ABSTRACT Since 1910, Mexico has been a supplier and path for the migrating people, including Central Americans, in search of better living conditions. In fact, the flow of currencies from immigrants to their native country constitutes a lure for the dependent economic systems that they leave behind. During several migratory waves, men, particularly young ones, constituted the great migratory exodus. Beginning in the 1970s, women and children joined the waves of immigrants, and since 1994, the number of migrant children and adolescents has risen substantially. This latest immigration phenomenon is symbolized in the collection of short stories El oro del desierto (2005) by Cristina Pacheco (2005) and the documentaries Two Americans (2012) by Daniel DeVivo and Valeria Fernández and Sin país / Without Country (2011) by Theo Rigby, among others, where migrant subjects experience trauma, disappearance, and death. In addition to a sociohistorical context, these phenomena are revealed by the theoretical approaches in the works "The Intrusive Past: The Flexibility of Memory and the Engraving of Trauma" (1995) by Bessel A. van der Kolk, Unclaimed Experience: Trauma, Narrative, and History (1996) by Cathy Caruth, and Nomadic Subjects: Embodiment and Sexual Difference in Contemporary Feminist Theory (2011) by Rosi Braidotti. The reference work Diagnostic and Statistical Manual of Mental Disorders: Dsm-5. (2013) by the American Psychiatric Association was also helpful. Cited examples of literary and cinematographic representations show the psychological effects on children and adolescents migrants whose nomadic condition is shared with all human beings. To interpret this particular condition, we offer the history of immigration waves from Mexico and Central America into the United States and a psychological approach to interpret child and adolescent immigration experiences as presented in the literary and cinematic texts. Related to the migrant subjects, the selected texts highlight nomadism, traumatic event (including PTSD), and death. In addition, an identity emerges related to the nomadic subjects and those characters that live on the periphery and are framed by the hegemonic power.

ABSTRACT Post-Traumatic Stress Disorder (PTSD), depression, and insomnia are prevalent among United States (US) military veterans. This study investigates whether Brain Boosters, a new cognitive enhancement group therapy, improves symptoms of PTSD, depression, and insomnia among veterans completing the groups. The study population includes 64 US military veterans treated in the setting of the Veterans Affairs (VA) Health Care System in Phoenix, AZ. Group members were US military veterans, age 22 to 87 (mean age=53.47), who had served in or after World War II (WWII), who sought mental health care at the Phoenix VA from 2007 through 2011. Participants were treated with Brain Boosters therapy. They completed measures of mental-health related symptoms before and after this therapy. Participants were assessed pre and post group with the PTSD Checklist for military personnel (PCL-M), the Patient Health Questionnaire (PHQ-9; a measure of depression symptoms), and the Insomnia Severity Index (ISI). Statistical analyses were done with paired samples t-tests and McNemar's tests, using SPSS. The hypotheses were that symptoms of PTSD, depression, and insomnia would show statistically significant improvement with Brain Boosters therapy. Results supported the hypotheses that symptoms of PTSD and depression would improve significantly. Insomnia did not show significant improvement. The results showed the mean PCL-M score was 54.84 before Brain Boosters therapy and 51.35 after (p= 0.008). The mean PHQ-9 score was 15.21 before Brain Boosters therapy and 13.05 after (p= 0.002). The mean ISI score was 15.98 before Brain Boosters Therapy and 14.46 after (p= 0.056). Although this is a nonrandom, uncontrolled trial, findings nevertheless suggest that Brain Boosters may be an effective therapy to reduce PTSD symptom severity and depression symptom severity. This may be especially important for veterans seeking alternatives to pharmacological intervention or traditional therapeutic interventions.

Military veterans have a significantly higher incidence of mild traumatic brain injury (mTBI), depression, and Post-traumatic stress disorder (PTSD) compared to civilians. Military veterans also represent a rapidly growing subgroup of college students, due in part to the robust and financially incentivizing educational benefits under the Post-9/11 GI Bill. The overlapping cognitively impacting symptoms of service-related conditions combined with the underreporting of mTBI and psychiatric-related conditions, make accurate assessment of cognitive performance in military veterans challenging. Recent research findings provide conflicting information on cognitive performance patterns in military veterans. The purpose of this study was to determine whether service-related conditions and self-assessments predict performance on complex working memory and executive function tasks for military veteran college students. Sixty-one military veteran college students attending classes at Arizona State University campuses completed clinical neuropsychological tasks and experimental working memory and executive function tasks. The results revealed that a history of mTBI significantly predicted poorer performance in the areas of verbal working memory and decision-making. Depression significantly predicted poorer performance in executive function related to serial updating. In contrast, the commonly used clinical neuropsychological tasks were not sensitive service-related conditions including mTBI, PTSD, and depression. The differing performance patterns observed between the clinical tasks and the more complex experimental tasks support that researchers and clinicians should use tests that sufficiently tax verbal working memory and executive function when evaluating the subtle, higher-order cognitive deficits associated with mTBI and depression.

The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks. Young adult, male Sprague Dawley rats underwent restraint stress using wire mesh (6hr/daily) for five days with two days off before restraint resumed for three weeks for a total of 23 restraint days. The groups consisted of control (CON) with no restraint other than food and water restriction yoked to the restrained groups, stress immediate (STR-IMM), which were restrained then fear conditioned soon after the end of the IRS paradigm, and stress given a rest for 6 weeks before fear conditioning commenced (STR-R6). Rats were fear conditioned by pairing a 20 second tone with a footshock, then given extinction training for two days (15 tone only on each day). On the first day of extinction, all groups discriminated well on the first trial, but then as trials progressed, STR-R6 discriminated between tone and context less than did CON. On the second day of extinction, STR- IMM froze more to context in the earlier trials than compared to STR-R6 and CON. As trials progressed STR-IMM and STR-R6 froze more to context than compared to CON. Together, CON discriminated between tone and context better than did STR-IMM and STR-R6. Sucrose preference, novelty suppressed feeding, and elevated plus maze was performed after fear extinction was completed. No statistical differences were observed among groups for sucrose preference or novelty suppressed feeding. For the elevated plus maze, STR-IMM entered the open arms and the sum of both open and closed arms fewer than did STR- R6 and CON. We interpret the findings to suggest that the stress groups displayed increased hypervigilance and anxiety with STR-R6 exhibiting a unique phenotype than that of STR-IMM and CON.

An increasing number of military veterans are enrolling in college, primarily due to the Post-9/11 GI Bill, which provides educational benefits to veterans who served on active duty since September 11, 2001. With rigorous training, active combat situations, and exposure to unexpected situations, the veteran population is at a higher risk for traumatic brain injury (TBI), Post Traumatic Stress Disorder (PTSD), and depression. All of these conditions are associated with cognitive consequences, including attention deficits, working memory problems, and episodic memory impairments. Some conditions, particularly mild TBI, are not diagnosed or treated until long after the injury when the person realizes they have cognitive difficulties. Even mild cognitive problems can hinder learning in an academic setting, but there is little data on the frequency and severity of cognitive deficits in veteran college students. The current study examines self-reported cognitive symptoms in veteran students compared to civilian students and how those symptoms relate to service-related conditions. A better understanding of the pattern of self-reported symptoms will help researchers and clinicians determine the veterans who are at higher risk for cognitive and academic difficulties.

Post-traumatic stress disorder is prevalent in refugees. The population of refugees in the United States is continuing to increase, of which the majority of the incoming refugees are children. A more comprehensive approach is needed to assess children for PTSD. This creative project involved reviewing existing literature on refugees in the United States, child refugees, Erik Erikson's stages of psychosocial development, and available and applicable PTSD assessment tools. I developed a reference chart that compared the available assessment tools. I recognized that a PTSD assessment tool for refugee children does not exist. In response, I created an approach to assessing PTSD in refugee children ages 5-12. In creating this toolkit, I determined who is appropriate for administering the assessment, discovered how to create trust between the clinician and the child, created the assessment tool, including implementation instructions, and then provided directions on scoring and referrals. The tool itself is called the Child Refugee PTSD Assessment Tool (CRPAT-12). The creation of the CRPAT-12 will hopefully be disseminated and will encourage refugee resettlement organizations to assess children for PTSD upon intake. Early identification of symptoms of distress will help the child receive the appropriate treatment and will help prevent more extreme mental health complications.

The interplay between Post Traumatic Stress Disorder (PTSD) and self-efficacy lies in the efficacy-activated processes that comprise an individual’s cognitive and belief systems. Previous research shows that low self-efficacy contributes to development and maintenance of mental disorders like PTSD, while high self-efficacy influences ability to visualize, implement, and maintain success scenarios (resilience) related to effective mental coping. Negative cognition makes it difficult to pursue a coping success scenario in the presence of overriding self-doubt and often arises because a traumatic event has made it difficult to retrieve positive self-identities or has reactivated negative self-identities. Consistent with this model, we predict that a negative association exists between self-efficacy and PTSD onset susceptibility. We employed a pre-test/post-test design using a susceptibility/resilience questionnaire to assess predisposition to PTSD. Vignettes, designed to either raise or lower self-efficacy, were used to separate participants into groups and revealed a significant interaction between low and high self-efficacy across the pre- and post-tests, supporting the assertion that high self-efficacy guards against PTSD onset susceptibility while low self-efficacy may make someone more susceptible to developing PTSD-related symptoms.

Traumatic events have deleterious effects biologically, emotionally, socially, and cognitively. Events may include violence, neglect, and abuse and are best understood through a lifecourse perspective. Preventable and treatable, traumatic exposure promotes the development of trauma symptoms including avoidance, hyperarousal, increased fear, intrusive experiences, and aggression/violence. Trauma symptomology is thought to be an underlying cause of child maltreatment and intergenerational cycles of abuse
eglect. Traumatic symptoms may interfere with the ability to work, function, and care for young children and may accompany a Post-Traumatic Stress Disorder (PTSD) diagnosis.

Although these experiences are known to be harmful, little research has focused on experiences of mothers involved in the child welfare system with young children (< 5 years). Subsequently, this study explored maternal experiences of trauma whilst calculating one of the first PTSD estimates. Types of trauma exposure, age of exposure, and event details were explored alongside history of substance use, domestic violence, and mental illness. Trauma symptom type, severity, and frequency were assessed. Utilizing adult attachment as a partial mediator, relationships between trauma exposure, trauma symptoms, and parenting were examined.

Supported by a university-community collaboration within the Safe Babies Court Teams Program in Maricopa County, Arizona, this study is exploratory and cross-sectional. A convenience sample of child welfare involved mothers (N = 141) with young children were recruited who were new clinical intakes with open court dependencies. Data on child/adult traumatic events, trauma symptoms, adult attachment, and parenting were collected. Results indicated high rates of complex/chronic trauma, specifically domestic violence and physical/sexual abuse. Mothers experienced higher than average childhood adversity/emotional abuse with significant overlap between trauma exposure and reduced mental health. PTSD rates ranged from 35-39%. Adult attachment did not to mediate trauma on parenting behaviors however strong and significant direct effects were found. Insecure-disorganized and insecure-resistant were the most dominant attachment styles.



Overall, these findings indicate the complex lifecourse nature of trauma exposure and the need to pay special attention to mental health and domestic violence histories in child welfare involved mothers of young children. Implications for social work practice, policy, and research are presented and provide impetus for continued future work.

Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Previous research indicates that survivors of Intimate Partner Violence (IPV) are at a greater risk of developing Posttraumatic Stress Disorder (PTSD) symptomatology. IPV survivors often use maladaptive coping strategies in response to IPV that place them at a higher risk for PTSD. Cultural gender roles/beliefs have been known to influence coping methods. Marianismo, a Latino/a gender role belief, has not been investigated in relation to IPV, coping strategies, and PTSD among Latinas. This study examined whether physical, psychological, or sexual abuse by a romantic partner, coping strategies, and Marianismo were associated with PTSD symptomatology among 157 college-aged Latinas. The participants completed an on-line survey that assessed IPV frequency, disengaged and engaged coping, Marianismo, and PTSD symptomatology. Hierarchical multiple regressions revealed that, regardless of IPV type, more IPV and disengaged coping strategies were the best predictors of PTSD symptomatology. Marianismo did not significantly moderate the relation between coping and PTSD. However, the strong zero-order correlation between disengaged coping and Marianismo indicated they were highly correlated variables. The study findings are consistent with previous research that suggested that coping strategies are culturally dependent on beliefs and gender role expectations. Latinas may use more disengaged coping strategies because these methods may be deemed more culturally appropriate and reflect Marianismo beliefs. Psychologists working with Latina IPV survivors need to develop culturally sensitive approaches to psychoeducation on IPV and coping strategies that empower these women within their cultural belief systems and reduce their PTSD symptomatology.
