  4. Processing of verb tense

    2002-01-01

    Full Text Available Processing of Serbian inflected verbs was investigated in two lexical decision experiments. In the first experiment subjects were presented with five forms of future tense, while in the second experiment the same verbs were presented in three forms of present and future tense. The outcome of the first experiment indicates that processing of inflected verb is determined by the amount of information derived from the average probability per congruent personal pronoun of a particular verb form. This implies that the cognitive system is not sensitive to verb person per se, nor to the gender of congruent personal pronoun. Results of the second experiment show that for verb forms of different tenses, presented in the same experiment, the amount of information has to be additionally modulated by tense probability. Such an outcome speaks in favor of cognitive relevance of verb tense.

    Blackburn, Patrick Rowan; Jørgensen, Klaus Frovin

    2012-01-01

    In this paper we explore the logic of now, yesterday, today and tomorrow by combining the semantic approach to indexicality pioneered by Hans Kamp [9] and refined by David Kaplan [10] with hybrid tense logic. We first introduce a special now nominal (our @now corresponds to Kamp’s original now...... operator N) and prove completeness results for both logical and contextual validity. We then add propositional constants to handle yesterday, today and tomorrow; our system correctly treats sentences like “Niels will die yesterday” as contextually unsatisfiable. Building on our completeness results for now......, we prove completeness for the richer language, again for both logical and contextual validity....

  10. Children's Typically-Perceived-Situations of Force and No Force in the Context of Australia and Korea

    2010-08-01

    Typically-Perceived-Situation (TPS) refers to the situation rising spontaneously in an individual's mind when she/he first thinks of a phenomenon or concept. The purpose of this study is to go well beyond the many studies that describe conceptions of force and explore children's TPS of "force is acting on a thing" and "force is not acting on a thing", and to do this in the differing contexts of Australia and Korea. Data were collected by drawings and written explanations from 145 Grade 6 Australian children and 150 Grade 6 Korean children. These data showed some significant differences between the Australian children's and Korean children's TPSs. For example, considering the whole context of children's TPS, the contexts of "someone pushes or pulls something" and "someone/something is floating in the air or not moving because there is no gravity" were the most frequent ones, as a "force" and as a "no force" situation respectively, in the case of Australian children, while "a sort of energy is provided into someone/something and they can be active/working" and "a sort of energy is not provided into someone/something and they cannot be active/working", were most frequent in the case of Korean children. These differences are very likely the consequence of different everyday meanings for the word "force" in the two cultures. In addition, it appears that these children's TPS affect their judgement of "force" and "no force".

    Full Text Available Yuka (1997 has identified three broad tenses in Lamnso’2. A closer look at these tenses and their specification of time reference willreveal a more complex tense structure of multiple past and future timeallusions that distinguish different degrees of remoteness to the pastand future tense categories. This paper seeks to determine the variousdegrees of remoteness to a given tense category exhibited in Lamnso’. This paper investigates the relative relationship(s between a tense marker that denotes the time of an action and the time reference preceding or following that action within the clause. It also examines aspect, interpreted as the way of conceiving the flow of an event (Comrie, 1976. This study identifies seven tense forms for Lamnso’ (P3, P2, P1, P0, F1, F2 and F3., which specify time distinctions from the remote past (P3 to the remote future (F3 and three aspect forms. These ten tense and aspect forms combine with distinctive tones and time adverbials to derive a time reference structure whose cut-off points are sometimes fluid and non-rigid.

    Students of English Language Education Program in Faculty of Cultural Studies Universitas Brawijaya ideally master Grammar before taking the degree of Sarjana Pendidikan. However, the fact shows that they are still weak in Grammar especially tenses. Therefore, the researchers initiate to develop a video as a media to teach tenses. Objectively, by using video, students get better understanding on tenses so that they can communicate using English accurately and contextually. To develop the video, the researchers used ADDIE model (Analysis, Design, Development, Implementation, Evaluation. First, the researchers analyzed the students’ learning need to determine the product that would be developed, in this case was a movie about English tenses. Then, the researchers developed a video as the product. The product then was validated by media expert who validated attractiveness, typography, audio, image, and usefulness and content expert and validated by a content expert who validated the language aspects and tenses of English used by the actors in the video dealing with the grammar content, pronunciation, and fluency performed by the actors. The result of validation shows that the video developed was considered good. Theoretically, it is appropriate to be used English Grammar classes. However, the media expert suggests that it still needs some improvement for the next development especially dealing with the synchronization between lips movement and sound on the scenes while the content expert suggests that the Grammar content of the video should focus on one tense only to provide more detailed concept of the tense.

  13. Levitation force of melt-textured YBCO superconductors under non-quasi-static situation

    The superconducting levitation force of a simple superconductor-magnet system under non-quasi-static situation is investigated experimentally. Two yttrium barium copper oxide (YBCO) samples with different performances are chosen from two small batches of samples prepared by the top-seeded melt-textured growth process. The residual carbon content of the precursor powders of the two batches is different due to different heat treatment processes. During the experimental process for measuring the levitation force, the value of the relative speed between the YBCO sample and the permanent magnet is higher than that in conventional studies. The variation characteristics of the superconducting levitation force are analyzed and a crossing phenomenon in the force-displacement hysteresis curves is observed. The results indicate that the superconducting levitation force is different due to the different residual carbon contents. As residual carbon contents reduce, the crossing phenomenon is more obvious accordingly.

    The prolonged sociopolitical phenomenon of Colombian violence generated a high number of victims, many of whom suffered a continual process of internal displacement and stigma-discrimination complex. To postulate possible mechanisms by which victims of Colombia's internal armed conflict in a situation of forced displacement were stigmatized and discriminated. Stigma affects mental health, not only because it represents a major stressor for discriminated individuals and groups, but also because it accounts for inequalities and inequities in health. Initially, as the victims of the internal armed conflict in situation of forced displacement were not considered as such, but as responsible for the situation. Thus, they had to cope with the social and economic inequalities, explained partially by low categorization or status that they received, possibly due to poor construction of social capital in the country. Also, victims of the internal armed conflict suffer from intersectional stigma and discrimination due to other characteristics such as gender, sexual orientation, ethnic-racial origin, or meeting criteria for a mental disorder. An active process of inclusive social development is required for the displaced victims of the armed conflict,in order to reduce multiple stigma and ensure their mental health.

    Full Text Available The aim of this article is to analyse the sequence of tenses in Spanish, a phenomenon typical of the Romance languages. Our purpose is to systematize and formulate the rules of use by means of examples with graphical representations. We focus on such cases of use of the sequence of tenses where it is possible to apply a “double-access interpretation”, i. e. which allows the possibility of choosing between reference points: with the actual time (the moment of speech or with the main clause. This double interpretation is to be found in all three types of time relationships: simultaneousness, priority and posteriority. Some pairs differ semantically; others are used according to the preferences of the speaker with no change of meaning. Most examples are subordinate noun clauses, nonetheless we included examples of other types of clauses as well (e.g. relative, reason clauses. We also analyze the problem of the sequence of tenses where the main verb is in the conditional tense.

    Full Text Available The production of verb tenses leads to better language development of children with cochlear implants. The aim of this study was to assess the acquisition of verb tenses in children with cochlear implants. The sample included 60 children, aged from 9 to 15, with average intellectual abilities. The study group consisted of 30 patients with cochlear implants, with no additional disabilities. The control group consisted of 30 subjects with typical speech - language development and preserved hearing. The acquisition of basic tenses was assessed by 'Corpus for the Assessment of the Use of Tenses' (Dimić, 2003. Significant statistical differences were found in the use of the present tense in children with cochlear implants and hearing children (t=-4.385; p<0.001 as well as in the use of the past tense (t=-4.650; p<0.001, and the future tense (t=-4.269; p<0.001. There was also a significant difference in the use of irregular verb 'go' (t=-3.958; p<0.001, as well as in the combination of the present and the past tense (t=-5.806; p<0.001. The present tense was used correctly by most children with cochlear implants (70%, followed by the past tense (53%, and finally the future tense (23%. Children with cochlear implants, even after several years of re/habilitation, do not reach the grammatical development of children with normal hearing.

    We examine the inflectional productions of seven Catalan, seven Galician, and seven Spanish speaking agrammatic subjects in an elicitation and a sentence repetition task and consider them in the light of the Tree Pruning Hypothesis (TPH). The results show relatively spared subject person/number agreement with the verb and impaired tense marking for all subjects in all the languages. Recent reformulations of syntactic theory [Chomsky (1999) MIT Occasional Papers in Linguistics (vol. 18). MA: The MIT Press; (2000). Step by Step: Essays on Minimalist Syntax in Honor of Howard Lasnik (pp. 89-155). Cambridge, MA: The MIT Press] regarding the locus of agreement force a reconsideration of the TPH for it to make the desired predictions; we adopt Cinque's [(1999) Adverbs and Functional Heads: A Cross-linguistic Perspective. Oxford: Oxford University Press] array of functional mood/tense/aspect projections and we show that subject agreement must occur between the subject DP and a low functional head for selective impairment to result. Feature underspecification, formerly considered, is rendered unnecessary.

  3. Tense Usage in Selected Humanities and Science Dissertations

    Geoffrey M. Maroko

    2014-11-01

    Full Text Available Abstract Graduate students are usually not sure of the appropriate tense to use in each rhetorical section of their dissertations in their disciplines. Even style guides provide little information regarding tense usage in academic texts. This paper describes a study in which frequency and usage of types of tense were compared in selected dissertations from the humanities and sciences drawn from Kenyan Public Universities. It was found that graduate research students in both humanities and sciences preferred the simple present and simple past as primary tense forms. It also emerged that authors have to alternate verb tenses even in the same rhetorical section of a dissertation to achieve particular communicative purposes. Suggesting that choices for tense in dissertations are a function of the epistemology and ideology of the disciplines, the paper proposes a genre-based approach to teaching those preparing to write their dissertations.

  4. Expanded tenses in the old English orosius a syntactic strengthening*

    Full Text Available The present chapter reports the investigation into certain aspects of the periphrastic construction to be +present participle (e.g. NE: "he is teaching"; OE. "he is laerende" viewed as an example of a syntactic strengthening. The construc­ tion is usually referred to as "continuous tenses/form" or "progressive tenses/form", whereas Nickel (1966 uses "expanded form". Coming closest to this latter term, the "expanded tenses" employed here seems a convenient label for two reasons: a  the use of expanded tenses is not restricted to the expression of verbal aspect (Aspekt or mode of verbal action (Aktionsart, which is implied by the use of either the term "continuous  tenses/form" or the term "progressive tenses/form"; b  the expanded tenses are integrated into the English tense system, in the sense that they can be substituted  with the respective non-expanded tenses without any change in the syntax of the clause, e.g.

  5. Aspects of cohesion, tense and pronoun usage in the discourse of the older language-impaired child

    1978-11-01

    Full Text Available Aspects of the discourse of 5 language-impaired children and 5 children with no language impairment, aged approximately 9 years, were compared. A film and a story sequence were utilised to elicit narratives on which, measures of cohesion, tense and pronouns were appraised. Measures of cohesion refer  to the ability to indicate appropriately the relations of meaning with regard to situational context. Measures of tense include aspects of tense range and tense continuity. Measures of  pronouns refer  to the anaphoric use of  pronouns with non-ambiguous referents.  The group of language-impaired children was found  to be significantly poorer on measures of  cohesion and pronominal usage than the normal children, whereas a significant difference between the two groups was not revealed on measures of tense. Possible factors  accounting for  these findings  were discussed and implications for the diagnosis and therapy of the older language-impaired child were considered.

    Full Text Available The Present Perfect Tense is a notable instance of the many quirks, “pitfalls” and inherent intricacies that can make the acquisition of English grammar quite a challenge, even with advanced students. Its dissimilarity from its possible counterparts in most European languages (including Romanian is patent. The present contribution continues the author’s preoccupation with such “False Friends” that teaching is called upon to overcome (at least, to an acceptable degree. Since the Present Perfect Tense closely incorporates tense and aspect information, while also being highly context-, and attitude-dependent, it requires conscious communicative adjustment on the part of the nonnative speaker, including the students of EFL. The grammatical category of Aspect often emerges as a linguistic “trap” for foreign learners of English, since, in Romanian, it is rendered unsystematically, mainly through specialized words, phrases, or derivational morphemes, being, in most cases, rather lexicalized (and comparatively syntax-dependent; in English aspect is a grammatical category mainly – and essentially – subordinated to the category of tense, and is usually taught as such. In this presentation, very much as in the previous one dealing with the Present Perfect and Past Tense, we considered that the most serious grammatical “trap” with respect to the use and definition of the two tenses under consideration is laid by the notion of perfectivity.

  9. Tense and Mood in Basque Nominalizations

    Directory of Open Access Journals (Sweden)

    Jon Ortiz de Urbina

    2005-06-01

    Full Text Available This article examines the role of tense and mood factors in the selection of complement clauses in Basque, arguing against apparent cases of free variation, discussed here with respect to choice of complement types. In particular, the article concentrates on the ability of some verb classes to take complements in the nominalized form. As with Spanish infinitives, the availability of nominalized complements correlates with the class membership of the main predicate into one of the subjunctive-taking groups. Apparent counterexamples, i.e., predicates which can take both a nominalized/subjunctive complement and an indicative one, will be shown to stem from differences in modality and tense. Variation is considered from a cross-linguistic perspective, and the discussion of the Basque examples is linked to 'double selection' phenomena in Spanish and Romance complements. Particular attention is paid to prospective complements, and a semantic approach is offered to explain why double selection phenomena emerge in this particular case. As expected, while the morphology of Basque and Spanish complement types is strikingly different, the semantic factors intervening in the choice and distribution of complement types will be shown not display the same degree of variation.

    Generating language that reflects the temporal organization of represented knowledge requires a language generation model that integrates contemporary theories of tense and aspect, temporal representations, and methods to plan text. This paper presents a model that produces complex sentences that reflect temporal relations present in underlying temporal concepts. The main result of this work is the successful application of constrained linguistic theories of tense and aspect to a generator which produces meaningful event combinations and selects appropriate connecting words that relate them.

  13. Past tense in the brain's time: neurophysiological evidence for dual-route processing of past-tense verbs.

    Bakker, Iske; Macgregor, Lucy J; Pulvermüller, Friedemann; Shtyrov, Yury

    2013-05-01

    A controversial issue in neuro- and psycholinguistics is whether regular past-tense forms of verbs are stored lexically or generated productively by the application of abstract combinatorial schemas, for example affixation rules. The success or failure of models in accounting for this particular issue can be used to draw more general conclusions about cognition and the degree to which abstract, symbolic representations and rules are psychologically and neurobiologically real. This debate can potentially be resolved using a neurophysiological paradigm, in which alternative predictions of the brain response patterns for lexical and syntactic processing are put to the test. We used magnetoencephalography (MEG) to record neural responses to spoken monomorphemic words ('hide'), pseudowords ('smide'), regular past-tense forms ('cried') and ungrammatical (overregularised) past-tense forms ('flied') in a passive listening oddball paradigm, in which lexically and syntactically modulated stimuli are known to elicit distinct patterns of the mismatch negativity (MMN) brain response. We observed an enhanced ('lexical') MMN to monomorphemic words relative to pseudowords, but a reversed ('syntactic') MMN to ungrammatically inflected past tenses relative to grammatical forms. This dissociation between responses to monomorphemic and bimorphemic stimuli indicates that regular past tenses are processed more similarly to syntactic sequences than to lexically stored monomorphemic words, suggesting that regular past tenses are generated productively by the application of a combinatorial scheme to their separately represented stems and affixes. We suggest discrete combinatorial neuronal assemblies, which bind classes of sequentially occurring lexical elements into morphologically complex units, as the neurobiological basis of regular past tense inflection.

    2017-07-26

    This longitudinal study investigated the emergence of English tense marking in young (Spanish-English) dual language learners (DLLs) over 4 consecutive academic semesters, addressing the need for longitudinal data on typical acquisition trajectories of English in DLL preschoolers. Language sample analysis was conducted on 139 English narrative retells elicited from 39 preschool-age (Spanish-English) DLLs (range = 39-65 months). Growth curve models captured within- and between-individual change in tense-marking accuracy over time. Tense-marking accuracy was indexed by the finite verb morphology composite and by 2 specifically developed adaptations. Individual tense markers were systematically described in terms of overall accuracy and specific error patterns. Tense-marking accuracy exhibited significant growth over time for each composite. Initially, irregular past-tense accuracy was higher than regular past-tense accuracy; over time, however, regular past-tense marking outpaced accuracy on irregular verbs. These findings suggest that young DLLs can achieve high tense-marking accuracy assuming 2 years of immersive exposure to English. Monitoring the growth in tense-marking accuracy over time and considering productive tense-marking errors as partially correct more precisely captured the emergence of English tense marking in this population with highly variable expressive language skills. https://doi.org/10.23641/asha.5176942.

    There was no difference between past perfective and present imperfective for neither group, but there was an interaction between verb class and tense for the aphasic participants, as performance in unaccusative verbs in past perfective (unmarked condition was significantly better than in unergatives in past perfective (marked condition (Z=2.512, p=0.012 but performance in unaccusatives in present imperfective (marked condition was significantly worse than performance in unergatives in present imperfective (unmarked condition (Z=2.680, p=0.004. In sum, aphasic participants performed significantly better in the unmarked than in the marked conditions. Such an interaction was not found for the SD group. Aphasic participants performed significantly worse than the SD subjects in past perfective tense (M-W U= 7.5, p=0.029 in total, and the difference was significant only for unaccusative verbs (M-W U= 6.5, p=0.021, although both groups performed very well in this condition. There was no difference in present, neither for each verb class separately nor for the total score. A general past tense deficit cannot be upheld for either group. Rather, SD participants appear relatively impaired in producing present tense. We argue for slight morphosyntactic impairment in SD, although with a different underlying cause than in aphasia. Moreover, our data suggest an effect of aspectual markedness in aphasia but not in SD. We discuss this finding in the light of the different neuropathology of the two populations.

    Full Text Available The purpose of this work is to describe the psychological characteristics of communication of forum members concerning the situation of forced separation of married couples in a situation of labor migration. Practical relevance and novelty of the work is to identify opportunities of the Internet environment for psychological support for migrant workers’ families. Through the method of content analysis of materials of the Internet forums, the motives for applying for psychological support of family members to the participants of virtual communication in the situations of labor migration are identified, the reactions of the forum members on the suggested topics are analyzed. It is noted that the actuality of applying to the Internet resources often occurs at the stage of taking a decision of labor migration, rarely - at the stage of separation, as a rule, by the remaining partner. Most forum members assess a situation of going of one of the partners to work critically, describing negative scenarios. The article deals with coping strategies described on the forum which are estimated as the point of support, the expansion of psychological experience in a situation of forced separation. The examples of adaptive, not adaptive or relatively adaptive coping mechanisms implemented by the Forum members are given. The final conclusion of the article is an overview of possibility of communication in the Internet forums to search for effective strategies for coping with the situation of forced separation due to migration.

  6. Age and the Tenses of Life Satisfaction

    Science.gov (United States)

    2013-01-01

    Objective. People have a special capacity to live simultaneously in both chronological and biographical time. In this article, we examine reports of life satisfaction that span past, present, and future, considering how perceived changes in certain life domains are associated with overall perceived life trajectories. Methods. Analyses use men and women from the Midlife Development in the United States survey. We employ gender-stratified fixed effects regression models to examine the net effect of satisfaction with finances, partnerships/marriage, sex, contribution to others, work, health, and relationship with children on trajectories of overall life satisfaction. Results. Among men, partnership and financial satisfaction had the strongest association with life satisfaction. Women displayed a somewhat broader range of domains related to their trajectories of life satisfaction. Partnership was most important, but their sense of evolving life satisfaction was also tied to their relationship with their children, sexuality, work situation, contribution to others’ welfare, and financial situation. Discussion. We find several notable differences between men and women, but the most telling differences emerge among women themselves across chronological time. For women, partner satisfaction becomes considerably more important across the age groups, whereas sex, contribution to others, and relationships with children all decrease in their importance for overall life satisfaction.

  7. RHETORICAL PATTERNS, VERB TENSE, AND VOICE IN CROSS DISCIPLINARY RESEARCH ARTICLE ABSTRACT

    Directory of Open Access Journals (Sweden)

    Sharifah Hanidar

    2016-05-01

    Full Text Available This article investigates research article abstracts in terms of their rhetorical patterns and the use of verb tenses and voice. A total of 40 abstracts were selected from four international journals in the fields of Biology, Mechanical Engineering, Linguistics, and Medicine. A four move model was adopted from Hardjanto (1997 to analyze the structure of the abstracts. The results show that all the abstracts have Move 1, creating a research space; 70% have Move 2, describing research procedure; 85% have Move 3, summarizing principal results; and 85% have Move 4, evaluating results. All the abstracts in medicine have Moves 1, 2, 3 and 4, whereas the most common pattern in Biology is Moves 1, 3 and 4, in Mechanical Engineering Moves 1, 2 and 3, and in Linguistics Moves 1, 2 and 4. This seems to suggest that there is a disciplinary variation in the structuring of RA abstracts in the four disciplines under investigation. With regard to the use of verb tense and voice in each move, the present tense and past tense in the active voice and the past tense in the passive voice were the most frequently used tenses. The present tense in the active voice was frequently used in Moves 1 and 4, while the past tense in the active voice was commonly used in Move 3 and the past tense in the passive voice was frequently found in Move 2. Furthermore, it was found that the present tense in the active voice was frequently used in Biology, Mechanical Engineering and Linguistics, whereas the past tense in the active voice occurred more frequently in Medicine, and the past tense in the passive voice was more frequently found in Mechanical Engineering than in other disciplines.

This interaction can be observed via marking the tense and mood of the sentence, or via selecting a particular type of tense, or being associated with Information Structure. Building on this fact, the current paper provides a unified analysis, in which negation in Arabic can be accounted for without a NegP projection.

  9. Rule-based learning of regular past tense in children with specific language impairment.

    Smith-Lock, Karen M

    2015-01-01

    The treatment of children with specific language impairment was used as a means to investigate whether a single- or dual-mechanism theory best conceptualizes the acquisition of English past tense. The dual-mechanism theory proposes that regular English past-tense forms are produced via a rule-based process whereas past-tense forms of irregular verbs are stored in the lexicon. Single-mechanism theories propose that both regular and irregular past-tense verbs are stored in the lexicon. Five 5-year-olds with specific language impairment received treatment for regular past tense. The children were tested on regular past-tense production and third-person singular "s" twice before treatment and once after treatment, at eight-week intervals. Treatment consisted of one-hour play-based sessions, once weekly, for eight weeks. Crucially, treatment focused on different lexical items from those in the test. Each child demonstrated significant improvement on the untreated past-tense test items after treatment, but no improvement on the untreated third-person singular "s". Generalization to untreated past-tense verbs could not be attributed to a frequency effect or to phonological similarity of trained and tested items. It is argued that the results are consistent with a dual-mechanism theory of past-tense inflection.

    Full Text Available This study sought to investigate whether there is any effect of the traditional grammar teaching on Standard Six learners’ performance in understanding and using simple present tense, simple past tense, pronouns and articles in writing. The sample for the study consisted of 40 Standard Six students of SK Tansau, Putatan, Kota Kinabalu, Sabah who was divided equally into two groups which were the treatment group and the control groups. Tests of understanding and of using the simple present tense, simple past tense, pronouns and articles were used as the instruments of the study. The data was collected through the administration of the pre-test and post-test. To analyze the collected data, the SPSS (Statistical Packages for Social Sciences version 11.5 was used. T-test was used to see if there was a significant difference in the mean of gain score. The Pearson Correlation was used on both tests between treatment group and control group to establish the relationship between scores on understanding and scores on using the grammatical features investigated. The study found that there was no significant difference in the mean of gain score in simple present tense, simple past tense and pronouns of the understanding test as well as writing test between the treatment and control groups. The results also indicated that there was no correlation between scores on test of understanding and test of using simple present tense, simple past tense, pronouns and articles on writing in the treatment group. There have been research studies in the past that lend clear cut support to the teaching of grammar as a mean of improving writing, however the results of this research clearly show that the implementation of Traditional Grammar Teaching has no effects on the students’ writing.

  19. FMRI of past tense processing: the effects of phonological complexity and task difficulty.

    2006-02-01

    The generation of regular and irregular past tense verbs has been an important issue in cognitive science and has been used to advance different models of the organization of language in the brain. The dual-system view holds that the regular past tense forms are generated by a rule while irregular forms are retrieved from memory. The single-system view, on the other hand, holds that both forms are generated by a single integrated system and differ only in their reliance on factors such as phonology and semantics. We conducted an event-related fMRI study to examine the activation patterns associated with the generation and reading of regular and irregular past tense forms, in addition to the reading of their stems. Regular and irregular past tense generation activated similar brain regions compared to the reading of their respective stems. The areas activated more for irregular generation compared to regular generation included inferior frontal, precentral, and parietal regions bilaterally. This activation can be interpreted as reflecting the greater attentional and response selection demands of irregular generation. Compared to irregular generation, regular generation activated a small region in the left superior temporal gyrus when the regular and irregular past tense forms were mismatched on phonological complexity. No areas were more activated for regulars than irregulars when the past tense forms were matched on this variable. This suggests that the activation specific to regulars was related to the higher phonological complexity of their past tense forms rather than to their generation. A contrast of the reading of regular and irregular past tense forms was consistent with this hypothesis. These results support a single-system account of past tense generation.

    2016-05-01

    Full Text Available Previous research on the acquisition of tense semantics in child Romanian has demonstrated that typically developing Romanian-speaking three-year-old children have difficulties in the comprehension and production of the imperfect (an imperfective past, and the future (Stoicescu 2013. The present study investigates whether Romanian children have difficulties with the contrasts between the present, the perfect compus (a periphrastic past, and the future. The children obtained high scores for the present in both comprehension and production. In the comprehension of the perfect compus the children performed above chance. In the comprehension and production of the future, the results were significantly lower than chance. The study provides evidence that children have an understanding of the present-past contrasts at this early age, although not at the adult level.

  2. A neuroconstructivist model of past tense development and processing.

    Westermann, Gert; Ruh, Nicolas

    2012-07-01

    We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated account of characteristic errors during learning the past tense, adult generalization to pseudoverbs, and dissociations between verbs observed after brain damage in aphasic patients. We put forward a theory of verb inflection in which a functional processing architecture develops through interactions between experience-dependent brain development and the structure of the environment, in this case, the statistical properties of verbs in the language. The outcome of this process is a structured processing system giving rise to graded dissociations between verbs that are easy and verbs that are hard to learn and process. In contrast to dual-mechanism accounts of inflection, we argue that describing dissociations as a dichotomy between regular and irregular verbs is a post hoc abstraction and is not linked to underlying processing mechanisms. We extend current single-mechanism accounts of inflection by highlighting the role of structural adaptation in development and in the formation of the adult processing system. In contrast to some single-mechanism accounts, we argue that the link between irregular inflection and verb semantics is not causal and that existing data can be explained on the basis of phonological representations alone. This work highlights the benefit of taking brain development seriously in theories of cognitive development. Copyright 2012 APA, all rights reserved.

    To analyze the situation of the vacuum in the FTU tokamak, on 22/5/96 was set up a task force to identify the problem(s) and to settle the operative and cleaning procedures. The main actions of the task force were: leak tests, automatic procedure to monitor on line the state of the machine vacuum and an exhaustive analysis of the work done before. The task force reviewed the outgassing measurements of the plastic materials inserted into the machine and was decided to repeat the test on the thermocouples. The results pointed out that the thermocouples are a practically infinite reservoir of water. The outcome of the task force was a set of new procedures and recommendations during both the operation of FTU and the shutdown periods. FTU is now operating at more acceptable plasma purity. [Italiano] Il 22/5/96 fu costituita una Task Force (TF) per analizzare le cause della `non pulizia` di FTU e per identificare le nuove procedure da seguire per la pulizia della camera da vuoto. Le azioni che la TF intraprese furono: leak tests, monitoraggio continuo dello stato del vuoto e revisione critica del lavoro fatto precedentemente. Vennero poi analizzate delle misure fatte a suo tempo sui materiali presenti nella camera da vuoto di FTU e, nel caso delle termocoppie, si decise di ripetere il test. Da questa seconda prova emerse che i cilindretti di queste termocoppie sono delle riserve inesauribili di acqua che vengono alimentate da ogni riapertura della macchina. Il lavoro della TF si concluse con una serie di procedure e raccomandazioni, da seguire prima di ogni riapertura della macchina e durante le campagne sperimentali a macchina fredda; tali procedure tengono conto del fatto che negli anni e` aumentata la quantita` di materiali plastici presenti nella camera da vuoto, soprattutto nei ports. FTU sta attualmente operando in condizioni piu` accettabili di pulizia della camera.

  4. Forced-choice decision-making in modified trolley dilemma situations: a virtual reality and eye tracking study.

    Skulmowski, Alexander; Bunge, Andreas; Kaspar, Kai; Pipa, Gordon

    2014-01-01

    Based on the frameworks of dual-process theories, we examined the interplay between intuitive and controlled cognitive processes related to moral and social judgments. In a virtual reality (VR) setting we performed an experiment investigating the progression from fast, automatic decisions towards more controlled decisions over multiple trials in the context of a sacrificing scenario. We repeatedly exposed participants to a modified ten-to-one version and to three one-to-one versions of the trolley dilemma in VR and varied avatar properties, such as their gender and ethnicity, and their orientation in space. We also investigated the influence of arousing music on decisions. Our experiment replicated the behavioral pattern observed in studies using text versions of the trolley dilemma, thereby validating the use of virtual environments in research on moral judgments. Additionally, we found a general tendency towards sacrificing male individuals which correlated with socially desirable responding. As indicated by differences in response times, the ten-to-one version of the trolley dilemma seems to be faster to decide than decisions requiring comparisons based on specific avatar properties as a result of differing moral content. Building upon research on music-based emotion induction, we used music to induce emotional arousal on a physiological level as measured by pupil diameter. We found a specific temporal signature displaying a peak in arousal around the moment of decision. This signature occurs independently of the overall arousal level. Furthermore, we found context-dependent gaze durations during sacrificing decisions, leading participants to look prolonged at their victim if they had to choose between avatars differing in gender. Our study confirmed that moral decisions can be explained within the framework of dual-process theories and shows that pupillometric measurements are a promising tool for investigating affective responses in dilemma situations.

    In 1994, the rural districts of Darmstadt-Dieburg, Bergstrasse, Odenwald and Gross-Gerau in southern Hessen and the town of Darmstadt concluded a cooperation agreement permitting them to meet the future demands of the technical code on municipal waste and the `Kreislaufwirtschafts- und Abfallgesetz` (act concerning waste recycling and waste management). In order to formally prepare different forms of cooperation and to accompany corresponding preliminary investigations, the Suedhessische Arbeitsgemeinschaft Abfallwirtschaft (SAGA) was founded as a municipal task force. SAGA`s task is to debate common affairs in the waste management sector with a view to joint planning and joint facilities. In particular, the requirements of the technical code on municipal waste must be met. (orig.) [Deutsch] Im Jahre 1994 haben die suedhessischen Landkreise Darmstadt-Dieburg, Bergstrasse, Odenwald, Gross-Gerau sowie die Stadt Darmstadt beschlossen, bezueglich der kuenftigen Anforderung der TA Siedlungsabfall und des Kreislaufwirtschafts- und Abfallgesetzes zu kooperieren. Zur formellen Vorbereitung von verschiedenen dann auszufuehrenden Kooperationsformen und zur Begleitung entsprechender Voruntersuchungen wurde die Suedhessische Arbeitsgemeinschaft Abfallwirtschaft (SAGA) als Kommunale Arbeitsgemeinschaft gegruendet. Aufgabe der Kommunalen Arbeitsgemeinschaft ist es, gemeinsam beruehrende Angelegenheiten im Abfallbereich unter dem Gesichtspunkt gemeinsamer Planung und gemeinsamer Einrichtungen zu beraten.

    Full Text Available Form-focused instruction is usually based on traditional practical/pedagogical grammar descriptions of grammatical features. The comparison of such traditional accounts with cognitive grammar (CG descriptions seems to favor CG as a basis of pedagogical rules. This is due to the insistence of CG on the meaningfulness of grammar and its detailed analyses of the meanings of particular grammatical features. The differences between traditional and CG rules/descriptions are exemplified by juxtaposing the two kinds of principles concerning the use of the present simple and present progressive to refer to situations happening or existing at speech time. The descriptions provided the bases for the instructional treatment in a quasi-experimental study exploring the effectiveness of using CG descriptions of the two tenses, and of their interplay with stative (imperfective and dynamic (perfective verbs, and comparing this effectiveness with the value of grammar teaching relying on traditional accounts found in standard pedagogical grammars. The study involved 50 participants divided into three groups, with one of them constituting the control group and the other two being experimental ones. One of the latter received treatment based on CG descriptions and the other on traditional accounts. CG-based instruction was found to be at least moderately effective in terms of fostering mostly explicit grammatical knowledge and its effectiveness turned out be comparable to that of teaching based on traditional descriptions.

    We consider an extension of bi-intuitionistic logic with the traditional modalities from tense logic Kt. Proof theoretically, this extension is obtained simply by extending an existing sequent calculus for bi-intuitionistic logic with typical inference rules for the modalities used in display logics. As it turns out, the resulting calculus, LBiKt, seems to be more basic than most intuitionistic tense or modal logics considered in the literature, in particular, those studied by Ewald and Simps...

    The ability to comprehend and represent the temporal properties of an occurrence is a crucial aspect of human language and cognition. Despite advances in neurolinguistic research into semantic processing, surprisingly little is known regarding the mechanisms which support the comprehension of temporal semantics. We used fMRI to investigate neural activity associated with processing of concrete and abstract sentences across the three temporal categories: past, present, and future. Theories of embodied cognition predict that concreteness-related activity would be evident in sensory and motor areas regardless of tense. Contrastingly, relying upon construal level theory we hypothesized that: (1) the neural markers associated with concrete language processing would appear for past and present tense sentences, but not for future sentences; (2) future tense sentences would activate intention-processing areas. Consistent with our first prediction, the results showed that activation in the parahippocampal gyrus differentiated between concrete and abstract sentences for past and present tense sentences, but not for future sentences. Not consistent with our second prediction, future tense sentences did not activate most of the regions that are implicated in the processing of intentions, but only activated the vmPFC. We discuss the implications of the current results to theories of embodied cognition and tense semantics. Copyright © 2012 Elsevier Inc. All rights reserved.

    2017-01-01

    Purpose The emergence of tense-morpheme marking during language acquisition is highly variable, which confounds the use of tense marking as a diagnostic indicator of language impairment in linguistically diverse populations. In this study, we seek to better understand tense-marking patterns in young bilingual children by comparing phonological influences on marking of 2 word-final tense morphemes. Method In spontaneous connected speech samples from 10 Spanish–English dual language learners aged 56–66 months (M = 61.7, SD = 3.4), we examined marking rates of past tense -ed and third person singular -s morphemes in different environments, using multiple measures of phonological context. Results Both morphemes were found to exhibit notably contrastive marking patterns in some contexts. Each was most sensitive to a different combination of phonological influences in the verb stem and the following word. Conclusions These findings extend existing evidence from monolingual speakers for the influence of word-final phonological context on morpheme production to a bilingual population. Further, novel findings not yet attested in previous research support an expanded consideration of phonological context in clinical decision making and future research related to word-final morphology.

    Full Text Available This study aims to determine whether the use of Climbing Grammar Mountain Game gave significant improvement on students in learning simple present tense. Classroom action research was used in this study where the data were analyzed by using quantitative and qualitative approaches. The population of the study was the students of grade eleventh at SMPN 1 Luak 50 Kota. There were 21 students in this class. Six kinds of instruments were used to collect data, namely teaching ,scenario, observation sheet, questionnaire, test, interview, and teacher’s journal. This study ran for two cycles. In the second cycle, it was shown that there was gradual improvement from the previous cycle which changed from 64 (insufficient to 79 (sufficient of the mean score. it was more than criteria of the students’ mean score which were determined in this study and it was significant because it proved that the students enthusiasm to study simple present tense, it mean that the students liked and were not bored again so this was a motivation for them to more concentrate to study simple present tense and they could use it in daily life for communication. They understand that simple present tense is important in learning English because it is used in daily life, either in writing and spoken language. It could be concluded that Climbing Grammar Mountain Game could improve the ability of the students in class VII B of SMPN 1 Luak 50 Kota in using Simple Present Tense.

    Full Text Available A way of improving on the description of the English tense system in Reichenbach [1947] is achieved by changing its matrix 3x3 design into a 2x2x2 set up, formed by 3 basic oppositions: • present vs. past • synchronous vs. posterior • incompleted vs. completed action The advantages of the binary system over the Reichenbachian ternary system are the following: • the binary system is completely compositional; • there is no tripartition between Past, Present and Future, but only the basic opposition between Past and Present remains. As we intend to show later, this is empirically supported by the Russian and Polish data; • some concrete problems, for instance, the ambiguity of past perfect with temporal adverbials or more then one configuration for the same tense form [Future Perfect [will have written] or Past Future tense [would write

    2014-07-01

    Tense operators in effect algebras play a key role for the representation of the dynamics of formally described physical systems. For this, it is important to know how to construct them on a given effect algebra and how to compute all possible pairs of tense operators on . However, we firstly need to derive a time frame which enables these constructions and computations. Hence, we usually apply a suitable set of states of the effect algebra in question. To approximate physical reality in quantum mechanics, we use only the so-called Jauch-Piron states on in our paper. To realize our constructions, we are restricted on lattice effect algebras only.

    We consider two styles of proof calculi for a family of tense logics, presented in a formalism based on nested sequents. A nested sequent can be seen as a tree of traditional single-sided sequents. Our first style of calculi is what we call "shallow calculi", where inference rules are only applied at the root node in a nested sequent. Our shallow calculi are extensions of Kashima's calculus for tense logic and share an essential characteristic with display calculi, namely, the presence of str...

  19. The winterstorm ``Vivian'' of 27 February 1990: About the meteorological development, wind forces and damage situation in the forests of Switzerland

    Schüepp, M.; Schiesser, H. H.; Huntrieser, H.; Scherrer, H. U.; Schmidtke, H.

    1994-09-01

    During the months January and February 1990 a series of severe cyclones were responsible for enormous wind-induced damage in Europe. The final of this series, on 27 February 1990, cyclone “Vivian” mainly affected the alpine valleys of Switzerland. 5 Millions m3 of timber were felled by the severe winds, a record number in this century. A complete damage survey of the deforested areas offers in combination with meteorological data an unique data set for a detailed case study of this extreme event. This paper describes the general meteorological development from the synoptic scale down to the mesoscale of Switzerland and presents a general overview of the damage situation. The main results show that a rare situation of a straight frontal zone stretching over the whole Atlantic Ocean and showing a strong gradient in temperature pointed directly toward Central-Europe. Two waves formed along this elongated polar front and deepend rapidly to depressions. The first low travelled on the southernmost trajectory of the whole storm series and affected Switzerland most. North of the Alps the prefrontal warm air was blocked to the east by the arriving coldfront and had to escape into the complex terrain of the alpine valleys. There, the stormy winds were strengthened by channelizing and “Föhn” effects. The large temperature gradient between the prefrontal and the incoming air masses induced thunderstorm activity which vortices and downdrafts might have enhanced locally. As a result most of the damaged forested areas were found between 1200 and 1600 m MSL on slopes, which were mainly exposed toward the prevailing NW-winds. A comparison of extreme wind speeds for the period 1978 1992 revealed that this event's extreme high speed of 74.5 m/s, measured at a high elevated pass station in the mountains, was exceptional. For lower elevated stations the wind speeds were high but in the range of other observed extreme values. In addition to the severe wind forces the duration

The second principle is limit the discussed issues to such a piece of reality that can be possible for precise description. The third is to avoid introducing such information to the described reality that is not explicitly mentioned by linguistic means. The authors try to following these principles in the present paper. The paper is organized as follows. First, some samples of situations related to present tense are given together with examples of their expressions in four languages: English, (as a reference language and three Slavic languages, representing South slavonic languages (Bulgarian, West slavonic languages (Polish, and East slavonic languages (Russian. Within the same framework the next parts of the paper are constructed, supplying samples of using Past tenses and, finally, future tenses and modalities. The formal tools for description purposes are introduced stepwise, according to needs caused be the described reality. There are mainly Petri nets, equipped additionally with inscriptions or labeling in order to keep proper assignations of description units to described objects.

The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society.

    Gladfelter, Allison; Leonard, Laurence B

    2013-04-01

    P. A. Hadley and H. Short (2005) developed a set of measures designed to assess the emerging diversity and productivity of tense and agreement (T/A) morpheme use by 2-year-olds. The authors extended 2 of these measures to the preschool years to evaluate their utility in distinguishing children with specific language impairment (SLI) from their typically developing (TD) peers. Spontaneous speech samples from 55 children (25 with SLI, 30 TD) at 2 different age levels (4;0-4;6 [years;months] and 5;0-5;6) were analyzed, using a traditional T/A morphology composite that assessed accuracy, and the Hadley and Short measures of Tense Marker Total (assessing diversity of T/A morpheme use) and Productivity Score (assessing productivity of major T/A categories). All 3 measures showed acceptable levels of sensitivity and specificity. In addition, similar differences in levels of productivity across T/A categories were seen in the TD and SLI groups. The Tense Marker Total and Productivity Score measures seem to have considerable utility for preschool-age children, in that they provide information about specific T/A morphemes and major T/A categories that are not distinguished using the traditional composite measure. The findings are discussed within the framework of the gradual morphosyntactic learning account.

  12. Tense, Aspect and Case in Bantu and significance in Translation- The Case of Lulogooli Bible

    Directory of Open Access Journals (Sweden)

    Joyce Imali Wangia

    2014-06-01

    Full Text Available Tense and Aspect are morphological features and in some languages like English, they are marked mainly by inflection on the verb. In Bantu languages, the verbal element is characteristically conflated to mark tense and aspect and more often than not, the morphemes marking tense and aspect cannot be isolated. In many instances, they are tonally marked. Thus, a lexical verb may mark three or even more distinctions whose semantic realization is only through tonal variation. Similarly, Case realization is unique compared to for example English that marks possession on the noun and gender distinction on pronouns. This study will examine these features in Lulogooli, a Bantu language spoken in Western Kenya. Lulogooli has only two gender distinctions; male and female but does not use pronouns to mark them. This study proposes to sample data from the Lulogooli bible translation to show why and how improper use of these three grammatical categories leads to mistranslation. The analysis will also contribute to the significance of understanding language typology to translators so as to aid accuracy and effectiveness in translation. The study posits the significance of aspects of linguistic analysis to translation.

  13. Dynamic Order Algebras as an Axiomatization of Modal and Tense Logics

    Chajda, Ivan; Paseka, Jan

    2015-12-01

    The aim of the paper is to introduce and describe tense operators in every propositional logic which is axiomatized by means of an algebra whose underlying structure is a bounded poset or even a lattice. We introduce the operators G, H, P and F without regard what propositional connectives the logic includes. For this we use the axiomatization of universal quantifiers as a starting point and we modify these axioms for our reasons. At first, we show that the operators can be recognized as modal operators and we study the pairs ( P, G) as the so-called dynamic order pairs. Further, we get constructions of these operators in the corresponding algebra provided a time frame is given. Moreover, we solve the problem of finding a time frame in the case when the tense operators are given. In particular, any tense algebra is representable in its Dedekind-MacNeille completion. Our approach is fully general, we do not relay on the logic under consideration and hence it is applicable in all the up to now known cases.

    2007-01-01

    In case of a nuclear emergency, accidental releases of radioactive material might cause large scale environmental contamination. After the emergency has been brought under control, and the radioactive releases have settled on the ground, it is essential to map as quickly as possible the extent of the contaminated area and to evaluate the severity of the contamination. Airborne gamma measurements are known to be an effective means for quickly and safely mapping and evaluating large scale contaminations of gamma-emitting radio nuclides. We wanted to integrate gamma measuring equipment, based on a NaI detector, into an Agusta A109BA helicopter of the Belgian armed forces. This was done within the framework of ''Aid to the Nation'', a special program developed by the Belgian Armed Forces for facilitating cooperation between the armed forces and civilian organisations, for projects that are to the benefit of the Belgian Nation. Working in this framework, we also want to develop the necessary procedures that will allow quick and efficient deployment of the measuring capability in case of an emergency

    Full Text Available The study aimed, firstly, to assess a group of Indonesian adult EFL students’ mastery of tenses and aspects as part of their mastery of English grammar and, secondly, to identify if their experience of going through the instructional processes, their perceptions of and habits in studying English grammar shaped their mastery of tenses and aspects. The data were collected through a grammar test and a semi-structured interview. As the study was conducted, the students were sitting in the fourth (last year of their study. Despite having such long instructional experience, however, the findings show that the mastery of tenses and aspects of majority of the students still fell into the “fail” category. Also, their having perception that studying English grammar is important apparently did not shape their mastery of tenses and aspects. What seemed influential as to shaping their mastery was much more related to their habits in studying, the modes of instruction they experienced, and the type of language samples they were exposed to, especially during the process of receiving grammar instruction in the classroom.

    Full Text Available The article addresses contrastive and narratological issues of the unity vs. diversity of temporal spheres in fictional texts. It focuses on the presentation of mimetic discourse within the past time-sphere narrative, trying to establish the narrative or stylistic functions of the present and past time-sphere verb actions with respect to the role of the narrator or that of the character. the diegetic and mimetic functions of verb actions in certain temporal spheres, ie. tense usage in (free indirect discourse (free direct discourse, will be contrastively studied in original fictional texts and their translations, in both directions between english and Slovene. the character’s mimetic discourse may be presented through different narrative forms, spanning the report-control cline from the forms “in total control” of the character, ie. free direct discourse, to that “apparently in total control” of the narrator, ie. speech act and thought act report (cf. Leech and Short 1981: 324. in addition to the character’s verbal and mental responses, the study includes mediated instances of the character’s sensory responses, the basic formula thus being: He said that/thought that/saw that. Our contrastive analysis considers only fictional texts whose diegesis is rendered   in the narrative past tenses, as the english language system observes the sequence of tenses, while the Slovene language does not. the diegesis of a fictional text may be completely located in the present time-sphere, yet such texts do not present any major issues in terms of contrastive relevance for the studied language pair.

    The current teaching trend of ESL is focused on maximizing the use of the L2 so that the student learns the language through linguistic immersion. This approach leaves the L1 out of the game, even though research has shown it can also be beneficial for the learner. My research intends to demonstrate that translation of English grammar tenses into Spanish can be a helpful way of assimilating English grammar more easily and faster, especially for those students with a poor command of English. ...

    Full text: According to our forecasts if any type of accident occurs at the nuclear power plant located on the territory of Armenian Republic the radioactive pollution will spread over the territory of Azerbaijan. The injection of radioactive substances and formation of a polluted zone on the significant area including some parts of the territory of Nakhichevan Republic, Nagorny Karabakh, Kelbajar and Kedabek regions are possible. In extraordinary situations occurred due to radiation accidents or under detection of a radioactive pollution the restriction of subsequent irradiation of the population is accomplished by protective measures. These measures are connected to the breakdown of normal live ability of the population, economic and social functioning of the territory i.e. it is an interference causing not only economic and ecological damage but also having adverse influence on the population. A decrease of risk to a possible low level (optimization) is carried out due to the following two circumstances: A time it of risk of a potential irradiation from all possible sources of radiation is regulated and for each source the boundary of risk is established; Under a decrease of potential radiation risk there is the minimum level of risk, below which a risk is considered as negligible and further decrease of risk is inexpedient. Under the accident control and under a realization of urgent reestablishment works it is recommended not to admit an equivalent dose (ED) of radiation more than approximately 500 mSv except for actions on rescue of life or on prevention of further development of the accident and the irradiation of large number of people. Assumed increase of radiation is admitted only for men older than 30 years only on voluntary written approval and preliminary informing them about possible doses of radiation at accident liquidation and about a risk for their health. The persons attracted for realization of emergency and saving work, are considered on the

  8. Complement Tense in Contrast: The SOT parameter in Russian and English

    2010-12-01

    Full Text Available In an SOT-language like English, ‘past under past’ may have a simultaneous interpretation, i.e., we have temporal agreement. In a non-SOT language like Russian, we only have the shifted interpretation. In English, the temporal morphology of the embedded verb is determined by the matrix tense via a binding chain through verbal quantifiers such as ‘say’ or ‘think’. In Russian, these attitude verbs break the binding chain. The morphology of the embedded verb is determined locally by an embedded relative PRESENT, FUTURE or PAST. We propose that the difference between English and Russian is derived from: The SOT-parameter: A language L is an SOT-language if and only if the verbal quantifiers of L transmit temporal features. Verbal quantifiers quantify over times (e.g. fut. will or world-times (e.g. verba dicendi. The paper will take up a recent challenge by Daniel Altschuler and Olga Khomitsevich against existing accounts: verbs of perception and, occasionally, factive verbs in Russian may express simultaneity by ‘past under past’. We will show that the problem is in fact non-existent when the complement is imperfective. Concerning factives, however, we argue that the complement tense is an independent de re past. Finally, perception verbs are normally not verbal quantifiers and hence not subject to the SOT-parameter.

    The Texas Low-Level Radioactive Waste Disposal Authority was formed in 1981 to address the Texas low-level radioactive waste problem consistent with the direction of P.L. 96-573. The Authority has completed technical tasks, including source term evaluations, preliminary conceptual designs, economic assessments, and long-range planning, and has work in progress on facility design, site selection, operating procedures, and licensing. Site selection has been the major technical activity and will be completed in 1987 after on-site evaluations of potential sites. The Authority expects to have its site licensed and operating in 1992. Texas has been the leader in site selection. Political concerns and the uncertainty of the national agenda led Texas policy makers to slow down the state's progress. The lessons learned through the Texas situation should be instructive to other states and compacts and may well be a prediction of events for these other groups. This paper discusses the background and status of Texas development activities, future plans, and lessons learned

    2015-09-01

    Full Text Available The introduction of dynamic assessment within sociocultural theory opened a new door toward looking at the relationship between the teaching and assessment. The dialectic relationship between the two processes provides previously unfound information regarding the assessment and the development of the learners. However, the implementation of the interactionist dynamic assessment has carried some difficulties in class in general and the groups in particular. The current study tries to address the effect of group dynamic assessment on the development of the control over the past tense; therefore, it is two-folded in the aim. Not only does it work as a practical sample of group dynamic assessment in class, but also it seeks to analyze its effect on the development of control over the past tense. To this end, three learners at the levels of elementary, low-intermediate, and intermediate general proficiency were asked to read a novel and retell the story. The dynamic intervention provided by the teacher during the story retelling was later evaluated in the transcendence tasks of writing. The Friedman test indicated that the three learners had significant development in their control over the past tense in their writing. Moreover, the qualitative analysis of the interactions suggests that the learners changed their role from the mere receivers of the teacher's mediator into the active providers of mediation to other group members. Also, they developed their understanding of the concept of the past tense through implementing it in transcendence tasks of writing.

  15. Why expressive suppression does not pay? Cognitive costs of negative emotion suppression: The mediating role of subjective tense-arousal

    Directory of Open Access Journals (Sweden)

    Szczygieł Dorota

    2015-09-01

    Full Text Available The aim of this paper was to contribute to a broader understanding of the cognitive consequences of expressive suppression. Specifically, we examined whether the deteriorating effect of expressive suppression on cognitive functioning is caused by tense arousal enhanced by suppression. Two experiments were performed in order to test this prediction. In both studies we tested the effect of expressive suppression on working memory, as measured with a backwards digit-span task (Study 1, N = 43 and anagram problem-solving task (Study 2, N = 60. In addition, in Study 2 we tested whether expressive suppression degrades memory of the events that emerged during the period of expressive suppression. Both studies were conducted in a similar design: Participants watched a film clip which evoked negative emotions (i.e. disgust in Study 1 and a combination of sadness and anxiety in Study 2 under the instruction to suppress those negative emotions or (in the control condition to simply watch the film. The results of these experiments lead to three conclusions. First, the results reveal that expressive suppression degrades memory of the events that emerged during the period of expressive suppression and leads to poorer performance on working memory tasks, as measured with a backwards digit-span task and anagram problem-solving task. Second, the results indicate that expressive suppression leads to a significant increase in subjective tense arousal. Third, the results support our prediction that expressive suppression decreases cognitive performance through its effects on subjective tense arousal. The results of the Study 1 show that tense arousal activated during expressive suppression of disgust fully mediates the negative effect of suppression on working memory as measured with a backwards digit-span task. The results of Study 2 reveal that subjective tense arousal elicited while suppressing sadness and anxiety mediates both the effect of suppression on

    2018-01-01

    Full Text Available Formation of model describing dynamic straining of reinforced concrete requires taking into account the basic aspects influencing the stress-strain state of structures. Strength of concrete segments in crack spacing is one of the crucial aspects that affect general strain behavior of reinforced concrete. Experimental results demonstrate significant change in strength of tensed and compressed concrete segments in crack spacing both under static and under dynamic loading. In this case, strength depends on tensile strain level and the slope angle of rebars towards the cracks direction. Existing theoretical and experimental studies estimate strength of concrete segments in crack spacing under static loading. The present work presents results of experimental and theoretical studies of dynamic strength of plates between cracks subjected to compression-tension. Experimental data was analyzed statistically; the dependences were suggested to describe dynamic strength of concrete segments depending on tensile strain level and slope angle of rebars to cracks direction.

  17. Tense and aspect in word problems about motion: diagram, gesture, and the felt experience of time

    de Freitas, Elizabeth; Zolkower, Betina

    2015-09-01

    Word problems about motion contain various conjugated verb forms. As students and teachers grapple with such word problems, they jointly operationalize diagrams, gestures, and language. Drawing on findings from a 3-year research project examining the social semiotics of classroom interaction, we show how teachers and students use gesture and diagram to make sense of complex verb forms in such word problems. We focus on the grammatical category of "aspect" for how it broadens the concept of verb tense. Aspect conveys duration and completion or frequency of an event. The aspect of a verb defines its temporal flow (or lack thereof) and the location of a vantage point for making sense of this durational process.

    Full Text Available In this paper, I claim that the so-called present perfect puzzle is, in reality, a puzzle about the simple past. It is the latter, I argue, that shows a puzzling behavior, given that it can be used not only in definite contexts but also in seemingly indefinite ones. I employ the notions of time frame and specifiability to show how the obvious distinction between the two tenses in terms of temporal logic can be accounted for. I also propose that the past morpheme -ed be considered a kind of verb determiner which selects a temporal XP as a complement. Such complement can be (and usually is expressed either in the sentence or in the larger discourse; however, it can also remain implicit, or covert.

  19. Situation awareness system for Canada

    Hill, Andrew

    1999-07-01

    Situation awareness encompasses a knowledge of orders, plans and current knowledge of friendly force actions. Knowing where you are and being able to transmit that information in near real-time to other friendly forces provides the ability to exercise precise command and control over those forces. With respect to current command and control using voice methods, between 40 percent and 60 percent of Combat Net Radio traffic relates to location reporting of some sort. Commanders at Battle Group and below spend, on average, 40 percent of their total time performing position and navigation related functions. The need to rapidly transfer own force location information throughout a force and to process the received information quickly, accurately and reliably provides the rationale for the requirement for an automated situation awareness system. This paper describes the Situation Awareness System (SAS) being developed by Computing Devices Canada for the Canadian Department of National Defence as a component of the Position Determination and Navigation for Land Forces program. The SAS is being integrated with the Iris Tactical Command, Control, Communications System, which is also being developed by Computing Devices. The SAS software provides a core operating environment onto which command and control functionality can be easily added to produce general and specialist battlefield management systems.

  20. Muscle tension increases impact force but decreases energy absorption and pain during visco-elastic impacts to human thighs.

    Tsui, Felix; Pain, Matthew T G

    2018-01-23

    Despite uncertainty of its exact role, muscle tension has shown an ability to alter human biomechanical response and may have the ability to reduce impact injury severity. The aim of this study was to examine the effects of muscle tension on human impact response in terms of force and energy absorbed and the subjects' perceptions of pain. Seven male martial artists had a 3.9 kg medicine ball dropped vertically from seven different heights, 1.0-1.6 m in equal increments, onto their right thigh. Subjects were instructed to either relax or tense the quadriceps via knee extension (≥60% MVC) prior to each impact. F-scan pressure insoles sampling at 500 Hz recorded impact force and video was recorded at 1000 Hz to determine energy loss from the medicine ball during impact. Across all impacts force was 11% higher, energy absorption was 15% lower and time to peak force was 11% lower whilst perceived impact intensity was significantly lower when tensed. Whether muscle is tensed or not had a significant and meaningful effect on perceived discomfort. However, it did not relate to impact force between conditions and so tensing may alter localised injury risk during human on human type impacts. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Grammar is the description of the ways in which words are formed and can change their form and can be combined into sentences in order to express different meanings.The students need ability how to have a good grammar especially in simple past tense. Simple past tense is the form of a verb used to describe actions in the past. After knowing the highly complex grammar especially in simple past tense, teacher needs to move to how to select the materials and activities to be used in grammar class. One of techniques used in teaching grammar is Team Assisted Individualization technique, Team Assisted Individualization technique belongs to the cooperative learning. Team Assisted Individualization technique is a technique in which the students are placed into the small groups and then followed by the giving the help individually for the student who need it. The score “t” at the signifcance level of 5%, the calculation t-count is 9.49, and the value of “t” on the t-table with the signifcance 5% with the value of Df = 50, it can be found that t-table = 2.01. It means that there is difference grammar score between experimental and control class. Based on the explanation above, the Team Assisted Individualization technique surely shows the real effectiveness.

  3. L1 French learning of L2 Spanish past tenses: L1 transfer versus aspect and interface issues

    Directory of Open Access Journals (Sweden)

    José Amenós Pons

    2017-09-01

    Full Text Available This paper examines the process of acquiring L2s that are closely related to the L1 through data on how adult French speakers learning L2 Spanish in a formal setting develop knowledge and use of past tenses in this L2. We consider the role of transfer and simplification in acquiring mental representations of the L2 grammar, specifically in the area of tense and aspect, and how learners deal with integrating grammatically encoded, lexical and discursive information, including mismatching feature combinations leading to particular inferential effects on interpretation. Data is presented on the Spanish past tenses (simple and compound past, pluperfect, imperfect and progressive forms from two tasks, an oral production filmretell and a multiple-choice interpretation task, completed by learners at A2, B1, B2 and C1 CEFR levels (N = 20-24 per level. L1 influence is progressively attenuated as proficiency increases. Difficulties were not always due to negative L1 transfer, but related also to grammar-discourse interface issues when integrating linguistic and pragmatic information in the interpretation process. This has clear implications for the teaching of closely related languages: instruction should not only focus on crosslinguistic contrasts, but also prioritize uses requiring complex interface integration, which are harder to process.

    2018-03-01

    Full Text Available The current study aimed at the comparative effect of inter-sentential vs intra-sentential code-switching on learning past tense. Initially, through non-random convenient sampling, the researcher chose 90 female EFL learners at the elementary level. Next, Key English Test (KET was administered to the 90 learners and the results were used to select 60 participants for the purpose of this study. The participants were then divided into two groups each consisting of 30 learners. Afterwards, a grammar pretest having 30 items focusing on past simple tense was given to both groups. Following that, the grammatical explanations were provided for the two groups for ten sessions using code-switching.  The first experimental group received inter-sentential code switching in line with Reyes’s (2004 as a switch between two languages, where a sentence in one of the languages is completed and the next sentence starts with the other language (Reyes, 2004. In the second experimental group, in line with Reyes’s (2004, the switching occurred within a sentence. The results of statistical analysis indicated that inter-sentential code-switching proved more effective compared to intra-sentential code-switching on the learning of past tense by EFL learners. Based on the findings of the present study, EFL teachers are encouraged to use inter-sentential code-switching more compared to intra-sentential code-switching when it comes to teaching grammar.

  5. Cognition, Grammaticalization and Syntactic Change. The emergence of Compound Tenses in Portuguese

    Directory of Open Access Journals (Sweden)

    Maria José Carvalho

    2013-11-01

    Full Text Available This article analyzes the historical process of the grammaticalization of aver/ter ‘to have’ in compound tenses, since Portuguese is somewhat isolated among Romance languages in this respect. Our research has shown that the change in auer/ter, from indicating possession to acting as auxiliaries, involved a process of recategorization similar to that seen with the verbs “go”, “come” and “have” in some languages, sharing with them a fundamental characteristic: the fact that in one phase of the transition constructions developed which were capable of being interpreted in both ways (expressing both result and time. Thus, as in those languages, the process of recategorizing involves an intermediate step of structural ambiguity whereby a given construction can be interpreted in two different ways. We will try to clarify the gradual process of reanalysis of ter in the medieval period, based on a corpus of original juridical sources (13th – 16th centuries which we have transcribed, originating from a particularly important centre in medieval Portuguese culture, the monastery of Alcobaça (between Coimbra and Lisbon. The corpus consists of 153 original documents not only from the monastery but also from the outlying areas under its jurisdiction, dating from between 1289 and 1565.

  7. A combination of high stress-induced tense and energetic arousal compensates for impairing effects of stress on memory retrieval in men.

    Boehringer, Andreas; Schwabe, Lars; Schachinger, Hartmut

    2010-09-01

    Stress can both impair and enhance memory retrieval. Glucocorticoids mediate impairing effects of stress on memory retrieval. Little is known, however, about factors that facilitate post-stress memory performance. Here, we asked whether stress-induced arousal mediates facilitative stress effects on memory retrieval. Two arousal dimensions were separated: tense arousal, which is characterized by feelings ranging from tension and anxiety to calmness and quietness, and energetic arousal, which is associated with feelings ranging from energy and vigor to states of fatigue and tiredness. Fifty-one men (mean age +/- SEM: 24.57 +/- 0.61 years) learned emotional and neutral words. Memory for these words was tested 165 min later, after participants were exposed to a psychosocial stress or a non-arousing control condition. Changes in heart rate, self-reported (energetic and tense) arousal, and saliva cortisol in response to the stress/control condition were measured. Overall, stress impaired memory retrieval. However, stressed participants with large increases in both tense and energetic arousal performed comparably to controls. Neither salivary cortisol level nor autonomic arousal predicted memory performance after controlling for changes in energetic and tense arousal. The present data indicate that stress-induced concurrent changes in tense and energetic arousal can compensate for impairing effects of stress on memory retrieval. This finding could help to explain some of the discrepancies in the literature on stress and memory.

    The phonological and morphosyntactic structures of English and Mandarin contrast maximally and an increasing number of bilinguals speak these two languages. Speech and language therapists need to understand bilingual development for children speaking these languages in order reliably to assess and provide intervention for this population. To examine the marking of verb tense in the English of two groups of bilingual pre-schoolers learning these languages in a multilingual setting where the main educational language is English. The main research question addressed was: are there differences in the rate and pattern of acquisition of verb-tense marking for English-language 1 children compared with Mandarin-language 1 children? Spoken language samples in English from 481 English-Mandarin bilingual children were elicited using a 10-item action picture test and analysed for each child's use of verb tense markers: present progressive '-ing', regular past tense '-ed', third-person singular '-s', and irregular past tense and irregular past-participle forms. For 4-6 year olds the use of inflectional markers by the different language dominance groups was compared statistically using non-parametric tests. This study provides further evidence that bilingual language development is not the same as monolingual language development. The results show that there are very different rates and patterns of verb-tense marking in English for English-language 1 and Mandarin-language 1 children. Furthermore, they show that bilingual language development in English in Singapore is not the same as monolingual language development in English, and that there are differences in development depending on language dominance. Valid and reliable assessment of bilingual children's language skills needs to consider the characteristics of all languages spoken, obtaining accurate information on language use over time and accurately establishing language dominance is essential in order to make a

    the mistakes of some of the grammars. This research project has for the first time introduced constructive models of compound sentences in a comprehensive research taking in to account the tense of the verbs. The primary question in this research project is which kind of sentences can be considered as compound and what is the constructive of such a sentence? When defining a compound sentences, grammarians either shave the same beliefs or differ in their ideas. But all grammarians agree to the fact that a compound sentences has more than one verb. Different definitions are due to different criteria adapted in constructing a compound sentences. To construct a noun, and adjective, a verb and a sentence we should take similar and precise criteria to our consideration. In the grammatical units of noun, adjectives, and verbs construction means connecting two or more parts that can convey one similar meaning and its parts are dependent upon one another.  In the construction of compound sentences there must be the same criteria so that its applications can be truly recognized and identified just like the previously mentioned grammatical units. The first step to arrive at a criterion in defining and identifying compound sentences, is to separate this discussion from connective sentences that are relate to each other with connectives are called connective sentences. But sentences which are constructed with dependent making connectives and their parts are dependent upon one another are called compound sentences. Therefore the signs of compound sentences with regard to constructions and the meaning of criterion are as follows: 1 They have more than one verb. 2 The consistence of two or more dependent phrases. 3 Phrases construct a complete sentences all together and convey one similar message. 4 One of the phrases is the main clause and the other one is the subordinate one. 5 The phrases or subordinate clauses can be related to one of the major parts and they can take a

    2014-12-01

    Full Text Available Marine traffic engineering has been pushed to the limits due to a rising demand in the shipping business. Merchant ships are growing dramatically, both in numbers and in size. To keep pace with current developments, automation seems to be one viable option when it comes to keeping ships running with fewer seafarers available. The aim of this paper is to monitor a modern day mariners’ performance while working in a tense situation. The objective is to define the size of the safety domain whilst overtaking a vessel. The approach was to assess the ship's domain area within a 3 nm wide traffic separation scheme by using a ship handling simulator. From the simulation results, an overtaking domain was determined as 1.36 nm long and 0.4 nm wide. Safety domains in real-life situations were experienced on a much smaller scale compared to the previous findings. The working load for this particular operation is expected to be stressful and highly skilled orientated.

  6. Reference and discursive roles of the verbal paradigm future tense (futuro simples do indicativo in Brazilian Portuguese in the narrative text Budapest

    Directory of Open Access Journals (Sweden)

    Blažka Müller Pograjc

    2017-12-01

    Although Budapest is a narrative text which is particularly marked by the verbal paradigms of the past series, in four text sequences seven occurrences of the future are present. Based on an analysis of these sequences, it could be claimed that the occurrence of the future tense signals that the narrative is oriented to the present sphere of the narrator, and thus to a moment of storytelling. By considering this transition, characterized also by the presence of the future tense marking the temporal values of ‘futurity’ and the modal values of ‘certainty’ and ‘non-realisation’, it can be observed that it occurs in the text sequences of Budapest within various narrative strategies. There is thus to be considered the transition from the narration to the description, the description in the descriptive sequence, and the dialogues in the dialogue fragment when the narrator uses the process of integrating the direct discourse of the protagonists in the narration.

  8. Situational theory of leadership.

    Science.gov (United States)

    Waller, D J; Smith, S R; Warnock, J T

    1989-11-01

    The situational theory of leadership and the LEAD instruments for determining leadership style are explained, and the application of the situational leadership theory to the process of planning for and implementing organizational change is described. Early studies of leadership style identified two basic leadership styles: the task-oriented autocratic style and the relationship-oriented democratic style. Subsequent research found that most leaders exhibited one of four combinations of task and relationship behaviors. The situational leadership theory holds that the difference between the effectiveness and ineffectiveness of the four leadership styles is the appropriateness of the leader's behavior to the particular situation in which it is used. The task maturity of the individual or group being led must also be accounted for; follower readiness is defined in terms of the capacity to set high but attainable goals, willingness or ability to accept responsibility, and possession of the necessary education or experience for a specific task. A person's leadership style, range, and adaptability can be determined from the LEADSelf and LEADOther questionnaires. By applying the principles of the situational leadership theory and adapting their managerial styles to specific tasks and levels of follower maturity, the authors were successful in implementing 24-hour pharmacokinetic dosing services provided by staff pharmacists with little previous experience in clinical services. The situational leadership model enables a leader to identify a task, set goals, determine the task maturity of the individual or group, select an appropriate leadership style, and modify the style as change occurs. Pharmacy managers can use this model when implementing clinical pharmacy services.

    Full Text Available Textual manipulation is a common pedagogic tool used to emphasize specific features of a second language (L2 text, thereby facilitating noticing and, ideally, second language development. Visual input enhancement has been used to investigate the effects of highlighting specific grammatical structures in a text. The current study uses a quasi-experimental design to determine the extent to which textual manipulation increase (a learners’ perception of targeted forms and (b their knowledge of the forms. Input enhancement was used to highlight the Spanish preterit and imperfect verb forms and an eye tracker measured the frequency and duration of participants’ fixation on the targeted items. In addition, pretests and posttests of the Spanish past tense provided information about participants’ knowledge of the targeted forms. Results indicate that learners were aware of the highlighted grammatical forms in the text; however, there was no difference in the amount of attention between the enhanced and unenhanced groups. In addition, both groups improved in their knowledge of the L2 forms; however, again, there was no differential improvement between the two groups.

    Full Text Available In studies based on the theme of languages in/of contact, the process of language acquisition is treated as a relative process, which involves many factors determined by the context of acquisition and of topical and dynamic uses of languages in different communicative environments. In these studies it is possible to identify that next to sociolinguistic and sociocultural factors, other factors established by structural and conceptual dimensions also emanate as relevant to the process of acquisition and use of languages. In this project we united the paradigm of the Sociolinguistics to the paradigm of the Contrastive Linguistics (Kontrastive Linguistik, more precisely of the Contrastive Grammar, in interaction with the Contrastive Culture (Kulturkontrastive Grammatik. The object of our study is the form and the functionality of verbal forms in German and Portuguese.

    DEFF Research Database (Denmark)

    Lystbæk, Christian Tang

    The purpose of this paper is to examine ways to situate management within philosophy, that is, ways to analyze the philosophical assumptions in management history, theory and practice. Since Burrell and Morgan suggested the idea that “all theories of organization are based upon philosophy...... of science“ (Burrell & Morgan, 1979:1), philosophical reflections in terms of a series of “isms” informed by different schools or paradigms (such as positivism, structuralism, phenomenology, critical theory, and so on and so forth) have been a central part of management studies. Thus, today, it has become...... common sense to categorize different approaches to management according to their assumptions of ontology, epistemology and methodology. My paper will argue first (1) that, although sometimes very abstract and obtuse writing that seems to owe more to competition among academics than to illumination...

    Considerations related to the early planning for the International Magnetospheric Study (IMS) took into account the desirability of an establishment of specific entities for generating and disseminating coordination information for both retrospective and predictive periods. The organizations established include the IMS/Satellite Situation Center (IMS/SSC) operated by NASA. The activities of the SSC are related to the preparation of reports on predicted and actually achieved satellite positions, the response to inquiries, the compilation of information on satellite experiments, and the issue of periodic status summaries. Attention is given to high-altitude satellite services, other correlative satellite services, non-IMS activities of the SSC, a summary of the SSC request activity, and post-IMS and future activities

    Full Text Available In this paper we analyzed the cirumstances of every day life which requires the need to adapt the leadership style. Leadership needs a lot of abilities and skills, including the capability to communicate. The paper deals with leader’s need of changing the style of leading as organizational circumstances change. The process is efficient only when the leaders and the followers have the right climate. The importance of this process is reflected in the productivity of the organization. As the economic climate changes the leadership style needs to be changed and also the style of communication throughout the leader coaches, coordinates, evaluates and supervises. Leadership is about organizing a group of people to achieve a goal. The leader may or may not have any formal authority. Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. This paper describes the styles of leadership which the leaders must use and switch when is needed in comparison with what leadership is about.

  7. Preparing for Emergency Situations

    2010-11-01

    Disaster relief can be seen as a dynamic multi actor process with actors both joining and leaving the relief work during the help and rescue phase after the disaster has occurred. Actors may be governmental agencies, non profit voluntary organisations or spontaneous helpers comprised of individual citizens or temporal groups of citizens. Hence, they will vary widely in agility, competence, resources, and endurance. To prepare for for disasters a net based Agora with simulation of emergency situations for mutual preparation, training, and organisational learning is suggested. Such an Agora will ensure future security by: -Rising awareness and preparedness of potential disaster responders by help of the components and resources in the netAgora environment; -Improving cooperation and coordination between responders; -Improving competence and performance of organisations involved in security issues; -Bridging cultural differences between responders from different organizations and different backgrounds. The developed models are intended to reflect intelligent anticipatory systems for human operator anticipation of future consequences. As a way to catch what should be included in this netbased Agora and to join the split pictures that is present, Team Syntegrity could be a helpful tool. The purpose of Team Syntegrity is to stimulate collaboration and incite cross fertilization and creativity. The difference between syntegration and other group work is that the participants are evenly and uniquely distributed and will collectively have the means, the knowledge, the experience, the perspectives, and the expertise, to deal with the topic. In this paper the possibilities with using Team Syntegrity in preparation for the development of a netbased Agora is discussed. We have identified that Team Syntegrity could be useful in the steps User Integration, Designing the netAgora environment, developing Test Scenarios, and assessment of netAgora environment.

    2016-07-01

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

    This book is the result of a study into the future energy situation in the Netherlands, performed by the electricity companies in the country. The first five chapters sketch the framework within which energy policy is currently forced to operate. Further technical and physical conditions are considered in the following six chapters, including environmental and safety aspects. A prognosis for energy demand in the Netherlands until the end of the century is presented and five different scenarios are discussed, as means of supplying this demand. Nuclear energy is one of the sources considered throughout the text. (C.F.)

    Claudio Salmeri

    2013-01-01

    Full Text Available The purpose of this paper is to present a comparative analysis of a novel written in Italian by Laura Mancinelli, 'The Twelve Abbots of Challant', and its translation into Polish prepared by Maciej Brzozowski. Focusing on a few examples, such as the use of grammatical tenses and moods, differences in the syntax, and the problems of translating idiomatic and metaphoric expressions, the paper aims to compare the author’s style with that of the translator. The task undertaken by the translator seems very hard indeed from the very beginning due to considerable differences between the Italian and Polish languages in the use of tenses and moods. While the Italian grammar uses four moods, eight simple and seven compound tenses, the frugal Polish grammar makes with just three modes, one compound and three simple tenses. The discussion will clearly illustrate that thanks to some modifications it was possible to translate and preserve the meaning and the spirit of the Italian grammar and style.

For this reason, ESO has until now been silent in these matters, but we have now become obliged to make our opinion known". The ESO representative also made it clear, that "ESO does not question the rights of the claimants to recur to the Chilean Tribunals which must decide on the matter of ownership, and that ESO cannot be party to this lawsuit". He added that "ESO fully trusts that the Chilean Government will do whatever is necessary to defend the immunity of ESO". THE CURRENT SITUATION During the past few days, declarations from high officials at the Chilean Ministry of Foreign Affairs have been made which clearly confirm ESO's immunity of jurisdiction from Chilean Courts. The same opinion has been ventured by Chilean experts in international law, quoted in various Chilean newspapers. On Friday, February 17, the Chilean Minister of Foreign Affairs, Mr. Jose M. Insulza, made a similar, very eloquent statement. ESO welcomes these articulate expressions that support its official position and trusts that the current situation will be speedily resolved by the competent Chilean authorities, so that the construction work at Paranal will not be stopped. During the past three decades, ESO's presence in Chile has been characterised by good relations to all sides. The development of astronomy in Chile during the past decades has reached such a level that it will now benefit from a new quality of cooperation. In addition to its past and numerous services to Chilean astronomy, ESO has recently considered to establish a "guaranteed" observing time for astronomers from this country, both at La Silla and the future VLT observatory on Paranal. With a proposed 10 percent quota for the VLT, Chilean astronomers will in fact have free access to the equivalent of 40 percent of one 8.2-metre telescope; the associated, not insignificant cost is entirely carried by ESO. ESO has also considered to incorporate

    Since 9 March 2006 the United Nations Security Council has been examining the report on Iran by the IAEA, which noted the failure of years of negotiations between Iran and the EU3 nations representing Europe (Britain, France and Germany). Following the June 2005 election of Mr Ahmadinejad, relations with the international community have become notably tense, with the resumption of nuclear activity (reprocessing, enrichment, etc.). The West is now convinced that this civil programme is enabling Iran to conceal a military programme, which, if it is completed, will shatter relationships, political and economic, in an area of strategic importance. The tensions generated by the policy adopted by Iran, in its forced march towards a nuclear capability, brings to the fore the nuclear proliferation problem, which is likely to become one of the major threats of the twenty-first century.

    Buhmann, Stefan Yoshi

    2012-01-01

    In this book, a modern unified theory of dispersion forces on atoms and bodies is presented which covers a broad range of advanced aspects and scenarios. Macroscopic quantum electrodynamics is shown to provide a powerful framework for dispersion forces which allows for discussing general properties like their non-additivity and the relation between microscopic and macroscopic interactions. It is demonstrated how the general results can be used to obtain dispersion forces on atoms in the presence of bodies of various shapes and materials. Starting with a brief recapitulation of volume I, this volume II deals especially with bodies of irregular shapes, universal scaling laws, dynamical forces on excited atoms, enhanced forces in cavity quantum electrodynamics, non-equilibrium forces in thermal environments and quantum friction. The book gives both the specialist and those new to the field a thorough overview over recent results in the field. It provides a toolbox for studying dispersion forces in various contex...

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society. We propose you of to know more about it in this file. (N.C.)

    The Ehrenfest force in an inhomogeneous magnetic field is calculated. It is shown that there exist such (very rare) topologically nontrivial physical situations when the Gauss theorem in its classic formulation fails and, as a consequence, apart from the usual Lorentz force an additional, purely imaginary force acts on the charged particle. This force arises only in inhomogeneous magnetic fields of special configurations, has a purely quantum origin, and disappears in the classical limit

    2015-01-01

    This publication proposes an overview of the situation of the Fukushima-Daiichi nuclear power station, four years after the accident. It addresses how the situation is managed in terms of evacuation of nuclear fuels, of storage of contaminated water, and of temporary storage of radioactive wastes produced by decontamination activities. It addresses the decontamination of the environment and the return of populations: progress of decontamination, return of populations, and absence of contamination of food products. The next part addresses the perspectives for the Japanese nuclear sector: a strengthened nuclear safety authority, reactors ready to start up again (some reactors seem to be able to be authorized to soon start up again). It describes how French technology is involved at the service of Fukushima-Daiichi through the Onet Technologies project by the CEA (a remote controlled laser cutting process). It evokes the evolutions of safety requirements in France after the Fukushima accident, notably with the introduction of the hard core notion, and of the FARN or Fast Nuclear Task Force

  1. [Support psychotherapy in traumatic situations].

    Science.gov (United States)

    Pérez-Sales, Pau; Vázquez Valverde, Carmelo

    2003-12-01

    It seems that a certain consensus exists to speak about a traumatic situation as an experience which is made up of a threat on the physical or psychological integrity of a person and against which one responds with fear, desperation and intensive horror. Different psychological phenomena are involved with the manner through which a human being confronts his/her past. In particular, the response to traumatic situations, mourning, and blame share their characteristic of being an irreversible living reality related to facts, loss or past impacts and it is necessary to integrate these in one's life in order to advance; these comprise a triangle frequently coexisting and interconnected. Aid for these three situations has, therefore, as common elements, two premises: an active task is required by the person who suffers this situation; this person must, in some form, desire to move ahead. One can not toil in mourning, in a traumatic experience, or in a life of blame if these have a positive symbolic value for this person; for example, mourning as a manner not to treason the dead person by forgetting that person, the reliving a trauma as an attempt to provide some sense to the actions which occurred, or blame as a desire to not forget an error or as a final punishment of this active task; the final objective of this active task is not usually to forget but to integrate in order to live. If a person does not perceive this clearly, this person may not become actively involved in the task to overcome a traumatic situation and to move ahead, nor will that person accept that a person who tries to help questions this person's realities or experiences.

    Full Text Available The purpose of this study is to analyze factors contributing to errors made in learning English as a target language (TL. Employing a case study research, the participant was interviewed for approximately 30 minutes about daily activities and experiences in learning English. This research focuses in analysing the participant‟s use of third singular pronoun in simple present tense. The findings revealed that errors made by TL learners are mainly influenced by some factorsrelated to their TL‟s and native language‟s (NL knowledge, systems and rules. These factors are coexisted and interconnected in TL learners‟ minds. This is against Robert Lado‟s argument which mentioned that learner made errors in TL learning because of the interference from NL. The study provides pedagogical implications that TL teachers should perceive errors made by the learners as a sign of language learning and development; therefore they should not be discouraged to learn. Also, TL teachers should be aware of their very important roles to help, to guide and to lead the learners‟ progress in learning the TL. The future subsequent studies should consider of involving more sample size over a longer period of time as to obtain to a more generalized finding.

  4. The relationship between native allophonic experience with vowel duration and perception of the English tense/lax vowel contrast by Spanish and Russian listeners.

    2008-12-01

    Two studies explored the role of native language use of an acoustic cue, vowel duration, in both native and non-native contexts in order to test the hypothesis that non-native listeners' reliance on vowel duration instead of vowel quality to distinguish the English tense/lax vowel contrast could be explained by the role of duration as a cue in native phonological contrasts. In the first experiment, native Russian, Spanish, and American English listeners identified stimuli from a beat/bit continuum varying in nine perceptually equal spectral and duration steps. English listeners relied predominantly on spectrum, but showed some reliance on duration. Russian and Spanish speakers relied entirely on duration. In the second experiment, three tests examined listeners' use of vowel duration in native contrasts. Duration was equally important for the perception of lexical stress for all three groups. However, English listeners relied more on duration as a cue to postvocalic consonant voicing than did native Spanish or Russian listeners, and Spanish listeners relied on duration more than did Russian listeners. Results suggest that, although allophonic experience may contribute to cross-language perceptual patterns, other factors such as the application of statistical learning mechanisms and the influence of language-independent psychoacoustic proclivities cannot be ruled out.

  5. Situational Strength Cues from Social Sources at Work: Relative Importance and Mediated Effects.

    Situational strength is considered one of the most important situational forces at work because it can attenuate the personality-performance relationship. Although organizational scholars have studied the consequences of situational strength, they have paid little attention to its antecedents. To address this gap, the current study focused on situational strength cues from different social sources as antecedents of overall situational strength at work. Specifically, we examined how employees combine situational strength cues emanating from three social sources (i.e., coworkers, the immediate supervisor, and top management). Based on field theory, we hypothesized that the effect of situational strength from coworkers and immediate supervisors (i.e., proximal sources of situational strength) on employees' perceptions of overall situational strength on the job would be greater than the effect of situational strength from the top management (i.e., the distal source of situational strength). We also hypothesized that the effect of situational strength from the distal source would be mediated by the effects of situational strength from the proximal sources. Data from 363 full-time employees were collected at two time points with a cross-lagged panel design. The former hypothesis was supported for one of the two situational strength facets studied. The latter hypothesis was fully supported.

    In the field of emergency procedures regarding the protection of life, property and the environment, the 'prefet' of a department is the only public authority both representative of the state and accountable. In France laws and regulations have been in recent years revised in order to modernize emergency situations management. The 'prefet' of the Drome 'department', Henri MASSE, presents a summary of recent developments and explains how his services are organised in order to be able to handle emergency situations. He also focuses on his experience of handling the specific difficulties of nuclear risks, his department sheltering numerous nuclear facilities: EURODIF Pierrelatte nuclear fuel enrichment plant, EDF Tricastin nuclear power plant, AREVA Valence FBFC nuclear fuel manufacturing unit, etc. (author)

    In this paper the present status of the meson theory of nuclear forces is reviewed. After some introductory remarks about the relevance of the meson exchange concept in the era of QCD and the empirical features of the NN interaction, the exciting history of nuclear forces is briefly outlined. In the main part, the author gives the basic physical ideas and sketch the derivation of the one-boson-exchange model of the nuclear force, in the Feynman approach. Secondly we describe, in a qualitative way, various necessary extensions, leading to the Bonn model of the N interaction. Finally, points to some interesting pen questions connected with the extended quark structure of the hadrons, which are topics of current research activity

  12. Fundamental situations in teaching biology: The case of parthenogenesis

    Directory of Open Access Journals (Sweden)

    Robert Evans

    2012-06-01

    Full Text Available This theoretical paper considers the notion of fundamental situation in the sense of Brousseau’s theory of didactical situations. It introduces some precise elements of this theory in which a teacher provides an environment for student work that aims to enable students, through constructive inquiry, to acquire well defined pieces of scientific knowledge. Situations become fundamental if they not only allow, but force students to construct the target knowledge. A classical example from mathematics is presented, where the target knowledge is a theorem of plane geometry presented as a puzzle. Then a new fundamental situation in biology is described for parthenogenetic reproduction, which has recently turned out to occur in Komodo dragons. An explicit demand to generate and test hypotheses that could explain the given example of dragon reproduction, using authentic DNA data, is given to students. The paper concludes with an analysis of the extent to which this fundamental situation in biology is authentic to the theory of didactical situations.

    Abramowicz, M.A.; Max-Planck-Institut fuer Physik und Astrophysik, Garching

    1990-01-01

    The need for a rather fundamental revision in understanding of the nature of the centrifugal force is discussed. It is shown that in general relativity (and contrary to the situation in Newtonian theory) rotation of a reference frame is a necessary but not sufficient condition for the centrifugal force to appear. A sufficient condition for its appearance, in the instantaneously corotating reference frame of a particle, is that the particle motion in space (observed in the global rest frame) differs from a photon trajectory. The direction of the force is the same as that of the gradient of the effective potential for photon motion. In some cases, the centrifugal force will attract towards the axis of rotation. (author)

  14. Update on the nutrition situation.

    Mason, J; Garcia, M

    1995-01-01

    The Update on the Nutrition Situation, 1994 was published in early 1995 by the United Nations Subcommittee on Nutrition. Thus, data available at the country level about estimates of the nutritional situation now provide trends of prevalences of underweight children in 35 countries for the 1990s. In Sub-Saharan Africa recent deterioration has occurred as a result of the general worsening of nutrition in Africa. However, in the Near East, North Africa, and South America the generally improving trends of the 1980s seem to be continuing with the likelihood of reaching the prevalences of the developed countries by the year 2000. A surveillance system in Bangladesh indicates improvement from 1990 to 1993; however, India data for 1991/92 indicate deterioration in 3 states and no significant change in 4, possibly connected the economic slowdown in the early 1990s. In many countries of southeast Asia, China, Middle America and the Caribbean, South America, the Near East and North Africa the improvement of rates could result in halving the prevalences of underweight children. The gross domestic product (GDP) is an important indicator of nutritional performance. During 1985-92 in Sub-Saharan Africa GDP declined by 0.8% and consequently the nutritional situation also deteriorated. In other areas of the world the GDP growth rates improved after 1990 and the underweight trends in the early 1990s were generally similar to those of the late 1980s. The nutritional improvement outside Sub-Saharan Africa and possibly India continued in the early 1990s. Rapid economic growth was associated with improving nutrition in Thailand and Vietnam in the 1980s and also to a smaller extent for Indonesia and China. Faster than average improvement is plausible for Jamaica, Sri Lanka, and Zimbabwe. Deteriorating cases are Ethiopia, Madagascar, and Rwanda. Economic growth, health, education, and community-based nutrition programs all contribute to improving nutrition.

  17. Thoughts on the Postpartum Situation

    2018-06-01

    Full Text Available The event of childbirth carries with it a dominant narrative: that a pregnant woman happily gives birth to a baby. This appears to be quite a simple formulation—as if a natural fact, as if plain and common sense. Yet, the complexities masked by the mythological and whitewashed quality of this narrative, as I have already argued recently in The Pregnancy ≠ Childbearing Project: A Phenomenology of Miscarriage (Feb 2017, harms and even kills women. In this paper, I expand on the problem of what I term “dismemberment after birth” as it operates invisibly in the “postpartum situation.” The dominant narrative, combined with a pervasive cultural misogynoir— manifesting specifically as an antagonism toward black women and women of color—as medicalized and ableist establishment of care, renders women without resource if they cannot maintain the desires and embodiments required of a contented and successful maternity. The naturalized assumptions about the narrative move from the birth event to “having a baby” are disrupted here with hope of opening up an opportunity to validate and diversify the more non-linear narratives. As an afterthought to these disruptions, I offer an additional challenge to anti-natalist thinking in its limited insight into the postpartum situation.

    The layperson's qualification to provide early care in emergency situations and basic life support (BLS) is fundamental to save lives and prevent sequels. The objective was to identify the level of knowledge of lay people about approaching an emergency victim. Structured interviews in non-technical language were used with a 385-subject sample, average age 35.4 (+/- 14.55) years, with more than 50% having a high school or university education. Over 55% of these observed situations with loss of consciousness, but only 31% called for specialized help. 34% underwent a first-aid course, but only 13% feel prepared. The most often cited place of learning was the driving school (DS), 35.9%. Other training places were higher when compared to the DS (p = 0.048). Almost 17% do not know how to recognize the presence of vital signs. Almost 31% do not know the telephone number of the emergency service. Laypersons have incomplete or incorrect knowledge about care for unconscious victims.

  19. Cardiopulmonary Resuscitation: Unusual Techniques for Unusual Situations

    2018-01-01

    Full Text Available Background: The cardiopulmonary resuscitation (CPR in prone position has been dealt with in 2010 American Heart Association (AHA guidelines but have not been reviewed in 2015 guidelines. The guidelines for patients presenting with cardiac arrest under general anesthesia in lateral decubitus position and regarding resuscitation in confined spaces like airplanes are also not available in AHA guidelines. This article is an attempt to highlight the techniques adopted for resuscitation in these unusual situations. Aims: This study aims to find out the methodology and efficacy in nonconventional CPR approaches such as CPR in prone, CPR in lateral position, and CPR in confined spaces. Methods: We conducted a literature search using MeSH search strings such as CPR + Prone position, CPR + lateral Position, and CPR + confined spaces. Results: No randomized controlled trials are available. The literature search gives a handful of case reports, some simulation- and manikin-based studies but none can qualify for class I evidence. The successful outcome of CPR performed in prone position has shown compressions delivered on the thoracic spine with the same rate and force as they were delivered during supine position. A hard surface is required under the patient to provide uniform force and sternal counter pressure. Two rescuer technique for providing successful chest compression in lateral position has been documented in the few case reports published. Over the head CPR and straddle (STR, CPR has been utilized for CPR in confined spaces. Ventilation in operating rooms was taken care by an advanced airway in situ. Conclusion: A large number of studies of high quality are required to be conducted to determine the efficacy of CPR in such positions.

    2016-01-01

    Purpose: In mammography, the height of the image receptor is adjusted to the patient before compressing the breast. An inadequate height setting can result in an imbalance between the forces applied by the image receptor and the paddle, causing the clamped breast to be pushed up or down relative to the body during compression. This leads to unnecessary stretching of the skin and other tissues around the breast, which can make the imaging procedure more painful for the patient. The goal of this study was to implement a method to measure and minimize the force imbalance, and to assess its feasibility as an objective and reproducible method of setting the image receptor height. Methods: A trial was conducted consisting of 13 craniocaudal mammographic compressions on a silicone breast phantom, each with the image receptor positioned at a different height. The image receptor height was varied over a range of 12 cm. In each compression, the force exerted by the compression paddle was increased up to 140 N in steps of 10 N. In addition to the paddle force, the authors measured the force exerted by the image receptor and the reaction force exerted on the patient body by the ground. The trial was repeated 8 times, with the phantom remounted at a slightly different orientation and position between the trials. Results: For a given paddle force, the obtained results showed that there is always exactly one image receptor height that leads to a balance of the forces on the breast. For the breast phantom, deviating from this specific height increased the force imbalance by 9.4 ± 1.9 N/cm (6.7%) for 140 N paddle force, and by 7.1 ± 1.6 N/cm (17.8%) for 40 N paddle force. The results also show that in situations where the force exerted by the image receptor is not measured, the craniocaudal force imbalance can still be determined by positioning the patient on a weighing scale and observing the changes in displayed weight during the procedure. Conclusions: In mammographic breast

    2005-01-01

    Students from a young age have developed in their own minds differing concepts of things such as all creatures having a soul. Also children see the environment and interpret what they see according to their own understanding and explanation. In particular, with regards to physics, things like light, heat, motion, structure of matter and energy are understood at the level of a child s comprehension. Most often the child s understanding varies quite differently from the actual true meaning. As a result the child is reluctant to accept any other explanation. In such situations the necessary difficulties must be tackled with care and caution pertinent to the individual. Studies at K.S.U University related to force and motion of various departments in the Faculty of Science and Letters have been investigated. After evaluations of all the findings a number of suggestions have been made to change student views and ideas

    1978-01-01

    The energy situation of Mexico is analyzed, including a projection to year 2000. An energy trade balance for 1975 is presented, including the energy invested in the imported and exported manufactured goods. Although Mexico is an oil exporting country, it is found that there was a net import of 32 million barrels of oil equivalent. The projection shows that by developing all alternative sources, hydrocarbons will supply 73% of all the primary energy at the end of the century. A 20,000 MW(e) nucleoelectric program would depress hydrocarbons percentage to 63%. It is concluded that there has been a lack of a coherent energy policy which would permit to elaborate adequate energy development programs. Some criteria are recommended for an energy policy: a) the oil export program should be reviewed; b) The country should encourage the generation of its own technology; c) The energy demand growth-rate should be maintained high enough until an acceptable level of per-capita consumption is reached; d) The internal prices of energy should be reviewed to modify the consumption scheme and e) The primary energy sources should be diversified as possible; with special emphasis on nuclear energy which is the only one important alternative at short time.

    Understanding the Coriolis effect is essential for explaining the movement of air masses and ocean currents. The lesson we propose aims to familiarize students with the manifestation of the Coriolis effect. Students are guided to build, using the GeoGebra software, a simulation of the motion of a body, related to a rotating reference system. The mathematical expression of the Coriolis force is deduced, for particular cases, and the Foucault's pendulum is presented and explained. Students have the opportunity to deepen the subject, by developing materials related to topics such as: • Global Wind Pattern • Ocean Currents • Coriolis Effect in Long Range Shooting • Finding the latitude with a Foucault Pendulum

    2010-01-01

    Astronomers have compiled evidence that what we always thought of as the actual universe- all the planets, stars, galaxies and matter in space -represents a mere 4% of what's out there. The rest is dark: 23% is called dark matter, 73% dark energy. Scientists have ideas about what dark matter is, but hardly any understanding about dark energy. This has led to rethinking traditional physics and cosmology. Assuming the existence of dark matter and that the law of gravitation is universal, two teams of astrophysicists, from Lawrence Berkeley National Laboratory and the Australian National University, analysed the universe's growth and to their surprise both concluded that the universe expansion is not slowing but speeding up. If the dominant force of evolution isn't gravity what is it?

  11. Transversal light forces in semiconductors

    CERN Document Server

    Lindberg, M

    2003-01-01

    The transversal light force is a well established effect in atomic and molecular systems that are exposed to spatially inhomogeneous light fields. In this paper it is shown theoretically that in an excited semiconductor, containing an electron-hole plasma or excitons, a similar light force exists, if the semiconductor is exposed to an ultrashort spatially inhomogeneous light field. The analysis is based on the equations of motion for the Wigner distribution functions of charge carrier populations and interband polarizations. The results show that, while the light force on the electron-hole plasma or the excitons does exist, its effects on the kinetic behaviour of the electron-hole plasma or the excitons are different compared to the situation in an atomic or molecular system. A detailed analysis presented here traces this difference back to the principal differences between atoms and molecules on the one hand and electron-hole plasmas or excitons on the other hand.

  12. Understanding the Colombian security situation

    Energy Technology Data Exchange (ETDEWEB)

    Ossa, C.

    1997-05-05

    Colombia is notorious for its violence. Lack of security can be related to: irregular war, social decay and a weak state. High poverty levels lead to a lack of respect for the law. Thus, drug dealing and kidnapping have become prominent in Colombian society with little hope of redress. State weakness means that crime remains uncontrolled, and Maxist guerillas have been unopposed by state forces. This has given rise to vigilantism in the form of paramilitaries, who simply add to the lawlessness. So far the international coal industry has been selectively protected by government troops and policies but the general chaos in society is increasingly likely to penetrate even these heavily defended enclaves, as the fundamental problems in Colombian society are as present in the coal areas as in society at large. Presidential elections are in process. The new government will either have to tackle lawlessness throughout the country or the coal industry may have to withdraw as paramilitaries escalate violence in the coal districts. 1 tab.

  13. Learning situation models in a smart home.

    Brdiczka, Oliver; Crowley, James L; Reignier, Patrick

    2009-02-01

    This paper addresses the problem of learning situation models for providing context-aware services. Context for modeling human behavior in a smart environment is represented by a situation model describing environment, users, and their activities. A framework for acquiring and evolving different layers of a situation model in a smart environment is proposed. Different learning methods are presented as part of this framework: role detection per entity, unsupervised extraction of situations from multimodal data, supervised learning of situation representations, and evolution of a predefined situation model with feedback. The situation model serves as frame and support for the different methods, permitting to stay in an intuitive declarative framework. The proposed methods have been integrated into a whole system for smart home environment. The implementation is detailed, and two evaluations are conducted in the smart home environment. The obtained results validate the proposed approach.

  14. Collaborative Commercial Space Situational Awareness

    There is an increasing recognition by commercial and civil space operators of the need for space situational awareness (SSA) data to support ongoing conjunction analysis, maneuver planning, and radio frequency interference mitigation as part of daily operations. While some SSA data is available from the Joint Space Operations Center via the Space Track web site, access to raw observations and photometric data is limited due to national security considerations. These data, however, are of significant value in calibrating intra- and inter-operator orbit determination results, determining inter-system biases, and assessing operating profiles in the geostationary orbit. This paper details an ongoing collaborative effort to collect and process optical observations and photometric data using a network of low-cost telescope installations and shows how these data are being used to support ongoing operations in the Space Data Center. This presentation will demonstrate how by leveraging advance photometric processing algorithms developed for Missile Defense Agency and the Ballistic Missile Defense (BMD) mission ExoAnalytic and AGI have been able to provide actionable SSA for satellite operators from small telescopes in less than optimal viewing conditions. Space has become an increasingly cluttered environment requiring satellite operators to remain forever vigilant in order to prevent collisions to preserve their assets and prevent further cluttering the space environment. The Joint Space Operations Center (JSpOC), which tracks all objects in earth orbit, reports possible upcoming conjunctions to operators by providing Conjunction Summary Messages (CSMs). However due to large positional uncertainties in the forward predicted position of space objects at the time closest approach the volume of CSMs is excessive to the point that maneuvers in response to CSMs without additional screening is cost prohibitive. CSSI and the Space Data Association have been able to screen most

    CERN Document Server

    2013-01-01

    With so many terms available to define the same thing, it would seem nearly irresponsible to introduce yet another term (complex situation) to describe a phenomenological state of such as a system. However, a complex situation infers both a broader meaning and imposes a different perspective. Complex in this context is dependent on understanding and reality rather than observer and knowledge.   Situation imposes a gestalt that cannot be characterized within a singular perspective that relegates paradox to a superior/subordinate hierarchy. This also infers that complex situation has no monotonic definition or each definition is by default incomplete. Therefore the perennial derivations for systems such as complex systems, system of systems, federation of systems is no longer a sufficient descriptor for complex situation.  Ergo system and its genealogy lack the constitution to define complex situations. The books' intent is to explore this pathology through a series of papers written by authors that work in ...

    Science.gov (United States)

    Gockchinar, T; Kalipsi, S

    2001-01-01

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

    How to get the real-time value of forces dropped on the tool in the course of processing by piezoelectric sensors is introduced. First, the analog signals of the cutting force were achieved by these sensors, amplified and transferred into digital signals by A/D transferring card. Then real-time software reads the information, put it into its own coordinate, drew the curve of forces, displayed it on the screen by the real time and saved it for the technicians to analyze the situation of the tool. So the cutting parameter can be optimized to improve surface quality of the pieces.

    2009-06-01

    Full Text Available The personalization of learning is a major pedagogical challenge solicited by pedagogues and didacts. There are several projects about the production of personalizable learning situations such as Reload-LDE and Alfanet. These projects are interested in producing new standardized and personalizable learning situations. However, on the Web, an important number of learning situations exist. These situations are rich in information but don't consider all the characteristics of participants taking part in the learning, nor their technical environments. In this paper we suggest a help system that can transform an existing learning situation to another structure standardized and personalizable depending on the context of learning personalization that we have defined.

  1. Toward Microsatellite Based Space Situational Awareness

    Science.gov (United States)

    Scott, L.; Wallace, B.; Sale, M.; Thorsteinson, S.

    2013-09-01

    The NEOSSat microsatellite is a dual mission space telescope which will perform asteroid detection and Space Situational Awareness (SSA) observation experiments on deep space, earth orbiting objects. NEOSSat was launched on 25 February 2013 into a 800 dawn-dusk sun synchronous orbit and is currently undergoing satellite commissioning. The microsatellite consists of a small aperture optical telescope, GPS receiver, high performance attitude control system, and stray light rejection baffle designed to reject stray light from the Sun while searching for asteroids with elongations 45 degrees along the ecliptic. The SSA experimental mission, referred to as HEOSS (High Earth Orbit Space Surveillance), will focus on objects in deep space orbits. The HEOSS mission objective is to evaluate the utility of microsatellites to perform catalog maintenance observations of resident space objects in a manner consistent with the needs of the Canadian Forces. The advantages of placing a space surveillance sensor in low Earth orbit are that the observer can conduct observations without the day-night interruption cycle experienced by ground based telescopes, the telescope is insensitive to adverse weather and the system has visibility to deep space resident space objects which are not normally visible from ground based sensors. Also, from a photometric standpoint, the microsatellite is able to conduct observations on objects with a rapidly changing observer position. The possibility of spin axis estimation on geostationary satellites may be possible and an experiment characterize spin axis of distant resident space objects is being planned. Also, HEOSS offers the ability to conduct observations of satellites at high phase angles which can potentially extend the trackable portion of space in which deep space objects' orbits can be monitored. In this paper we describe the HEOSS SSA experimental data processing system and the preliminary findings of the catalog maintenance experiments

    Health Care professionals working in disaster situations have to face urgent choices which diverge from their normal deontological ethos and are more utilitarian. Such is the triage system used to choose whom to treat. Instead of entering a crisis these professionals should be thought that ethics is not harmonizable to all situations and that there are situations in which saving as many lives as possible mean sacrificing others. This calls for defining a perimeter zone in which such choices occur, and a time frame (a space-time niche) in which it ought to be considered ethical and legitimate to use such value laden choices.

    Full Text Available In order to reflect the situation of network security assessment performance fully and accurately, a new network security situation awareness model based on information fusion was proposed. Network security situation is the result of fusion three aspects evaluation. In terms of attack, to improve the accuracy of evaluation, a situation assessment method of DDoS attack based on the information of data packet was proposed. In terms of vulnerability, a improved Common Vulnerability Scoring System (CVSS was raised and maked the assessment more comprehensive. In terms of node weights, the method of calculating the combined weights and optimizing the result by Sequence Quadratic Program (SQP algorithm which reduced the uncertainty of fusion was raised. To verify the validity and necessity of the method, a testing platform was built and used to test through evaluating 2000 DAPRA data sets. Experiments show that the method can improve the accuracy of evaluation results.

    Does situational leadership style impact workers with disabilities? Situational leadership as a model and style of organizational management is defined. With a concentration on workers with disabilities, employer and employee perceptions of the workplace environment are analyzed as a contributing factor to the choice of leadership styles. Leadership style and its potential impact on workers with disabilities are included. Advantages of situational leadership style as an organizational model for managers that matches the intricate needs of workers with disabilities are argued. Methods for increasing awareness of the needs of persons with disabilities in the workplace and improving leadership models are discussed. Implications and potential outcomes for workers with disabilities based on the use of situational leadership by managers are discussed.

  13. Diagnostic orientation in control of disturbance situations

    International Nuclear Information System (INIS)

    Hukki, K.; Norros, L.

    1993-01-01

    The object of the study is diagnostic judgement in the control of dynamic processes. The starting point was the known difficulty process operators have in utilizing knowledge of process dynamics in disturbance situations that require both diagnostic and prognostic actions. A model of the diagnostic judgement process as a construction of coherent interpretation of the situation is outlined, and comprehensive data from simulated disturbance handling by 6 crews of a PWR type nuclear power plant was analysed. The phase of analysis included evaluation of the adequacy of task performance, utilization of available process information, and evaluation of the interpretation of disturbance situations. The results suggest that a functional orientation towards task performance allows a more coherent and comprehensive interpretation of the situation and more adequate task performance. Coherence of interpretation seems to be reflected in a higher subjective certainty compared with crews with an incoherent interpretation. (author). 15 refs, 2 figs, 2 tabs

    This report presents methods for continuous measures for Situation Awareness and Workload. The objective has been to identify, develop and test the new measures, and compare them to instruments that require interruptions of scenarios. The new measures are: (1) the Visual Indicator of Situation Awareness (VISA); where Situation Awareness is scored from predefined areas of visual interest critical for solving scenarios. Visual monitoring of areas was recorded by eye-movement tracking. (2) Workload scores reflected by Extended Dwell Time (EDT) and the operator Activity Level. EDT was calculated from eye-movement data files, and the activity level was estimated from simulator logs. Using experimental data from the 1996 CASH NRC Alarm study and the 1997 Human Error Analysis Project/ Human-Centred Automation study, the new measurement techniques have been tested and evaluated on a preliminary basis. The results showed promising relationships between the new continuous measures of situation awareness and workload, and established instruments based upon scenario interruptions. (author)

    2015-09-01

    Situated cognition seems incompatible with strong decoupling, where representations are deployed in the absence of their targets and are not oriented toward physical action. Yet, in art consumption, the epitome of a strongly decoupled cognitive process, the artwork is a physical part of the environment and partly controls the perception of its target by the audience, leading to immersion. Hence, art consumption combines strong decoupling with situated cognition.

    Full Text Available Clarinettists close and open multiple tone holes to alter the pitch of the tones. Their fingering technique must be fast, precise, and coordinated with the tongue articulation. In this empirical study, finger force profiles and tongue techniques of clarinet students (N = 17 and professional clarinettists (N = 6 were investigated under controlled performance conditions. First, in an expressive-performance task, eight selected excerpts from the first Weber Concerto were performed. These excerpts were chosen to fit in a 2 x 2 x 2 design (register: low--high; tempo: slow--fast, dynamics: soft--loud. There was an additional condition controlled by the experimenter, which determined the expression levels (low--high of the performers. Second, a technical-exercise task, an isochronous 23-tone melody was designed that required different effectors to produce the sequence (finger-only, tongue-only, combined tongue-finger actions. The melody was performed in three tempo conditions (slow, medium, fast in a synchronization-continuation paradigm. Participants played on a sensor-equipped Viennese clarinet, which tracked finger forces and reed oscillations simultaneously. From the data, average finger force (Fmean and peak force (Fmax were calculated. The overall finger forces were low (Fmean = 1.17 N, Fmax = 3.05 N compared to those on other musical instruments (e.g. guitar. Participants applied the largest finger forces during the high expression level performance conditions (Fmean = 1.21 N.For the technical exercise task, timing and articulation information were extracted from the reed signal. Here, the timing precision of the fingers deteriorated the timing precision of the tongue for combined tongue-finger actions, especially for faster tempi. Although individual finger force profiles were overlapping, the group of professional players applied less finger force overall (Fmean = 0.54 N. Such sensor instruments provide useful insights into player

    The High Performance Computing Software Applications Institute for Space Situational Awareness (HSAI-SSA) has completed its first full year of applications development. The emphasis of our work in this first year was in improving space surveillance sensor models and image enhancement software. These applications are the Space Surveillance Network Analysis Model (SSNAM), the Air Force Space Fence simulation (SimFence), and physically constrained iterative de-convolution (PCID) image enhancement software tool. Specifically, we have demonstrated order of magnitude speed-up in those codes running on the latest Cray XD-1 Linux supercomputer (Hoku) at the Maui High Performance Computing Center. The software applications improvements that HSAI-SSA has made, has had significant impact to the warfighter and has fundamentally changed the role of high performance computing in SSA.

    Quitzau, Maj-Britt; Petersen, Jens-Phillip

    This paper illustrates how strategic and situated forms of knowledge may increase capacity to implement energy strategies in local urban development projects. Through analysis of front runner implementation projects, we show that the involved planners utilize situational learning processes...... strategically to develop more viable implementation trajectories. These findings resonate well with relational and network orienteered research in contemporary planning theory. In the selected case studies, we can see that planners deliberately seek to extend traditional planning approaches, like e.......g. regulation, with broader context‐specific learning processes. In doing so, we argue that – what we call – an implementation synergy is established by interlacing different forms of situational knowledge with strategic knowledge about how to reach a desired energy target. In conclusion, the paper identifies...

While tools used for fault-tolerant control design based on physical principles and relations are valuable tools...... for designing robust systems, the models become too complex when considering the interactions on a plant-wide level. The alarm systems meant to support human operators in the diagnosis of the plant-wide situation on the other hand fail regularly in situations where these interactions of systems lead to many...... the interconnected systems can be inferred and alarm floods can potentially be reduced to their root-cause.

  15. Legal assessment of current situation on orphan patients in Lithuania.

    Science.gov (United States)

    Spokiene, Indre

    2008-01-01

    After Lithuania joined the European Union, the Regulation (EC) No. 141/2000 on orphan medicinal products and Commission Regulation (EC) No. 847/2000 came into force as part of national legislation. Member States must adopt specific measures to increase knowledge on rare diseases and to improve their detection, diagnosis, and treatment. The aim of this article was to present and to assess the current legal situation on orphan patients and their treatment in Lithuania, to identify legislation gaps, and to propose some ideas how to facilitate the solution of the existing problems in this field. For this purpose, European Union and Lithuanian legal documents on rare medicinal products are examined using a comparative method. With reference to inventory of Member States' incentives for rare diseases in national level, the most important issues, which orphan patients face to in Lithuania, are singled out. In Lithuania, the situation of orphan patients in terms of protection of patient rights is insufficiently determined. The access to effective health care services or approved therapies in some cases is restricted. Working relationships between genetic services and various clinical specialists as well as with those in primary care are not legally determined; the number of clinical trials aimed at orphan medicinal products is low. These results suggest a need for awareness raising among Lithuanian Government, health care specialists, patient organizations about the importance to improve practical implementation of European Union legislation and progressive experience of some European countries in this field.

  16. Forces in general relativity

    International Nuclear Information System (INIS)

    Ridgely, Charles T

    2010-01-01

    Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced by an observer in general coordinates. The general force is then applied to the local co-moving coordinate system of a uniformly accelerating observer, leading to an expression of the inertial force experienced by the observer. Next, applying the general force in Schwarzschild coordinates is shown to lead to familiar expressions of the gravitational force. As a more complex demonstration, the general force is applied to an observer in Boyer-Lindquist coordinates near a rotating, Kerr black hole. It is then shown that when the angular momentum of the black hole goes to zero, the force on the observer reduces to the force on an observer held stationary in Schwarzschild coordinates. As a final consideration, the force on an observer moving in rotating coordinates is derived. Expressing the force in terms of Christoffel symbols in rotating coordinates leads to familiar expressions of the centrifugal and Coriolis forces on the observer. It is envisioned that the techniques presented herein will be most useful to graduate level students, as well as those undergraduate students having experience with general relativity and tensor analysis.

    To develop a business and plan for the future, there is a need to assess the current situation. One way of doing this is to use Porter's five forces framework. This was the brainchild of Harvard Business School's Michael Porter and developed in 1979. Looking at the competitive intensity of an industry, the model assesses internal and external factors that act together to determine the direction of the business; taken together, this gives an indication of the attractiveness of the industry.

    This study compared pilot situation awareness across three traffic management concepts. The Concepts varied in terms of the allocation of traffic avoidance responsibility between the pilot on the flight deck, the air traffic controllers, and a conflict resolution automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to fully handle the responsibility of weather avoidance and maintaining separation between ownship and surrounding traffic. In Concept 2, pilots were not responsible for traffic separation, but were provided tools for weather and traffic avoidance. In Concept 3, flight deck tools allowed pilots to deviate for weather, but conflict detection tools were disabled. In this concept pilots were dependent on ground based automation for conflict detection and resolution. Situation awareness of the pilots was measured using online probes. Results showed that individual situation awareness was highest in Concept 1, where the pilots were most engaged, and lowest in Concept 3, where automation was heavily used. These findings suggest that for conflict resolution tasks, situation awareness is improved when pilots remain in the decision-making loop.

  2. Athletic Training Clinical Instructors as Situational Leaders.

    Science.gov (United States)

    Meyer, Linda Platt

    2002-12-01

    OBJECTIVE: To present Situational Leadership as a model that can be implemented by clinical instructors during clinical education. Effective leadership occurs when the leadership style is matched with the observed followers' characteristics. Effective leaders anticipate and assess change and adapt quickly and grow with the change, all while leading followers to do the same. As athletic training students' levels of readiness change, clinical instructors also need to transform their leadership styles and strategies to match the students' ever-changing observed needs in different situations. DATA SOURCES: CINAHL (1982-2002), MEDLINE (1990-2001), SPORT Discus (1949-2002), ERIC (1966-2002), and Internet Web sites were searched. Search terms included leadership, situational leadership, clinical instructors and leadership, teachers as leaders, and clinical education. DATA SYNTHESIS: Situational Leadership is presented as a leadership model to be used by clinical instructors while teaching and supervising athletic training students in the clinical setting. This model can be implemented to improve the clinical-education process. Situational leaders, eg, clinical instructors, must have the flexibility and range of skills to vary their leadership styles to match the challenges that occur while teaching athletic training students. CONCLUSIONS/RECOMMENDATIONS: This leadership style causes the leader to carry a substantial responsibility to lead while giving power away. Communication is one of the most important leadership skills to develop to become an effective leader. It is imperative for the future of the profession that certified athletic trainers continue to develop effective leadership skills to address the changing times in education and expectations of the athletic training profession.

  3. Malaysia and forced migration

    Directory of Open Access Journals (Sweden)

    Arzura Idris

    2012-06-01

    Full Text Available This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysia due to “south-south forced migration movements.” These responses are, however, inadequate in terms of commitment to the international refugee regime. While Malaysia did respond to economic and migration challenges, the paper asserts that such efforts are futile if she ignores issues critical to forced migrants.

  5. Three-nucleon forces

    International Nuclear Information System (INIS)

    Sauer, P.U.

    2014-01-01

    In this paper, the role of three-nucleon forces in ab initio calculations of nuclear systems is investigated. The difference between genuine and induced many-nucleon forces is emphasized. Induced forces arise in the process of solving the nuclear many-body problem as technical intermediaries toward calculationally converged results. Genuine forces make up the Hamiltonian. They represent the chosen underlying dynamics. The hierarchy of contributions arising from genuine two-, three- and many-nucleon forces is discussed. Signals for the need of the inclusion of genuine three-nucleon forces are studied in nuclear systems, technically best under control, especially in three-nucleon and four-nucleon systems. Genuine three-nucleon forces are important for details in the description of some observables. Their contributions to observables are small on the scale set by two-nucleon forces. (author)

  7. The force of dissimilar analogies in bioethics.

    Science.gov (United States)

    Mertes, Heidi; Pennings, Guido

    2011-04-01

    Although analogical reasoning has long been a popular method of reasoning in bioethics, current literature does not sufficiently grasp its variety. We assert that the main shortcoming is the fact that an analogy's value is often judged on the extent of similarity between the source situation and the target situation, while in (bio)ethics, analogies are often used because of certain dissimilarities rather than in spite of them. We make a clear distinction between dissimilarities that aim to reinforce a similar approach in the source situation and the target situation and dissimilarities that aim to undermine or denounce a similar approach. The former kind of dissimilarity offers the analogy more normative force than if there were no dissimilarities present; this is often overlooked by authors who regard all relevant dissimilarities as detrimental to the analogy's strength. Another observation is that an evaluation of the normative force of an analogy cannot be made independently of moral principles or theories. Without these, one cannot select which elements in an analogy are morally relevant nor determine how they should be interpreted.

    Dan'ko, S G; Boĭtsova, Iu A; Kachalova, L M

    2011-01-01

    Group 1 (N = 30) and group 2 (N = 22) of healthy volunteers participated in the experiment. EEG registration took place while the examinees were in the resting states: with closed eyes; with opened eyes; with opened eyes and being under exposure to TV channel noises (white noise). Group 1 had also to fulfill a task to count randomly appearing symbols on a screen and group 2 had to fulfill a task to find an image in the noises. Averaged values of EEG power in each of the derivations in each of the derivations were calculated for an every examinee and for each of the states. The estimations were done in delta, theta, alpha1, alpha2, beta1, beta2, gamma frequency bands. The received results demonstrate that exposure to unstructured non-informative video noise can lead to significant changes of EEG power in a variety of frequency bands which are most prominent in the band alpha2. The changes are topically widespread, reflecting systemic changes in corresponding brain mechanisms, but are much less intensive if compared to changes between resting states with opened and closed eyes.

    Science.gov (United States)

    Larcan, Alain; Julien, Henri

    2010-06-01

    First-aid--treatment aimed at enabling a victim to survive pending the arrival of qualified medical support--is less well developed in France than in many other industrialized countries, especially among the general public. The current status of first-aid in France is paradoxical: schooling is free and obligatory, the ambulance service and emergency services are of the highest quality, but the general public are too often passive and unknowledgeable when faced with an emergency situation. This situation is due to several factors, including the complexity of first-aid training and regulations, the involvement of too many public bodies, the legal liability of the first-aider, and a lack of ongoing training. The French National Academy of Medicine recommends 8 measures to improve this situation: Provide a legal definition of first-aid: "a set of recognized measures aimed, in an emergency setting, at preserving the physical and psychological integrity of the victim of an accident or illness, notably pending the arrival of professional medical assistance". Waive, as in many other countries, civil and legal responsibility for the non professional first-aider, except in case of clear negligence. Reinforce the organization of first-aid in France in order to monitor the number and quality of first-aiders, and to ensure theoretical and pedagogic research; create a communications department capable of supporting and promoting first-aid. Improve access to first-aid training by increasing the number of situations in which it is obligatory (driving tuition, school and university examinations, group responsibility, at-risk practices), by providing financial assistance for certain groups, and by ensuring routine training at school, in the armed forces, and in the workplace. Create a progressive and integrated citizen first-aid training course with individual modules, ensuring that first-aiders update and perfect their knowledge throughout life. Soften pedagogic rules and shorten

  18. Situated learning - beyond apprenticeship and social constructionism

    DEFF Research Database (Denmark)

    Christensen, Gerd

    2016-01-01

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

  19. The role of the situation in leadership.

    Science.gov (United States)

    Vroom, Victor H; Jago, Arthur G

    2007-01-01

    Leadership depends on the situation. Few social scientists would dispute the validity of this statement. But the statement can be interpreted in many different ways, depending, at least in part, on what one means by leadership. This article begins with a definition of leadership and a brief description of 3 historically important theories of leadership. The most recent of these, contingency theories, is argued to be most consistent with existing evidence and most relevant to professional practice. The Vroom, Yetton, and Jago contingency models of participation in decision making are described in depth, and their work provides the basis for identifying 3 distinct ways in which situational or contextual variables are relevant to both research on and the practice of leadership.

    Cyber defense competitions arising from U.S. service academy exercises, offer a platform for collecting data that can inform research that ranges from characterizing the ideal cyber warrior to describing behaviors during certain challenging cyber defense situations. This knowledge could lead to better preparation of cyber defenders in both military and civilian settings. This paper describes how one regional competition, the PRCCDC, a participant in the national CCDC program, conducted proof of concept experimentation to collect data during the annual competition for later analysis. The intent is to create an ongoing research agenda that expands on this current work and incorporates augmented cognition and gamification methods for measuring cybersecurity situational awareness under the stress of cyber attack.

    2007-01-01

    In the field of precautionary radiation protection and disaster response, the amount of information and the number of its sources is steadily increasing. Central compilation and instant availability of information for all involved authorities becomes more and more important. In this context the structured presentation of documents on a web server in terms of an ''Electronic Situation Display'' (ESD) has been established. In Germany, there are several Electronic Situation Display prototypes run by federal and state authorities for various purposes and using different technical approaches. The systems of the federal states focus on workflow management. They provide emergency log books and information on the implementation of countermeasures for disaster response authorities. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) tasked the Federal Office for Radiation Protection (BfS) to develop the Federal Electronic Situation Display (ELAN) that is mainly used as an information platform for decision making in case of nuclear emergencies. Documents containing radiological data or results from Decision Support Systems are almost automatically integrated into ELAN. Read and write permissions for users are managed by a concept of specific roles. The federal ESD and the systems of the federal states will be coordinated in order to achieve a better harmonisation. Interfaces for data exchange and data processing must be defined. Authorities of the federal states can use protected areas within the federal ESD where information is kept confidential for internal use before it is distributed to other states and federal authorities. In addition, key information of Electronic Situation Displays from the federal states can automatically be integrated into ELAN. Several task groups of the IAEA are working on the development and realization of a prototype for an information platform harmonising ESDs on international level. (orig.)

    The need for assessing internal radiation doses in emergency situations was demonstrated after accidents in Brazil, Ukraine and other countries. Lately more and more concern has been expressed regarding malevolent use of radiation and radioactive materials. The scenarios for such use are more difficult to predict than for nuclear power plant or weapons accidents. Much of the results of the work done in the IRADES project can be adopted for use in various accidental situations involving radionuclides that are not addressed in this report. If an emergency situation occurs in only one or a few of the Nordic countries, experts from the other countries could be called upon to assist in monitoring. A big advantage is then our common platform. In the Nordic countries much work has been put down on quality assurance of measurements and on training of dose assessment calculations. Attention to this was addressed at the internal dosimetry course in October 2005. Nordic emergency preparedness exercises have so far not included training of direct measurements of people in the early phase of an emergency. The aim of the IRADES project was to improve the preparedness especially for thyroid measurements. The modest financial support did not enable the participants to make big efforts but certainly acted as a much appreciated reminder of the importance of being prepared also to handle situations with malevolent use of radioactive materials. It was left to each country to decide to which extent to improve the practical skills. There is still a need for detailed national implementation plans. Measurement strategies need to be developed in each country separately taking into account national regulations, local circumstances and resources. End users of the IRADES report are the radiation protection authorities. (au)

Nordic emergency preparedness exercises have so far not included training of direct measurements of people in the early phase of an emergency. The aim of the IRADES project was to improve the preparedness especially for thyroid measurements. The modest financial support did not enable the participants to make big efforts but certainly acted as a much appreciated reminder of the importance of being prepared also to handle situations with malevolent use of radioactive materials. It was left to each country to decide to which extent to improve the practical skills. There is still a need for detailed national implementation plans. Measurement strategies need to be developed in each country separately taking into account national regulations, local circumstances and resources. End users of the IRADES report are the radiation protection authorities. (au)

    The main aim of this research was to investigate the decision making process in risky situations. We studied how different types of feedback on risky driving behaviors modulate risk evaluation and risk-taking. For a set of risky traffic situations, participants had to make evaluative judgments (judge the situation as risky or not) and urgent decisions (brake or not). In Experiment 1, participants received feedback with and without negative emotional content when they made risky behaviors. In Experiment 2 we investigated the independent effects of feedback and negative emotional stimuli. The results showed three important findings: First, urgent decisions were faster [F(1, 92) = 6.76, p = .01] and more cautious [F(1, 92) = 17.16, p towards more cautious responses [F(1, 111) = 14.09, p emotional stimuli had an effect only when they were presented as feedback. The results of this research increase our understanding of the processes involved in risky driving behavior and suggest efficient ways to control risk taking through the use of feedback.

    Describe the risk behaviour relationships with road safety in adolescents. Cross-sectional descriptive study. Madrid and Andalusia Regions, representative samples. The sample included 3,612 in secondary school pupils from Madrid (n=1708) and Andalusia (n=1904). The survey was carried out during May and June 2007. The data collected included sociodemographic areas (age, sex, grade, father's profession, birth place, etc.) and risk situation and behaviour (risk behaviour as driver or passenger). 16.2% of the adolescents have been involved in a dangerous situation with motorcycles during the last year. 16.7% never use a helmet when riding a motorcycle and 62% do not wear one when riding a bicycle on the road; 17.4% frequently ride a motorcycle over the speed limit and 24.5% when driving a car. There are significant differences regarding sex, grade and region (Madrid or Andalusia). There are four factors which explain 62% of the variance: drug factor, speed factor, security factor and passenger factor. Two of these have twice the probability of having a dangerous situation when riding a motorcycle: drug factor (OR=1.96; 95% CI, 1.77-2.18) and the speed factor ((OR=2.13; 95% CI, 1.92-2.36). Adolescents in higher grades and living in Andalusia were less road safety conscious. This pattern should be taken into account when designing preventive actions in Road Safety Education. 2009 Elsevier España, S.L. All rights reserved.

    To reduce the severity of injuries and the number of pedestrian deaths in traffic accidents, active safety devices providing pedestrian detection are considered effective countermeasures. The features of car-to-pedestrian collisions need to be known in detail to develop such safety devices. Because information on real-world accidents is limited, this study investigated near-miss situations captured by drive recorders installed in passenger cars. We showed similarities of the contact situation between near-miss incidents and real-world fatal pedestrian accidents in Japan. We analyzed the near-miss incident data via video capturing pedestrians crossing the road in front of forward-moving cars. Using a video frame captured by a drive recorder, the time to collision (TTC) was calculated from the car velocity and the distance between the car and pedestrian at the moment that the pedestrian initially appeared. The average TTC in the cases where pedestrians were not using a pedestrian crossing was shorter than that in the cases where pedestrians were using a pedestrian crossing. The average TTC in the cases where pedestrians emerged from behind obstructions was shorter than that in the cases where drivers had unobstructed views of the pedestrians. We propose that the specifications of the safety device for pedestrian detection and automatic braking should reflect the severe approach situation for a pedestrian and car including the TTC observed for near-miss incidents.

  8. Counterfactual Problem Solving and Situated Cognition

    Full Text Available The paper describes and interprets data of a study on counterfactual problem solving in representatives of modern industrial culture. The study was inspired by similar experiments carried out by A.R. Luria during his expedition to Central Asia. The hypothesis of our study was that representatives of modern industrial culture would solve counterfactual puzzles at a slower rate and with higher numbers of mistakes than similar non-counterfactual tasks. The experiments we conducted supported this hypothesis as well as provided us with some insights as to how to further develop it. For instance, we found no significant differences in time lag in solving counterfactual and ‘realistic’ tasks between the subjects with mathematical and the ones with liberal arts education. As an interpretation of the obtained data, we suggest a two-stage model of counterfactual problem solving: on the first stage, where situated cognition dominates, the realistic situation is transferred into the system of symbols unrelated to this very situation; on the second stage, operations are carried out within the framework of this new system of symbols.

    Recent advances in big data (BD) have focused research on the volume, velocity, veracity, and variety of data. These developments enable new opportunities in information management, visualization, machine learning, and information fusion that have potential implications for space situational awareness (SSA). In this paper, we explore some of these BD trends as applicable for SSA towards enhancing the space operating picture. The BD developments could increase in measures of performance and measures of effectiveness for future management of the space environment. The global SSA influences include resident space object (RSO) tracking and characterization, cyber protection, remote sensing, and information management. The local satellite awareness can benefit from space weather, health monitoring, and spectrum management for situation space understanding. One area in big data of importance to SSA is value - getting the correct data/information at the right time, which corresponds to SSA visualization for the operator. A SSA big data example is presented supporting disaster relief for space situation awareness, assessment, and understanding.

    Adolescence is a complex biopsychosocial phenomenon. All the inner-subjective changes in adolescents take place within the context of a specific social environment, which offers the necessary ideological setting that adolescents must confront in the course of their identity formation. Forced migration creates conditions under which the adolescent Ego may be traumatized more easily, resulting in the development of defensive mechanisms, which may interfere with the natural process of identity formation. The aim of this paper is to investigate how a traumatic situation such as forced migration may affect the mechanisms of identity formation in adolescence. For this purpose, clinical material, consisting of two cases of psychoanalytical psychotherapy of adolescents who were forced to immigrate to Greece, is presented and discussed in a psychoanalytical theoretical framework, along with the historical-sociological background.

    The Air Force has several unique requirements that are being met through the development of construction robotic technology. The missions associated with these requirements place construction/repair equipment operators in potentially harmful situations. Additionally, force reductions require that human resources be leveraged to the maximum extent possible and that more stringent construction repair requirements push for increased automation. To solve these problems, the U.S. Air Force is undertaking a research and development effort at Tyndall AFB, FL to develop robotic teleoperation, telerobotics, robotic vehicle communications, automated damage assessment, vehicle navigation, mission/vehicle task control architecture, and associated computing environment. The ultimate goal is the fielding of robotic repair capability operating at the level of supervised autonomy. The authors of this paper will discuss current and planned efforts in construction/repair, explosive ordnance disposal, hazardous waste cleanup, fire fighting, and space construction.

    The nucleon-deuteron analyzing power A y in elastic nucleon-deuteron scattering poses a longstanding puzzle. At energies E lab below approximately 30 MeV, A y cannot be described by any realistic NN force. The inclusion of existing three-nucleon forces does not improve the situation. Because of recent questions about the 3 P J NN phases, we examine whether reasonable changes in the NN force can resolve the puzzle. In order to do this, we investigate the effect on the 3 P J waves produced by changes in different parts of the potential (viz., the central force, tensor force, etc.), as well as on the 2-body observables and on A y . We find that it is not possible with reasonable changes in the NN potential to increase the 3-body A y , and at the same time to keep the 2-body observables unchanged. We therefore conclude that the A y puzzle is likely to be solved by new three-nucleon forces, such as those of spin-orbit type, which have not yet been taken into account. Refs. 7, tab. 1 (author)

    Research investigating the role of maladaptive emotion regulation on food intake has exclusively focused on food intake in a forced consumption situation. In contrast, the present study examined the effect of negative emotions (fear, negative affect) and emotion regulation strategies (suppression, reappraisal) on food intake in a non-forced, free eating setting where participants (N = 165) could choose whether and how much they ate. This free (ad libitum) eating approach enabled, for the firs...

    The capillary force in situations where the liquid meniscus is asymmetric, such as the one around a tilted object, has been hitherto barely investigated even though these situations are very common in practice. In particular, the capillary force exerted on a tilted object may depend on the dipping angle i. We investigate experimentally the capillary force that applies on a tilted cylinder as a function of its dipping angle i, using a home-built tilting Atomic Force Microscope (AFM) with custom made probes. A micrometric-size rod is glued at the end of an AFM cantilever of known stiffness, whose deflection is measured when the cylindrical probe is dipped in and retracted from reference liquids. We show that a torque correction is necessary to understand the measured deflection. We give the explicit expression of this correction as a function of the probes' geometrical parameters, so that its magnitude can be readily evaluated. The results are compatible with a vertical capillary force varying as 1/cosi, in agreement with a recent theoretical prediction. Finally, we discuss the accuracy of the method for measuring the surface tension times the cosine of the contact angle of the liquid on the probe. Copyright © 2017 Elsevier Inc. All rights reserved.

  18. Agent Based Modeling and Simulation of Pedestrian Crowds In Panic Situations

    KAUST Repository

    Alrashed, Mohammed

    2016-11-01

    The increasing occurrence of panic stampedes during mass events has motivated studying the impact of panic on crowd dynamics and the simulation of pedestrian flows in panic situations. The lack of understanding of panic stampedes still causes hundreds of fatalities each year, not to mention the scarce methodical studies of panic behavior capable of envisaging such crowd dynamics. Under those circumstances, there are thousands of fatalities and twice that many of injuries every year caused be crowd stampede worldwide, despite the tremendous efforts of crowd control and massive numbers of safekeeping forces. Pedestrian crowd dynamics are generally predictable in high-density crowds where pedestrians cannot move freely and thus gives rise to self-propelling interactions between pedestrians. Although every pedestrian has personal preferences, the motion dynamics can be modeled as a social force in such crowds. These forces are representations of internal preferences and objectives to perform certain actions or movements. The corresponding forces can be controlled for each individual to represent a different variety of behaviors that can be associated with panic situations such as escaping danger, clustering, and pushing. In this thesis, we use an agent-based model of pedestrian behavior in panic situations to predict the collective human behavior in such crowd dynamics. The proposed simulations suggests a practical way to alleviate fatalities and minimize the evacuation time in panic situations. Moreover, we introduce contagious panic and pushing behavior, resulting in a more realistic crowd dynamics model. The proposed methodology describes the intensity and spread of panic for each individual as a function of distances between pedestrians.

    In a two-dimensional world, a free quantum particle of vanishing angular momentum experiences an attractive force. This force originates from a modification of the classical centrifugal force due to the wave nature of the particle. For positive energies the quantum anticentrifugal force manifests itself in a bunching of the nodes of the energy wave functions towards the origin. For negative energies this force is sufficient to create a bound state in a two-dimensional δ-function potential. In a counterintuitive way, the attractive force pushes the particle away from the location of the δ-function potential. As a consequence, the particle is localized in a band-shaped domain around the origin

  2. Resource Management in Constrained Dynamic Situations

    Science.gov (United States)

    Seok, Jinwoo

    Resource management is considered in this dissertation for systems with limited resources, possibly combined with other system constraints, in unpredictably dynamic environments. Resources may represent fuel, power, capabilities, energy, and so on. Resource management is important for many practical systems; usually, resources are limited, and their use must be optimized. Furthermore, systems are often constrained, and constraints must be satisfied for safe operation. Simplistic resource management can result in poor use of resources and failure of the system. Furthermore, many real-world situations involve dynamic environments. Many traditional problems are formulated based on the assumptions of given probabilities or perfect knowledge of future events. However, in many cases, the future is completely unknown, and information on or probabilities about future events are not available. In other words, we operate in unpredictably dynamic situations. Thus, a method is needed to handle dynamic situations without knowledge of the future, but few formal methods have been developed to address them. Thus, the goal is to design resource management methods for constrained systems, with limited resources, in unpredictably dynamic environments. To this end, resource management is organized hierarchically into two levels: 1) planning, and 2) control. In the planning level, the set of tasks to be performed is scheduled based on limited resources to maximize resource usage in unpredictably dynamic environments. In the control level, the system controller is designed to follow the schedule by considering all the system constraints for safe and efficient operation. Consequently, this dissertation is mainly divided into two parts: 1) planning level design, based on finite state machines, and 2) control level methods, based on model predictive control. We define a recomposable restricted finite state machine to handle limited resource situations and unpredictably dynamic environments

    We consider two different forms for a relativistic version of a linear restoring force. The pair comes from taking Hooke's law to be the force appearing on the right-hand side of the relativistic expressions: d"p"/d"t" or d"p"/d["tau"]. Either formulation recovers Hooke's law in the non-relativistic limit. In addition to these two forces, we…

    Human learners can resolve referential ambiguity and discover the relationships between words and meanings through a cross-situational learning (CSL) strategy. Some people with aphasia (PWA) can learn word-referent pairings under referential uncertainty supported by online feedback. However, it remains unknown whether PWA can learn new words cross-situationally and if such learning ability is supported by statistical learning (SL) mechanisms. The present study examined whether PWA can learn novel word-referent mappings in a CSL task without feedback. We also studied whether CSL is related to SL in PWA and neurologically healthy individuals. We further examined whether aphasia severity, phonological processing and verbal short-term memory (STM) predict CSL in aphasia, and also whether individual differences in verbal STM modulate CSL in healthy older adults. Sixteen people with chronic aphasia underwent a CSL task that involved exposure to a series of individually ambiguous learning trials and a SL task that taps speech segmentation. Their learning ability was compared to 18 older controls and 39 young adults recruited for task validation. CSL in the aphasia group was below the older controls and young adults and took place at a slower rate. Importantly, we found a strong association between SL and CSL performance in all three groups. CSL was modulated by aphasia severity in the aphasia group, and by verbal STM capacity in the older controls. Our findings indicate that some PWA can preserve the ability to learn new word-referent associations cross-situationally. We suggest that both PWA and neurologically intact individuals may rely on SL mechanisms to achieve CSL and that verbal STM also influences CSL. These findings contribute to the ongoing debate on the cognitive mechanisms underlying this learning ability. Copyright © 2017 Elsevier Ltd. All rights reserved.

  5. Representing Operational Modes for Situation Awareness

    Operating complex plants is an increasingly demanding task for human operators. Diagnosis of and reaction to on-line events requires the interpretation of real time data. Vast amounts of sensor data as well as operational knowledge about the state and design of the plant are necessary to deduct reasonable reactions to abnormal situations. Intelligent computational support tools can make the operator’s task easier, but they require knowledge about the overall system in form of some model. While tools used for fault-tolerant control design based on physical principles and relations are valuable tools for designing robust systems, the models become too complex when considering the interactions on a plant-wide level. The alarm systems meant to support human operators in the diagnosis of the plant-wide situation on the other hand fail regularly in situations where these interactions of systems lead to many related alarms overloading the operator with alarm floods. Functional modelling can provide a middle way to reduce the complexity of plant-wide models by abstracting from physical details to more general functions and behaviours. Based on functional models the propagation of failures through the interconnected systems can be inferred and alarm floods can potentially be reduced to their root-cause. However, the desired behaviour of a complex system changes due to operating procedures that require more than one physical and functional configuration. In this paper a consistent representation of possible configurations is deduced from the analysis of an exemplary start-up procedure by functional models. The proposed interpretation of the modelling concepts simplifies the functional modelling of distinct modes. The analysis further reveals relevant links between the quantitative sensor data and the qualitative perspective of the diagnostics tool based on functional models. This will form the basis for the ongoing development of a novel real-time diagnostics system based

  6. Applying Cognitive Fusion to Space Situational Awareness

    Science.gov (United States)

    Ingram, S.; Shaw, M.; Chan, M.

    With recent increases in capability and frequency of rocket launches from countries across the world, maintaining a state-of-the-art Space Situational Awareness model is all the more necessary. We propose a fusion of real-time, natural language processing capability provided by IBM cognitive services with ground-based sensor data of positions and trajectories of satellites in all earth orbits. We believe such insight provided by cognitive services could help determine context to missile launches, help predict when a satellite of interest could be in danger, either by accident or by intent, and could alert interested parties to the perceived threat. We seek to implement an improved Space Situational Awareness model by developing a dynamic factor graph model informed by the fusion of ground-based ”structured” sensor data with ”unstructured” data from the public domain, such as news articles, blogs, and social media, in real time. To this end, we employ IBM’s Cognitive services, specifically, Watson Discovery. Watson Discovery allows real-time natural language processing of text including entity extraction, keyword search, taxonomy classification, concept tagging, relation extraction, sentiment analysis, and emotion analysis. We present various scenarios that demonstrate the utility of this new Space Situational Awareness model, each of which combine past structured information with related open source data. We demonstrate that should the model come to estimate a satellite is ”of interest”, it will indicate it as so, based on the most pertinent data, such as a reading from a sensor or by information available online. We present and discuss the most recent iterations of the model for satellites currently available on Space-Track.org.

  10. The power situation in Mid-Norway

    International Nuclear Information System (INIS)

    2006-01-01

    The strained power situation in Mid-Norway is in broad terms an energy problem, and the situation is especially precarious in the county of Moere og Romsdal. There is a risk that even in normal years, there will be insufficient energy supply unless new measures are implemented. There is a 50 percent chance that the situation will become more strained than in normal years. In the long term there is a possibility to increase the capacity of the system by increasing the import capacity as well as the production, but this is not realistic before 2011. A gas work at Tjeldbergodden can at the earliest be operative in 2011. The gas work at Skogn can at the earliest be operative in 2009, and needs to be accompanied by fortifications in the distribution net in order to help the situation in Moere og Romsdal. In short term the import capacity to the region will be reduced, and there are limits to how much new production capacity that can be taken in. Therefore, measures have to be made in order to reduce the consumption and increase the import. To make sure the measures will have satisfactory effect, they need to be implemented soon, so they can have effect over a longer period. It is limited how big reduction one can expect from the normal supply consumption. It is estimated that the consumption can be reduced by 10 percent at the maximum, by the use of high prices in the area, but this requires that the consumers expect a prolonged level of high energy prices at 0,80 Nok/kWh, and in addition short-term price fluctuations. Energy-intensive industry may find it profitable to reduce the consumption at prices below 0,80 Nok/kWh, but the potential for this is probably small in Moere og Romsdal. In a dry year it will hardly be possible to meet the energy demand without resorting to measures and in worst case rationing. The costs of rationing are substantially higher than the cost of backup power plants

    Fossil fuels provide the basis for world energy usage and, in the absence of fundamental policy changes, are expected to continue to do so for the next few decades. However, the prospect of global warming due to the greenhouse effect will have profound implications for the use of energy. This paper outlines the current situation and trends in world energy use, with a focus on energy requirements by region and fuel. Implications for greenhouse gas emissions and greenhouse policy challenges are also discussed. 8 refs., 1 tab., 2 figs

    1994-08-01

    This paper presents a theoretical and experimental investigation of a new kind of force sensor which detects forces by measuring an induced pressure change in a material of large Poisson's ratio. In this investigation we develop mathematical expressions for the sensor's sensitivity and bandwidth, and show that its sensitivity can be much larger and its bandwidth is usually smaller than those of existing strain-gage-type sensors. This force sensor is well-suited for measuring large but slowly varying forces. It can be installed in a space smaller than that required by existing sensors

  17. Force induced DNA melting

    When pulled along the axis, double-strand DNA undergoes a large conformational change and elongates by roughly twice its initial contour length at a pulling force of about 70 pN. The transition to this highly overstretched form of DNA is very cooperative. Applying a force perpendicular to the DNA axis (unzipping), double-strand DNA can also be separated into two single-stranded DNA, this being a fundamental process in DNA replication. We study the DNA overstretching and unzipping transition using fully atomistic molecular dynamics (MD) simulations and argue that the conformational changes of double-strand DNA associated with either of the above mentioned processes can be viewed as force induced DNA melting. As the force at one end of the DNA is increased the DNA starts melting abruptly/smoothly above a critical force depending on the pulling direction. The critical force f m , at which DNA melts completely decreases as the temperature of the system is increased. The melting force in the case of unzipping is smaller compared to the melting force when the DNA is pulled along the helical axis. In the case of melting through unzipping, the double-strand separation has jumps which correspond to the different energy minima arising due to sequence of different base pairs. The fraction of Watson-Crick base pair hydrogen bond breaking as a function of force does not show smooth and continuous behavior and consists of plateaus followed by sharp jumps.

    1988-01-01

    The Security Exercise Evaluation System (SEES) is under development for use in planning Force on Force exercises and as an aid in post-exercise evaluation. This study is part of the development cycle where the simulation results are compared to field data to provide guidance for further development of the model. SEES is an event-driven stochastic computer program simulating individual movement and combat within an urban terrain environment. The simulator models the physics of movement, line of sight, and weapon effects. It relies on the controllers to provide all knowledge of security tactics, which are entered by the controllers during the simulation using interactive color graphic workstations. They are able to develop, modify and implement plans promptly as the simulator maintains real time. This paper reports on how SEES will be used to develop an intrusion plan, test the security response tactics and develop observer logistics. A Force on Force field exercise will then be executed to follow the plan with observations recorded. An analysis is made by first comparing the plan and events of the simulation with the field exercise, modifying the simulation plan to match the actual field exercise, and then running the simulation to develop a distribution of possible outcomes

    The first biosimilar version of a biologic agent used to treat psoriasis (infliximab) entered the Spanish market on February 16 of this year, and more biosimilars can be expected to follow in the coming months and years. Logically, this new situation will have economic repercussions and alter prescribing patterns among dermatologists. In this article, we review regulatory issues related to the approval of biosimilars, with a particular focus on the situation in the European Union. We will examine analytical characterization studies and special considerations for clinical trials with biosimilars, and also look at several somewhat contentious issues, such as the extrapolation of indications, interchangeability, and automatic substitution. Finally, we will review the biosimilars with indications for psoriasis currently in the clinical development pipeline and assess their potential to offer comparable efficacy and safety to the reference product while contributing to the sustainability of the public health care system.

    In 1953, President Eisenhower announced the U.S. ''Atoms for Peace'' program. After slightly more than 30 years, there are in operation, under construction or on order more than 400,000 MW of commercial nuclear power generation capacity located in 35 nations, representing a total investment around a trillion U.S. dollars. The situation is noteworthy in terms of the rate of technical development, deployment and transfer, the magnitude of the financial investment, economic benefits, the favorable impact on public health and safety, and the usual and positive character of cooperation among all concerned. The fundamentals of nuclear power generation with regard to economics, safety and environmental impact are likely to favor the increased use of nuclear power. The future prospect of the nuclear power in the U.S. also will be clarified positively. In many ways, U.S. commercial nuclear power continues to benefit from the Navy nuclear propulsion program. The prospect of supply demand situation in the conversion, enrichment and fabrication of uranium fuel is explained. The amount of spent fuel arising in OECD countries and their storage capability up to 2000 are shown, and the storage capability projected is well in excess. (Kako, I.)

    Risk management has received increasing attention recently as methods of quantifying risk have been evolving. This is considered a legitimate tendency in the context of the entirety of risk evaluation which connotes both risk quantification and decisions making thereon. A risk-free society does not appear possible; neither could one have zero competing risks or cost versus benefit resulting out of a risk-abatement effort. What further complicates the risk-decision problem is that there exists more than a single decision maker, who claim their own interests associated with risk decision. Furthermore, their risk perceptions are not at all same that the threshold risk levels for a particular actions are varying. In this dissertation, a brief survey on existing action levels for various sort of risk situations including carcinogens, toxic chemicals, etc., is reported on, with emphasis on nuclear risk situation. A decision theoretic approach is then adopted in both individual and group-level risk management. For the purpose of exemplification, multiplicative utility theory is applied for nuclear power risk; attributes derived for this specific purpose are discussed

    An assessment of the Radiation Protection of Emergency Exposure Situations in Ghana was carried out in relation to documents provided by the International Atomic Energy Agency (IAEA). As realized in the document of the “Method for Developing Arrangements for Response to a Nuclear or Radiological Emergency” of the IAEA, the National Nuclear and Radiological Emergency Response Plan (NNRERP) of Ghana also discusses the Infrastructural and Functional Requirements necessary for the intervention of a nuclear or radiological emergency. The NNRERP describes the concept of operations for a response designed to facilitate the delivery of coordinated assistance to government authorities such as the National Disaster Management Organisation (NADMO), the Radiation Protection Board (RPB) and other participating organizations. From the NNRERP, practices in Ghana, fall into emergency planning category III and IV. As part of the planning measures, one of Ghana Atomic Energy Commission’s primary functions is to provide technical support with a mechanism for timely, interagency coordination of advice and recommendations to NADMO concerning protective actions, environmental concerns, health matters and other related matters. It has been realized from this assessment that there is an urgent need to upgrade infrastructure with logistics for training, exercises and drills to achieve its optimum expectations which will eventually lead to high level of confidence in meeting the standard of a Radiation Protection Programme in Emergency Exposure Situations.

    System concepts for network enabled image-based ISR (intelligence, surveillance, reconnaissance) is the major mission of Fraunhofer IITB's applied research in the area of defence and security solutions. For the TechDemo08 as part of the NATO CNAD POW Defence against terrorism Fraunhofer IITB advanced a new multi display concept to handle the shear amount and high complexity of ISR data acquired by networked, distributed surveillance systems with the objective to support the generation of a common situation picture. Amount and Complexity of ISR data demands an innovative man-machine interface concept for humans to deal with it. The IITB's concept is the Digital Map & Situation Surface. This concept offers to the user a coherent multi display environment combining a horizontal surface for the situation overview from the bird's eye view, an attached vertical display for collateral information and so-called foveatablets as personalized magic lenses in order to obtain high resolved and role-specific information about a focused areaof- interest and to interact with it. In the context of TechDemo08 the Digital Map & Situation Surface served as workspace for team-based situation visualization and analysis. Multiple sea- and landside surveillance components were connected to the system.

    Lundin, R.; Guglielmi, A.

    2006-12-01

    This review is devoted to ponderomotive forces and their importance for the acceleration of charged particles by electromagnetic waves in space plasmas. Ponderomotive forces constitute time-averaged nonlinear forces acting on a media in the presence of oscillating electromagnetic fields. Ponderomotive forces represent a useful analytical tool to describe plasma acceleration. Oscillating electromagnetic fields are also related with dissipative processes, such as heating of particles. Dissipative processes are, however, left outside these discussions. The focus will be entirely on the (conservative) ponderomotive forces acting in space plasmas. The review consists of seven sections. In Section 1, we explain the rational for using the auxiliary ponderomotive forces instead of the fundamental Lorentz force for the study of particle motions in oscillating fields. In Section 2, we present the Abraham, Miller, Lundin-Hultqvist and Barlow ponderomotive forces, and the Bolotovsky-Serov ponderomotive drift. The hydrodynamic, quasi-hydrodynamic, and ‘`test-particle’' approaches are used for the study of ponderomotive wave-particle interaction. The problems of self-consistency and regularization are discussed in Section 3. The model of static balance of forces (Section 4) exemplifies the interplay between thermal, gravitational and ponderomotive forces, but it also introduces a set of useful definitions, dimensionless parameters, etc. We analyze the Alfvén and ion cyclotron waves in static limit with emphasis on the specific distinction between traveling and standing waves. Particular attention has been given to the impact of traveling Alfvén waves on the steady state anabatic wind that blows over the polar regions (Section~5). We demonstrate the existence of a wave-induced cold anabatic wind. We also show that, at a critical point, the ponderomotive acceleration of the wind is a factor of 3 greater than the thermal acceleration. Section 6 demonstrates various

    Streptococcus suis, a major porcine pathogen and an important zoonotic agent, is considered to be composed of phenotypically and genetically diverse strains. However, recent studies reported several "S. suis-like strains" that were identified as S. suis by commonly used methods for the identification of this bacterium, but were regarded as distinct species from S. suis according to the standards of several taxonomic analyses. Furthermore, it has been suggested that some S. suis-like strains can be assigned to several novel species. In this review, we discuss the current taxonomical situation of S. suis with a focus on (1) the classification history of the taxon of S. suis; (2) S. suis-like strains revealed by taxonomic analyses; (3) methods for detecting and identifying this species, including a novel method that can distinguish S. suis isolates from S. suis-like strains; and (4) current topics on the reclassification of S. suis-like strains.

    This project explored the possibility of predicting pilot situational awareness (SA) using human performance modeling techniques for the purpose of evaluating developing cockpit systems. The Improved Performance Research Integration Tool (IMPRINT) was combined with the Adaptive Control of Thought-Rational (ACT-R) cognitive modeling architecture to produce a tool that can model both the discrete tasks of pilots and the cognitive processes associated with SA. The techniques for using this tool to predict SA were demonstrated using the newly developed Aviation Weather Information (AWIN) system. By providing an SA prediction tool to cockpit system designers, cockpit concepts can be assessed early in the design process while providing a cost-effective complement to the traditional pilot-in-the-loop experiments and data collection techniques.

However, we did not give sufficient attention to radiation protection involving, e.g. technology, legislation, until 1980s. Recently with the strong support from International Atomic Energy Agency (IAEA) and Vietnam government nuclear technology has been strongly and widely developed in different branches and radiation protection situation in Vietnam has been improved step by step. Strategy for Peaceful Utilization of Atomic Energy up to 2020 approved by the prime minister on January 3th, 2006 confirms that nuclear power plant will be put in operation by 2020. To ensure the implementation of the strategy, the first priority should be given to radiation protection and nuclear safety. This paper presents shortly some activities of radiation safety in Vietnam. The requirements for developing this field in Vietnam are also discussed. (author)

    Existing emergency procedures, whose purpose is residual heat removal and a safe recovery are based on sequential analysis and initiating event diagnosis. This approach was found in some cases inappropriate and inefficient, specially in case of out-of-design accidents corresponding to multiple equipment failure or simultaneous human failures. To cope with these situations, a new approach was necessary. Parallel studies performed in France at Framatome (the designer) and Electricity de France (the utility) gave a new method, called NSSS physical states approach. Prior to the implementation of this method which necessitates further studies and developments, some improvements in the existing operating procedures derived from the NSSS physical states have already been achieved: that is the case for the safety injection control and the development of an emergency procedure called ''U1''. This paper will briefly physical states approach and present the ''U1'' procedure. The tools which will be used to chack these methods are also mentioned

    2013-08-01

    The aim of the present mixed-method study was to investigate task-based situational interest of sixth grade students (n = 46), between 12 and 14 years old, during an eight-week engineering design programme in a Science & Technology-class. Students' interests were investigated by means of a descriptive interpretative analysis of qualitative data from classroom observations and informal interviews. The analysis was complemented by a self-report survey to validate findings and determine prevalence. The analysis revealed four main sources of interest: designing inventions, trial-and-error experimentation, achieved functionality of invention, and collaboration. These sources differ in terms of stimuli factors, such as novelty, autonomy (choice), social involvement, self-generation of interest, and task goal orientation. The study shows that design tasks stimulated interest, but only to the extent that students were able to self-regulate their learning strategies.

    2017-01-01

    In a large enterprise it is difficult for cyber security analysts to know what services and roles every machine on the network is performing (e.g., file server, domain name server, email server). Using network flow data, already collected by most enterprises, we developed a proof-of-concept tool that discovers the roles of a system using both clustering and categorization techniques. The tool's role information would allow cyber analysts to detect consequential changes in the network, initiate incident response plans, and optimize their security posture. The results of this proof-of-concept tool proved to be quite accurate on three real data sets. We will present the algorithms used in the tool, describe the results of preliminary testing, provide visualizations of the results, and discuss areas for future work. Without this kind of situational awareness, cyber analysts cannot quickly diagnose an attack or prioritize remedial actions.

    A geoeconomical analysis of lithium is carried out, from its natural occurrence to its final application as a commercial product. General geological aspects such as the most important lithium mines, their minerals and their world distribution are taken into account. Also discussed is the viewpoint of enterprises regarding the various economical sectors associated with the production, consumption, marketing, installed industrial capacity, preparation of new products, development programs and installation of new plants. The applications of lithium, its several alloys and other chemical compounds are considered. Conclusions from these studies and from the data acquired are drawn, regarding the present Brazilian situation and its perspectives towards a future demand for lithium. (C.L.B.) [pt

    2010-04-01

    This paper presents the operational solution developed by GMV to provide support to maritime situational awareness via Earth Observation (EO) technologies. The concept falls on integrating the information retrieved from Synthetic Aperture Radar (SAR) images and transponder-based polls (AIS and similar) in an advanced GeoPortal web. The service has been designed in the framework of the MARISS project, a project conceived to help improving ship monitoring with the support of a large user segment. In this context, the interaction with official agencies has provided good feedback about system performance and its usefulness in supporting monitoring and surveillance tasks. Some representative samples are analyzed along the paper in order to validate key kernel utilities, such as ship and coastline detection, and ship classification. They justify the promotion of extended R&D activities to increase monitoring performance and to include advanced added- value tools, such as decision making and route tracking.

    2018-04-25

    Cyberzone is a fitting place to start any discussion around Black lesbian identity in comics, as it is the first comic book that this researcher could find which features a Black lesbian female lead superheroine. Cyberzone was self-published by Jimmie Robinson in 1994 and later re-vamped into a mini-comic series called Amanda and Gunn with Image Comics. First, this article deconstructs Cyberzone through the lens of Cultural Prism Theory (CPT). Second, this article situates Cyberzone within the framework of CPT to address Cyberzone's place within the comic book ecosystem. Finally, this essay offers a close reading of Cyberzone, issues #1-#4, against the backdrop of the intersectional framework Black Queer Identity Matrix. During this process, the researcher demonstrates how Cyberzone is a powerful site of resistant cultural commentary.

    This study aimed to identify the correspondence of opinions between nurses and nursing staff members who work at the emergency unit regarding the leadership style performed by nurses and the style nurses must adopt considering the maturity level of nursing staff members and the care provided at the unit. Situational Leadership was adopted as a theoretical reference framework. In order to achieve these goals, instruments were elaborated and applied to 24 research participants. Results demonstrated that the leadership style nurses most frequently perform was E3 (participating), and that nurses should adopt leadership style E4 (delegating) in view of the nursing staff's level of maturity, suggesting that staff members present a high level of maturity (M4).

    To make appropriate, timely decisions in the field, Situational Awareness (SA) needs to be conveyed in a decentralized manner to the users at the edge of the network as well as at operations centers. Sharing real-time SA efficiently between command centers and operational troops poses many challenges, including handling heterogeneous and dynamic networks, resource constraints, and varying needs for the collection, dissemination, and display of information, as well as recording that information. A mapping application that allows teams to share relevant geospatial information efficiently and to communicate effectively with one another and command centers has wide applicability to many vertical markets across the Department of Defense, as well as a wide variety of federal, state local, and non-profit agencies that need to share locations, text, photos, and video. This paper describes the Android Team Awareness Kit (ATAK), an advanced, distributed tool for commercial- off-the-shelf (COTS) mobile devices such as smartphones and tablets. ATAK provides a variety of useful SA functions for soldiers, law enforcement, homeland defense, and civilian collaborative use; including mapping and navigation, range and bearing, text chat, force tracking, geospatial markup tools, image and file sharing, video playback, site surveys, and many others. This paper describes ATAK, the SA tools that ATAK has built-in, and the ways it is being used by a variety of military, homeland security, and law enforcement users.

  1. Beyond Insurgency to Radical Social Change: The New Situation

    Directory of Open Access Journals (Sweden)

    John Foran

    2014-04-01

    Full Text Available The Arab Spring and U.S. Occupy movements surprised the world in 2011, showing that movements for radical social change remain viable responses to the intertwined crises of globalization: economic precarity, political disenchantment, rampant inequality, and the long-term fuse of potentially catastrophic climate change. These movements possess political cultural affinities of emotion, historical memory, and oppositional and creative discourses with each other and with a chain of movements that have gathered renewed momentum and relevance as neoliberal globalization runs up against the consequences of its own rapaciousness.Three paths to radical social change have emerged that differ from the hierarchical revolutionary movements of the twentieth century: 1 the electoral path to power pursued by the Latin American Pink Tide nations, 2 the route of re-making power at the local level or seeking change at the global level, both by-passing the traditional goal of taking state power, and 3 the occupation of public space to force out tyrants, as in Tunisia and Egypt.This paper assesses the strengths and limitations of each path, arguing that social movements and progressive parties together may possess the best chances for making radical social change in this new situation. These threads of resistance may also point toward a future of radical social change as we imagine their enduring results, self-evident and more subtle. 

  2. Prediction of situational awareness in F-15 pilots.

    Carretta, T R; Perry, D C; Ree, M J

    1996-01-01

    Situational awareness (SA) is a skill often deemed essential to pilot performance in both combat and noncombat flying. A study was conducted to determine if SA in U.S. Air Force F-15 pilots could be predicted. The participants were 171 active duty F-15 A/C pilots who completed a test battery representative of various psychological constructs proposed or demonstrated to be valid for the prediction of performance in a wide variety of military and civilian jobs. These predictors encompassed measures of cognitive ability, psychomotor ability, and personality. Supervisor and peer ratings of SA were collected. Supervisors and peers showed substantial agreement on the SA ratings of the pilots. The first unrotated principle component extracted from the supervisor and peer ratings accounted for 92.5% of the variability of ratings. The unrotated first principal component served as the SA criterion. Flying experience measured in number of F-15 hours was the best predictor of SA. After controlling for the effects of F-15 flying hours, the measures of general cognitive ability based on working memory, spatial reasoning, and divided attention were found to be predictive of SA. Psychomotor and personality measures were not predictive. With additional F-15 flying hours it is expected that pilots would improve their ratings of SA.

    There have been numerous efforts to create comprehensive databases from multiple sources to monitor the dynamics of public health and most specifically to detect the potential threats of bioterrorism before widespread dissemination. But there are not many evidences for the assertion that these systems are timely and dependable, or can reliably identify man made from natural incident. One must evaluate the value of so called 'syndromic surveillance systems' along with the costs involved in design, development, implementation and maintenance of such systems and the costs involved in investigation of the inevitable false alarms1. In this article we will introduce a new perspective to the problem domain with a shift in paradigm from 'surveillance' toward 'awareness'. As we conceptualize a rather different approach to tackle the problem, we will introduce a different methodology in application of information science, computer science, cognitive science and human-computer interaction concepts in design and development of so called 'public health situation awareness systems'. We will share some of our design and implementation concepts for the prototype system that is under development in the Center for Biosecurity and Public Health Informatics Research, in the University of Texas Health Science Center at Houston. The system is based on a knowledgebase containing ontologies with different layers of abstraction, from multiple domains, that provide the context for information integration, knowledge discovery, interactive data mining, information visualization, information sharing and communications. The modular design of the knowledgebase and its knowledge representation formalism enables incremental evolution of the system from a partial system to a comprehensive knowledgebase of 'public health situation awareness' as it acquires new knowledge through interactions with domain experts or automatic discovery of new knowledge.

  4. Radiation protection programme for existing exposure situation

    2016-04-01

    This study was conducted to develop the Radiation protection Programme (RPP) to ensure that measures are in place for protection of individuals from the existing source of exposure. The study established a number of protective and remedial actions to be considered by the responsible regulatory Authority, licensee for existing exposure in workplace and dwellings. Tanzania is endowed with a number NORMs processing industries with an experience of uncontrolled exploration and extraction of minerals and the use of unsafe mining methods leading to severe environmental damage and appalling living conditions in the mining communities. Some of NORMs industries have been abandoned due to lack of an effect management infrastructure. The residual radioactive materials have been found to be the most import source of existing exposure resulted from NORMs industries. The Radon gas and its progeny have also been found to be a source of existing exposure from natural source as well as the major source of risk and health effects associated with existing exposure situation. The following measures have been discovered to play a pivotal role in avoiding or reducing the source of exposure to individuals such as restriction of the use of the construction materials, restriction on the consumption of foodstuffs and restriction on the access to the land and buildings, the removal of the magnitude of the source in terms of activity concentration as well as improvement of ventilation in dwellings. Therefore, the regulatory body (Tanzania Atomic Energy Commission) should examine the major areas outlined in the established RRP for existing exposure situation resulted from the NORMs industries and natural sources so as to develop strategies that will ensure the adequate protection of members of the public and the environment as well as guiding operating organizations to develop radiation protection and safety measures for workers.

  5. Hypothetical conflict situations with friends and peers

    2012-01-01

    Full Text Available This paper deals with age and sex differences in preferred strategies of conflict resolution in friendship and peer relationships. The study was conducted on the sample of 286 adolescents. Conflict resolution strategies have been investigated by the method of hypothetical conflict situations. For the purposes of this research, we have created an instrument consisting of 20 hypothetical situations, with the following subjects of conflict: breaking the agreement, non-compliance with opinion differences, provocations, dishonesty and stubbornness. Conflict resolution strategies we examined were giving in, withdrawal, competition and problem solving. The results have shown that problem solving is the dominant strategy of adolescents in conflict with friends, while in peer conflicts they more often opt for competition. Age differences are reflected in the fact that older adolescents are more likely to choose problem solving than younger, whereas younger adolescents are more likely to choose a retreat (withdrawal strategy than older. Girls are more prone to choosing problem solving than boys, who, on the other hand, tend to withdraw more than girls. Also, gender of the other person in the conflict is proved to be important - in conflict with male peers, adolescents choose competition to a greater extent and withdraw to a minor extent, compared to when they are in conflict with female peers. The results have practical implications as well. In programs for teaching constructive conflict resolution that are designed for younger adolescents there should be more emphasis on empowerment and training for assertive behaviour. In addition, when teaching about constructive conflict resolution strategies, it is important to consider the gender of adolescents as well as the gender of the person with whom they are in conflict.

  6. Register as the Situational Variety of Language

    Directory of Open Access Journals (Sweden)

    Natalya B. Boyeva-Omelechko

    2016-12-01

    Full Text Available The problem discussed in the article is topical due to the interest of scientists to different types of language variations and especially registers or situational dialects treated by M.A.K. Halliday as use-related varieties of language or varieties used in a particular social setting. As discourse categorization is a very complex problem scholarly consensus has not been reached for the definitions of the term «register». The universal criteria for defining and discriminating registers have not been worked out either. The authors of the article give the review of scientific works devoted to the problem in question especially works by M.A.K. Halliday, R. Quirk, M. Joos, D. Hymes P. Trudgill, E.I. Belyaeva and others and analyze different definitions of the term «register», spectrums of registers and criteria for their discriminating. It enables the authors to come to the conclusion that only registers with the same field (religious, political, business etc. and mode (oral/written, dialogue/monologue can be compared. The difference lies in the sphere of tenor which depends on the degree of formality, distance of power and socio-psychological distance between speakers. The authors believe that it is also necessary to take into account the cooperative/ uncooperative character of conversation and para-verbal and non-verbal components of the speech situation. With this in mind they offer their definition of the register and describe main characteristics of registers in the sphere of oral communication.

    Directory of Open Access Journals (Sweden)

    Alan Blum

    2013-12-01

    Full Text Available A review of the original paper on motive by Blum and McHugh (1971 is used as an occasion to make transparent an approach to social theory as it has developed over the years in their work. This method, in treating motive as an illustration, engages it as an example of the status of the signifier as a symptom of interpretive conflict endemic to any situation of action, always inviting an analysis of the symbolic order and imaginative structure that sustains the distinction as a force in social life. In this paper, motive in particular is unpacked to show how it serves as an indication of fundamental ambiguity with respect to a problem-solving situation, revealing in this case constant perplexity in relation to the enigmatic character of what comes to view on any occasion and the recurrent contestation that is released.

  11. Information-based physics, influence, and forces

    International Nuclear Information System (INIS)

    Walsh, James Lyons; Knuth, Kevin H.

    2015-01-01

    In recent works, Knuth and Bahreyni have demonstrated that the concepts of space and time are emergent in a coarse-grained model of direct particle-particle influence. In addition, Knuth demonstrated that observer-made inferences regarding the free particle, which is defined as a particle that influences others, but is not itself influenced, result in a situation identical to the Feynman checkerboard model of the Dirac equation. This suggests that the same theoretical framework that gives rise to an emergent spacetime is consistent with quantum mechanics. In this paper, we begin to explore the effect of influence on the emergent properties of a particle. This initial study suggests that when a particle is influenced, it is interpreted as accelerating in a manner consistent with special relativity implying that, at least in this situation, influence can be conceived of as a force

  12. OOTW Force Design Tools

    Energy Technology Data Exchange (ETDEWEB)

    Bell, R.E.; Hartley, D.S.III; Packard, S.L.

    1999-05-01

    This report documents refined requirements for tools to aid the process of force design in Operations Other Than War (OOTWs). It recommends actions for the creation of one tool and work on other tools relating to mission planning. It also identifies the governmental agencies and commands with interests in each tool, from whom should come the user advisory groups overseeing the respective tool development activities. The understanding of OOTWs and their analytical support requirements has matured to the point where action can be taken in three areas: force design, collaborative analysis, and impact analysis. While the nature of the action and the length of time before complete results can be expected depends on the area, in each case the action should begin immediately. Force design for OOTWs is not a technically difficult process. Like force design for combat operations, it is a process of matching the capabilities of forces against the specified and implied tasks of the operation, considering the constraints of logistics, transport and force availabilities. However, there is a critical difference that restricts the usefulness of combat force design tools for OOTWs: the combat tools are built to infer non-combat capability requirements from combat capability requirements and cannot reverse the direction of the inference, as is required for OOTWs. Recently, OOTWs have played a larger role in force assessment, system effectiveness and tradeoff analysis, and concept and doctrine development and analysis. In the first Quadrennial Defense Review (QDR), each of the Services created its own OOTW force design tool. Unfortunately, the tools address different parts of the problem and do not coordinate the use of competing capabilities. These tools satisfied the immediate requirements of the QDR, but do not provide a long-term cost-effective solution.

  13. Heisenberg equation for a nonrelativistic particle on a hypersurface: From the centripetal force to a curvature induced force

    Directory of Open Access Journals (Sweden)

    D. K. Lian

    2017-12-01

    Full Text Available In classical mechanics, a nonrelativistic particle constrained on an N − 1 curved hypersurface embedded in N flat space experiences the centripetal force only. In quantum mechanics, the situation is totally different for the presence of the geometric potential. We demonstrate that the motion of the quantum particle is ”driven” by not only the centripetal force, but also a curvature induced force proportional to the Laplacian of the mean curvature, which is fundamental in the interface physics, causing curvature driven interface evolution.

    This is a tutorial-style selective review explaining basic concepts of forced magnetic reconnection. It is based on a celebrated model of forced reconnection suggested by J. B. Taylor. The standard magnetohydrodynamic (MHD) theory of this process has been pioneered by Hahm & Kulsrud (Phys. Fluids, vol. 28, 1985, p. 2412). Here we also discuss several more recent developments related to this problem. These include energetics of forced reconnection, its Hall-mediated regime, and nonlinear effects with the associated onset of the secondary tearing (plasmoid) instability.

    One of the issues facing valve maintenance personnel today deals with an appropriate methodology for installing and setting valve packing that will minimize leak rates, yet ensure functionality of the the valve under all anticipated operating conditions. Several variables can affect a valve packing's ability to seal, such as packing bolt torque, stem finish, and lubrication. Stem frictional force can be an excellent overall indicator of some of the underlying conditions that affect the sealing characteristics of the packing and the best parameter to use when adjusting the packing. This paper addresses stem friction forces, analytically derives the equations related to these forces, presents a methodology for measuring these forces on valve stems, and attempts to correlate the data directly to the underlying variables

    A catastrophe of the magnitude of the earthquake and tsunami that hit Chile not long ago, forces us to raise some questions that we will try to answer from a philosophical, ethical and responsibility viewpoints. An analysis of the basic principles of bioethics is also justified. A natural catastrophe is not, by itself, moral or immoral, fair or unfair. However, its consequences could certainly be regarded as such, depending on whether they could have been prevented or mitigated. We will identify those individuals, who have the ethical responsibility to attend the victims and the ethical principles that must guide the tasks of healthcare and psychological support teams. The minimal indispensable actions to obtain an adequate social and legal protection of vulnerable people, must be defined according to international guidelines. These reflections are intended to improve the responsibility of the State and all the community, to efficiently prevent and repair the material and psychological consequences of such a catastrophe.

    To identify the extent and nature of the problem and the main contributing factors to drink driving crashes; determine the current mechanisms in place, particularly in terms of legislation and its enforcement; and identify baseline data and relevant stakeholders. The situational assessment was based on the collection of secondary data from available reports and documents, in-depth interviews with key representatives at a central level, and field surveys in provinces. Vietnam has experienced phenomenal growth in motor vehicles, especially motorcycles, in the last decade (400%). This initially led to an increase in deaths from road crashes, but since 2006 the number has stayed fairly level according to police statistics. However, comparisons with health data suggest that the number of deaths is much higher and there are clearly a number of problems with the relevant data systems. Data on the percentage of drivers exceeding legal limits are not available, but police statistics indicated that drinking alcohol was a contributory factor in 7 percent of motor vehicle crashes. This is likely to be an underestimate, because the police and health services do not have the equipment to measure the blood alcohol concentration (BAC) levels of all drivers in crashes. Motorcycle riders and young people are in the high-risk groups. There are strict BAC limits starting at over zero and severe punishments for drunk drivers involved in serious crashes. However, the police do not have adequate manpower or equipment to conduct regular and frequent roadside checking for drivers who have been drinking. There have also been a number of education programs on road safety including drinking and driving, but these have not included sustained and intensive campaigns targeting the high-risk groups. The National Traffic Safety Committee (NTSC) is responsible for coordinating the relevant agencies but there is still a problem with lack of information sharing between agencies.

    1996-11-01

    The translation of the relativistic motion into the language of forces, proposed by the author (1995, Nuovo Cimento B 110 973), is employed to interpret the gyroscope precession in general relativity. The precession is referred to the comoving Frenet triad built up along the projection of the gyroscope's trajectory onto the 3-space of the local hypersurface-orthogonal observer. The contributions of the centrifugal, the gravitational and the dragging + Coriolis forces are identified respectively with the Thomas, the geodetic, and the gravitomagnetic components of precession. Explicit expressions are given for several simple types of motion in the Kerr (or simpler) field in order to show that the general formulae obtained are not only very simple, but also yield clear results in accord with intuition in concrete situations.

    Despite increased awareness, poor adherence to treatments for chronic diseases remains a global problem. Adherence issues are common in patients taking antihypertensive therapy and associated with increased risks of coronary and cerebrovascular events. Whilst there has been a gradual trend toward improved control of hypertension, the number of patients with blood pressure values above goal has remained constant. This has both personal and economic consequences. Medication adherence is a multifaceted issue and consists of three components: initiation, implementation, and persistence. A combination of methods is recommended to measure adherence, with electronic monitoring and drug measurement being the most accurate. Pill burden, resulting from free combinations of blood pressure lowering treatments, makes the daily routine of medication taking complex, which can be a barrier to optimal adherence. Single-pill fixed-dose combinations simplify the habit of medication taking and improve medication adherence. Re-packing of medication is also being utilized as a method of improving adherence. This paper presents the outcomes of discussions by a European group of experts on the current situation of medication adherence in hypertension.

    September 11 2001 attacks and following Anthrax mailings introduced emergent need for developing technologies that can distinguish between man made and natural incidents in the public health level. With this objective in mind, government agencies started a funding effort to foster the design, development and implementation of such systems on a wide scale. But the outcomes have not met the expectations set by the resources invested. Multiple elements explain this phenomenon: As it has been frequent with technology, introduction of new surveillance systems to the workflow equation has occurred without taking into consideration the need for understanding and inclusion of deeper personal, psychosocial, organizational and methodological concepts. The environment, in which these systems are operating, is complex, highly dynamic, uncertain, risky, and subject to intense time pressures. Such 'difficult' environments are very challenging to the human as a decision maker. In this paper we will challenge these systems from the perspective of human factors design. We will propose employment of systematic situational awareness research for design and implementation of the next generation public health preparedness infrastructures. We believe that systems designed based on results of such analytical definition of the domain enable public health practitioners to effectively collect the most important cues from the environment, process, interpret and understand the information in the context of organizational objectives and immediate tasks at hand, and use that understanding to forecast the short term and long term impact of the events in the safety and well being of the community.

    As technology continues to advance, services and capabilities become computerized, and an ever increasing amount of business is conducted electronically the threat of cyber attacks gets compounded by the complexity of such attacks and the criticality of the information which must be secured. A new age of virtual warfare has dawned in which seconds can differentiate between the protection of vital information and/or services and a malicious attacker attaining their goal. In this paper we present a novel approach in the real-time detection of multistage coordinated cyber attacks and the promising initial testing results we have obtained. We introduce INFERD (INformation Fusion Engine for Real-time Decision-making), an adaptable information fusion engine which performs fusion at levels zero, one, and two to provide real-time situational assessment and its application to the cyber domain in the ECCARS (Event Correlation for Cyber Attack Recognition System) system. The advantages to our approach are fourfold: (1) The complexity of the attacks which we consider, (2) the level of abstraction in which the analyst interacts with the attack scenarios, (3) the speed at which the information fusion is presented and performed, and (4) our disregard for ad-hoc rules or a priori parameters.

    The purpose of this work was to present an educational model developed in recent years entitled the "The Educational Situation Quality Model" (MOCSE, acronym in Spanish). MOCSE can be defined as an instructional model that simultaneously considers the teaching-learning process, where motivation plays a central role. It explains the functioning of an educational setting by organizing and relating the most important variables which, according to the literature, contribute to student learning. Besides being a conceptual framework, this model also provides a methodological procedure to guide research and to promote reflection in the classroom. It allows teachers to implement effective research-action programs to improve teacher-students satisfaction and learning outcomes in the classroom context. This work explains the model's characteristics and functioning, recent advances, and how teachers can use it in an educational setting with a specific subject. This proposal integrates approaches from several relevant psycho-educational theories and introduces a new perspective into the existing literature that will allow researchers to make progress in studying educational setting functioning. The initial MOCSE configuration has been refined over time in accordance with the empirical results obtained from previous research, carried out within the MOCSE framework and with the subsequent reflections that derived from these results. Finally, the contribution of the model to improve learning outcomes and satisfaction, and its applicability in the classroom, are also discussed.

    The requirement for energy worldwide is going to rise dramatically in the next few years and decades. Despite all developments of renewable energy sources, and despite the expansion of nuclear power in some industrialized countries and emerging countries, coal will turn out to be the key source of energy in the 21st century. Europe as a whole has a lot to offer which strengthens its position with respect to present and future requirements to be met in the construction of new power plants as well as in electricity and power supplies. As regards nuclear power in Germany, if it is to be given another chance, we must seek a dialog, pointing out that - nuclear power offers advantages in ensuring energy supply in Germany, given the development in the world energy markets; - nuclear power makes an important contribution to climate protection; - Germany's energy supply must be adapted to the global situation; - nuclear power offers opportunities in education, training, research and development; - nuclear power is contributing massively to our economic prosperity. The future viability of European power supply will not depend on the debate about nuclear power in Germany. The debate will be decided chiefly by the world market and on a European level. (orig.)

    The relationship between verbal and visual aspects of the analytic proceedings shows them blended integrally in the experiences of both patient and analyst and in contributing to the insights derived during the treatment. Areas in which the admixture of the verbal and visual occur are delineated. Awareness of the visual aspects gives substance to the operations of empathy, intuition, acting out, working through, etc. Some typical features of visual 'language" are noted and related to the analytic situation. As such they can be translated with the use of logic and consciousness on the analyst's part, not mere random eruptions of intuition. The original significance of dreams as a royal road to the unconscious is confirmed-but we also find in them insights to be derived with higher mental processes. Finally, dyadic aspects of the formation and aims of dreams during analysis are pointed out, with important implications for the analyst's own self-supervision of his techniques and 'real personality" and their effects upon the patient. how remarkable that Dora's dreams, all too belatedly teaching Freud about their transference implications, still have so much more to communicate that derives from his capacity to record faithfully observations he was not yet ready to explain.

    This is a qualitative research concerning on students’ creativity on problem posing task. The study aimed at describing the students’ creative thinking ability to pose the mathematics problem in structured situations with varied condition of given problems. In order to find out the students’ creative thinking ability, an analysis of mathematics problem posing test based on fluency, novelty, and flexibility and interview was applied for categorizing students’ responses on that task. The data analysis used the quality of problem posing and categorized in 4 level of creativity. The results revealed from 29 secondary students grade 8, a student in CTL (Creative Thinking Level) 1 met the fluency. A student in CTL 2 met the novelty, while a student in CTL 3 met both fluency and novelty and no one in CTL 4. These results are affected by students’ mathematical experience. The findings of this study highlight that student’s problem posing creativity are dependent on their experience in mathematics learning and from the point of view of which students start to pose problem.

    Full Text Available This article provides an overview of the current economic situation in Bosnia and Herzegovina. Beginning in the second half of 2008, macroeconomic conditions in B&H began precipitating a decline in economic activity. While the global financial crisis was among the factors contributing to this decline, it was far from the only factor. Problematic macroeconomic conditions were also a result of B&H’s own structural and political problems, caused largely by the shortcomings of a political entity comprising two autonomous entities. Due to such problems, the governments of B&H turned to the International Monetary Fund for assistance. This article analyzes the effects of the first two “stand by” arrangements made between the IMF and B&H and discusses implications for further, ongoing stand by arrangements made between the IMF and B&H. This paper also examines the lack of unified economic space between The Federation of Bosnia and Herzegovina and The Republic of Srpska, which has resulted not only in ineffective monetary policy but also in different fiscal and taxation systems between the two entities. While various existing analyses claim that B&H has little hope of resolving its economic woes due to its current political and economic structure, this article offers solutions and measures that, if successfully implemented, would lead to more efficient recovery and self-sustainable economic growth.

  19. Enhanced situational technologies applied to ship channels

    The Houston Ship Channel ranks as America's number one port in foreign tonnage by welcoming more than 50,000 cargo ships and barges annually. Locally 196,000 jobs, 5.5 billion dollars in business revenue and 213 million dollars in taxes are generated. Unfortunately, 32 days of each year vessel traffic stops for hours due to fog causing an estimated 40- 100 million dollars loss as ships idly wait in the channel for weather to clear. In addition, poor visibility has contributed to past vessel collisions which have resulted in channel closure, and associated damage to property and the environment. Today's imaging technology for synthetic vision systems and enhanced situational awareness systems offers a new solution to this problem. Whereas, typically these systems have been targeted at aircraft landing systems the channel navigation application provides a peripheral ground based market. This paper describes two imaging solutions to the problem. One using an active 35 GHz scanning radar and the other using a 94 GHz passive millimeter wave camera.
