Background: Partogram is being used since 1954 when Friedman described it for monitoring progress of labour. The Paperless Partogram proposed by Dr. Debdas is a low-skill method for detection of abnormal labour. The main aim of the study is to know efficacy and user friendliness   of paperless partogram in comparison with WHO partogram in monitoring and management of labour.Methods: It’s a prospective observational study conducted at Vanivilas hospital where 200 women in labour were included. 6 resident doctors in shifts were asked to fill partograms 100 each for paperless (group A) and WHO (group B).Results: Paperless partogram has scored better than WHO partogram in terms of documentation, learning, time for data entry, cost effectiveness and monitoring of labour.Conclusions: In our study paperless partogram was found to be preferred for monitoring of labour.

This paper develops a case study of the Internet adult industry in order to study the ways in which electronic commerce interacts with geography. Digital products, low barriers to entry, cost differentials, and sensitivity to regulation have created a pervasive and complex geography of models, webmasters, and consumers around the globe. With a series of specially developed datasets on the location of content production, websites, and hosting it is shown that the online adult industry offers people and places outside major metropolitan areas opportunities to become active purveyors of this type of electronic commerce. The roles of these actors, however, are not simply determined by a spaceless logic of cyber-interaction but by histories and economies of the physical places they inhabit. In short, the ‘space of flows’ cannot be understood without reference to the ‘space of places’ to which it connects. This geography also provides a valuable counterpoint to mainstream electronic commerce and highlights the ability of socially marginal and underground interests to use the Internet to form and connect in global networks.

This paper analyzes a labor market, where: workers can acquire an observable skill at no cost, firms differ in unobserved productivity, workers' skill and firms' productivity are substitutes, and firms' search is directed. The main result is that, if the entry cost of firms is small, no worker acquires the skill in the unique equilibrium. For intermediate entry costs, a positive measure of workers obtain the skill, and the number of skilled workers goes to one as entry costs become large. Welfare is highest when the entry cost is high. (JEL D21, D24, D82, D83, J24)

We study the long-run evolution of brand preferences, using new data on consumers' life histories and purchases of consumer packaged goods. Variation in where consumers have lived in the past allows us to isolate the causal effect of past experiences on current purchases, holding constant contemporaneous supply-side factors. We show that brand preferences form endogenously, are highly persistent, and explain 40 percent of geographic variation in market shares. Counterfactuals suggest that brand preferences create large entry barriers and durable advantages for incumbent firms and can explain the persistence of early-mover advantage over long periods.
