Analysis Of Asynchronous Supplemental Course Modules In Statistical Process Control, Matthew E. Harvey, John R. Haughery, Sai K. Ramaswamy

Sai Ramaswamy

Many engineering and technology departments at the collegiate level have developed extensive online and hybrid (face-to-face and online) course offerings (Bourne, Harris, & Mayadas, 2005). These courses may meet several goals such as increasing access, reducing university costs, providing schedule flexibility, and increasing curriculum offerings. An additional opportunity for computer-based learning is to increase student success by offering asynchronous learning modules to extend content beyond traditional lectures.

A Brief Review On Leading Big Data Models, Sugam Sharma, Udoyara S. Tim, Johnny S. Wong, Shashi Gadia, Subhash Sharma

Sugam Sharma

Today, science is passing through an era of transformation, where the inundation of data, dubbed data deluge is influencing the decision making process. The science is driven by the data and is being termed as data science. In this internet age, the volume of the data has grown up to petabytes, and this large, complex, structured or unstructured, and heterogeneous data in the form of “Big Data” has gained significant attention. The rapid pace of data growth through various disparate sources, especially social media such as Facebook, has seriously challenged the data analytic capabilities of traditional relational databases. The velocity …

Contextual Motivation In Physical Activity By Means Of Association Rule Mining, Sugam Sharma, Udoyara Sunday Tim, Marinelle Payton, Hari Cohly, Shashi Gadia, Johnny Wong, Sudharshanam Karakala

Sugam Sharma

The primary thrust of this work is to demonstrate the applicability of association rule mining in public health domain, focusing on physical activity and exercising. In this paper, the concept of association rule mining is shown assisting to promote the physical exercise as regular human activity. Specifically, similar to the prototypical example of association rule mining, market basket analysis, our proposed novel approach considers two events – exercise (sporadic) and sleep (regular) as the two items of the frequent set; and associating the former, exercise event, with latter, the daily occurring activity sleep at night, helps strengthening the frequency of …

N-Management And Crop Rotation Effects On Yield And Residual Soil Nitrate Levels, A. Bakhsh, R. S. Kanwar, D. L. Karlen, C. A. Cambardella, T. B. Bailey, T. B. Moorman, T. S. Colvin

Douglas L Karlen

Swine production facilities are becoming more concentrated in Iowa, and public is concerned about the impact of using swine manure for crop production on soil and water quality. This field study was conducted from 1996 to 1998 to compare the effects of liquid swine manure and urea ammonium nitrate (UAN) application on crop yield and residual soil nitrate for continuous corn (Zea mays L.) and corn-soybean (Glycine max (L.) Merr.) rotation systems. Six N management treatments were replicated three times in a randomized complete block design at Iowa State University's northeastern research center in Nashua, Iowa. Injected UAN provided 135 …

The Engineering Admissions Partnership Program: A Navigation Strategy For Community College Students Seeking A Pathway Into Engineering, Marcia R. Laugerman, Mack C. Shelley, Steven K. Mickelson, Diane T. Rover

Diane Rover

This paper presents the evaluation of a program designed to improve transfer outcomes for community college students pursuing an engineering degree. The program, the Engineering Admissions Partnership Program (E-APP), was designed to improve the navigational success of community college transfer students through connections to the university. These connections include coordinated academic advising, peer-mentoring, campus visits, and online social and professional networks. The objective of the study is to determine the efficacy of the E-APP and its interventions, which will be measured by increased participation rates and increased university retention rates for E-APP participants. Outcome data for the students are analyzed …

An Investigation Of Quality Climate And Its Association With Implementation Of Quality Management System, Sai K. Ramaswamy, Gretchen A. Mosher

Sai Ramaswamy

Quality management and continuous improvement are paramount for businesses to survive and thrive in today’s competitive landscape (Goetsch & Davis, 2003; Abdullah et al., 2009). One effective approach to operationalize quality processes and continuous improvement goals is a formalized quality management system (Khanna et al., 2010; Mosher et al., 2013). Quality management systems are embodiments of the organization’s policies, procedures, plans, resources, processes and delegation of responsibility and authority designed to achieve customer satisfaction within the boundaries of organizational objectives (Goetsch & Davis, 2003). While these systems are being used extensively across many industries, the ideas are relatively new to …

Approaching Safety Through Quality: Factors Influencing College Student Perceptions, Sai K. Ramaswamy, Gretchen A. Mosher

Sai Ramaswamy

Quality management practices have been identified by previous literature as a factor that could potentially reduce the level of safety incidents and hazards in agricultural work environments. The present study used multivariate analysis to examine the effect of independent variables such as quality and safety awareness, work experience, safety and quality management experience, and the perceived importance of safety and quality on the role of quality management practices as a mitigating factor for safety hazards and incidents in agriculture. Variables were measured on a five-point scale using a survey questionnaire. Data were collected from approximately 900 undergraduates enrolled in the …

Perceptions Of Agricultural College Students On The Relationship Between Quality And Safety In Agricultural Work Environments, Sai K. Ramaswamy, Gretchen A. Mosher

Sai Ramaswamy

Agriculture is a high-hazard industry that employs a large number of young workers below the age of 25. Recent studies have documented a strong positive correlation between quality management in agriculture and occupational safety as perceived by agricultural workers. Younger workers have been found to be at higher risk for occupational injuries and fatalities in agriculture. Furthermore, college students in agriculture have minimal exposure to safety and quality management principles in their coursework and thus may not be aware that the two concepts are associated. Little research has studied how young workers perceive the relationship between safety and quality and …

Maximum Soil Organic Carbon Storage In Midwest U.S. Cropping Systems When Crops Are Optimally Nitrogen-Fertilized, Hanna J. Poffenbarger, Daniel W. Barker, Matthew J. Helmers, Fernando E. Miguez, Daniel C. Olk, John E. Sawyer, Johan Six, Michael J. Castellano

John E. Sawyer

Nitrogen fertilization is critical to optimize short-term crop yield, but its long-term effect on soil organic C (SOC) is uncertain. Here, we clarify the impact of N fertilization on SOC in typical maize-based (Zea mays L.) Midwest U.S. cropping systems by accounting for site-to-site variability in maize yield response to N fertilization. Within continuous maize and maize-soybean [Glycine max (L.) Merr.] systems at four Iowa locations, we evaluated changes in surface SOC over 14 to 16 years across a range of N fertilizer rates empirically determined to be insufficient, optimum, or excessive for maximum maize yield. Soil organic C balances …
