SW Sex stars are an informal sub-class of eclipsing nova-like cataclysmic variables. We report 934 new eclipse times measured over the past 17 years for HS 0728+6738 (V482 Cam), SW Sex, DW UMa, HS 0129+2933 (TT Tri), V1315 Aql, PX And, HS 0455+8315, HS 0220+0603, BP Lyn, BH Lyn, LX Ser, UU Aqr, V1776 Cyg, RW Tri, 1RXS J064434.5+334451, AC Cnc, V363 Aur, and BT Mon. When combined with published eclipse times going back in some cases many decades, we show that these binary systems exhibit a range of behaviors, including increasing, decreasing, and possibly oscillating orbital periods. Nevertheless, the duration of these observations is still not long enough to be able to make reliable quantitative statements about their long term behaviors. In addition to these long term trends, we also observed rapid and unusual decreases in the orbital periods of SW Sex and RW Tri during 2017 and 2018, respectively., 17 pages, 6 figures

V1432 Aquilae is the only known eclipsing asynchronous polar. In this respect it is unique and therefore merits our attention. We report the results of a 15-year campaign by the globally distributed Center for Backyard Astrophysics to observe V1432 Aql and investigate its return to synchronism. Originally knocked out of synchrony by a nova explosion before observing records began, the magnetic white dwarf in V1432 Aql is currently rotating slower than the orbital period but is gradually catching up. The fortuitously high inclination of the binary orbit affords us the bonus of eclipses providing a regular clock against which these temporal changes can be assessed. At the present rate, synchronism should be achieved around 2100. The continually changing trajectory of the accretion stream as it follows the magnetic field lines of the rotating white dwarf produces a complex pattern of light emission which we have measured and documented, providing comprehensive observational evidence against which physical models of the system can be tested.

Despite being bright ($V=12$) and nearby ($d=212$ pc) ASAS J071404+7004.3 has only recently been identified as a nova-like cataclysmic variable. We present time-resolved optical spectroscopy obtained at the Isaac Newton Telescope together with $\textit{Swift}$ X-ray and ultraviolet observations. We combined these with $\textit{TESS}$ photometry and find a period of 3.27h and a mass transfer rate of $4-9 \times 10^{-9} M_{sun}/yr$. Historical photometry shows at least one low state establishing the system as a VY Scl star. Our high-cadence spectroscopy also revealed rapidly changing winds emanating from the accretion disc. We have modelled these using the Monte Carlo PYTHON code and shown that all the emission lines could emanate from the wind - which would explain the lack of double-peaked lines in such systems. In passing,we discuss the effect of variability on the position of cataclysmic variables in the $\textit{Gaia}$ Hertzsprung-Russell diagram.

Miras are fascinating stars. A kappa-mechanism in their atmosphere drives pulsations which produce changes in their photometric brightness, apparent spectral type and effective temperature. These pulsations also drive the formation of Balmer emission lines in the spectrum. This behaviour can be observed and investigated with small telescopes. We report on a three-year project combining spectroscopy and photometry to analyse the behaviour of Mira stars SU Cam and RY Cep, and describe how their brightness, colour, spectral type, effective temperature and Balmer emission vary over four pulsation cycles., Comment: 18 pages, 12 figures, 5 tables, accepted for publication in Journal of the AAVSO, references updated for consistency with published version

This thesis is a philosophical engagement with the popular, low, and vernacular theories of History performed and expressed within contemporary Japanese manga (‘comics’) and anime (‘limited animation’), and most importantly, in the global production and consumption of otaku (‘manga and anime fan’) cultural and media ecologies. My project is rooted in a reading of the post-structural theoretical inquiries of Gilles Deleuze in parallel with what media theorist McKenzie Wark calls ‘otaku philosophy’ to examine how both high and low theories articulate anxieties and fascinations with the global theoretical discourses on ‘the ends of History’ and the imminent demise of industrial modernity. The first portion of the thesis is dedicated to a reading of the Japanese counter-cultural manga movement called gekiga (‘dramatic pictures’). In traversing gekiga’s post-war lineages to its revival in the medievalism of otaku artists Miura Kentarō and Yukimura Makoto, the first part postulates on what an anti-modern, anti-historical approach – or what Deleuze and Guattari call a nomadology – might look and feel like as it is mediated in the manga form. The second portion of the thesis examines the way in which Japanese anime mobilises the philosophies of nomadology in its filmic form and transmedial properties. In a critical assessment of the anime works of the otaku-founded media corporation Type-Moon, this section explores the Fate series alongside Deleuzian film and media philosophies to explore the infinite potentialities and recursive limitations of otaku nomadologies as they materialise beyond the screen. By reassessing the rise of otaku culture as a vernacular, global, and cosmopolitan rise in the critique of modernity and History, this thesis hopes to explore how transcultural and transmedial fan philosophies of historicity, memory, and temporality can be recontextualised within current academic debates about the efficacy of post-national historiographic pedagogies explored in the fields of postcolonial studies, comparative studies, global studies, and media studies.

This research examines the challenges of early cost estimation of infrastructure projects within the UK with a focus on why cost overruns are such a persistent issue. The research was carried out by an investigation of existing literature surrounding early estimation in construction, characteristics of UK-based infrastructure projects and cost overruns within infrastructure projects. The data were collected through fourteen semi-structured interviews with estimating professionals who work predominantly on infrastructure projects across the UK. The key findings were that the early estimation process consists of an intricate system of hard and soft information exchange from the many involved parties due to the social and political nature of infrastructure projects; this provides many challenges for the estimator. This led to the idea that an estimate is actually a soft input itself and should not be taken as a hard numerical figure but something which requires human interpretation. Moreover, these challenges are heightened by the number of unknowns and uncertainties that are again part of the very nature of large scale infrastructure projects. This is difficult to address as it is the process of converting soft information into hard information and when soft information is hardened it will inevitably lose some of its information or context. Unfortunately, cost estimates have become to be accepted as hard information even when it is known to be soft information that requires interpretation and sense making.

Multicolour broadband photometry and flux calibrated low resolution spectroscopy between 2014 and 2018 are used to investigate the behaviour of the highly variable Herbig Ae star RR Tauri. As the star experienced a deep Algol-like fade by a factor of over 10 in flux, we found the change in spectral continuum to be grey while H{\alpha} emission flux halved. We also observed the (V-Rc) colour index reddening as the star faded suggesting emission detectable in the Rc-band but beyond our spectral response. We confirm that the circumstellar reddening of RR Tau is consistent with an extinction ratio Rv = 5 and that its spectral type is close to A0. According to its luminosity and temperature RR Tau is located in the H-R diagram among other HAEBE stars contracting onto the Zero Age Main Sequence and has a mass between 4 and 5 MSun., Comment: 12 pages, 8 figures, accepted for publication in the Journal of the British Astronomical Association

V909 Cas is a little-studied example of a \b{eta} Cep pulsating variable located in the OB association Cas OB8 in the Perseus spiral arm of the Milky Way. Photometric observations in 2016-7 provided 30 new times of pulsation extrema and enabled its mean pulsation period to be determined as 0.2067798(1) d. From spectroscopic observations we determined its interstellar extinction and absolute magnitude and luminosity, and located it with other \b{eta} Cep stars in the OB instability region of the H-R diagram., 8 pages, 4 figures, accepted for publication in the Journal of the British Astronomical Association

Acantopsis rungthipae differs from all other species of Acantopsis (Table 4) by combination of no exposed labial barbels, usually distinct small black spot on upper margin of caudal-fin base, 0–1 row of large spots on side of head, no large black spots on dorsal or caudal fins, no black specks beneath midlateral row of black spots (rarely present), usually 9½ branched dorsal rays and 10 pectoral rays, 10–20 dark saddles along dorsal midline, 9– 17 black spots along side of body, 41–43 total vertebrae, body depth 9.0–14.2% SL, body width 5.3–10.3% SL, caudal-peduncle length 11.5–16.1% SL. Comparisons. Acantopsis rungthipae is distinguished from all species of Acantopsis except A. ioa by having no labial barbels. It is distinguished from A. ioa by usually having a distinct small black spot on upper margin of caudal-fin base, 9–17 (vs. 13–21) black spots along side of body, and 41–43 (vs. 46–48) total vertebrae (Fig. 15). It further differs from A. dinema by having large dark spots on side of head, usually lacking conspicuous row of black specks beneath midlateral row of black spots, having usually 9½ (vs. 10½) branched dorsal rays, a distinct small black spot (vs. no spot) on upper margin of caudal-fin base, and usually 4–6 faint, narrow bands (vs. no bands) on caudal fin. It further differs from A. octoactinotos by having usually 9½ (vs. 8½) branched dorsal rays, large dark spots on side of head, usually 10 pectoral rays. It differs from A. spectabilis and A. thiemmedhi in lacking conspicuous black bands on the anal and paired fins and spots or blotches on the caudal fin. It further differs from A. thiemmedhi in lacking a large black blotch on the tip of the anterior rays of the dorsal fin and in having usually 9½ (vs. 10½) branched dorsal rays, and from A. dialuzona by lacking a well developed ocellus on the margin of caudal-fin base and having usually 9½ (vs. usually10½) branched dorsal rays. Description. As in description of genus; Tables 1, 2, 4. Head long (21.6–25.6% SL); snout long (54.7–68.7% HL); no exposed labial barbels; 9½, rarely 10½, branched dorsal rays; 10, rarely 9 or 11, pectoral rays; 29–31 abdominal + 11–12 caudal = 41–43 total vertebrae. Maximum SL = 203.2 mm, TL = 241.3 mm (CAS 238293). Color. Dark spots in 1–2 rows on top of head, usually 1 row anteriorly, 2 posteriorly; dark spots on side of head usually in 1 row. Black line from eye to tip of snout. Ten–20 dark saddles along dorsal midline; 9–17 large dark spots or blotches along lateral line from head to caudal fin; small dark spots on upper side of body; no or few dark spots on lower side of body below midlateral row of dark spots. Dorsal fin with 2–3 faint bands, caudal with 4–5 faint bands; no dark upper and lower margins on caudal fin. Small bold black spot near upper margin of caudal-fin origin. Live individuals yellowish brown dorsally, white below, with large black blotches dorsally and laterally on body; reddish brown streak on lower caudal margin; iridescent yellow on side of head and lower fins. Sexual dimorphism. Males have a longer, ramified first branched pectoral-fin ray. Etymology. This species is named in honor of Rungthip Plongsesthee, who was born on 27 May 1978 and died on 16 July 2014. “Kae” was a dear friend, close colleague, a Ph.D. student of Dr. F. W. H. Beamish at Burapha University, Bangsaen, Thailand, and an extremely enthusiastic ichthyologist who is greatly missed by her many friends. Distribution. Acantopsis rungthipae is the most widespread and common species of Acantopsis in mainland Asia. It is known from the Tapi, Mae Khlong, Chao Phraya, Bang Pakong, and Welu River basins in Thailand, and the Mekong River basin in Thailand, Cambodia, Laos, and Vietnam (Fig. 16).

Acantopsis van Hasselt 1823 Acantopsis Van Hasselt, 1823: 133 (type species: Acantopsis dialuzona Van Hasselt, 1823: 133, by monotypy) Acanthopsis Van Hasselt, 1824: 376, 377 (incorrect spelling of Acantopsis) Prostheacanthus Blyth, 1860: 167 (type species: Prostheacanthus spectabilis Blyth, 1860: 167, by monotypy) Acantopsis and the type species, Acantopsis dialuzona, were described in a letter from J. C. van Hasselt to C. J. Temminck, director of the Leiden Museum. Temminck published the letter in 1823, making van Hasselt���s name available (Kottelat 1987). Alfred (1961b) provided an English translation of the original description: ��� Acantopsis distinguishes itself from them [referring to Acantophthalmus, a synonym of Cobitis] by a very elongate pointed face which in those is blunt and so short that the eyes are situated nearly in a vertical line with the mouth-opening. Owing to this elongation the moveable spines are situated far in front of the eyes and the whole form too divergent (for them) to be combined with each other. I found this animal in the river at Batavia and in my drawing it bears the name Dialuzona Mihi.��� Roberts (1993) provided a previously unpublished but more informative description and a watercolor of A. dialuzona by Valenciennes (fig. 25), a drawing by J. Werner based on RMNH 2707���the type of A. dialuzona (fig. 59), and a vertebral count of 30 abdominal +14 caudal = 44 for the type. The description and illustrations were apparently intended for, but were not included in, the Histoire naturelle des Poissons (Cuvier and Valenciennes 1846). The description included: "Compressed body and head, more pointed snout than in Cobitis. Eyes on top of head, almost touching, preceded by pointed spines. Very small mouth, very short barbels. Dorsal fin in middle of body. Long, pointed pectoral fin. Reddish back, white belly, silvery stripe along side of body, 8���9 darker gray oblong spots. Greenish-gray caudal fin with black dot at upper base. Dorsal-fin rays 11; pectoral-fin rays 10; pelvic-fin rays 7, anal-fin rays 6, caudal-fin rays 15." Bleeker (1860) redescribed A. dialuzona based on additional specimens collected from Batavia [Jakarta]. The description was reproduced in English in van Oijen and Loots (2012:76���77, fig. 4), along with an illustration from the Atlas Ichthyologique (Bleeker 1863 ���1864) of the original drawing of the type left in Java by van Hasselt, as noted by Roberts (1993). Diagnosis. Cobitidae. Distinguished from all other genera by the erectile, bifid ���suborbital��� spine being far forward, approximately midway between the eye and the tip of the long snout (Fig. 5). In other genera of cobitids, the spine is located under or slightly anterior to the eye, never midway between the eye and the tip of the snout. The only other cobitid genus in mainland Southeast Asia with a similar body shape and color pattern is Aperioptus Richardson (Siebert 1991a, Page and Tangjitjaroen 2015), which is distinguished from Acantopsis by having the suborbital spine only slightly anterior to the eye (reaching posteriorly to at least the anterior margin of the eye), 7 branched dorsal-fin rays (8 or more in Acantopsis), and the dorsal-fin origin over, slightly anterior, or slightly posterior to the pelvic-fin origin (vs. far in front of the pelvic-fin origin in Acantopsis). Although morphologically similar, molecular data indicate that Kottelatlimia may be more closely related to one of these two genera than Acantopsis and Aperioptus are to each other (Fig. 4, ��lechtov�� et al. 2008, Havird et al. 2010). Description. Body long and slender, deepest predorsally; straight to slightly arched predorsally, tapering from origin of dorsal fin to narrow caudal peduncle. Venter flat, tapering from origin of pelvic fins, more strongly from origin of anal fin, to caudal peduncle. Dorsal-fin origin far in front of pelvic-fin origin. Head long (22���30% SL); snout long (54���72% HL), pointed, steeply sloped to nape. Suborbital spine bifid, medial point longest (Fig. 5), located near midpoint between eye and tip of snout. Groove containing spine ending below anterior margin of eye; spine ending well before eye. Eye round, subcutaenous, high on rear half of head; interorbital distance less than eye diameter. Window to gas bladder posterior to dorsal limb of cleithrum. Scales absent on head and breast, usually absent along midline of abdomen; rest of body covered with ctenoid scales; scales typically embedded on nape, lower side of body, and often anteriorly on side of body. Caudal fin forked in large individual, emarginated in small individual; lobes subequal. Lateral line complete, extending onto caudal fin for short distance. Branched dorsal rays 8�����11��; branched caudal rays 14, 7 in upper, 7 in lower lobe; branched anal rays 5��; pectoral rays 9���11; pelvic rays 7; 28���35 abdominal plus 10���14 caudal = 39���48 total vertebrae. One pair each of rostral, maxillary, and mandibular barbels; 0���3 pairs of labial barbels. Maximum SL = 212.5 mm, TL = 242.5 mm (A. spectabilis, NIFI 2456). Color. Color patterns vary inter- and intraspecifically. Variation within species, and possibly among species, appears to be related to habitat with darker patterns on individuals living on mixed sand and gravel or in clear water, and lighter patterns on those living on sand only or in turbid water. Intraspecific variation in color can be extreme and is probably in large part accountable for the taxonomic confusion that has surrounded this genus. The most conspicuous aspects of the color pattern of all species are the 1���2 rows of dark-brown to black spots on top of the head, continuing as a row of saddles along the dorsal midline to the origin of the caudal fin, and a row of smaller dark spots or blotches along the midside of the body from the head to the origin of the caudal fin. Spots on top of the head are in one row anterior to the nares and one or two rows posterior to the nares. Dorsal saddles and spots along the side may be faint, and the latter are often obscured by a dusky to dark line along the lateral line. Less well-defined dark spots, blotches, and reticulations may occur on the upper side, and less often on the lower side. Other dark brown to black pigment may include spots on the cheek and opercle, sometimes as 1���2 welldefined rows of large spots with many smaller spots above; large spots or dusky bands on the dorsal, caudal, anal, and paired fins; and a small black spot near the upper margin of the origin of the caudal fin, sometimes developed as an ocellus. The lower side of the head, breast, and belly are white. In life, large individuals have a faint yellow to reddish brown cast dorsally, are translucent white ventrally, and have a green iridescence on the side of the head. Fins are mostly clear but with dusky bands on some or all fins, black spots in the dorsal and caudal fins, and a faint yellowish cast on the paired and anal fins (Inger and Chin 1962, pers. obs.). Some species have a reddish-brown streak along the lower caudal-fin margin near the base. Smaller individuals are more translucent and have less contrasting color patterns. Sexual dimorphism. Males have a longer, ramified first branched pectoral-fin ray as noted by Inger and Chin (1962) and Siebert (1991b, fig. 3), and a distal lobe on the first branched pectoral-fin ray in at least one species (A. dinema, Fig. 5). In some, perhaps all species males reach a smaller adult size. In the largest series of specimens examined, (UF 188116; A. dinema) males (N = 15) averaged 88.1 mm SL, and females (N = 45) averaged 99.5 mm SL. In at least some species, the medial point of the suborbital spine is longer and more curved in males (Siebert 1991b). Interspecific and seasonal variation in sexually dimorphic characteristics, perhaps including color, remains mostly unknown in Acantopsis., Published as part of Boyd, David A., Nithirojpakdee, Patchara, Deein, Gridsada, Vidthayanon, Chavalit, Grudpan, Chaiwut, Tangjitjaroen, Weerapongse, Pfeiffer, John M., Randall, Zachary S., Srisombat, Tippamas & Page, Lawrence M., 2017, Revision of the horseface loaches (Cobitidae, Acantopsis), with descriptions of three new species from Southeast Asia, pp. 151-192 in Zootaxa 4341 (2) on pages 161-163, DOI: 10.11646/zootaxa.4341.2.1, http://zenodo.org/record/1039411, {"references":["Van Hasselt, J.

Seven���9 dark saddles along dorsal midline; 6���10 large dark spots or blotches along lateral line from head to caudal fin; dark spots and blotches on upper side of body, none on lower side. Large black blotch near tip of anterior rays of dorsal fin, separated from black band near margin of fin; large individuals with second band in middle of fin with black spot anteriorly. Large black blotch on each lobe of caudal fin, sometimes with dark band connecting blotches; often smaller black spots or bands in middle of caudal fin. Faint bands on other fins. No small bold black spot or ocellus near upper margin of caudal-fin origin. Live individuals yellowish brown dorsally, white below, with large black blotches dorsally and laterally on body; dorsal and caudal fins with black and white bands and spots, iridescent yellow on side of head and lower fins. Distribution. Acantopsis thiemmedhi is widespread, but seemingly uncommon, in the Chao Phraya River basin, Thailand (Fig. 13). Most of the specimens examined are from the Wang River drainage. Remarks. The holotype of Acantopsis thiemmedhi, KUMF 3131, was examined and found to differ in fin ray counts from those recorded by Sontirat (1999). It has 9 branched dorsal rays, 11 pectoral rays, and 7 pelvic rays.

It also is known from the Nam Lik, a large tributary of the Mekong in Laos, and the Srepok River, a large tributary of the Mekong in Cambodia.

Several values for the magnitudes and spectral types of the components of the binary Mira X Ophiuchi have been published in the literature over the last century. Analysis of new photometry and spectroscopy of the star between 2016 May and 2016 December indicates that the V magnitude of the constant star is 9.0 and its spectral type K1III. The spectral type of the Mira changed from M6III at maximum to M7III as it faded and passed through minimum. The V magnitude of the Mira varied between 6.47 at maximum and 9.83 at minimum, a range of 3.36 magnitudes., Comment: Accepted for publication in the Journal of the British Astronomical Association, 10 pages, 8 figures

This chapter explores how procuring agencies can learn from their own projects by studying the decision-making process in previous projects. It contributes to the W118 research and development agenda by deepening the understanding of mechanisms behind the regulation of supply with the construction industry. The chapter focuses on elements influencing project success and reasons why certain client behaviour in procurement situations may be more effective than others. It also contributes to the understanding of governance mechanisms of client organisations. The chapter describes how the learning experience of the Dutch Highway Agency led to adaptation of project governance structures in the consecutive infrastructure projects. It also explores how learning experiences from procurement processes influence project governance within one client organisation. A formal evaluation of each project on the procurement and project governance aspects of projects can contribute significantly to the learning capacity of a client organisation.

The symbiotic star AG Dra experienced a double-peaked outburst of 0.6 magnitudes in April and May 2016. Photometry and spectroscopy through the outburst showed the B-V colour index varying linearly with the V magnitude and enabled the temperature variation of the hot star to be calculated from the changing flux in the H beta and He II 4686A emission lines., 5 pages, 4 figures

The Building Alliance and the Digital Construction Research Centre at Birmingham City University recently worked with 50 key stakeholders, to identify the opportunities that digital construction can offer to improve the process of building and living in new homes. This report details the findings and concludes that digital construction offers the housing industry enormous opportunities to improve their financial return and customer satisfaction. This can be achieved through efficient design and construction processes, an enhanced customer experience and pro-active management of whole house performance and maintenance.

There is a growing awareness that the problematic nature of collaboration in construction design projects is further complicated by the use of interoperable information technologies (IT) in Building Information Modelling (BIM) enabled projects. Consequently, there is a need to better understand the ways interoperable IT get involved in inter-disciplinary relations and affect mutual engagement of different design members. Findings from the study of a BIM enabled design project are analysed using the concept of interdependencies in the interactions between practitioners and their organisations. The paper draws a distinction between “model interdependencies” and “design interdependencies” concerned with the IT and the design task respectively. This distinction helps to deal with the complex nature of practice by expressing the different needs people have in their task interactions using technology in organisations. It is concluded that the conflicts between model and design interdependencies cause segregation into separate model development and design development at the organisational level. Project organisations should be aware of this and take necessary social and technological precautions to achieve better design collaboration.

We present the fourteen year-long light curve of the SW Sextantis nova-like variable, HS 0455+8315, from 2000 November to 2015 February which reveals two deep faint states at magnitude 19 - 20, each of which lasted about 500 and 540 days. Outside these faint states, the star spent most of the time in a normal state at a magnitude of about 15.3. The second faint state was the better observed of the two and was found to have a linear decline of 0.009 mag/day, which was soon followed by a more rapid brightening at -0.020 mag/day. Time series photometry during both the normal state and near minimum light at about magnitude 18 showed that the eclipses had very similar profiles and that outside the eclipse there were irregular modulations typical of the flickering inherent to accreting CVs. Our photometry leading up to the minimum shows that accretion was still ongoing during this time., 13 pages, 5 figures.

The main goals of this research were to reconstruct the infrageneric phylogeny of the genus Primula based on both nuclear and chloroplast DNA sequences, and to use the resulting phylogenies to elucidate the evolution of breeding systems, morphological characters, chromosome number, and biogeographic distribution in the genus. In this paper, the results of a pilot study based on the nuclear ribosomal Internal Transcribed Spacer (ITS) region are described. ITS sequences from 21 taxa produced a number of variable characters sufficient to resolve relationships among sections. The resulting phylogeny confirmed the monophyly of sections Auricula and Aleuritia. Sections Armerina, Proliferae, Crystallophlomis, Parryi, and Auricula, with a base chromosome number of x = 11, and sect. Aleuritia, with a base chromosome number of x = 9, formed two well supported clades. The ITS topology also suggested that leaves with revolute vernation, previously believed to be a derived state, might represent the ancestral condition in Primula, with later reversals to the involute condition. Finally, this initial ITS tree provides preliminary support to the proposed role of the widespread, diploid and heterostylous P. mistassinica as having given origin to the polyploid, homostylous P. incana and P. laurentiana.

The semiregular variable Z UMa experienced a particularly deep minimum at the end of March 2014 followed by a three month rise to maximum. The rise and subsequent decline were followed with low resolution (R~1000) spectroscopy, possibly for the first time. The spectral type of Z UMa varied between M7III at minimum and M4III at maximum while the bright hydrogen emission lines reported by observers during the last century now appear relatively weak and transitory., Comment: 5 pages, 3 figures

V1432 Aquilae is the only known eclipsing asynchronous polar. In this respect it is unique and therefore merits our attention. We report the results of a 15-year campaign by the globally distributed Center for Backyard Astrophysics to observe V1432 Aql and investigate its return to synchronism. Originally knocked out of synchrony by a nova explosion before observing records began, the magnetic white dwarf in V1432 Aql is currently rotating slower than the orbital period but is gradually catching up. The fortuitously high inclination of the binary orbit affords us the bonus of eclipses providing a regular clock against which these temporal changes can be assessed. At the present rate, synchronism should be achieved around 2100. The continually changing trajectory of the accretion stream as it follows the magnetic field lines of the rotating white dwarf produces a complex pattern of light emission which we have measured and documented, providing comprehensive observational evidence against which physical models of the system can be tested., 14 pages, 16 figures, presented at the Society for Astronomical Sciences 33rd Annual Symposium on Telescope Science, June 2014, acknowledgements added

Construction industry clients and regulators repeatedly call for the industry to reduce the cost of construction projects. Real cost reduction requires improvement in site operations. However, much of the industry expends effort in merely buying more cheaply. If a main contractor is looking to a subcontractor to undertake improvement for the sake of the supply chain, they need to be able to assess this and motivate it by a payment process that passes on the reward. Research is described that explores whether current costing methods could account for improvements in work processes. It considers cost as information and explores how contractors derive and use it. A case study of a major main contractor and two subcontractors is described that involved semi-structured interviews and document reviews. The results show that firms recognised that the costing practices they were using had unintended negative strategic and operational consequences. The research concludes that information about cost, that would be useful in a programme that seeks to improve site operations, is hidden in layers of commercial assumptions and lost when it does not cross the boundaries between organisations. A key finding is that automation of current cost management methods in BIM will not improve construction site operations. It will only produce more convoluted details that do not reflect what people actually do.

Z Cam stars are a small subset of dwarf novae that exhibit standstills in their light curves. Most modern literature and catalogs of cataclysmic variables quote the number of known Z Cams to be on the order of 30 or so systems. After a four-year observing campaign and an exhaustive examination of the data in the AAVSO International Database we have trimmed that number by a third. One of the reasons for the misclassification of some systems is the fact that the definition of what a Z Cam is has changed over the last 85 years to what it is today. This has caused many stars formerly assumed to be Z Cams or rumored to be Z Cams to be eliminated from the final list. In this paper we present the results of our investigation into 65 stars listed at one time or another in the literature as Z Cams or possible Z Cams., 22 pages, 26 figures, 3 tables, accepted for publication in the Journal of the AAVSO

A series of spectra of the RV Tauri star R Scuti taken as it rose from a deep minimum to a bright maximum during 2013 October and November reveals major changes taking place in the photosphere and outer atmosphere of the star. This may be the first such series of spectra and demonstrates the capability of amateur spectroscopy for studying these complex stars., Comment: 3 pages, 5 figures

We report the results of a twenty-eight-month photometric campaign studying V1432 Aql, the only known eclipsing, asynchronous polar. Our data show that both the residual eclipse flux and eclipse O-C timings vary strongly as a function of the spin-orbit beat period. Relying upon a new model of the system, we show that cyclical changes in the location of the threading region along the ballistic trajectory of the accretion stream could produce both effects. This model predicts that the threading radius is variable, in contrast to previous studies which have assumed a constant threading radius. Additionally, we identify a very strong photometric maximum which is only visible for half of the beat cycle. The exact cause of this maximum is unclear, but we consider the possibility that it is the optical counterpart of the third accreting polecap proposed by Rana et al. (2005). Finally, the rate of change of the white dwarf's spin period is consistent with it being proportional to the difference between the spin and orbital periods, implying that the spin period is approaching the orbital period asymptotically., Comment: 28 pages, 9 figures; label on Y-axis in Fig. 2 has been corrected (was incorrect in 1408.4207v1)

We report photometric and spectroscopic observations of the 2014 eclipse of EE Cep. This proved to be one of the shallower eclipses on record rather than one of the deepest as predicted. The general shape of the eclipse light curve was similar to that of the 2003 eclipse. The spectral type before and after eclipse was consistent with B5III and became slightly later at mid-eclipse. Total flux in the H{\alpha} emission line remained relatively constant through the eclipse., Comment: 7 pages, 4 figures, submitted to the Journal of the British Astronomical Association

We present the 13-year light curve of HW Boo between 2001 May and 2014 May. We identified 12 outbursts, which typically lasted 2 to 5 days, with an amplitude of 2.7 to 3.6 magnitudes. Time resolved photometry during two outbursts revealed small hump-like structures which increased in size as the outburst progressed, reaching a peak-to-peak amplitude of ~0.8 mag. They occurred on timescales of 15 min to an hour, but did not exhibit a stable period. Similar irregular hump-like variations of 0.1 to 0.8 magnitudes, at intervals of 7 to 30 minutes, were also detected during quiescence. We discuss whether HW Boo might be a dwarf nova of the SU UMa family or an Intermediate Polar, but require further observations to support classification., Comment: 14 pages, 5 Figures.

Sustainability in construction has attracted considerable attention from scholars as well as from regulatory bodies. However, early design stage sustainability analysis remains problematic because of the conflicting factors affecting sustainability, the limited and fragmented project data in hand at early design stage and deficiencies of existing sustainability analysis software for quick evaluation of conceptual design alternatives. BIM's building information management and integration capabilities present opportunities to support early design sustainability analysis. In this paper, early findings of an on-going\ud BIM based early design sustainability analysis application development project are presented. Through literature review and in-depth interviews conducted with a sustainability professional, a categorization of the information needed for quick evaluation of different conceptual design alternatives from a sustainability point of view is developed. The categorization developed and presented in this paper aims to guide further stages of the project of the development of the application and also to support the writing of a BIM Execution Plan for projects where holistic early design sustainability analysis is intended.

Results are presented of a five-year project to study the orbital periods of eighteen deeply eclipsing novalike cataclysmic variables, collectively known as SW Sextantis stars, by combining new measurements of eclipse times with published measurements stretching back in some cases over fifty years. While the behaviour of many of these binary systems is consistent with a constant orbital period, it is evident that in several cases this is not true. Although the time span of these observations is relatively short, evidence is emerging that the orbital periods of some of these stars show cyclical variation with periods in the range 10-40 years. The two stars with the longest orbital periods, V363 Aur and BT Mon, also show secular period reduction with rates of -6.6 \times 10^{-8} days/year and -3.3 \times 10^{-8} days/year. New ephemerides are provided for all eighteen stars to facilitate observation of future eclipses., 26 pages, 7 figures

Safe male circumcision (SMC) decreases risk of HIV transmission (Weiss et al., 2008a). Mathematical modeling indicates that in order to yield significant declines in HIV prevalence in sub-Saharan Africa, wide adoption of SMC is necessary (Nagelkerke, Moses, de Vlas & Bailey, 2007). Therefore, research about trends and determinants of uptake of SMC among historically non-circumcising groups in this region is essential. This cross-sectional study explored the relationship between educational attainment and young men’s willingness to undergo SMC in rural areas of central Uganda. Sub-counties were randomly selected in three districts (Mukono, Wakiso and Kiboga) and a standardized survey was administered to 297 male youths (aged 18-24). Focus group discussions were also held in each district to gauge attitudes towards SMC. Survey data was analyzed using stepwise logistic regression in STATA 11.0. Respondents with higher educational attainment had lower willingness to undergo SMC after adjusting for selected demographic variables [OR=0.20; p=0.0010]. In parametric path analysis, there was marginal evidence, p= 0.0597 (Goodman test), that awareness of SMC benefits is a partial mediator in the causal pathway between education and willingness. These findings indicate that willingness to undergo SMC in central Uganda decreases with increased educational attainment. This disparity could decrease the impact of SMC on HIV prevalence in Uganda., The Journal of Global Health at Columbia University, Vol. 2 No. 1 (2012): Spring 2012

We report unfiltered photometry of BG Arietis (= SDSS J015151.87+140047.2) in 2009 and 2010 which shows the presence of superhumps with peak-to-peak amplitude of up to 0.36 magnitudes showing this to be an SU UMa type dwarf nova. The outburst amplitude was 5.1 magnitudes above a mean quiescence magnitude of 19.9. The 2010 event lasted at least 20 days during which we observed a precursor outburst which was immediately followed by a superoutburst. Modulations were observed during the rise to superoutburst with a period approximately half Porb. The mean superhump period during the plateau phase was Psh = 0.0849(6) d, representing a superhump period excess epsilon = 0.030(7). We also observed small eclipses of depth 0.06 to 0.13 magnitude and FWHM duration of ~12 mins ({\Delta}{\Phi}1/2 = 0.10), which we interpret as grazing eclipses of the accretion disc. The 2009 superoutburst was less well observed, especially in the early stages, so we cannot tell whether there was a precursor outburst. The mean superhump period during the plateau was Psh = 0.0851(4) d, but towards the end of the plateau it suddenly decreased to Psh = 0.0845(11) d. Small eclipses were also observed., Comment: Accepted for publication in the Journal of the British Astronomical Association. 25 pages, 8 figs
