This article discusses the effect of available contraceptive methods upon women's lives. It quotes extensively from letters received from women who answered a press appeal for information. The main argument is that contraception is by no means the trouble free panacea it is often assumed to be. For many women, contraception can bring considerable mental and physical side- effects—pain, anxiety, discomfort. Women also have to deal with the patriarchal attitudes of the medical profession and—often unsympathetic—partners. The women's accounts show how experience of contraception can be a radicalising experience—feeding the beginnings of a feminist awareness.The article was written before the latest evidence of a connection between the pill and breast cancer was made known.  相似文献

Previous research about firms’ perceptions on the usefulness of public research has not distinguished between technological innovators and non-innovators. With the exception of openness of search, we find that factors shaping such perceptions differ in both types of firms. Non-innovators need market power and the presence of an R&D department to profit from public knowledge. Innovators need less sheltered environments and lesser R&D effort, though the availability of resources and absorptive capacity is necessary. Using a sample of 1,031 Spanish manufacturing firms, we conclude that practical experience in technological innovation enhances firms’ perceptions on the usefulness of public research, not directly but by enabling certain internal changes, i.e. it produces encounters between corporate choices and public research.  相似文献

The effect of substrate interferences from high‐density polyethylene (HDPE) on the ability to associate an ignitable liquid residue with the corresponding liquid standard, using statistical procedures, is demonstrated. Gasoline, kerosene, and lighter fluid, at three different evaporation levels, were spiked onto HDPE and subsequently burned to generate simulated ignitable liquid residues (ILRs). Samples were extracted using a passive headspace procedure and analyzed by gas chromatography–mass spectrometry. The total ion chromatograms were subjected to data pretreatment procedures prior to principal components analysis and Pearson product moment correlation. Using the combination of these statistical procedures, simulated ILRs were successfully associated with the corresponding liquid type, despite the presence of compounds inherent to the HDPE substrate, as well as those resulting from pyrolysis of the substrate.  相似文献

Abstract

The identification of offence-related cognition is a major target of most cognitive–behavioural treatment programmes for sexual offenders, and a number of measures are available for this purpose. This study assessed the psychometric properties of a brief measure of beliefs that support and justify child sexual abuse: the Sex With Children (SWCH) scale. Factor analysis revealed two distinct types of belief: that sex with children is harmless, and that children actively provoke adults into having sex with them. The SWCH was also found to have good internal consistency, test–retest reliability and concurrent validity. Child molesters scored significantly more highly on the SWCH than did rapists or non-offenders, and high-risk child molesters reported more entrenched offence-supportive beliefs than lower risk child molesters. A relationship was also observed between general offence-supportive beliefs as measured by SWCH and offence-specific cognitions ascribing responsibility or enjoyment to the offender's victim. The SWCH subscales appeared to closely match two of the implicit theories hypothesized by Ward and Keenan (1999 Ward, T. and Keenan, T. 1999. Child molesters’ implicit theories. Journal of Interpersonal Violence, 14: 821838. [Crossref], [Web of Science ®] [Google Scholar]) to be related to child molestation. Sex offender treatment providers need to be aware of the relationship between underlying implicit theories and offence-specific distorted cognitions about the victim's experience.  相似文献

In Dun & Bradstreet v. Greenmoss Builders, the Supreme Court of the United States reintroduced a subject matter test into libel law, holding that private figures defamed in the discussion of matters of private concern did not need to prove actual malice to collect punitive or presumed damages. The sweeping language of some of opinions, coupled with the Supreme Court's references to subject matter in subsequent cases, led to confusion over whether and how constitutional protections apply in private plaintiff-private issue cases. This article explores how lower federal and state appellate courts have interpreted Dun & Bradstreet and offers three alternate solutions to appropriately balance the First Amendment rights of defendants with the reputational interests of private plaintiffs in cases arising from the discussion of matters of private concern.  相似文献
