This paper presents a method for selecting salient 2D views to describe 3D objects for the purpose of retrieval. The views are obtained by first identifying salient points via a learning approach that uses shape characteristics of the 3D points (Atmosukarto and Shapiro in International workshop on structural, syntactic, and statistical pattern recognition, 2008; Atmosukarto and Shapiro in ACM multimedia information retrieval, 2008). The salient views are selected by choosing views with multiple salient points on the silhouette of the object. Silhouette-based similarity measures from Chen et al. (Comput Graph Forum 22(3):223-232, 2003) are then used to calculate the similarity between two 3D objects. Retrieval experiments were performed on three datasets: the Heads dataset, the SHREC2008 dataset, and the Princeton dataset. Experimental results show that the retrieval results using the salient views are comparable to the existing light field descriptor method (Chen et al. in Comput Graph Forum 22(3):223-232, 2003), and our method achieves a 15-fold speedup in the feature extraction computation time.

Background: This study investigated the factor structure of the parenting sense of competence (PSoC), a measure of parenting self-efficacy, in a sample of parents recruited when their infants were under 2 months old. Due to the lack of longitudinal analysis of the PSoC's factor structure over time, the study sought to establish if the published two-factor structure was consistent over an 18-month period.
Methods: Data collected from 536 parents who had participated in a randomised controlled trial of universal proportionate parenting support, delivered in five sites in England, were subject to confirmatory factor analysis (CFA).

Background: Self-management support is widely considered a critical aspect of nursing. Still, many studies indicate that nurses frequently experience difficulties in daily practice.
Objective: To gain a deeper understanding of the factors perceived by nurses to impede or promote their support of patients' self-management within the dynamic environment of the in-patient hospital setting.

Background: Widespread antibiotic prescribing contributes to globally emerging antimicrobial resistance (AMR). Despite stewardship recommendations by the Infectious Diseases Society of America, there is a lack of literature identifying barriers and facilitators to antimicrobial stewardship programs (ASPs) in United States (U.S.

Salient emotional visual cues receive prioritized processing in human visual cortex. To what extent emotional facilitation relies on preattentional stimulus processing preceding semantic analysis remains controversial. Making use of steady-state visual evoke potentials frequency-tagged to meaningful complex emotional scenes and their scrambled versions, presented in a 4-Hz rapid serial visual presentation fashion, the current study tested temporal dynamics of semantic and emotional cue processing.

Excessive salt or sodium intake is strongly linked to increased blood pressure, which is a major risk factor for cardiovascular diseases. This study aimed to qualitatively explore the views of key stakeholders on salt intake reduction and barriers and facilitators to reducing salt intake in Malaysian schools. The stakeholders in this study were school administrators, food operators, and consumers.
