The present research examined the idea that the effectiveness of apologies on promoting fairness perceptions depends on how meaningful and sincere the apology is experienced. More precisely, it was predicted that apologies are more effective when they are communicated by an authority being respectful to others. A study using a cross-sectional organizational survey showed that an apology (relative to giving no apology) revealed higher fairness perceptions, but only so when the authority was respectful rather than disrespectful. In a subsequent experimental laboratory study the same interaction effect (as in Study 1) on fairness perceptions was found. In addition, a similar interaction effect also emerged on participants’ self-evaluations in terms of relational appreciation (i.e., feeling valued and likeable). Finally, these self-evaluations accounted (at least partly) for the interactive effect on fairness perceptions.

OBJECTIVETo compare the effectiveness of manual and automated methods for cleaning laparoscopic instruments.DESIGNExperimental laboratory study.METHODSWe evaluated 4 methods of cleaning laparoscopic instruments: (1) manual-only cleaning and rinsing with potable tap water; (2) manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning without rinsing; (3) manual cleaning and rinsing with potable tap water followed by ultrasonic cleaning and rinsing with potable tap water; and (4) manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning and rinsing: first with potable tap water and then with sterile distilled water. Organic residues of protein, hemoglobin, and carbohydrates were evaluated using spectrophotometry.RESULTSThe various cleaning methods tested did not result in statistically significant differences (P>.05) in the levels of investigated organic residues.CONCLUSIONSAll cleaning and rinsing methods tested were found to be effective in reducing the levels of organic residues on laparoscopic instruments. Thus, there is no advantage gained by supplementing manual-only cleaning with automated ultrasonic cleaning, nor was there a difference between rinsing with potable tap versus sterile distilled water.Infect Control Hosp Epidemiol 2018;39:58–63

Gas Properties

This paper describes a theory for a piston-operated compressor in which shock waves are used to heat the gas being compressed. Detailed calculations are given showing the use of such a compressor to heat air for use in a hypersonic wind tunnel. The effect of real gas properties on the compression process is included in this discussion.
