Re-Imagining Student Achievement : The Egalitarian Failure Of The Carrot-Stick Model In K-12 Public Education, Michael Johnson Jan 2019

Re-Imagining Student Achievement : The Egalitarian Failure Of The Carrot-Stick Model In K-12 Public Education, Michael Johnson

Honors Theses

Achievementgaps between low-income and minority students and their counterparts are among the most pressing education policy issues today. Cash incentivization to students has gained momentum as a potential remedy to reduce disparities in studentachievementoutcomes. Grading incentive schemes function identically as objections to cash-incentives positioning both within the broader carrot-stick motivation model. Rather than eliminate the widely used grading scheme, however, I conclude that efforts should be redirected towards reducing the saliency of standardized evaluative benchmarks to which incentives are aimed as opposed to reforming the incentives themselves which I refer to as the Revisionary Proposal.

Less Is More: Beating The Market With Recurrent Reinforcement Learning, Louis Kurt Bernhard Steinmeister Jan 2019

Less Is More: Beating The Market With Recurrent Reinforcement Learning, Louis Kurt Bernhard Steinmeister

Masters Theses

"Multiple recurrent reinforcement learners were implemented to make trading decisions based on real and freely available macro-economic data. The learning algorithm and different reinforcement functions (the Differential Sharpe Ratio, Differential Downside Deviation Ratio and Returns) were revised and the performances were compared while transaction costs were taken into account. (This is important for practical implementations even though many publications ignore this consideration.) It was assumed that the traders make long-short decisions in the S&P500 with complementary 3-month treasury bill investments. Leveraged positions in the S&P500 were disallowed. Notably, the Differential Sharpe Ratio and the Differential Downside Deviation Ratio are risk …


Designing A Russian Idiom-Annotated Corpus, Katsiaryna Aharodnik, Anna Feldman, Jing Peng Jan 2019

Designing A Russian Idiom-Annotated Corpus, Katsiaryna Aharodnik, Anna Feldman, Jing Peng

Department of Linguistics Faculty Scholarship and Creative Works

This paper describes the development of an idiom-annotated corpus of Russian. The corpus is compiled from freely available resources online and contains texts of different genres. The idiom extraction, annotation procedure, and a pilot experiment using the new corpus are outlined in the paper. Considering the scarcity of publicly available Russian annotated corpora, the corpus is a much-needed resource that can be utilized for literary and linguistic studies, pedagogy as well as for various Natural Language Processing tasks.


Posttraumatic Stress And Parenting Behaviors: The Mediating Role Of Emotion Regulation, Shaina A. Kumar, Molly R. Franz, Rebecca L. Brock, David Dilillo Jan 2019

Posttraumatic Stress And Parenting Behaviors: The Mediating Role Of Emotion Regulation, Shaina A. Kumar, Molly R. Franz, Rebecca L. Brock, David Dilillo

Department of Psychology: Faculty Publications

Maternal trauma has been linked with problematic parenting, including both harsh and permissive behaviors. However, little is known about mechanisms accounting for this association. The current study examined the potential impact of posttraumatic stress disorder (PTSD) and emotion regulation on dysfunctional parenting behaviors in a sample of community mothers. We hypothesized a mediation model wherein PTSD would be associated with dysfunctional parenting (i.e., lax and overreactive behaviors) indirectly through deficits in maternal emotion regulation. Seventy-eight community mothers of 18- to 36-month-old children were administered the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and 19 mothers met criteria for PTSD. Mothers …

Dnmt3a In The Hippocampal Ca1 Is Crucial In The Acquisition Of Morphine Self‐Administration In Rats, Jian-Jun Zhang, Feng-Ze Jiang, Wei Zheng, Ying Duan, Su-Bo Jin, Fang Shen, Jing Liang, Ming Li, Nan Sui

Department of Psychology: Faculty Publications

Drug‐reinforced excessive operant responding is one fundamental feature of long-lasting addiction‐like behaviors and relapse in animals. However, the transcriptional regulatory mechanisms responsible for the persistent drug‐specific (not natural rewards) operant behavior are not entirely clear. In this study, we demonstrate a key role for one of the de novo DNA methyltransferase, DNMT3a, in the acquisition of morphine self‐administration (SA) in rats. The expression of DNMT3a in the hippocampal CA1 region but not in the nucleus accumbens shell was significantly up‐regulated after 1‐ and 7‐day morphine SA (0.3 mg/kg/infusion) but not after the yoked morphine injection. On the other hand, saccharin …


Salivary Total Immunoglobulin G As A Surrogate Marker Of Oral Immune Activity In Salivary Bioscience Research, Jenna L. Riis, Crystal I. Bryce, John L. Stebbins, Douglas A. Granger Jan 2019

Salivary Total Immunoglobulin G As A Surrogate Marker Of Oral Immune Activity In Salivary Bioscience Research, Jenna L. Riis, Crystal I. Bryce, John L. Stebbins, Douglas A. Granger

Department of Psychology: Faculty Publications

The integration of salivary biomeasures in biobehavioral, psychophysiological, and clinical research has greatly expanded our ability to study the biopsychosocial processes underlying health. Much of this research, however, has failed to adequately assess and adjust for the impact of oral immune activity on salivary biomeasure concentrations and associations with serum levels. Aiming to improve the validity and reliability of salivary biomeasure data, we examine salivary total Immunoglobulin G (IgG) as a potential surrogate marker of oral inflammation and immune activity. During a single study visit in Baltimore, Maryland, healthy young adult participants provided matched blood and saliva samples (N …


Adhd And Self-Regulation In The Workplace, Kristine Lynne Barnett Jan 2019

Adhd And Self-Regulation In The Workplace, Kristine Lynne Barnett

Walden Dissertations and Doctoral Studies

Attention-deficit/hyperactivity disorder (ADHD) diagnosed during childhood can continue into adulthood, but most research on the topic has been done on children and adolescents. This research focus has thus often left out the population of adults with this disorder. In particular, there is little research on the role that self-regulation plays in the lives of adults on several life domains, especially in the workplace. The purpose of this qualitative, phenomenological study was to understand the role that self-regulation plays in the occupational functioning of adults with ADHD. Self-regulation theory provided the tenets that were used to examine how adults with ADHD …

Race As A Predictor Of Recidivism Risk: An Epidemiological Analysis, Femi Folorunsho Jan 2019

Race As A Predictor Of Recidivism Risk: An Epidemiological Analysis, Femi Folorunsho

Walden Dissertations and Doctoral Studies

Prisoner recidivism is a problem of great social importance, as recidivism represents a failure of the rehabilitative goal of incarceration. The problem addressed in this study was the lack of accurate estimates of race as a predictor of recidivism risk in the United States, after taking demographics and criminal variables into account. Applying the life-course theory of recidivism, the purpose of this archival, epidemiological study was to calculate whether recidivism risk varied based on race, across different seriousness levels of commitment offense and number of prior arrests, among a sample of male federal prisoners released from custody. A Cox proportional …


Career Pathway And Leadership Attributes Of Academic Administrators At Historically Black Colleges And Universities, Dyanne Mitchell-Williams Jan 2019

Career Pathway And Leadership Attributes Of Academic Administrators At Historically Black Colleges And Universities, Dyanne Mitchell-Williams

Walden Dissertations and Doctoral Studies

Academic administrators at historically Black colleges and universities (HBCUs) are faced with multiple challenges regarding retention of students, funding, and maintaining status as an HBCU, yet little is understood about how and why leaders choose a particular career pathway. This lack of understanding creates opportunities for failure related to turnover in leadership, funding discrepancies, and lower rates of retention and persistence for students. Using Maslow's needs theory as the foundation, the purpose of this descriptive study was to better understand the career pathways of established executive level leaders atin HBCUs in order to determine attributes of success among leaders with …


Biological Risk Profiles Among Latino Subgroups In The Health And Retirement Study, Catherine García, Jennifer A. Ailshire Jan 2019

Biological Risk Profiles Among Latino Subgroups In The Health And Retirement Study, Catherine García, Jennifer A. Ailshire

Department of Sociology: Faculty Publications

Background and Objectives: Latinos residing in the United States exhibit an increased risk for cardiovascular and meta- bolic diseases compared to non-Latino whites. This elevated risk contributes to a significantly higher prevalence of diabetes and hypertension among Latino adults. Examining biological risk profiles of older Latinos as a “pan-ethnic group” and by Latino subpopulations may help to explain the increased burden of disease in later life among this population. The objec- tive of this study is to document biological risk profiles among a nationally representative sample of older U.S. Latinos by nativity and country of origin.

Research Design and Methods: …


Culture And The Development Of Traditional Medicine In Africa, Rowland Edet, Oyedolapo Isaac Bello, Julianah Babajide Jan 2019

Culture And The Development Of Traditional Medicine In Africa, Rowland Edet, Oyedolapo Isaac Bello, Julianah Babajide

Department of Sociology: Faculty Publications

Traditional medicine has been the dominant healthcare system in Africa before westernization, civilization and colonialism. For people living in the rural areas, traditional medicine is easily available, accessible and affordable. The purpose of this paper is to examine how the cultural way of the life of Africans has contributed to the emergence and development of traditional therapeutic systems in the continent. By explaining the way Africans perceive illness and disease, this paper argues that various forms of healing were predicated on the sociocultural environment of the people. The paper therefore opts for concerted efforts in the development of traditional medicine …


Disability And The Immigrant Health Paradox: Gender And Timing Of Migration, Marc A. Garcia, Adriana M. Reyes, Sunshine Rote Jan 2019

Disability And The Immigrant Health Paradox: Gender And Timing Of Migration, Marc A. Garcia, Adriana M. Reyes, Sunshine Rote

Department of Sociology: Faculty Publications

Although research has documented better health and longer life expectancy among the foreign-born relative to their U.S.-born counterparts, the U.S. Mexican-origin immigrant population is diverse and the healthy immigrant effect likely varies by key structural and demographic factors such as gender, migration history, and duration in the United States. Using a life course framework, we use data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE 1993–2013) which includes Mexican-American individuals aged 65 and older to assess the heterogeneity in the immigrant health advantage by age of migration and gender. We find that age of migration …

Racial/Ethnic And Nativity Differences In Cognitive Life Expectancies Among Older Adults In The United States, Marc A. Garcia, Brian Downer, Chi-Tsun Chiu, Joseph L. Saenz, Sunshine Rote, Rebeca Wong

Department of Sociology: Faculty Publications

Background and Objectives: To document racial/ethnic and nativity differences by gender in cognitive life expectancies among older adults in the United States.

Research Design and Methods: Sullivan-based life tables were used to estimate cognitively normal, cognitively impaired/ no dementia (CIND), and dementia life expectancies by gender for White, Black, U.S.-born Hispanic, and foreign-born Hispanic adults 50 years and older in the Health and Retirement Study.

Results: Among women, the number of years spent living with dementia for Whites, Blacks, U.S.-born Hispanics, and foreign-born Hispanics was 1.6, 3.9, 4.7, and 6.0 years, respectively. For men, Whites lived 1.1 years with dementia …


Drawing On Lgb Identity To Encourage Participation And Disclosure Of Sexual Orientation In Surveys, Mathew Stange, Jolene D. Smyth, Kristen M. Olson Jan 2019

Drawing On Lgb Identity To Encourage Participation And Disclosure Of Sexual Orientation In Surveys, Mathew Stange, Jolene D. Smyth, Kristen M. Olson

Department of Sociology: Faculty Publications

This paper reports an experiment that tested how three survey cover designs—images of traditional families and individuals displaying themselves in typical gender ways; images of lesbian, gay, and bisexual (LGB) and heterosexual individuals and families; and no cover images—affected LGB people’s participation and disclosure of LGB identity and non-LGB people’s participation. Analyses showed the LGB-inclusive cover led to significantly more LGB respondents than the other designs, without significantly affecting the demographic, political, and religious makeup of the completed sample. We discuss what these findings mean for addressing two challenges: getting LGB people to respond to surveys and to disclose their …


Short Message Service Surveying With Homeless Youth: Findings From A 30-Day Study Of Sleeping Arrangements And Well-Being, Kimberly A. Tyler, Kristen Olson, Colleen M. Ray Jan 2019

Short Message Service Surveying With Homeless Youth: Findings From A 30-Day Study Of Sleeping Arrangements And Well-Being, Kimberly A. Tyler, Kristen Olson, Colleen M. Ray

Department of Sociology: Faculty Publications

Little is known about the location and consistency of sleeping arrangements among youth experiencing homelessness (YEH) and how this is linked to their well-being. This study addresses this gap using ecological momentary assessment (EMA) via short message service (SMS) surveying with 150 YEH over 30 days, to examine how various sleeping arrangements are associated with depression, marijuana use, support received, and service utilization. Results revealed that the average number of consecutive days youth stayed at any particular location varied considerably. Youth who stayed more frequently with a friend/partner or in a transitional living facility (TLF) reported fewer days of being …

Childhood Misfortune And Handgrip Strength Among Black, White, And Hispanic Americans, Natalie R. Smith, Kenneth F. Ferraro, Blakelee R. Kemp, Patricia M. Morton, Sarah A. Mustillo, Jacqueline L. Angel

Department of Sociology: Faculty Publications

Objective: Although early-life insults may affect health, few studies use objective physical measures of adult health. This study investigated whether experiencing misfortune during childhood is associated with handgrip strength (HGS) in later life.

Method: Data on childhood misfortune and adult characteristics from the Health and Retirement Study were used to predict baseline and longitudinal change in HGS among White, Black, and Hispanic American men and women.

Results: Regression analyses revealed that multiple indicators of childhood misfortune were related to HGS at baseline, but the relationships were distinct for men and women. Over the study, having one childhood impairment predicted steeper …

Factors Influencing Success In Day Treatment Programs For Children Ages 5 To 10, Leah Morken

Walden Dissertations and Doctoral Studies

Improving the success rates of children in mental health treatment is an important step to bettering lives. Day treatment programs are intermediate level treatment modalities that help children who are struggling with their mental health. Success rates differ for children in day treatment programs and several studies have been done evaluating various factors. This research addressed whether a child who had been exposed to trauma showed as much success in a program as a child that had not been exposed to trauma. Other variables were to determine if children have different levels of success based on their diagnosis. The study …


Wellness Paradigms In Predicting Stress And Burnout Among Beginning Expatriate Teachers, Kimala Proctor Jan 2019

Wellness Paradigms In Predicting Stress And Burnout Among Beginning Expatriate Teachers, Kimala Proctor

Walden Dissertations and Doctoral Studies

Research indicates that the current teacher shortage is in part due to stress and burnout. A topic that has not been examined is beginning expatriate English medium teachers (EMTs) with 5 years or less of teaching experience in the United Arab Emirates and the relationship between using individualized, self-initiated wellness paradigms and stress, job burnout, and intent to leave the teaching profession. The transactional model of stress and coping, Maslach's multidimensional theory of burnout, and the health promotion model were used to evaluate the moderating effects of the EMTs' burnout and stress levels on their wellness and intent to leave. …

Meanings Of Preconception Health To Overweight Women In An Economically Depressed County, Valeria Ninette Balogh Jan 2019

Meanings Of Preconception Health To Overweight Women In An Economically Depressed County, Valeria Ninette Balogh

Walden Dissertations and Doctoral Studies

The intention-behavior gap between receiving professional health information and transitioning to improved health behaviors prior to conception is not well understood. In order to improve preconception health across the board, a more integrative understanding of the problem must present itself. This study combined elements from the theory of planned behavior, self-determination theory, and the bioecological model of human development as it's foundation. Qualitative phenomenology and semistructured face-to-face interviews were used to gain a deeper understanding of the ways in which nine overweight and obese women described preconception intentions and beliefs and the bioecological experiences leading to those beliefs. Interpretation of …

Predictors Of Veteran Ptsd Symptom Reduction By Use Of Accelerated Resolution Therapy, Ann Witt Jan 2019

Predictors Of Veteran Ptsd Symptom Reduction By Use Of Accelerated Resolution Therapy, Ann Witt

Walden Dissertations and Doctoral Studies

Despite 30 years of research advancements, PTSD treatment remains a trial-and-error process as 22 veterans per day commit suicide to relieve their symptoms. Foa and Kozak's emotional processing theory informed this correlational study which included secondary data consisting of participants' self-rated scale scores to examine whether the independent variables number of deployments, guilt, depression, and anxiety predicted the dependent variable PTSD symptom reduction in a veteran sample with combat deployments and associated PTSD symptoms who completed accelerated resolution therapy (ART). An analysis of whether mean PTSD symptom reduction amounts differed by symptom severity levels was also completed. The study aimed …


Work-Family Conflict, Job Burnout, And Couple Burnout In High-Stress Occupations, Elizabeth Dacey Jan 2019

Work-Family Conflict, Job Burnout, And Couple Burnout In High-Stress Occupations, Elizabeth Dacey

Walden Dissertations and Doctoral Studies

One of the most common sources of stress is one's job and the struggle to balance the demands of one's job with those of one's family and/or romantic relationship. Prolonged exposure to stress can lead to burnout, and it can affect various aspects of one's life and one's emotional and cognitive well-being. Firefighters, police officers, and corrections officers are susceptible to burnout. If their well-being is compromised, it can impact their job performance, which can negatively impact society. The purpose of this study was to determine if a relationship exists between work-family conflict (time-based, strain-based, behavior-based), job burnout (exhaustion, depersonalization, …

Exploring Public Sector Leadership Through Appreciative Inquiry, Wendy L. Morton Jan 2019

Exploring Public Sector Leadership Through Appreciative Inquiry, Wendy L. Morton

Walden Dissertations and Doctoral Studies

Leadership is an important part of creating effective public organizations. Effective leaders have the potential to produce social change through positive follower and organizational outcomes, the development of important policies, and efficiently implementing public policy. The scholarly literature lacks research concerning how leadership styles translate to the public sector. The theoretical framework used to guide and support this study was Cooperrider and Whitney's appreciative inquiry. The research question explored in what ways public sector leaders affect how followers perceive themselves as social change agents in a local city-county health department. For this phenomenological study, 10 followers employed by a local …
