The company you keep: The influence of popular delinquents and deviant brokers on offending trajectories

open access: yesCriminology, EarlyView.
Abstract Research on how delinquent peer associations affect individuals’ life courses is limited. This paper addresses this gap by examining delinquent peer network characteristics and their impact on offending trajectories through social network analysis (SNA) and group‐based trajectory modeling (GBTM).

Tits alternatives for graph products

open access: yes, 2015
We discuss various types of Tits Alternative for subgroups of graph products of groups, and prove that, under some natural conditions, a graph product of groups satisfies a given form of Tits Alternative if and only if each vertex group satisfies this ...

Short‐Term Profits for Long‐Term Value: Corporate ESG Dilemmas Under Earnings Pressure and Pathways to Governance

open access: yesAccounting &Finance, EarlyView.
ABSTRACT This study examines the negative effect of earnings pressure (EP) on corporate environmental, social, and governance (ESG) performance and explores governance mechanisms that can address this problem. Drawing on behavioural agency theory and incorporating insights from resource allocation theory and agency theory, this paper identifies the key

Hereditary conjugacy separability of right angled Artin groups and its applications

open access: yes, 2012
We prove that finite index subgroups of right angled Artin groups are conjugacy separable. We then apply this result to establish various properties of other classes of groups.

The Role of Social Value in Data‐Intensive Health Research

open access: yesBioethics, EarlyView.
ABSTRACT Data‐intensive health research complicates traditional requirements for informed consent, due to the amount of data contributors and data points, the open‐ended nature of research questions, and repeated or secondary data use. To still enable data‐intensive health research, there is a move towards other—generally lower—standards for consent ...

Refining effect size measures and classification for differential item functioning: Toward unified guidelines across methods

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Differential Item Functioning (DIF) analysis is used to identify potentially biased items in multi‐item measurements. In addition to testing the statistical significance, it is essential to evaluate the practical significance of DIF through effect size measures.

On the number of prime order subgroups of finite groups [PDF]

open access: yes, 2009
Let G be a finite group and let ?(G) be the number of prime order subgroups of G. We determine the groups G with the property ?(G)??G?/2?1, extending earlier work of C. T. C.

Genetic Evolution in BRCA1‐Associated Breast Cancer Reveals Early Driver Mutations Shaping Tumor Features and Prognosis

open access: yesCancer Science, EarlyView.
Multi‐region sequencing of 57 BRCA1‐associated breast cancers identified TP53 as the dominant initial driver, defining a triple‐negative subgroup with biallelic BRCA1 loss and elevated genomic instability. TP53 truncating mutations were enriched in BRCA1 carriers and linked to reduced HRD, EMT activation, and a trend toward worse survival.

The operational effectiveness of a full capacity protocol to ease crowding at an emergency department

open access: yesDecision Sciences, EarlyView.
Abstract Using detailed timestamp data for patient visits and laboratory test orders from the emergency department (ED) of a large, urban, teaching hospital in the United States, we examine the operational effectiveness of the full capacity protocol (FCP), a set of temporary hospital‐wide guidelines that seek to alleviate crowding at the ED.
