The Influence of Implicit Math Anxiety on Math Achievement.

Previous work has noted that math anxiety may have a profound effect on math performance; however extant research has relied on measures that explicitly assess math anxiety. This study examined the effects of implicit math anxiety on the performance of a math achievement task. We hypothesized that combined measure of implicit anxiety and explicit anxiety would better predict math achievement than measures of explicit math anxiety alone.

Effects of Disease Threat and Attitude Similarity on Willingness to Help: The Mediating Role of Disgust.

The current research tested the hypothesis that an increase in perceived disease vulnerability would create more feelings of disgust and a reduced willingness to help persons with dissimilar attitudes. To test these hypotheses, two studies were performed. In the first study, 173 university undergraduates indicated their willingness to help a target person who held similar or dissimilar attitudes.

Effects of Self-Esteem Threat on Physical Attractiveness Stereotypes.

Certainly one of the first things that we notice when meeting someone new is how physically attractive that they are. Although the vast majority of studies in the literature suggest favoritism for physically attractive humans, some research indicates that negative biases may occur as well. This discrepancy in the literature may simply indicate the failure of differing experimental methods to adequately tap the same construct; however, it is also a likely indicator of moderating factors at work.

Herbal fertility treatments used in North America from colonial times to 1900, and their potential for improving the success rate of assisted reproductive technology.

This paper serves to fill a gap in the literature regarding evidence for the use of botanical remedies in the promotion of fertility. It examines the botanical remedies that were used in North America (1492-1900) for all stages of reproduction from preconception to birth, and discusses their potential for future use with present-day infertility treatments. Each medicinal plant discussed in this paper is assessed using an ethnomedicinal methodology that entails examining the published ethnobotanical, phytochemical and pharmacological data.

The Influence of Physical Attractiveness on Belief in a Just World.

Previous work has consistently found that belief in a just world is strongly correlated with societal privilege. In the present study, we examined the influence of physical attractiveness on belief in a just world. We hypothesized that physically attractive individuals would be stronger endorsers of belief in a just world, whereas less attractive individuals would be less likely to endorse belief in a just world.

Diversity and biogeographical patterns of legumes (Leguminosae) indigenous to southern Africa.

The principal aim of this study was to establish biogeographical patterns in the legume flora of southern Africa so as to facilitate the selection of species with agricultural potential. Plant collection data from the National Herbarium, South Africa, were analysed to establish the diversity and areas covered by legumes (Leguminosae/Fabaceae) indigenous to South Africa, Lesotho and Swaziland. A total of 27,322 records from 1,619 quarter degree grid cells, representing 1,580 species, 122 genera and 24 tribes were included in the analyses.

Effects of Instructor Attractiveness on Learning.

Although a considerable body of research has examined the impact of student attractiveness on instructors, little attention has been given to the influence of instructor attractiveness on students. This study tested the hypothesis that persons would perform significantly better on a learning task when they perceived their instructor to be high in physical attractiveness. To test the hypothesis, participants listened to an audio lecture while viewing a photograph of instructor.

Radiocarbon dating of American pika fecal pellets provides insights into population extirpations and climate refugia.

The American pika (Ochotona princeps) has become a species of concern for its sensitivity to warm temperatures and potential vulnerability to global warming. We explored the value of radiocarbon dating of fecal pellets to address questions of population persistence and timing of site extirpation. Carbon was extracted from pellets collected at 43 locations in the western Great Basin, USA, including three known occupied sites and 40 sites of uncertain status at range margins or where previous studies indicated the species is vulnerable.

Gene movement and genetic association with regional climate gradients in California valley oak (Quercus lobata Née) in the face of climate change.

Rapid climate change jeopardizes tree populations by shifting current climate zones. To avoid extinction, tree populations must tolerate, adapt, or migrate. Here we investigate geographic patterns of genetic variation in valley oak, Quercus lobata Née, to assess how underlying genetic structure of populations might influence this species' ability to survive climate change.

Reversed gender distribution of diabetes in Northern Canada.

Objectives: To determine age and gender distributions of prevalent diabetes and related risk factors for Northern Canadians.

Study Design: Cross-sectional study.

Methods: The data used were from 78,549 people aged 40 years or more (including 1148 from Northern Canada) who participated in a national survey in 2005.

Reprint of: survey of medicinal cannabis use among childbearing women: patterns of its use in pregnancy and retroactive self-assessment of its efficacy against 'morning sickness'.

A majority of women experience some nausea and/or vomiting during pregnancy. This condition can range from mild nausea to extreme nausea and vomiting, with 1-2% of women suffering from the life-threatening condition hyperemesis gravidarum. Cannabis (Cannabis sativa) may be used therapeutically to mitigate pregnancy-induced nausea and vomiting.

Conserving the evolutionary potential of California valley oak (Quercus lobata Née): a multivariate genetic approach to conservation planning.

California valley oak (Quercus lobata Née) is a seriously threatened endemic oak species in California and a keystone species for foothill oak ecosystems. Urban and agricultural development affects a significant fraction of the species' range and predicted climate change is likely to dislocate many current populations. Here, we explore spatial patterns of multivariate genotypes and genetic diversity throughout the range of valley oak to determine whether ongoing and future patterns of habitat loss could threaten the evolutionary potential of the species by eradicating populations of distinctive genetic composition.

Reentrant supraventricular tachycardia in a pediatric trauma patient masquerading as a cardiac contusion.

Establishing the etiology of tachycardia in a trauma patient is often difficult. Pediatric trauma patients present an even tougher challenge. Cardiac contusion should be suspected when other more common traumatic injuries that produce hypoxia and blood loss are excluded.

A two-generation analysis of pollen pool genetic structure in flowering dogwood, Cornus florida (Cornaceae), in the Missouri Ozarks.

Anthropogenic landscape change can disrupt gene flow. As part of the Missouri Ozark Forest Ecosystem Project, this study examined whether silvicultural practices influence pollen-mediated gene movement in the insect-pollinated species, Cornus florida L., by comparing pollen pool structure (Φ(st)) among clear-cutting, selective cutting, and uncut regimes with the expectation that pollen movement should be least in the uncut regime.

Herbal healing in pregnancy: women's experiences.

Many women use home remedies to maintain their health during pregnancy. Here, pregnant women's perspectives on herbal medicine are exposed in a small (n = 27) non-random sample of pregnant women in British Columbia, Canada, and follow-up interviews with six mentors from the community. While many of the women were cautious about using herbs during pregnancy, they considered them to be safer-as a general rule-than pharmaceutical drugs.

The rhetoric of "natural" in natural childbirth: childbearing women's perspectives on prolonged pregnancy and induction of labour.

It is widely known that the notion of prolonged pregnancy, defined medically as 41+ or 42+ weeks gestation, has been hotly debated within the medical and midwifery communities for many decades. Within this debate, pregnant women's voices have rarely been heard. Presented here are the results of a qualitative study of self-care in pregnancy, birth and lactation with a non-random sample of women in British Columbia, Canada.

Use of anti-emetic herbs in pregnancy: women's choices, and the question of safety and efficacy.

The majority of North American pregnant women experience some degree of nausea and vomiting, usually in the first few months of pregnancy. Women utilize many coping strategies, including self-treatment with herbal medicine and other alternative therapies. In a qualitative study of self-care in pregnancy, birth and lactation within a non-random sample of 27 women in British Columbia, Canada, 20 women (74%) experienced pregnancy-induced nausea.

Two-generation analysis of pollen flow across a landscape V: a stepwise approach for extracting factors contributing to pollen structure.

Patterns of pollen dispersal are central to both the ecology and evolution of plant populations. However, the mechanisms controlling either the dispersal process itself or our estimation of that process may be influenced by site-specific factors such as local forest structure and nonuniform adult genetic structure. Here, we present an extension of the AMOVA model applied to the recently developed TWOGENER analysis of pollen pool structure.

Herbal medicine in pregnancy and childbirth.

Pregnant women often use medicinal herbs in an effort to maintain good health and reduce the need for medical intervention. A survey of the scientific and popular literature identified a number of therapeutic herbs used in North America. Three categories are discussed: tonics, herbs for preventing miscarriage, and herbs for inducing labor.

Two-generation analysis of pollen flow across a landscape. I. Male gamete heterogeneity among females.

Gene flow is a key factor in the spatial genetic structure in spatially distributed species. Evolutionary biologists interested in microevolutionary processess and conservation biologists interested in the impact of landscape change require a method that measures the real time process of gene movement. We present a novel two-generation (parent-offspring) approach to the study of genetic structure (TwoGener) that allows us to quantify heterogeneity among the male gamete pools sampled by maternal trees scattered across the landscape and to estimate mean pollination distance and effective neighborhood size.

FINE-SCALE GENETIC STRUCTURE OF WHITEBARK PINE (PINUS ALBICAULIS): ASSOCIATIONS WITH WATERSHED AND GROWTH FORM.

The fine-scale genetic structure of a subalpine conifer, whitebark pine (Pinus albicaulis Engelm.), was studied at nested geographic levels from watershed to adjacent stems in the eastern Sierra Nevada Range of California. A combination of several characteristics contributed to unpredicted genetic structure in this species.
