Assessing undergraduate student involvement: a closer look at the African American pattern

The purpose of this study was to investigate the involvement patterns of selected African American undergraduate students and explore the reasoning as to why they choose to participate in certain groups and abstain from others. Data were collected through a three part survey with 60 Likert-type items used, and through a series of interviews. The population used was a convenience sample of 178 students at Rowan University\u27s main campus in Glassboro, NJ. Eight students of that sample were purposely selected to participate in interviews. Data analysis of the surveys showed positive relationships between students who worked with classmates outside of class and worked on projects during class. There were no disparities between gender and class rank when compared to importance and satisfaction of academic involvement. The results of the surveys showed that most of the selected students participated in intramural athletics and social clubs while abstaining from university publication and independent study. Data from the interviews revealed that students felt connected to one another in ethnic and multicultural clubs and organizations, though they believed there is a lack of options on campus to engage in activities with students from other races

GAP ANALYSIS OF DEPARTMENT OF DEFENSE PROGRAM MANAGEMENT COMPETENCY STANDARDS IN PREPARATION FOR THE SHIFT TO PORTFOLIO MANAGEMENT IN DEFENSE ACQUISITIONS

The purpose of this study is to perform a gap analysis on the existing Department of Defense (DOD) program management competency standards to determine if changes are required to fully adopt product portfolio management (PPM) strategies in defense acquisitions. We do this by comparing the current DOD standards to the Project Management Institute's Portfolio Management Professional certification standards. We ask where the gaps in the standards exist and where the standards align, and assign a Barrier to Implementation (BTI) score to each gap in the DOD standard. The study found that the DOD is on average 41% aligned with industry standards. In the higher weighted domains of Governance and Strategic Alignment, alignment percentages are significantly lower. The composite BTI score for the DOD is 1.45, indicating low to medium BTIs for most of the gaps. Results do not suggest that the DOD is incapable of conducting PPM, but rather that the current competency standards do not align with industry best practices. Defense acquisitions professionals should review our analysis and formulate Portfolio Management Career Field Functional Competencies to further professional standards, develop the necessary job skills and evaluation criteria, and further the process of achieving congressional mandates for portfolio management implementation.Outstanding ThesisMajor, United States Marine CorpsMajor, United States Marine CorpsMajor, United States Marine CorpsApproved for public release.

Coordination of trunk and foot acceleration during gait is affected by walking velocity and fall history in elderly adults

This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.Background: Falling is a significant concern for many elderly adults but identifying individuals at risk of falling is difficult, and it is not clear how elderly adults adapt to challenging walking. Aims: The aim of the current study was to determine the effects of walking at non-preferred speeds on the coordination between foot and trunk acceleration variability in healthy elderly adults with and without fall history compared to healthy young adults. Methods: Subjects walked on a treadmill at 80% to 120% of their preferred walking speed while trunk and foot accelerations were recorded with wireless inertial sensors. Variability of accelerations were measured by root mean square, range, sample entropy, and Lyapunov exponent. The gait stability index was calculated using each variability metric in the frontal and sagittal plane by taking the ratio of trunk acceleration variability divided by foot acceleration variability. Results: Healthy young adults demonstrated larger trunk accelerations relative to foot accelerations at faster walking speeds compared to elderly adults, but both young and elderly adults show similar adaption to their acceleration regularity. Between group differences showed that elderly adult fallers coordinate acceleration variability between the trunk and feet differently compared to elderly non-fallers and young adults. Discussion: The current results indicate that during gait, elderly fallers demonstrate more constrained, less adaptable trunk movement relative to their foot movement and this pattern is different compared to elderly non-fallers and healthy young. Conclusions: Coordination between trunk and foot acceleration variability plays an important role in maintaining stability during gait.NIH T32 HD057850Frontiers Pilot and Collaborative Studies Funding Program (UL1TR000001)School of Health Professions Pilot Research Gran

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) in a Patient with Diabetes: a primary care perspective

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a recurrent and progressive disease that causes proximal, symmetrical extremity weakness. The disease is diagnosed using clinical features, electrophysiologic testing, albumino-cytological disassociation in the cerebrospinal fluid, and sural nerve plexus biopsy. However, because of the low sensitivity of diagnostic criteria and other similar neuropathies, including diabetic polyneuropathy (DPN), accurate diagnosis is difficult. Differentiating between these diseases is especially important as CIDP’s changes are reversible and DPN’s are not. Making this differentiation allows for symptomatic improvement in a patient’s quality of life that would not be achieved otherwise. Early recognition and treatment, with modalities including corticosteroids, plasmapheresis, and IVIG, demonstrate improvement in a majority of patients. Primary care physicians (PCP) encounter patients with diabetes daily. It is important for PCPs to have a level of familiarity with CIDP to best care for those patients

Preventing Isolated Perioperative Reintubation: Who is at highest risk?

Objectives: 1. We aim to characterize IPR nationally through a retrospective review of the National Surgical Quality Improvement Program participant user file (NSQIP PUF). 2.Identify risk factors for IPR including analysis of procedure type and preoperative characteristics.https://jdc.jefferson.edu/patientsafetyposters/1041/thumbnail.jp

Dissecting a complex chemical stress: chemogenomic profiling of plant hydrolysates.

The efficient production of biofuels from cellulosic feedstocks will require the efficient fermentation of the sugars in hydrolyzed plant material. Unfortunately, plant hydrolysates also contain many compounds that inhibit microbial growth and fermentation. We used DNA-barcoded mutant libraries to identify genes that are important for hydrolysate tolerance in both Zymomonas mobilis (44 genes) and Saccharomyces cerevisiae (99 genes). Overexpression of a Z. mobilis tolerance gene of unknown function (ZMO1875) improved its specific ethanol productivity 2.4-fold in the presence of miscanthus hydrolysate. However, a mixture of 37 hydrolysate-derived inhibitors was not sufficient to explain the fitness profile of plant hydrolysate. To deconstruct the fitness profile of hydrolysate, we profiled the 37 inhibitors against a library of Z. mobilis mutants and we modeled fitness in hydrolysate as a mixture of fitness in its components. By examining outliers in this model, we identified methylglyoxal as a previously unknown component of hydrolysate. Our work provides a general strategy to dissect how microbes respond to a complex chemical stress and should enable further engineering of hydrolysate tolerance

The challenges of a public data release : behind the scenes of SDSS DR13

The Sloan Digitial Sky Surveys (SDSS) have been collecting imaging and spectoscopic data since 1998. These data as well as their derived data products are made publicly available through regular data releases, of which the 13th took place summer 2016. Although public data releases can be challenging to manage, they significantly increase the impact of a survey, both scientifically and educationally.Postprin
