Since the early 20th century, students across the United States have been learning sexual education in public classrooms. Although American society has made many advancements and social changes since then, the curriculum of sexual education has remained stagnant. It continues to stress the concept of “social hygiene,” promoting white, heterosexual norms while demoralizing adolescent sexuality (McCarty-Caplan 2013). Since the 1980’s, the federal government has created three federally funded programs to promote abstinence-only sexual education. Although there are no federal laws or policies that dictate states or districts must provide sexual education, the programs have pressured the boards and districts to teach what the federal government is promoting. Most importantly, these ideologies are being pushed on to the government by the Religious Right. This study examines the attitudes towards sexual education and the attitudes towards topics that are associated with the curriculum. The findings imply that religion and political identification play the largest role in influencing these attitudes, which explains the current state of sexual education.

For the Texas Department of Transportation (TxDOT), accurately predicting durations for right-of-way (R/W) acquisition and utility adjustment on highway projects has been deemed as one of the most important capabilities that regional districts should possess. Because this need is so pressing, TxDOT has sought to establish an effective methodology for predicting the durations of these two pre-construction processes. The “Right-of-Way Acquisition and Utility Adjustment Process Duration Information (RUDI) tool” was developed, which is an Excel-based tool that takes into consideration user inputs regarding project circumstances such as schedule urgency and levels of uncertainty. In this study, the accuracy of RUDI and the key drivers that affect the durations of R/W acquisition and utility adjustment have been examined in order to assess RUDI’s effectiveness in implementation on projects, to identify critical needs for enhancing RUDI, and to understand how practitioners can better predict durations needed for R/W acquisition and utility adjustment. RUDI proved useful in predicting durations with better accuracy in spite of limited data availability. Specifically, RUDI provided practitioners with reasonable duration ranges that can be used in better forecasting the durations of utility adjustment. Moreover, the study revealed that practitioners with more than 13 years of experience and R/W acquisition specialization showed better performance in estimating durations for R/W acquisition. Accurately estimated durations for utility adjustment were mostly provided by practitioners working at districts located in urban or metropolitan areas in Texas. The drivers identified significantly influential in predicting durations for R/W acquisition by the practitioners include “TxDOT Project Type,” “District R/W Annual Budget,” “Dedication of Funds to the Project,” “Funding Limitations for the Project,” “Level of Political Pressure,” “Need for Residential Relocation,” “Level of Local Availability of Replacement Housing Facilities,” and “Likelihood of Title Curative Actions,” “Status of Environmental Clearance,” “Status of Right-of-Way Map,” “Frequency of Eminent Domain,” “Right-of-Way and Utility Scope,” and “Number of Parcels for Acquisition.” Likewise, for estimating utility adjustment durations, the drivers deemed highly influential and important by the practitioners include “Dedication of Funds to the Project (R/W and Construction),” “Funding Limitations for the Project,” “Have Subsurface Utility Engineering (SUE) Investigations been Performed,” “Adjustment is Reimbursable Utility or Non-Reimbursable Utility,” “Status of Environmental Clearance,” “Status of Right-of-Way Map,” “Right-of-Way and Utility Scope,” “Number of Utilities Located in Private Easement,” and “Responsiveness of Utility Companies to TxDOT Needs.” These drivers should be considered key data points in RUDI because they can provide users with more duration ranges that can be useful in forecasting actual durations of R/W acquisition and utility adjustment on highway projects. The study also revealed that further research is needed to maximize the benefits of the RUDI tool, although validating the study’s findings was restricted due to a lack of data. Additional studies for improving the RUDI tool should focus both on collecting more recent data and reconstructing the tool in terms of function and structure. / text

Electroencephalography is a medical diagnosis technique. It consists in measuring the biopotentials produced by the upper layers of the brain at various standardized places on the skull. Since the biopotentials produced by the upper parts of the brain have an amplitude of about one microvolt, the measurements performed by an EEG are exposed to many risks. Moreover, since the present tendency is measure those signals over periods of several hours, or even several days, human analysis of the recording becomes extremely long and difficult. The use of signal analysis techniques for the help of paroxysm detection with clinical interest within the electroencephalogram becomes therefore almost essential. However the performance of many automatic detection algorithms becomes significantly degraded by the presence of interference: the quality of the recordings is therefore fundamental. This thesis explores the benefits that electronics and signal processing could bring to electroencephalography, aiming at improving the signal quality and semi-automating the data processing. These two aspects are interdependent because the performance of any semi-automation of the data processing depends on the quality of the acquired signal. Special attention is focused on the interaction between these two goals and attaining the optimal hardware/software pair. This thesis offers an overview of the medical electroencephalographic acquisition chain and also of its possible improvements. The conclusions of this work may be extended to some other cases of biological signal amplification such as the electrocardiogram (ECG) and the electromyogram (EMG). Moreover, such a generalization would be easier, because their signals have a wider amplitude and are therefore more resistant toward interference.

This investigation explored the role of informational and psychological privacy in the health context by examining the relationship between type of relationship (physician versus acquaintance), type of observation (self-report versus observation), and communication strategies used to restore or preserve privacy (interaction control, dyadic strategies, expressions of negative arousal, blocking and avoidance, distancing, and confrontation). It was hypothesized and confirmed that individuals report exhibiting more behaviors to restore or preserve informational privacy in response to an informationally privacy-invasive question posed by an acquaintance than by a physician. The hypothesis that presentation of an informationally privacy invasive question by the physician causes patients to exhibit more communication strategies after the privacy invasive question than before, was unsupported. Finally, the hypothesis that individuals actually exhibit more privacy restoration behaviors than they report using in a similar situation with their physician was also unsupported. Patients reported using more communication strategies than they actually exhibited. One confound to the self reports was that videotaped participants reported the use of fewer direct privacy restoring communication strategies than non-videotaped.

In this paper I attempt to address an interpretive difficulty that surrounds Hegel's position in the history of jurisprudence. After a brief overview of Hegel's project, I outline the first two sections of the Outlines of the Philosophy of Right in order to support my argument that Hegel advocates a natural law theory of legal validity. I then show that confusions regarding Hegel's place in the history of jurisprudence arise from his view that the ethical evaluation of laws is limited (with some exceptions) to procedural laws that govern the enactment and recognition of laws in the administration of justice. I end by providing Hegel's distinctive argument for legal publicity, which he takes to be essential for the enactment and recognition of valid law.

The topic of this thesis is justice and asylum. The central argument in the thesis is that citizens of all states have a moral right that entitles them to asylum in certain circumstances of deprivation. The right to asylum can be understood as a general derivative right, and it is grounded in the more fundamental entitlement to basic needs. More specifically, I argue that all persons whose basic needs are insufficiently protected in their home states have the right to asylum when they cannot be assisted with other remedial instruments by the international community within a reasonable timeframe. By using the right to asylum as a normative evaluative standard, I also argue that the existing refugee protective institutions are morally unsatisfactory, and that a 'moral refugee regime' should be established to replace the current protective institutions. Then the questions becomes, what specific form these institutions should take. In the thesis I focus primarily on one institutional proposal, 'the tradable quota scheme', and its ethical dimensions. I defend the tradable quota scheme against several lines of criticism, and suggest that the scheme constitutes a normatively viable alternative for the existing institutional framework. Finally, I examine obligations in the protection of the right to asylum in circumstances of partial compliance. I conclude that the citizens of complying states have the obligation to 'pick up the slack' and assist those bearers of the right to asylum who are unjustly denied assistance by the non-complying states.

CHDS State/Local / The need for domestic intelligence and information sharing to detect indications and warnings of terrorist acts and prevent them has raised privacy and civil liberties concerns. The relationship between national security and privacy and civil liberties is often modeled as a scale with security on one end and privacy and civil liberties on the other. Success is said to be achieved when security and privacy are balanced. This model forces these values to be traded in a zero-sum game. A new model that decreases the "cost" to privacy and increases the "value" to security is needed. Technological, policy and organizational innovation hold promise in designing new intelligence and information-sharing architectures capable of detecting indications and warnings of terrorism and protecting the privacy and civil liberties of Americans. Using government documents that articulate attributes for a terrorism early warning system and widely accepted privacy principles as design requirements, the thesis examines technologies that could meet the challenges of both security and privacy. Designing and building a system that supports both security and privacy will benefit both. The thesis argues, this system will enable the Nation to fight terrorism while upholding the liberties that form the core values of the American people. / Captain (Capt), US Northern Command (Northcom) - NORAD J5
