Experimental aesthetics research has been conducted since the nineteenth century. Interestingly, however, few studies have examined the perceived beauty of naturally shaped objects. In the current experiment, 204 participants were presented with a set of ten snowflake silhouettes that varied in complexity (perimeter relative to area); they were similarly presented with ten randomly-shaped, computer-generated, solid objects that also varied in complexity. For each stimulus set, the participants selected the single snowflake or object that was the most beautiful (Fechner’s method of choice). The results for the solid objects replicated the findings of earlier research: the most and least complex objects were chosen as the most beautiful. Moderately complex objects were rarely selected. The results for the snowflakes were different. For these visual stimuli, the least complex snowflakes were almost never chosen; only the complex snowflakes were perceived to be most beautiful, with the aesthetic preference increasing with increases in complexity.

Many of the insightful writings on clusters identify the role of entrepreneurs as key agents in the formation of firms and clusters. This thesis argues instead that local entrepreneurship is not ceased once firms and clusters are established; local entrepreneurship is about the continuous (re)creation of both businesses and clusters in global spaces. Global spaces for local entrepreneurship emphasises how firms collectively become an agent of continuous renewal. Firms enact an organising context materialising in networks that stretch relations and collaborations according to the issues being dealt with. These networks are localised but are extended beyond the geographical boundaries of clusters. One important example of this, which is in focus in this doctoral thesis, is that firms operating in clusters often interact with actors whom they have met at international trade fairs (ITFs). ITFs are those attractive events that individuals, firms and institutions attend temporarily to exhibit and trade products in foreign and national markets. This thesis is based on the work contained in a cover and five papers. Each paper contributes to the research objective and questions brought forward in the thesis cover. The empirical evidence has been mostly drawn from several case studies conducted in the Lammhult cluster in Sweden. The findings show that firms build their organising contexts in order to stretch the reach and accessibility to local and non-local actors; they jointly co-create potential opportunities. The organising contexts are mapped in networks using three proximity orders. The empirical findings report three types of situations in which there is a potential opportunity for continuous renewal. By emphasising the opportunities that can be originated when a business is not realised or when a new or improved product or process has not been generated yet, this thesis aims to stimulate a theoretical reappraisal of global spaces for local entrepreneurship. With the conceptual development of global spaces for local entrepreneurship, we put forward the idea that such spaces enhance an ability to renew firms and clusters. The underlying reason is that local entrepreneurship is centered on the social interaction between individuals, firms and/or institutions; it materialises in intended and unintended dialogical situations when there is a commitment to the continuous renewal of firms and clusters. Such dialogical situations carry with them an opportunity for co-creating new businesses, new products and new processes.

Life-stories offer an approach to understanding personality processes within a larger, developmental context. This study examines the role that one area of a person’s larger context (namely romantic relationships) plays in that person’s life-story. Specifically, the study examines whether this role changes over the lifespan. Nineteen students from a consortium of colleges in southern California, and an equal number of older adults living in a nearby retirement community, were interviewed about their romantic relationship history. The interview was semi-structured and asked participants about past and current relationships, and their most meaningful relationship overall. The interviews were coded for the themes of agency, redemption, and contamination, reported self-growth, and an additional variable called unprompted discussion of sexuality that was added based on a series of unexpected occurrences during the interviews. The results showed significant differences in both agency and unprompted discussion of sexuality between the romantic relationship narratives of young and older adults. However, no significant differences were found between the age groups on any of the other three variables, or between the sexes on any of the five variables. The results not only help us to better understand the ways in which our stories about our romantic relationships change across the lifespan, but also suggest significant differences between how younger and older adults think about love and sex.

Organizational justice and citizenship behaviors are important components that contribute to an organization’s overall effectiveness. Additionally, when an employee enters into a new organization, they form psychological contracts with their employer that consists of elements such as fairness and consultation. This study aimed to integrate the literature on organizational justice, psychological contract, and organizational citizenship behaviors, as well as look at the possible effects uncertainty may play. Specifically, it was proposed that psychological contract would mediate the moderating effects of uncertainty and justice in predicting prosocial behavioral intentions. Results did not support the hypothesis. Interestingly, however, identification with the university seemed to play a role in the uncertainty by fairness interaction in predicting perceived contract fulfillment.

Engagement is an increasingly important construct in organizational and educational settings. Research indicates that engagement is positively related to satisfaction, commitment, and performance in the workplace. This study investigated the relationship of Total Engagement to complete a thesis with Self-Determination Theory individual motivational constructs, the personality constructs of Psychological Capital and Core Self-Evaluations, and the experiential construct of Flow Propensity. The results indicated significant relationships between all constructs and engagement. Further, Psychological Capital and Flow Propensity explained 55% of the variance in Total Engagement to complete a thesis.

Past research demonstrates that fearful faces lead to an increase in temporal and a decrease in spatial gap detection, an effect proposed to be caused by a flow of input to the magnocellular pathways from the amygdala to the visual system (Bocanegra & Zeelenberg, 2009). The amygdala is also active for positive and arousing stimuli, including happy faces. The current study extends past research by presenting happy facial cues just before a gap detection task. Facial stimuli (i.e., happy/neutral faces) were presented in the periphery of the receptive field and quickly followed by a Landolt circle. Half of the participants were asked to detect a temporal gap and half a spatial gap. Response accuracy of gap detection was measured using signal detection theory. Consistent with past research on fearful faces, positive expressions were expected to facilitate temporal gap detection but not spatial gap detection when happy faces were used as cues in gap detection tasks. The current study found no difference in spatial or temporal gap detection given the emotional cue that preceded gap detection on each trial. Positive emotion did not appear to have the same impact as fear on the amygdala and visual areas involving attention.

Narcissists are not generally thought of as altruistic individuals. There are certain conditions, however, that may meet the needs of narcissistic individuals and thus elicit altruistic behavior. These conditions include recognition for the act, or adding to narcissists’ already high opinion of themselves through executing the act. Because narcissists also demonstrate impulsivity, it is also possible that a time pressure may induce narcissists as well as impulsive individuals to act altruistically. The aim of this study is to determine in what context, if any, narcissistic and impulsive individuals may display acts of altruism, specifically charitable giving. This study uses a 2 (recognized vs. unrecognized) x 2 (time limited vs. time unlimited) between groups design. Participants will complete a Stop Signal task, a charitable giving task in which recognition and time limit are manipulated, demographic questions, and two measures of narcissism. The expected results are that higher scores on overt narcissism will lead participants to donate in conditions in which they receive recognition for their donation. Higher scores on covert narcissism will lead participants to donate in conditions where they are not recognized. Individuals with higher impulsivity scores as determined by the Stop Signal task will donate in time pressured conditions over time unlimited. And furthermore, impulsivity will act as a mediator between narcissism and charitable giving in time-limited conditions. Finally, implications of these results and future directions for research are discussed.

The last few decades have seen a growing body of research on narcissism, however few studies have examined the relationship between subclinical narcissism and future orientation. The proposed study will examine how grandiose and vulnerable types of narcissism influence future orientation, and whether anxiety, depression, impulsivity and sense of control play mediating roles in this relationship. It is hypothesized that anxiety will play a mediating role between future orientation and vulnerable narcissism, but not between grandiose narcissism and future orientation. Finally, it is hypothesized that grandiose and vulnerable narcissism will be correlated within individuals. Structural Equation Modeling (SEM) will be used to test the hypotheses, and the a priori model is expected to have a good fit to the data. This study will further our understanding about how narcissists view their futures, and whether this is influenced by mediating factors.

Research has suggested that the Five Factor Model (FFM) is useful in describing personality pathology as well as personality traits. However, there appears to be disproportionate implications of the five domains for problems in living. Previous empirical research concerning the differential direction and magnitude of the relationship of the FFM domains to problems in living and personality disorder symptomatology has perhaps been limited in part by the use of a measure of the FFM that itself includes a disproportionate representation of maladaptive personality functioning across the domains. The current study also tests the hypothesis that the relationship of the FFM domains to problems in living parallels the definition of personality disorder as provided in the American Psychiatric Association’s (2000) diagnostic manual, concerning social impairment, occupational impairment, and distress. These hypotheses were tested in a sample of 79 persons who were within psychiatric treatment. The current study indicated that problems in living relate to the FFM domains in a meaningful manner and that these relationships correspond to the definition of personality disorder. Implications of the findings for future research are discussed.

This thesis investigates the properties of generic refinements of behavioral specifications. At the base of this investigation stands the view from algebraic specification that abstract data types can be modeled as algebras. A specification of a data type is formed from a syntactic part, i.e. a signature detailing the interface of the data type, and a semantic part, i.e. a class of algebras (called its models) that contains the valid implementations of that data type. Typically, the class of algebras that constitutes the semantics of a specification is defined as the class of algebras that satisfy some given set of axioms. The behavioral aspect of a specification comes from relaxing the requirements imposed by axioms, i.e. by allowing in the semantics of a specification not only the algebras that literally satisfy the given axioms, but also those algebras that appear to behave according to those axioms. Several frameworks have been developed to express the adequate notions of what it means to be a behavioral model of a set of axioms, and our choice as the setting for this thesis will be Bidoit and Hennicker’s Constructor-based Observational Logic, abbreviated COL. Using specifications that rely on the behavioral aspects defined by COL we study the properties of generic refinements between specifications. Refinement is a relation between specifications. The refinement of a target specification by a source specification is given by a function that constructs models of the target specification from the models of the source specification. These functions are called constructions and the source and target specifications that they relate are called the context of the refinement. The theory of refinements between algebraic specifications, with or without the behavioral aspect, has been well studied in the literature. Our analysis starts from those studies and adapts them to COL, which is a relatively new framework, and for which refinement has been studied only briefly. The main part of this thesis is formed by the analysis of generic refinements. Generic refinements are represented by constructions that can be used in various contexts, not just in the context of their definition. These constructions provide the basis for modular refinements, i.e. one can use a locally defined construction in a global context in order to refine just a part of a source specification. The ability to use a refinement outside its original context imposes additional requirements on the construction that represents it. An implementer writing such a construction must not use details of the source models that can be contradicted by potential global context requirements. This means, roughly speaking, that he must use only the information available in the source signature and also any a priori assumption that was made about the contexts of use. We look at the basic case of generic refinements that are reusable in every global context, and then we treat a couple of variations, i.e. generic refinements for which an a priori assumption it is made about the nature of their usage contexts. In each of these cases we follow the same pattern of investigation. First we characterize the constructions that ensure reusability by means of preservation of relations, and then, in most cases, we show that such constructions must be definable in terms of their source signature. Throughout the thesis we use an informal analogy between generic (i.e. polymorphic) functions that appear in second order lambda calculus and the generic refinements that we are studying. This connection will enable us to describe some properties of generic refinements that correspond to the properties of polymorphic functions inferred from their types and named “theorems for free” by Wadler. The definability results, the connection between the assumptions made about the usage contexts and the characterizing relations, and the “theorems for free” for behavioral specifications constitute the main contributions of this thesis.
