Rotten Spouses, Family Transfers and Public Goods We show that once interfamily exchanges are considered, Becker’s rotten kids mechanism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva’s (1999) result of efficiency in the contribution game amongst siblings extends to a setting where the contributors (spouses) belong to differe...

agricultural sector experiences the application of automated systems since two decades ago. these systems are applied to harvest fruits in agriculture. computer vision is one of the technologies that are most widely used in food industries and agriculture. in this paper, an automated system based on computer vision for harvesting greenhouse tomatoes is presented. a ccd camera takes images from ...

Melon is considered a product of high commercial value, but its post-harvest shelf life short at room temperature. As an alternative to reducing postharvest losses, osmotic dehydration arouses interest as pre-treatment for fruit drying. The present work aimed obtain the drying curves in osmotically dehydrated melons, followed by conventional A syrup was prepared using crushed crystal sugar up c...

We explore the generality of Konrad and Lommerud (1995)’s Rotten Spouse Theorem. While the result holds for an arbitrary number of agents, it fails to hold for general technologies. We discuss some of the implications for CO2-emissions models.

Physiological studies of strongly photoperiodic species in lonig alnd short day have hitherto dealt predominiantly with the effect of day length upon development rather than uponl growth. In photoperiodic species which flower in only one of two contrasted day lengths, it becoiles difficult to compare or interpret data on growth due to simultaneous developmental differences of plants grown in un...

The effect of gaseous ozone and hot water, alone or in combination, on the sensory and microbial quality of cantaloupe melon was investigated. Escherichia coli O157:H7 transmission from the rind to edible melon flesh during cutting practices was also investigated. Four different treatments consisting of hot water (75 degrees C, 1min), gaseous ozone (10,000ppm, 30min), gaseous ozone supplied by ...

Salt- and drought-induced alterations in citrulline were assessed in 4 local melon genotypes, 2 sensitive (CU-52, CU-94) and 2 tolerant (CU-196, CU-280), grown in vermiculite in a growth chamber. Salt and drought stresses were started using 30-day-old plants, with 250 mM NaCl and 45 mM PEG (-1.0 MPa) and continued for 12 days. After 12 days under salt and drought conditions, the citrulline cont...
