Female substance abusers recruited from the community were randomly assigned to receive 1 of 3 brief interventions that differentially targeted their personality and reasons for drug use. The 90-min interventions were: (a) a motivation-matched intervention involving personality-specific motivational and coping skills training, (b) a motivational control intervention involving a motivational film and a supportive discussion with a therapist, and (c) a motivation-mismatched intervention targeting a theoretically different personality profile. Assessment 6 months later (N?=?198) indicated that only the matched intervention proved to be more effective than the motivational control intervention in reducing frequency and severity of problematic alcohol and drug use and preventing use of multiple medical services. These findings indicate promise for a client-treatment matching strategy that focuses on personality-specific motives for substance abuse.

Drift is a common phenomenon in active sensors and, if left untreated, is generally the limiting factor in their performance. It is shown that drift and spread in sensor characteristics are tightly interwoven due to finite sensitivity to biasing parameters. Modern treatments of drift are dynamical under operating conditions, notably so chopping, the sensitivity variation method and the recently introduced van Putten-method. These methods differ in regards to drift-dependence on biasing. In their application to silicon flow sensors, the first two reduce but do not eliminate drift. The geometric van Putten-method leaves biasing invariant, which eliminates drift and obtains uniform sensor-characteristics leaving drift-free operation. 相似文献

Across 2 experiments, the authors demonstrate that emotional states influence how receptive people are to advice. The focus of these experiments is on incidental emotions, emotions triggered by a prior experience that is irrelevant to the current situation. The authors demonstrate that people who feel incidental gratitude are more trusting and more receptive to advice than are people in a neutral emotional state, and people in a neutral state are more trusting and more receptive to advice than are people who feel incidental anger. In these experiments, greater receptivity to advice increased judgment accuracy. People who felt incidental gratitude were more accurate than were people in a neutral state, and people in a neutral state were more accurate than were people who felt incidental anger. The results offer insight into how people use advice, and the authors identify conditions under which leaders, policy makers, and advisors may be particularly influential.

ELECTROLESS METALLIZATION of insulatingmaterials is currently used in industry since severaldecades.In its most common applications it consists ina redox reaction between Ni(+2)or Cu(+2)ions and astrong reducer(respectively hypophosphite,H2PO2,forNi(+2)and formaldehyde,HCHO,for Cu(+2))bothcontained in the same solution.The reaction initiationis generally catalyzed by palladium,then the redoxreaction goes on thanks to the remarkable property ofNi and Cu in their metallic state to … 相似文献

The computational modeling programs described in part II of this series are used in two ways. One is to compare program predictions
to previous experimental data, thereby testing to some extent the utility of the programs. At this stage of their development,
program “predictions” with respect to processing time, microstructural scale, and similar parameters are accurate to within
a factor of 2 or so. Even so, the predictions offer support of the model developed in part I of this series and provide a
vehicle for both model and process refinements. In addition to “testing” the model and the program in these manners, the effect
of uncertainty in input material properties on program predictions is explored.

A thoroughly tested, high-temperature channel-die compression (CDC) rig is described for simulating hot plane strain compression
of metallic alloys up to 500 °C. The equipment is currently used to characterize the flow stress and microstructure evolution
in hot-rolled Al alloys. It has been validated by several tests involving (1) metallographic analysis of deformed samples;
(2) flow stress comparisons with the same, or similar alloys deformed in conventional uniaxial or plane strain compression;
and (3) microstructure and texture measurements. The use of modern lubricants enables one to obtain accurate flow stresses
and true plane strain deformations that are homogeneous over 80 pct of the sample. The equipment also features rapid heating
and cooling systems to minimize thermally-induced microstructure changes. Some results on high-temperature slip systems, hot
deformation textures, and microstructures, and the behavior of constituent particles are outlined to illustrate the advantages
of the technique. 相似文献
