History of the Online Master of Engineering Management Program at Rowan University

This paper describes in detail the planning, development, and growth of a new online engineering management program. Planning began for the Master of Engineering Management (MEM) Program at Rowan University in January 2007 with a comprehensive review of 41 engineering management programs nationwide. The goal of this review was to determine the best practices regarding engineering management courses nationwide and the key courses required for an effective engineering management program. In Spring 2007, the proposal for the new MEM program was submitted to the University Senate at Rowan University for university review and approval and to the Academic Issues Committee of the New Jersey President’s Council for state review and approval. The MEM program was approved by the university and the state in Fall 2007 and the first courses in the MEM program were taught as hybrid courses beginning in Fall 2007. Conversion to 100% online courses was completed by Fall 2008. All courses are now offered fully online in an accelerated 8-week format. The program offers two courses per semester with a total of six courses per year. Graduation requirements call for students to complete 10 three-credit courses. Courses are scheduled such that students can complete their degree requirements in five consecutive semesters. Courses are structured such that students can begin the 10-course sequence at any point. To date, the program has admitted 142 students and graduated 79

Employees’ Financial Insecurity and Health: The Underlying Role of Stress and Work–Family Conflict Appraisals

Data from two longitudinal samples were utilized to elucidate underlying mechanisms of the well‐established relationship between financial insecurity and health outcomes, stemming from the theoretical rationale of conservation of resources and cognitive appraisal theories. Study 1 (n = 80) consisted of low‐wage food manufacturing employees working full time, while Study 2 (n = 331) was consisted of a larger, heterogeneous sample of full‐time workers representing multiple occupations. Respondents were surveyed on financial insecurity, work‐to‐family conflict (WFC), stress, and health outcomes at two time periods, 3 months apart. Results across our studies provided support for the direct effects of financial insecurity on WFC and stress. In addition, appraisals of WFC and stress serve as significant mediators of the relationship between financial insecurity and health outcomes, including a significant overall lagged effect across time, and perceived stress accounting for the largest proportion of variance in the lagged relationship among Time 1 financial insecurity and Time 2 health outcomes. Besides support for conservation of resources and cognitive appraisal theories, practically, our studies suggest that workplace initiatives to reduce financial insecurity could positively influence employees’ work–family, stress, and health experiences

Family Supportive Supervision Around the Globe

Family-supportive supervision (FSS) refers to the degree to which employees perceive their immediate supervisors as exhibiting attitudes and behaviors that are supportive of their family role demands (Hammer, Kossek, Zimmerman, & Daniels, 2007; Kossek, Pichler, Bodner & Hammer, 2011: Thomas & Ganster, 1995). A growing body of research suggests that leaders\u27 and supervisors\u27 social support of employees\u27 needs to jointly carry out work and family demands is important for general health and job attitudes, such as satisfaction, work-family conflict, commitment, and intention to turn over (Hammer, Kossek, Anger, Bodner, & Zimmerman, 2009; Kossek et al., 2011). Thus, employee perceptions of FSS are critical to individual well-being and productivity (Hammer, Kossek, Yragui, Bodner, & Hansen, 2009). [excerpt

Factors Affecting Anterior Knee Pain in Post-ACLR Comparing Patellar Tendon and Hamstring Tendon Autografts

Anterior cruciate ligament (ACL) injuries are frequent athletic and non-athletic injuries that impact a person\u27s functional and athletic capability. ACL injuries generally require surgical reconstruction. The most popular graft types include patellar tendon (PT) and hamstring tendon (HT) autografts. PT autografts have been blamed for chronic anterior knee pain (AKP) and extensor mechanism deficits. This study compared the PT and HT autografts and their impact on AKP in subjects who underwent anterior cruciate ligament reconstruction (ACLR). Data were gathered from existing patient data from rehabilitation therapy records. Additional factors were also analyzed to determine the effect on post-ACLR pain. Post-treatment pain ratings measured by the Numerical Pain Rating Scale (NPRS) were recorded for the patient\u27s first six weeks of therapy visits. A lack of descriptive documentation did not allow for specific pain location. Neither PT nor HT autografts had a significant effect on post-ACLR pain ratings. Rehabilitation type, age, and time from surgery to initial rehabilitation visit were found to have significant effects on pain ratings. This study indicated that multiple variables can affect pain post-ACLR and future studies should focus on additional factors affecting ACLR patients

Infrastructure Education Using the Impacts of Extreme Storms as Case Studies

Our university will begin offering a freshman level course titled “Introduction to Infrastructure” in Spring 2015. A common complaint from students over the years has been that they do not have a good understanding of what civil and environmental engineering is, and what civil engineers do. One of the goals of this course is to provide students with an early exposure to the practice of civil engineering and its importance to society. Our hope is that this will provide freshman with a solid context within which to continue their studies and motivate them to continue in the program. To this end, the primary goal of the course is to introduce freshmen civil and environmental engineers to civil infrastructure. Additionally, given the current state of infrastructure in the United States, the development of this course is of particular importance to the education and development of future engineers Our course will be a 2-credit lecture course consisting of two 75-minute periods per week of about 40 students per section. It will include sections on structural systems, foundations,transportation systems, water and environmental systems, as well as a general overview of the state of infrastructure in the US, along with other topics discussed in this report. Throughout the course, we will emphasize how the quality of infrastructure directly affects the economy and security of the US, and that the next generation of civil and environmental engineers needs to be more skilled and more able to design and create sustainable infrastructure. A significant emphasis will be placed on the impacts of extreme storms on water infrastructure and the impacts of storm surge and flooding on other infrastructure. We believe the emphasis on the impacts of extreme events on civil infrastructure, and water’s impacts on civil infrastructure in general, will provide a strong point of interest with students. It is likely this interest will be even greater at our university because a majority of our students were either directly or indirectly affected by a recent extreme storm event. Additionally, as the impacts of climate change have become measurable and as climate change projections suggest increased frequency and intensity of extreme events, the need to account for climate change in design for infrastructure is becoming more clearly recognized. A fact that is vital to increase reliability and decrease the nation’s risk and vulnerability to the failure of infrastructure in the future. Finally, we are hoping that the emphasis on extreme storms will help us highlight the connection of all civil infrastructure by providing students with a unifying context

WiscSort: External Sorting For Byte-Addressable Storage

We present WiscSort, a new approach to high-performance concurrent sorting for existing and future byte-addressable storage (BAS) devices. WiscSort carefully reduces writes, exploits random reads by splitting keys and values during sorting, and performs interference-aware scheduling with thread pool sizing to avoid I/O bandwidth degradation. We introduce the BRAID model which encompasses the unique characteristics of BAS devices. Many state-of-the-art sorting systems do not comply with the BRAID model and deliver sub-optimal performance, whereas WiscSort demonstrates the effectiveness of complying with BRAID. We show that WiscSort is 2-7x faster than competing approaches on a standard sort benchmark. We evaluate the effectiveness of key-value separation on different key-value sizes and compare our concurrency optimizations with various other concurrency models. Finally, we emulate generic BAS devices and show how our techniques perform well with various combinations of hardware properties

Total Dose Effects on Single Event Transients in Linear Bipolar Systems

Single Event Transients (SETs) originating in linear bipolar integrated circuits are known to undermine the reliability of electronic systems operating in the radiation environment of space. Ionizing particle radiation produces a variety of SETs in linear bipolar circuits. The extent to which these SETs threaten system reliability depends on both their shapes (amplitude and width) and their threshold energies. In general, SETs with large amplitudes and widths are the most likely to propagate from a bipolar circuit's output through a subsystem. The danger these SET pose is that, if they become latched in a follow-on circuit, they could cause an erroneous system response. Long-term exposure of linear bipolar circuits to particle radiation produces total ionizing dose (TID) and/or displacement damage dose (DDD) effects that are characterized by a gradual degradation in some of the circuit's electrical parameters. For example, an operational amplifier's gain-bandwidth product is reduced by exposure to ionizing radiation, and it is this reduction that contributes to the distortion of the SET shapes. In this paper, we compare SETs produced in a pristine LM124 operational amplifier with those produced in one exposed to ionizing radiation for three different operating configurations - voltage follower (VF), inverter with gain (IWG), and non-inverter with gain (NIWG). Each configuration produces a unique set of transient shapes that change following exposure to ionizing radiation. An important finding is that the changes depend on operating configuration; some SETs decrease in amplitude, some remain relatively unchanged, some become narrower and some become broader
