This is an exploratory study, using quantitative and qualitative tools, studying younger adult students (aged 18 to 25) at a college in Ontario and proposes that younger adult notions of possible selves are strengthened through engaging with models for possible selves by conducting informational interviews with them. Research was conducted in the classroom and outside of the classroom (but on campus) using a methodological framework informed by the scholarship of teaching and learning. Anticipated outcomes include a further understanding of the researcher’s own practice in order to improve it, a further grounding of the researcher’s personal theory of practice, and useful data for other researchers interested in using possible selves as a lens to understand their teaching. The results of the study indicate that there are other issues and concerns related to notions of possible selves, including goal-setting and a sense of having choice and control over one’s fate. Implications for practice include recommendations that more opportunities and tools for the development of possible selves be offered to students and that these opportunities can be found in existing courses and programs. / Thesis (Master, Education) -- Queen's University, 2011-04-06 14:36:02.109

Loss of Control (LOC) accidents are a major threat for aviation, and contribute the highest risk for fatalities in all aviation accidents. The major contributor to LOC accidents is pilot spatial disorientation (SD), which accounts for roughly 32% of all LOC accidents. A pilot experiences SD during flight when the pilot's expectation of the aircraft's state deviates from reality. This deviation results from a number of underlying mechanisms, such as distraction, failure to monitor flight instruments, and vestibular illusions. Previous researchers have developed computational models to understand those mechanisms. However, these models are limited in scope as they do not model the pilot's knowledge of the aircraft dynamics. This research proposes a novel model to predict the best-possible-pilot-expectation of the aircraft state given vestibular and visual cues. The proposed model uses a Model-Based Observer (MBO) as the infrastructure needed to establish an “expert pilot”. Expert pilots are known to form an internal model of the operated system through training and experience, which allows the expert to generate better internal expectations of the system states. Pilots' internal expectations are enhanced by the presence of information fed through the pilots̕ sensory systems. Thus, the proposed model integrates pilot's knowledge of the system dynamics (i.e. an aircraft model) with a continuous vestibular sensory model and a discrete visual-sampling sensory model. The computational model serves to investigate the underlying mechanisms of SD during flight and provide a quantitative analysis tool to support flight deck and countermeasure designs.

In order to assist people in making positive changes of problematic behaviour it is necessary to examine how people change and what factors influence the process. Criminal offenders represent a group of individuals who often have difficulty desisting from problematic behaviour and continue to engage in illegal activity. Offenders in provincial correctional institutions were administered questionnaires to determine stage of change and processes utilized as outlined in the Transtheoretical Model (TTM) of change (Prochaska & DiClemente, 1984). Additionally, offenders were asked about their visions of the future using the Possible Selves (PSs) Model (Markus & Nurius, 1986). Taken together, this study looked at the contribution of the PSs Model to our understanding of the TTM, which has been criticized in recent years as lacking therapeutic significance for treatment providers as they guide individuals through the change process. More specifically, this study compares chronic criminals with first time offenders on psychological variables such as readiness for change, vision of possible selves, and hope for the future, as well as on legal variables such as risk for recidivism and institutional behaviour. The results indicate that most offenders acknowledged their behaviour as problematic and some even reported they were actively taking steps to change; however, chronic offenders admitted having less hope than first time offenders. Interestingly, both groups rated similarly on the dimensions of PSs. The outcomes would suggest that research efforts to incorporate other complimentary theories of change into the TTM, like the PSs model, may be helpful for understanding the process of change. While it seems these models may not be useful for predicting institutional behaviour, the data perhaps demonstrates the complexity of criminal behaviour and speaks to the necessity of further research in this population.

abstract: One activity for which philosophers are perhaps best known is having disputes with one another. Some non-philosophers, and increasingly many philosophers, believe that a number of these disputes are silly or misguided in some way. Call such silly or misguided disputes defective disputes. When is a dispute defective? What kinds of defective disputes are there? How are these different kinds of defective disputes different from one another? What does it mean to call a dispute 'merely verbal'? These questions come up for consideration in Part One of this manuscript. In Part Two I examine whether certain disputes in ontology and over the nature of possible worlds are defective in any of the ways described in Part One. I focus mainly on the question of whether these disputes are merely verbal disputes, though I examine whether they are defective in any other ways. I conclude that neither dispute is defective in any of the senses that I make clear in Part One. Moreover, I conclude that even some defective philosophical disputes can be worth consideration under certain circumstances. / Dissertation/Thesis / Ph.D. Philosophy 2011

In exploring the role of social influences in the development of the self, the current study evaluated whether young adults use social comparisons in developing their hoped-for possible selves and, if so, whether their developmental process correlates with self-regulatory processes and positive mental health outcomes. The current study found the following: (1) the domains of hoped-for possible selves among young adults were related to the gender of the social comparison target, (2) the direction of young adults’ social comparison processes (upward or downward) did not significantly influence self-regulatory processes (self-efficacy and outcome expectancy) toward achieving their hoped-for possible selves, (3) strong masculine gender identification related to greater outcome expectancy, while strong feminine gender identification related to both greater self-efficacy and outcome expectancy, and (4) self-efficacy related to less state anxiety, trait anxiety, and depression, while outcome expectancy related only to less trait anxiety. Males and females were found to use traditional gender role identification in forming their hoped-for possible selves.

This study explores the potential relationship between disordered eating and appearance-related possible selves. The sample consisted of 293 female college students (mean age=22). Participants were administered interviews consisting of demographic information, the Possible Selves Interview, the Eating Attitudes Test-26, The Physical Self Description Questionnaire, and the Rosenberg Self-Esteem Scale. More than half of the participants reported an appearance-related possible self (n=154). As expected, disordered eating scores were found to be higher for participants who reported an appearance-related possible self: t(288)=-3.04, p

The metabolism of pure cis- and trans- chlordane was studied in vitro. Microsomal preparations from the livers of male rats induced with cis- or trans-chlordane in feed for ten days were used to metabolize the pure compound corresponding to the inducer. Subsequent extraction, column fractionation and combined gas chromatography-mass spectroscopy resulted in the characterization of four compounds not previously reported from an in vitro system. In addition to the substrate, trans-chlordane extracts contained species with the following molecular weights and empirical formulae: m/e 370, c 10 H 5 Cl 7 , heptachlor; m/e 352, c 10 H 6 0C1 6, a hydroxylated chlordene; and m/e 422, c 10 H 6 0C1 8 , a hydroxylated chlordane. Dichlo rochlo rdene, oxychlordane and 1- chloro- 2 -hydroxychlordene chlorohydrin were also present, With the exception of the hydroxychlordane and heptachlor, cis - chlordane extracts contained all of the metabolites found in the trans-incubates. Additionally, a fully saturated compound m/e 372, c 10 H 7 c1 7, a dihydroheptachlor, was present. The 1, 2-trans-dihydrodiol of heptachlor found in previous in vitro incubates of cis-chlordane was not present in this extract. This information has been incorporated into a proposed route for the biotransformation of the chlordanes that offers an explanation for the observed differences in the metabolism of cis - and trans-chlordane . The pathway is based on the reductive dechlorination of the chlordanes through dihydroheptachlor to dihydrochlordene. Parallel pathways of hydroxylation, desaturation and epoxide formation arise at each of these species and at chlordane itself. The trans-isomer is predominantly desaturated or hydroxylated while the cis-isomer mainly undergoes dehaloge nation.

Possibilities divide into two kinds. Non-qualitative possibilities are distinguished by their connection to specific individuals. For example, the possibility that Napoleon is a novelist is non-qualitative, since it is a possibility for a specific individual, Napoleon. In contrast, the possibility that someone---anyone at all---is a novelist is a qualitative possibility, since it does not depend upon any specific individual. Haecceitism is a thesis about the relation between qualitative and non-qualitative possibilities. In one guise, it holds that some maximal possibilities---total ways the world could be---differ non-qualitatively without differing qualitatively. It would, for example, be only a haecceitistic difference that distinguishes actuality from a maximal possibility where Napoleon and Nefertiti swap all of their qualitative properties and relations. According to this alternative possibility, things are the very same qualitatively, but which individuals occupy which qualitative roles differs: Nefertiti would be a stout conqueror, while Napoleon would be a beautiful consort. This dissertation is an examination of the nature of haecceitism, the arguments in its favor, and the consequences that follow from it. In Chapter One, I distinguish various conceptions of haecceitism and related theses concerning maximal possibilities, possible worlds, the identity of indiscernibles, and non-qualitative properties. In Chapter Two, I develop and defend conceivability arguments for haecceitism in the face of various anti-haecceitist challenges. In Chapter Three, I consider the relation between haecceitism and the Humean approach to plenitude, which aims to characterize the space of possible worlds in terms of combinatorial principles. In Chapter Four, I examine the distinction between qualitative properties like redness and non-qualitative properties like being Napoleon and argue in favor of fundamental non-qualitative properties. In Chapter Five, I present a novel version of non-qualitative counterpart theory, which employs bare particulars to reconcile modal realism and haecceitism. In Chapter Six, I clarify and defend quidditism, the property-theoretic analogue of haecceitism. I conclude in Chapter Seven by defending the modal view of essence.

The present study was conducted to determine the effect of a possible selves intervention on self-regulatory efficacy and exercise behaviour. Participants were 19 men and 61 women (Mage= 21.43, SD = 3.28) who reported exercising less than 3 times per week. Participants were randomly assigned to a control condition, a hoped-for possible selves intervention condition, or a feared possible selves intervention condition. Participants in the hoped-for and feared possible selves conditions completed an activity where they imagined themselves in the future as either healthy, regular exercisers or unhealthy, inactive individuals, respectively. Participants in the control group completed a quiz about physical activity. Measures of self-regulatory efficacy (scheduling, planning, goal-setting, and barrier self-efficacy) were taken immediately before and after exposure to the intervention. Participants who received a possible selves intervention reported greater exercise behaviour 4 weeks post-intervention than participants in the control group (p = .05). Furthermore, planning self-efficacy was found to partially mediate the effect of the possible selves intervention on exercise behaviour. These findings suggest that possible selves may play a role in increasing exercise behaviour among inactive individuals. Future research is warranted to examine the role of possible selves interventions in increasing exercise behaviour and to determine which other variables may mediate this intervention-exercise behaviour relationship. / Thesis / Master of Science (MSc)
