Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…
2021
Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…
Identifying the Sales Patterns of Online Stores with Time Series Clustering
2018
Electronic commerce, especially in the business-to-consumer (B2C) context, has for years been a popular research topic in information systems (IS). However, the prior research on the topic has traditionally been dominated by the consumer focus instead of the business focus of online stores. For example, whereas various segmentations exist for online consumers based on their purchase behaviour, no such segmentations have been developed for online stores based on their sales patterns. In this study, our objective is to address this gap in prior research by identifying the most typical sales patterns of online stores operating in the B2C context. By using self-organising maps (SOM) to analyse …

Turystyczny przewodnik po Piekle Mikołaja Reja, czyli o międzyplanetarnych podróżach duszy ludzkiej
2020
The article deals with the complex issue of presenting the underworld in the Reja's Wizerunk. The author draws attention to the presence in the output of the old Polish poet of many visionary elements borrowed from the most varied traditions and religious systems. The popular pattern of searching for spiritual perfection, fixed in the archetype of the topographic movement of the hero (Latin: Homo viator) turns out to be particularly visible. It turns out that at the very foundations of this imaginative pattern there is an ancient doctrine or interplanetary wandering of the soul. Most of the work was focused on the description of XI songs of Reja’s WizerunV, where a description of hell appea…
Cluster visual field progression and its relationship with optic disc changes
2015
Purpose Glaucoma diagnosis and follow up of progression is often based on structural and functional assessments. This study aimed to assess clustered progression and evaluate its correlation with the corresponding disc changes (RA sectors) obtained from HRT examinations. Methods 51 eyes from OHT and glaucoma patients with a minimum of 5 reliable visual ᴀ밄eld tests (HFA II i 24-2) and HRT with a follow-up >4 years were analyzed retrospectively. Linear regression of clusters deᴀ밄ned by the Glaucoma Hemiᴀ밄eld Test (GHT) was performed based on the mean threshold in each cluster. Global and sectoral rates of change in RAs were assessed and correlated with functional clustered measures. Cluste…
H&E Multi-Laboratory Staining Variance Exploration with Machine Learning
2022
In diagnostic histopathology, hematoxylin and eosin (H&E) staining is a critical process that highlights salient histological features. Staining results vary between laboratories regardless of the histopathological task, although the method does not change. This variance can impair the accuracy of algorithms and histopathologists’ time-to-insight. Investigating this variance can help calibrate stain normalization tasks to reverse this negative potential. With machine learning, this study evaluated the staining variance between different laboratories on three tissue types. We received H&E-stained slides from 66 different laboratories. Each slide contained kidney, skin, and colon tissue sampl…
On the convergence of zero-point vibrational corrections to nuclear shieldings and shielding anisotropies towards the complete basis set limit in wat…
2016
The method and basis set dependence of zero-point vibrational corrections (ZPVCs) to nuclear magnetic resonance shielding constants and anisotropies has been investigated using water as a test system. A systematic comparison has been made using the Hartree–Fock, second-order Møller–Plesset perturbation theory (MP2), coupled cluster singles and doubles (CCSD), coupled cluster singles and doubles with perturbative triples corrections (CCSD(T)) and Kohn–Sham density functional theory with the B3LYP exchange-correlation functional methods in combination with the second-order vibrational perturbation theory (VPT2) approach for the vibrational corrections. As basis sets, the correlation consisten…
Work–Family Boundary Management Profiles in Two Finnish Samples : A Person-oriented Approach
2015
Background: The present study aims to identify different work-family boundary management profiles among Finnish employees, and examine how these relate to conflict between work and family or their mutual enrichment. Method: Participants from two samples, one consisting of university staff (n1 = 1,139) and another of nurses (n2 = 271), were asked to respond to an online survey concerning work-family boundary management, work-to-family enrichment, and work-to-family conflict scales. Results: A cluster analysis identified three profiles in both samples: segmentors, integrators and favoring family over work in the university sample, and segmentors, integrators and favoring work over family in t…
Relationship between trophic state and plankton community structure in 21 Sicilian dam reservoirs
1994
The relationship between the trophic state of 21 Sicilian dam reservoirs and their taxonomic community structure of phytoplankton (87 taxa) as well as zooplankton (45 taxa) have been examined by means of cluster analysis performed using annual average biomass values. The phytoplankton community structure was closely connected with the trophic state of the reservoirs, whereas the zooplankton community structure was related to hydrological regimes peculiar to the individual water bodies and not to the trophic state. © 1994 Kluwer Academic Publishers.
