    Full Text Available This paper discusses the present-day situation of the present tense and aorist in the Turkish dialects in the Republic of Macedonia. The country is separated by the Vardar river. The characteristics of the Turkish dialects, roughly, also shows differences inside these boundaries. On the left bank morphological present tense and on the right bank morphological aorist predominates. Present tense suffixes in the northern dialects are /-i/, /-Ay/, /-y/ and in some eastern dialects /-iy/. These suffixes are used both as semantic present tense and as semantic aorist markers. In these dialects morphological aorist marker is almost never used. In the southern dialects, morphological aorist marker covers both semantic present tens and semantic aorist. In these dialects, definitely there is no morphological present tense marker. Compared to standard Turkish, there is a shortage of the present tense and aorist marker variants. In the negative forms of the morphological present tense always is used the /-y/ and in the negative forms of the morphological aorist, as it is in standard Turkish, always is used the /-z/ marker.

  3. Processing of verb tense

    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.

    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.

    Full Text Available Sabine Iatridou (2000 and Katrin Schulz (2014 defend accounts of the past tense in subjunctive conditionals according to which the past tense has a modal reading that excludes the world of utterance or some set of epistemically possible worlds. I argue here that these views give an unsatisfactory treatment of certain subjunctive conditionals that contain embedded indicative clauses pertaining to the actual world. http://dx.doi.org/10.3765/sp.8.12 BibTeX info

  13. Values of Present Perfect Tense and Past Simple Tense in Inquieta Compañía by Carlos Fuentes

    Directory of Open Access Journals (Sweden)

    Katja Seljak Adimora

    2012-12-01

    Full Text Available The article focuses on the contrast between Present Perfect Tense and Past Simple Tense, both in theory and in the literary Hispanic American text Inquieta Compañía (2004 by Carlos Fuentes. The typical use of these tenses in Mexican Spanish, some exclusive and others shared with Peninsular Spanish, are presented. The author presents the frequency of these tenses in different Spanish dialects. Although Present Perfect Tense is less used than Past Simple Tense, in the Mexican dialect as well as in Peninsular Spanish, it is not disappearing, but its use is limited.

  14. Tense Operators on Spaces of Numerical Events

    Chajda, Ivan; Länger, Helmut

    2014-10-01

    Spaces of numerical events were introduced for the sake to establish a propositional logic of physical phenomena. Since physical phenomena are variable in time, it is a natural task to develop temporal logic for this description. Hence we adopt the concept of tense operators used in classical propositional logic and in several sorts of non-classical one (e. g. Lukasiewicz many-valued logic, intuitionistic logic etc.). It turns out that the full set of states on a given space of numerical events can serve as a time scale if it is equipped with a suitable relation of time preference. A construction of tense operators is developed and a certain representation is derived. Finally, tense operators on spaces of numerical events whose elements have only the values 0 or 1 are characterized.

  17. Sequence of tenses: playing with possibilities

    Bohdan Ulašin

    2012-12-01

    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.

  18. Dynamic stability of forklift trucks in cornering situations: parametrical analysis using a driving simulator

    Science.gov (United States)

    Lemerle, P.; Höppner, O.; Rebelle, J.

    2011-10-01

    This paper describes the examination of the vehicle dynamics and stability of four-wheeled forklift trucks (FLTs) in cornering situations. Cornering at excessive speed is one major reason for fatal accidents with forklifts caused by lateral tipover. In order to increase the lateral stability of this kind of working machinery, the influence of certain important design properties has been studied using an appropriate vehicle simulation model and a driving simulator. The simulation model is based on a multi-body system approach and includes submodels for the propulsion system and the tyres. The driving behaviour of the operator has not been modelled. Instead, a driving simulator has been built up and a real human driver was employed for ensuring adequate and realistic model input. As there have not been any suitable standardised test manoeuvres available for FLTs, a new driving test has been developed to assess the lateral stability. This test resembles the well-known J turn/Fishhook turn, but includes a more dynamic counter-steering action. Furthermore, the dimensions of the test track are defined. Therefore, the test is better adapted to the driving dynamics of forklifts and reflects the real driver behaviour more closely. Finally, a parametrical study has been performed, examining the influence of certain important technical properties of the truck such as the maximum speed, the position of centre of gravity, rear axle design features and tyre properties. The results of this study may lead to a better understanding of the vehicle dynamics of forklifts and facilitate goal-oriented design improvements.

    2016-01-01

    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.

  1. Tense Usage in Selected Humanities and Science Dissertations

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    Frančiška Trobevšek Drobnak

    1990-12-01

    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.

  3. 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.

  4. FURTHER NOTES FOR A CONTRASTIVE AND DIDACTIC APPROACH TO THE USE OF THE PRESENT PERFECT TENSE VS. THE PAST TENSE

    Directory of Open Access Journals (Sweden)

    Constantin MANEA

    2010-11-01

    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. The contribution presents the main tenses involved in the broader picture of the English tenses and verbal structures related, in a way or other, to the past – viz. the Past Tense Simple, the Past Tense Progressive, the Present Perfect Simple Tense, and the Present Perfect Progressive Tense –, as well as the main differences (in meaning, grammatical collocation and communicative implications between the Present Perfect Tense and the Past Tense. The author’s remarks could hopefully contribute to

  5. 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.

    2017-12-01

    Full Text Available Among aspect of studies on second language acquisition, IL is one of the most important one. To date research on IL features has provided benefits to the study of second language learning in particular to EFL classroom. The present study explored IL verb tense system to indicate present, past, and future events employed by Indonesian learners of English as a foreign language. Empirical data were 444 ill-formed utterances elicited through free compositions from the EFL learners. Error analysis and IL analysis were used as analytical tool for data analysis. The results indicate the students have developed their own grammatical system to express present, past, and future events. Whilst their IL system was typified by a number of non-targetlike variants, this study provides evidence of the systematicity of IL as well as a model of particular IL systems, i.e. Indonesian EFL learners.

    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.

    relations under the scope of operators. When Prior, however, disclosed the invention of tense-logic to Smart, it is clear from the correspondence that Smart did not find Prior’s tensed operators convincing. Indeed, it turns out that Smart warned Prior against presenting tense-logic at the John Locke...... Lectures. Two questions are raised with regard to Smart’s warning: Why did Smart warn Prior against presenting tense-logic at the John Locke Lectures, and why was Prior’s tense-logic so well received? An argument is tentatively given based on the novelty of Prior’s tense-logical operators to account...

  10. Taking times out: Tense logic as a theory of time

    Science.gov (United States)

    Pashby, Thomas

    2015-05-01

    Ulrich Meyer's book The Nature of Time uses tense logic to argue for a 'modal' view of time, which replaces substantial times (as in Newton's Absolute Time) with 'ersatz times' constructed using conceptually basic tense operators. He also argues against Bertrand Russell's relationist theory, in which times are classes of events, and against the idea that relativity compels the integration of time and space (called by Meyer the Inseparability Argument). I find fault with each of these negative arguments, as well as with Meyer's purported reconstruction of empty spacetime from tense operators and substantial spatial points. I suggest that Meyer's positive project is best conceived as an elimination of time in the mode of Julian Barbour's The End of Time.

    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.

  16. Production of Verb Tense in Agrammatic Aphasia: A Meta-Analysis and Further Data.

    Science.gov (United States)

    Faroqi-Shah, Yasmeen; Friedman, Laura

    2015-01-01

    In a majority of languages, the time of an event is expressed by marking tense on the verb. There is substantial evidence that the production of verb tense in sentences is more severely impaired than other functional categories in persons with agrammatic aphasia. The underlying source of this verb tense impairment is less clear, particularly in terms of the relative contribution of conceptual-semantic and processing demands. This study aimed to provide a more precise characterization of verb tense impairment by examining if there is dissociation within tenses (due to conceptual-semantic differences) and an effect of experimental task (mediated by processing limitations). Two sources of data were used: a meta-analysis of published research (which yielded 143 datasets) and new data from 16 persons with agrammatic aphasia. Tensed verbs were significantly more impaired than neutral (nonfinite) verbs, but there were no consistent differences between past, present, and future tenses. Overall, tense accuracy was mediated by task, such that picture description task was the most challenging, relative to sentence completion, sentence production priming, and grammaticality judgment. An interaction between task and tense revealed a past tense disadvantage for a sentence production priming task. These findings indicate that verb tense impairment is exacerbated by processing demands of the elicitation task and the conceptual-semantic differences between tenses are too subtle to show differential performance in agrammatism.

    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 This article is a response to Groenewald’s 2014 article, ‘A re-evaluation of tense in isiZulu’. Sub-themes identified in Groenewald’s article and explored in this exposé in the light of an array of recently published research on the topic of tense are: the suitability of the distinction between absolute and relative tense and the use of the term ‘absolute tense’; the appropriateness of defining tense in terms of deixis; the remoteness distinctions in terms of past and future tenses generally distinguished in the Bantu languages with particular reference to isiZulu; the semantic significance of the use of the so-called short and long forms of the present and past tenses of isiZulu and the naming of the individual tenses.

    Full Text Available Abstract One of the admirable methods to compose stories in Persian verse and prose, is the present Tense verbs in the meaning of past tense. This grammatical point has been hidden in the grammarian and stylist's point of view although it has been repeatedly mentioned in the texts and this point has been not mentioned in the grammatical books but some of the investigators and literati have pointed out it in their correction works. We mention their sayings: firstly, Allame Qazvini, doubtfully, mentions the interferential times of the verbs and inconsistencies of the Tenses in the correction of texts of Jahangoshaye – Joveini Book. He writes in the second footnote 2-3, that the verb Mikonam( I do is in the form of present Tense but its meaning is in the simple past Tense. As it has been observed, in the most old books the form of the verb is in the present tense but its meaning is in simple Tense ( Joveini, 1367, p. 357. Later, Fruzanfar in the correction of grammatical notes of ouhadoddin Kermani's Manaqeb, points to this point and counted it of the Eltefat Literary art ( Fruzanfar, 1347. P. 61 Mohammad Roushan informed this grammatical rule and he writes in the introduction of his book: the application of this kind of verb that is not on the basis of the dependent and independent verbs (Khagushi, 1361, p. 24. Yusofi in his correction on Bidpay Stories points to this grammatical point that it has been hidden of correctors of the book. Ha says that this grammatical point is the prose characteristic of the book. He adds that the characteristic includes in the present stories (Yusofi, 1364, p. 36. Finally, Dr. shfi'ee in his valuable notes on the Mateqol altei their mentions that this style of telling stories – the verb in the present Tense- is less in verse but the verbs in the same meaning and forms were used in old Persian as in the present time but there were inconsistence in the time and the form of the verbs in the past and the grammarians

  6. Perfectionistic Cognitions: Stability, Variability, and Changes Over Time.

    2018-02-01

    The construct of perfectionistic cognitions is defined as a state-like construct resulting from a perfectionistic self-schema and activated by specific situational demands. Only a few studies have investigated whether and how perfectionistic cognitions change across different situations and whether they reflect stable between-person differences or also within-person variations over time. We conducted 2 studies to investigate the variability and stability of 3 dimensions of perfectionistic cognitions while situational demands changed (Study 1) and on a daily level during a highly demanding period of time (Study 2). The results of both studies revealed that stable between-person differences accounted for the largest proportion of variance in the dimensions of perfectionistic cognitions and that these differences were validly associated with between-person differences in affect. The frequency of perfectionistic cognitions increased during students' first semester at university, and these average within-person changes were different for the 3 dimensions of perfectionistic cognitions (Study 1). In addition, there were between-person differences in the within-person changes that were validly associated with concurrent changes in closely related constructs (unpleasant mood and tense arousal). Within-person variations in perfectionistic cognitions were also validly associated with variations in unpleasant mood and tense arousal from day to day (Study 2).

  9. 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.

  11. Epistemic uncertainty: Turkish children with specific language impairment and their comprehension of tense and aspect.

    Yarbay Duman, Tuba; Topbaş, Seyhun

    2016-11-01

    Impairments in tense morphology are characteristic of English-speaking children with specific language impairment (SLI). Recent studies have investigated the role that aspect plays in the difficulties found in tense morphology. It has been suggested that children with SLI are less sensitive to aspect and its interaction with tense than typically developing (TD) children. Profound impairment in past tense morphology compared with the present in this population was explained by a breakdown in the association between event completion information and past tense. To date, research on tense morphology in this population has not examined all three tense conditions in a single study. To examine whether monolingual Turkish-speaking children with SLI exhibit deficits in comprehending tense and aspect morphology, and, if so, whether these deficits are restricted to completed events (past tense) or also occur for incomplete non-past events (future and present tense). A sentence-picture matching task was administered to 36 monolingual Turkish-speaking children: 13 with SLI (mean age = 6;9 years) and 23 age-matched TD children (mean age = 6;5 years). Upon hearing a sentence, each child had to select between a target (past, present or future) and a distracter picture. Tense and aspect information could only be established from verb morphology. The SLI group had lower accuracy than the TD group on all test conditions. For both groups, present tense had the highest accuracy scores. Performance scores within the SLI group showed the following hierarchy from easy to difficult: present > future > past. Turkish children with SLI have deficits in comprehending tense and aspect morphology. Although comprehending past was more difficult than non-past (present and future), future was more difficult to comprehend than the present. This disassociation between two non-past incomplete events indicates that the underlying difficulties comprehending (past) tense-aspect is not restricted to event

  12. 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.

  15. 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.

    2016-01-01

    Purpose The aim of this study was to determine the influence of anatomical conditions on primary stability in the models simulating posterior maxilla. Methods Polyurethane blocks were designed to simulate monocortical (M) and bicortical (B) conditions. Each condition had four subgroups measuring 3 mm (M3, B3), 5 mm (M5, B5), 8 mm (M8, B8), and 12 mm (M12, B12) in residual bone height (RBH). After implant placement, the implant stability quotient (ISQ), Periotest value (PTV), insertion torque (IT), and reverse torque (RT) were measured. Two-factor ANOVA (two cortical conditions×four RBHs) and additional analyses for simple main effects were performed. Results A significant interaction between cortical condition and RBH was demonstrated for all methods measuring stability with two-factor ANOVA. In the analyses for simple main effects, ISQ and PTV were statistically higher in the bicortical groups than the corresponding monocortical groups, respectively. In the monocortical group, ISQ and PTV showed a statistically significant rise with increasing RBH. Measurements of IT and RT showed a similar tendency, measuring highest in the M3 group, followed by the M8, the M5, and the M12 groups. In the bicortical group, all variables showed a similar tendency, with different degrees of rise and decline. The B8 group showed the highest values, followed by the B12, the B5, and the B3 groups. The highest coefficient was demonstrated between ISQ and PTV. Conclusions Primary stability was enhanced by the presence of bicortex and increased RBH, which may be better demonstrated by ISQ and PTV than by IT and RT. PMID:27588215

  10. A confusion of tenses: Health screening and time.

    Science.gov (United States)

    Stronge, Paul

    2013-07-01

    The article seeks to contribute to a re-evaluation of the role played by the contemporary health screen by exploring its relation to tense and time. Mobilizing data around operational aspects of screening for type 2 diabetes (T2D) alongside more general historical and conceptual perspectives, it challenges implicit assumptions that the screen represents either a momentary 'cut' in a longer process or a singular event with its own durational integrity. In contrast, the article argues, two distinct kinds of temporally related processes merge within any given screening episode. On one hand a rich heterogeneity of durations - physiological, technical, social, experiential - is involved. Yet this multiplicity is afforded unity and coherence insofar as the screen becomes a 'thick' site of intersection or fusion between the three major tenses. Drawing on aspects of the thought of Bergson and Deleuze as well as Mol's notion of 'ontological politics', the article reconceptualizes the screen as a 'leaky receptacle' for temporal complexity and teases out pragmatic implications of such a re-envisioning.

  11. Assessment of implant stability during various stages of healing placed immediately following extraction in an overdenture situation

    2017-01-01

    Full Text Available To assess the implant stability during different stages of healing in an immediate loaded implant soon after extraction. A 73-year-old female came with a chief complaint of bad smell and irritation in her lower front gum region. On examination, she was found to be completely edentulous in the maxillary arch and partially edentulous in the mandibular arch with only the canines present bilaterally. The posterior mandibular ridge was severely resorbed and hence could not be treated with a conventional mandibular complete denture. Considering the age of the patient and the preference of only a single surgical visit, we decided to plan for a conventional maxillary denture against an implant supported mandibular overdenture with two implants placed immediately after extraction of canines. The stability of these implants was assessed during the early phases of healing with the help of a resonance frequency analysis method (RFA using Osstell ISQ™. During the healing phase, implant stability quotient (ISQ values decrease by 4–5 values after installation with the lowest values at the 1st week postplacement. Following this, the ISQ values increased steadily for all implants up to 16 weeks. No significant differences were noted over time. At placement, the mean ISQ values at 33 and 43 regions were 74 and 75.2, respectively. The mean lowest ISQ values recorded at the 1st week were 58.8 and 65.4, respectively. At 16 weeks, the mean ISQ values were 70.5 and 67.9, respectively. The survival of such immediately placed implants, which are later used as overdenture supported implants, are highly predictable when the surgical and prosthetic part is done meticulously. However, there needs future studies oriented to understand better the healing pattern of immediately placed implants in extraction sockets, which would guide the clinician with the optimal loading time.

    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.

  14. Conditional and future tense impairment in non-fluent aphasia

    Background:Morphological errors of tense and agreement are salient in agrammatic aphasia. The PADILIH predicts impairments in discourse linking that translate to greater difficulties in referring to a past event time than to a future or a present event time. In Catalan, the Periphrastic conditional...... between verb forms that refer to an irrealis future event (Simple conditional and Future). We also assessed whether problems in time reference extend to individuals with non-fluent aphasia that are not typical agrammatic Broca aphasia. Methods & Procedures:A sentence completion task that included 60...... sentences (20 per type) of equal length in a Conditional structure (if-sentences) was designed. We tested three sentence types: Periphrastic conditional, Simple conditional and Future. The task was administered to nine participants with non-fluent aphasia and nine age-matched non-brain-damaged participants...

  15. Fast neutron breeder reactor Rapsodie - situation of physics, hydraulic, thermal and dynamics studies and studies of stability early in 1963

    1964-01-01

    Early in 1963, it was necessary to make a choice among the two fuels examined for Rapsodie: the UPuMo alloy with double cladding, Nb and stainless steel, and the UO 2 -PuO 2 mix oxide. This report presents the results of the studies effected with the two types of fuel. We reconsider at first the different models which have been studied and we give a detailed description of the alloy and oxide cores as they are envisaged early in 1963. We give then the most important physics performances of the two cores: neutron flux and spectrum, reactivity of the compensation find safety rods, neutrons balance, specific power, effective fraction of delayed neutrons, lifetime of the prompt neutrons, reactivity coefficient. We describe the hydraulic studies and experiments which have been done concerning the two cores. We discuss the criteria adopted as basis for the flow calculations. We give the results of pressure drop and sub-assembly lifting, force measurements, and vibration and pin flow distribution experiments. We discuss the constants utilized for the thermal calculations and we give the temperatures of sodium and alloy or oxide fuel, the temperature increases due to the hot points, and the limitation of the oxide fuel burn-up, originated by the pressure of the fission gases. We treat the hypotheses having been utilized for the dynamics calculations and we describe the different accidents which have been studied. We give the results of the calculations for every accident and each fuel, and we show fuel melting or sodium boiling can be avoided, even in case of the most pessimistic hypotheses, by modifying reactor characteristics (shim-rod reactivity or power of the reactor with only one cooling circuit). The reactor stability has been evaluated with the hypotheses utilized for the dynamics calculations, except of the Doppler coefficient which was intentionally increased. We show that the alloy and oxide cores are stable for every envisaged reactor power. (authors) [fr

    Compositionality is a critical and universal characteristic of human language. It is found at numerous levels, including the combination of morphemes into words and of words into phrases and sentences. These compositional patterns can generally be characterized by rules. For example, the past tense of most English verbs (“regulars”) is formed by adding an -ed suffix. However, many complex linguistic forms have rather idiosyncratic mappings. For example, “irregular” English verbs have past tense forms that cannot be derived from their stems in a consistent manner. Whether regular and irregular forms depend on fundamentally distinct neurocognitive processes (rule-governed combination vs. lexical memorization), or whether a single processing system is sufficient to explain the phenomena, has engendered considerable investigation and debate. We recorded event-related potentials while participants read English sentences that were either correct or had violations of regular past tense inflection, irregular past tense inflection, syntactic phrase structure, or lexical semantics. Violations of regular past tense and phrase structure, but not of irregular past tense or lexical semantics, elicited left-lateralized anterior negativities (LANs). These seem to reflect neurocognitive substrates that underlie compositional processes across linguistic domains, including morphology and syntax. Regular, irregular, and phrase structure violations all elicited later positivities that were maximal over right parietal sites (P600s), and which seem to index aspects of controlled syntactic processing of both phrase structure and morphosyntax. The results suggest distinct neurocognitive substrates for processing regular and irregular past tense forms: regulars depending on compositional processing, and irregulars stored in lexical memory.

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.

    2011-03-01

    Most neuroimaging studies examining verb morphology have focused on verb tense, with fewer examining agreement morphology, and no previous fMRI studies have investigated distinctions between past and present tense inflection. However, models of language representation and processing suggest differences in where these inflections are instantiated in the phrase structure as well as differences in the linguistic functions they serve, suggesting unique neural networks for these forms. In addition, results of available neuroimaging studies of grammatical morphology vary considerably due to methodological differences. Some studies have used overt production tasks, whereas others have used covert tasks. In the present study we examined brain activation associated with past tense and present tense/agreement morphology under overt and covert production conditions in 13 healthy adults using an event-related functional magnetic resonance imaging (fMRI) design. Production of verbs inflected for past tense (V + -ed) and present tense/agreement (V -s) was elicited using temporal adverbs (i.e. Yesterday, Nowadays). Results showed that in healthy adults inflecting both past tense and agreement morphology (compared to a verb stem production condition) recruited not only left inferior frontal structures, but also motor and premotor cortices, and posterior parietal regions. Activation also was observed in the basal ganglia, thalamus, and the cingulate gyrus. Past tense and present tense/agreement recruited partially overlapping tissue in these regions, with distinctions observed for the two forms in frontal and parietal brain areas. We also found that activation varied with task demands, with more extensive frontal activation noted in the overt compared to the covert verb inflection task. These results are consistent with the hypothesis that the neural signatures for verb inflection differ from that for verb stems alone and involve a distributed frontal and parietal network of brain

    Full Text Available Although many researchers have worked on the role of feedback in immersion programs on second language learners' production, still little is known about the role of different types of immediate feedback on the grammatical accuracy of learners' production. When, where and with who different types of immediate feedback such as prompts and recasts and their different subcategories might be appropriate? The purpose of the present research was to know which types of immediate oral feedback could better help Iranian EFL learners to produce the correct form of the tense markers of their target language English. One of the primary objectives of the present study was to examine the effects of two types of oral feedback namely explicit correction and implicit or-choice feedback on Iranian EFL learners' production of different tense markers in English. The results were in favor of explicit correction over implicit or-choice feedback in helping learners to produce correct grammatical tense markers.

    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

    Children with specific language impairment (SLI) vary widely in their ability to use tense/agreement inflections depending on the type of language being acquired, a fact that current accounts of SLI have tried to explain. Finnish provides an important test case for these accounts because: (1) verbs in the first and second person permit null subjects whereas verbs in the third person do not; and (2) tense and agreement inflections are agglutinating and thus one type of inflection can appear without the other. Probes were used to compare the verb inflection use of Finnish-speaking children with SLI, and both age-matched and younger typically developing children. The children with SLI were less accurate, and the pattern of their errors did not match predictions based on current accounts of SLI. It appears that children with SLI have difficulty learning complex verb inflection paradigms apart from any problem specific to tense and agreement.

    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.

  10. Role of aspect in understanding tense: an investigation with adolescents with SLI.

    Stuart, Nichola J; van der Lely, Heather

    2015-01-01

    Morphosyntax has been well researched in specific language impairment (SLI) and there is general agreement that children with SLI have particular difficulties with tense-marking. Less well researched is the role that aspect plays in the difficulties found in tense-marking, especially as tense and aspect are often confounded in English. Initial investigation of the understanding of aspect in preschool children with SLI suggests that they are less sensitive to aspect and its interaction with tense than typically developing (TD) children. It is unclear, however, what is the developmental trajectory of their understanding of aspect and its interaction with tense and whether these difficulties are still found in older children and adolescents with SLI. To investigate comprehension of the grammatical aspect contrast between completed events using the simple past tense -ed/irregular (perfective grammatical aspect) and ongoing events using the past progressive (imperfective grammatical aspect). The role of lexical aspect was also investigated through the balanced use of verbs that were inherently telic (i.e. have a natural end-point) and verbs that required the addition of prepositional phrase for a telic interpretation when used in the perfective aspect condition. A sentence-picture matching task was administered to 10 participants with SLI (aged 12;10-16;8 years) and 30 language ability matched TD children who were split into three groups (mean ages: 5;10, 7;4 and 9;2). Adult-like performance was found by all groups on the perfective aspect condition, but only by the oldest group of TD children on the imperfective aspect condition. The performance of the group with SLI was consistent with their much younger language ability matched TD children in their understanding of the progressive -ing when used to describe ongoing events that have taken place in the past. The lexical aspect of the telicity of the verbs was not found to have any significant effect on performance

    Full Text Available Fuel oil flyash (FFA produced in power and water desalination plants firing crude oils in the Kingdom of Saudi Arabia is being disposed in landfills, which increases the burden on the environment, therefore, FFA utilization must be encouraged. In the current research, the effect of adding FFA on the engineering properties of two indigenous soils, namely sand and marl, was investigated. FFA was added at concentrations of 5%, 10% and 15% to both soils with and without the addition of Portland cement. Mixtures of the stabilized soils were thoroughly evaluated using compaction, California Bearing Ratio (CBR, unconfined compressive strength (USC and durability tests. Results of these tests indicated that stabilized sand mixtures could not attain the ACI strength requirements. However, marl was found to satisfy the ACI strength requirement when only 5% of FFA was added together with 5% of cement. When the FFA was increased to 10% and 15%, the mixture’s strength was found to decrease to values below the ACI requirements. Results of the Toxicity Characteristics Leaching Procedure (TCLP, which was performed on samples that passed the ACI requirements, indicated that FFA must be cautiously used in soil stabilization.

  3. Language development of bilingual children; The acquisition of tense and aspect in an Italian-Indonesian child: A case study

    Directory of Open Access Journals (Sweden)

    Antonia Soriente

    2013-04-01

    Full Text Available This paper describes the development of temporal expressions in a bilingual child acquiring two typologically distinct languages: Italian and Indonesian.  These languages differ from one another in the way tense and aspect are encoded and it is interesting to observe what kind of cross-linguistic influence one language system has on the other. Italian verbs are heavily inflected for person, number as well as for tense, aspect and mood, whereas, in Indonesian, the encoding of tense and aspect is lexical rather than morphological; moreover encoding is optional when the context is sufficiently clear. This means that tense and aspect in Indonesian is often marked pragmatically rather than grammatically. This paper considers the interference effects that result from simultaneously acquiring these two typologically distinct systems.

    2004-08-01

    The relationship between children's language acquisition and their nonverbal intelligence has a long tradition of scientific inquiry. Current attention focuses on the use of nonverbal IQ level as an exclusionary criterion in the definition of specific language impairment (SLI). Grammatical tense deficits are known as a clinical marker of SLI, but the relationship with nonverbal intelligence below the normal range has not previously been systematically studied. This study documents the levels of grammatical tense acquisition (for third-person singular -s, regular and irregular past tense morphology) in a large, epidemiologically ascertained sample of kindergarten children that comprises 4 groups: 130 children with SLI, 100 children with nonspecific language impairments (NLI), 73 children with low cognitive levels but language within normal limits (LC), and 117 unaffected control children. The study also documents the longitudinal course of acquisition for the SLI and NLI children between the ages of 6 and 10 years. The LC group did not differ from the unaffected controls at kindergarten, showing a dissociation of nonverbal intelligence and grammatical tense marking, so that low levels of nonverbal intelligence did not necessarily yield low levels of grammatical tense. The NLI group's level of performance was lower than that of the SLI group and showed a greater delay in resolution of the overgeneralization phase of irregular past tense mastery, indicating qualitative differences in growth. Implications for clinical groupings for research and clinical purposes are discussed.

  5. 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.

    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.

  7. Texas situation

    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

  8. STABILIZED ERRORS: ATTRIBUTED PROBLEM IN TIMED AND NON-TIMED ARGUMENTATIVE WRITING

    Full Text Available This study is a case study seeking the relation between the errors students made in timed and non-timed argumentative writing. The use of good English language influences whether or not the students can develop their claim. The finding shows that students have fifteen types of stabilized errors, the dominant of which are verb tense, word choice and spelling. On language form, the stabilized errors mostly occur are omission and addition. Some students also show stabilized errors with reference to the negative transfer of their first language. In addition, the type of writing task results in different number of stabilized errors. Despite the favor on non-timed writing, some students show more careful language use without using the computer’s spelling and grammar check. However, the type of writing task does not affect the number of errors as there is no significant difference between the two writing tasks. It supports the fact that post systematic errors are caused by several factors such as language transfer, intralingual interference and sociolinguistic situation. Accordingly, process approach writing is needed in which learners are given chance to make progress and, as suggested by Krashen’s theory, to become optimal Monitor users.

    Full Text Available The paper focuses on assessing the growth and production of a mixed oak/hornbeam forest stand established by combined regeneration in 1940 to 1942. The stand is situated at an altitude of 460 m. Since 1961, it is left to its natural development. The 25–year–old stand was characterized as an individually mixed, both diameter- and height-differentiated pole-stage stand. The proportion of tree species was as follows: sessile oak 77 %, hornbeam 19 %, birch 1 %, lime 1 %, black poplar 1 %, wild cherry tree, wild service tree, and field maple. During 41 years of measurements, the proportion of oak slightly decreased to 76 %, on the other hand, the proportion of hornbeam increased to 22%. The initial growing stock of the 25–year–old stand, 75 m3.ha−1, increased to 323 m3.ha−1 at an age of 66 years in 2008. At present, current volume increment ranged between 6.3 m3.ha−1.year−1 and 11.6 m3.ha−1.year−1 during years 1967 and 1998. Since the age of 61, the growth of the stand has decreased and then even ceased due to increased mortality of oak.

    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.

    ? This paper suggests that temporal logic, and in particular the hybrid logic corresponding to A.N.

The paper offers a general investigation of this suggestion...... illuminating the conceptual potential and also some of the open questions within the study of temporal logic. It is argued that the endeavour of the logic of time can be seen as the study of some important manifestations and structures of our tacit knowledge of time....

    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. ...

  14. Tense and plural formation in Welsh-English bilingual children with and without language impairment.

    Science.gov (United States)

    Chondrogianni, Vasiliki; John, Nerys

    2018-01-12

    Grammatical morphology has been shown to be problematic for children with specific language impairment (SLI) or developmental language disorder (DLD). Most research on this topic comes from widely spoken languages, such as English. Despite Welsh being the most extensively spoken indigenous in the UK after English, and Wales being the only official bilingual country in the UK, our knowledge about the morphosyntactic areas of Welsh that may pose problems for Welsh-speaking children with SLI is limited. Currently, Welsh-speaking speech and language therapists (SLTs) are heavily reliant on the use of informally translated English assessments. This can inadvertently result in a failure to take aspects of Welsh morphosyntax into account that are critical for the assessment and treatment of Welsh-speaking children. This is the first study to examine how Welsh-English bilingual children of early school age with typical development (bi-TD) and with SLI (bi-SLI) perform on production tasks targeting verbal and nominal morphology in Welsh. We targeted areas of Welsh morphosyntax that could potentially be vulnerable for Welsh-speaking children with or at risk of language impairment, such as tense marking and plural formation, and assessed their diagnostic potential. Twenty-eight Welsh-dominant bilingual children participated in the study: 10 bi-SLI and 18 bi-TD. They were administered three elicitation tasks targeting the production of verbal (compound and synthetic past tense) and nominal (plural) morphology in Welsh. The bi-SLI children performed worse than their bi-TD peers across all three tasks. They produced more uninflected verbs in the elicited-production task and were less likely to be prompted to produce the synthetic past, which is a concatenating, low-frequency form of the past tense. They also over-regularized less in the context of plural nouns, and when they did, they opted for high-frequency suffixes. By focusing on aspects of morphosyntactic development which

    Full Text Available The increasing demand for a high and homogeneous technological quality of common wheat (Triticum aestivum L. points out the necessity of improving wheat with by a higher protein (GPC and gluten content, strength of dough (W and dough stability. Among the current crop practices, late-season nitrogen (N fertilization, from heading to flowering, is generally considered the practice that has the most effects on the storage proteins and technological quality of the grain. In order to explore the influence late-season N application can have on the dough properties and on the formation of homogeneous lots in more detail, a research was set up between 2007 and 2013, over 6 growing seasons at different sites in North West Italy using the Bologna cultivar in each of the trials. Three different late-season N fertilization strategies were compared: T1, control without a late distribution of N; T2, foliar N fertilization at flowering; T3, top-dress granular soil fertilization at the beginning of heading. A randomized complete block experimental design with four replicates was adopted. The grain yield, GPC, W and P/L indexes were analyzed. Moreover, the rheological and enzymatic properties of the samples were studied using a Mixolab® analyser (Chòpin Technologies, Paris, France. Grain yield was found to be unaffected by the fertilization treatments, while the late N application (T2, T3 significantly increased GPC. Only the granular N fertilization (T3 increased the W index compared to T1, while the P/L index was not affected by any of the fertilization strategies. Furthermore, the T3 strategy was always more effective in reducing the variability of the W index than the T2 and the T1 strategies. Water absorption and dough development time were higher in T3, than in T1, while intermediate results were reached for T2. The effect of late-season N fertilization was also significant on the starch behaviour of the dough, as an increase in starch gelatinization and

  19. Production of subject-verb agreement, tense, mood, and negation in Italian agrammatic aphasia.

    2015-05-01

    At the group level, the results of the agrammatic participants are not consistent with any of the hypotheses discussed here. Contrary to the TUH, participants performed better on tense than on mood. The DMH cannot explain the observed, selective impairment of categories involving inflectional alternations (tense/agreement>mood. Results do not support the TPH, as the higher the category in the syntactic hierarchy (Neg>T(future/past>M (Cinque, 1999; Zanuttini, 2001, the better the performance of agrammatic participants. Lastly, results are at odds with the IFIH, because negation (+integration processes is better preserved than agreement (-integration processes. Analogous results are observed at the individual level. None of the available hypotheses can account for the patterns of performance of all the agrammatic participants. Their results, together with the production results of other agrammatic speakers in the literature, show that all possible patterns can be observed in agrammatism, and that a unitary account of the disorder is unlikely to succeed. We suggest that subject-specific characteristics (e.g., site/type/volume of brain damage, type/severity of language impairment, education, age and language-specific properties of functional categories (e.g., syntactic hierarchy, interpretability/involvement of integration processes, frequency may interact in determining the way in which (morphosyntactic impairments manifest themselves across agrammatic speakers and languages.

    Midodrine is an α-agonist prodrug of desglymidodrine used for the management of hypotension, and can also be used for hepatorenal syndrome and cirrhotic patients with tense ascites. The objective of the present work was to study the clinical pharmacokinetic parameters of midodrine and its active metabolite desglymidodrine in cirrhotic patients with tense ascites, which may help in dose selection and improve treatment outcome. This was a prospective, open-label, single-dose, parallel-group study. At first, a pilot study was performed on one healthy volunteer by taking serial blood samples at scheduled time intervals to validate the method of analysis and sampling times. The full study was then conducted by selecting 12 cirrhotic patients with tense ascites in one group and taking nine blood samples. We also selected five healthy volunteers as the control group and took 11 blood samples. Statistically significant differences were observed between the healthy volunteer group and the patients group in the area under the concentration versus time curve (AUC0-t) and maximum plasma concentration (Cmax) values of midodrine and desglymidodrine. Based on the results of the pharmacokinetic analysis, the patient group was further subdivided into those receiving the interacting drug ranitidine (five patients) and those not receiving the interacting drug (seven patients). Pharmacokinetic parameters of midodrine can differ significantly in cirrhotic patients with tense ascites from those in healthy individuals. Drug monitoring, dose adjustments, and drug-drug interactions should all be considered during therapy in this vulnerable patient group.

  9. 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

  10. I Tensed the Laws and the Laws Won: Non-Eternalist Humeanism

    Directory of Open Access Journals (Sweden)

    Marius Backmann

    Full Text Available ABSTRACT In this paper, I propose a variant of a Humean account of laws called "Open Future Humeanism" (OFH, which holds that since the laws supervene partly on future events, there are at any instant infinitely many possible future courses of events. I argue that if one wants to take the openness of the future that OFH proposes ontologically serious, then OFH is best represented within a growing block view of time. I further discuss some of OFH's problems which stem from the fact that in this view, there are no laws as long as time progresses. These problems can be solved by adding a temporal operator to the laws, so that at any instant, we get a set of tensed laws which held up to and including that instant.

  11. Strength of tensed and compressed concrete segments in crack spacing under short-term dynamic load

    Directory of Open Access Journals (Sweden)

    Galyautdinov Zaur

    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.

    2016-12-01

    Full Text Available The purpose of this study was to validate a procedure for sufficient exemplar training that can potentially lead to generalized responding. Based on this procedure, we taught four children with autism, generalized use of regular past tense verbs. We applied a non-concurrent multiple baseline design across the participants. The dependent variable was the number of verbs that needed to be trained for generalization to untrained verbs to occur. The number of verbs that needed to be trained varied considerably across participants as did the number of trials. We concluded that the procedure was validated and that it was easy to implement and it allows for individualization. We discuss the practical implications of our findings for teaching a wide range of skills using the same type of training procedure and data display strategies we provided in this study.

  14. 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.

  15. Grammar Is Differentially Impaired in Subgroups of Autism Spectrum Disorders: Evidence from an Investigation of Tense Marking and Morphosyntax.

    2017-01-01

    Deficits in the production of verbal inflection (tense marking, or finiteness) are part of the Optional Infinitive (OI) stage of typical grammatical development. They are also a hallmark of language impairment: they have been used as biomarkers in guiding genetic studies of Specific Language Impairment (SLI), and have also been observed in autism spectrum disorders (ASD). To determine the detailed nature of finiteness abilities in subgroups of ASD [autism with impaired language (ALI) vs. autism with normal language (ALN)], we compared tense marking abilities in 46 children with ALI and 37 children with ALN with that of two groups of nonverbal mental age (MA) and verbal MA-matched typically developing (TD) controls, the first such study described in the literature. Our participants' performance on two elicited production tasks, probing third-person-singular - s and past tense - ed , from the Rice/Wexler Test of Early Grammatical Impairment (TEGI, Rice and Wexler, 2001), revealed extensive deficits in the ALI group: their ability to correctly mark tense was significantly worse than their much younger TD controls', and significantly worse than that of the ALN group. In contrast, the ALN group performed similarly to their TD controls. We found good knowledge of the meaning of tense, and of case and agreement, in both ASD groups. Similarly, both ASD groups showed distributions of null or overt subjects with nonfinite and finite verbs in line with those found in young TD children. A key difference, however, was that the ALI group used (rather than simply omitted) the wrong tense in some sentences, a feature not reported in the OI stage for TD or SLI children. Our results confirm a clear distinction in the morphosyntactic abilities of the two subgroups of children with ASD: the language system responsible for finiteness in the ALN group seems to be functioning comparably to that of the TD children, whereas the ALI group, despite showing knowledge of case and agreement

Our participants' performance on two elicited production tasks, probing third-person-singular -s and past tense -ed, from the Rice/Wexler Test of Early Grammatical Impairment (TEGI, Rice and Wexler, 2001), revealed extensive deficits in the ALI group: their ability to correctly mark tense was significantly worse than their much younger TD controls', and significantly worse than that of the ALN group. In contrast, the ALN group performed similarly to their TD controls. We found good knowledge of the meaning of tense, and of case and agreement, in both ASD groups. Similarly, both ASD groups showed distributions of null or overt subjects with nonfinite and finite verbs in line with those found in young TD children. A key difference, however, was that the ALI group used (rather than simply omitted) the wrong tense in some sentences, a feature not reported in the OI stage for TD or SLI children. Our results confirm a clear distinction in the morphosyntactic abilities of the two subgroups of children with ASD: the language system responsible for finiteness in the ALN group seems to be functioning comparably to that of the TD children, whereas the ALI group, despite showing knowledge of case and agreement, seems

    Considerable research has investigated the role of verbal working memory in language development in children with and without language problems. Much less is currently known about the relationship between language and the declarative and procedural memory systems. This study examined whether these 2 memory systems were related to typically developing children's past tense and lexical knowledge. Fifty-eight typically developing children approximately 5 years of age completed a battery of linguistic and nonlinguistic tasks, including tests of vocabulary, past tense production, and procedural and declarative memory. The results showed that declarative and procedural memory were not correlated with either regular or irregular past tense use. A significant correlation was observed between declarative memory and vocabulary. The results of the study were not consistent with the view that the declarative and procedural memory systems support children's use of the regular and irregular past tense. However, evidence was found suggesting that declarative memory supports vocabulary in this age group.

  18. Some Peculiarities of the Use of Perfect Tense Forms in the Narration of the Holy Martyrs Boris and Gleb

    Full Text Available The paper deals with some results of the analysis of the perfect tense forms functioning in the copies of the Narration of the Holy Martyrs Boris and Gleb created in the 12th – 15th centuries. The relevance and urgency of this problem are determined by the ongoing debates on the semantic and functional status of this preterite. New data on representation of this verbal category in the above mentioned manuscript have been provided. The following texts have been in the focus of attention: the earliest extant copy of the Narration from the Assumption Collection of the 12th – 13th centuries; the copy of the second half of the 14th century from the Sylvester Codex; and the copy of the 15th century from the Book of Degrees of the Royal Genealogy. The complete set of examples of the perfect tense forms functioning has shown that the verbal form appeared in this literary manuscript due to the following reasons: 1 usage, as a rule, in the direct (or indirect discourse; 2 intention to avoid the homonymous forms of 2 and 3 person singular that occurred in the aorist paradigm; 3 interaction with present, imperative forms in the context. The later copies of the Narration reveal the expansion of the perfect tense forms usage, their penetration into the monologic narrative context. The conclusion on the stylistic nature of perfect tense forms as of an oral speech phenomenon has been made on the basis of the copies of the Narration that occurred at different times and the scientific literature on this problem.

  20. From Vitality to Vital Exhaustion and Other States of "Tense Tiredness": A New Biopsychosocial Risk Domain.

    Rozanski, Alan; Cohen, Randy

    2017-04-01

    Fatigue is a common prodromal symptom for various medical conditions, including acute myocardial infarction. Fatigue is also the core component of vital exhaustion, which consists of a specific triad: excessive fatigue, increased irritability, and feelings of demoralization. In this issue of Psychosomatic Medicine, Frestad and Prescott present a meta-analysis of 16 studies, involving 53,337 participants, which found vital exhaustion to be associated with an increased risk of incident coronary heart disease (CHD) and recurrent cardiac events among individuals with established CHD. After discussing methodological limitations of the studies included in this meta-analysis, we describe these findings in terms of a larger genre of risk that is biopsychosocial in origin and tied to two types of tiredness: "calm tiredness" and "tense tiredness." The former is regenerative, while the latter enhances disease risk. We propose that besides vital exhaustion, other symptoms of negative affect may combine with tiredness to produce increased clinical risk, such as the presence of depressed mood, an inability to relax or recover after work, and symptoms of burnout. We further propose that vital exhaustion can be considered as part of a larger paradigm, ranging from a positive state of vitality to a negative state of exhaustion of vitality. We conclude this editorial by emphasizing the importance of improving vitality and the need to clarify biobehavioral mechanisms that play a role in the association between vital exhaustion and adverse CHD outcomes. New interventions are needed that target reducing exhaustion and improving vitality for individuals at high risk of CHD.

The following hypotheses were investigated in this study: (a the second language transfer hypothesis (“L2 Status Factor” proposing that L2 impedes transfer from L1 into L3; (b the Cumulative Enhancement Model (“CEM”, proposing selective transfer from the previously learned languages, here L1 and L2; and (c the Full Transfer/Full Access Hypothesis (FT/FA, suggesting that the Universal Grammar (UG is available in acquiring the succeeding languages. The data were elicited via two experimental groups: one, Persian learners of English as a second language, and the other, Turkmen learners of English as a third language who had already acquired Persian as a second one. The structures tested in this study were simple present and present progressive tenses across the languages mentioned above. The L2 and L3 learners were tested at the initial state of their English acquisition. Data were gathered through grammaticality judgment and translation tasks. The results demonstrated that there is a significant advantage of L1 transfer in L3 acquisition.

    Full Text Available This research paper aims to explore the usage of the English Auxiliary “Be” Present Tense Verb, using corpus based method among Malaysian form 4 and form 5 students. This study is conducted by identifying and classifying the types of errors in the Auxiliary “Be” Present Tense verb in students’ compositions from the MCSAW corpus developed by (Mukundan&RezvaniKalajahi, 2013. 273 Form 5 sample essays and 295 Form 4 sample essays were taken from four different national schools where the schools were from four different states. The errors made in the written usage of the English Auxiliary “Be” Present Tense verb were evaluated and analyzed using the Wordsmith software version 4. The findings revealed that there are three types of errors which are the “Tense shift, Agreement and Misuse”. The results show that there were more errors made by the form 4s compared to the form 5s even though the difference of the frequencies of errors produced by both the levels were not of much difference. Therefore, the findings of this study can be used as a guide in enabling secondary school teachers to revise and be more prepared in their teaching instructions, materials and procedures. It will help teachers look into the possible remedial actions which could be taken into consideration to overcome the problems faced by Malaysian secondary school students in using the Auxiliary “Be” Present Tense verb.

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

    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

    Full Text Available The paper focuses on the types of representations of objective situations, that is, situations which are defined independently of the subject, by certain external perceptible circumstances and social expectations or rules. The author distinguishes between three types of objective situations in which children act: normative, developing and ambiguous. For each of these types there is a corresponding form of representation: sign, dialectical and symbolic. Each form is a product of the subject's cognitive activity, at the core of which lie cognitive abilities — a system of culturally specific means and ways of using them. The paper outlines normative and stabilizing abilities, transformation abilities, and symbolic mediation abilities. They help categorize different objects and features, enable transformation of situations and provide possibilities for orientation in ambiguous situations

    2014-10-07

    Despite the majority of patients with McArdle disease reporting symptoms including fatigue, cramps and episodes of myoglobinuria from early childhood, diagnosis is often delayed by several decades. Additionally, many individuals with rhabdomyolysis remain undiagnosed. The occurrence of symptoms during exercise, particularly isometric muscle contraction such as heavy lifting, is well known in McArdle disease. However, isometric muscle contraction that occurs with emotion is not recognised as exercise and may be missed as a trigger for rhabdomyolysis, potentially leading to a delay in diagnosis. Three patients are presented here, all with symptoms from childhood including episodes of rhabdomyolysis induced by tense emotional situations without physical exertion; two patients reported recurrent episodes while watching rather than playing football. The remaining patient developed rhabdomyolysis during a heated argument. These patients' histories emphasise the risk from sustained isometric muscle contraction that occurs in emotive situations for patients with McArdle disease. 2014 BMJ Publishing Group Ltd.

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

    Emergency responders need access to information but what counts as actionable information depends on their role, task, location, and other variables. For example, experts who have unique knowledge and experience and are called on to serve as scientific and teclmical responders, require correspondingly unique situation awareness in order to do their work. In our research-in-progress we leverage emerging and evolving web and digital library technologies to create personalized situation awareness tools that address the needs of these scientific and technical responders in real time, through focused information collection, extraction, integration, representation, and dissemination. We describe three personalized situation awareness tools in this paper: the Theme Awareness Tool (THEMAT), Social Awareness Tool (SAT), and Expertise Awareness Tool (EXPAT). The concepts and technologies we are developing in collaboration with experts apply to those who use the Web, in general, and offer an approach to the general issue of HCI design for emergencies.

    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.

  14. 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.

    Leonard, Laurence B.; Deevy, Patricia; Wong, Anita M.-Y.; Stokes, Stephanie F.; Fletcher, Paul

    2015-01-01

    Background Surprisingly little is known about the use of modal auxiliaries by children with specific language impairment (SLI). These forms fall within the category of grammatical morphology, an area of morphosyntax that is purportedly very weak in children with SLI. Aims Three studies were conducted to examine the use of modal auxiliaries by preschool-aged children with SLI. Methods & Procedures In each of the three studies, probe tasks were designed to create contexts that encouraged the use of modals to express the modality functions of ability and permission. In Study 1 and Study 3, English-speaking children participated. In Study 2, the participants were Cantonese-speaking children. In each study, three groups of children participated: A group exhibiting SLI, a group of younger typically developing children (YTD), and a group of (older) typically developing children (OTD) matched with the SLI group according to age. Outcome & Results In Study 1, we found that English-speaking children with SLI were as proficient as YTD children though less proficient than OTD children in the use of the modal can to express the modality functions of ability and permission. In Study 2, the same modality functions were studied in the speech of SLI, YTD, and OTD groups who were speakers of Cantonese. In this language, tense is not employed, and therefore the modality function could be examined independent of formal tense. Results similar to those of Study 1 were obtained. In Study 3, we again studied SLI, YTD, and OTD groups in English, to determine whether the children’s expression of ability differed across past (could) and non-past (can) contexts. The results for can replicated the findings from Study 1. However, the children with SLI were significantly more limited than both the YTD and OTD groups in their use of could. Conclusions These results suggest that most children with SLI have access to modality functions such as ability and permission. However, the findings of

    Midodrine is an α-agonist prodrug of desglymidodrine used for the management of hypotension. Midodrine has demonstrated usefulness in hepatorenal syndrome. The objective of the present work was to study the role of midodrine in patients with non-azotemic cirrhosis with tense ascites. This prospective randomized double blind placebo-controlled study was conducted on 67 non azotemic inpatients with liver cirrhosis and tense ascites (52 men and 15 women; age range, 45-72). One patient declined to participate in the study, 33 patients were randomly assigned to take midodrine hydrochloride, and 33 patients were randomly assigned to take placebo. Out of 67 enrolled patients, 60 patients (30: in midodrine group; 30: in placebo group) completed the study and 6 patients lost to follow up. Patients were assessed for patients’ characteristics, history of tapping their ascetic fluid, laboratory values, and Doppler parameters before and after the study. Average 24-h urine volume was assessed before and after the start of the study. significant reduction in body weight and abdominal girth was observed after 2 weeks of midodrine therapy. Midodrine appeared to be effective in lowering body weights and abdominal girths of non azotemic cirrhotic patients with tense ascites.

    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 Carsharing is becoming very popular in the western world as an effective method to contain rising prices of fuel and vehicles. It was brought about as a possible solution to the changing condition of growing economies and population where there is an increased need for travel but there is also a need for expense economizing. Due to its role in reducing fuel consumption, controlling pollution and traffic congestion, there is an increased usage of carsharing services as an alternative transportation option in big cities. Today, worldwide several different carsharing methods are being used. This paper examines the current situation of carsharing in the world and two initiatives for starting carsharing programs in Croatia. The main goal of this paper is to define what carsharing is, how successful it is in the world and if there is potential for it in Croatia. The most developed carsharing regions in the world are Western Europe and North America. In the last several years Asia, Australia and South America have started carsharing projects and have the biggest growth in members and vehicles. Carsharing is still not recognized in Croatia. There were a few initiatives for starting the program but they failed. In order to determine the possibility and potential of carsharing in Croatia it is necessary to conduct further market research.

    2012-01-01

    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.

  9. Memories in Present Tense: Affect and Spectrality in Contemporary Aquatic Imaginaries

    Directory of Open Access Journals (Sweden)

    Irene Depetris Chauvin

    2017-01-01

    Full Text Available Considering recent contributions on affective geographies and on the relationships between memory and spectrality, this papere analyses aquatic imaginaries in a corpus of audiovisual works from Argentina and Chile. Through water, El botón de nácar (Patricio Guzmán, 2015, Los durmientes, El exilio imaginado (Enrique Ramírez, 2012-2014, and Las aguas del olvido (Jonathan Perel, 2013 convey an “affective mapping” that creates ways of “being together” in the aftermath of loss. While Patricio Guzmán, Enrique Ramírez and Jonathan Perel refer to the so-called “death flights” – as both the Argentine and the Chilean dictatorship use oceans and rivers to “discard” the corpses of dissidents and “drown” the truth — their works also transgress conventional geographical and historical demarcations. These films, videos and installations subvert stabilizing cartographies and use anachronism to reflect on the contradictory meanings of water as a source of life, epicenter of cultures and cemetery not only for the victims of dictatorships, but also for indigenous groups or even contemporary migrants. Finally, these works insist on an “aesthetics of affect” that makes it possible to “touch” forgotten events, spaces or subjects and to connect different memories and geographies in the present.

  10. The Ellsberg psychoanalytic situation.

    Science.gov (United States)

    Bernal, V

    1976-01-01

    The author proposes to explore an event that received nationwide publicity through the Watergate investigation: the burglary of the office of a Los Angeles psychoanalyst believed to be treating Dr. Daniel Ellsberg. A brief questionnaire, with an accompanying letter, was mailed to all members of the American Psychoanalytic Association. It requested voluntary information on the reaction of their patients to the aforesaid particular event. The results of the study was then evaluated as serving hopefully an indirect inquiry into psychoanalytic practice. This paper is based on an adjusted sample of 861 respondent psychoanalysts, who reported on a total of 5,074 analysands. The resultant figures indicate that a high percentage of the analysand sample was silent concerning the office break-in during the eight-week period following the national publicity given the event. Of the small percentage of analysands that did present material concerning the event, the survey found that they were the patients of only 84 analysts of the entire sample of 861. The absence of reference to the Ellsberg Affair in so many patients may have been due to (1) the fact that analysts create an analytic situation which has a basic quality of interference such that events of this kind do not get communicated, and (2), more important, the fact that analysts through some defensive need failed to take cognizance of references to the Ellsberg Affair in dreams or in the latent content of the associations of their patients. A "natural" psychoanalytic experiment has been studied, and the results are offered for consideration.

    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.

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.

Relating to those errors there should be the preventing efforts by the teachers such as providing lots of examples of English and Indonesian sentences so that the students have greater understanding about the difference of those languages.

  17. Hands on the future: facilitation of cortico-spinal hand-representation when reading the future tense of hand-related action verbs.

    Reading action-related verbs brings about sensorimotor neural activity, suggesting that the linguistic representation of actions impinges upon neural structures largely overlapping with those involved in actual action execution. While studies of direct action observation indicate that motor mirroring is inherently anticipatory, no information is currently available on whether deriving action-related knowledge from language also takes into account the temporal deployment of actions. Using transcranial magnetic stimulation, here we sought to determine whether reading action verbs conjugated in the future induced higher cortico-spinal activity with respect to when the same verbs were conjugated in the past tense. We recorded motor-evoked potentials (MEPs) from relaxed hand and leg muscles of healthy subjects who were reading silently hand- or leg-related action, sensorial (non-somatic) and abstract verbs conjugated either in future or past tense. The amplitude of MEPs recorded from the hand was higher during reading hand-related action verbs conjugated in the future than in the past. No future-related modulation of leg muscles activity was found during reading leg-related action verbs. In a similar vein, no future-related change of hand or leg muscles reactivity was found for abstract or sensorial verbs. These results indicate that the anticipatory mirroring of hand actions may be triggered by linguistic representations and not only by direct action observation.

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.

  9. Cyber situation awareness and teamwork

    Directory of Open Access Journals (Sweden)

    Nancy J. Cooke

    2013-05-01

    Full Text Available Cyber analysis is a complex task that requires the coordination of a large sociotechnical system of human analysts working together with technology. Adequate situation awareness of such a complex system requires more than aggregate situation awareness of individuals. Teamwork in the form of communication and information coordination is at the heart of team-level situation awareness. In this position paper, we report observations from previously conducted cognitive task analyses that suggest that teamwork is lacking in many cyber analysis organizations. Communication is ineffective, team roles are inconsistent across organizations, reward structures and selection may thwart collaboration, and the environment is conducive to individual work. Suggestions for improving teamwork in the cyber domain are offered.

    Among the highly diverse population of persons living with HIV/AIDS are individuals with particularly challenging life circumstances that can be called "special situations." Substance abuse and homelessness are examples of special situations that require additional consideration when attempting to determine the appropriateness of prescribing complex antiretroviral regimens. When individual cases are examined in the context of relevant models of care and the principles of those models applied, such clinical decisions can be made with the patient. Withholding protease inhibitors from an entire population group, it is argued, is the epitome of practicing bad medicine.

    Zajenkowski, Marcin; Jankowski, Konrad S; Kołata, Daria

    2015-01-01

    In the present study, we examined mood changes following dancing. Previous works suggested that contextual factors may influence affective states; it has been shown that changes in mood following competition differ from those following recreational exercise. The study has been conducted in Warsaw, Poland. Mood was assessed before and after dance activity in three groups of ballroom dancers: recreational (n = 32) and competitive (n = 38) dancers doing ordinary training and competitive dancers taking part in a dance competition (n = 35). We observed a moderately positive change in recreational dancers doing ordinary training; they reported higher energetic arousal (EA) and hedonic tone (HT) and lower tense arousal (TA) after dance activity. In comparison dancers taking part in a competition were higher on TA before dancing and felt less pleasure after dancing than recreational and competitive dancers doing ordinary training; HT, TA and EA moderately decreased during competition. In general, the current study suggests that dance can elicit changes in mood; however, situational context has to be taken into consideration when explaining the influence of dance on mood.

    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.

  17. The German power supply situation

    International Nuclear Information System (INIS)

    Rauscher, K.

    2005-01-01

    The first key statement of this paper runs like this: The situation of power supply in Germany basically is good. However, two qualifications should be added: The current situation is still good. Power outages as a consequence of power plant failures of the kind experienced in other countries must not be expected to occur in Germany. German utilities work hard to offer this assurance also for the future. This is where politics comes in with the need to guarantee reliable framework conditions. After deregulation of the electricity market, reregulation resulting from government interventions is becoming potentially more and more problematic. Energy issues remain at the top of the political agenda, e.g. with the amendment to the Power Economy Act. This is a matter involving a variety of questions and projects on the part of legislators which require delicate handling because, in addition to the prices to be paid by consumers, they also involve as the most important factor the continuity of supply. Nuclear power today covers a major part of our baseload supply, in addition to lignite and hard coal which are used mainly in the medium-load range. Supported by the findings of recent studies, such as the dena Study, the Prognos and EWI Energy Report, the problem is how to replace this share reliably, in a way protecting the climate and economically viable, in line with the political conditions stipulating residual electricity outputs of nuclear power plants. Other countries can be seen to pursue different policies in using nuclear power. (orig.)

    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.

    This article discusses the present health situation in Tanzania, however, health system before independence, the colonial health system, has been the foundation on which the present health services in Tanzania are built upon. The population growth in Tanzania is high (3.2% in 1986), and projected to be 3.7% by the year 2,000. This high growth explains why it is difficult to achieve health objectives on the long term basis. Compounded to this is the economical crisis in the country. Child population in Tanzania account for about 47% of the total population in 1986. Maternal and Child Health Care services (MCHC) are discussed, with much emphasis on the child health care problems, and different programmes involved in improving child health care in the country. Problems of poor environmental sanitation are discussed including possible solutions for Tanzania. Tanzania, in this article, is urged to strengthen the existing health services in terms of staff, drugs, other supplies and equipment in order to give adequate health care to its people. Tanzania should also balance the distribution of resources between urban and rural so as to comply with the objective of the national health policy of comprehensive basic health services equitably to all within the limited available resources and to be able to reach the ultimate goal of health for all the people in the country by the year 2,000.

    Full Text Available This paper presents a synthesis of the third Critical Paths Seminar, held in Porto Alegre/Brazil in 2011, whose focus was extreme situations of gender violence. The extreme situations are human rights violations that include femicide or murder motivated by the situation of gender; LGBT murders, human rights violations of ethnic and racial minorities, sexual exploitation, violence to women in vulnerable situations and other violence caused by gender. The meeting objective was given space to share experiences, reflect critically and build strategies for facing violence and extreme situations resulting from gender systems.

  9. Sharing Space Situational Awareness Data

    The Commander, United States Strategic Command (CDRUSSTRATCOM) accepted responsibility for sharing space situational awareness (SSA) information/services with commercial & foreign entities from the US Air Force on 22 Dec 09 (formerly the Commercial & Foreign Entities Pilot Program). The requirement to share SSA services with non-US Government (USG) entities is derived from Title 10, United States Code, Section 2274 (2010) and is consistent with the new National Space Policy. US Strategic Command’s (USSTRATCOM’s) sharing of SSA services consists of basic services (Two-Line Elements, decay data and satellite catalog details) available on www.space-track.org and advanced services (conjunction assessment, launch support, etc) available with a signed agreement. USSTRATCOM has requested USG permission to enter into international agreements to enable SSA data exchange with our foreign partners. USSTRATCOM recently authorized Joint Functional Component Command for Space (JFCC SPACE) to share Conjunction Summary Messages (CSMs) with satellite owner/operators whose satellites have been identified as closely approaching another space object. CSMs contain vector and covariance data computed using Special Perturbations theory. To facilitate the utility of the CSMs, USSTRATCOM has and is hosting CSM Workshops to ensure satellite operators fully understand the data contained in the CSM in order to provide an informed recommendation to their leadership. As JFCC SPACE matures its ability to accept ephemeris data from a satellite operator, it will be necessary to automatically transfer that data from one security level to another. USSTRATCOM and Air Force Space Command are coordinating the integration of a cross domain solution that will allow JFCC SPACE to do just that. Finally, USSTRATCOM is also working with commercial and governmental organizations to develop an internationally-accepted conjunction assessment message. The United States Government (USG), specifically the

    Full Text Available La kafala, système de garantie sur l’étranger propre au monde arabe, produit au Liban un environnement normatif très contraignant pour les migrants non arabes dont elle organise l’immigration : en très grande majorité des femmes, originaires du Sri Lanka et des Philippines, employées domestiques. Elle impose sa temporalité d’institution globale à la migration, et se confronte aux autres temporalités qui structurent l’espace migratoire : celles des individus mobiles, dont la carrière migratoire s’encastre dans la hiérarchie socio-économique de la situation de départ, ainsi que dans dans la hiérarchie des contextes d’accueil ; la temporalité des industries d’émigration, qui développent une rationalité clivée qui leur est propre. Dans cet article, nous souhaitons mettre en scène ces tensions du temps migratoire dans des temporalités en conflit, en évoquant la négativité des rapports sociaux qui en résulte et les contournements normatifs que les migrants et les autres acteurs de cette scène globalisée opèrent dans la poursuite de leurs objectifs.The kafala is a system of guarantee for immigrants in the Arab world. In Lebanon, it produces a highly restrictive regulatory environment for non-Arab migrants; this institution organizes the import of a vast majority of women from Sri Lanka and the Philippines to become domestic employees. It imposes its - as defined - global institution's temporality to migration. It conflicts with the other temporalities that shape the migratory space : temporalities of individuals on the move, whose careers fit into the hierarchy of socio-economic baseline and into the hierarchy between host countries; temporalities of migration industry, that develop a cleaved rationality of their own. In this paper, we want to present the contradiction of migration time and temporalities, in order to understand the resulting negative social relationships. We also study the normative

    Full Text Available Situational language teaching (SLT is an effective instruction paradigm for English teaching in terms of providing vocabularies and sentence patterns with their frequent situations through learning materials. With the growth of educational technology, we need powerful and suitable techniques to embody SLT’s features in ubiquitous learning (u-learning and thus to benefit teachers and learners. Although researchers have proposed several innovative types of u-learning scenarios, the improved SLT paradigm in u-learning environment has been rarely investigated. This study indicated a framework of ubiquitous learning school to promote the concept of u-learning and employ SLT pedagogy in u-learning environment; it is called U-SLT. In order to support its innovation and provide situational learning services on demand, situational mashups was suggested to identify learners’ situation and learning requirement by means of integrating situation awareness with service mashups. The comparison between two u-learning modes, learning with situational mashups and learning without situation awareness support, were discussed. Experimental results showed that the students with the situational mashups support had a better learning performance and improved behaviours. Therefore, situational mashups was perceived to be a useful and desirable system for supporting U-SLT as well as the fundamental issue of a ubiquitous learning school.

  15. Managing and engineering in complex situations

    CERN Document Server

    Sousa-Poza, Andres

    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 ...

    1998-01-01

    Decontamination and decommissioning (D and D) activities require that personnel have access to all areas of structures, some of which are more than 40 years old. In many cases, these structures have remained in a standby condition for up to 10 years; few preventative maintenance activities have been performed on them because of lack of funding or a defined future plan of action. This situation has led to deteriorated building conditions, resulting in potential personnel safety hazards. In addition, leaky roofs allow water to enter the buildings, which can cause the spread of contamination and increase building deterioration, worsening the already unsafe working conditions. To ensure worker safety and facilitate building dismantlement, the assessment of roof stabilization techniques applicable to US Department of Energy (DOE) structures has become an important issue. During Fiscal year 1997 (FY97), a comprehensive reliability-based model for the structural stabilization analysis of roof system in complex structures was developed. The model consists of three major components: a material testing method, a deterministic structural computer model, and a reliability-based optimization, and probabilistic analyses of roof structures can be implemented. Given site-specific needs, this model recommends the most appropriate roof stabilization system. This model will give not only an accurate evaluation of the existing roof system in complex structures, but it will also be a reliable method to aid the decision-making process. This final report includes in its appendix a Users' Manual for the Program of Deterministic and Reliability Analysis of Roof Structures

  3. Situational pressures on aviation decision making: goal seduction and situation aversion.

    Bearman, Chris; Paletz, Susannah B F; Orasanu, Judith

    2009-06-01

    The context in which a decision is made can shape the decision process in important ways. Of particular interest here are 'strong' situations, that is, contexts where the situation itself exerts an influence on decision making. Borrowing concepts from field theory and approach/avoidance theory, this paper explores the influence of strong situations on pilot decision making. There were 28 pilots flying in Alaska who were interviewed using a critical incident technique where participants were asked to relate stories about challenging flying situations. A bottom-up qualitative analysis of reported social and psychological pressures revealed a range of types, including strong situations, which are described in this paper. Strong situations were mentioned in 67% of the interviews and included situations likely to motivate the pilot toward unsafe behavior (goal seduction) and situations likely to motivate the pilot away from safe behavior (situation aversion). Goal seduction situations included rescuing others, meeting a significant other, time-related constraints, financial pressures, and unspecified goal seduction; aversive situations included physical discomfort, not having maintenance or facilities for the airplane, and a lack of basic necessities (e.g., lodging) for the pilot. Goal seduction describes one broad, unspecified influence on pilot decision making, but situation aversion is also an important motivator for some pilots. Goal seduction and situation aversion may well underlie the phenomena of plan continuation errors, the tendency for pilots to continue despite evidence suggesting it is imprudent. This study suggests some specific factors that constrain decision making for pilots in challenging situations.

    2017-11-01

    Officials are expected to perform impeccably despite the wide range of stressors they experience. A stressor that officials frequently report is situation criticality. Situation criticality is comprised of score differential (i.e., more pressure in close games) and time remaining in a game (i.e., more pressure as time expires), which affects athletes' stress levels. The present study explored the effect of situation criticality on officials' stress levels. High school basketball officials (n = 108) with an average of 18.1 (SD = 11.2) years of officiating experience were given a survey packet containing game situations that varied in criticality. For each game situation (n = 9) officials completed the overall stress and appraisal portions of the Stress Appraisal Measure (SAM). Results revealed that situation criticality has an effect on officials' perceived stress levels. Both threat and challenge appraisals were positively correlated with perceived stress. Overall, these findings indicate that officials' stress levels fluctuate within games depending on score differential and time of game. The findings encourage officials to recognise and manage their stress, possibly through their appraisals. Additionally, the findings can affect the training of officials in the management of stress, as well as prompt the consideration of potential rule changes that reflect the increased situational demands on officials in critical situations (e.g., expanded instant replay).

    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.

    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.

    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

    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.

    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.

    2009-01-01

    Iodine deficiency disorders (IDD) constitute a severe public health problem in Sudan. IDD affects children and women throughout life. More than 2 out of 10 school age children have goiter. The prevalence reaches 40% in some regions of the country. Several interventional measures were introduced to control the IDD problem. While the situation with regard to production and supply of iodized salt was thus deteriorating, an Emergency Food Security and Nutrition Assessment Survey (EFSNA) revealed that the prevalence of IDD among adult women, as reflected in the presence of visible goiter, was as high as 25.5%. We have conducted a situation analysis survey in the Republic of Sudan to review the prevailing situation and suggest a benchmark that would help in developing effective control measures and in monitoring their implementations. SWOT analysis, questionnaire, focus groups discussion beside a combination of rapid assessment approach and qualitative method were used to critically evaluate the salt iodization situation in the country and assess the prevailing IDD situation in and propose a plan of action to overcome the bottlenecks. The survey concluded that Iodine deficiency affects children and women all through Sudan. The prevalence is even greater in some regions of the country and there is no supportive policy environment for successful universal salt iodization. To overcome this aggravated situation Sudan will need to conduct a baseline study to provide data on the prevalence of IDD, geographic distribution, knowledge, attitudes and practices relating to iodine deficiency. This will provide a benchmark that will help in developing effective control measures and in monitoring their implementation. The study recommended a set of actions to the government to overcome the prevailing situation and strengthening the current policy and implementation.

  12. THEORETICAL CONSIDERATIONS OF PRICE STABILITY AS PART OF THE FINANCIAL STABILITY

    Directory of Open Access Journals (Sweden)

    Magdalena RĂDULESCU

    2012-09-01

    Full Text Available Currently there are many authors who consider that the only objective of the central bank should be the price stability and between the respective objective and financial stability there is incompatibility. As far we are concerned, we subscribe the idea that between price stability and financial stability there are complementarities. And a strong argument in the favour of this position is also historical. Actually, many older or newer facts show that banking crises were often caused by the unfavourable macroeconomic situation coupled with the bad macroeconomic policies carried by the authorities. But, a monetary policy that aims the price stability reduces this risk. The truth is that the central banks have a series of tools that allow them to act for achieving both the objective of price stability, and that of the stability of financial sector. Although the financial stability is not, usually, an explicit objective for the modern central bank, the systematic financial instability can cancel their performances in achieving their major final objective: the price stability. Being that, because of the need that it creates to inject additional liquidity into the banking system, a crisis of the banking sector may directly affect the monetary stability. Here the mentioned complementarities arise between price stability and financial stability, although the achievement of the first does not necessarily involve the assurance of the last.

    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...

  18. The Bonding Situation in Metalated Ylides.

    Scharf, Lennart T; Andrada, Diego M; Frenking, Gernot; Gessner, Viktoria H

    2017-03-28

    Quantum chemical calculations have been carried out to study the electronic structure of metalated ylides particularly in comparison to their neutral analogues, the bisylides. A series of compounds of the general composition Ph 3 P-C-L with L being either a neutral or an anionic ligand were analyzed and the impact of the nature of the substituent L and the total charge on the electronics and bonding situation was studied. The charge at the carbon atom as well as the dissociation energies, bond lengths, and Wiberg bond indices strongly depend on the nature of L. Here, not only the charge of the ligand but also the position of the charge within the ligand backbone plays an important role. Independent of the substitution pattern, the NBO analysis reveals the preference of unsymmetrical bonding situations (P=C-L or P-C=L) for almost all compounds. However, Lewis structures with two lone-pair orbitals at the central carbon atom are equally valid for the description of the bonding situation. This is confirmed by the pronounced lone-pair character of the frontier orbitals. Energy decomposition analysis mostly reveals the preference of several bonding situations, mostly with dative and ylidic electron-sharing bonds (e.g., P→C - -L). In general, the anionic systems show a higher preference of the ylidic bonding situations compared to the neutral analogues. However, in most of the cases different resonance structures have to be considered for the description of the "real" bonding situation. © 2017 The Authors. Published by Wiley-VCH Verlag GmbH & Co.

    Human-computer interaction in multitask decisionmaking situations is considered, and it is proposed that humans and computers have overlapping responsibilities. Queueing theory is employed to model this dynamic approach to the allocation of responsibility between human and computer. Results of simulation experiments are used to illustrate the effects of several system variables including number of tasks, mean time between arrivals of action-evoking events, human-computer speed mismatch, probability of computer error, probability of human error, and the level of feedback between human and computer. Current experimental efforts are discussed and the practical issues involved in designing human-computer systems for multitask situations are considered.

    Full Text Available Introduction: Visit to the veterinary doctor for different reasons constitutes an unpleasant/negative or perhaps stressed experience for the dog. The stress could modify the physiological function and mask the symptom of an illness, or make the dog aggressive (1. Aims: Comparing the endocrine and behavioral response of dogs during the visit to the veterinary hospital and during activities in other places that are not related to stress (workplace, park. Materials and Methods: Six dog were taken in consideration, as indicators of stress there were used urinary cortisol, and behavioral observations. Results: Five of six dogs got high values of urinary cortisol after the visit to the veterinary clinic comparing with the values obtained in working spaces/park – areas that were familiar for dogs. Behavioral data’s have indicated a hesitating behavior at the entrance of the clinic and also in the examination room for all dogs, but the levels of intensity range individually for each dog. The results of the „Clinic Dog Stress Scale” classify behavior of dogs in following categories: 1 dog had score of 1 point that means a calm, relaxed dog; 2 dogs-3 points that means a middle level of stress, the dog is tense but cooperative; 2 dogs got 4 points-very tense, difficult to maneuver, and one dog 5 points that means a high level of distress.. Conclusion: Studding behavior relating with stress and the endocrine response at the veterinary visit it has importance for animal, owner and veterinary doctor. There is also a correlation between the stress manifestation and urinary cortisol.

  3. Situational Strategies for Self-Control

    2015-01-01

    Exercising self-control is often difficult, whether declining a drink in order to drive home safely, passing on the chocolate cake to stay on a diet, or ignoring text messages to finish reading an important paper. But enacting self-control isn’t always difficult, particularly when it takes the form of proactively choosing or changing situations in ways that weaken undesirable impulses or potentiate desirable ones. Examples of situational self-control include the partygoer who chooses a seat far from where drinks are being poured, the dieter who asks the waiter not to bring around the dessert cart, and the student who goes to the library without a cell phone. Using the process model of self-control, we argue that the full range of self-control strategies can be organized by considering the timeline of the developing tempting impulse. Because impulses tend to grow stronger over time, situational self-control strategies—which can nip a tempting impulse in the bud— may be especially effective in preventing undesirable action. Ironically, we may underappreciate situational self-control for the same reason it is so effective, namely that by manipulating our circumstances to advantage we are often able to minimize the in-the-moment experience of intrapsychic struggle typically associated with exercising self-control. The supreme art of war is to subdue the enemy without fighting.—Sun Tzu, The Art of War PMID:26817725

    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.

  12. Biology-inspired Architecture for Situation Management

    Jones, Kennie H.; Lodding, Kenneth N.; Olariu, Stephan; Wilson, Larry; Xin, Chunsheng

    2006-01-01

    Situation Management is a rapidly developing science combining new techniques for data collection with advanced methods of data fusion to facilitate the process leading to correct decisions prescribing action. Current research focuses on reducing increasing amounts of diverse data to knowledge used by decision makers and on reducing time between observations, decisions and actions. No new technology is more promising for increasing the diversity and fidelity of observations than sensor networks. However, current research on sensor networks concentrates on a centralized network architecture. We believe this trend will not realize the full potential of situation management. We propose a new architecture modeled after biological ecosystems where motes are autonomous and intelligent, yet cooperate with local neighborhoods. Providing a layered approach, they sense and act independently when possible, and cooperate with neighborhoods when necessary. The combination of their local actions results in global effects. While situation management research is currently dominated by military applications, advances envisioned for industrial and business applications have similar requirements. NASA has requirements for intelligent and autonomous systems in future missions that can benefit from advances in situation management. We describe requirements for the Integrated Vehicle Health Management program where our biology-inspired architecture provides a layered approach and decisions can be made at the proper level to improve safety, reduce costs, and improve efficiency in making diagnostic and prognostic assessments of the structural integrity, aerodynamic characteristics, and operation of aircraft.

  8. 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.

    Early in 1963, it was necessary to make a choice among the two fuels examined for Rapsodie: the UPuMo alloy with double cladding, Nb and stainless steel, and the UO{sub 2}-PuO{sub 2} mix oxide. This report presents the results of the studies effected with the two types of fuel. We reconsider at first the different models which have been studied and we give a detailed description of the alloy and oxide cores as they are envisaged early in 1963. We give then the most important physics performances of the two cores: neutron flux and spectrum, reactivity of the compensation find safety rods, neutrons balance, specific power, effective fraction of delayed neutrons, lifetime of the prompt neutrons, reactivity coefficient. We describe the hydraulic studies and experiments which have been done concerning the two cores. We discuss the criteria adopted as basis for the flow calculations. We give the results of pressure drop and sub-assembly lifting, force measurements, and vibration and pin flow distribution experiments. We discuss the constants utilized for the thermal calculations and we give the temperatures of sodium and alloy or oxide fuel, the temperature increases due to the hot points, and the limitation of the oxide fuel burn-up, originated by the pressure of the fission gases. We treat the hypotheses having been utilized for the dynamics calculations and we describe the different accidents which have been studied. We give the results of the calculations for every accident and each fuel, and we show fuel melting or sodium boiling can be avoided, even in case of the most pessimistic hypotheses, by modifying reactor characteristics (shim-rod reactivity or power of the reactor with only one cooling circuit). The reactor stability has been evaluated with the hypotheses utilized for the dynamics calculations, except of the Doppler coefficient which was intentionally increased. We show that the alloy and oxide cores are stable for every envisaged reactor power. (authors

    Full Text Available The purpose of this article is to underline the educative potential of the teaching method called «Situated learning». Thanks to the introduction of Tablets and iPads into the school environment, teachers have more instruments (i.e. interactive slides, video and audio support, Internet based sources to let knowledge, abilities and skills grow into their students’ mind: this is «Situated learning». Although the learning potential of these new learning instruments is clear, there must be the support of the students’ and teachers’ qualities and virtues (in particular the virtue of sharing knowledge, otherwise the whole potential would be nullified anyway: students with no will to learn will not learn, with or without an iPad, and the same is for a teacher with no will to teach.

    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.

    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)

    Because human cognition is creative and socially situated, knowledge accumulates, diffuses, and gets applied in new contexts, generating cultural analogs of phenomena observed in population genetics such as adaptation and drift. It is therefore commonly thought that elements of culture evolve through natural selection. However, natural selection was proposed to explain how change accumulates despite lack of inheritance of acquired traits, as occurs with template-mediated replication. It canno...

    2013-01-01

    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.

  5. Counterfactual Problem Solving and Situated Cognition

    Glebkin V.V.,

    2017-08-01

    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.

    Full Text Available Learning about decimals is an important part in mathematics. However at the same time, decimals are known as the  abstract numbers for students. Mostly in Indonesia, decimal is taught only as another notation for fractions or percentages. There are no meaningful references  for  them  such as  the  use of  concrete  situations. This study aimed at investigating one situation that enables students to learn about decimals in a meaningful way,  i.e.  measurement  activities.  Design research was chosen to reach the research goal. Realistic Mathematics Education (RME underlies  the design  of  context and activities. Our findings are that the students could discover decimals and  get meaningful situation from it. Measurement activities can promote the students’ notion of decimals which, then, provoke the students’ thinking into the idea of using number line as a model for placing the magnitude of decimals. Based on these findings, it is recommended that RME be implemented as an approach of teaching and learning decimals.Keywords: decimals, Realistic Mathematics Education (RME, number line, design research. DOI: http://dx.doi.org/10.22342/jme.2.2.750.215-230

    Patient management is becoming increasingly complex, particularly because of the growing prevalence ofchronic diseases and ageing populations. The Swiss health care system is fragmented and struggles to coordinate care provided by professionals from multiple disciplines or working for different institutions. Models to improve health care of complex situations are available that particularly advocate a coordinated team approach. This article presents an action-research designed to empower health professionals to manage complex situations in outpatient settings by means of this type of approach. Health professionals - good practice leaders in the medical and nursing fields in the Geneva Canton (Switzerland) - explored complex management situations, as well as facilitating components and obstacles. A team approach is essential to manage all of the patient's issues, to take the patient's priorities into account, and to work on a joint care plan. The legitimate role of each member of this team is highlighted, together with new roles for existing practices: informing and motivating the patient, highlighting and supporting care givers, coordination by nurses. The creation of such teams, and implementation of these roles involve new processes, which require financing of coordination as well as development of new methods of interdisciplinary management, particularly novel information technology tools.

    This paper discusses the problem of designing fault tolerant compensators that stabilize a given system both in the nominal situation, as well as in the situation where one of the sensors or one of the actuators has failed. It is shown that such compensators always exist, provided that the system...... is detectable from each output and that it is stabilizable. The proof of this result is constructive, and a worked example shows how to design a fault tolerant compensator for a simple, yet challeging system. A family of second order systems is described that requires fault tolerant compensators of arbitrarily...

  10. 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

  11. 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

  12. Patients' existential situation prior to colorectal surgery.

    2006-04-01

    The aim of this paper is to present a hermeneutic phenomenological study illuminating patients' existential situation prior to colorectal surgery. The intention was also to explore the value of the encounter between patient and nurse. Patients waiting for major surgery experience multifarious reactions. Emotions of anxiety, fears of the unknown, anaesthesia, cancer diagnosis and death can arise. Several earlier studies have reported the importance of information, coping strategies and the need to reduce anxiety and stress in relation to surgery. However, there is a lack of studies focusing on patients' existential situation in the preoperative phase. Conversational interviews were conducted with 28 patients 1 week before their surgery during autumn 2002. Analysis of the data was influenced by van Manen's existential themes: lived space/spatiality, lived body/corporeality, lived time/temporality and lived relation/relationality. Participants expressed either hope of increased spatiality or fear of restricted spatiality, according to whether they had a benign or malign diagnosis. Statements about lived time were also related to the diagnosis. Patients waiting for surgery for a benign diagnosis could use the time to relax and gather energy, while malignancy gave them high levels of anxiety and stress. Lived body experiences showed the ambivalence felt in entrusting one's body to professionals. Statements about lived relations drew attention to the need for considerate caregivers to enhance feelings of security and continuity. The existential situation of patients in a preoperative context was shown to be a state of uncertainty with regard to lived space, body, time and relation. The significance of meeting and talking to the nurse did not appear in the statements. The nurse was invisible. If nurses were to employ the existential themes proposed by van Manen in preoperative encounter with patients, their need for care might be more clearly identified and affirmed.

  13. Investigating Situational Interest in Primary Science Lessons

    Pupils' interest has been one of the major concerns in science education research because it can be seen as a gateway to more personalised forms of interest and motivation. However, methods to investigate situational interest in science teaching and learning are not broadly examined. This study compares the pupils' observed situational interest and their expressed situational interest. One class of Finnish fourth-graders (N = 22, age 9-10 years) participated in a heat transfer lesson. The lesson encompassed an interactive demonstration with a thermal camera, teacher-led discussions and the conduct and presentation of a collaborative inquiry task. Pupils expressed their interest levels (scale: 1 = very boring, 5 = very interesting) by using an electronic response system called a 'clicker'. The measurement took place 15 times during the lesson, with 1 measurement being just a rehearsal. The lesson was video recorded, and visible aspects of interest at the measurement time points were analysed. Reported and observational data were compared. In most cases, the observations did not yield data compatible with the pupils' own evaluations, indicating that most pupils' expressed interest is not easily interpreted through observation of their facial expressions and behaviour. In general, the interest of the group as a whole seems to diminish during the lesson. We argue that in order to maintain and increase pupils' interest, their evaluations should be taken into account in lesson planning. Video-based research might also be further enriched and validated by employing the participants' own expressions. The clicker is a suitable means of collecting primary pupils' experiences concerning their interest levels.

  14. 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.

    While a plethora of data describes homeless women's demographic characteristics and health status, a paucity of data exists on homeless women's perceptions of their housing situation. This exploratory-descriptive study of 70 shelter-residing women expands knowledge of homeless women. Content analysis of focus groups revealed that homelessness meant loss of autonomy-marginal control over their lives and uncertainly about their own and their children's future. Loss of autonomy was manifested as mental strain: feeling depressed, worried, and scared. They were especially concerned about the impact of shelter-living on their children. Shelter-living was not viewed as child-friendly.

Several factors may contribute to the problems of chemotherapy, including differences in the epidemiology of the disease, difficulties in the diagnosis and staging of the infection, availability, distribution and pharmacologic properties of drugs, standardization of treatment regimens, response to therapy, follow-up period, and relapses and clinical trials. The new therapeutic approaches include the development and approval of new drugs, the use of new therapeutic regimens, the study of drug combinations, and the development of new formulations.

    Digital re-presentation of indigenous knowledge remains an absurdity as long as we fail to deconstruct the prevalent design paradigm and techniques continuously re-framing technology within a western epistemology. This paper discusses key challenges in attempts of co-constructing a digital...... representation based on experiences from a longitudinal community-centred research project in rural Africa. In a quest to shape design from a locally situated viewpoint, we co-design a 3D visualization of an African village with its inhabitants.

    Full Text Available Under the current conditions of conducting international economic relations, there is a risk of failing to accomplish the monetary policy objectives due to reasons pertaining to the mechanisms that convey shocks cross-border. The conceptual review of object definition, under such conditions, leads to the necessity of attaching to them these risks of unfulfillment; this requires an additional chapter of macroeconomic policy design, chapter that identifies the possible risks emerging from the integrated cross-border regime of the European economies, as well as the possible solutions to absorb such shocks. This implicitly presumes the quantification of the whole phenomenon or risk emergence and of its possible effects, with the view to determine the effort necessary to be undertaken in order to absorb the associated shock.

    Jian, Kuo-Di; Nygard, Kendall E.

    1999-10-01

    This paper explores approaches and issues of developing practical and useful software agents that will communicate and response to their environment. A Multi-AGent architecture that uses SItuation Calculus (MAGSIC) to produce execution plans is designed from scratch. Based on this architecture, a software agent framework that can be reused by agent development is implemented. At present, this framework does not include all the features that are proposed. The framework is tested on Silicon Graphics Inc.'s IRIX Unix machine and PC Linux machine. To achieve automation, a high level language called Resource Programming Language that includes decision constructs, agent communication using KQML performatives, and other features is invented. MAGSIC has some unique characteristics. It is simple in architecture and small in line of code, yet supports a reasoning unit and scales well. An agent implementation like Java Agent Template only supports agent communication but does not support the scripting and reasoning unit. MAGSIC is founded upon a declarative knowledge representation (situation calculus) and clean semantics, equipped with a simple yet powerful approach to procedural attachments (scriptlet). Procedural attachments are tightly, yet flexibly, integrated with the knowledge representation and the reasoning, taking the form of knowledge metadata that annotates the procedural resource. MAGSIC also supporting moving scriptlet and can support mobile agents as well.

    2005-05-01

    Sensor management in support of situation assessment (SA) presents a daunting theoretical and practical challenge. We demonstrate new results using a foundational, joint control-theoretic approach to SA and SA sensor management that is based on three concepts: (1) a "dynamic situational significance map" that mathematically specifies the meaning of tactical significance for a given theater of interest at a given moment; (2) an intuitively meaningful and potentially computationally tractable objective function for SA, namely maximization of the expected number of targets of tactical interest; and (3) integration of these two concepts with approximate multitarget filters (specifically, first-order multitarget moment filters and multi-hypothesis correlator (MHC) engines). Under this approach, sensors will be directed to preferentially collect observations from targets of actual or potential tactical significance, according to an adaptively modified definition of tactical significance. Result of testing this sensor management algorithm with significance maps defined in terms of target's location, speed, and heading will be presented. Testing is performed against simulated data, and different sensor management algorithms including the proposed are compared.

  14. Fukushima 2015: situational analysis and perspectives

    International Nuclear Information System (INIS)

    Jouette, Isabelle; Le Ngoc, Boris

    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

  16. Unattended ground sensor situation assessment workstation

    Energy Technology Data Exchange (ETDEWEB)

    Jeppesen, D.; Trellue, R.

    1997-04-01

    Effective utilization of unattended ground sensors (UGSs) in a theater reconnaissance, surveillance, target acquisition, and kill assessment environment requires that a human operator be able to interpret, and collectively assess, the significance of real time data obtained from UGS emplacements over large geographical regions of interest. The products of this UGS data interpretation and assessment activity can then be used in the decision support process for command level evaluation of appropriate courses of action. Advancements in both sensor hardware technology and in software systems and processing technology have enabled the development of practical real time situation assessment capabilities based upon information from unattended ground sensors. A decision support workstation that employs rule-based expert system processing of reports from unattended ground sensors is described. The primary goal of this development activity is to produce a suite of software to track vehicles using data from unattended ground sensors. The situational assessment products from this system have stand-alone utility, but are also intended to provide cueing support for overhead sensors and supplementary feeds to all-source fusion centers. The conceptual framework, developmental architecture, and demonstration field tests of the system are described.

  17. Situating math word problems: the story matters.

    Science.gov (United States)

    Mattarella-Micke, Andrew; Beilock, Sian L

    2010-02-01

    In two experiments, we explored how the situation model of a math story problem impacts math problem performance. Participants completed multiplication story problems in which a set of objects was associated with or dissociated from a protagonist, making them more or less accessible in memory during answer retrieval. On the basis of previous findings that the sum of two numbers interferes with retrieval of their product, the number of objects in the math problem was either highly interfering ("9" for 4 x 5) or less interfering ("8" for 4 x 5) for multiplication retrieval in the problem. Participants made more errors in problem solving when highly interfering numerical content was associated with the protagonist and, thus, foregrounded. Moreover, the lower one's working memory, the bigger this effect. In sum, small changes in the situation model of a math story problem can harm performance. These changes shift the balance of factors that influence math performance away from math knowledge and toward individual differences in general cognitive capacity.

  18. Situational factors and attitudes toward voluntary euthanasia.

    Science.gov (United States)

    MacDonald, W L

    1998-01-01

    This study examines how attitudes toward voluntary euthanasia vary across categories of four situational factors: (1) type of assistance; (2) type of assistant; (3) type of illness; (4) age of the patient. The data, based on a random sample of 514 adult residents of Ohio, indicate that more active assistance is favored over less active assistance, and that voluntary euthanasia for cancer patients receives more support than does voluntary euthanasia for victims of Alzheimer's disease. The findings also suggest that, for persons who do not strongly adhere to the belief that life belongs to God, physician-assistants are preferred over nonphysician-assistants, and that voluntary euthanasia for children receives less support than does voluntary euthanasia for adults. For those who strongly adhere to the belief that life belongs to God. however, these two situational factors have less of an influence. At the microlevel, the findings appear to reflect a concern about safeguarding patients' autonomy in the decision-making process, and a concern about authoritative control of the procedure of voluntary euthanasia. At the macrolevel, the findings suggest that the influence of cultural ideology on a social movement's direction is not independent, but is instead moderated by the internal dynamics and struggles of movement organizations. This is indicated by the finding that movement leaders' attitudes toward active assistance on the part of the physician are more consistent with the attitudes of physicians than with the attitudes of the public.

  19. Dynamic stabilization of imploding liquid metal liner

    Itoh, Yasuyuki; Fujiie, Yoichi

    1979-01-01

    The rotational stabilization has been proposed against the Rayleigh-Taylor instability of the imploding liquid metal liner. In this paper, the discussion is made on the possibility of the dynamic stabilization by applying the oscillating azimuthal magnetic field in addition to the axial field. In contrast to the rotational stabilization, the required (field) energy for this stabilization is also used for the liner driving or the plasma confinement. In the analysis, the liner subjected to the acceleration is assumed to be infinitely long, at rest and have the situation at the start of the implosion or turnaround. At turnaround, the existence of the plasma is taken into account. The perturbed motion of the liner is discussed with a linear stability analysis. Results are as follows: (1) The dynamic stabilization at the start of the implosion is possible if the distance from the conducting wall to the liner outer surface is comparable with or less than the liner thickness. (2) At turnaround, the stability is improved with decreasing the ratio of the plasma radius to that of the liner inner surface however the kink mode (m = 1) cannot be suppressed. (author)

    2016-01-01

    Full Text Available The article is dedicated to one of the most pressing problems of our time — migration. Depopulation, population ageing, falling birth rate among the indigenous population creates conditions when migration becomes one of the most important sources of population growth in developed countries. Despite the fact that the problems depopulation can’t be solved only through migration, it is impossible to manage the situation without migrants, otherwise population will decline even more rapidly. The article analyzes particularities of migration in Russia, especially focusing on migration in Moscow. The main emphasis is made on the problems of interaction between migrants and the host community, or more precisely on the attitudes towards migrants among Muscovites. There is a high level of anti-immigrant and xenophobic attitudes among Moscow’s residents, which points to the necessity to overcome migrantophobia, promote tolerance, establish cultural dialogue between migrants and the indigenous population of the region. Negative consequences of xenophobia are analyzed, which pose a threat to Russian stability and security. A lot of attention is paid to such feature of contemporary migration as the increasing proportion of women among migrants — the feminization of migration, problems and prospects that follow it. In conclusions, the author relies on the existing statistical data, as well as the results of sociological research, conducted both on the national and regional levels.

    2017-12-01

    Full Text Available The aim was to understand the experiences of pregnant women in prison situation. We conducted a qualitative and descriptive study in a female prison in the State of São Paulo/Brazil, with 14 pregnant women and we used the content analysis technique grounded on psycho-emotional approaches. We identified the categories: Search for Self-Protection, Guilt Feeling, Building the New Identity. The experience in jail meant solitude, fear, impotence, and resignation. There are restrictions on family relationships, social conviviality, food supplement, privacy and on the right to sleep/rest, besides the impediment to exercise motherhood. Women demonstrated guilt and pain due to the privation to experience maternity and breastfeeding, besides the fear to lose their child’s custody. The women had to adjust themselves to the new reality to live in prison. We conclude that pregnant inmates try self-protection to survive the losses and the affection and social disruptions.

    1994-01-01

    This paper presents the environmental situation in Armenia with particular reference to (1) air, water, and soil pollution; (2) common and photochemical smog in the capital city, Yerevan, and other major cities; (3) household and industrial waste; (4) distribution of contaminated food imported from regions affected by the Chernobyl accident; (5) wasteful depletion of natural resources; (6) lack of a continuous monitoring of the environment and the public health; (7) absence of filtering equipment, and; (8) the extinction of plant and animal species. Armenia is currently living under an economic blockade which makes even elementary environmental protection projects such as water treatment difficult to accomplish. Even more important, the blockade may force the opening of the Armenian nuclear reactors at Medzamor leading to questions such as waste management. Medzamor was closed after the 1988 earthquake because it is located on a fault line

    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

    2006-11-01

    In this paper we present an approach to conceiving of, constructing and comparing the concepts developed and used by geographers, environmental scientists and other earth science researchers to help describe, analyze and ultimately understand their subject of study. Our approach is informed by the situations under which concepts are conceived and applied, captures details of their construction, use and evolution and supports their ultimate sharing along with the means for deep exploration of conceptual similarities and differences that may arise among a distributed network of researchers. The intent here is to support different perspectives onto GIS resources that researchers may legitimately take, and to capture and compute with aspects of epistemology, to complement the ontologies that are currently receiving much attention in the GIScience community.

    Margarit, G.; Tabasco, A.; Gomez, C.

    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.

    2014-07-01

    Globally over 1.3 billion people do not have access to electricity and 2.6 billion people rely on the traditional use of biomass for cooking. Energy access is one of the major challenges of the 21. century as it is a lever for both economic and human development, at individual and national level. Moreover, energy access represents a high-potential market and offers a lot of opportunities for private companies and industrials. In this publication, ENEA lays out the current situation of energy access (actors, actual and future needs, existing technological solutions, markets). The publication addresses the main issues energy access has to face: energy price, equipment financing, distribution, scale-up, and environmental performances

    2000-06-01

    Although social isolation has been shown to have a negative long-term influence on feelings of loneliness, there has been no systematic investigation of situational influences on loneliness. The purpose of this study was to compare scores on the UCLA Loneliness Scale, the loneliness which people feel prior to performing a novel task, with those on the same scale after engaging in the task. 31 college freshmen were divided into those working alone (n = 14) and those working in a group (n = 17). Those who performed the novel task within a group felt significantly less lonely after than prior to performing the task and reported less loneliness than the students who performed the same task in isolation. An important implication of this study is that group interaction may directly and immediately reduce the amount of loneliness individuals feel.

    Ten years ago the Republic of Korea enacted the National Health Promotion Act, setting the stage for health promotion action in the country. A National Health Promotion Fund was established, financed through tobacco taxes, which is now one of the largest in the world. However, despite abundant financial resources, the infrastructure needed to plan, implement, coordinate and evaluate health promotion efforts is still underdeveloped. Currently, health promotion capacity mapping efforts are emerging in Korea. Two international capacity mapping tools have been used to assess the Korean situation, namely HP-Source and the Health Promotion Capacity Profile, which was developed prior to the sixth Global Conference of Health Promotion, held in August 2005 in Bangkok, Thailand. The article summarizes and discusses the results of the capacity mapping exercise, highlights its challenges and suggest ways to improve the accuracy of health promotion capacity mapping.

    Increased interconnection and loading of the power system along with deregulation has brought new challenges for electric power system operation, control and automation. Traditional power system models used in intelligent operation and control are highly dependent on the task purpose. Thus, a model...... of explicit principles for model construction. This paper presents a work on using explicit means-ends model based reasoning about complex control situations which results in maintaining consistent perspectives and selecting appropriate control action for goal driven agents. An example of power system...... for intelligent operation and control must represent system features, so that information from measurements can be related to possible system states and to control actions. These general modeling requirements are well understood, but it is, in general, difficult to translate them into a model because of the lack...

    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.

    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.

    Innovative Engineering and Consulting (IEC) Infrared Systems, a leading developer of thermal imaging systems and night vision equipment, received a Glenn Alliance for Technology Exchange (GATE) award, half of which was in the form of additional NASA assistance for new product development. IEC Infrared Systems worked with electrical and optical engineers from Glenn's Diagnostics and Data Systems Branch to develop a commercial infrared imaging system that could differentiate the intensity of heat sources better than other commercial systems. The research resulted in two major thermal imaging solutions: NightStalkIR and IntrudIR Alert. These systems are being used in the United States and abroad to help locate personnel stranded in emergency situations, defend soldiers on the battlefield abroad, and protect high-value facilities and operations. The company is also applying its advanced thermal imaging techniques to medical and pharmaceutical product development with a Cleveland-based pharmaceutical company.

  3. Register as the Situational Variety of Language

    Directory of Open Access Journals (Sweden)

    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.

  4. The sanitation situation: a case study.

    In India, interviews with and observations of members of 100 households with a latrine were done in the towns of Satna and Khandwa, in Madhya Pradesh State, to examine the sanitation situation, to evaluate the maintenance and performance of the 2 pit pour-flush water seal (PF) latrines of poor households, and to recommend actions to improve the sanitation situation. The upper caste Hindus and Muslims tended to use the PF latrines, while the low caste Hindus tended not to use them. Few dry latrines existed in Satna. More than 75% of the households used the PF latrines, especially in Khandwa. The latrines generally were in disrepair, because more families did not receive either instruction or back-up latrine maintenance. Other apparent reasons for poor maintenance were limited water, illiteracy, limited knowledge of how the PF latrine works, poor construction, excreta adhering to the squatting pan, rain entering the leach pits through the squatting pan causing overflow of the pits contents, clogged outlets and Y-junctions, difficulty in emptying the pits, and collapsed brick drains. Children did not use the latrines in more than 50% of households were the latrines were used. Uncomfortable seats were the reason the children chose to defecate in the open. These findings led the author to recommend that the government adopt laws addressing sanitation in low-cost housing settlements, slums, and other areas. A PF latrine must be constructed for each new building. Dry or bucket latrines must be connected to sewers, if available. Leach pits must be constructed for converting latrines into PF latrines. There should be a ban on new dry or bucket latrines. The government should provide the local authorities the power to enforce these regulations. PF latrines should be free for the poor.

    This paper presents a model of situation awareness (SA) that emphasises that SA is necessarily built using a subset of available information. A technique (Quantitative Analysis of Situation Awareness - QASA), based around signal detection theory, has been developed from this model that provides separate measures of actual SA (ASA) and perceived SA (PSA), together with a feature unique to QASA, a measure of bias (information acceptance). These measures allow the exploration of the relationship between actual SA, perceived SA and information acceptance. QASA can also be used for the measurement of dynamic ASA, PSA and bias. Example studies are presented and full details of the implementation of the QASA technique are provided. Practitioner Summary: This paper presents a new model of situation awareness (SA) together with an associated tool (Quantitative Analysis of Situation Awareness - QASA) that employs signal detection theory to measure several aspects of SA, including actual and perceived SA and information acceptance. Full details are given of the implementation of the tool.

    2012-12-01

    Understanding how persons, situations, and behaviors contribute to behavioral consistency is a central goal for the science of behavior. The present study focused on dyadic social situations that were created by professional actors who enacted 4 social roles derived from interpersonal theory: dominant, submissive, agreeable, and quarrelsome. A total of 128 behavioral episodes from 32 target participants who each interacted for 5 min with 4 same-sex actors were videotaped. Several behaviors were coded from the videos, and stranger-ratings of targets' personality and behavior in the four different situations were also obtained based on those videos. The results provided novel evidence regarding the cross-situational consistency of different behaviors and allowed the following conclusions: (a) on average, targets were both rank-order and intraindividually consistent; (b) molar behaviors were more rank-order consistent than were micro-level behaviors; (c) interpersonal behavioral tendencies were evident in directly observed behavior, and (d) high Conscientiousness may facilitate interaction with quarrelsome partners.

    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.

    During the assembly of a product, it is vital that the partially-completed assembly be stable. To guarantee this, one must ensure that contacts among the parts and the fixtures are sufficient to stabilize the assembly. Thus, it would be desirable to have an efficient method for testing an assembly stability, and, if this is not possible, generating a set of additional fixture contact points, known as fixels, that will stabilize it. One can apply this method to the situation of safe handling of special nuclear material (SNM). To have these functionalities should help improve the safety and enhance the performance of special nuclear material (SNM) handling and storage operations, since some methods are needed for gripping objects in a stable manner. Also, one may need a way to find a pit-holding fixture inserted into containers. In this paper, the authors present a stability tool, which they call Stab Tool, which was developed to test the stability of objects grasped by robotic hands, objects placed in fixtures, or sets of objects piled randomly on top of one another. Stab Tool runs on top of a commercial software package, TELEGRIP, which is used for geometry modeling and motion creation. The successful development of the stability depends strongly on TELEGRIP`s ability to compute the distances between pairs of three-dimensional bodies in the simulated environment. The interbody distance computation tool takes advantage of the polyhedral representations of bodies used by TELEGRIP and of linear programming techniques to yield an efficient algorithm.

    Dwivedi, Anurag; Tebben, Dan

    2012-06-01

    The advent of cyber threats has created a need for a new network planning, design, architecture, operations, control, situational awareness, management, and maintenance paradigms. Primary considerations include the ability to assess cyber attack resiliency of the network, and rapidly detect, isolate, and operate during deliberate simultaneous attacks against the network nodes and links. Legacy network planning relied on automatic protection of a network in the event of a single fault or a very few simultaneous faults in mesh networks, but in the future it must be augmented to include improved network resiliency and vulnerability awareness to cyber attacks. Ability to design a resilient network requires the development of methods to define, and quantify the network resiliency to attacks, and to be able to develop new optimization strategies for maintaining operations in the midst of these newly emerging cyber threats. Ways to quantify resiliency, and its use in visualizing cyber vulnerability awareness and in identifying node or link criticality, are presented in the current work, as well as a methodology of differential network hardening based on the criticality profile of cyber network components.

    Full text: Medical cyclotron is a particle accelerator used in producing short lived radioisotopes such as 18 F, 11 C, 15 O, 13 N, 18 F-2 gas etc. Positron Emission Tomography (PET) is a nuclear imaging modality that has rapidly gained favour. 18 F-FDG is the most widely used radiopharmaceutical with a half-life of 109.8 min. Having more than five years experience in this field we face lots of emergency conditions in the medical cyclotron facility. On the basis of harm we have divided in to three categories i.e. Harm of (a) working personnel, (b) Equipment and (c) environment. Radioactive gas leak and Target foil rupture is considered as the major emergency situations during medical cyclotron operations because there is a potential of over exposure to the working personnel. Radiation protection survey of a self-shielded medical cyclotron installation was carried out during normal and emergency conditions. It is found that the induced activity in the target foil increases with its successive usages. Recommendations have also been made to reduce personal exposure while handling the radioactive gas leak and target foil rupture conditions

    Mental health is a serious problem in Latin America where many communities have been directly affected by armed conflict, communities in which large population groups have been displaced or have sought refuge. Research studies and epidemiological statistics are summarized to emphasize the psychosocial consequences of traumatic events associated with armed conflict. In addition to specific psychological disorders, other more generalized are considered such as fear, affliction, diseases, social disorder, violence and psychoactive substance consumption. Finally, the main points of a mental health plan for emergency situations are described which include the following: (1) preliminary diagnosis, (2) increase, decentralize and strengthen mental health public services, (3) psychosocial attention to the prevailing disorders--with emphasis on childhood problems, (4) initiate training and use of non-specialized personnel, and (5) identification of special needs requiring attention by psychologists and psychiatrists. Other aspects emphasized were community education, training, social communication, community organization, social participation, interinstitutional coordination, flexibility, sustainability, and specific actions in accordance with local needs.

    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.

  4. The situation of European power supply

    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.)

    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.

  7. The Educational Situation Quality Model: Recent Advances

    Doménech-Betoret, Fernando

    2018-01-01

    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.

    This paper presents the morally controversial phenomenon of prostitution. As the basis for contemplating the prostitution issue the most important is revealing and understanding its primitive ethical root. For understanding its "soul", its essence, also important is comprehending sexual, "elementary thoughts" of mankind, through the relationship between prostitution and religious, social, political and spiritual life, and its nature as a reflection of the sexual-ethical concepts in different epochs and nations. We emphasize the connection between prostitution and psychiatry. Placing a special focus on importance of personality for deciding to become a prostitute, and by pulling it through a moral prism we define prostitution as a new medical situation. In favor of that, we stress the importance of the presence, position and role of psychiatrists within an indispensable multidisciplinary team, which is complementary despite its heterogeneousness, synergistically and simultaneously dealing with psychological, physical and social health-problems of women engaged in prostitution. We propose peer education as a way of promoting healthy and safer behaviors among the subculture of prostitutes, where we see another important role of psychiatrists in selecting/recruiting, training and motivating peer educators among them.

    Full Text Available We explore the ways in which animate objects can be used to cue actions as part of coaching in Activities of Daily Living (ADL. In this case, changing the appearance or behavior of a physical object is intended to cue actions which are appropriate for a given context. The context is defined by the intention of the users, the state of the objects and the tasks for which these objects can be used. We present initial design prototypes and simple user trials which explore the impact of different cues on activity. It is shown that raising the handle of a jug, for example, not only cues the act of picking up the jug but also encourages use of the hand adjacent to the handle; that combinations of lights (on the objects and auditory cues influence activity through reducing uncertainty; and that cueing can challenge pre-learned action sequences. We interpret these results in terms of the idea that the animate objects can be used to create affording situations, and discuss implications of this work to support relearning of ADL following brain damage or injury, such as might arise following a stroke.

  10. The present situation of echinococcoses in Mongolia.

    This review presents the historical and current situation of echinococcoses in Mongolia. Since the collapse of the Soviet Union in 1991, Mongolia's health surveillance infrastructure has been very poor, especially as it pertains to chronic diseases, including neglected zoonotic diseases (NZDs). Although there is anecdotal evidence of people dying from hepatic disease due to infection with the larval stage of Echinococcus spp., there are very few published reports. All confirmed cases of echinococcoses in Mongolia are from hospitals located in the capital city of Ulaanbaatar. Cases of cystic echinococcosis (CE), caused by either Echinococcus granulosus sensu stricto or Echinococcus canadensis are believed to be relatively common throughout Mongolia. In contrast, cases of alveolar echinococcosis (AE), caused by Echinococcus multilocularis, are believed to be rare. Recent wild-animal surveys have revealed that wolves (Canis lupus) are the major definitive hosts of E. canadensis, whereas both wolves and red foxes (Vulpes vulpes) are the primary definitive hosts of E. multilocularis. Although wild-animal surveys have begun to elucidate the transmission of Echinococcus spp. in Mongolia, there have yet to be large-scale studies conducted in domestic dogs and livestock. Therefore, further epidemiological studies, in addition to education-based control campaigns, are needed to help combat this NZD.

    This paper summarizes the situation pertinent to treatment via lipoprotein apheresis in the federal state of Saxony, Germany in 2010. In total, 119 predominately male patients were treated in 10 centers; the majority of the patients was older than the mean age of the general population. Several risk factors were present, particularly a familial predisposition and hypertension. All patients had experienced cardiovascular events and the majority was taking statins. Patient data from the University Hospital Carl Gustav Carus in Dresden concurred with data derived from patients treated at nephrological practices. In the mean, patients attended the centers for about 6 years, the majority weekly. LDL cholesterol concentrations prior to apheresis were clearly higher than target levels; apheresis sessions decreased LDL cholesterol by 69%. Lipoprotein(a) levels could be measured in 75 patients and were effectively reduced by lipoprotein apheresis. In Saxony, 29 patients per 1 million inhabitants received lipoprotein apheresis, which is higher than the proportion of patients treated in Germany as a whole. The need for this extracorporeal treatment seems to be much greater than its current utilization. Among the patients only one homozygous patient with familial hypercholesterolemia was observed. Physicians should be actively informed about this therapeutic possibility to reduce the cardiovascular risk efficiently. The introduction of new drugs may alter the position of lipoprotein apheresis within the therapeutic spectrum. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    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.

    2018-03-01

    Full Text Available 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.

  14. Regularizations: different recipes for identical situations

    2004-03-01

    We present a discussion where the choice of the regularization procedure and the routing for the internal lines momenta are put at the same level of arbitrariness in the analysis of Ward identities involving simple and well-known problems in QFT. They are the complex self-interacting scalar field and two simple models where the SVV and AVV process are pertinent. We show that, in all these problems, the conditions to symmetry relations preservation are put in terms of the same combination of divergent Feynman integrals, which are evaluated in the context of a very general calculational strategy, concerning the manipulations and calculations involving divergences. Within the adopted strategy, all the arbitrariness intrinsic to the problem are still maintained in the final results and, consequently, a perfect map can be obtained with the corresponding results of the traditional regularization techniques. We show that, when we require an universal interpretation for the arbitrariness involved, in order to get consistency with all stated physical constraints, a strong condition is imposed for regularizations which automatically eliminates the ambiguities associated to the routing of the internal lines momenta of loops. The conclusion is clean and sound: the association between ambiguities and unavoidable symmetry violations in Ward identities cannot be maintained if an unique recipe is required for identical situations in the evaluation of divergent physical amplitudes.

    Much progress has been made in attaining high confinement regimes in magnetic confinement devices. These operating modes tend to be transient, however, due to the onset of MHD instabilities, and their stabilization is critical for improved performance at steady state. This report describes the Feedback Stabilization Initiative (FSI), a broad-based, multi-institutional effort to develop and implement methods for raising the achievable plasma betas through active MHD feedback stabilization. A key element in this proposed effort is the Feedback Stabilization Experiment (FSX), a medium-sized, national facility that would be specifically dedicated to demonstrating beta improvement in reactor relevant plasmas by using a variety of MHD feedback stabilization schemes

    Minimally invasive surgery has gained significantly in importance over the last decade due to the numerous advantages on patient-side. The surgeon has to adapt special operation-techniques and deal with difficulties like the complex hand-eye coordination, limited field of view and restricted mobility. To alleviate these constraints we propose to enhance the surgeon's capabilities by providing a context-aware assistance using augmented reality (AR) techniques. In order to generate a context-aware assistance it is necessary to recognize the current state of the intervention using intraoperatively gained sensor data and a model of the surgical intervention. In this paper we present the recognition of risk situations, the system warns the surgeon if an instrument gets too close to a risk structure. The context-aware assistance system starts with an image-based analysis to retrieve information from the endoscopic images. This information is classified and a semantic description is generated. The description is used to recognize the current state and launch an appropriate AR visualization. In detail we present an automatic vision-based instrument tracking to obtain the positions of the instruments. Situation recognition is performed using a knowledge representation based on a description logic system. Two augmented reality visualization programs are realized to warn the surgeon if a risk situation occurs.

    The latest results of the ATLAS and CMS experiments point to a preferred narrow Higgs mass range (m_h \\simeq 124 - 126 GeV) in which the effective potential of the Standard Model (SM) develops a vacuum instability at a scale 10^{9} -10^{11} GeV, with the precise scale depending on the precise value of the top quark mass and the strong coupling constant. Motivated by this experimental situation, we present here a detailed investigation about the stability of the SM^{++} vacuum, which is characterized by a simple extension of the SM obtained by adding to the scalar sector a complex SU(2) singlet that has the quantum numbers of the right-handed neutrino, H", and to the gauge sector an U(1) that is broken by the vacuum expectation value of H". We derive the complete set of renormalization group equations at one loop. We then pursue a numerical study of the system to determine the triviality and vacuum stability bounds, using a scan of 10^4 random set of points to fix the initial conditions. We show that, if there...

    Full Text Available From March 7, 1995 to April 16, 1995 du ring the rainy season the utilisation of edible snails was investigated in Indonesia. To assess the current situation, the focus was put to answer the following questions : - Is it feasible under the present circumstances to domesticate these snails with the aim to conserve the natural resources ? - Could any individual or private initiative be enhanced or utilized ? - Would local disadvantaged groups (traditional animal farmers, women oryouths be benefitted through domestication of these snails ? - Is there any existing private organisation or NGO, which already gathers and trades the snails or would be interested to do this in the future ? Snails gatherers, -dealers and -farmers were visited and interviewed on the following topics using standardised questionnaires : Spreading and ecology ways of marketing, consumption habits, breeding and rearing. Diotopes were also visited and investigated. Results Spreading and ecology : Achatina fulica, Pomacea canaliculata, Pila ampullacea and Bellamia javanica are eaten. The snails can be found ail overJava. Ways of marketing : The snails gathered in the biotope are either marketed directly or through various marketing paths. A. fulica is exported in large quantifies. The population is therefore endangered. Consumption habits : Snails are not eaten regularly. Snail meat is known to be healthy. The consumption depends on the consumer's ethnie background. Breeding and rearing experience : with simple breeding systems for A. fulica and P. canaliculata are seldom found. The breeding of P. canaliculata is forbidden in Indonesia. There is no interest in breeding P. ampullacea or B. javanica. The breeding of A. fulica can ben-efit disadvantaged groups financially and help to conserving the natural snail population.

  20. Treemap Visualizations for Space Situational Awareness

    Ianni, J.; Gorrell, Z.

    Making sense of massive data sets is a problem for many military domains including space. With unwieldy big data sets used for space situational awareness (SSA), important trends and outliers may not be easy to spot especially not at-a-glance. One method being explored to visualize SSA data sets is called treemapping. Treemaps fill screen space with nested rectangles (tiles) of various sizes and colors to represent multiple dimensions of hierarchical data sets. By mapping these dimensions effectively with a tiling algorithm that maintains an appropriate aspect ratio, patterns can emerge that often would have gone unnoticed. The ability to interactively perform range filtering (in our case with sliders) and object drill-downs (hyperlinking the tiles) make this technology powerful for in-depth analyses in addition to at-a-glance awareness. For one SSA analysis, the tiles could represent satellites that are grouped by country, sized by apogee, and colored/shaded by the launch date. Filter sliders could allow apogee range or launch dates to be narrowed for better resolution of a smaller data set. The application of this technology for the Joint Space Operations Center (JSpOC) Mission System (JMS) is being explored on a DARPA Small Business Innovative Research (SBIR) effort as a plug-in to the existing User-Defined Operational Picture (UDOP). In addition, visualization of DARPA OrbitOutlook small telescope data will be demonstrated. This research will investigate what SSA analyses are best served by treemaps, the best tiling algorithms for these problems, and how the treemaps should be integrated into the existing JMS UDOP workflow. Finally, we introduce a variation of treemaps that help leaders allocate their time to tasks based on importance and urgency.

  1. Nuclear data. Situation and future projects

    Nuclear power provides the major part of the electricity generation in France, using a system of highly developed Pressurized Water Reactors. Electricite de France, which is responsible for the exploitation of this system, is concerned to ensure the continuity of the expertise and facilities which provide relevant basic scientific information contributing to the efficient exploitation of the system and, in particular, the continuity of the means for providing relevant nuclear data. The nuclear data requirements for the exploitation of the existing nuclear power system have been largely met. However, there remain some needs, in particular in the field of reactor neutronics. Furthermore if one considers the future (for example, the next 10 years) it is not certain that will be possible to meet the needs which are expected to arise. The review, commissioned on behalf of EDF, about the current status and future expectations for work in this field, has shown certain tendencies in the international situation. In particular one notes a general reduction in the effort both in Western Europe and the United States. This negative tendency can perhaps be explained by the almost general reduction world-wide in new nuclear power developments. However, unresolved problems remain, such as the development of methods for reducing the stocks of plutonium and the incineration and storage of a nuclear waste of long duration. In addition improvements in the accuracy of nuclear data could result in non-negligible economic benefits in the exploitation of the existing nuclear facilities. For these very important reasons it is desirable to reverse the present trend. (author). 2 annexes

    For a very long time China has been the most populous country in the world. Throughout the last 15-16 years China has achieved great success in checking the excessively rapid growth of its population. However, due to historical reasons as well as current changes, China is still facing a serious situation. As a result of historical evolution, a great number of contradictions exist in China between population on the 1 hand and arable land, food, natural resources, the environment, employment, education, and support of the aged on the other hand. Per capita arable land is now only about .1 hectare. Restricted by the area of arable land, the food supply in China has always been a source of tension. People are reclaiming land on hills and from lakes in ways that are not good for the environment. With rapid population growth, large numbers of young people are reaching working age every year. The ultimate goal of modernization is to promote the well-being of the people. Although the achievements of economic development have been remarkable, the level of goods per person remains low. This has made people realize that population growth must be controlled. The main causes of the rapid fertility decline are 1) socioeconomic development, 2) state guidance, and 3) a strong government policy. Beginning in 1979 in China, the focal point of work has been shifted to economic construction. China's strategic goal of population control is to attain the stationary state through rapid fertility decline. Prospects for the 21st century include 1) an aging population, 2) a more abundant labor force, 3) the further development of cultural and educational undertakings, 4) rapid urbanization, and 5) environmental pollution and resource shortages.

  3. Understanding extraverts' enjoyment of social situations: the importance of pleasantness.

    2001-08-01

    Extraversion is a broad, multifaceted trait, yet researchers are still unsure of its defining characteristics. One possibility is that the essential feature of extraversion is the tendency to enjoy social situations. An alternative possibility is that extraversion represents sensitivity to rewards and the tendency to experience pleasant affect. In three studies, participants rated situations that varied on two dimensions: (a) whether they were social or nonsocial and (b) whether they were very pleasant, moderately pleasant, moderately unpleasant, or very unpleasant. Extraverts only rated social situations more positively than introverts did when the situations were pleasant, and extraverts also rated nonsocial situations more positively than introverts did if the situations were pleasant. Thus, the pleasantness of situations was more important than whether they were social or nonsocial in determining extraverts' and introverts' enjoyment.

    Stabilization of enzymes is a key factor when using biocatalysis in practice. Each enzyme stability depends both on the structure of its molecule and on the effect of various environmental factors, thus, one of the methods of the enzyme stability preservation is the formation of optimal macromedium. Thus, water structure and enzyme hydration change in the presence of solvable additives that affects its stability and catalytic properties. The paper deals with a new method of stabilization of human thrombin developed by the authors. It is proposed to use some known organic-ligands which have ion group and different nonpolar hydrophobic groups instead of traditional additives (salts, aminoacids, polyols, polyethylene glycols etc.). Thrombin stabilization proceeds in the conditions something changed compared with traditional ones. Processes of thrombin stabilization by the above compound have been investigated, enzyme stability at different temperatures and long-term storage of diluted solutions of the preparation in different conditions have been studied. It has been established that rosselin and orange II are the most efficient ligands. Optimal finite concentrations of stabilizing agents make approximately 0.0012-0.0014 M which are rather low in the system thrombin-ligand. It has been found that diluted solutions of thrombin are more stable, than concentrated ones. In the latter case the process of autolysis is included that affects negatively the catalytic effect of the enzyme, as far as there occurs the change of thrombin molecule structure, especially of thrombin beta-chain sections, evoking conformational changes of some sites of its active centre. The experiments directed to increasing thrombin intensity in the presence of organic ligands rosselin and orange II are discussed in details. Special attention is given to autolytic method of thrombin inactivation. It is admitted on the basis of already obtained data that thrombin binding with organic ligands proceeds

    Full Text Available Rabies is a dangerous infections disease which is highly fatal and zoonotic. The disease occurs in many countries of the world and in Iran, rabies is endemic and a major public health Problem. Most warm blooded animals are susceptible to rabies. It is transmitted by the bite of an infected animal to humans and other animals. The saliva of the sufferers is a rich source of rabies virus. Rabies is not seen in countries such as Scandinavia, Britain, Ireland, Scotland, Australia and New Zealand which is related to their geographical situation and being surrounded by water. But in countries like the United States of America, Canada, Europe and Iran the rabies is endemic. Dogs, wild carnivores especially wolves and foxes are the main transmitters of the disease. Rabies has been known approximately from the year 2300 BC with the dog considered as the main vector. Scientists like Avicenna and Sayyed Esmail Jorjani have described rabies. Louis Pasteur presented antirabies treatment and vaccinations in 1885. The Pasteur institute of Iran opened in 1920 and today there are more than 300 antirabies treatment centers in the country involved with the treatment rabies. More than 100000 persons each year in Iran are treated for rabies due to being bitten by animals especially dogs suspected of having rabies. According to the report of the Pasteur institute of Iran, 421 Positive cases of rabies of which 3 were human cases where recorded in the year 2001. These figures for 2002 to 2004 were 356 positive cases with 6 human cases, 314 positive cares with 10 human cases and 325 positive cases with 5 human cases respectively. On average, 6 human cases of rabies were recorded each year with all leading to death. Considering the increasing trend of animal bites and the number of animals and humans affected by rabies the responsible authorities including the National Veterinary Organization, Ministry of health, municipalities, Ministry of Interior and … must present

However, in recent years, Mexican public politics are looking after the improvement of women quality of life, particularly in the last ten years. Implementing governmental actions to prevent different ways of discrimination towards women, looking for gender equity in the Mexican society. In particular, Tepexilotla is a community of the Mexican state of Veracruz, that despite of being so small village, is actively its development. Regarding gender, after four years of continuous work in the community, there are initiating changes in social and familiar relationships, because is getting each time more involved in the economical activities, such as agroecotourism. Specifically, these have been observed on relation to their participation in the agro-ecoturistic activity that has started to be a resource of employment and development in the town. As far as Tepexilotla has been received the training from “Colegio de Postgraduados” to design rural touristic routes that have encouraged this activity en this community (between other active-research and projects in that microregion. Between these projects, Rural turism emerged from a integral participative diagnostic (DIP to detect potential projects of the microregion, where the people from the community raise their interest to learn “touristic guides” habilities, because they were interested on showing prehispanic ruins as well as caves and ecological areas, that emerged as potential resources for development. In this way, the project borned to achieve agro-ecoturistic activities that help to potentialize the agricultural, ecological and touristic activities, with the gender perspective view, (considering both men and women.

  9. Children and the global tuberculosis situation.

    Enarson, Donald A

    2004-01-01

    The current global strategy for control of tuberculosis, Directly Observed Treatment, Short-course (DOTS) focuses, as a priority, on the management of patients with sputum smear positive tuberculosis. As tuberculosis in children is rarely sputum smear positive, this has led many to believe that children are not important in tuberculosis control. This is a misconception. The ultimate goal of tuberculosis services should be the eradication of Mycobacterium tuberculosis. To date, only diseases for which effective vaccines are available have been eradicated. Vaccination aims to protect the population (and especially vulnerable groups, such as children) from the disease against which it is applied. Presently, there is no vaccine able to prevent infection with Mycobacterium tuberculosis. Protection against infection must be achieved in other ways. Thus, early identification and successful treatment of the most infectious cases of tuberculosis has become the focus of attempts and is presently the most effective means to protect children from infection with M. tuberculosis. This is the theory; does it really work? Evidence put forward to support this position has come primarily from industrialised countries where tuberculous infection was already on the decline before any substantial public health activities had been instituted. What of the situation in low income countries where the highest proportion of the tuberculosis patients live at the present time? There is very little evidence available to address this question. The most convincing information published to date comes from the Beijing Municipality of China where the DOTS strategy has been implemented since 1978. Progressive expansion of the strategy occurred over the first five years after which a very high proportion of all tuberculosis patients were managed by this means. The major impact was to progressively and rapidly reduce the prevalence of tuberculosis in the community. The incidence was only more slowly

    Operators in nuclear power plants have to acquire information from human system interfaces (HSIs) and the environment in order to create, update, and confirm their understanding of a plant state, or situation awareness, because failures of situation assessment may result in wrong decisions for process control and finally errors of commission in nuclear power plants. Quantitative or prescriptive models to predict operator's situation assessment in a situation, the results of situation assessment, provide many benefits such as HSI design solutions, human performance data, and human reliability. Unfortunately, a few computational situation assessment models for NPP operators have been proposed and those insufficiently embed human cognitive characteristics. Thus we proposed a new computational situation assessment model of nuclear power plant operators. The proposed model incorporating significant cognitive factors uses a Bayesian belief network (BBN) as model architecture. It is believed that communication between nuclear power plant operators affects operators' situation assessment and its result, situation awareness. We tried to verify that the proposed model represent the effects of communication on situation assessment. As the result, the proposed model succeeded in representing the operators' behavior and this paper shows the details

    The primary aim of this study was to identify coping strategies used to manage problematic tinnitus situations. A secondary aim was to determine whether different approaches were related to the level of tinnitus distress, anxiety, depression, and insomnia experienced. A cross-sectional survey design was implemented. The study sample was adults interested in undertaking an Internet-based intervention for tinnitus. Self-reported measures assessed the level of tinnitus distress, depression, anxiety, and insomnia. An open-ended question was used to obtain information about how problematic tinnitus situations were dealt with. Responses were investigated using qualitative content analysis to identify problematic situations. Further data analysis comprised of both qualitative and quantitative methods. There were 240 participants (137 males, 103 females), with an average age of 48.16 years (SD: 22.70). Qualitative content analysis identified eight problematic tinnitus situations. Participants had either habituated to their tinnitus (7.9%), used active (63.3%), or passive (28.8%) coping styles to manage these situations. Those who had habituated to tinnitus or used active coping strategies had lower levels of tinnitus distress, anxiety, and depression. The main problematic tinnitus situations for this cohort were identified. Both active and passive coping styles were applied to approach these situations. The coping strategies used most frequently and utilised in the widest range of problematic situations were using sound enrichment and diverting attention. Implications for Rehabilitation The main problematic tinnitus situations for this group of participants were identified. Overall, a limited range of strategies were used to deal with individual problematic situations. The use of sound enrichment and diverting attention was applied in the widest range of problematic situations. The use of both active and passive coping styles was evident to approach these situations. The

    The nursing student requires opportunities to learn within authentic contexts so as to enable safe and competent practice. One strategy to facilitate such learning is the creation of learning situations. A lack of studies on the learning situation in nursing and other health care fields has resulted in insufficient knowledge of the characteristics of the learning situation, its antecedents, and consequences. Nurse educators need to have comprehensive and practical knowledge of the definition and characteristics of the learning situation so as to enable their students to achieve enhanced learning outcomes. The aim of this study was to clarify the concept of the learning situation as it relates to the education of nurses and improve understanding of its characteristics, antecedents, and consequences. The Bonis method of concept analysis, as derived from the Rodgers' evolutionary method, provided the framework for analysis. Data collection and analysis were undertaken in two phases: "interdisciplinary" and "intra-disciplinary." The data source was a search of the literature, encompassing nursing and allied health care professions, published from 1975 to 2016. No agreement on the conceptual phenomenon was discovered in the international literature. The concept of a learning situation was used generally in two ways and thus classified into the themes of: "formal/informal learning situation" and "biologic/nonbiologic learning situation." Antecedents to the creation of a learning situation included personal and environmental factors. The characteristics of a learning situation were described in terms of being complex, dynamic, and offering potential and effective learning opportunities. Consequences of the learning situation included enhancement of the students' learning, professionalization, and socialization into the professional role. The nurse educator, when considering the application of the concept of a learning situation in their educational planning, must

Elle est en effet marquée par un triple éclatement : le double éclatement interne entre théorie et empirie et entre écoles rivales et l’éclatement externe entre sociologie, histoire, critique littéraire et philosophie – auquel on pourrait ajouter un quatrième qui les recoupe et les redouble : l’absence de la sociologie des grands débats théoriques et politiques actuels. Il est donc urgent d’identifier le dénominateur commun à tous les courants de pensée évoqués dans l’article, de manière à pouvoir à la fois organiser une transmission raisonnée des acquis de la réflexivité moderne, et opposer une légitimité théorique alternative suffisamment puissante à la légitimité impérialiste de la science économique.Present situation of sociologyAlthough worldwide we can account for more and more sociologists, sociology is revealing in fact to be more and more uncertain of its identity, meaning and legitimacy.

It is then urgent to identify the common denominator to all these currents of thought mentioned in this paper, so that it can organize a reasoned knowledge transfer of modern reflexivity, powerful enough to oppose an alternate legitimate theory to economics’ legitimate imperialism.La situación actual de la sociologíaAunque cada vez hay más sociólogos la sociología es cada vez más incierta por que respecta a su propia identidad,  a su propio sentido y a su legitimidad

    Cancer is a worldwide problem. According to the World Health Organization (WHO), 12.4 million of new cancer cases and 7.6 million of deaths have been registered worldwide, during 2012-2013. The trend is still rising. The International Agency for Research on Cancer (IARC), report that by 2030 there will be between 20 and 25 million cases of cancer, and 13 to 16 million of annual deaths due to cancer. Cancer remains the second cause of deaths in developed countries after cardiovascular diseases. This situation is beginning to be observed in emerging countries. Three main factors are advanced to explain the development of cancer: The population aging, the adoption of western lifestyle (bad eating habits, physical inactivity, obesity ...) and tobacco. In our country, the number of new cases of cancers per year is estimated to be 10300 (5900 for males and 4400 for females). The crude incidence rate for all localities is about 117.9 / 100 000, for male and 87.6 / 100,000, for females. We list the main achievements registered until now: The first program planed for the cancer was performed in the city of Jerba, in August 1995. The second cancer plan was done in 1995-1998, in Carthage. In December 1996, a cancer plan was established for the period between 2006 and 2010. About the cancer registration: three population-based cancer registries were set up (in the North, Sfax and Sousse). Regarding infrastructure, we count in the public sector: The Salah Azaiez Instiute of cancer (SAI), in Tunis, the two cancer centers (in Sousse and Sfax), the four units of oncological medicine (Jendouba, Gafsa, Gabes, Kairouan). Projects concerning radio and chemotherapy units are currently in progress, in Ariana, and two units of oncological medicine, in Beja and Monastir. In the private sector, three clinics are mentioned: 02 clinics are already active, the third is under construction and 04 clinics for radiotherapy (02 in Tunis and 02 in Sfax).

  20. Situated Cognition, Ecological Perception, and Synergetics: a Novel Perspective for Cognitive Psychology?

    Science.gov (United States)

    Tschacher, Wolfgang; Dauwalder, Jean-Pierre

    Cognitive psychology encounters various problems, such as the problem of intentionality, the symbol grounding and representation problems, and the problem of cognitive stability. These problems originate from the mind-body dichotomy; thus, foundational philosophical topics have quite concrete consequences for cognitive psychology and autonomous agents design. We argue that cognitive theory and modeling must account for stability, autonomy or completeness (i.e., should not rely on homunculi), and optimality. A synergetic model is proposed that has the desired properties: Cognition rests upon perception-action cycles. Cognition is viewed as ecological, i.e. it is situated by environmental affordances (valences) which signal energy resources. These cycles have an built-in optimality function because they maximize entropy production by dissipating affordances.

    To predict changes of situation awareness (SA) for pilot operating with different display interfaces and tasks, a qualitative analysis and quantitative calculation joint SA model was proposed. Based on the situational awareness model according to the attention allocation built previously, the pilot cognitive process for the situation elements was analyzed according to the ACT-R (Adaptive Control of Thought, Rational) theory, which explained how the SA was produced. To verify the validity of this model, 28 subjects performed an instrument supervision task under different experiment conditions. Situation Awareness Global Assessment Technique (SAGAT), 10-dimensional Situational Awareness Rating Technique (10-D SART), performance measure and eye movement measure were adopted for evaluating SAs under different conditions. Statistical analysis demonstrated that the changing trend of SA calculated by this model was highly correlated with the experimental results. Therefore the situational awareness model can provide a reference for designing new cockpit display interfaces and help reducing human errors.

    Full Text Available The article analyzes the concept of "legally significant situation." Discusses the classification of situations from the point of view of criminology and forensic psychological assessment. Highlights the main features of this type of situations from the point of view of psychology: the nature of conflict, involving the participation of third parties, as well as the presence of certain psychological consequences. This allows to describe the Genesis of certain situations, and to identify the States generated at each stage. It is also noted that the specificity of the legally significant cases involving minors is its group nature (the child as part of a family or other group. Thus, it is possible to give the following definition of a legally relevant situation within legal psychology, children and adolescents: a situation involving minors, subjects who are in relationships, conflict is caused by interactions in the legal context, which leads not only to legally relevant, but also to the psychological consequences for its participants.

  4. A situational approach to the measurement of safety culture

    1997-01-01

    Values and social norms are the main target of most approaches to the study of safety culture and many existing survey methodologies directly ask for these norms and values. However, a number of considerations point to the dangers of limiting the evaluation of safety culture to the analysis of these responses. Therefore the necessity is stressed to also consider how actual situations activate norms and behaviours. This relates to the fact that in any given situation both aspects of the appraisal of reality are present: the objective definition of the situation and its personal evaluation. The latter not only reflects the ''official'' norms and values but also ''basic underlying assumptions''. The situational approach introduced in this paper confronts people with situations which contain a dilemma with conflicting social norms and where various costs and benefits are associated with different types of behaviour. In addition, the prerequisites and limitations of the situational approach are discussed. (author). 9 refs, 1 fig

    Situation awareness describes an individual's perception, comprehension and subsequent projection of what is going on in the environment around them. The concept of situation awareness sits within the group of non-technical skills that include teamwork, communication and managing hierarchical lines of communication. The importance of non-technical skills has been recognised in safety-critical industries such as aviation, the military, nuclear, and oil and gas. However, health care has been slow to embrace the role of non-technical skills such as situation awareness in improving outcomes and minimising the risk of error. This article explores the concept of situation awareness and the cognitive processes involved in maintaining it. In addition, factors that lead to a loss of situation awareness and strategies to improve situation awareness are discussed.

    Full Text Available OBJECTIVE: This study modeled win and lose trials in a simple gambling task to examine the effect of entire win-lose situations (WIN, LOSS, or TIE on single win/lose trials and related neural underpinnings. METHODS: The behavior responses and brain activities of 17 participants were recorded by an MRI scanner while they performed a gambling task. Different conditions were compared to determine the effect of the task on the behavior and brain activity of the participants. Correlations between brain activity and behavior were calculated to support the imaging results. RESULTS: In win trials, LOSS caused less intense posterior cingulate activity than TIE. In lose trials, LOSS caused more intense activity in the right superior temporal gyrus, bilateral superior frontal gyrus, bilateral anterior cingulate, bilateral insula cortex, and left orbitofrontal cortex than WIN and TIE. CONCLUSIONS: The experiences of the participants in win trials showed great similarity among different win-lose situations. However, the brain activity and behavior responses of the participants in lose trials indicated that they experienced stronger negative emotion in LOSS. The participants also showed an increased desire to win in LOSS than in WIN or TIE conditions.

    Eighty percent of medical error are attributed to human factors. Human factors experts suggest the least explored factor in patient errors is attention, specifically, situation awareness. The purpose of this article was to analyze the concept of situation awareness using a hybrid concept analysis. The experience of situation awareness among nurses was elicited during the fieldwork phase through semistructured interviews. Content and relational analyses yielded 9 themes: perception, comprehension, projection, knowledge and expertise, cognitive overload, interruption management, task management, instantaneous learning, and cognitive stacking. A conceptual definition of situation awareness emerged along with recommendations for application in nursing.

    Full Text Available Current mobile devices allow the execution of sophisticated applications with the capacity for identifying the user situation, which can be helpful in treatments of mental disorders. In this paper, we present SituMan, a solution that provides situation awareness to MoodBuster, an ecological momentary assessment and intervention mobile application used to request self-assessments from patients in depression treatments. SituMan has a fuzzy inference engine to identify patient situations using context data gathered from the sensors embedded in mobile devices. Situations are specified jointly by the patient and mental health professional, and they can represent the patient’s daily routine (e.g., “studying”, “at work”, “working out”. MoodBuster requests mental status self-assessments from patients at adequate moments using situation awareness. In addition, SituMan saves and displays patient situations in a summary, delivering them for consultation by mental health professionals. A first experimental evaluation was performed to assess the user satisfaction with the approaches to define and identify situations. This experiment showed that SituMan was well evaluated in both criteria. A second experiment was performed to assess the accuracy of the fuzzy engine to infer situations. Results from the second experiment showed that the fuzzy inference engine has a good accuracy to identify situations.

    People presumably choose and create their daily environments according to their personality. Prior research shows that, for example, more extraverted people engage more often in social situations, and more conscientious people engage more often in work-related activities compared with less extraverted or less conscientious people, respectively. The current study examined such personality-situation transactions in people's daily life. Based on the assumption that older people know themselves and their personality better than younger people, we investigated whether momentary and proximate personality-situation associations (i.e., changing from 1 type of situation into another) increase with older age. Three-hundred and 78 people aged 14 to 82 years described their Big Five traits and took part in a 3-week experience-sampling phase. Using mobile-phone based assessments in daily life, participants reported on average 55 times on their momentary situation. Multilevel modeling results showed that personality-situation associations varied with the age of participants. Some of the "established" personality-situation associations, such as for extraversion and time spent with friends or conscientiousness and time spent with work activities, were only observed in adolescence and young adulthood. In contrast, other personality-situation associations appeared only in late adulthood, such as for openness and time spent with friends. Yet most personality-situation associations did not vary significantly with people's age. In addition, personality traits predicted maintaining or entering personality-congruent situations. The latter results point to the active role of personality in shaping one's environment. The findings imply that some personality-situation transactions may be largely similarly across the life span.

    Gorban, Igor I

    2017-01-01

    This monograph investigates violations of statistical stability of physical events, variables, and processes and develops a new physical-mathematical theory taking into consideration such violations – the theory of hyper-random phenomena. There are five parts. The first describes the phenomenon of statistical stability and its features, and develops methods for detecting violations of statistical stability, in particular when data is limited. The second part presents several examples of real processes of different physical nature and demonstrates the violation of statistical stability over broad observation intervals. The third part outlines the mathematical foundations of the theory of hyper-random phenomena, while the fourth develops the foundations of the mathematical analysis of divergent and many-valued functions.

    We propose that the domain general process of categorization contributes to the perception of stress. When a situation contains features associated with stressful experiences, it is categorized as stressful. From the perspective of situated cognition, the features used to categorize experiences as stressful are the features typically true of stressful situations. To test this hypothesis, we asked participants to evaluate the perceived stress of 572 imagined situations, and to also evaluate each situation for how much it possessed 19 features potentially associated with stressful situations and their processing (e.g., self-threat, familiarity, visual imagery, outcome certainty). Following variable reduction through factor analysis, a core set of 8 features associated with stressful situations—expectation violation, self-threat, coping efficacy, bodily experience, arousal, negative valence, positive valence, and perseveration—all loaded on a single Core Stress Features factor. In a multilevel model, this factor and an Imagery factor explained 88% of the variance in judgments of perceived stress, with significant random effects reflecting differences in how individual participants categorized stress. These results support the hypothesis that people categorize situations as stressful to the extent that typical features of stressful situations are present. To our knowledge, this is the first attempt to establish a comprehensive set of features that predicts perceived stress. PMID:27288834
