Australopiths exhibit a number of derived facial features that are thought to strengthen the face against high and/or repetitive loads associated with a diet that included mechanically challenging foods. Here, we use finite element analysis (FEA) to test hypotheses related to the purported strengthening role of the zygomatic root and "anterior pillar" in australopiths. We modified our previously constructed models of Sts 5 (Australopithecus africanus) and MH1 (A. sediba) to differ in the morphology of the zygomatic root, including changes to both the shape and positioning of the zygomatic root complex, in addition to creating variants of Sts 5 lacking …

Complex Adaptive Behavior Of Hybrid Teams, Mustafa Canan, Andres Sousa-Poza, Anthony Dean

Engineering Management & Systems Engineering Faculty Publications

The challenges in uncertain, dynamic and complex military operation environments exceed the problem-solving capabilities of individuals. Problem-solving has become a team task. These [hybrid] teams, which typically include machine and human elements, utilize autonomy and artificial intelligence to enhance the quality of actionable information and decision-making capabilities in solving complex problems. For this to be effective, shared mental models must be developed by teams. This demands adaptive behavior of team members to establish a common understanding, and its members to respond to the changes in complex dynamic environments.

In this paper, we introduce a mathematical formalization of an interaction platform …

Overview Of Metrics, Models, And Simulation For Cyber-Physical Systems, Barry C. Ezell, Luanne Burns Chamberland

VMASC Publications

The metric, models, and simulation for Cyber-Physical Systems focuses on the different frameworks that have been operationalized so that cyber-physical systems can be baselined in security. In addition, the minitrack is interest in innovations in decision support such as cost effective means to decide what metrics should be addressed to get the best value in cybersecurity. There are many challenges to overcome in cyber-physical systems. We ask: How should frameworks be operationalized? What methodologies are available to quantify cybersecurity frameworks while accounting for cyber-physical interactions into account.

Creative Confidence In Organizational Knowledge Creation: A Synthesis Of The Literature, Elnaz Dario, Rafael Landaeta, Resit Unal, E.H. Ng. (Ed.), B. Nepal (Ed.), E. Schott (Ed.)

Engineering Management & Systems Engineering Faculty Publications

Creative confidence is a newly rising topic in the innovation study area. In a world where creativity has become a vital source of knowledge creation, not believing in one's own creative capacity could be a barrier. At the organizational level, many good ideas are disappearing before ever being written down or shared. Organizations may lose talented people who have great creative potential by either not giving them the opportunity to express their creative ideas or due to a lack of confidence from the employee side, in sharing these ideas. This paper will contribute to the research stream on the role …

A two-step clustering methodology was used for grouping courses based on academic performance and context similarities. The clustering methodology results are validated by discriminant analysis. Student movements among clusters over the four years are identified …

Beyond Administrative Tunnel Vision: Widening The Lens Of Costs And Benefits, Govind Persad

Publications

Choices in one sector or department of public policy, such as health, frequently produce costs and benefits in other sectors, such as education or the environment. In this article, I argue that administrators should not make decisions in ways that ignore effects on other policy sectors, and arguablythough more debatably-should not give special priority to the interests of their own sector In Part I, I review contexts where administrators are directed to ignore or give a lower priority to effects on other policy sectors. In Part II, I lay out an argument that agencies should not ignore these effects (using …

Averting Robot Eyes, Margot Kaminski, Matthew Rueben, William D. Smart, Cindy M. Grimm

Publications

Home robots will cause privacy harms. At the same time, they can provide beneficial services—as long as consumers trust them. This Essay evaluates potential technological solutions that could help home robots keep their promises, avert their eyes, and otherwise mitigate privacy harms. Our goals are to inform regulators of robot-related privacy harms and the available technological tools for mitigating them, and to spur technologists to employ existing tools and develop new ones by articulating principles for avoiding privacy harms.

We posit that home robots will raise privacy problems of three basic types: (1) data privacy problems; (2) boundary management problems; …

Achieving American Retirement Prosperity By Changing Americans' Thinking About Retirement, Peter H. Huang

Publications

There are many decisions that Americans have to make about retirement before, at, and after retirement. For example, Americans have to decide when to start saving for retirement, how much to save, how to invest those savings, when to retire, when to claim social security, and how to take required minimum distributions from 401(k) plans or Individual Retirement Accounts. Different things can go wrong at each of these decisions for different reasons. Many Americans, for various reasons, including insufficient energy, money, motivation, time, and understanding, do no retirement planning. Some Americans do some retirement planning, yet worry they are doing …

The Wages Of Genetic Entitlement: The Good, The Bad, And The Ugly In The Rape Survivor Child Custody Act, Jennifer S. Hendricks

Publications

This Essay analyzes flaws and assumptions in the recently enacted Rape Survivor Child Custody Act. The RSCCA offers a window into the problems with defining parenthood in terms of genes instead of caretaking relationships, which is what led to the problem of rapists being able to claim parental rights in the first place. Rather than address that underlying defect in family law, the statute attempts a solution that might work if all rapists were strangers, all rapists were men, and all rape victims were women, but glosses over complicated problems of violence and coercion in relationships. Despite this failure to …

The Chow: Depictions Of The Criminal Justice System As A Character In Crime Fiction, Marianne Wesson

Publications

Having been honored by a request to contribute to a Symposium honoring my talented friend Alafair Burke, I composed this essay describing the various ways the criminal justice system has been depicted in English-language crime fiction. This survey, necessarily highly selective, considers portrayals penned by writers from Dickens to Tana French. Various dimensions of comparison include the authors’ apparent beliefs about the rule of law (from ridiculously idealistic to uncompromisingly cynical), the characters’ professional perspectives (private detective, police officer, prosecutor, defense lawyer, judge, victim, accused), and the protagonists’ status as institutional insiders or outsiders or occupants of the uncomfortable middle. …

Operationalizing Free, Prior, And Informed Consent, Carla F. Fredericks

Publications

The UN Declaration on the Rights of Indigenous Peoples (UNDRIP) has acknowledged varying ways in which international actors can protect, respect and remedy the rights of indigenous peoples. One of these methods is the concept of free, prior and informed consent (FPIC) as described in Articles 10, 19, 28 and 29. There has been much debate in the international community over the legal status of the UNDRIP, and member states have done little to implement it. In applied contexts, many entities like extractive industries and conservation groups are aware of risks inherent in not soliciting FPIC and have endeavored to …

Agency Law And The New Economy, Mark J. Loewenstein

Publications

This article considers the status of workers in the "new economy," defined as the sharing economy (e.g., Uber, Lyft) and the on-demand economy. The latter refers to the extensive and growing use of staffing companies by established businesses in many different industries to provide all or a portion of their workforce. Workers in both the sharing economy and the on-demand economy are, generally speaking, at a disadvantage in comparison to traditional employees. Uber drivers, for example, are typically considered independent contractors, not employees, and therefore are not covered under federal and state laws that protect or provide benefits to employees. …

Fathers And Feminism: The Case Against Genetic Entitlement, Jennifer S. Hendricks

Publications

This Article makes the case against a nascent consensus among feminist and other progressive scholars about men's parental rights. Most progressive proposals to reform parentage law focus on making it easier for men to assert parental rights, especially when they are not married to the mother of the child. These proposals may seek, for example, to require the state to make more extensive efforts to locate biological fathers, to require pregnant women to notify men of their impending paternity, or to require new mothers to give biological fathers access to infants.

These proposals disregard the mother's existing parental rights and …

Health Information Equity, Craig Konnoth

Publications

In the last few years, numerous Americans’ health information has been collected and used for follow-on, secondary research. This research studies correlations between medical conditions, genetic or behavioral profiles, and treatments, to customize medical care to specific individuals. Recent federal legislation and regulations make it easier to collect and use the data of the low-income, unwell, and elderly for this purpose. This would impose disproportionate security and autonomy burdens on these individuals. Those who are well-off and pay out of pocket could effectively exempt their data from the publicly available information pot. This presents a problem which modern research ethics …

Who Needs Contracts? Generalized Exchange Within Investment Accelerators, Brad Bernthal

Publications

This Article investigates why an expert volunteers on behalf of startups that participate in a novel type of small venture capital (“VC”) fund known as a mentor-driven investment accelerator (“MDIA”). A MDIA organizes a pool of seasoned individuals – called “mentors” – to help new companies. An obvi- ous organizational strategy would be to contract with mentors. Mentors in- stead voluntarily assist. Legal studies of norm-based exchanges do not explain what this Article calls the “mentorship conundrum”—i.e., the puzzling moti- vation of a mentor to volunteer within otherwise for-profit environments. This Article is the first to bridge the insights of …

Performative Privacy, Scott Skinner-Thompson

Publications

Broadly speaking, privacy doctrine suggests that the right to privacy is non-existent once one enters the public realm. Although some scholars contend that privacy ought to exist in public, “public privacy” has been defended largely with reference to other, ancillary values privacy may serve. For instance, public privacy may be necessary to make the freedom of association meaningful in practice.

This Article identifies a new dimension of public privacy, supplementing extant justifications for the right, by arguing that many efforts to maintain privacy while in “public” are properly conceptualized as forms of performative, expressive resistance against an ever-pervasive surveillance society. …

Bragg Gratings In Polarization Maintaining Optical Fiber As Three Dimensional Strain Sensor, Joel Quintana

Open Access Theses & Dissertations

Fiber-Bragg Gratings (FBG) for Structural Health Monitoring (SHM) have been studied extensively as they offer electrically passive operation, electromagnetic interference (EMI) immunity, high sensitivity and multiplexing as compared to conventional electric strain sensors. FBG sensors written within polarization maintaining (PM) optical fiber offer ad- ditional dimensions of strain measurement, greatly reducing the number of sensors needed to properly monitor a structure. This reduction however, adds complexity to the dis- crimination of the sensorâ??s optical response to its corresponding applied strains. This Dissertation defines the set of algorithms needed to measure planar strain using PM-FBGs exclusively. It defines the minimum number …

Optimization Of Collagen Microneedle Using Taguchi Method, Abhilash Aditya

Open Access Theses & Dissertations

Research is conducted to create dissolving collagen microneedles and to optimize the parameters for close to perfect dimension microneedles. A collagen microneedle patch has been developed with a micro-manufacturing process (micro-molding process). The collagen microneedles, varying in length from 300 to 600-μm may reach different targeted layers of the skin depending on the application. As the microneedles penetrate the skin they dissolve, delivering collagen through the epidermis. Such addition of collagen directly to the dermis layers allows it to be absorbed, increasing skin's strength and resilience, since it is one of the natural components of the younger looking skin. This …

An In-Depth Evaluation Of Shear Box Compactor For Hot Mix Asphalt, Isaac Jaime Aguilar

Open Access Theses & Dissertations

Asphalt pavement is present in each roadway in every town or city today and it is paramount to properly design pavement to efficiently reduce its deterioration. To determine how pavement fails, pavement specimens prepared in the laboratory undergo performance tests which demonstrate the pavements strength and durability. Performance tests require little variability from compacted specimens, and it is critical to have a compaction method which is similar to field compaction and produces homogenous specimens. Currently, laboratory performance test specimens are obtained with the Superpave Gyratory Compactor (SGC). That device has few similarities to the rolling compactor, which performs the actual …

Studies Of Direct Solar Irradiance And Aerosol Optical Depth Using An Mfrsr And A Microtop Sunphotometer In The El Paso-Juarez Airshed, Arjun Aryal

Open Access Theses & Dissertations

The study of Solar Irradiance and Aerosol Optical Depth (AOD) plays an important role in understanding the regional and global climate distribution, and is also important in air pollution studies. In this work an MFRSR (Multi-Filter Rotating Shadowband Radiometer) and a Portable Microtop Sunphotometer were used to measure irradiances and to obtain optical depth values for the El Paso-Juarez Airshed. The Langley method applied on the MFRSR irradiance data was used to calculate the AOD values. The spatial distribution of AOD for this region was obtained using a Microtop Sunphotometer. The graphs were generated using GIS Shapefiles. In addition, the …

Studies Of Air Pollutants And Their Impact On Respiratory And Cardiovascular Diseases In The El Paso Del Norte Region With Emphasis On Mobile Emissions, Juan Gustavo Arias Ugarte

Open Access Theses & Dissertations

Air pollution may cause different diseases, such as cardiovascular and lung diseases. Traffic is a major source of mobile emissions causing air pollution. Exhaust emissions from mobile sources (Emissions of Carbon Monoxide, Nitrogen Oxides and Hydrocarbons) and Non-exhaust (Brake and Tire) are complex mixtures of gases and dust, including a large number of ultrafine particles, especially in areas with high traffic density. Recent studies have shown high rates of morbidity and mortality in people exposed to these types of emissions because the fine and ultrafine particles can be transported from the respiratory airways to the organs, thus contributing to increase …

Computational Methods For Prediction And Classification Of G Protein-Coupled Receptors, Khodeza Begum

Open Access Theses & Dissertations

G protein-coupled receptors (GPCRs) constitute the largest group of membrane receptor proteins in eukaryotes. Due to their significant roles in many physiological processes such as vision, smell, and inflammation, GPCRs are the targets of many prescribed drugs. However, the functional and structural diversity of GPCRs has kept their prediction and classification based on amino acid sequence data as a challenging bioinformatics problem. As existing computational methods to predict and classify GPCRs are focused on mammalian (mostly human) data, the ultimate goal of our project is to establish an ensemble approach and implement a web-based software that can be used reliably …
