the field of word and meaning.

    Arianna Antonielli

    2013-03-01

    Full Text Available This essay addresses Mervyn Peake’s own memories of the Second World War Blitz and their migration into the poetical form of a ballad, The Rhyme of the Flying Bomb, composed in 1947. Abounding with Catholic symbolism, allegories and sea imagery, the poem tells the story of a sailor escaping from London bombing raids and his rescue of a new-born babe from a “golden drain”. The subsequent dialogue between the two protagonists reveals the fragile human side of the sailor and the divine prophetical power of the infant. Their former roles of saviour and rescued finally appear to be both spiritually and physically inverted. Written in alternating rhymes, the poem emphasizes Peake’s strong faith in humanity’s capacity to perform acts of love, despite living “at the height of a world at war”.

  3. Beginning from the End: Strategies of Composition in Lyrical Improvisation with End Rhyme

    2017-03-01

    Full Text Available This essay examines the basic principles of constructing improvised verses with end rhyme in three contemporary cultures: _mandinadhes_, Mallorcan _gloses_, and Finnish freestyle rap. This study is based on ethnographic interviews, in which improvisers analyze their methods of composition. This knowledge is complemented by a textual analysis of examples of performances in the given traditions. Sykäri shows that competent improvisers master complex cognitive methods when they create their lines that end with the poetic device of end rhyme, and in particular when they structure the discourse so that the strong arguments are situated at the end of the structural unit of composition. This “reversed” method witnesses a tendency to use parallel phonic patterns in a way that is largely the opposite of those employed with semantic (or canonical parallelism.

  4. The Next Paradigm

    Bernardo Kastrup

    2018-04-01

    Full Text Available In order to perceive the world, we need more than just raw sensory input: a subliminal paradigm of thought is required to interpret raw sensory data and, thereby, create the objects and events we perceive around ourselves. As such, the world we see reflects our own unexamined, culture-bound assumptions and expectations, which explains why every generation in history has believed that it more or less understood the world. Today, we perceive a world of objects and events outside and independent of mind, which merely reflects our current paradigm of thought. Anomalies that contradict this paradigm have been accumulated by physicists over the past couple of decades, which will eventually force our culture to move to a new paradigm. Under this new paradigm, a form of universal mind will be viewed as nature’s sole fundamental entity. In this paper, I offer a sketch of what the new paradigm may look like.

  5. Rhyme and Word Placement in Storybooks Support High-Level Verb Mapping in 3- to 5-Year-Olds

    2018-06-01

    Full Text Available High-level verbs can be especially challenging for young children to initially map to meaning. This study manipulated the format of a storybook designed to support such verb learning from shared reading. We tested whether 3- to 5-year-olds (n = 38 could remember the referents of eight new verbs when presented as essential actions within a narrative story but with differences in placement. Children were randomly assigned to either a rhymed condition, in which target verbs were heard at the end of rhyming stanzas making them maximally appreciable, or a control condition, where the verbs were presented in the same story, but not in final position or within a rhymed stanza. After hearing the story, each child was given three sets of retention questions testing their identification, demonstration, and production of the target verbs. Children identified and successfully demonstrated more target verbs in the rhymed condition than the control condition, and only in the rhymed condition did children’s initial verb mappings exceed chance. No differences between conditions were found in children’s ability to produce the target verbs, in part because of how often they reverted to more generic terms to describe the actions in the story. Nonetheless, these findings support the hypothesis that giving children maximal support within a storybook reading context can facilitate an initial grasp on challenging verbs.

    This study explored how typically developing 1st grade African American English (AAE) speakers differ from mainstream American English (MAE) speakers in the completion of 2 common phonological awareness tasks (rhyming and phoneme segmentation) when the stimulus items were consonant-vowel-consonant-consonant (CVCC) words and nonwords. Forty-nine 1st graders met criteria for 2 dialect groups: AAE and MAE. Three conditions were tested in each rhyme and segmentation task: Real Words No Model, Real Words With a Model, and Nonwords With a Model. The AAE group had significantly more responses that rhymed CVCC words with consonant-vowel-consonant words and segmented CVCC words as consonant-vowel-consonant than the MAE group across all experimental conditions. In the rhyming task, the presence of a model in the real word condition elicited more reduced final cluster responses for both groups. In the segmentation task, the MAE group was at ceiling, so only the AAE group changed across the different stimulus presentations and reduced the final cluster less often when given a model. Rhyming and phoneme segmentation performance can be influenced by a child's dialect when CVCC words are used.

    Blood oxygen level-dependent functional magnetic resonance imaging (fMRI) has demonstrated its capability to provide comparable results to gold standard intracarotid sodium amobarbital (Wada) testing for preoperative determination of language hemispheric dominance. However, thus far, no consensus has been established regarding which fMRI paradigms are the most effective for the determination of hemispheric language lateralization in specific categories of patients and specific regions of interest (ROIs). Forty-one brain tumor patients who performed four different language tasks - rhyming (R), silent word generation (SWG) sentence completion, and sentence listening comprehension (LC) - for presurgical language mapping by fMRI were included in this study. A statistical threshold-independent lateralization index (LI) was calculated and compared among the paradigms in four different ROIs for language activation: functional Broca's (BA) and Wernicke's areas (WA) as well as larger anatomically defined expressive (EA) and receptive (RA) areas. The two expressive paradigms evaluated in this study are very good lateralizing tasks in expressive language areas; specifically, a significantly higher mean LI value was noted for SWG (0.36 ± 0.25) compared to LC (0.16 ± 0.24, p = 0.009) and for R (0.40 ± 0.22) compared to LC (0.16 ± 0.24, p = 0.001) in BA. SWG LI (0.28 ± 0.19) was higher than LC LI (0.12 ± 0.16, p = 0.01) also in EA. No significant differences in LI were found among these paradigms in WA or RA. SWG and R are sufficient for the determination of lateralization in expressive language areas, whereas new semantic or receptive paradigms need to be designed for an improved assessment of lateralization in receptive language areas.

    2013-06-01

    Sign languages (SL), like oral languages (OL), organize elementary, meaningless units into meaningful semantic units. Our aim was to compare, at behavioral and neurophysiological levels, the processing of the location parameter in French Belgian SL to that of the rhyme in oral French. Ten hearing and 10 profoundly deaf adults performed a rhyme judgment task in OL and a similarity judgment on location in SL. Stimuli were pairs of pictures. As regards OL, deaf subjects' performances, although above chance level, were significantly lower than that of hearing subjects, suggesting that a metaphonological analysis is possible for deaf people but rests on phonological representations that are less precise than in hearing people. As regards SL, deaf subjects scores indicated that a metaphonological judgment may be performed on location. The contingent negative variation (CNV) evoked by the first picture of a pair was similar in hearing subjects in OL and in deaf subjects in OL and SL. However, an N400 evoked by the second picture of the non-rhyming pairs was evidenced only in hearing subjects in OL. The absence of N400 in deaf subjects may be interpreted as the failure to associate two words according to their rhyme in OL or to their location in SL. Although deaf participants can perform metaphonological judgments in OL, they differ from hearing participants both behaviorally and in ERP. Judgment of location in SL is possible for deaf signers, but, contrary to rhyme judgment in hearing participants, does not elicit any N400. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objective: The aim of the present study is to develope and evaluate validity and reliability of Persian version of Dichotic Fused Rhymed Words Test in 18-25 years old normal population. Materials & Methods: The Persian version of Dichotic Fused Rhymed Words Test consisted of 15 pairs of monosyllable rhymed words. These paired words are set in 4 lists of 30 items that simultaneously were presented one to the left and another to the right ear so that they lead to perception of a single fusion concept. After selecting the test material from Moin Persian dictionary according to the intended criteria and pairing the rhymed words, content validity was assessed through lawshe method by 10 expert persons, words with high validity were selected and lists were set. Then, the words of each list were recorded on CD in a dichotic mode. Thereafter, the study was performed in 124 normal individuals (68 females and 56 males within ages ranging from 18 to 25 years and the scores were recorded on a designed scoring form. To examine reliability of test, the test was performed on 15 individuals again two weeks after the initial test and the Pearson correlation was assessed. Results: There are significant differences between mean scores of right and left ears (P<0.001. Content Validity Ratio was 0.8-1 for every item. Pearson correlation was 0.83 for test-retest (P<0.001. Cronbach’s alpha and Intra Class Correlation (ICC was 0.81 and 0.84 for internal correlation between scores of lists of test. The result showed that there is significant correlation between the lists. Conclusion: Based on the obtained results, the Persian version of Dichotic Fused Rhymed Words Test has a good content validity and reliability. It can be used in detecting function of corpus callosum, lateralization of the cerebral hemispheres and assessment of central auditory processing.

  12. Smart grids: A paradigm shift on energy generation and distribution with the emergence of a new energy management business model

    Science.gov (United States)

    Cardenas, Jesus Alvaro

    An energy and environmental crisis will emerge throughout the world if we continue with our current practices of generation and distribution of electricity. A possible solution to this problem is based on the Smart grid concept, which is heavily influenced by Information and Communication Technology (ICT). Although the electricity industry is mostly regulated, there are global models used as roadmaps for Smart Grids' implementation focusing on technologies and the basic generation-distribution-transmission model. This project aims to further enhance a business model for a future global deployment. It takes into consideration the many factors interacting in this energy provision process, based on the diffusion of technologies and literature surveys on the available documents in the Internet as well as peer-reviewed publications. Tariffs and regulations, distributed energy generation, integration of service providers, consumers becoming producers, self-healing devices, and many other elements are shifting this industry into a major change towards liberalization and deregulation of this sector, which has been heavily protected by the government due to the importance of electricity for consumers. We propose an Energy Management Business Model composed by four basic elements: Supply Chain, Information and Communication Technology (ICT), Stakeholders Response, and the resulting Green Efficient Energy (GEE). We support the developed model based on the literature survey, we support it with the diffusion analysis of these elements, and support the overall model with two surveys: one for peers and professionals, and other for experts in the field, based on the Smart Grid Carnegie Melon Maturity Model (CMU SEI SGMM). The contribution of this model is a simple path to follow for entities that want to achieve environmental friendly energy with the involvement of technology and all stakeholders.

  13. Yunnan’s Fast-Paced Large Hydropower Development: A Powershed-Based Approach to Critically Assessing Generation and Consumption Paradigms

    2016-10-01

    Full Text Available Southwest China’s Yunnan province is evolving into one of the world’s largest hydro-power-producing regions. It already rivals the world’s largest hydro-producing nations. However, five of Yunnan’s six basins are international and therefore its hydropower development is of great academic and geopolitical interest. While the implementation of large projects on Yunnan’s three large rivers (Jinsha, Mekong and Nu is relatively well studied, hydropower development outside these three main streams is hardly known. Here, we identified 128 large hydropower projects (≥50 MW having a capacity of 16.5 GW, along with another 16.4 GW of other types of power generation, neither of which has been discussed in the academic literature yet. The paper utilizes a powershed approach to study the rapid hydropower development underway in Yunnan, both in its implication and challenges (at basin and administrative level as well as in its trade-offs within the broader electricity context. Yunnan’s power generation and consumption patterns are characterized by diverging interests of local/provincial usage and export utilization. Within the province, the largest (hydro- power users are energy/electricity intensive industries, which themselves have strong impacts on land use changes. Yunnan is also evolving as a major power exporter, already in 2013 exporting about one-third of its generated electricity mainly to Guangdong’s Pearl River Delta. We see a need for a critical revision of those existing generation and consumption paradigms, which includes a rethinking of major development modes, both in terms of future hydropower generation and utilization projects as well as export obligations.

  14. Membrane paradigm

    International Nuclear Information System (INIS)

    Price, R.H.; Thorne, K.S.

    1986-01-01

    The membrane paradigm is a modified frozen star approach to modeling black holes, with particles and fields assuming a complex, static, boundary-layer type structure (membrane) near the event horizon. The membrane has no effects on the present or future evolution of particles and fields above itself. The mathematical representation is a combination of a formalism containing terms for the shear and bulk viscosity, surface pressure, momentum, temperature, entropy, etc., of the horizon and the 3+1 formalism. The latter model considers a family of three-dimensional spacelike hypersurfaces in one-dimensional time. The membrane model considers a magnetic field threading the hole and undergoing torque from the hole rotation. The field is cleaned by the horizon and distributed over the horizon so that ohmic dissipation is minimized. The membrane paradigm is invalid inside the horizon, but is useful for theoretically probing the properties of slowly evolving black holes

    Dominic L. Palazzolo

    2017-12-01

    Full Text Available Background: While ECIGs are under scrutiny concerning safety, particularly in reference to the physiological impact that aerosolized ECIG liquid (E-liquid may have on respiratory tissues, others believe that ECIGs are a “Harm Reduction” alternative to conventional cigarettes. Previous studies investigating ciliated respiratory epithelium indicate that smoking shortens cilia length, reduces cilia beat frequency and disrupts respiratory epithelium, which most likely contributes to the inhibition of mucocilliary clearance. Monitoring mucous clearance of respiratory tissues exposed to ECIG-generated aerosol or conventional cigarette smoke, as indexed by mucous transport velocity (MTV, is one way to gauge the impact aerosol and smoke have on the respiratory tract. Therefore, we designed an experiment to test the effect of ECIG-generated aerosol and smoke on MTV using the frog palate paradigm.Methods: Peristaltic pumps transport ECIG-generated aerosol and conventional cigarette smoke into custom-made chambers containing excised bullfrog palates.

Surface and cross sectional SEM images of palates from all three groups were obtained to support MTV data.Results: The results indicate that ECIG-generated aerosol has a modest inhibitory effect (p < 0.05 on MTV 1 day post-exposure (0.09 ± 0.01 compared to control MTV (0.16 ± 0.03 mm/s.

    The Callsign Acquisition Test (CAT) is a speech intelligibility test developed by the US Army Research Laboratory. The test has been used to evaluate speech transmission through various communication systems but has not been yet sufficiently standardised and validated. The aim of this study was to compare CAT and Modified Rhyme Test (MRT) performance in the presence of white noise across a range of signal-to-noise ratios (SNRs). A group of 16 normal-hearing listeners participated in the study. The speech items were presented at 65 dB(A) in the background of white noise at SNRs of -18, -15, -12, -9 and -6 dB. The results showed a strong positive association (75.14%) between the two tests, but significant differences between the CAT and MRT absolute scores in the range of investigated SNRs. Based on the data, a function to predict CAT scores based on existing MRT scores and vice versa was formulated. STATEMENT OF RELEVANCE: This work compares performance data of a common speech intelligibility test (MRT) with a new test (CAT) in the presence of white noise. The results here can be used as a part of the standardisation procedures and provide insights to the predictive capabilities of the CAT to quantify speech intelligibility communication in high-noise military environments.

  20. Implicit Forms of Ethnic Insult for Europeans (as Found in Rhyming Slang

    2014-01-01

    Full Text Available The article presents a sociocultural lingual description of ethnic labels created within rhyming slang (Rh.sl. and used to refer to Europeans. The study and description of ethnic stereotypes and labels have attracted attention of researchers due to the practical significance in regulating, controlling and manipulating the direct contacts and interaction between different ethnic groups. The authors have focused their attention on the so-called «hidden» or «implicit» forms of Rh.sl. Along with the explicit, direct, offensive and non-politically correct ethnic labels and nicknames there are quite a few with a deceptive, innocuous shape that conceals their offensive content. That's why they should be perceived as potentially (if not indeed offensive names. The authors put the ethnic labels produced in Rh.sl into this category. Since Rh.sl. is subject to a strong influence of the word play and its items are perceived as humorous and ironic nominations, they are not always discerned as offensive by the English speakers. The article contains a linguistic-and-socio-cultural analysis of some implicit forms of ethnic insult of the Germans, the French, the Italians, the Spaniards, the Portuguese and some other Europeans as well as the native inhabitants of the British Isles. The undertaken analysis of ethnic labels as used to name people from Europe has revealed a broad spectrum of Rh.sl. ethic labels. The description was based on extra-linguistic factors (geographical, demographic, social comprising the settlement and resettlement, compact presence on a certain territory, statehood. In this respect, there is an ethnic group that falls out - the gypsies (or Roma, as they are scattered across the world and still have a nomadic and semi-nomadic way of life.

  1. Predicting Growth in Word Level Reading Skills in Children With Developmental Dyslexia Using an Object Rhyming Functional Neuroimaging Task.

    2016-04-01

    An object rhyming task that does not require text reading and is suitable for younger children was used to predict gains in word level reading skills following an intensive 2-year reading intervention for children with developmental dyslexia. The task evoked activation in bilateral inferior frontal regions. Growth in untimed pseudoword reading was associated with increased pre-intervention activation of the left inferior frontal gyrus, and growth in timed word reading was associated with pre-intervention activation of the left and right inferior frontal gyri. These analyses help identify pre-intervention factors that facilitate reading skill improvements in children with developmental dyslexia.

    2014-02-01

    Experimental genetics with model organisms and mathematically explicit genetic theory are generally considered to be the major paradigms by which progress in genetics is achieved. Here I argue that this view is incomplete and that pivotal advances in genetics--and other fields of biology--are also made by synthesizing disparate threads of extant information rather than generating new information from experiments or formal theory. Because of the explosive expansion of information in numerous "-omics" data banks, and the fragmentation of genetics into numerous subdisciplines, the importance of the synthesis paradigm will likely expand with time.

  11. Next generation paradigm for urban pluvial flood modelling, prediction, management and vulnerability reduction - Interaction between RainGain and Blue Green Dream projects

    Maksimovic, C.

    2012-04-01

    The effects of climate change and increasing urbanisation call for a new paradigm for efficient planning, management and retrofitting of urban developments to increase resilience to climate change and to maximize ecosystem services. Improved management of urban floods from all sources in required. Time scale for well documented fluvial and coastal floods allows for timely response but surface (pluvial) flooding caused by intense local storms had not been given appropriate attention, Pitt Review (UK). Urban surface floods predictions require fine scale data and model resolutions. They have to be tackled locally by combining central inputs (meteorological services) with the efforts of the local entities. Although significant breakthrough in modelling of pluvial flooding was made there is a need to further enhance short term prediction of both rainfall and surface flooding. These issues are dealt with in the EU Iterreg project Rain Gain (RG). Breakthrough in urban flood mitigation can only be achieved by combined effects of advanced planning design, construction and management of urban water (blue) assets in interaction with urban vegetated areas' (green) assets. Changes in design and operation of blue and green assets, currently operating as two separate systems, is urgently required. Gaps in knowledge and technology will be introduced by EIT's Climate-KIC Blue Green Dream (BGD) project. The RG and BGD projects provide synergy of the "decoupled" blue and green systems to enhance multiple benefits to: urban amenity, flood management, heat island, biodiversity, resilience to drought thus energy requirements, thus increased quality of urban life at lower costs. Urban pluvial flood management will address two priority areas: Short Term rainfall Forecast and Short term flood surface forecast. Spatial resolution of short term rainfall forecast below 0.5 km2 and lead time of a few hours are needed. Improvements are achievable by combining data sources of raingauge networks

    词调的平仄通押主要是受音乐及文学两种因素影响的结果。虽然平仄通押词调较少,却可分为多种类型,每种类型的原因各不相同。因为阶层的不同,词人创作的态度、能力及内容、受众的要求、趣味等都有不同,这些造成了诗客曲子词和民间市民词在平仄通押的表现形态并不相同。平仄通押是词曲共有的现象,不是区别词曲的标记。%The co-rhyme of the level and oblique tones in the Ci is mainly affected by music and literature. The number of this kind of Ci is small, but can be divided into a variety of types whose forming reasons are varied. Because of different social stratums, different poets have different creative attitudes, abilities, contents and audience’s requirements and taste are also different. So, there arise different manifestations of the co-rhyme of the level and oblique tones between poets and ordinary citizens in the Ci. The co-rhyme of the level and oblique tones is a common phenomenon rather than a diacritical mark in Ci and Qu.

  18. Winnicott's paradigm outlined

    Directory of Open Access Journals (Sweden)

    Zeljko Loparic

    Full Text Available The main objective of this paper is to present a unified view of Winnicott’s contribution to psychoanalysis. Part I (Sections 1-4 starts off by recalling that, according to some important commentators, Winnicott introduced a change in paradigms in psychoanalysis. In order to show that this change can be viewed as an overall “switch in paradigms”, in the sense given by T. S. Kuhn, this paper presents an account of the Kuhn’s view of science and offers a reconstruction of Freud’s Oedipal, Triangular or “Toddler-in-the-Mother’s-Bed” Paradigm. Part II (Sections 5-13 shows that as early as the 1920’s Winnicott encountered insurmountable anomalies in the Oedipal paradigm and, for that reason, started what can be called revolutionary research for a new framework of psychoanalysis. This research led Winnicott, especially during the last period of his life, to produce an alternative dual or “Baby-on-the-Mother’s-Lap” Paradigm. This new paradigm is described in some detail, especially the paradigmatic dual mother-baby relation and Winnicott’s dominant theory of maturation. Final remarks are made regarding Winnicott’s heritage and the future of psychoanalysis.

  19. Three paradigms of horror

    2016-07-01

    Full Text Available Starting with the definition of horror as a literary genre the core story of which is based on a meeting with threatening Otherness whose influx into consensual reality and it’s tacit normality creates unrest and awakens fear in the protagonists and the audience, this paper defines the three key paradigms of the horror genre, based on the causes of fear, or rather the “monstrous” Otherness in them. Paradigm 1 concerns the “fear of one’s own self”: the root of the fear is inside, in the individual psyche, in the split, deceived, or in some other way unreliable self which is, consciously or unconsciously, harmful to others, and ultimately to itself. Paradigm 2 deals with the “Fear of others”: the root of fear is outside and is concerned with other people and other creatures which have an urge to occupy a certain human microcosm. Paradigm 3 is concerned with the “Fear of the numinous”: the root of the fear is mostly situated on the outside; however its shape is amorphous, ambivalent and unknowable. The “monster” is faceless; it touches on primary forces of the divine/demonic, and as such is situated on the very border between inside/outside. All three paradigms, with their main approaches and constitutive elements, are modulated through two basic possible treatments: the conservative and the progressive (liberal, which affords a total of six basic variations of horror. Starting from definitions given by John Carpenter, Robin Wood and his own, the author analyzes representative examples from horror literature and film for each paradigm and its variation, with a special accent on the image of Otherness and its connection to the norm, its intrusion into the status quo, anthropocentrism and the presence or absence of a happy ending. The paper demonstrates the richness of connotative potential within the horror genre and provides a basis for its taxonomy.

  5. Information processing as a paradigm for decision making.

    Science.gov (United States)

    Oppenheimer, Daniel M; Kelso, Evan

    2015-01-03

    For decades, the dominant paradigm for studying decision making--the expected utility framework--has been burdened by an increasing number of empirical findings that question its validity as a model of human cognition and behavior. However, as Kuhn (1962) argued in his seminal discussion of paradigm shifts, an old paradigm cannot be abandoned until a new paradigm emerges to replace it. In this article, we argue that the recent shift in researcher attention toward basic cognitive processes that give rise to decision phenomena constitutes the beginning of that replacement paradigm. Models grounded in basic perceptual, attentional, memory, and aggregation processes have begun to proliferate. The development of this new approach closely aligns with Kuhn's notion of paradigm shift, suggesting that this is a particularly generative and revolutionary time to be studying decision science.

  7. "Daños, engaños y desengaños, frutos son de los años": the semantic value of rhyme in the Spanish baroque sonnets on the transience of life

    Directory of Open Access Journals (Sweden)

    Špela Oman

    2012-12-01

    Full Text Available One of the most recurring Baroque themes is without a doubt the topic of tempus fugit, which inspired numerous contemplations about the ephemeral nature of life, the brevity of the earthly existence and the omnipresence of death. The obsession with the passing of time in the Spanish Baroque sonnets on the ephemerality of life can also be observed on the level of rhyme, which far from being merely an ornamental item, actually contributes important semantic value to the poem. Rhymes such as años/daños/engaños/desengaños or mañana/vana, jornada/nada reappear almost obsessively throughout the corpus of Baroque poetry and form semantic knots that highlight the principal theme of the sonnet. Similarly, pairs of words such as encina/ruina, vida/desvanecida, humano/gusano, besos/huesos, are closely related despite different meanings, drawing attention to the devastating eff ects of the passage of time. The insatiable quest for suggestive rhymes by Golden Age poets is doubtless due to the aesthetic orientation of Baroque art that tends to combine decorative virtuosity with the intellectual subtlety. The semantic rhyme thus functions as one of the axis of the meaning, as an echo resonating the poetic message, and likewise as a means of fulfilling the Baroque search for thematic unity. The rhyme in the Baroque sonnets is integrated thematically with the text, in the same manner as a pillar supporting a Baroque facade is subjected to the effect of absolute architectural unity.

  8. Active training paradigm for motor imagery BCI.

    Li, Junhua; Zhang, Liqing

    2012-06-01

    Brain-computer interface (BCI) allows the use of brain activities for people to directly communicate with the external world or to control external devices without participation of any peripheral nerves and muscles. Motor imagery is one of the most popular modes in the research field of brain-computer interface. Although motor imagery BCI has some advantages compared with other modes of BCI, such as asynchronization, it is necessary to require training sessions before using it. The performance of trained BCI system depends on the quality of training samples or the subject engagement. In order to improve training effect and decrease training time, we proposed a new paradigm where subjects participated in training more actively than in the traditional paradigm. In the traditional paradigm, a cue (to indicate what kind of motor imagery should be imagined during the current trial) is given to the subject at the beginning of a trial or during a trial, and this cue is also used as a label for this trial. It is usually assumed that labels for trials are accurate in the traditional paradigm, although subjects may not have performed the required or correct kind of motor imagery, and trials may thus be mislabeled. And then those mislabeled trials give rise to interference during model training. In our proposed paradigm, the subject is required to reconfirm the label and can correct the label when necessary. This active training paradigm may generate better training samples with fewer inconsistent labels because it overcomes mistakes when subject's motor imagination does not match the given cues. The experiments confirm that our proposed paradigm achieves better performance; the improvement is significant according to statistical analysis.

    For many years, estuarine science has been the 'poor relation' in aquatic research - freshwater scientists ignored estuaries as they tended to get confused by salt and tides, and marine scientists were more preoccupied by large open systems. Estuaries were merely regarded by each group as either river mouths or sea inlets respectively. For the past four decades, however, estuaries (and other transitional waters) have been regarded as being ecosystems in their own right. Although often not termed as such, this has led to paradigms being generated to summarise estuarine structure and functioning and which relate to both the natural science and management of these systems. This paper defines, details and affirms these paradigms that can be grouped into those covering firstly the science (definitions, scales, linkages, productivity, tolerances and variability) and secondly the management (pressures, valuation, health and services) of estuaries. The more 'science' orientated paradigms incorporate the development and types of ecotones, the nature of stressed and variable systems (with specific reference to resilience and redundancy), the relationship between generalists and specialists produced by environmental tolerance, the relevance of scale in relation to functioning and connectivity, the sources of production and degree of productivity, the biodiversity-ecosystem functioning and the stress-subsidy debates. The more 'management' targeted paradigms include the development and effects of exogenic unmanaged pressures and endogenic managed pressures, the perception of health and the ability to manage estuaries (related to internal and external influences), and the influence of all of these on the production of ecosystem services and societal benefits.

    Full Text Available The words and phrases swop with each other and the apparent stability of a word’s meaning sometimes change in time. This explains why the generic term of accounting is used when referring to the qualities attributed to accounting,but also when it comes to organizing financial accounting function within the entity, and when referring concretely to keeping a double record with its specific means, methods and tools specific, respectively seen as a technical accounting.Speaking about the qualities of accounting, but also about the organizational form it takes, we note that there is a manifold meaning of the word accounting, which is why the purpose of this article is to demonstrate that the paradigm shift aimed at a new set of rules and if the rules changes, then we can change the very purpose of accounting.

    Parasitic species, which depend directly on host species for their survival, represent a major regulatory force in ecosystems and a significant component of Earth's biodiversity. Yet the negative impacts of parasites observed at the host level have motivated a conservation paradigm of eradication, moving us farther from attainment of taxonomically unbiased conservation goals. Despite a growing body of literature highlighting the importance of parasite-inclusive conservation, most parasite species remain understudied, underfunded, and underappreciated. We argue the protection of parasitic biodiversity requires a paradigm shift in the perception and valuation of their role as consumer species, similar to that of apex predators in the mid-20th century. Beyond recognizing parasites as vital trophic regulators, existing tools available to conservation practitioners should explicitly account for the unique threats facing dependent species. We built upon concepts from epidemiology and economics (e.g., host-density threshold and cost-benefit analysis) to devise novel metrics of margin of error and minimum investment for parasite conservation. We define margin of error as the risk of accidental host extinction from misestimating equilibrium population sizes and predicted oscillations, while minimum investment represents the cost associated with conserving the additional hosts required to maintain viable parasite populations. This framework will aid in the identification of readily conserved parasites that present minimal health risks. To establish parasite conservation, we propose an extension of population viability analysis for host-parasite assemblages to assess extinction risk. In the direst cases, ex situ breeding programs for parasites should be evaluated to maximize success without undermining host protection. Though parasitic species pose a considerable conservation challenge, adaptations to conservation tools will help protect parasite biodiversity in the face of

    The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. A multinational patient registry was used to assess long-term changes associated with TRT in middle-age and older men with hypogonadism. Comprehensive evaluations were conducted at 6, 12, 24, and 36 months after enrollment into the registry. QOL and sexual function were evaluated by validated measures, including the Aging Males' Symptom (AMS) Scale and the International Index of Erectile Function (IIEF). A total of 999 previously untreated men with hypogonadism were enrolled at 25 European centers, 750 of whom received TRT at at least one visit during the period of observation. Patients on TRT reported rapid and sustained improvements in QOL, with fewer sexual, psychological, and somatic symptoms. Modest improvements in QOL and sexual function, including erectile function, also were noted in RHYME patients not on TRT, although treated patients showed consistently greater benefit over time in all symptom domains compared with untreated patients. AMS total scores for patients on TRT were 32.8 (95% confidence interval = 31.3-34.4) compared with 36.6 (95% confidence interval = 34.8-38.5) for untreated patients (P treatment. The major strengths are the large, diverse patient population being treated in multidisciplinary clinical settings. The major limitation is the frequency of switching from one formulation to another. Overall, we confirmed the broad and sustained benefits of TRT across major QOL dimensions, including sexual, somatic, and psychological health, which were sustained over 36 months in our treatment cohort.

  18. Revisiting System Paradigms from the Viewpoint of Manufacturing Sustainability

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available A system paradigm is an abstract representation of system; it includes system architecture used to determine the types and numbers of components and their relations in the system. The design of system paradigm relies on customers’ requirements and the characteristics of the manufacturing environment. Many system paradigms and design guidelines have been proposed for a variety of customers’ needs including functions, cost, quality, personalization, and lead time of products. However, the consideration of sustainability becomes essential to today’s manufacturing systems; a new challenge is how to evolve existing paradigms to accommodate the requirements of sustainability. In contrast to ample research activities on system paradigms in past decades, recent studies on system paradigms have been restricted, partially due to unclear research directions. Limited works can be found on conceiving new manufacturing system paradigms from the perspective of sustainability; most of the related literature concerns the new requirements of sustainability. The objectives of this work are (i to examine the requirements of manufacturing systems in a wider scope; (ii to revisit existing paradigms to clarify their limitations and bottlenecks; and eventually (iii to identify some research directions, which will lead to a solution of sustainable manufacturing. To achieve these objectives, firstly, a brief description of today’s manufacturing environment is provided. Secondly, the requirements of sustainability are discussed, and the relevant researches on system sustainability are surveyed. Thirdly, the reconfigurable system paradigm is focused, and the gaps between a reconfigurable manufacturing system and a sustainable manufacturing system are discussed. Finally, the future endeavors towards to the next-generation manufacturing system paradigms are discussed.

  19. Gas transmission : a paradigm shift

    Cornelson, D.W.

    1997-01-01

    The evolution of energy markets in North America was discussed. The investment opportunities that are possible in a deregulated energy market, be it in production or in the generation of energy commodities, in the development of midstream infrastructure, or in the provision of energy services, were outlined. Deregulation of crude oil, natural gas and electricity has resulted in significant changes in the structure of energy markets and the way in which customers are served. One of the advantages of competition regarding power generation is that it has turned energy into a commodity which has resulted in greater customer choice and efficiency. As one example of midstream infrastructure development, the Alliance Pipeline project was described. This project was conceived as a means to enhance the value of western Canadian natural gas. The 1,900 mile pipeline will run from British Columbia, through Alberta into Chicago where it will interconnect with the North American gas transmission grid. The pipeline is an efficient means of transporting energy from Western Canada to North American markets, and Alliance, as a lowest cost transporter, will continue to put pressure on the traditional infrastructure to become even more competitive at the margin. As such, Alliance represents a paradigm shift in energy transportation, and serves as an excellent example of the type of investment opportunity that a deregulated market can provide. It was suggested that innovation and competition in a deregulated North American energy market will continue to increase. As electricity is deregulated, the energy market will respond more quickly to changes in supply and demand than it did in the past, in an effort to satisfy the needs of investors and customers. This will provide increased opportunities for restructuring and further competition

  20. Marketing communications: Qualitative and quantitative paradigm

    2005-01-01

    Full Text Available This paper focuses on key issues in relation to the choice of basic language of communication of marketing as a practical and academic field. Principally, marketing managers prefer descriptive way of expression, but they should use the advantages of language of numbers much more. By doing so, they will advance decision-making process - and the communication with finance and top management. In this regard, models offered by academic community could be helpful. This especially pertains to those positive or normative verbal approaches and models in which mathematics and statistical solutions have been embedded, as well as to those which emphasize financial criteria in decision-making. Concerning the process of creation and verification of scientific knowledge, the choice between languages of words and numbers is the part of much wider dimension, because it is inseparable from the decision on basic research orientation. Quantitative paradigm is more appropriate for hypotheses testing, while qualitative paradigm gives greater contribution in their generation. Competition factor could become the key driver of changes by which existing "parallel worlds" of main paradigms would be integrating, for the sake of disciplinary knowledge advancement.

  2. The rhyme in Marina Tsvetaeva’s ''Poetry of the word'' (with the poem Nebo – sinei znameni! “The sky is bluer than the flag!” as an example

    Directory of Open Access Journals (Sweden)

    2018-12-01

    Full Text Available The aim of this paper is to present one of the main mechanisms of semantic creation in Marina Tsvetaeva’s poetry through the analysis of the poem Небо — синей знамени! (“The Sky is Bluer than the Flag!”, 1935. This text demonstrates the opposition between time and eternity by means of adjoining fi ve nouns which are united by a rather rare infl ectional pattern (neuter nouns with the nominative singular in -мя in rhyming position. The choice of this particular range of vocabulary serves as evidence to the poet’s desire to test the semantic potential of words similar in their declension type rather than in their meaning. In her construction of the text, the language rather than the world is primary, and it is the language that reality is being checked against. The specifi city of this feature to Tsvetaeva’s creative work is proved by examining its realisation in other texts, namely in the poem Променявши на стремя by Tsvetaeva herself and in Akhmatova’s text from the 1960s Из набросков. In the fi rst text, this specifi c rhyming does not cover the whole text, and the theme expressed by its associative range is still one-dimensional. Akhmatova’s poem clearly demonstrates that this technique can be employed in various ways for poetic purposes. The analysis of the text allows us to conclude that the prominence of this technique depends primarily on the role that it plays in expressing the poetic thought, whereas the number of same-type words in the rhyming position is a secondary factor.

  3. Paradigm Shifts in Ophthalmic Diagnostics.

    Sebag, J; Sadun, Alfredo A; Pierce, Eric A

    2016-08-01

    Future advances in ophthalmology will see a paradigm shift in diagnostics from a focus on dysfunction and disease to better measures of psychophysical function and health. Practical methods to define genotypes will be increasingly important and non-invasive nanotechnologies are needed to detect molecular changes that predate histopathology. This is not a review nor meant to be comprehensive. Specific topics have been selected to illustrate the principles of important paradigm shifts that will influence the future of ophthalmic diagnostics. It is our impression that future evaluation of vision will go beyond visual acuity to assess ocular health in terms of psychophysical function. The definition of disease will incorporate genotype into what has historically been a phenotype-centric discipline. Non-invasive nanotechnologies will enable a paradigm shift from disease detection on a cellular level to a sub-cellular molecular level. Vision can be evaluated beyond visual acuity by measuring contrast sensitivity, color vision, and macular function, as these provide better insights into the impact of aging and disease. Distortions can be quantified and the psychophysical basis of vision can be better evaluated than in the past by designing tests that assess particular macular cell function(s). Advances in our understanding of the genetic basis of eye diseases will enable better characterization of ocular health and disease. Non-invasive nanotechnologies can assess molecular changes in the lens, vitreous, and macula that predate visible pathology. Oxygen metabolism and circulatory physiology are measurable indices of ocular health that can detect variations of physiology and early disease. This overview of paradigm shifts in ophthalmology suggests that the future will see significant improvements in ophthalmic diagnostics. The selected topics illustrate the principles of these paradigm shifts and should serve as a guide to further research and development. Indeed

  10. New Indivisible Planetary Science Paradigm: Consequence of Questioning Popular Paradigms

    Science.gov (United States)

    Marvin Herndon, J.

    2014-05-01

    Progress in science involves replacing less precise understanding with more precise understanding. In science and in science education one should always question popular ideas; ask "What's wrong with this picture?" Finding limitations, conflicts or circumstances that require special ad hoc consideration sometimes is the key to making important discoveries. For example, from thermodynamic considerations, I found that the 'standard model of solar system formation' leads to insufficiently massive planetary cores. That understanding led me to discover a new indivisible planetary science paradigm. Massive-core planets formed by condensing and raining-out from within giant gaseous protoplanets at high pressures and high temperatures, accumulating heterogeneously on the basis of volatility with liquid core-formation preceding mantle-formation; the interior states of oxidation resemble that of the Abee enstatite chondrite. Core-composition was established during condensation based upon the relative solubilities of elements, including uranium, in liquid iron in equilibrium with an atmosphere of solar composition at high pressures and high temperatures. Uranium settled to the central region and formed planetary nuclear fission reactors, producing heat and planetary magnetic fields. Earth's complete condensation included a ~300 Earth-mass gigantic gas/ice shell that compressed the rocky kernel to about 66% of Earth's present diameter. T-Tauri eruptions, associated with the thermonuclear ignition of the Sun, stripped the gases away from the Earth and the inner planets. The T-Tauri outbursts stripped a portion of Mercury's incompletely condensed protoplanet and transported it to the region between Mars and Jupiter where it fused with in-falling oxidized condensate from the outer regions of the Solar System, forming the parent matter of ordinary chondrite meteorites, the main-Belt asteroids, and veneer for the inner planets, especially Mars. With its massive gas/ice shell

    Despite important human and financial resources and considerable accumulation of scientific publications, patents, and clinical trials, cancer research has been slow in achieving a therapeutic revolution similar to the one that occurred in the last century for infectious diseases. It has been proposed that science proceeds not only by accumulating data but also through paradigm shifts. Here, we propose to use the concept of 'paradigm shift' as a method of investigation when dominant paradigms fail to achieve their promises. The first step in using the 'paradigm shift' method in cancer research requires identifying its founding paradigms. In this review, two of these founding paradigms will be discussed: (i) the reification of cancer as a tumour mass and (ii) the translation of the concepts issued from infectious disease in cancer research. We show how these founding paradigms can generate biases that lead to over-diagnosis and over-treatment and also hamper the development of curative cancer therapies. We apply the 'paradigm shift' method to produce perspective reversals consistent with current experimental evidence. The 'paradigm shift' method enlightens the existence of a tumour physiologic-prophylactic-pathologic continuum. It integrates the target/antitarget concept and that cancer is also an extracellular disease. The 'paradigm shift' method has immediate implications for cancer prevention and therapy. It could be a general method of investigation for other diseases awaiting therapy.

  12. Tourism development and the degrowth paradigm

    Directory of Open Access Journals (Sweden)

    Andriotis Konstantinos

    2014-01-01

    Full Text Available This paper aims to look at alternatives to the classic models of development by exploring the paradigm of degrowth in a tourism context. Degrowth touted as an alternative to mainstream paradigms of development, aims to ensure a high quality of life for people in a society where work, production and consumption are reduced. As a weapon to the problems accrued by capitalism, degrowth reorients the current unsustainable and inequitable path through the transition to a smaller economy with less production and consumption. By arguing that natural limits to growth of many destinations have already been surpassed and their carrying capacity levels have been reached, degrowth proposes the abandonment of growth which promotes nothing other than a quest for profits on part of the owners of capital and results in disastrous implications for the environment and the humanity. As a philosophical concept and movement, degrowth is revolutionary and anticapitalist directed to sustainable change which results from an interest in locality and place, small and medium-sized enterprises, employment generation and reduction in working hours, ecology and quality of life, decommodification of tourism activity, carbon reduction in transport, changed pattern of production and consumption, and high priority in the travel experience.

    2013-01-01

    Public-display systems are still far from being a medium for meeting people's diverse communication goals. Moving toward open displays will require publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully understand and control the publication process. The metaphors of pins and posters have inspired two complementary paradigms for public displays. Researchers implemented these paradigms in the Instant Places system, which they deployed on 10 displays in diverse urban locations for six months. They collected user and system data regarding the users' practices. The findings improve the understanding of what might drive user-generated content in networks of urban displays. Such knowledge can inform the design of tools and procedures for situated publication in public displays.

    International Nuclear Information System (INIS)

    Ashtekar, Abhay; Bojowald, Martin

    2005-01-01

    A paradigm describing black hole evaporation in non-perturbative quantum gravity is developed by combining two sets of detailed results: (i) resolution of the Schwarzschild singularity using quantum geometry methods and (ii) time evolution of black holes in the trapping and dynamical horizon frameworks. Quantum geometry effects introduce a major modification in the traditional spacetime diagram of black hole evaporation, providing a possible mechanism for recovery of information that is classically lost in the process of black hole formation. The paradigm is developed directly in the Lorentzian regime and necessary conditions for its viability are discussed. If these conditions are met, much of the tension between expectations based on spacetime geometry and structure of quantum theory would be resolved

  16. Three Paradigms of Social Assistance

    Directory of Open Access Journals (Sweden)

    Pierre-Marc Daigneault

    2014-11-01

    Full Text Available “Ideas,” which are defined as the normative and cognitive beliefs of actors, are fundamental to a full understanding of the welfare state and, in particular, of social assistance. However, policy ideas have been neglected in most typologies of social assistance regimes. Based on a selective review of the literature, this article proposes a brief but systematic analysis of policy paradigms in the field of social assistance. Three ideal types that emphasize the ideational dimension of social assistance are analyzed, namely, the entitlement, workfare, and activation paradigms. The value of the typology lies in its utility for characterizing the ideational orientation of social assistance regimes. Specifically, the typology provides a yardstick for measuring the ideas of policy actors with respect to social assistance and can facilitate the conduct of case studies, comparative research, and causal analyses on this policy sector.

  2. About hypotheses and paradigms: exploring the Discreetness-Chance Paradigm.

    Science.gov (United States)

    Kaellis, Eugene

    2006-01-01

    Hypotheses generally conform to paradigms which, over time, change, usually tardily, after they have become increasingly difficult to sustain under the impact of non-conforming evidence and alternative hypotheses, but more important, when they no longer are comfortably ensconced in the surrounding social-economic-political-cultural milieu. It is asserted that this milieu is the most important factor in shaping scientific theorizing. Some examples are cited: the rejection of the evidence that the world orbits around the sun (suspected by Pythagoras) in favor of centuries-long firm adherence to the Ptolemaic geocentric system; the early acceptance of Natural Selection in spite of its tautological essence and only conjectural supporting evidence, because it justified contemporaneous social-political ideologies as typified by, e.g., Spencer and Malthus. Economic, social, and cultural factors are cited as providing the ground, i.e., ideational substrate, for what is cited as the Discreetness-Chance Paradigm (DCP), that has increasingly dominated physics, biology, and medicine for over a century and which invokes small, discrete packets of energy/matter (quanta, genes, microorganisms, aberrant cells) functioning within an environment of statistical, not determined, causality. There is speculation on a possible paradigmatic shift from the DCP, which has fostered the proliferation, parallel with ("splitting") taxonomy, of alleged individual disease entities, their diagnoses, and, when available, their specific remedies, something particularly prominent in, e.g., psychiatry's Diagnostic and Statistical Manual, a codified compendium of alleged mental and behavioral disorders, but evident in any textbook of diagnosis and treatment of physical ailments. This presumed paradigm shift may be reflected in Western medicine, presently increasingly empirical and atomized, towards a growing acceptance of a more generalized, subject-oriented, approach to health and disease, a non

    1995-01-05

    This paper reviews the current status from the standpoint of chemical engineers facing the coming of the 21st century, and surveys the paradigm for new scientific technologies. The criticism is mixed with unique opinions everywhere, such as `departure of students from scientific and engineering faculties is none other than the result of a market principle`, `national burden of trillions of yens should not be spent only under a justice of advancement of the science`, and `the global civilization itself has no other way but to change from the conventional expansive development type of the western country style to the internal development type of the oriental country style`. Values that define the paradigm for new scientific technologies may include such keywords as saturation in technology, baseless expansion of research projects, criticism on science, market principle, and centering human being. It should be looked at seriously that profit from research and development should exceed the cast invested therein in the future, and scientific technologies that serve truly the society should be aimed at. These efforts will result in one of the large pillars that support the future in which creation of new functions is aimed at as a result of structuring the new systems. Trying to overcome the environmental problems is one of them.

  5. An engineering paradigm in the biomedical sciences: Knowledge as epistemic tool.

    2017-10-01

    In order to deal with the complexity of biological systems and attempts to generate applicable results, current biomedical sciences are adopting concepts and methods from the engineering sciences. Philosophers of science have interpreted this as the emergence of an engineering paradigm, in particular in systems biology and synthetic biology. This article aims at the articulation of the supposed engineering paradigm by contrast with the physics paradigm that supported the rise of biochemistry and molecular biology. This articulation starts from Kuhn's notion of a disciplinary matrix, which indicates what constitutes a paradigm. It is argued that the core of the physics paradigm is its metaphysical and ontological presuppositions, whereas the core of the engineering paradigm is the epistemic aim of producing useful knowledge for solving problems external to the scientific practice. Therefore, the two paradigms involve distinct notions of knowledge. Whereas the physics paradigm entails a representational notion of knowledge, the engineering paradigm involves the notion of 'knowledge as epistemic tool'. Copyright © 2017 Elsevier Ltd.

  6. The Paradigm of Distributed Creativity

    DEFF Research Database (Denmark)

    Glaveanu, Vlad Petre

    This presentation aims to focus on and develop the notion of distributed creativity from a cultural psychological perspective. It will start by outlining the need for a cultural psychological paradigm of creative expression and argue that this perspective is primarily concerned with what can...... be called ‘distributed creativity’. Drawing on related literature on distributed cognition (Hutchins, 2000), I will consider here the three inter-related ways in which creative action is distributed: across people, across people and objects, and across time. This particular understanding of creativity...

  7. Psychiatry beyond the current paradigm.

    2012-12-01

    A series of editorials in this Journal have argued that psychiatry is in the midst of a crisis. The various solutions proposed would all involve a strengthening of psychiatry\\'s identity as essentially \\'applied neuroscience\\'. Although not discounting the importance of the brain sciences and psychopharmacology, we argue that psychiatry needs to move beyond the dominance of the current, technological paradigm. This would be more in keeping with the evidence about how positive outcomes are achieved and could also serve to foster more meaningful collaboration with the growing service user movement.

    2018-01-01

    In this paper, we review one of the oldest paradigms used in animal cognition: the detour paradigm. The paradigm presents the subject with a situation where a direct route to the goal is blocked and a detour must be made to reach it. Often being an ecologically valid and a versatile tool, the detour paradigm has been used to study diverse cognitive skills like insight, social learning, inhibitory control and route planning. Due to the relative ease of administrating detour tasks, the paradigm has lately been used in large-scale comparative studies in order to investigate the evolution of inhibitory control. Here we review the detour paradigm and some of its cognitive requirements, we identify various ecological and contextual factors that might affect detour performance, we also discuss developmental and neurological underpinnings of detour behaviors, and we suggest some methodological approaches to make species comparisons more robust.

  10. Models for predicting the inflectional paradigm of Croatian words

    Directory of Open Access Journals (Sweden)

    Jan Šnajder

    2013-12-01

    Full Text Available Morphological analysis is a prerequisite for many natural language processing tasks. For inflectionally rich languages such as Croatian, morphological analysis typically relies on a morphological lexicon, which lists the lemmas and their paradigms. However, a real-life morphological analyzer must also be able to handle properly the out-of-vocabulary words. We address the task of predicting the correct inflectional paradigm of unknown Croatian words. We frame this as a supervised machine learning problem: we train a classifier to predict whether a candidate lemma-paradigm pair is correct based on a number of string- and corpus-based features. The candidate lemma-paradigm pairs are generated using a handcrafted morphology grammar. Our aim is to examine the machine learning aspect of the problem: we test a comprehensive set of features and evaluate the classification accuracy using different feature subsets. We show that satisfactory classification accuracy (92% can be achieved with SVM using a combination of string- and corpus-based features. On a per word basis, the F1-score is 53% and accuracy is 70%, which outperforms a frequency-based baseline by a wide margin. We discuss a number of possible directions for future research.

  11. A movement ecology paradigm for unifying organismal movement research.

    Movement of individual organisms is fundamental to life, quilting our planet in a rich tapestry of phenomena with diverse implications for ecosystems and humans. Movement research is both plentiful and insightful, and recent methodological advances facilitate obtaining a detailed view of individual movement. Yet, we lack a general unifying paradigm, derived from first principles, which can place movement studies within a common context and advance the development of a mature scientific discipline. This introductory article to the Movement Ecology Special Feature proposes a paradigm that integrates conceptual, theoretical, methodological, and empirical frameworks for studying movement of all organisms, from microbes to trees to elephants. We introduce a conceptual framework depicting the interplay among four basic mechanistic components of organismal movement: the internal state (why move?), motion (how to move?), and navigation (when and where to move?) capacities of the individual and the external factors affecting movement. We demonstrate how the proposed framework aids the study of various taxa and movement types; promotes the formulation of hypotheses about movement; and complements existing biomechanical, cognitive, random, and optimality paradigms of movement. The proposed framework integrates eclectic research on movement into a structured paradigm and aims at providing a basis for hypothesis generation and a vehicle facilitating the understanding of the causes, mechanisms, and spatiotemporal patterns of movement and their role in various ecological and evolutionary processes. "Now we must consider in general the common reason for moving with any movement whatever." (Aristotle, De Motu Animalium, 4th century B.C.).

  13. The Oral Paradigm and Snapchat

    Directory of Open Access Journals (Sweden)

    Oren Soffer

    2016-09-01

    Full Text Available In this short essay, I argue that the ephemeral nature of emerging instant-messaging applications, such as Snapchat, applies an oral paradigm. While online discourse of computer-mediated communication shares many qualities with oral communication, the case of ephemeral applications is unique, as the oral features are already integrated in the application technology design and as orality is often implemented on highly visual products. Snapchat applies technology that fades visual contents as if they were spoken words fading in the air after utterance. Moreover, Snapchat’s promise to delete all messages from its database after they are viewed echoes a key characteristic of primary oral culture: that is, the inability (and in our case, the obligation not to store knowledge. In this, Snapchat demonstrates counter-logic to the contemporary grammar of new media, which is based on information aggregation.

  14. Toward a New Energy Paradigm

    2006-01-01

    More than 50% of the developing world does not have access to electricity. It is our belief that it is as much a problem of distribution as of production. The traditional approach of power distribution through a national grid system is remarkably slow. Alternate methods are not sought because of an implicit assumption that it is an area that would necessarily involve large infra-structural undertaking. However, the traditional distribution paradigm can be challenged by new developments in fuel cell technology that can open up the possibility of involvement of small private initiatives in the distribution of power in remote areas where grid penetration has not taken place. This would require distribution re-engineering in an innovative and practical way based on advancement in new technology (fuel cells in our case). Our business approach would require a shift in focus away from production to distribution in addressing the issue. (authors)

    Many shieldings have been designed under the criteria of 'Maximum dose rates of project'. It has created the paradigm of those 'low dose rates', for the one which not few specialists would consider unacceptable levels of dose rate superior to the units of μSv.h -1 , independently of the exposure times. At the present time numerous shieldings are being designed considering dose restrictions in real times of exposure. After these new shieldings, the dose rates could be notably superior to those after traditional shieldings, without it implies inadequate designs or constructive errors. In the work significant differences in levels of dose rates and thickness of shieldings estimated by both methods for some typical facilities. It was concluded that the use of real times of exposure is more adequate for the optimization of the Radiological Protection, although this method demands bigger care in its application. (Author)

    Many radiation shielding barriers in Cuba have been designed according to the criterion of Maxi-mum Projected Dose Rates. This fact has created the paradigm of low dose rates. Because of this, dose rate levels greater than units of Sv.h-1 would be considered unacceptable by many specialists, regardless of the real exposure times. Nowadays many shielding barriers are being designed using dose constraints in real exposure times. Behind the new barriers, dose rates could be notably greater than those behind the traditional ones, and it does not imply inadequate designs or constructive errors. In this work were obtained significant differences in dose rate levels and shield-ing thicknesses calculated by both methods for some typical installations. The work concludes that real exposure time approach is more adequate in order to optimise Radiation Protection, although this method should be carefully applied

  5. Understanding paradigms used for nursing research.

    Weaver, Kathryn; Olson, Joanne K

    2006-02-01

    The aims of this paper are to add clarity to the discussion about paradigms for nursing research and to consider integrative strategies for the development of nursing knowledge. Paradigms are sets of beliefs and practices, shared by communities of researchers, which regulate inquiry within disciplines. The various paradigms are characterized by ontological, epistemological and methodological differences in their approaches to conceptualizing and conducting research, and in their contribution towards disciplinary knowledge construction. Researchers may consider these differences so vast that one paradigm is incommensurable with another. Alternatively, researchers may ignore these differences and either unknowingly combine paradigms inappropriately or neglect to conduct needed research. To accomplish the task of developing nursing knowledge for use in practice, there is a need for a critical, integrated understanding of the paradigms used for nursing inquiry. We describe the evolution and influence of positivist, postpositivist, interpretive and critical theory research paradigms. Using integrative review, we compare and contrast the paradigms in terms of their philosophical underpinnings and scientific contribution. A pragmatic approach to theory development through synthesis of cumulative knowledge relevant to nursing practice is suggested. This requires that inquiry start with assessment of existing knowledge from disparate studies to identify key substantive content and gaps. Knowledge development in under-researched areas could be accomplished through integrative strategies that preserve theoretical integrity and strengthen research approaches associated with various philosophical perspectives. These strategies may include parallel studies within the same substantive domain using different paradigms; theoretical triangulation to combine findings from paradigmatically diverse studies; integrative reviews; and mixed method studies. Nurse scholars are urged to

    International Nuclear Information System (INIS)

    Thorne, K.S.; Price, R.H.; Macdonald, D.A.

    1986-01-01

    The physics of black holes is explored in terms of a membrane paradigm which treats the event horizon as a two-dimensional membrane embedded in three-dimensional space. A 3+1 formalism is used to split Schwarzschild space-time and the laws of physics outside a nonrotating hole, which permits treatment of the atmosphere in terms of the physical properties of thin slices. The model is applied to perturbed slowly or rapidly rotating and nonrotating holes, and to quantify the electric and magnetic fields and eddy currents passing through a membrane surface which represents a stretched horizon. Features of tidal gravitational fields in the vicinity of the horizon, quasars and active galalctic nuclei, the alignment of jets perpendicular to accretion disks, and the effects of black holes at the center of ellipsoidal star clusters are investigated. Attention is also given to a black hole in a binary system and the interactions of black holes with matter that is either near or very far from the event horizon. Finally, a statistical mechanics treatment is used to derive a second law of thermodynamics for a perfectly thermal atmosphere of a black hole

    According to the paradigm of the Self-Organized Criticality (SOC), the anomalous transport in tokamaks is caused by fast transient processes - avalanches. One of the manifestations of these phenomena should be 1/f decay of electrostatic fluctuations power spectra in a certain frequency range. In this paper, the frequency spectra of floating potential, density and fluctuation-induced flux, measured by poloidal and radial arrays of Langmuir probes on the CASTOR tokamak, are presented. The floating potential and the fluctuation-induced flux decay from 30 kHz up to 100 kHz as f -1 . The plasma density decays as f -1 in a more narrow band, 20 to 40 kHz. The possible limitation of SOC behavior for frequencies higher than 100 kHz due to intermittency is stressed. For this reason the Probability Distribution Functions (PDFs) of floating potential fluctuations were computed at different time scales using wavelet transform. A clear departure of the computed PDFs from Gaussianity, which is a classical signature of intermittency, is observed at time scales under 10 μs (100 kHz). (author)

  8. MDMA and the "ecstasy paradigm".

    Science.gov (United States)

    Cole, Jon C

    2014-01-01

    For nearly 30 years, there has been a steady flow of research papers highlighting the dangers of MDMA and the implications for ecstasy users. After such a long time, it would be reasonable to expect that these dangers would be obvious due to the large number of ecstasy users. The available evidence does not indicate that there are millions of ecstasy users experiencing any problems linked to their ecstasy use. The "precautionary principle" suggests that, in the absence of knowing for certain, "experts" should argue that MDMA be avoided. However, this may have been taken too far, as the dire warnings do not seem to be reducing with the lack of epidemiological evidence of clinically relevant problems. The "ecstasy paradigm" is one way of articulating this situation, in that the needs of research funders and publication bias lead to a specific set of subcultural norms around what information is acceptable in the public domain. By digging a little deeper, it is easy to find problems with the evidence base that informs the public debate around MDMA. The key question is whether it is acceptable to maintain this status quo given the therapeutic potential of MDMA.

  9. Cancer: shift of the paradigm.

    Lichtenstein, Anatoly V

    2008-12-01

    Cancer is usually considered to be a by-product of design limitations of a multicellular organism and its intrinsic fallibility. However, recent data prompt a revision of some established notions about carcinogenesis and form a new paradigm of carcinogenesis as a highly conserved biological phenomenon - a programmed death of an organism. This altruistic program, which is unleashed when mutagenesis surpasses a certain critical threshold, gives a population the important benefit acting as a guardian of the gene pool against the spread of certain mutant genes. A growing body of evidence supports this point of view: (i) epigenetic changes leading to cancer arise early, simultaneously in many cells and look like deterministic regulation; (ii) concept of cancer stem cell suggests a view of carcinogenesis not as vague transformation but as well known differentiation; (iii) tumor/host relations usually perceived as antagonistic are, in reality, synergistic; (iv) death of an individual from cancer is predetermined and results apparently from a specific activity (killer function) of cancer cell and (v) evolutionary conservation indicates that cancer comes with a general advantage that explains its evolutionary success. A holistic approach to carcinogenesis suggests new avenues of research and new therapeutic strategy.

  10. The Predictive Processing Paradigm Has Roots in Kant.

    Swanson, Link R

    2016-01-01

    Predictive processing (PP) is a paradigm in computational and cognitive neuroscience that has recently attracted significant attention across domains, including psychology, robotics, artificial intelligence and philosophy. It is often regarded as a fresh and possibly revolutionary paradigm shift, yet a handful of authors have remarked that aspects of PP seem reminiscent of the work of 18th century philosopher Immanuel Kant. To date there have not been any substantive discussions of how exactly PP links back to Kant. In this article, I argue that several core aspects of PP were anticipated by Kant (1996/1787) in his works on perception and cognition. Themes from Kant active in PP include: (1) the emphasis on "top-down" generation of percepts; (2) the role of "hyperpriors"; (3) the general function of "generative models"; (4) the process of "analysis-by-synthesis"; and (5) the crucial role of imagination in perception. In addition to these, I also point out that PP echoes Kant's general project in that it aims to explain how minds track causal structure in the world using only sensory data, and that it uses a reverse-engineer or "top-down" method of analysis. I then locate a possible source of Kant's influence on PP by tracing the paradigm back to Hermann von Helmholtz, who saw himself as providing a scientific implementation of Kant's conclusions. I conclude by arguing that PP should not be regarded as a new paradigm, but is more appropriately understood as the latest incarnation of an approach to perception and cognition initiated by Kant and refined by Helmholtz.

  12. Electromagnetic servoing-a new tracking paradigm.

    2013-08-01

    Electromagnetic (EM) tracking is highly relevant for many computer assisted interventions. This is in particular due to the fact that the scientific community has not yet developed a general solution for tracking of flexible instruments within the human body. Electromagnetic tracking solutions are highly attractive for minimally invasive procedures, since they do not require line of sight. However, a major problem with EM tracking solutions is that they do not provide uniform accuracy throughout the tracking volume and the desired, highest accuracy is often only achieved close to the center of tracking volume. In this paper, we present a solution to the tracking problem, by mounting an EM field generator onto a robot arm. Proposing a new tracking paradigm, we take advantage of the electromagnetic tracking to detect the sensor within a specific sub-volume, with known and optimal accuracy. We then use the more accurate and robust robot positioning for obtaining uniform accuracy throughout the tracking volume. Such an EM servoing methodology guarantees optimal and uniform accuracy, by allowing us to always keep the tracked sensor close to the center of the tracking volume. In this paper, both dynamic accuracy and accuracy distribution within the tracking volume are evaluated using optical tracking as ground truth. In repeated evaluations, the proposed method was able to reduce the overall error from 6.64±7.86 mm to a significantly improved accuracy of 3.83±6.43 mm. In addition, the combined system provides a larger tracking volume, which is only limited by the reach of the robot and not the much smaller tracking volume defined by the magnetic field generator.

    2015-06-01

    We describe Ostracism Online, a novel, social media-based ostracism paradigm designed to (1) keep social interaction experimentally controlled, (2) provide researchers with the flexibility to manipulate the properties of the social situation to fit their research purposes, (3) be suitable for online data collection, (4) be convenient for studying subsequent within-group behavior, and (5) be ecologically valid. After collecting data online, we compared the Ostracism Online paradigm with the Cyberball paradigm (Williams & Jarvis Behavior Research Methods, 38, 174-180, 2006) on need-threat and mood questionnaire scores (van Beest & Williams Journal of Personality and Social Psychology 91, 918-928, 2006). We also examined whether ostracized targets of either paradigm would be more likely to conform to their group members than if they had been included. Using a Bayesian analysis of variance to examine the individual effects of the different paradigms and to compare these effects across paradigms, we found analogous effects on need-threat and mood. Perhaps because we examined conformity to the ostracizers (rather than neutral sources), neither paradigm showed effects of ostracism on conformity. We conclude that Ostracism Online is a cost-effective, easy to use, and ecologically valid research tool for studying the psychological and behavioral effects of ostracism.

  14. Evolution of the radiological protection paradigms

    Sordi, Gian Maria A.A.

    2009-01-01

    We consider as initial radiological protection paradigms those in vigour after the release of the atomic energy for pacific usages in 1955. In that occasion, only one paradigm was introduced, presently named dose limitation system. After arguing about the basis that raised the paradigm, we introduced the guidance, that is, the measurements to be implemented to comply with the paradigm. In that occasion, they were two, i.e., the radiation dose monitoring and the workplace classification. Afterwards, the reasons that caused the radiological protection paradigms changes in force until 1995 are discussed. The initial paradigm was modified introducing the justification and the optimization principles, adding that the radiological protection should be economical and effective. The guidance also increased to four: personal monitoring, workplace classification, reference level and workers classification. Afterwards, we give the main justifications for the present paradigms that besides the formers were added the dose constraints, the potential exposure and the annual risk limits. Due to these modifications, the workers classifications were eliminated from the guidance, but the potential exposure and the search for the dose constraints were added. Eventually, we discuss the tendencies for the next future and the main changes introduced by the ICRP in the Publication 103, 2007. (author)

  15. The Cognitive Paradigm Ontology: Design and Application

    Science.gov (United States)

    Laird, Angela R.

    2013-01-01

    We present the basic structure of the Cognitive Paradigm Ontology (CogPO) for human behavioral experiments. While the experimental psychology and cognitive neuroscience literature may refer to certain behavioral tasks by name (e.g., the Stroop paradigm or the Sternberg paradigm) or by function (a working memory task, a visual attention task), these paradigms can vary tremendously in the stimuli that are presented to the subject, the response expected from the subject, and the instructions given to the subject. Drawing from the taxonomy developed and used by the BrainMap project (www.brainmap.org) for almost two decades to describe key components of published functional imaging results, we have developed an ontology capable of representing certain characteristics of the cognitive paradigms used in the fMRI and PET literature. The Cognitive Paradigm Ontology is being developed to be compliant with the Basic Formal Ontology (BFO), and to harmonize where possible with larger ontologies such as RadLex, NeuroLex, or the Ontology of Biomedical Investigations (OBI). The key components of CogPO include the representation of experimental conditions focused on the stimuli presented, the instructions given, and the responses requested. The use of alternate and even competitive terminologies can often impede scientific discoveries. Categorization of paradigms according to stimulus, response, and instruction has been shown to allow advanced data retrieval techniques by searching for similarities and contrasts across multiple paradigm levels. The goal of CogPO is to develop, evaluate, and distribute a domain ontology of cognitive paradigms for application and use in the functional neuroimaging community. PMID:21643732

  16. PARADIGM OF EDUCATION FOR THE INFORMATION SOCIETY

    Directory of Open Access Journals (Sweden)

    Yuriy M. Bogachkov

    2015-10-01

    Full Text Available Considering total crisis in education in Informational Age, we suggest that to overcome the crisis, it is necessary to promote pedagogical science up from "pre-paradigm stage” to the "paradigm stage". For this purpose it is necessary to separate the "educational science" from "education." “Educational paradigm” in such study will be the subject of the science. The key concepts for the "pedagogical paradigm" should be the concepts of "educational practice", "class of problems" and "educational text". We offer some axioms around these concepts.

    What would it take for a degrowth paradigm shift to take place? Drawing on contemporary critical political economy scholarship, this article identifies four prerequisites for socio-economic paradigm shifts: deep crisis, an alternative political project, a comprehensive coalition of social forces...... currently facing humanity. On the other hand, the prospects for a degrowth paradigm shift remain bleak: unlike political projects that became hegemonic in the past, degrowth has neither support from a comprehensive coalition of social forces nor any consent to its agenda among the broader population....

    1994-10-01

    This paper addresses some of the emerging software paradigms that may be used in developing safety-critical software applications. Paradigms considered in this paper include knowledge-based systems, neural networks, genetic algorithms, and fuzzy systems. It presents one view of the software verification and validation activities that should be associated with each paradigm. The paper begins with a discussion of the historical evolution of software verification and validation. Next, a comparison is made between the verification and validation processes used for conventional and emerging software systems. Several verification and validation issues for the emerging paradigms are discussed and some specific research topics are identified. This work is relevant for monitoring and control at nuclear power plants

    Until recently, the dominant philosophy of science was that due to Karl Popper, with its doctrine that the proper task of science was the formulation of hypotheses followed by attempts at refuting them. In spite of the close analogy with significance testing, these ideas do not fit well with the practice of medical statistics. The same can be said of the later philosophy of Thomas Kuhn, who maintains that science proceeds by way of revolutionary upheavals separated by periods of relatively pedestrian research which are governed by what Kuhn refers to as paradigms. Through there have been paradigm shifts in the history of statistics, a degree of continuity can also be discerned. A current paradigm shift is embodied in the spread of Bayesian ideas. It may be that a future paradigm will emphasise the pragmatic approach to statistics that is associated with the name of Daniel Schwartz.

  3. A Positive Generation Effect on Memory for Auditory Context.

    2017-06-01

    Self-generation of information during memory encoding has large positive effects on subsequent memory for items, but mixed effects on memory for contextual information associated with items. A processing account of generation effects on context memory (Mulligan in Journal of Experimental Psychology: Learning, Memory, and Cognition, 30(4), 838-855, 2004; Mulligan, Lozito, & Rosner in Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(4), 836-846, 2006) proposes that these effects depend on whether the generation task causes any shift in processing of the type of context features for which memory is being tested. Mulligan and colleagues have used this account to predict various negative effects of generation on context memory, but the account also predicts positive generation effects under certain circumstances. The present experiment provided a critical test of the processing account by examining how generation affected memory for auditory rather than visual context. Based on the processing account, we predicted that generation of rhyme words should enhance processing of auditory information associated with the words (i.e., voice gender), whereas generation of antonym words should have no effect. These predictions were confirmed, providing support to the processing account.

    We used independent component analysis (ICA) of high-density EEG recordings coupled with single dipole fitting to identify the dominant brain regions active during the MMN in two different versions of a passive oddball paradigm: a simple, monotic, frequency-deviant paradigm and a more complex, dichotic, frequency-deviant paradigm with deviants occurring in either ear alone or in both ears at the same time. In both paradigms we found brain regional sources in the temporal and frontal cortices active during the MMN period, consistent with some previous studies. In the simpler paradigm, the scalp-potential variance during the earlier (70-120 ms) MMN was mostly accounted for by a wide array of temporal, frontal, and parietal sources. In the more complex paradigm, however, a generator in the prefrontal cortex accounted for a substantial amount of the variance of the scalp potential during the somewhat later MMN period (120-200 ms). These findings are consistent with a more nuanced view of the MMN and its generators than has been held in the past. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2015-01-01

    Highlights: • We propose a novel concept of hydropower development technological paradigm. • We create a data analysis system to visualize the keyword foci. • Future trajectories include hybrid power systems and resources from seawater. • The HDTP consists of a three-stage evolution and a policy framework. • The HDTP provides a how-to-do solution for the soft path. - Abstract: Hydropower has long been considered the backbone of the power generation sector in low-carbon and sustainable energy systems. Yet, as reliance on hydropower has been generally declining, the world is awakening to the need to fundamentally rethink the way hydropower is developed and managed. The paper proposes a systematic methodology to research the development trends and find a more sustainable hydropower path. Literature mining using the data analysis system and the technological paradigm theory were adopted to conduct the research. The keyword visualization results were found to meet the laws for the three phases of the technological paradigm. Specific key areas, such as small hydropower plants, hybrid power systems, and hydropower from seawater were identified as past, present and near future trajectories. To further accelerate hydropower development, specific subsidies and incentives need to be provided in areas such as capital costs and technological support. The study paves the way for a soft path solution which complements the hard path in hydropower field

    After a brief discussion of the EPR paradox, Bell's inequality, and Aspect's experiment, arguments will be presented in favor of the following statements: ``As it stands, Quantum mechanics is incomplete. There is further hidden structure, which would involve variables. No influence can move faster than light. The wave function is one whole thing and any change in its structure instantly influences its outcomes. Bell's theorem has not been applied correctly. There is a better paradigm.'' The said paradigm will be presented.

  9. Project management: a new service delivery paradigm

    2007-07-01

    Full Text Available In line with international trends in governance, the South African Government’s initial focus on the development of policy frameworks, structures and systems in order to give effect to the values and principles of the Constitution, shifted to the most critical issue, namely service delivery. The Government became increasingly aware that a significant expansion in the scope and quality of service provision was not possible with traditional delivery settings and approaches. There is growing evidence that there is a need for a significant departure from conventional approaches and that a leap into a new service delivery paradigm is necessary. Increasingly this new paradigm highlights the need to further develop the government’s project management skills and applications with a view to achieving improved delivery capability. In this article the focus will be placed on the changing service delivery paradigm – from an “old” traditional model through the transition to a “new” paradigm. This paradigm is shaped by international and national trends and events in government. The contribution and advantages of project management applications for effective governance are highlighted and the article concludes with an explanation of project management organisational arrangements necessary to support the new paradigm.

    2015-01-01

    We develop here a multi-agent model of the creation of knowledge (scientific progress or technological evolution) within a community of researchers devoted to such endeavors. In the proposed model, agents learn in a physical-technological landscape, and weight is attached to both individual search and social influence. We find that the combination of these two forces together with random experimentation can account for both i) marginal change, that is, periods of normal science or refinements on the performance of a given technology (and in which the community stays in the neighborhood of the current paradigm); and ii) radical change, which takes the form of scientific paradigm shifts (or discontinuities in the structure of performance of a technology) that is observed as a swift migration of the knowledge community towards the new and superior paradigm. The efficiency of the search process is heavily dependent on the weight that agents posit on social influence. The occurrence of a paradigm shift becomes more likely when each member of the community attaches a small but positive weight to the experience of his/her peers. For this parameter region, nevertheless, a conservative force is exerted by the representatives of the current paradigm. However, social influence is not strong enough to seriously hamper individual discovery, and can act so as to empower successful individual pioneers who have conquered the new and superior paradigm.

  12. Choice-Induced Preference Change in the Free-Choice Paradigm: A Critical Methodological Review

    2013-02-01

    Full Text Available Choices not only reflect our preference, but they also affect our behavior. The phenomenon of choice-induced preference change has been of interest to cognitive dissonance researchers in social psychology, and more recently, it has attracted the attention of researchers in economics and neuroscience. Preference modulation after the mere act of making a choice has been repeatedly demonstrated over the last 50 years by an experimental paradigm called the free-choice paradigm. However, in 2010, Chen and Risen pointed out a serious methodological flaw in this paradigm, arguing that evidence for choice-induced preference change is still insufficient. Despite the flaw, studies using the traditional free-choice paradigm continue to be published without addressing the criticism. Here, aiming to draw more attention to this issue, we briefly explain the methodological problem, and then describe simple simulation studies that illustrate how the free-choice paradigm produces a systematic pattern of preference change consistent with cognitive dissonance, even without any change in true preference. Our stimulation also shows how a different level of noise in each phase of the free-choice paradigm independently contributes to the magnitude of artificial preference change. Furthermore, we review ways of addressing the critique and provide a meta-analysis to show the effect size of choice-induced preference change after addressing the critique. Finally, we review and discuss, based on the results of the stimulation studies, how the criticism affects our interpretation of past findings generated from the free-choice paradigm. We conclude that the use of the conventional free-choice paradigm should be avoided in future research and the validity of past findings from studies using this paradigm should be empirically re-established.

  13. Local seafood: rethinking the direct marketing paradigm

    Directory of Open Access Journals (Sweden)

    Joshua S. Stoll

    2015-06-01

    Full Text Available Faced with strict regulations, rising operational costs, depleted stocks, and competition from less expensive foreign imports, many fishers are pursuing new ways to market and sell their catch. Direct marketing arrangements can increase the ex-vessel value of seafood and profitability of operations for fishers by circumventing dominant wholesale chains of custody and capturing the premium that customers are willing to pay for local seafood. Our analysis goes beyond a paradigm that understands direct marketing arrangements as solely economic tools to consider how these emerging business configurations create a set of conditions that can result in increased bonding and bridging capital among fishers by incentivizing cooperation, communication, and information production and organization. To build our case, we report on the economic value being generated for fishers in a cooperatively owned and operated direct marketing arrangement in eastern North Carolina. Over the course of 2 years, fishers participating in the Walking Fish community-supported fishery received 33% more revenue for their catch compared to the average monthly ex-vessel price of finfish and shellfish landed in the surrounding region, and an additional 14% to 18% more per dollar by way of year-end profit sharing. We argue that these economic benefits create an incentive to participate, resulting in cooperation among fishers and increased communication skills that foster bonding and bridging capital that put fishers in a position to identify and respond to challenges that threaten the social-ecological resilience of the systems within which they operate. We suggest that "institutional starters" like these can play a critical role in increasing the resilience of social-ecological systems, including fisheries.

    2009-04-01

    Functional magnetic resonance imaging (fMRI) is frequently used to localize language areas in a non-invasive manner. Various paradigms for presurgical localization of language areas have been developed, but a systematic quantitative evaluation of the efficiency of those paradigms has not been performed. In the present study, the authors analyzed different language paradigms to see which paradigm is most efficient in localizing frontal language areas. Five men and five women with no neurological deficits participated (mean age, 24 years) in this study. All volunteers were right-handed. Each subject performed 4 tasks, including fixation (Fix), sentence reading (SR), pseudoword reading (PR), and word generation (WG). Fixation and pseudoword reading were used as contrasts. The functional area was defined as the area(s) with a t-value of more than 3.92 in fMRI with different tasks. To apply an anatomical constraint, we used a brain atlas mapping system, which is available in AFNI, to define the anatomical frontal language area. The numbers of voxels in overlapped area between anatomical and functional area were individually counted in the frontal expressive language area. Of the various combinations, the word generation task was most effective in delineating the frontal expressive language area when fixation was used as a contrast (plocalizing Broca's area was 81% and specificity was 70%. Word generation versus fixation could effectively and reliably delineate the frontal language area. A customized effective paradigm should be analyzed in order to evaluate various language functions.

The main purpose of this study is to reveal the result of this integration. Methods used in this article include analysis and comparison of "ecological" paradigms on selected parameters (the nature of international relations, actors, targets, tools, processes. Results of research show that the beginning of the XXI century is distinguished by the development of new types of political concepts that explain interaction of elements in modern international relations in the area of environmental protection. The reason of these changes lies in the phenomena of environmentalism integration into Three paradigms of international relations. However, we cannot say that any of the examined paradigms accumulated all features of environmentalism without their modification. Better to say, it's rather similar to adaptation of environmental ideas. Therefore, to understand modern international relations processes, it is necessary to take into account their environmental element. Purchase on Elibrary.ru > Buy nowDOI: http://dx.doi.org/10.12731/2070-7568-2014-3-4

    Kreibig, Sylvia D.; Gross, James J.

    2017-01-01

    In this review, we examine the paradigms and measures available for experimentally studying mixed emotions in the laboratory. For eliciting mixed emotions, we describe a mixed emotions film library that allows for the repeated elicitation of a specific homogeneous mixed emotional state and appropriately matched pure positive, pure negative, and neutral emotional states. For assessing mixed emotions, we consider subjective and objective measures that fall into univariate, bivariate, and multivariate measurement categories. As paradigms and measures for objectively studying mixed emotions are still in their early stages, we conclude by outlining future directions that focus on the reliability, temporal dynamics, and response coherence of mixed emotions paradigms and measures. This research will build a strong foundation for future studies and significantly advance our understanding of mixed emotions. PMID:28804752

  19. Expert systems: an alternative paradigm

    Energy Technology Data Exchange (ETDEWEB)

    Coombs, M.; Alty, J.

    1984-01-01

    There has recently been a significant effort by the AI community to interest industry in the potential of expert systems. However, this has resulted in far fewer substantial applications projects than might be expected. This article argues that this is because human experts are rarely required to perform the role that computer-based experts are programmed to adopt. Instead of being called in to answer well-defined problems, they are more often asked to assist other experts to extend and refine their understanding of a problem area at the junction of their two domains of knowledge. This more properly involves educational rather than problem-solving skills. An alternative approach to expert system design is proposed based upon guided discovery learning. The user is provided with a supportive environment for a particular class of problem, the system predominantly acting as an adviser rather than directing the interaction. The environment includes a database of domain knowledge, a set of procedures for its application to a concrete problem, and an intelligent machine-based adviser to judge the user's effectiveness and advise on strategy. The procedures focus upon the use of user generated explanations both to promote the application of domain knowledge and to expose understanding difficulties. Simple database PROLOG is being used as the subject material for the prototype system which is known as MINDPAD. 30 references.

    2018-05-15

    Future electronics will take on more important roles in people's lives. They need to allow more intimate contact with human beings to enable advanced health monitoring, disease detection, medical therapies, and human-machine interfacing. However, current electronics are rigid, nondegradable and cannot self-repair, while the human body is soft, dynamic, stretchable, biodegradable, and self-healing. Therefore, it is critical to develop a new class of electronic materials that incorporate skinlike properties, including stretchability for conformable integration, minimal discomfort and suppressed invasive reactions; self-healing for long-term durability under harsh mechanical conditions; and biodegradability for reducing environmental impact and obviating the need for secondary device removal for medical implants. These demands have fueled the development of a new generation of electronic materials, primarily composed of polymers and polymer composites with both high electrical performance and skinlike properties, and consequently led to a new paradigm of electronics, termed "skin-inspired electronics". This Account covers recent important advances in skin-inspired electronics, from basic material developments to device components and proof-of-concept demonstrations for integrated bioelectronics applications. To date, stretchability has been the most prominent focus in this field. In contrast to strain-engineering approaches that extrinsically impart stretchability into inorganic electronics, intrinsically stretchable materials provide a direct route to achieve higher mechanical robustness, higher device density, and scalable fabrication. The key is the introduction of strain-dissipation mechanisms into the material design, which has been realized through molecular engineering (e.g., soft molecular segments, dynamic bonds) and physical engineering (e.g., nanoconfinement effect, geometric design). The material design concepts have led to the successful demonstrations of

  1. Paradigms of Interaction Between Culture and Politics

    Directory of Open Access Journals (Sweden)

    Morteza Bahrani

    2012-12-01

    Full Text Available Political thought as a normative knowledge seeks a good society and the means for its realization. Accordingly, every intellectual paradigm introduces us a social and individual situation which is the best. This model, itself requires a dramatic change in the culture and flourishes it. In another words, there is a necessary relationship between the elements of political thought and the culture in every society. This relationship is twofold, so it is impossible to indicate whether which aspect is the first. So every paradigm feeds some special elements into the current culture of society, while there is it feedback. It is important that political thought goes in search of condition for cultural flourishing which is according whit the criteria of good society. This paper focuses on most important paradigm in political thought history and shows the trend in which indicates the relationships between political thought and culture. This trend looks at human beings as "citizen", then "the individual"; and in the modem era, paradigms of "critical modem", "postmodern", and "communitarian" has a key role in prospering the realm of culture.

  3. Increasing Product Confidence-Shifting Paradigms.

    2015-01-01

    Leaders in the pharmaceutical, medical device, and food industries expressed a unilateral concern over product confidence throughout the total product lifecycle, an unsettling fact for these leaders to manage given that their products affect the lives of millions of people each year. Fueled by the heparin incident of intentional adulteration in 2008, initial efforts for increasing product confidence were focused on improving the confidence of incoming materials, with a belief that supplier performance must be the root cause. As in the heparin case, concern over supplier performance extended deep into the supply chain to include suppliers of the suppliers-which is often a blind spot for pharmaceutical, device, and food manufacturers. Resolved to address the perceived lack of supplier performance, these U.S. Food and Drug Administration (FDA)-regulated industries began to adopt the supplier relationship management strategy, developed by the automotive industry, that emphasizes "management" of suppliers for the betterment of the manufacturers. Current product and supplier management strategies, however, have not led to a significant improvement in product confidence. As a result of the enduring concern by industry leaders over the lack of product confidence, Xavier University launched the Integrity of Supply Initiative in 2012 with a team of industry leaders and FDA officials. Through a methodical research approach, data generated by the pharmaceutical, medical device, and food manufacturers surprisingly pointed to themselves as a source of the lack of product confidence, and revealed that manufacturers either unknowingly increase the potential for error or can control/prevent many aspects of product confidence failure. It is only through this paradigm shift that manufacturers can work collaboratively with their suppliers as equal partners, instead of viewing their suppliers as "lesser" entities needing to be controlled. The basis of this shift provides manufacturers

    Petty, Nicola J; Thomson, Oliver P; Stew, Graham

    2012-08-01

    The manual therapy professions have almost exclusively focused on the use of quantitative research to help inform their practices. This paper argues that a greater use of qualitative research will help develop a more robust and comprehensive knowledge base in manual therapy. The types of knowledge used in practice and generated from the two research paradigms are explored. It is hoped that an understanding of the philosophical and theoretical underpinnings of qualitative research may encourage more manual therapists to value and use this approach to help further inform their practice; for some, this may involve a paradigm shift in thinking.

    2013-01-01

    Global palaeoclimate reconstructions have been invaluable to our understanding of the causes and effects of climate change, but single-temperature representations of the oceanic mixed layer for data–model comparisons are outdated, and the time for a paradigm shift in marine palaeoclimate reconstruction is overdue. The new paradigm in marine palaeoclimate reconstruction stems the loss of valuable climate information and instead presents a holistic and nuanced interpretation of multi-dimensional oceanographic processes and responses. A wealth of environmental information is hidden within the US Geological Survey's Pliocene Research,Interpretation and Synoptic Mapping (PRISM) marine palaeoclimate reconstruction, and we introduce here a plan to incorporate all valuable climate data into the next generation of PRISM products. Beyond the global approach and focus, we plan to incorporate regional climate dynamics with emphasis on processes, integrating multiple environmental proxies wherever available in order to better characterize the mixed layer, and developing a finer time slice within the Mid-Piacenzian Age of the Pliocene, complemented by underused proxies that offer snapshots into environmental conditions. The result will be a proxy-rich, temporally nested, process-oriented approach in a digital format - a relational database with geographic information system capabilities comprising a three-dimensional grid representing the surface layer, with a plethora of data in each cell.

  6. The membrane paradigm for black holes

    Price, R.H.; Thorne, K.S.

    1988-01-01

    It is now widely accepted that black holes exist and have an astrophysical role, in particular as the likely power source of quasars. To understand this role with ease, the authors and their colleagues have developed a new paradigm for black holes - a new way to picture, think about and describe them. As far as possible it treats black holes as ordinary astrophysical objects, made of real material. A black hole in this description is a spherical or oblate surface made of a thin, electrically conducting membrane. It was the author's quest to understand the Blandford-Znajek process intuitively that led them to create the membrane paradigm. Their strategy was to translate the general-relativistic mathematics of black holes into the same language of three-dimensional space that is used for magnetized plasmas and to create a new set of black-hole diagrams and pictures to go along with the language. 9 figs

  7. Changing the Dominant Paradigm in Economics

    2015-10-01

    Full Text Available This article addresses the discussion proposed by the World Academy of Art & Science (WAAS about the need to build a new paradigm to confront the challenges of the global society and to move across to a New Society discussing specific problems related to economic globalization and proposing changes. The ways in which economic orthodoxy and heterodoxy analyze the role of the State and the question of sustainability of development and the problems of environmental sustainability depend on their different views or theoretical arguments about the role of the market. The article contrasts the mainstream economics arguments to support the free market context of globalization with Post-Keynesian and Marxist’s skeptical or critical views. Finally, it proposes some strategies to face the critical aspects analyzed making suggestions to move to another dominant economic paradigm.

    2009-01-01

    Population aging is a demographic reality for Brazil. Consequently, in the next years it is expected a progressive increase in seeking health care services in the country by women with complaints related to climacterium. Parallel to it, assistance at this part of woman's life has been going through a paradigm shift which has imposed to health professionals a change of attitude in relation to this stage of woman's life. Today it is acknowledged that the climacterium is influenced by biological, psychosocial and cultural factors, whose knowledge is fundamental for planning a more qualified and humanized care. This article proposes a reflection on the paradigm shifts in assistance at climacterium, highlighting important aspects as multidisciplinarity and interdisciplinarity, so as to serve better this portion of population, and provide it with more integrated and individualized care, bringing together knowledge and sensitivity, and always aiming at a better quality of life.

  9. Inhabiting compassion: A pastoral theological paradigm

    Directory of Open Access Journals (Sweden)

    Phil C. Zylla

    2017-08-01

    Full Text Available Inspired by the vision of care in Vincent van Gogh’s depiction of the parable of the Good Samaritan, this article offers a paradigm for inhabiting compassion. Compassion is understood in this article as a moral emotion that is also a pathocentric virtue. This definition creates a dynamic view of compassion as a desire to alleviate the suffering of others, the capacity to act on behalf of others and a commitment to sustain engagement with the suffering other. To weave this vision of compassion as a habitus rather than a theoretical construct, the article develops three phases of compassion: seeing, companioning and sighing. This framework deepens and augments a pastoral theological paradigm of compassion with the aim of inculcating an inhabited compassion in caregivers and the communities in which they participate.

  10. BMS invariance and the membrane paradigm

    International Nuclear Information System (INIS)

    Penna, Robert F.

    2016-01-01

    The Bondi-van der Burg-Metzner-Sachs (BMS) group is the asymptotic symmetry group of asymptotically flat spacetime. It is infinite dimensional and entails an infinite number of conservation laws. According to the black hole membrane paradigm, null infinity (in asymptotically flat spacetime) and black hole event horizons behave like fluid membranes. The fluid dynamics of the membrane is governed by an infinite set of symmetries and conservation laws. Our main result is to point out that the infinite set of symmetries and conserved charges of the BMS group and the membrane paradigm are the same. This relationship has several consequences. First, it sheds light on the physical interpretation of BMS conservation laws. Second, it generalizes the BMS conservation laws to arbitrary subregions of arbitrary null surfaces. Third, it clarifies the identification of the superrotation subgroup of the BMS group. We briefly comment on the black hole information problem.

  11. Radiation a new paradigm... Societal impacts

    International Nuclear Information System (INIS)

    Sutcliffe, Jill

    2010-01-01

    Latency is associated with the time lag it takes for the health effects resulting from exposure to ionising radiation to show up. However, the term latency can also be applied to the time it takes for a policy to be implemented. This length of time has been suggested as broadly 40-year process. Given that radioactivity was identified and named in 1896, three paradigms are identified and examined from 1896 to 2016 and the criteria for a 4th paradigm suggested for the period 2017-2056. The review examines the changes that have taken place in scientific understanding and in public trust, a few key developments and the associated establishment of the related organisational infrastructure designed to collate and assess the evidence.

  13. The Knowledge Society: A Sustainability Paradigm

    Naim Hamdija Afgan

    2010-10-01

    Full Text Available This paper defines the knowledge society as a human structured organisation based on contemporary developed knowledge and representing new quality of life support systems. It implies the need for a full understanding of distribution of knowledge, access to information and the capability to transfer information into a knowledge. The understanding of knowledge is the central challenge when defining a knowledge society. From our present perception of knowledge society, it is of interest to emphasize the role of the knowledge society in future development of human society. The life support systems are essential pillars of human society development. In this respect knowledge society represents a new paradigm for future development and it is strongly correlated to sustainable development. For this reason the sustainability paradigm of knowledge society is a potential frame for human society development leading to social cohesion, economic competitiveness and stability, use of resources and economic development, safeguarding biodiversity and the ecosystem.In order to verify the mutual relation between knowledge society and sustainability, we have to introduce the difference between these two terms. The knowledge society is based on the agglomeration of eco-knowledge, env-knowledge and soc-knowledge, it may be evaluated as the complex knowledge of quality of life support systems. We have to introduce metrics which will allow us to present knowledge as the paradigm of the number of indicators for verifying progress made.Sustainability metrics are designed to consolidate measures of economic, environmental and social performance of any system. It can be understood as a pattern for evaluation of the available knowledge about systems and their performance. In particular the decision-making process for the selection of the system under consideration must be based on the available knowledge. The link between knowledge and sustainability makes it possible for

    Apostolopoulos, Yorghos; Lemke, Michael K; Barry, Adam E; Lich, Kristen Hassmiller

    2018-02-01

    The drinking environment is a complex system consisting of a number of heterogeneous, evolving and interacting components, which exhibit circular causality and emergent properties. These characteristics reduce the efficacy of commonly used research approaches, which typically do not account for the underlying dynamic complexity of alcohol consumption and the interdependent nature of diverse factors influencing misuse over time. We use alcohol misuse among college students in the United States as an example for framing our argument for a complex systems paradigm. A complex systems paradigm, grounded in socio-ecological and complex systems theories and computational modeling and simulation, is introduced. Theoretical, conceptual, methodological and analytical underpinnings of this paradigm are described in the context of college drinking prevention research. The proposed complex systems paradigm can transcend limitations of traditional approaches, thereby fostering new directions in alcohol prevention research. By conceptualizing student alcohol misuse as a complex adaptive system, computational modeling and simulation methodologies and analytical techniques can be used. Moreover, use of participatory model-building approaches to generate simulation models can further increase stakeholder buy-in, understanding and policymaking. A complex systems paradigm for research into alcohol misuse can provide a holistic understanding of the underlying drinking environment and its long-term trajectory, which can elucidate high-leverage preventive interventions. © 2017 Society for the Study of Addiction.

    Ecological theory provides applications to biodiversity management but often falls short of expectations. One possibility is that heuristic theories of a young science are too immature. Logistic growth predicts a carrying capacity, but fisheries managed with the Lotka-Volterra paradigm continue to collapse. A second issue is that general predictions may not be useful. The theory of island biogeography predicts species richness but does not predict community composition. A third possibility is that the theory itself may not have much to do with nature, or that empirical parameterization is too difficult to know. The meta population paradigm is relevant to conservation, but meta populations might not be common in nature. For instance, empirical parameterization within the meta population paradigm is usually infeasible. A challenge is to determine why ecology fails to match needs of managers sometimes but helps at other. Managers may expect too much of paradigmatic blueprints, while ecologists believe them too much. Those who implement biodiversity conservation plans need simple, pragmatic guidelines based on science. Is this possible. What is possible An eclectic review of theory and practice demonstrate the power and weaknesses of the ideas that guide conservation and attempt to identify reasons for prevailing disappointment.

    2010-07-01

    Full Text Available This paper shows how a partial consilience might be achieved in the field of human development by means of principles from general systems theory. The author concurs with Sameroff (1989 that it is possible to interpret the mechanistic, organisimic, and contextualist paradigms/worldviews (Goldhaber, 2000; Pepper, 1970 in terms of general systems theory. The author selects a major developmentalist from each paradigm and interprets that scholar’s work in terms of systems principles. The following developmentalists were selected: Arnold Sameroff (contextualism, Erik Erickson (organicism, and Albert Bandura (mechanism. The systems principles employed are wholeness and order, self-stabilization, self-reorganization, hierarchical interaction, and dialectical contradiction (Sameroff, 1989. The author addresses the conflicting presuppositions of the major paradigms in order to provide for their theoretical subsuming under systems theory. Finally, the author notes areas of inconsistency that will need to be resolved in the future and calls for further scholarship to translate developmental theory in terms of general systems theory for the benefit of students, scholars, consultants and other practitioners familiar with systems theory.

    2012-01-01

    To explore the use of paradigms as ontological and philosophical guides for conducting PhD research. A paradigm can help to bridge the aims of a study and the methods to achieve them. However, choosing a paradigm can be challenging for doctoral researchers: there can be ambiguity about which paradigm is suitable for a particular research question and there is a lack of guidance on how to shape the research process for a chosen paradigm. The authors discuss three paradigms used in PhD nursing research: post-positivism, interpretivism and pragmatism. They compare each paradigm in relation to its ontology, epistemology and methodology, and present three examples of PhD nursing research studies to illustrate how research can be conducted using these paradigms in the context of the research aims and methods. The commonalities and differences between the paradigms and their uses are highlighted. Creativity and flexibility are important when deciding on a paradigm. However, consistency and transparency are also needed to ensure the quality and rigour necessary for conducting nursing research. When choosing a suitable paradigm, the researcher should ensure that the ontology, epistemology and methodology of the paradigm are manifest in the methods and research strategies employed.

    Full Text Available Architecture is facing a period of great challenges and possibilities, typical of all crises. In such periods, the paradigms we have taken for granted so far are the same ones that generated the crisis, therefore they should undergo a critical revision and new modes of thought and operation (driven by computation can be actively explored and pursued. Instead of retreating to intellectual “safe houses”, architecture should open itself up to and be restructured by the accelerated pace of change imposed by reality, renouncing obsolete methods of anticipating and exerting control and welcoming a more proactive behaviour. It is therefore of primary importance to promote the exercise of projective imagination.

Today in our country this process is stimulated by various competitions, including financing for the implementation of results. In training programs knowledge approach still prevails. The corresponding methods, along with stimulation, are included into educational programs in leading foreign educational institutions, mostly at universities. If in previous decades mostly divergent methods were studied (morphological analysis, the focal objects method, synectics, etc., then now the leading place is taken by theory of inventive problem solving – TRIZ created in the former USSR by G.S. Altshuller in connection with the increasing leading corporations requirement for specialists in TRIZ. This fact gives Russia essential competitive advantages in the innovative way of development. For effective use of this advantage it is important to form the TRIZ-based innovative thinking beginning from school days. For this purpose authors developed new methods in TRIZ-pedagogics, uniting metasubject results (in higher education institutions – competences into the system of innovative thinking. As a result, both educational and economic effects are achieved: the intellectual property created in educational process. For schools it is the possibility of significant improvement of financing causing importance of new mechanisms of intellectual property fixation, protection and implementation. Recommendations about creation of such system are provided in the article.

    A problem has been raised on the necessity to substitute the linear-nonthreshold hypothesis as a paradigm of radiation hygiene for the hypothesis of the biological effectiveness of ionizing irradiations. A comparison of the methodological substantiation for both hypotheses and a conception of 'acceptable risk' has been carried out. It is suggested that the possibility of theoretical substantiation of safety standards for the radiational factor on the basis of adatational hypothesis be acknowledged instead of the linear - nonthreshold conception which has lost its historic significance

    We obtain the relaxation time for the shear viscous stress for various geometries using the 'membrane paradigm' formula proposed recently. We consider the generic Schwarzschild-anti-de Sitter black holes (SAdS), the generic Dp-brane, the Klebanov-Tseytlin (KT) geometry, and the N=2* theory. The formula is the 'shear mode' result and is not fully trustable, but it may be helpful to learn some generic behaviors about the relaxation time. For example, a simple formula summarizes all known results for SAdS, and a single expression summarizes the results for the Dp-brane and the KT geometry.

  8. Three paradigms for the analysis of corruption

    2015-10-01

    Full Text Available In the last decades a growing awareness emerged of the relevance of corruption as an hidden factor which may negatively affect political and economic decision-making processes. In spite of a lively scientific debate there is no general consensus on a commonly accepted definition of what corruption is.The A. distinguishes three main paradigms, focusing on different (though not irreconcilable variables.The first is the economic paradigm, which usually takes the principal-agent model of corruption as its founding pillar. In this paradigm corruption is considered the outcome of rational individual choices, and its spread within a certain organization is influenced by the factors defining the structure of expected costs and rewards.A second approach – the cultural paradigm – looks at the differences in cultural traditions, social norms and interiorized values which shape individuals’ moral preferences and consideration of his social and institutional role. These are a leading forces that can push a corrupt public or private agent (not to violate legal norms.A third neo-institutional approach considers also mechanisms which allow the internal regulation of social interactions within corrupt networks, and their effects on individuals’ beliefs and preferences. Though the corrupt agreements cannot be enforced with legal sanctions, several informal, non-written rules, contractual provisos and conventions may regulate the corrupt exchange between agent and corruptor.The A. underlines that corruption is the outcome of a multitude of individual and collective choices which change public opinion towards corruption and its diffusion throughout the state, markets and civil society. There is no univocal recipe to deal with anti-bribery measures, since corruption is a complex and multifaceted phenomenon.Reforms aimed at dismantling systemic corruption have to be finely tuned against its hidden governance structures, i.e. its internal regulation of

    2013-09-01

    Full Text Available The marketing practices of the companies show that not all of them are observing ethical and moral standards and they manipulate the consumers. This paper has as main goal to examine the most usual unethical techniques, the present status of consumers’ power and how more power could work for a new marketing paradigm. There are many unethical marketing techniques which could be found in deceptive product recipes, packaging, promotion, prices and in other areas. Most consumers have no appropriate powers and tools to counteract the manipulation techniques and feel they have fewer rights than the marketers. The current state of empowerment of the consumer show that the European consumers are not in the best position in the market as the Consumer Empowerment Index proves. This matter of facts emphasizes a strong need for a better empowerment of the consumers. The consumer which has more power and wisely use it could improve the balance of power in the market. But the consumers should have a proactive buying behavior in order to get such results. These revolutionary consumers attack the structural roots of the social, economic and political problems which produces a new market ideology as a part of the new tier of transnational institutional ideology. This consumer behavior may have a strong influence toward a new marketing paradigm.

  12. Osteoporosis: Modern Paradigms for Last Century's Bones.

    2016-06-17

    The skeleton is a metabolically active organ undergoing continuously remodelling. With ageing and menopause the balance shifts to increased resorption, leading to a reduction in bone mineral density and disruption of bone microarchitecture. Bone mass accretion and bone metabolism are influenced by systemic hormones as well as genetic and lifestyle factors. The classic paradigm has described osteoporosis as being a "brittle bone" disease that occurs in post-menopausal, thin, Caucasian women with low calcium intakes and/or vitamin D insufficiency. However, a study of black women in Africa demonstrated that higher proportions of body fat did not protect bone health. Isoflavone interventions in Asian postmenopausal women have produced inconsistent bone health benefits, due in part to population heterogeneity in enteric bacterial metabolism of daidzein. A comparison of women and men in several Asian countries identified significant differences between countries in the rate of bone health decline, and a high incidence rate of osteoporosis in both sexes. These studies have revealed significant differences in genetic phenotypes, debunking long-held beliefs and leading to new paradigms in study design. Current studies are now being specifically designed to assess genotype differences between Caucasian, Asian, African, and other phenotypes, and exploring alternative methodology to measure bone architecture.

  13. Imaging deductive reasoning and the new paradigm

    2015-01-01

    There has been a great expansion of research into human reasoning at all of Marr’s explanatory levels. There is a tendency for this work to progress within a level largely ignoring the others which can lead to slippage between levels (Chater et al., 2003). It is argued that recent brain imaging research on deductive reasoning—implementational level—has largely ignored the new paradigm in reasoning—computational level (Over, 2009). Consequently, recent imaging results are reviewed with the focus on how they relate to the new paradigm. The imaging results are drawn primarily from a recent meta-analysis by Prado et al. (2011) but further imaging results are also reviewed where relevant. Three main observations are made. First, the main function of the core brain region identified is most likely elaborative, defeasible reasoning not deductive reasoning. Second, the subtraction methodology and the meta-analytic approach may remove all traces of content specific System 1 processes thought to underpin much human reasoning. Third, interpreting the function of the brain regions activated by a task depends on theories of the function that a task engages. When there are multiple interpretations of that function, interpreting what an active brain region is doing is not clear cut. It is concluded that there is a need to more tightly connect brain activation to function, which could be achieved using formalized computational level models and a parametric variation approach.

    2018-03-01

    Full Text Available The formation of the modern conception of human capital is connected with the development of post-industrial information society, knowledge economy and digital economy. The main role in analyzing of the content and role of human capital can play a new institutional economic theory. It is determined that the methodology of research of paradigm change in economic science remains the subject of discussion. The conception of institutional paradigm of human capital development can be attributed to the new economy, the development of which is carried out on the condition that the employee is not always alienated from the relationships of ownership: he himself becomes the owner of the «new» economic resources. The factors of education along with the factors of health care which are determining in the development of human capital are researched. Special attention is paid to education, as it acts as an intellectual capital of the new economy, where knowledge and skills become the «intellectual 5D printer», producing the modern human capital. The transition to a new, post-industrial economy is characterized by a major long-term tendency: the progress of knowledge and the increasing complexity of the socio-economic life; created by powerful factors of information and computer technologies and leading to expansion of global economic space.

  15. Passage of American shad: paradigms and realities

    2012-01-01

    Despite more than 250 years of development, the passage of American shad Alosa sapidissima at dams and other barriers frequently remains problematic. Few improvements in design based on knowledge of the swimming, schooling, and migratory behaviors of American shad have been incorporated into passage structures. Large-scale technical fishways designed for the passage of adult salmonids on the Columbia River have been presumed to have good performance for American shad but have never been rigorously evaluated for this species. Similar but smaller fishway designs on the East Coast frequently have poor performance. Provision of effective downstream passage for both juvenile and postspawning adult American shad has been given little consideration in most passage projects. Ways to attract and guide American shad to both fishway entrances and downstream bypasses remain marginally understood. The historical development of passage structures for American shad has resulted in assumptions and paradigms about American shad behavior and passage that are frequently unsubstantiated by supporting data or appropriate experimentation. We propose that many of these assumptions and paradigms are either unfounded or invalid and that significant improvements to American shad upstream and downstream passage can be made via a sequential program of behavioral experimentation, application of experimental results to the physical and hydraulic design of new structures, and controlled tests of large-scale prototype structures in the laboratory and field.

  16. New paradigms of Game Theory from globalization

    Full Text Available Games Theory constitutes a model by means every player tries to predict what they will make the other players in reply to his own actions, and to optimize the result of the above mentioned actions in his benefit knowing that the others are thinking to about the same form. The development of the theory supposed a boom after the World War II, which happened of analyzing exclusively competitive behaviors to considering situations with competitive and cooperative characteristics. Nevertheless, the advance of the humanity and the disappearance of both geopolitical blocks have eliminated the balance of power and have produced the emergence of a world the most based on the exclusive conquest of the power. This has originated the model change and dilemmas, happening from the most cooperative models (Prisoner’s Dilemma or from the models of the Cold War (Dilemma of the Gallina up to reaching the dilemmas of the Leader or of the Hero. This change of paradigm owes to the extension of the globalization, which originates an immeasurable loss of economic, social, political power, of human rights, which they have affected negatively to the poor people. In this paper is studied the change of paradigm caused by the consequences of the globalization and the geopolitical transformations in a monopolar world, analyzing the consequences on the basis of the Theory of Games.

  17. Tolerance of sexual harassment: a laboratory paradigm.

    Angelone, David J; Mitchell, Damon; Carola, Kara

    2009-12-01

    The present study attempted to develop a laboratory analogue for the study of tolerance for sexual harassment by using an online speed-dating paradigm. In that context, the relation between participants' sexual harassment attitudes, perpetrator attractiveness, perpetrator status, and perceived dating potential of the perpetrator were examined as factors influencing participants' tolerance of sexually harassing behavior. Participants were 128 female college students from a small northeastern public university. Results indicated that attractiveness, high social status, and attitudinal beliefs about sexual harassment were all predictive of tolerance for sexual harassment, providing preliminary support for the validity of this paradigm. In addition, participants' self reported likelihood to date a bogus male dating candidate was also predictive of tolerance for sexual harassment, over and above the aforementioned variables, suggesting that dating potential can play a role in perceptions of sexual harassment. Further, this experiment demonstrated that perceptions of sexual harassment can be assessed using the in vivo measurement of behavior. In addition, using an online environment not only provides a contemporary spin and adds a greater degree of external validity compared to other sexual harassment analogues, it also reduces any risk of potential physical sexual contact for participants.

  18. Colloidal paradigm in supercapattery electrode systems

    Science.gov (United States)

    Chen, Kunfeng; Xue, Dongfeng

    2018-01-01

    Among decades of development, electrochemical energy storage systems are now sorely in need of a new design paradigm at the nano size and ion level to satisfy the higher energy and power demands. In this review paper, we introduce a new colloidal electrode paradigm for supercapattery that integrates multiple-scale forms of matter, i.e. ion clusters, colloidal ions, and nanosized materials, into one colloid system, coupled with multiple interactions, i.e. electrostatic, van der Waals forces, and chemical bonding, thus leading to the formation of many redox reactive centers. This colloidal electrode not only keeps the original ionic nature in colloidal materials, but also creates a new attribute of high electroactivity. Colloidal supercapattery is a perfect application example of the novel colloidal electrode, leading to higher specific capacitance than traditional electrode materials. The high electroactivity of the colloidal electrode mainly comes from the contribution of exposed reactive centers, owing to the confinement effect of carbon and a binder matrix. Systematic and thorough research on the colloidal system will significantly promote the development of fundamental science and the progress of advanced energy storage technology.

  19. Understanding emerging treatment paradigms in rheumatoid arthritis.

    Breedveld, Ferdinand C; Combe, Bernard

    2011-05-25

    Treatment strategies for rheumatoid arthritis (RA) will continue to evolve as new drugs are developed, as new data become available, and as our potential to achieve greater and more consistent outcomes becomes more routine. Many patients will find both symptom relief and modest control of their disease with disease-modifying antirheumatic drugs (DMARDs), yet this course of therapy is clearly not effective in all patients. In fact, despite strong evidence that intensive treatment in the early stages of RA can slow or stop disease progression and may prevent disability, many patients continue to be managed in a stepwise manner and are treated with an ongoing monotherapy regimen with DMARDs. There is now a large body of evidence demonstrating the success of treating RA patients with anti-TNF therapy, usually in combination with methotrexate. As a result of the increased use of anti-TNF therapy, treatment paradigms have changed - and our practice is beginning to reflect this change. In the present review, we summarize the salient points of several recently proposed and emerging treatment paradigms with an emphasis on how these strategies may impact future practice.

  20. A new guiding paradigm for waste disposal

    International Nuclear Information System (INIS)

    Suter, Peter

    2003-01-01

    New situations call for a revision of strategies in the waste recycling and recovery sector. The guiding paradigm is that the evaluation and optimization of strategies ought to be integral, i.e. it ought to incorporate all steps from cradle to grave, all cost components and also to take into account all environmental aspects, as well as resource depletion. Furthermore, all variants of a comparison must have the same output and the same boundaries in space and time. Total cost (comprising also environmental damage and resource depletion) is proposed here as the evaluation function; environmental damage can be made operational by the DALY concept (Hofstetter P. Perspectives in life cycle impact assessment. Boston: Kluwer Academic, 1998) ('disability adjusted loss of life years') accounting for the years of life lost due to premature death, to illness or annoyance. The search for optimal strategies in the waste sector evidently requires the solution of a system with an enormous number of parameters; the method of genetic algorithms may represent a suitable solution paradigm, leading to the result in a reasonable computing time

    Bradshaw, David J; Lynch, Richard J M

    2013-12-01

    The microbial and dietary factors that drive caries have been studied scientifically for 120 years. Frequent and/or excessive sugar (especially sucrose) consumption has been ascribed a central role in caries causation, while Streptococcus mutans appeared to play the key role in metabolising sucrose to produce lactic acid, which can demineralise enamel. Many authors described caries as a transmissible infectious disease. However, more recent data have shifted these paradigms. Streptococcus mutans does not fulfil Koch's postulates - presence of the organism leading to disease, and absence of the organism precluding disease. Furthermore, molecular microbiological methods have shown that, even with a sugar-rich diet, a much broader spectrum of acidogenic microbes is found in dental plaque. While simple sugars can be cariogenic, cooked starches are also now recognised to be a caries threat, especially because such starches, while not 'sticky in the hand', can be highly retentive in the mouth. Metabolism of starch particles can yield a prolonged acidic challenge, especially at retentive, caries-prone sites. These changes in the paradigms of caries aetiology have important implications for caries control strategies. Preventing the transmission of S. mutans will likely be inadequate to prevent caries if a sufficiently carbohydrate-rich diet continues. Similarly, restriction of sucrose intake, although welcome, would be unlikely to be a panacea for caries, especially if frequent starch intake persisted. Instead, approaches to optimise fluoride delivery, to target plaque acidogenicity or acidogenic microbes, to promote plaque alkali generation, to increase salivary flow or replace fermentable carbohydrates with non-fermentable alternatives may be more promising. © 2013 FDI World Dental Federation.

    2012-01-01

    Future generations of NASA and U.S. Air Force vehicles will require lighter mass while being subjected to higher loads and more extreme service conditions over longer time periods than the present generation. Current approaches for certification, fleet management and sustainment are largely based on statistical distributions of material properties, heuristic design philosophies, physical testing and assumed similitude between testing and operational conditions and will likely be unable to address these extreme requirements. To address the shortcomings of conventional approaches, a fundamental paradigm shift is needed. This paradigm shift, the Digital Twin, integrates ultra-high fidelity simulation with the vehicle s on-board integrated vehicle health management system, maintenance history and all available historical and fleet data to mirror the life of its flying twin and enable unprecedented levels of safety and reliability.

Although this approach is widely used in patient studies, differences in the ability to perform such color comparisons might simply reflect participants’ general knowledge of object colors rather than their ability to generate accurate visual mental images of the colors of ...

    1995-01-01

    Over the last 5 years, refining companies have not performed well financially, generating returns below the cost of capital. Environmental regulations have caused the industry to invest significant amounts of capital, and while new regulations will cause the shutdown of between 500 thousand and 1.2 million barrels per day of capacity, the industry structure will remain poor and financial returns for the average player will likely be volatile, cyclical, and below the cost of capital. Based on this industry outlook, refining companies seeking superior performance will have to break the traditional paradigms and adopt world-class practices used in other industries. Changes required to significantly improve financial returns will include shifts in business strategy to accommodate growth, and development of nontraditional services, as well as initiates to dramatically reshape cost structure and improve profitability. Making the changes to become a superior performer in the refining business will require a clear vision and strong leadership at multiple levels in the organization. The transformation will also require changes in company culture and incentive plans that encourage managers to act as owners. In addition, superior performers will push accountability for results to low levels in the organization. Given the herd mentality of the oil industry, superior performers must take decisive, preemptive action to generate a substantial, competitive advantage

    2016-12-01

    Full Text Available It is hard to provide an unequivocal answer to the question of whether or not thought suppression is effective. Two thought suppression paradigms - the “white bear” paradigm and the think/no-think paradigm - give mixed results. Generally, “white bear” experiments indicate that thought suppression is counterproductive, while experiments in the think/no-think paradigm suggest that it is possible to effectively suppress a thought. There are also alternative methods used to study thought suppression, for instance the directed forgetting paradigm or the Stroop task. In the article, I describe the research methods used to explore thought suppression efficacy. I focus on the “white bear” and the think/no-think paradigms and discuss theories proposed to explain the results obtained. I also consider the internal and external validity of the methods used.

  12. Vascular access surveillance: case study of a false paradigm.

    Paulson, William D; Moist, Louise; Lok, Charmaine E

    2013-01-01

    The hemodialysis vascular access surveillance controversy provides a case study of how enthusiasm for a new test or treatment can lead to adoption of a false paradigm. Paradigms are the beliefs and assumptions shared by those in a field of knowledge, and are commonly included in clinical practice guidelines. The guidelines of the National Kidney Foundation Kidney Disease Outcomes Quality Initiative recommend that arteriovenous vascular accesses undergo routine surveillance for detection and correction of stenosis. This recommendation is based on the paradigm that surveillance of access blood flow or dialysis venous pressure combined with correction of stenosis improves access outcomes. However, the quality of evidence that supports this paradigm has been widely criticized. We tested the validity of the surveillance paradigm by applying World Health Organization (WHO) criteria for evaluating screening tests to a literature review of published vascular access studies. These criteria include four components: undesired condition, screening test, intervention, and desired outcome. The WHO criteria show that surveillance as currently practiced fails all four components and provides little or no significant benefit, suggesting that surveillance is a false paradigm. Once a paradigm is established, however, challenges to its validity are usually resisted even as new evidence indicates the paradigm is not valid. Thus, it is paramount to apply rigorous criteria when developing guidelines. Regulators may help promote needed changes in paradigms when cost and safety considerations coincide. © 2013 Wiley Periodicals, Inc.

  13. [The template principle: paradigm of modern genetics].

    Inge-Vechtomov, S G

    2013-01-01

    The idea of continuity in living systems, which was initially developed in mid-19th century, reached its peak in 1928 thanks to N.K. Koltsov, who proposed the template principle in chromosome reproduction. The determination of genetic functions of nucleic acids and the advent of molecular genetics led to F. Crick's statement of the central dogma of molecular biology in 1958. This dogma became a contemporary version of the template principle (templates of the first order). The discovery of "protein inheritance" underlay the notion of steric or conformational templates (second order) for reproducing conformation in a number of proteins. The template principle supplemented by this notion claims to be the main paradigm of modern genetics.

    The Transferable, Adaptable, Modular and Upgradeable (TAMU) Flight Production Process (FPP) is a model-centric System of System (SoS) framework which cuts across multiple organizations and their associated facilities, that are, in the most general case, in geographically diverse locations, to develop the architecture and associated workflow processes for a broad range of mission operations. Further, TAMU FPP envisions the simulation, automatic execution and re-planning of orchestrated workflow processes as they become operational. This paper provides the vision for the TAMU FPP paradigm. This includes a complete, coherent technique, process and tool set that result in an infrastructure that can be used for full lifecycle design and decision making during any flight production process. A flight production process is the process of developing all products that are necessary for flight.

    The wider applications of nanoparticles (NPs) has evoked a world-wide concern due to their possible risk of toxicity in humans and other organisms. Aggregation and accumulation of NPs into cell leads to their interaction with biological macromolecules including proteins, nucleic acids and cellular organelles, which eventually induce toxicological effects. Application of toxicogenomics to investigate molecular pathway-based toxicological consequences has opened new vistas in nanotoxicology research. Indeed, genomic approaches appeared as a new paradigm in terms of providing information at molecular levels and have been proven to be as a powerful tool for identification and quantification of global shifts in gene expression. Toxicological responses of NPs have been discussed in this chapter with the aim to provide a clear understanding of the molecular mechanism of NPs induced toxicity both in in vivo and in vitro test models.

This issue features a series of articles, with clinical cases, each presented to illustrate the challenges faced by individuals and couples whose sexual and gender identities and expressions do not comport with traditional and cultural norms. These articles also document the challenges to the therapists who treat them. Considered individually, each article underscores the need to recognize the importance of evidence in guiding psychotherapy in cases involving sexuality. The discussions in each article offer recommendations meant to help and guide psychotherapists. Considered collectively, they raise important questions and considerations about shifting paradigms of human sexuality. Implications for assessment and treatment of cases involving sexuality and gender identity are discussed and recommended. © 2017 Wiley Periodicals, Inc.

    Systems healthcare is a holistic approach to health premised on systems biology and medicine. The approach integrates data from molecules, cells, organs, the individual, families, communities, and the natural and man-made environment. Both extrinsic and intrinsic influences constantly challenge the biological networks associated with wellness. Such influences may dysregulate networks and allow pathobiology to evolve, resulting in early clinical presentation that requires astute assessment and timely intervention for successful mitigation. Herein, we describe the components of relevant biological systems and the nature of progression from at-risk to manifest disease. We illustrate the systems approach by examining two relevant clinical examples: Alzheimer's and cardiovascular diseases. The implications of systems healthcare management are examined through the lens of economics, ethics, policy and the law. Finally, we propose the need to develop new educational paradigms to enhance the training of the health professional in an era of systems medicine.

    The aim of this article is to study how policy learning has led to new understandings of ways to support renewable energies, based on experience in the wind power sector. Drawing on analysis of the literature and informed by field-work in the wind power sector in Denmark, France and the UK, it explores the extent to which policy learning over the medium term has brought us closer to models that integrate economic, environmental and societal desiderata into renewables policy in a manner congruent with the sustainable development aspirations espoused by the European Union and its constituent states. It contributes to policy theory development by arguing in favour of a new policy paradigm that reaches beyond measures to increase production capacity per se to embrace both the institutional dynamics of innovation processes and the fostering of societal engagement in implementation processes

    In this paper we introduce a new ubiquitous computing paradigm for behavioral health care: "Interreality". Interreality integrates assessment and treatment within a hybrid environment, that creates a bridge between the physical and virtual worlds. Our claim is that bridging virtual experiences (fully controlled by the therapist, used to learn coping skills and emotional regulation) with real experiences (allowing both the identification of any critical stressors and the assessment of what has been learned) using advanced technologies (virtual worlds, advanced sensors and PDA/mobile phones) may improve existing psychological treatment. To illustrate the proposed concept, a clinical scenario is also presented and discussed: Daniela, a 40 years old teacher, with a mother affected by Alzheimer's disease.

    Social network use continues to increase in the majority of regions around the world, with a global increase of 17.6% in 2012, and another projected 12.6% in 2014 (digital.org, 2014). Social media have also been incorporated into daily routines of American journalists, with 53.8% reporting...... that they use microblogs like Twitter on a regular basis to both gather and disseminate information (Willnat & Weaver, 2014). The aim of this study is to investigate how social media, more specifically, social media guidelines, implemented at the organizational level intercede with journalism practices...... and if these guidelines challenge the news paradigm. While using social media have been a “loop-hole” of sorts to disseminating political information in countries that have strong censorship (the Arab Spring being a premiere example, Eltantawy & Wiest, 2011; Lotan, Graeff, Ananny, Gaffney, & Pearce, 2011), journalists...

    The Bayesian paradigm comprises a unified and consistent framework for analyzing and expressing risk. Yet, we see rather few examples of applications where the full Bayesian setting has been adopted with specifications of priors of unknown parameters. In this paper, we discuss some of the practical challenges of implementing Bayesian thinking and methods in risk analysis, emphasizing the introduction of probability models and parameters and associated uncertainty assessments. We conclude that there is a need for a pragmatic view in order to 'successfully' apply the Bayesian approach, such that we can do the assignments of some of the probabilities without adopting the somewhat sophisticated procedure of specifying prior distributions of parameters. A simple risk analysis example is presented to illustrate ideas

  6. The complexity paradigm in management reconceptualizing

    2005-01-01

    Full Text Available Chaos and complexity theory is a special, functionalist systems approach to dealing with complex, dynamic, nonlinear systems. Through treating organizations as complex, with their environments coevolving, nonlinear systems, complexity theory is aimed at creative research of their erratic nature. When an organization is in a state of bounded instability, at the edge of chaos, order and disorder are intertwined, its behavior is irregular and unpredictable but has some pattern. According to the complexity paradigm organizations have to strive to avoid the equilibrium states of stability and instability. They have instead to strive to remain in a state of bounded instability, at the edge of chaos, where they are able to display their full potential for creativity and innovation.

    Causality provides a natural structure for organizing our experience and language. Causal reasoning during speech production is a distinct aspect of verbal communication, whose related brain processes are yet unknown. The aim of the current study was to investigate the neural mechanisms underlying the continuous generation of cause-and-effect coherences during overt word production. During fMRI data acquisition participants performed three verbal fluency tasks on identical cue words: A novel causal verbal fluency task (CVF), requiring the production of multiple reasons to a given cue word (e.g. reasons for heat are fire, sun etc.), a semantic (free association, FA, e.g. associations with heat are sweat, shower etc.) and a phonological control task (phonological verbal fluency, PVF, e.g. rhymes with heat are meat, wheat etc.). We found that, in contrast to PVF, both CVF and FA activated a left lateralized network encompassing inferior frontal, inferior parietal and angular regions, with further bilateral activation in middle and inferior as well as superior temporal gyri and the cerebellum. For CVF contrasted against FA, we found greater bold responses only in the left middle frontal cortex. Large overlaps in the neural activations during free association and causal verbal fluency indicate that the access to causal relationships between verbal concepts is at least partly based on the semantic neural network. The selective activation in the left middle frontal cortex for causal verbal fluency suggests that distinct neural processes related to cause-and-effect-relations are associated with the recruitment of middle frontal brain areas.

    Kuhn's ( 1962 ) acknowledgement of a paradigm as a way that scientists make sense of their world and its reality gave recognition to the idea of 'paradigm shift'. This shift exposes the transience of paradigm development shaped by societal and scientific evolution. This ongoing evolutionary development provides the researcher with many paradigms to consider regarding how research is undertaken and the search for understanding achieved. An understanding of paradigm development is necessary when planning a study and can shape the search for understanding. It is hoped that the discussion presented here will assist novice and experienced researchers in articulating the rationales for their paradigm choices. An overview of the dominant paradigms is presented, reflecting ongoing paradigm development shaped by ontological, epistemological and methodological perspectives. Potential paradigm choices that shape research aims, objectives and focus in the search for understanding are considered. The inherent debates about paradigm shift, division, war and synthesis leave the researcher many perspectives to consider. Articulating the world views underpinning constructivism, interpretivism and pragmatism is particularly challenging because of the blurring of boundaries between them. The evolutionary nature of paradigmatic development has provided nurse researchers with the opportunity for methodological openness to the myriad research approaches, methods and designs that they may choose to answer their research question. However, it is imperative that researchers consider their ontological stances and the nature of their research questions. This is challenging in constructivism, interpretivism and pragmatism, where there is often an overlap of paradigm world views. ©2018 RCN Publishing Company Ltd. All rights reserved.

    Different aspects of philosophy are derived from different paradigms that contain various main points, some of which are repeated or overlap. Belief and practice are two components of a paradigm that provide perspective and framework and lead to nursing research. Changes in healthcare have popularized empirical and evidence-based research in the field of nursing research. However, the evidence-base study approach has given rise to a certain level of debate. Until now, no standard paradigm has been established for the nursing field, as different professionals use different paradigms in their studies. Such provides certain limitations as well as advantages. The quantitative aspects of a nursing paradigm were developed by Peplau and Henderson (1950) and Orem (1980). Such remained the standard until 1990, when Guba and Parse proposed qualitative viewpoints in contextual features. Therefore, the nursing paradigm has made great contributions to the development of knowledge in nursing care, although debate continues due to incomplete knowledge attributable to the presentation of knowledge and insight within individually developed paradigms. It is better to apply multiple paradigms to different research questions. It is suggested that better communication amongst experts regarding their individual points of view would help nursing members to integrate findings within the global pool of knowledge and allow replication over multiple studies.

    2009-01-01

    In the Afterword to the second edition of the book "Estimation of Dependences Based on Empirical Data" by V. Vapnik, an advanced learning paradigm called Learning Using Hidden Information (LUHI) was introduced. This Afterword also suggested an extension of the SVM method (the so called SVM(gamma)+ method) to implement algorithms which address the LUHI paradigm (Vapnik, 1982-2006, Sections 2.4.2 and 2.5.3 of the Afterword). See also (Vapnik, Vashist, & Pavlovitch, 2008, 2009) for further development of the algorithms. In contrast to the existing machine learning paradigm where a teacher does not play an important role, the advanced learning paradigm considers some elements of human teaching. In the new paradigm along with examples, a teacher can provide students with hidden information that exists in explanations, comments, comparisons, and so on. This paper discusses details of the new paradigm and corresponding algorithms, introduces some new algorithms, considers several specific forms of privileged information, demonstrates superiority of the new learning paradigm over the classical learning paradigm when solving practical problems, and discusses general questions related to the new ideas.

    2010-01-01

    A fresh look at the question of randomness was taken in the theory of computing: A distribution is pseudorandom if it cannot be distinguished from the uniform distribution by any efficient procedure. This paradigm, originally associating efficient procedures with polynomial-time algorithms, has been applied with respect to a variety of natural classes of distinguishing procedures. The resulting theory of pseudorandomness is relevant to science at large and is closely related to central areas of computer science, such as algorithmic design, complexity theory, and cryptography. This primer surveys the theory of pseudorandomness, starting with the general paradigm, and discussing various incarnations while emphasizing the case of general-purpose pseudorandom generators (withstanding any polynomial-time distinguisher). Additional topics include the "derandomization" of arbitrary probabilistic polynomial-time algorithms, pseudorandom generators withstanding space-bounded distinguishers, and several natural notions...

    2017-07-01

    Motor imagery (MI) has been widely used in neurorehabilitation and brain computer interface. The size of event-related desynchronization (ERD) is a key parameter for successful motor imaginary rehabilitation and BCI adaptation. Many studies have used visual guidance for enhancement/ amplification of motor imagery ERD amplitude, but their enhancements were not significant. We propose a novel ERD enhancing paradigm using body-ownership illusion, or also known as rubber hand illusion (RHI). The system was made by motorized, moving rubber hand which can simulate wrist extension. The amplifying effects of the proposed RHI paradigm were evaluated by comparing ERD sizes of the proposed paradigm with motor imagery and actual motor execution paradigms. The comparison result shows that the improvement of ERD size due to the proposed paradigm was statistically significant (pparadigms.

    We discuss Learning by Observing and Pitching In (LOPI) as a cultural paradigm that provides an interesting alternative to Assembly-Line Instruction for supporting children's learning. Although LOPI may occur in all communities, it appears to be especially prevalent in many Indigenous and Indigenous-heritage communities of the Americas. We explain key features of this paradigm, previewing the chapters of this volume, which examine LOPI as it occurs in the lives of families and communities. In this introductory chapter, we focus especially on one feature of the paradigm that plays an important role in its uptake and maintenance in families, institutions, and communities-the nature of assessment. We consider the power of the dominant paradigm and the challenges in making paradigm shifts. © 2015 Elsevier Inc. All rights reserved.

  15. Towards new paradigms for the treatment of hypobaric decompression sickness.

    1998-04-01

    Altitude induced (hypobaric) decompression sickness (DCS) has long been treated with ground level oxygen and U.S. Navy Treatment Tables 5 and 6. These treatment tables originate from surface excursion diving and, when implemented, require significant resource allocation. Although they are effective treatment regimens, these tables were not developed for treating hypobaric DCS which has an etiology similar to saturation diving DCS. In this review, different treatment options for hypobaric DCS are presented. These options include more aggressive use of ground level oxygen and treatment tables using a maximum pressure of 2 atmospheres (ATA). Specific attention is given to USAF Table VIII, an experimental hypobaric DCS treatment-table, and space suit overpressurization treatment. This paradigm shift for DCS treatment is based on a projected increase in hypobaric DCS treatment from exposure to low pressure during several operational conditions: cruise flight in the next generation aircraft (e.g., F-22); high altitude, unpressurized flight by special operations forces; and the extraordinary amount of extravehicular activity (EVA) required to construct the international space station. Anticipating the need to treat DCS encountered during these and other activities, it is proposed that 2 ATA or less hyperbaric oxygen (HBO) treatment conjoined with new collapsible chamber technology can be used to address these issues in a safe and cost effective fashion.

    Full Text Available Today, the fastest rates of scientific and technological development are typical for the spheres of nano-systems and materials industry, information and communication systems, as well as spheres of direct human impact on environment - power industry, urbanization, and industrial infrastructure. Accelerate replacement of a human by machines and robots, the construction of megacities; the transportation of huge volumes of environmentally hazardous goods takes place against the background of intensive generation of knowledge, the transition of the results of fundamental research into specific production technologies. In this process, on the one hand, a fundamentally new format for technological restructuring of the world economy is being developed. On the other hand, a new platform for human-environment interaction is being formed, where both positive and negative environmental impacts will be determined by unstudied factors in the near future. The reason for this is in the forthcoming replacement of the technologies that are familiar to us, although dynamically developing, by fundamentally new - convergent. Entering the front line of technological development - NBIC-convergence - requires a new paradigm of sustainable development.

    Full Text Available As institutions of knowledge generation and diffusion, in the course of their activities universities should take into account not only the level of an organization or a country but also that of individual knowledge transformation, whereby creating favorable conditions for developing creativity of both graduates and academic staff who form the basis of the intellectual capital of the university and the country. While functioning in the global competitive climate, the national intellectual capital is a factor of socio-economic development and international competitive status of individual countries. During decades the concept of university has been evolving toward determining the operation mode of a university as that of an institution providing mass education, carrying out fundamental and applied researches as well as largely participating in local, national and global development. However, the university operation paradigm remains eclectic. Equal relationships between universities, government and industry in a knowledge-based society are well-defined by the concept of triple helix innovation systems engaging NGOs. World-class universities tend ever more to incorporate the feature of an entrepreneurial university actively competing in the global academic domain.

The energy source of the gravitational power P g r , which heats and contracts the Bok’s gas globules harbouring the future stars, is identified and defined as well as the gravitational power generated on the solid / fluid planets. Calculations are carried out to make the comparison between P g r predicted for the solar giant planets and the measured infrared radiation power P int coming from the interior. The case of planets with solid crust (Earth, etc. requires a particular attention due to the threat to stability produced by the thermal dilatation. An analysis is done of the Earth’s planetary equilibrium which may be attained eliminating the temperature rise through the migration of hot internal magma across the crust fractured by earth- quakes. The temperatures observed up to 420,000 years ago in Antartica through Vostok and Epica ice cores suggest the possibility that the Earth gravitational power P g r may be radiated in space through these temperature cycles (Glacial Eras. In this general frame the Earth’s high seismicity and the dynamics of Plate tectonics may find their origin.

    2018-04-01

    Simultaneous Localization and Mapping (SLAM) is one of the most challenging research areas within computer and machine vision for automated scene commentary and explanation. The SLAM technique has been a developing research area in the robotics context during recent years. By utilizing the SLAM method robot can estimate the different positions of the robot at the distinct points of time which can indicate the trajectory of robot as well as generate a map of the environment. SLAM has unique traits which are estimating the location of robot and building a map in the various types of environment. SLAM is effective in different types of environment such as indoor, outdoor district, Air, Underwater, Underground and Space. Several approaches have been investigated to use SLAM technique in distinct environments. The purpose of this paper is to provide an accurate perceptive review of case history of SLAM relied on laser/ultrasonic sensors and camera as perception input data. In addition, we mainly focus on three paradigms of SLAM problem with all its pros and cons. In the future, use intelligent methods and some new idea will be used on visual SLAM to estimate the motion intelligent underwater robot and building a feature map of marine environment.

    Today, the fastest rates of scientific and technological development are typical for the spheres of nano-systems and materials industry, information and communication systems, as well as spheres of direct human impact on environment - power industry, urbanization, and industrial infrastructure. Accelerate replacement of a human by machines and robots, the construction of megacities; the transportation of huge volumes of environmentally hazardous goods takes place against the background of intensive generation of knowledge, the transition of the results of fundamental research into specific production technologies. In this process, on the one hand, a fundamentally new format for technological restructuring of the world economy is being developed. On the other hand, a new platform for human-environment interaction is being formed, where both positive and negative environmental impacts will be determined by unstudied factors in the near future. The reason for this is in the forthcoming replacement of the technologies that are familiar to us, although dynamically developing, by fundamentally new - convergent. Entering the front line of technological development - NBIC-convergence - requires a new paradigm of sustainable development.

  2. Anthropology of music: Paradigms and perspectives

    Full Text Available Music represents a relational category, in the sense that people write meaning into it, and later by the means of the same music they write the meaning into other people. Therefore, I regard music as a cultural construct. Music does not possess universal meanings, but it forms its numerous meanings in different cultural environments, as well as in different individual perceptions. In anthropology, music is not studied in relation to its musical characteristics or aesthetical values. Anthropologists study its role in a wider social system, and strive to understand, by analysing the role of music in a society, the social and cultural system it belongs to - musical structure is less important here. The goal of the paper is to give an overview of the paradigms in ethnology and anthropology which have been used in studying music. In addition, a hypothetical-theoretical framework for studying music in institutions is set. Although the theory of hubs, which is presented here as a potential framework for studying music in institutions, is exemplified by traditional music, it can be applied to any genre of music. The basic theoretical framework offered by the authors Nadia Kiwan and Hanna Mainhof has been supplemented by certain parts which the author thought appropriate for studying music in institutions, both in ethnological and anthropological discourse.

  3. Paradigm transition in cosmic plasma physics

    1982-01-01

    In situ measurements in the magnetospheres together with general advancement in plasma physics are now necessitating introduction of a number of effects that have been recently discovered or earlier neglected. Examples are: electric double layers (like in the lower magnetosphere); thin current layer (like in the magnetopause) giving space a cellular structure; current produced filaments (e.g., in prominences, solar corona and interstellar clouds). Further it is important to use the electric current (particle) description and to study the whole circuit in which the current flows. The pinch effect cannot be neglected as is now usually done. The critical velocity phenomenon is essential, for example for the band structure of solar system. Theory of dusty plasmas is important. The result is a change in so many theories in cosmic plasma physics that it is appropriate to speak of an introduction of a new paradigm. This should be based on empirical knowledge from magnetospheric and laboratory investigations. Its application to astrophysics in general, including cosmology, will necessarily lead to a revision of, e.g., the present theories of the formation of stars, planets and satellites. It is doubtful whether the big bang cosmology will survive. (Auth.)

  4. Changing the paradigm for engineering ethics.

    Modern philosophy recognizes two major ethical theories: deontology, which encourages adherence to rules and fulfillment of duties or obligations; and consequentialism, which evaluates morally significant actions strictly on the basis of their actual or anticipated outcomes. Both involve the systematic application of universal abstract principles, reflecting the culturally dominant paradigm of technical rationality. Professional societies promulgate codes of ethics with which engineers are expected to comply (deontology), while courts and the public generally assign liability to engineers primarily in accordance with the results of their work, whether intended or unintended (consequentialism). A third option, prominent in ancient philosophy, has reemerged recently: virtue ethics, which recognizes that sensitivity to context and practical judgment are indispensable in particular concrete situations, and therefore rightly focuses on the person who acts, rather than the action itself. Beneficial character traits--i.e., virtues--are identified within a specific social practice in light of the internal goods that are unique to it. This paper proposes a comprehensive framework for implementing virtue ethics within engineering.

    Prototypes of 21st century management, especially for large scale enterprises, may well be found within the aerospace industry. The space era inaugurated a number of projects of such scope and magnitude that another type of management had to be created to ensure successful achievement. The challenges will be not just in terms of technology and its management, but also human and cultural in dimension. Futurists, students of management, and those concerned with technological administration would do well to review the literature of emerging space management for its wider implications. NASA offers a paradigm, or demonstrated model, of future trends in the field of management at large. More research is needed on issues of leadership for Earth based project in space and space based programs with managers there. It is needed to realize that large scale technical enterprises, such as are undertaken in space, require a new form of management. NASA and other responsible agencies are urged to study excellence in space macromanagement, including the necessary multidisciplinary skills. Two recommended targets are the application of general living systems theory and macromanagement concepts for space stations in the 1990s.

    Full Text Available This article studies the latest trends observed in the area of contradictory relations between countries with regard to international trade, which cause changes in the paradigm of international trade disputes. It has been found out that any state of inconsistent relations between the countries is recently characterized as a «trade war». It has been analyzed the notions of «dispute», «conflict», «war» according to international regulatory documents and determined the applicability of these terms depending on a number of criteria. It has been studied the evolution of the objects of international trade disputes since the time of ancient Greece until today, and new trends based on this have been revealed with regard to use of trade policy instruments that cause disputes between countries. Several specific examples of international trade disputes and causes of their occurrence have been considered. A quantitative analysis of international trade disputes in general and in relations between the leading countries in terms of a number of the trade disputes in which they were involved has been performed.

    Recent results from the Planck satellite combined with earlier observations from WMAP, ACT, SPT and other experiments eliminate a wide spectrum of more complex inflationary models and favor models with a single scalar field, as reported by the Planck Collaboration. More important, though, is that all the simplest inflaton models are disfavored statistically relative to those with plateau-like potentials. We discuss how a restriction to plateau-like models has three independent serious drawbacks: it exacerbates both the initial conditions problem and the multiverse-unpredictability problem and it creates a new difficulty that we call the inflationary “unlikeliness problem.” Finally, we comment on problems reconciling inflation with a standard model Higgs, as suggested by recent LHC results. In sum, we find that recent experimental data disfavors all the best-motivated inflationary scenarios and introduces new, serious difficulties that cut to the core of the inflationary paradigm. Forthcoming searches for B-modes, non-Gaussianity and new particles should be decisive.

    Full Text Available In plant-based medical systems, bitter tasting plants play a key role in managing dyspepsia. Yet when it comes to defining their mechanism of activity, herbalists and pharmacologists are split between two theories: one involves cephalic elicited vagal responses while the other comprises purely local responses. Recent studies indicate that bitters elicit a range of cephalic responses which alter postprandial gastric phase haemodynamics. Caffeine and regular coffee (Coffea arabica semen, L. increase heart rate whereas gentian (Gentiana lutea radix, L. and wormwood (Artemisia absinthium herba L. increase tonus in the vascular resistance vessels. Following meals increased cardiac activity acts to support postprandial hyperaemia and maintain systemic blood pressure. The increased vascular tonus acts in parallel with the increased cardiac activity and in normal adults this additional pressor effect results in a reduced cardiac workload. The vascular response is a sympathetic reflex, evident after 5 minutes and dose dependent. Thus gentian and wormwood elicit cephalic responses which facilitate rather than stimulate digestive activity when postprandial hyperaemia is inadequate. Encapsulated caffeine elicits cardiovascular responses indicating that gastrointestinal bitter receptors are functionally active in humans. However, neither encapsulated gentian nor wormwood elicited cardiovascular responses during the gastric phase. These findings provide the platform for a new evidence-based paradigm.

    Lamanna, Lenore; Moran, Patricia E

    Diverticular disease includes diverticulosis, which are sac protrusions of the intestinal mucosa, and diverticulitis, inflammation of the diverticula. Diverticular disease is listed as one of the top 10 leading physician diagnoses for gastrointestinal disorders in outpatient clinic visits in the United States. There are several classifications of diverticular disease ranging from asymptomatic diverticulosis to diverticulitis with complications. Several theories are linked to the development of diverticula which includes the physiology of the colon itself, collagen cross-linking, and recently challenged, low-fiber intake. The differential diagnoses of lower abdominal pain in addition to diverticular disease have overlapping signs and symptoms, which can make a diagnosis challenging. Identification of the distinct signs and symptoms of each classification will assist the practitioner in making the correct diagnosis and lead to appropriate management. The findings from recent studies have changed the paradigm of diverticular disease. The purpose of this article is to discuss traditional dogma and evolving concepts in the pathophysiology, prevention, and management of diverticular disease. Practitioners must be knowledgeable about diverticular disease for improved outcomes.

    2009-01-01

    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

  13. Revisiting cytogenetic paradigms armed with new tools

    It could be argued that most of the fundamental tenets of radiation biology were either discovered, or subsequently confirmed, by observing eukaryotic chromosomes under the microscope. These include, but are certainly not limited to, dose-response relationships with respect to intensity (dose rate/dose fractionation) and radiation quality (LET/track structure). Chromosome aberrations are exquisitely sensitive indicators of radiation damage, and provide quantitative information of biological effect on a cell-by-cell-basis. As such, they have long been a favored endpoint for theoreticians, thereby figuring prominently in the development of generalized models of radiation action. Most of these seminal contributions to radiation biology occurred over a period of time when cytogenetic techniques were, of course, less refined than today. Considering the increasing rate at which technological advances have been made available to the researcher over the past few years, a reexamination of some of the radiological principles that cytogenetics helped to found seems in order. As an example of such effort, this talk will center around improvements to the use of whole chromosome painting by FISH- principally combinatorial painting techniques like mFISH and SKY- for the purposes of examining in greater detail structural aberrations to chromosomes produced following exposure to ionizing radiations of differing quality and intensity. This and related approaches by various laboratories around the world have turned up a few surprise discoveries that do not always fit established paradigms, and which serve to sharpen arguments that have been used to buttress existing models of aberration formation

  14. Spirituality in Contemporary Paradigms: An Integrative Review

    2016-07-01

    Full Text Available Background: As two of the most prominent cultural components, spirituality and religion give sense to our human values, conducts, and experiences. The spiritual dimension is one of the four significant aspects of holistic care. However, the diversity of views has resulted in different interpretations of the reality of spirituality and its origins and consequences. Aim: This study aimed to examine the available approaches and paradigms in the realm of spirituality. Method: In the present integrative review, the initial search was performed in national and international databases, including Science Direct, PubMed, Google Scholar, Scopus, Sage, Medline, Wiley, SID, MagIran, IranMedex, and IranDoc, using the keyword, "spirituality", without considering any time limits. Articles relevant to the objectives of the study were then fully reviewed. Results: Since ancient times, spirituality has been sporadically discussed in human intellectual and artistic artifacts. This concept was expanded as an independent, systematic, and conscious movement since the second half of the 19th century in Europe, USA, and Canada. The three prominent approaches to spirituality include religious, secular, and holistic health perspectives. Implications for Practice: Despite the growing interest in research on spirituality, it is difficult to reach a unanimous decision about this concept. However, it should be noted that spiritual concerns cannot be disregarded, considering the holistic perspective to humanity as the building block of holistic nursing care. Overall, every patient is a unique human being whose spiritual needs are affected by his/her cultural beliefs and values.

    2012-01-01

    The paper considers basic features of a Virtual Accelerator concept based on LEGO paradigm. This concept involves three types of components: different mathematical models for accelerator design problems, integrated beam simulation packages (i. e. COSY, MAD, OptiM and others), and a special class of virtual feedback instruments similar to real control systems (EPICS). All of these components should inter-operate for more complete analysis of control systems and increased fault tolerance. The Virtual Accelerator is an information and computing environment which provides a framework for analysis based on these components that can be combined in different ways. Corresponding distributed computing services establish interaction between mathematical models and low level control system. The general idea of the software implementation is based on the Service-Oriented Architecture (SOA) that allows using cloud computing technology and enables remote access to the information and computing resources. The Virtual Accelerator allows a designer to combine powerful instruments for modeling beam dynamics in a friendly way including both self-developed and well-known packages. In the scope of this concept the following is also proposed: the control system identification, analysis and result verification, visualization as well as virtual feedback for beam line operation. The architecture of the Virtual Accelerator system itself and results of beam dynamics studies are presented. (authors)

    Full Text Available The article is an introduction to the issues and results of a new trend in interdisciplinary research, which is integrated reporting. „Violated balance”, characteristic of contemporary global economy, forces us to seek solutions oriented to symbiosis between economic, social and environmental progress, which is the basis for fundamental changes in mental models that determine the way the economic organization oper-ates. On the basis of literature studies, as well as management (of innovation, knowledge, etc. science studies and research on changes in legal regulations of accounting, one can venture to say that the change in accounting paradigms is an innovation which stems from legal requirements. Legislation stimulates conceptuality, including information management, standardization of accounting, etc. Innovation theory refers to technological, organizational and market changes, so a question ariseswhether this theory can be applied to accounting practices as well? In this way an idea emerged for inves-tigating the question if the implementation of legal regulations such as International Financial Reporting Standards (IFRS or the standards of the Global Reporting Initiative (GRI is a manifestation of the inno-vation theory in the development of accounting systems, especially in reporting.

  18. Citizen utilities: The emerging power paradigm

    Green, Jemma; Newman, Peter

    2017-01-01

    The emergence of citizen-based power systems in an integrated grid has been anticipated for decades. We can reveal how this is emerging in practice due to the significant uptake of solar photovoltaics (solar PV) and now battery storage in Perth, Australia. The high cost of electricity, high radiant energy levels and easy access to cheap Chinese technology, has led to dramatic buying during Perth's recent boomtown years. The traditional uni-directional power system is rapidly disrupting and this paper assesses where this may lead and what it means for the grid. Results of detailed monitoring in a solar powered house along with the impact of a battery storage system show the impact on the traditional grid is substantial but it will still be needed and must therefore adapt to the new distributed, bi-directional energy system. Surveys and price trajectories reveal how the trends to solar power storage will continue and how a citizen utility paradigm will emerge as the future grid building block using new blockchain support systems. Responses from utilities are then see to be fight, flight or innovate. - Highlights: • Citizen based power systems are emerging in Perth, Western Australia. • Solar power and battery storage systems are disrupting traditional utilities. • The grid will still have a role in the new, distributed power system. • The new system will lead to economic localism and the democratisation of power.

  19. An automated paradigm for Drosophila visual psychophysics.

    Oliver Evans

    Full Text Available BACKGROUND: Mutations that cause learning and memory defects in Drosophila melanogaster have been found to also compromise visual responsiveness and attention. A better understanding of attention-like defects in such Drosophila mutants therefore requires a more detailed characterization of visual responsiveness across a range of visual parameters. METHODOLOGY/PRINCIPAL FINDINGS: We designed an automated behavioral paradigm for efficiently dissecting visual responsiveness in Drosophila. Populations of flies walk through multiplexed serial choice mazes while being exposed to moving visuals displayed on computer monitors, and infra-red fly counters at the end of each maze automatically score the responsiveness of a strain. To test our new design, we performed a detailed comparison between wild-type flies and a learning and memory mutant, dunce(1. We first confirmed that the learning mutant dunce(1 displays increased responsiveness to a black/green moving grating compared to wild type in this new design. We then extended this result to explore responses to a wide range of psychophysical parameters for moving gratings (e.g., luminosity, contrast, spatial frequency, velocity as well as to a different stimulus, moving dots. Finally, we combined these visuals (gratings versus dots in competition to investigate how dunce(1 and wild-type flies respond to more complex and conflicting motion effects. CONCLUSIONS/SIGNIFICANCE: We found that dunce(1 responds more strongly than wild type to high contrast and highly structured motion. This effect was found for simple gratings, dots, and combinations of both stimuli presented in competition.

  20. Current treatment paradigms in rheumatoid arthritis.

    Science.gov (United States)

    Fries, J F

    2000-06-01

    Rheumatoid arthritis (RA) has traditionally been treated using the pyramid approach, in which non-steroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment and disease-modifying anti-rheumatic drugs (DMARDs) are introduced relatively late in the disease. This approach is no longer valid. Previously regarded as a benign disease, RA is now recognized as causing substantial morbidity and mortality, as do the NSAIDs used in treatment. DMARDs are more effective in controlling the pain and disability of RA than NSAIDs, and are often no more toxic. The current treatment paradigm emphasizes early, consistent use of DMARDs. A 'sawtooth' strategy of DMARD use has been proposed, in which a rising but low level of disability triggers a change in therapy. Determining the most clinically useful DMARD combinations and the optimal sequence of DMARD use requires effectiveness studies, Bayesian approaches and analyses of long-term outcomes. Such approaches will allow optimization of multiple drug therapies in RA, and should substantially improve the long-term outcome for many patients.

    Raymond, Carol; Russell, Christopher; Mittlefehldt, David

    2014-05-01

    While confirming the paradigm of Vesta as the parent body of the HED meteorites, measurements by Dawn have discovered many unexpected aspects of the vestan surface. First, an olivine layer was not found in the bottom of the large basin near the south pole of Vesta where excavation of the mantle was thought to have occurred. In fact, while patches of olivine have been found in the north, it is rare on the surface. Secondly, while Vesta has little gravity and appears to have completely differentiated, it is not completely dry. Morphological evidence from the walls and floors of some craters suggest transient fluid flows and pits formed by devolatization, implying a substantial amount of accessible water. The question is, did this water derive from internal or external sources? Thirdly, transport of material to the surface of Vesta from elsewhere in the asteroid belt appears as dark material buried near the top of the regolith of Vesta. This may have arrived in a single large impact and been spread around the surface and buried, later to be re-excavated. However, this is not the only scenario possible for the source of this material. Meteoritical evidence from howardites shows that debris from multiple types of impactors are present in the vestan regolith. In short, Dawn's observations of Vesta have been both reassuring but unsettling at the same time.

  3. Susceptibility to mountain hazards in Austria - paradigms of vulnerability revisited

    Science.gov (United States)

    Fuchs, Sven

    2010-05-01

    The concept of vulnerability is pillared by multiple disciplinary theories underpinning either a technical or a social origin of the concept and resulting in a range of paradigms for either a qualitative or quantitative assessment of vulnerability. However, efforts to reduce susceptibility to hazards and to create disaster-resilient communities require intersections among these theories, since human activity cannot be seen independently from the environmental setting. Acknowledging different roots of disciplinary paradigms, issues determining structural, economic, institutional and social vulnerability are discussed with respect to mountain hazards in Austria. The underlying idea of taking such an integrative viewpoint was the cognition that human action in mountain environments affects the state of vulnerability, and the state of vulnerability in turn shapes the possibilities of human action. It is argued that structural vulnerability as originator results in considerable economic vulnerability, generated by the institutional settings of dealing with natural hazards and shaped by the overall societal framework. Hence, the vulnerability of a specific location and within a considered point of time is triggered by the hazardous event and the related physical susceptibility of structures, such as buildings located on a torrent fan. Depending on the specific institutional settings, economic vulnerability of individuals or of the society results, above all with respect to imperfect loss compensation mechanisms in the areas under investigation. While this potential for harm can be addressed as social vulnerability, the concept of institutional vulnerability has been developed with respect to the overall political settings of governmental risk management. As a result, the concept of vulnerability, as being used in natural sciences, can be extended by integration of possible reasons why such physical susceptibility of structures exists, and by integration of compensation

    There is a significant lack of uniform agreement regarding nomenclature for benign vocal fold lesions (BVFLs). This confusion results in difficulty for clinicians communicating with their patients and with each other. In addition, BVFL research and comparison of treatment methods are hampered by the lack of a detailed and uniform BVFL nomenclature. Clinical consensus conferences were held to develop an initial BVFL nomenclature paradigm. Perceptual video analysis was performed to validate the stroboscopy component of the paradigm. The culmination of the consensus conferences and the video-perceptual analysis was used to evaluate the BVFL nomenclature paradigm using a retrospective review of patients with BVFL. An initial BVFL nomenclature paradigm was proposed utilizing detailed definitions relating to vocal fold lesion morphology, stroboscopy, response to voice therapy and intraoperative findings. Video-perceptual analysis of stroboscopy demonstrated that the proposed binary stroboscopy system used in the BVFL nomenclature paradigm was valid and widely applicable. Retrospective review of 45 patients with BVFL followed to the conclusion of treatment demonstrated that slight modifications of the initial BVFL nomenclature paradigm were required. With the modified BVFL nomenclature paradigm, 96% of the patients fit into the predicted pattern and definitions of the BVFL nomenclature system. This study has validated a multidimensional BVFL nomenclature paradigm. This vocal fold nomenclature paradigm includes nine distinct vocal fold lesions: vocal fold nodules, vocal fold polyp, pseudocyst, vocal fold cyst (subepithelial or ligament), nonspecific vocal fold lesion, vocal fold fibrous mass (subepithelial or ligament), and reactive lesion.

    Highlights: • DAS was developed through an innovative approach towards literature mining and technological paradigm theory. • A novel concept of biofuel feedstock development paradigm (BFDP) is proposed. • The biofuel production diffusion velocity model gives predictions for the future. • Soft path appears to be the driving force for the new paradigm shift. • An integrated biofuel production feedstock system is expected to play a significant role in a low-carbon sustainable future. - Abstract: Biofuels produced from renewable energy biomass are playing a more significant role because of the environmental problems resulting from the use of fossil fuels. However, a major problem with biofuel production is that despite the range of feedstock that can be used, raw material availability varies considerably. By combining a series of theories and methods, the research objective of this study is to determine the current developments and the future trends in biofuel feedstock. By combining technological paradigm theory with literature mining, it was found that biofuel feedstock production development followed a three-stage trajectory, which was in accordance with the traditional technological paradigm – the S-curve. This new curve can be divided into BFDP (biofuel feedstock development paradigm) competition, BFDP diffusion, and BFDP shift. The biofuel production diffusion velocity model showed that there has been constant growth from 2000, with the growth rate reaching a peak in 2008, after which time it began to drop. Biofuel production worldwide is expected to remain unchanged until 2030 when a paradigm shift is expected. This study also illustrates the results of our innovative procedure – a combination of the data analysis system and the technological paradigm theory – for the present biofuel feedstock soft path that will lead to this paradigm shift, with integrated biofuel production feedstock systems expected to be a significant new trend.

    Full Text Available Bright gamma-ray burst (GRB 110731A was simultaneously observed by Fermi and Swift observatories, with a follow up optical observation which inferred the redshift of z = 2.83. Thus, available data are spanning from optical to high energy (GeV emission. We analyze these data within the induced gravitational collapse (IGC paradigm, recently introduced to explain temporal coincidence of some long GRBs with type Ic supernovae. The case of binary-driven hypcrnova (BdHN assumes a close system, which starts as an evolved core - neutron star binary. After the core-collapse event, the new NS - black hole system is formed, emitting the GRB in the process. We performed the time-resolved and time-integrated analysis of the Fermi data. Preliminary results gave isotropic energy Eiso = 6.05 × 1053 erg and the total P-GRB energy of Ep–GRB = 3.7 × 1052 erg. At transparency point we found a Lorentz factor Γ ~ 2.17 × 103 laboratory radius of 8.33 x 1013 cm, P-GRB observed temperature of 168 keV and a baryon load B = 4.35 × 10-4. Simulated light-curve and prompt emission spectra showed the average circum burst medium density to be n ~ 0.03 particles per cm3. We reproduced the X-ray light-curve within the rest-frame of the source, finding the common late power-law behavior, with α = –1.22. Considering these results, we interpret GRB 110731A as a member of a BdHNe group.

    In the last years new evidence has accumulated on nonalcoholic fatty liver disease (NAFLD) challenging the paradigms that had been holding the scene over the previous 30 years. NAFLD has such an epidemic prevalence as to make it impossible to screen general population looking for NAFLD cases. Conversely, focusing on those cohorts of individuals exposed to the highest risk of NAFLD could be a more rational approach. NAFLD, which can be diagnosed with either non-invasive strategies or through liver biopsy, is a pathogenically complex and clinically heterogeneous disease. The existence of metabolic as opposed to genetic-associated disease, notably including ”lean NAFLD” has recently been recognized. Moreover, NAFLD is a systemic condition, featuring metabolic, cardiovascular and (hepatic/extra-hepatic) cancer risk. Among the clinico-laboratory features of NAFLD we discuss hyperuricemia, insulin resistance, atherosclerosis, gallstones, psoriasis and selected endocrine derangements. NAFLD is a precursor of type 2 diabetes (T2D) and metabolic syndrome and progressive liver disease develops in T2D patients in whom the course of disease is worsened by NAFLD. Finally, lifestyle changes and drug treatment options to be implemented in the individual patient are also critically discussed. In conclusion, this review emphasizes the new concepts on clinical and pathogenic heterogeneity of NAFLD, a systemic disorder with a multifactorial pathogenesis and protean clinical manifestations. It is highly prevalent in certain cohorts of individuals who are thus potentially amenable to selective screening strategies, intensive follow-up schedules for early identification of liver-related and extrahepatic complications and in whom earlier and more aggressive treatment schedules should be carried out whenever possible.

  8. Cooperate! A paradigm shift for health equity.

    Chang, Wei-Ching; Fraser, Joy H

    2017-02-21

    The role of competition and cooperation in relation to the goal of health equity is examined in this paper. The authors explain why the win-lose mentality associated with avoidable competition is ethically questionable and less effective than cooperation in achieving positive outcomes, particularly as it relates to health and health equity. Competition, which differentiates winners from losers, often with the winner-takes-all reward system, inevitably leads to a few winners and many losers, resulting in social inequality, which, in turn, engenders and perpetuates health inequity.Competitive market-driven approaches to healthcare-brought about by capitalism, neo-liberalization, and globalization, based primarily on a competitive framework-are shown to have contributed to growing inequities with respect to the social determinants of health, and have undermined equal opportunity to access health care and achieve health equity. It is possible to redistribute income and wealth to reduce social inequality, but globalization poses increasing challenges to policy makers. John Stuart Mill provided a passionate, philosophical defense of cooperatives, followed by Karl Polanyi who offered an insightful critique of both state socialism and especially the self-regulating market, thereby opening up the cooperative way of shaping the future. We cite Hannah Arendt's "the banality of evil" to characterize the tragic concept of "ethical fading" witnessed in business and everyday life all over the world, often committed (without thinking and reflecting) by ordinary people under competitive pressures.To promote equity in health for all, we recommend the adoption of a radically new cooperation paradigm, applied whenever possible, to everything in our daily lives.

  9. Autonomous vehicles: from paradigms to technology

    Mobility is a basic necessity of contemporary society and it is a key factor in global economic development. The basic requirements for the transport of people and goods are: safety and duration of travel, but also a number of additional criteria are very important: energy saving, pollution, passenger comfort. Due to advances in hardware and software, automation has penetrated massively in transport systems both on infrastructure and on vehicles, but man is still the key element in vehicle driving. However, the classic concept of ‘human-in-the-loop’ in terms of ‘hands on’ in driving the cars is competing aside from the self-driving startups working towards so-called ‘Level 4 autonomy’, which is defined as “a self-driving system that does not requires human intervention in most scenarios”. In this paper, a conceptual synthesis of the autonomous vehicle issue is made in connection with the artificial intelligence paradigm. It presents a classification of the tasks that take place during the driving of the vehicle and its modeling from the perspective of traditional control engineering and artificial intelligence. The issue of autonomous vehicle management is addressed on three levels: navigation, movement in traffic, respectively effective maneuver and vehicle dynamics control. Each level is then described in terms of specific tasks, such as: route selection, planning and reconfiguration, recognition of traffic signs and reaction to signaling and traffic events, as well as control of effective speed, distance and direction. The approach will lead to a better understanding of the way technology is moving when talking about autonomous cars, smart/intelligent cars or intelligent transport systems. Keywords: self-driving vehicle, artificial intelligence, deep learning, intelligent transport systems.

    Mental health problems are serious health concerns that affect women across diverse settings internationally. Knowledge of this population historically has been informed by research using a positivist approach. This article is a critical examination of contemporary paradigms for research related to women's mental health. We begin the article with an introduction to women's mental health, followed by an overview of the postpositivist, critical theory, and constructivist paradigms. We then present a critical examination of the benefits and limitations of these paradigms in relation to the study of women's mental health. We conclude with implications for research and practice.

    The success of hydrodynamics in high energy heavy-ion collisions leads to a flow paradigm, to understand the observed features of harmonic flow in terms of the medium collective expansion with respect to initial state geometrical properties. In this review, we present some essential ingredients in the flow paradigm, including the hydrodynamic modeling, the characterization of initial state geometry and the medium response relations. The extension of the flow paradigm to small colliding systems is also discussed. Supported by Natural Sciences and Engineering Research Council of Canada

    We describe a framework for model-based analysis and test case generation in the context of a heterogeneous model-based development paradigm that uses and combines Math- Works and UML 2.0 models and the associated code generation tools. This paradigm poses novel challenges to analysis and test case generation that, to the best of our knowledge, have not been addressed before. The framework is based on a common intermediate representation for different modeling formalisms and leverages and extends model checking and symbolic execution tools for model analysis and test case generation, respectively. We discuss the application of our framework to software models for a NASA flight mission.

  19. Cosmological horizons as new examples of the membrane paradigm

    International Nuclear Information System (INIS)

    Wang, Tower

    2015-01-01

    In this paper we aim to provide new examples of the application and the generality of the membrane paradigm. The membrane paradigm is a formalism for studying the event horizon of black holes. After analyzing it with some technical details and realizing it in the Reissner–Nordström black hole, we apply the paradigm to cosmological horizons, first to the pure de Sitter horizon, and then to the trapping horizon of the Friedmann–Lemaître–Robertson–Walker Universe. In the latter case, the cosmological stretched horizon is oblique, thus the running of the renormalization parameter is nonzero in the timelike direction and gives a correction to the membrane pressure. In this paradigm, the cosmological equations come from continuity equations of the membrane fluid and the bulk fluid respectively. (paper)

  20. Paradigm shift in psychiatry: what may it involve?

    Science.gov (United States)

    Valent, Paul

    2018-02-01

    This study aims to examine the potential nature of an ongoing paradigm shift in psychiatry that has been suggested to be occurring. New findings in traumatology and neuroscience do form a potential platform for a paradigm shift. Prior conflicting paradigms are suggested to be due to biases arising from mental structures themselves. A new wholist perspective is proposed, which makes sense of and incorporates previous paradigms, and coheres recent understanding of right- and left-brain functioning and biopsychosocial traumatic processes and their ramifications. The perspective makes sense of the great variety of post-traumatic manifestations ranging from somatic to meaning-making dysfunctions. The wholist perspective may well be an important step in solidifying a fresh paradigmatic perspective in psychiatry.

  1. The "extended mind" approach for a new paradigm of psychology.

    Science.gov (United States)

    Kono, Tetsuya

    2010-12-01

    In this paper, I would like to propose the idea of "extended mind" for a new paradigm of psychology. Kohler (Integrative Psychology & Behavioral Science 44:39-57, 2010) correctly pointed out the serious problems of the machine paradigm, and proposed the "organic" view as a new paradigm. But the term "organic" signifying the processes inside the body, is inadequate to express the characteristic of human mind. The recent philosophy of mind suggests that the mind is realized neither only in the brain nor only in the body, but in the whole system of brain-body-environment, namely, in the "extended mind". The characteristic of human mind resides in the interaction with the mediating tools, artifacts, and the humanized environment. We should propose an "extended mind approach" or an "ecological approach to humanized environment" as a new paradigm for a psychology.

    Debate about the relationship between quantitative and qualitative paradigms is often muddled and confusing and the clutter of terms and arguments has resulted in the concepts becoming obscure and unrecognizable. In this study we conducted content analysis regarding evaluation methods of qualitative healthcare research. We extracted descriptions on four types of evaluation paradigm (validity/credibility, reliability/credibility, objectivity/confirmability, and generalizability/transferability), and classified them into subcategories. In quantitative research, there has been many evaluation methods based on qualitative paradigms, and vice versa. Thus, it might not be useful to consider evaluation methods of qualitative paradigm are isolated from those of quantitative methods. Choosing practical evaluation methods based on the situation and prior conditions of each study is an important approach for researchers.

    2015-09-01

    This article is devoted to the question which paradigms currently determine psychotherapy and psychotherapy research, and if there are indicators of paradigm changes in this field. The question of the efficacy and effectiveness (including the effectiveness of a transfer of psychotherapeutic knowledge to service) is specifically focussed as well as the question of the central therapeutic factors and the significance of the person of the therapist. It is argued that there are really some signals of a paradigm switch, with a turn away from controlled outcome research, representing only a minor part of patients in need of psychotherapy, towards a more specific process oriented research, also considering differential effects of the therapist. The most prominent indicator of a paradigm change is reflected by an increasing influence of patient oriented psychotherapy research which - consequently - should also be supported by the insurances as well as the funding organisations. © Georg Thieme Verlag KG Stuttgart · New York.

    In this synthesis paper addressing hydrologic scaling and similarity, we posit that roadblocks in the search for universal laws of hydrology are hindered by our focus on computational simulation (the third paradigm), and assert that it is time for hydrology to embrace a fourth paradigm of data-intensive science. Advances in information-based hydrologic science, coupled with an explosion of hydrologic data and advances in parameter estimation and modelling, have laid the foundation for a data-driven framework for scrutinizing hydrological scaling and similarity hypotheses. We summarize important scaling and similarity concepts (hypotheses) that require testing, describe a mutual information framework for testing these hypotheses, describe boundary condition, state flux, and parameter data requirements across scales to support testing these hypotheses, and discuss some challenges to overcome while pursuing the fourth hydrological paradigm. We call upon the hydrologic sciences community to develop a focused effort towards adopting the fourth paradigm and apply this to outstanding challenges in scaling and similarity.

    Every examination of disability among children must first grapple with definition of disability. The challenges to identifying disability among children involve not only determining the appropriate paradigm for defining disability, but also applying that paradigm to children in a meaningful way. This discussion of the prevalence of disability among children starts by examining the various paradigms utilized to identify disability and how they are interpreted when applied to children. Estimates of the prevalence of childhood disability, under different definitions of disability are presented. The goal of the discussion is to illustrate the sensitivity of the estimates of disability prevalence to the particular definition and data set used. Finally, the potential influence of the choice of paradigm on further measurement and service delivery is outlined.

    Pasluosta, Cristian; Kiele, Patrick; Stieglitz, Thomas

    2018-04-01

    The somatosensory system contributes substantially to the integration of multiple sensor modalities into perception. Tactile sensations, proprioception and even temperature perception are integrated to perceive embodiment of our limbs. Damage of somatosensory networks can severely affect the execution of daily life activities. Peripheral injuries are optimally corrected via direct interfacing of the peripheral nerves. Recent advances in implantable devices, stimulation paradigms, and biomimetic sensors enabled the restoration of natural sensations after amputation of the limb. The refinement of stimulation patterns to deliver natural feedback that can be interpreted intuitively such to prescind from long-learning sessions is crucial to function restoration. For this review, we collected state-of-the-art knowledge on the evolution of stimulation paradigms from single fiber stimulation to the eliciting of multisensory sensations. Data from the literature are structured into six sections: (a) physiology of the somatosensory system; (b) stimulation of single fibers; (c) restoral of multisensory percepts; (d) closure of the control loop in hand prostheses; (e) sensory restoration and the sense of embodiment, and (f) methodologies to assess stimulation outcomes. Full functional recovery demands further research on multisensory integration and brain plasticity, which will bring new paradigms for intuitive sensory feedback in the next generation of limb prostheses.

    The membrane paradigm approach adopts a timelike surface, stretched out off the null event horizon, to study several important black hole properties. We use this powerful tool to give a direct derivation of the black hole mass formula in the static and stationary cases without and with electric field. Since here the membrane is a self-gravitating material system, we go beyond the usual applicability on test particles and test fields of the paradigm.

  17. Toward New-Generation Intelligent Manufacturing

    Directory of Open Access Journals (Sweden)

    Ji Zhou

    2018-02-01

    Full Text Available Intelligent manufacturing is a general concept that is under continuous development. It can be categorized into three basic paradigms: digital manufacturing, digital-networked manufacturing, and new-generation intelligent manufacturing. New-generation intelligent manufacturing represents an in-depth integration of new-generation artificial intelligence (AI technology and advanced manufacturing technology. It runs through every link in the full life-cycle of design, production, product, and service. The concept also relates to the optimization and integration of corresponding systems; the continuous improvement of enterprises’ product quality, performance, and service levels; and reduction in resources consumption. New-generation intelligent manufacturing acts as the core driving force of the new industrial revolution and will continue to be the main pathway for the transformation and upgrading of the manufacturing industry in the decades to come. Human-cyber-physical systems (HCPSs reveal the technological mechanisms of new-generation intelligent manufacturing and can effectively guide related theoretical research and engineering practice. Given the sequential development, cross interaction, and iterative upgrading characteristics of the three basic paradigms of intelligent manufacturing, a technology roadmap for “parallel promotion and integrated development” should be developed in order to drive forward the intelligent transformation of the manufacturing industry in China.

  18. The string-pulling paradigm in comparative psychology.

    Science.gov (United States)

    Jacobs, Ivo F; Osvath, Mathias

    2015-05-01

    String pulling is one of the most widely used paradigms in comparative psychology. First documented 2 millennia ago, it has been a well-established scientific paradigm for a century. More than 160 bird and mammal species have been tested in over 200 studies with countless methodological variations. The paradigm can be used to address a wide variety of issues on animal cognition; for example, what animals understand about contact and connection as well as whether they rely on perceptual feedback, grasp the functionality of strings, generalize across conditions, apply their knowledge flexibly, and possess insight. Mammals are typically tested on a horizontal configuration, birds on a vertical one, making the studies difficult to compare; in particular, pulling a string vertically requires better coordination and attention. A species' performance on the paradigm is often influenced by its ecology, especially concerning whether limbs are used for foraging. Many other factors can be of importance and should be considered. The string-pulling paradigm is easy to administer, vary, and apply to investigate a wide array of cognitive abilities. Although it can be and has been used to compare species, divergent methods and unclear reporting have limited its comparative utility. With increasing research standards, the paradigm is expected to become an even more fundamental tool in comparative psychology. (c) 2015 APA, all rights reserved).

    The Poffenberger paradigm is a simple perception task that is used to estimate the speed of information transfer between the two hemispheres, the so-called interhemispheric transfer time (IHTT). Although the original paradigm is a behavioral task, it can be combined with electroencephalography (EEG) to assess the underlying neurophysiological processes during task execution. While older studies have supported the validity of both paradigms for investigating interhemispheric interactions, their long-term reliability has not been assessed systematically before. The present study aims to fill this gap by determining both internal consistency and long-term test-retest reliability of IHTTs produced by using the two different versions of the Poffenberger paradigm in a sample of 26 healthy subjects. The results show high reliability for the EEG Poffenberger paradigm. In contrast, reliability measures for the behavioral Poffenberger paradigm were low. Hence, our results indicate that electrophysiological measures of interhemispheric transfer are more reliable than behavioral measures; the later should be used with caution in research investigating inter-individual differences of neurocognitive measures.

    The amount of scientific literature on (Geographic) Object-based Image Analysis - GEOBIA has been and still is sharply increasing. These approaches to analysing imagery have antecedents in earlier research on image segmentation and use GIS-like spatial analysis within classification and feature extraction approaches. This article investigates these development and its implications and asks whether or not this is a new paradigm in remote sensing and Geographic Information Science (GIScience). We first discuss several limitations of prevailing per-pixel methods when applied to high resolution images. Then we explore the paradigm concept developed by Kuhn (1962) and discuss whether GEOBIA can be regarded as a paradigm according to this definition. We crystallize core concepts of GEOBIA, including the role of objects, of ontologies and the multiplicity of scales and we discuss how these conceptual developments support important methods in remote sensing such as change detection and accuracy assessment. The ramifications of the different theoretical foundations between the ' per-pixel paradigm ' and GEOBIA are analysed, as are some of the challenges along this path from pixels, to objects, to geo-intelligence. Based on several paradigm indications as defined by Kuhn and based on an analysis of peer-reviewed scientific literature we conclude that GEOBIA is a new and evolving paradigm.

  1. New radiobiological, radiation risk and radiation protection paradigms

    International Nuclear Information System (INIS)

    Goodhead, Dudley T.

    2010-01-01

    The long-standing conventional paradigm for radiobiology has formed a logical basis for the standard paradigm for radiation risk of cancer and heritable effects and, from these paradigms, has developed the internationally applied system for radiation protection, but with many simplifications, assumptions and generalizations. A variety of additional radiobiological phenomena that do not conform to the standard paradigm for radiobiology may have potential implications for radiation risk and radiation protection. It is suggested, however, that the current state of knowledge is still insufficient for these phenomena, individually or collectively, to be formulated systematically into a new paradigm for radiobiology. Additionally, there is at present lack of direct evidence of their relevance to risk for human health, despite attractive hypotheses as to how they might be involved. Finally, it remains to be shown how incorporation of such phenomena into the paradigm for radiation protection would provide sufficient added value to offset disruption to the present widely applied system. Further research should aim for better mechanistic understanding of processes such as radiation-induced genomic instability (for all radiation types) and bystander effects (particularly for low-fluence high-LET particles) and also priority should be given to confirmation, or negation, of the relevance of the processes to human health risks from radiation.

  2. A knowledge-centered paradigm for operations and design

    A paradigm premised on the reactor design basis and on its systems, structures, and components also governs nuclear power plant operations. This machine-centered paradigm emphasizes a functional and discipline-based division of responsibilities, which can create hierarchical 'silos' and 'stovepipes' inhibiting the development and lateral exchange of knowledge about safety-critical system interactions. A knowledge-centered paradigm instead encourages the timely development, analysis, and exchange of information about system conditions and their likely consequences. This new paradigm puts operational focus on the importance of operating experience, informative root cause analyses, effective corrective actions, and cross-discipline exchange and cooperation. Although the knowledge-centered paradigm is already central to three main strategies of risk reduction, it is less likely to be recognized as such in terms of priorities, resources, and training: configuration control, control room operations, and root cause analysis. To maintain the capacity for safe shutdown and to preserve public trust, the knowledge-centered paradigm places as high a priority on interactions of safety-critical knowledge as it does on interactions of safety-critical systems, structures, and components.

  3. Tuberculosis as a three-act play: A new paradigm for the pathogenesis of pulmonary tuberculosis.

    Science.gov (United States)

    Hunter, Robert L

    2016-03-01

    Lack of access to human tissues with untreated tuberculosis (TB) has forced generations of researchers to use animal models and to adopt a paradigm that granulomas are the characteristic lesion of both primary and post primary TB. An extended search of studies of human lung tissues failed to find any reports that support this paradigm. We found scores of publications from gross pathology in 1804 through high resolution CT scans in 2015 that identify obstructive lobular pneumonia, not granulomas, as the characteristic lesion of developing post-primary TB. This paper reviews this literature together with other relevant observations to formulate a new paradigm of TB with three distinct stages: a three-act play. First, primary TB, a war of attrition, begins with infection that spreads via lymphatics and blood stream before inducing systemic immunity that contains and controls the organisms within granulomas. Second, post-primary TB, a sneak attack, develops during latent TB as an asymptomatic obstructive lobular pneumonia in persons with effective systemic immunity. It is a paucibacillary process with no granulomas that spreads via bronchi and accumulates mycobacterial antigens and host lipids for 1-2 years before suddenly undergoing caseous necrosis. Third, the fallout, is responsible for nearly all clinical post primary disease. It begins with caseous necrotic pneumonia that is either retained to become the focus of fibrocaseous disease or is coughed out to leave a cavity. This three-stage paradigm suggests testable hypotheses and plausible answers to long standing questions of immunity to TB. Copyright © 2015 The Author. Published by Elsevier Ltd..

  4. Metabolic engineering: the ultimate paradigm for continuous pharmaceutical manufacturing.

    Yadav, Vikramaditya G; Stephanopoulos, Gregory

    2014-07-01

    Research and development (R&D) expenditures by pharmaceutical companies doubled over the past decade, yet candidate attrition rates and development times rose markedly during this period. Understandably, companies have begun downsizing their pipelines and diverting investments away from R&D in favor of manufacturing. It is estimated that transitioning to continuous manufacturing could enable companies to compete for a share in emerging markets. Accordingly, the model for continuous manufacturing that has emerged commences with the conversion of late-stage intermediates into the active pharmaceutical ingredient (API) in a series of continuous flow reactors, followed by continuous solid processing to form finished tablets. The use of flow reactions for API synthesis will certainly generate purer products at higher yields in shorter times compared to equivalent batch reactions. However, transitioning from batch to flow configuration simply alleviates transport limitations within the reaction milieu. As the catalogue of reactions used in flow syntheses is a subset of batch-based chemistries, molecules such as natural products will continue to evade drug prospectors. Also, it is uncertain whether flow synthesis can deliver improvements in the atom and energy economies of API production at the scales that would achieve the levels of revenue growth targeted by companies. Instead, it is argued that implementing metabolic engineering for the production of oxidized scaffolds as gateway molecules for flow-based addition of electrophiles is a more effective and scalable strategy for accessing natural product chemical space. This new paradigm for manufacturing, with metabolic engineering as its engine, would also permit rapid optimization of production variables and allow facile scale-up from gram to ton scale to meet material requirements for clinical trials, thus recasting manufacturing as a tool for discovery. © 2014 WILEY-VCH Verlag GmbH & Co.

  5. Evolvable mathematical models: A new artificial Intelligence paradigm

    Science.gov (United States)

    Grouchy, Paul

    We develop a novel Artificial Intelligence paradigm to generate autonomously artificial agents as mathematical models of behaviour. Agent/environment inputs are mapped to agent outputs via equation trees which are evolved in a manner similar to Symbolic Regression in Genetic Programming. Equations are comprised of only the four basic mathematical operators, addition, subtraction, multiplication and division, as well as input and output variables and constants. From these operations, equations can be constructed that approximate any analytic function. These Evolvable Mathematical Models (EMMs) are tested and compared to their Artificial Neural Network (ANN) counterparts on two benchmarking tasks: the double-pole balancing without velocity information benchmark and the challenging discrete Double-T Maze experiments with homing. The results from these experiments show that EMMs are capable of solving tasks typically solved by ANNs, and that they have the ability to produce agents that demonstrate learning behaviours. To further explore the capabilities of EMMs, as well as to investigate the evolutionary origins of communication, we develop NoiseWorld, an Artificial Life simulation in which interagent communication emerges and evolves from initially noncommunicating EMM-based agents. Agents develop the capability to transmit their x and y position information over a one-dimensional channel via a complex, dialogue-based communication scheme. These evolved communication schemes are analyzed and their evolutionary trajectories examined, yielding significant insight into the emergence and subsequent evolution of cooperative communication. Evolved agents from NoiseWorld are successfully transferred onto physical robots, demonstrating the transferability of EMM-based AIs from simulation into physical reality.

    A classic paradigm in radiation biology asserts that all radiation effects on cells, tissues and organisms are due to the direct action of radiation on living tissue. Using this model, possible risks from exposure to low dose ionizing radiation (below 100 mSv) are estimated by extrapolating from data obtained after exposure to higher doses of radiation, using a linear non-threshold model (LNT model). However, the validity of using this dose-response model is controversial because evidence accumulated over the past decade has indicated that living organisms, including humans, respond differently to low dose/low dose-rate radiation than they do to high dose/high dose-rate radiation. These important responses to low dose/low dose-rate radiation are the radiation-induced adaptive response, the bystander response, low-dose hypersensitivity, and genomic instability. The mechanisms underlying these responses often involve bio-chemical and molecular signals generated in response to targeted and non-targeted events. In order to define and understand the bystander response to provide a basis for the understanding of non-targeted events and to elucidate the mechanisms involved, recent sophisticated research has been conducted with X-ray microbeams and charged heavy particle microbeams, and these studies have produced many new observations. Based on these observations, associations have been suggested to exist between the radio-adaptive and bystander responses. The present review focuses on these two phenomena, and summarizes observations supporting their existence, and discusses the linkage between them in light of recent results obtained from experiments utilizing microbeams.

    On the strength of the literature analysis and the Emilia-Romagna Region experience, we suggest a reflection on the workplace-based learning that goes beyond the analysis of the effectiveness of specific didactic methodologies and aspects related to Continuing Medical Education. Health education and training issue is viewed from a wider perspective, that integrates the three learning dimensions (formal, non formal and informal). In such a perspective the workplace-based learning becomes an essential paradigm to reshape the explicit knowledge conveyed in formal context and to emphasize informal contexts where innovation is generated.

    Laryngeal squamous cell carcinoma (LSCC) remains a highly morbid and fatal disease. Historically, it has been a model example for organ preservation and treatment stratification paradigms. Unfortunately, survival for LSCC has stagnated over the past few decades. As the era of next-generation sequencing and personalized treatment for cancer approaches, LSCC may be an ideal disease for consideration of further treatment stratification and personalization. Here, we will discuss the important history of LSCC as a model system for organ preservation, unique and potentially targetable genetic signatures of LSCC, and methods for bringing stratified, personalized treatment strategies to the 21 st century

  10. Composite paradigms in medicine: analysing Gillies' claim of reclassification of disease without paradigm shift in the case of Helicobacter pylori.

    Science.gov (United States)

    Hutton, Joseph

    2012-09-01

    Since the publication of Kuhn's The Structure of Scientific Revolutions in 1962, the notion of paradigms has shaped the way that philosophy views scientific discovery and how changes in what is regarded as empirical fact occur. This drew heavily on examples from the history of the natural sciences to support Kuhn's hypothesis. However, some argue that medicine is different from the natural sciences. Gillies has proposed another theory of how paradigms apply to medicine; that of composite paradigms. In doing so, Gillies uses the example of Helicobacter pylori and the shift from the excess-acid theory to the current bacterial-infection theory of gastric ulcers to illustrate these fundamental differences between medicine and the natural sciences. Upon analysis of Gillies' claim, it is evident that traditional Kuhnian paradigms are also composite and that the manner in which Gillies proposes disease is classified is insufficient in describing medicine. Furthermore, new local paradigms are demonstrably introduced and the change was accompanied by many of the markers of paradigmatic change including changes in worldview, resistance, incommensurability and the introduction of new questions that could not have existed under the previous paradigm. Whilst this change may not be on the scale of the Chemical revolution, it can still be considered paradigm shift. Thagard also proposes an alternate view of discovery using the case of H. pylori. This has much in common with Kuhnian paradigms but Thagard's theory offers further elucidation and refinement. This allows it to better characterise all of the associated features of discovery relevant in the case of H. pylori, thus provides a preferable tool for examination of this important recent discovery.

  18. Modular Energy-Efficient and Robust Paradigms for a Disaster-Recovery Process over Wireless Sensor Networks.

    Robust paradigms are a necessity, particularly for emerging wireless sensor network (WSN) applications. The lack of robust and efficient paradigms causes a reduction in the provision of quality of service (QoS) and additional energy consumption. In this paper, we introduce modular energy-efficient and robust paradigms that involve two archetypes: (1) the operational medium access control (O-MAC) hybrid protocol and (2) the pheromone termite (PT) model. The O-MAC protocol controls overhearing and congestion and increases the throughput, reduces the latency and extends the network lifetime. O-MAC uses an optimized data frame format that reduces the channel access time and provides faster data delivery over the medium. Furthermore, O-MAC uses a novel randomization function that avoids channel collisions. The PT model provides robust routing for single and multiple links and includes two new significant features: (1) determining the packet generation rate to avoid congestion and (2) pheromone sensitivity to determine the link capacity prior to sending the packets on each link. The state-of-the-art research in this work is based on improving both the QoS and energy efficiency. To determine the strength of O-MAC with the PT model; we have generated and simulated a disaster recovery scenario using a network simulator (ns-3.10) that monitors the activities of disaster recovery staff; hospital staff and disaster victims brought into the hospital. Moreover; the proposed paradigm can be used for general purpose applications. Finally; the QoS metrics of the O-MAC and PT paradigms are evaluated and compared with other known hybrid protocols involving the MAC and routing features. The simulation results indicate that O-MAC with PT produced better outcomes.

  20. Reexamining unconscious response priming: A liminal-prime paradigm.

    2018-03-01

    Research on the limits of unconscious processing typically relies on the subliminal-prime paradigm. However, this paradigm is limited in the issues it can address. Here, we examined the implications of using the liminal-prime paradigm, which allows comparing unconscious and conscious priming with constant stimulation. We adapted an iconic demonstration of unconscious response priming to the liminal-prime paradigm. On the one hand, temporal attention allocated to the prime and its relevance to the task increased the magnitude of response priming. On the other hand, the longer RTs associated with the dual task inherent to the paradigm resulted in response priming being underestimated, because unconscious priming effects were shorter-lived than conscious-priming effects. Nevertheless, when the impact of long RTs was alleviated by considering the fastest trials or by imposing a response deadline, conscious response priming remained considerably larger than unconscious response priming. These findings suggest that conscious perception strongly modulates response priming. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Complexity: a potential paradigm for a health promotion discipline.

    Science.gov (United States)

    Tremblay, Marie-Claude; Richard, Lucie

    2014-06-01

    Health promotion underpins a distancing from narrow, simplifying health approaches associated with the biomedical model. However, it has not yet succeeded in formally establishing its theoretical, epistemological and methodological foundations on a single paradigm. The complexity paradigm, which it has yet to broach head-on, might provide it with a disciplinary matrix in line with its implicit stances and basic values. This article seeks to establish complexity's relevance as a paradigm that can contribute to the development of a health promotion discipline. The relevance of complexity is justified primarily by its matching with several implicit epistemological and methodological/theoretical stances found in the cardinal concepts and principles of health promotion. The transcendence of ontological realism and determinism as well as receptiveness in respect of the reflexivity that complexity encompasses are congruent with the values of social justice, participation, empowerment and the concept of positive health that the field promotes. Moreover, from a methodological and theoretical standpoint, complexity assumes a holistic, contextual and transdisciplinary approach, toward which health promotion is tending through its emphasis on ecology and interdisciplinary action. In a quest to illustrate our position, developmental evaluation is presented as an example of practice stemming from a complexity paradigm that can be useful in the evaluation of health promotion initiatives. In short, we argue that it would be advantageous for health promotion to integrate this paradigm, which would provide it with a formal framework appropriate to its purposes and concerns.

  2. e-Science Paradigm for Astroparticle Physics at KISTI

    Full Text Available The Korea Institute of Science and Technology Information (KISTI has been studying the e-Science paradigm. With its successful application to particle physics, we consider the application of the paradigm to astroparticle physics. The Standard Model of particle physics is still not considered perfect even though the Higgs boson has recently been discovered. Astrophysical evidence shows that dark matter exists in the universe, hinting at new physics beyond the Standard Model. Therefore, there are efforts to search for dark matter candidates using direct detection, indirect detection, and collider detection. There are also efforts to build theoretical models for dark matter. Current astroparticle physics involves big investments in theories and computing along with experiments. The complexity of such an area of research is explained within the framework of the e-Science paradigm. The idea of the e-Science paradigm is to unify experiment, theory, and computing. The purpose is to study astroparticle physics anytime and anywhere. In this paper, an example of the application of the paradigm to astrophysics is presented.

  3. Connecting traditional sciences with the OLAP and data mining paradigms

    2003-03-01

    The paradigms of OLAP, multidimensional modeling and data mining have first emerged in the areas of market analysis and finance to address various needs of people working in these areas. Does this mean that they are useful and applicable in these areas only? Or, can they also be applicable in the other more traditional areas of science and engineering? What characterize the systems for which these paradigms are suitable? What are the goals of these paradigms? How do they relate to the traditional body of knowledge that has been developed throughout the centuries in the areas of mathematics, statistics, systems science and engineering? Where, how and to what extent can we leverage the conventional wisdom that has been accumulated in the aforementioned disciplines to develop a foundational basis for the above paradigms? The goal of this paper is to address these questions at the foundational level. We argue that the paradigms of OLAP, multidimensional modeling and data mining can also be applied successfully to complex engineering systems, such as membrane-based water/wastewater treatment plants, for example. We develop mathematically-based axiomatic definition of the concepts of 'dimension,' 'dimension level,' 'dimension hierarchy' and 'measure' using set theory and equivalence relations.

    Full Text Available The debate of method of recognition in humanities, social and nature science is one of the apprehensions of Scientists in Wisdom Domain –especially in the modern world. This apprehension, before all things was of appearing in the paradigm of methodoligical between the advocates of the paradigms of positivism with having a share of the natural science. They used to values of naturalism in social and human studies. Additionally, testing and observation and repetition are present as the main terms of recognition. In front, the difference between human studies and natural science is important for the advocates of hermeneutic paradigm. Also, they speak about the methodology of interpretation (understanding of human and social phenomenon. But, in the second half of 20th century another paradigms was established as the Critical realism. This paradigm is tried to parther from the methodoloigcal binary and has a share from the recognition of ontological positivism and epistemological hermeneutics attain to a procedure of interdisciplinary about recognition. So, on the basis of this subject, this article mentioned this question that: would the critical realism receive as the methodology in interdisciplinary? Method of the Article is postulate. This article reasoned that multilayer ontology and epistemology redounded to multilayer methodology that could build up the knowledge of interdisciplinary.

    To generate meaningful information, translational research must employ paradigms that allow extrapolation from animal models to humans. However, few studies have evaluated translational paradigms on the basis of defined validation criteria. We outline three criteria for validating translational paradigms. We then evaluate the Hebb–Williams maze paradigm (Hebb and Williams, 1946; Rabinovitch and Rosvold, 1951) on the basis of these criteria using Fragile X syndrome (FXS) as model disease. We focused on this paradigm because it allows direct comparison of humans and animals on tasks that are behaviorally equivalent (criterion #1) and because it measures spatial information processing, a cognitive domain for which FXS individuals and mice show impairments as compared to controls (criterion #2). We directly compared the performance of affected humans and mice across different experimental conditions and measures of behavior to identify which conditions produce comparable patterns of results in both species. Species differences were negligible for Mazes 2, 4, and 5 irrespective of the presence of visual cues, suggesting that these mazes could be used to measure spatial learning in both species. With regards to performance on the first trial, which reflects visuo-spatial problem solving, Mazes 5 and 9 without visual cues produced the most consistent results. We conclude that the Hebb–Williams mazes paradigm has the potential to be utilized in translational research to measure comparable cognitive functions in FXS humans and animals (criterion #3).

  7. Charting Relations between Intersectionality Theory and the Neurodiversity Paradigm

    Directory of Open Access Journals (Sweden)

    Lauren Rose Strand

    2017-06-01

    Full Text Available This essay explores central elements and applications of intersectionality theory and the neurodiversity paradigm. First, the histories and tenets of intersectionality theory and neurodiversity paradigm are provided. Then, areas are explored where each of the two approaches might further engage with the principles of the other. Finally, the essay concludes by broadly considering the efforts made by the Black Lives Matter movement and the Autistic Self Advocacy Network to bring attention to and end police violence as both networks employ and attend to elements of intersectionality and neurodiversity. The way these two networks draw on both intersectionality and neurodiversity to further their mission could be a possible site for scholars to consider in the interest of advancing dialogues between intersectionality theory and the neurodiversity paradigm. Ultimately, the essay calls for a continued exploration of the potentials for intersectionality and neurodiversity to complement and complicate one another, both in terms of theoretical development and coalition building.

  8. Conjugal conflict and violence: a review and theoretical paradigm.

    Science.gov (United States)

    1994-02-01

    Conjugal violence has been described as having multiple etiologies. The variables are so numerous that intervention and research protocols are difficult to effect. This paper proposes a paradigm that establishes conjugal conflict and violence as separate entities. According to the paradigm, conjugal conflict is viewed as "an inevitable part of human association," whereas conjugal violence is determined to be a learned behavioral tactic that is employed as a coping strategy when an individual's conflict threshold potential is exceeded. Evidence will be offered that violence is learned from family of origin and from observing what is common or accepted practice in the community. Use of this paradigm would give primacy to community education programs that advance the concept of conflict resolution through rational discourse.

  9. Convergent paradigms for visual neuroscience and dissociative identity disorder.

    Manning, Mark L; Manning, Rana L

    2009-01-01

    Although dissociative identity disorder, a condition in which multiple individuals appear to inhabit a single body, is a recognized psychiatric disorder, patients may yet encounter health professionals who declare that they simply "do not believe in multiple personalities." This article explores the proposal that resistance to the disorder represents a failure to apply an appropriate paradigm from which the disorder should be interpreted. Trauma and sociocognitive explanations of dissociative identity disorder are contrasted. The trauma hypothesis is further differentiated into paradigms in which trauma affects a defense mechanism, and one in which trauma serves to inhibit the normal integration sequence of parallel processes of the self in childhood. This latter paradigm is shown to be broadly consistent with current models of cortical processing in another system, the cortical visual system.

  10. Toward a patient-based paradigm for blood transfusion.

    Science.gov (United States)

    Farrugia, Albert; Vamvakas, Eleftherios

    2014-01-01

    The current "manufacturing paradigm" of transfusion practice has detached transfusion from the clinical environment. As an example, fresh whole blood in large-volume hemorrhage may be superior to whole blood reconstituted from multiple components. Multicomponent apheresis can overcome logistical difficulties in matching patient needs with fresh component availability and can deliver the benefits of fresh whole blood. Because of the different transfusion needs of patients in emerging economies and the vulnerability of these blood systems to emerging infections, fresh whole blood and multicomponent apheresis can better meet patient needs when compared with transplants of the "manufacturing paradigm". We propose that patient blood management, along with panels of repeat, paid, accredited apheresis and fresh whole-blood donors can be used in emerging economies to support decentralized blood services. This alternative transfusion-medicine paradigm could eventually also be adopted by established economies to focus transfusion medicine on local patient needs and to alleviate the problem of the aging volunteer donor base.

  11. Embracing the new paradigm of assessment in residency training

    DEFF Research Database (Denmark)

    Ringsted, C; Østergaard, D; Scherpbier, A

    2003-01-01

    Assessment of clinical competence is facing a paradigm shift in more than one sense. The shift relates to test content, which increasingly covers a broader spectrum of competences than mere medical expertise, and to test methods, with an increasing focus on testing performance in realistic settings....... Also there is a shift in the concept of assessment in that instruction and assessment are no longer seen as being separate in time and purpose, but as integral parts of the learning process. The nature of the new paradigm for assessment is well described but the challenge to programme directors...... is to specify the evaluation situations and develop appropriate methods. This paper describes the intrinsic rational validation process in outlining an assessment programme for first-year anaesthesiology residency training according to the new paradigm. The applicability to other residency programmes and higher...

  12. Cryptocurrency Networks: A New P2P Paradigm

    Sergi Delgado-Segura

    2018-01-01

    Full Text Available P2P networks are the mechanism used by cryptocurrencies to disseminate system information while keeping the whole system as much decentralized as possible. Cryptocurrency P2P networks have new characteristics that propose new challenges and avoid some problems of existing P2P networks. By characterizing the most relevant cryptocurrency network, Bitcoin, we provide details on different properties of cryptocurrency networks and their similarities and differences with standard P2P network paradigms. Our study allows us to conclude that cryptocurrency networks present a new paradigm of P2P networks due to the mechanisms they use to achieve high resilience and security. With this new paradigm, interesting research lines can be further developed, both in the focused field of P2P cryptocurrency networks and also when such networks are combined with other distributed scenarios.

  13. Language-learning disabilities: Paradigms for the nineties.

    Science.gov (United States)

    Wiig, E H

    1991-01-01

    We are beginning a decade, during which many traditional paradigms in education, special education, and speech-language pathology will undergo change. Among paradigms considered promising for speech-language pathology in the schools are collaborative language intervention and strategy training for language and communication. This presentation introduces management models for developing a collaborative language intervention process, among them the Deming Management Method for Total Quality (TQ) (Deming 1986). Implementation models for language assessment and IEP planning and multicultural issues are also introduced (Damico and Nye 1990; Secord and Wiig in press). While attention to processes involved in developing and implementing collaborative language intervention is paramount, content should not be neglected. To this end, strategy training for language and communication is introduced as a viable paradigm. Macro- and micro-level process models for strategy training are featured and general issues are discussed (Ellis, Deshler, and Schumaker 1989; Swanson 1989; Wiig 1989).

  14. Investigating saccade programming in the praying mantis Tenodera aridifolia using distracter interference paradigms.

    Science.gov (United States)

    Yamawaki, Yoshifumi

    2006-10-01

    To investigate the saccadic system in the mantis, I applied distracter interference paradigms. These involved presenting the mantis with a fixation target and one or several distracters supposed to affect saccades towards the target. When a single target was presented, a medium-sized target located in its lower visual field elicited higher rates of saccade response. This preference for target size and position was also observed when a target and a distracter were presented simultaneously. That is, the mantis chose and fixated the target rather than a distracter that was much smaller or larger than the target, or was located above the target. Furthermore, the mantis' preference was not affected by increasing the number of distracters. However, the presence of the distracter decreased the occurrence rate of saccade and increased the response time to saccade. I conclude that distracter interference paradigms are an effective way of investigating the visual processing underlying saccade generation in the mantis. Possible mechanisms of saccade generation in the mantis are discussed.

  15. Crustal layering, simplicity, and the oil industry: The alteration of an epistemic paradigm by a commercial environment

    Science.gov (United States)

    Anduaga, Aitor

    This paper proposes that the gradual alteration of the predominant epistemic paradigm in crustal seismology in the interwar period-namely, simplicity-came about because of the strong influence of a particular commercial environment, i.e. the oil industry. I begin by demonstrating the interwar predominance of Jeffreys' 'simplicity postulate' and his probabilistic epistemology, highlighting the espousal by several seismologists (Bullen, Stoneley, Byerly), whose crustal models drew on mathematical idealisations. Next, I demonstrate that the renunciation of simplicity in the 1930s came about too quickly, and, above all, too heterodoxically to have been the result of new geological evidence. Rather, I argue, the paradigm shift among seismologists was a result of the significant rise in seismic exploration generated by the oil industry. Driven by market demands, American petroleum companies pioneered new technologies, organised research initiatives, and trained young geophysicists who, through the fusion of experimentalism and field experience, brought about fundamental progress in earthquake seismology. Remarkably, historians of science have almost entirely failed to recognise the interwar primacy of the simplicity paradigm as well as its subsequent renunciation. More importantly, they have failed to acknowledge the role the oil industry played in contributing to this renunciation and to the development of new paradigms in seismology.

    In this paper we consider the issue of paradigm evaluation by applying Bayes' theorem along the following nested hierarchy of progressively more complex structures: i) parameter estimation (within a model), ii) model selection and comparison (within a paradigm), iii) paradigm evaluation. In such a hierarchy the Bayesian evidence works both as the posterior's normalization at a given level and as the likelihood function at the next level up. Whilst raising no objections to the standard application of the procedure at the two lowest levels, we argue that it should receive a considerable modification when evaluating paradigms, when testability and fitting data are equally important. By considering toy models we illustrate how models and paradigms that are difficult to falsify are always favoured by the Bayes factor. We argue that the evidence for a paradigm should not only be high for a given dataset, but exceptional with respect to what it would have been, had the data been different. With this motivation we propose a measure which we term predictivity , as well as a prior to be incorporated into the Bayesian framework, penalising unpredictivity as much as not fitting data. We apply this measure to inflation seen as a whole, and to a scenario where a specific inflationary model is hypothetically deemed as the only one viable as a result of information alien to cosmology (e.g. Solar System gravity experiments, or particle physics input). We conclude that cosmic inflation is currently hard to falsify, but that this could change were external/additional information to cosmology to select one of its many models. We also compare this state of affairs to bimetric varying speed of light cosmology.

    2010-09-15

    Energy efficiency is the cheapest source of energy that has escaped the minds of the politicians in the developing countries. This paper argues for large scale utility led end use efficiency programs in a new paradigm, where 1 million efficient light bulbs is synonymous to a 50 MW power station that costs only 2% of the traditional fossil fuel power station and zero maintenance. Bulk procurement, setting up new standards and generation of certified emissions reduction is part of this strategy. It discusses implementation of a $20 million pilot in the Philippines supported by the Asian Development Bank.

    As a result of significant research over the past 20 years, black holes are now linked to some of the most spectacular and exciting phenomena in the Universe, ranging in size from those that have the same mass as stars to the super-massive objects that lie at the heart of most galaxies, including our own Milky Way. This book first introduces the properties of simple isolated holes, then adds in complications like rotation, accretion, radiation, and magnetic fields, finally arriving at a basic understanding of how these immense engines work. Black Hole Astrophysics • reviews our current knowledge of cosmic black holes and how they generate the most powerful observed pheonomena in the Universe; • highlights the latest, most up-to-date theories and discoveries in this very active area of astrophysical research; • demonstrates why we believe that black holes are responsible for important phenomena such as quasars, microquasars and gammaray bursts; • explains to the reader the nature of the violent and spe...

    A critical examination of RHIC paradigms is presented. Topics include: search for a critical point with a low energy scan; the lack of understanding of radiative processes in a medium in QCD compared in detail to examples from QED; the reason why some physicists started to measure particles at large p T in the 1960's; a review of the discovery of hard-scattering in p-p collisions in the 1970's via single-inclusive and two-particle correlations and application of these techniques at RHIC. Several paradigms in both soft and hard physics which are popular at RHIC are discussed and challenged.

    As a result of the rapid changes taking place in health care, nurse leaders are more challenged than ever to assume a new and different kind of leadership. Under the current paradigm, leaders are responsible for the performance of their people. Leaders do things TO the organization and the people in it. That paradigm of leader responsibility for other people's performance, given today's circumstances, guarantees organizational failure. A radical transformation in leadership thinking must take place. The leader's job is to get the people to be responsible for their own performance.

    2011-01-01

    Experimentally distinguishing different primordial universe paradigms that lead to the Big Bang model is an outstanding challenge in modern cosmology and astrophysics. We show that a generic type of signals that exist in primordial universe models can be used for such purpose. These signals are induced by tiny oscillations of massive fields and manifest as features in primordial density perturbations. They are capable of recording the time-dependence of the scale factor of the primordial universe, and therefore provide direct evidence for specific paradigm. These signals present special opportunities and challenges for experiments and data analyses.

  9. Effective field theory of dark matter from membrane inflationary paradigm

    Science.gov (United States)

    Choudhury, Sayantan; Dasgupta, Arnab

    2016-09-01

    In this article, we have studied the cosmological and particle physics constraints on dark matter relic abundance from effective field theory of inflation from tensor-to-scalar ratio (r), in case of Randall-Sundrum single membrane (RSII) paradigm. Using semi-analytical approach we establish a direct connection between the dark matter relic abundance (ΩDMh2) and primordial gravity waves (r), which establishes a precise connection between inflation and generation of dark matter within the framework of effective field theory in RSII membrane. Further assuming the UV completeness of the effective field theory perfectly holds good in the prescribed framework, we have explicitly shown that the membrane tension, σ ≤ O(10-9) Mp4 , bulk mass scale M5 ≤ O(0.04 - 0.05) Mp, and cosmological constant Λ˜5 ≥ - O(10-15) Mp5 , in RSII membrane plays the most significant role to establish the connection between dark matter and inflation, using which we have studied the features of various mediator mass scale suppressed effective field theory "relevant operators" induced from the localized s, t and u channel interactions in RSII membrane. Taking a completely model independent approach, we have studied an exhaustive list of tree-level Feynman diagrams for dark matter annihilation within the prescribed setup and to check the consistency of the obtained results, further we apply the constraints as obtained from recently observed Planck 2015 data and Planck + BICEP2 + Keck Array joint data sets. Using all of these derived results we have shown that to satisfy the bound on, ΩDMh2 = 0.1199 ± 0.0027, as from Planck 2015 data, it is possible to put further stringent constraint on r within, 0.01 ≤ r ≤ 0.12, for thermally averaged annihilation cross-section of dark matter, 〈 σv 〉 ≈ O(10-28 - 10-27) cm3 / s, which are very useful to constrain various membrane inflationary models.

    2002-01-01

    The first goal of this study was to systematically document asymmetries in vertical saccade generation. We found that visually guided upward saccades have not only shorter latencies, but higher peak velocities, shorter durations and smaller errors. The second goal was to identify possible mechanisms underlying the asymmetry in vertical saccade latencies. Based on a recent model of saccade generation, three stages of saccade generation were investigated using specific behavioral paradigms: attention shift to a visual target (CUED paradigm), initiation of saccade generation (GAP paradigm) and release of the motor command to execute the saccade (DELAY paradigm). Our results suggest that initiation of a saccade (or "ocular disengagement") and its motor release contribute little to the asymmetry in vertical saccade latency. However, analysis of saccades made in the CUED paradigm indicated that it took less time to shift attention to a target in the upper visual field than to a target in the lower visual field. These data suggest that higher attentional sensitivity to targets in the upper visual field may contribute to shorter latencies of upward saccades.

    Linguistics like any science has undergone a series of paradigm changes, one of the most important being the change from the view of language as a sign system to that of language-in-use. In the face of the progress made in the natural and social sciences in recent years, from biology to economics, the question has to be posed where linguistics and…

    Social neuroscience has called for new experimental paradigms aimed toward real-time interactions. A distinctive feature of interactions is mutual information exchange: One member of a pair changes in response to the other while simultaneously producing actions that alter the other. Combining mathematical and neurophysiological methods, we introduce a paradigm called the human dynamic clamp (HDC), to directly manipulate the interaction or coupling between a human and a surrogate constructed to behave like a human. Inspired by the dynamic clamp used so productively in cellular neuroscience, the HDC allows a person to interact in real time with a virtual partner itself driven by well-established models of coordination dynamics. People coordinate hand movements with the visually observed movements of a virtual hand, the parameters of which depend on input from the subject's own movements. We demonstrate that HDC can be extended to cover a broad repertoire of human behavior, including rhythmic and discrete movements, adaptation to changes of pacing, and behavioral skill learning as specified by a virtual "teacher." We propose HDC as a general paradigm, best implemented when empirically verified theoretical or mathematical models have been developed in a particular scientific field. The HDC paradigm is powerful because it provides an opportunity to explore parameter ranges and perturbations that are not easily accessible in ordinary human interactions. The HDC not only enables to test the veracity of theoretical models, it also illuminates features that are not always apparent in real-time human social interactions and the brain correlates thereof.

    2017-02-01

    A paradigm is an accepted world view. If we do not continually question our paradigm then wider trends and movements will overtake the discipline leaving it ill adapted to future challenges. This Special Issue is an opportunity to keep systems thinking at the forefront of ergonomics theory and practice. Systems thinking prompts us to ask whether ergonomics, as a discipline, has been too timid? Too preoccupied with the resolution of immediate problems with industrial-age methods when, approaching fast, are developments which could render these operating assumptions an irrelevance. Practical case studies are presented to show how abstract systems problems can be tackled head-on to deliver highly innovative and cost-effective insights. The strategic direction of the discipline foregrounds high-quality systems problems. These are something the discipline is well able to respond to provided that the appropriate operating paradigms are selected. Practitioner Summary: High-quality systems problems are the future of the discipline. How do we convert obtuse sounding systems concepts into practical interventions? In this paper, the essence of systems thinking is distilled and practical case studies used to demonstrate the benefits of this new paradigm.

    2013-01-01

    In order to propose a framework and programming paradigms for post peta-scale computing, on the road to exa-scale computing and beyond, we introduced new languages, associated with a hierarchical multi-level programming paradigm, allowing scientific end-users and developers to program highly hierarchical architectures designed for extreme computing. In this paper, we explain the interest of such hierarchical multi-level programming paradigm for extreme computing and its well adaptation to several large computational science applications, such as for linear algebra solvers used for reactor core physic. We describe the YML language and framework allowing describing graphs of parallel components, which may be developed using PGAS-like language such as XMP, scheduled and computed on supercomputers. Then, we propose experimentations on supercomputers (such as the 'K' and 'Hooper' ones) of the hybrid method MERAM (Multiple Explicitly Restarted Arnoldi Method) as a case study for iterative methods manipulating sparse matrices, and the block Gauss-Jordan method as a case study for direct method manipulating dense matrices. We conclude proposing evolutions for this programming paradigm. (authors)

  1. A Longitudinal analysis of the Porterian paradigm utilization in Brazil

    Directory of Open Access Journals (Sweden)

    Simone Sehnem

    2010-01-01

    Full Text Available The purpose of this article is to investigate to what extent Michael Porter's ideas keep attracting the interest of Brazilian researchers vis-à-vis other possibilities. In this research, we conceptualize Porter's paradigm by the the following elements: strategic groups, generic strategies, model of the five forces and value chain. Weanalyzed conferece communications to EnANPAD¿s, from 1998 to 2008, and to 3Es, from 2003to 2007. The results indicate a decline in the use of the porterian paradigm as the main axis of research in strategy. The generic strategies and the model of five forces are the elements of Porter's paradigm most employed, while the concepts of strategic groups and value chain are the ones that received less attention by researchers. The analysis of methodology and purpose of comunications indicates that the "porterian life" in Brazil was characterized by the acritical use of its concepts in order to describe the reality of the strategy in Brazil. There are no evidences of consistent and systematic attempts to test or adapt the porterian paradigm for the Brazilian context. And results indicate no evidences that this trend will be reversed.

    Full Text Available The purpose of the work is finding the reasonability of using bio-evolutionary paradigm for researching ratio morphic cognitive activity. Methodology. Methodological grounds consist of the original principles and conceptual apparatus of evolutionary epistemology. Scientific novelty. The article identifies opportunities for using of biological and evolutionary paradigm to study the peculiarities of ratiomorphic cognitive backgrounds and their influence on the formation and development of human knowledge. Conclusions. The article concludes that together with the idea of hyper cycles (feedback loop with mutual transmission of information in cognitive process the concept of ratiomorphic cognitive backgrounds, as well as attempts to examine cognitive processes based on the scientific criteria (empirical verification, explanatory power and ability to predict should be certainly considered as a positive contribution to the development of evolutionary epistemology into modern epistemological research. However, it is also indicated the fact of narrowing the heuristic possibilities of this epistemological direction because of excessive metaphor of bio-evolutionary paradigm. Further development of evolutionary epistemological research is considered in shifting the emphasis from biological and evolutionary towards cultural and evolutionary paradigm.

    Reynolds, Heather L; Smith, Alex A; Farmer, James R

    2014-10-01

    Conducting science for practical ends implicates scientists, whether they wish it or not, as agents in social-ecological systems, raising ethical, economic, environmental, and political issues. Considering these issues helps scientists to increase the relevance and sustainability of research outcomes. As we rise to the worthy call to connect basic research with food production, scientists have the opportunity to evaluate alternative food production paradigms and consider how our research funds and efforts are best employed. In this contribution, we review some of the problems produced by science conducted in service of industrial agriculture and its associated economic growth paradigm. We discuss whether the new concept of "ecological intensification" can rescue the industrial agriculture/growth paradigm and present an emerging alternative paradigm of decentralized, localized, biodiversity-promoting agriculture for a steady-state economy. This "custom fit" agriculture engages constructively with complex and highly localized ecosystems, and we draw from examples of published work to demonstrate how ecologists can contribute by using approaches that acknowledge local agricultural practices and draw on community participation. © 2014 Botanical Society of America, Inc.

    1993-01-01

    The Software Engineering Laboratory uses a paradigm for improving the software process and product, called the quality improvement paradigm. This paradigm has evolved over the past 18 years, along with our software development processes and product. Since 1976, when we first began the SEL, we have learned a great deal about improving the software process and product, making a great many mistakes along the way. Quality improvement paradigm, as it is currently defined, can be broken up into six steps: characterize the current project and its environment with respect to the appropriate models and metrics; set the quantifiable goals for successful project performance and improvement; choose the appropriate process model and supporting methods and tools for this project; execute the processes, construct the products, and collect, validate, and analyze the data to provide real-time feedback for corrective action; analyze the data to evaluate the current practices, determine problems, record findings, and make recommendations for future project improvements; and package the experience gained in the form of updated and refined models and other forms of structured knowledge gained from this and prior projects and save it in an experience base to be reused on future projects.

  14. A nonmusical paradigm for identifying absolute pitch possessors

    Science.gov (United States)

    Ross, David A.; Olson, Ingrid R.; Marks, Lawrence E.; Gore, John C.

    2004-09-01

    The ability to identify and reproduce sounds of specific frequencies is remarkable and uncommon. The etiology and defining characteristics of this skill, absolute pitch (AP), have been very controversial. One theory suggests that AP requires a specific type of early musical training and that the ability to encode and remember tones depends on these learned musical associations. An alternate theory argues that AP may be strongly dependent on hereditary factors and relatively independent of musical experience. To date, it has been difficult to test these hypotheses because all previous paradigms for identifying AP have required subjects to employ knowledge of musical nomenclature. As such, these tests are insensitive to the possibility of discovering AP in either nonmusicians or musicians of non-Western training. Based on previous literature in pitch memory, a paradigm is presented that is intended to distinguish between AP possessors and nonpossessors independent of the subjects' musical experience. The efficacy of this method is then tested with 20 classically defined AP possessors and 22 nonpossessors. Data from these groups strongly support the validity of the paradigm. The use of a nonmusical paradigm to identify AP may facilitate research into many aspects of this phenomenon.

  17. Cloud Manufacturing Service Paradigm for Group Manufacturing Companies

    Directory of Open Access Journals (Sweden)

    Jingtao Zhou

    2014-07-01

    Full Text Available The continuous refinement of specialization requires that the group manufacturing company must be constantly focused on how to concentrate its core resources in special sphere to form its core competitive advantage. However, the resources in enterprise group are usually distributed in different subsidiary companies, which means they cannot be fully used, constraining the competition and development of the enterprise. Conducted as a response to a need for cloud manufacturing studies, systematic and detailed studies on cloud manufacturing schema for group companies are carried out in this paper. A new hybrid private clouds paradigm is proposed to meet the requirements of aggregation and centralized use of heterogeneous resources and business units distributed in different subsidiary companies. After the introduction of the cloud manufacturing paradigm for enterprise group and its architecture, this paper presents a derivation from the abstraction of paradigm and framework to the application of a practical evaluative working mechanism. In short, the paradigm establishes an effective working mechanism to translate collaborative business process composed by the activities into cloud manufacturing process composed by services so as to create a foundation resulting in mature traditional project monitoring and scheduling technologies being able to be used in cloud manufacturing project management.

    2015-01-01

    Full Text Available The application of systems theory and the study of complexity to medicine and human health allows for a more comprehensive understanding and a more holistic view of what it means to be human. Such application overcomes the limitations of the traditional, fragmented understanding of phenomena and problems based on the mechanistic or Newtonian worldview. It recognizes that phenomena are interrelated, and that individual parts cannot be understood by only focusing on the analysis of their individual qualities. Rather, the individual parts can only be understood in relation to the whole and by being analyzed in the context of their interaction with the whole. The door is opened to previously unimagined models of thinking.In the 20th Century there have been shifts in the paradigms that have governed medicine and human health in the modern western world. There has been a shift from the focus on specific biological analysis and pathological diagnostics to complex human interactions with the environment and with sociopolitical and economic processes. There are complex models of systems in immunology, in neuroscience, and in genetics, as well as complex ways of understanding interactions as in epidemic modeling, in social media technologies, socioeconomic factors, and artificial intelligence.In this paper we describe three paradigms of the health-disease process that in some degree correspond to the historical development of modern medicine and healthcare over the previous century. The oldest paradigm focused on specific disease mechanisms and treatment. This gave way to paradigms that historically were broader and more inclusive, such as “international health”. The international health paradigm focused primarily on the control of epidemics across national borders and considered government as the only health actor. However, this perspective has come to be seen as excessively reductionist and excluded many critical components essential to a robust

    Repository as RDF-triples. An off-the-shelf Ontology Development Environment and a custom Metadata Conversion Tool comprise a human-machine/machine-machine hybrid tool that partially automates the creation of metadata as RDF-triples by interfacing with existing metadata repositories and providing a user interface that solicits input from a human user, when needed. RDF-triples are pushed to the Ontology Development Environment, where a reasoning engine executes a series of inference rules whose antecedent conditions can be satisfied by the initial set of RDF-triples, thereby generating the additional detailed metadata that is missing in existing repositories. A SPARQL Endpoint, a web-based query service and a Graphical User Interface allow prospective data consumers - even those with no familiarity with NASA data products - to search the metadata repository to find and order data products that meet their exact specifications. A web-based API will provide an interface for machine-to-machine transactions.

    Science.gov (United States)

    1989-01-01

    When Enerpro, Inc. president, Frank J. Bourbeau, attempted to file a patent on a system for synchronizing a wind generator to the electric utility grid, he discovered Marshall Space Flight Center's Frank Nola's power factor controller. Bourbeau advanced the technology and received a NASA license and a patent for his Auto Synchronous Controller (ASC). The ASC reduces generator "inrush current," which occurs when large generators are abruptly brought on line. It controls voltage so the generator is smoothly connected to the utility grid when it reaches its synchronous speed, protecting the components from inrush current damage. Generator efficiency is also increased in light winds by applying lower than rated voltage. Wind energy is utilized to drive turbines to generate electricity for utility companies.

  3. The Risk-Benefit Paradigm vs the Causal Exposure Paradigm: LDL as a primary cause of vascular disease.

    2014-01-01

    All current guidelines use the 10-year risk of a cardiovascular event to select subjects for statin primary preventive therapy. Benefit from therapy is stated to be determined by risk with the result that statin primary preventive therapy is initiated only when the risk of a cardiovascular event over the next decade exceeds a specified level. Thus all current guidelines are based primarily on the Risk-Benefit paradigm of primary prevention. The recent American Heart Association/American College of Cardiology guidelines differ from others in basing selection for statin therapy virtually exclusively on risk except for those few subjects with markedly elevated levels of low-density lipoprotein cholesterol (LDL-C). The Causal Exposure paradigm differs from the Risk-Benefit paradigm in that the objective of therapy is to prevent the anatomic disease within arterial walls that produces cardiovascular risk. Moreover, the anatomic disease and, therefore, the cardiovascular risk, is a function of the injurious action of the causal factors of vascular disease, such as blood pressure and LDL, on the arterial wall over long periods. In this article, we explain the strengths and weaknesses of both paradigms to provide a more secure framework to compare the strengths and weaknesses in the different cholesterol guidelines with particular emphasis on the evidence that the cardiovascular risk and the benefit from statin therapy is related to the level of LDL.

    2011-01-01

    In most psychological experiments, a randomized presentation of successive displays is crucial for the validity of the results. For some paradigms, this is not a trivial issue because trials are interdependent, e.g., priming paradigms. We present a software that automatically generates optimized trial sequences for (negative-) priming experiments. Our implementation is based on an optimization heuristic known as genetic algorithms that allows for an intuitive interpretation due to its similarity to natural evolution. The program features a graphical user interface that allows the user to generate trial sequences and to interactively improve them. The software is based on freely available software and is released under the GNU General Public License.

    Luo, Hongyuan; Wang, Deyun; Yue, Chenqiang; Liu, Yanling; Guo, Haixiang

    2018-03-01

    In this paper, a hybrid decomposition-ensemble learning paradigm combining error correction is proposed for improving the forecast accuracy of daily PM10 concentration. The proposed learning paradigm is consisted of the following two sub-models: (1) PM10 concentration forecasting model; (2) error correction model. In the proposed model, fast ensemble empirical mode decomposition (FEEMD) and variational mode decomposition (VMD) are applied to disassemble original PM10 concentration series and error sequence, respectively. The extreme learning machine (ELM) model optimized by cuckoo search (CS) algorithm is utilized to forecast the components generated by FEEMD and VMD. In order to prove the effectiveness and accuracy of the proposed model, two real-world PM10 concentration series respectively collected from Beijing and Harbin located in China are adopted to conduct the empirical study. The results show that the proposed model performs remarkably better than all other considered models without error correction, which indicates the superior performance of the proposed model.

  14. The emerging health paradigm in the 21st century: the formative first 1000 days of life

    2016-01-01

    Full Text Available During the 20th Century Western society's thinking regarding health and wellbeing underwent profound and rapid changes. Towards the end of the century, a health paradigm based on social health determinants emerged, providing a strong foundation for influencing priorities in global health. In this paper we will present evidence that supports a new paradigm. It avers that human health and development is founded on infants’ brain architecture and their capacity to transform the brains and lives of adults. Neuroscience now shows how the brain architecture of the person becomes established during the intrauterine period and the first two to three years of life. This brain architecture determines the capacity of the organism to self-regulate its biological, emotional, cognitive, and interactional processes with the environment. The more robust this brain architecture, the more potential and capability that individual has to enjoy physical, emotional, and mental health as well as his/her capacity to contribute to the health and wellbeing of others. We hold that the transformative value of infants to society is biblical. This new understanding can generate a shift towards a focus on early infancy as the best strategy to foster development of healthy and sustainable societies.

  15. Error Recovery in the Time-Triggered Paradigm with FTT-CAN.

    Data networks are naturally prone to interferences that can corrupt messages, leading to performance degradation or even to critical failure of the corresponding distributed system. To improve resilience of critical systems, time-triggered networks are frequently used, based on communication schedules defined at design-time. These networks offer prompt error detection, but slow error recovery that can only be compensated with bandwidth overprovisioning. On the contrary, the Flexible Time-Triggered (FTT) paradigm uses online traffic scheduling, which enables a compromise between error detection and recovery that can achieve timely recovery with a fraction of the needed bandwidth. This article presents a new method to recover transmission errors in a time-triggered Controller Area Network (CAN) network, based on the Flexible Time-Triggered paradigm, namely FTT-CAN. The method is based on using a server (traffic shaper) to regulate the retransmission of corrupted or omitted messages. We show how to design the server to simultaneously: (1) meet a predefined reliability goal, when considering worst case error recovery scenarios bounded probabilistically by a Poisson process that models the fault arrival rate; and, (2) limit the direct and indirect interference in the message set, preserving overall system schedulability. Extensive simulations with multiple scenarios, based on practical and randomly generated systems, show a reduction of two orders of magnitude in the average bandwidth taken by the proposed error recovery mechanism, when compared with traditional approaches available in the literature based on adding extra pre-defined transmission slots.

  16. Colors in mind: a novel paradigm to investigate pure color imagery.

    Wantz, Andrea L; Borst, Grégoire; Mast, Fred W; Lobmaier, Janek S

    2015-07-01

    Mental color imagery abilities are commonly measured using paradigms that involve naming, judging, or comparing the colors of visual mental images of well-known objects (e.g., "Is a sunflower darker yellow than a lemon"?). Although this approach is widely used in patient studies, differences in the ability to perform such color comparisons might simply reflect participants' general knowledge of object colors rather than their ability to generate accurate visual mental images of the colors of the objects. The aim of the present study was to design a new color imagery paradigm. Participants were asked to visualize a color for 3 s and then to determine a visually presented color by pressing 1 of 6 keys. We reasoned that participants would react faster when the imagined and perceived colors were congruent than when they were incongruent. In Experiment 1, participants were slower in incongruent than congruent trials but only when they were instructed to visualize the colors. The results in Experiment 2 demonstrate that the congruency effect reported in Experiment 1 cannot be attributed to verbalization of the color that had to be visualized. Finally, in Experiment 3, the congruency effect evoked by mental imagery correlated with performance in a perceptual version of the task. We discuss these findings with respect to the mechanisms that underlie mental imagery and patients suffering from color imagery deficits. (c) 2015 APA, all rights reserved.

    Recent reports suggested better outcomes associated with the drip-and-ship paradigm for acute ischemic stroke (AIS) treated with thrombolysis. We hypothesized that a higher rate of stroke mimics (SM) among AIS treated in nonspecialized stroke centers that are transferred to comprehensive centers is responsible for such outcomes. Consecutive patients treated with thrombolysis according to the admission criteria were reviewed in a single comprehensive stroke center over 1 academic year (July 1, 2011 to June 30, 2012). Information on the basic demographic, hospital complications, psychiatric diagnoses, and discharge disposition was collected. We identified those patients who were treated at a facility and then transferred to the tertiary center (ie, drip-and-ship paradigm). In addition to comparative and adjusted analysis to identify predictors for SM, a stratified analysis by the drip-and-ship status was performed. One hundred twenty patients were treated with thrombolysis for AIS included in this analysis; 20 (16.7%) were discharged with the final diagnosis of SM; 14 of those had conversion syndrome and 6 patients had other syndromes (seizures, migraine, and hypoglycemia). Patients with SM were younger (55.6 ± 15.0 versus 69.4 ± 14.9, P = .0003) and more likely to harbor psychiatric diagnoses (45% versus 9%; P ≤ .0001). Eighteen of 20 SM patients (90%) had the drip-and-ship treatment paradigm compared with 65% of those with AIS (P = .02). None of the SM had hemorrhagic complications, and all were discharged to home. Predictors of SM on adjusted analysis included the drip-and-ship paradigm (odds ratio [OR] 12.8, 95% confidence interval [CI] 1.78, 92.1) and history of any psychiatric illness (OR 12.08; 95% CI 3.14, 46.4). Eighteen of 83 drip-and-ship patients (21.7%) were diagnosed with SM compared with 2 of 37 patients (5.4%) presented directly to the hub hospital (P = .02). The drip-and-ship paradigm and any psychiatric history predict the diagnosis of

    In the 1970s, seismic stratigraphy represented a new paradigm in geological thought. The development of new techniques for analyzing seismic-reflection data constituted a "crisis," as conceptualized by T.S. Kuhn, and stimulated a revolution in stratigraphy. We analyze here a specific subset of the new ideas, that pertaining to the concept of global-eustasy and the global cycle chart published by Vail et al. [Vail, P.R., Mitchum, R.M., Jr., Todd, R.G., Widmier, J.M., Thompson, S., III, Sangree, J.B., Bubb, J.N., Hatlelid, W.G., 1977. Seismic stratigraphy and global changes of sea-level. In: Payton, C.E. (Ed.), Seismic Stratigraphy—Applications to Hydrocarbon Exploration, Am. Assoc. Pet. Geol. Mem. 26, pp. 49-212.] The global-eustasy model posed two challenges to the "normal science" of stratigraphy then underway: (1) that sequence stratigraphy, as exemplified by the global cycle chart, constitutes a superior standard of geologic time to that assembled from conventional chronostratigraphic evidence, and (2) that stratigraphic processes are dominated by the effects of eustasy, to the exclusion of other allogenic mechanisms, including tectonism. While many stratigraphers now doubt the universal validity of the model of global-eustasy, what we term the global-eustasy paradigm, a group of sequence researchers led by Vail still adheres to it, and the two conceptual approaches have evolved into two conflicting paradigms. Those who assert that there are multiple processes generating stratigraphic sequences (possibly including eustatic processes) are adherents of what we term the complexity paradigm. Followers of this paradigm argue that tests of the global cycle chart amount to little more than circular reasoning. A new body of work documenting the European sequence record was published in 1998 by de Graciansky et al. These workers largely follow the global-eustasy paradigm. Citation and textual analysis of this work indicates that they have not responded to any of the

    Within the hypnosis field, there is a disparity between clinical and research worldviews. Clinical practitioners work with patients who are dealing with serious, often unique, real-world problems-lived experience. Researchers adhere to objective measurements, standardization, data, and statistics. Although there is overlap, an ongoing divergence can be counterproductive to the hypnosis field and to the larger professional and social contexts. The purpose of this article is: (1) to examine some of the major assumptions, the history, and the philosophy that undergird the definition of science, which was constructed in the mid-17th century; (2) to discover how science is a product of prevailing social forces and is undergoing a paradigm shift; and (3) to understand the more encompassing, holistic paradigm with implications for the hypnosis field.

    Full Text Available Two prevailing paradigms in contemporary international migration research – migration as unpredictable explosion and migration as mainly predictable long cycles movement – are put into question. Both paradigms are not valid in explaining latest development in international migration field. They are too robust for reality which is satiated with novel developments in the field of volume, directions, labour markets and structure of migration flows, both voluntary and involuntary. Individual independent migrant as decision maker is coming to the fore. Therefore the reassessment of theoretical and conceptual apparatus of migration is imminent. As to the methods, mathematically supported sociological models of contemporary migration could be needed. On the basis of “new intuition”, the principles of simplicity, parsimony, and universality could lead to a theoretical innovation.

    Technoeconomic paradigms based economic growth theories suggest that waves of technological innovations drove the economic growth of advanced economies. Widespread economic degradation and pollution is an unintended consequence of such growth. Tackling environmental and social issues at firm levels would help us to overcome such issues at macro-levels. Consequently, the Triple Bottom Line (TBL) reporting approach promotes firm level economic, environmental and social performances. Incorporating Zink's (2014) 3-pillar presentation model, this paper indicates that economic, social and environmental performances tend to be reported at firm level. All three pillars are not covered evenly at the activity levels. Thus, a loophole is identified whereby excellent environmental performance at activity levels could potentially leave poor social performance undisclosed. A refinement of the TBL paradigm, whereby all three pillars are covered at the activity level, is suggested, to enhance sustainability reporting. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Objectives: Functional magnetic resonance imaging (fMRI is a reliable and non-invasive method with which to localize language function in pre-surgical planning. In clinical practice, visual stimulus presentation is often difficult or impossible, due to the patient’s restricted language or attention abilities. Therefore, our aim was to investigate modality-specific differences in visual and auditory stimulus presentation.Methods: Ten healthy subjects participated in an fMRI study comprising two experiments with visual and auditory stimulus presentation. In both experiments, two language paradigms (one for language comprehension and one for language production used in clinical practice were investigated. In addition to standard data analysis by the means of the general linear model (GLM, independent component analysis (ICA was performed to achieve more detailed information on language processing networks.Results: GLM analysis revealed modality-specific brain activation for both language paradigms for the contrast visual > auditory in the area of the intraparietal sulcus and the hippocampus, two areas related to attention and working memory. Using group ICA, a language network was detected for both paradigms independent of stimulus presentation modality. The investigation of language lateralization revealed no significant variations. Visually presented stimuli further activated an attention-shift network, which could not be identified for the auditory presented language.Conclusion: The results of this study indicate that the visually presented language stimuli additionally activate an attention-shift network. These findings will provide important information for pre-surgical planning in order to preserve reading abilities after brain surgery, significantly improving surgical outcomes. Our findings suggest that the presentation modality for language paradigms should be adapted on behalf of individual indication.

  13. Agua Para Todos: A New Regionalist Hydraulic Paradigm in Spain

    Directory of Open Access Journals (Sweden)

    Elena Lopez-Gunn

    2009-10-01

    Full Text Available This paper reviews the hydraulic paradigm in Spain and its evolution over the last 100 years to the current decentralisation process of "agua para todos", i.e. where different regional governments vie for control over 'scarce' water resources and defining the concept of hydro-solidarity between regions. Recent events seem to point to a new hydraulic bureaucracy at the sub-national level due to the political devolution currently taking place in Spain, where water has an increased political value in electoral terms. Water has strategic importance in single-issue politics and territorial identity, as compared to traditional left/right ideological politics for both national and regional parties in the Spanish multilevel electoral system. This refers to an important aspect of water politics – openly discussed in Spain but rarely analysed – namely the 'political returns' on water (or 'political rent-seeking'. This also points to spatial dimensions of the definition of state, identity, and access to resources in a semiarid country. This historical process of decentralisation of water is highlighted with particular reference to key events in recent Spanish history, including the Hydraulic Plan of the 1930s, its reappearance in the 1993 National Hydrological Plan, a revised version in the year 2001, and a final change in paradigm in 2005 at the national level. This suggests that the hydraulic paradigm is re-enacted at the regional government level. It is argued that a multi-scalar analysis of Spanish water decentralisation is essential in order to understand change and stasis in public policy paradigms related to water.

    2013-01-01

    Antarctic marine ecosystems have undergone significant changes as a result of human activities in the past and are now responding in varied and often complicated ways to climate change impacts. Recent years have seen the emergence of large-scale mechanistic explanations–or “paradigms of change”–that attempt to synthesize our understanding of past and current changes. In many cases, these paradigms are based on observations that are spatially and temporally patchy. The West Antarctic Peninsula (WAP), one of Earth’s most rapidly changing regions, has been an area of particular research focus. A recently proposed mechanistic explanation for observed changes in the WAP region relates changes in penguin populations to variability in krill biomass and regional warming. While this scheme is attractive for its simplicity and chronology, it may not account for complex spatio-temporal processes that drive ecosystem dynamics in the region. It might also be difficult to apply to other Antarctic regions that are experiencing some, though not all, of the changes documented for the WAP. We use qualitative network models of differing levels of complexity to test paradigms of change for the WAP ecosystem. Importantly, our approach captures the emergent effects of feedback processes in complex ecological networks and provides a means to identify and incorporate uncertain linkages between network elements. Our findings highlight key areas of uncertainty in the drivers of documented trends, and suggest that a greater level of model complexity is needed in devising explanations for ecosystem change in the Southern Ocean. We suggest that our network approach to evaluating a recent and widely cited paradigm of change for the Antarctic region could be broadly applied in hypothesis testing for other regions and research fields.
