In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms of which represent physical processes. Usually, this category is taken to be at least compact closed, and more often, dagger compact, enforcing a certain self-duality, whereby preparation processes (roughly, states) are interconvertible with processes of registration (roughly, measurement outcomes). This is in contrast to the more concrete “operational” approach, in which the states and measurement outcomes associated with a physical system are represented in terms of what we here call a convex operational model: a certain dual pair of ordered linear spaces–generally, not isomorphic to one another. On the other hand, state spaces for which there is such an isomorphism, which we term weakly self-dual, play an important role in reconstructions of various quantum-information theoretic protocols, including teleportation and ensemble steering. In this paper, we characterize compact closure of symmetric monoidal categories of convex operational models in two ways: as a statement about the existence of teleportation protocols, and as the principle that every process allowed by that theory can be realized as an instance of a remote evaluation protocol—hence, as a form of classical probabilistic conditioning. In a large class of cases, which includes both the classical and quantum cases, the relevant compact closed categories are degenerate, in the weak sense that every object is its own dual. We characterize the dagger-compactness of such a category (with respect to the natural adjoint) in terms of the existence, for each system, of a symmetric bipartite state, the associated conditioning map of which is an isomorphism. 相似文献

Franz Kafka's (1967/1999) Letters to Felice is instructive for the therapist/reader because it provides a first-person narrative of Kafka's immersion in a fundamentally relational-experiential process. It is argued that the underlying We of Kafka's letters implies that their correspondence expressed and constituted their relationship. Significant aspects of his experiencing are discussed from a person-centered perspective. It is argued that his experiences were initially subceived prior to awareness, in the moment, bodily felt, and process-like. The parallels that exist between the experience of reading Letters to Felice and being in a person-centered therapeutic relationship are discussed. Both endeavors are experiential and phenomenological, and from a contemporary person-centered perspective, are based upon a refinement of Carl Rogers’ original formulation. 相似文献

Most clinical research assumes that modulation of facial expressions is lateralized predominantly across the right-left hemiface. However, social psychological research suggests that facial expressions are organized predominantly across the upper-lower face. Because humans learn to cognitively control facial expression for social purposes, the lower face may display a false emotion, typically a smile, to enable approach behavior. In contrast, the upper face may leak a person’s true feeling state by producing a brief facial blend of emotion, i.e. a different emotion on the upper versus lower face. Previous studies from our laboratory have shown that upper facial emotions are processed preferentially by the right hemisphere under conditions of directed attention if facial blends of emotion are presented tachistoscopically to the mid left and right visual fields. This paper explores how facial blends are processed within the four visual quadrants. The results, combined with our previous research, demonstrate that lower more so than upper facial emotions are perceived best when presented to the viewer’s left and right visual fields just above the horizontal axis. Upper facial emotions are perceived best when presented to the viewer’s left visual field just above the horizontal axis under conditions of directed attention. Thus, by gazing at a person’s left ear, which also avoids the social stigma of eye-to-eye contact, one’s ability to decode facial expressions should be enhanced. 相似文献

Abstract The use of shock tactics to motivate people to learn more about AIDS and to take appropriate protective action characterised the approach adopted by the national health authorities in Australia during 1987. The rationale underlying this approach is critically examined, particularly in the light of results obtained from surveys of community concern and knowledge about AIDS in the state of South Australia before the campaign and after it had been in progress for some five months. Contrary to expectations no significant increases in either personal or social concern were found; in fact, among older respondents personal concern had decreased significantly. Levels of knowledge about AIDS, in general, remained unchanged, apart from an increase in acceptance of the safety of blood transfusions from a very low to a somewhat higher level. Among a minority of respondents (29%) who approved of the campaign and also believed they had been influenced by it, personal and social concern about AIDS, but not knowledge, was significantly greater than among others. The view that fear-inducing techniques can be used to bring about increases in knowledge about AIDS was not supported, although some positive effects on the social attitudes of respondents most affected by the campaign are suggested. 相似文献

ObjectivesThe purpose of this investigation was to examine adolescent athletes' injury recovery and return-to-sport experiences. Given previous research highlighting competence, autonomy, and relatedness concerns among returning athletes (Podlog & Eklund, 2006), we sought to examine the extent to which basic psychological needs theory (BPNT: Ryan & Deci, 2007) could be used as framework for interpreting the research findings.DesignA qualitative design was employed in the present investigation.MethodEleven Australian athletes (M age = 15.3) who had incurred a range of severe injuries (e.g., anterior cruciate ligament tears, shoulder dislocations) were interviewed on 2–3 occasions (n = 27 interviews) spanning an 11-month period.ResultsAnalysis of the data revealed the following four key themes: (a) injury stress, (b) coping strategies, (c) experiences with social support, and (d) recovery outcomes. Injury stress provides insights into a range of stressors and strain responses reported by the adolescents across the recovery phases, while the theme on coping highlights the specific strategies used to maintain motivation, reduce uncertainties associated with the injury experience, and to keep focused on future athletic attainment. The third theme, experiences with social support, considers the transactions the adolescents held with members of their social network throughout their recovery. The final theme, recovery outcomes, describes participant perceptions of a successful/unsuccessful recovery and stress-related growth.ConclusionsResults suggest that competence and relatedness issues highlighted in BPNT may be relevant in exploring adolescent athletes' injury experience. Somewhat less evidence for the autonomy dimension of BPNT was apparent in adolescent comments. 相似文献

A foundational belief of monotheistic religions is that God acts in the world. In this paper, the case is made that divine action has its origins in the molecular world. Within a metaphysical framework of process thought, a hypothesis is constructed in which God's action in the world, God's ‘initial aim’ for all actualities, is divine motivation of chemical becoming. 相似文献

ABSTRACT The evaluation of visitor flow within a museum or exhibition has been a topic of interest for decades with several research approaches taken over the years. Direct observation or visitor tracking during museum occupancy is the most popular technique, but it generally requires substantial amounts of time and financial resources. An alternative approach to direct observation—visitor self-mapping—is presented using data obtained from 2 short-term, small-budget evaluations of a world-class collection museum. Results show that self-mapping provides usable data with more than 90% of maps having tracking data for the entire museum. Maps varied in the amount of detail, but more than 60% of visitors provided details beyond what was required. In Study 1, movement patterns, sweep rate indices, and timing data suggest that the mapping data accurately reflected the visitor experience. Study 2 directly paired the self-mapping method used in Study 1 with unobtrusive behavioral observations to address the reliability and validity of the new approach. A discussion compares the relative costs and benefits of the new approach with more conventional direct observation techniques and provides directions for future research. 相似文献

Psychological trauma, stress, childhood abuse, neglect, and loss are mentioned as important features or risk factors for mental disorders in 15 out of 19 sections of the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]). This means that, according to the DSM–5, trauma and stress are relevant themes throughout the mental health field, not solely an area of subspecialty. Despite the recognition of the widespread role of trauma and stress in the DSM–5, there are inconsistencies in the discussion of trauma, including its relationship to anger and aggression, that should be corrected in future editions of the manual. 相似文献

Holistic processing is a hallmark of face processing. There is evidence that holistic processing is strongest for faces at identification distance 2–10 metres from the observer. However, this evidence is based on tasks that have been little used in the literature and that are indirect measures of holistic processing. We use the composite task—a well validated and frequently used paradigm—to measure the effect of viewing distance on holistic processing. In line with previous work, we find a congruency x alignment effect that is strongest for faces that are close (2 m equivalent distance) than for faces that are further away (24 m equivalent distance). In contrast, the alignment effect for same trials, used by several authors to measure holistic processing, produced results that are difficult to interpret. We conclude that our results converge with previous findings providing more direct evidence for an effect of size on holistic processing. 相似文献
