In August 1959 Pacific Marine Station (P.M.S.) located at Dillon Beach, began a program of oceanographic study as a member of the California Cooperative Oceanic Fisheries Investigations (C.C.O.F.I.). The program continued throughout the summer of 1963 and consisted of a monthly hydrographic station and sampling the plankton at the head of Bodega Submarine Canyon, located twenty-five miles west of Bodega Bay. Two plankton tows were taken on each ocean run. One of the samples, along with collection and hydrographic data, was sent to Scripps Institute of Oceanography. The other sample was retained at P.M.S. and constitutes the material for the present study. Pelagic gastropods were present in every tow in varying numbers and species. Two groups, pteropods and heteropods, were found in the samples. One species of pteropod, Limacina helicina, was the dominant member in all of the tows and occurred during the entire year. Little work has been done on the pelagic gastropods of the North Pacific. The information available has been mainly compiled by Tesch in the Dana Reports and McGowan (1960). Taxonomically the group has been extensively studied, but little is known about the life cycles, size ranges, growth rates, physiology, behavior, distribution and abundance. No previous study on the pelagic gastropods collected by P.M.S. has been made. This paper is a discussion of the pelagic gastropods collected over a period of four years. It is the purpose of this study to identify, examine, and present information of the local specimens collected by Pacific Marine Station.

Work on the copepoda parasitizing anoidiens has been relatively extensive in Europe, loss so on the East Coast of the United States and negligible on the West Coast. of this work, a major portion has been concerned with the solitary ascidians, while the colonial or compound forms have been largely neglected. The apparent lack of interest in copepods parasitizing compound be attributed to the manliness of the animals, their associations with both Zooids and the colonial matrix which makes dissection difficult and the chaotic condition of their taxonomy.

Two common limpets, Collis~ (Acmaea) digitalis and Collisella (Acmaea) scabra have overlapping distributions in the upper int.ertidal .spray zone. Haven (1971) found that Q. digitalis is more abundant on vertical surfaces while Q. scabra dominates horizontal surfaces. He assumed this preference to be due to differential abilities to withstand desiccation. In this study I report field work demonstrating a high correlation between the-ratio of abundance of Q. digitalis/ Q. scabra and angle of slope of substrate. Length (mm) of Q. scabra declines linearly with angle, but Q. digitalis shows no such trends. Results of laboratory measurements of angle of substrate and small and large members of the species do not alone explain the size distribution and abundance relationships found be·tween the two species in the field .• Although resistance to desiccation may play a part in determining distribution and abundance, especially in the upper intertidal, it is clear that other factors may be important, such as food resources. Fecal pellets were used as a technique to study food resource partioning. Limpet size and abundance is related to the availability of microalgae on a particular slope of substrate. Differences in the amount of movement between the two species may be. related to time and distance traveled in foraging for food. The ratio of abundances of these limpets and its relation to substrate angle needs to be studied from the point of view of competitive interactions with respect to food resource partioning, since these species seem to have tolerances to desiccation greatly exceeding environmental stress conditions.

Various studies indicate the acmaeid limpet species Collisella digitalis, Collisella pelta and Notoacmea scutum inhabit different vertical zones in the rocky-intertidal region. At Sunset Bay, Oregon, Shotwell (1950) found that C. digitalis was situated in the upper intertidal C. pelta inhabited the mid-intertidal and N. scutum was located in the mid to lower zone in the rocky-intertidal region. Frank (1965) observed the same distribution patterns at Coos Bay, Oregon as did the author in the rocky-intertidal region near Dillon Beach, California. Species distributions in the rocky-intertidal region are thought to be limited from above by physical stress and from below by predation or competition (Connell 1970; Dayton 1971; Vermeij 1972; Paine 1974; Bertness 1977). The purpose of the present study was to investigate effects of the predators Pisaster ochraceus, Cancer antennarius and Pachygrapsus crassipes on the distributions of the three acmaeid limpet species particularly with respect to their lower limits.

有關離散資料的判別分析問題，在各種應用領域內扮演著相當重要的角色。例如醫療 診斷、消費者購買行為之研究等等。然而在研究分析的過程當中，因為少數離散變數 （含二個以上的階數（level ））的增加即能引起狀態（state ）的遽增，從而導致 模型建立的複雜性以及抽樣估計上種種難以克服的困難。因此在上述情況之下，對離 散判別模型之建立與分析的問題便特別值得我們重視。 本文基於此種需要，期能研究一些”最佳”變數組之尋求的方法並且找出各種方法的 適用狀況及優劣得失。最重要的是設計更優良迅速的電腦通式，以加強各種方法之使 用強度。 本文結構預計分五章討論： 第一章 緒論：將詳述研究動機及目的，並闡述本研究之結構與貢獻。 第二章 判別分析的基本理論：探討有關離散資料方面之判別分析法。 第三章 變數選取之理論與方法：最主要是探討Goldstein 與Rabinowitz〔１９７５ 〕提出的以判別值距離為基礎之變數選取法，及Goldstein 和Dillon〔１９７７〕發 展的Forward 變數選取法，和兩者之優劣點。並改進原始程式，以應用在套裝軟體之 上。 第四章 模擬分析：利用模擬技術探討各方法的適用狀況。 第五章 結論：在此章將提出研究之結果。

Master of Science / Horticulture, Forestry, and Recreation Resources / Ted T. Cable / Dillon Nature Center has a wide variety of exhibits that teach the public about the natural resources of Kansas. The purpose of my study was to conduct an exploratory study about the effectiveness of two key exhibits in the nature center (Underground Theater and Tornado), as well as evaluate the use of Quick Response Code or QR codes along one of the trails. A visitor survey was used to collect these data over 30 3- hour sampling periods. One hundred and ninety-five visitors were surveyed during the extent of my study. Fifty-four of those who were surveyed went into the Underground Theater exhibit and 47 went into the Tornado exhibit. I concluded that the Underground Theater exhibit was successful in providing useful information to the visitor, whereas the Tornado exhibit provided little useful information to the visitor. Visitors slightly preferred the use of QR codes along the trail even though the actual use was low. This study indicated that the type of exhibit greatly impacts what the visitor takes away from the exhibit. I also showed that it is likely people prefer newer technology to be available at the nature center. These findings provided the management and staff of Dillon Nature Center with information to guide their interpretive-planning efforts.

Studies on trematodes of marine organisms of the Pacific Coast have been of a scattered and fragmentary nature. J. Stafford (1904) collected and described a number of trematodes from fishes of the north Pacific, but, in his historical survey, Manter (1926) fails to mention specifically any studies covering the waters south of Canada. More recently, in the United States, several contributions to the field have been made by Dr. John E. Guberlet at the University of Washington and at the College of the Pacific by Dr. Alden Noble, under whose guidance this study was made. James Park (1937) revised the genus Podocotyle and added eight new species .from Dillon Beach, California. Descriptions of individual trematodes have been made by various other investigators. The investigation covered by this paper was begun during the summer or 1946 at the Pacific Marine Station.

In the present study, information concerning morphology, ecology, fertilization and larval development of three sympatric species of Eusonus is presented. Morphological similarities are reviewed in part I. These similarities correspond with significant lack of variation found in larval development (part IV). Despite these similarities, as well as the ability to cross fertilize their species, the ecological and reproductive isolating mechanisms presented in part II and II provide a positive indication of the existence of three biologically distinct species. A comparative discussion reviews the efficacy of morphological criteria in differentiating the three closely related Euzonus species.

Den här uppsatsen har som syfte att undersöka på vilka sätt läsning framställs och vilka funktioner läsning fyller i Markus Zusaks uppmärksammande roman The Book Thief (2005). För att besvara detta syfte ställs frågeställningarna: Hur förhåller sig protagonisten Liesel till läsning och vad betyder det för henne? På vilket sätt förstärks romanens lästematik med hjälp av dess berättarteknik? Analysen är uppdelad i två delar. För att besvara den första frågeställningen har en tematisk läsning med inriktning på läsning utförts, genom att presentera citat från romanen för att undersöka vilka funktioner den fiktiva läsningen fyller i The Book Thief. Den andra delen av analysen som besvarar den andra frågeställningen utgår från begreppen palimpsest, mise en abyme och hypertextualitet.  Resultatet av undersökningen visar att läsning fyller fyra centrala funktioner för protagonisten Liesel: läsning som terapi och trygghet, social aktivitet, revolutionerande handling och makt samt förstärkning av livet och verklighetsflykt.  Med hjälp av berättartekniska grepp som mise en abyme och palimpsest skapas ett metaperspektiv i romanen. Romanen The Book Thief handlar om flickan Liesel och är baserad innehållsligt på hennes egenskrivna bok. Romanen kan ses både som en bokstavlig och bildlig palimpsest. Bokstavligt eftersom romanen innehåller illustrationer som visar karaktären Maxs berättelse som är placerad på övermålade sidor av Mein Kampf. Det kan ses som en bildig palimpsest eftersom berättaren Döden tillåter läsaren att se igenom hans berättelse, då citat från Liesels bok presenteras. Detta bidrar till att förstärka romanens lästematik, då Döden som berättare uppmärksammar att han och Liesel både är läsare och berättare.

The Little San Bernardino Mountains (LSBM) Fault Set are N-S dextral faults, east of the restraining bend of the San Andreas Fault (SAF) in southern California, that may form a tectonic linkage between the SAF and the Eastern California Shear Zone. The NW LSBM are a complexly deformed structural domain characterized by the young N-S dextral faults and older NW-oriented Dillon Shear Zone faults. Before the 1992 Joshua Tree (Mw 6.1) and Landers (Mw 7.3) earthquakes, the rugged NW LSBM was the subject of few geologic studies. This bedrock mapping study has further delineated the geometry, distribution, and relative chronology of brittle structures. A 2015 NCALM award of 51 km2 of lidar imagery on Eureka Peak Fault was used to correct fault locations. Bedrock mapping in the epicentral areas of the 1992 Joshua Tree earthquake on Eureka Peak Fault and Landers aftershocks (Mw 5.7, 5.8) focused on the brittle structures of the evolving fault systems and potential connections with historic seismicity. The N-S dextral fault offsets from west to east are; Long Canyon (470 m), Wide Canyon (~150- 340 m), Eureka Peak (~ 225 m), California Riding Trail (850-965 m) and Deerhorn (105 m) faults with a cumulative offset of approximately 2 km. Dolomitic marble, clinopyroxene-hornblende skarn, garnet-epidote skarn and gabbro-diorite intruded by monzogranite are key lithologies used in determining offsets. Joshua Tree Fault, defined by seismicity by Kaven and Pollard (2013) is supported by additional mapped fault data. A “new” fault (Black Rock Canyon) links Wide Canyon and northern Eureka Peak faults. The distribution of aftershock seismicity plotted by depth and latitude along the N-S faults, a prominent broad seismicity trend and bedrock mapping are all consistent with interpreting the N-S faults as an incipient set of faults developing upward from a deeper through-going crustal shear zone. The seismicity since the onset of the Joshua Tree- Landers earthquake sequence on April 23, 1992, forms two distinct trends. Temporally these two trends occurred in sequence; first a N-propagating trend April 23- mid-June along Joshua Tree Fault from the Joshua Tree earthquake epicenter to north of the Pinto Mountain Fault, and secondly a prominent SE trend of Landers aftershocks (including Mw 5.7, 5.8) June 28 onwards, from the Landers earthquake epicenter, along Eureka Peak Fault to the SAF. AFT and (U-Th)/He thermochronology indicate an abrupt boundary on Long Canyon Fault between rapid uplift within ~ 12 km of the SAF and slower uplift more than 12 km north. This boundary is projected along the Dillon Shear Zone structural grain to the 1992 Joshua Tree earthquake epicenter on southern Eureka Peak Fault, dividing the N-striking faults into northern and southern domains. The 14.7 km hypocentral depth of the Joshua Tree earthquake coincides roughly with the depth of the NE dipping SAF intersection with Eureka Peak Fault, forming a hypothesized flower structure which is consistent with rapid uplift of the LSBM escarpment near the SAF. The LSBM Fault Set may be initiated by the upward migration of a through-going mid-crustal break and eastern migration of the current SAF trace bypassing the Big Bend slip impediment. Eureka Peak Fault with a slip rate of 10-20 mm/yr, is the proposed structure tectonically linking the SAF and the Eastern California Shear Zone.
