Second Grade Students Learn about Civil Engineers and Erosion

The integration of art into curricula focused on teaching science is a new perspective in education designed to reach a broader range of students. The current study examined the process of second-grade students participating in science and art activities through qualitative content analysis. The subjects of science and art were not taught to the students separately, rather, students engaged in both subjects simultaneously, in an integrated manner. Participants were 23 second-grade students (11 female and 12 male; age range 7 to 8 years) who were learning about erosion through sketching and creative construction and the work of civil engineers through role-play and exploration of problems they solve. Sources of information for the study included student-reported symbolism for engineering badges, classroom discussions, students’ responses during testing of sand hills, teacher observations, and student writings. Major themes in the process of the students were: connections to prior knowledge of erosion and engineers along with symbols connected to engineers; observing erosion and shapes of the land; integration of art bringing motivation; social learning and teamwork; problem-solving solutions to erosion; making connections between the classroom testing and the real world; and the desire to continue exploring erosion. The lessons emphasized learning through and with the arts, making the lessons engaging and motivating students to continue learning on their own

Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET

Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are considered to be more rigid in structure. Crystallization is often easier compared to proteins from bacteria growing at ambient temperatures, especially for membrane proteins. The ATP-producing enzyme FoF1-ATP synthase from thermoalkaliphilic Caldalkalibacillus thermarum strain TA2.A1 is driven by a Fo motor consisting of a ring of 13 c-subunits. We applied a single-molecule F\"orster resonance energy transfer (FRET) approach using duty cycle-optimized alternating laser excitation (DCO-ALEX) to monitor the expected 13-stepped rotary Fo motor at work. New FRET transition histograms were developed to identify the smaller step sizes compared to the 10-stepped Fo motor of the Escherichia coli enzyme. Dwell time analysis revealed the temperature and the LDAO dependence of the Fo motor activity on the single molecule level. Back-and-forth stepping of the Fo motor occurs fast indicating a high flexibility in the membrane part of this thermophilic enzyme.Comment: 14 pages, 7 figure

Dirty laundry: The nature and substance of seeking relationship help from strangers online

Interpersonal relationships are vital to our well-being. In recent years, it has become increasingly common to seek relationship help through anonymous online platforms. Accordingly, we conducted a large-scale analysis of real-world relationship help-seeking to create a descriptive overview of the nature and substance of online relationship help-seeking. By analyzing the demographic characteristics and language of relationship help-seekers on Reddit (N = 184,631), we establish the first-ever big data analysis of relationship help-seeking and relationship problems in situ among the general population. Our analyses highlight real-world relationship struggles found in the general population, extending beyond past work that is typically limited to counseling/intervention settings. We find that relationship problem estimates from our sample are closer to those found in the general population, providing a more generalized insight into the distribution and prevalence of relationship problems as compared with past work. Further, we find several meaningful associations between relationship help-seeking behavior, gender, and attachment. Notably, numerous gender differences in help-seeking and romantic attachment emerged. Our findings suggest that, contrary to more traditional contexts, men are more likely to seek help with their relationships online, are more expressive of their emotions (e.g., discussing the topic of "heartache"), and show language patterns generally consistent with more secure attachment. Our analyses highlight pathways for further exploration, providing even deeper insights into the timing, lifecycle, and moderating factors that influence who, what, why, and how people seek help for their interpersonal relationships

Formation of Cu and Ni Nanowires by Electrodeposition

In this work, the formation of Cu and Ni nanowires by electrodeposition inside alumina templates was analyzed. The depositswere performed from CuSO4 + H2SO4 and NiSO4 + NiCl2 + H3BO3 + H2SO4 solutions for the electrodeposition of Cu and Ni,respectively. To allow the cations deposition, sufficiently negative potentials were used. The experience time was rangedbetween 500s and 1h. After the metal electrodeposition, the sample was immersed in NaOH to dissolve the alumina membraneand to expose the generated deposit. The obtained nanostructures were characterized by SEM (scanning electron microscopy).Deposits were corresponded with nanowires having an average diameter of 300 nm. The length of the nanostructures was about10 microns.Fil: Meier, Lorena Alejandra. Universidad Nacional del Sur. Departamento de Ingeniería Química.

Second harmonic generation from plasmonic hotspots by controlled local symmetry breaking

Bonding resonant modes of plasmonic nanoantennas with narrow gaps exhibit very large local field enhancement. These hotspots are highly attractive for boosting optical nonlinearities, such as second harmonic generation. However, for resonant symmetric gap antennas, the strong second harmonic sources created at the gap interfaces oscillate out-of-phase and therefore interfere destructively in the far-field. Here, we use an advanced nanofabrication approach to systematically break the local symmetry of nanoscopic antenna gaps while retaining the bonding resonant antenna mode at the fundamental frequency and the concomitant intensity hotspot. We find that antennas with the strongest local symmetry breaking emit correspondingly intense second harmonic radiation as compared to symmetric reference structures. By combining these findings with second harmonic radiation patterns as well as quantitative nonlinear simulations, we obtain remarkably detailed insights into the mechanism of second harmonic generation at the nanoscale. Our findings open new perspectives for the realization of non-reciprocal nanoscale systems, where local symmetry breaking is crucial to create unique functionalities

An Exploratory Model of Shared Decision-Making in Women\u27s Reproductive Health in Indiana: A Cross-Sectional Study

Ecological approaches to shared decision-making (SDM) are underexplored in women’s reproductive health. The purpose was to identify ecological factors important to women in contraceptive and prenatal care SDM. In this cross-sectional study, women (18-45 years) living in Indiana who had sought reproductive healthcare completed an online survey (N=432). Multiple linear regression was utilized to identify predictors of SDM. Furthermore, exploratory factor analysis, confirmatory factor analysis, and structural equation modeling were conducted to explore ecological factors associated with SDM in contraception and prenatal care. Healthcare professional type was associated with decreased contraceptive SDM scores, but not prenatal care SDM scores. Access, social support, and patient-healthcare professional relationship demonstrated good global fit in confirmatory factor analysis. Path coefficients suggested significant relationships between these ecological factors and contraceptive and prenatal care SDM scores. Additionally, the ecological factors demonstrated good global fit for contraceptive and prenatal care SDM. Social support had a significant, strong, and inverse relationship with both contraceptive and prenatal care SDM in the models. Findings further SDM work by moving beyond option discussion and toward increased attention to women’s contexts and relationships. Taking a holistic approach to SDM and the patient experience ensures that women’s multi-faceted needs, influences, and preferences are met across healthcare settings
