Academic discussion of pornography is generally restricted to issues arising from the depiction of adults. I argue that child-pornography is a more complex matter, and that generally accepted moral judgements concerning pornography in general have to be revised when children are involved. I look at the question of harm to the children involved, the consumers, and society in general, at the question of blame, and at the possibility of a morally acceptable form of child-pornography. My approach involves an objectivist meta-ethics and a utilitarian view of practical ethics, and I bring out the advantages of these theories to the consideration of moral issues such as this one.

Social Anxiety Disorder (SAD) is a heterogeneous and distressing problem for many children and youth. This review focuses on the etiology and maintenance of SAD, and examines research findings in several key areas of investigation: genetic or hereditary factors (twin and family studies), temperament characteristics (behavioural inhibition), and parent–child interactions (attachment, parenting styles). It is concluded that genetic influences, behavioural inhibition, and parent–child interactions play significant and interactive roles in the development and maintenance of SAD. Other influences such as peer relationships, social skills deficits, and traumatic experiences are also acknowledged. Ultimately, an understanding of such pathways should facilitate effective early screening and intervention of children at risk for severe social anxiety.  相似文献

Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn't have been instantiated. These views motivate Stalnaker's "two dimensional" account of the necessary a posteriori on which there is no single proposition that is both necessary and a posteriori. For a (metaphysically) necessary proposition is true in all (metaphysically) possible worlds. If there were necessary a posteriori propositions, that would mean that there were propositions true in all possible worlds but which could only be known to be true by acquiring empirical evidence. Consider such a purported proposition P. The role of empirical evidence for establishing P's truth would have to be to rule out worlds in which P is false. If there were no such worlds to be ruled out, we would not require evidence for P. But by hypothesis, P is necessary and so true in all metaphysically possible worlds. And on Stalnaker's view, the metaphysically possible worlds are all the worlds there are. So there can be no proposition that is true in all possible worlds, but that we require evidence to know. In this way, the motivation for Stalnaker's two dimensional account of the necessary a posteriori rests on his denying that there are metaphysically impossible Worlds. I argue that given his view of what possible worlds are, Stalnaker has no principled reason for denying that there are metaphysically impossible worlds. If I am right, this undercuts Stalnaker's motivation for his two dimensional account of the necessary a posteriori.

Previous researchers (e.g., J. A. Bargh, 1992, 2002) demonstrated the importance of nonconscious processes on consumer choice behavior. Using an advertisement, the authors determined the effect of two nonconscious processes--the mere exposure effect, which increases object preference by increasing consumer exposure to an object, and the endowment effect, which increases object valuation by providing consumer possession of an object--on consumer behavior. Although the mere exposure effect and endowment effect did not produce an interaction, they produced independent effects. The endowment effect increased object valuation but not object preference. The mere exposure effect increased object preference but not object valuation. Thus, at the unconscious level, an increase in object preference does not lead to an increase in object valuation, nor does an increase in object valuation lead to an increase in object preference. The authors discuss the importance of developing measures of unconscious process in advertising effectiveness.  相似文献

The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed.  相似文献

Young people aged 17–24 years are at high risk of being killed in road crashes around the world. Road safety interventions consider some influences upon young driver behaviour; for example, imposing passenger restrictions on young novice drivers indirectly minimises the potential negative social influences of peers as passengers. To change young driver risky behaviour, the multitude of psychosocial influences upon its initiation and maintenance must be identified. A study questionnaire was developed to investigate the relationships between risky driving and Akers’ social learning theory, social identity theory, and thrill seeking variables. The questionnaire was completed by 165 participants (105 women, 60 men) residing in south-east Queensland, Australia. The sociodemographic variables of age, gender, and exposure explained 19% of the variance in self-reported risky driving behaviour, whilst Akers’ social learning variables explained an additional 42%. Thrill seeking and social identity variables did not explain any significant additional variance. Significant predictors of risky driving included imitation of the driving behaviours of, and anticipated rewards and punishments administered by, parents and peers. Road safety policy that directly considers and incorporates these factors in their design, implementation, and enforcement of young driver road safety interventions should prove more efficacious than current approaches.  相似文献

I propose that an ill‐appreciated contrast between the examples Socrates gives Meno, to show him how he ought to philosophize, is the key to understanding the Meno. I contend that Socrates prefers his definitions of shape to his account of color because the former are concerned with what shape is, while the latter is concerned with how color comes to be. This contrast suggests that Plato intends an analogous contrast between the (properly philosophical) way of inquiry that leads to Socrates' definition of knowledge as “true belief tied down with an account” and the (not properly philosophical) way of inquiry that leads to Socrates' account of how knowledge comes to be, that is, the “theory of recollection.”  相似文献

The consequences of aggression on problem course and suicide risk were examined in 270 acutely suicidal adolescents (ages 12-17 years; 184 girls). Participants were assessed during psychiatric hospitalization (T1), 6-months post-hospitalization (T2), and 15 or more months post-hospitalization (T3). Study variables included self- and parent-reported aggression; self-reported internalizing symptoms, suicidal ideation, suicide attempt, and adverse events; and clinician-rated suicidal behavior. Aggression was not directly related to suicide attempt concurrently or prospectively. However, among more aggressive youth, internalizing symptoms were more predictive of T3 suicide attempt than among less aggressive youth. T1 aggression predicted aggressive incidents and the likelihood of incarceration prior to T3. Two-level hierarchical linear modeling indicated that self-reported aggression and internalizing problems were linked in terms of severity and rates of decline over time. Overall, parent-reported aggression was negatively associated with suicidal ideation. Findings highlight (a) the continuity and consequences of aggression, (b) a possible role of aggression in worsening suicide risk factors and potentiating suicide attempt, and (c) the importance of ongoing research on subtypes of suicidal adolescents.  相似文献
