In this paper I do two things: (1) I support the claim that there is still some confusion about just what the Quine-Putnam
indispensability argument is and the way it employs Quinean meta-ontology and (2) I try to dispel some of this confusion by presenting the argument in
a way which reveals its important meta-ontological features, and include these features explicitly as premises. As a means
to these ends, I compare Peter van Inwagen’s argument for the existence of properties with Putnam’s presentation of the indispensability
argument. Van Inwagen’s argument is a classic exercise in Quinean meta-ontology and yet he claims – despite his argument’s
conspicuous similarities to the Quine-Putnam argument – that his own has a substantially different form. I argue, however,
that there is no such difference between these two arguments even at a very high level of specificity; I show that there is
a detailed generic indispensability argument that captures the single form of both. The arguments are identical in every way
except for the kind of objects they argue for – an irrelevant difference for my purposes. Furthermore, Putnam’s and van Inwagen’s
presentations make an assumption that is often mistakenly taken to be an important feature of the Quine-Putnam argument. Yet
this assumption is only the implicit backdrop against which the argument is typically presented. This last point is brought
into sharper relief by the fact that van Inwagen’s list of the four nominalistic responses to his argument is too short. His
list is missing an important – and historically popular – fifth option.

This paper reports on a study of the relationship between demographic, personality, and attitudinal variables and impulsive buying (a consumer's tendency to buy spontaneously, unreflectively, and immediately); using secondary analysis of data from common participants in two large national surveys of British adults: one survey contributing data on impulsive buying, demographics, and money attitudes; and the second, a Big Five personality trait measure. In particular, we focus on the attitudes characterized by the extent to which individuals associate money with security, freedom, power, and love. Younger females and those with higher household income were more likely to engage in impulsive buying. Correlational and regression analysis showed that those high on Neuroticism and Extraversion and those low on Conscientiousness were more likely to be impulse buyers. All four money attitudes were related to impulsive buying (Money as Security most strongly). A hierarchical regression indicated that demographic variables accounted for 3 percent, personality a further 9 percent, and money attitudes a further 13 percent of the variance, showing that these three sets of variables accounted for around a quarter of the variance. Implications are considered for educational and therapeutic interventions in reducing maladaptive impulsive buying. 相似文献

This study is based on exploring the trust between peers and the individual characteristics related to homophobic bullying in adolescence. Participants were 334 adolescents (141 boys and 193 girls) aged from 15 to 20 years. Participants completed the homophobic bullying scale, to investigate bullying actions towards sexual minorities, the personal attributes questionnaire, for personal characteristics, and the inventory of parent and peer attachment, to the trust between peers. The results demonstrated how female participants manifested a higher level of interpersonal traits and trust among peers than boys. Results showed how a lack of trust between peers predicts homophobic bullying. Nevertheless, we found that the lack of interpersonal characteristics represents a variable that likely mediates the relationship between lack of trust in peers and homophobic bullying. Theoretical and practical implications are discussed. 相似文献

Sexual and gender identity development theories in psychology and sociology exert considerable influence over discourse on gender and sexuality, shaping key domains such as counseling, education, and social work, as well as public policy and advocacy. While a robust body of literature has developed in critique of such theories and models, they continue to be applied in the Global South without much thought for their relevance to various non-Western cultural contexts. The current study explores the fit of these identity development theories to the experiences of 15 non-heterosexual and transgender individuals in Sri Lanka, gathered through a qualitative study of the question in 2016. These participants articulated gender and sexual self-conceptions that were incongruent with major identity development theories in significant ways. A broad majority failed to endorse central or salient sexual identities, while demonstrating a fluidity in object choice, sex roles, and sex acts, thus rupturing the theoretical notion of stable and coherent identities. Transgender participants did not demonstrate identity synthesis or pride and complicated theoretical understandings of sexual intimacy. These findings highlight the necessity of considering individual differences and cultural contexts when studying gender and sexuality and the dangers of universalizing theories across cultural differences. 相似文献

This article deals with relationships and marriages of the Tlingit with immigrants from the Russian Empire as well as with representatives of other European and non-European peoples during the period when Alaska belonged to the Russian Empire. Matrimonial relations existed in two variants: legal, sanctified by the church, and in the form of permanent extramarital cohabitation or casual relationships. The latter variant absolutely predominated. With this, there was a sharply reflected gender imbalance, since men absolutely predominated among the immigrants, and therefore Tlingit women emerged in the role of marriage partners in the overwhelming majority of cases. A directly opposite pattern was observed in Tlingit contacts with the Athapaskans and to some extent with the Eyak. Matrimonial connections exerted influence on the workings of the Russian colonization, stimulated growth in mixed populations, and facilitated gradual acculturation of the Tlingit, along with contributing to the expansion of their ethnic territory. 相似文献

The objective of this study was to identify the perception of body image by Tunisian women and their spouses and to examine its impact on female sexuality. Our study involved 300 Tunisian women who had been married for at least 1 year and consulted in primary care medicine during the months of June and July 2016. Each participant completed a questionnaire covering four areas: women’s perception of their body, the perception of the spouses of the latter as it was reported by the participants, sexual activity, and the impact of body perception on sexual activity. The participants were satisfied with their bodies in 51% of cases. This satisfaction was associated with perceiving the body as physically attractive (p?=?0.007), young (p?=?0.047) and as a source of confidence (p?<?0.001). Compared to women dissatisfied with their bodies, those satisfied declared satisfaction of sexual desire (p?=?0.005), reaching orgasm (p?=?0.001), taking the initiative in sexual activity (p?=?0.003) and preparation for sex (p?=?0.006). Perceived satisfaction of the partner with the female body was related to a more positive sexuality in women, specifically to women’s sexual satisfaction (p?=?0.018), women taking sexual initiative (p?=?0.014) and preparation for sex (p?=?0.001). Our study indicates the important impact of a positive perception of the body image of Tunisian women by themselves and by their spouses on their sexuality. It would be interesting to consider these aspects in the management of female sexual disorders. 相似文献

The adverse social and physical conditions of homelessness pose significant developmental risks for children, which may be compounded or buffered by the quality of parenting behaviour they are exposed to. There is currently a limited understanding of how parents approach their care-giving role and responsibilities while adjusting to the experience of homelessness. Advancing knowledge in this area is essential for developing acceptable, appropriate and effective interventions to support highly marginalised and vulnerable homeless families. This review explored homeless parents’ perceptions of how homelessness affects their parenting behaviour and identified adaptive strategies that parents may use to mitigate the potentially negative impacts of homelessness on the quality of care-giving. A systematic search of four electronic databases (ASSIA, PsycINFO, Web of Science and MEDLINE) identified 13 published qualitative studies, all originating from the USA, which explored parenting behaviour in homeless contexts. The studies were critically appraised using the CASP qualitative assessment tool. Thematic synthesis identified the following determinants of parenting behaviour; negative self-concept in the parental role, parental mental health, material resources, challenges to autonomy and self-efficacy, daily hassles, physical environment and service context, stigma, child characteristics and lack of support. These were synthesised thematically using existing models of parenting determinants and positive parenting. Findings indicate substantive impacts of homelessness on parental mental health, parenting authority, material resources, parenting environments and social support. Parents developed a number of adaptive methods to negotiate the challenges of homeless parenting such as maintaining a positive mindset, cherishing the parental role and developing practical strategies. We conclude with recommendations that service providers should tailor parenting support to resource-constrained circumstances and that further research is required in order to better understand experiences of homeless parents in other international contexts. 相似文献
