Perceptions of boundary ambiguity and parentification effects on family satisfaction, family support, and perceived stress in young adults of divorced families

Master of ScienceSchool of Family Studies and Human ServicesAmber VennumUsing a sample of 109 students at a Midwestern university with divorced or separated parents I explored a) how sibling order and young adults’ age at parental divorce or separation impacted their experience of boundary ambiguity, parentification, stress, and family satisfaction and support, b) whether parentification mediated the effects of boundary ambiguity on stress, family support and family satisfaction, and c) whether sibling order moderated the relationship between these variables. I found that the child’s age at parental divorce/separation was positively correlated with boundary ambiguity, and negatively correlated with parentification, stress, family satisfaction, and social support. First or only children reported higher rates of parentification, specifically taking on a spousal role with their parents than younger siblings. Further, in divorced/separated families boundary ambiguity was positively related to young adults’ stress and negatively related to their levels of family satisfaction and family support both directly and indirectly through parentification. However, sibling order was not found to moderate the relationships between boundary ambiguity, parentification, family support, family satisfaction, and stress. Implications for theory and intervention are discussed

United Kingdom newsprint media reporting on sexual health and blood-borne viruses in 2010

Background: Improving sexual health and blood-borne virus (BBV) outcomes continue to be of high priority within the United Kingdom (UK) and it is evident that the media can and do impact the public health agenda. This paper presents the first large-scale exploration of UK national newsprint media representations of sexual health and BBVs. Methods: Using keyword searches in electronic databases, 677 articles published during 2010 were identified from 12 national (UK-wide and Scottish) newspapers. Content analysis was used to identify manifest content and to examine the tone of articles. Results: Although there was a mixed picture overall in terms of tone, negatively toned articles, which focussed on failures or blame, were common, particularly within HIV/AIDS, hepatitis B and C, and other sexually transmissible infection coverage (41% were assessed as containing negative content; 46% had negative headlines). Differences were found by newspaper genre, with ‘serious’ newspaper articles appearing more positive and informative than ‘midmarket’ newspapers or ‘tabloids’. Across the sample, particular individuals, behaviours and risk groups were focussed on, not always accurately, and there was little mention of deprivation and inequalities (9%). A gender imbalance was evident, particularly within reproductive health articles (71% focussed on women; 23% on men), raising questions concerning gender stereotyping. Conclusions: There is a need to challenge the role that media messages have in the reinforcement of a negative culture around sexual health in the UK and for a strong collective advocacy voice to ensure that future media coverage is positively portrayed

Content Analysis of Drug Offenders\u27 Sketches on the Draw-an-Event Test for Risky Sexual Situations

Objectives: To evaluate the utility of the Draw-an-Event Test for risky sexual situations (DET-RS), a nonverbal memory-based assessment tool used for productions of spontaneous content associated with risky sex. Methods: Traditional holistic coding analysis of 298 drug offenders\u27 content productions. Results: Content analyses of DET-RS sketches provided increased understanding of substance use and other context preceding risky sexual situations with different types of sex partners. None of the sketches including drugs depleted condoms, only one of the sketches with alcohol included a condom, and only 2 sketches mentioned sexually transmitted diseases. Conclusions: The DET-RS is a useful research tool for generating nonverbal context-specific stimuli associated with risky sexual situations

Quality Control of Pre-1948 Cooperative Observer Network Data

A recent comprehensive effort to digitize U.S. daily temperature and precipitation data observed prior to 1948 has resulted in a major enhancement in the computer database of the records of the National Weather Service’s cooperative observer network. Previous digitization efforts had been selective, concentrating on state or regional areas. Special quality control procedures were applied to these data to enhance their value for climatological analysis. The procedures involved a two-step process. In the first step, each individual temperature and precipitation data value was evaluated against a set of objective screening criteria to flag outliers. These criteria included extreme limits and spatial comparisons with nearby stations. The following data were automatically flagged: 1) all precipitation values exceeding 254 mm (10 in.) and 2) all temperature values whose anomaly from the monthly mean for that station exceeded five standard deviations. Addi- tional values were flagged based on differences with nearby stations; in this case, metrics were used to rank outliers so that the limited resources were concentrated on those values most likely to be invalid. In the second step, each outlier was manually assessed by climatologists and assigned one of the four following flags: valid, plausible, questionable, or invalid. In excess of 22 400 values were manually assessed, of which about 48% were judged to be invalid. Although additional manual assessment of outliers might further improve the quality of the database, the procedures applied in this study appear to have been successful in identifying the most flagrant errors

Death and Communal Mass-Mourning: Vin Diesel and the Remembrance of Paul Walker

This article examines Vin Diesel’s use of his public Facebook Page to mourn the loss of his friend and co-actor Paul Walker in the period from 2013-2015. It discusses how Vin Diesel performed his grief and how his mourning process was communally reflected and repeated by both Vin Diesel and Walker fans, who used Vin Diesel’s page to share and verbalise their own feelings of loss in a both public and safe space. An analysis of Vin Diesel’s own status updates and 1800 comments reacting to three popular status updates related to the death of Paul Walk posted over the course of more than a year show that commentary was used to make condolences to both Vin Diesel and Walker’s familes and to affectively express the users’ immediate feelings, both verbally and through the use of emojis. However, over time, both the form and intensity of expression of both Vin Diesel and his followers changed, pointing to the need to further study celebrity mourning processes on social media over extended periods of time

Observations and Regional Climate Model Simulations of Heavy Precipitation Events and Seasonal Anomalies: A Comparison

A regional climate model simulation of the period of 1979–88 over the contiguous United States, driven by lateral boundary conditions from the National Centers for Environmental Prediction–National Center for Atmospheric Research reanalysis, was analyzed to assess the ability of the model to simulate heavy precipitation events and seasonal precipitation anomalies. Heavy events were defined by precipitation totals that exceed the threshold value for a specified return period and duration. The model magnitudes of the thresholds for 1-day heavy precipitation events were in good agreement with observed thresholds for much of the central United States. Model thresholds were greater than observed for the eastern and intermountain western portions of the region and were smaller than observed for the lower Mississippi River basin. For 7-day events, model thresholds were in good agreement with observed thresholds for the eastern United States and Great Plains, were less than observed for the most of the Mississippi River valley, and were greater than observed for the intermountain western region. The interannual variability in frequency of heavy events in the model simulation exhibited similar behavior to that of the observed variability in the South, Southwest, West, and North-Central study regions. The agreement was poorer for the Midwest and Northeast, although the magnitude of variability was similar for both model and observations. There was good agreement between the model and observational data in the seasonal distribution of extreme events for the West and North-Central study regions; in the Southwest, Midwest, and Northeast, there were general similarities but some differences in the details of the distributions. The most notable differences occurred for the southern Gulf Coast region, for which the model produced a summer peak that is not present in the observational data. There was not a very high correlation in the timing of individual heavy events between the model and observations, reflecting differences between model and observations in the speed and path of many of the synoptic-scale events triggering the precipitation

Did BP Atone for its Transgressions? Expanding Theory on 'Ethical Apology' in Crisis Communication

© 2016 John Wiley & Sons Ltd. Ethical communication during crisis response is often assessed by external perceptions of the organization's intentions, rather than an assessment of the organization's communicative behaviors. This can easily lead researchers to draw editorial conclusions about an organization's ethics in crisis response rather than accurately describing its communicative behaviors. The case of BP's 2010 oil spill in the Gulf of Mexico provides a prime example for the importance of accurately assessing the ethical content of an organization's crisis response because the ethics of BP's response have been discussed in news and academic sources; yet little direct examination of the ethical content in BP's response has occurred. The findings have implications for communication ethics, social media engagement, and crisis communication more generally

Quenching of porous silicon photoluminescence by deposition of metal adsorbates

Luminescent porous silicon is formed by anodization of silicon in HF acid in the dark and then under UV illumination. When illuminated with UV, samples exhibit a bright orange photoluminescence with a quantum efficiency of order a few percent. Porous silicon is characterized as a very complex network of interconnecting pores which range in size from 1 nm to 100 nm. It has a surface area of order 500 m\sp2/cm\sp3. The mechanism responsible for efficient luminescence of porous silicon is unknown, although there is a growing consensus that quantum confinement is necessary element to any successful explanation. We have attempted to increase understanding in porous silicon by a series of experiments in which luminescence is quenched. We have performed experiments in which the luminescence was quenched by immersion in metal ion solutions. In these experiments, we found that those ions solutions which caused quenching required a metal cation with a positive standard reduction potential. In this case, the metal ion was electrochemically deposited onto the surface of the porous silicon. Numerous Auger electron spectroscopy measurements indicate that the metal is present in the porous silicon at significant concentrations ($\sim$5-15%) for those samples in which the porous silicon was removed from solution as soon as the photoluminescence had been quenched as observed by eye. SEM measurements show no significant topographic differences between luminescent and quenched porous silicon samples. We have performed experiments in which metals were evaporated onto the surface of porous silicon. We have found for experiments involving evaporation of metal onto the surface of luminescent porous silicon that only copper metal evaporated onto p-type porous silicon has caused quenching of photoluminescence. Copper was evaporated onto p- and n-type porous silicon, but only copper evaporated onto p-type porous silicon caused quenching of the photoluminescence. Significant diffusion was noted only for copper evaporated onto p-type porous silicon; thus, the presence of copper in porous silicon appears sufficient to quench photoluminescence in porous silicon.U of I OnlyETDs are only available to UIUC Users without author permissio

The influence of volcanic stratospheric aerosols on interannual global climate variations

A qualitative physical mechanism has been proposed to explain the forcing of the El Nino/Southern Oscillation (ENSO) by low-latitude volcanic stratospheric aerosols (Handler 1989). This mechanism is based on the normal global annual cycle resulting from the normal annual cycle in the distribution of incoming solar radiation. The presence of a volcanic stratospheric aerosol, which backscatters incoming solar radiation, is hypothesized to trigger the ENSO through an amplification of the normal annual decrease in wind strength and corresponding increase in sea surface temperatures (SST) in the eastern tropical Pacific Ocean. The observational evidence for an association between the record of volcanic eruptions and SST and the Southern Oscillation Index (SOI, Tahiti SLP minus Darwin SLP) over the last 120 years is examined using superposed epoch analysis. Composites using as key dates low-latitude volcanic eruptions suggest that these eruptions are followed by statistically significantly warm sea surface temperatures at least at the 1% level, if not higher, with the greatest warming generally occurring in the first three seasons after the eruption. Satellite data on the distribution of recent volcanic aerosols suggests that an aerosol must only be present over the tropics (about 20\sp\circS to 20\sp\circN) to trigger an ENSO event. For the physical mechanism by which an ENSO event may be triggered by a volcanic stratospheric aerosol, these results and the results of recent computer modeling studies imply the need for a shift away from past emphasis on surface cooling and SLP anomalies and toward consideration of stratospheric warming and changes in energy storage and transport.U of I OnlyETDs are only available to UIUC Users without author permissio
