The effects of lactose, galactose, glucose, and glucose combined with galactose on the induction of β–galactosidase by IPTG in Escherichia coli strain VC10, growing in a glycerol media, were compared against a control of glycerol plus IPTG. After inducing β– galactosidase production with the IPTG, the cultures were altered with the addition of one of the above carbohydrates or combinations. Thi...

As work organizations become increasingly gender diverse, existing theoretical models have failed to explain why such diversity can have a negative impact on idea generation. Using evidence from two group experiments, this paper tests theory on the effects of imposing a political correctness (PC) norm, one that sets clear expectations for how men and women should interact, on reducing interacti...

This paper studies the political economy of fertility. Specifically, I argue that fertility may be a strategic choice for ethnic groups engaged in redistributive conflict. I first present a simple conflict model where high fertility is optimal for each ethnic group if and only if the economy’s ethnic diversity is high and/or institutions are weak. I then test the model in a cross-national datas...

Decision making often entails conflict. In many situations, the symptoms of such decisional conflict are conspicuous. This article explores an important and unexamined question: How does observing someone else experiencing decisional conflict impact our own preferences? The authors show that observing others’ emotional conflict and agony over an impending decision makes the observer’s preferenc...

The subject matter of this paper is an investigation of factors affecting the women s' presence in politics (aged 20-40 years) in 2015 (Case study: City of Sanandaj). Political participation is regarded as one of the major development indices. If the political development is considered as meaning "expansion of participation and competition of social groups in the political life", one of its pre...

T mitotic spindle is an impressive cellular machine, responsible for distributing each set of the duplicated genome into daughter cells. Microtubules, the major component of the spindle, are constantly recycled by two turnover mechanisms: dynamic instability of microtubule plus ends and treadmilling, or flux of tubulin dimers toward the pole. Thus, the critical function of chromosome segregatio...

This paper explores how governments may efficiently inform the public about an epidemic to induce compliance with their confinement measures. Using information design framework, we find government has incentive either downplay or exaggerate severity of if it heavily prioritizes economy over population health vice versa. Importantly, that level economic inequality in effect on these distortions....

BACKGROUND Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. METHODS Data were derived from the 2008 General Social Survey-National Death Inde...
