Why Should Law And Policy Makers Understand Extremist Beliefs? The Islamic State (Isis) As A Case Study: Past, Present, And Future, Ali Rod Khadem

Lewis & Clark Law Review

The overarching argument in this Article is that inadequate comprehension of extremist doctrines undermines efforts in law and policy. Selecting the Islamic State (ISIS) as a case study, this Article attempts to resolve three legal and policy dilemmas by exposing internal ISIS doctrine (i.e. by considering the perspectives of the movement itself). This focus on ISIS is justified, for despite the movement’s recent territorial decline, it is precisely its doctrine and ideology that will persist and enable the rise of 2.0 and 3.0 movements modeled after the prototype. In considering ISIS, the aim here is to demonstrate the general need …

TELA included pulmonary vein isolation, LA dome lesions and LA appendage exclusion. All (n = 55) patients received an implantable loop recorder (ILR), 30 days post-operatively. Antiarrhythmic and anticoagulation therapy were discontinued at 90 and 180 days postoperatively, respectively, if patients were free of …

Can Religiosity Be Explained By ‘Brain Wiring’? An Analysis Of Us Adults’ Opinions, Sharan Kaur Mehta, Christopher P. Scheitle, Elaine Howard Ecklund

Faculty & Staff Scholarship

Studies examining how religion shapes individuals’ attitudes about science have focused heavily on a narrow range of topics, such as evolution. This study expands this literature by looking at how religion influences individuals’ attitudes towards the claim that neuroscience, or “brain wiring,” can explain differences in religiosity. Our analysis of nationally representative survey data shows, perhaps unsurprisingly, that religiosity is negatively associated with thinking that brain wiring can explain religion. Net of religiosity, though, individuals reporting religious experiences are actually more likely to agree that brain wiring can explain religiosity, as are individuals belonging to diverse religious traditions when compared …

Controlling The Transverse Proton Relaxivity Of Magnetic Graphene Oxide, Bibek Thapa, Daysi Diaz-Diestra, Dayra Badillo-Diaz, Rohit Kumar Sharma, Kiran Dasari, Shalini Kumari, Mikel B. Holcomb, Juan Beltran-Huarac, Brad R. Weiner, Gerardo Morell

Faculty & Staff Scholarship

The engineering of materials with controlled magnetic properties by means other than a magnetic feld is of great interest in nanotechnology. In this study, we report engineered magnetic graphene oxide (MGO) in the nanocomposite form of iron oxide nanoparticles (IO)-graphene oxide (GO) with tunable core magnetism and magnetic resonance transverse relaxivity (r2). These tunable properties are obtained by varying the IO content on GO. The MGO series exhibits r2 values analogous to those observed in conventional single core and cluster forms of IO in diferent size regimes—motional averaging regime (MAR), static dephasing regime (SDR), and echo-limiting regime (ELR) or slow …

Water‐Borne And Plasma Corticosterone Are Not Correlated In Spotted Salamanders, Alice R. Millikin, Sarah K. Woodley, Drew R. Davis, Ignacio T. Moore, James T. Anderson

Faculty & Staff Scholarship

Water‐borne hormone measurement is a noninvasive method suitable for amphibians of all sizes that are otherwise difficult to sample. For this method, containment‐water is assayed for hormones released by the animal. Originally developed in fish, the method has expanded to amphibians, but requires additional species‐specific validations. We wanted to determine physiological relevance of water‐borne corticosterone in spotted salamanders (Ambystoma maculatum) by comparing concentrations to those taken using established corticosterone sampling methods, such as plasma. Using a mixture of field and laboratory studies, we compared water‐borne corticosterone levels to other traditional methods of sampling corticosterone for spotted salamander larvae, …

Soil And Tree Nutrient Status Of High Elevation Mixed Red Spruce (Picea Rubens Sarg.) And Broadleaf Deciduous Forests, Phillip M. Crim, Louis M. Mcdonald, Jonathan R. Cumming

Faculty & Staff Scholarship

Abstract: Anthropogenic and industrial emissions have resulted in historically high levels of acidic deposition into central Appalachian forests. Despite the reduction in acidic inputs due to legislation curbing industrial emissions in the United States, continued N deposition may impact forest ecosystems. Soil and foliar samples were collected from four high elevation red spruce sites along a modeled gradient of historic N deposition. The three most abundant tree species at all sites, Acer rubrum L., Betula alleghaniensis Britt., and Picea rubens Sarg., were sampled. Bulk soil beneath the canopies of individual trees were collected from the top 15-cm and separated into …

Characterization And Quantification Of Major Flavonol Glycosides In Ramps (Allium Tricoccum), Wijdan M. Dabeek, Nik Kovinich, Callee Walsh, Melissa Ventura Marra

Faculty & Staff Scholarship

The ramp (Allium tricoccum) is a traditional plant in the eastern Appalachian Mountains. Ramps have been used in traditional medicine for their health-promoting roles in lowering blood pressure and cholesterol. Information on the chemical composition of the potentially bioactive components in ramps is limited. Therefore, the aim of this work was to characterize and quantify major flavonols in ramps. Flavonoids were extracted in 50% methanol and 3% acetic acid. Characterization was conducted using UHPLC-PDA-MS and MS/MS, and quantification was performed using UHPLC-PDA detection. The major flavonol glycosides were kaempferol sophoroside glucuronide, quercetin sophoroside glucuronide, kaempferol rutinoside glucuronide, quercetin hexoside glucuronide, …

An Elastic-Net Logistic Regression Approach To Generate Classifiers And Gene Signatures For Types Of Immune Cells And T Helper Cell Subsets, Arezo Torang, Paraag Gupta, David J. Klinke Ii

Faculty & Staff Scholarship

Background: Host immune response is coordinated by a variety of different specialized cell types that vary in time and location. While host immune response can be studied using conventional low-dimensional approaches, advances in transcriptomics analysis may provide a less biased view. Yet, leveraging transcriptomics data to identify immune cell subtypes presents challenges for extracting informative gene signatures hidden within a high dimensional transcriptomics space characterized by low sample numbers with noisy and missing values. To address these challenges, we explore using machine learning methods to select gene subsets and estimate gene coefficients simultaneously. Results: Elastic-net logistic regression, a type of …

"I'D Rather Beg For Forgiveness Than Ask For Permission": Sexuality Education Teachers' Mediated Agency And Resistance, Marilyn Preston

Open Access Publishing Support Funded Articles

This study explores sexuality education teachers' identities and examines the ways in which teachers' experiences mediate their agency and resistance in classrooms. Using grounded theory methodology, the study explores the identities and experiences of school-based sexuality education teachers throughout the United States. Findings suggest that the teachers rely on a unique sense of identity in order to justify challenging the regulatory and policy limitations to their curricula. The study illustrates how agency is mediated by individual social location and experience.

Overview Of Big Data-Intensive Storage And Its Technologies For Cloud And Fog Computing, Richard S. Segall, Jeffrey S. Cook, Gao Niu

Faculty Publications

Computing systems are becoming increasingly data-intensive because of the explosion of data and the needs for processing the data, and subsequently storage management is critical to application performance in such data-intensive computing systems. However, if existing resource management frameworks in these systems lack the support for storage management, this would cause unpredictable performance degradation when applications are under input/output (I/O) contention. Storage management of data-intensive systems is a challenge. Big Data plays a most major role in storage systems for data-intensive computing. This article deals with these difficulties along with discussion of High Performance Computing (HPC) systems, background for storage …

The Transformation Of Marriage As A State Institution, John Makdisi, June Mary Zekan Makdisi

Faculty Articles

The first section of this essay explores why the good of children requires the institution of marriage to promote the procreation of children by the act of physical-spiritual love between a man and a woman. The second section explores why the good of children requires the institution of marriage to promote the upbringing of children by the lasting, exclusive, and faithful commitment of the couple. The third section explains why Obergefell's removal of the requirement of a legal union between a man and a woman as an essential aspect of marriage not only destroys the function of the marriage institution …

Intrapulmonary Inoculation Of Multicellular Tumor Spheroids To Construct An Orthotopic Lung Cancer Xenograft Model That Mimics Four Clinical Stages Of Non-Small Cell Lung Cancer, Yingbo Huang

University of the Pacific Theses and Dissertations

Lung cancer leads in mortality among all types of cancer in the US and Non-small cell lung cancer (NSCLC) is the major type of lung cancer. Immuno-compromised mice bearing xenografts of human lung cancer cells represent the most common animal models for studying lung cancer biology and for evaluating potential anticancer agents. However, orthotopic lung cancer models based on intrapulmonary injection of suspended cancer cells feature premature leakage of the cancer cells to both sides of the lung within five days, which generates a quick artifact of metastasis and thus belies the development and progression of lung cancer as seen …

Characterization And Analysis Of Proteins Secreted By The Mutant Pichia Pastoris Strain, Bgs13, Christopher Alan Naranjo

University of the Pacific Theses and Dissertations

The methylotrophic yeast Pichia pastoris has been utilized for heterologous protein expression for research, clinical, and industrial purposes to produce thousands of recombinant protein products. Because P. pastoris secretes very few of its own proteins, the exported recombinant protein is the major polypeptide in the extracellular medium, making purification relatively easy. Unfortunately, a disadvantage to the programmed export is that some recombinant proteins intended for secretion are retained within the cell and may be subsequently degraded. A mutant strain isolated in our lab, containing a pREMI-derived disruption of the BGS13 gene, has displayed elevated levels of secretion for a variety …

Effects Of Eye Tracking During Infancy On Social Ambiguity And Emotional Distress, Gabriela Hernandez

University of the Pacific Theses and Dissertations

The purpose of this study was to investigate the relationship between early eye tracking and later non-suicidal self-injury, and whether this relationship was negatively impacted by distress and impulsivity, and conversely alleviated by emotional regulation and problem solving abilities. Briggs-Gowan et al. (2001) found that young children with recurrent and comorbid externalizing and internalizing problems have the most impairment; they exhibit greater difficulty with emotional stability, and require greater utilization of mental health services. Little research has focused on the relationship between eye tracking in early infancy and suicidal self-injurious (NSSI) behavior in early childhood. Multiple regression analysis was used …

Department of Agronomy and Horticulture: Faculty Publications

Broomcorn millet (Panicum miliaceum L.) is the most water-efficient cereal and one of the earliest domesticated plants. Here we report its high-quality, chromosome-scale genome assembly using a combination of short-read sequencing, single-molecule real-time sequencing, Hi-C, and a high-density genetic map. Phylogenetic analyses reveal two sets of homologous chromosomes that may have merged ~5.6 million years ago, both of which exhibit strong synteny with other grass species. Broomcorn millet contains 55,930 proteincoding genes and 339 microRNA genes. We find Paniceae-specific expansion in several subfamilies of the BTB (broad complex/tramtrack/bric-a-brac) subunit of ubiquitin E3 ligases, suggesting enhanced regulation of protein dynamics …

Applicability Of The Dual Isotopes Δ15n And Δ18o To Identify Nitrate In Groundwater Beneath Irrigated Cropland, R. F. Spalding, A. J. Hirsh, M. E. Exner, N. A. Little, K. L. Kloppenborg

Department of Agronomy and Horticulture: Faculty Publications

Identification of the nitrate sources that adversely impact groundwater quality is a necessary first step in the control of this major worldwide pollutant. The impact of nitrate leachate from urea-ammonium nitrate (UAN) (50% urea-N, 25% ammonium-N, 25% nitrate-N) fertilizer, whose use has increased dramatically in the last three decades largely because it can be applied through sprinkler irrigation systems to corn in all growth stages, is investigated. The dual isotopes δ¹⁵N_NO3 and δ¹⁸O_NO3 were measured in groundwater samples from 39 irrigation wells in two intensively sprinkler-irrigated, corn-growing areas of Nebraska with nitrate-contaminated (N …

Restoring Fire-Grazer Interactions To Pursue Heterogeneity In Sandhills Prairie, Jack R. Arterburn, Dirac L. Twidwell Jr, Carissa L. Wonkka, Walter H. Schacht, David A. Wedin

Department of Agronomy and Horticulture: Faculty Publications

Heterogeneity has emerged as a fundamental principle for grassland management and the importance of environmental heterogeneity for biological diversity has raised questions about the appropriateness of grassland practices that seek to promote uniform grassland structure and composition. Principles of uniformity in grassland management reflect a utilitarian target of “managing for the middle” by minimizing both overgrazing and underutilization while avoiding or preventing fire and other disturbances that consume aboveground biomass. We evaluated pioneering efforts to restore fire-grazer interactions via patch burning in an effort to increase spatial heterogeneity at the patch scale in the Nebraska Sandhills, a sandy soil, mixed-grass …

Spatial Imaging And Screening For Regime Shifts, Daniel R. Uden, Dirac Twidwell, Craig R. Allen, Matthew O. Jones, David E. Naugle, Jeremy D. Maestas, Brady W. Allred

Department of Agronomy and Horticulture: Faculty Publications

Screening is a strategy for detecting undesirable change prior to manifestation of symptoms or adverse effects. Although the well-recognized utility of screening makes it commonplace in medicine, it has yet to be implemented in ecosystem management. Ecosystem management is in an era of diagnosis and treatment of undesirable change, and as a result, remains more reactive than proactive and unable to effectively deal with today’s plethora of non-stationary conditions. In this paper, we introduce spatial imaging-based screening to ecology. We link advancements in spatial resilience theory, data, and technological and computational capabilities and power to detect regime shifts (i.e., vegetation …

Development Of Cooperative Photocatalysts, Tossapong Phuangburee

Chulalongkorn University Theses and Dissertations (Chula ETD)

Photosynthesis involves electron/energy transfer between photocatalyst and catalyst. This concept called “cooperative photocatalyst” is of interest for researchers to develop sustainable photocatalytic systems. In this dissertation, two catalytic systems including graphene oxide (GO) and copper complexes as catalysts were combined with photocatalysts to achieve alcohol oxidation and atom-transfer radical addition (ATRA), respectively. In the first system, GO was modified with porphyrin derivatives (TPP or ZnTPP) using sonication method. The prepared composites were characterized by spectroscopic techniques such as UV-Vis, FTIR, Raman spectroscopy. The photocatalytic activity of the GO-ZnTPP was significantly lower than that of GO-TPP due to the interactions between …

Recolonization Of Mollusc Assemblages In Mangrove Plantations Damaged By Typhoon Chan-Hom In The Philippines, Severino G. Salmo Iii, Ian R. Tibbetts, Norman C. Duke

Environmental Science Faculty Publications

We investigated the effects of a catastrophic typhoon on mollusc assemblages of damaged mangrove plantations of different ages. Molluscs were sampled from infaunal, epifaunal and arboreal assemblages of mangrove stands in Lingayen Gulf, northwest Philippines, and compared with assemblages of un-impacted areas. Prior to the occurrence of the typhoon, there were clear shifts in the species diversity (H’) and composition of mollusc assemblages with stand age of mangrove forests. This was observed in species composition through the succession in dominance from pioneer to seral or putative climax species, and assemblage type (as arboreal, epifaunal and infaunal). However, severe damage to …

A New Process For Integrating Foreign Physicians Into American Healthcare, Rachel J. Cruz Nieves

USF St. Petersburg campus Honors Program Theses (Undergraduate)

The United States of America is a nation with a population of 328 million (US census Bureau). The latest reports by the American Association of Medical Colleges shows, however, that only 860,939 licensed and practicing physicians serve this large population. These numbers articulate a ratio of one doctor for every 381 patients. By comparison, Cuba has an average of 591 physicians per 100,000 people, which translates to 169 people per physician. These proportions illustrate how the United States is lagging behind on providing the American population with sufficient physicians to meet their medical needs. While this on its own is …

The Theological Significance Of The Relations Of Freedom And Time In The Sciences And Humanities: An Evaluation Of The Contributions Of David Bohm And Pauli Pylkko, Michael F. Younker

Dissertations

The concepts of freedom and time underlay all other philosophical and theological questions. This dissertation addresses the natures and relations of freedom and time and their impact upon theological reflection, primarily through the works of the philosopher of science, David Bohm and the philosopher of the humanities, Pauli Pylkkö. These two representatives come from the two competing cultures of the sciences and humanities, which illustrate the deep philosophical conflict that has emerged between these cultures concerning the natures of freedom and time. Specifically, the paradigmatic contributions of Albert Einstein's four-dimensional 'timeless space-time' (with timeless freedom) alongside Bohm, on the one …
