This paper analyses the changing competence requirements which members of the food chain face in their pursuit of competitive advantage. Two groups of trends serve as point of departure: more dynamic and heterogeneous consumer demands, which can be analysed in terms of consumer demands for sensory, health, process and convenience qualities, and changing roles for retailers in the food chain. Ba...

A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic balance of BDE and triols.

overdue. Relying on highly selective published extracts from Haeckel's archive is unsatisfactory because of the biases of various editors. Use of Haeckel's extensive correspondence and other materials, such as newspaper clippings, would have given Sandmann the opportunity of locating Haeckel in the changing socio-political context of Imperial Germany, as bourgeois opinion shifted from liberalis...

We investigate colors and mass-to-light ratios (M/Ls) of the bulges and disks for 28 nearby spiral galaxies with various morphological types of Sab to Scd, using images in optical and near-infrared (V , I, and J) bands and published rotation curves. It is shown that the observed colors and M/Ls generally agree with the galaxy formation model with an exponentially declining star formation rate a...

This paper demonstrates ETLMR, a novel dimensional Extract– Transform–Load (ETL) programming framework that uses MapReduce to achieve scalability. ETLMR has built-in native support of data warehouse (DW) specific constructs such as star schemas, snowflake schemas, and slowly changing dimensions (SCDs). This makes it possible to build MapReduce-based dimensional ETL flows very easily. The ETL pr...

Abstract In recent decades, because of the vast socio-cultural changes which occurred in Iran, Iranian women have experienced new values and identities and they have achieved more advanced education and consciousness, so that they oppose the gender stereotypes which attribute inferior characteristics to women and cause inequalities and limitations in their everyday life. Although gender stereo...
