Effective Teaching In Higher Education For The 21st Century Adult Learner, Denise Murchison Payton

Walden Dissertations and Doctoral Studies

Abstract

As college populations are becoming increasingly diverse, institutions must find ways to meet the needs of their nontraditional students. Nontraditional adult learners are self-directed, ready to learn, and are internally motivated to engage in problem-centered learning. The purpose of this study was to expand and refine an active learning seminar in a higher education setting to improve the quality of teaching, student engagement, and retention rates. The site of the study was a Historically Black College and University (HBCU) in which adult students over 25 constituted 49% of the population. The faculty members at this site predominantly employed traditional …

Self-Efficacy, Locus Of Control, And Parental Involvement On Students' Academic Achievement, Helen Faye Clay-Spotser

Walden Dissertations and Doctoral Studies

Minority students are lagging behind their non-minority peers in academic achievement. Compounding this problem is the lack of research on minority students' perceptions on their connections to school, their feelings of autonomy, and their relationship with their parents. These variables are important considerations in this problem, as Ryan and Deci's self-determination theory suggests a strong relationship between student performance in school and students' perceptions of their intrinsic and extrinsic motivators. To address that gap, this cross-sectional, quantitative research study examined the relationship between minority high school students' perceived self-efficacy, locus of control, and parents' educational involvement on their self-reported academic …

Personality Traits Associated With Environmental Concern, Tara Rae Wuertz

Walden Dissertations and Doctoral Studies

The 5 factor model of personality, including the traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism, is a well-established theoretical model for describing how personality is structured. Hirsh (2010) demonstrated the big 5 personality traits, excluding extraversion, were correlated with pro-environmental attitudes. The purpose of this quantitative study was to replicate previous findings, and discover if there was a correlation with a person's pro-environmental behaviors and the big 5 personality traits. A total of 100 participants from an online participant pool completed a survey, which included the Environmental Concern Scale to measure concern and attitudes about the environment, and the …

Learned Helplessness And Depression: Comparison Of Skilled Nursing And Assisted Living Facilities, Paul Lynn Susic

Walden Dissertations and Doctoral Studies

Research with geriatric populations suggests high levels of clinical depression and greater financial and psychological costs of treatment in long-term care facilities with more restrictive care. Research on learned helplessness, a construct separate from depression, suggests learned helplessness and perceived control are useful theories for the study of elder depression, but the relationship between depression and learned helplessness in this population is not clear. This cross-sectional quantitative study examined the relationship between depression and learned helplessness by comparing residents over age 65 in less restrictive assisted living (n =42) versus those in more restrictive skilled nursing facilities (n =63). Data …

A Mindfulness-Based Stress Reduction Psychoeducational Program In Postpartum Support Groups, Marina Pesserl

Walden Dissertations and Doctoral Studies

Postpartum Depression (PPD) affects 15% of women after childbirth. Its etiology includes psychoneuroimmunologic factors with long-lasting postpartum stressors that lead to allostatic overload. Using mindfulness-based stress reduction (MBSR) for PPD has not yet been studied. Addressing this literature gap, the potential benefits of including an 8-week MBSR component based on Beck's theory of PPD at support groups were examined in this phenomenological study based on a sample of 10 women and 2 group facilitators. Purposes of the study included describing the experience of PPD and the MBSR program, identifying the stage of behavioral change of the participants, and describing the …

Centering The Teenage "Siren": Adolescent Workers, Sexual Harassment, And The Legal Construction Of Race And Gender, Anastasia M. Boles

Law Faculty Scholarship

Recent scholarship and media attention has focused on the prevalence of sexually harassing behavior directed at working teenagers, and the emergence of sexual harassment lawsuits by these minors against their employers. Although many of the legal issues concerning workplace sexual harassment and adult workers (and the various state and federal jurisprudence prohibiting it) have been widely discussed, there is surprisingly little discourse, research, and precedent addressing the problem of workplace sexual harassment and teen workers.

Currently, most sexual harassment cases brought by adolescent workers are litigated using the doctrinal framework for adult workers. Only the Seventh Circuit has developed an …

Dartmouth Scholarship

There is an increasing demand in higher education institutions for training in complex environmental problems. Such training requires a careful mix of conventional methods and innovative solutions, a task not always easy to accomplish. In this paper we review literature on this theme, highlight relevant advances in the pedagogical literature, and report on some examples resulting from our recent efforts to teach complex environmental issues. The examples range from full credit courses in sustainable development and research methods to project-based and in-class activity units. A consensus from the literature is that lectures are not sufficient to fully engage students in …

Beyond The Excluded Volume Effects: Mechanistic Complexity Of The Crowded Milieu, Irina M. Kuznetsova, Boris Y. Zaslavsky, Leonid Breydo, Konstantin K. Turoverov, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Macromolecular crowding is known to affect protein folding, binding of small molecules, interaction with nucleic acids, enzymatic activity, protein-protein interactions, and protein aggregation. Although for a long time it was believed that the major mechanism of the action of crowded environments on structure, folding, thermodynamics, and function of a protein can be described in terms of the excluded volume effects, it is getting clear now that other factors originating from the presence of high concentrations of “inert” macromolecules in crowded solution should definitely be taken into account to draw a more complete picture of a protein in a crowded milieu. …

Structure And Stability Of Recombinant Bovine Odorant-Binding Protein: Ii. Unfolding Of The Monomeric Forms, Olga V. Stepanenko, Denis O. Roginskii, Olesya V. Stepanenko, Irina M. Kuznetsova, Vladimir N. Uversky, Konstantin K. Turoverov

Molecular Medicine Faculty Publications

In a family of monomeric odorant-binding proteins (OBPs), bovine OBP (bOBP), that lacks conserved disulfide bond found in other OBPs, occupies unique niche because of its ability to form domain-swapped dimers. In this study, we analyzed conformational stabilities of the recombinant bOBP and its monomeric variants, the bOBP-Gly121+ mutant containing an additional glycine residue after the residue 121 of the bOBP, and the GCC-bOBP mutant obtained from the bOBP-Gly121+ form by introduction of the Trp64Cys/His155Cys double mutation to restore the canonical disulfide bond. We also analyzed the effect of the natural ligand binding on the conformational stabilities of these bOBP …

Intrinsically Disordered Caldesmon Binds Calmodulin Via The “Buttons On A String” Mechanism, Sergei E. Permyakov, Eugene A. Permyakov, Vladimir N. Uversky

Molecular Medicine Faculty Publications

We show here that chicken gizzard caldesmon (CaD) and its C-terminal domain (residues 636–771, CaD136) are intrinsically disordered proteins. The computational and experimental analyses of the wild type CaD136 and series of its single tryptophan mutants (W674A, W707A, and W737A) and a double tryptophan mutant (W674A/W707A) suggested that although the interaction of CaD136 with calmodulin (CaM) can be driven by the non-specific electrostatic attraction between these oppositely charged molecules, the specificity of CaD136-CaM binding is likely to be determined by the specific packing of important CaD136 tryptophan residues at the CaD136-CaM interface. It is suggested that this interaction can be …

Fendiline Inhibits Proliferation And Invasion Of Pancreatic Cancer Cells By Interfering With Adam10 Activation And Β-Catenin Signaling, Neha Woods, Jose Trevino, Domenico Coppola, Srikumar Chellappan, Shengyu Yang, Jaya Padmanabhan

Molecular Medicine Faculty Publications

ADAM10 (A Disintegrin and Metalloprotease Domain 10) affects the pathophysiology of various cancers, and we had shown that inhibition of ADAM10 sensitizes pancreatic cancer cells to gemcitabine. ADAM10 is activated in response to calcium influx, and here we examined if calcium channel blockers (CCB) would impede ADAM10 activation and affect biology of pancreatic cancer cells. We find that the CCB, fendiline, significantly reduces proliferation, migration, invasion, and anchorage independent growth of pancreatic cancer cells. This was associated with ADAM10 inhibition and its localization at the actin-rich membrane protrusions. Further, fendiline-treated cells formed cadherin-catenin positive tight adherens junctions and elicited defective …

Structure And Stability Of Recombinant Bovine Odorant-Binding Protein: I. Design And Analysis Of Monomeric Mutants, Olga V. Stepanenko, Denis O. Roginskii, Olesya V. Stepanenko, Irina M. Kuznetsova, Vladimir N. Uversky, Konstantin K. Turoverov

Molecular Medicine Faculty Publications

Bovine odorant-binding protein (bOBP) differs from other lipocalins by lacking the conserved disulfide bond and being able to form the domain-swapped dimers. To identify structural features responsible for the formation of the bOBP unique dimeric structure and to understand the role of the domain swapping on maintaining the native structure of the protein, structural properties of the recombinant wild type bOBP and its mutant that cannot dimerize via the domain swapping were analyzed. We also looked at the effect of the disulfide bond by designing a monomeric bOBPs with restored disulfide bond which is conserved in other lipocalins. Finally, to …

“In-Plant” Nmr: Analysis Of The Intact Plant Vesicularia Dubyana By High Resolution Nmr Spectroscopy, Viktor P. Kutyshenko, Peter Beskaravayny, Vladimir N. Uversky

Molecular Medicine Faculty Publications

We present here the concept of “in-plant” NMR and show that high-resolution NMR spectroscopy is suitable for the analysis of intact plants and can be used to follow the changes in the intraorganismal molecular composition over long time periods. The NMR-based analysis of the effect of different concentrations of heavy water on the aquatic plant Vesicularia dubyana revealed that due to the presence of specific adaptive mechanisms this plant can sustain the presence of up to 85% of D₂O. However, it dies in 100% heavy water.

Loss Of Multidrug Resistance-Associated Protein 1 (Mrp1/Abcc1) Potentiates Doxorubicin-Induced Cardiotoxicity In Mice, Wei Zhang

Theses and Dissertations--Toxicology and Cancer Biology

Doxorubicin (DOX) is a broad-spectrum and effective chemotherapeutic agent, but its use in oncologic practice is limited by dose-dependent cumulative cardiotoxicity. DOX-induced cardiotoxicity is in large part due to its ability to cause oxidative stress. Multidrug resistance associated protein 1 (MRP1/ABCC1) is a member of the ATP-binding cassette (ABC) transporter superfamily. By effluxing a wide variety of endogenous and exogenous substrates, Mrp1 plays important physiological roles in multiple tissues and also protects normal tissues against toxicants. However, the role of MRP1 in heart is largely unknown.

The role of Mrp1 in DOX-induced cardiotoxicity was investigated in Mrp1 null (Mrp1-/-) and …

Analysis Of Humira, Electro-Acupuncture, And Pulsatile Dry Cupping On Reducing Joint Inflammation In Patients With Rheumatoid Arthritis, Natalie Noll

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Humira, an anti-TNF drug aimed at decreasing inflammation in Rheumatoid Arthritis patients, can cause skin diseases from rashes to skin cancer. Humira works by blocking the chemical receptor RANKL which inhibits the production of osteoclasts. Osteoclasts are cells that attack and eat bone and cartilage therefore an inhibitory mechanism would cause inflammation.. By analyzing Humira’s effect on the human body, Humira can be compared to other treatments such as electro-acupuncture and pulsatile dry cupping to determine the viability of these alternative treatment methods in regards to their abilities to decrease inflammation in Rheumatoid Arthritis patients through blocking RANKL. An analysis …

Analysis And Suppression Of Engine Hood Vibrations Under Random Road Excitations, Hooman Farrokhzadeh

Wayne State University Theses

Vehicle designs and developments must meet safety legislations along with market demands. Safety regulations are mainly concerned with how a vehicle body performs in crashes, during which pedestrian collision is the one of the most important issues. When a vehicle strikes a pedestrian, its engine hood will most likely hit the head of the pedestrian, causing serious injuries. To reduce the severity of the injuries, along with market demands to improve vehicle fuel economy and performance, engineers have considered the design solution of reduction of the vehicle hood thickness (and hence its weight) and the use of advanced light materials. …
