Rich Dad Poor Dad? CEO Private School Background and Firm Risk
European Financial Management, EarlyView.ABSTRACT We examine the effect of CEO childhood socioeconomic status (SES) on firm risk. Using hand‐collected data on US CEOs' private high‐school attendance as proxy for high‐SES, we find that firms led by high‐SES CEOs exhibit 5.35% lower firm risk. This effect diminishes with CEO tenure, analyst coverage, and institutional ownership, consistent with

Ibis, EarlyView.Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

On Generalizations of the Pell Sequence
, 2017 In this paper, we investigate the generalized Pell sequence, the generalized complex Pell sequence and the generalized dual Pell sequence using the Pell numbers. We obtain special cases of these sequences. Furthermore, we give recurrence relations, vectors, the silver ratio and Binet's formula for the above-investigated sequences.

On hyperbolic k-Pell quaternions sequences [PDF]
Annales Mathematicae et Informaticae, 2018 Summary: In this paper we introduce the hyperbolic $k$-Pell functions and new classes of quaternions associated with this type of functions are presented. In addition, the Binet formulas, generating functions and some properties of these functions and quaternions sequences are studied.

Markov Triples with Generalized Pell Numbers
Mathematics, 2023 For an integer k≥2, let (Pn(k))n be the k-generalized Pell sequence which starts with 0,…,0,1 (k terms), and each term afterwards is given by Pn(k)=2Pn−1(k)+Pn−2(k)+⋯+Pn−k(k). In this paper, we determine all solutions of the Markov equation x2+y2+z2=3xyz,

Transferring Competences to the Workplace Through Gamified Training: A Case Study
International Journal of Training and Development, EarlyView.ABSTRACT This study examines the transfer of gamified training activities aimed at developing key workplace competences, focusing on creativity, innovation and decision‐making within a specific organisational context. We conducted an exploratory case study in a Spanish public‐sector organisation.

The Generating Functions for Special Pringsheim Continued Fractions
Communications in Advanced Mathematical Sciences, 2020 In previous works, some relations between Pringsheim continued fractions and vertices of the paths of minimal length on the suborbital graphs $\mathrm{\mathbf{F}}_{u,N}$ were investigated.

Escape Body: A Gamified Problem‐Based Learning Project in Primary Education
School Science and Mathematics, EarlyView.ABSTRACT Young learners' lack of motivation to study scientific‐related subjects nowadays is a topic of concern in our society. This study followed a quasi‐experimental design with a predominantly quantitative methods approach, complemented by qualitative data, to investigate how the combination of gamified and problem‐based learning could influence ...

The Properties of the Altered Pell and Pell Lucas Sequences
Iğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 The altered Pell and Pell Lucas sequences are defined by altering the Pell and Pell Lucas numbers, it is seen that they have similar properties to usual the Pell and Pell Lucas sequences. Thus, we study some recursive properties of the altered sequences. Further, the greatest common divisors (i.e.

International Journal of Cancer, Volume 159, Issue 6, Page 1420-1431, 15 September 2026.Evidence suggests a potential association between mental health conditions and cancer risk, yet previous studies were limited by small samples and the use of self‐reported measures. Using data from the UK Biobank's large‐scale prospective population cohort over a median follow‐up of 13.4 years, this analysis demonstrates associations between depression,
