Age and sex effects for emotional intensity.

Examined age and sex trends in emotional intensity in 432 Ss from adopting and nonadopting biological families. It was hypothesized that younger adults and females would report greater average levels of both positive and negative affect over time, as has been demonstrated in past research. 242 Ss (parents and offspring) completed a battery of mood scales. 190 Ss completed an affect intensity measure and a general behavior inventory. In support of the hypothesis, women scored higher on measures reflecting emotional intensity and manifestation of cyclothymic symptoms, and the scores on these measures decreased through the adult life span for both males and females. Potential reasons for the differences in emotional intensity are discussed. These include biological causes, cultural expectations, and current life experiences.

Resources, personal strivings, and subjective well-being: A nomothetic and idiographic approach.

The covariation of resources such as money, family support, social skills, and intelligence with subjective well-being (SWB) was assessed in 195 college students. Informant ratings provided an index of resources. Self-reports, daily experience sampling, and informant reports were used to measure SWB. The authors concluded that resources taken together are moderately strong predictors of SWB. This conclusion, however, was qualified by the fact that life satisfaction was more closely related to resources than was affective well-being and that social and personal resources were in general more strongly related to SWB than were material resources. The findings also supported the hypothesis that resources correlate more strongly with SWB when they are relevant to an individual's idiographic personal strivings. A tendency was found for people to choose personal strivings for which they have relevant resources, and the degree of congruence of individuals' goals with resources was predictive of SWB.

Deindividuation, self-awareness, and disinhibition.

Assessed whether lack of self-awareness and conscious planning, group unity, and disinhibited behavior occurred together in deindividuating settings as predicted by E. Diener's (1979) theory of deindividuation. The characteristics and effects of group-induced deindividuation with non-socially-induced non-self-awareness was also compared. The 3 conditions were deindividuated, non-self-aware, and self-aware. After the manipulations, 126 undergraduates chose inhibited vs disinhibited tasks in a supposed "creativity" session, followed by a variety of deindividuation measures. Results reveal that the deindividuation group surpassed the other 2 on the deindividuation factor and on most of the individual measures. For some of the variables, the deindividuation and non-self-aware groups differed significantly, suggesting that deindividuation may not be identical in every respect to lack of self-awareness induced in a non-social way.

Highy oblique impacts into thick and thin targets

Hypervelocity impact (HVI) tests have been conducted at the JSC Hypervelocity Impact Test Facility (HIT-F) with aluminum projectiles impacting semi-infinite (thick) and thin aluminum plates (with plate thickness to projectile diameter ratios of 6.4 and 0.14, respectively) at impact angles ranging from normal to the plate (0°) to highly oblique (88°). The targets were impacted by solid homogeneous aluminum spheres from 1 mm to 3.6 mm diameter. Results of the HVI tests were not unusual up to 65°, where impact damage is characterized as smooth craters and holes that become progressively elliptical and distended along the projectile flight path. Above 65° angles, however, a transition occurs to an irregularly shaped hole in thin materials and rough bottomed crater in thick targets. Above 80°, multiple damage sites in the targets were formed with the damage areas separated by variable distances of undamaged target surface. Analytical and numerical simulations of the impact process at oblique angles above 65° demonstrates that shock compression and release of the projectile into multiple fragments occurs before the projectile fully engages the target. The resulting projectile fragments are then responsible for the multiple impact sites observed on the targets.     

Discriminant validity of well-being measures.

The convergent and discriminant validities of well-being concepts were examined using multitrait-multimethod matrix analyses (D. T. Campbell & D. W. Fiske, 1959) on 3 sets of data. In Study 1, participants completed measures of life satisfaction, positive affect, negative affect, self-esteem, and optimism on 2 occasions 4 weeks apart and also obtained 3 informant ratings. In Study 2, participants completed each of the 5 measures on 2 occasions 2 years apart and collected informant reports at Time 2. In Study 3, participants completed 2 different scales for each of the 5 constructs. Analyses showed that (a) life satisfaction is discriminable from positive and negative affect, (b) positive affect is discriminable from negative affect, (c) life satisfaction is discriminable from optimism and self-esteem, and (d) optimism is separable from trait measures of negative affect.

On the minimal realization of the gyrator by means of nullors and resistors. II

It is proved that it is impossible to synthesize a gyrator with only two nullors and three resistors. Combining the results obtained in References 1 and 2 and in this paper, we obtain the following necessary and sufficient conditions: a nullor-resistor gyrator realization is minimal if and only if it consists of either two nullors and four resistors or three nullors and two resistors.     

Parallel and adaptive high-resolution direction finding

Recently the new class of so-called subspace methods for high-resolution direction finding has received a great deal of attention in the literature. When a real-time implementation is aimed at, the computational complexity involved is known to represent a serious impediment. In this paper, an ESPRIT-type algorithm is developed, which is fully adaptive and therefore particularly suited for real-time processing. Furthermore, a systolic array is described, which allows the processing of incoming data at a rate which is independent of the problem size. The algorithm is based on orthogonal transformations only. Estimates are computed for the angles of arrival, as well as for the source signals. Our aim is not so much to develop yet another ESPRIT-type algorithm but rather to show that it is indeed possible to develop an algorithm that is fully parallel and adaptive. This is something that has not been done before
