Autonomous or controlled self-regulation, that is the question: A self-determination perspective on the impact of commuting on employees’ domain-specific functioning

The few studies that have considered psychological processes during the commute have drawn an ambiguous picture, with some emphasizing the negative and others the positive consequences of commuting. Drawing on self-determination theory, we develop a framework that expands on the costs and benefits of commuting for employees’ subsequent domain-related functioning at work and home. Specifically, we propose employees’ basic needs satisfaction and processes of autonomous and controlled self-regulation as mechanisms that explain how psychological commute characteristics spill over to domain-related functioning through experienced subjective vitality. In doing so, we introduce a taxonomy of psychological commute characteristics and highlight the importance of separating these underlying subjective characteristics from objective aspects of the commuting environment. Our research encourages scholars to conduct within- and between-person studies to examine how the objective commute environment and associated psychological commute characteristics affect employees’ self-regulation

National Set of Hydrogen Codes and Standards for the US

The US has a national set of codes and standards that address the use of hydrogen technologies. These documents are published by several organizations and are not all directly adopted by government authorities. The US Department of Energy (DOE) has acted as the central organizing group to identify these documents and present them as a coherent and integrated set of requirements

Should I Stay or Should I Go? The Role of Daily Presenteeism as an Adaptive Response to Perform at Work Despite Somatic Complaints for Employee Effectiveness

Our study seeks to contribute to scholarly understanding of the antecedents and consequences of the crucial, but so far overlooked within-person daily fluctuations in presenteeism. Drawing on theoretical frameworks of presenteeism, which conceptualize presenteeism as an adaptive behavior to deliver work performance despite limitations due to ill-health, we develop a within-person model of daily presenteeism and examine somatic complaints and work-goal progress as crucial joint determinants of daily fluctuations in presenteeism. We further integrate the aforementioned theoretical frameworks with ego-depletion theory to argue that presenteeism requires self-regulation to suppress cognitions, emotions, and behavioral responses associated with ill-health and instead focus on completing one’s work tasks. Accordingly, we predict that presenteeism depletes employees’ regulatory resources and impairs employees’ next-day work engagement and task performance. The results of a daily-diary study across 15 workdays with N = 995 daily observations nested in N = 126 employees show that daily work-goal progress attenuates the daily relation between somatic complaints and presenteeism, thereby also reducing the indirect effect of somatic complaints on employees’ next-day work engagement and task performance through presenteeism and ego depletion. We discuss the theoretical and practical implications of shifting presenteeism research from the macro- to the micro-level. (PsycInfo Database Record (c) 2023 APA, all rights reserved

Component-resolved Near-infrared Spectra of the (22) Kalliope System

We observed (22) Kalliope and its companion Linus with the integral-field spectrograph OSIRIS, which is coupled to the adaptive optics system at the W.M. Keck II telescope on March 25 2008. We present, for the first time, component-resolved spectra acquired simultaneously in each of the Zbb (1-1.18 um), Jbb (1.18-1.42 um), Hbb (1.47-1.80 um), and Kbb (1.97-2.38 um) bands. The spectra of the two bodies are remarkably similar and imply that both bodies were formed at the same time from the same material; such as via incomplete re-accretion after a major impact on the precursor body.Comment: 20 pages, 5 figures, 1 table.

Hirota's Solitons in the Affine and the Conformal Affine Toda Models

We use Hirota's method formulated as a recursive scheme to construct complete set of soliton solutions for the affine Toda field theory based on an arbitrary Lie algebra. Our solutions include a new class of solitons connected with two different type of degeneracies encountered in the Hirota's perturbation approach. We also derive an universal mass formula for all Hirota's solutions to the Affine Toda model valid for all underlying Lie groups. Embedding of the Affine Toda model in the Conformal Affine Toda model plays a crucial role in this analysis.Comment: 36 pages, LaTe

CARTIER: Cartographic lAnguage Reasoning Targeted at Instruction Execution for Robots

This work explores the capacity of large language models (LLMs) to address problems at the intersection of spatial planning and natural language interfaces for navigation.Our focus is on following relatively complex instructions that are more akin to natural conversation than traditional explicit procedural directives seen in robotics. Unlike most prior work, where navigation directives are provided as imperative commands (e.g., go to the fridge), we examine implicit directives within conversational interactions. We leverage the 3D simulator AI2Thor to create complex and repeatable scenarios at scale, and augment it by adding complex language queries for 40 object types. We demonstrate that a robot can better parse descriptive language queries than existing methods by using an LLM to interpret the user interaction in the context of a list of the objects in the scene

Stop and go, where is my flow? How and when daily aversive morning commutes are negatively related to employees’ motivational states and behavior at work

Despite convincing evidence about the general negative consequences of commuting for individuals and societies, our understanding of how aversive commutes are linked to employees’ effectiveness at work is limited. Drawing on theories of self-regulation and by extension a conservation of resources perspective, we develop a framework that explains how an aversive morning commute—a resource-depleting experience characterized by interruptions of automated travel behaviors—impairs employees’ immersion in uninterrupted work (i.e., flow), which in turn reduces employee effectiveness (i.e., work engagement, subjective performance, and OCB-I). We further delineate theoretical arguments for daily self-control demands as a boundary condition that amplifies this relation and propose the satisfaction of employees’ basic needs as protective factors. Two diary studies across 10 workdays each (Study 1: 53 employees, 411 day-level data points; Study 2: 91 employees, 719 day-level data points) support most of our hypotheses. Study 1 demonstrates that daily aversive morning commutes negatively affect employees’ daily work engagement through lower levels of flow experiences, but only on days with high impulse control demands. In addition, we find initial support that employees’ general autonomy and competence needs satisfaction attenuate this interaction. Study 2 rules out alternative mechanisms (negative affect and tension), demonstrates ego depletion as an additional mediator of the relation between aversive morning commutes and work effectiveness, and replicates the hypothesized three-way interaction for daily competence need satisfaction. We critically discuss the findings and reflect on corporate interventions, which may allow people to more easily flow to and at work

How we get along depends on how you make me feel: An episodic perspective on leader–follower emotional entrainment and daily interaction quality

Leader–follower relationships are a cornerstone of leadership research. Considering recent developments that point to emotions as key determinants of dyadic relationships, we shift the focus of this literature to the episodic interplay of leader emotional expressions and follower emotional reactions for the emergence of high-quality interactions. Specifically, we develop an emotional entrainment perspective stating that the trajectory of leader emotional expressions and corresponding follower emotional reactions over the course of a day gives rise to follower perceptions of their interaction quality with their leader. We glean additional insights by examining follower attachment styles as a moderator. Results of an experience sampling study (Nemployees = 72, Ndays = 479) demonstrate that emotional entrainment of high-activated emotions (joy and fear) predicts end-of-day interaction quality contingent on followers' (avoidant and anxious) attachment styles. Future avenues for research on the emergence of high-quality leader–follower relationships are discussed

Ultraviolet and visible photometry of asteroid (21) Lutetia using the Hubble Space Telescope

The asteroid (21) Lutetia is the target of a planned close encounter by the Rosetta spacecraft in July 2010. To prepare for that flyby, Lutetia has been extensively observed by a variety of astronomical facilities. We used the Hubble Space Telescope (HST) to determine the albedo of Lutetia over a wide wavelength range, extending from ~150 nm to ~700 nm. Using data from a variety of HST filters and a ground-based visible light spectrum, we employed synthetic photometry techniques to derive absolute fluxes for Lutetia. New results from ground-based measurements of Lutetia's size and shape were used to convert the absolute fluxes into albedos. We present our best model for the spectral energy distribution of Lutetia over the wavelength range 120-800 nm. There appears to be a steep drop in the albedo (by a factor of ~2) for wavelengths shorter than ~300 nm. Nevertheless, the far ultraviolet albedo of Lutetia (~10%) is considerably larger than that of typical C-chondrite material (~4%). The geometric albedo at 550 nm is 16.5 +/- 1%. Lutetia's reflectivity is not consistent with a metal-dominated surface at infrared or radar wavelengths, and its albedo at all wavelengths (UV-visibile-IR-radar) is larger than observed for typical primitive, chondritic material. We derive a relatively high FUV albedo of ~10%, a result that will be tested by observations with the Alice spectrograph during the Rosetta flyby of Lutetia in July 2010.Comment: 14 pages, 2 tables, 8 figure
