    Notes: . Miamiensis avidus, a marine scuticociliate, undergoes microstome to macrostome transformation. This process is induced by prey ciliates. the morphogenesis of this process was examined using scanning electron microscopy and light microscopy of quantitative protargol-stained specimens. Several stages are identified and described.

    Notes: . Metanophrys diminuta n. sp., a marine philasterine scuticociliate collected from the south Florida coast, was preserved for transmission electron microscopy using a mixed fixation technique. Rough endoplasmic reticulum profiles were found proximal to mitochondria and within mitochondrial fenestrations (or deep pockets). In longitudinal sections mitochondrial profiles appear to be very long, occupying almost the entire length of the cell. The micronucleus is roughly spherical to ovoid, semi-enclosed in the macronucleus. The oral polykinetid #1 is composed of two files of kinetosomes. The c segment of the oral dikinetid is composed of three to four kinetosomes. This species is the smallest within the genus Metanophrys.

    Notes: Miamiensis avidus is a marine polymorphic scuticociliate that undergoes microstome to tomite transformation when nutrients are depleted. This transformation takes place as a result of two consecutive divisions and does not involve a cyst. Tomitogenesis was induced by nutrient deprivation. When returned to nutrient medium tomites transformed into microstomes. Changes in population were noted at one-hour intervals. Tomites of Miamiensis avidus Ma/2 are compared to dispersal stages in other scuticociliates and hymenostomes.

    Notes: . Miamiensis avidus Ma/2 is a marine polymorphic scuticociliate. Eight strains of philasterine scuticociliates, currently in culture at the American Type Culture Collection (ATCC), were shown to produce a soluble factor that induces macrostomy in Ma/ 2: Miamlensis avidus (Ma and Ma/2), Paranophrys sp. (1–1), Parauronema acutum (110–3). Anophtyoides soldoi (116–1), Anophryoides sp. (33–8). Merunophrys sp. (113–8), and Paranophrys sp. (34–7). Of the strains tested, Paranophrys strain 1–1 showed the highest induction of transformation, although all eight strains showed statistically significant induction.

    Notes: Introduces the concept of a manufacturing strategy based on a serviceorientation. Traditional manufacturing strategies have often beendriven by cost minimization decisions and have encouraged theover-reliance by managers on inventories to satisfy demand. In today'sbusiness environment, a reliance on inventory is often not feasible.Suggests a reliance on capacity available to meet demand, as used by theservice industry. Such a strategy is in direct conflict with mostcost-accounting systems because of the absorption of overhead costsbased on direct labour. Proposes two alternatives for changing theaccounting system, to enhance the move towards the service-basedstrategy. Lastly, presents a case study of a US plant to illustrate theresults that a company adopting this approach should expect.

    Notes: Summary 1. A cDNA that encodes a Kex2-like prohormone convertase (PC) containing an active site similar to that of mammalian PC2 has been isolated fromC. elegans. Total RNA was isolated from a mixed population of strain BA713 worms. After poly-(A)-selection and reverse transcription, degenerate/nested polymerase chain reactions (PCR) were performed using primers based on conserved regions within the active sites of the known vertebrate and invertebrate endoproteases. 2. Two distinct 300-bp PCR products that shared homologies with the active sites of known Kex2-like endoproteases were isolated. These two PCR products were used to screen aC. elegans cDNA library. 3. The complete cDNA for a Kex2-like endoprotease, designated CELPC2, was isolated and determined to be 2527 bp in length. This size was confirmed by northern analysis. The deduced amino acid sequence for the CELPC2 cDNA is very similar to the known Kex2-like endoproteases, especially at conserved regions within the active sites, but not identical to any one of them. The strongest structural homology was to vertebrate and invertebrate PC2 sequences. 4.In situ hybridization suggests that CELPC2 is synthesized primarily in cells associated with the circumpharyngeal nerve ring and the dorsorectal ganglion.

    Notes: Abstract A household probability sample of 229 adults was interviewed four to seven months after the Sierra Madre earthquake (June 28, 1991; Los Angeles County). The study predicted psychological distress from these variables: demographics, traumatic event history, low magnitude event history, earthquake related threat perceptions, and earthquake related resource loss. Based on the Conservation of Resources (COR) stress model, it was predicted that resource loss would be central in predicting psychological distress. Three major hypotheses were supported: (1) resource loss was positively associated with psychological distress; (2) resource loss predicted psychological distress when other predictors were statistically controlled; and (3) resource loss was associated with mild to moderate elevations in of psychological distress. The findings support COR stress theory. Theoretical and practical implications are discussed.
