The purpose of this study was to gain a clearer understanding of the relation between parents’ knowledge of their emerging-adult
children and emerging adults’ risk behaviors. Participants included 200 undergraduate students between the ages of 18 and
25 (121 women, 78 men; M
age = 19.59, SD = 1.62) and both of their parents. Results revealed that knowledge of the emerging-adult child’s activities varied as a function
of parent- and child-reports, and that child outcomes associated with parental knowledge were generally positive, including
less drinking, drug use, and risky sexual behavior (although this varied as a function of reporter). The links between maternal
knowledge and lower drug and alcohol use were particularly strong in the presence of maternal closeness. Implications for
understanding the parent–child relationship during the transition to adulthood were discussed.

基准时间是宏观历史过程中的临界点,标志着一连串的重大变革可能会在较长时间内延续。基准时间具有九条标准,可以分为一等基准时间、二等基准时间和三等基准时间。20世纪的基准时间主要包括三次世界大战(一战、二战和冷战),第二次世界大战前后发生的变革比第一次世界大战和冷战前后的变革都要来得更为深远。将20世纪的三个基准时间置于两个世纪的视角中加以审视,可以突出现代性革命,这种视角能够观察20世纪的三个基准时间在正在展开的"全球性变革"这一大的主题下是否会相互联接、是如何相互联接的。20世纪国际政治的关键事件,都应该被视为19世纪"全球性变革"所引发的发展态势和挑战的后期结果。 相似文献

Since President Hugo Chávez was first elected in 1998, the Venezuelan opposition seems to have alternated between institutional and extra‐institutional power strategies at different junctures. To help explain this pattern, this article constructs a novel theoretical framework from critical readings of both general theory and accounts of the Venezuelan opposition. It proposes that the strategies should be viewed as dialectical rather than discrete. On this basis, it finds that while the Venezuelan opposition has undergone important changes toward institutionalization in its composition, discursive emphasis, and strategic direction, close readings of opposition texts, interviews with opposition actors, and observations of street demonstrations all reveal continuity with previous rupturist and extra‐institutional tendencies. Both strategies therefore must be considered to achieve a fuller, more comprehensive vision of the Venezuelan opposition; this conclusion has important theoretical implications for the study of opposition in the wider region. 相似文献

Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone. 相似文献

In 2017, significant media and political interest was sparked by the UK decision to leave Euratom, the European Atomic Energy Community. While such interest in nuclear matters has to be welcomed, the apparent lack of knowledge displayed in the regulatory governance of the UK nuclear industry is disquieting. This article therefore offers an overview of the publicly funded UK nuclear industry and its regulatory governance including its links with European and global nuclear agencies to inform the debate and to identify critical issues in need of resolution. 相似文献
