NUMERACY AND ON-THE-JOB PERFORMANCE: EVIDENCE FROM LOAN OFFICERS

We examine how the numeracy level of employees influences their on-the-job performance. Based on an administrative dataset of a retail bank we relate the performance of loan officers in a standardized math test to the accuracy of their credit assessments of small business borrowers. We find that loan officers with a high level of numeracy are more accurate in assessing the credit risk of borrowers. The effect is most pronounced during the precrisis credit boom period when it is arguably more difficult to pick out risky borrowers. (JEL G21, J24)     

Service user and carer feedback: simply pass/fail or a genuine learning tool?

Social Work Students in Britain are required to submit feedback from Service Users and Carers as part of their Practice Learning portfolios. The purpose of this is twofold—to demonstrate evidence of the student’s ability and to provide information for the student to reflect on and learn from. Members of the Service User and Carer Advisory group attached to a Social Work degree course believe this represents an opportunity for users and carers to influence future social work practice. In reality however, does this feedback actually make a difference? Group members reviewed user and carer feedback contained within student portfolios submitted during one academic year. They found that whilst there were some excellent examples of constructive criticism, the feedback was overwhelmingly positive towards students. The findings raised questions about how gathering Service User and Carer feedback is viewed and undertaken. Is the feedback seen more as a pass/fail issue or as an opportunity to learn from? Could there be better ways to gain constructive feedback for students? What conditions enable students to learn from the feedback that is gathered? This paper starts to explore these questions and suggests ideas for further research and training.     

The fertility integration of Mexican-Americans across generations: confronting the problem of the ‘third’ generation*

The manner in which ‘third generation’ Mexican-Americans are identified, predicated on self-reported ethnic identity rather than grandparental nativity, is imprecise and potentially confounded with later generations. This study examines the degree to which this imprecision accounts for the stagnation found in many past studies of integration, including fertility integration. We use data from the study Immigration and Intergenerational Mobility in Metropolitan Los Angeles (IIMMLA), which includes questions on grandparental nativity, to construct a better-defined third generation. When IIMMLA data are aggregated into the commonly measured third-plus generation, the findings show a pattern of slow intergenerational-fertility integration, similar to previous research using the Current Population Survey or other data with third-plus generation measures. However, when we consider a third generation identified by grandparental nativity, evidence emerges of a faster fertility decline, bringing the third generation's fertility more in line with the native-born population as a whole. The results suggest that conclusions about integration based on third-plus generation measures should be regarded with greater scepticism and support efforts to include in surveys questions on grandparental nativity to enable the isolation of a genuine third generation among ethnic groups with immigrant origins.     

The promise and pitfalls of composite endpoints in sepsis and COVID-19 clinical trials

Composite endpoints reveal the tendency for statistical convention to arise locally within subfields. Composites are familiar in cardiovascular trials, yet almost unknown in sepsis. However, the VITAMINS trial in patients with septic shock adopted a composite of mortality and vasopressor-free days, and an ordinal scale describing patient status rapidly became standard in COVID studies. Aware that recent use could incite interest in such endpoints, we are motivated to flag their potential value and pitfalls for sepsis research and COVID studies.

#wheresRey: feminism,protest, and merchandising sexism in Star Wars: The Force Awakens

The blockbuster film Star Wars: The Force Awakens (2015) earned over $2 billion dollars at the box-office worldwide and became a cultural phenomenon. Produced by media giant Disney, The Force Awakens also generated huge merchandising sales and earned over $9 billion within a year. The film’s main protagonist, Rey, was heralded as a strong, feminist-influenced heroine that capably carved her own space within the male dominated Star Wars universe. Unfortunately, the inherent sexism of the film’s marketing strategy meant that Rey was excluded from the merchandising line. Consumers protested Rey’s absence and demonstrated the importance of popular culture within the realm of political protests about gender equality and commercialization, ultimately leading to industrial and social change.     

The development of gaze following in monolingual and bilingual infants: A multi-laboratory study

Determining the meanings of words requires language learners to attend to what other people say. However, it behooves a young language learner to simultaneously encode relevant non-verbal cues, for example, by following the direction of their eye gaze. Sensitivity to cues such as eye gaze might be particularly important for bilingual infants, as they encounter less consistency between words and objects than monolingual infants, and do not always have access to the same word-learning heuristics (e.g., mutual exclusivity). In a preregistered study, we tested the hypothesis that bilingual experience would lead to a more pronounced ability to follow another's gaze. We used a gaze-following paradigm developed by Senju and Csibra (Current Biology, 18, 2008, 668) to test a total of 93 6- to 9-month-old and 229 12- to 15-month-old monolingual and bilingual infants, in 11 laboratories located in 8 countries. Monolingual and bilingual infants showed similar gaze-following abilities, and both groups showed age-related improvements in speed, accuracy, frequency, and duration of fixations to congruent objects. Unexpectedly, bilinguals tended to make more frequent fixations to on-screen objects, whether or not they were cued by the actor. These results suggest that gaze sensitivity is a fundamental aspect of development that is robust to variation in language exposure.
