Sibling Care in Pediatric Hospitals by Certified Child Life Specialists

Denman Undergraduate Research Forum Honorable MentionCertified Child Life Specialists (CCLS) assist pediatric patients to promote optimal coping during hospitalization. CCLS provide play, prepare children for medical procedures, and aid in the coping of patients and their families. Recently the field of child life has expanded to include care for siblings of patients, the hospitalization of a sibling is ranked as one of the top stress inducing events for a child. This research specifically aims to uncover the type of care provided to siblings in hospitals by CCLS. While current literature exists regarding sibling needs, there is little information regarding the existence of sibling programs and the interventions CCLS use to help siblings cope The purpose of this study is to ascertain the psychosocial needs of siblings through a review of current scholarly literature, ascertain the care provided to siblings by CCLS, and uncover gaps in care between what is deemed necessary in the literature and the care that presently takes place in hospitals. To address the latter, I created a survey to assess the current state of sibling programs and interventions used in U.S. and Canadian hospitals. The survey was sent to CCLS across the U.S. and Canada through the use of a national list-serv. The study concluded that there is a high prevalence of sibling programs in medical institutions throughout the United States and Canada. Of the programs represented in the present study, 64% have programs focused specifically on siblings. Focuses of these sibling programs are on education for the siblings as well as on emotional expression for the siblings. Both education and emotional expression were deemed as important by the literature. No real gaps in care for siblings were found. There were, however, areas that the literature deemed important, but were not commonly used by the respondents of the study, including the use of support groups and activities to help children cope with disruption in daily activities. It is the intention of this research that the findings will prompt CCLS nationally to examine their programs to determine how to better meet the needs of siblings to positively affect their experience, coping and emotions during a pediatric illness.College of Education and Human Ecology Undergraduate Research ScholarshipNo embargoAcademic Major: Human Development and Family Scienc

The Use of Human and Conspecific Gestures By Capuchin Monkeys to Solve an Object-Choice Task

Most primates live in highly complex social systems, and therefore have evolved similarly complex methods of communicating with each other. One type of communication is the use of manual gestures, which are only found in primates. No substantial evidence exists indicating that monkeys use communicative gestures in the wild. However, monkeys may demonstrate the ability to learn and/or use gestures in certain experimental paradigms since they¿ve been shown to use other visual cues such as gaze. The purpose of this study was to investigate if ten brown capuchin monkeys (Cebus apella) were able to use gestural cues from monkeys and a pointing cue from a human to obtain a hidden reward. They were then tested to determine if they could transfer this skill from monkeys to humans and from humans to monkeys. One group of monkeys was trained and tested using a conspecific as the cue giver, and was then tested with a human cue-giver. The second group of monkeys began training and testing with a human cue giver, and was then tested with a monkey cue giver. I found that two monkeys were able to use gestural cues from conspecifics (e.g., reaching) to obtain a hidden reward and then transfer this ability to a pointing cue from a human. Four monkeys learned to use the human pointing cue first, and then transferred this ability to use the gestural cues from conspecifics to obtain a hidden reward. However, the number of trials it took for each monkey to transfer the ability varied considerably. Some subjects spontaneously transferred in the minimum number of trials needed to reach my criteria for successfully obtaining hidden rewards (N = 40 trials), while others needed a large number of trials to do so (e.g. N = 190 trials). Two subjects did not perform successfully in any of the conditions in which they were tested. One subject successfully used the human pointing cue and a human pointing plus vocalization cue, but did not learn the conspecific cue. One subject learned to use the conspecific cue but not the human pointing cue. This was the first study to test if brown capuchin monkeys could use gestural cues from conspecifics to solve an object choice task. The study was also the first to test if capuchins could transfer this skill from monkeys to humans and from humans to monkeys. Results showed that capuchin monkeys were able to flexibly use communicative gestures when they were both unintentionally given by a conspecific and intentionally given by a human to indicate a source of food

Regulatory Fit as Input for Stop Rules

Three experiments show that the motivational effects of regulatory fit (consistency between regulatory state and strategic means) are context-dependent. With no explicit decision rule about when to stop (Experiment 1) or an explicit enjoyment stop rule (Experiments 2 and 3), participants exerted more effort on tasks when experiencing regulatory fit than when experiencing regulatory nonfit. With an explicit sufficiency stop rule (Experiments 2 and 3), participants exerted less effort when experiencing regulatory fit than when experiencing regulatory nonfit. The interactive effect of regulatory fit and stop rules can be explained by misattribution of rightness feelings from regulatory fit: the effect was eliminated by drawing participants’ attention to an earlier event as a source of rightness feelings (Experiments 1 and 3)

Quantifying the Impact of Public Perceptions on Vaccine Acceptance Using Behavioral Economics

This study was conducted to evaluate the impact of public perceptions of vaccine safety and efficacy on intent to seek COVID-19 vaccination using hypothetical vaccine acceptance scenarios. The behavioral economic methodology could be used to inform future public health vaccination campaigns designed to influence public perceptions and improve public acceptance of the vaccine. In June 2020, 534 respondents completed online validated behavioral economic procedures adapted to evaluate COVID-19 vaccine demand in relation to a hypothetical development process and efficacy. An exponential demand function was used to describe the proportion of participants accepting the vaccine at each efficacy. Linear mixed effect models evaluated development process and individual characteristic effects on minimum required vaccine efficacy required for vaccine acceptance. The rapid development process scenario increased the rate of decline in acceptance with reductions in efficacy. At 50% efficacy, 68.8% of respondents would seek the standard vaccine, and 58.8% would seek the rapid developed vaccine. Rapid vaccine development increased the minimum required efficacy for vaccine acceptance by over 9 percentage points, γ = 9.36, p < 0.001. Past-3-year flu vaccination, γ = −23.00, p < 0.001, and male respondents, γ = −4.98, p = 0.037, accepted lower efficacy. Respondents reporting greater conspiracy beliefs, γ = 0.39, p < 0.001, and political conservatism, γ = 0.32, p < 0.001, required higher efficacy. Male, γ = −4.43, p = 0.013, and more conservative, γ = −0.09, p = 0.039, respondents showed smaller changes in minimum required efficacy by development process. Information on the vaccine development process, vaccine efficacy, and individual differences impact the proportion of respondents reporting COVID-19 vaccination intentions. Behavioral economics provides an empirical method to estimate vaccine demand to target subpopulations resistant to vaccination

No exit: social reproduction in an era of rising income inequality

What explains the unexpected, uneven, but unquestionably pervasive trend towards re-­‐familialization in the rich OECD countries? The usual arguments about political responses to rising income inequality, unstable families, and unstable employment predicted that the state would increasingly shelter people against risk, producing greater individuation and de-­‐ rather than re-­‐familialization. By contrast, we argue three things. First, re-­‐familialization has replaced de-­‐familialization. Second, unequal access to housing drives a large part of re-­‐familialization. Rather than becoming more ‘anglo-­‐nordic,’ countries are becoming more ‘southern european’ in the way that younger cohorts access housing. Third, this inequality driven insecurity and unequal access is felt differently not only between generational cohorts but also within cohorts.acceptedVersio

The Association between sensation seeking and well-being among college-attending emerging adults

Sensation seeking is a known risk factor for unsafe and reckless behavior among college students, but its association with well-being is unknown. Given that exploration plays an important psychosocial role during the transition to adulthood, we examined the possibility that sensation seeking is also associated with psychological wellbeing. In a large multisite US college sample (N = 8,020), scores on the Arnett Inventory of Sensation Seeking were positively associated with risk behavior, psychological well-being, and eudaimonic well-being. When sensation seeking dimensions were examined separately, well-being was found to be associated with high novelty seeking but with low intensity seeking

Association of Long-Term Exposure to Fine Particulate Matter and Cardio-Metabolic Diseases in Low- and Middle-Income Countries: A Systematic Review.

: Background: Numerous epidemiological studies indicated high levels of particulate matter less than2.5 μm diameter (PM2.5) as a major cardiovascular risk factor. Most of the studies have been conducted in high-income countries (HICs), where average levels of PM2.5 are far less compared to low- and middle- income countries (LMICs), and their socio-economic profile, disease burden, and PM speciation/composition are very different. We systematically reviewed the association of long-term exposure to PM2.5 and cardio-metabolic diseases (CMDs) in LMICs. METHODS: Multiple databases were searched for English articles with date limits until March 2018. We included studies investigating the association of long-term exposure to PM2.5 (defined as an annual average/average measure for 3 more days of PM2.5 exposure) and CMDs, such as hospital admissions, prevalence, and deaths due to CMDs, conducted in LMICs as defined by World Bank. We excluded studies which employed exposure proxy measures, studies among specific occupational groups, and specific episodes of air pollution. RESULTS: A total of 5567 unique articles were identified, of which only 17 articles were included for final review, and these studies were from Brazil, Bulgaria, China, India, and Mexico. Outcome assessed were hypertension, type 2 diabetes mellitus and insulin resistance, and cardiovascular disease (CVD)-related emergency room visits/admissions, death, and mortality. Largely a positive association between exposure to PM2.5 and CMDs was found, and CVD mortality with effect estimates ranging from 0.24% to 6.11% increased per 10 μg/m3 in PM2.5. CVD-related hospitalizations and emergency room visits increased by 0.3% to 19.6%. Risk factors like hypertension had an odds ratio of 1.14, and type 2 diabetes mellitus had an odds ratio ranging from 1.14-1.32. Diversity of exposure assessment and health outcomes limited the ability to perform a meta-analysis. CONCLUSION: Limited evidence on the association of long-term exposure to PM2.5 and CMDs in the LMICs context warrants cohort studies to establish the association

Human chromosome 17 NotI linking clones and their use in long-range restriction mapping of the Miller-Dieker chromosome region (MDCR) in 17p13.3

A NotI linking library constructed from flow-sorted human chromosome 17 material was screened to aid in construction of a long-range restriction map of the Miller-Dieker chromosome region (MDCR) in 17p13.3. A total of 66 clones were mapped to one of eight regions of chromosome 17 using a somatic cell hybrid panel, and 44/66 (67%) of these clones crosshybridized to rodent DNA on Southern blots. Of these, 24 clones were tested and all mapped to mouse chromosome 11, the homolog of human chromosome 17. Four linking clones mapped to 17p13.3 and were used for pulsed-field gel electrophoresis studies along with six other anonymous probes previously mapped to this region. Clone L132 was found to be deleted in all Miller-Dieker patients tested (n = 15) and therefore lies within the critical region for this disorder. It detects two NotI fragments (180 and 320 kb), one of which (320 kb) was shared by YNZ22 and YNH37, two probes previously shown to be co-deleted in all patients with the Miller-Dieker syndrome (MDS). These results indicate that all MDS patients share a minimum deletion region of &gt;370 kb. Two other NotI clones, L53 and L125, mapped telomeric to the MDS critical region and share a 600-kb MluI fragment with each other and with YNZ22/YNH37. This provides a 930-kb MluI map that encompasses the distal boundary of the MDS critical region but does not include the proximal boundary. A total of over 2 Mbp is represented in the MluI fragments by probes in subband p13.3, a cytogenetic region estimated to be 3-4 Mbp.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28541/1/0000339.pd

Checkpoints are blind to replication restart and recombination intermediates that result in gross chromosomal rearrangements

Replication fork inactivation can be overcome by homologous recombination, but this can cause gross chromosomal rearrangements that subsequently missegregate at mitosis, driving further chromosome instability. It is unclear when the chromosome rearrangements are generated and whether individual replication problems or the resulting recombination intermediates delay the cell cycle. Here we have investigated checkpoint activation during HR-dependent replication restart using a site-specific replication fork-arrest system. Analysis during a single cell cycle shows that HR-dependent replication intermediates arise in S phase, shortly after replication arrest, and are resolved into acentric and dicentric chromosomes in G2. Despite this, cells progress into mitosis without delay. Neither the DNA damage nor the intra-S phase checkpoints are activated in the first cell cycle, demonstrating that these checkpoints are blind to replication and recombination intermediates as well as to rearranged chromosomes. The dicentrics form anaphase bridges that subsequently break, inducing checkpoint activation in the second cell cycle
