abstract: With the establishment of the emerging adult developmental period and the rise of helicopter parents, attachment theory provides foundation for conceptualizing the continued involvement of helicopter parents in their emerging adults’ emotion regulation processes. This study utilized dyadic data from 66 emerging adult children and their helicopter parents to examine the association of helicopter parent-emerging adult communication in mitigating the associations between experiences of affect and stress. Specifically, the purpose of the present study was to use dyadic data to examine how communication within the helicopter parent-emerging adult relationship associates with emerging adults’ ability to regulate experiences of negative and positive affect. Both associations within the emerging adult and helicopter parent individually (actor effects) and how helicopter parents impact construct associations for emerging adults’ (partner effects) were considered. Two multilevel mediation models using Actor-Partner Interdependence Models were conducted to assess the relations between affect, stress, and helicopter parent-emerging adult communication quality for negative and positive affect separately. The positive direct effect between negative affect and stress was statistically significant for emerging adults, but not for helicopter parents, suggesting that, for emerging adults, higher perceptions of negative affect were associated with higher levels of stress. The direct and indirect effects for the mediation model examining actor and partner effects between negative affect, communication quality, and stress were non-significant for both emerging adults and helicopter parents. The direct effect between positive affect and stress was statistically significant for helicopter parents but not for emerging adults; however, the directionality of the significant association was positive and not as hypothesized. Finally, the direct and indirect effects for the mediation model examining actor and partner effects between positive affect, communication quality, and stress were non-significant for emerging adults and helicopter parents. Considerations for future studies examining aspects of attachment within emotion regulation for the helicopter parent-emerging adult relationship and the importance of considering relationship characteristics, such the relational characteristics of social support and conflict, are discussed. / Dissertation/Thesis / Doctoral Dissertation Counseling Psychology 2017

abstract: Guided by Alberts, Tracy and Trethewey's (2011) integrated theory of the division of domestic labor, this dissertation examined the influence of domestic labor response threshold (i.e., the point at which one is sufficiently disturbed by a task undone so as to feel compelled to attend to it) on domestic labor performance and domestic labor conflict. Three-hundred-ten heterosexual participants (155 marital dyads; average marriage length of 20 years) completed an online questionnaire about their performance of household labor, household labor conflict, and response thresholds. Response thresholds were assessed using traditional verbal measures as well as two visual (i.e., photographic) measures developed for this investigation. The data were analyzed using three methods of dyadic data analysis: structural equation modeling, repeated measures multivariate analysis of variance (MANOVA), and actor-partner interdependence models using multilevel modeling. Results indicate that the lower one's response threshold, and the higher one's partner's response threshold, the greater one's contributions to household tasks. Additionally, the lower one's response threshold, and the higher one's partner's response thresholds, the more likely the demand-withdrawal pattern is to emerge in domestic labor conflicts. Finally, mutual avoidance is more likely when one partner perceives that it is less costly to complete domestic work than to engage in conflict about it, or when one partner perceives that domestic labor is not a worthwhile or appropriate conflict topic. Contributions of this investigation include support for the integrated theory of the division of domestic labor, increased understanding of how individual differences (working in concert with actor sex) contribute to domestic labor allocation and conflict, a more sensitive measure of response threshold, and preliminary evidence of the "logics" of avoidance of domestic labor conflict. / Dissertation/Thesis / Ph.D. Communication 2012

abstract: This study tested the effects of two kinds of cognitive, domain-based preparation tasks on learning outcomes after engaging in a collaborative activity with a partner. The collaborative learning method of interest was termed "preparing-to-interact," and is supported in theory by the Preparation for Future Learning (PFL) paradigm and the Interactive-Constructive-Active-Passive (ICAP) framework. The current work combined these two cognitive-based approaches to design collaborative learning activities that can serve as alternatives to existing methods, which carry limitations and challenges. The "preparing-to-interact" method avoids the need for training students in specific collaboration skills or guiding/scripting their dialogic behaviors, while providing the opportunity for students to acquire the necessary prior knowledge for maximizing their discussions towards learning. The study used a 2x2 experimental design, investigating the factors of Preparation (No Prep and Prep) and Type of Activity (Active and Constructive) on deep and shallow learning. The sample was community college students in introductory psychology classes; the domain tested was "memory," in particular, concepts related to the process of remembering/forgetting information. Results showed that Preparation was a significant factor affecting deep learning, while shallow learning was not affected differently by the interventions. Essentially, equalizing time-on-task and content across all conditions, time spent individually preparing by working on the task alone and then discussing the content with a partner produced deeper learning than engaging in the task jointly for the duration of the learning period. Type of Task was not a significant factor in learning outcomes, however, exploratory analyses showed evidence of Constructive-type behaviors leading to deeper learning of the content. Additionally, a novel method of multilevel analysis (MLA) was used to examine the data to account for the dependency between partners within dyads. This work showed that "preparing-to-interact" is a way to maximize the benefits of collaborative learning. When students are first cognitively prepared, they seem to make the most efficient use of discussion towards learning, engage more deeply in the content during learning, leading to deeper knowledge of the content. Additionally, in using MLA to account for subject nonindependency, this work introduces new questions about the validity of statistical analyses for dyadic data. / Dissertation/Thesis / Ph.D. Educational Psychology 2013

abstract: This dissertation examined Mexican American individuals' romantic relationships within two distinct developmental periods, adolescence and adulthood. Study 1 used latent class analysis to explore whether 12th grade Mexican Americans' (N = 218) romantic relationship characteristics, cultural values, and gender created unique romantic relationship profiles. Results suggested a three-class solution: higher quality, satisfactory quality, and lower quality romantic relationships. Subsequently, associations between profiles and adolescents' adjustment variables were examined via regression analyses. Adolescents with higher and satisfactory quality romantic relationships reported greater future family expectations, higher self-esteem, and fewer externalizing symptoms than adolescents with lower quality romantic relationships. Similarly, adolescents with higher quality romantic relationships reported greater academic self-efficacy and fewer sexual partners than adolescents with lower quality romantic relationships. Finally, adolescents with higher quality romantic relationships also reported greater future family expectations and higher academic self-efficacy than adolescents with satisfactory quality romantic relationships. To summarize, results suggested that adolescents engaged in three unique types of romantic relationships with higher quality being most optimal for their adjustment. Study 2 used latent growth modeling to examine marital partners' (N = 466) intra- and inter-individual changes of acculturative stress, depressive symptoms, and marital quality. On average across the seven years, husbands' acculturative stress remained steady, but wives' significantly decreased; partners' depressive symptoms remained relatively steady, but their marital quality significantly decreased. Although partners' experiences of acculturative stress were less similar than their experiences of depressive symptoms and marital quality, overall their experiences were interconnected. Significant spillover and crossover effects emerged between partners' initial levels of acculturative stress and depressive symptoms and between depressive symptoms and marital quality. Moreover, changes in husbands' depressive symptoms were negatively associated with changes in their marital quality. Overall, results suggested that partners' experiences were interconnected across time. / Dissertation/Thesis / Ph.D. Family and Human Development 2014

Given the nature of couple conflict, couples are frequently tasked with mutually working towards a solution to a given problem. Effective conflict management is a key relationship resource that maintains closeness and cohesiveness (Epstein & Baucom, 2002; Overall & Simpson, 2013), whereas ineffective conflict management is generally associated with impaired relationship functioning (Gottman & Notarius, 2000; Overall & Fletcher, 2010). The overarching goal of the present thesis therefore consisted of further advancing the field’s understanding of conflict management as an interpersonal process in heterosexual couple relationships. This goal was addressed through two novel and complementary studies. The sample for both studies consisted of 179 community-based heterosexual adult couples involved in a long-term romantic relationship. During the testing session, participants completed a questionnaire package and discussed a topic of disagreement for 15 minutes. These interactions were then coded for both positive and negative conflict management behaviours. Both studies modeled these conflict management behaviours alongside crucial variables involved in couple conflict. The first study examined the ways in which partners’ adult romantic attachment orientations interact to predict their conflict management behaviours. As hypothesized, the results provide preliminary evidence that, in some cases, men’s and women’s conflict management depends on the interaction between their own and their partner’s adult romantic attachment orientation, more so than a sole individual’s attachment. The second study examined whether effective conflict management moderates the negative association between relationship satisfaction and men’s and women’s use of psychological partner aggression. Contrary to hypotheses, the results suggest that, in predicting these aggressive acts, relationship satisfaction and conflict management make fairly independent contributions. These findings are based on strong theoretical frameworks as well as a number of methodological strengths, including the observational coding of positive and negative conflict management behaviours and the implementation of sophisticated dyadic data analyses. Furthermore, by filling gaps in the existing literature, these findings offer several theoretical, empirical, and clinical implications for the field of couple conflict. As individual and collective bodies of work, the studies of the present thesis provide invaluable evidence in support of the complex and interdependent nature of couple relationships. Such findings are highly relevant to couple researchers and clinicians alike, both of whom endeavour to understand and improve couple relationship functioning.

Why do states express support for norms that go against their underlying beliefs? Scholars of policy diffusion have identified four social mechanisms -- coercion, competition, emulation, and learning -- that can lead to the spread of a common practice, a norm, in the international system. I build a formal model of the four mechanisms and apply them to actual cases of norm diffusion. The formal models are anchored by three variables that capture fundamental aspects of international society: hierarchy, neighborhood, and identity. The four different diffusion mechanisms operate on these variables, creating distinct over-time trajectories. Three important dynamic patterns are compared across different model specifications: the shape of the adoption S-curve, the power distribution among expressers and non-expressers, and the degree of regional clustering. I find that the four mechanisms produce unique signatures under many conditions, but that changes to some parameters such as initial number of expressers can obscure the identification of the diffusion mechanism. In the first empirical chapter, I apply the framework to the diffusion of quotas for women's representation. I find that quotas are adopted by weak states, and that the likely source of inspiration for quota adoption are other weak states in the same neighborhood. The empirical pattern in terms of hierarchy, neighborhood, and identity point to competition as the mechanism that drove quota diffusion. Because competition is associated with norm internalization, this finding suggests that the world is really becoming more gender equal. In the second empirical chapter, I change substantive focus to the diffusion of human rights norms. Adoption of human rights treaties seems to be associated with worse human rights behavior, but why do states that ratify human rights treaties so often fail to uphold their obligations?. I find that the Convention Against Torture (CAT) treaty is adopted first by strong states in Europe, then to weaker states in a regionally-contingent pattern. This empirical pattern is most consistent with the emulation mechanism. This implies that the anti-torture norm is not associated with internalization, and solves the previously puzzling ratification-compliance paradox.

Ce manuscrit s’intéresse principalement à l'influence de la répulsion entre électrons libres sur la réponse optique des métaux. Les modèles de matériaux classiques considèrent que la réponse d'un métal est locale -- c'est à dire que la réponse en un point dépend exclusivement des champs en ce point. La prise en compte de la répulsion entre électrons conduit à adopter une description dite non locale de la réponse métallique. Cette thèse explore de façon théorique et numérique les effets de la non-localité sur les propriétés optiques de nanostructures métallo-diélectriques dans le visible et le proche infra-rouge. A l'aide d'un modèle hydrodynamique il est montré que, de façon surprenante, les modes d'interstices plasmoniques peuvent être sensible à la non-localité pour des épaisseurs de plusieurs dizaines de nanomètres. Il est également montré que le plasmon de surface lui même peut être sensible à la non-localité à condition de considérer une interface entre le métal et un diélectrique d'indice suffisamment élevé. Nous proposons et étudions (théoriquement) ici plusieurs configurations simples et réalistes (coupleurs à prisme et à réseaux) pour la mise en évidence expérimentale de la non-localité sur des structures dont les échelles caractéristiques sont de l'ordre de plusieurs dizaines ou centaines de nanomètres. Enfin, dans une seconde partie du manuscrit, le formalisme et les considérations numériques nécessaires à l'étude du rayonnement d'un dipôle dans une structure multi-couche sont présentés en détail puis validés grâce à des comparaisons de dyadiques de Green, diagrammes de rayonnement, et taux d'émission avec des cas disponibles dans la littérature. / This manuscript is mainly focused on the influence of repulsion between free electrons on the optical response of metals. Classical material models consider that the metallic response is local -- i.e. that the response at a given point only depends on the fields at this point. Taking into account the repulsion between electrons leads to a so-called non-local description of the metalic response. This thesis explores in a theoritical and numerical way the effects of non-locality on the optical properties of metallo-dielectric nanostructures in the visible and near infrared. Using a hydrodynamical model it is shown that, suprisingly, the modes of plasmonic gaps can be sensitive to non-locality for thicknesses of several tens of nanometers. It is also shown that the surface plasmon itself can be sensitive to non-locality provided that an interface between a metal and a sufficiently high refractive index dielectric is considered. We propose and study here several simple and realictic setups (prism and grating couplers) which would allow to experimentally observe the impact of non-locality and which have characteristic scales of tens or even hundreds of nanometers. Finally, in a second part of the manuscript, the formalism and numerical considerations necessary for the study of a dipole radiation in a multi-layered structure are presented in detail and then validated thanks to comparisons of Green dyadics, radiation diagrams, and emission rates with cases avaible in the literature.

This study examined the relationship between subordinates perception of the quality of leader-member exchange (LMX) relationship, dyadic demographic factors and turnover intent in rehabilitation agencies. The sample consisted of 152 direct care employees that work with individuals with disabilities at rehabilitation organizations in the state of Illinois. In particular, the focus was on determining the best fit model that predicts turnover intent among quality of LMX, dyadic age, gender, educational level, ethnicity and duration and their two-way interactions with LMX. Participants were asked to complete the team Leader-Member Exchange scale (LMX-SLX), Turnover Intent Scale (TIS) and a demographic questionnaire. Results of the regression analysis showed that LMX significantly predicted turnover intent, β = -.272, t=-3.298, Sig. F Change = .001. None (dyadic educational level, β = -.146; dyadic ethnicity, β = .068; dyadic gender, β = .100; dyadic duration, β = -.076) of the demographic factors except dyadic age, significantly predicted turnover intent (Sig. F Change = .112). Dyadic age, β = .258, t= 2.502, p= .014 was a significant predictor, although the overall model was not significant. All (dyadic educational level_LMX, β = -.60; dyadic ethnicity_LMX, β = .037; dyadic gender_LMX, β = -.130; dyadic age_LMX, β = .071; dyadic duration_LMX, β = .071), of the interactions significantly predicted turnover intent, although the overall model was not significant. In addition, implications, limitations and delimitation, and recommendations for future research are discussed.
