Opportunistic Lookahead Routing Procedure For Delay Tolerant Networks, Priyanka Rotti Jan 2012

Opportunistic Lookahead Routing Procedure For Delay Tolerant Networks, Priyanka Rotti

LSU Master's Theses

Delay Tolerant Networks are wireless networks that have sporadic network connectivity, thus rendering the existence of instantaneous end-to-end paths from a source to a destination difficult or impossible. Hence, in such networks, message delivery relies heavily on the store-and-forward paradigm to route messages. However, limited knowledge of the contact times between the nodes poses a big challenge to effective forwarding of messages. In this thesis, we discuss several aspects of routing in DTNs and present one algorithm and three variants for addressing the routing problem in DTNs: (i) the Look-ahead Protocol, in which the forwarding decision at each node to …

Advising Terrorism: Material Support, Safe Harbors, And Freedom Of Speech, Peter Margulies Jan 2012

Advising Terrorism: Material Support, Safe Harbors, And Freedom Of Speech, Peter Margulies

UC Law Journal

Ever since Brandenburg v. Ohio, departures from content neutrality under the First Amendment have received strict scrutiny. However, in Holder v. Humanitarian Law Project (“HLP”), the Supreme Court decided that the perils of content regulation were less pressing than was the need to curb the human capital of groups, such as Hamas, designated as foreign terrorist organizations (“DFTOs”). As a result, the Court upheld a statute that bars “material support” of terrorist organizations, ruling that the statute bars speech coordinated with DFTOs, including training in negotiation or the use of international law. Some commentators have labeled HLP as heralding a …

Role Of Herpes Simplex Type I Glycoproteins In Entry And Cell-Cell Fusion, Sona Chowdhury Jan 2012

Role Of Herpes Simplex Type I Glycoproteins In Entry And Cell-Cell Fusion, Sona Chowdhury

LSU Doctoral Dissertations

Herpes simplex virus type I (HSV-1) is a neurotropic virus that infects primarily mucocutaneous epithelial cells and nervous tissue. Membrane fusion is an important aspect of the HSV-1 lifecycle, that occurs during viral entry (virus-cell fusion), viral spread (cell-to-cell fusion), as well as, during virion morphogenesis (assembly and egress). These membrane fusion steps involve complex interactions between multiple viral glycoproteins and cellular receptors. HSV-1 glycoprotein B (gB) is necessary but not sufficient for membrane fusion events. Despite the fact, that the majority of known hypermorphic mutations which cause extensive virus-induced cell fusion occur within glycoprotein K (gK); yet the role …

Note – Playing Hot Potato In The Market: The Ninth Circuit’S Better Approach To Calculating Loss For Securities Fraud Sentencing, Erica Connolly Jan 2012

Note – Playing Hot Potato In The Market: The Ninth Circuit’S Better Approach To Calculating Loss For Securities Fraud Sentencing, Erica Connolly

UC Law Journal

In United States v. Berger, the Court of Appeals for the Ninth Circuit departed from the Second and Fifth Circuits regarding the standard required to determine loss for securities fraud under the Federal Sentencing Guidelines. Unlike its sister circuits, the Ninth Circuit held that the Supreme Court’s reasoning in Dura Pharmaceuticals, Inc. v. Broudo for loss causation in civil securities fraud actions did not apply to the criminal sentencing context. Instead, the Ninth Circuit endorsed price inflation, which was rejected in Dura Pharmaceuticals, as a method of determining loss under the Guidelines. This Note examines the circuits’ decisions in light …

Regional Effects Of Monetary Policy, Taehee Han Jan 2012

Regional Effects Of Monetary Policy, Taehee Han

LSU Doctoral Dissertations

A key element of this dissertation is the examination of the regional and state level effects of monetary policy. The first essay compares two broad approaches to identifying the monetary policy shocks that are used to estimate the regional effects of monetary policy. One approach that has been used in the previous literature assumes that monetary policymakers respond to shocks to regional personal income but do not respond directly to shocks to national income. A second general approach assumes that monetary policymakers respond to shocks to national income but do not respond directly to region-specific income shocks. This assumption is …

Copper-Cobalt Catalysts For Conversion Of Syngas To Ethanol And Higher Alcohols, Miranda Louise Smith Jan 2012

Copper-Cobalt Catalysts For Conversion Of Syngas To Ethanol And Higher Alcohols, Miranda Louise Smith

LSU Doctoral Dissertations

Higher alcohols produced by catalytic conversion of synthesis gas are potential octane enhancers for transportation fuels. Copper-cobalt catalysts have emerged as alternatives to the ethanol-selective, but expensive, rhodium-based ones. The reducibility of the catalyst and the CO adsorption mode are important factors in directing the selectivity of CO hydrogenation toward methanol, hydrocarbons, or higher alcohols. In this study, Cu/SiO2, Co/SiO2, and bimetallic CuCo/SiO2 catalysts, as well as their tin-promoted analogues, were synthesized and characterized by TPR, in situ XRD, in situ XANES, and in situ DRIFTS. Cobalt addition to Cu/SiO2 created an amorphous fraction of CuO that was more easily …

Examination Of The Relationship Between Specific Classes Of Social Skill Behaviors And Academic Competence On The Social Skills Improvement System Rating-Scales, Michael James Vance Jan 2012

Examination Of The Relationship Between Specific Classes Of Social Skill Behaviors And Academic Competence On The Social Skills Improvement System Rating-Scales, Michael James Vance

LSU Doctoral Dissertations

An individual’s social competencies and interpersonal relationships have been repeatedly linked to a number of behaviors not typically directly associated with social skills including depression (Hokanson & Rupert, 1991) and aggressive behavior (McColloch & Gilbert, 1991). In addition to these more social behaviors, social skills have also been shown to be predictive of both risk and protective factors related to academic functioning (Newcomb, Bukowski, & Pattee, 1993; Parker & Asher, 1987). The current study aims to add to the literature by examining the relationship between teacher, parent, and self-ratings of specific classes of social skill behaviors and teacher ratings of …

The Occurrence And Effectiveness Of Deinstitutionalization Of The Mentally Ill In The Pre-Antipsychotic Era, Joni Maria Lee Pow Jan 2012

The Occurrence And Effectiveness Of Deinstitutionalization Of The Mentally Ill In The Pre-Antipsychotic Era, Joni Maria Lee Pow

LSU Master's Theses

Deinstitutionalization, as it occurred after the introduction of antipsychotics in 1954 has received much attention. However, little has been done to examine the occurrence and nature of deinstitutionalization before 1954. This study uses US census data on discharge and readmission rates of US mental hospitals from 1935 to 1964 to examine deinstitutionalization during both periods. Data are analyzed using an interrupted time-series model. The model was used to test for statistical significance of trends before and after the advent of antipsychotics, and to test for an effect of antipsychotics on deinstitutionalization. Discharge rates significantly increased in the period before antipsychotics, …

Woman Scorned?: Resurrecting Infertile Women's Decision-Making Autonomy, Jody L. Madeira Jan 2012

Woman Scorned?: Resurrecting Infertile Women's Decision-Making Autonomy, Jody L. Madeira

Articles by Maurer Faculty

Legal scholarship portrays women as reproductive decision makers in conflicting ways. The distinctions between depictions of infertile women and women considering abortion are particularly striking. A woman seeking infertility treatment, even one who faces no legal obstacles, is often portrayed as so emotionally distraught and desperate that her ability to give informed consent is potentially compromised. Yet, the legal academy has roundly rejected similar stereotypes of pregnant women considering abortion, depicting them as confident and competent decision makers. This Article argues that legal scholars' use of a "desperate woman" stereotype denies women's ability to critically assess the health risks and …

Putting Family Back In Work-Family Conflict: The Moderating Effect Of Family Life Stage On The Work-Family Interface, Rachel C. Trout Jan 2012

Putting Family Back In Work-Family Conflict: The Moderating Effect Of Family Life Stage On The Work-Family Interface, Rachel C. Trout

LSU Master's Theses

In the present study, various gaps in the work-family literature were addressed by investigating the moderating influence of family life stage on work-family specific support from organizations, supervisors, and coworkers as it relates to work-family conflict. Family life stage was also proposed to moderate the relationships between work-family conflict and work-related outcomes (i.e., turnover intentions and work engagement). Additionally, work-family research has often been criticized for its propensity to sample across occupations in a single study, resulting in a need to study work-family conflict in specific careers. For this reason, elementary school teachers were the focus of this study, as …

Unit Assessments For High School Geometry, Damayanthi Srimathi Jegart Jan 2012

Unit Assessments For High School Geometry, Damayanthi Srimathi Jegart

LSU Master's Theses

Abstract Eight unit tests closely aligned with the Louisiana Comprehensive Curriculum for high school geometry were developed. Five of these were administered, each to the same 115 students spanning all ability and attainment levels in a magnet school in a semi-rural Louisiana district. The results were analyzed to determine the quality of the questions as well as to glean information about student-learning. The test scores were compared to the results of the state-administered end-of-course test for high-school geometry. The main findings were as follows: a) most students do not communicate their reasoning or justification unless directed to do so, and …

Proton Dose Calculations In Homogeneous Media, John Wesley Chapman, Jr. Jan 2012

Proton Dose Calculations In Homogeneous Media, John Wesley Chapman, Jr.

LSU Master's Theses

In this study, a proton pencil beam dose calculation algorithm was developed for a parallel, monoenergetic beam incident on a homogeneous water phantom. Fermi-Eyges theory (Eyges 1948) was used to transport pencil beams, and the characteristic width of elastic scatter events was modeled using the differential Moliere scattering power (Gottschalk 2010). The incorporation of this scattering power formalism allowed our model to account for multiple Coulomb scattering, single scattering, plural scattering, and rigorously accounted for material effects on scatter. Nonelastic nuclear interactions were incorporated into an additional pencil beam model. The attenuation of primary fluence due to nuclear events was …

Collective Security Or World Domination: The Soviet Union And Germany, 1917-1939, Mark Davis Kuss Jan 2012

Collective Security Or World Domination: The Soviet Union And Germany, 1917-1939, Mark Davis Kuss

LSU Doctoral Dissertations

Since the end of World War II, a rather consistent narrative has appeared regarding the origins of this terrible conflict: Hitler started it. The victorious western powers emerged as innocent victims in the titanic struggle while the USSR, once allied to both Hitler and the west, took on the role of principal villain during the Cold War. With the collapse of communism and the partial opening of Soviet archives, a re-assessment appeared, principally under the heading of the “Collective Security School.” As politically incorrect as it may seem, sober reflection indicates that the Soviet Union was actually the peacemaker in …

An Investigation Into Urban Elementary Teachers' Educational Beliefs In Regards To Teaching Writing: Comparing Experiences And Self-Reported Beliefs To Teacher Practices, Shalanda Stanley Jan 2012

An Investigation Into Urban Elementary Teachers' Educational Beliefs In Regards To Teaching Writing: Comparing Experiences And Self-Reported Beliefs To Teacher Practices, Shalanda Stanley

LSU Doctoral Dissertations

This six week study investigated six urban elementary teachers’ educational beliefs in regards to teaching writing, comparing their personal histories as writers with their self-reported beliefs on writing and teaching writing, with that of their teacher practices. A further analysis examined how closely aligned their teacher practices were to research-validated practices. During this ethnographic case study, three questions were explored. These questions were: (a) How do teachers’ personal histories with writing inform their beliefs regarding writing in general, as well as their beliefs on teaching writing?, (b) How do teachers’ educational beliefs in regards to teaching writing inform their instructional …

Shadow Citizens: Felony Disenfranchisement And The Criminalization Of Debt, Ann Cammett Jan 2012

Shadow Citizens: Felony Disenfranchisement And The Criminalization Of Debt, Ann Cammett

Scholarly Works

The disenfranchisement of felons has long been challenged as anti-democratic and disproportionately harmful to communities of color. Critiques of this practice have led to the gradual liberalization of state laws that expand voting rights for those who have served their sentences. Despite these legal developments, ex-felons face an increasingly difficult path to regaining the franchise. This article argues that, for ex-felons in particular, criminal justice debt can serve as an insurmountable obstacle to the resumption of voting rights and broader participation in society. This article uses the term “carceral debt” to identify criminal justice penalties levied on prisoners, “user fees” …

The Role Of Managers Within The Welfare System: How Race And Negative Stereotypes About Clients Affect Managers' Tolerance Of Caseworker Discretion, Alethia Marie Picciola Jan 2012

The Role Of Managers Within The Welfare System: How Race And Negative Stereotypes About Clients Affect Managers' Tolerance Of Caseworker Discretion, Alethia Marie Picciola

LSU Master's Theses

Previous research studies found differences in social welfare policy implementation based on the racial and ethnical differences of clients, workers, and managers. The public perception of welfare recipients being content with living on government money and unmotivated to become self-sufficient is a central theme throughout American culture. The current study examined whether parish-level managers’ personal beliefs about their clients are associated with their tolerance of frontline staff’s discretionary practices. Additionally, the author examined the role that the race of managers plays in the personal beliefs they hold about their clients as well as their tolerance of frontline discretion. This study …

Evading Legislative Jurisdiction, Austen L. Parrish Jan 2012

Evading Legislative Jurisdiction, Austen L. Parrish

Articles by Maurer Faculty

In the last few years, and mostly unnoticed, courts have adopted a radically different approach to issues of legislative jurisdiction. Instead of grappling with the difficult question of whether Congress intended a law to reach beyond U.S. borders, courts have side-stepped it entirely. Courts have done so by redefining the definition of extraterritoriality. Significant and contentious decisions in the Ninth and D.C. Circuits paved the way by holding that not all regulation of overseas foreign conduct is extraterritorial. And then suddenly, last term, the U.S. Supreme Court breathed life into the practice. In its landmark Morrison v. National Australia Bank …

Inside The Seed Of School Accountability: An African-Centered Analysis, Rodrick Lerone Jenkins Jan 2012

Inside The Seed Of School Accountability: An African-Centered Analysis, Rodrick Lerone Jenkins

LSU Doctoral Dissertations

I use Marimba Ani’s Asili concept as defined in Yurugu to examine the school accountability model. By school accountability model, I mean the school model that consists of privately managed “public schools” regulated by state testing programs. I argue that school accountability is essentially oppressive and its success depends on the falsification of African and African American history. Ani explains that Asili is a Kiswalhili term meaning “beginning,” “origin,” “source,” “nature (in the sense of the ‘nature’ of a person or thing),” “essence,” or “fundamental principle.” Furthermore, Ani writes that seed is an “ubiquitous African analogical symbol in African philosophical …

Fatigue Performance Of Existing Bridges Under Dynamic Loads From Winds And Vehicles, Wei Zhang Jan 2012

Fatigue Performance Of Existing Bridges Under Dynamic Loads From Winds And Vehicles, Wei Zhang

LSU Doctoral Dissertations

During the life cycle of bridges, varied amplitude of stress ranges on structural details are induced by the random traffic and wind loads. The progressive deteriorated road surface conditions might accelerate the fatigue damage accumulations. Micro-cracks in structural details might be initiated. An effective structural modeling scheme and a reasonable fatigue damage accumulation rule are essential for stress range acquisitions and fatigue life estimation. The present research targets at the development of a fatigue life and reliability prediction methodology for existing steel bridges under real wind and traffic environment with the capability of including multiple random parameters and variables in …

Photojournalism As Photonationalism, Jeremy Kreusch Jan 2012

Photojournalism As Photonationalism, Jeremy Kreusch

LSU Master's Theses

The public saw the wars in Iraq (2003 – 2012) and Afghanistan (2001 – present) through the lens of reverence and sentimentality toward the soldier. This was manifest not simply in the catchy “support our troops” rhetoric, but in the one-sided depiction of the experience of battle by the photojournalists who worked for the major news organizations in the Western world. From the emotionally bloated to the nationalistic, the photographs taken by “embedded” photojournalists, whether the result of heavy-handed censorship or merely political influence, presented a consistent image: the soldier as a selfless victim of his or her own heroism. …
