Psychological and Sociocultural Influences of Current and Historical Intimate Partner Violence in Pregnancy

The Centers for Disease Control and Prevention (CDC) estimates that 1.5 million women are victims of intimate partner violence (IPV) each year, and 324,000 of these women are pregnant (2013). Research on the predictability of certain factors and their relationship to current and historical IPV is limited. In order to better understand IPV as it related to a sample of 1,016 Appalachian pregnant women selected for the Tennessee Interventions for Pregnant Smokers (TIPS), it was important to evaluate various influences that may predict the prevalence of IPV in this population when compared to the State of Tennessee and the U.S. (Aim 1). An evaluation of psychological, sociocultural, and socioeconomic variables as they relate to both current and historical IPV in pregnant women presenting for prenatal care was conducted (Aim 2), and the results from this evaluation were used to model significant IPV influences to determine pregnancy predictors in the study sample when historical and current IPV is present (Aim 3). Percent prevalence of self-reported IPV was higher in the TIPS sample for Carter, Greene, Hawkins, Johnson, Sullivan, Washington, and Unicoi counties, when compared to criminal reports for State of Tennessee IPV victimization rates, and the rate per 1,000 IPV victimization rate was also higher in the TIPS sample when compared to the criminal report for the U.S. Self-esteem, social, support, stress, substance abuse, and alcohol were positive as independent effects for predicting IPV via ordinal regression; however, when evaluated via multinomial logical regression with controls for age, race, income, education, marital status, whether or not a pregnancy was planned, and parity, this effect was no longer noted. Unplanned pregnancies and lower education were significant control variables in these evaluations. The lack of support for predictive ability of those selected psychological and sociocultural variables for IPV only underscores the importance of taking into consideration the uniqueness of various populations and across various regions such as Appalachia. The influences of unplanned pregnancy and lower education may be significant predictors if IPV in pregnant women in Appalachia and warrant further research

Rescuing Inclusive Legal Positivism from the Charge of Inconsistency

Scott Shapiro, an exclusive legal positivist, argues that inclusive legal positivism is inconsistent with the view that legal norms must conceptually provide reasons for agents of a legal system to act in specified ways. I defend inclusive legal positivism from Shapiro\u27s charge of inconsistency

The Nature of Governmental Authority

This dissertation puts forward a series of arguments and theoretical proposals concerning institutional authority—particularly, governmental authority. I attend to conceptual debates regarding the function of legal systems and the nature of authority. Moreover, I cover a normative debate regarding the permissible use of political power. The overall view that I build is that governmental institutions have a decision-making authority over the status of certain normative relations in society, and they were designed to have this decision-making authority to serve the need of making group decisions, despite persistent disagreements about policy outcomes, in order to solve practical problems. Chapter 1, “My Overall Perspective,” provides a guide to my overall view regarding the nature of governmental authority. This PhD dissertation takes the form of the three-paper model, and a reader may not see the conceptual links between these papers. In this chapter, I present the view on the nature of governmental authority that comes out of these papers. Chapter 2, “The Presumption of Liberty and the Coerciveness of the State,” presents a challenge to skeptics who think that nearly all uses of political power is impermissible. I argue that a state can engage in permissible uses of political power over a broad range of domains without possessing any entitlements. Chapter 3, “What Authority Is, What It Is Not,” argues against the orthodoxy that authority is a species of power over others. I then build and defend the view that authority is a status that authorizes a person or entity to change one’s normative status. Chapter 4, “Law’s Function as a Decision-Procedure” provides an analysis of how we can determine the law’s essential function. I use this analysis to argue that the law’s essential function is a decision-making one. Each of these chapters is a standalone paper. None of these papers presupposes another one, and they can be read in any order

Impacts from ice-nucleating bacteria on deep convection: implications for the biosphere-atmosphere interaction in climate change

International audienceA cloud modeling framework is described to simulate ice nucleation by biogenic aerosol particles, as represented by airborne ice-nucleation active (INA) bacteria. It includes the empirical parameterization of heterogeneous ice nucleation. The formation of cloud liquid by soluble material coated on such insoluble aerosols is represented and determines their partial removal from deep convective clouds by accretion onto precipitation. Preliminary simulations are performed for a case of deep convection over Oklahoma. If present at high enough concentrations, as might occur in proximity to land sources, INA bacteria are found to influence significantly: – (1) the average numbers and sizes of crystals in the clouds; (2) the horizontal cloud coverage in the free troposphere; and (3) precipitation and incident solar insolation at the surface, which influence rates of bacterial growth. At lower concentrations, the corresponding responses of cloud fields appear much lower or are ambiguous. In nature, the growth rates of INA bacteria on leaves prior to emission into the atmosphere are known to be highly dependent on temperature, precipitation and plant species. Consequently, the open question emerges of whether emissions of such ice-nucleating biogenic particles can then be modified by their own effects on clouds and atmospheric conditions, forming a weak feedback in climate or microclimate systems

Role resources and work-family enrichment: The role of work engagement

The majority of work-family research has focused on negative spillover between demands and outcomes and between the work and family domains (e.g., work-family conflict; see review by Eby, Casper, Lockwood, Bordeaux, & Brinley, 2005). The theory that guided this research was in most cases role stress theory (Greenhaus & Beutell, 1985) or the role scarcity hypothesis (Edwards & Rothbard, 2000). However, according to spillover theory, work-related activities and satisfaction also affect non-work performance, and vice versa. Recently, in line with the positive psychology movement (Seligman & Csikszentmihalyi, 2000), work-family interaction research has also included concepts of positive spillover (Bakker & Schaufeli, 2008; Grzywacz & Marks, 2000). This emerging focus supplements the dominant conflict perspective by identifying new ways of cultivating human resource strength

Lineshape Asymmetry for joint CPT and three photon N resonances

We show that a characteristic two photon lineshape asymmetry arises in coherent population trapping (CPT) and three photon (N) resonances because both resonances are simultaneously induced by modulation sidebands in the interrogating laser light. The N resonance is a three-photon resonance in which a two-photon Raman excitation is combined with a resonant optical pumping field. This joint CPT and N resonance can be the dominant source of lineshape distortion, with direct relevance for the operation of miniaturized atomic frequency standards. We present the results of both an experimental study and theoretical treatment of the asymmetry of the joint CPT and N resonance under conditions typical to the operation of an N resonance clock.Comment: Accepted for publication in Optics Letters, 5 page

EEG alpha phenotypes: linkage analysis and relation to alcohol dependence in an American Indian community study

Abstract Background Evidence for a high degree of heritability of EEG alpha phenotypes has been demonstrated in twin and family studies in a number of populations. However, information on linkage of this phenotype to specific chromosome locations is still limited. This study's aims were to map loci linked to EEG alpha phenotypes and to determine if there was overlap with loci previously mapped for alcohol dependence in an American Indian community at high risk for substance dependence. Methods Each participant gave a blood sample and completed a structured diagnostic interview using the Semi Structured Assessment for the Genetics of Alcoholism. Bipolar EEGs were collected and spectral power determined in the alpha (7.5-12.0 Hz) frequency band for two composite scalp locations previously identified by principal components analyses (bilateral fronto-central and bilateral centro-parietal-occipital). Genotypes were determined for a panel of 791 micro-satellite polymorphisms in 410 members of multiplex families using SOLAR. Results Sixty percent of this study population had a lifetime diagnosis of alcohol dependence. Analyses of multipoint variance component LOD scores, for the EEG alpha power phenotype, revealed two loci that had a LOD score of 3.0 or above for the fronto-central scalp region on chromosomes 1 and 6. Additionally, 4 locations were identified with LOD scores above 2.0 on chromosomes 4, 11, 14, 16 for the fronto-central location and one on chromosome 2 for the centro-parietal-occipital location. Conclusion These results corroborate the importance of regions on chromosome 4 and 6 highlighted in prior segregation studies in this and other populations for alcohol dependence-related phenotypes, as well as other areas that overlap with other substance dependence phenotypes identified in previous linkage studies in other populations. These studies additionally support the construct that EEG alpha recorded from fronto-central scalp areas may represent an important endophenotype associated with alcohol and other substance dependence

EEG spectral phenotypes: Heritability and association with marijuana and alcohol dependence in an American Indian community study

Native Americans have some of the highest rates of marijuana and alcohol use and abuse, yet neurobiological measures associated with dependence on these substances in this population remain unknown. The present investigation evaluated the heritability of spectral characteristics of the electroencephalogram (EEG) and their correlation with marijuana and alcohol dependence in an American Indian community. Participants (n=626) were evaluated for marijuana (MJ) and alcohol (ALC) dependence, as well as other psychiatric disorders. EEGs were collected from six cortical sites and spectral power determined in five frequency bands (delta 1.0–4.0 Hz, theta 4.0–7.5 Hz, alpha 7.5–12.0 Hz, low beta 12.0–20.0 Hz and high beta/gamma 20–50 Hz). The estimated heritability (h2) of the EEG phenotypes was calculated using SOLAR, and ranged from 0.16 to 0.67. Stepwise linear regression was used to detect correlations between MJ and ALC dependence and the spectral characteristics of the EEG using a model that took into account: age, gender, Native American Heritage (NAH) and a lifetime diagnosis of antisocial personality and/or conduct disorder (ASPD/CD). Increases in spectral power in the delta frequency range, were significantly correlated with gender (p<0.001) and marijuana dependence (p<0.003). Gender, age, NAH and ASPD/CD were all significantly (p<0.001) correlated with theta, alpha and beta band power, whereas alcohol dependence (p<0.01), gender (p<0.001), and ASPD/CD (p<0.001) were all correlated with high beta/gamma band power. These data suggest that the traits of EEG delta and high beta /gamma activity are correlated with MJ dependence and alcohol dependence, respectively, in this community sample of Native Americans
