Software business process adaptive approach supporting organization architecture evolution
No full textSoftware maintenance and evolution play an important role in the software engineering field, especially when current software becomes more and more complex and powerful. As an entity to implement business processes and gain revenue, valuable software is composed of business logic and corresponding organization role interaction interfaces. With the enterprise development, the organization architecture also evolves, like expanding, cross department cooperation, and so on. However, existing software process adaptive approaches mainly focus on handling the change of the business (program) logic instead of organization structure. Therefore, we propose an adaptive software business process approach that supports organization architecture evolution and automatically migrates the run-time process instances to the latest version. First, a business process adaptation model is designed, which includes the organization layer, business process layer and event layer that connects the two. Based on the model, the organization changing impact and business process model modification are formalized. Besides, the business process adaptation approach is designed. According to the dependence between the organization architecture and the business process activities, the affected domain detection algorithms for three basic business process structures and the business process instance migration algorithm are developed. Finally, the feasibility and stability of the proposed system are comprehensively evaluated with the synthetic data sets
Alzheimer\u27s disease and related dementias diagnosis in the United States among U.S.-born and foreign-born White, Black, Hispanic, and Asian older adults
No full textTimely clinical diagnosis of Alzheimer’s disease and related dementias (ADRD) is important for resource allocation, mitigating safety concerns, and improving quality of life. While studies have examined ADRD diagnosis disparities by race/ethnicity, few include its intersection with nativity. Our aims were to (1) estimate the odds of diagnosed ADRD among US- and foreign-born racial/ethnic groups compared to US-born White older adults and (2) make comparisons by nativity within each racial/ethnic group. We linked 2000–2017 National Health Interview Survey (NHIS) and 2001–2018 Medical Expenditure Panel Survey (MEPS) data (65 + years; n = 38,033). Race/ethnicity and nativity were measured using NHIS data. Diagnosed ADRD was determined using ICD-9 (290/294/331/797) or ICD-10 (F01/F03/G30/G31) billing codes created from self-reports during MEPS household interviews. Bivariate and multivariable analyses were adjusted for covariates based on Anderson’s behavioral model of health services use. US-born Black (OR = 1.74; 95% CI = 1.48–2.05), Hispanic (OR = 1.62; 95% CI = 1.14–2.29), and foreign-born Hispanic (OR = 1.63; 95% CI = 1.24–2.15) older adults, but not foreign-born Black or Asian older adults, had higher odds of diagnosed ADRD compared to US-born White older adults after adjusting for age and sex. After additional adjustment for education, health insurance, usual source of care, and chronic conditions, only US-born Black older adults continued to show higher odds (OR = 1.54; 95% CI = 1.27–1.87) of diagnosed ADRD compared to US-born White older adults. There were no differences in ADRD diagnosis by nativity within each racial/ethnic group. Findings highlight the need for including nativity in studies comparing racial/ethnic groups to Whites to fully capture the ADRD burden among US-born Black older adults
The soul of teaching: Insights from 50 years of experience in management education
No full textThis interview with Dr. Joan V. Gallos, 2023 recipient of the David L. Bradford Outstanding Educator Award from the Management and Organizational Behavior Teaching Society (MOBTS), explores the four components of what Gallos considers the “soul of teaching”—insights she wished she had understood when she began her teaching career more than 50 years ago. Her four insights advise educators to: (1) work with what they’ve got—and own it!, (2) fail in the right way (think progress, not perfection), (3) dive into the magic at the heart of teaching and learning, and (4) relax and take your time: becoming the best educator you can be is a journey of never arriving. The interview is presented to encourage others to both find the soul of their teaching and guide their individual and collective discovery of the connection, authenticity, and magic at the heart of all teaching and learning
Quantifying the effects of carborundum rock surface smoothing for Schmidt hammer R-value metrics measured on glacial erratics in the North American Great Lakes region
No full textSchmidt hammer R-values, which reflect the degree of rock surface weathering, can be paired with independent rock surface exposure ages to produce Schmidt hammer exposure-age dating (SHD) calibration curves that are used to provide rapid estimations of exposure ages for undated rock surfaces. In this Letter, we lay the groundwork for later establishing a SHD calibration curve based on glacial erratics deposited by the Laurentide Ice Sheet in the North American Great Lakes region. First, we establish a reference R-value for a calibration boulder, which may be used to facilitate direct comparison of R-values collected by different individuals using mechanical N-type Schmidt hammers, specifically. We then assess how no, light or heavy use of a carborundum puck to smooth rock surfaces affects resulting R-value data. Lastly, we compare two different R-value metrics on the same rock surface: Rmean (n = 30) versus ΔR (Rmax − Rmin of five consecutive R-values on the same spot). In all assessments, Rmean is similar for erratic surfaces with no and light surface treatment, and both are significantly lower than Rmean of surfaces with heavy treatment. Thus, we advise against the use of heavy surface treatment in SHD applications. We observe no relationship between inferred erratic age and either Rmean or ΔR, which could arise from inferred ages of erratics being inaccurate, from inferred ages of erratics being too similar or from measuring too few erratics from each landform
Emulsion polymerization process: Effects of particle nucleation mechanism on properties of acrylic-styrene latex
No full textThe properties of acrylic-styrene latex (ASL) were investigated using two different nucleation methods by changing the sequence of addition of components, without changing the overall composition of the systems. In the first method, the semi-batch method was used and in the second method, the seeded semi-batch method was used and these were named ASL-1 and ASL-2, respectively. The latexes were characterized by dynamic light scattering, differential scanning calorimetry, tensiometer, gel permeation chromatography, viscometer, scanning electron microscopy, and transmission electron microscopy. The results showed that despite having the constant compositions, the two latexes have significant differences in different parameters studied. Sample ASL-1 showed higher zeta potential, glass transition temperature, surface tension, number average molecular weight and viscosity compared to sample ASL-2, but showed lower particle size. The two synthesized ASLs were also evaluated for their potential for pigment wetting and dispersion, as measured by the color development, by incorporation of three pigment pastes (red, green and blue). The study showed interesting findings that for each color pigment paste, ASL-1 produced deeper color tone than ASL-2. Also, color differences (L, a, b scale), contrast ratios, and gloss of ASL-1 and ASL-2 latexes-based pigment pastes were compared

An early history of newspaper agents
No full textNewspaper agents have often been relegated to a minor role in the pre-history of advertising firms in the United States—individuals working at promotions long before the more recognizable modern advertising agents emerged in the twentieth century. This study reexamines the history of newspaper agents in the nineteenth century to determine who these agents were and what their duties included. The study used primary sources to examine an array of references to newspaper agents and to craft profiles on agents from thirteen newspapers in the first half of the century. The results show a much broader array of duties and identities than existing histories generally acknowledge
Parental perceptions of community and professional attitudes toward autism
No full textThe purpose of this study was to examine parent perceptions of professional and community attitudes about autism through the lens of parenting their autistic children from birth through adulthood. Implications of this research may assist with future development and study of professional and community supports of individuals on the autism spectrum and their families. The study participants consisted of 51 parents who had an adult-aged child on the autism spectrum. One-on-one interviews were conducted with parents about their experiences raising a child with autism. Data were double-coded and analyzed using a qualitative, phenomenological approach to explore parents’ experiences with and perceptions of society members’ attitudes towards autism. Positive and negative themes were identified across parents’ perceptions of professionals and of community members. Themes regarding professional attitudes included cooperating with family requests, presuming competence of individuals with autism, complacency towards the needs of families and individuals with autism, and discrimination towards the individual with autism based on age or level of need. Themes regarding community member attitudes included valuing the strengths of individuals with autism, accommodating autistic differences, intolerance of autistic traits, and prejudice towards individuals with autism. Findings indicate that professional and community members presented with both positive and negative attitudes towards autism and individuals on the autism spectrum, with negative attitudes proving more prevalent in parent recollections. Results suggest a need for further research and related training to improve interactions with and support of individuals with autism and their families
Financial Autonomy and Happiness in College Students: Can They Coexist?
Get PDFPrior research and theory suggest that happiness is often associated with charitable expenses and feelings of autonomy. The present research examines how autonomy influences the happiness experiences of participants when spending money either charitably or on themselves. Participants completed the research online in an hour setting. Participants were asked to imagine situations where they have the ability to spend money freely, or where they first must seek advice or consult before making spending decisions. For half of each of these participants, they were directed to consider spending money on themselves, whereas the other participants were directed to consider spending money on others or on charities. Then all participants completed a series of scales that measured outcomes consistent with happiness, autonomy, and feelings of financial restraint. It was hypothesized that spending money freely on others will result in higher happiness and autonomy ratings, as compared to people asked to spend money on themselves, as well as people asked to spend money on others when they first need to consult with others (e.g., non-autonomous). It was also hypothesized that feelings of financial restraint may moderate these effects, such that less happiness is experienced when individuals sense they do not have autonomy to spend freely. Although the results of the study did not support these hypotheses, it was found that the method used tended to increase happiness for college students who spent money on themselves freely compared to spending money on themselves after consulting how to spend. The results also demonstrated that the methods used seemed to make students feel more guilty about how they spend their money, particularly after thinking about spending money charitably. These results are interpreted in light of justification theories rather than studies that have induced happiness via charitable behaviors
