Designing a Culvert Management System for the Town of Spencer, MA
No full textTwenty-two road-stream crossings were assessed for the Town of Spencer, MA and the River and Stream Continuity Database. Each culvert, bridge, or dam was profiled to identify any constraints and possible considerations for future maintenance or replacement. A structural module was designed to assess the current condition of the crossings and work alongside the River and Stream Continuity Project, which does not have a structural component. The resulting analysis was presented to the attention of the Spencer Water Department

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Using optical fibre sensors for structural health monitoring of Tsing Ma Bridge
No full textOptical fibre sensors have been extensively employed as real-time damage detection tools in advanced aircraft and space vehicles. However, the practical applications of this kind of sensors to real civil engineering structures have not been widely adopted. A structural health monitoring system - Wind and Structural Health Monitoring System (WASHMS) for the Tsing Ma Bridge has been operated since the bridge commissioning in May 1997. This paper presents a study using fiber Bragg grating sensors to measure strain responses of the Tsing Ma Bridge and compare the results with those obtained from W ASHMS using traditional resistive strain gauges. The measurement results using FBG sensors were in excellent agreement with those acquired by WASHMS

Phytomyza notopleuralis Spencer
No full textPhytomyza notopleuralis Spencer (Figs. 58, 84) Material examined. MASSACHUSETTS: Berkshire Co., Great Barrington, 42.197870, -73.335897, 17.ix.2017, em. ~ 16.iv.2018, C.S. Eiseman, ex Cornus sericea, # CSE4416, CNC1144083–1144084 (1♁ 1♀). Host. * Cornaceae: Cornus sericea L. Leaf mine. (Fig. 84) Entirely linear, on the upper leaf surface; frass in somewhat liquidy strips along the sides. Puparium. Shining dark brown with paler brown intersegmental boundaries; formed outside the mine. Phenology and voltinism. Our specimens were collected as larvae in mid-September and emerged as adults the following spring. There is presumably at least one earlier generation; the only other known specimens were collected as adults on 3 June (Ontario) and 9 July (Michigan) (Spencer 1969; Spencer & Steyskal 1986). Distribution. USA: *MA, MI; Canada: ON (Spencer & Steyskal 1986). Comments. Neither Spencer (1969) nor Spencer & Steyskal (1986) made any statements about the possible relationships of Phytomyza notopleuralis to other Phytomyza. Winkler et al. (2009) indicated that it is near P. spinaciae Hendel, a Palearctic species mining leaves of Cynareae (Asteraceae) and forming a white puparium within the leaf, and placed it in the syngenesiae group. However, the leaf mine is identical with that of P. agromyzina Meigen, which feeds on various dogwoods including Cornus sericea, and the younger P. notopleuralis may eventually prove to be its junior synonym. External morphology is nearly identical, excluding the presence of a strongly pale yellow notopleuron in P. notopleuralis (Fig. 58) (yellowish tint with margins yellower in P. agromyzina), and the genitalia (Spencer 1969: Fig. 470) only differ in that the distiphallus of P. agromyzina is basally straight (not shallowly curved) and sometimes slightly abbreviated; the apex of the distiphallus is also sometimes a bit straighter. The phallus of P. agromyzina illustrated in Spencer (1969: Fig. 395) shows the distiphallus as a simple membranous lobe without the narrow, apically forked and medially deviated sclerotized band; this is apparently an artifact of illustration, as this structure is present in all dissected material examined at the CNC.Published as part of Eiseman, Charles S., Lonsdale, Owen, Linden, John Van Der, Feldman, Tracy S. & Palmer, Michael W., 2021, Thirteen new species of Agromyzidae (Diptera) from the United States, with new host and distribution records for 32 additional species, pp. 1-68 in Zootaxa 4931 (1) on pages 36-37, DOI: 10.11646/zootaxa.4931.1.1, http://zenodo.org/record/454533
Liriomyza asclepiadis Spencer
No full textLiriomyza asclepiadis Spencer (Fig. 134) Material examined. KANSAS: Riley Co., Konza Prairie Biological Station, 3.vii.2015, em. by 19–20.vii.2015, C.S. Eiseman, ex Asclepias viridis, #CSE1741, CNC654491–654493 (1♂ 2♀); MASSACHUSETTS: Franklin Co., Northfield, 42.646572, -72.428259, 21.vi.2016, em. 6–10.vii.2016, C.S. Eiseman, ex Asclepias exaltata, #CSE2710, CNC654109–654111 (2♂ 1♀); Orange, along Shingle Swamp Brook (42.561394, -72.299578), 11.viii.2016, em. 26–29.viii.2016, C.S. Eiseman, ex Asclepias incarnata, #CSE2952, CNC638897 (1♂). Hosts. Apocynaceae: Asclepias * exaltata L., A. incarnata L., A. syriaca L., A. * viridis Walter (Spencer 1969). The record of A. speciosa Torr. (Spencer 1969; Lonsdale 2017) refers to Liriomyza subasclepiadis Spencer (Spencer & Steyskal 1986). See comments for other possible hosts. Leaf mine. (Fig. 134) Spencer (1969) originally described the mine as an irregular, partly interparenchymal blotch with frass in scattered black grains, frequently with numerous larvae in a single leaf. Spencer & Steyskal (1986) described it as a small, predominantly regular blotch mine, with greenish diffused frass. It is possible that the discrepancy has something to do with Spencer’s including L. subasclepiadis in his original concept of L. asclepiadis, but our own observations indicate that the mine can differ depending on the host species. The mines we observed on Asclepias incarnata were small, irregular, and largely interparenchymal, appearing greenish with associated reddish discoloration, sometimes mottled with whitish on the upper surface. There was little evident frass. The mines on A. exaltata, A. syriaca and A. viridis are entirely on the upper surface, whitish suffused with green to varying degrees, with dark green to black frass in scattered grains or irregular lumps. Mines are at least sometimes initially linear, but this portion is almost always obliterated by the blotch before long. Puparium. Yellow to orange; formed outside the mine. Distribution. USA: IN, *KS, MA, NH, NY; Canada: ON, QC. The record of ID (Lonsdale 2017) is erroneous; IN was intended (Spencer 1969). See comments for other (tentative) distribution data. Comments. The record of this species from Asclepias ovalifolia Decne. in Minnesota (Spencer & Steyskal 1986) is based on empty leaf mines. To this we can add A. subverticillata (A. Gray) Vail (CO) and A. tuberosa L. (KS). We have also seen mines (including photographs posted to www.BugGuide.net) on A. exaltata in IA, on A. syriaca in CT, MD, OH, PA, WI, and NB, and on A. viridis in OK. These records should be confirmed by rearing, given that two other Liriomyza species are known to form blotch mines on Asclepias. Liriomyza peleensis Spencer was reared from A. incarnata at Point Pelee, Ontario, and L. subasclepiadis from A. speciosa Torr. in Yakima Co., Washington (Spencer 1969; Spencer & Steyskal 1986). Spencer (1969) stated that numerous larvae of L. peleensis feed together in a single leaf, “forming a large blotch with frass scattered irregularly in greenish-black grains”, characterizing those of L. asclepiadis as “similar, though smaller”. Neither this description nor the single geographic datapoint for L. peleensis seem sufficient to separate the two with confidence. The mine of L. subasclepiadis is described as irregular and interparenchymal, “frequently partially linear, with frass detectable in 2 lines of strips, but often develop[ing] into [a] secondary blotch; mine appears greenish and may be difficult to detect as a true mine” (Spencer & Steyskal 1986). This largely agrees with our observations of L. asclepiadis on A. incarnata, but the linear portion and strips of frass would be distinctive if present.Published as part of Eiseman, Charles S. & Lonsdale, Owen, 2018, New state and host records for Agromyzidae (Diptera) in the United States, with the description of thirty new species, pp. 1-156 in Zootaxa 4479 (1) on page 46, DOI: 10.11646/zootaxa.4479.1.1, http://zenodo.org/record/145291
Phytomyza spondylii subsp. heracleiphaga Spencer.
No full textPhytomyza spondylii heracleiphaga Spencer (Fig. 207) Material examined. MASSACHUSETTS: Nantucket Co., Nantucket, Abrams Point, 30.v.2012, em. by 24.vi.2012, J. A. Blyth, ex Heracleum maximum (1♂). Host. Apiaceae: Heracleum maximum W. Bartram. Leaf mine. (Fig. 207) A white, upper surface, linear mine, with frass in closely spaced grains along the margins. Spencer (1969) considered the life history information from California presented by Tauber and Tauber (1968) for Phytomyza lanati Spencer actually to refer to this species. Griffiths (1973) doubted this because Tauber and Tauber reported the mine length to be 25–29.5 cm, over twice the length of the 6–10 cm mines from which he reared his Alaskan specimens. However, our Massachusetts specimens were indeed reared from mines over 20 cm long. Puparium. Brown or black, strongly arched, with intersegmental boundaries distinctly impressed; formed outside the mine (Griffiths 1973). Distribution. USA: AK, CA, *MA.
