So far in this course we have dealt entirely with the evolution of characters that are controlled by simple Mendelian inheritance at a single locus. There are notes on the course website about gametic disequilibrium and how allele frequencies change at two loci simultaneously, but we didn’t discuss them. In every example we’ve considered we’ve imagined that we could understand something about evolution by examining the evolution of a single gene. That’s the domain of classical population genetics. For the next few weeks we’re going to be exploring a field that’s actually older than classical population genetics, although the approach we’ll be taking to it involves the use of population genetic machinery. If you know a little about the history of evolutionary biology, you may know that after the rediscovery of Mendel’s work in 1900 there was a heated debate between the “biometricians” (e.g., Galton and Pearson) and the “Mendelians” (e.g., de Vries, Correns, Bateson, and Morgan). Biometricians asserted that the really important variation in evolution didn’t follow Mendelian rules. Height, weight, skin color, and similar traits seemed to

The present historical moment may seem a particularly inopportune time to review Bowling Alone, Robert Putnam's latest exploration of civic decline in America. After all, the outpouring of volunteerism, solidarity, patriotism, and self-sacrifice displayed by Americans in the wake of the September 11 terrorist attacks appears to fly in the face of Putnam's central argument: that \"social capital\" -defined as \"social networks and the norms of reciprocity and trustworthiness that arise from them\" (p. 19)'has declined to dangerously low levels in America over the last three decades. However, Putnam is not fazed in the least by the recent effusion of solidarity. Quite the contrary, he sees in it the potential to \"reverse what has been a 30to 40-year steady decline in most measures of connectedness or community.\"' As an example of how the current \"war on terrorism\" could generate a durable civic renewal, Putnam points to the burst in civic practices that occurred during and after World War II, which he says \"permanently marked\" the generation that lived through it and had a \"terrific effect on American public life over the last half-century.\" 3 If Americans can follow this example and channel their current civic

Bowling alone: The collapse and revival of American community

We investigate conditions sufficient for identification of average treatment effects using instrumental variables. First we show that the existence of valid instruments is not sufficient to identify any meaningful average treatment effect. We then establish that the combination of an instrument and a condition on the relation between the instrument and the participation status is sufficient for identification of a local average treatment effect for those who can be induced to change their participation status by changing the value of the instrument. Finally we derive the probability limit of the standard IV estimator under these conditions. It is seen to be a weighted average of local average treatment effects.

Evolution and Rationality Some Recent Game-Theoretic Results. Identification and Estimation of Local Average Treatment Effects

With digital equipment becoming increasingly networked, either on wired or wireless networks, for personal and professional use alike, distributed software systems have become a crucial element in information and communications technologies. The study of these systems forms the core of the ARLES' work, which is specifically concerned with defining new system software architectures, based on the use of emerging networking technologies. In this context, we concentrate on the study of distributed systems which bring to life the vision of ubiquitous computing systems, also known as ambient intelligence.

Statistical Methods For Agricultural Workers

Acute liver failure (ALF) is a life-threatening condition characterized by jaundice, encephalopathy and coagulopathy leading to multiorgan failure in a patient with no prior history of liver disease. Forty three consecutive patients of ALF admitted in Pediatric ICU were studied for etiology and prognostic factors. Etiology was established in 91% cases. Viral infections were the most common cause. Mortality rate was 44%. Increasing grade of encephalopathy, >7 days interval between the onset of prodromal symptoms and encephalopathy, blood glucose 10mg/dL and pH 7.45 on admission were found to be associated with increased risk of mortality.

Etiology and prognostic factors of acute liver failure in children

The impacts of information on returns from farming: evidence from a nationally representative farm survey in India

This paper investigates the process of convergence and catching-up among major Indian states during 1980/81–2004/05—a period of economic liberalisation and accelerated economic growth, and also analyses the factors that enhance economic growth and lead states towards an identical steady state. In particular, we examine the role of agricultural conditions in this process. Results indicate absolute divergence in income levels across states. However, after controlling for structural characteristics of states there is a strong tendency of convergence among states. Physical infrastructure and human capital are found to enhance economic growth, but alone are not sufficient for convergence. For convergence, the investment in physical infrastructure and human resources should be accompanied by a reduction in employment pressure on agriculture by improving labour market linkages of agriculture with non-agricultural sectors, and by promoting growth-enhancing labour-intensive agricultural technologies.

Agriculture, economic growth and regional disparities in India

Using district-level panel data, this paper has assessed sensitivity of Indian agriculture to climate change. Results show that a rise in temperature would reduce agricultural productivity, while rainfall unless it is in excess, will tend to counterbalance harmful effects of temperature. Irrigation is an important adaptation strategy to reduce harmful effects of warmer climate. Predictions suggest that by end of this century, a significant change in climate may reduce productivity of Indian agriculture by 25 per cent. Agriculture in arid and semi-arid regions is more sensitive to climate change, and would be more impacted by climate change. The loss will be higher in the absence of adaptation.
