Speaking rate adjustment across changes in talker  

NASA Astrophysics Data System (ADS)

Individuals vary their speaking rate, and listeners use the speaking rate of precursor sentences to adjust for these changes [Kidd (1989)]. Recent work has suggested that speaking rate adjustment may not always be limited to speech from a single talker (Sawusch and Newman, 2000). When a talker change occurs in the midst of a vowel, the durations of both portions of the vowel influence perception of the rate-based contrast. In the present experiments, we examined the effect of talker change on rate normalization for precursor phrases. A male talker produced the sentence, I heard him say the word-at one of three different speaking rates. A female talker then produced a nonword containing a duration-based contrast. We examined whether the male talker's speaking rate would influence perception of the female talker's speech. The results were somewhat surprising. The speaking rate of the first talker did influence perception of the contrast in the second talker. However, the effect was a U-shaped function of speaking rate, rather than the linear function typically demonstrated in the single-voice condition. Several follow-up studies replicated this basic pattern. Implications of this finding for studies of rate normalization will be discussed.

Children and adults integrate talker and verb information in online processing.  

PubMed

Children seem able to efficiently interpret a variety of linguistic cues during speech comprehension, yet have difficulty interpreting sources of nonlinguistic and paralinguistic information that accompany speech. The current study asked whether (paralinguistic) voice-activated role knowledge is rapidly interpreted in coordination with a linguistic cue (a sentential action) during speech comprehension in an eye-tracked sentence comprehension task with children (ages 3-10 years) and college-aged adults. Participants were initially familiarized with 2 talkers who identified their respective roles (e.g., PRINCESS and PIRATE) before hearing a previously introduced talker name an action and object ("I want to hold the sword," in the pirate's voice). As the sentence was spoken, eye movements were recorded to 4 objects that varied in relationship to the sentential talker and action (target: SWORD, talker-related: SHIP, action-related: WAND, and unrelated: CARRIAGE). The task was to select the named image. Even young child listeners rapidly combined inferences about talker identity with the action, allowing them to fixate on the target before it was mentioned, although there were developmental and vocabulary differences on this task. Results suggest that children, like adults, store real-world knowledge of a talker's role and actively use this information to interpret speech. PMID:24611671

Neural Bases of Talker Normalization  

Microsoft Academic Search

To recognize phonemes across variation in talkers, listeners can use information about vocal characteristics, a process referred to as talker normalization. The present study investigates the cortical mechanisms underlying talker normalization using fMRI. Listeners recognized target words presented in either a spoken list produced by a single talker or a mix of different talkers. It was found that both conditions

Do listeners perceive coarticulatory differences for normal talkers and neurologically impaired talkers?  

NASA Astrophysics Data System (ADS)

Speech production studies suggest that the extent of coarticulation varies across talkers. The extent of coarticulation may even vary for repetitions of the same utterance produced by a single talker. Thus, an utterance or talker could be characterized by an average degree of coarticulation, a high degree of coarticulation, or a low degree of coarticulation. The perceptual consequences, if any, of this coarticulatory variability are not well understood, particularly for individuals with speech motor control disorders. The current study examined whether the listeners' speed and accuracy of vowel identification for naturally-produced CV sequences varied depending on the extent of anticipatory vowel coarticulation. Speakers and speech tokens included those characterized by an average degree of anticipatory coarticulation, a high degree of coarticulation, and a low degree of coarticulation. Healthy talkers, speakers with multiple sclerosis, and speakers with Parkinson's disease produced the stimuli. Consonants in CV syllables beginning with /s/, /k/, or /t/ followed by the vowels /i/ or /u/ were excised and presented to listeners for identification of the following vowel. While identification accuracy may be high across speakers and stimuli, the speed of response should vary with extent of coarticulation, if listeners are sensitive to coarticulatory cues in the acoustic speech stream.

The impact of musical training and tone language experience on talker identification.  

PubMed

Listeners can use pitch changes in speech to identify talkers. Individuals exhibit large variability in sensitivity to pitch and in accuracy perceiving talker identity. In particular, people who have musical training or long-term tone language use are found to have enhanced pitch perception. In the present study, the influence of pitch experience on talker identification was investigated as listeners identified talkers in native language as well as non-native languages. Experiment 1 was designed to explore the influence of pitch experience on talker identification in two groups of individuals with potential advantages for pitch processing: musicians and tone language speakers. Experiment 2 further investigated individual differences in pitch processing and the contribution to talker identification by testing a mediation model. Cumulatively, the results suggested that (a) musical training confers an advantage for talker identification, supporting a shared resources hypothesis regarding music and language and (b) linguistic use of lexical tones also increases accuracy in hearing talker identity. Importantly, these two types of hearing experience enhance talker identification by sharpening pitch perception skills in a domain-general manner. PMID:25618071

When susceptible-infectious-susceptible contagion meets time-varying networks with identical infectivity  

NASA Astrophysics Data System (ADS)

Transmission of infectious diseases among populations can be modelled as contagion processes on contact networks. These contact networks are highly evolved in time and are represented by time-varying networks. The agents in contagion processes may have finite infectivity independently of their connectivity. Here we present an analytical framework of the susceptible-infectious-susceptible contagion process on time-varying networks, namely activity-driven networks with identical infectivity. We derive the critical epidemic thresholds and immunization thresholds as a function of infectivity, and prove that targeted immunizations are more efficient than random immunizations independently of the infectivity. We validate our conclusions in a large-scale human indoor interaction data set. Finally, we assess the effects of finite size.

The relationship of the whole genome sequence identity to DNA hybridization varies between genera of prokaryotes.  

PubMed

In the original proposal of Wayne et al. (Int J Syst Bacteriol 37:463-464, 1987), two measures of genetic relatedness were proposed to set the boundary for prokaryotic species. The first was the change in the melting temperature (?Tm) of heteroduplex DNA and the second was the extent of DNA-DNA hybridization (DDH). While this approach was justified given the experimental error inherent in these methods, genomic sequencing has the potential to measure both parameters with great precision. The average nucleotide identity (ANIb), a surrogate for the ?Tm, and the calculated DDH (cDDH) were determined from the complete genomes of representatives of 17 genera of prokaryotes. When the ANIb was >75 %, the ratio (100-cDDH)/(100-ANIb) was 3.69 ± 0.93 (± SD) and varied from about 2.35 to 4.59 between genera. The differences among genera was highly significant (p < 0.001) but not correlated with specific phylogenetic or physiological groups. Moreover, the ANIm was a poor measure of ANIb when ANIb was <75 %. Because the ANIb and cDDH provide different measures of relatedness, it is no longer appropiate to consider both when delineating species. For these reasons, measures of relatedness based upon sequence identity should be used for delineating species in the future. PMID:25370015

Effects of fundamental frequency and vocal-tract length changes on attention to one of two simultaneous talkers  

NASA Astrophysics Data System (ADS)

Three experiments used the Coordinated Response Measure task to examine the roles that differences in F0 and differences in vocal-tract length have on the ability to attend to one of two simultaneous speech signals. The first experiment asked how increases in the natural F0 difference between two sentences (originally spoken by the same talker) affected listeners' ability to attend to one of the sentences. The second experiment used differences in vocal-tract length, and the third used both F0 and vocal-tract length differences. Differences in F0 greater than 2 semitones produced systematic improvements in performance. Differences in vocal-tract length produced systematic improvements in performance when the ratio of lengths was 1.08 or greater, particularly when the shorter vocal tract belonged to the target talker. Neither of these manipulations produced improvements in performance as great as those produced by a different-sex talker. Systematic changes in both F0 and vocal-tract length that simulated an incremental shift in gender produced substantially larger improvements in performance than did differences in F0 or vocal-tract length alone. In general, shifting one of two utterances spoken by a female voice towards a male voice produces a greater improvement in performance than shifting male towards female. The increase in performance varied with the intonation patterns of individual talkers, being smallest for those talkers who showed most variability in their intonation patterns between different utterances.

Some effects of talker variability on spoken word recognition  

PubMed Central

The perceptual consequences of trial-to-trial changes in the voice of the talker on spoken word recognition were examined. The results from a series of experiments using perceptual identification and naming tasks demonstrated that perceptual performance decreases when the voice of the talker changes from trial to trial compared to performance when the voice on each trial remains the same. In addition, the effects of talker variability on word recognition appeared to be more robust and less dependent on task than the effects of word frequency and lexical structure. Possible hypotheses regarding the nature of the processes giving rise to these effects are discussed, with particular attention to the idea that the processing of information about the talker’s voice is intimately related to early perceptual processes that extract acoustic–phonetic information from the speech signal.

A Time Varying Evaluation of Identity Theory and Father Involvement for Full Custody, Shared Custody, and No Custody Divorced Fathers  

PubMed Central

This study tested identity theory models of father involvement for 230 divorced fathers of young children aged 4 to 11 followed over 18 months. Research questions were (1) Do measures of identity salience and centrality of the fathering role predict fathering involvement over time? (2) Does father involvement predict fathering identity over time? (3) Does father custody moderate these relationships? Involvement was assessed as contact frequency, number of father-child activities, and positive involvement observed during father-child interaction. Comparisons showed that the quantity of involvement differed by custody but there were few differences in the quality of involvement. Fathers did not exhibit significant mean decreases in involvement and custodial groups did not differ in the growth rates for involvement nor identity measures. However, there were significant individual differences in growth rates, meaning there was variance in fathers increasing and decreasing in measures over time. Time 1 father identities, measured as salience and centrality, predicted days per month, overnights per month, and father child activities over time. Time-varying predictors suggested that identities were more predictive of growth in involvement than vice versa although father involvement predicted salience and primarily centrality. Implications for practice and future research are discussed. PMID:20617120

Experience with a Talker Can Transfer Across Modalities to Facilitate Lipreading  

PubMed Central

Rosenblum, Miller, and Sanchez (2007) found that participants first trained to lipread a particular talker were then better able to perceive the auditory speech of that same talker, compared to that of a novel talker. This suggests that the talker experience a perceiver gains in one sensory modality can be transferred to another modality to make that speech easier to perceive. An experiment was conducted to examine whether this cross-sensory transfer of talker experience could occur: 1) from auditory to lipread speech; 2) with subjects not screened for adequate lipreading skill; 3) when both a familiar and unfamiliar talker are presented during lipreading; and 4) for both old (presentation set) and new words. Subjects were first asked to identify a set of words from a talker. They were then asked to perform a lipreading task from two faces, one of which was of the same talker they heard in the first phase of the experiment. Results revealed that subjects who lipread from the same talker they had heard performed better than those who lipead a different talker, regardless of whether the words were old or new. These results add further evidence that learning of amodal talker information can facilitate speech perception across modalities and also suggest that this information is not restricted to previously heard words.

Identification of 20-ms speech samples from normal and neurologically impaired talkers: Do coarticulation differences matter?  

NASA Astrophysics Data System (ADS)

Prior studies of speech suggest that the extent of coarticulation varies both across and within talkers. Speakers sometime use average, high, or low amounts of coarticulation. The perceptual consequences of coarticulatory variability are not well understood, particularly for the speech of individuals with motor control disorders. In the current study, listeners heard the same 20-ms tokens that were used to calculate the degree of anticipatory coarticulation of the following vowel. Acoustic measures were made from the first 20 ms of stop consonants [k] or [t], or from a point 70 ms preceding the vowel in [s] productions. Healthy talkers, speakers with Multiple Sclerosis, and speakers with Parkinson's disease produced the stimuli. Speech tokens included three degrees of anticipatory coarticulation: average, high, and low. The listeners' task was to identify whether the vowels that followed the consonant were originally [i] or [u]. Results showed that identification accuracy was poorer for the current 20-ms tokens than for prior speech samples including all aperiodicity of consonants. Identification was poorest for [s] and best for [k] tokens. The speed of listener response gave some indication of the differing extents of coarticulation. Perceptual validity for the 20-ms measure of coarticulation is discussed.

The Effect of Talker Variability on Word Recognition in Preschool Children  

PubMed Central

In a series of experiments, the authors investigated the effects of talker variability on children’s word recognition. In Experiment 1, when stimuli were presented in the clear, 3- and 5-year-olds were less accurate at identifying words spoken by multiple talkers than those spoken by a single talker when the multiple-talker list was presented first. In Experiment 2, when words were presented in noise, 3-, 4-, and 5-year-olds again performed worse in the multiple-talker condition than in the single-talker condition, this time regardless of order; processing multiple talkers became easier with age. Experiment 3 showed that both children and adults were slower to repeat words from multiple-talker than those from single-talker lists. More important, children (but not adults) matched acoustic properties of the stimuli (specifically, duration). These results provide important new information about the development of talker normalization in speech perception and spoken word recognition. PMID:9149923

Perception of speech produced by native and nonnative talkers by listeners with normal hearing and listeners with cochlear implants.  

PubMed

PURPOSE The aim of this study was to evaluate the understanding of English sentences produced by native (English) and nonnative (Spanish) talkers by listeners with normal hearing (NH) and listeners with cochlear implants (CIs). METHOD Sentence recognition in noise was measured in adult subjects with CIs and subjects with NH, all of whom were native talkers of American English. Test sentences were from the Hearing in Noise Test (HINT) database and were produced in English by four native and eight nonnative talkers. Subjects also rated the intelligibility and accent for each talker. RESULTS The speech recognition thresholds in noise of subjects with CIs and subjects with NH were 4.23 dB and 1.32 dB poorer with nonnative talkers than with native talkers, respectively. Performance was significantly correlated with talker intelligibility and accent ratings for subjects with CIs but only correlated with talker intelligibility ratings for subjects with NH. For all subjects, performance with individual nonnative talkers was significantly correlated with talkers' number of years of residence in the United States. CONCLUSION CI users exhibited a larger deficit in speech understanding with nonnative talkers than did subjects with NH, relative to native talkers. Nonnative talkers' experience with native culture contributed strongly to speech understanding in noise, intelligibility ratings, and accent ratings of both listeners with NH and listeners with CIs.

Interlanguage intelligibility benefit as a function of talker and listener language background and L2 proficiency  

NASA Astrophysics Data System (ADS)

For non-native listeners, intelligibility of non-native speakers (NNS) can surpass intelligibility of native speakers [T. Bent, J. Acoust. Soc. Am. 109, 2472 (2001)]. The present study further investigated how language background and L2 proficiency of talker and listener affect L2 intelligibility. Two Chinese NNS, two Korean NNS, and one English monolingual were recorded reading simple English sentences. Listeners were English monolinguals, Chinese NNS, Korean NNS, and NNS with other L1s. For native English listeners, the native English talker was most intelligible. For non-native listeners, intelligibility of non-native talkers with high degrees of L2 proficiency was better than or equal to native talker intelligibility. This pattern held regardless of whether non-native talkers and listeners matched in L1. Additionally, the interlanguage benefit (i.e., the intelligibility difference between non-native and native talkers) decreased as the listeners' proficiency in English increased. This interlanguage benefit can be accounted for by a combination of a shared systematic interlanguage (when talker and listener match in L1) and the influence of interlanguage universals (when talker and listener do not match in L1). However, both of these factors become less influential as listeners L2 proficiency develops causing a decrease in the interlanguage benefit. [Work supported by NIH-NIDCD Grant DC 03762.

Phoneme contrasts with two, same-talker speakers  

NASA Astrophysics Data System (ADS)

People often have difficulty hearing speech in the presence of concurrent conversations. This well-known cocktail-party effect can be parsed into energetic and informational masking effects. The purpose of this study was to measure and model the effects of energetic and informational masking that occur when two words, spoken by the same talker are heard at the same time. The word identification test used in the experiments was the Modified Rhyme Test (MRT). The MRT was used as both the stimulus and the masker, which afforded a multitude of consonant contrasts. The phrases were presented monaurally at 75 dB SPL over Sennheiser HD-520 headphones to four normal hearing listeners. The independent variables included 30 pairs of MRT word lists spoken by three male and three female talkers. The dependent variable was the percent correct identifications of the two consonants. Listeners performed at 94% correct for the first word choice and 72% correct for the second word choice. The distribution of errors was analyzed by place of articulation, manner of articulation, and speech-to-speech-ratio of the phoneme pairs and compared to articulation index predictions for speech intelligibility.

In 3 experiments, participants were required to perform a lexical decision task on a target item embedded in backgrounds composed of 1–4 voices. These voices were Semantically Consistent (SC) voices (i.e., pronouncing words sharing semantic features with the target) or Semantically Inconsistent (SI) voices (i.e., pronouncing words semantically unrelated to each other and to the target). In the first experiment, backgrounds consisted of 1 or 2 SC voices. One and 2 SI voices were added in Experiments 2 and 3, respectively. The results showed a semantic priming effect only in the conditions where the number of SC voices was greater than the number of SI voices, suggesting that semantic priming depended on prime intelligibility and strategic processes. However, even if backgrounds were composed of 3 or 4 voices, reducing intelligibility, participants were able to recognize words from these backgrounds, although no semantic priming effect on the targets was observed. Overall this finding suggests that informational masking can occur at a semantic level if intelligibility is sufficient. Based on the Effortfulness Hypothesis, we also suggest that when there is an increased difficulty in extracting target signals (caused by a relatively high number of voices in the background), more cognitive resources were allocated to formal processes (i.e., acoustic and phonological), leading to a decrease in available resources for deeper semantic processing of background words, therefore preventing semantic priming from occurring.

The mechanisms underlying the poorer serial recall of talker-variable lists (e.g., alternating female-male voices) as compared with single-voice lists were examined. We tested the novel hypothesis that this "talker variability effect" arises from the tendency for perceptual organization to partition the list into streams based on voice such that…

Consonant identification in N-talker babble is a nonmonotonic function of N  

NASA Astrophysics Data System (ADS)

Consonant identification rates were measured for vowel-consonant-vowel tokens gated with N-talker babble noise and babble-modulated noise for an extensive range of N, at a fixed signal-to-noise ratio. In the natural babble condition, intelligibility was a nonmonotonic function of N, with a broad performance minimum from N=6 to N=128. Identification rates in babble-modulated noise fell gradually with N. The contributions of factors such as energetic masking, linguistic confusion, attentional load, peripheral adaptation, and stationarity to the perception of consonants in N-talker babble are discussed.

Speaking rate effects on articulatory pattern consistency in talkers with mild ALS.  

PubMed

This study investigated speaking rate effects on articulatory pattern consistency in talkers with mild amyotrophic lateral sclerosis (ALS) to better understand speech rate declines during the early stages of speech deterioration. Eight talkers with mild ALS and 11 controls repeated a sentence at their typical rate, an accelerated rate, and a reduced rate. Lip and jaw movements were captured using a 3-D motion capture system. Results showed that talkers with ALS produced more consistent articulatory patterns during typical speech than did controls. Further, rate reduction resulted in diminished pattern consistency in both groups. Fast speech also elicited less consistent articulatory patterns in talkers with ALS. Controls, by contrast, tended to produce more consistent patterns during fast speech. Relatively inconsistent patterns during fast speech suggest that ALS may negatively affect articulatory control when the speech motor system operates near its performance limit. Relatively consistent patterns during typical speech indicate a successful adaption to disease-related articulatory deficits. Rate reduction does not appear to benefit articulatory stability during early stages of speech decline. PMID:24724615

Vocal effort with changing talker-to-listener distance in different acoustic environments.  

PubMed

Talkers adjust their vocal effort to communicate at different distances, aiming to compensate for the sound propagation losses. The present paper studies the influence of four acoustically different rooms on the speech produced by 13 male talkers addressing a listener at four distances. Talkers raised their vocal intensity by between 1.3 and 2.2 dB per double distance to the listener and lowered it as a linear function of the quantity "room gain" at a rate of -3.6 dB/dB. There were also significant variations in the mean fundamental frequency, both across distance (3.8 Hz per double distance) and among environments (4.3 Hz), and in the long-term standard deviation of the fundamental frequency among rooms (4 Hz). In the most uncomfortable rooms to speak in, talkers prolonged the voiced segments of the speech they produced, either as a side-effect of increased vocal intensity or in order to compensate for a decrease in speech intelligibility.

Comparison of bimodal and bilateral cochlear implant users on speech recognition with competing talker, music perception, affective prosody discrimination and talker identification  

PubMed Central

Objectives Despite excellent performance in speech recognition in quiet, most cochlear implant users have great difficulty with speech recognition in noise, music perception, identifying tone of voice, and discriminating different talkers. This may be partly due to the pitch coding in cochlear implant speech processing. Most current speech processing strategies use only the envelope information; the temporal fine structure is discarded. One way to improve electric pitch perception is to utilize residual acoustic hearing via a hearing aid on the non-implanted ear (bimodal hearing). This study aimed to test the hypothesis that bimodal users would perform better than bilateral cochlear implant users on tasks requiring good pitch perception. Design Four pitch-related tasks were used: Hearing in Noise Test (HINT) sentences spoken by a male talker with a competing female, male, or child talker. Montreal Battery of Evaluation of Amusia. This is a music test with six subtests examining pitch, rhythm and timing perception, and musical memory. Aprosodia Battery. This has five subtests evaluating aspects of affective prosody and recognition of sarcasm. Talker identification using vowels spoken by ten different talkers (three male, three female, two boys, and two girls). Bilateral cochlear implant users were chosen as the comparison group. Thirteen bimodal and thirteen bilateral adult cochlear implant users were recruited; all had good speech perception in quiet. Results There were no significant differences between the mean scores of the bimodal and bilateral groups on any of the tests, although the bimodal group did perform better than the bilateral group on almost all tests. Performance on the different pitch-related tasks was not correlated, meaning that if a subject performed one task well they would not necessarily perform well on another. The correlation between the bimodal users' hearing threshold levels in the aided ear and their performance on these tasks was weak. Conclusions Although the bimodal cochlear implant group performed better than the bilateral group on most parts of the four pitch-related tests, the differences were not statistically significant. The lack of correlation between test results shows that the tasks used are not simply providing a measure of pitch ability. Even if the bimodal users have better pitch perception, the real-world tasks used are reflecting more diverse skills than pitch. This research adds to the existing speech perception, language, and localization studies that show no significant difference between bimodal and bilateral cochlear implant users. PMID:21178567

Parental phonological memory contributes to prediction of outcome of late talkers from 20 months to 4 years: a longitudinal study of precursors of specific language impairment  

PubMed Central

Background Many children who are late talkers go on to develop normal language, but others go on to have longer-term language difficulties. In this study, we considered which factors were predictive of persistent problems in late talkers. Methods Parental report of expressive vocabulary at 18 months of age was used to select 26 late talkers and 70 average talkers, who were assessed for language and cognitive ability at 20 months of age. Follow-up at 4 years of age was carried out for 24 late and 58 average talkers. A psychometric test battery was used to categorize children in terms of language status (unimpaired or impaired) and nonverbal ability (normal range or more than 1 SD below average). The vocabulary and non-word repetition skills of the accompanying parent were also assessed. Results Among the late talkers, seven (29%) met our criteria for specific language impairment (SLI) at 4 years of age, and a further two (8%) had low nonverbal ability. In the group of average talkers, eight (14%) met the criteria for SLI at 4 years, and five other children (8%) had low nonverbal ability. Family history of language problems was slightly better than late-talker status as a predictor of SLI.. The best predictors of SLI at 20 months of age were score on the receptive language scale of the Mullen Scales of Early Learning and the parent's performance on a non-word repetition task. Maternal education was not a significant predictor of outcome. Conclusions In this study, around three-quarters of late talkers did not have any language difficulties at 4 years of age, provided there was no family history of language impairment. A family history of language-literacy problems was found to be a significant predictor for persisting problems. Nevertheless, there are children with SLI for whom prediction is difficult because they did not have early language delay. PMID:22958373

Dimensional feature weighting utilizing multiple kernel learning for single-channel talker location discrimination using the acoustic transfer function.  

PubMed

This paper presents a method for discriminating the location of the sound source (talker) using only a single microphone. In a previous work, the single-channel approach for discriminating the location of the sound source was discussed, where the acoustic transfer function from a user's position is estimated by using a hidden Markov model of clean speech in the cepstral domain. In this paper, each cepstral dimension of the acoustic transfer function is newly weighted, in order to obtain the cepstral dimensions having information that is useful for classifying the user's position. Then, this paper proposes a feature-weighting method for the cepstral parameter using multiple kernel learning, defining the base kernels for each cepstral dimension of the acoustic transfer function. The user's position is trained and classified by support vector machine. The effectiveness of this method has been confirmed by sound source (talker) localization experiments performed in different room environments. PMID:23363107

Talker sex mediates the influence of neighborhood density on vowel articulation  

NASA Astrophysics Data System (ADS)

Words with high phonological neighborhood densities (ND) are more difficult to perceive than words with low NDs [P. Luce and D. Pisoni (1998)]. Previous research has shown that the F1/F2 acoustic vowel space is larger for vowels in words with high ND relative to words with low NDs [B. Munson and N.P. Solomon (2004); R. Wright (2004)]. This may represent talkers' tacit attempts to partially counter the perception difficulties associated with high-ND words. If so, then we would expect to see a larger effect of ND on vowel articulation in women, who have been observed to produce more intelligible speech than men, and to accommodate more to conversational partners than men [V. Hazan and D. Markham (2004); L. Namy et al. (2002)]. This hypothesis was tested by examining the influence of ND on vowel-space articulation by 22 women and 22 men. As expected, women produced overall more-dispersed vowel spaces than men, and vowel spaces associated with high-ND words were more-dispersed than low-ND words. Contrary to expectations, the influence of ND on vowel-space expansion was strongest in men. This appeared to be due a tendency for women not to produce contracted vowel spaces for low-ND words.

Auditory measures of selective and divided attention in young and older adults using single-talker competition.  

PubMed

In this study, two experiments were conducted on auditory selective and divided attention in which the listening task involved the identification of words in sentences spoken by one talker while a second talker produced a very similar competing sentence. Ten young normal-hearing (YNH) and 13 elderly hearing-impaired (EHI) listeners participated in each experiment. The type of attention cue used was the main difference between experiments. Across both experiments, several consistent trends were observed. First, in eight of the nine divided-attention tasks across both experiments, the EHI subjects performed significantly worse than the YNH subjects. By comparison, significant differences in performance between age groups were only observed on three of the nine selective-attention tasks. Finally, there were consistent individual differences in performance across both experiments. Correlational analyses performed on the data from the 13 older adults suggested that the individual differences in performance were associated with individual differences in memory (digit span). Among the elderly, differences in age or differences in hearing loss did not contribute to the individual differences observed in either experiment. PMID:17139749

Predicting the effect of hearing loss and audibility on amplified speech reception in a multi-talker listening scenario.  

PubMed

Auditive and cognitive influences on speech perception in a complex situation were investigated in listeners with normal hearing (NH) and hearing loss (HL). The speech corpus used was the Nonsense-Syllable Response Measure [NSRM; Woods and Kalluri, (2010). International Hearing Aid Research Conference, pp. 40-41], a 12-talker corpus which combines 154 nonsense syllables with 8 different carrier phrases. Listeners heard NSRM sentences in quiet, background noise, and in background noise plus other "jammer" NSRM sentences. All stimuli were linearly amplified. A "proficiency" value, determined from the results in quiet and the quiet-condition speech intelligibility index (SII), was used with the SII in predicting results in the other conditions. Results for nine of ten NH subjects were well-predicted (within the limits of binomial variability) in the noise condition, as were eight of these subjects in the noise-plus-jammers condition. All 16 HL results were well-predicted in the noise condition, as were 9 of the HL in the noise-plus-jammers condition. Hierarchical regression partialling out the effects of age found proficiency in noise-plus-jammers significantly correlated with results of "trail-making" tests, thought to index processing speed and attention-deployment ability, and proficiency in quiet and noise was found significantly correlated with results from a backward digit-span memory test.

In the first part of this paper we consider the transformation of the cubic identities for general Korteweg-de Vries (KdV) tau functions from [Mishev, J. Math. Phys. 40, 2419-2428 (1999)] to the specific identities for trigonometric KdV tau functions. Afterwards, we consider the Fay identity as a functional equation and provide a wide set of solutions of this equation. The main result of this paper is Theorem 3.4, where we generalize the identities from Mishev. An open problem is the transformation of the cubic identities from Mishev to the specific identities for elliptic KdV tau functions.

Varying constants quantum cosmology  

NASA Astrophysics Data System (ADS)

We discuss minisuperspace models within the framework of varying physical constants theories including ?-term. In particular, we consider the varying speed of light (VSL) theory and varying gravitational constant theory (VG) using the specific ansätze for the variability of constants: c(a) = c0 an and G(a)=G0 aq. We find that most of the varying c and G minisuperspace potentials are of the tunneling type which allows to use WKB approximation of quantum mechanics. Using this method we show that the probability of tunneling of the universe ``from nothing'' (a=0) to a Friedmann geometry with the scale factor at is large for growing c models and is strongly suppressed for diminishing c models. As for G varying, the probability of tunneling is large for G diminishing, while it is small for G increasing. In general, both varying c and G change the probability of tunneling in comparison to the standard matter content (cosmological term, dust, radiation) universe models.

This chapter explores characteristics of identity formation among Japanese adolescents and young adults living in a cultural context where individualism has been increasingly emphasized even while maintaining collectivism. We argue that, to develop a sense of identity in Japanese culture, adolescents and young adults carefully consider others' perspectives, resolve conflicts between self and others, and, in some cases, merge themselves into relationships and groups rather than pursuing their own uniqueness. However, at the same time, as Japanese society changes in various ways, such as the educational and employment systems, a traditional type of identity may gradually become less functional. A new identity configuration, individualistic collectivism, emerges. We also provide future directions for research toward a more global understanding of identity formation among Japanese adolescents and young adults. PMID:23225357

Finer grained spatial and temporal data and more reliable communications make it easier to model dynamic states and ephemeral features. The exchange of information within and across geospatial domains is facilitated through the use of harmonized information models. The Observations & Measurements (O&M) developed through OGC and standardised by ISO is an example of such a cross-domain information model. It is used in many domains, including meteorology, hydrology as well as the emergency management. O&M enables harmonized representation of common metadata that belong to the act of determining the state of a feature property, whether by sensors, simulations or humans. In addition to the resulting feature property value, information such as the result quality but especially the time that the result applies to the feature property can be represented. Temporal metadata is critical to modelling past and future states of a feature. The features, and the semantics of each property, are defined in domain specific Application Schema using the General Feature Model (GFM) from ISO 19109 and usually encoded following ISO 19136. However, at the moment these standards provide only limited support for the representation and handling of time varying feature data. Features like rivers, wildfires or gas plumes have a defined state - for example geographic extent - at any given point in time. To keep track of changes, a more complex model for example using time-series coverages is required. Furthermore, the representation and management of feature property value changes via the service interfaces defined by OGC and ISO - namely: WFS and WCS - would be rather complex. Keeping track of feature property value corrections or even feature (state change) cancellations for auditing purposes is also not easy to achieve. The aviation domain has strong requirements to represent and manage the state of aeronautical features through time. Being able to efficiently encode and manage feature state changes, keeping track of all changes for auditing purposes and being able to determine the future state of an aeronautical feature as currently known to the system are vital for aeronautical applications. In order to support these requirements, the Aeronautical Information Exchange Model (AIXM) which has been developed by the aviation domain is based on the so called AIXM Temporality Model (AIXM-TM). The AIXM-TM defines various rules for modeling, representing and handling the state of aeronautical features through time. This is a promising approach that can be incorporated into the GFM so that ultimately the modeling and management of time varying feature data is supported in an interoperable and harmonized way in all geospatial domains. This presentation gives an introduction to the main concepts of the AIXM-TM. It also shows how the GFM can be extended to support time varying feature data. Finally, the relationship of O&M and time varying features is discussed.

Identity and intimacy during adolescence: connections among identity styles, romantic attachment and identity commitment.  

PubMed

Integration of adult attachment and psychosocial development theories suggests that adolescence is a time when capacities for romantic intimacy and identity formation are co-evolving. The current study addressed direct, indirect and moderated associations among identity and romantic attachment constructs with a diverse sample of 2178 middle adolescents. Identity styles were found to have unique and direct associations with identity commitment. Attachment anxiety showed only indirect associations and attachment avoidance had both direct and indirect associations with identity commitment. Tests of moderation revealed that gender, race and relationship status had no influence on the direct associations of identity styles or romantic attachment with identity commitment. Few differences in association strength among identity styles and romantic attachment emerged for gender or race. However, the differences found for relationship status suggested that relationship experiences adolescents bring to their exploration of identity and intimacy matter for how these two areas of development articulate.

Online Identities and Social Networking  

NASA Astrophysics Data System (ADS)

Online identities play a critical role in the social web that is taking shape on the Internet. Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

Gender identity development in adolescence.  

PubMed

This article is part of a Special Issue "Puberty and Adolescence".This article aims to provide an outline of what is currently known on trajectories, and contributing factors to gender identity development in adolescence. We give a historical overview of the concept of gender identity, and describe general identity development in adolescence, gender identity development in the general population and in gender variant youth. Possible psychosocial (such as child and parental characteristics) and biological factors (such as the effects of prenatal exposure to gonadal hormones and the role of genetics) contributing to a gender variant identity are discussed. Studies focusing on a number of psychosocial and biological factors separately, indicate that each of these factors influence gender identity formation, but little is known about the complex interplay between the factors, nor about the way individuals themselves contribute to the process. Research into normative and gender variant identity development of adolescents is clearly lagging behind. However, studies on persons with gender dysphoria and disorders of sex development, show that the period of adolescence, with its changing social environment and the onset of physical puberty, seems to be crucial for the development of a non-normative gender identity.

Body Integrity Identity Disorder  

PubMed Central

Introduction Body Integrity Identity Disorder (BIID) is a rare, infrequently studied and highly secretive condition in which there is a mismatch between the mental body image and the physical body. Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. Methods Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation) were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. Results Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification. Conclusions The amputation variant and paralyzation variant of BIID are to be considered as one of the same condition. Amputation of the healthy body part appears to result in remission of BIID and an impressive improvement of quality of life. Knowledge of and respect for the desires of BIID individuals are the first steps in providing care and may decrease the huge burden they experience. PMID:22514657

Young African American children constructing identities in an urban integrated science-literacy classroom  

NASA Astrophysics Data System (ADS)

This is a qualitative study of identities constructed and enacted by four 3rd-grade African American children (two girls and two boys) in an urban classroom that engaged in a year-long, integrated science-literacy project. Juxtaposing narrative and discursive identity lenses, coupled with race and gender perspectives, I examined the ways in which the four children saw and performed themselves as students and as science students in their classroom. Interview data were used for the narrative analysis and classroom Discourse and artifacts were used for the discursive analysis. A constructivist grounded theory framework was adopted for both analyses. The findings highlight the diversity and richness of perspectives and forms of engagement these young children shared and enacted, and help us see African American children as knowers, doers, and talkers of science individually and collectively. In their stories about themselves, all the children identified themselves as smart but they associated with smartness different characteristics and practices depending on their strengths and preferences. Drawing on the children's social, cultural, and ethnolinguistic resources, the dialogic and multimodal learning spaces facilitated by their teacher allowed the children to explore, negotiate, question, and learn science ideas. The children in this study brought their understandings and ways of being into the "lived-in" spaces co-created with classmates and teacher and influenced how these spaces were created. At the same time, each child's ways of being and understandings were shaped by the words, actions, behaviors, and feelings of peers and teacher. Moreover, as these four children engaged with science-literacy activities, they came to see themselves as competent, creative, active participants in science learning. Although their stories of "studenting" seemed dominated by following rules and being well-behaved, their stories of "sciencing" were filled with exploration, ingenuity, risk taking, and thinking. The study calls for (a) research that is positioned within children's perspectives and give voice to the experiences of African American children in urban schools, (b) teacher education that supports teachers' efforts to help urban school students become academically successful, and (c) policy that foregrounds identity development along with subject-matter learning.

Beyond pain and protection: politics of identity and iban girls in Korea.  

PubMed

This study analyzes the complexities in the exploration of iban girls' identities and the various ways how girls appropriate varied sources such as popular culture to examine the heterogeneousness of identity explorations and rethink the politics of identities. Against the tendency in current discourse on homosexual youth in Korea, protection discourse and pain discourse, the notion of identity itself will be critically examined and the girls' agency in destabilizing heteronormativity will be discussed. This study also deals with the appropriation of popular culture by the girls, suggesting that cultural critiques should reveal complex dynamics in concrete experiences. doi:10.1300/J155v10n03_04.

Varying-? and K-essence  

NASA Astrophysics Data System (ADS)

We introduce a model which allows the fine structure constant (?) to vary throughout space and time due to a coupling to a scalar field with a non-canonical kinetic structure. This provided a new extension of the Bekenstein-Sandvik-Barrow-Magueijo model of ? variations. The background cosmology is studied in detail using dynamical systems techniques for a scalar field of ghost condensate type. We show generically that if the kinetic terms are chosen to allow an accelerated late-time attractor for the expansion scale factor then ? will not asymptote to a constant at late times.

Local Varying-Alpha Theories  

E-print Network

In a recent paper we demonstrated how the simplest model for varying alpha may be interpreted as the effect of a dielectric material, generalized to be consistent with Lorentz invariance. Unlike normal dielectrics, such a medium cannot change the speed of light, and its dynamics obey a Klein-Gordon equation. This work immediately suggests an extension of the standard theory, even if we require compliance with Lorentz invariance. Instead of a wave equation, the dynamics may satisfy a local algebraic relation involving the permittivity and the properties of the electromagnetic field, in analogy with more conventional dielectric (but still preserving Lorentz invariance). We develop the formalism for such theories and investigate some phenomenological implications. The problem of the divergence of the classical self-energy can be solved, or at least softened, in this framework. Some interesting new cosmological solutions for the very early universe are found, including the possibility of a bounce, inflation and e...

Interdisciplinary Thinking and Physics Identity  

NSDL National Science Digital Library

One goal of education is to help students become well-rounded citizens who can think broadly across boundaries. In addition, individuals with interdisciplinary thinking skills can be valuable contributors to modern research challenges by understanding and recognizing interdisciplinary connections and working in diverse teams. However, little research exists on the connection between interdisciplinary thinking and physics education. What aspects of physics classroom practices and experiences foster interdisciplinary thinking? What effect does interdisciplinary thinking have on the development of studentsâ physics identities? Using a physics identity theoretical framework with data from a national survey, this study found that self-reported characteristics of interdisciplinary thinking are significantly correlated with higher levels of physics identity development. Also, several factors of the physics classroom environment and pedagogies are significantly related to interdisciplinary thinking.

However, people sometimes say that two objects, "x" and "z," are the same as a third, "y," even when "x" and "z" have different properties (thus, "x = y" and "y = z," but "x is not equal to z").

Quantum MacWilliams Identities  

E-print Network

We derive a relationship between two different notions of fidelity (entanglement fidelity and average fidelity) for a completely depolarizing quantum channel. This relationship gives rise to a quantum analog of the MacWilliams identities in classical coding theory. These identities relate the weight enumerator of a code to the one of its dual and, with linear programming techniques, provided a powerful tool to investigate the possible existence of codes. The same techniques can be adapted to the quantum case. We give examples of their power.

Absorption properties of identical atoms  

SciTech Connect

Emission rates and other optical properties of multi-particle systems in collective and entangled states differ from those in product ones. We show the existence of similar effects in the absorption probabilities for (anti)symmetrized states of two identical atoms. The effects strongly depend on the overlapping between the atoms and differ for bosons and fermions. We propose a viable experimental verification of these ideas. -- Highlights: •The absorption rates of a pair of identical atoms in product and (anti)symmetrized states are different. •The modifications of the optical properties are essentially determined by the overlapping between the atoms. •The absorption properties differ, in some cases, for bosons and fermions.

Changes in Identity after Aphasic Stroke: Implications for Primary Care  

PubMed Central

Background. Stroke survivors with aphasia experience difficulty associated with their communication disorder. While much has been written about aphasia's impacts on partners/family, we lack data regarding the psychosocial adjustment of aphasic stroke survivors, with a paucity of data from the patients themselves. Methods. Qualitative study of lived experiences of individuals with poststroke aphasia. Each of the stroke survivors with aphasia completed 3-4 semistructured interviews. In most cases, patients' partners jointly participated in interviews, which were transcribed and analyzed using techniques derived from grounded theory. Results. 12 patients were interviewed, with the total of 45 interviews over 18 months. Themes included poststroke changes in patients' relationships and identities, which were altered across several domains including occupational identity, relationship and family roles, and social identity. While all these domains were impacted by aphasia, the impact varied over time. Conclusion. Despite the challenges of interviewing individuals with aphasia, we explored aphasia's impacts on how individuals experience their identity and develop new identities months and years after stroke. This data has important implications for primary care of patients with aphasia, including the importance of the long-term primary care relationship in supporting psychosocial adjustment to life after aphasic stroke.

[Identity and narration: autobiographical quests].  

PubMed

This paper aims to tackle the subtle relation between autobiographical narratives and identity construction, from a non essentialist conception of identity. In a perspective that articulates philosophy of language, psychoanalysis, semiotics and literary critique, we posit the concept of biographical space as an analytical instrument to make a critical update of the reconfiguration of identities and subjectivities in contemporary culture, marked by the predominance of the biographical, the private and a kind of "public intimacy". This look is more symptomatic than descriptive: it intends to account for the rise of auto/biographical narratives and life-stories, from canonic genres to their multiple derivations in the media, social networks and the most diverse artistic practices, a phenomenon that seems to reaffirm the notion of narrative identities by Ricoeur. Our analysis here, from an ethic, aesthetic and political point of view, will focus on two visual arts experiences that have recently taken place for the first time in Buenos Aires: Christian Boltanski's and Tracey Emin's, solo exhibitions, each of them with a different biographical approach.

Variational identities and Hamiltonian structures  

SciTech Connect

This report is concerned with Hamiltonian structures of classical and super soliton hierarchies. In the classical case, basic tools are variational identities associated with continuous and discrete matrix spectral problems, targeted to soliton equations derived from zero curvature equations over general Lie algebras, both semisimple and non-semisimple. In the super case, a supertrace identity is presented for constructing Hamiltonian structures of super soliton equations associated with Lie superalgebras. We illustrate the general theories by the KdV hierarchy, the Volterra lattice hierarchy, the super AKNS hierarchy, and two hierarchies of dark KdV equations and dark Volterra lattices. The resulting Hamiltonian structures show the commutativity of each hierarchy discussed and thus the existence of infinitely many commuting symmetries and conservation laws.

Silos and Social Identity: The Social Identity Approach as a Framework for Understanding and Overcoming Divisions in Health Care  

PubMed Central

Context One of health care's foremost challenges is the achievement of integration and collaboration among the groups providing care. Yet this fundamentally group-related issue is typically discussed in terms of interpersonal relations or operational issues, not group processes. Methods We conducted a systematic search for literature offering a group-based analysis and examined it through the lens of the social identity approach (SIA). Founded in the insight that group memberships form an important part of the self-concept, the SIA encompasses five dimensions: social identity, social structure, identity content, strength of identification, and context. Findings Our search yielded 348 reports, 114 of which cited social identity. However, SIA-citing reports varied in both compatibility with the SIA's metatheoretical paradigm and applied relevance to health care; conversely, some non-SIA-citers offered SIA-congruent analyses. We analyzed the various combinations and interpretations of the five SIA dimensions, identifying ten major conceptual currents. Examining these in the light of the SIA yielded a cohesive, multifaceted picture of (inter)group relations in health care. Conclusions The SIA offers a coherent framework for integrating a diverse, far-flung literature on health care groups. Further research should take advantage of the full depth and complexity of the approach, remain sensitive to the unique features of the health care context, and devote particular attention to identity mobilization and context change as key drivers of system transformation. Our article concludes with a set of “guiding questions” to help health care leaders recognize the group dimension of organizational problems, identify mechanisms for change, and move forward by working with and through social identities, not against them.

[Dissociative identity disorder or schizophrenia?].  

PubMed

We present a case of dissociative identity disorder in which Schneiderian first rank symptoms were present besides of various states of consciousness. Thus the diagnosis of schizophrenia had to be considered. Formally, the symptoms met ICD-10 criteria for schizophrenia. However, taking into account the lack of formal thought disorder and of negative symptoms as well as a typical history of severe and prolonged traumatisation, we did not diagnose a co-morbid schizophrenic disorder. There is good evidence for the existence of psychotic symptoms among patients with dissociative disorders. However, in clinical practice this differential diagnosis is rarely considered.

Preferential flow penetration in a network of identical channels  

NASA Astrophysics Data System (ADS)

It is intuitive to expect a fluid to evenly penetrate two identical daughter channels supplied by the same source when these channels experience the same back pressure. In this work, we show that this might not be the case. We consider the displacement of one fluid by another in a network composed of two identical channels that linearly vary in radius. When surface tension is important, this simple shape variation can cause the fluid to primarily enter only one of the two branches, i.e., we find that the even or uniform fluid penetration into the network is not always stable. Displacement flows in small channels exhibit an interplay between viscous forces and capillary forces. We analyze the dynamics of our system, which features a hydrodynamic instability that is governed by the viscosities of the fluids, their wetting properties, the flow penetration speed, and the gradient characterizing the channel shape.

Identities, social representations and critical thinking  

NASA Astrophysics Data System (ADS)

This comment on L. Simonneaux and J. Simonneaux paper focuses on the role of identities in dealing with socio-scientific issues. We argue that there are two types of identities (social representations) influencing the students' positions: On the one hand their social representations of the bears' and wolves' identities as belonging to particular countries (Slovenia versus France for bears, France and Italy for wolves), in other words, as having national identities; on the other hand representations of their own identities as belonging to the field of agricultural practitioners, and so sharing this socio-professional identity with shepherds and breeders, as opposed to ecologists. We discuss how these representations of identities influenced students' reasoning and argumentation, blocking in some cases the evaluation of evidence. Implications for developing critical thinking and for dealing with SSI in the classrooms are outlined.

Social identity framing: Leader communication for social change  

NASA Astrophysics Data System (ADS)

Social identity framing (SIF) delineates a process of intergroup communication that leaders may engage in to promote a vision of social change. As a step towards social change, social identity may need to be altered to accommodate a new view of the group, its collective goals, and its place alongside other groups. Thus, social identity content may be deconstructed and reconstructed by the leader en route to change. SIF suggests that this may be achieved through a series of 16 communication tactics, which are largely derived from previous research (Seyranian & Bligh, 2008). This research used an experimental design to test the effectiveness of three SIF communication tactics - inclusion, similarity to followers, and positive social identity - on a number of follower outcomes. Students ( N=246) were randomly assigned to read one of eight possible speeches promoting renewable energy on campus that was ostensibly from a student leader. The speeches were varied to include or exclude the three communication tactics. Following the speech, participants completed a dependent measures questionnaire. Results indicated that similarity to followers and positive social identity did not affect follower outcomes. However, students exposed to inclusion were more likely to indicate that renewable energy was ingroup normative; intend to engage in collective action to bring renewable energy to campus; experience positive emotional reactions towards change; feel more confident about the possibility of change; and to view the leader more positively. The combination of inclusion and positive social identity increased perceptions of charismatic leadership. Perceived leader prototypicality and cognitive elaboration of the leader's message resulted in more favorable attitudes towards renewable energy. Perceived leader prototypicality was also directly related to social identification, environmental values, ingroup injunctive norms, and self-stereotypes. Overall, these results support SIF theory by providing evidence that communication that implicates social identity (i.e., inclusion) is an important aspect of the leader-follower influence process and that it can be used to bring about changes such as promoting environmental conservation policies. Avenues of future research on SIF are discussed.

Assessment of identity development and identity diffusion in adolescence - Theoretical basis and psychometric properties of the self-report questionnaire AIDA  

PubMed Central

Background In the continuing revision of Diagnostic and Statistical Manual (DSM-V) “identity” is integrated as a central diagnostic criterion for personality disorders (self-related personality functioning). According to Kernberg, identity diffusion is one of the core elements of borderline personality organization. As there is no elaborated self-rating inventory to assess identity development in healthy and disturbed adolescents, we developed the AIDA (Assessment of Identity Development in Adolescence) questionnaire to assess this complex dimension, varying from “Identity Integration” to “Identity Diffusion”, in a broad and substructured way and evaluated its psychometric properties in a mixed school and clinical sample. Methods Test construction was deductive, referring to psychodynamic as well as social-cognitive theories, and led to a special item pool, with consideration for clarity and ease of comprehension. Participants were 305 students aged 12–18 attending a public school and 52 adolescent psychiatric inpatients and outpatients with diagnoses of personality disorders (N?=?20) or other mental disorders (N?=?32). Convergent validity was evaluated by covariations with personality development (JTCI 12–18 R scales), criterion validity by differences in identity development (AIDA scales) between patients and controls. Results AIDA showed excellent total score (Diffusion: ??=?.94), scale (Discontinuity: ??=?.86; Incoherence: ??=?.92) and subscale (??=?.73-.86) reliabilities. High levels of Discontinuity and Incoherence were associated with low levels in Self Directedness, an indicator of maladaptive personality functioning. Both AIDA scales were significantly different between PD-patients and controls with remarkable effect sizes (d) of 2.17 and 1.94 standard deviations. Conclusion AIDA is a reliable and valid instrument to assess normal and disturbed identity in adolescents. Studies for further validation and for obtaining population norms are in progress and may provide insight in the relevant aspects of identity development in differentiating specific psychopathology and therapeutic focus and outcome.

Dissociative identity disorder: Medicolegal challenges.  

PubMed

Persons with dissociative identity disorder (DID) often present in the criminal justice system rather than the mental health system and perplex experts in both professions. DID is a controversial diagnosis with important medicolegal implications. Defendants have claimed that they committed serious crimes, including rape or murder, while they were in a dissociated state. Asserting that their alter personality committed the bad act, defendants have pleaded not guilty by reason of insanity (NGRI). In such instances, forensic experts are asked to assess the defendant for DID and provide testimony in court. Debate continues over whether DID truly exists, whether expert testimony should be allowed into evidence, and whether it should exculpate defendants for their criminal acts. This article reviews historical and theoretical perspectives on DID, presents cases that illustrate the legal implications and controversies of raising an insanity defense based on multiple personalities, and examines the role of forensic experts asked to comment on DID with the goal of assisting clinicians in the medicolegal assessment of DID in relation to crimes.

Fingerprint Recognition with Identical Twin Fingerprints  

PubMed Central

Fingerprint recognition with identical twins is a challenging task due to the closest genetics-based relationship existing in the identical twins. Several pioneers have analyzed the similarity between twins' fingerprints. In this work we continue to investigate the topic of the similarity of identical twin fingerprints. Our study was tested based on a large identical twin fingerprint database that contains 83 twin pairs, 4 fingers per individual and six impressions per finger: 3984 (83*2*4*6) images. Compared to the previous work, our contributions are summarized as follows: (1) Two state-of-the-art fingerprint identification methods: P071 and VeriFinger 6.1 were used, rather than one fingerprint identification method in previous studies. (2) Six impressions per finger were captured, rather than just one impression, which makes the genuine distribution of matching scores more realistic. (3) A larger sample (83 pairs) was collected. (4) A novel statistical analysis, which aims at showing the probability distribution of the fingerprint types for the corresponding fingers of identical twins which have same fingerprint type, has been conducted. (5) A novel analysis, which aims at showing which finger from identical twins has higher probability of having same fingerprint type, has been conducted. Our results showed that: (a) A state-of-the-art automatic fingerprint verification system can distinguish identical twins without drastic degradation in performance. (b) The chance that the fingerprints have the same type from identical twins is 0.7440, comparing to 0.3215 from non-identical twins. (c) For the corresponding fingers of identical twins which have same fingerprint type, the probability distribution of five major fingerprint types is similar to the probability distribution for all the fingers' fingerprint type. (d) For each of four fingers of identical twins, the probability of having same fingerprint type is similar. PMID:22558204

Changing institutional identities of the student nurse.  

PubMed

This paper emphasises the tensions between the ideal of the compliant within care settings and the ideal of the critical thinker within the university setting with reference to student nurse education and identity. Identity is an important part of who we are as people. While modernisation and increased professionalisation of nursing have impacted on staff and patients mostly in a positive way, changes in the management of nursing education in the past 20 years have also heralded a remarkable change in the student identity. Historically informed by association with a particular hospital or health service provider, student nurse identity was shaped by institutional rituals and routine, physically embodied in objects such as uniforms and hospital medals and informed by claims to honesty, virtue and personal integrity (Bradby, 1990). Once part of the structure and fabric of hospital life, nursing students functioned as part of the health care service. As such, their identity was synonymous with that of practicing nurses, whose learning needs were secondary to that of the organisational needs. While this social milieu provided the platform for the formation of institutional pride, belonging and identity, such forms of identity can result in institutional compliance; with the associated risk of ritualistic practice, poor levels of transparent accountability and barriers to whistle blowing should substandard practice arise. Increased student freedom and an emphasis on teaching and learning within the university setting may have benefitted students, patients and the profession, however, the potential impact on student identity is less certain. There is evidence to suggest that students are ill-equipped for their professional identity once qualified and thus require more support for this within universities. This paper explores the tensions between traditional hospital identity and contemporary university identity with reference to student nurse education. The ideal of the compliant versus the ideal of the critical thinker will be debated. PMID:22795742

Vocal caricatures reveal signatures of speaker identity  

NASA Astrophysics Data System (ADS)

What are the features that impersonators select to elicit a speaker's identity? We built a voice database of public figures (targets) and imitations produced by professional impersonators. They produced one imitation based on their memory of the target (caricature) and another one after listening to the target audio (replica). A set of naive participants then judged identity and similarity of pairs of voices. Identity was better evoked by the caricatures and replicas were perceived to be closer to the targets in terms of voice similarity. We used this data to map relevant acoustic dimensions for each task. Our results indicate that speaker identity is mainly associated with vocal tract features, while perception of voice similarity is related to vocal folds parameters. We therefore show the way in which acoustic caricatures emphasize identity features at the cost of loosing similarity, which allows drawing an analogy with caricatures in the visual space.

Continuous identity authentication using multimodal physiological sensors  

NASA Astrophysics Data System (ADS)

This paper on multi-modal continuous identity authentication contains four main sections. The first section describes the security issue we are addressing with the use of continuous identity authentication and describes the research our laboratory has been doing with different types of passive physiological sensors and how the multi-modal sensor data can be applied to continuous identity authentication. The second section describes a pilot study measuring temperature, GSR, eye movement, blood flow and click pressure of thirteen subjects performing a computer task. The third section gives preliminary results that show continuous authentication of identity above 80 percent was possible using discriminant analysis with a limited set of all of the measures for all but two subjects. The fourth section discusses the results and the potential of continuous identity authentication.

Identity-based motivation: Implications for intervention  

PubMed Central

Children want to succeed academically and attend college, but their actual attainment often lags behind; some groups (e.g., boys, low-income children) are particularly likely to experience this gap. Social structural factors matter, influencing this gap in part by affecting children's perceptions of what is possible for them and people like them in the future. Interventions that focus on this macro-micro interface can boost children's attainment. We articulate the processes underlying these effects using an integrative culturally sensitive framework entitled identity-based motivation (IBM, Oyserman, 2007, 2009a, 2009b). The IBM model assumes that identities are dynamically constructed in context. People interpret situations and difficulties in ways that are congruent with currently active identities and prefer identity-congruent to identity-incongruent actions. When action feels identity-congruent, experienced difficulty highlights that the behavior is important and meaningful. When action feels identity-incongruent, the same difficulty suggests that the behavior is pointless and “not for people like me.” PMID:21516204

Ethnic identity of older Chinese in Canada.  

PubMed

In Canada's multicultural society, ethnic identity is important to the elderly and can influence areas such as access to services, health promotion and care. Often, the complex nature of ethnic identity is underestimated when looking at cultural groups. This study aims to: (a) validate the factor structure of a Chinese ethnic identity measure for older Chinese in Canada, (b) examine the level of ethnic identity of the participants, and (c) examine the correlates of ethnic identity in these older individuals. Using data from a large, national research project on the elderly Chinese in Canada, this study analyzed the results gathered from a total of 2,272 participants. Principal component analysis, maximum-likelihood confirmatory factor analysis, and multiple regression analysis were performed. The results indicated that ethnic identity of the older Chinese is a multi-dimensional construct made up of three factors: (a) culture related activities, (b) community ties, (c) linkage with country of origin, and (d) cultural identification. The findings have provided a better understanding of how ethnic identity can be measured among the aging Chinese population in Canada. PMID:22198551

Transfer of newly acquired stimulus valence between identities in dissociative identity disorder (DID).  

PubMed

Patients with Dissociative Identity Disorder (DID) frequently report episodes of interidentity amnesia, that is amnesia for events experienced by other identities. The goal of the present experiment was to test the implicit transfer of trauma-related information between identities in DID. We hypothesized that whereas declarative information may transfer from one identity to another, the emotional connotation of the memory may be dissociated, especially in the case of negative, trauma-related emotional valence. An evaluative conditioning procedure was combined with an affective priming procedure, both performed by different identities. In the evaluative conditioning procedure, previously neutral stimuli come to refer to a negative or positive connotation. The affective priming procedure was used to test the transfer of this acquired valence to an identity reporting interidentity amnesia. Results indicated activation of stimulus valence in the affective priming task, that is transfer of emotional material between identities. PMID:15629753

Double-smoothing for Varying Coefficient Models  

PubMed Central

Moderation analyses are widely used in biomedical and psychosocial research to investigate differential treatment effects, with moderators frequently identified through testing the significance of the interaction between the predictor and the potential moderator under strong parametric assumptions. Without imposing any parametric forms on how the moderators may affect the relationship between predictors and responses, varying coefficient models address this fundamental problem of strong parametric assumptions with current practice of moderation analysis and provide a much broader class of models for complex moderation relationships. Local polynomial, especially local linear, methods are commonly used in estimating the varying coefficient models. Recently, a double-smoothing (DS) local linear method has been proposed for nonparametric regression models, with nice properties compared to local linear and local cubic methods. In this paper, we generalize DS to varying coefficient models, and show that it holds similar advantages over local linear and local cubic methods. PMID:22121327

Negotiating identity: a qualitative analysis of stigma and support seeking for individuals with cerebral palsy.  

PubMed

Abstract Purpose: The current research investigates how adults with cerebral palsy construct their personal and social identities in the face of stigma when support seeking, and considers the dilemmas they might face when doing so. Method: Participants were 28 adults with cerebral palsy who completed an online survey reporting on their identity as a person with cerebral palsy and their experiences of stigma when seeking and accessing support. Results: Qualitative analyses indicated that the majority of participants sought support to help manage their cerebral palsy. Of these, half reported experiencing stigma in these environments, although they largely continued seeking support despite this. The majority viewed both their personal identity (i.e. as a unique individual) and their social identity (i.e. as a person with cerebral palsy) as important to their sense of self. However, how participants constructed their identity also appeared to vary according to context. While they appeared to value being seen as an individual to receive support that was unique to their needs (their personal identity), they also reported valuing the group to facilitate coping with stigma (their social identity). Yet, despite their utilities, enacting their identity in each of these ways was associated with costs. In order to access desired support, they had to incorporate their social identity as similar to other disabled people, which led to stigmatization through feelings of difference to the non-disabled. Conversely emphasizing individuality and difference from the disabled stereotype was associated with concerns about the degree to which their suitability for support might be questioned by their care provider. Conclusions: As has been observed in many fields, stigma can complicate identity. In this domain, people with cerebral palsy face a number of threats in how they construe their identity, both in navigating stigma and maintaining access to needed support. Implications for Rehabilitation Stigma in help and support settings remains a significant problem for adults with cerebral palsy (CP). This creates dilemmas regarding how they view and construct their identity in the contexts of stigma and support-seeking. It is important for specialists to recognize that the needs of adults with CP are unique, and so provided services should be tailored to the individual. Healthcare providers should also encourage their patients to actively engage with online disability support groups in order to build a meaningful social identity with other people with CP.

Regularizing cosmological singularities by varying physical constants  

SciTech Connect

Varying physical constant cosmologies were claimed to solve standard cosmological problems such as the horizon, the flatness and the ?-problem. In this paper, we suggest yet another possible application of these theories: solving the singularity problem. By specifying some examples we show that various cosmological singularities may be regularized provided the physical constants evolve in time in an appropriate way.

Objective We investigated whether there is a positive, unique relation between smoker identity and smoking escalation. Methods Adolescents from the Chicago area (n = 1263) completed paper-and-pencil questionnaires and in-person interviews at baseline, 6 months, 15 months, and 24 months of a longitudinal study. Smoking behavior, smoker identity, nicotine dependence, smoking expectancies, smoking motives, and novelty seeking were assessed. Results There was a unique relation between smoker identity and smoking escalation. The more that adolescents thought smoking was a defining aspect of who they were, the more likely their smoking escalated. Conclusions The findings suggest that smoker identity could be targeted for preventing escalation. Research on its development is needed. PMID:22775236

Identity Representations of People With Diabetes.  

PubMed

In this study, we aimed to investigate the construction of identity representations by primary health care patients with type 2 diabetes mellitus and their relationship to the required self-care actions. A free word association technique required clients from a basic health unit (N = 34) to suggest a word or expression and justify it in response to the question, "When talking about being a diabetic, what comes to your mind?" We performed, transcribed, and categorized the recordings, then interpreted them according to thematic content analysis, social representation, and social identity theories. Intentions mediated by identity processes-social comparison, social attribution, and categorization within the studied group-and also by objectification and anchoring, provided the following social constructions: normal, accepting of the disease, feeling unaccepting, and experiencing difficulties. The disease might alter patients' identity representation within a context permeated by individuals' subjective sense. PMID:24970248

Components in time-varying graphs  

NASA Astrophysics Data System (ADS)

Real complex systems are inherently time-varying. Thanks to new communication systems and novel technologies, today it is possible to produce and analyze social and biological networks with detailed information on the time of occurrence and duration of each link. However, standard graph metrics introduced so far in complex network theory are mainly suited for static graphs, i.e., graphs in which the links do not change over time, or graphs built from time-varying systems by aggregating all the links as if they were concurrent in time. In this paper, we extend the notion of connectedness, and the definitions of node and graph components, to the case of time-varying graphs, which are represented as time-ordered sequences of graphs defined over a fixed set of nodes. We show that the problem of finding strongly connected components in a time-varying graph can be mapped into the problem of discovering the maximal-cliques in an opportunely constructed static graph, which we name the affine graph. It is, therefore, an NP-complete problem. As a practical example, we have performed a temporal component analysis of time-varying graphs constructed from three data sets of human interactions. The results show that taking time into account in the definition of graph components allows to capture important features of real systems. In particular, we observe a large variability in the size of node temporal in- and out-components. This is due to intrinsic fluctuations in the activity patterns of individuals, which cannot be detected by static graph analysis.

Student Engineers and Engineer Identity: Campus Engineer Identities as Figured World  

NASA Astrophysics Data System (ADS)

The research reported here contributes to understanding how student engineers on an engineering campus in the US mid-continent not only talked about the kinds of people recognized as engineers on campus, but also juxtaposes their talk about "campus engineer identities" with two students' ways of presenting themselves as engineers through engineering project teamwork to argue that campus engineer identities framed on-campus interpretations of actions, and ultimately that identity production was a complicated process through which campus engineer identities (cultural knowledge learned on campus) provided a lens of meaning through which to "recognize" (or not) performances of engineer selves as engineers. This research adds to conversations about identity in practice, especially identity production in science education, by suggesting the importance of cultural forms for belonging, especially at an obdurate site of science practice like the campus studied.

Converging identities: dimensions of acculturation and personal identity status among immigrant college students.  

PubMed

The present study was designed to ascertain the extent to which dimensions of acculturation would differ across personal identity statuses in a sample of 2,411 first- and second-generation, immigrant, college-attending emerging adults. Participants from 30 colleges and universities around the United States completed measures of personal identity processes, as well as of heritage and American cultural practices, values, and identifications. Cluster-analytic procedures were used to classify participants into personal identity statuses based on the personal identity processes. Results indicated that, across ethnic groups, individuals in the achieved and searching moratorium statuses reported the greatest endorsement of heritage and American cultural practices, values, and identifications; and individuals in the carefree diffusion status reported the lowest endorsement of all the cultural variables under study. These results are discussed in terms of the convergence between personal identity and cultural identity processes. PMID:23148900

When moral identity symbolization motivates prosocial behavior: the role of recognition and moral identity internalization.  

PubMed

This article examines the role of moral identity symbolization in motivating prosocial behaviors. We propose a 3-way interaction of moral identity symbolization, internalization, and recognition to predict prosocial behavior. When moral identity internalization is low, we hypothesize that high moral identity symbolization motivates recognized prosocial behavior due to the opportunity to present one's moral characteristics to others. In contrast, when moral identity internalization is high, prosocial behavior is motivated irrespective of the level of symbolization and recognition. Two studies provide support for this pattern examining volunteering of time. Our results provide a framework for predicting prosocial behavior by combining the 2 dimensions of moral identity with the situational factor of recognition. PMID:23751218

List A was shown to one identity, while list B was shown to another identity claiming total amnesia for the words learned by the first identity. The identity claiming amnesia was tested for intrusions from list A words into the recall of words from list B and recognition of the words learned by both identities. Test results indicated no evidence of total interidentity amnesia for emotionally valenced material in DID. It is argued that dissociative amnesia in DID may more adequately be described as a disturbance in meta-memory functioning instead of an actual retrieval inability. PMID:16928360

Nonlinear deterministic modeling of highly varying loads  

SciTech Connect

Typically, the modeling of highly varying, nonlinear loads such as electric arc furnaces has involved stochastic techniques. This paper presents the use of chaotic dynamics to describe the operation of nonlinear loads. Included is a discussion of the Lyapunov exponents, a measure of chaotic behavior. The alternate approach is applied to electric arc furnaces. A tuning mode is described to develop the parameters of a chaotic model. This model is trained to have time and frequency responses that are tuned to match the current from the arc furnace under study. The simulated data are compared to actual arc furnace data to validate the model. This model is used to assess the impact of various highly varying nonlinear loads that exhibit chaos in power systems.

Soliton interaction with slowly varying potentials  

E-print Network

We study the Gross-Pitaevskii equation with a slowly varying smooth potential, $V(x) = W(hx)$. We show that up to time $\\log(1/h)/h $ and errors of size $h^2$ in $H^1$, the solution is a soliton evolving according to the classical dynamics of a natural effective Hamiltonian, $ (\\xi^2 + \\sech^2 * V (x))/2 $. This provides an improvement ($ h \\to h^2 $) compared to previous works, and is strikingly confirmed by numerical simulations.

Serum Sclerostin Levels Vary With Season  

PubMed Central

Context: To establish the clinical utility of serum sclerostin levels, it is important to know whether there is seasonal variation in the measurements. Objective: This study was done to determine whether serum sclerostin levels vary by season in healthy older men and women. Methods: Serum sclerostin levels were measured in archived serum of 314 healthy men and women aged 65 years and older and examined for seasonal variation. Several factors known to vary by season and previously reported to be associated with serum sclerostin levels, including serum osteocalcin, physical activity, and serum PTH levels, were also measured in these subjects. Sex did not modify the association of season with sclerostin, so the men and women were analyzed together. Results: Serum sclerostin levels varied significantly by season (P < .001, after adjustment for sex). Sclerostin levels in the wintertime were 20% higher than the all-year mean, the levels gradually declined through the spring and summer, and by the fall, they were 20% below the all-year mean. Adjustment for serum osteocalcin, physical activity, and serum PTH did not alter the seasonal means. Seasonal differences in serum osteocalcin, physical activity, and serum PTH were not statistically significant. Conclusions: This study documents marked seasonal variation in serum sclerostin levels. It is important to recognize this source of biological variability when considering the potential clinical utility of sclerostin measurements. PMID:24248178

Adaptive, template moderated, spatially varying statistical classification.  

PubMed

A novel image segmentation algorithm was developed to allow the automatic segmentation of both normal and abnormal anatomy from medical images. The new algorithm is a form of spatially varying statistical classification, in which an explicit anatomical template is used to moderate the segmentation obtained by statistical classification. The algorithm consists of an iterated sequence of spatially varying classification and nonlinear registration, which forms an adaptive, template moderated (ATM), spatially varying statistical classification (SVC). Classification methods and nonlinear registration methods are often complementary, both in the tasks where they succeed and in the tasks where they fail. By integrating these approaches the new algorithm avoids many of the disadvantages of each approach alone while exploiting the combination. The ATM SVC algorithm was applied to several segmentation problems, involving different image contrast mechanisms and different locations in the body. Segmentation and validation experiments were carried out for problems involving the quantification of normal anatomy (MRI of brains of neonates) and pathology of various types (MRI of patients with multiple sclerosis, MRI of patients with brain tumors, MRI of patients with damaged knee cartilage). In each case, the ATM SVC algorithm provided a better segmentation than statistical classification or elastic matching alone. PMID:10972320

The structure of ethnic attitudes: the effects of target group, region, gender, and national identity.  

PubMed

The present study was an assessment of attitudes of 410 ethnically Dutch adolescents toward three ethnic minority groups living in the Netherlands. Stereotypes, symbolic beliefs, affective associations, and the evaluation of possible interactions were used to predict the global evaluation of ethnic outgroups and accounted for much of the variance in ethnic attitudes. The relative importance of the four predictors varied by target group and location. Gender differences were found in the structure of attitudes; symbolic beliefs played a greater role in the attitudes of boys, whereas emotions played a more central role in the attitudes of girls. The evaluation of Dutch identity was related to the favorability of ethnic attitudes and also to the underlying structure. Respondents with a positive national identity had less favorable ethnic attitudes, and emotions were more predictive of their attitudes, whereas symbolic beliefs were most predictive among respondents with a less positive national identity.

Hemifield effects in multiple identity tracking.  

PubMed

In everyday life, we often need to attentively track moving objects. A previous study has claimed that this tracking occurs independently in the left and right visual hemifields (Alvarez & Cavanagh, 2005, Psychological Science,16, 637-647). Specifically, it was shown that observers were much more accurate at tracking objects that were spread over both visual hemifields as opposed to when all were confined to a single visual hemifield. In that study, observers were not required to remember the identities of the objects. Conversely, in real life, there is seldom any benefit to tracking an object unless you can also recall its identity. It has been predicted that when observers are required to remember the identities of the tracked objects a bilateral advantage should no longer be observed (Oksama & Hyönä, 2008, Cognitive Psychology, 56, 237-283). We tested this prediction and found that a bilateral advantage still occurred, though it was not as strong as when observers were not required to remember the identities of the targets. Even in the later case we found that tracking was not completely independent in the two visual hemifields. We present a combined model of multiple object tracking and multiple identity tracking that can explain our data. PMID:22952767

Interidentity memory transfer in dissociative identity disorder.  

PubMed

Controversy surrounding dissociative identity disorder (DID) has focused on conflicting findings regarding the validity and nature of interidentity amnesia, illustrating the need for objective methods of examining amnesia that can discriminate between explicit and implicit memory transfer. In the present study, the authors used a cross-modal manipulation designed to mitigate implicit memory effects. Explicit memory transfer between identities was examined in 7 DID participants and 34 matched control participants. After words were presented to one identity auditorily, the authors tested another identity for memory of those words in the visual modality using an exclusion paradigm. Despite self-reported interidentity amnesia, memory for experimental stimuli transferred between identities. DID patients showed no superior ability to compartmentalize information, as would be expected with interidentity amnesia. The cross-modal nature of the test makes it unlikely that memory transfer was implicit. These findings demonstrate that subjective reports of interidentity amnesia are not necessarily corroborated by objective tests of explicit memory transfer. PMID:18729620

Linear Parameter Varying Control for Actuator Failure  

NASA Technical Reports Server (NTRS)

A robust linear parameter varying (LPV) control synthesis is carried out for an HiMAT vehicle subject to loss of control effectiveness. The scheduling parameter is selected to be a function of the estimates of the control effectiveness factors. The estimates are provided on-line by a two-stage Kalman estimator. The inherent conservatism of the LPV design is reducing through the use of a scaling factor on the uncertainty block that represents the estimation errors of the effectiveness factors. Simulations of the controlled system with the on-line estimator show that a superior fault-tolerance can be achieved.

Osteosarcoma is the most common primary malignant tumor of the skeleton involving predominantly metaphysis of the long bones. Diaphyseal osteosarcoma is a rare form, which accounts for approximately 10% of all cases of osteosarcomas. Osteosarcoma contains a family of lesions with considerable diversity in histologic features and grade. We present a case of a 29-year-old male with diaphyseal osteosarcoma of the left tibia, who presented with pain and swelling over middle one-third of the left leg. The biopsy of the lesion revealed varied histomorphologic features in a small tissue studied. This prompted us to report the various histologic patterns of osteosarcoma. PMID:24600604

Identity and civic engagement in adolescence.  

PubMed

The purpose of this study was to examine the links between identity (statuses and processes) and adolescent civic engagement (volunteer and political participation). Participants were 392 Italian high school students (42% males) aged 14-20 years (M(age) = 16.23 years; SD(age) = 1.53) who completed a self-report questionnaire. First, using a person-centered approach, we found that achieved adolescents were more involved in volunteer activities, reported higher civic efficacy, and stronger aspirations to contribute to their communities than their diffused counterparts. Second, by means of a variable-centered approach, we demonstrated that the link between identity processes (i.e., commitment and in-depth exploration) and past and future volunteer and political participation was mediated by social responsibility. Implications of the findings for current understanding of the link between adolescent identity formation and civic engagement are discussed and suggestions for future research are outlined.

Shared identity is key to effective communication.  

PubMed

The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication. PMID:25416042

Entanglement and particle identity: a unifying approach.  

PubMed

It has been known for some years that entanglement entropy obtained from partial trace does not provide the correct entanglement measure when applied to systems of identical particles. Several criteria have been proposed that have the drawback of being different according to whether one is dealing with fermions, bosons, or distinguishable particles. In this Letter, we give a precise and mathematically natural answer to this problem. Our approach is based on the use of the more general idea of the restriction of states to subalgebras. It leads to a novel approach to entanglement, which is suitable to be used in general quantum systems and especially in systems of identical particles. This settles some recent controversy regarding entanglement for identical particles. The prospects for applications of our criteria are wide ranging, from spin chains in condensed matter to entropy of black holes. PMID:23473123

SUSY Ward identities, superamplitudes and counterterms  

NASA Astrophysics Data System (ADS)

Ward identities of SUSY and R-symmetry relate n-point amplitudes in supersymmetric theories. We review recent work in which these Ward identities are solved in {\\cal N}=4 SYM and {\\cal N}=8 supergravity. The solution, valid at both tree and loop level, expresses any NKMHV superamplitude in terms of a basis of ordinary amplitudes. Basis amplitudes are classified by semi-standard tableaux of rectangular {\\cal N}×K Young diagrams. The SUSY Ward identities also impose constraints on the matrix elements of candidate ultraviolet counterterms in {\\cal N}=8 supergravity, and they can be studied using superamplitude basis expansions. This leads to a novel and quite comprehensive matrix element approach to counterterms, which we also review. This article is an invited review for a special issue of Journal of Physics A: Mathematical and Theoretical devoted to 'Scattering amplitudes in gauge theories'.

Ratings of Essentialism for Eight Religious Identities  

PubMed Central

As a social identity, religion is unique because it contains a spectrum of choice. In some religious communities, individuals are considered members by virtue of having parents of that background, and religion, culture, and ethnicity are closely intertwined. Other faith communities actively invite people of other backgrounds to join, expecting individuals to choose the religion that best fits their personal beliefs. These various methods of identification influence beliefs about the essentialist nature of religious identity. Essentialism is when social groups are considered to have deep, immutable, and inherent defining properties. In this study, college students (N=55) provided ratings of essentialism for eight religious identities: Atheist, Buddhist, Catholic, Hindu, Jewish, Muslim, Protestant, and Spiritual-but-not-religious. Significant differences in essentialism were found between the target groups. Results and implications for intergroup relations are discussed. PMID:21572550

Toroidal Varied-Line Space (TVLS) Gratings  

NASA Technical Reports Server (NTRS)

It is a particular challenge to develop a stigmatic spectrograph for XUV wavelengths since the very low normal-incidence reflectance of standard materials most often requires that the design be restricted to a single optical element which must simultaneously provide both re-imaging and spectral dispersion. This problem has been solved in the past by the use of toroidal gratings with uniform line-spaced rulings (TULS). A number of solar EUV (Extreme Ultraviolet) spectrometers have been based on such designs, including SOHO/CDS, Solar-B/EIS, and the sounding rockets SERTS and EUNIS. More recently, Kita, Harada, and collaborators have developed the theory of spherical gratings with varied line-space rulings (SVLS) operated at unity magnification, which have been flown on several astronomical satellite missions. We now combine these ideas into a spectrometer concept that puts varied-line space rulings onto toroidal gratings. Such TVLS designs are found to provide excellent imaging even at very large spectrograph magnifications and beam-speeds, permitting extremely high-quality performance in remarkably compact instrument packages. Optical characteristics of two solar spectrometers based on this concept are described: SUMI, proposed as a sounding rocket experiment, and NEXUS, proposed for the Solar Dynamics Observatory mission.

Varying execution discipline to increase performance  

SciTech Connect

This research investigates the relationship between execution discipline and performance. The hypothesis has two parts: 1. Different execution disciplines exhibit different performance for different computations, and 2. These differences can be effectively predicted by heuristics. A machine model is developed that can vary its execution discipline. That is, the model can execute a given program using either the control-driven, data-driven or demand-driven execution discipline. This model is referred to as a ``variable-execution-discipline`` machine. The instruction set for the model is the Program Dependence Web (PDW). The first part of the hypothesis will be tested by simulating the execution of the machine model on a suite of computations, based on the Livermore Fortran Kernel (LFK) Test (a.k.a. the Livermore Loops), using all three execution disciplines. Heuristics are developed to predict relative performance. These heuristics predict (a) the execution time under each discipline for one iteration of each loop and (b) the number of iterations taken by that loop; then the heuristics use those predictions to develop a prediction for the execution of the entire loop. Similar calculations are performed for branch statements. The second part of the hypothesis will be tested by comparing the results of the simulated execution with the predictions produced by the heuristics. If the hypothesis is supported, then the door is open for the development of machines that can vary execution discipline to increase performance.

Effects of species evenness and dominant species identity on multiple ecosystem functions in model grassland communities.  

PubMed

Ecosystems provide multiple services upon which humans depend. Understanding the drivers of the ecosystem functions that support these services is therefore important. Much research has investigated how species richness influences functioning, but we lack knowledge of how other community attributes affect ecosystem functioning. Species evenness, species spatial arrangement, and the identity of dominant species are three attributes that could affect ecosystem functioning, by altering the relative abundance of functional traits and the probability of synergistic species interactions such as facilitation and complementary resource use. We tested the effect of these three community attributes and their interactions on ecosystem functions over a growing season, using model grassland communities consisting of three plant species from three functional groups: a grass (Anthoxanthum odoratum), a forb (Plantago lanceolata), and a N-fixing forb (Lotus corniculatus). We measured multiple ecosystem functions that support ecosystem services, including ecosystem gas exchange, water retention, C and N loss in leachates, and plant biomass production. Species evenness and dominant species identity strongly influenced the ecosystem functions measured, but spatial arrangement had few effects. By the end of the growing season, evenness consistently enhanced ecosystem functioning and this effect occurred regardless of dominant species identity. The identity of the dominant species under which the highest level of functioning was attained varied across the growing season. Spatial arrangement had the weakest effect on functioning, but interacted with dominant species identity to affect some functions. Our results highlight the importance of understanding the role of multiple community attributes in driving ecosystem functioning. PMID:24213721

Synchronization analysis of delayed complex networks via adaptive time-varying coupling strengths  

NASA Astrophysics Data System (ADS)

In this Letter, we study the synchronization for delayed complex networks by adjusting time-varying coupling strengths. Under some assumptions, the update laws of the coupling strengths are obtained to realize the synchronization based on Lassalle-Yoshizawa theorem. For the given delayed complex network, we can always find appropriate coupling strengths to achieve the synchronization. Compared with the existing results, the update laws don't need the information of the characteristics of the identical node and the coupling matrix. The state-dependencies of coupling strengths coupled to the dynamics of the nodes in a way to enhance synchronization. An example shows the proposed theoretical result is feasible and effective.

Identity Management in Agent Systems1  

Microsoft Academic Search

Agent technology is a promising and enabling technology in open distributed environments. Agents are autonomous entities that interact with each other and with (web-) services, for which digital identity management (DIDM) is a prerequisite: the rights and obligations of all entities in an agent system need to be secured. A framework for evaluation of DIDM in agent systems is proposed.

Returning forests analyzed with the forest identity  

PubMed Central

Amid widespread reports of deforestation, some nations have nevertheless experienced transitions from deforestation to reforestation. In a causal relationship, the Forest Identity relates the carbon sequestered in forests to the changing variables of national or regional forest area, growing stock density per area, biomass per growing stock volume, and carbon concentration in the biomass. It quantifies the sources of change of a nation's forests. The Identity also logically relates the quantitative impact on forest expanse of shifting timber harvest to regions and plantations where density grows faster. Among 50 nations with extensive forests reported in the Food and Agriculture Organization's comprehensive Global Forest Resources Assessment 2005, no nation where annual per capita gross domestic product exceeded $4,600 had a negative rate of growing stock change. Using the Forest Identity and national data from the Assessment report, a single synoptic chart arrays the 50 nations with coordinates of the rates of change of basic variables, reveals both clusters of nations and outliers, and suggests trends in returning forests and their attributes. The Forest Identity also could serve as a tool for setting forest goals and illuminating how national policies accelerate or retard the forest transitions that are diffusing among nations.

Seeking new identity through the empowerment process  

PubMed Central

Background: All health professionals are responsible for facilitating empowerment among people with diabetes. However, research suggests that health professionals do not have the knowledge and skills to help people with diabetes become empowered. As a result, many Iranian people with diabetes do not become empowered. The aim of the study was to explore and understand how empowerment occurs in Iranian people with diabetes. Materials and Methods: Grounded theory using individual open in-depth interviews, field notes, and memos was used to collect data from 25 people with diabetes, their families, and health professionals. Strauss and Corbin's constant comparative analysis was used to analyze the data. Findings: Empowerment is a transitional, perceptual, and continuous process. The process for people with diabetes includes threatened identity when diabetes is diagnosed, reconstructing identity, and integrating diabetes into identity to become an empowered person with diabetes. The empowerment process was influenced by a combination of knowledge, social support, values and beliefs, psychosocial issues, and the nature of diabetes. Conclusions: Health professionals can help people with diabetes integrate diabetes into their identity and become empowered; however, becoming empowered is complicated and occurs over time.

Autobiographical memory specificity in dissociative identity disorder.  

PubMed

A lack of adequate access to autobiographical knowledge has been related to psychopathology. More specifically, patients suffering from depression or a history of trauma have been found to be characterized by overgeneral memory, in other words, they show a relative difficulty in retrieving a specific event from memory located in time and place. Previous studies of overgeneral memory have not included patients with dissociative disorders. These patients are interesting to consider, as they are hypothesized to have the ability to selectively compartmentalize information linked to negative emotions. This study examined avoidance and overgeneral memory in patients with dissociative identity disorder (DID; n = 12). The patients completed the autobiographical memory test (AMT). Their performance was compared with control groups of posttraumatic stress disorder (PTSD) patients (n = 26), healthy controls (n = 29), and DID simulators (n = 26). Specifically, we compared the performance of separate identity states in DID hypothesized to diverge in the use of avoidance as a coping strategy to deal with negative affect. No significant differences in memory specificity were found between the separate identities in DID. Irrespective of identity state, DID patients were characterized by a lack of memory specificity, which was similar to the lack of memory specificity found in PTSD patients. The converging results for DID and PTSD patients add empirical evidence for the role of overgeneral memory involved in the maintenance of posttraumatic psychopathology. PMID:24886016

Contextuality is about identity of random variables  

NASA Astrophysics Data System (ADS)

Contextual situations are those in which seemingly ‘the same’ random variable changes its identity depending on the conditions under which it is recorded. Such a change of identity is observed whenever the assumption that the variable is one and the same under different conditions leads to contradictions when one considers its joint distribution with other random variables (this is the essence of all Bell-type theorems). In our Contextuality-by-Default approach, instead of asking why or how the conditions force ‘one and the same’ random variable to change ‘its’ identity, any two random variables recorded under different conditions are considered different ‘automatically.’ They are never the same, nor are they jointly distributed, but one can always impose on them a joint distribution (probabilistic coupling). The special situations when there is a coupling in which these random variables are equal with probability 1 are considered noncontextual. Contextuality means that such couplings do not exist. We argue that the determination of the identity of random variables by conditions under which they are recorded is not a causal relationship and cannot violate laws of physics.

TDR Using Autocorrelation and Varying-Duration Pulses  

NASA Technical Reports Server (NTRS)

In an alternative to a prior technique of time-domain-reflectometry (TDR) in which very short excitation pulses are used, the pulses have very short rise and fall times and the pulse duration is varied continuously between a minimum and a maximum value. In both the present and prior techniques, the basic idea is to (1) measure the times between the generation of excitation pulses and the reception of reflections of the pulses as indications of the locations of one or more defects along a cable and (2) measure the amplitudes of the reflections as indication of the magnitudes of the defects. In general, an excitation pulse has a duration T. Each leading and trailing edge of an excitation pulse generates a reflection from a defect, so that a unique pair of reflections is associated with each defect. In the present alternative technique, the processing of the measured reflection signal includes computation of the autocorrelation function R(tau) identical with fx(t)x(t-tau)dt where t is time, x(t) is the measured reflection signal at time t, and taus is the correlation interval. The integration is performed over a measurement time interval short enough to enable identification and location of a defect within the corresponding spatial interval along the cable. Typically, where there is a defect, R(tau) exhibits a negative peak having maximum magnitude for tau in the vicinity of T. This peak can be used as a means of identifying a leading-edge/trailing-edge reflection pair. For a given spatial interval, measurements are made and R(tau) computed, as described above, for pulse durations T ranging from the minimum to the maximum value. The advantage of doing this is that the effective signal-to-noise ratio may be significantly increased over that attainable by use of a fixed pulse duration T.

Dissociable Neural Patterns of Facial Identity across Changes in Viewpoint  

Microsoft Academic Search

We examined the neural response patterns for facial identity independent of viewpoint and for viewpoint independent of identity. Neural activation patterns for identity and viewpoint were collected in an fMRI experiment. Faces appeared in identity-constant blocks, with variable viewpoint, and in viewpoint-constant blocks, with variable identity. Pattern-based classifiers were used to discriminate neural response patterns for all possible pairs of

Time varying, multivariate volume data reduction  

SciTech Connect

Large-scale supercomputing is revolutionizing the way science is conducted. A growing challenge, however, is understanding the massive quantities of data produced by large-scale simulations. The data, typically time-varying, multivariate, and volumetric, can occupy from hundreds of gigabytes to several terabytes of storage space. Transferring and processing volume data of such sizes is prohibitively expensive and resource intensive. Although it may not be possible to entirely alleviate these problems, data compression should be considered as part of a viable solution, especially when the primary means of data analysis is volume rendering. In this paper we present our study of multivariate compression, which exploits correlations among related variables, for volume rendering. Two configurations for multidimensional compression based on vector quantization are examined. We emphasize quality reconstruction and interactive rendering, which leads us to a solution using graphics hardware to perform on-the-fly decompression during rendering. In this paper we present a solution which addresses the need for data reduction in large supercomputing environments where data resulting from simulations occupies tremendous amounts of storage. Our solution employs a lossy encoding scheme to acrueve data reduction with several options in terms of rate-distortion behavior. We focus on encoding of multiple variables together, with optional compression in space and time. The compressed volumes can be rendered directly with commodity graphics cards at interactive frame rates and rendering quality similar to that of static volume renderers. Compression results using a multivariate time-varying data set indicate that encoding multiple variables results in acceptable performance in the case of spatial and temporal encoding as compared to independent compression of variables. The relative performance of spatial vs. temporal compression is data dependent, although temporal compression has the advantage of offering smooth animations, while spatial compression can handle volumes of larger dimensions.

Decomposing socioeconomic inequality for binary health outcomes: an improved estimation that does not vary by choice of reference group  

PubMed Central

Background Decomposition of concentration indices yields useful information regarding the relative importance of various determinants of inequitable health outcomes. But the two estimation approaches to decomposition in current use are not suitable for binary outcomes. Findings The paper compares three estimation approaches for decomposition of inequality concentration indices: Ordinary Least Squares (OLS), probit, and the Generalized Linear Model (GLM) binomial distribution and identity link. Data are from the Thai Health and Welfare Survey 2003. The OLS estimates do not take into account the binary nature of the outcome and the probit estimates depend on the choice of reference groups, whereas the GLM binomial identity approach has neither of these problems. Conclusions The GLM with binomial distribution and identity link allows the inequality decomposition model to hold, and produces valid estimates of determinants that do not vary according to choice of reference groups. This GLM approach is readily available in standard statistical packages. PMID:20199691

Revision and extension of a multidimensional measure of sexual minority identity: the Lesbian, Gay, and Bisexual Identity Scale.  

PubMed

Two studies were conducted to investigate a revised and extended version of the Lesbian and Gay Identity Scale (Mohr & Fassinger, 2000): the 27-item Lesbian, Gay, and Bisexual Identity Scale (LGBIS). This revision features more inclusive and less stigmatizing language than the previous version and includes 2 new subscales assessing identity affirmation and centrality. In Study 1, an exploratory factor analysis (n = 297) and a confirmatory factor analysis (n = 357) supported an 8-factor solution assessing acceptance concerns, concealment motivation, identity uncertainty, internalized homonegativity, difficulty with the identity development process, identity superiority, identity affirmation, and identity centrality. Predicted associations with measures of identity-related constructs and psychosocial functioning provided preliminary validity evidence for LGBIS scores in a college student population. Study 2 (N = 51) provided evidence of the test-retest and internal consistency reliability of LGBIS scores. These studies suggest that the LGBIS may offer researchers an efficient means of assessing multiple dimensions of sexual orientation minority identity. PMID:21319899

Procedural memory in dissociative identity disorder: when can inter-identity amnesia be truly established?  

PubMed

In a serial reaction time task, procedural memory was examined in Dissociative Identity Disorder (DID). Thirty-one DID patients were tested for inter-identity transfer of procedural learning and their memory performance was compared with 25 normal controls and 25 controls instructed to simulate DID. Results of patients seemed to indicate a pattern of inter-identity amnesia. Simulators, however, were able to mimic a pattern of inter-identity amnesia, rendering the results of patients impossible to interpret as either a pattern of amnesia or a pattern of simulation. It is argued that studies not including DID-simulators or simulation-free memory tasks, should not be taken as evidence for (or against) amnesia in DID. PMID:15950888

Inter-Identity Autobiographical Amnesia in Patients with Dissociative Identity Disorder  

PubMed Central

Background A major symptom of Dissociative Identity Disorder (DID; formerly Multiple Personality Disorder) is dissociative amnesia, the inability to recall important personal information. Only two case studies have directly addressed autobiographical memory in DID. Both provided evidence suggestive of dissociative amnesia. The aim of the current study was to objectively assess transfer of autobiographical information between identities in a larger sample of DID patients. Methods Using a concealed information task, we assessed recognition of autobiographical details in an amnesic identity. Eleven DID patients, 27 normal controls, and 23 controls simulating DID participated. Controls and simulators were matched to patients on age, education level, and type of autobiographical memory tested. Findings Although patients subjectively reported amnesia for the autobiographical details included in the task, the results indicated transfer of information between identities. Conclusion The results call for a revision of the DID definition. The amnesia criterion should be modified to emphasize its subjective nature. PMID:22815769

Host identity impacts rhizosphere fungal communities associated with three alpine plant species.  

PubMed

Fungal diversity and composition are still relatively unknown in many ecosystems; however, host identity and environmental conditions are hypothesized to influence fungal community assembly. To test these hypotheses, we characterized the richness, diversity, and composition of rhizosphere fungi colonizing three alpine plant species, Taraxacum ceratophorum, Taraxacum officinale, and Polemonium viscosum. Roots were collected from open meadow and willow understory habitats at treeline on Pennsylvania Mountain, Colorado, USA. Fungal small subunit ribosomal DNA was sequenced using fungal-specific primers, sample-specific DNA tags, and 454 pyrosequencing. We classified operational taxonomic units (OTUs) as arbuscular mycorrhizal (AMF) or non-arbuscular mycorrhizal (non-AMF) fungi and then tested whether habitat or host identity influenced these fungal communities. Approximately 14% of the sequences represented AMF taxa (44 OTUs) with the majority belonging to Glomus groups A and B. Non-AMF sequences represented 186 OTUs belonging to Ascomycota (58%), Basidiomycota (26%), Zygomycota (14%), and Chytridiomycota (2%) phyla. Total AMF and non-AMF richness were similar between habitats but varied among host species. AMF richness and diversity per root sample also varied among host species and were highest in T. ceratophorum compared with T. officinale and P. viscosum. In contrast, non-AMF richness and diversity per root sample were similar among host species except in the willow understory where diversity was reduced in T. officinale. Fungal community composition was influenced by host identity but not habitat. Specifically, T. officinale hosted a different AMF community than T. ceratophorum and P. viscosum while P. viscosum hosted a different non-AMF community than T. ceratophorum and T. officinale. Our results suggest that host identity has a stronger effect on rhizosphere fungi than habitat. Furthermore, although host identity influenced both AMF and non-AMF, this effect was stronger for the mutualistic AMF community. PMID:22038036

Identity state-dependent attentional bias for facial threat in dissociative identity disorder.  

PubMed

Biased attention for threatening stimuli has been associated with many forms of psychopathology. Attention to threatening faces presented below perceptual thresholds was assessed in patients diagnosed with dissociative identity disorder using a pictorial emotional Stroop task. Patients were tested in two different identity states, in one of which they claimed strong awareness of trauma. Attentional bias for social threat proved state-dependent in the patients and deviated from the patterns observed in controls. PMID:16455142

Pediatric lupus: varied haematological picture and presentation.  

PubMed

Systemic lupus erythematosus (SLE) is a chronic, multisystem, autoimmune disease characterized by periods of increased disease activity caused by inflammation of blood vessels and connective tissue. Pediatric patients with SLE have a more severe clinical course when compared with adults. Patients commonly present with rash, fever, and arthritis, although the presentation may be unpredictable. Hematological findings are more predominant in children than adults. Thirty-nine percent of children with SLE will develop hematological abnormalities, one of the American Rheumatic Association criteria for classifying the disease. In our case series we found varied hematological picture and presentation. We present here four case reports of SLE cases with interesting hematological features. Our first case is a 13 month old female child who was initially diagnosed as Evans syndrome and 2 years later diagnosed as SLE. Second case is a 3 year old male child who had SLE with warm antibody AIHA. Third case is a 6 year old female child who presented with AIHA and was diagnosed with SLE 6 years later. Fourth case is a 6 year old female child diagnosed as SLE with aplastic anemia. Hematological findings should be carefully assessed and treated in order to decrease disease related morbidity.

Memristive biosensors under varying humidity conditions.  

PubMed

We attempt to examine the potential of silicon nanowire memristors in the field of nanobiosensing. The memristive devices are crystalline Silicon (Si) Nanowires (NWs) with Nickel Silicide (NiSi) terminals. The nanowires are fabricated on a Silicon-on-Insulator (SOI) wafer by an Ebeam Lithography Technique (EBL) process that allows high resolution at the nanoscale. A Deep Reactive Ion Etching (DRIE) technique is used to define free-standing nanowires. The close alignment between Silicon (Si) and Nickel-Silicide (NiSi) terminals forms a Schottky-barrier at their junction. The memristive effect of the fabricated devices matches well with the memristor theory. An equivalent circuit reproducing the memristive effect in current-voltage (I-V) characteristics of our silicon nanowires is presented too. The memristive silicon nanowire devices are then functionalized with anti-human VEGF (Vascular Endothelial Growth Factor) antibody and I-V characteristics are examined for the nanowires prior to and after protein functionalization. The uptake of bio-molecules linked to the surface of the memristive NWs is confirmed by the increased voltage gap in the hysteresis curve. The effects of varying humidity conditions on the conductivity of bio-modified memristive silicon nanowires are deeply investigated. PMID:24594511

Extracting Laterally Varying Attenuation from Microseisms  

NASA Astrophysics Data System (ADS)

Noise cross-correlation (NCC) has been successfully used in constructing empirical Green's functions (EGFs) for seismic velocity tomography. However, extracting reliable EGF amplitudes for attenuation estimation remains a challenge despite the fact that there are studies that derive spatially averaged attenuation from noise. In this work we use microseisms recorded by the USArray stations to explore the techniques that may accomplish the task to accurately measure EGF amplitudes and thus provide reliable input to the tomographic mapping of the laterally varying attenuation. Traditional NCC processing often trades amplitude information for phases with a better signal-to-noise ratio (SNR). An equally efficient method, temporal flattening, which removes the dominance of high-level noise in particular time intervals, and yet keeps the relative amplitudes among stations, is to normalize the narrow-band signals at each station by an average of the noise energy level at all stations. In addition to the effect of traditional NCC processing, EGF amplitude can also be biased by the uneven distribution of noise-field intensity in space, time and direction. To mitigate the effect of anisotropic noise field, we calculate EGFs using beam cross-correlation (BCC). Namely we construct beams according to the strike of a station pair and the surface-wave velocity, so that the beam signal contains mainly the energy flux along the strike. We validate our methods by comparing the surface-wave amplitudes from an earthquake with relative EGF amplitudes from a "source" station near the earthquake.

Serotonin release varies with brain tryptophan levels  

NASA Technical Reports Server (NTRS)

This study examines directly the effects on serotonin release of varying brain tryptophan levels within the physiologic range. It also addresses possible interactions between tryptophan availability and the frequency of membrane depolarization in controlling serotonin release. We demonstrate that reducing tryptophan levels in rat hypothalamic slices (by superfusing them with medium supplemented with 100 microM leucine) decreases tissue serotonin levels as well as both the spontaneous and the electrically-evoked serotonin release. Conversely, elevating tissue tryptophan levels (by superfusing slices with medium supplemented with 2 microM tryptophan) increases both the tissue serotonin levels and the serotonin release. Serotonin release was found to be affected independently by the tryptophan availability and the frequency of electrical field-stimulation (1-5 Hz), since increasing both variables produced nearly additive increases in release. These observations demonstrate for the first time that both precursor-dependent elevations and reductions in brain serotonin levels produce proportionate changes in serotonin release, and that the magnitude of the tryptophan effect is unrelated to neuronal firing frequency. The data support the hypothesis that serotonin release is proportionate to intracellular serotonin levels.

Honeybee odometry: performance in varying natural terrain.  

PubMed

Recent studies have shown that honeybees flying through short, narrow tunnels with visually textured walls perform waggle dances that indicate a much greater flight distance than that actually flown. These studies suggest that the bee's "odometer" is driven by the optic flow (image motion) that is experienced during flight. One might therefore expect that, when bees fly to a food source through a varying outdoor landscape, their waggle dances would depend upon the nature of the terrain experienced en route. We trained honeybees to visit feeders positioned along two routes, each 580 m long. One route was exclusively over land. The other was initially over land, then over water and, finally, again over land. Flight over water resulted in a significantly flatter slope of the waggle-duration versus distance regression, compared to flight over land. The mean visual contrast of the scenes was significantly greater over land than over water. The results reveal that, in outdoor flight, the honeybee's odometer does not run at a constant rate; rather, the rate depends upon the properties of the terrain. The bee's perception of distance flown is therefore not absolute, but scene-dependent. These findings raise important and interesting questions about how these animals navigate reliably.

Tracking Moving Identities: After Attending the Right Location, the Identity Does Not Come for Free  

PubMed Central

Although tracking identical moving objects has been studied since the 1980's, only recently the study into tracking moving objects with distinct identities has started (referred to as Multiple Identity Tracking, MIT). So far, only behavioral studies into MIT have been undertaken. These studies have left a fundamental question regarding MIT unanswered, is MIT a one-stage or a two-stage process? According to the one-stage model, after a location has been attended, the identity is released without effort. However, according to the two-stage model, there are two effortful stages in MIT, attending to a location, and attending to the identity of the object at that location. In the current study we investigated this question by measuring brain activity in response to tracking familiar and unfamiliar targets. Familiarity is known to automate effortful processes, so if attention to identify the object is needed, this should become easier. However, if no such attention is needed, familiarity can only affect other processes (such as memory for the target set). Our results revealed that on unfamiliar trials neural activity was higher in both attentional networks, and visual identification networks. These results suggest that familiarity in MIT automates attentional identification processes, thus suggesting that attentional identification is needed in MIT. This then would imply that MIT is essentially a two-stage process, since after attending the location, the identity does not seem to come for free. PMID:22927940

Dynamics of identity in the academic field and implications to science students' identity formation  

NASA Astrophysics Data System (ADS)

Aydeniz and Hodge investigated how college professors negotiate their responsibilities as teachers and as researchers and the rationales behind their pedagogical approaches. Their findings illustrate how difficult it can be to keep the balance between these two responsibilities in a university that does not support professor's enactment of teaching goals. Thinking identity as a dynamics in self and institutional boundary, Albrecht and Fortney in their forum contribution, expand the analysis of Professor G's professional identity and conclude that in his case, institutional boundary is impermeable as it values research scientist more than teacher identity. In this forum contribution I emphasize the role of institutional culture in the identitarian process, interpreting the identity and identity formation of a science college teacher within the dynamics of the academic field. I expand the discussion to the other side of the problem, bringing excerpts of an interview with a Physics student from a Brazilian university as an illustration of how the academic habitus can impact the formation of a student's identity.

Determinant factors of gender identity: a commentary.  

PubMed

Paediatric specialists involved in the care of children with disorders of sex development may be expected to provide straightforward answers to questions concerning the "true sex" of a child, reflecting common perceptions of sex/gender as an immutable binary biological reality. This article highlights how much more broad and complex the topic of gender identity and its development is. Many theories have been put forward to advance knowledge of gender identity. Against the breadth and depth of this vast topic, the current overview is inevitably incomplete. It begins by arguing for a more consistent use of 'sex' and 'gender'. It considers in turn three influential theoretical frameworks that lend themselves to empirical research. These are: 1) the role of the brain; 2) the role of socialisation; and 3) multi-dimensional gender development. The article ends by suggesting potentially fruitful questions and areas for future research. PMID:23158728

Cooperative spontaneous emission of three identical atoms  

E-print Network

We study the influence of the distribution of atoms on the cooperative spontaneous emission by a simple model of three identical atoms. The effects of counter rotating terms are included by a unitary transformation method. By discussing two special cases that the three atoms are arranged as an equilateral triangle and in a straight line, we find that the superradiance of the coherent system largely dependent on the homogeneity of the atoms' distribution. If the atoms distribute symmetrically, the superradiant emission will be enhanced. Next, we calculate the emission spectra of three identical atoms under the single-photon state. We find that the distribution of atoms also has a great impact on the lamb shift and the spectrum. If three atoms are placed into an equilateral triangle and the same dipole moment is perpendicular to the plane of the three atoms, the spectrum will degenerate into two peaks from the three peaks for general case.

Spatial separation and entanglement of identical particles  

E-print Network

We reconsider the effect of indistinguishability on the reduced density operator of the internal degrees of freedom (tracing out the spatial degrees of freedom) for a quantum system composed of identical particles located in different spatial regions. We explicitly show that if the spin measurements are performed in disjoint spatial regions then there are no constraints on the structure of the reduced state of the system. This implies that the statistics of identical particles has no role from the point of view of separability and entanglement when the measurements are spatially separated. We extend the treatment to the case of n particles and show the connection with some recent criteria for separability based on subalgebras of observables.

Remote secure proof of identity using biometrics  

SciTech Connect

Biometric measurements derived from finger- or voiceprints, hand geometry, retinal vessel pattern and iris texture characteristics etc. can be identifiers of individuals. In each case, the measurements can be coded into a statistically unique bit-string for each individual. While in electronic commerce and other electronic transactions the proof of identity of an individual is provided by the use of either public key cryptography or biometric data, more secure applications can be achieved by employing both. However the former requires the use of exact bit patterns. An error correction procedure allows us to successfully combine the use of both to provide a general procedure for remote secure proof of identity using a generic biometric device. One such procedure has been demonstrated using a device based on hand geometry.

Dissociative identity disorder presenting as dermatitis artefacta.  

PubMed

Dermatitis artefacta is a rare psychiatric condition characterized by rubbing of skin blisters and denial of self-infliction. Dissociation may be comorbid with self-injurious behavior. A background of emotional disturbances during formative years and in later life often results in feelings of isolation and insecurity, which can lead to dissociation as a primary defense mechanism used to overcome traumatic events. In this case report, we describe a female patient with dermatitis artefacta associated with dissociative identity disorder. The patient was a 14-year-old girl. Multiple large, deep ulcerations with unnatural shapes were seen on her left forearm. The ulcerations were thought to be self-inflicted. Psychiatric examination revealed that she had a different identity, and inflicted the lesions when this was assumed. This case leads us to suggest that patients with dermatitis artefacta might have comorbid dissociative experiences, which cannot be identified easily. PMID:16796649

Meristem identity and phyllotaxis in inflorescence development  

PubMed Central

Inflorescence morphology is incredibly diverse. This diversity of form has been a fruitful source of inquiry for plant morphologists for more than a century. Work in the grasses (Poaceae), the tomato family (Solanaceae), and Arabidopsis thaliana (Brassicaceae) has led to a richer understanding of the molecular genetics underlying this diversity. The character of individual meristems, a combination of the number (determinacy) and nature (identity) of the products a meristem produces, is key in the development of plant form. A framework that describes inflorescence development in terms of shifting meristem identities has emerged and garnered empirical support in a number of model systems. We discuss this framework and highlight one important aspect of meristem identity that is often considered in isolation, phyllotaxis. Phyllotaxis refers to the arrangement of lateral organs around a central axis. The development and evolution of phyllotaxis in the inflorescence remains underexplored, but recent work analyzing early inflorescence development in the grasses identified an evolutionary shift in primary branch phyllotaxis in the Pooideae. We discuss the evidence for an intimate connection between meristem identity and phyllotaxis in both the inflorescence and vegetative shoot, and touch on what is known about the establishment of phyllotactic patterns in the meristem. Localized auxin maxima are instrumental in determining the position of lateral primordia. Upstream factors that regulate the position of these maxima remain unclear, and how phyllotactic patterns change over the course of a plant's lifetime and evolutionary time, is largely unknown. A more complete understanding of the molecular underpinnings of phyllotaxis and architectural diversity in inflorescences will require capitalizing on the extensive resources available in existing genetic systems, and developing new model systems that more fully represent the diversity of plant morphology.

Finding New Math Identities by Computer  

NASA Technical Reports Server (NTRS)

Recently a number of interesting new mathematical identities have been discovered by means of numerical searches on high performance computers, using some newly discovered algorithms. These include the following: pi = ((sup oo)(sub k=0))(Sigma) (1 / 16) (sup k) ((4 / 8k+1) - (2 / 8k+4) - (1 / 8k+5) - (1 / 8k+6)) and ((17 pi(exp 4)) / 360) = ((sup oo)(sub k=1))(Sigma) (1 + (1/2) + (1/3) + ... + (1/k))(exp 2) k(exp -2), zeta(3, 1, 3, 1, ..., 3, 1) = (2 pi(exp 4m) / (4m+2)! where m = number of (3,1) pairs. and where zeta(n1,n2,...,nr) = (sub k1 (is greater than) k2 (is greater than) ... (is greater than) kr)(Sigma) (1 / (k1 (sup n1) k2 (sup n2) ... kr (sup nr). The first identity is remarkable in that it permits one to compute the n-th binary or hexadecimal digit of pu directly, without computing any of the previous digits, and without using multiple precision arithmetic. Recently the ten billionth hexadecimal digit of pi was computed using this formula. The third identity has connections to quantum field theory. (The first and second of these been formally established; the third is affirmed by numerical evidence only.) The background and results of this work will be described, including an overview of the algorithms and computer techniques used in these studies.

Identity concept learning in matching-to-sample tasks by tufted capuchin monkeys (Cebus apella).  

PubMed

The abstract concept of equivalence is considered one of the bases of higher-order cognition, and it has been the subject of considerable research in comparative cognition. This study examined the conditions under which tufted capuchin monkeys (Cebus apella) are able to acquire an identity concept. Six capuchin monkeys were trained to solve a visual matching-to-sample (MTS) task on the basis of perceptual identity. The acquisition of the identity rule was inferred from the subject's ability to solve transfer tests with novel stimuli. We evaluated the ability of the capuchin monkeys to match the shape of novel stimuli after training with both several small stimulus sets (Experiment 1) and a large stimulus set (Experiment 2). Moreover, we examined the ability of capuchins to transfer the concept to novel visual dimensions, such as colour and size and to transfer to novel spatial arrangements of the stimuli (Experiment 2). We demonstrated that the ability of capuchins to match novel stimuli was improved by increasing the number of stimuli used during training (Experiments 1 and 2) and that after a widely applicable identity concept based on the stimulus shape was acquired, the capuchins were able to match stimuli according to an identity rule based on both the colour and size of the stimuli and when the spatial arrangement of the stimuli was varied (Experiment 2). This study is the first to demonstrate that the size of the training set affects the acquisition of an abstract identity concept in an MTS task in non-human primates. PMID:20574839

Cosmology with Time-Varying G  

NASA Astrophysics Data System (ADS)

It is shown that a Universe with a time-varying gravitational “constant” G necessarily implies creation if the rest mass of matter particles m p is constant. In this case, from Einstein's field equations, the conditions for energy-momentum propagation are ? ·( GT ? v ) from which matter and photon propagation equations are derived. Free matter particle propagation is not affected by creation that is given by GN pmp=const, where N p is the number of matter particles within a proper volume. This relation introduces explicitly the rest mass of the Universe into the field equations. Free photon propagation is affected by creation that is given by GT ? v R=const, where N ? is the number of photons within a proper volume, which is the cosmic red shift law. Conservation of the cosmic background photon distribution determines photon creation as G 3 N {?/4}. The results are applied to the case G ? t -1 equivalent to N p ÷ t. It is found that at an age t=1, 0-40 t o, of the order light takes to travel a proton size, Planck's units become of the order of the proton's mass m p, size r p, and time r p/c. Hence, matter particles at this age are quantum black holes. Evaporation of these quantum black holes at this age gives a background blackbody radiation that, red shifted to present time t 0, gives the present cosmic microwave background. A cosmological model of the Friedmann type is constructed. The red shift versus distance relation is derived taking into account creation. Using a Hubble's constant H obs=50 km sec-1 Mpc-1 and a deceleration parameter q obs=1.0 the model is of the type k=1 and gives a present age t 0=6.81×109 yr, consistent with Uranium model ages. Thus, the three results for the age of the Universe, i.e., radioactive decay, Hubble's constant, and stellar evolution are brought together in this creation model. The matter-dominated era occurs for t>7.6×10-3 t 0, while the radiation-dominated era occurs for 7.6×10-3 t o> t>10-40 t o. The origin of the Universe is placed at this last limit, which is Planck's time at the corresponding G, consisting of quantum black holes at a temperature Ti?=3×1011K.

Developing a workable teacher identity: Building and negotiating identity within a professional network  

NASA Astrophysics Data System (ADS)

The challenge of attracting and retaining the next generation of teachers who are skilled and committed to meeting the growing demands of the profession is of increasing concern to researchers and policy makers, particularly since 45--50% of beginning teachers leave the profession within five years (Ingersoll & Smith, 2003). Reasons for such attrition include compensation, status and working conditions; however, there is growing evidence that a critical factor in new teacher retention hinges on teachers' ability to accomplish the difficult task of forming a workable professional identity in the midst of competing discourses about teaching (Alsup, 2006; Britzman, 2003). There is little research on professional identity development among those beginning teachers at highest risk for attrition (secondary math and science teachers, and those with strong academic backgrounds). This study explores the professional identity development of early-career math and science teachers who are part of the Knowles Science Teaching Foundation's (KSTF) teaching fellowship program, an external support network that aims to address many of the issues leading to high attrition among this particular population of teachers. Using narrative research methods, I examine three case studies of beginning teachers, exploring how they construct professional identity in relation to various discourse communities and negotiate tensions across multiple discourses. The cases identify both dominant discourses and counter-discourses that the teachers draw upon for important identity development resources. They also demonstrate that the way a teacher manages tensions across competing discourses is important to how well one can negotiate a workable professional identity. In particular, they emphasize the importance of engaging in borderland discourses (Gee, 1996) as a way of taking agency in one's own identity development as well as in transforming one's discourse communities. These cases shed light on how these beginning teachers work to negotiate a workable professional identity that may sustain them in a teaching career. In addition, they help us understand how a support network like KSTF can serve as a resource for helping new teachers construct professional identities, therefore addressing some of the issues that may lead to attrition among this population of new teachers.

Neprilysin Is Identical to Skin Fibroblast Elastase  

PubMed Central

Although human skin fibroblast (HSF) elastase has been characterized as a membrane-bound metalloproteinase, little is known about its structure, amino acid sequence, and encoding gene. As there are similarities in the molecular weights and inhibitory profiles of HSF elastase and neprilysin (neutral endopeptidase 24.11 (NEP)), in this study we tested the hypothesis that they are identical using immunoprecipitation and transfection methods. An immunoprecipitation study demonstrated that HSF elastase activity co-immunoprecipitated with anti-NEP in lysates of cultured HSF. Transfection of an NEP cDNA expression vector into COS-1 cells elicited the expression of HSF elastase and NEP activities in the transfected cells. These findings strongly suggest that HSF elastase is identical to NEP, which functions mainly in neuron-associated cells to degrade neuropeptides. Analysis of the expression pattern of NEP revealed that its expression was remarkably up-regulated at the gene, protein, and enzymatic activity levels during the replicative senescence of cultured HSF. Further, the activity of NEP was markedly enhanced in a pattern similar to elastase activity during the intrinsic aging of mouse skin, in UVA-exposed HSF as well as in HSF treated with conditioned medium from UVB-exposed human keratinocytes. Analysis of the cytokine profile for the stimulation of NEP and HSF elastase activities in HSF demonstrated that among the 11 cytokines tested, IL-1?, IL-1?, IL-6, IL-8, and GM-CSF had the potential to significantly stimulate both activities similarly, again supporting the identity of HSF elastase and NEP.

The Homo Energeticus: maturity, inheritance, identity  

NASA Astrophysics Data System (ADS)

In this letter, modern society’s intimate bond to the convenience and reliability of delivered energy services results in a form of identification I call the Homo Energeticus. The Homo Energeticus relies upon a mature system of services for achieving an equivalency of status and prestige that is historically similar to the morality of a noble class. I describe the uniqueness of this identity by its imperative for acquiring experience through an invisibility of energy expenditures. In this way, the Homo Energeticus cultivates a highly individualized life whose ambience of perfection, while created personally, is only successful insofar as it conceals energy expenditures in labor and supply.

Entanglement Entropy Flow and the Ward Identity  

NASA Astrophysics Data System (ADS)

We derive differential equations for the flow of entanglement entropy as a function of the metric and the couplings of the theory. The variation of the universal part of entanglement entropy under a local Weyl transformation is related to the variation under a local change in the couplings. We show that this relation is, in fact, equivalent to the trace Ward identity. As a concrete application of our formalism, we express the entanglement entropy for massive free fields as a two-point function of the energy-momentum tensor.

Representing Identity and Equivalence for Scientific Data  

NASA Astrophysics Data System (ADS)

Matters of equivalence and identity are central to the stewardship of scientific data. In order to properly prepare for and manage the curation, preservation and sharing of digitally-encoded data, data stewards must be able to characterize and assess the relationships holding between data-carrying digital resources. However, identity-related questions about resources and their information content may not be straightforward to answer: for example, what exactly does it mean to say that two files contain the same data, but in different formats? Information content is frequently distinguished from particular representations, but there is no adequately developed shared understanding of what this really means and how the relationship between content and its representations hold. The Data Concepts group at the Center for Informatics Research in Science and Scholarship (CIRSS), University of Illinois at Urbana Champaign, is developing a logic-based framework of fundamental concepts related to scientific data to support curation and integration. One project goal is to develop precise accounts of information resources carrying the same data. We present two complementary conceptual models for information representation: the Basic Representation Model (BRM) and the Systematic Assertion Model (SAM). We show how these models provide an analytical account of digitally-encoded scientific data and a precise understanding of identity and equivalence. The Basic Representation Model identifies the core entities and relationships involved in representing information carried by digital objects. In BRM, digital objects are symbol structures that express propositional content, and stand in layered encoding relationships. For example, an RDF description may be serialized as either XML or N3, and those expressions in turn may be encoded as either UTF-8 or UTF-16 sequences. Defining this encoding stack reveals distinctions necessary for a precise account of identity and equivalence relationships. The Systematic Assertion Model focuses on key provenance events through which propositional content and symbol structures acquire the status of data content and data, respectively. Attention is on events such as a selection of symbols to express propositional content, or an appeal to observational evidence to advance a claim. SAM explicitly identifies data as the primary form of expression the one directly expressing content for a systematic assertion, an assertion where claims are warranted by an observation or a computation event. Under these models, equivalence relationships may hold between different data expressing the same content, or between different encodings of the same data. Equivalence relationships also hold among different data supporting the same claim and when contrasting claims are based on the same observations. SAM and BRM support a fine-grained characterization of scientific equivalence relationships that can be documented through ordinary data stewardship practices.

Identity, prudential concern, and extended lives.  

PubMed

Recent advances in human genetics suggest that it may become possible to genetically manipulate telomerase and embryonic stem cells to alter the mechanisms of aging and extend the human life span. But a life span significantly longer than the present norm would be undesirable because it would severely weaken the connections between past- and future-oriented mental states and turn the psychological grounds for personal identity and prudential concern for our future selves. In addition, the collective effects of longer lives might lower the quality of life for all people. These two problems provide reasons against genetic manipulation of cells to alter the length of the human life span. PMID:12211249

Ethnic identity, region, and attitudes toward male circumcision in a high HIV–prevalence country  

PubMed Central

We study how considerations of male circumcision as both a favourable practice and as protective against HIV are linked with ethnicity in sub-Saharan Africa, where many ethnic groups do not traditionally circumcise. We focus on Malawi, a country with a high HIV prevalence but low male circumcision prevalence. Survey data from a population-based random sample in rural Malawi (N=3400) was analysed for ethnoregional patterns in attitudes toward male circumcision. We used logit regression models to measure how reported circumcision status, region of residence, and ethnic identity relate to attitudes toward circumcision. Overall, Malawians reported more negative than positive opinions about male circumcision, but attitudes toward circumcision varied by ethnicity and region. The implications for agencies and governments aggressively scaling up the provision of male circumcision are clear: acceptance of circumcision as a tool for HIV prevention could be low in societies divided by ethnoregional identities that also shape the practice of circumcision.

Speed of call delivery is related to context and caller identity in Campbell's monkey males  

NASA Astrophysics Data System (ADS)

Call rate can be a salient feature in animal communication. Depending on the species, different psychological variables appear to influence call rates but the exact nature of these relationships remains poorly explored. Here, we demonstrate for free-ranging Campbell’s monkeys that the call rates of four different alarm series (termed H, K, K+, and B series) vary systematically as a function of context, associated behaviour, and identity of the caller. K+ series were given more rapidly to predation than non-predation events, K+ and K series more rapidly to visual than auditory predator detection, and H series more rapidly while counterattacking an eagle than staying put. Finally, there were individual differences in B series, suggesting that call rate potentially provides listeners with cues about the caller’s anti-predator behaviour, event type experienced, and his identity.

The effect of varying ''input realism'' or varying completeness of the input data for linear microinstability calculations, in particular on the critical value of the ion temperature gradient for the ion temperature gradient mode, is investigated using gyrokinetic and gyrofluid approaches. The calculations show that varying input realism can have a substantial quantitative effect on the results.

Comparing Identity Management Frameworks in a Business Context  

NASA Astrophysics Data System (ADS)

Several frameworks for identity management exist, each of them with its own distinguishing features. These frameworks are complex however, and their features not easily understood. This makes it hard for businesses to understand the intricacies, and difficult to select and deploy one. This paper develops business selection criteria and applies them to four popular identity management frameworks. The resulting score card (1) helps businesses to select and deploy an identity management system, and (2) provides valuable feedback to developers of identity management systems on the criteria that they should take into account when designing and implementing an identity management system that is useful for specific businesses.

Identity and psychological ownership in chronic illness and disease state  

PubMed Central

Psychological ownership is rarely considered in health discourse related to chronic illness or disease state. Construction of identity is an important consideration within this framework. This autoethnographic study explores psychological ownership and identity related to prostate cancer and chronic illness. Conclusions about the nature of psychological ownership and identity were gathered from the relevant literature and personal experience. Themes include the patient–healthcare professional relationship and that psychological ownership is personal and grounded in an individual's sense of identity, control and perceived capacity to control illness or disease. Personal reflection through autoethnography guides discussion of psychological ownership and identity. PMID:20738388

A cosmological Slavnov-Taylor identity  

NASA Astrophysics Data System (ADS)

We develop a method for treating the consistency relations of inflation that includes the full time-evolution of the state. This approach relies only on the symmetries of the inflationary setting, in particular a residual conformal symmetry in the spatial part of the metric, along with general properties which hold for any quantum field theory. As a result, the consistency relations that emerge, which are essentially the Slavnov-Taylor identities associated with this residual conformal symmetry, apply very generally: they are true of the full Green's functions, hold largely independently of the particular inflationary model, and can be used for arbitrary states. We illustrate these techniques by showing the form assumed by the standard consistency relation between the two and three-point functions for the primordial scalar fluctuations when they are in a Bunch-Davies state. But because we have included the full evolution of the state, this approach works for a general initial state as well and does not need to have assumed that inflation began in the Bunch-Davies state. We explain how the Slavnov-Taylor identity is modified for these more general states.

Solution to the Ward identities for superamplitudes  

NASA Astrophysics Data System (ADS)

Supersymmetry and R-symmetry Ward identities relate on-shell amplitudes in a supersymmetric field theory. We solve these Ward identities for N K MHV amplitudes of the maximally supersymmetric mathcal{N} = 4 and mathcal{N} = 8 theories. The resulting superamplitude is written in a new, manifestly supersymmetric and R-invariant form: it is expressed as a sum of very simple SUSY and {text{SU}}{left( mathcal{N} right)_R} -invariant Grassmann polynomials, each multiplied by a “basis amplitude”. For N K MHV n-point superamplitudes the number of basis amplitudes is equal to the dimension of the irreducible representation of SU( n - 4) corresponding to the rectangular Young diagram with mathcal{N} columns and K rows. The linearly independent amplitudes in this algebraic basis may still be functionally related by permutation of momenta. We show how cyclic and reflection symmetries can be used to obtain a smaller functional basis of color-ordered single-trace amplitudes in mathcal{N} = 4 gauge theory. We also analyze the more significant reduction that occurs in mathcal{N} = 8 supergravity because gravity amplitudes are not ordered. All results are valid at both tree and loop level.

Balanced Identity in the Minimal Groups Paradigm  

PubMed Central

Balanced Identity Theory [1] formalizes a set of relationships between group attitude, group identification, and self-esteem. While these relationships have been demonstrated for familiar and highly salient social categories, questions remain regarding the generality of the balance phenomenon and its causal versus descriptive status. Supporting the generality and rapidity of cognitive balance, four studies demonstrate that the central predictions of balance are supported even for previously unfamiliar “minimal” social groups to which participants have just been randomly assigned. Further, supporting a causal as opposed to merely descriptive interpretation, manipulating any one component of the balance model (group attitude, group identification, or self-esteem) affects at least one of the related components. Interestingly, the broader pattern of cognitive balance was preserved across such manipulations only when the manipulation strengthens as opposes to weakens the manipulated construct. Taken together, these findings indicate that Balanced Identity Theory has promise as a general theory of intergroup attitudes, and that it may be able to shed light on prior inconsistencies concerning the relationship between self-esteem and intergroup bias.

Experimental insights on the effects of varying discharge on fluvial landscape evolution  

NASA Astrophysics Data System (ADS)

River floods are known to have large impacts on fluvial morphology as the capacity to carry water and rework sediment during these events is large. However, recent experimental findings are conflicting: some suggest that varying discharge contributes to a more single-thread pattern whereas others suggest that discharge variations cause multiple threads to be active, and yet others show no significant effect on the morphology. Our objective is to study the effect of varying discharge on experimental river patterns with otherwise similar conditions, and to quantitatively compare the resulting morphology and deposits. Our experiments were conducted in a flume of 10x6 meter, which was split up into two separate fluvial plains (each 10x3 m). Fluvial landscape evolution was recorded by high-resolution line-laser scanning and digital Single Lens Reflex (SLR) camera used for channel-floodplain segmentation and particle size estimation. The bed sediment consisted of a poorly sorted sediment mixture ranging from fine sand to fine gravel. First, a braided and meandering river pattern evolved for identical and constant boundary conditions, except that slightly cohesive silt-sized silica flour was added to the feed sediment of the meandering channel. A second set of experiments had an identical cycled discharge regime with a long-duration low flow and a short-duration high flow.The varying discharge largely affected the fluvial landscape by biasing the morphology towards the high flow conditions. This was reflected by an increase of the bar wave length with nearly a factor 2. Also, the depth of maximum erosion increased, which affects the preservation potential. The meandering and braided patterns responded differently to the floods. The noncohesive sediment combination with varying discharge results in a higher degree of braiding when compared to constant discharge. This was observed as a higher number of re-activating channels during high flow. In contrast, the silica flour acted as floodplain builder, which was more efficiently distributed during floods. As a result, the system with slightly cohesive sediment remained mostly confined to one migrating meandering channel that developed scroll bars, channel fills, splays and levees. We conclude that the response to varying discharge depends on the availability and cohesion of fine floodplain-forming sediment in combination with the potential of high flows to re-activate residual channels.

Multiple identities in social perception and interaction: challenges and opportunities.  

PubMed

Categorization plays a fundamental role in organizing daily interactions with the social world. However, there is increasing recognition that social categorization is often complex, both because category membership can be ambiguous (e.g., multiracial or transgender identities) and because different categorical identities (e.g., race and gender) may interact to determine the meaning of category membership. These complex identities simultaneously impact social perceivers' impressions and social targets' own experiences of identity, thereby shaping perceptions, experiences, and interactions in fundamental ways. This review examines recent research on the perception and experience of the complex, multifaceted identities that both complicate and enrich our lives. Although research has historically tended to focus more on difficulties and challenges associated with multiple identities, increasing attention is being paid to opportunities that emerge from the possession of identities that include multiple distinct or overlapping groups. We consider how these opportunities might benefit both perceivers and targets. PMID:25061671
