Effects of sample bias on adhesion of magnetron sputtered Cr coatings on SiC

Abstract This article develops a two-stage statistical analysis to identify and assess the effect of a sample bias associated with an individual’s household role. Survey responses to questions about the respondent’s role in household finances and a sampling design in which some households have all members take the survey enable the estimation of distributions for each individual’s share of household responsibility. The methodology is applied to the 2017 Survey of Consumer Payment Choice. The distribution of responsibility shares among survey respondents suggests that the sampling procedure favors household members with higher levels of responsibility. A bootstrap analysis reveals that population mean estimates of monthly payment instrument use that do not account for this type of sample misrepresentation are likely biased for instruments often used to make household purchases. For checks and electronic payments, our analysis suggests that it is likely that unadjusted estimates overstate true values by 10–20 percent.

The structure of the UO 2+x (111) surface has been investigated by elevated temperature STM. Images of atomic terraces reveal two different types of surface termination. One of them corresponds to the stoichiometric UO 2 (111) surface and can be resolved atomically in empty state images above ~ 1.6 V sample bias. The observed (1 × 1) ordering is thought to be due to uranium states because its occurrence corresponds to the bottom of the empty uranium 5f band. On these terraces mobile oxygen forms a local [Formula: see text] superstructure. The other terrace type observed on top of the UO 2+x (111) surface is thought to be a phase of a higher uranium oxide which has grown epitaxially.

The Relationship

We performed STM measurements on the K/GaAs (110) surface with high K coverage. The K atoms gradually disappeared while scanning the tip over the surface at negative sample bias voltage. The phenomenon strongly occurred over the scanning area and can be explained by the field-induced surface diffusion from the scanning area to radial direction. Considering the interaction between the dipole moment of the adsorbed K atoms and the electric field, we discuss the relationship between the static and induced dipole moment of K atoms on a GaAs (110) surface.

Internal And External Validity

Attachment styles are often primed by having participants recall and describe a relationship that is prototypical of a given attachment style. Researchers may exclude participants who cannot recall such a relationship, or who describe relationships that do not conform to the assigned prime. I suggest that excluding participants is untenable, and may threaten a study’s validity. In the present research, I examine predictors of exclusion from an attachment priming study. Priming insecure attachment resulted in greater odds of exclusion relative to a control condition. Female participants with greater sexual experience also had lesser odds of exclusion. These results suggest that attachment-priming procedures contribute to participant exclusion that compromise internal and external validity. Discussion focuses on directions for future attachment-priming research.
