Two of the defining behaviors associated with the hominin lineage are an increased reliance on tool use and the routine incorporation of animal tissue in the diet. These adaptations have been linked to numerous downstream consequences including key physiological adaptations as well as social and cognitive effects associated with modern humans. Thus, a critical issue in human evolution is how to determine when hominins began incorporating significant amounts of meat into their diets. Bone surface modifications (BSM) have long been recognized as a powerful inferential tool in identifying the differential involvement of actors responsible for altering assemblages of bone recovered …

In this study, I used critical, qualitative methods to explore how the material and symbolic dynamics of milk banking complicate expectations of organizing and (in)effective lactation. Guided by theories of alternative organizing, in/voluntary membership, the structuration of d/Discourse, and corporeal commodification, I conducted document analysis, fieldwork, and interviews with hospital and milk bank staff and maternal donors and recipients. Results trace the (her)story and protocols of the milk banking industry and examine the circumstances of donation and receipt; the d/Discourses of filth, suspicion, and inadequacy that circulate the lactating, maternal body; and the presence or resistance of commodification within each …

This qualitative study examines second language (L2) writing teachers’ identities. The study explores L2 writing teachers’ narrated identities (i.e., the teachers’ perceptions of themselves), enaction of these identities (i.e., students’ perceptions of those teachers; those teachers’ classroom behaviors), and identity enaction’s positive impacts on students. In order to investigate these issues, I conducted interviews with three L2 writing teachers of first-year composition in the United States (U.S.), along with student interviews and classroom observations. Findings showed that there were 10 narrated identities of these L2 writing teachers. All of these narrated identities were enacted except for one. The findings also …

Proteins are, arguably, the most complicated molecular machines found in nature. From the receptor proteins that decorate the exterior of cell membranes to enzymes that catalyze the slowest of chemical reactions, proteins perform a wide variety of essential biological functions. A reductionist view of proteins as a macromolecular group, however, may hold that they simply interact with other chemical species. Notably, proteins interact with other proteins, other biological macromolecules, small molecules, and ions. This in turn makes proteins uniquely qualified for use technological use as sensors of said chemical species (biosensors). Several methods have been developed to convert proteins into …

Providing an environmental context to early hominins is as important as describing the hominin fossils themselves, because evolutionary processes are tightly linked to everchanging ecosystems that vary across space and through time. An optimal understanding of ecosystems changes is critical to formulate and test hypotheses regarding human evolution and adaptation. Fortunately, the fossil record has yielded abundant remains of mammals which can be used to explore the possible causal relationships between environmental change and mammal – including hominin –evolution. Although many studies have already been conducted on this topic, most of them are framed at large spatial and temporal scales. …

Louis Hector Berlioz (1803-1869) was a pioneer of 19th century Romanticism in France. In the mid-19th century, he broke the traditional mold by connecting poetry and music through French song. This development transformed French song from the simple and structured Romance of the 18th century into the structural freedom of what he established as the a Mélodie. His song cycle Les nuits d’été, op 7 was composed first for voice and piano in 1841 and later arranged for voice and orchestra in 1856. After the 1856 orchestral version was completed, Les nuits d’été received greater recognition than it had from …

With the rise of Posttraumatic Stress Disorder (PTSD) among adults in the United States, understanding the processes of trauma, trauma related disorders, and the long-term impact of living with them is an area of continued focus for researchers. This is especially a concern in the case of current and former military service members (veterans), whose work activities and deployment cycles place them at an increased risk of exposure to trauma-inducing experiences but who have a low rate of self-referral to healthcare professionals. There is thus an urgent need for developing procedures for early diagnosis and treatment. The present study examines …

当今中国,人口老龄化趋势正驱动卫生总费用快速攀升,国家医保基金可持续性面临挑战。从卫生费用结构来看,中国长期以来存在药品费用占卫生总费用比例高、用药结构相对不合理等问题,限制了基金使用效率的提升,不利于医保基金的可持续发展。医保控费尤其是控制药品花费的必要性日益凸显。2018年末,新组建的国家医保局在“4+7城市”启动了国家药品集中采购试点工作,通过“量价挂钩”“以量换价”的形式,实现了25个药品品种的大幅降价,在减轻患者经济负担、节省医保费用、净化流通环境等方面成效显著。可以预期,在医保控费压力下,以带量采购为核心的集中采购将成为一项长期的政策选项。与此同时,该项政策将通过对价格信号的重大调整和采购量的重新分配重塑市场格局,对制药产业和制药企业产生深刻影响。因此,对集中采购政策的实施影响进行全面、审慎的评估,一方面能形成对集中采购政策执行现状的深刻理解,另一方面也能基于政策实施后的产业影响,对推广实施集中采购政策形成针对性建议。 本文通过文献梳理、案例研究、问卷分析和回归预测分析等多元研究方法,对国家药品集中采购试点政策实施后对制药企业和制药行业的影响进行了深入分析。研究发现,在企业层面,受制于本国制药企业发展阶段和价格下降导致的利润压缩,国家集中采购试点政策将在一定程度上影响中标药品对于大量中国患者需求的满足并对中标药品的质量控制形成一定压力;产业层面,由于价格下降和市场格局变动导致企业预期变化,国家集中采购试点政策将使得仿制药企业对待药品的“质量和疗效一致性评价”更为审慎,短期内在被采购的药物分子领域形成一家独大的局面,长远将导致行业集中度的进一步提高。针对上述研究发现。 本文分别从带量采购政策的政策设计、带量采购中标药品质量监管政策和仿制药产业鼓励政策等维度提出了相应优化建议。建议政府在带量采购政策设计上坚持分类采购原则,强化中标企业产能、产量的核实,加大自由竞争市场份额,合理划分带量采购片区,避免医院采用“一刀切”的政策使用中标药;在质量监管上加强针对性质量监管,运用风险工具进行评估,针对高危风险制定风险最小化措施,加强推进ICH Q10在仿制药企业中的落地;在仿制药产业鼓励政策上落实“质量和疗效一致性评价”鼓励政策,为高质量仿制药提供积极的市场环境,优化流通环节费率计算方式。 Dissertation/Thesis

A complex social system, whether artificial or natural, can possess its macroscopic properties as a collective, which may change in real time as a result of local behavioral interactions among a number of agents in it. If a reliable indicator is available to abstract the macrolevel states, decision makers could use it to take a proactive action, whenever needed, in order for the entire system to avoid unacceptable states or con-verge to desired ones. In realistic scenarios, however, there can be many challenges in learning a model of dynamic global states from interactions of agents, such as 1) high complexity …

Governance of complex social-ecological systems is partly characterized by processes of autonomous decision making and voluntary mutual adjustment by multiple authorities with overlapping jurisdictions. From a policy perspective, understanding these polycentric processes could provide valuable insight for solving environmental problems. Paradoxically, however, polycentric governance theory seems to proscribe conventional policy applications: the logic of polycentricity cautions against prescriptive, top-down interventions. Water resources governance, and large-scale water infrastructure systems in particular, offer a paradigm for interpretation of what Vincent Ostrom called the “counterintentional and counterintuitive patterns” of polycentricity. Nearly a century of philosophical inquiry and a generation of governance research into …

Nonregular designs are a preferable alternative to regular resolution four designs because they avoid confounding two-factor interactions. As a result nonregular designs can estimate and identify a few active two-factor interactions. However, due to the sometimes complex alias structure of nonregular designs, standard screening strategies can fail to identify all active effects. In this research, two-level nonregular screening designs with orthogonal main effects will be discussed. By utilizing knowledge of the alias structure, a design based model selection process for analyzing nonregular designs is proposed.

This research explores tests for statistical suppression. Suppression is a statistical phenomenon whereby the magnitude of an effect becomes larger when another variable is added to the regression equation. From a causal perspective, suppression occurs when there is inconsistent mediation or negative confounding. Several different estimators for suppression are evaluated conceptually and in a statistical simulation study where we impose suppression and non-suppression conditions. For each estimator without an existing standard error formula, one was derived in order to conduct significance tests and build confidence intervals. Overall, two of the estimators were biased and had poor coverage, one worked well …

Lattice-based Cryptography is an up and coming field of cryptography that utilizes the difficulty of lattice problems to design lattice-based cryptosystems that are resistant to quantum attacks and applicable to Fully Homomorphic Encryption schemes (FHE). In this thesis, the parallelization of the Residue Number System (RNS) and algorithmic efficiency of the Number Theoretic Transform (NTT) are combined to tackle the most significant bottleneck of polynomial ring multiplication with the hardware design of an optimized RNS-based NTT polynomial multiplier. The design utilizes Negative Wrapped Convolution, the NTT, RNS Montgomery reduction with Bajard and Shenoy extensions, and optimized modular 32-bit channel arithmetic …

Elucidation of Antigen-Antibody (Ag-Ab) interactions is critical to the understanding of humoral immune responses to pathogenic infection. B cells are crucial components of the immune system that generate highly specific antibodies, such as IgG, towards epitopes on antigens. Serum IgG molecules carry specific molecular recognition information concerning the antigens that initiated their production. If one could read it, this information can be used to predict B cell epitopes on target antigens in order to design effective epitope driven vaccines, therapies and serological assays. Immunosignature technology captures the specific information content of serum IgG from infected and uninfected individuals on high …

Communications between air traffic controllers and pilots are critical to national airspace traffic management. Measuring communications in real time made by pilots and air traffic controllers has the potential to predict human error. In this thesis a measure for Deviations from Closed Loop Communications is defined and tested to predict a human error event, Loss of Separation (LOS). Six retired air traffic controllers were recruited and tested in three conditions of varying workload in an Terminal Radar Approach Control Facility (TRACON) arrival radar simulation. Communication transcripts from simulated trials were transcribed and coding schemes for Closed Loop Communication Deviations (CLCD) …

Derived from the Greek word soma, meaning body, somatics is a field of movement methodologies designed to promote a greater sense of physical self-awareness through kinesthetic learning. Gaga Movement Language and Bartenieff Fundamentals, two methodologies based on somatic principles, offer unique processes to develop an individual’s movement vocabulary. By synthesizing Gaga Movement Language and Bartenieff Fundamentals with vocal pedagogy and vocal repertoire, singers can develop a kinesthetic awareness of their vocal technique that informs their artistic expression, movement vocabulary, and performance ability. This paper presents a model for a Voice Somatics Integration Lab (VSI Lab), geared toward voice performance majors …

Positioned between Beethoven and Liszt in the golden period, Carl Czerny (1791-1857) played a significant historical role in the area of piano pedagogy. Many pianists are familiar with and have played Czerny’s études, or technical exercises. However, few delve into Czerny’s piano works for performance, including eleven piano sonatas and more than 180 works titled variations. The project at hand examines three of Carl Czerny’s variation works for piano: Opus 33 (on a theme of Rode), Opus 281 (on a theme from Bellini’s Norma, in its solo piano version), and Opus 292 (on an original theme). These works are explored …

Power management circuits have been more and more widely used in various applications, while providing fully integrated voltage regulation remains a challenging topic. Switched-capacitor (SC) voltage converters have received attentions in integrated power conversion for fixed-ratio voltage conversions with good efficiency and feasibility of integration. During my PhD study, an on-chip current sensing technique is proposed to dynamically modulate both switching frequency and switch widths of SC voltage converters, enhancing fast transient response and higher efficiency across a wide range of load currents. In conjunction with SC converters, a low-dropout regulator (LDO) is implemented which is driven by a push-pull …

This research focuses mainly on employing tunable materials to achieve dynamic radiative properties for spacecraft and building thermal management. A secondary objective is to investigate tunable materials for optical propulsion applications. The primary material investigated is vanadium dioxide (VO2), which is a thermochromic material with an insulator-to-metal phase transition. VO2 typically undergoes a dramatic shift in optical properties at T = 341 K, which can be reduced through a variety of techniques to a temperature more suitable for thermal control applications. A VO2-based Fabry-Perot variable emitter is designed, fabricated, characterized, and experimentally demonstrated. The designed emitter has high emissivity when …

The purpose of this document is to identify contemporary issues facing female-identifying professional trombonists today. Interviews were conducted with three prominent women in the international trombone community, including questions that sought to foster discussion on the extent to which their experience as professional trombonists was influenced by their gender. The topic of microaggressions emerged as significant, as it became clear throughout the interview process that these women experience microaggressions far more commonly than overt gender discrimination, as did the topic of coping mechanisms. The interview questions also sparked discussions of identity, self-motivation, and local cultural norms within the context of …
