The microlevel actions undertaken by owner-managers in improving the sustainability practices of cultural and creative small and medium enterprises: A United Kingdom–Italy comparison

Abstract: This article discusses microlevel actions undertaken by owner-managers, and how such actions affect stakeholders in enhancing the sustainability of small and medium enterprises (SMEs), the knowledge on which is lacking in the extant literature. The paper, by adopting an inductive analytical approach, draws key insights from the literature on microfoundations and sustainability and evidence from representatives of 5 Cultural and Creative Industry SMEs in Italy and of 5 in the United Kingdom. The findings suggest that owner-managers play a crucial role when engaging in sustainability activities jointly with employees and other stakeholders, through which individual-level actions enhance collective organizational-level sustainability practices. The U.K. and Italian cases highlight 2 contrasting approaches to dealing with sustainability; thus, the paper contributes to the emerging literature on SME microfoundations and sustainability.

Integrability of Hurwitz partition functions

Abstract: Partition functions often become ?-functions of integrable hierarchies, if they are considered dependent on infinite sets of parameters called time variables. The Hurwitz partition functions Z = ?Rd2 ? kR?R(t(1))??R(t(k))exp?(?n?nCR(n)) depend on two types of such time variables, t and ?. KP/Toda integrability in t requires that k ? 2 and also that CR(n) are selected in a rather special way, in particular the naive cut-and-join operators are not allowed for n > 2. Integrability in ? further restricts the choice of CR(n), forbidding, for example, the free cumulants. It also requires that k ? 1. The quasi-classical integrability (the WDVV equations) is naturally present in ? variables, but also requires a careful definition of the generating function.

Test–retest reliability of freesurfer measurements within and between sites: Effects of visual approval process

Abstract: In the last decade, many studies have used automated processes to analyze magnetic resonance imaging (MRI) data such as cortical thickness, which is one indicator of neuronal health. Due to the convenience of image processing software (e.g., FreeSurfer), standard practice is to rely on automated results without performing visual inspection of intermediate processing. In this work, structural MRIs of 40 healthy controls who were scanned twice were used to determine the test-retest reliability of FreeSurfer-derived cortical measures in four groups of subjects-those 25 that passed visual inspection (approved), those 15 that failed visual inspection (disapproved), a combined group, and a subset of 10 subjects (Travel) whose test and retest scans occurred at different sites. Test-retest correlation (TRC), intraclass correlation coefficient (ICC), and percent difference (PD) were used to measure the reliability in the Destrieux and Desikan-Killiany (DK) atlases. In the approved subjects, reliability of cortical thickness/surface area/volume (DK atlas only) were: TRC (0.82/0.88/0.88), ICC (0.81/0.87/0.88), PD (0.86/1.19/1.39), which represent a significant improvement over these measures when disapproved subjects are included. Travel subjects' results show that cortical thickness reliability is more sensitive to site differences than the cortical surface area and volume. To determine the effect of visual inspection on sample size required for studies of MRI-derived cortical thickness, the number of subjects required to show group differences was calculated. Significant differences observed across imaging sites, between visually approved/disapproved subjects, and across regions with different sizes suggest that these measures should be used with caution.
