All the Lonely People: an Integrated Review and Research Agenda on Work and Loneliness

Decades of studies spanning multiple disciplines have provided insight into the critical role of loneliness in work contexts. In spite of this extensive research, a comprehensive review of loneliness and work remains absent. To address this gap, we conducted a multidisciplinary review of relevant theory and research and identified 213 articles reporting on 233 empirical studies from management, organizational psychology, sociology, medicine, and other domains to uncover why people feel lonely, how different features of work can contribute to feelings of loneliness, and the implications of employee loneliness for organizational settings. This enabled a critical examination of the distinct conceptualizations and operationalizations of loneliness that have been advanced and the theories underpinning this scholarship. We developed a comprehensive conceptual model that integrates cognitive discrepancy theory, the affect theory of social exchange, and evolutionary theory. This model elucidates the core antecedents, mediators, outcomes, moderators, and interventions forming the nomological network of work related loneliness, including cross-level influences within teams and among leaders. Our review also identifies a number of promising areas for future inquiry to improve our understanding and measurement of loneliness, the process of experiencing and managing loneliness in the workplace, and potential interventions to reduce it. Finally, we provide tangible guidance for organizations and practitioners on how to address and mitigate employee loneliness. Ultimately, our review underscores the complex nature of loneliness and work and establishes a foundation for advancing both scholarly discourse and organizational practices in this critical domain

Investigating Environmental Controls on Temperature Dynamics in an Urban Stream

Water temperature is a critical environmental variable influencing aquatic ecosystems. This study investigated the factors controlling stream temperature and thermal stratification in Rock Creek (RC) and Bethany Lake, an urbanized watershed featuring an in-line irrigation pond and buried wastewater infrastructure. Previous research suggested that subsurface water flow might drive temperature shifts in Rock Creek during summer periods when flow from Bethany Lake ceases. From 2023 to 2024, continuous temperature and stage monitoring, combined with statistical methods including principal component analysis and random forest regression, were used to evaluate seasonal temperature dynamics and their controlling factors. Results confirmed that seasonal reversals in temperature trends occurred within Rock Creek, though these may have been strongly influenced by monitoring techniques and thermal stratification. During summer periods, Bethany Lake did not flow into Rock Creek, and within Rock Creek above and below Bethany Lake there was negligible streamflow. Solar irradiance emerged as the most influential parameter for stream warming during these periods. Unexpectedly, lake elevation had a measurable influence on Upper RC stage, suggesting hydrologic interactions that are not yet fully understood. Piezometer data indicated that variability in subsurface water elevation was correlated with fluctuations in Bethany Lake elevation, but only within piezometers near the middle of the study reach. Despite this, there was no measurable fluctuation of stream temperature in relation to subsurface water elevation. This study underscores the importance of understanding interactions among anthropogenic modifications, hydrologic connectivity, and environmental controls on stream temperature. These findings have implications for urban stream restoration and management, particularly in mitigating thermal stress on aquatic species during low-flow summer periods. Furthermore, in these low-flow settings, commonly used hydrologic measurement techniques and instrumentation may lack precision to identify fine-scale processes and connections. Isotopic techniques (tracer or natural abundance studies) or other methods may need to be applied to have a more accurate understanding of surface-subsurface hydrologic exchange

An Effective Genetic Algorithm for Mixed Precision

The precision of floating-point numbers is a critical task in high-performance computing. Many scientific applications rely on floating-point arithmetic, but excessive precision can lead to unnecessary computational overhead. Reducing precision may introduce unacceptable errors. Addressing this trade-off is essential for optimizing performance while ensuring numerical accuracy. In this paper, we present a genetic algorithm-based approach for tuning the precision of floating-point computations. Our method leverages algorithmic differentiation and first-order Taylor series approximation to assess the impact of precision variations efficiently. We employ stochastic partitioning algorithms with multiple precision combinations that meet the error requirements. Moreover, we present a genetic heuristic algorithm to determine the maximum number of variables that can sustain precision alterations without compromising the desired error threshold. The proposed approach is evaluated across various benchmark programs, analyzing the effects of precision tuning under increasing error thresholds. Our findings reveal that, for a majority of these programs, reducing precision through partitioning leads to significant performance enhancements, with improvements of up to 15%

Urban Oregon Ash - Inventory and plan development in the face of Emerald ash borer

The invasive beetle, Emerald ash borer (EAB) was first detected in Oregon within an urban area of Washington County in 2022. The spread of this beetle has already begun to take its toll on its preferred host tree, ash (Fraxinus spp.). Though there are many species of ash throughout the urban area, Oregon only has one native ash tree, Oregon ash (F. latifiolia) which is highly associated with stream corridors and wetland habitats. Along our streams Oregon ash helps provide soil infiltration, streambank stabilization, stream shade, and other critical ecosystem services throughout private and public lands alike. As EAB spreads it will kill much, if not all Oregon ash trees, which can grow to be over 100-feet tall when fully mature. Dead and weakened trees can pose severe social, economic, and environmental risks and impacts posing challenges with nearby homes, roads, and other infrastructure. EAB impacts coupled with other urban stressors including higher temperatures, drought, and soil compaction make for a complex and challenging dilemma resulting in significant economic burden to individual residents and government entities. This presentation shares an Ash tree inventory and management plan development tool specifically for use in urban forested natural areas. These tools were created to help engage a variety of urban communities and municipalities for a proactive response to EAB, saving time and money. The sooner urban areas can complete an ash inventory, the sooner long-term management plans can be implemented, public health can be ensured, and economic savings can be realized

Online Crime Reporting: Procedural Justice and Victims’ Psychological Outcomes

Online crime reporting is a newly emerging reporting method that is gaining popularity among law enforcement agencies globally for its efficiency, yet, little is known about the potential impacts of these systems on victims. This study aims to determine whether or not online systems are delivering a procedurally just experience to property crime victims, and to what extent this may impact their psychological well-being. The study uses survey responses from victims (N=788) using the Portland Police Bureau’s online reporting system. Multiple regression analyses were conducted to identify significant relationships between a variety of procedural justice factors and control variables. Significant findings from the analyses support the idea that low levels of perceived procedural justice delivered via the online system are significantly correlated with elevated levels of psychological distress for victims. The results of this study emphasize the need for further research on procedural justice in technology-mediated communications between law enforcement and crime victims and a greater knowledge of how online reporting impacts victims’ psychological outcomes

Access to Arynes from Arenes via Net Dehydrogenation: Scope, Synthetic Applications and Mechanistic Analysis

Arynes undergo a wide range of chemical transformations making them versatile reactive intermediates for organic synthesis. Access to arynes has long been dominated by pre-functionalised reagents, e.g., the venerable o-trimethylsilylaryl triflates. However, a move toward developing methods to access arynes that are both mild and efficient has prompted research into aryl “onium” aryne precursors. Here, we leverage aryl “onium” species as in situ or isolated intermediates in a net dehydrogenation of simple arenes as a novel and efficient way to access arynes. We describe a unified strategy in which two different tactics are employed to access diversely substituted arynes from simple arenes. (1) We developed a one-pot method that converts simple arenes into aryl thianthrenium salts and uses them in situ to generate arynes. (2) We developed a two-step process to convert arenes into aryl(Mes)iodonium salts and ultimately trapped arynes to expand the scope of compatible arenes. The net transformations from arenes to trapped arynes are complete with 2–4 hours. Mechanistic analysis through competition experiments, deuterium kinetic isotope effects (DKIE) and Density Functional Theory (DFT) provide key comparisons of the two approaches described in this work and yield a user\u27s guide for selecting the appropriate “onium” leaving group based on the arene

Next Arrival and Destination Prediction via Spatiotemporal Embedding with Urban Geography and Human Mobility Data

With the development of transportation networks, countless trajectory data are accumulated, and understanding human mobility from traffic data could be helpful for smart cities, urban computing, and urban planning. Extracting valuable insights from traffic data, such as taxi trajectories, can significantly improve residents’ daily lives. There are many studies on spatiotemporal data mining. As we know, arrival prediction or regional function detection encompasses important tasks for traffic management and urban planning. However, trajectory data are often mutilated because of personal privacy and hardware limitations, i.e., we usually can only obtain partial trajectory information. In this paper, we develop an embedding method to predict the next arrival using the origin–destination (O-D) pair trajectory information and point of interest (POI) data. Moreover, the embedding information contains region latent features; thus, we also detect the regional function in this paper. Finally, we conduct a comprehensive experimental study on a real-world trajectory dataset. The experimental results demonstrate the benefit of predicting arrivals, and the embedding vectors can detect the regional function in a city

Understanding Anionic Hyperporphyrins: TDDFT Calculations on Peripherally Deprotonated \u3ci\u3eMeso\u3c/i\u3e-Tetrakis(4-Hydroxyphenyl)porphyrin.

Presented herein is a DFT/TDDFT study of -tetrakis(4-hydroxyphenyl)porphyrin (H[THPP]) and its Meso-deprotonated tetraanionic form; the latter was modeled as both a free tetraanion and with various counterions. Based on our calculations, the experimentally observed hyperporphyrin spectra are attributed to an admixture of phenol/phenoxide character into the a-type HOMO of tetraphenylporphyrin. The admixture results in an elevation of the orbital energy of the HOMO in relation to other frontier orbitals, which accounts for the observed spectral redshifts. The calculations underscore differences in the performance of different exchange-correlation functionals. Thus, while the popular hybrid functional B3LYP greatly exaggerates the redshift of the far-red hyperporphyrin band of -deprotonated H[THPP], the range-separated functional CAMY-B3LYP predicts a more moderate redshift. The latter, however, fails to reproduce experimentally observed absorptions in the 550-600 nm range, potentially underscoring the still imperfect modeling of anionic hyperporphyrins

Inciting Action by Analyzing Pachirat

The book Every Twelve Seconds: Industrialized Slaughter and the Politics of Sight by Timothy Pachirat explores “the politics of sight”, or the intentional invisibilizing or transparentizing of repugnant acts in order to encourage or limit them, through the case study of a beef slaughter house in Omaha, NE. While also utilizing the politics of sight, Pachirat hopes for great political and social change concerning the immoral acts that happen at meat plants through a radical act of transparency: a narrative ethnography. Writers with similar goals of great change in social and political issues can make use of Pachirat’s techniques, which this article explains and summarizes. His style of writing hopes not to just spread awareness but incite action. After analyzing Pachirat’s book, four helpful tips were gathered: 1) conveying an objective tone through storytelling can better persuade readers by presenting as unbiased; 2) evidence and writing structure can be most effective when the writer sticks to their strengths by reflexively drawing on their background; 3) writers need to assess the restrictions they are under and the audience they wish to reach when effectively inciting a population to action; and 4) transparency can incite great social and political change, but to maximize its effectiveness writers must work within larger discussions to practice storytelling which is thoughtfully done and context-specific to each cause. By understanding these techniques, writers can enter larger discussions of writing as activism, encourage dialogue of multiple political and social issues, and hopefully incite change through action

Guidelines for a Good Life: How Morality Tales Have Shaped Communities and Cultural Landscapes

Morality tales have played a crucial role in shaping moral and political structures throughout history. These stories, varying in format from plays, to books, to even musical albums, are easily accessible to readers. They use simple language and terms that can be understood between social classes and strata to teach people how to live a more “moral” life. This paper studies the socio-political effects of these morality tales through in-depth analyses of the Greek Aesop’s Fables, Confucius’ the Analects, the Indian Panchatantra, the medieval play Everyman, and a modern American musical album “Free to Be… You and Me.” The lessons within these tales not only reflect the ethical ideals of their respective time periods, but also how they have changed and adapted to fit modern day life. By examining their enduring relevance and influence, this paper demonstrates how morality tales have shaped both individual lives and communities throughout cultures and time periods.
