Abusive Romantic Relationships among Adolescent and Young Adult Mothers

The associations between intimate partner violence (IPV) and mental health among adolescents and young adults were compared in the current study. The connections among marriage status, Latino heritage and abusive experiences were also analyzed. 672 women including 282 adolescents between the ages of 14 and 19 and 390 young adults aged 20 or 21 participated in the study. Significant correlations were discovered between anxiety and depression symptoms among adolescents while anxiety and IPV, anxiety and depression, depression and IPV were all significantly correlated among young adults. In addition, IPV and marriage status as well as marriage status and Latina heritage were significantly correlated among young adults. No significant findings came from linear or logistic regressions conducted with the adolescent data but, among young adults, linear regressions with IPV as the dependent variable led to significant relationships between IPV and marital status. In addition, logistic regressions indicated significant links in the young adult data between IPV and depression and anxiety symptoms. IPV during adolescence may be a different phenomenon than adult IPV or mental health symptoms may be latent variables that are reported later in life. Prevention programs for adolescents as well as young adults are encouraged.

A comparison of the radiation tolerance characteristics of multijunction solar cells with series and voltage-matched configurations

The effect of series and voltage-matched configurations on the performance of multijunction solar cells in a radiation environment was investigated. It was found that the configuration of the multijunction solar cell can have a significant impact on its radiation tolerance characteristics

A comparison of the radiation tolerance characteristics of multijunction solar cells with series and voltage-matched configurations

The effect of series and voltage-matched configurations on the performance of multijunction solar cells in a radiation environment was investigated. It was found that the configuration of the multijunction solar cell can have a significant impact on its radiation tolerence characteristics

The effect of different module configurations on the radiation tolerance of multijunction solar cells

The effect of different module configurations on the performance of multijunction (MJ) solar cells in a radiation environment was investigated. Module configuration refers to the electrical circuit in which the subcells of the multijunction cell are wired. Experimental data for AlCaAs, GaAs, InGaAs, and silicon single-junction concentrator cells subjected to 1 MeV electron irradiation was used to calculate the expected performance of AlGaAs/InGaAs, AlGa/silicon, GaAs/InGaAs, and GaAs/silicon Mj concentrator cells. These calculations included independent, series, and voltage-matched configurations. The module configuration was found to have a significant impact on the radiation tolerance characteristic of the MJ cells

Postpartum Transitions in Adolescent Mothers\u27 Romantic and Maternal Relationships

Minority adolescent mothers (N = 375) were interviewed during the prepartum (or early postpartum) period and approximately 1 year later (N = 186) regarding their maternal and romantic relationships, depressive symptomatology, and negative life events. Over time, adolescents reported that male partners provided more support than did mothers and that partners\u27 support was equally important to mothers\u27 support. Further, while support from mothers decreased over time, strain increased. Results highlight the importance of considering relationship stability, At Time 2, partner support was negatively associated with depression only among adolescents who retained the same partner (17%). In addition, adolescents who sustained a romantic relationship disruption (38%) reported more negative life events than did those who had not. Implications for research, intervention, and policy are discussed

The Effect of Growth Promoting Implants on Feedlot Performance by Gelbvieh Bulls

The objective of this research was to determine the effect on feedlot performance of implanting various growth promotants in young bulls. Responses to these various implants by bulls were compared to a control group of bulls to determine the differences in feedlot performance. These comparisons provide information to help determine the most effective methods of bull feeding

Statistical Analysis of Nonlinearly Propagating Acoustic Noise in a Tube

Acoustic fields radiated from intense, turbulent sound sources such as military jets and rockets are not well understood. In addition to the inherent random nature of the field, the amplitudes of the acoustic vibration are great enough that nonlinear considerations are necessary for modeling. In order to better understand these complex fields, high-amplitude noise in a tube is measured and analyzed. The basics of nonlinear acoustics will be covered briefly in this talk. Additionally, some statistical tools that are useful in analyzing random systems, such as probability density functions and skewness, will be explained. The measured evolution of the skewness of the first time derivative of high-amplitude noise in a tube will be presented

The Value of Literacy Practices

The concepts of literacy events and practices have received considerable attention in educational research and policy. In comparison, the question of value, that is, ‘which literacy practices do people most value?’ has been neglected. With the current trend of cross-cultural adult literacy assessment, it is increasingly important to recognise locally valued literacy practices. In this paper we argue that measuring preferences and weighting of literacy practices provides an empirical and democratic basis for decisions in literacy assessment and curriculum development and could inform rapid educational adaptation to changes in the literacy environment. The paper examines the methodological basis for investigating literacy values and its potential to inform cross-cultural literacy assessments. The argument is illustrated with primary data from Mozambique. The correlation between individual values and respondents’ socio-economic and demographic characteristics is explored
