Purpose The aim of this paper is to investigate the relationship between perceived social identity as an “older worker” and attitudes towards early retirement commitment work. Design/methodology/approach Survey data were obtained from 352 workers aged 50‐59. Hierarchical regression analyses performed test influence after controlling for demographics, organizational variables work‐to‐family conflict. Findings results show that self‐categorization related negative work (stronger desire retire...

Abstract Although many governments of the Organization for Economic Cooperation and Development are currently trying to retain older workers in workforce, numerous stereotypes question their motivation ability work, learn, develop. In two studies, we examined influence age-related stereotypic information on Belgian workers' aspirations work domain. Study 1, early retirement intentions were lower following exposure positive than negative or no information. 2, confronted with less willing...

Abstract Changes in canopy architecture traits have been shown to contribute yield increases. Optimizing both light interception and efficiency of agricultural crop canopies will be essential meeting the growing food needs. Canopy is inherently three‐dimensional (3D), but many approaches measuring component treat as a two‐dimensional (2D) structure make large scale measurement, selective breeding, gene identification logistically feasible. We develop high throughput voxel carving strategy...

Abstract This study investigated the role of intergroup processes in older workers' attitudes towards work and early exit from workplace. Specifically, relationships between four variables (cognitive affective identification with workers as a group, permeability retirees' group boundaries, younger boundaries) derived Social Identity Theory (Tajfel & Turner, Citation1979) (early intention, organizational commitment, psychological disengagement, competition workers) were examined using sample...

Selection for yield at high planting density has reshaped the leaf canopy of maize, improving photosynthetic productivity in settings. Further optimization architecture may be possible. However, measuring angles, widely studied component trait architecture, by hand is a labor and time intensive process. Here, we use multiple, calibrated, 2D images to reconstruct 3D geometry individual sorghum plants using voxel carving based algorithm. Automatic skeletonization segmentation these geometries...

Abstract Procedural modeling allows for an automatic generation of large amounts similar assets, but there is limited control over the generated output. We address this problem by introducing Automatic Differentiable Modeling (ADPM). The forward procedural model generates a final editable model. user modifies output interactively, and modifications are transferred back to as its parameters solving inverse problem. present auto‐differentiable representation that significantly accelerates...

We propose a semantic shape editing method to edit 3D triangle meshes using parametric implicit surface templates, benefiting from the many advantages offered by analytical representations, such as infinite resolution and boolean or blending operations. first template fitting optimize its parameters best capture input mesh. For subsequent edits, our novel mesh deformation allows tracking template's 0-set even when featuring anisotropic stretch and/or local volume change. make few assumptions...

Procedural modeling has produced amazing results, yet fundamental issues such as controllability and limited user guidance persist. We introduce a novel procedural model called PICO (Procedural Iterative Constrained Optimizer) PICO-Graph that is the underlying designed with optimization in mind. The key novelty of it enables exploration generative designs by combining both environmental constraints into single framework using without need to write rules. consists set geometry generating...

We introduce Dendry, a procedural function that generates dendritic patterns and is locally computable. The controlled by parameters such as the level of branching, degree local smoothing, random seeding disturbance parameters, range branching angles. It also global control defines overall shape can be used, for example, to initialize minima. algorithm returns distance tree structure which implicitly constructed on fly, while requiring small memory footprint. evaluation performed in parallel...

Abstract Differences in canopy architecture play a role determining both the light and water use efficiency. Canopy is determined by several component traits, including leaf length, width, number, angle, phyllotaxy. Phyllotaxy may be among most difficult of traits to measure accurately across large numbers individual plants. As result, simulations canopies grain crops such as maize sorghum, this trait frequently approximated alternating 180° angles between sequential leaves. We explore...

Abstract This paper introduces a novel deep neural model for segmenting and tracking the number of leaves in sorghum plants phenotyping facilities. Our algorithm inputs sequence images plant outputs segmented leaves. The key novelty our approach is training model. Manual annotations are tedious, we have developed procedural three‐dimensional (3D) that provides detailed geometry texture to generate photorealistic 3D models. overall shape leaf determined by its skeleton, it varies curvature,...

Procedural implicit surfaces are a popular representation for shape modeling. They provide simple framework complex geometric operations such as Booleans, blending and deformations. However, their editability remains challenging task: the definition of is purely implicit, direct manipulation cannot be performed. Thus, parameters model often exposed through abstract sliders, which have to nontrivially created by user understood others each individual modify. Further, these sliders needs set...
