Analysis of the factors affecting the productivity of enterprise software projects the data of which had many missing values revealed five important findings. (1) Productivity was proportional to the root of the fifth power of test case density and the root of the fifth power of fault density. (2) Developing software with a high level of security or reliability are the main causes of low produc...

background and objective: lactic acid is widely used in the food, chemical and pharmaceutical industries. the major problems associated with lactic acid production are substrate and end-product inhibition, and by-product formation. membrane technology represents one of the most effective processes for lactic acid production. the aim of this work is to increase cell density and lactic acid produ...

Deep waters (c. 4200m) around the Crozet Islands have localised and isolated seabed communities on sediments lying beneath highly productive waters to the north and east of the Islands. The restricted areas of primary productivity are stimulated by natural iron fertilization from the volcanic islands, in an otherwise low productivity HNLC (High Nutrient Low Chlorophyll) region, characteristic o...

The paper investigates the effects of international trade in goods and capital movement on the productivity distribution and industry-wide productivity when countries are heterogeneous in the quality of their financial institutions. In autarky, firm heterogeneity in their productivities arises in countries with poor financial institutions, while all firms adopt a high-productivity technology in...

The problem of assessing the impact of firm entry and exit on aggregate productivity growth is addressed. The proposed method overcomes some problems with currently proposed methods. The paper also addresses some of the problems involved in aggregating outputs and inputs when firms enter and exit so that the one output and one input aggregate productivity decompositions can be applied. It turns...

PH (Puissance de Hydrogen) is an essential ingredient of soil that effects on fertility and productivity of dirt. Barddhaman district is a part of Lower Gangetic Plain fully covered by alluvial soil and popularly known as 'rice bowl of West Bengal' owing to its lofty production. This data article provides a block level data on soil PH that is essential for further investigation of the relations...

Morphological productivity is one of the key issues in the study of derivational morphology. This paper makes a survey of the quantitative measurements of morphological productivity so far proposed by different scholars, and tentatively attempts to point out the pros and cons and also feasibility of each measurement, with a view to provide some assistance for the future researcher who is going ...

This paper investigates the role of productivity on a firm’s organizational choice. We set up an industry-equilibrium model in which heterogeneous firms concurrently choose their type of inputs, ownership structure and location of production. In choosing their type of inputs, firms trade off the extra customization costs of adopting generic inputs against the reduced hold-up friction that gener...
