Curious enough to start up? How epistemic curiosity and entrepreneurial alertness influence entrepreneurship orientation and intention

Epistemic curiosity as the desire to acquire new knowledge and ideas is considered as an important attribute for successful entrepreneurs among practitioners, yet there is lacking empirical evidence of epistemic curiosity having an effect on entrepreneurial outcomes. This study aims to put a spotlight on epistemic curiosity as a predictor for entrepreneurial intentions and orientation. We found that epistemic curiosity has a stronger influence on entrepreneurial outcomes in comparison to the Big Five personality trait openness to experience, which is a widely used and conceptually related predictor for entrepreneurship. Furthermore, we found evidence for a mediating role of entrepreneurial alertness which gives further insights about how personality influences the ability to recognize business opportunities and leads to the formation of entrepreneurship orientation and intentions. Our findings contribute to the field of entrepreneurship research by emphasizing that epistemic curiosity may be one of the most important personality indicators for the emergence of entrepreneurial intentions and behavior

The influence of situational strength on the relation of personality and situational judgment test performance

Situational strength theory has been used as a theoretical underpinning of person–situation processes that are linked to job performance. Accordingly, the link between personality traits and job performance increases in weak situations. Building on this research, similar mechanisms have been proposed for simulation-based selection tools, such as Situational Judgment Tests (SJTs), to explain how these measures work as predictors of job performance. However, underlying processes of SJT performance are subject to debate with some scholars arguing in favor of context-independent processes while others maintain that situations play an essential role. This study (N = 707) examined whether the strength of situations in SJT items moderated the relation between personality and SJT performance. Results did not support the notion that personality is more strongly related to SJT performance when situations are weak. In fact, for some traits, the opposite may be true as more situational constraints led to an increase in the relation of extraversion, emotional stability, and SJT performance. The results add to an increasing body of research about psychological processes in SJTs. Limitations and implications for research and practice are discussed

The importance of situation construal for situational judgment test performance

Recent research challenges the importance of situation descriptions for situational judgment test (SJT) performance. This study contributes to resolving the ongoing debate on whether SJTs are situational measures, by incorporating findings on person × situation interactions into SJT research. Specifically, across three studies (NTotal = 1,239), we first tested whether situation construal (i.e., the individual perception of situations in SJTs) predicts responses to SJT items. Second, we assessed whether the relevance of situation construal for SJT performance depends on test elements (i.e., situation descriptions and response options) and item features (i.e., description‐dependent vs. description‐independent SJT items). Lastly, we determined whether situation construal has incremental validity for job‐related criteria over and above SJT performance. The results showed that, for most SJT items, situation construal significantly contributed to SJT performance, even if only response options were available. This was also true for SJT items that are significantly more difficult to solve when situation descriptions are omitted (i.e., description‐dependent SJT items). Finally, situation construal explained variance in relevant criteria over and above SJT performance. Despite recent efforts to reconceptualize SJTs, our results suggest that they can still be viewed as situational measures. However, situation descriptions may be less crucial for these underlying situational processes. Theoretical and practical implications are discussed

Does understanding what a test measures make a difference? On the relevance of the ability to identify criteria for situational judgment test performance

Situational judgment tests (SJTs) are low-fidelity simulations that are often used in personnel selection. Previous research has provided evidence that the ability to identify criteria (ATIC)—individuals' capability to detect underlying constructs in nontransparent personnel selection procedures—is relevant in simulations in personnel selection, such as assessment centers and situational interviews. Building on recent theorizing about response processes in SJTs as well as on previous empirical results, we posit that ATIC predicts SJT performance. We tested this hypothesis across two preregistered studies. In Study 1, a between-subjects planned-missingness design (N = 391 panelists) was employed and 55 selected items from five different SJTs were administered. Mixed-effects-modeling revealed a small effect for ATIC in predicting SJT responses. Results were replicated in Study 2 (N = 491 panelists), in which a complete teamwork SJT was administered with a high- or a low-stakes instruction and showed either no or a small correlation with ATIC, respectively. We compare these findings with other studies, discuss implications for our understanding of response processes in SJTs, and derive avenues for future research

Different Culture, Same Situation? Translating and Applying a Situational Judgment Test From Germany in Cuba

Situational judgment tests (SJTs) are popular instruments in selection and assessment. However, the application of SJTs to non-Western cultural contexts remains scarce. In this study, we investigated whether an SJT on personal initiative, developed in Germany and translated into Cuban Spanish, had similar psychometric properties in Cuba. Second, there is an ongoing debate about the extent to which the situation description plays an important role for SJTs. We supposed that the impact of situation descriptions might depend on test takers’ familiarity with the culture in which the SJT was developed. Hence, we tested whether the omission of situation descriptions had larger effects in a Cuban than in a German sample. We applied a 2 (with vs. without situation description in the item stem) × 2 (cultural background: Cuba vs. Germany) between-subjects design (NCuba = 192, NGermany = 213). The results revealed similar psychometric properties between Cuban and German test takers concerning measurement invariance, construct-related validity, and reliability. In addition, we examined whether samples differ regarding applicant perceptions: Notably, for four of six applicant perception scales, the Cuban sample reported a more positive view of the SJT. Furthermore, we found that the effect of situation availability on SJT performance did not substantially depend on the test takers’ cultural background. Implications for cross-cultural generalizability are discussed

Decompressive Craniectomy Is Associated With Good Quality of Life Up to 10 Years After Rehabilitation From Traumatic Brain Injury

OBJECTIVES Traumatic brain injury is the number one cause of death in children and young adults and has become increasingly prevalent in the elderly. Decompressive craniectomy prevents intracranial hypertension but does not clearly improve physical outcome 6 months after traumatic brain injury. However, it has not been analyzed if decompressive craniectomy affects traumatic brain injury patients' quality of life in the long term. DESIGN Therefore, we conducted a cross-sectional study assessing health-related quality of life in traumatic brain injury patients with or without decompressive craniectomy up to 10 years after injury. SETTING Former critical care patients. PATIENTS Chronic traumatic brain injury patients having not (n = 37) or having received (n = 98) decompressive craniectomy during the acute treatment. MEASUREMENTS AND MAIN RESULTS The Quality of Life after Brain Injury questionnaire was used as outcome measure with a total score from zero to 100, representing lowest and best health-related quality of life, respectively. Health-related quality of life was compared between patients with or without decompressive craniectomy for the entire cohort, for the traumatic brain injury severity (mild, moderate, severe) measured by the initial Glasgow Coma Scale, for age and time variables (age at traumatic brain injury, age at survey, elapsed time since traumatic brain injury) using the Mann-Whitney U test. Differences were considered significant at a p value of less than 0.05.Decompressive craniectomy was necessary in all initial traumatic brain injury severity groups. Eight percent more decompressive craniectomy patients reported good health-related quality of life with a Quality of Life after Brain Injury total score greater than or equal to 60 compared with the no decompressive craniectomy patients up to 10 years after traumatic brain injury (p = 0.004). Initially, mild classified traumatic brain injury patients had a median Quality of Life after Brain Injury total score of 83 (decompressive craniectomy) versus 62 (no decompressive craniectomy) (p = 0.028). Health-related quality of life regarding physical status was better in decompressive craniectomy patients (p = 0.025). Decompressive craniectomy showed a trend toward better health-related quality of life in the 61-85-year-old reflected by median Quality of Life after Brain Injury total scores of 62 (no decompressive craniectomy) versus 79 (decompressive craniectomy) (p = 0.06). CONCLUSIONS Our results suggest that decompressive craniectomy is associated with good health-related quality of life up to 10 years after traumatic brain injury. Thus, decompressive craniectomy may have an underestimated therapeutic potential after traumatic brain injury

The role of situations in situational judgment tests: Effects on construct saturation, predictive validity, and applicant perceptions

Recent theorizing and empirical evidence suggesting that Situational Judgment Tests (SDI's) are more context-independent than previously thought has sparked a debate about the role of situation descriptions in S.M. To contribute to this debate and add to our understanding of how SJTs work, this article conceptually embeds SJT performance in a situation construal model and examines the effects of situation descriptions on the construct saturation and predictive validity of SJT scores, as well as on applicant perceptions. Across two studies (N = 1,092 and 578) and different Sri's, personality and cognitive ability were equally important determinants of SJT performance regardless of whether situation descriptions were presented or omitted. The effects of removing situation descriptions on the criterion-related validity of SJT scores differed depending on the breadth of the criteria. For predicting global job performance criteria (in-role performance and organizational citizenship behavior), SJT validity was not significantly affected, whereas it decreased for predicting more specific criteria (interpersonal adaptability, efficacy for teamwork). Finally, the effects of omitting situation descriptions in SJTs on applicant perceptions were either negligible or small. Implications for SJT theory, research, and design are discussed

Single in situ Interface Characterization Composed of Niobium and a Selectively Grown (Bi1−x_{1-x}Sbx_x)2_2Te3_3 Topological Insulator Nanoribbon

With increasing attention in Majorana physics for possible quantum bit applications, a large interest has been developed to understand the properties of the interface between a $s$-type superconductor and a topological insulator. Up to this point the interface analysis was mainly focused on in situ prepared Josephson junctions, which consist of two coupled single interfaces or to ex-situ fabricated single interface devices. In our work we utilize a novel fabrication process, combining selective area growth and shadow evaporation which allows the characterization of a single in situ fabricated Nb/$\mathrm{(Bi_{0.15}Sb_{0.85})_2Te_3}$ nano interface. The resulting high interface transparency is apparent by a zero bias conductance increase by a factor of 1.7. Furthermore, we present a comprehensive differential conductance analysis of our single in situ interface for various magnetic fields, temperatures and gate voltages. Additionally, density functional theory calculations of the superconductor/topological insulator interface are performed in order to explain the peak-like shape of our differential conductance spectra and the origin of the observed smearing of conductance features.Comment: Main manuscript: 11 pages, 6 figures, Supplementary material: 10 pages, 9 figure
