"The purpose of this study is A) to identify the criteria for establishing permanent off-campus facility for existing centers. B) To identify the number of students from College of the Desert (COD) who are planning to continue their education at the California State University, Coachella Valley Campus (CVC.) C) To determine whether a permanent CSU Campus in Coachella Valley will motivate students from College of the Desert (COD) to get their bachelor's degree locally. D) To identify the degree programs in which COD students are most interested-in. E) To determine whether ethnicity (Hispanic students are the target group) plays a role in the students' choice of degree program. For purpose of this study literature pertaining to development of California State University, San Bernardino, and development of CSU off-campus centers was reviewed. Two hundred and thirty one students attending the spring 1999 semester at College of the Desert provided the data for this study."

Palm oil is a growing market, and environmental and social concerns have led to a global demand of sustainable palm oil. In this study I investigate the certification process of the Roundtable of Sustainable Palm Oil (RSPO) from the experiences of independent smallholders. I perform interviews and observations in two independent smallholder associations in the Riau province in Indonesia who are in the end of the RSPO certification process. What I find is that most smallholders have extrinsic motivators (an increase in price) for wanting to join the certi fication, but that a few smallholders express intrinsic motivators as well (a care for the environment). I find that the certification process is creating a lot of changes to the agricultural practices of the smallholders, mainly regarding harvest, fertilisation, pesticide usage, and pruning. The challenges that the independent smallholders experience mainly regard their knowledge, level of organisation, institutional support, fertilisation, and documentation. I find that many of the smallholders use traditional knowledge while the RSPO is an organisation that mainly use modern knowledge, and I claim that some of the dif ficulties that independent smallholders experience when certifying derives from this collision of knowledge systems. Lastly, I claim that the organisation is an expression of modernity and risk society, and that the rise of voluntary sustainability certi fications the last decade can be seen as a response to the modern risk of climate change.

Palmar flexion crease matching is a method for verifying or establishing identity. New methods of palmprint identification, that complement existing identification strategies, or reduce analysis and comparison times, will benefit palmprint identification communities worldwide. To this end, this thesis describes new methods of manual and automated palmar flexion crease identification, that can be used to identify palmar flexion creases in online palmprint images. In the first instance, a manual palmar flexion crease identification and matching method is described, which was used to compare palmar flexion creases from 100 palms, each modified 10 times to mimic some of the types of alterations that can be found in crime scene palmar marks. From these comparisons, using manual palmar flexion crease identification, results showed that when labelled within 10 pixels, or 3.5 mm, of the palmar flexion crease, a palmprint image can be identified with a 99.2% genuine acceptance rate and a 0% false acceptance rate. Furthermore, in the second instance, a new method of automated palmar flexion crease recognition, that can be used to identify palmar flexion creases in online palmprint images, is described. A modified internal image seams algorithm was used to extract the flexion creases, and a matching algorithm, based on kd-tree nearest neighbour searching, was used to calculate the similarity between them. Results showed that in 1000 palmprint images from 100 palms, when compared to manually identified palmar flexion creases, a 100% genuine acceptance rate was achieved with a 0.0045% false acceptance rate. Finally, to determine if automated palmar flexion crease recognition can be used as an effective method of palmprint identification, palmar flexion creases from two online palmprint image data sets, containing images from 100 palms and 386 palms respectively, were automatically extracted and compared. In the first data set, that is, for images from 100 palms, an equal error rate of 0.3% was achieved. In the second data set, that is, for images from 386 palms, an equal error rate of 0.415% was achieved.
