Theoretical studies of the bonding, energetics and spectra of sulfur and phosphorus halides, and reactivity of divalent sulfur compounds: impact of recoupled pair bonding
… (n=2-4)—are presented in this dissertation. The bonding in the ground and excited states of these species was analyzed using generalized valence bond theory. These (and other) studies have led to a model—the recoupled pair bond (RPB) model—that provided much insight into the electronic structure …

Comparisons of Captive Gibbons’ (Hylobatidae) Intrapair Behaviors Indicative of the Pair Bond
I aimed to better understand captive gibbons’ pair bonds by studying behaviors that may indicate the relationship’s quality. I completed this research at The Gibbon Conservation Center (GCC) in Santa Clarita, California and observed four species: eastern hoolock (<em>Hoolock leuconedys</em>), Javan …

Insights into the chemistry of sulfur-containing molecules
… valence bond (GVB) theory and the recoupled pair bonding model in order to understand the chemical bonding in a variety of sulfur-containing molecules. We use the resulting insights to rationalize experimental and computational results as well as to make predictions about the structures, …

The Effects Of Courtship And Pairing Behavior On The Nonapeptide And Noradrenergic Systems Of Adult Male And Female Zebra Finches
… is evidence that nonapeptides are important in pair bonding for both male and female zebra finches (Lowrey & Tomaszycki, 2014) and treatment with an OT antagonist results in an increased latency to pair in both sexes (Pederson & Tomaszycki, 2012). Thus, the role of nonapeptides in monogamous …

An Investigation of Malaysian Secondary School Students’ Mental Models of Acid-Base Chemistry
… students’ difficulties in understanding chemical bonding, particle nature of matter and others, but relatively few on acid-base chemistry. One approach for reducing students’ learning difficulties uses model-based science teaching, which involves models and mental models. This thesis study …

The Breakup Project: using evolutionary theory to predict and interpret responses to romantic relationship dissolution
<p>The formation and maintenance of romantic pair bonds is a well-represented topic in human evolutionary sciences. This extensive body of work, drawn mostly from the field of evolutionary psychology, has proposed mechanisms for attracting a mate (e.g., resource display, physical cues), attaining a …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (taeniopygia Guttata)
… that stress can affect the propensity to form a pair bond. Data from humans and prairie voles, monogamous rodents, suggest that activation of the hypothalamic-pituitary-adrenal axis (HPA) in males increases attraction for females. Across species, females are understudied, but evidence from the …

General method for the development of models of electronic structure and bonding: covalent bonds, recoupled pair bonds and through-pair interactions
… theory and to the development of the recoupled pair bonding model. The recoupled pair bond model consists of two conceptual components, the recoupled pair bond and the recoupled pair bond dyad. The fundamental aspects of the recoupled pair bond, where the electrons that compose an atomic or …

Comparisons of the socio-behavioral differences between chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), investigating the impact of a naturally occurring polymorphic microsatellite deletion in the 5’ flanking region of arginine vasopressin receptor 1a (AVPR1a) on gene expression and sociality within the Pan genus
… have been associated with social behaviors (pair-bonding, paternal care, degree of social interest) and differential levels of expression of AVPR1a in the brains of voles. The polymorphic DupB microsatellite in chimpanzees allows the investigation of microsatellite variation 5’ of AVPR1a in …

Ecological Pressures Selecting for Singing Behavior in Primates
… (e.g. coalition signaling as well as group and pair bonding). I collected behavioral data, for as many species (n) as possible, from the primary primate behavioral literature, including vocalization (n=68), locomotion (n=99), and socio-ecological regression control variables. Data were then …

Flight Vocalizations and Displays of Adult Chimney Swifts (Chaetura Pelagica): Description and Function
… Chimney Swifts engaged in more interactive pair flights during the nest-building/egg-laying stage, when females are likely fertile, than any other stage, and significantly more than during the pre-building and nestling stages. This indicates importance of pair flights in courtship, pair …

Die Bedeutung der Paarbindung für das Fortpflanzungspotential von Papageienvögeln (Psittaciformes) : vergleichende Untersuchung zu Hormonstatus und Verhalten
Zum Erhalt vom Aussterben bedrohter Papageienvögel (Psittaciformes) ist die Nachzucht in Menschenobhut neben dem Erhalt freilebender Populationen von großer Bedeutung, die Reproduktion bestimmter Arten gelingt allerdings nur unzureichend. Als Hauptgrund dafür gilt die Zwangsverpaarung im Rahmen von …

Theoretical and computational investigations of the electron and spin correlation in chemical bonds, building a predictive bonding model with generalized valence bond theory
… physical and chemical principles of chemical bonding in various molecules, chemists can make predictions about the structures, energetics, reactivities and other properties of chemical species. The understanding of bonding is also critical to achieving one of the ultimate goals of chemists—the …
