Social Preferences, Goal Orientation and Team Performance

Previous research on Goal Orientation (GO) and Social Value Orientation (SVO) examined and found relationships between performance and each construct. This study is built on GO and SVO literature and proposes that there is a relationship between the tendency to adopt learning or performance goals and social value orientations and that both constructs jointly influence team performance. Two sets of participants were asked to answer scales about GO, SVO, and Team Performance. Structural equation models tested the hypotheses

Membrane currents in cultured human intestinal smooth muscle cells.

Tropical peatlands store ~75 Pg carbon and have operated as long-term net carbon sinks throughout the Holocene. However, intensive land development is destabilizing these reservoirs, resulting in large carbon emissions to the atmosphere and loss of valuable low-latitude peat paleorecords

Precision studies of Fermi gases using Bragg spectroscopy

We have used Bragg spectroscopy to make precise measurements of a number of properties of a strongly interacting Fermi gas. These include the dynamic spin and density response functions, the static structure factors and Tan's universal contact parameter. We also present a technique for obtaining the homogeneous response functions and contact using measurements on a trapped (inhomogeneous) system

Homocysteine, folate, vitamin B12, and cardiovascular risk in Indians, Malays, and Chinese in Singapore

OBJECTIVE—To examine the hypothesis that the higher rates of coronary heart disease (CHD) in Indians (South Asians) compared with Malays and Chinese is partly attributable to differences in blood concentrations of homocysteine, and related blood concentrations of folate and vitamin B12.
DESIGN—Cross sectional study of the general population.
SETTING—Singapore.
PARTICIPANTS—Random sample of 726 fasting subjects aged 30 to 69( )years.
MAIN RESULTS—Mean plasma total homocysteine concentrations did not show significant ethnic differences; values were Indians (men 16.2 and women 11.5 µmol/l), Malays (men 15.0 and women 12.5 µmol/l), and Chinese (men 15.3 and women 12.2 µmol/l). Similarly, the proportions with high plasma homocysteine (>14.0 µmol/l) showed no important ethnic differences being, Indians (men 60.0 and women 21.9 %), Malays (men 53.9 and women 37.8 %), and Chinese (men 56.6 and women 30.6 %). Mean plasma folate concentrations were lower in Indians (men 8.7 and women 10.9 nmol/l) and Malays (men 8.5 and women 10.8 nmol/l), than Chinese (men 9.7 and women 13.8 nmol/l). Similarly, the proportions with low plasma folate (<6.8 nmol/l) were higher in Indians (men 44.9 and women 36.6 %) and Malays (men 45.3 and women 24.5 %) than Chinese (men 31.4 and women 12.6( )%). Mean plasma vitamin B12 concentrations were lowest in Indians (men 352.5 and women 350.7 pmol/l), then Chinese (men 371.1 and women 373.7 pmol/l), and then Malays (men 430.5 and women 486.0( )pmol/l).
CONCLUSION—While there were ethnic differences for plasma folate and vitamin B12 (in particular lower levels in Indians), there was no evidence that homocysteine plays any part in the differential ethnic risk from CHD in Singapore and in particular the increased susceptibility of Indians to the disease.
