Suicide in later life is a growing public health concern that is expected to increase as the baby boom generation reach late adulthood. In the general population, older adults have rates of suicide that are higher than any other age group. The rate of suicide is particularly higher for older men. In Canada, older men between 80 and 84 years have rates of suicide approximately six times greater than older women the same age. Older adults living in the community are a sub-set of the population that are at high risk for suicide yet are not typically a focus of suicide research. As a result they remain hidden from the view of mental health promotion and suicide prevention programs until a decline in mental status brings them to the attention of formal mental health care services. Improving our understanding of suicide in later life particularly among community-residing older men can inform suicide prevention strategies. To improve this understanding, the goals of this research were three-fold: to comprehensively describe the sociodemographic and clinical characteristics of community residing older adults who have experienced suicide-related behaviour; to describe the rates, risk and protective factors, and predictors of suicide-related behaviour among this population; and to compare these findings to a subpopulation of community-residing older adults with neurological conditions. To achieve these aims, this research utilized a secondary data analysis approach using health information from multiple linked datasets. The Canadian Institute of Health Information (CIHI) performed record linkages between Ontario hospital administrative data (Discharge Abstract Database, National Ambulatory Care Reporting System, and Ontario Mental Health Reporting System) and Ontario home care data (Home Care Reporting System). Home care data are sourced from the Resident Assessment Instrument–Home Care (RAI-HC) Assessment Instrument, the provincially mandated assessment tool used to identify the strengths, preferences and needs of all long-stay home care clients. The RAI-HC contains over 350 items across a wide range of domains including health, functional status and resource use. Linkages of these data records between home care and hospital sectors enabled the prospective examination of community-residing older adults with recent suicide-related behaviour. This is one of the first national and international studies to use the RAI-HC to examine older home care clients with experiences of suicide-related behaviour. The study samples consisted of Ontario home care clients aged 60 years or older assessed with the RAI-HC between April 2007 and September 2010. Clients’ initial RAI-HC assessment was examined followed by corresponding hospital records for suicide-related behaviour (N = 222,149). The prevalence of suicide-related behaviour for the sample was 1.01% (n=2,077) with higher rates for older men than women. Rates were examined across geographic regions of Ontario. Descriptive analyses demonstrated that older adults with suicide-related behaviour had more indicators of psychiatric distress (including cognitive impairment) and psychosocial dysfunction than the general home care population. Multivariate analyses showed significant effects for age and gender in the prediction of suicide-related behaviour after adjusting for risk and protective covariates. Tangible areas for intervention were revealed that may reduce future suicide risk such as managing alcohol use and dependence, managing pain, increasing positive social relationships, and reducing social isolation. Time-to-event analysis supported the multivariate regression findings. Analyses of two subpopulations of older adults with neurological conditions (dementia and Parkinson’s disease) demonstrated marked differences in suicide risk and protective factors compared to the general home care population. Findings suggest that a one-size-fits-all approach to suicide prevention and intervention is not appropriate for persons with these conditions, as their specific risk and protective factors need to be taken into consideration. This study based on provincial data covering the home care sector in Ontario defined high risk groups of older adults and provided evidence for risk and protective factors associated with suicide-related behaviour. Findings point to several areas that should be assessed by home care professionals to reduce risk in the older home care client population. This multi-dimensional profile of high risk older adults will assist in initiating a policy dialogue regarding the need for targeted suicide prevention strategies in Ontario’s home care sector.

Sripada and Konrath (forthcoming) use Structural Equation Modeling techniques to provide empirical evidence for the claim that implicit and automatic inferences about people’s dispositions, and not normative judgments, are the driving cause behind the pattern of folk judgments of intentional action in Knobe’s (2003a) chairman case. However, I will argue that their evidence is not as strong as they claim due to the potential of methodological and statistical problems with the way they tested their model. After correcting for these problems, I show that even after accounting for the role of dispositional inferences, normative judgments are still playing a significant role in folk judgments of intentional action.

This thesis examines current radical liberal Christian activism in the Southern United States through focusing upon a particular intentional community located in Atlanta, Georgia, The Open Door Community. Through praxis and reflection, this community has developed its own unique practice and theology that I have termed “Liberation Gospel.” This thesis analyzes and describes a unique community in order to understand where the community succeeds, and where it does not, in putting its theological beliefs into practice. This very liberal community does not distinguish between their politics and their theology.

In this dissertation, I examine the role that intentional descriptions play in our scientific study of the mind. Behavioural scientists often use intentional language in their characterization of cognitive systems, making reference to “beliefs”, “representations”, or “states of information”. What is the scientific value gained from employing such intentional terminology? I begin the dissertation by contrasting intentional descriptions with mechanistic descriptions, as these are the descriptions most commonly used to provide explanations in the behavioural sciences. I then examine the way that intentional descriptions are employed in various scientific contexts. I conclude that while mechanistic descriptions characterize the underlying structure of systems, intentional descriptions allow us to generate predictions of systems while remaining agnostic as to their mechanistic underpinnings. Having established this, I then argue that intentional descriptions share much in common with statistical models in the way they characterize systems. Given these similarities, I theorize that intentional descriptions are employed within scientific practice as a particular type of phenomenological model. Phenomenological models are used to study, characterize, and predict the phenomena produced by mechanistic systems without describing their underlying structure. I demonstrate why such models are integral to our scientific discovery, and understanding, of the mechanisms that make up the brain. With my account on the table, I then look back at previous accounts of intentional language that philosophers have offered in the past. I highlight insights that each brought to our understanding of intentional language, and point out where each ultimately goes astray. I conclude the dissertation by examining the ontological implications of my theory. I demonstrate that my account is compatible with versions of both realism, and anti-realism, regarding the existence of intentional states.

Ancient Egyptian belief in an afterlife influenced a wide variety of architectural and art forms. In the Eighteenth Dynasty at Thebes, non-royal officials were equipped with tombs that were decorated to aid in their everlasting sustenance and rebirth in the hereafter as well as commemorate them to living visitors. Part of this continuation of life involved the participation of the funerary cult of the deceased, as well as the prompting of visitors to speak the owner’s name and provide the required offerings—allowing (and encouraging) public access to the decorated tomb chapel. However, some visitors wished to harm the deceased’s perpetuation of life. In order to obliterate the memory of the tomb owner in the minds of the living and his existence in the afterlife, enemies carefully hacked the tomb owner’s images out of the decoration program in an act of damnatio memoriae. The owners of Theban tombs 66, 75, and 76 fell victim to this intentional destruction by contemporary hands.

Multicarrier modulation is a transmission technique that is quite convenient for high data rates in wireless communication. Information symbols are partitioned and parallelly sent over multiple narrowband subchannels. Pulse shaping filters are critically important in multicarrier modulation for determining the characteristics of signal in time and frequency domains. In this thesis, we propose a new pulse shaping approach for multicarrier schemes to increase spectral efficiency in multi-user scenarios. Conventionally, the time-frequency lattice and the prototype filter are designed considering the worst-case of time-varying multipath channel. However, this approach ignores to make use of multi-user diversity and leads to excessive spacings between successive symbols in time and frequency. Unlike the prevalent methods, we investigate user-based filter utilization considering the wireless channel of each user individually to prevent over-design and improve spectral efficiency. Also, this approach is implemented in a denser time-frequency lattice design. Symbols are allowed to be overlapped (depending on time-frequency dispersion of their individual channels) as long as the signal-to-interference ratios (SIRs) observed by all users are kept above a certain level. Employing user-specific filters to enhance SIR of the user exposed to the most interference provides more overlapping flexibility. Therefore, further improvement in spectral efficiency is achieved in our wireless communication system design.

In the wake of the Great Recession of 2008, the ‘new normal’ left many Americans deflated after losing their financial savings and general confidence in the political system. There is a growing movement saying the traditional path to the American Dream is no longer satisfying. From coast to coast families are moving from sleepy towns to so-called ‘intentional communities’ in search of alternatives. They are building new lives in spiritual enclaves, nudist havens, eco-wonderlands and other unorthodox societies while seeking like-minded souls and a better way of making a living. Although they don’t often reflect the traditional lifestyle of most citizens, they do represent the widespread frustration with the status quo. The United States has long been a safe haven for these nonconformists and continues to attract those seeking escape from the mainstream each year. Intentional communities throughout Texas and the U.S. are flourishing despite harsh economic times elsewhere. This report documents daily life in three intentional communities during 2011 and 2012, all focused on achieving their individual goals of environmental protection, building community bonds, and achieving spiritual enlightenment. / text

It is widely acknowledged that an agent is doing A intentionally only if she knows she is doing A. It has proved difficult, however, to reconcile two natural thoughts about this knowledge. On the one hand, the agent seems to know what she is doing immediately, simply by doing it. Her knowledge seems to rely upon no evidence, and indeed to rest upon no specifiable epistemic basis at all. On the other hand, the agent can be wrong about what she is doing; she is fallible. The difficulty is to see how an agent can be wrong about her action if her knowledge of it is immediate. My dissertation provides an account of the agent’s knowledge of her own actions that reconciles these natural, but apparently conflicting thoughts. In the face of this difficulty, many philosophers distinguish two objects of knowledge in action: the object of immediate knowledge, which is supposed to be something interior, and what the agent actually does, which is known only mediately. I argue that this two-factor framework is unacceptable, since it cannot account for the insight which motivated the study of intentional action via the agent’s knowledge of these actions: that it is in virtue of this specific way of knowing that the agent is the agent of her intentional actions. Instead, I defend a view on which acting intentionally itself, with no need for further epistemic work, is a way of knowing what actually happens. This account of knowledge in action also allows me to clarify how this knowledge is necessarily related to our capacity for agency. I argue that the rational capacities that are drawn on in figuring out what to do here and now are the very source of both the action’s taking place, and the agent’s knowledge of her actions without evidence. Since the agent’s knowledge is the result of the very same reasoning that brings about the action, it is practical, and the agent’s having it is the mark of her practical rationality at work and her being the knowingly efficacious author of the action. / Philosophy

The cognitive models that research on conceptual change has generated have been the subject of criticism, suggesting that these reflect an unrealistic view of learning as an overly “cold” and isolated process. Accordingly, representatives of this criticism suggest that research on conceptual change should investigate to what extent the cold cognition relates to “warm” affective constructs. In the present thesis, the warmth is not considered as prior to conceptual change, but is inferred from the very process of conceptual change itself. The aim is to investigate and describe how this warmth – in terms of normativity – is expressed in conceptual change and how individuals, in these processes, emerge as subjects in their interchange with the environment. This is done by exploring what students do when they make meaning of gender and nation in interviews and exam papers. The results show that the students mainly relate to two different norm-systems, including six normative aspects of conceptual change. The first system includes the goal to challenge or emancipate, the means to problematize, and engagement in the interviews or exams. Furthermore, it includes critical theory as an ideal, social structures and power as values, and me as a social being and actions as part of a tradition as what to make meaning of. The second system includes the goal to preserve, the means to claim how it “is”, and engagement in the interviews or exams. Furthermore, it includes psychological/biological reductionism as an ideal, essences and a natural order as values, and me as an individual and actions as an outcome of intentions as what to make meaning of. By understanding what the students do as interfering with these normative aspects, it becomes possible to understand them as negotiating norms that are brought to the fore. With this, “coldness” appears to be a misleading epithet of conceptual change. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: Submitted.
