Optimization of Flexographic Water-Based Ink Formulation for Polymer Films

In this study, the optimization of flexographic water-based ink formulation was carried out. The aim is to minimize the contact angle of the ink on polymer substrates. A factorial design was used to evaluate the effects and interactions of three factors, which are dispersant, wetting agent and antifoam concentration on the wettability of ink. The optimal conditions obtained from the desirable response are dispersant of 9.65%, wetting agent of 0.58% and antifoam of 0.55 %. Under these conditions, about 15O of contact angle is obtained. The validity of the statistical experimental strategies was verified by the ink samples prepared under the optimized conditions.

Optimization of Technical Parameters on the Color Variation in offset Printing Process

In this study, the optimization of parameters of the printing process was carried out. The aim is to minimize the size of color variation in prints. A factorial design was used to evaluate the effects and interactions of three factors, that is, impression pressure, alcohol %, and press speed. The color variation is gauged by variation in ink transfer, which is governed by color difference (?E). The optimal conditions obtained from the desirable response are impression pressure of 0.15 mm, alcohol percentage of 12.2 % and press speed of 8500 sheets per hour. Under these conditions, about 0.62 of color difference is obtained.

“Let Me Show You How Nice I Am”: Impression Management as Bias in Empathic Responses

Past research showed that empathic responses are confounded with social desirability. The present research aims at illuminating this confound. In a first step, it is examined how a measure typically implemented to screen, for response, biases based on social desirability (i.e., the Balanced Inventory of Desirable Responding) relate to classical measures of interindividual differences in empathic responses (i.e., the Interpersonal Reactivity Index). Moreover, it is investigated what happens to empathic responses under conditions of reduced opportunity to behave socially desirable. Results of two correlational studies indicate that impression management (IM) as well as self-deceptive enhancement as facets of a socially desirable response bias is related to self-reported empathic responses. Results of an additional experiment show that introducing conditions reducing opportunity for IM lowers empathic responses toward a person in need. Implications for research on self-reported empathy and empathy-induced prosocial behavior are discussed.

From phonemic spelling to distinctive spelling

Whether spelling is phonemic is only one factor in whether a writing system is suitable for a given language; another consideration is "lexical distinctiveness" of spelling, in two separate senses, and the importance of lexical distinctiveness grows as a writing system matures. Seen in this light, the increasing irregularity of English spelling, over the period when English has been a written language, has been a desirable response to the changing needs of the English-speaking world.

Rushing towards virtue: time pressure increases socially desirable responding

The oldest method in psychology of trying to gain access to one part of a divided mind is to instruct participants to answer quickly. Here we propose an alternative account for this procedure, namely, that it makes people give the socially desirable response. We randomly assigned 1,500 Americans to answer a social desirability scale either quickly or slowly. We use an intention-to-treat analysis to test the effects quick vs. slow responding on social desirability. We show quick responding causes an increase in social desirability. We propose that a number of findings using the fast/slow responding manipulation can be partially or entirely explained by participants’ giving the socially desirable response. Future investigations using the time pressure manipulation should account for social desirability to ensure the results are not entirely driven by this mechanism.

Social Desirability and Undesirability Effects on Survey Response latencies

This article looks at paradata in the form of response latencies to identify socially desirable response behaviour. Response latencies are used as proxies to infer information processing modes. So far, evidence is conflicted as to whether socially desirable responding is indicated by shorter or longer response latencies. Our results show that faster responses are associated with the reporting of desirable attitudes and behaviour while slower responses are linked with those that are undesirable. Trait desirability measures that do not take this difference in direction into account may be responsible for the often contradictory results of various researchers who have employed the method in the past.
