Understanding Age Differences in the Effects of Group Exercise Messaging
Full text linkMotivating people of different ages to exercise is an important step toward ensuring as much of the population reaches the recommended physical activity guidelines for the protection of everyone’s health. Generally, younger and older adults are differentially motivated due to shifts in goals, such that younger adults are focused on preparatory goals for the future and older adults on emotionally meaningful goals in the current moment (Carstensen, 2021). It should then follow that younger and older adults have different preferences for exercise. Understanding these differences is important for effectively designing exercise programs to target messages to various groups across the life span. Following the predictions of socioemotional selectivity theory (Carstensen, 2006, 2021), these studies were designed to provide an understanding of how differences in goals of younger and older adults might impact their affective and evaluative responses to different group-based exercise programs. To do so, we measured younger and older adults’ reactions to statements about different group-based exercise programs (i.e., how they felt about the programs, how effective the statements were, and how likely they would be to join those programs). Younger and older adults did not differ when rating socially-motivated exercise programs. However, the most individual-motivated exercise programs were more appealing for younger than older adults. These results were modified by both self-efficacy and physical activity level, such that older adults with low self-efficacy and low in physical activity were less likely to respond positively to nearly any program than younger adults low in these measures, but this was not the case for older and younger adults high in self-efficacy and physical activity levels. Age differences in this domain have relevant implications for messaging which aims to target different age groups and could help to inform the design of group exercise programs

Generative Artificial Intelligence in Hospitality and Tourism Marketing: Exploring Perceptions, Risks, and Benefits from a Managerial Standpoint
Full text linkThe rapid adoption of Generative Artificial Intelligence (GAI) is transforming hospitality and tourism marketing, offering both opportunities and challenges for industry professionals. This study explores the integration of GAI in the U.S. hospitality sector, focusing on its ethical, operational, and strategic implications. A mixed-methods approach was used, combining qualitative insights from 20 industry professionals with quantitative data from 163 participants. The findings reveal a dual perspective: while GAI enhances personalization, customer engagement, and operational efficiency, concerns remain regarding data privacy, customer trust, and ethical considerations. Despite these challenges, the high level of familiarity with GAI among participants suggests its growing adoption across the industry. The study highlights the importance of ethical AI implementation, advocating for industry-wide policies that address legal, social, and regulatory challenges. The practical implications provide a framework for hospitality businesses to integrate GAI responsibly while maintaining consumer trust and competitive advantage. The theoretical contributions expand the understanding of AI’s evolving role in hospitality marketing, bridging academic research with real-world industry needs. This report serves as a strategic guide for hospitality executives, policymakers, and marketers, ensuring that AI-driven innovation aligns with ethical standards and enhances industry sustainability
Exact Sampling of the Six-Vertex Model Using Coupling from the Past
Full text linkThis paper aims to explore the six-vertex model through simulations designed to investigate the behavior of configurations under specific domain wall boundary conditions. To generate random configurations, we employ the Markov Chain Monte Carlo method while addressing the challenge of mixing times by utilizing the Coupling from the Past (CFTP) algorithm. Implemented in Python, our approach leverages CFTP to ensure exact sampling, avoiding the uncertainty of convergence in traditional Monte Carlo methods. We explore the monotonicity property within this framework and prove that it is only maintained by the steps of this algorithm for very particular values of the parameters
Frustrated, but Motivated: Insights from People with ME/CFS
Full text linkQualitative research can amplify and clarify the perspectives of people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The current study analyzed responses to an open-ended survey question regarding the experiences of people with ME/CFS, especially in relation to ME/CFS case definitions. Although many people with ME/CFS are frustrated with their interactions with healthcare workers and researchers, people with this illness want these individuals to listen to them about their experiences with health care and research
Fireworks and Wood Combustion Impacts on Air Quality
Full text linkFire is used as a land management tool to improve ecosystem health and to reduce wildfire risk by lowering tree and litter density. However, prescribed fire as a management practice has faced difficulties with public perception, because of increased awareness of air pollution. Understanding the way that prescribed burns impact air quality and how beneficial they are for ecosystems can help the public to recognize their necessity. This study measured particulate matter (PM) emissions from prescribed burns but also considered other PM sources: fireworks and bonfires. The measurements were conducted in Minnesota, Wisconsin, and the Chicagoland area in the summer and fall of 2024. Low-cost instruments were used to measure particulate matter emissions and to evaluate air quality. The accuracy and use of these instruments were also considered in this study, particularly in relation to difficulties presented with freezing temperatures. While there were high Air Quality Index (AQI) values during the experiments, this study found that there were no long-term effects on air quality from any of the events. This underscores the fact that the negative smoke impacts from prescribed burns are far outweighed by the numerous benefits brought from prescribed burning

The Impact of the Co-Teaching Model on the Academic Growth of the General Education Student
No full textThis quantitative study aimed to determine whether there is a positive impact on the academic growth of general education students\u27 reading and math growth between co-taught classrooms compared to traditional one-teacher classrooms within a suburban public school district over the course of one academic year. The school district has implemented co-taught programming with longevity as a special education instructional model in three of the eight elementary schools and in both middle schools. This study focused on the conditional growth of standardized test scores in reading and math for fourth and fifth-graders who have not been identified with special education needs, compared to those taught by a traditional single general education teacher during one academic year across three elementary schools that provided both instructional models. This ex post facto quantitative study reviewed the NWEA MAP Conditional Growth Index (CGI) from Fall to Spring, comparing the growth of the students in the co-taught classroom against those in the traditional single-teacher classroom setting. It was assumed that general education students in the co-taught setting would demonstrate greater growth than their peers in a single-teacher setting due to the expertise of the special educator who modified instruction to benefit all learners, not only students who had identified special education needs. The study outcomes indicated statistically significant growth for general education students who received instruction in a co-taught setting, prompting a discussion about whether there is a need to expand this special education instructional model
The Civic Oath at Saint-Lazare, 1790
No full textThis study presents the French text, English translation, historical context, and a brief analysis of the speech given at Saint-Lazare on the civic oath-taking in support of the 1790 revolutionary government in France, which every adult citizen had to do publicly. At Saint-Lazare, a group of Vincentians and their neighbors assembled in the motherhouse’s chapel for the oath. This very rare and virtually unknown document is in Richardson Library’s special collections at DePaul University in Chicago. Oath-taking was a way of replacing royal legal authority before assemblies of citizens had been formed. By the time of this oath on 7 February 1790, Saint-Lazare had already been sacked out of the belief that it held grain supplies and ammunition. As one of the few remaining usable spaces there, the chapel may have held about 250 people consisting of three groups: the local Vincentian community, the soldiers stationed adjoining the Saint-Lazare property, and some local (male) citizens. The fifteen-minute speech was given by René-Pierre Devaudichon, the president of the local district. An image gallery of the pages of the original document follows the French text
