The accuracy of intensity ratings of emotions from facial expressions

The results of a study on the accuracy of intensity ratings of emotion from facial expressions are reported. The so far research into the field has shown that spontaneous facial expressions of basic emotions are a reliable source of information about the category of emotion. The question is raised of whether this can be true for the intensity of emotion as well and whether the accuracy of intensity ratings is dependent on the observer’s sex and vocational orientation. A total of 228 observers of both sexes and of various vocational orientations rated the emotional intensity of presented facial expressions on a scale-range from 0 to 8. The results have supported the hypothesis that spontaneous facial expressions of basic emotions do provide sufficient information about emotional intensity. The hypothesis on the interdependence between the accuracy of intensity ratings of emotion and the observer’s sex and vocational orientation has not been confirmed. However, the accuracy of intensity rating has been proved to vary with the category of the emotion presented.
Experimental Evaluation of Energy Efficiency for a Soft Wearable Robotic Suit

This paper presents a new soft wearable robotic suit for energy-efficient walking in daily activities for elderly persons. The presented robotic suit provides a small yet effective assistive force for hip flexion through winding belts that include elastic elements. In addition, it does not restrict the range of movement in the lower limbs. Moreover, its structure is simple and lightweight, and thus wearers can easily take the device on and off by themselves. Experimental results on nine elderly subjects (age = 74.2±3.7 years) show that the robotic suit worn and powered on (PON) significantly reduced energy expenditure by an average of 5.9% compared with the condition of worn but powered off (POFF). Furthermore, compared with the POFF condition, there was a significant improvement in gait characteristics in the PON condition for all subjects.
Formation and evolution of dwarf elliptical galaxies - I. Structural and kinematical properties

This paper is the first in a series in which we present the resul ts of an ESO Large Program on the kinematics and internal dynamics of dwarf elliptical galaxies (dEs). We obtained deep major and minor axis spectra of 15 dEs and broad-band imaging of 22 dEs. Here, we investigate the relations between the parameters that quantify the structure (B-band luminosity LB, half-light radius Re, and mean surface brightness within the half-light radius Ie = LB/2πR 2) and internal dynamics (ve- locity dispersion σ) of dEs. We confront predictions of the currently popular theories for dE formation and evolution with the observed position of dEs in log LB vs. logσ, log LB vs. log Re, log LB vs. log Ie, and log Re vs. log Ie diagrams and in the (logσ, log Re, log Ie) parameter space in which bright and intermediate-luminosity elliptical galaxies and bulges of spirals define a Fundamental Plane (FP). In order to achieve statistical si gnificance and to cover a parameter interval that is large eno ugh for reliable inferences to be made, we merge the data set presented in this paper with two other recently published, equally large data sets. We show that the dE sequences in the various univariate diagrams are disjunct from those traced by bright and intermediate- luminosity elliptical galaxies and bulges of spirals. It ap pears that semi-analytical models (SAMs) that incorporate quiescent star formation with an essentially z-independent star-formation effi ciency, combined with post-merger starbursts and the dynamical response after supernova-driven gas-loss, are able to repr oduce the position of the dEs in the various univariate diagrams. SAMs with star-formation effi ciencies that rise as a function of redshift are excluded sin ce they leave the observed sequences traced by dEs virtually unpopulated. dEs tend to lie above the FP and the FP residual declines as a function of luminosity. Again, models that take into account the response after supernova-driven mass-loss correctly predict the position of d Es in the (logσ, log Re, log Ie) parameter space as well as the trend of the FP residual as a function of luminosity. While these findings are clearly a success for the hierarchic al-merging picture of galaxy formation, they do not necessarily invalidate the alternative "harassment" scenario, which posits that dEs stem from perturbed and stripped late-type disk galaxies that entered clusters and groups of galaxies about 5 Gyr ago.
Mutual Relations Between Mothers' Depressive Symptoms and Hostile-Controlling Behavior and Young Children's Externalizing and Internalizing Behavior Problems

Objective. This study considered the role of mothers' depressive symptoms and hostile-controlling behavior in young children's externalizing and internalizing behavior problems. Pathways of influence between mothers' depressive symptoms and hostile-controlling behavior and children's externalizing and internalizing behavior problems also were examined. Design. Data were collected at child ages 4 and 6 years from a nonclinical, community sample of 51 mothers and their children. At both assessments, mothers' behavior was observed during a structured mother - child play activity, and mothers completed questionnaires to assess their depressive symptoms and children's externalizing and internalizing symptoms. Results. Hierarchical regression analyses revealed different patterns of findings across the 2 assessments as well as different patterns of findings for children's externalizing versus internalizing behaviors. At age 4, mothers' depressive symptoms and hostile-controlling behavior predicted children's externalizing behaviors; at age 6, only mothers' hostile-controlling behavior predicted children's externalizing behaviors. Regarding children's internalizing behaviors, mothers' depressive symptoms were significant predictors at child age 4; however, by age 6, mothers' depressive symptoms were no longer significant predictors. When longitudinal modeling was applied to the data, some support for both maternal and child effects was found. Conclusions. Findings highlight the importance of considering mothers' depressive symptoms and hostile-controlling behavior in predicting children's externalizing and internalizing behavior problems and suggest different etiological pathways for externalizing versus internalizing expressions of dysfunction.
Forecast 2000: Widening Knowledge Gaps

This report updates a 1983 analysis of fifty-eight knowledge gap studies, adding thirty-nine studies and pointing out innovative ways to improve research in the area. The persistence of knowledge inequalities across topics and research settings has serious consequences. Gaps in public affairs and health knowledge have an especially severe impact on those groups most negatively affected by socioeconomic changes, who also tend to be information poor. Rapid growth of socioeconomic divisions between “haves” and “have-nots” in the last two decades suggests that knowledge gaps deserve increased research attention because they are related and potentially affected phenomena.
NCAA Division I Coaches’ Perceptions and Preferred Use of Sport Psychology Services: A Qualitative Perspective

Although there appears to be greater acceptance and use of sport psychology (SP), fully integrating SP consultants and services into college athletic programs has yet to occur in most institutions. Decisions to initiate, continue, or terminate SP services are often made by coaches. Therefore, college coaches with access to services were interviewed to explore their beliefs and expectations about SP service use and how an SP consultant could work effectively with them and their athletes. Using consensual qualitative research methods, three domains in coaches’ perceptions of SP consultants were revealed: who they are, what they do, and how they do it. Findings illustrate the importance of being “on the same page” with coaches, developing self-reliant athletes, and making an impact while remaining in a supporting role.
Language attitudes toward varieties of English: An American‐Japanese context

Abstract To our knowledge, no data exist on attitudes toward speakers with Japanese accented varieties of American English, an area of profound significance given increasing American‐Japanese contacts across a wide range of applied contexts. This “matched‐guise” study provides such by eliciting Americans’ reactions to a Japanese male talking on two different topics (aggressive versus neutral) using four language varieties (viz., standard, moderate‐accented, heavy‐accented, and disfluent). Speaker evaluations on status, attractiveness, and dynamism traits confirmed certain predictions based on the literature, but some surprising, yet interpretable, patterns emerged in this new domain of American‐Japanese inquiry. Specifically, it was found that Japanese‐accented speakers were evaluated in manner unlike all other non‐standard accented speakers of American English, except those of British and Malaysian background. It is suggested that perceptions of social group competitiveness may be responsible for this pa.
Doing, Redoing, and Undoing Gender

For a study of police women’s identities, qualitative data were generated from in-depth interviews with 21 women working in two metropolitan police departments and varying in race, ethnicity, rank, and tenure. Most women identified female-male differences but noted exceptions. Many felt characteristics concentrated among women enhanced job performance, and men’s characteristics damaged performance. Several insisted that sex-category differences in key attributes accounting for good police work were nonexistent or minimal. Women do not simply reproduce old female-male stereotypes and the hierarchies that devalue female-associated traits. They fashion complex, positive occupational identities that are not necessarily tied to their sex category.
Self-reported emotional intelligence: Construct similarity and functional dissimilarity of higher-order processing in Iran and the United States

This study employed the Trait Meta-Mood Scale (TMMS) to assess self-reported emotional intelligence cross-culturally as an input (attention to emotions), process (clarity of emotions), and output (repair of emotions) information-processing system. Iranian (N = 231) and American (N = 220) university students responded to the TMMS along with measures of alexithymia, public and private self-consciousness, depression, anxiety, self-esteem, and perceived stress. Negative correlations with alexithymia and expected linkages with all other variables documented the validity of the TMMS in both cultures. Most of the other measures correlated similarly in the two samples. However, private and public self-consciousness displayed a stronger positive association in Iran. These two scales were also more predictive of adjustment in Iran and of maladjustment in the United States. This difference perhaps reflected a poorer integration of the two dimensions of self-consciousness within a presumably more individualistic Amer.
Adaptive Signal Detection for Statistical Signal Transmission in Fast Time-Varying Channels

Statistical signal transmission (SST) is an emerging orthogonal frequency-division multiplexing (OFDM) technology that can carry additional information over conventional OFDM signal streams without extra bandwidth cost. This additional information can be exploited to carry control information, location/speed data, or cooperative schedule signals, etc., to improve the performance of wireless communications. However, existing detection methods used in this technique work-based mainly on time-invariant channels (i.e., channel state is quasi-static within a detection period), and cannot work well in diverse channel variations caused by different user velocities. In this paper, we propose a mobility adaptive detection method for SST. First, we analyze the influence of nonstatic channels on SST detection and identify a negative factor, called cyclic autocorrelation function whitening effect. Correspondingly, we probe the feasibility of antiwhitening concept and carry out relevant experiments for verification purpose. Based on this, a complete version of mobility adaptive detection method is proposed. Numerical results manifest that the proposed method outperforms the existing ones in high velocity scenarios. In addition, the properties of the proposed method are investigated, based on which we show a specific application for SST to reveal the potential for SST to be used in 5G wireless communications.
EVALUATION OF MICRODOSING STRATEGIES FOR STUDIES IN PRECLINICAL DRUG DEVELOPMENT: DEMONSTRATION OF LINEAR PHARMACOKINETICS IN DOGS OF A NUCLEOSIDE ANALOG OVER A 50-FOLD DOSE RANGE

The technique of accelerator mass spectrometry (AMS) was validated successfully and used to study the pharmacokinetics and disposition in dogs of a preclinical drug candidate (7-deaza-2'-C-methyl-adenosine; Compound A), after oral and intravenous administration. The primary objective of this study was to examine whether Compound A displayed linear kinetics across subpharmacological (microdose) and pharmacological dose ranges in an animal model, before initiation of a human microdose study. The AMS-derived disposition properties of Compound A were comparable to data obtained via conventional techniques such as liquid chromatography-tandem mass spectrometry and liquid scintillation counting analyses. Compound A displayed multiphasic kinetics and exhibited low plasma clearance (5.8 ml/min/kg), a long terminal elimination half-life (17.5 h), and high oral bioavailability (103%). Currently, there are no published comparisons of the kinetics of a pharmaceutical compound at pharmacological versus subpharmacological doses using microdosing strategies. The present study thus provides the first description of the full pharmacokinetic profile of a drug candidate assessed under these two dosing regimens. The data demonstrated that the pharmacokinetic properties of Compound A following dosing at 0.02 mg/kg were similar to those at 1 mg/kg, indicating that in the case of Compound A, the pharmacokinetics in the dog appear to be linear across this 50-fold dose range. Moreover, the exceptional sensitivity of AMS provided a pharmacokinetic profile of Compound A, even after a microdose, which revealed aspects of the disposition of this agent that were inaccessible by conventional techniques.
Outcome of domiciliary nasal intermittent positive pressure ventilation in restrictive and obstructive disorders.

BACKGROUND--Nasal intermittent positive pressure ventilation (NIPPV) is a new technique which has rapidly supplanted other non-invasive methods of ventilation over the last 5-10 years. Data on its effectiveness are limited. METHODS--The outcome of long term domiciliary NIPPV has been analysed in 180 patients with hypercapnic respiratory failure predominantly due to chest wall restriction, neuromuscular disorders, or chronic obstructive lung disease. One hundred and thirty eight patients were started on NIPPV electively, and 42 following an acute hypercapnic exacerbation. Outcome measures were survival (five year probability of continuing NIPPV), pulmonary function, and health status. A crossover study from negative pressure ventilation to NIPPV was carried out in a subgroup of patients. RESULTS--Five year acturial probability of continuing NIPPV for individuals with early onset scoliosis (n = 47), previous poliomyelitis (n = 30), following tuberculous lung disease (n = 20), general neuromuscular disorders (n = 29), and chronic obstructive pulmonary disease (n = 33) was 79% (95% CI 66 to 92), 100%, 94% (95% CI 83 to 100), 81% (95% CI 61 to 100), 43% (95% CI 6 to 80), respectively. Most of the patients with bronchiectasis died within two years. One year after starting NIPPV electively the mean (SD) PaO2 compared with the pretreatment value was +1.8 (1.9) kPa, mean PaCO2 -1.4 (1.3) kPa in patients with extrapulmonary restrictive disorders, and PaO2 +0.8 (1.0) kPa, PaCO2 -0.9 (0.8) kPa in patients with obstructive lung disease. Arterial blood gas tensions improved in patients transferred from negative pressure ventilation to NIPPV. Health status was ranked highest in patients with early onset scoliosis, previous poliomyelitis, and following tuberculous lung disease. In the group as a whole health perception was comparable to outpatients with other chronic disorders. CONCLUSIONS--The long term outcome of domiciliary NIPPV in patients with chronic respiratory failure due to scoliosis, previous poliomyelitis, and chest wall and pulmonary disease secondary to tuberculosis is encouraging. The results of NIPPV in patients with COPD and progressive neuromuscular disorders show benefit in some subgroups. The outcome in end stage bronchiectasis is poor.
Putting the ‘theory’ back into grounded theory: guidelines for grounded theory studies in information systems

Over the past decade, there has been increasing interest in the use of grounded theory in information systems research. Grounded theory is a qualitative research method that seeks to develop theory that is grounded in data systematically gathered and analysed. The purpose of this paper is to suggest guidelines for grounded theory studies in information systems. Our guidelines are based on a framework for theorizing in grounded theory studies that focuses on conceptualization and theory scope. Our hope is that the guidelines will help to raise the quality and aspirations of grounded theory studies in information systems.
Explaining English Language Proficiency Among Adolescent Immigrant Students

This study aims to increase understanding of factors that account for academic English language proficiency in a sample of 274 adolescent first-generation immigrant students from China, the Dominican Republic, Haiti, Central America, and Mexico. Previous research has shown the importance of English language proficiency in predicting academic achievement measured by GPA and achievement tests. The present study describes the academic English language proficiency of immigrant youth after, on average, 7 years in the United States and models factors that contribute to variation. Findings show that although differences in individual student characteristics partially explain variation in English language proficiency, the schools that immigrant youth attended are also important. The amount of time that students spent speaking English in informal social situations is predictive of English language proficiency. These findings demonstrate that social context factors directly affect language learning among adolescent immigrant youth and suggest a crucial role for school and peer interventions.
Migraine headache in middle age and late-life brain infarcts.

CONTEXT Migraine is considered to be an episodic condition with no long-term consequences. However, recent studies suggest that migraine attacks may be associated with pathologic changes in the brain, particularly in the cerebellum. OBJECTIVE To determine whether individuals not reporting headache compared with individuals reporting migraine symptoms, particularly aura, in midlife are at increased risk of late-life infarct-like lesions found on magnetic resonance imaging (MRI) without consideration of clinical symptoms. DESIGN, SETTING, AND PARTICIPANTS A population-based study of men and women in Reykjavik, Iceland (cohort born 1907-1935; n = 4689; 57% women) were followed up since 1967, examined, and interviewed about migraine symptoms in midlife (mean age, 51 years; range, 33-65 years). Between 2002 and 2006, more than 26 years later, brain MRIs were performed. Participants reporting headaches once or more per month were asked about migraine symptoms including nausea, unilateral location, photophobia, visual disturbance, and numbness. These individuals with headache were classified as having migraine without aura, migraine with aura, or nonmigraine headache. A comprehensive cardiovascular risk assessment was performed at both examinations. MAIN OUTCOME MEASURE Presence of infarct-like lesions (total) and specifically located in the cortical, subcortical, and cerebellar regions. RESULTS Infarct-like lesions were present in 39.3% of men and 24.6% of women. After adjusting for age, sex, and follow-up time, compared with those not reporting headaches once or more per month (n = 3243), those with midlife migraine with aura (n = 361) had an increased risk of late-life infarct-like lesions (adjusted odds ratio [OR], 1.4; 95% confidence interval [CI], 1.1-1.8) that specifically reflected an association with cerebellar lesions in women (prevalence of infarcts 23.0% for women with migraine with aura vs 14.5% for women not reporting headaches; adjusted OR, 1.9; 95% CI, 1.4-2.6 vs a 19.3% prevalence of infarcts for men with migraine with aura vs 21.3% for men not reporting headaches; adjusted OR, 1.0; 95% CI, 0.6-1.8; P<.04 for interaction by sex). Migraine without aura and nonmigraine headache were not associated with an increased risk. CONCLUSIONS Migraine with aura in midlife was associated with late-life prevalence of cerebellar infarct-like lesions on MRI. This association was statistically significant only for women. This is consistent with the hypothesis that migraine with aura in midlife is associated with late-life vascular disease in the cerebellum and in women.
Conceptualizing and Measuring a Power/Interaction Model of Interpersonal Influence1

In response to new theoretical conceptualizations (Raven, 1992, 1993), an instrument was developed to measure 11 bases of power, the original 6 French and Raven (1959; Raven, 1965) bases of power, with 3 of these further differentiated: reward (personal, impersonal), coercion (personal. impersonal), legitimate (position, reciprocity, equity, dependence), expert, referent, and information. In Study 1, 317 American student respondents rated the likelihood that each of these power bases contributed to a supervisor successfully influencing a subordinate in a series of hypothetical situations. The internal consistency of the items which made up the 11 power bases proved adequate. Factor analysis found 7 factors and 2 categories of bases: harsh and soft. In Study 2, which used 101 Israeli health workers, the earlier findings were generally supported. In addition, job satisfaction was found to be positively related to the attribution of soft bases to the supervisor.
Neuropsychological and adaptive functioning in younger versus older children shunted for early hydrocephalus

Abstract Previous research on children with hydrocephalus has not carefully examined age-related changes in neuropsychological and behavioral status. We present data on 28 children with early hydrocephalus and spina bifida who were studied in two age groups: 5 - 7.5 and 9 - 12.5 years. Age-related differences in language, memory, visuomotor skills, and adaptive behaviors were examined. Consistent with other studies, the total sample showed impaired motor, performance, verbal, communication, and learning skills. Comparisons between older and younger children showed: (1) except for memory, neuropsychological patterns of functioning were generally comparable across the age groups, and (2) older children demonstrated more difficulty on specific adaptive functions (socialization, learning, conduct). Shunted hydrocephalic children may be conceptualized as exhibiting the syndrome of nonverbal learning disabilities. Clinical implications are discussed.
