Effects of Parental Incarceration: A Grandparent\u27s Perspective
This qualitative study explored grandparents’ perceptions of parental incarceration effects on the grandchildren they are raising. Children of incarcerated individuals are directly affected by the high incarceration rate in the United States and often find themselves displaced from the people and environment they know. As one of the most common caregivers for children with incarcerated parents, grandparents offer a unique perspective on the effects that parental incarceration has on children. The study found that grandparents perceive that the effects of parental incarceration on children are diverse. Children represented in the study were negatively affected emotionally and behaviorally by parental incarceration, displacement, and associated traumas, yet placement with a grandparent during periods of parental incarceration had positive effects on child outcomes. Grandparents indicated a need for external support, more of a voice, and a more efficient process for kinship care. To be most effective, social workers who encounter children and grandparents affected by parental incarceration should take time to carefully understand the unique effects of parental incarceration on the child, being careful not to assume that a child has been impacted by parental incarceration in any way

The Accentual Phrase in Singapore English.
‘This is the peer-reviewed but unedited manuscript version of the following article: Chong, A. J. and J. Sneed German (2017). "The Accentual Phrase in Singapore English." Phonetica 74(2): 63-80.The final, published version is available at https://www.karger.com/?DOI=10.1159/000447429This paper reports on a speech production experiment that explores whether the accentual phrase (AP) represents an abstract level of prosodic phrasing in Singapore English. Specifically, it tests whether the right edge of the AP is associated with phrase-final lengthening, the degree of which can be distinguished from lengthening associated with the intonational phrase (IP). Target words were produced in matched sentence contexts in 3 phrasal positions: AP-medial (wordfinal), AP-final, and IP-final. As predicted, target words in AP-final position were longer than those in AP-medial position and shorter than those in IP-final position. Analysis of target duration and f0 together shows that AP boundaries are well discriminated from medial positions. Together, these results strongly support an AP level of phrasing for Singapore English and highlight its role in predicting timing variability
Monsoonal Circulation of the McMurdo Dry Valleys, Ross Sea Region, Antarctica: Signal from the Snow Chemistry
McMurdo Dry Valleys (MDV, Ross Sea region, Antarctica) precipitation exhibits extreme seasonality in ion concentration, 3-5 orders of magnitude between summer and winter precipitation. To identify aerosol sources and investigate causes for the observed amplitude in concentration variability, four snow pits were sampled along a coast-Polar Plateau transect across the MDV. The elevation of the sites ranges from 50 to 2400 m and the distance from the coast from 8 to 93 km. Average chemistry gradients along the transect indicate that most species have either a predominant marine or terrestrial source in the MDV. Empirical orthogonal function analysis on the snow-chemistry time series shows that at least 57% of aerosol deposition occurs concurrently. A conceptual climate model, based on meteorological observations, is used to explain the strong seasonality in the MDV. Our results suggest that radiative forcing of the ice-free valleys creates a surface low-pressure cell during summer which promotes air-mass flow from the Ross Sea. The associated precipitating air mass is relatively warm, humid and contains a high concentration of aerosols. During winter, the MDV are dominated by air masses draining off the East Antarctic ice sheet, that are characterized by cold, dry and low concentrations of aerosols. The strong differences between these two air-mass sources create in the MDV a polar version of the monsoonal flow, with humid, warm summers and dry, cold winters
A new room-temperature equation of state of Bi up to 260 GPa
At room temperature, bismuth undergoes several structural transitions with
increasing pressure before taking on a body-centered cubic (bcc) phase at
approximately 8 GPa. The bcc structure is stable to the highest measured
pressure and its simplicity, along with its high compressibility and atomic
number, make it an enticing choice as a pressure calibrant. We present three
data sets on the compression of bismuth in a diamond anvil cell in a neon
pressure medium, up to a maximum pressure of about 260 GPa. The use of a soft
pressure medium reduces deviatoric stress when compared to previous work. With
an expanded pressure range, higher point density, and a decreased uniaxial
stress component, we are able to provide more reliable equation of state (EOS)
parameters. We also conduct density functional theory (DFT)
electronic-structure calculations that confirm the stability of the bcc phase
at high pressure.Comment: 7 pages, 5 figures in main text; 7 pages, 2 figures in supplemen
Solar Forcing Recorded by Aerosol Concentrations in Coastal Antarctic Glacier Ice, McMurdo Dry Valleys
Ice-core chemistry data from Victoria Lower Glacier, Antarctica, suggest, at least for the last 50 years, a direct influence of solar activity variations on the McMurdo Dry Valleys (MDV) climate system via controls on air-mass input from two competing environments: the East Antarctic ice sheet and the Ross Sea. During periods of increased solar activity, when total solar irradiance is relatively high, the MDV climate system appears to be dominated by air masses originating from the Ross Sea, leading to higher aerosol deposition. During reduced solar activity, the Antarctic interior seems to be the dominant air-mass source, leading to lower aerosol concentration in the ice-core record. We propose that the sensitivity of the MDV to variations in solar irradiance is caused by strong albedo differences between the ice-free MDV and the ice sheet
The Health Education Research Experience (HERE) program metadata dataset
Undergraduate subject pools are prevalent across disciplines in the United States. The Health Education Research Experience (HERE) Program was the first known course-based subject pool entirely managed and conducted online for online students enrolled in an introductory health education/health promotion course. The program was conducted within five semesters from Spring 2012 through Summer 2013. The HERE Program encompassed 13 studies embedded in two sections of an undergraduate online course at the University of Florida. The studies were all related to course topics and current research topics in health education/promotion (as identified through the Healthy People 2020 Framework). The topics ranged from the relatively less sensitive health aspects of college life (i.e., technology use) to studies assessing more sensitive health topics (i.e., intimate partner violence and sexual assault). In alignment with a best practice in survey design, the HERE Program's survey instruments included one metadata item embedded in each survey to identify which devices students used to complete the surveys. Understanding which devices students used for survey completion has ramifications for survey designers and survey researchers. In contrast to the relative uniformity of pen and paper surveys and control of the survey completion environment, online surveys may not look identical across personal devices and may be completed in increasingly varied environments. All studies, study procedures and protocols, and metadata collection procedures were approved by the university's Institutional Review Board. The data presented here were extracted from each survey's data files and aggregated. The aggregated metadata are available through Mendeley Data in a.csv file for widespread access. Descriptive statistics are presented in tables. The data provided in this article will benefit researchers interested in survey methodology, questionnaire design, modes of survey collection, and survey metadata. The data are hosted in the following Mendeley Data repository: https://data.mendeley.com/datasets/ht9jmd3cdt/2
