The current longitudinal study evaluated the individual, housing, and neighborhood characteristics predictive of feeling psychologically integrated within one's neighborhood among a population of homeless and vulnerably housed individuals. Participants were recruited at homeless shelters, meal programs, and rooming houses in Ottawa, Canada and participated in three in‐person interviews, each approximately 1 year apart. Prospective and cross‐sectional predictors of psychological integration at Follow‐up 1 and Follow‐up 2 were examined. There were 397 participants at baseline, 341 at Follow‐up 1 and 320 at Follow‐up 2. A hierarchical multiple regression uncovered several significant predictors of psychological integration. The most salient and common predictors were being older, having greater social support, living in high quality housing, and residing in a neighborhood with a positive impact. Implications for service provision and policy advancements are discussed.  相似文献

Confucianism tends to play only a marginal role in current theorizing about justice, which is a global pursuit dominated by Western theory and its strong tendency to assume that justice refers to some substantive conception of distributive, socioeconomic justice. This article examines and compares reconstructions of Confucian justice by Joseph Chan, May Sim, and Fan Ruiping. Each reconstruction makes reference to both classical and modern Western justice theory and thus each involves a comparative approach; indeed, each reconstruction seeks ultimately, in its own distinctive fashion, to present a version of Confucian justice that is comparable with modern Western justice theory. In this article we assess, critically and comparatively, the tertium comparationis and the arguments in each reconstruction. While our analysis does not wholly endorse any of the reconstructions, it shows that there is a richness and vitality to Confucian justice theory that merits proper consideration in justice theory conceived as a truly global and cosmopolitan discipline.  相似文献

In a lifelog, data from various sources are combined to form a record from which one can retrieve information about oneself and the environment in which one is situated. It could be considered similar to an automated biography. Lifelog technology is still at an early stage of development. However, the history of lifelogs so far shows a clear academic, corporate and governmental interest. Therefore, a thorough inquiry into the ethical aspects of lifelogs could prove beneficial to the responsible development of this field. This article maps the main ethically relevant challenges and opportunities associated with the further development of lifelog technologies as discussed in the scholarly literature. By identifying challenges and opportunities in the current debate, we were able to identify other challenges and opportunities left unmentioned. Some of these challenges are partly explained by a blind spot in the current debate. Whilst the current debate focuses mainly on lifelogs held by individuals, lifelogs held by governmental institutions and corporations pose idiosyncratic ethical concerns as well. We have provided a brief taxonomy of lifelog technology to show the variety in uses for lifelogs. In addition, we provided a general approach to alleviate the ethical challenges identified in the critical analysis.  相似文献

People with intellectual disability frequently suffer from epilepsy. Management of epilepsy in this population is particularly challenging because of the different ways of communicating, cognitive impairment, changes in behavior which can be disruptive, the severity of the epilepsy syndrome, the seizure types, and the seizure frequency. Treatment of epilepsy is complicated due to the interaction of the intellectual disability and the behavior as well as behavioral changes caused by the antiepileptic drugs or the change of seizure types or frequency. This article provides the reader with a guidance for managing epilepsy in this particular population and raises important open questions.  相似文献

We argue that the set of humanly known mathematical truths (at any given moment in human history) is finite and so recursive. But if so, then given various fundamental results in mathematical logic and the theory of computation (such as Craig’s in J Symb Log 18(1): 30–32(1953) theorem), the set of humanly known mathematical truths is axiomatizable. Furthermore, given Godel’s (Monash Math Phys 38: 173–198, 1931) First Incompleteness Theorem, then (at any given moment in human history) humanly known mathematics must be either inconsistent or incomplete. Moreover, since humanly known mathematics is axiomatizable, it can be the output of a Turing machine. We then argue that any given mathematical claim that we could possibly know could be the output of a Turing machine, at least in principle. So the Lucas-Penrose (Lucas in Philosophy 36:112–127, 1961; Penrose, in The Emperor’s new mind. Oxford University Press, Oxford (1994)) argument cannot be sound.  相似文献

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not decrease significantly, even for memory intervals of up to 30 s. For other properties, such as stimulus orientation and contrast, however, such “perfect storage” behavior is not found, although the reasons for this difference remain unresolved. Here, we report two experiments in which we investigated the nature of the representation of stimulus contrast in VSTM using spatially complex, two-dimensional random-noise stimuli. We addressed whether information about contrast per se is retained during the memory interval by using a test stimulus with the same spatial structure but either the same or the opposite local contrast polarity, with respect to the comparison (i.e., remembered) stimulus. We found that discrimination thresholds got steadily worse with increasing duration of the memory interval. Furthermore, performance was better when the test and comparison stimuli had the same local contrast polarity than when they were contrast-reversed. Finally, when a noise mask was introduced during the memory interval, its disruptive effect was maximal when the spatial configuration of its constituent elements was uncorrelated with those of the comparison and test stimuli. These results suggest that VSTM for contrast is closely tied to the spatial configuration of stimuli and is not transformed into a more abstract representation.  相似文献

Contemporary philosophers often purport to ‘borrow’ or ‘refute’ claims made by past philosophers. In doing so they contravene a contextualist methodological prohibition once defended by Quentin Skinner in his seminal paper “Meaning and Understanding in the History of Ideas”. Skinner's methodology has been much debated by theorists of textual meaning and interpretation, and yet the precise nature of the logical path from his premises to his prohibitory conclusion remains elusive. This paper seeks to refute two of the most promising variants of an argument for his methodological prohibition on ‘refutation’, one of which draws on his appeal to Wittgenstein's conception of ‘meaning as use’, and the other of which draws on his appeal to speech act theory.  相似文献

This study explored the differences in perceived unit cohesion, trauma symptoms, depression symptoms, and anxiety symptoms controlling for childhood trauma, based on attachment style in US military veterans. Previous studies have reported that higher levels of military unit cohesion, bonding through the social relationships between service members and their larger units, and secure attachment, are negatively associated with trauma symptoms, depression symptoms, and anxiety symptoms in veterans. This study examined mental health distress symptoms as well as military unit cohesion across attachment styles. Results suggest mean differences in trauma symptoms, depression symptoms, and anxiety symptoms across attachment styles. However, there was no difference in perceived unit cohesion across the four attachment styles. Those using fearful-avoidant attachment styles reported the highest mean trauma, depression, and anxiety symptoms followed by those using a dismissing-avoidant attachment style. Those using a secure attachment style reported the least mean trauma, depression, and anxiety symptoms. Implications for assessing and treating avoidant type attachment styles are discussed.  相似文献
