Title: Part-of-Speech Annotation of Biology Research Abstracts
Abstract: A part-of-speech (POS) tagged corpus was built on research abstracts in biomedical domain with the Penn Treebank scheme. As consistent annotation was difficult without domain-specific knowledge we made use of the existing term annotation of the GENIA corpus. A list of frequent terms annotated in the GENIA corpus was compiled and the POS of each constituent of those terms were determined with assistance from domain specialists. The POS of the terms in the list are pre-assigned, then a tagger assigns POS to remaining words preserving the pre-assigned POS, whose results are corrected by human annotators. We also modified the PTB scheme slightly. An inter-annotator agreement tested on new 50 abstracts was 98.5%. A POS tagger trained with the annotated abstracts was tested against a gold-standard set made from the interannotator agreement. The untrained tagger had the accuracy of 83.0%. Trained with 2000 annotated abstracts the accuracy rose to 98.2%. The 2000 annotated abstracts are publicly available.

Title: Motion synthesis and editing in low-dimensional spaces
Abstract: Human motion is difficult to create and manipulate because of the high dimensionality and spatiotemporal nature of human motion data. Recently, the use of large collections of captured motion data has added increased realism in character animation. In order to make the synthesis and analysis of motion data tractable, we present a low‐dimensional motion space in which high‐dimensional human motion can be effectively visualized, synthesized, edited, parameterized, and interpolated in both spatial and temporal domains. Our system allows users to create and edit the motion of animated characters in several ways: The user can sketch and edit a curve on low‐dimensional motion space, directly manipulate the character's pose in three‐dimensional object space, or specify key poses to create in‐between motions.

Title: Public History and Contested Heritage: Archival Memories of the Bombing of Italy
Abstract: This article presents a case study of a collaborative public history project between participants in two countries, the United Kingdom and Italy. Its subject matter is the bombing war in Europe, 1939-1945, which is remembered and commemorated in very different ways in these two countries: the sensitivities involved thus constitute not only a case of public history conducted at the national level but also one involving contested heritage. An account of the ways in which public history has developed in the UK and Italy is presented. This is followed by an explanation of how the bombing war has been remembered in each country. In the UK, veterans of RAF Bomber Command have long felt a sense of neglect, largely because the deliberate targeting of civilians has not fitted comfortably into the dominant victor narrative. In Italy, recollections of being bombed have remained profoundly dissonant within the received liberation discourse. The International Bomber Command Centre Digital Archive (or Archive) is then described as a case study that employs a public history approach, focusing on various aspects of its inclusive ethos, intended to preserve multiple perspectives. The Italian component of the project is highlighted, problematising the digitisation of contested heritage within the broader context of twentieth-century history. Reflections on the use of digital archiving practices and working in partnership are offered, as well as a brief account of user analytics of the Archive through its first eighteen months online.

Title: A systematic review of literature on contested heritage
Abstract: ABSTRACT Contested heritage has increasingly been studied by scholars over the last two decades in multiple disciplines, however, there is still limited knowledge about what contested heritage is and how it is realized in society. Therefore, the purpose of this paper is to produce a systematic literature review on this topic to provide a holistic understanding of contested heritage, and delineate its current state, trends and gaps. Methodologically, four electronic databases were searched, and 102 journal articles published before 2020 were extracted. A content analysis of each article was then conducted to identify key themes and variables for classification. Findings show that while its research often lacks theoretical underpinnings, contested heritage is marked by its diversity and complexity as it becomes a global issue for both tourism and urbanization. By presenting a holistic understanding of contested heritage, this review offers an extensive investigation of the topic area to help move literature pertaining contested heritage forward.

Title: Case study: using MOOCs for conventional college coursework
Abstract: In Spring 2013 San José State University (SJSU) launched SJSU Plus: three college courses required for most students to graduate, which used massive open online course provider Udacity’s platform, attracting over 15,000 students. Retention and success (pass/fail) and online support were tested using an augmented online learning environment (AOLE) on a subset of 213 students; about one-half matriculated. SJSU faculty created the course content, collaborating with Udacity to develop video instruction, quizzes, and interactive elements. Course log-ins and progression data were combined with surveys and focus groups, with students, faculty, support staff, coordinators, and program leaders as subjects. Logit models used contingency table-tested potential success predictors on all students and five subgroups. Student effort was the strongest success indicator, suggesting criticality of early and consistent student engagement. No statistically significant relationships with student characteristics were found. AOLE support effectiveness was compromised with staff time consumed by the least prepared students.

Title: Raman spectroscopy of the borosilicate mineral ferroaxinite
Abstract: Raman spectroscopy, complemented by infrared spectroscopy has been used to characterise the ferroaxinite minerals of theoretical formula Ca2Fe2+Al2BSi4O15(OH), a ferrous aluminium borosilicate. The Raman spectra are complex but are subdivided into sections based upon the vibrating units. The Raman spectra are interpreted in terms of the addition of borate and silicate spectra. Three characteristic bands of ferroaxinite are observed at 1082, 1056 and 1025 cm-1 and are attributed to BO4 stretching vibrations. Bands at 1003, 991, 980 and 963 cm-1 are assigned to SiO4 stretching vibrations. Bands are found in these positions for each of the ferroaxinites studied. No Raman bands were found above 1100 cm-1 showing that ferroaxinites contain only tetrahedral boron. The hydroxyl stretching region of ferroaxinites is characterised by a single Raman band between 3368 and 3376 cm-1, the position of which is sample dependent. Bands for ferroaxinite at 678, 643, 618, 609, 588, 572, 546 cm-1 may be attributed to the ν4 bending modes and the three bands at 484, 444 and 428 cm-1 may be attributed to the ν2 bending modes of the (SiO4)2-.

Title: DNA barcoding of Northern Nearctic Muscidae (Diptera) reveals high correspondence between morphological and molecular species limits
Abstract: Abstract Background Various methods have been proposed to assign unknown specimens to known species using their DNA barcodes, while others have focused on using genetic divergence thresholds to estimate “species” diversity for a taxon, without a well-developed taxonomy and/or an extensive reference library of DNA barcodes. The major goals of the present work were to: a) conduct the largest species-level barcoding study of the Muscidae to date and characterize the range of genetic divergence values in the northern Nearctic fauna; b) evaluate the correspondence between morphospecies and barcode groupings defined using both clustering-based and threshold-based approaches; and c) use the reference library produced to address taxonomic issues. Results Our data set included 1114 individuals and their COI sequences (951 from Churchill, Manitoba), representing 160 morphologically-determined species from 25 genera, covering 89% of the known fauna of Churchill and 23% of the Nearctic fauna. Following an iterative process through which all specimens belonging to taxa with anomalous divergence values and/or monophyly issues were re-examined, identity was modified for 9 taxa, including the reinstatement of Phaonia luteva (Walker) stat. nov. as a species distinct from Phaonia errans (Meigen). In the post-reassessment data set, no distinct gap was found between maximum pairwise intraspecific distances (range 0.00-3.01%) and minimum interspecific distances (range: 0.77-11.33%). Nevertheless, using a clustering-based approach, all individuals within 98% of species grouped with their conspecifics with high (&gt;95%) bootstrap support; in contrast, a maximum species discrimination rate of 90% was obtained at the optimal threshold of 1.2%. DNA barcoding enabled the determination of females from 5 ambiguous species pairs and confirmed that 16 morphospecies were genetically distinct from named taxa. There were morphological differences among all distinct genetic clusters; thus, no cases of cryptic species were detected. Conclusions Our findings reveal the great utility of building a well-populated, species-level reference barcode database against which to compare unknowns. When such a library is unavailable, it is still possible to obtain a fairly accurate (within ~10%) rapid assessment of species richness based upon a barcode divergence threshold alone, but this approach is most accurate when the threshold is tuned to a particular taxon.

Title: Characterization and comparison of poorly known moth communities through DNA barcoding in two Afrotropical environments in Gabon
Abstract: Biodiversity research in tropical ecosystems-popularized as the most biodiverse habitats on Earth-often neglects invertebrates, yet invertebrates represent the bulk of local species richness. Insect communities in particular remain strongly impeded by both Linnaean and Wallacean shortfalls, and identifying species often remains a formidable challenge inhibiting the use of these organisms as indicators for ecological and conservation studies. Here we use DNA barcoding as an alternative to the traditional taxonomic approach for characterizing and comparing the diversity of moth communities in two different ecosystems in Gabon. Though sampling remains very incomplete, as evidenced by the high proportion (59%) of species represented by singletons, our results reveal an outstanding diversity. With about 3500 specimens sequenced and representing 1385 BINs (Barcode Index Numbers, used as a proxy to species) in 23 families, the diversity of moths in the two sites sampled is higher than the current number of species listed for the entire country, highlighting the huge gap in biodiversity knowledge for this country. Both seasonal and spatial turnovers are strikingly high (18.3% of BINs shared between seasons, and 13.3% between sites) and draw attention to the need to account for these when running regional surveys. Our results also highlight the richness and singularity of savannah environments and emphasize the status of Central African ecosystems as hotspots of biodiversity.

Title: Analyzing Mosquito (Diptera: Culicidae) Diversity in Pakistan by DNA Barcoding
Abstract: Background Although they are important disease vectors mosquito biodiversity in Pakistan is poorly known. Recent epidemics of dengue fever have revealed the need for more detailed understanding of the diversity and distributions of mosquito species in this region. DNA barcoding improves the accuracy of mosquito inventories because morphological differences between many species are subtle, leading to misidentifications. Methodology/Principal Findings Sequence variation in the barcode region of the mitochondrial COI gene was used to identify mosquito species, reveal genetic diversity, and map the distribution of the dengue-vector species in Pakistan. Analysis of 1684 mosquitoes from 491 sites in Punjab and Khyber Pakhtunkhwa during 2010–2013 revealed 32 species with the assemblage dominated by Culex quinquefasciatus (61% of the collection). The genus Aedes (Stegomyia) comprised 15% of the specimens, and was represented by six taxa with the two dengue vector species, Ae. albopictus and Ae. aegypti, dominant and broadly distributed. Anopheles made up another 6% of the catch with An. subpictus dominating. Barcode sequence divergence in conspecific specimens ranged from 0–2.4%, while congeneric species showed from 2.3–17.8% divergence. A global haplotype analysis of disease-vectors showed the presence of multiple haplotypes, although a single haplotype of each dengue-vector species was dominant in most countries. Geographic distribution of Ae. aegypti and Ae. albopictus showed the later species was dominant and found in both rural and urban environments. Conclusions As the first DNA-based analysis of mosquitoes in Pakistan, this study has begun the construction of a barcode reference library for the mosquitoes of this region. Levels of genetic diversity varied among species. Because of its capacity to differentiate species, even those with subtle morphological differences, DNA barcoding aids accurate tracking of vector populations.

Title: Distributions of exotic plants in eastern Asia and North America
Abstract: Although some plant traits have been linked to invasion success, the possible effects of regional factors, such as diversity, habitat suitability, and human activity are not well understood. Each of these mechanisms predicts a different pattern of distribution at the regional scale. Thus, where climate and soils are similar, predictions based on regional hypotheses for invasion success can be tested by comparisons of distributions in the source and receiving regions. Here, we analyse the native and alien geographic ranges of all 1567 plant species that have been introduced between eastern Asia and North America or have been introduced to both regions from elsewhere. The results reveal correlations between the spread of exotics and both the native species richness and transportation networks of recipient regions. This suggests that both species interactions and human-aided dispersal influence exotic distributions, although further work on the relative importance of these processes is needed.

Title: Marketing time predicts naturalization of horticultural plants
Abstract: Horticulture is an important source of naturalized plants, but our knowledge about naturalization frequencies and potential patterns of naturalization in horticultural plants is limited. We analyzed a unique set of data derived from the detailed sales catalogs (1887-1930) of the most important early Florida, USA, plant nursery (Royal Palm Nursery) to detect naturalization patterns of these horticultural plants in the state. Of the 1903 nonnative species sold by the nursery, 15% naturalized. The probability of plants becoming naturalized increases significantly with the number of years the plants were marketed. Plants that became invasive and naturalized were sold for an average of 19.6 and 14.8 years, respectively, compared to 6.8 years for non-naturalized plants, and the naturalization of plants sold for 30 years or more is 70%. Unexpectedly, plants that were sold earlier were less likely to naturalize than those sold later. The nursery's inexperience, which caused them to grow and market many plants unsuited to Florida during their early period, may account for this pattern. Plants with pantropical distributions and those native to both Africa and Asia were more likely to naturalize (42%), than were plants native to other smaller regions, suggesting that plants with large native ranges were more likely to naturalize. Naturalization percentages also differed according to plant life form, with the most naturalization occurring in aquatic herbs (36.8%) and vines (30.8%). Plants belonging to the families Araceae, Apocynaceae, Convolvulaceae, Moraceae, Oleaceae, and Verbenaceae had higher than expected naturalization. Information theoretic model selection indicated that the number of years a plant was sold, alone or together with the first year a plant was sold, was the strongest predictor of naturalization. Because continued importation and marketing of nonnative horticultural plants will lead to additional plant naturalization and invasion, a comprehensive approach to address this problem, including research to identifyand select noninvasive forms and types of horticultural plants is urgently needed.
