A Machine Learning Approach To Predicting Alcohol Consumption In Adolescents From Historical Text Messaging Data, Adrienne Bergh May 2019

A Machine Learning Approach To Predicting Alcohol Consumption In Adolescents From Historical Text Messaging Data, Adrienne Bergh

Computational and Data Sciences (MS) Theses

Techniques based on artificial neural networks represent the current state-of-the-art in machine learning due to the availability of improved hardware and large data sets. Here we employ doc2vec, an unsupervised neural network, to capture the semantic content of text messages sent by adolescents during high school, and encode this semantic content as numeric vectors. These vectors effectively condense the text message data into highly leverageable inputs to a logistic regression classifier in a matter of hours, as compared to the tedious and often quite lengthy task of manually coding data. Using our machine learning approach, we are able to train ...


Attachment And Internalizing And Externalizing Problems In Adolescence: Exploring The Mediating Role Of Physiological Self-Regulation Capacity, Michelle A. Kuhn May 2019

Attachment And Internalizing And Externalizing Problems In Adolescence: Exploring The Mediating Role Of Physiological Self-Regulation Capacity, Michelle A. Kuhn

Clinical Psychology Dissertations

Internalizing and externalizing problems impact functioning and health in adolescence. Therefore, understanding risk and protective factors related to these behaviors is of practical interest. The proposed study examined the relationship between parent-adolescent attachment security, self-regulation capacity, and internalizing and externalizing problems. Previous studies have supported prospective links between parent-child attachment security and self-regulation capacities. Similarly, self-regulation is as a protective factor from internalizing and externalizing problems. This study proposed a mediation model combining these findings. It was hypothesized that youth with stronger parent-adolescent attachment security would demonstrate fewer internalizing and externalizing problems, and that this relationship would be mediated by ...


Attachment To The Social Construct Of Success And The Myth Of The "Good College": Effects Of Toxic Stress On Affluent Adolescents, Corey Hirsch May 2019

Attachment To The Social Construct Of Success And The Myth Of The "Good College": Effects Of Toxic Stress On Affluent Adolescents, Corey Hirsch

Doctorate in Social Work (DSW) Dissertations

The demands and expectations placed on many high school students in affluent communities require almost impossible performance levels, or even perfection, and parents, peers, high school teachers, counselors, and administrators, as well as others in affluent communities, become increasingly invested in the quest for success demonstrated by high level performance and achievement. As a result, students in affluent communities are vulnerable to experiencing extreme pressure to succeed as demonstrated by gaining admittance to a “good college.” This dissertation utilizes the foundational aspects of attachment theory to provide a framework for understanding how individuals in affluent communities develop a strong attachment ...


Promoting Resilience In Economically Disadvantaged Adolescents Through School-Based Expressive Arts Groups, Bailey Knox May 2019

Promoting Resilience In Economically Disadvantaged Adolescents Through School-Based Expressive Arts Groups, Bailey Knox

Expressive Therapies Capstone Theses

Since 2013, the majority of students served by the public school system in the United States have been considered “low-income” by the federal government. The stressors associated with low socioeconomic status significantly increase risk for social, emotional and behavioral challenges at all age levels, but can be particularly damaging to adolescents coping with heightened stress levels related to the intense multi-dimensional changes that define this developmental period. As the correlation between economic disadvantage and negative socio-emotional and academic outcomes is increasingly evidenced, schools have begun to recognize their responsibility for providing preventative mental health care to high-risk students. Over the ...


Exploring The Impact Of Positive Peer Views Of Girls On School Engagement In Middle School Girls, Christine E. Hansen May 2019

Exploring The Impact Of Positive Peer Views Of Girls On School Engagement In Middle School Girls, Christine E. Hansen

All Graduate Theses and Dissertations

This study focused on the types of messages female middle school students receive about their gender from their peers. Specifically, it looked at microaggressions, which are sexist messages from peers, and microaffirmations, which are positive and affirming messages from peers. There were four goals of this study. First, to check if the Students Affirming Girls in Middle School scale (SAG-MS), a scale created for this study, could consistently measure microaggressions and microaffirmations. Second, to look at the relationship between when girls experience puberty and microaggressions and microaffirmations. Third, to measure any differences in the number of microaggressions and microaffirmations girls ...


Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna Jan 2019

Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna

Electronic Theses and Dissertations

Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social ...


Rural Transgender And Gender-Nonconforming Individuals' Experiences With Social Media During Adolescence, Heather Lynn Anderson Jan 2019

Rural Transgender And Gender-Nonconforming Individuals' Experiences With Social Media During Adolescence, Heather Lynn Anderson

Walden Dissertations and Doctoral Studies

Suicide attempt and completion rates are significantly higher for the transgender and gender-nonconforming (TGNC) population. TGNC adolescents experience many challenges and adversities, which are compounded when they live in rural communities. The lived experiences of rural TGNC adolescents with social media were unknown and created a gap in the research. This study was grounded in transgender, gender minority stress, and resiliency theories, along with the conceptual frameworks of rural communities and grit. The purpose of this descriptive phenomenological qualitative research study was to explore the lived experiences of rural TGNC individuals (18-24-year-olds) with social media during adolescence. Data was collected ...
