In this paper, the problem of time to recruitment is analyzed for a single grade manpower system using an univariate CUM policy of recruitment. Assuming policy decisions and exits occur at different epochs, wastage of manpower due to exits form a sequence of independent and identically distributed exponential random variables, the inter-decision times form a geometric process and inter-exist time form an independent and identically distributed random variable. The breakdown threshold for the cumulative wastage of manpower in the system has three components which are independent exponential random variables. Employing a different probabilistic analysis, analytical results in closed form for system characteristics are derived

The formation of shadows behind small particles has been thought to be a geometric process (GP) where the metal cap build up on the particle creates a shadow width the same size as or larger than the particle. This GP cannot explain why gold particle shadow widths are generally larger than the gold particle and may have no appreciable metal cap build up (fig. 1). Ruben and Telford have suggested that particle shadow widths are formed by the width dependent deflection of shadow metal (SM) lateral to and infront of the particle. The trajectory of the deflected SM is determined by the incoming shadow angle (45°). Since there can be up to 1.4 times (at 45°) more SM directly striking the particle than the film surface, a ridge of metal nuclei lateral to and infront of the particle can be formed. This ridge in turn can prevent some SM from directly landing in the metal free shadow area. However, the SM that does land in the shadow area (not blocked by the particle or its ridge) does not stick and apparently surface migrates into the SM film behind the particle.

This study deals with the sociocognitive organization of the self-schema in alcoholic patients. It was aimed at understanding how the self-schema takes shape within the framework of social judgments known to be determinants of personality. Alcoholic subjects were interviewed twice, once during their first consultation for treatment and then again four months later after completion of treatment. Our approach was derived directly from the methodology used by Markus (1977) and Clemmey & Nicassio (1997) in their studies on the self-schema. The subjects had to perform three tasks that required manipulating personality traits with positive and negative connotations (a self-description task in which decision time was measured, an autobiographical task, and a recall task). The results of the first interview showed that 1. in their self-descriptions, alcoholics took more time than control subjects both to accept positive traits and to reject negative ones; 2. unlike control subjects, alcoholics considered more negative traits to be self-descriptive than positive traits, and 3. unlike controls, alcoholics recalled more negative traits than positive ones. By the second interview, the results for the alcoholic subjects on the autobiographical and recall tasks had changed: 1. they now described themselves more positively and less negatively than on the first meeting; 2. they recalled a marginally greater number of positive traits and a significantly smaller number of negative traits, and 3. the differences between the alcoholics and controls indicated an improvement in the alcoholics' self-perceptions.

Research using the Implicit Association Test (IAT) has shown that names labeled as Caucasian elicit more positive associations than names labeled as non-Caucasian. One interpretation of this result is that the IAT measures latent racial prejudice. An alternative explanation is that the result is due to differences in in-group/out-group membership. In this study, we conducted three different IATs: one with same-race Dutch names versus racially charged Moroccan names; one with same-race Dutch names versus racially neutral Finnish names; and one with Moroccan names versus Finnish names. Results showed equivalent effects for the Dutch-Moroccan and Dutch-Finnish IATs, but no effect for the Finnish-Moroccan IAT. This suggests that the name-race IAT-effect is not due to racial prejudice. A diffusion model decomposition indicated that the IAT-effects were caused by changes in speed of information accumulation, response conservativeness, and non-decision time.
