Abstract This article examines the factors associated with persistent absenteeism (an absence rate of 10% or higher) and authorised and unauthorised absence among secondary school pupils in Scotland. Using linked administrative data, the analysis focuses on secondary school stages S1–S6 in three academic years.

Asymptotic Expansions of Central Binomial Coefficients and Catalan Numbers
We give a systematic view of the asymptotic expansion of two well-known sequences, the central binomial coefficients and the Catalan numbers. The main point is explanation of the nature of the best shift in variable $n$, in order to obtain ``nice'' asymptotic expansions. We also give a complete asymptotic expansion of partial sums of these sequences.

Congruences involving the reciprocals of central binomial coefficients
We present several congruences modulo a power of prime $p$ concerning sums of the following type $\sum_{k=1}^{p-1}{m^k\over k^r}{2k\choose k}^{-1}$ which reveal some interesting connections with the analogous infinite series.

Is the binomial coefficient $2n \choose n$ square free?
In this paper, we prove the Erd\"os conjecture that the binomial coefficient ${2n \choose n}$ is never square free, for all $n>4$

Breaking point: Identifying the factors that predict suspension from school
Abstract School suspensions are associated with adverse educational and psychosocial outcomes, yet little is known about how structural disadvantage, relational factors, health behaviours, well‐being indicators and school‐level factors jointly predict suspension risk in England.

Généralisations du coefficient binomial de mots [PDF]
Binomial coefficients of natural numbers are ubiquitous in mathematics and have a rich and fascinating history. Among the various generalizations of these coefficients, we focus on the one that extends them to words over a finite alphabet A: given two ...

ABSTRACT This study examines climate change risk disclosure in the global energy sector, where firms face intense stakeholder scrutiny and legitimacy pressures. We develop a novel domain‐specific textual analysis measure to capture climate change risk disclosures, improving on prior approaches based on generic environmental terminology.

Option Implied Risk-Neutral Distributions and Implied Binomial Trees: A Literature Review [PDF]
In this selective literature review, we start by observing that in efficient markets, there is information incorporated in option prices that might help us to design option pricing models.
