In a sample of 207 eighth grade students, we examined similarities between students and their friends in achievement motivation
and whether friendship support moderated these associations. Academic self-competence and intrinsic value for math and English
were assessed using both perceptions of friends and actual friend reports collected through friend nominations. For both sources
of information, there was a stronger positive association between students’ and friends’ academic self-competence when friendships
were rated as more supportive. Analyses predicting intrinsic value for math and English provided weaker evidence of an interaction.
Comparisons of the students’ perceptions and their friends’ actual reports suggested that students overestimated the degree
to which their friends had attitudes similar to their own. Students also perceived that their friends valued academics significantly
less than the friends actually reported. Results suggest that both friend and friendship characteristics are important for
understanding student achievement motivation.

Little is known about the impact of the relational context of adolescent sexual activity on depressive symptoms. The present
study examined trajectories of depressive symptoms among 6,602 adolescents (44% male, 60% White) taken from a nationally representative
study (Add Health). Sexually active youth in romantic and casual relationships were first compared to virgins and then to
each other by relational context. Longitudinal, multilevel models examined differences in the course of depressive symptoms
based on sexual activity separately by gender and age group (ages 12–14 and 15–18). Results indicated that when compared to
virgins, any differences in depressive symptoms by relational context of sex were present prior to youth’s sexual debut. The
few significant differences found between youth who had sex in romantic relationships verses those who had casual sex were
present before sexual initiation and not maintained over time, suggesting that casual sex in adolescence is not associated
with long-term risks for depressive symptoms.

Nonprofit entrepreneurship is largely viewed through the lens of commercialization, overshadowing other ways that entrepreneurship manifests within the sector. One such way involves nonprofits' tendency to meet workforce needs by substituting flexible for wage labor, which may be especially attractive to arts organizations given the proclivity of workers in this sector to be self-employed. The authors examine the use of flexible versus wage labor by nonprofit arts organizations, relying on panel data to account for changes in organizational size over time. The results provide evidence of a substitution effect, in which the use of wage labor by arts organizations declines in response to greater reliance on flexible labor. The findings suggest that nonprofit arts organizations are innovative employers, responding to changes in their resource environments by adjusting their mix of wage and flexible labor while also providing outlets for freelance arts workers to pursue their chosen line of work. 相似文献

The conventional approach to causation in negligence is the "but for" test, decided on the balance of probabilities. Even when supplemented by the "material contribution" principle, satisfying the onus of proof of causation can be an insuperable obstacle for plaintiffs, particularly in medical cases. Yet, having found a breach of duty, a court's sympathies may gravitate toward the plaintiff at this point in the case. Accordingly, courts have sometimes accepted a relaxation of strict causation principles. The judicial devices are described: a special principle of causation in particular duties of care; a shifting burden of proof; "bridging the evidentiary gap" by drawing a robust inference of causation; treating a material increase in risk as sufficient proof of causation; and permitting causation to be established on the basis of the loss of a material chance of achieving a better outcome and discounting damages. In Accident Compensation Corp v Ambros [2007] NZCA 304 the New Zealand Court of Appeal recognised the need for a legal device to ameliorate the injustice sometimes caused by the strict rules of causation, and preferred the "inferential reasoning" approach favoured by the Canadian common law for use in the context of the accident compensation scheme. It is hoped that the New Zealand Supreme Court approves Ambros if the opportunity arises. 相似文献

In this paper the by-products arising during the synthesis of 4-methylthioamphetamine (4-MTA) by LiAlH(4) reduction of 1-(4-methylthiophenyl)-2-nitropropene (nitropropene route) and reductive amination of 4-methylthiophenyl-2-propanone in the presence of NaCNBH(4) are investigated. The identification of 4-methylthio derivatives of N-(β-phenylisopropyl)benzaldimine, 4-methylthio derivative of N-(β-phenylisopropyl)benzyl methyl ketimine, 1-(4-methylthiophenyl)-N-(4-methylthiobenzyl)-2-propanamine, (RS) and (SS/RR)-N,N-di-[β-(4-methylthiophenyl)isopropyl]amine, 4-methylthiobenzyl ether and methylthiobenzoic acid methyl ester as most prominent impurities in crude 4-MTA synthesised by reductive amination of 4-methylthiophenyl-2-propanone, is reported. Methylthio derivatives of 2-methyl-3-phenylaziridine, 2-benzylaziridine, and 4-methylthio derivative of BMK oxime as route-specific markers of nitropropene route leading to 4-MTA, were also characterized. The identity of these compounds was confirmed by their independent synthesis. 相似文献

Data from 191 post-mortem cases where post-mortem blood beta-hydroxybutyrate (βHB) and acetone concentrations and vitreous humor glucose concentrations (where available) had been measured were retrospectively investigated to determine the markers required to identify and distinguish between Alcoholic Ketoacidosis (AKA), Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS). Blood βHB concentrations above 250 μg/mL were considered significant and it was shown to be the preferred marker of ketoacidosis. All cases with significant βHB detected also had acetone present (greater than 2mg/dL) demonstrating that acetone can be used as a marker to identify ketoacidosis and can be used to indicate when βHB measurement is necessary. Vitreous humor glucose concentrations above 6.9 mmol/L were considered high and indicative of hyperglycemia prior to death. Vitreous humor glucose concentrations can be used to distinguish between DKA and ketoacidosis from other causes and to identify deaths due to HHS. The data showed that ketoacidosis can occur without a history of alcoholism or diabetes. Many diabetics are undiagnosed for many years. Therefore, DKA or HHS should be considered in sudden or unexplained deaths and glucose should be routinely measured especially in cases with risk factors for diabetes including obesity, old age, a history of mental health problems or treatment with atypical antipsychotic drugs including clozapine, olanzapine, quetiapine and risperidone. 相似文献

This paper examines the labor market effects of state health insurance mandates that increase the cost of employing a demographically identifiable group. State mandates requiring that health insurance plans cover infertility treatment raise the relative cost of insuring older women of child-bearing age. Empirically, wages in this group are unaffected, but their total labor input decreases. Workers do not value infertility mandates at cost, and so will not take wage cuts in exchange, leading employers to decrease their demand for this affected and identifiable group. Differences in the empirical effects of mandates found in the literature are explained by a model including variations in the elasticity of demand, moral hazard, ability to identify a group, and adverse selection. 相似文献
