    Notes: Between 1991 and 1993, Alaska harbor porpoise (Phocoena phocoena) abundance was investigated during aerial surveys throughout much of the coastal and offshore waters from Bristol Bay in the eastern Bering Sea to Dixon Entrance in Southeast Alaska. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Survey data indicated densities of 4.48 groups/100 km2, or approximately 3,531 harbor porpoises (95% C. I. 2,206-5,651) in Bristol Bay and 0.54 groups/100 km2, or 136 harbor porpoises (95% C. I. 11-1,645) for Cook Inlet. Efforts off Kodiak Island resulted in densities of 1.85 groups/100 km2, or an abundance estimate of 740 (95% C. I. 259-2,115). Surveys off the south side of the Alaska Peninsula found densities of 2.03 groups/100 km2 and an abundance estimate of 551 (95% C. I. 423-719). Surveys of offshore waters from Prince William Sound to Dixon Entrance yielded densities of 4.02 groups/100 km2 and an abundance estimate of 3,982 (95% C. I. 2,567-6,177). Combining all years and areas yielded an uncorrected density estimate of 3.82 porpoises per 100 km2, resulting in an abundance estimate of 8,940 porpoises (CV = 13.8%) with a 95% confidence interval of 6,746-11,848. Using correction factors from other studies to adjust for animals missed by observers, the total number of Alaska harbor porpoises is probably three times this number.

    Notes: New technologies integrated New Zealand into the international economy after the 1960s. State investment in air services, international telecommunications, and container shipping enhanced access to overseas markets. They prepared the nation for the shock of Britain's entry into the European Economic Community. Yet state-owned services were not responsive to demand and were often slow to lower the cost of conducting business between New Zealand and the outside world. This paper suggests that the deregulation and privatization of government-owned enterprises after 1984 quickly reduced the cost of distance, accelerating the globalization of New Zealand.

    Notes: 1. During late spring 1993–1995, the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) sampled 490 wadeable streams in the mid-Atlantic Highlands (MAH) of the U.S. for a variety of physical, chemical and biological indicators of environmental condition. We used the resulting data set to evaluate the importance of differing levels of macroinvertebrate taxonomic resolution in bioassessments by comparing the ability of family versus genus to detect differences among sites classified by type and magnitude of human impact and by stream size. We divided the MAH into two physiographic regions: the Appalachian Plateau where mine drainage (MD) and acidic deposition are major stressors, and the Ridge and Valley where nutrient enrichment is a major stressor. Stream sites were classified into three or four impact classes based on water chemistry and habitat. We used stream order (first to third Strahler order) in each region as a measure of stream size. Ordination, 2 × 2 chi-square and biotic metrics were used to compare the ability of family and genus to detect differences among both stressor and size classes.2. With one notable exception, there were only a small number of different genera per family (interquartile range = 1–4). Family Chironomidae, however, contained 123 different genera. As a result, significant information loss occurred when this group was only classified to family. The family Chironomidae did not discriminate among the predefined classes but many chironomid genera did: by chi-square analysis, 10 and 28 chironomid genera were significant in discriminating MD and nutrient impacts, respectively.3. Family and genus data were similar in their ability to distinguish among the coarse impacts (e.g. most severe versus least severe impact classes) for all cases. Though genus data in many cases distinguished the subtler differences (e.g. mixed/moderate impacts versus high or low impacts) better than family, differences in significance levels between family and genus analyses were relatively minor. However, genus data detected differences among stream orders in ordination analyses that were not revealed at the family level. In the ordinations, both family and genus levels of analysis responded to similar suites of environmental variables.4. Our results suggest that identification to the family level is sufficient for many bioassessment purposes. However, identifications to genus do provide more information in genera-rich families like Chironomidae. Genus or finer levels of identification are important for investigating natural history, stream ecology, biodiversity and indicator species. Decisions about the taxonomic level of identification need to be study specific and depend on available resources (cost) and study objectives.

    Notes: This paper reports on young adults' expectations and perceptions of online retail banking information. A combination of qualitative and quantitative research was used. Focus groups proved valuable in eliciting criteria grounded in the experience of users of bank Web sites. The subsequent questionnaire survey allowed the measurement of gaps between perceptions and expectations. The results indicate that respondents expect bank Web sites to be easy to use and to provide them with basic account/product details. These features are valued more than the technological aspects. Yet, perceptions of actual information provision differ. While basic account and price information is perceived to be provided, certain features are perceived to be less prevalent, rendering bank Web sites ineffective at aiding consumer decision making. The research questions the role of the Internet in information provision and suggests how banks can improve their Web sites to assist consumer decision making.

    Notes: This paper uses the metaphor of the movie classic the Wizard of Oz to represent the online experiences of young adults. Just like the twister that turns Dorothy's world upside, down the Internet has arrived to transform our black and white lives into the Technicolor hyper-reality of the Land of Oz. What are the consequences for young Dorothies of today when they explore the yellow brick information superhighway? Phenomenologically informed qualitative research was used to explore the Internet experiences of older adolescents and young adults. The findings identify, financial, temporal, social, logistical and emotional barriers and indicate that although the Internet is an intrinsic facet of young adults' lives, it falls well short of an obsession. The implications are that marketing practitioners need to pay closer attention to the genuine fears and concerns directed at the Internet rather than assuming that young adults' responses are enthusiastic and positive.

    Notes: The use of a buffer system based on N-[2-hydroxyethyl]piperazine-N′-[2-ethanesulfonic acid] (HEPES), in conjunction with standard Gourlay's culture medium was investigated for the growth and maintenance of Mycoplasma mycoides subsp. mycoides SC vaccine strain T144. When the initial pH of the culture medium was adjusted to 8.0, 0.075 M HEPES–NaOH was found to be sufficient to prevent the pH falling below 7.1 at any stage during the growth cycle, even in the presence of 0.5% glucose. Compared to growth in standard unbuffered Gourlay's medium, the final culture titre was found to be one log10 higher, at 1011 colour changing units (CCU) per ml, and considerably extended culture survival was observed at 37°C. The titre remained above 1010 CCU ml−1 for 4 days, and above 108 CCU ml−1 in excess of 1 month. After 4 month's storage at 37°C the titre had fallen to 5×104 CCU ml−1. In contrast, no viable bacteria could be detected in standard unbuffered medium 3 days after the onset of stationary phase, at which point the pH had dropped to 5.4. No significant difference in growth rate between the two media was observed. Adoption of a HEPES–NaOH buffer system by African vaccine manufacturers should require minimal changes to current formulations and procedures, and should enhance both the final titre and thermostability of freeze-dried and liquid broth vaccines against contagious bovine pleuropneumonia (CBPP).

    Notes: The molecular genetic basis of high-frequency serotype 3 capsule phase variation in Streptococcus pneumoniae (the pneumococcus) was investigated. Pneumococci were grown in sorbarod biofilms at 34°C to mimic nasopharyngeal carriage. Different type 3 pneumococci commonly associated with invasive disease generated apparently random tandem duplications of 11–239 bp segments within the cap3A gene of the type 3 capsule locus. These duplications alone were found to be responsible for high-frequency capsule phase variation, in which (phase off) acapsular variants possessed duplications within cap3A, and (phase on) capsular revertants possessed wild-type cap3A genes, indicating the precise excision of the duplication. Additionally, the frequency of phase reversion (off to on) was found to exhibit a linear relationship between (log) frequency of reversion and (log) length of duplication. This apparently random duplication giving rise to phase variation is in stark contrast to the ‘preprogrammed’ contingency genes in many Gram-negative organisms that possess homopolymeric sequence repeats or motifs for site-specific recombination.
