    The effect of child gender on parental nonverbal communication
    (2019) Booth, Tiara; Newman, Rochelle; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Previous work has studied parental verbal communication and found differences based on child gender. The current study was designed to better understand any differences in maternal nonverbal communication based on child gender. The nonverbal parameters analyzed were eye contact/joint attention, gestures, positive and negative facial expressions, and open and closed body language. Previously recorded mother-child play sessions when the children were 7 months (n=103) and 24 months (n=73) were coded to assess three main questions: a) Does maternal nonverbal communication differ with child gender? b) Does maternal nonverbal communication change over time? c) Does maternal nonverbal communication effect vocabulary outcomes at 24 months? Mothers used more positive facial expressions with girls at 7 months and more gestures with boys at 24 months. Mothers were consistent in their use of positive facial expressions and gestures over time. Finally, there was no apparent relationship between maternal nonverbal communication and vocabulary.

    The importance of female phenotype in determining reproductive potential and recruitment in Atlantic coast striped bass (Morone saxatilis)
    (2012) Peer, Adam Christopher; Miller, Thomas J; Marine-Estuarine-Environmental Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The influence of female phenotype on the reproductive potential of Atlantic coast striped bass is addressed in three key areas of research. The importance of the environment in shaping maternal phenotype was evaluated using a spawning stock time-series to evaluate possible environmental drivers of female migration timing in the Chesapeake Bay. Results showed that local and recent water temperature was the primary factor influencing timing of movement onto spawning grounds, with higher temperatures resulting in early movements. Next, two approaches were used to evaluate the influence of female energetic condition on reproductive potential. First, a field approach was used to test the hypothesis that relative total female condition (hereafter condition) has a positive influence on pre-fertilized indicators of reproductive potential (i.e., probability of spawning, relative fecundity, and relative oocyte volume). Results indicated that condition had a positive influence on residual fecundity, residual oocyte volume and indirectly on the probability of spawning. In the second approach, a laboratory experiment was conducted to test the hypothesis that female condition has a positive effect on offspring size, growth and survival. The null hypothesis that the maternal influences on offspring phenotype did not differ in the Chesapeake Bay and Roanoke River populations also was tested. In contrast to the effects of female condition on pre-fertilized indicators of reproductive potential, condition had no influence on offspring phenotype in either population. Instead, post-spawn gutted weight alone had the greatest influence on offspring phenotype, although to a lesser and potentially insignificant degree in the Roanoke River. Finally, a preliminary field evaluation was conducted in the Patuxent River, MD to determine whether maternal influences can lead to disproportionate numbers of mothers contributing to juvenile recruitment. Specifically, this study evaluated whether the variance in the distribution of half-sibling families was greater than expected by random reproductive success (i.e., Poisson process). If true, it was expected that the effective population size would be orders of magnitude smaller than the census size. Results provide preliminary evidence for higher than expected variance in reproductive success; however, methodological improvements will be necessary to confirm these results in the future

    The relationship between maternal speech clarity and infant language outcomes
    (2011) McColgan, Kerry; Ratner, Nan B; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Mothers' use of infant-directed speech (IDS) may assist infants in decoding language input. IDS is characterized by exaggerated prosodic features (Fernald, 1989), shorter mean length of utterance (Cooper, 1997; Bernstein Ratner, 1996), repetition (Bernstein Ratner, 1996), and more highly clarified acoustic qualities (Bernstein Ratner, 1984; Malsheen, 1980) in comparison to speech directed to adults. However, it is not yet known to what extent such measures of maternal input have long-term impacts on language development. This thesis seeks to test the overarching hypothesis that children who receive more clarified speech input during the prelinguistic stage may be expected to have better language skills at an earlier age than children who receive poorer quality input.

    Myth and the Maternal Voice: Mediation in the Poetry of Vénus Khoury-Ghata
    (2009) Braswell, Margaret Anne; Brami, Joseph; Modern French Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Born under the French Mandate in Lebanon, Paris-based Francophone poet and novelist Vénus Khoury-Ghata represents a generation of Lebanese writers who have witnessed Lebanon's evolution from a newly independent state to a twenty-first century nation struggling to survive the devastation of civil war and regional conflict. Like many of her compatriots who have chosen exile and whose mother tongue is Arabic, Khoury-Ghata's negotiation between two languages and cultures nurtures an oeuvre that reflects the tensions and provocations of a dual Franco-Lebanese identity. An examination of her poetry represents an opportunity to direct more attention to a poet whose passionate representation of her native country and the pathos of the human figure memorializes in verse personal and collective tragedy. Khoury-Ghata's narrative-driven poems reveal the dynamics of accommodating differences by promoting encounter and integration, while recognizing that confrontation is not entirely unavoidable. Seeking to reconcile the distance and the passage of time that separate the poet from her origins, as well as linguistic and cultural differences that divide self and society, her approach evokes the contemporary poet's quest for a rapprochement, however ephemeral, with the Other, often in the context of an autobiographical project that merges History and myth. Her consistent evocation in writing and interviews of her dual identity invites an examination of her verse in the framework of theoretical notions based on binary structures. Informed by surrealist and magical realist strategies, as well as French and Arab poetic legacies, Khoury-Ghata's verse expresses a paradigm of inversion that renders the common narrative fantastic, transforms the ordinary housewife into a supernatural heroine, and sanctifies the abject. Evocations of language and myth affiliated with this subversive dynamic encourage the investigation of their significance in the framework of binary structures that privilege the negative and the nocturnal. Julia Kristeva's theory of poetic language provides one method for the analysis of Khoury-Ghata's portrayal of the maternal figure and maternal language as negative and subversive feminine forces. This study will underscore how the poet's integration into her text of signifiers of Arabic, orality, and pre-verbal impulses, weaves the maternal voice and gestures into a mythical narrative. In addition, French myth critics such as Gilbert Durand and Pierre Brunel propose various reflections on the development of mythical structures, archetypes, and themes, whose evocations in Khoury-Ghata's verse underscore a poetic strategy of the recovery and revival of her Lebanese origins linked to a broader Mediterranean culture. Durand's isotopic classification of images according to a dichotomous paradigm of the diurnal and nocturnal throws into relief the archetype of the nocturnal Grande déesse whose enigmatic (re)productive power suggests correspondences with the maternal dynamic in Kristeva's semiotic theory, as well as the surrealist médiatrice, and Wendy Faris' conception of the mystical feminine in magical realist strategies. The theme of mediation persists in the poet's mythico-poetic approach that promotes the contact and fusion of contrary forces in diverse "narratives in verse" representing cosmogonic myth, the myth of the primitive Other, biomythography, folktale and fable, and the interaction of myth and memoir. This inquiry demonstrates the durability and plasticity of binary structures of myth and language that mediate personal and collective identities challenged by the potential polarization of languages, cultures, and genders.
