Podcasting: A Beginner’s Guide to Technology’s Latest Trend

This article provides a starting place for teachers wanting to dabble with the latest trend in technology—podcasting. The authors present a general overview of a tool that will most likely be part of the teaching vernacular, if not now, in the very near future. We offer a short tutorial on podcasting as well as perspectives on how teachers might incorporate podcasts into their curricula. We also summarize the value and limitations of podcasts, and perhaps most importantly, we include a resource guide to some of the more intriguing and useful podcasts currently available

What May Be Associated with Young Adult E-Cigarette Use? Examination of Key Correlates

Given increasing rates of e-cigarette use among young adults, research is needed on the attitudes and beliefs that drive use among this age group. Tobacco control approaches used to prevent cigarette smoking may not work as effectively for preventing e-cigarette use. To address this research gap, the present study applied the Integrated Behavior Model (IBM) encompassing the affect heuristic theory to examine the individual-level determinants (i.e., attitude, perceived norm, personal agency, intention, and e-cigarette risk perception) of young adults\u27 e-cigarette use. The 2013-2014 Population Assessment of Tobacco and Health (PATH) Study Wave 1 baseline adult dataset consisted of 9,112 young adults (ages 18-24). A total of 3,887 (42.7%) reported ever having used an e-cigarette even one or two times, and reported now using e-cigarettes every day (n=160), some days (n=947), or not at all/non-users (2,780). Structural equation modeling (SEM) indicated that both the affect heuristic theory and constructs adapted from the IBM were significant drivers of e-cigarette use among young adults. The final structural model demonstrated acceptable fit (CFI = 0.935; TLI = 0.925; RMSEA = 0.024, 90% CI: 0.022-0.026). As expected for the IBM, as young adults’ positive feelings, perceived benefits, and normative beliefs of e-cigarettes increased, their intention to quit e-cigarettes decreased; which increased the likelihood of currently using e-cigarettes. As perceived benefit and positive feelings increased, young adults\u27 risk perceptions decreased resulting in a higher likelihood of using the device. These findings suggest that future communication, educational, and policy strategies to prevent e-cigarette use among young adults should highlight the health risk of e-cigarettes to address the high perceived benefits and low risk perceptions reported by young adults in this study

Dating Thach Lac: cryptic CaCO3 diagenesis in archaeological food shells and implications for C-14

In many locations around the world, shell radiocarbon dates underpin archaeological research. The dating of shell brings the chronological relationship between the sample and target event (e.g., hunting and food preparation) into congruence, while shells are valuable geochemical proxies for understanding past climate dynamics and environments. However, this information can be lost as the shell, composites of biopolymers and carbonate minerals (mostly calcite and or aragonite), undergo diagenetic alteration. While studies into Pleistocene-age carbonates are common in the radiocarbon literature, there has been little research into the impact of alteration on Holocene-age shells used to interpret recent societal developments. The limits of our understanding of these diagenetic changes became evident when dating Placuna placenta (naturally calcitic) and Tegillarca granosa (naturally aragonitic) shells from the site of Thach Lac in Vietnam. These shells returned ages significantly younger than associated charcoal and terrestrial bone at the site, but standard tests for secondary recrystallization (XRD and staining techniques) did not indicate any alteration. Further investigation revealed that cryptic recrystallization (i.e., of the same crystal structure) had occurred in both the calcite and aragonite shells. This finding suggests recrystallization may have an undetected impact on some shell radiocarbon dates

Exploring the role of OXTR gene methylation in attachment development: A longitudinal study

he current study explored longitudinally whether oxytocin receptor gene methyla-tion (OXTRm) changes moderated the association between parental sensitivity changesand children’s attachment changes over three waves. Six hundred six Flemish children(10–12 years, 42.8%–44.8% boys) completed attachment measures and provided sali-vary OXTRm data on seven CpG sites. Their parents reported their sensitive parenting.Results suggest that OXTRm changes hardly link to attachment (in)security changesafter the age of 10. Some support was found for interaction effects between parentalsensitivity changes and OXTRm changes on attachment changes over time. Effects sug-gest that for children with increased OXTRm in the promotor region and decreasedmethylation in the inhibitor region over time, increased parental sensitivity was asso-ciated with increased secure attachment and decreased insecure attachment overtime.info:eu-repo/semantics/acceptedVersio

Promoting students’ interest through culturally sensitive curricula in higher education

Previous studies have emphasized culturally sensitive curricula in the context of enhancing minoritized students’ education. We examined the relationship between second-year higher education students’ perceptions of the cultural sensitivity of their curriculum and both majoritized and minoritized students’ interest in their course. A total of 286 (228 F) students rated the cultural sensitivity of their curriculum on six scales using a revised version of the Culturally Sensitive Curricula Scales (CSCS-R), the perceived quality of their relationships with teachers, and their interest. The CSCS-R widened the construct with two new scales and showed better reliability. Ethnic minority students (n = 99) perceived their curriculum as less culturally sensitive than White students (n = 182), corroborating previous findings. Black students perceived their curriculum as less culturally sensitive than Asian students. There were no significant differences between ethnic minority and White students on interest or perceived quality of relationships with teachers. Five dimensions of cultural sensitivity (Diversity Represented, Positive Depictions, Challenge Power, Inclusive Classroom Interactions, Culturally Sensitive Assessments) and perceived quality of relationships with teachers predicted interest. Ethnicity did not. Ensuring curricula and assessments represent diversity positively, challenge power and are inclusive may support students’ interest while reflecting an increasingly diverse society

Finding Water Scarcity Amid Abundance Using Human–Natural System Models

Water scarcity afflicts societies worldwide. Anticipating water shortages is vital because of water’s indispensable role in social-ecological systems. But the challenge is daunting due to heterogeneity, feedbacks, and water’s spatial-temporal sequencing throughout such systems. Regional system models with sufficient detail can help address this challenge. In our study, a detailed coupled human–natural system model of one such region identifies how climate change and socioeconomic growth will alter the availability and use of water in coming decades. Results demonstrate how water scarcity varies greatly across small distances and brief time periods, even in basins where water may be relatively abundant overall. Some of these results were unexpected and may appear counterintuitive to some observers. Key determinants of water scarcity are found to be the cost of transporting and storing water, society’s institutions that circumscribe human choices, and the opportunity cost of water when alternative uses compete
