In this paper Malmquist productivity index(MPI) for decision making unit(DMU) with interval data has been evaluated.A method for assessing Malmquist productivity index using cost efficiency also has been developed.The applicability of the methods developed is illustrated in the context of the analysis of groups of teaching of university performance.

Whether it be a rugby team or a rescue crew, ensuring peak group performance is a primary goal during collective activities. In reality, however, groups often suffer from productivity losses that can lead to less than optimal outputs. Where researchers have focused on this problem, inefficiencies in the way team members coordinate their efforts has been identified as one potent source of produc...

Both theory and evidence suggest that diversity stabilises productivity in herbaceous plant communities through a combination of overyielding, species asynchrony and favourable species interactions. However, whether these same processes also promote stability in forest ecosystems has never been tested. Using tree ring data from permanent forest plots across Europe, we show that aboveground wood...

Although precipitation interannual variability is projected to increase due to climate change, effects of changes in precipitation variance have received considerable less attention than effects of changes in the mean state of climate. Interannual precipitation variability effects on functional diversity and its consequences for ecosystem functioning are assessed here using a 6-year rainfall ma...

The historical context surrounding the birth of the DARPA High Productivity Computing Systems (HPCS) program is important for understanding why federal government agencies launched this new, longterm high performance computing program and renewed their commitment to leadership computing in support of national security, large science, and space requirements at the start of the 21st century. In t...

The TPC/27 detector and the PEP machine have been upgraded for highluminosity running. We describe the performance of the new configuration during a test run in fall 1988. Prospects for progress in 7 physics, based on a large data sample to be recorded by the TPC/Zy detector, are reviewed.

Recent research has demonstrated the existence of a positive relationship between IT investment and productivity in the context of large firms. However, the validity of such relationship for small and medium enterprises (SMEs) has not yet been established. The issue is of critical importance for SMEs, which suffer a constant struggle for survival due to the absence of slack resources and high c...

Triple product correlations (TPC’s) involving strange quark spin are elucidated in b → uūs process within the standard model. They arise when light quark masses are nonzero. As the momenta and spins of constituent quarks are related to that of the parent hadron, the quark masses are, however small, important and relevant in TPC studies. At this level the TPC’s of interest are of the form ~ss · ...

Numerous studies show that increasing species richness leads to higher ecosystem productivity. This effect is often attributed to more efficient portioning of multiple resources in communities with higher numbers of competing species, indicating the role of resource supply and stoichiometry for biodiversity-ecosystem functioning relationships. Here, we merged theory on ecological stoichiometry ...

ABSTRACT An expected outcome of economic reforms in India is enhanced pace of industrialization with manufacturing sector playing a crucial role by increasing its share in output via higher investments and increased productivity. This process of industrialization was also expected to usher in possibilities for the slow growing states to catch up with the fast growing ones. This paper assesses t...
