Flexible approaches for eliciting preferences of decision makers involved in a conflict are developed along with applications to real-world disputes. More specifically, two multiple criteria decision making approaches are proposed for capturing the relative preferences of a decision maker participating in a conflict situation. A case study in logistics concerned with the conflict arising over the expansion of port facilities on the west coast of North America as well as a transportation negotiation dispute are used to illustrate how these approaches can be integrated with the Graph Model for Conflict Resolution, a practical conflict analysis methodology. Ascertaining the preferences of the decision makers taking part in a conflict constitutes a key element in the construction of a formal conflict model. In practice, the relative preferences, which reflect each decision maker’s objectives or goals in a given situation, are rather difficult to obtain. The first method for preference elicitation is to integrate an Analytic Hierarchy Process (AHP) preference ranking method with the Graph Model for Conflict Resolution. The AHP approach is used to elicit relative preferences of decision makers, and this preference information is then fed into a graph model for further stability analyses. The case study of the Canadian west coast port congestion conflict is investigated using this integrated model. Another approach is based on a fuzzy multiple criteria out-ranking technique called ELECTRE III. It is also employed for ranking states or possible scenarios in a conflict from most to least preferred, with ties allowed, by the decision maker according to his or her own value system. The model is applied to a transportation negotiation dispute between the two key parties consisting of shippers and carriers.

This study assessed the desirability for High-Occupancy/Toll (HOT) lanes in the Greater Toronto Area (GTA) through stated preference and revealed traffic volume data gathering and analysis techniques. 4,000 surveys, distributed in five sample areas, asked respondents how much they would be willing to pay to escape congestion in eight unique trip conditions. Stated preference results found considerable public support for HOT-lanes in the GTA. In six out of eight trip conditions, a majority of respondents preferred to pay to travel in express lanes rather than endure congestion. Respondent willingness to pay (WTP) mean values varied considerably by trip condition. Willingness to pay to escape congestion was influenced by trip characteristics and driver factors. Trip urgency, traffic speed, and freeway trip distance were found to be statistically significant trip characteristic indicators of WTP. Previous exposure to electronic tolling and annual household income were found to be significant driver factor indicators of WTP in most trip conditions. Respondent gender and freeway travel frequency were found to be statistically significant driver factor indicators of WTP in some trip conditions. The presence of Hwy 407-ETR, an electronically tolled by-pass to Hwy 401, allowed for an examination of the effects of Hwy 401 volume and trip urgency on driver choice to use the tolled alternative. Results indicated that trip urgency and Hwy 401 volume were correlated with Hwy 407 throughput share. During periods of high trip urgency and high Hwy 401 volume, a substantial proportion of Hwy 401/407 corridor drivers chose to pay approximately $0.20/km to escape congestion.

Adaptive reproductive behavior requires the ability to recognize and approach possible mating partners in the environment. Syrian hamsters (Mesocricetus auratus) provide a useful animal model by which to study the neural processing of sexual signals, as mate recognition in this species relies almost exclusively on the perception of social odors. In the laboratory, male hamsters prefer to investigate female odors compared to male odors, and this opposite-sex odor preference provides a sensitive measure of the underlying neural processing of sexual stimuli. In addition to chemosensory cues, reproductive behavior in hamsters also requires sufficient levels of circulating gonadal steroid hormones, which reflect the reproductive state of the animal. These chemosensory and hormone signals are processed within an interconnected network of ventral forebrain nuclei, and within this network, the posteromedial cortical amygdala (PMCo) and medial amygdala (MA) are the only nuclei that both receive substantial chemosensory input and are also highly sensitive to steroid hormones. Although a large body of evidence suggests that the MA is critical for generating attraction to sexual odors, the specific role of the PMCo in regulating odor-guided aspects of male reproductive behavior has never been directly tested. Furthermore, detailed analyses of the MA suggest that separate, but interconnected sub-regions within this nucleus process odors differently. Specifically, the anterior MA (MeA) receives the majority of chemosensory input and responds to a variety of social odors, whereas the posterodorsal MA (MePD) receives less chemosensory input but contains the vast majority of steroid receptors. In order to further elucidate how the PMCo and/or MA process sexual odors, this dissertation addressed the following research questions: (1) Is the PMCo required for the expression of either opposite-sex odor preferences or male copulatory behavior? (2) Are functional interactions between MeA and MePD required for the expression of opposite-sex odor preferences? (3) How do MeA and MePD regulate odor responses within the MePD and MeA, respectively? (4) Are odor and/or hormone cues conveyed directly between MeA and MePD? Together, these experiments provide a comprehensive analysis of the functional and neuroanatomical substrates by which the brain processes sexual odors and generates appropriate behavioral responses to these stimuli.

In many species, including Syrian hamsters, male reproductive behavior depends on the perception of odor cues from conspecifics in the environment. Volatile odor cues are processed primarily by the main olfactory system, whereas non-volatile cues are processed primarily by the accessory olfactory system. Together, these two chemosensory systems mediate appetitive reproductive behaviors, such as attraction to female odors, and consummatory reproductive behaviors, such as copulation, in male Syrian hamsters. Main and accessory olfactory information are first integrated in the medial amygdala (MA), a limbic nucleus that is critical for the expression of reproductive behaviors. MA is densely interconnected with other ventral forebrain nuclei that receive chemosensory information and are sensitive to steroid hormones. Specifically, several lines of evidence suggest that MA may generate behavioral responses to socio-sexual odors via functional connections with the posterior bed nucleus of the stria terminalis (BNST) and medial preoptic area (MPOA). It is unknown, however, how these three nuclei act as functional circuit to adaptively regulate appetitive and consummatory reproductive behaviors. Therefore, the overarching goal of this dissertation was to determine how BNST and MPOA function, both uniquely and as a circuit with MA, to generate attraction to female odors and copulatory behaviors in male Syrian hamsters. We found that BNST is required for attraction to female odors, but not for copulation, in sexually-naïve males. In contrast, MPOA is required for both attraction to female odors and for copulation in sexually-naïve males. Surprisingly, prior sexual experience mitigated the requirement of BNST and MPOA for these behaviors. Next, we found that MA preferentially transmits female odor information to BNST and to MPOA, whereas BNST relays female and male odor information equivalently to MPOA. Finally, we found that the functional connections between MA and BNST are required for attraction to female odors but not for copulation, whereas the functional connections between MA and MPOA are required for copulation but not for attraction to female odors. Ultimately, these data may uncover a fundamental mechanism by which this ventral forebrain circuit regulates appetitive and consummatory reproductive behaviors across many species and modalities.

Given the increase of Spanish- and English-speaking bilingual students in US schools, identifying the predictors of reading in this group of students is of significant importance to developing appropriate screening measures and intervention strategies. Thus, the current study evaluated the pattern of language preference in an elementary school bilingual (Spanish-English) population and its relationship with expressive and receptive vocabulary, and broad reading ability in English and Spanish. Participants were 58 Latino students ranging in age from 7 years, 5 months to 11 years, 1 month (M = 8.98, SD = .98) with 48% born in the United States. Results indicated that English expressive vocabulary partially mediated the relationship between outside language preference and English broad reading ability. In contrast, neither Spanish expressive nor receptive vocabulary mediated the relationship between outside language preference and Spanish broad reading ability.

The first chapter is based on a paper with Jin Li in fair division. It was recently discovered that on the domain of Leontief preferences, Hurwicz (1972)'s classic impossibility result does not hold; that is, one can find efficient, strategy-proof and individually rational rules to divide resources among agents. Here we consider the problem of dividing l divisible goods among n agents with the generalized Leontief preferences. We propose and characterize the class of generalized egalitarian rules which satisfy efficiency, group strategy-proofness, anonymity, resource monotonicity, population monotonicity, envy-freeness and consistency. On the Leontief domain, our rules generalize the egalitarian-equivalent rules with reference bundles. We also extend our rules to agent-specific and endowment-specific egalitarian rules. The former is a larger class of rules satisfying all the previous properties except anonymity and envy-freeness. The latter is a class of efficient, group strategy-proof, anonymous and individually rational rules when the resources are assumed to be privately owned. The second and third chapters are based on two working papers of mine in decision making under uncertainty. In the second chapter, I study the wealth effect under uncertainty --- how the wealth level impacts a decision maker's degree of uncertainty aversion. I axiomatize a class of preferences displaying decreasing absolute uncertainty aversion, which allows a decision maker to be more willing to take uncertainty-bearing behavior when he becomes wealthier. Three equivalent preference representations are obtained. The first is a variation on the constraint criterion of Hansen and Sargent (2001). The other two respectively generalize Gilboa and Schmeidler (1989)'s maxmin criterion and Maccheroni, Marinacci and Rustichini (2006)'s variational representation. This class, when restricted to preferences exhibiting constant absolute uncertainty aversion, is exactly Maccheroni, Marinacci and Rustichini (2006)'s ariational preferences. Thus, the results further enable us to establish relationships among the representations for several important classes within variational preferences. The three representations provide different decision rules to rationalize the same class of preferences. The three decision rules correspond to three ways which are proposed in the literature to identify a decision maker's perception about uncertainty and his attitude toward uncertainty. However, I give examples to show that these identifications conflict with each other. It means that there is much freedom in eliciting two unobservable and subjective factors, one's perception about and attitude toward uncertainty, from only his choice behavior. This exactly motivates the work in Chapter 3. In the third chapter, I introduce confidence orders in addition to preference orders. Axioms are imposed on both orders to reveal a decision maker's perception about uncertainty and to characterize the following decision rule. A decision maker evaluates an act based on his aspiration and his confidence in this aspiration. Each act corresponds to a trade-off line between the two criteria: The more he aspires, the less his confidence in achieving the aspiration level. The decision maker ranks an act by the optimal combination of aspiration and confidence on its trade-off line according to an aggregating preference of his over the two-criterion plane. The aggregating preference indicates his uncertainty attitude, while his perception about uncertainty is summarized by a generalized second-order belief over the prior space, and this belief is revealed by his confidence order.

This thesis aims to investigate the cola market situation in Thailand and the possibility of a local brand to compete with global brands. Due to the high value of this market, every cola company wants to get the biggest piece of the market share pie. Moreover, there is a situation regarding a global cola brand Pepsi falling into the trouble in terms of logistics and distribution channels after having been separated from its local partner company. In addition, Pepsi’s ex-partner company has launched a new cola brand into the market, a completely separate operation without any ties to Pepsi. As a result, the cola market in Thailand now has witnessed fierce competition and it attracts many players in the beverage industry to take part. Therefore, this research is designed to understand the brand preference, brand substitution, brand loyalty, taste preference, and relation between several factors from customers’ perspective to answer the possibility of a local brand competing with global brands, as well as to investigate the general cola market situation.   Information was collected by questionnaire which was answered by 420 participants, 51 percent of which were female and 49 percent were male. The results of the questionnaire found that their brand preference is actually in an opposite direction with the current cola market share, due to the effect of cola brand substitution in the market. Moreover, the research found that taste preference and gender have an influence on brand preference, while frequency of drinking and other demographics do not have any effect on brand preference

A brand could be considered to be the face of a company. The most visible aspect of a brand is the logo, but there is another perspective widely known, namely brand personality. Previous studies have acknowledged that brands, in the eyes of consumers, can be seen as having personality traits. With this knowledge, it becomes important for managers to understand what type of personality their brands possess and how therelationship between brand personality and consumers, especially their behavior, works. The purpose of this study was to explore whether brand personality has an effect on consumers‟ preference and trust towards a brand, and furthermore, whether brand personality is first influencing brand identification, as an indirect link, on its way towards preference and trust. Another aspect of this study was to make a cultural comparison between Germany and Sweden in order to find out if there are any differences in how consumers from different cultures view brand personality, and if that affects the results for brand identification, preference and trust. The findings will help marketing managers to understand the effects of brand personality, its relationship with the consumer, and moreover if the concept of brand identification is an important aspect in order to increase consumers‟ preference and trust towards a specific brand. A quantitative method was used for this study, since a large sample was thought to be needed. A total of 317 respondents provided answers for this research, out of those 190 were gathered from an online survey, while the remaining 127 answered a standard paper-based questionnaire. 181 of the respondents were German and 136 were Swedish.Two non-probability sampling techniques, snowball and convenience, were used. The questionnaires consisted of 26 questions, 13 for each brand, measuring brand personality, brand identification, preference and trust, using Likert-scales from 1 to 5. Four brands, Apple, Nike, Ikea and Mercedes Benz, were used, each restricted to one page. In order to not provide the respondents with an overwhelmingly number of questions to answer, a split of the questionnaire was made. Two questionnaires, the first with the brands Apple and Nike, and the second with Ikea and Mercedes Benz were conducted. The splitting procedure was also used to provide answers concerning cultural differences. One questionnaire was culturally neutral, while the other was culturally biased, allowing for the exploration of the effects of country of origin and consumer ethnocentric tendencies. The results of this study showed that there were indications of brand personality affecting the level of trust towards a brand among consumers. Especially, correlations were found between the brand personality dimensions of Competence and Sincerity with brand trust and between Excitement and preference. However, the concept of brand identification, as a connecting link, is found to have very weak effects on consumers‟preference and trust. Nevertheless, the findings indicate that brand personality effects consumers‟ preference and trust directly. Regarding the cultural comparison with Germany and Sweden, the responses provided an inconclusive result. In questionnaire one, the answers were fairly similar. The same could be said about questionnaire two, even though German respondents tended to produce higher scores for the brand personalities than Swedish respondents. Overall, by illustrating the results in a graph, it can be determined that the answers from both groups exhibit the same pattern. Furthermore, it was concluded that there were no clear indications of country of origin or consumer ethnocentrism effects.

Title: Purchasing Intentions of Young Thai Male towards Men's Skin Care Products Problem: Men concern more about their image than ever before. This behavior is becoming a new trend in cosmetic market. Moreover, Thailand is one of the fast growing cosmetics industry, particularly male skin care market within countries in Asia-Pacific region. However, most of the literatures have just studied on women cosmetic products. There are a few studies within male cosmetic market, despite the demands of cosmetic products are increasing among men as well as women. Purpose: This study aims to discuss the relationships between dimension of brand equity, overall brand equity, brand preference and purchase intention of men‟s skin care products among young Thai male in Bangkok. The study measures the equity of brand and identifies the impact of brand equity on brand preference and purchase intentions. Research Question: How does brand equity associate with purchasing intention of young Thai male towards skin care products? Method: Quantitative research method interpreted by the authors is applied in this research. A questionnaire-based survey is used as a tool to collect the data and the specific variables used in this paper: the dimension of brand equity, overall brand equity, brand preference, and purchase intention. Both primary and secondary types of data collection were used for this research. Conclusion: The results reveal that each dimension of brand equity, which consists of brand loyalty, brand awareness, brand association, and perceive quality have a significant impact on overall brand equity. However, brand loyalty and perceive quality have a bigger impact on brand equity than brand association and brand awareness. The impact of brand equity in itsIIconsequences supported the direct positive impact on brand preference and purchase intention. This predicate that brands with higher levels of brand equity would generate higher levels of customer brand preference. Moreover, the customers, who have high level of brand preference indicated that they have more willingness to continually purchase the specific men‟s skin care brand and this can build higher purchase intention. Last but not least, this current research also figure out that using celebrity may not be the most effective strategy to stimulate consumer purchasing intentions toward men‟s skin care product among young Thai males in Bangkok.

Gender encounter during interactive market is indeed a dynamic aspect of a marketing that affects its’ outcome which is to seal sales. The dynamic implication gender encounter has brought about the researching of both same gender and cross gender encounter in this paper. The division and independent investigate of same gender and cross gender encounter had given a clear motive on the gender preference among male and female students towards same/cross gender encounter. In actualizing this purpose, quantitative approach was use while the realist is the explanatory grid which constructed arguments in a deductive manner. In fulfilling the quantitative approach criterion, an online survey was carried out among students at Mälardalen University. Online questionnaire were distributed through a convenient sampling method and 389 valid responses were analyzed. The results shows majority of students prefers same gender encounter to cross gender. Therefore for an interactive marketing section to be successful as regards to gender differences, same gender encounter should be considered.
