No full textabstract: We present a model explaining the elemental enrichments in Jupiter's atmosphere, particularly the noble gases Ar, Kr, and Xe. While He, Ne, and O are depleted, seven other elements show similar enrichments (~3 times solar, relative to H). Being volatile, Ar is difficult to fractionate from H[subscript 2]. We argue that external photoevaporation by far-ultraviolet (FUV) radiation from nearby massive stars removed H[subscript 2], He, and Ne from the solar nebula, but Ar and other species were retained because photoevaporation occurred at large heliocentric distances where temperatures were cold enough (lesssim 30 K) to trap them in amorphous water ice. As the solar nebula lost H, it became relatively and uniformly enriched in other species. Our model improves on the similar model of Guillot & Hueso. We recognize that cold temperatures alone do not trap volatiles; continuous water vapor production is also necessary. We demonstrate that FUV fluxes that photoevaporated the disk generated sufficient water vapor in regions [< over ~]30 K to trap gas-phase species in amorphous water ice in solar proportions. We find more efficient chemical fractionation in the outer disk: whereas the model of Guillot & Hueso predicts a factor of three enrichment when only <2% of the disk mass remains, we find the same enrichments when 30% of the disk mass remains. Finally, we predict the presence of ~0.1 M [subscript ⊕] of water vapor in the outer solar nebula and protoplanetary disks in H II regions.Copyright IOP Publishing.

The effects of status motives on consumer behavior
No full textHumans possess a fundamental motivation to signal social status, which has been defined as a higher perceived position compared to others that garners an individual more respect and admiration (Bellezza, Gino, and Keinan 2014; Dubois and Ordabayeva 2015; Dubois, Rucker, and Galinsky 2012). Attaining and signaling high social status is an important, fundamental human motivation that can affect consumer behavior (Bird et al. 2005; Bird, Smith, and Bird 2001; Durante and Griskevicius 2016). The current dissertation contributes to the literature on the antecedents and downstream consequences of status-signaling motivations.
Although the majority of the literature on status signaling suggests that such motivations enhance conspicuous indulgence (e.g., spending to signal wealth), Essay 1 demonstrates that status motives can lead to displays of self-control (e.g., choices of healthier foods and self-control enhancing technologies instead of indulgent foods and entertainment technologies). This finding is important because consumers often struggle to engage in self-control (Brendl, Markman, and Messner 2003), and this work highlights one motivation, status signaling, that consumers can use to prompt such behavior. Furthermore, this finding helps marketers understand the nuance in using status-signaling appeals to sell non-luxury products, which may ultimately increase their sales.
Essay 2 introduces a novel antecedent to status signaling. Specifically, it demonstrates that parenthood predicts status-signaling behavior, in that parents are more likely than non-parents to engage in conspicuous (vs. inconspicuous) luxury consumption. This occurs in part because parents believe that their social status will impact their living children. This research contributes to a growing literature on the cognitive processes behind the consumption behaviors of parents. The findings in this essay are an important addition to extant literature because parents are assumed to be warm, protective, helpful, and generous (Hodges and Park 2013) – traits that seem at odds with a desire for conspicuous consumption, which is often born out of a desire for personal gain (Dubois and Ordabayeva 2015; Lee and Shrum 2012; Torelli, Monga, and Kaikati 2012). By highlighting this novel, counterintuitive antecedent to status signaling, this work also reveals how firms may better anticipate parents’ product preferences.Ph.D.Includes bibliographical reference
'Only connect': Chunder Loo, Monga Khan and Australia's fugitive South Asians
No full textTHE PEOPLES OF the Indian subcontinent have a significant presence in contemporary Australian culture: as the second-largest non-European cohort of the population (after Chinese-born Australians) and the fourth-largest immigrant ethnic group; as Sri Lankan refugees languishing in offshore immigration detention; and as Melbourne taxi-drivers demonstrating against physical assault. More positively and more individually, we recognise the persons of test cricketers Usman Khawaja and Lisa Sthalekar; author, journalist and former SBS newsreader Indira Naidoo; comedian Nazeem Hussain; Melbourne artist Textaqueen; and Sydney rapper L-FRESH the LION – not to mention that other Lion, the Oscar-nominated movie starring Dev Patel in the character of adopted Australian boy Saroo Brierley. We are also regularly reminded of contemporary Indian Australians by the familiar image of Bengali hawker Monga Khan, one of the so-called ‘Afghan cameleers’ who sought exemption from the provisions of the Immigration Restriction Act 1901, and whose striking profile features in Peter Drew’s ongoing multiculturalist ‘Aussie’ street poster campaign

No full textHow the search for meaning in life affects reactions to brand extensions
No full textMy dissertation assesses the effect of the search for meaning in life on consumer evaluations of brand extensions. Results from six studies demonstrate that for high hedonic brand extensions, consumers who are searching for meaning in life (vs. not searching) have more favorable brand extension evaluations. In contrast, no such difference emerges for low hedonic brand extensions. This is because high hedonic brand extensions provide excitement which fulfills the need for sensation-seeking for those who are searching for meaning in life (vs. not searching). When the sensation-seeking goal of those who are searching for meaning is fulfilled, the effect of searching for meaning in life on evaluations of hedonic brand extension dissipates. Furthermore, restoring meaning through counterfactual thinking and priming holistic thinking attenuates the effect of meaning in life on brand extension evaluations. To my knowledge, my research is the first to examine how the search for meaning in life—an overlooked concept in the marketing domain can affect consumer evaluations of different brand extensions. Moreover, my research identifies the need for sensation-seeking as the underlying mechanism driving the effect of the search for meaning in life on consumer responses to different types of brand extensions.Ph.D.Includes bibliographical reference
The effects of chance and romantic motives on consumer preferences
No full textMy dissertation advances our understandings about how chance and romantic motives influence consumer behavior. The first essay examines why chance events are often perceived more favorably and how such events impact the consumer experience. A series of studies demonstrate that consumers come to infer a stronger link between a chance event and their own self-concept. This increased self-product connection occurs as a means to restore a sense of control over chance events. This effect occurs regardless of limited mental resources, suggesting that the proposed effect is not due to increased elaboration during chance encounters. Consistent with the conceptualization, this effect is attenuated when control is restored, when the product has a negative valence, and when consumers are led to focus on others and not the self. This research is the first to examine the hidden factors that lead chance to become associated with good fortune. The second essay considers whether romantic pair-bond motivations influence numerical preferences. Across cultures and throughout history, the number “2” has been symbolic of a romantic pair bond. I propose that reminders of romance should lead people to prefer the number “2” and associated even numbers. A series of studies demonstrate that romantic motives – goals related to forming a romantic pair-bond – increase preference for the number “2” and other numbers of its parity (i.e., even vs. odd numbers) and marketing stimuli featuring even (vs. odd) numbers. This effect is specific to romantic motives and does not occur for other relationship motives such as those related to work relationship, kinship, and friendship. Consistent with a motivational perspective, the desire to form a romantic relationship statistically mediated the effect of romantic cues on preference for even numbers. Subsequently, the effect of romantic motives on preference for even numbers is suppressed when mating goals are easy to achieve or a committed romantic pair-bond (with one partner) is not important. Across two essays, my dissertation provides novel insight into the hidden influences of chance and romantic motives on the consumer experience. This work has important implications for consumers, marketers, and researchers. Namely, the conceptual underpinning advanced in both essays provides a richer understanding of two unknown, persistent biases in consumer behavior. Insights from this work can help consumers and marketers design optimal decision environments to enhance enjoyment and find work-arounds for biases in preferences, as well as advance future research.Ph.D.Includes bibliographical referencesby Aekyoung Ki
Consumer responses to marketing activities: the role of brand concepts
No full textBrands are faced not only with the decision of what to advertise, but also where to place their advertisements. Incorporating different brand concepts (i.e., abstract brand meanings), my dissertation investigates when and why different brands are helped or harmed by the placement or content of their marketing communications.
My first essay examines message placement, delineating how consumers respond to heritage brands’ social media engagement. While prior research has demonstrated many positive consequences of brands’ social media use, the role of brand concept has remained unexplored. I propose and demonstrate in six studies, including two field datasets, that for heritage brands, engaging in social media leads to less favorable brand evaluations (i.e., brand dilution). This is because social media represents openness to change values, which are perceived to be inconsistent with the tradition values that heritage brands embody. Supporting the proposed role of inconsistency, this brand dilution effect is mitigated when heritage brands emphasize relatedness, a concept that better aligns with tradition values, and when they encourage dialecticism (i.e., acceptance of inconsistencies). By examining heritage brands, I identify both the cause and the solution for brand dilution stemming from social media engagement.
My second essay examines message content by outlining the role of brand warmth in consumer responses to scarcity appeals (e.g., “only 10 available”). Prior research has examined the effect of scarcity appeals on promoted products, but their effect on the advertising brands has yet to be examined. I propose and demonstrate in four studies that using scarcity appeals leads to more positive brand evaluations, including higher behavioral intentions and more favorable attitudes, for high-warmth (vs. low-warmth) brands. This is because high-warmth brands are perceived to be well-intentioned, making the use of scarcity appeals feel less manipulative to consumers. Supporting the proposed mechanism, perceived good intentions mediate the effect of brand warmth on brand evaluations, and preventing consumers from inferring better intentions by priming the belief that scarcity appeals are profit-driven eliminates the observed effect. My work thus outlines a unique outcome of scarcity appeals, where such appeals can benefit warm brands.Ph.DIncludes bibliographical references
