In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other reference persons can influence human–animal interaction at different levels and over different periods of time. In this study, we investigated human-directed behaviour in the ‘unsolvable task’ paradigm in two groups of domestic goats (Capra aegagrus hircus). One group was positively handled and habituated to a plastic box by the experimenter to retrieve a food reward, while the other group only received standard husbandry care and was habituated to the box without human assistance. In the unsolvable task, the lid was fixed to the box, with the reward inaccessible to the subjects. The goats were confronted with the unsolvable task three times. We observed no difference between the two groups regarding gaze and contact alternations with the experimenter when confronted with the task they cannot solve by themselves. The goats did not differ in their expression rates of both gaze and contact alternations over three repetitions of the unsolvable task; however, they showed earlier gaze and contact alternations in later trials. The results do not support the hypothesis that short-term positive handling or task-specific training by humans facilitates human-directed behaviour in goats. In contrast, standard husbandry care might be sufficient to establish humans as reference persons for farm animals in challenging situations. 相似文献

The purpose of this study is estimate a model that contains five hypotheses: (1) people who attend worship services more often will receive more spiritual support; (2) individuals who receive more spiritual support will be more humble; (3) people who are more humble will be more likely to forgive; (4) people who are more forgiving will find a greater sense of meaning in life; and (5) a greater sense of meaning in life will be associated with better self-rated health. Data from a nationwide survey of adults age 18 and older (N = 1,744) provide support for each hypothesis. 相似文献

Role-specific feelings of control and mortality 总被引:4,自引:0,他引:4
The purpose of this study is to examine the impact of 2 different measures of personal control on mortality in late life. The 1st reflects control over the 3 roles that are most important to elderly study participants. The 2nd is a global measure that assesses control over life as a whole. Data provided by a nationwide survey of older adults (N = 884) indicate that feelings of control over the single most important role significantly reduce the odds of dying. In contrast, control over the 2nd and 3rd most important roles are not related to mortality, nor are feelings of control over life as a whole. The theoretical implications of these findings are discussed. 相似文献

The purpose of this study is to see if there are age differences in the relationship between chronic financial strain, emotional support, and life satisfaction among people aged 65 and older. Data from a nationwide survey of older people (N = 1,518) indicate that emotional support tends to reduce the noxious effects of economic problems on life satisfaction for the sample as a whole. However, the findings further reveal that the potential benefits of emotional support arise primarily among the oldest-old. In contrast, emotional support does not offset the negative effects of financial strain on life satisfaction among the young-old. 相似文献

A descriptive epidemiology of lifetime trauma and the physical health status of older adults 总被引:1,自引:0,他引:1
Three issues are evaluated in this study. The 1st involves examining the relationship between exposure to trauma over the life course and physical health status in old age. The 2nd has to do with seeing whether the relationship between trauma and health varies across 3 cohorts of older adults: the young-old (ages 65-74), the old-old (ages 75-84), and the oldest old (age 85 and over). The 3rd issue involves seeing whether the age at which a trauma was encountered is related to health in late life. Data from a nationwide survey of older people (N=1,518) reveal that trauma is associated with worse health. Moreover, the young-old appear to be at greatest risk. Finally, data suggest that trauma arising between the ages of 18 and 30 years, as well as ages 31 to 64 years, has the strongest relationship with current health. 相似文献

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; 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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.
