Household food insecurity positively associated with increased hospital charges for infants

Objective: To test whether household food insecurity (HFI) was associated with total annual hospitalization charges, annual days hospitalized, and charges per day, among low-income infants (months) with any non-neonatal hospital stays. Methods: Administrative inpatient hospital charge data were matched to survey data from infants\u27 caregivers interviewed 1998-2005 in emergency departments in Boston and Little Rock. All study infants had been hospitalized at least once since birth; infants whose diagnoses were not plausibly related to nutrition were excluded from both groups. Log-transformed hospitalization charges were analyzed, controlling for site fixed effects. Results: 24% of infants from food-insecure households and 16% from food-secure households were hospitalized \u3e2 times (P=0.02). Mean annual inpatient hospital charges ($6,707 vs$5,735; P Conclusion: HFI was positively associated with annual inpatient charges among hospitalized low income infants. Average annual inpatient charges were almost $2,000 higher (inflation adjusted) for infants living in food-insecure households. Reducing or eliminating food insecurity could reduce health services utilization and expenditures for infants in low-income families, most of whom are covered by public health insurance

Identifying Advantages and Disadvantages of Variable Rate Irrigation – An Updated Review

Variable rate irrigation (VRI) sprinklers on mechanical move irrigation systems (center pivot or lateral move) have been commercially available since 2004. Although the number of VRI, zone or individual sprinkler, systems adopted to date is lower than expected there is a continued interest to harness this technology, especially when climate variability, regulatory nutrient management, water conservation policies, and declining water for agriculture compound the challenges involved for irrigated crop production. This article reviews the potential advantages and potential disadvantages of VRI technology for moving sprinklers, provides updated examples on such aspects, suggests a protocol for designing and implementing VRI technology and reports on the recent advancements. The advantages of VRI technology are demonstrated in the areas of agronomic improvement, greater economic returns, environmental protection and risk management, while the main drawbacks to VRI technology include the complexity to successfully implement the technology and the lack of evidence that it assures better performance in net profit or water savings. Although advances have been made in VRI technologies, its penetration into the market will continue to depend on tangible and perceived benefits by producers

Microscope Mode Secondary Ion Mass Spectrometry Imaging with a Timepix Detector

In-vacuum active pixel detectors enable high sensitivity, highly parallel time- and space-resolved detection of ions from complex surfaces. For the first time, a Timepix detector assembly was combined with a Secondary Ion Mass Spectrometer for microscope mode SIMS imaging. Time resolved images from various benchmark samples demonstrate the imaging capabilities of the detector system. The main advantages of the active pixel detector are the higher signal-to-noise ratio and parallel acquisition of arrival time and position. Microscope mode SIMS imaging of biomolecules is demonstrated from tissue sections with the Timepix detector

Scaffolding Learning for Teachers of Multilingual Learners Through Agency, Leadership, and Collaboration

Grounded in findings from multiple disciplines (e.g., neuroscience, human, development, cognitive science, and social psychology), Lee, Meltzoff, and Kuhl (2020) propose a framework to understand human learning. Composed of multiple propositions, one aspect of this framework emphasizes the social nature of learning. Specifically, they argue, “A comprehensive theory of human development must take into account basic motivations for learning from, through, and in relationship with social others” [emphasis added] (p. 25). Education researchers and practitioners working with multilingual students and their teachers have extensively argued for attention to “learning from, through, and in relationships with social others” (Lee et al., 2020, p. 25) (e.g. Hawkins, 2019; Viesca & Teemant, 2019). In fact, Viesca and Teemant (2019) describe how this should occur through attention to three assumptions from sociocultural theory (Vygotsky, 1978): (1) learning is social, (2) teaching is assistance and situated performance, and (3) knowledge is cultural and competent participation. These perspectives on learning are often taken into account when designing learning opportunities for students in K-12 classrooms and we argue they should for teacher professional learning as well. Further, our work and the study described here suggest that such learning for teachers is best accomplished through teacher agency, leadership, and collaboration

Long-term within-speaker consistency of filled pauses in native and non-native speech

Filled pauses are widely considered as a relatively consistent feature of an individual’s speech. However, acoustic consistency has only been observed within single-session recordings. By comparing filled pauses in two recordings made >2.5 years apart, this study investigates within-speaker consistency of the vowels in the filled pauses uh and um, in both first language (L1) Dutch and second language (L2) English, produced by student speakers who are known to converge in other speech features. Results show that despite minor within-speaker differences between languages, the spectral characteristics of filled pauses in L1 and L2 remained stable over time.NWO276-75-010Theoretical and Experimental Linguistic
