Judgment Strategy

Judging other people is a common and important task. Every day professionals make decisions that affect the lives of other people when they diagnose medical conditions, grant parole, or hire new employees. To prevent discrimination, professional standards require that decision makers render accurate and unbiased judgments solely based on relevant information. Facial similarity to previously encountered persons can be a potential source of bias. Psychological research suggests that people only rely on similarity-based judgment strategies if the provided information does not allow them to make accurate rule-based judgments. Our study shows, however, that facial similarity to previously encountered persons influences judgment even in situations in which relevant information is available for making accurate rule-based judgments and where similarity is irrelevant for the task and relying on similarity is detrimental. In two experiments in an employment context we show that applicants who looked similar to high-performing former employees were judged as more suitable than applicants who looked similar to low-performing former employees. This similarity effect was found despite the fact that the participants used the relevant résumé information about the applicants by following a rule-based judgment strategy. These findings suggest that similarity-based and rule-based processes simultaneously underlie human judgment.

Talent Retention

Talent retention and employee turnover are major concerns for higher education institutions (HEIs) because they are losing highly qualified staff to the private sector and to other HEIs that are able to offer better rewards and benefits. The turnover of talented staff is therefore a major concern for the institution under investigation. The retention and voluntary turnover decisions among a workforce of 4 651 employees was thus investigated. A quantitative cross-sectional study was conducted by means of the objective analysis of organisational data in combination with the structured questionnaire (organisational climate survey). Descriptive and inferential statistics were applied to analyse the data across demographic groups, including age, employment category (academic as well as professional and support), etc. The results indicated that the institution’s turnover rate was acceptable (4.34%) and that dysfunctional turnover was marginal because employees with below-standard performance ratings had voluntarily resigned. Positive correlations and significant beta (b) values were reported between Organisational citizenship, Leadership, My manager and Compensation and the employees’ intent to stay in or to leave the organisation. These organisational climate factors were found to explain approximately 30 per cent of the variance in the employees’ intent to stay in or to leave the organisation. The article recommends that a talent retention tool be developed. In addition, it contributes to the literature on retention and turnover of high-performing employees, as it underscores the importance of measuring employee turnover

The Given

<p>Sulfidic sodium ion conductors are currently investigated for the possible use in all-solid-state sodium ion batteries. The design of high performing electrolytes in terms of temperature-dependent ionic transport is based upon the fundamental understanding of structure – transport relationships within the given structural phase boundaries inherent to the investigated materials class. In this work, the Na<sup>+</sup> superionic structural family of Na<sub>11</sub>Sn<sub>2</sub>PS<sub>12</sub> is explored by using the systematic antimony substitution with phosphorous in Na<sub>11+<i>x</i></sub>Sn<sub>2+<i>x</i></sub>(Sb<sub>1-<i>y</i></sub>P<i><sub>y</sub></i>)<sub>1-<i>x</i></sub>S<sub>12</sub>. A combination of Rietveld refinements against X-ray synchrotron diffraction data with electrochemical impedance spectroscopy is used to monitor the changes in the anionic framework, the Na<sup>+</sup> substructure and the ionic transport. A new simplified descriptor for the average Na<sup>+</sup> diffusion pathways, the average Na<sup>+</sup> polyhedral volume is introduced, which is used to correlate the contraction of the overall lattice and the found activation barriers in the system. This study exemplifies how substitution affects diffusion pathways in ionic conductors and widens the knowledge about the related structural motifs and their influence on the ionic transport in this novel class of ionic conductors.</p>
