Deformations of colored sl(N) link homologies via foams

We generalize results of Lee, Gornik and Wu on the structure of deformed colored sl(N) link homologies to the case of non-generic deformations. To this end, we use foam technology to give a completely combinatorial construction of Wu's deformed colored sl(N) link homologies. By studying the underlying deformed higher representation theoretic structures and generalizing the Karoubi envelope approach of Bar-Natan and Morrison we explicitly compute the deformed invariants in terms of undeformed type A link homologies of lower rank and color.Comment: 64 pages, many figure

AI in space: Past, present, and possible futures

While artificial intelligence (AI) has become increasingly present in recent space applications, new missions being planned will require even more incorporation of AI techniques. In this paper, we survey some of the progress made to date in implementing such programs, some current directions and issues, and speculate about the future of AI in space scenarios. We also provide examples of how thinkers from the realm of science fiction have envisioned AI's role in various aspects of space exploration

Do Calories Count? Examining the Impact of Calorie Awareness on Food Selection

This study examined whether purchasing behavior of patrons in a college campus café changed when calorie information was provided. It compared weekly sales on food items before and after calorie information was posted for a group of target items (n = 6) that had calorie counts posted in fall 2017 and two groups of comparison items. Archival sales data were collected using the existing point-of-sale system. Sales of target items, which had calories displayed next to them, dropped significantly when compared with sales of the same items during the previous year. Sales of target items also dropped significantly when compared with sales of items matched either on food type or average sales in the year before posting calorie information. Findings indicate that posting calorie information had a significant effect on sales of items for which calorie information is displayed. Interestingly, most (80%) of the patrons of the café reported they were unaware of the calorie postings. Future research may focus on the impact of posting calorie information on the behavior of specific populations, settings, and formats. The addition of contextual information such as recommended daily caloric intake may provide additional perspective

Women in STEM: An Examination of Career Commitment as a Moderator to Organizational Commitment

Most research on women in STEM in the United States has revolved around retention, barriers, turnover intention, and underrepresentation in businesses, governments, and universities. This quantitative correlational study investigated whether career commitment moderated organizational commitment among women working in STEM careers based on independent variables of organizational justice and perceived organizational support. According to the U.S. Census Bureau (2020), in 2019, women made up 34% of the STEM workforce, or 12 million workers, and 52% of the non-STEM workforce, or 62 million workers. In 2006, President George W. Bush released the American Competitiveness Initiative for Science, Technology, Engineering, and Mathematics (STEM) Formal Education (Bush, 2006). In 2016, researchers advocated that STEM jobs in the United States are expected to increase to 1 million positions, 92% of which will require postsecondary education and training (Chen, 2013; Ellis et al., 2016; Olson & Riordan, 2012). The imbalance of women in STEM occupations reflects a lack of workforce diversity, which is valuable to organizations as it enriches innovation and organizational performance by representing differentiated backgrounds and experiences (Diaz-Garcia et al., 2013; Friedman et al., 2016; Herring, 2009; Hoever et al., 2012; Steele & Derven, 2015). Through the use of survey data from a sample of 111 working women in STEM careers in the United States, the hierarchical regression results were significant for two sub dimensions of organizational justice: interpersonal justice was significant (β = .331, p \u3c .001) and informational justice (β = .290, p \u3c .05) when career commitment was added as a moderator. Perceived organizational support showed significance representing 57% of organizational commitment (R2 = .567, p \u3c .001). Recommendations for businesses include gathering similar survey data among STEM professionals to ascertain a more customized approach to relational skillsets among women in STEM. The findings of this study could also be applied to educational institutions seeking to survey and assess their STEM program curriculum and add further research on participants in STEM based on gender and long-term retention in STEM careers

China: An Expatriates Discovery Of Culture And Customs

The purpose of this research paper is to share and uncover the differences between American and Chinese culture and customs. These revelations illustrate the culture and customs of various Chinese provinces and how they differ from those of the United States. Moreover, an analysis of etiquettes, business practices, the concept of face, and teaching experiences are provided. In conclusion, this paper will touch upon the experiences of an expatriate while teaching at a renowned Chinese university. The viewpoints are based on experiences and observations only and, in no way, reflect the nature and culture of China as a whole. The findings of this paper will also help Americans, either traveling or teaching overseas, to prepare themselves, and will enable the reader to form his or her own perception and draw conclusions from an individual perspective
