Both traditional accounts of hope and some of their recent critics analyze hope exclusively in terms of attitudes that a hoper bears towards a hoped-for prospect, such as desire and probability assignment. I argue that all of these accounts misidentify cases of despair as cases of hope, and so misconstrue the nature of hope. I show that a more satisfactory view is arrived at by noticing that in addition to the aforementioned attitudes, hope involves a characteristic attitude towards an external factor, on whose operation the hoper takes the prospect's realization to depend causally.  相似文献

David Makinson has argued that the compelling character of counterexamples to the Recovery Condition on contraction is due to an appeal to justificational structure. In “naked theories” where such structure is ignored or is not present, Recovery does apply. This note attempts to show that Makinson is mistaken on both counts. Recovery fails when no appeal is made to justificational structure. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Many parents report that their values are influenced by their children. However, few studies provide direct evidence regarding child–parent value transmission. We review this evidence and propose five main processes of child influence: (i) Passive child influences, causing change in parental values by the mere presence or development of children; (ii) Active child influences, due to children directly attempting to influence their parents’ opinions or providing parents with relevant information; (iii) Differentiation, the emergence of a distinction between parents’ own personal values and their socialization values; (iv) Reciprocal influences; in which parents’ and children’ influences are intertwined; and (v) Counter‐influences, in which parental values change in a direction opposite to that of children's values. A study on child influence illustrates some of these processes. The roles of migration, aging, and parent and child characteristics in child‐to‐parent influences are discussed.  相似文献

Most solutions to the sorites reject its major premise, i.e. the quantified conditional . This rejection appears to imply a discrimination between two elements that are supposed to be indiscriminable. Thus, the puzzle of the sorites involves in a fundamental way the notion of indiscriminability. This paper analyzes this relation and formalizes it, in a way that makes the rejection of the major premise more palatable. The intuitive idea is that we consider two elements indiscriminable by default, i.e. unless we know some information that discriminates between them. Specifically, following Rough Set Theory, two elements are defined to be indiscernible if they agree on the vague property in question. Then, a is defined to be indiscriminable from b if a is indiscernible by default from b. That is to say, a is indiscriminable from b if it is consistent to assume that a and b agree on the relevant vague property. Indiscernibility by default is formalized with the use of Default Logic, and is shown to have intuitively desirable properties: it is entailed by equality, is reflexive and symmetric. And while the relation is neither transitive nor substitutive, it is “almost” substitutive. This definition of indiscriminability is incorporated into three major theories of vagueness, namely the supervaluationist, epistemic, and contextualist views. Each one of these theories is reduced to a different strategy dealing with multiple extensions in Default Logic, and the rejection of the major premise is shown to follow naturally. Thus, while the proposed notion of indiscriminability does not solve the sorites by itself, it does make the unintuitive conclusion of many of its proposed solutions—the rejection of the major premise—a bit easier to accept.  相似文献

A new measure for reliability of a rating scale is introduced, based on the classical definition of reliability, as the ratio of the true score variance and the total variance. Clinical trial data can be employed to estimate the reliability of the scale in use, whenever repeated measurements are taken. The reliability is estimated from the covariance parameters obtained from a linear mixed model. The method provides a single number to express the reliability of the scale, but allows for the study of the reliability’s time evolution. The method is illustrated using a case study in schizophrenia. The authors are grateful to J&J PRD for kind permission to use their data.

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.  相似文献

Background: Transgender and gender nonconforming (TGNC) individuals encounter a variety of minority stressors that have yet to be fully articulated or explored within the research literature. The purpose of this study is to better understand internalized stigma—the experience of accepting and internalizing negative social messages and experiences about one's identity—an underexplored minority stressor for TGNC people.

Method: We conducted in-depth interviews with 30 diverse TGNC participants using consensual qualitative research (CQR) methodology.

Results: Following data saturation and analysis, six distinct themes emerged across participants: (1) TGNC identities are regarded negatively by society; (2) social messages are perceived as originating from the media and religious ideology; (3) TGNC individuals report emotional distress; (4) negative self-perceptions in response to social messages; (5) TGNC individuals report resilience processes in response to negative social messages; and (6) social messages are perceived generally to differentially impact TGNC people of color.

Conclusion: Findings highlight the common experience of encountering social marginalization for TGNC individuals. Structural interventions that target pervasive sociocultural messages regarding TGNC identities are warranted.  相似文献

Prosocial behavior is important for the functioning of society. This study investigates the extent to which environment shared by family members, nonshared environment, and genetics account for children's prosocial behavior. The prosocial behavior of twins (9,424 pairs) was rated by their parents at the ages of 2, 3, 4, and 7 and by their teachers at age 7. For parent ratings, shared environmental effects decreased from .47 on average at age 2 to .03 at age 7, and genetic effects increased from .32 on average to .61. The finding of weak shared environmental effects and large heritability at age 7 was largely confirmed through the use of teacher ratings. Using longitudinal genetic analyses, the authors conclude that genetic effects account for both change and continuity in prosocial behavior and nonshared environment contributes mainly to change.  相似文献

Children with anxiety disorders experience high rates of sleep-related problems, with co-sleeping and resistance to sleeping independently being among the more frequent problems reported. Although extinction-based behavioral sleep interventions have repeatedly been shown to be highly effective for treating bedtime resistance, the primary obstacle to their implementation is parent discomfort with these procedures. The bedtime pass intervention was developed to minimize extinction bursts when implementing extinction procedures for childhood sleep problems. Several studies have found this intervention to be effective for treating bedtime resistance behaviors, but not co-sleeping specifically, in nonclinical samples of children. The current paper describes the use of a modified bedtime pass procedure to target problematic co-sleeping and related bedtime resistance behaviors in two children with anxiety disorders who presented for treatment at an outpatient pediatric anxiety specialty clinic. A changing criterion, single subject methodology was used to evaluate the effectiveness of this procedure. Data indicate that both children were able to transition from co-sleeping with parents every night, to sleeping independently, with relatively limited need for contact with parents at night during the intervention. These findings extend the data for the bedtime pass procedure to both co-sleeping and children with anxiety disorders. Clinical implications of these findings are discussed given the limited guidance for treating comorbid sleep problems in anxious children. Strengths and limitations of the data being drawn from a clinical treatment setting are also discussed.  相似文献
