Predictors of authorised, unauthorised and persistent absence among secondary school pupils in Scotland

open access: yesBritish Educational Research Journal, EarlyView.
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

open access: yesJ. Integer Seq., 2013
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

open access: yes, 2009
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?

open access: yes, 1995
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

open access: yesBritish Educational Research Journal, EarlyView.
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]

open access: yes
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 ...

Global Energy Corporations and Climate Change: The Role of Formal and Informal Institutions in Shaping Climate Change Risk Disclosure

open access: yesBusiness Strategy and the Environment, EarlyView.
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.

From Eco‐Policy to Green Practice: Government Eco‐Initiatives, Managerial Attention and Frugal Green Innovation in Saudi Arabia

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Considering the need for environmental sustainability and fulfillment of the needs of customers at the bottom of the pyramid, this study integrates the attention‐based view of organizations and situational leadership theory to examine the impact of government eco‐initiatives on frugal green innovation through managerial attention toward the ...
