My goal was to examine how experiences and behaviors of individuals and their romantic partners impact relationships on a daily basis. I conducted three separate but empirically and conceptually related studies. For all three papers, the sample was both members of heterosexual romantic relationships (N = 164 couples, 328 individuals) who completed measures each day for seven days. The papers were informed by tenets from interdependence theory and the conservation of resources model. The main purpose of the first paper was to examine a set of relational constructs (i.e., satisfaction, commitment, closeness, conflict, ambivalence, maintenance, and love) to determine which constructs fluctuated daily. All seven relational constructs showed significant within-person variability and were thus appropriate for further daily investigation. With this information, the next step was to understand how to foster positive relationships by examining what daily experiences were associated with those fluctuations. In the second paper I examined whether daily hassles and uplifts were associated with same-day and next-day feelings about the relationship. For same-day effects, I found that hassles were associated with decreased positivity and increased negativity about relationships, whereas uplifts were largely associated with increased positivity. I also found interactions between hassles and uplifts, suggestive of "blunting" effects whereby the positive effects of uplifts were nullified by high levels of hassles. For the next-day effects, I unexpectedly found that uplifts were associated with <italic>decreased</italic> positive relational constructs on the next day, possibly indicating a return to homeostatic levels. In the third paper, I moved to a more explicit examination of dyadic processes by examining both actor and partner effects and focusing on the role of relational sacrifices, or the daily changes individuals make for the sake of their romantic parnters. I expected that sacrifices would be beneficial for positive relationship quality, particularly on days characterized by low (versus high) hassles. I found support for these expectations with regards to actor, but not partner effects. Overall implications are that the everyday things that individuals experience (e.g., hassles and uplifts) and enact (e.g., sacrifices) are important considerations in fostering less negative and more positive romantic relationships.

The reformulation of pressurized metered dose inhalers (MDIs) with hydrofluoroalkanes (HFAs) from chlorofluorocarbons (CFCs) has given rise to many solubility challenges. Compounds and excipients previously used in CFCs were observed to have significantly different solubility values in HFA-134a. In this investigation, the solubility values of solid organic solutes were determined in pure HFA-134a and HFA-134a with cosolvent (0 - 20% w/w ethanol). The solubilities of solid solutes in HFA-134a were also compared with those in 2H,3H-decafluoropentane (DFP) in order to assess the suitability of DFP as a liquid model propellant. The experimental set of solutes display diverse physico-chemical properties and yielded solubility values that ranged over four orders of magnitude. The experimental solubilities were compared to calculated values obtained from ideal solubility and regular solution theory models. While the theoretical models did not offer absolute solubility estimations, a clear correlation with the ideal solubility (melting point) was noted. Further consideration utilizing multiple linear regression models afforded correlations based on molecular properties. Regression models, containing melting point and logP (or molar volume) resulted in promising correlations in both pure HFA-134a and HFA-134a/cosolvent systems where the average absolute errors ranged from 0.49 to 0.82 log units, (average factor errors of 3.09 and 6.61, respectively). In general, a linear relationship was observed between log mole fraction solubility in HFA-134a and fraction ethanol. The effect on solubilization ranged from 1.3 to 99.4 times when 20% w/w ethanol was introduced, relative to pure HFA-134a. DFP appears to be a promising liquid model for pure HFA-134a for pre-formulation calculations. A two parameter equation were found to be significant in pure HFA-134a where the average absolute error (AAE) value was 0.61 log units (average factor errors of 4.07).

Title The impact of gender and age on customer loyalty – a quantitative study of Swedish customers’ experiences of a loyalty program Authors Sara Follin &amp; Viktoria Fransson Background Building customer relationships could be done by using loyalty programs; programs which involves activities for enhancing customer loyalty (Ou, Shih, Chen &amp; Wang, 2011). To use loyalty programs as relationship marketing tactics has become popular and it is frequently used in the grocery retailing industry (Noble &amp; Phillips, 2004). Customer loyalty differences might be influenced by customers’ gender and age (Kuruvilla, Joshi &amp; Shah, 2009; Patterson, 2007). It is expected that females tend to be more loyal than males, and that older customers tend to be more loyal than younger generations (Patterson, 2007; Ndubisi, 2007). Purpose The purpose of this study is to describe the impact of gender and age on customer loyalty in the grocery retailing industry. Theory &amp; Concepts Relationship marketing, Loyalty program, Customer loyalty, Gender differences in customer loyalty, Age differences in customer loyalty Methodology This is a descriptive study with a quantitative and deductive research approach. The research strategy was survey, and data was collected from 216 respondents through a questionnaire. Data was collected around the loyalty program Willys+, which formed the sample of this study. Conclusion Customers’ gender could be one variable influencing and impacting customer loyalty, however age is not. Gender impacting customer loyalty, could be explained by potential differences in how females and males choose to shop in store as well as by the fact that the majority of the members in the loyalty program were females. Loyalty among customers belonging to different age group did not have any significant differences.

Purpose: This study aims to (1) describe and analyse the local ground operator’s role in the network of the Botswana tourism industry, (2) to investigate what factors characterize and influence their relationships with foreign tour operators, as well as (3) to provide implications for improving these relations. Methodology: This study has been conducted as a case study, where the empirical data was collected during a two months field trip to Botswana. A qualitative research method, and a deductive approach has been used. Five semi-structured interviews were conducted with ground operators to get their perspective of their own situation, and one with a person representing a governmental organisation. Most data was collected through the interviews, but participating observation also served as a source of information. The validity and reliability of the study has been enhanced by defining core concepts, interviewing several respondents, using an interview guide and recording most of the interviews. Results: Local ground operators play are crucial role in the network of Botswana’s tourism industry, as they are engaged in a high number of business relationships, are bringing the services at the destination together, and are connecting them to the tourists. They play a role as both customers and suppliers. Their relationship to tour operators abroad consists of a lot of resource ties, activity links as well as some actor bonds. Trust is found to be a very essential part of the relationship, and they perceive themselves as being dependent on the tour operators. Culture is not identified as a major influencing factor. As for managerial recommendations, a better communication in expectations and an increased adaptation of products and processes, to create customer dependence, are among the results advised.

This project investigates the development of mature student mothers’ identities in the dual contexts of constructions of the women’s at-home study practices and of their ‘responsibilities’ for their children’s development. Interviews were conducted with 23 women – all ‘new university’ students – and with their schoolaged children. I used discourse analysis focussing on language as performative and constitutive in order to understand positioning of, and by the women. I also drew upon critical developmental psychological theory and the concepts of discourse, intersubjectivity and dialogicality as epistemological resources in order to understand the women’s and children’s accounts. The methodology yielded a diversity of constructions of the women, these drawing upon a variety of discourses. The first empirical chapter addresses constructions of mature student mothers, the second, constructions of child development and the third, constructions of ‘influence’. The organisation of the empirical chapters reflects not only the importance I accorded to particular themes, but also the idea that separating mothers’ concerns and those of their children can be less fruitful in examinations of identity construction than addressing these together. The key issues that are a thread connecting the empirical chapters are time (requiring ‘balancing’ of social positions); change (in mothering practices and confidence); perceived ‘influence’ on children’s development, and relationships (including the ways in which identities are constructed in the ‘space in the middle’). Participants addressed these issues in different ways with some women positioning not spending ‘quality’ time with their children as meeting children’s developmental needs (addressed in Chapter Seven). Other important themes were mothering constructed as mundane and undervalued (in Chapter Five), children’s constructions of ‘roles’ as helpers (in Chapter Six) and perceived intersubjectivity in mother/child interactions (examined in Chapter Seven). In the concluding chapter I discuss the implications of the findings in terms of the contribution of the research to theoretical debates about motherhood, mothering and child development. I also reflect on my position as a mature student mother, examining my involvement in the research process and finally, suggest applications for the findings reported in the thesis.

As a pedestrian at the roadside, the two most informative cues as to the distance and rate of closure of a vehicle are its optical size and the rate of expansion of the optical image. In addition, the time to arrival of an approaching vehicle can be perceptually estimated by the ratio of these two variables, referred to as tau (Lee, 1976). Sensitivity to optic expansion is critical for collision avoidance and was measured in populations of adults, typically developing children, and in children with Developmental Coordination Disorder (DCD), an idiopathic condition characterised by marked impairments in motor coordination that negatively impact on activities of daily living. A central tendency was found in adults (n = 193) between 18 to 59 years of age to make significant errors in judging the approach rates of two vehicles. Inflated errors were observed in children (n = 136) between 6 to 17 years of age, with decreased sensitivity in the youngest age group (6 to 11 years). Furthermore, a significant decrement was found in children (n = 9) with DCD between 6 to 11 years of age. Across all groups, a systematic vehicle size bias was found, whereby faster small vehicles were perceived as travelling slower than larger vehicles. This pattern of results suggest that in general, observers are not utilising tau in judgments of relative approach rates for speeds typically encountered at the roadside, but instead rely on optical expansion that does not compensate for image size. Errors due to a reliance on optic size were inflated in children with DCD, potentially placing them at significantly greater risk at the roadside. To examine the decreased sensitivity observed in DCD, thresholds for detecting visual looming were measured in children (n = 11) with DCD between 6 to 11 years of age. A significant deficit was found when vehicles were presented in perifoveal vision, whereby children with DCD may perceive vehicles that are 5 seconds away as stationary if they are travelling any faster than ~14 mph. This demonstration of a low-level visual processing deficit could suggest an immaturity in the dorsal stream network and explain some of the difficulties that characterise DCD. Critically, perceptual judgments at the roadside are inextricably linked to the motoric capability of the observer. If a pedestrians crossing time is greater than the time available, collision will occur. Crossing gap thresholds were measured and compared to walking times for a single vehicle approaching at varying speeds. Children (n = 9) with DCD between 6 to 11 years of age left considerably longer temporal crossing gaps than their action capabilities necessitated. However, when children with DCD were presented with multiple vehicles in a virtual reality environment, they accepted crossing gaps at all approach speeds that were shorter than the time it would take them to cross. This suggests that children with DCD may not have the perceptual accuracy to predict their required action gaps in a road crossing situation. One explanation for these findings could be a difference in DCD in how vision is dynamically allocated to facilitate the preparation of goal-directed actions. Dynamic allocation of visual attention was assessed in a series of experiments that measured eye movement latencies and hand movement accuracy in children (n = 5) with DCD between 6 to 11 years of age. Both measures were found to be comparable in DCD with their typically developing peers regardless of task complexity, indicating that the allocation of visual attention is not deficient in children with DCD. The prospective control of movement in our everyday lives is critically depended on estimating the immediacy of approaching objects. Combined, these results indicate that children with DCD may be particularly vulnerable at the roadside due to a visual motion processing deficit, consistent with atypical function across broad neural structures such as the dorsal stream.

This thesis examines relations between the United States and Great Britain in South America between 1939 and 1945. It does so in the broader context of the economic planning for the post-war world undertaken by the US and Britain during the Second World War. Traditional interpretations of Anglo-American post-war economic planning have tended to focus on a process whereby the Franklin D. Roosevelt administration advocated a multilateral system, based on equality of access to markets and raw materials. Doubting Britain’s ability to compete successfully in such a system, the British government baulked at the US proposal and clung to its autarkic structures constructed during the interwar years. This thesis argues that relations between the US and Britain in South America followed a different and more complex pattern. In this region it was in fact Britain that eventually took the lead in advocating multilateralism. This policy was adopted following a lengthy evaluation of British policy in Latin America, which concluded that multilateralism represented the surest means of protecting British interests in South America. The US, on the other hand, demonstrated exclusionary tendencies in its policy toward Latin America, which threatened the successful implementation of a global economic system based on multilateralism. In explaining this divergence from multilateralism in the Roosevelt administration’s post-war economic planning, this thesis pays particular attention to the influence of different factions, both within the administration and in the broader US political and business establishment. By exploring Anglo-American relations in this previously neglected region, this thesis contributes toward a greater understanding of the broader process of post-war economic planning that took place between the US and Britain during the Second World War.

The literature identifies perceptions of data quality as a key factor influencing a wide range of attitudes and behaviors related to data in organizational settings (e.g. decision confidence). In particular, there is an overwhelming consensus that effective customer relationship management, CRM, depends on the quality of customer data. Data warehouses, if properly implemented, enable data integration which is a key attribute of data quality. The literature highlights the relevance of formulating problem statements because this will determine the course of action. CRM managers formulate problem statements through a cognitive process known as enactment. The literature on data quality is very fragmented. It posits that this construct is of a high order nature (it is dimensional), it is contextual and situational, and it is closely linked to a utilitarian value. This study addresses all these disperse views of the nature of data quality from a holistic perspective. Social cognitive theory, SCT, is the backbone for studying data quality in terms of information search behavior and enhancements in formulating problem statements. The main objective of this study is to explore the nature of a data warehouse's customer relationship data quality in situations where there is a need for understanding a customer relationship problem. The research question is What are the inner and inter construct associations of the quality of data warehouse customer relationship data for problem enactment? To reach this objective, a positivistic approach was adopted complemented with qualitative interventions along the research process. Observations were gathered with a survey. Scales were adjusted using a construct-based approach. Research findings confirm that data quality is a high order construct with a contextual dimension and a situational dimension. Problem sense making enhancements is a dependent variable of data quality in a confirmed positive association between both constructs. Problem sense making enhancements is also a high order construct with a mastering experience dimension and a self-efficacy dimension. Behavioral patterns for information search mode (scanning mode orientation vs. focus mode orientation) and for information search heuristic (template heuristic orientation vs. trial-and-error heuristic orientation) have been identified. Focus is the predominant information search mode orientation and template is the predominant information search heuristic orientation. Overall, the research findings support the associations advocated by SCT. The self-efficacy dimension in problem sense making enhancements is a discriminant for information search mode orientation (focus mode orientation vs. scanning mode orientation). The contextual dimension in data quality (i.e. data task utility) is a discriminant for information search heuristic (template heuristic orientation vs. trial-and-error heuristic orientation). A data quality cognitive metamodel and a data quality for problem enactment model are suggested for research in the areas of data quality, information search behavior, and cognitive enhancements.

This thesis tackles the problem of automatically synthesizing motions of close-character interactions which appear in animations of wrestling and dancing. Designing such motions is a daunting task even for experienced animators as the close contacts between the characters can easily result in collisions or penetrations of the body segments. The main problem lies in the conventional representation of the character states that is based on the joint angles or the joint positions. As the relationships between the body segments are not encoded in such a representation, the path-planning for valid motions to switch from one posture to another requires intense random sampling and collision detection in the state-space. In order to tackle this problem, we consider to represent the status of the characters using the spatial relationship of the characters. Describing the scene using the spatial relationships can ease users and animators to analyze the scene and synthesize close interactions of characters. We first propose a method to encode the relationship of the body segments by using the Gauss Linking Integral (GLI), which is a value that specifies how much the body segments are winded around each other. We present how it can be applied for content-based retrieval of motion data of close interactions, and also for synthesis of close character interactions. Next, we propose a representation called Interaction Mesh, which is a volumetric mesh composed of points located at the joint position of the characters and vertices of the environment. This raw representation is more general compared to the tangle-based representation as it can describe interactions that do not involve any tangling nor contacts. We describe how it can be applied for motion editing and retargeting of close character interaction while avoiding penetration and pass-throughs of the body segments. The application of our research is not limited to computer animation but also to robotics, where making robots conduct complex tasks such as tangling, wrapping, holding and knotting are essential to let them assist humans for the daily life.

The exclusionary nature of colorism and how it affects personal awareness of self- identity behooves us to explore the socio-psychological interplay of life choices and racial socialization. This exploratory research is positioned within the context of black males’ relationship preferences and sought comprehension of how and why their perceptions inform their choices and inclination for lighter skin tones. The manifestations of colorism in these men’s experiences influence their interactions with women and how they perceive themselves. Findings of this phenomenological study informed the researcher of various dynamics that shape interactions of race, gender and colorism and utilized Black Feminist Thought as an epistemological framework. Purposeful sampling was used for recruitment and narrative interview methods highlighted perspectives and experiences of twenty, Atlanta black males, aged 21 and older for an overall essence of their phenomenon. Hopefully, this work will prompt analytical conversations to extend research of colorism within similar group dynamics.
