Schrödinger logics

Schrödinger logics are logical systems in which the principle of identity is not true in general. The intuitive motivation for these logics is both Erwin Schrödinger's thesis (which has been advanced by other authors) that identity lacks sense for elementary particles of modern physics, and the way which physicists deal with this concept; normally, they understandidentity as meaningindistinguishability (agreemment with respect to attributes). Observing that these concepts are equivalent in classical logic and mathematics, which underly the usual physical theories, we present a higher-order logical system in which these concepts are systematically separated. A classical semantics for the system is presented and some philosophical related questions are mentioned. One of the main characteristics of our system is that Leibniz' Principle of the Identity of Indiscernibles cannot be derived. This fact is in accordance with some authors who maintain that quantum mechanics violates this principle. Furthermore, our system may be viewed as a way of making sense some of Schrödinger's logical intuitions about the nature of elementary particles.The authors very much would like to thank the anonymous referee for his quite interesting suggestions, which contributed significantly to improve the paper.Presented byJan Zygmunt;     

An economical modification of radial immunodiffusion for the determination of immunoglobulins in the cerebrospinal fluid]

In a total of fifty cerebrospinal fluids, such immunoglobulins as IgG, IgA, and IgM were quantitatively determined in a parallel manner on LC partigen plates and on slides (SEVAC set of means of testing). The comparability of the two methods of test proved excellent with good precision. The sensitivity of IgA determination on slides was made higher, the measurability of all precipitates was improved, and the economic advantage increased by cutting the cost of one determination fifteen times.     

The institutionalization of community interventions in Chile: characteristics and contradictions

A critical analysis of the consequences of successive institutionalization of community intervention in Chile is presented. This analysis is based on research of current community interventions in Chile, whose results are compared with Chilean community practice from previous historical periods. Chilean community intervention was formerly practiced out of governmental institutions and universities and was sustained primarily by foreign agencies and ecclesiastical institutions. Nowadays, with the return to democracy, the vast majority of community intervention programs are financed, partially or totally, by means of governmental resources. This institutionalization of community interventions has had consequences worthy of critical analysis: an increase in the number and stability of intervention programs; and also negative consequences for intervention goals, definition of target groups, and intervention practices. Dilemmas, such as assistance vs. promotion or adaptation vs. social change, have arisen. These dilemmas show the contradictions of a Community Psychology, which has left behind the position of institutional marginality to form part of Chilean society's normal psychosocial care. They also show the need for a paradigm shift from a critical view of the social world to a constructionist one.     

Church-Based Social Support and Religious Coping

The purpose of this study is twofold: to explore the nature of church-based social support, and to see whether support received in religious settings is related to the use of religious coping methods. The data come from a nationwide survey of members of the Presbyterian Church USA. Three dimensions of religious support are examined in detail: emotional support from church members, spiritual support from church members, and emotional support from the pastor. These dimensions of support are used to evaluate an issue that has been largely overlooked in the literature—the relationship between religious support and religious coping. The findings reveal that people are especially inclined to use positive religious coping responses when they receive spiritual support from church members. Even though emotional support from the pastor also increases the use of religious coping methods, the relationship is not as strong. Finally, emotional support from church members has no effect.     

Quantum sortal predicates

Sortal predicates have been associated with a counting process, which acts as a criterion of identity for the individuals they correctly apply to. We discuss in what sense certain types of predicates suggested by quantum physics deserve the title of ‘sortal’ as well, although they do not characterize either a process of counting or a criterion of identity for the entities that fall under them. We call such predicates ‘quantum-sortal predicates’ and, instead of a process of counting, to them is associated a ‘criterion of cardinality’. After their general characterization, it is discussed how these predicates can be formally described. To Patrick Suppes on his 80th birthday.     

Emotion und Psychotherapie

Considering the fact that all psychic disturbances are emotional disturbances as well, we develop based on our research on the modular structure of the emotional system a systematisation of the disturbance-specific concatenation of these modules within the patient’s social relationships. Subsequently, we discuss treatment possibilities and contraindications for each clinical empirically validated constellation. We describe a fundamental mechanism of affect induction keeping the disturbances alive and transporting them to the next generation. We conclude in stating that treatment recommendations focusing on a standard algorithm of handling the emotions system fail because there is no general indication for such enterprises.     

Religious Doubt and Mental Health Across the Lifespan

The current study examined the connections among religious doubt, mental health, and aging in a nationwide sample of individuals 18 years and older (N = 1629). Findings indicate that that religious doubt emerging from the recognition of suffering and evil in the world has a deleterious impact on mental health. Results also show that as people grow older, religious doubts continue to be associated with psychopathology, but the magnitude of this association becomes weaker across age categories. In other words, the impact of doubt on mental distress declines as one ages. These effects were found across various measures of mental distress, including depression, general anxiety, interpersonal sensitivity, paranoia, hostility, and obsessive-compulsive symptoms. Findings are explored within the context of psychosocial development and the experiential trajectory of religious maturity.     

Trust-Based Prayer Expectancies and Health Among Older Mexican Americans

This study assesses the health-related effects of trust-based prayer expectancies, which reflect the belief that God answers prayers at the right time and in the best way. The following relationships are evaluated in our conceptual model: (1) older Mexican Americans who attend worship services more often tend to develop a closer relationship with God; (2) people who feel close to God will be more likely to develop trust-based prayer expectancies; (3) people who endorse trust-based prayer expectancies will have greater feelings of self-esteem; and (4) higher self-esteem is associated with better self-rated health. The data support each of these relationships.     

Assessing Stability and Change in a Second-Order Confirmatory Factor Model of Meaning in Life

Research indicates that meaning in life is an important correlate of health and well-being. However, relatively little is known about the way a sense of meaning may change over time. The purpose of this study is to explore two ways of assessing change in meaning within a second-order confirmatory factor analysis framework. First, tests are conducted to see if the first and second-order factor loadings and measurement error terms are invariant over time. Second, a largely overlooked technique is used to assess change and stability in meaning at the second-order level. Findings from a nationwide survey reveal that the first and second-order factor loadings are invariant of time. Moreover, the second-order measurement error terms, but not the first-order measurement error terms, are invariant, as well. The results further reveal that standard ways of assessing stability mask significant change in meaning that is due largely to regression to the mean.     

How dogs scan familiar and inverted faces: an eye movement study

Faces play an important role in communication and identity recognition in social animals. Domestic dogs often respond to human facial cues, but their face processing is weakly understood. In this study, facial inversion effect (deficits in face processing when the image is turned upside down) and responses to personal familiarity were tested using eye movement tracking. A total of 23 pet dogs and eight kennel dogs were compared to establish the effects of life experiences on their scanning behavior. All dogs preferred conspecific faces and showed great interest in the eye area, suggesting that they perceived images representing faces. Dogs fixated at the upright faces as long as the inverted faces, but the eye area of upright faces gathered longer total duration and greater relative fixation duration than the eye area of inverted stimuli, regardless of the species (dog or human) shown in the image. Personally, familiar faces and eyes attracted more fixations than the strange ones, suggesting that dogs are likely to recognize conspecific and human faces in photographs. The results imply that face scanning in dogs is guided not only by the physical properties of images, but also by semantic factors. In conclusion, in a free-viewing task, dogs seem to target their fixations at naturally salient and familiar items. Facial images were generally more attractive for pet dogs than kennel dogs, but living environment did not affect conspecific preference or inversion and familiarity responses, suggesting that the basic mechanisms of face processing in dogs could be hardwired or might develop under limited exposure.
