Evaluation of a Behavior Skills Package to Teach Caregivers to Manage Disruptive Behavior during Medical and Dental Appointments

Description: Adults with developmental disabilities that live in large residential settings experience complications due to problem behavior when attending routine medical/dental appointments. This may result in sedation for clients for even the most routine medical/dental appointments. The purpose of this project was to develop a comprehensive staff training program that incorporated best practices to teach direct-support professionals behavior management techniques and best practices for transporting clients to and from routine medical/dental appointments. 4 direct-support professionals at a large residential care facility participated in this project. Multiple probes were conducted utilizing standard role-play exercises to evaluate caregiver acquisition of 16 specific skills related to client information, best practices for client transport, and behavior management. The results indicated that behavior skills training (BST) resulted in caregiver acquisition of all 16 skills during role-play exercises.

It's Going to be Different, but It's Going to be Okay: Caregiver Perspectives on Autism, Culture and Accessing Care

Description: Through ethnography influenced by public health and anthropological theory, I explored the cultural perceptions of autism among eight caregivers whose children received services from a local Dallas-Fort Worth autism treatment organization. Participant observations and semi-structured interviews with caregivers and program employees provided a rich and nuanced view into the state of care currently available in the DFW area while also highlighting areas for improvement. This research will be used to not only identify the barriers faced by North Texas Families while seeking out care,but also the strategies the organization uses when connecting with families from different backgrounds.

Ethnic and Sexual Minority Differences in the Prediction of Disordered Eating and Exercise Behaviors in College Men

Description: Despite growing evidence of their prevalence, clinical and subclinical disordered eating behaviors among men continue to be understudied phenomena. When compared to females, predictors of male disordered eating vary across ethnic groups, suggesting cultural influences on disordered eating. Moreover, gay and bisexual men experience pronounced levels of body dissatisfaction, sensitivity to societal body image standards, and subsequent disordered eating when compared to straight men and gay women. This study investigated possible differences in prediction of disordered eating among intersections of male ethnicity and sexuality. We approached this question through a transtheoretical lens that integrated intersectionality and minority stress theories. Archival data from a sample of African American, Latino, and White college men were analyzed using hierarchical multiple regression. Predictors of emotional and binge eating behaviors differed across ethnicity, in that body dissatisfaction and media internalization for African American and Latino males exhibit the strongest unique associations with emotional and binge eating behaviors, while the strongest unique predictors of emotional and binge eating behaviors among White males are depressive symptoms and low self-esteem. Moreover, African American sexual identity and depressive symptoms interact, as gay or bisexual men report stronger unique associations between depression symptoms and emotional and binge eating. All predictors (i.e., body dissatisfaction, depression symptoms, low self-esteem, media internalization, and sexual minority identity) were unable to explain sufficient variance in over exercise behaviors in African American men. Results suggest ethnicity and sexual orientation are meaningful to the experience of disordered eating in men, and that underlying mechanisms may exhibit differing associative patterns across ethnic identity. Clinicians working with ethnically and sexually diverse male disordered eating populations may use the results to better inform treatment interventions and conceptualization. These findings also support the value of intersectional quantitative methodology and the limits of relying on single-axis identity as a predictive element.

Ex-Offender Reentry: An Analysis of Current Policies and Programs

Description: Recidivism rates among ex-offender populations have consistently remained high. With over 600,000 ex-offenders being released from prison each year, reducing the rate of recidivism among the ex-offender class has become a highly debated issue. Ensuring ex-offenders successfully reintegrate into the community post-incarceration may help to reduce recidivism rates. Through a qualitative thematic analysis, this study examined various policies and program that may impact recidivism rates among ex-offenders. The policies and programs reviewed in this study were categorized among six main themes which were identified in prior literature as the most crucial elements needed for successful reintegration. The findings indicate that while many policy changes have been made to positively impact ex-offender reintegration by allowing initial access to services post-release from prison, more should be done to ensure ex-offenders actually receive needed services.

Corbicula fluminea Invasion as a Secondary Effect of Hydrilla verticillata Management via Triploid Grass Carp (Ctenopharyngodon idella)

Description: A study of Asian clam (Corbicula fluminea Müller) colonization in relation to changes in aquatic vegetation community as a result of management of Hydrilla verticillata (L. f.) Royle with grass carp was conducted at the Lewisville Aquatic Ecosystem Research Facility (LAERF), Lewisville, TX, from April 2015 through October 2016. Percent vegetation cover, C. fluminea abundance and water quality metrics (pH, turbidity, conductivity, DO, calcium, chlorophyll a) from 16 experimental subjects were analyzed. Treatments included four replicated grass carp stocking densities; 1-control with no fish stocked (n = 4), 2-low density of 40-43 fish per vegetated ha (n = 4), 3-medium density of 72-81 fish per vegetated ha (n = 4) and 4-high density of 110-129 fish per vegetated ha (n = 4). Data analysis showed statistical significance in the relation of C. fluminea abundance to percent vegetation cover (multiple linear regression, r2 = 0.820), grass carp stocking densities (two-way analysis of variance, p = <0.001) and chlorophyll a (multiple linear regression, r2 = 0.339). Findings of this research indicate the possibility that management of hydrilla had enabled establishment of secondary invasive species.

Homologs of Mammalian Lysosomal Lipase in Arabidopsis and Their Roles in Lipid Droplet Dynamics

Description: Lipid droplets (LDs) are organelles with many functions in cells and numerous protein interactors facilitate their biogenesis, maintenance, and turnover. The mammalian lipase responsible for LD turnover during lipophagy, LipA, has two candidate homologs in Arabidopsis: MPL1 and LIP1. One or both of these plant homologs may function in a similar manner to mammalian LipA, providing an LD breakdown pathway. To test this hypothesis, wild type (WT) Arabidopsis plants, MPL1 over-expressing (OE) mutants, and T-DNA insertion mutants of MPL1 (mpl1) and LIP1 (lip1) were examined for LD phenotypes in normal conditions and in environments where LD numbers are known to fluctuate. Plants to be imaged by confocal microscopy were exposed to heat stress and wounding to increase LD accumulation, senescence was induced in leaves to deplete lipids, and LDs were imaged throughout the day/night period to observe their diurnal regulation. The mutation of both MPL1 and LIP1 lead to an increase in LDs within the leaf mesophyll cells, although the spatial distribution of the LDs differed between the two mutants. mpl1 mutants had disrupted diurnal regulation of their LDs, but lip1 mutants did not. Alternately, lip1 mutants retained LDs during dark-induced senescence, and mpl1 mutants did not. Together these results suggest that MPL1 and LIP1 are likely both important for LD dynamics; however they appear have roles in different aspects of LD accumulation and turnover.

Arduino Based Hybrid MPPT Controller for Wind and Solar

Description: Renewable power systems are becoming more affordable and provide better options than fossil-fuel generation, for not only the environment, but a benefit of a reduced cost of operation. Methods to optimize charging batteries from renewable technologies is an important subject for off-grid and micro-grids, and is becoming more relevant for larger installations. Overcharging or undercharging the battery can result in failure and reduction of battery life. The Arduino hybrid MPPT controller takes the advantage of solar and wind energy sources by controlling two systems simultaneously. The ability to manage two systems with one controller is better for an overall production of energy, cost, and manageability, at a minor expense of efficiency. The hybrid MPPT uses two synchronous buck DC-DC converters to control both wind and solar. The hybrid MPPT performed at a maximum of 93.6% efficiency, while the individual controller operated at a maximum 97.1% efficiency when working on the bench test. When designing the controller to manage power production from a larger generator, the inductor size was too large due to the frequency provided by the Arduino. A larger inductor means less allowable current to flow before the inductor becomes over saturated, reducing the efficiency of the controller. Utilizing a different microcontroller like the PIC16C63A produces a much faster frequency, which will reduce the inductor size needed and allow more current before over saturation.

P-type Doping of Pulsed Laser Deposited WS2 with Nb

Description: Layered transition metal dichalcogenides (TMDs) are potentially ideal semiconducting materials due to their in-plane carrier transport and tunable bandgaps, which are favorable properties for electrical and optoelectronic applications. However, the ability to make p-n junctions is the foundation of semiconductor devices, and therefore the ability to achieve reproducible p- and n-type doping in TMD semiconducting materials is critical. In this work, p-type substitutional doping of pulsed laser deposited WS2 films with niobium is reported. The synthesis technique of the PLD target with dopant incorporation which also ensures host material stoichiometry is presented. Hall electrical measurements confirmed stable p-type conductivity of the grown films. Structural characterization revealed that there was no segregation phase of niobium in the fabricated films and x-ray phtoelectron spectroscopy (xps) characterization suggest that the p-type doping is due to Nb4+ which results in p-type behavior. Stable hole concentrations as high as 10E21(cm-3) were achieved. The target fabrication and thin film deposition technique reported here can be used for substitutional doping of other 2D materials to obtain stable doping for device applications.

When to Say It: Establishing a Verbal Cue

Description: Dog trainers sometimes teach verbal cues by saying the cue as the dog is performing the desired behavior. However, there is disagreement about when to say the cue. In this study, a pet dog was trained to go to three different apparatus, the cue for each of which was given at a different time, in a multi-element design. The cue "hoop" was given just as the dog began to move to the hoop apparatus. The cue "carrier" was given as the dog was stepping into the carrier apparatus. The cue "platform" was given after the dog was sitting on the platform apparatus. To test if the dog had learned the cues, the trainer had the dog sit and gave the cue. During testing, if only the correct apparatus was present, the dog responded to all three cues. However, when all three apparatus were present, the dog only responded correctly to the "hoop" cue. This suggests that giving the cue just as the learner is beginning to perform the desired behavior is the most effective teaching method.

Musical Priming and Operant Selection

Description: Language is a cultural construct, and the relationship between words is taught. Priming research has long investigated the relationship between related and unrelated words. Similar research has been seen in music relationships, but most of these investigate harmonic relations despite the melodic relationship being the one listeners are mostly likely to describe. Further, these studies typically measure existing relationships and do not attempt to teach a new relationship, nothing that most adults are experienced musical listeners. This study seeks to establish a new melodic relationship (the enigmatic Scale) in addition to a familiar one (the major Scale) while measuring response time to the musical sequences. A baseline was conducted in which participants listened to a musical sequence and selected via response box if the final note is consonant (major Scale) or dissonant (enigmatic Scale). Following baseline a training section occurred in which participants heard sequences ranging from 2-7 notes and were provided feedback for correct and incorrect responses. Following completion of the training participants completed a post-test identical to baseline. Behavioral results are discussed in relation to Palmer's (2009) concept of the repertoire.

Shear and Bending Strength of Cold-Formed Steel Solid Wall Panels Using Corrugated Steel Sheets for Mobile Shelters

Description: The objective of this thesis is to determine if the single sided resistance spot weld (RSW) can be used as a feasible connection method for cold formed steel (CFS) shear walls subject to lateral force of either seismic or wind loads on mobile shelters. The research consisted of three phases which include: a design as a 3D BIM model, connection tests of the resistance spot weld, and full-scale testing of the designed solid wall panels. The shear wall testing was conducted on specimens with both resistance spot weld and self-drilling screws and the results from tests gave a direct comparison of these connections when the solid wall panel was subjected to in-plane shear forces. The full-scale tests also included 4-point bending tests which was designed to investigate the wall panel's resistance to the lateral loads applied perpendicularly to the surface. The research discovered that the singled sided resistance spot weld achieved similar performance as the self-drilling screws in the applications of CFS wall panels for mobile shelters. The proposed single sided resistance spot weld has advantages of low cost, no added weight, fast fabrication, and it is a feasible connection method for CFS wall panels.

Facets of Positive Affect and Risk for Bipolar Disorder: Role of the Behavioral Activation System

Description: Bipolar disorder is characterized by disruptions in mood and affect that occur not only during mood episodes, but during euthymic periods as well. At the same time, sensitivity of the behavioral activation system (BAS) has been implicated in the disorder and is a risk marker for it. Less clear is the relationship between BAS sensitivity and positive affect, particularly lower level facets of positive affect. The aim of the present study was to examine the relationship between positive affect and vulnerability for mania as assessed using BAS sensitivity. Specifically, the link between daily levels and fluctuations of positive affect and baseline BAS sensitivity was examined. Following the hierarchical model of affect, this study also assessed the relationship between BAS sensitivity and the distinct facets of positive affect. Finally, this study examined whether BAS sensitivity moderates associations between daily rewards and positive affect. Undergraduates (N = 265) from a large university in the South were recruited to complete measures of BAS sensitivity, affect, and mood symptoms at baseline. Using ecological momentary assessment (EMA), participants completed daily surveys assessing affect and engagement with rewarding situations. An exploratory factory analysis revealed a four factor structure of positive affect, consisting of Serenity, Joviality, Attentiveness, and Self-Assurance. Greater daily levels of overall positive affect, as well as the lower order facets of Joviality, Self-Assurance, and Attentiveness, were predicted by heightened BAS sensitivity. In contrast, the facet of Serenity demonstrated minimal associations with BAS sensitivity. The study findings support a multi-faceted structure of positive affect and suggest that certain facets may be more closely related to risk for bipolar disorder. Specifically, Joviality and Self-Assurance may represent maladaptive forms of positive affect, whereas Serenity may function as a protective element against bipolar disorder.

Academic and Social Functioning of College Students with Attention-Deficit/Hyperactivity Disorder (ADHD)

Description: Attention-deficit/hyperactivity disorder (ADHD) is a complicated psychiatric disorder that is typically first diagnosed in childhood and associated with negative outcomes in adulthood such as poor academic performance and difficulties with social relationships. ADHD can be difficult to accurately diagnose in adulthood, given the absence of clear, agreed upon ADHD symptomology in adults. In the current study, two raters used psychometrically sound instruments and diagnostically valid assessment techniques on an archival dataset to create three distinct groups: ADHD [2/3 with other mental health diagnosis (OMH)], OMH only, and no diagnosis. Findings support the value of comprehensive assessment, combined with a thorough evaluation of the material by a trained clinician, for the accurate diagnosis of ADHD for research purposes. Comparisons were made across groups to infer that college students with ADHD have lower grade point averages and academic self-concept than students without mental health diagnoses. Yet, contrary to much of the current literature, college students with ADHD seem to create as strong, deep, supportive and harmonious relationships with loved ones and close friends as their non-diagnosed peers. Clinicians working with college students with ADHD may use the results of the current study to better inform conceptualization, better recognize the innate resilience college students with ADHD likely have, and inform treatment interventions.

Slogan Word Count and the Effects on Consumer Behavior

Description: Slogans can be attributed as a way in which to communicate a brand's message to its key consumer. An effectively established brand amongst targeted consumers can in turn generate profitability and ever further promote the brand. The purpose of this paper was to investigate the effectiveness of advertisements that employ vague or precise cosmetic product brand slogans among both male and female consumers. Ultimately, the end goal of marketing is to make a sale. Additionally, the purpose of this study was to determine whether or not the length of a slogan is an influential factor on the participant's motivation to purchase a cosmetic or skincare product. Data was collected through the use of survey in an online social media format, in order to test the effectiveness of different lengths of slogans for slogan recall, brand recall, brand awareness and purchase intention. Prior research and hypotheses were used to predict the concept that shorter more concise or precise slogans in this study would heighten the levels of all measured variables in the study, slogan recall, brand recall, brand awareness and purchase intention. The results of this paper conclude overall vague slogans have the potential to reach higher levels of slogan recall ability , brand recall and the intent to purchase, on the contrary shorter more precise slogans affect brand awareness at a greater level than the lengthier slogans.

OPNET Based Design and Performance Evaluation of ZigBee Networks

Description: ZigBee is a substandard of IEEE 802.15 family that is specially designed to take care of factors such as power, data rate and area that primarily affect network performance. This has controlling and monitoring capability, which finds potential applications in different sectors. ZigBee allows the concept of hybrid networks and mobility. A comprehensive analysis of ZigBee networks was carried out by constructing and simulating the networks to evaluate the performance in terms of throughput, delay, network load, and packets dropped. This research is aimed at evaluating the effect of network topology on the system performance. A careful review of simulation platforms brought the conclusion of using OPNET Modeler which has the required frame work. Different network topologies of simple and hybrid were built and simulated. Throughout the simulations, the best-case scenarios were drawn to the conclusion by the graphical analysis of parameters of evaluation. Mobile networks were constructed and simulated to investigate the effect of mobility on communication.

Analysis of Heat Transfer Enhancement in Channel Flow through Flow-Induced Vibration

Description: In this research, an elastic cylinder that utilized vortex-induced vibration (VIV) was applied to improve convective heat transfer rates by disrupting the thermal boundary layer. Rigid and elastic cylinders were placed across a fluid channel. Vortex shedding around the cylinder led to the periodic vibration of the cylinder. As a result, the flow-structure interaction (FSI) increased the disruption of the thermal boundary layer, and therefore, improved the mixing process at the boundary. This study aims to improve convective heat transfer rate by increasing the perturbation in the fluid flow. A three-dimensional numerical model was constructed to simulate the effects of different flow channel geometries, including a channel with a stationary rigid cylinder, a channel with a elastic cylinder, a channel with two elastic cylinders of the same diameter, and a channel with two elastic cylinders of different diameters. Through the numerical simulations, the channel maximum wall temperature was found to be reduced by approximately 10% with a stationary cylinder and by around 17% when introducing an elastic cylinder in the channel compared with the channel without the cylinder. Channels with two-cylinder conditions were also studied in the current research. The additional cylinder with the same diameter in the fluid channel only reduced the surface wall temperature by 3% compared to the channel without any cylinders because the volume of the second cylinder could occupy some space, and therefore, reduce the effect of the convective heat transfer. By reducing the diameter of the second cylinder by 25% increased the effect of the convection heat transfer and reduced the maximum wall temperature by around 15%. Compared to the channel with no cylinder, the introduction of cylinders into the channel flow was found to increase the average Nusselt number by 55% with the insertion of a stationary rigid cylinder, by 85% with the …

Understanding Perceptions of Community Gardens in the Dallas Area

Description: This exploratory research focuses on identifying the roles and perspectives of community gardens in the Dallas area. Results from semi-structured interviews reveal the social and political makeup of the neighborhoods where the garden projects in this study are located. While these findings highlight the benefits of gardening in the city, they can also be contested spaces. In advocating for the proliferation of garden projects in the city, community organizations would benefit from understanding the nuances of garden initiatives and the way in which they are perceived by members of the garden, nearby residents, and policy makers.

Teaching Observational Learning to Children with Autism: An In-vivo and Video-Model Assessment

Description: Observational learning (OL) occurs when an individual contacts reinforcement as a direct result of discriminating the observed consequences of other individuals' responses. Individuals with autism spectrum disorder (ASD) may have deficits in observational learning and previous research has demonstrated that teaching a series of prerequisite skills (i.e., attending, imitation, delayed imitation, and consequence discrimination) can result in observational learning. We sequentially taught these prerequisite skills for three young children with ASD across three play-based tasks. We assessed the direct and indirect effects of training by assessing OL before and after instruction across tasks and task variations (for two participants) during both in-vivo and video-model probes using a concurrent multiple-probe design. All participants acquired the prerequisite skills and demonstrated observational learning during probes of directly-trained tasks. Generalization results varied across participants. Observational learning generalized to one untrained task for one participant. For the other two participants, observational learning generalized to variations of the trained tasks but not to untrained tasks. Generalization additionally occurred during the in-vivo probes for both participants for whom we assessed this response. Implications of these findings, as well as directions for future research, are discussed.

Spectrum Analysis and Prediction Using Long Short Term Memory Neural Networks and Cognitive Radios

Description: One statement that we can make with absolute certainty in our current time is that wireless communication is now the standard and the de-facto type of communication. Cognitive radios are able to interpret the frequency spectrum and adapt. The aim of this work is to be able to predict whether a frequency channel is going to be busy or free in a specific time located in the future. To do this, the problem is modeled as a time series problem where each usage of a channel is treated as a sequence of busy and free slots in a fixed time frame. For this time series problem, the method being implemented is one of the latest, state-of-the-art, technique in machine learning for time series and sequence prediction: long short-term memory neural networks, or LSTMs.

Maximal Proposition, Environmental Melodrama, and the Rhetoric of Local Movements: A Study of The Anti-Fracking Movement in Denton, Texas

Description: The environmental problems associated with the boom in hydraulic fracturing or "fracking," such as anthropogenic earthquakes and groundwater contamination, have motivated some citizens living in affected areas such as Denton, Texas to form movements with the goal of imposing greater regulation on the industry. As responses to an environmental threat that is localized and yet mobile, these anti-fracking movements must construct rhetorical appeals with complicated relationships to place. In this thesis, I examine the anti-fracking movement in Denton, Texas in a series of three rhetorical analyses. In the first, I compared fracking bans used by Frack Free Denton and State College, Pennsylvania to distinguish the argumentative claims that are dependent on the politics of place, and affect strategies localities must use in resisting natural gas extraction. In the second, I compare campaign strategies that use local identity as a way of invoking legitimacy, which reinforces narrative frameworks of environmental risk. In the third, I conduct and analyze interviews with anti-fracking leaders who described the narrative of their movement, which highlighted tensions in the rhetorical construction of a movement as local. Altogether, this thesis traces the rhetorical conception of place across the rhetoric of the anti-fracking movement in Denton, Texas, while seeking to demonstrate the value of combining rhetorical criticism with rhetorical field methods.

Phenotypic Analysis of Medicago truncatula NPF1.7 Over-Expressing Plants Grown under Different Nitrate Conditions

Description: Plants have many nitrate transporters; in the model legume Medicago truncatula, MtNPF1.7 is among them. MtNPF1.7 is important for M. truncatula growth and it has been established that MtNPF1.7 is a high affinity nitrate transporter. M. truncatula plants with mutations in MtNPF1.7 gene show defects during plants growth, with striking abnormalities in nodule development and root architecture. Nitrogen fixation is an energy expensive process; when legumes have sufficient bioavailable nitrogen like nitrate available, it suppresses nodulation and nitrogen fixation. Previous preliminary results in our lab showed that plants constitutively expressing MtNPF1.7 have a growth phenotype in the absence of nitrate, but no data was available on how M. truncatula plants constitutively expressing MtNPF1.7 are affected by the presence of nitrate. For my research, I confirmed the preliminary results on the growth of M. truncatula plants overexpressing NPF1.7 and examined these plants' phenotypes when nitrate was not provided in the growth media and when it was provided at two different concentrations. Compared with wild type A17, plants constitutively expressing MtNPF1.7 gene grow larger, have more lateral roots and more nodules when grown in the absence of nitrate and when 0.2 mM KNO3 was provided. At 1 mM KNO3, there are fewer differences between wild type A17 and plants constitutively expressing the MtNPF1.7 gene. Compared with wild type A17, plants constitutively expressing the MtNPF1.7 gene flower earlier, which indicates MtNPF1.7 gene may have a function in plant flowering.

Understanding Affluence through the Lens of Technology: An Ethnographic Study toward Building an Anthropology Practice in Advertising

Description: This thesis describes a pilot study for a new cultural anthropology initiative at Team One, a US-based premium and luxury brand advertising agency. In this study, I explore the role and meaning of technology among a population of affluent individuals in Southern California through diaries and ethnographic interviews conducted in their homes. Using schema theory and design anthropology to inform my theoretical approach, I discuss socioeconomic and cultural factors that shape these participants' notions of affluence and influence their presentation of self through an examination of their technology and proudest possessions. I put forward a theory of conspicuous achievement as a way to describe how the affluent use technology to espouse a merit-based model of affluence. Through this model of affluence, participants strive to align themselves to the virtuous middle-class while ascribing moral value to their consumption practices. Lastly, I provide a typology of meaningful technology artifacts in the affluent home that describes the roles of their most used tech devices and how each type supports conspicuous achievement.

Simulink® Based Design and Implementation of Wireless Sensor Networks

Description: A wireless sensor network (WSN) is a spatially distributed network used to monitor the physical and environmental conditions such as temperature, pressure, sound, humidity, heat, etc. WSNs can be modeled using different simulation frameworks like OMNeT++, Prowler, Atarraya, PiccSIM, Network Simulator, etc. In this research, Simulink framework was used to model WSN system. The complete WSN consisting of transmitting nodes, communication channel, and receiver nodes are built in the Simulink framework. Orthogonal frequency division multiplexing technique was used to transmit the information. The implemented wireless sensor system behavior is studied using temperature as the measurement parameter at different values of signal to noise ratio. The plots of bit error rate versus signal to noise ratio and frame error rate versus signal to noise ratio are generated in the Simulink framework. It is easy to study the effect of different physical layer parameters on the performance of wireless sensor networks by implementing WSN in the Simulink framework.

Untangled: The Effects Family Structure Has on Juvenile Delinquency

Description: Juvenile delinquency is an issue in today's society for various reasons. This issue can result due to different motives, but family dynamics is one of the most vital factors. The current study extends prior research done in regards to the family factors that affect juvenile delinquency and what policies and programs are available to eliminate these factors. The seven family dynamics that are studied are socioeconomic status, divorce, cohabiting, family transitions, parental incarceration, parental control, as well as parental substance abuse. A subsample of policies and programs are assigned to each factor and researched of whether or not they are effective. Majority of the programs were effective and were found to minimize antisocial behaviors among adolescents. The programs that were not evaluated were still found to have a positive impact on juveniles' behaviors due to the outcomes of the policies. Investing in these programs and policies are beneficial for juveniles and the impact that family dynamics play on delinquency.
