In extensively modified landscapes, how the matrix is managed determines many conservation outcomes. Recent publications revise popular conceptions of a homogeneous and static matrix, yet we still lack an adequate conceptual model of the matrix. Here, we identify three core effects that influence patch-dependent species, through impacts associated with movement and dispersal, resource availabil...

This paper examines the 'concrete analogies' underpinning the ontological commitments of dominant conceptions of ethics, politics and economics to show that the content of economics is implicated in conceptions of ethics, and that these conceptions cannot be separated from questions of research and professional ethics.

With the introduction of intracytoplasmic sperm injection (ICSI), couples with severe male factor infertility have been able to achieve fertilization and clinical pregnancy rates comparable to other in vitro fertilization patients. However, despite the utilization of microsurgical sperm injection techniques, failure of fertilization still occurs in a few patients. How such fertilization failure...

Neural tube defects (NTDs) are congenital malformations of the brain and spinal cord caused by the failure of neural tubes to close between 21 and 28 days after conception (Sadler, 2005). Any disruption of neurulation during or prior to this time may result in a defect or failure of neural tube closure. Non-invasive prenatal diagnostic testing by ultrasound and maternal serum screening, which s...

When David Lewis [19] introduced common knowledge, he used it as a key ingredient in his account of language as a convention. We ask how essential higher orders of knowledge of language are for communication success. We find that in common-interest communication games higher-order failure of knowledge of language, while potentially resulting in suboptimal language use at any finite knowledge or...

Background Persons living with HIV often face discrimination in safe sex and reproductive choices, especially in lowresource settings. This study assessed fertility desires and intentions, risk perception and correlates of ever use of at least one safer conception method among HIV-infected women attending a tertiary health facility ...

BACKGROUND Chronic renal failure is strongly associated with poor pregnancy outcome. Women dependent on hemodialysis before conception rarely achieve a successful live birth. CASE PRESENTATION A 31-year-old multiparous Turkish woman was scheduled for cesarean section under spinal anesthesia at 37 weeks and five days' gestation because of hemorrhage due to secondary placenta previa. Spinal ane...

Achromobacter xylosoxidans, a Pseudomonaslike bacterium, contaminated a boar stud laboratory’s water distillation and delivery system that was used for extension of raw semen for artificial insemination. In sow herds that used the contaminated semen, conception rates decreased and vulvar discharges, culled sows, and nonproductive sow days increased. Thorough diagnostic testing revealed that A x...
