Patterns of faunal change at an upper Cambrian trilobite extinction event, Nolichucky Formation, Tennessee and Virginia

During the Upper Cambrian there were three mass extinctions, each of which eliminated at least half of the trilobite families living in North American shelf seas. The Nolichucky Formation preserves the record of one of these extinction events at the base of the Steptoean Stage. Sixty-six trilobite collections were made from five sections In Tennessee and Virginia. The lower Steptoean faunas are assigned to one low diversity, Aphelaspis-dominated biofacies, which can be recognized in several other parts of North America. In Tennessee, the underlying upper Marjuman strata contain two higher diversity biofacies, the Coosella-Glaphyraspis Biofacies and the Tricrepicephalus-Norwoodiid Biofacies. At least four different biofacies are present in other parts of North America: the Crepicephalus -Lonchocephalus Biofacies, the Kingstonia Biofacies, the Cedaria Biofacies, and the Uncaspis Biofacies. A new, species-based zonation for the Nolichucky Formation imcludes five zones, three of which are new. These zones are the Crepicephalus Zone, the Coosella perplexa Zone, the Aphelaspis buttsi Zone, the A. walcotti Zone and the A. tarda Zone. The Nolichucky Formation was deposited within a shallow shelf basin and consists largely of subtidal shales with stormgenerated carbonate interbeds. A relative deepening is recorded In the Nolichucky Formation near the extinction, and is indicated In some sections by the appearance of shale-rich, distal storm deposits above a carbonate-rich, more proximal storm deposit sequence. A comparable deepening-upward sequence occurs near the extinction in the Great Basin of southwestern United States and in central Texas, and this suggests a possible eustatic control. In other parts of North America, the extinction IS recorded In a variety of environmental settings that range from near-shore to slope. In shelf environments, there is a marked decrease in diversity, and a sharp reduction in biofacies differentiation. Although extinctions do take place in slope environments, there IS no net reduction in diversity because of the immigration of several new taxa.

Studies on oxamyl : analytical method development and investigation of fate in peach seedlings and corn seeds

A high performance liquid chromatographic method employing two columns connected in series and separated~y·a.switching valve has been developed for the analysis of the insecticide/ nematicide oxamyl (methyl-N' ,N'-dimethyl-N-[(methylcarbamoyl) oxy]-l-thiooxarnimidate) and two of its metabolites. A variation of this method involving two reverse phase columns was employed to monitor the persistence and translocation of oxamyl in treated peach seedlings. It was possible to simultaneously analyse for oxamyl and its corresponding oxime (methyl-N',N'-dimethyl-N-hydroxy-l-thiooxamimidate}, a major metabolite of oxamyl in plants, without prior cleanup of the samples. The method allowed detection of 0.058 pg oxamyl and 0.035 p.g oxime. On treated peach leaves oxamyl was found to dissipate rapidly during the first two-week period, followed by a period of slow decomposition. Movement of oxamyl or its oxime did not occur in detectable quantities to untreated leaves or to the root or soil. A second variation of the method which employed a size exclusion column as·the first column and a reverse phase column as the second was used to monitor the degradation of oxamyl in treated, planted corn seeds and was suitable for simultaneous analysis of oxamyl, its oxime and dimethylcyanoformamide (DMCF), a metabolite of oxamyl. The method allowed detection of 0.02 pg oxamyl, 0.02 p.g oxime and 0.005 pg DMCF. Oxamyl was found to persist for a period of 5 - 6 weeks, which is long enough to permit oxamyl seedtreatment to be considered as a potential means of protecting young corn plants from nematode attack. Decomposition was found to be more rapid in unsterilized soil than in sterililized soil. DMCF was found to have a nematostatic effect at high concentrations ( 2,OOOpprn), but at lower concentrations no effect on nematode mobility was observed. Oxamyl, on the other hand, was found to reduce the mobility of nematodes at concentrations down to 4 ppm.

Effect of pH on non-photochemical quenching in spinach photsystem 2 particles as measured by picosecond fluorescence decay kinetics

Single photon timing was used to study picosecond chlorophyll a fluorescence decay kinetics of pH induced non-photochemical quenching in spinach photosystem 2 particles. The characteristics of this quenching are a decrease in chlorophyll a fluorescence yield as well as a decrease in photochemistry at low pH. Picosecond kinetics of room temperature fluorescence temporally resolve the individual components of the steady state fluorescence yield into components that are related to primary energy conversion processes in photosystem 2. Four components were resolved for dark adapted (Fo), light saturated (Fm), and chemically reduced (Nadithionite) photosystem 2 reaction centres. The fastest and slowest components, indicative of energy transfer to and energy capture by the photosystem 2 reaction centre and uncoupled ("dead") chlorophyll, respectively, were not affected by changing pH from 6.5 to 4.0. The two intermediate components, indicative of electron transfer processes within the reaction centre of photosystem 2, were affected by the pH change. Results indicate that the decrease in the steady state fluorescence yield at low pH was primarily due to the decrease in lifetime and amplitude of the slower of the intermediate components. These results imply that the decrease in steady state fluorescence yield at low pH is not due to changes in energy transfer to and energy capture by the photosystem 2 reaction centre, but is related to changes in charge stabilization and charge recombination in the photosystem 2 reaction centre.

Perennial negotiations/elemental encounters autoethnographic perspectives on approaching food sovereignty

This thesis uses a multifaceted process to engage with the topic of food sovereignty in California. It employs diverse methods, including critical and creative prose, photography, autoethnographic mixed media, storytelling and poetry. I am particularly concerned with the " " challenges of approaching food sovereignty, a radical praxis that combines subsistence practices with anti-capitalist resistance, while in my own "skin," which is thoroughly embedded in white, urban, middle classed culture and in corltextualizing ecological relationshipslkinships via cultural, historical and economic trajectories. The project utilizes a processual methodlology drawing substantially from the work of Brian Massumi to explore these issues through four creative narrative pieces which coalesce around the elemental metaphors of air, fire, water and earth. Following Deleuze and Guatarri's concept ofrhizomatic plateaus, the thesis narratives are comprised of many non-hierarchical layers and can be read from many angles. Each is offered "in process" rather than as a finished piece, thus practically validating the concept of the ongoing work of research and suggesting the equally omnipresent possibility of change and mutation in the formation relationally based knowledges. Cultivating ecological ethic and healing on multisensory levels, as well as commitment to emergent and re-productivist worldviews are goals of this project's research.

John Smith, M.P fonds, 1930, 1949-1950, 1954, 1957-1962, n.d.

John Smith (1894-1977), son of Daniel Smith and Annie Douglas was a native of Scotland, immigrating to Canada in 1913. He first worked as a coach builder, then as a carpenter, finally developing his own contracting business. During WWI he served overseas with the 10th Battery, RCA as a sergeant. In 1924 Smith married Jean Wood, and together they had a daughter Irene (Hugh Langley). Smith first entered politics in 1940 serving as an alderman for the next 11 years. In 1954 he was elected mayor of the city of St. Catharines, and was twice returned to office by acclamation, serving until 1957 when he successfully ran as the Progressive Conservative candidate representing Lincoln County in the federal election. He won the election by a 10 000 vote majority. He served his constituents in Ottawa until he was defeated in the 1962 election. After leaving politics Mr. Smith was active in his community. He spearheaded the establishment of the St. Catharines Museum, and then was appointed its first director in 1966, serving in that capacity until 1972. He was an active member of the board of governors of the St. Catharines General Hospital and a life member and former president of the Lincoln County Humane Society. In 1971 he was voted Citizen of the Year for the city of St. Catharines. John Smith died on February 8, 1977 and was buried at Victoria Lawn Cemetery.

Search engine advertising in web retailing : an efficiency analysis

This study examines the efficiency of search engine advertising strategies employed by firms. The research setting is the online retailing industry, which is characterized by extensive use of Web technologies and high competition for market share and profitability. For Internet retailers, search engines are increasingly serving as an information gateway for many decision-making tasks. In particular, Search engine advertising (SEA) has opened a new marketing channel for retailers to attract new customers and improve their performance. In addition to natural (organic) search marketing strategies, search engine advertisers compete for top advertisement slots provided by search brokers such as Google and Yahoo! through keyword auctions. The rationale being that greater visibility on a search engine during a keyword search will capture customers' interest in a business and its product or service offerings. Search engines account for most online activities today. Compared with the slow growth of traditional marketing channels, online search volumes continue to grow at a steady rate. According to the Search Engine Marketing Professional Organization, spending on search engine marketing by North American firms in 2008 was estimated at $13.5 billion. Despite the significant role SEA plays in Web retailing, scholarly research on the topic is limited. Prior studies in SEA have focused on search engine auction mechanism design. In contrast, research on the business value of SEA has been limited by the lack of empirical data on search advertising practices. Recent advances in search and retail technologies have created datarich environments that enable new research opportunities at the interface of marketing and information technology. This research uses extensive data from Web retailing and Google-based search advertising and evaluates Web retailers' use of resources, search advertising techniques, and other relevant factors that contribute to business performance across different metrics. The methods used include Data Envelopment Analysis (DEA), data mining, and multivariate statistics. This research contributes to empirical research by analyzing several Web retail firms in different industry sectors and product categories. One of the key findings is that the dynamics of sponsored search advertising vary between multi-channel and Web-only retailers. While the key performance metrics for multi-channel retailers include measures such as online sales, conversion rate (CR), c1ick-through-rate (CTR), and impressions, the key performance metrics for Web-only retailers focus on organic and sponsored ad ranks. These results provide a useful contribution to our organizational level understanding of search engine advertising strategies, both for multi-channel and Web-only retailers. These results also contribute to current knowledge in technology-driven marketing strategies and provide managers with a better understanding of sponsored search advertising and its impact on various performance metrics in Web retailing.

Sean O'Sullivan fonds

Sean O’Sullivan was born in Hamilton, Ontario, in 1952. At an early age, he demonstrated an interest in politics. A chance meeting with John Diefenbaker in 1963, when Sean was just 11 years old, marked the beginning of his involvement with the Progressive Conservative Party. Diefenbaker became a mentor to him, and the two exchanged correspondence for many years. Sean became an active member of the Party, and his political career took off quickly. In 1965, he was elected to the executive of the Hamilton Area Young Progressive Conservatives, in 1968 was elected President, and also served as Youth Director for Diefenbaker’s re-election campaign. In 1970 he was elected President of the Ontario Young Progressive Conservatives, and in 1971 became Youth Adviser to Premier William Davis. Later that year, Diefenbaker chose Sean to be his Executive Assistant. In addition to his political activities, Sean enrolled at Brock University in 1969 to study political science. In 1972, he resigned as Diefenbaker’s assistant in order to run as a candidate for Hamilton-Wentworth in the federal election that year. At just 20 years of age, Sean was the youngest MP elected to the House of Commons. While working as an MP, Sean continued his studies at Brock University part-time, graduating with distinction. After being re-elected in 1974, he rose to greater prominence when he succeeded in having a private member’s bill passed making the beaver one of Canada’s national symbols. In 1977, he resigned as MP in order to pursue religious studies and become a Catholic priest. After completing four years of studies at the Irish College of Rome’s Gregorian University, Sean was ordained a priest in Toronto in 1981. In July, 1982, he was appointed Director of Vocations (full-time recruiter) for the archdiocese of Toronto. In this capacity, he implemented a controversial and widely publicized campaign to recruit priests. The recruitment succeeded in generating interest in the priesthood, doubling the number of students in the archdiocese. He was one of the founding members of Serra House, a residence for students considering the priesthood. After his term as Vocations Director ended in 1985, O’Sullivan became publisher of The Catholic Register, a weekly church newspaper. That same year, he was awarded an honorary doctorate from Brock University. In January 1987, he was appointed a Member of the Order of Canada. Later that year, he submitted a report to the Attorney General of Ontario, titled You’ve got a Friend, after conducting an independent review of Advocacy for Vulnerable Adults in Ontario at the request of the government. In 1983, O’Sullivan was diagnosed with leukemia. The disease went into remission after treatment, but was incurable. In 1989, he had a bone marrow transplant at Princess Margaret Hospital in Toronto, but died shortly afterwards. He was 37 years old. A memorial fund was established in his name, and included contributions from prominent business, church and political leaders such as Prime Minister Brian Mulroney, Toronto Sun Chairman Doug Crieghton and His Eminence G. Emmett Carter. The O’Sullivan family requested that Brock University be the beneficiary of the proceeds of the campaign.

Schram Family of Wainfleet Township documents, 1839-1901 (not inclusive)

George William Schram (1809-1885), son of Garrett Schram and Leah Van Etten, married Orpha Pearson on Nov.13, 1835. His son Marsena John Schram (farmer) was born in May of 1840, in Canada. He died on Nov. 17, 1926 in Wexford County, Michigan. He was married in 1867 to Sarah (1825-1887).Marsena married again on April 18, 1910 to Ann Clarinda Warner (1861-1924). He was working as a carpenter at this time. They had another son, William who was born about 1838 and he married Sabina Chambers on Jan. 21, 1862. The 1861 census for Wainfleet lists siblings of Marsena John Schram as Sarah J. (age 14), Georgiana (age 5), and William (age 21). The Schrams lived on Concession 5 and owned approximately 144 acres of land. David Thompson was born Feb. 4, 1873 and died Feb. 19, 1951. He married Sally Ann Wilson on Sept. 7, 1825 in Pelham. She died about 1840 in Indiana Ontario (near Cayuga). Lemuel Victor Hogue was born Dec.1, 1854 and died Jan. 12, 1929.

Proposal for Construction of Brock’s Monument, Queenston, newspaper fragment, 1824

Brock’s Monument is owned by Parks Canada and maintained by the Niagara Parks Commission in collaboration with the Friends of Fort George and Niagara National Historic Sites. It is located in Queenston Heights Park atop the Niagara Escarpment. On March 14, 1815, Parliament passed an act to erect a monument to the memory of General Isaac Brock. A design by engineer Francis Hall was selected. He envisioned a 135 ft. tall Tuscan column, made out of stone with a winding staircase inside. By the spring of 1824, work had begun on the monument. In June of that year, the cornerstone was laid and William Lyon Mackenzie was in attendance at the ceremony. It was on October 13th, 1824 (the anniversary of Brock’s death) that 6000 people traveled to Queenston to inter the remains of Brock and Lieutenant-Colonel Macdonell. This was the second burial for both. After 3 years the tower had reached 135 feet, but there was no inscription at the base, the fence around the observation deck had not been installed and there was no statue of Brock. Hall submitted a plan to finish the statue, but he was turned down and a simple ornament was placed where the Brock statue should have been. A massive blast of gunpowder destroyed the monument in 1840. It is alleged that an American sympathizer with the Upper Canada Rebellion set off the blast. Brock and Macdonell’s bodies were reburied in the Hamilton Family Cemetery in Queenston. The present monument was rebuilt in 1853. William Thomas (designer of St. Michael’s Cathedral in Toronto) was the architect. Brock and Macdonell were once again laid to rest in separate vaults at the statue. In 1968, Brock’s Monument was declared a national historical site. In 2005, it was closed to the public due to safety concerns, but it reopened in 2010.

Alloparental care in a solitary bee

Research into the evolutionary origins of sociality in insect colonies is changing emphasis from understanding how eusociality is maintained to how insects transition from solitary to social lifestyles. The pygmy carpenter bees (Ceratina spp.) offer an excellent model for investigating such factors as they have been historically thought of as solitary but have recently been shown to be socially polymorphic, which may indicate that they are currently in a transitive phase. By utilizing behavioural observation and experimental removal protocols, I show that extended parental care, as well as sibling care in Ceratina calcarata plays an important role in offspring development. I found, upon removal of the mother, that specifically produced ‘dwarf’ female offspring take over parental care roles in the nest. The existence of alloparental care and generational overlap suggests that although they are classified as solitary bees, C. calcarata possess the prerequisite behavioural repertoire for sociality.
