Journal of Human Performance in Extreme Environments

We used a field excursion to the West Clearwater Lake Impact structure as an opportunity to test factors that contribute to the decisions a remote field team (for example, astronauts conducting extravehicular activities (EVA) on planetary surfaces) makes while collecting samples for return to Earth. We found that detailed background on the analytical purpose of the samples, provided to the field team, enables them to identify and collect samples that meet specific analytical objectives. However, such samples are not always identifiable during field reconnaissance activities, and may only be recognized after outcrop characterization and interpretation by crew and/or science ...

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu Dec 2015

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu

Keke Chen

This paper presents a random rotation perturbation approach for privacy preserving data classification. Concretely, we identify the importance of classification-specific information with respect to the loss of information factor, and present a random rotation perturbation framework for privacy preserving data classification. Our approach has two unique characteristics. First, we identify that many classification models utilize the geometric properties of datasets, which can be preserved by geometric rotation. We prove that the three types of classifiers will deliver the same performance over the rotation perturbed dataset as over the original dataset. Second, we propose a multi-column privacy model to address the ...

Management Strategy Evaluation For The Atlantic Surfclam, Spisula Solidissima, Using A Fisheries Economics Model, Kelsey M. Kuykendall Dec 2015

Management Strategy Evaluation For The Atlantic Surfclam, Spisula Solidissima, Using A Fisheries Economics Model, Kelsey M. Kuykendall

Master's Theses

The Atlantic surfclam, Spisula solidissima, is an economically valuable bivalve harvested along the northeastern United States. The surfclam’s range has contracted and the center of the stock’s distribution has shifted north driven by warmer bottom water temperatures. Declining landings per unit effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. The objective of this project is to perform a management strategy evaluation (MSE) for Spisula solidissima. The terminal goal is to identify a preferred management option that promotes enhanced surfclam productivity in the ...

Evaluation Of Conservation Practices Through Simulation Modeling And Tool Development, Gurdeep Singh

Theses and Dissertations

For the first objective, predicted impacts of selected Mississippi River Basin Initiative (MRBI) conservation practices (CPs) on sediment and nutrient loss were assessed. The study area was L’Anguille River Watershed (LRW), a priority focus watershed of the MRBI program and the simulated CPs were filter strip, critical area planting, grade stabilization structure, irrigation land leveling, irrigation pipeline, irrigation water management, and nutrient management. The Soil and Water Assessment Tool (SWAT) model was calibrated (1998 – 2005) and validated (2006 – 2012) for flow, sediment, total phosphorus (TP), and nitrate-nitrogen (NO3-N) at the Colt site (503 sq. km. drainage area) and for ...


Intent Classification Of Short-Text On Social Media, Hemant Purohit, Guozhu Dong, Valerie L. Shalin, Krishnaprasad Thirunarayan, Amit P. Sheth Dec 2015

Intent Classification Of Short-Text On Social Media, Hemant Purohit, Guozhu Dong, Valerie L. Shalin, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

Social media platforms facilitate the emergence of citizen communities that discuss real-world events. Their content reflects a variety of intent ranging from social good (e.g., volunteering to help) to commercial interest (e.g., criticizing product features). Hence, mining intent from social data can aid in filtering social media to support organizations, such as an emergency management unit for resource planning. However, effective intent mining is inherently challenging due to ambiguity in interpretation, and sparsity of relevant behaviors in social data. In this paper, we address the problem of multiclass classification of intent with a use-case of social data generated ...


“Personas” To Support Development Of Cyberinfrastructure For Scientific Data Sharing, Kevin Crowston Nov 2015

“Personas” To Support Development Of Cyberinfrastructure For Scientific Data Sharing, Kevin Crowston

DataONE Sociocultural and Usability & Assessment Working Groups

Objective: To ensure that cyberinfrastructure for sharing scientific data is useful, system developers need to understand what scientists and other intended users do as well as the attitudes and beliefs that shape their behaviours. This paper introduces personas — detailed descriptions of an “archetypical user of a system” — as an approach for capturing and sharing knowledge about potential system users.

Setting: Personas were developed to support development of the ‘DataONE’ (Data Observation Network for Earth) project, which has developed and deployed a sustainable long-term data preservation and access network to ensure the preservation and access to multi-scale, multi-discipline, and multi-national environmental ...


Loyalty Cards And The Problem Of Captcha.Pdf, David M. Cook Nov 2015

Loyalty Cards And The Problem Of Captcha.Pdf, David M. Cook

Dr. David M Cook


Information Security often works in antipathy to access and useability in communities of older citizens. Whilst security features are required to prevent the disclosure of information, some security tools have a deleterious effect upon users, resulting in insecure practices. Security becomes unfit for purpose where users prefer to abandon applications and online benefits in favour of non-digital authentication and verification requirements. For some, the ability to read letters and symbols from a distorted image is a decidedly more difficult task than for others, and the resulting level of security from CAPTCHA tests is not consistent from person to person. This ...

Users' Perspective On The Relationship Between Internal Controls And Key Constructs, Santosh Mutnuru Nov 2015

Users' Perspective On The Relationship Between Internal Controls And Key Constructs, Santosh Mutnuru

Master's Theses and Doctoral Dissertations

This study sought to understand a user's perspective on the level of influence that internal controls had on the levels of trust, employee engagement, employee performance, and organization performance. The relationship between the level of implementation of internal controls with the level of trust that employees have for their employer, employee engagement, employee performance, and organization performance has not been adequately explored. The study was conducted on users who worked in organizations that implemented Committee of Sponsoring Organizations of the Treadway Commission (COSO) internal controls, and these organizations strictly maintain all of their information in digital format. About nine ...


Understanding How Organizations Operate Their It Capacity-Management Processes, Joseph Frederick Bauer Nov 2015

Understanding How Organizations Operate Their It Capacity-Management Processes, Joseph Frederick Bauer

Master's Theses and Doctoral Dissertations

There is a lack of understanding of how organizations operate their IT capacity-management processes. Within the body of literature on IT capacity-management there is an abundance of advice for organizations on how to set up or run the processes for IT capacity-management, but very little in the way of describing the processes as performed and operated in organizations out in the field. Using qualitative methods this research sought to gain an understanding of how organizations are operating their IT capacity-management processes in the field. A dozen subjects from 10 organizations were interviewed and the data were analyzed with a grounded ...


Blurring The Lines: The Overlapping Interests Of High Altitude Unmanned Aircraft, Commercial Space, And Aviation Policy, Ruth E. Stilwell Nov 2015

Blurring The Lines: The Overlapping Interests Of High Altitude Unmanned Aircraft, Commercial Space, And Aviation Policy, Ruth E. Stilwell

Space Traffic Management Conference

The commercialization of space operations, coupled with the rapid development in unmanned aircraft systems creates a new policy dynamic between otherwise disparate industries. Existing structures do not adequately address issues of access, governance, and sovereignty across the distinct domains of air transport, space operations, and high altitude unmanned aircraft operations. Globally, aviation policy and space policy have evolved independently as distinct fields. High altitude unmanned aircraft are rapidly increasing utilization of airspace not previously occupied by civil aircraft or spacecraft, where regulation of both safety and access is sparse. Rather than consider operations in this airspace as a third category ...


Assessing Student Perceptions Of Indigenous Science Co-Educators, Interest In Stem, And Identity As A Scientist: A Pilot Study, Sarah Alkholy, Fidji Gendron, Tanya Dahms, Maria Pontes Ferreira Nov 2015

Assessing Student Perceptions Of Indigenous Science Co-Educators, Interest In Stem, And Identity As A Scientist: A Pilot Study, Sarah Alkholy, Fidji Gendron, Tanya Dahms, Maria Pontes Ferreira

Nutrition and Food Science Faculty Research Publications

Minorities are underrepresented in the science, technology, engineering, and mathematics (STEM) workforce, post-secondary STEM education, and show high academic attrition rates. Academic performance and retention improve when culturally relevant support is provided. The interface of Western science and Indigenous science provides an opportunity for bridging this divide. We hypothesized that there would be regional (U.S.A. vs. Canada) differences amongst post-secondary students regarding these variables: perceptions of traditional Elders as STEM co-educators; interest in STEM; and self-identity as a scientist. We conducted a short-term longitudinal pilot study of an interdisciplinary, multi-institutional, and cross-cultural STEM course in the spring of ...

Understanding The Relationship Between Technical And Managerial Factors And Product Innovation At A Tier 1 Engine Component Supplier, Carmo Ribeiro Oct 2015

Understanding The Relationship Between Technical And Managerial Factors And Product Innovation At A Tier 1 Engine Component Supplier, Carmo Ribeiro

Master's Theses and Doctoral Dissertations

This study provided an assessment of the technical and managerial factors on the development of successful innovative internal combustion engine (ICE) components at a XYZ Tier 1 supplier firm. Further, factors related to regulations, component application, and customer integration were identified and complement the study.

A deficiency has been identified in the literature in that most studies concentrate on inter-firm innovation from the customer’s perspective within the supply-chain relationship. While suppliers have increasingly become a source of innovation, very little is known about specific ways in which innovation occurs at Tier 1 suppliers. The mechanisms by which innovative ideas ...


Framing The Mh17 Disaster – More Heat Than Light?, Simon A. Bennett Oct 2015

Framing The Mh17 Disaster – More Heat Than Light?, Simon A. Bennett

International Journal of Aviation, Aeronautics, and Aerospace

Despite the reductionist analyses produced by politicians and the Fourth Estate, the loss of Malaysia Airlines Flight MH17 was a systems accident – a product of the interactions between the actants that compose the commercial aviation system network-space. As an antidote to reductionism’s ‘fundamental attribution error’, this paper presents a systems-thinking-informed analysis of the MH17 disaster. To this end it draws on Actor-Network Theory and the work of Reason, Toft, Dekker, Hollnagel and other systems-thinking advocates. Whether intentional or not, politicians’ reductionist analyses generated political capital. European Union and American finger-pointing distracted from aviation authorities’ and airlines’ ill-advised routing policies ...

Kno.e.sis Publications

Clinical documents are vital resources for radiologists to have a better understanding of patient history. The use of clinical documents can complement the often brief reasons for exams that are provided by physicians in order to perform more informed diagnoses. With the large number of study exams that radiologists have to perform on a daily basis, it becomes too time-consuming for radiologists to sift through each patient's clinical documents. It is therefore important to provide a capability that can present contextually relevant clinical documents, and at the same time satisfy the diverse information needs among radiologists from different specialties ...

Stochastic Modeling And Optimization Of Multi-Plant Capacity Planning Problem, Anoop Verma, Nagesh Shukla, S.K Tyagi, Nishikant Mishra Sep 2015

Stochastic Modeling And Optimization Of Multi-Plant Capacity Planning Problem, Anoop Verma, Nagesh Shukla, S.K Tyagi, Nishikant Mishra

Nagesh Shukla

n this paper the problem of capacity planning under risk from demand and price/cost uncertainty of the finished products is addressed. The deterministic model is extended into a two-stage stochastic model with fixed recourse by means of various expected levels of demand as random. A recourse penalty is also included in the objective for both shortage and surplus in the finished products. The model is analyzed to quantify the risk using Markowitz mean-variance model.
