NEW shared & interconnected ASL resources: SignStream® 3 Software; DAI 2 for web access to linguistically annotated video corpora; and a sign bank

2017 marked the release of a new version of SignStream® software, designed to facilitate linguistic analysis of ASL video. SignStream® provides an intuitive interface for labeling and time-aligning manual and non-manual components of the signing. Version 3 has many new features. For example, it enables representation of morpho-phonological information, including display of handshapes. An expanding ASL video corpus, annotated through use of SignStream®, is shared publicly on the Web. This corpus (video plus annotations) is Web-accessible—browsable, searchable, and downloadable—thanks to a new, improved version of our Data Access Interface: DAI 2. DAI 2 also offers Web access to a brand new Sign Bank, containing about 10,000 examples of about 3,000 distinct signs, as produced by up to 9 different ASL signers. This Sign Bank is also directly accessible from within SignStream®, thereby boosting the efficiency and consistency of annotation; new items can also be added to the Sign Bank. Soon to be integrated into SignStream® 3 and DAI 2 are visualizations of computer-generated analyses of the video: graphical display of eyebrow height, eye aperture, an

Update on linguistically annotated ASL video data available through the American Sign Language Linguistic Research Project (ASLLRP)

The American Sign Language Linguistic Research Project (ASLLRP) provides Internet access to high-quality ASL video data, generally including front and side views and a close-up of the face. The manual and non-manual components of the signing have been linguistically annotated using SignStream®. The recently expanded video corpora can be browsed and searched through the Data Access Interface (DAI 2) we have designed; it is possible to carry out complex searches. The data from our corpora can also be downloaded; annotations are available in an XML export format. We have also developed the ASLLRP Sign Bank, which contains almost 6,000 sign entries with distinct English-based glosses, with a total of 41,830 examples (in addition to about 300 gestures, over 1,000 fingerspelled signs, and 475 classifier examples). The Sign Bank is likewise accessible and searchable on the Internet; it can also be accessed from within SignStream® to make annotations more accurate and efficient. Here we describe the available resources. These data have been used for many types of research into computerbased sign language recognition from video.IIS-1763486 - National Science Foundation; 000000000000000000000000000000000000000000000000000000001676 - Rutgers, The State University of New JerseyPublished versio

Improving the competitiveness and marketability of locally-produced rice in Ghana

Irrigated rice has been grown over a number of decades in Ghana on state-sponsored government irrigation projects. Over the years these projects have received extensive state support, as the government has attempted, through various initiatives, to achieve food self-sufficiency. The emphasis on promoting domestic rice production was enhanced by the growing importance of rice in the diet of the urban population, combined with technical assistance provided by donors, such as the Chinese. In addition, the promotion of state-sponsored, input-intensive agriculture reflected the Ghanaian government's past adherence to socialist development models

Strategies to Reduce the Impact of Resource Consumption in the Ghanaian Construction Industry

With a growing priority on resolving environmental issues and managing resources more effectively in line with Sustainable Development Goal 12, this research aims to assess solutions to minimize resource consumption in the Ghanaian construction sector. In the Ghanaian cities of Accra and Kumasi, questionnaires were utilized to solicit responses from construction stakeholders. Mean score ranking was used to rank these techniques. A reliability analysis using Cronbach's alpha coefficient found a high level of internal consistency. A high level of agreement was found after testing using Kendall's concordance. A one-sample t-test was also employed to examine the relative importance of the variables. Properties should be built to be disassembled; sections of existing building structures should be reused; prefabricated components should be utilized for on-site assembly; demolition components should be re-used or recycled, and existing buildings should be renovated to prevent destruction. This research is valuable because it adds to a checklist of measures for minimizing the effect of resource consumption in the Ghanaian construction sector, as well as to the achievement of the SDG goal. Project managers, architects, engineers, subcontractors, and other key stakeholders are encouraged to use innovative approaches to decrease resource consumption

Determination of the Levels of Some Heavy Metals in Cocoa Beans from Selected Cocoa- Growing Areas in Western and Ashanti Regions of Ghana

In this study, six heavy metals in cocoa beans from some cocoa-growing towns in the Western and Ashanti regions were determined after acid digestion using analytical grades of concentrated nitric acid and concentrated hydrochloric acid. Cadmium, lead, copper, Manganese, Iron and zinc in the samples were determined by atomic absorption spectroscopy. The metal levels in cocoa beans from the Western region, expressed in mg/ kg varied from 0.045 to 0.066 with mean value of 0.054 for cadmium, from 0.013 to 0.03 with mean value of 0.02 for lead, from 46.47 to 55.17 with mean value of 51.98 for copper, from 48.36 to 64.65 with mean value of 55.18 for manganese, from 43.80 to 53.11 with the mean value of 47.51 iron, from 43.04 to 52.06 with the mean value of 48.29 for zinc. That of Ashanti region ranged from 0.05 to 0.065 with the mean value of 0.056 for cadmium, from 0.014 to 0.02 with the mean value of 0.017 for lead, from 47.43 to 54.17nwith the mean values of 49.10 for copper, from 47.15 to 57.34 with the mean value of 54.62 for manganese, from 50.23 to 63.87 with the mean value of 54.63 for iron and from 53.02 to 58.71 with the mean value of 56.49 for zinc. For overall conclusion, heavy metals were present in all samples but the levels of zinc, copper, iron and manganese which are considered as essential elements were high as compared to the toxic cadmium and lead. Levels according to codex set up by FAO/WHO therefore makes cocoa beans from the Western and Ashanti regions of Ghana analyzed in this study  safe for consumption

Resources for computer-based sign recognition from video, and the criticality of consistency of gloss labeling across multiple large ASL video corpora

The WLASL purports to be “the largest video dataset for Word-Level American Sign Language (ASL) recognition.” It brings together various publicly shared video collections that could be quite valuable for sign recognition research, and it has been used extensively for such research. However, a critical problem with the accompanying annotations has heretofore not been recognized by the authors, nor by those who have exploited these data: There is no 1-1 correspondence between sign productions and gloss labels. Here we describe a large, linguistically annotated, video corpus of citation-form ASL signs shared by the ASLLRP—with 23,452 sign tokens and an online Sign Bank—in which such correspondences are enforced. We furthermore provide annotations for 19,672 of the WLASL video examples consistent with ASLLRP glossing conventions. For those wishing to use WLASL videos, this provides a set of annotations making it possible: (1) to use those data reliably for computational research; and/or (2) to combine the WLASL and ASLLRP datasets, creating a combined resource that is larger and richer than either of those datasets individually, with consistent gloss labeling for all signs. We also offer a summary of our own sign recognition research to date that exploits these data resources.Published versio

A randomized, open-label study of the tolerability and efficacy of one or three daily doses of ivermectin plus diethylcarbamazine and albendazole (IDA) versus one dose of ivermectin plus albendazole (IA) for treatment of onchocerciasis

BACKGROUND: Onchocerciasis ( river blindness ) has been targeted for elimination. New treatments that kill or permanently sterilize female worms could accelerate this process. Prior studies have shown that triple drug treatment with ivermectin plus diethylcarbamazine and albendazole (IDA) leads to prolonged clearance of microfilaremia in persons with lymphatic filariasis. We now report results from a randomized clinical trial that compared the tolerability and efficacy of IDA vs. a comparator treatment (ivermectin plus albendazole, IA) in persons with onchocerciasis. METHODS AND FINDINGS: The study was performed in the Volta region of Ghana. Persons with microfiladermia and palpable subcutaneous nodules were pre-treated with two oral doses of ivermectin (150 μg/kg) separated by at least 6 months prior to treatment with either a single oral dose of ivermectin 150 μg/kg plus albendazole 400 mg (IA), a single oral dose of IDA (IDA1, IA plus diethylcarbamazine (DEC. 6 mg/kg) or three consecutive daily doses of IDA (IDA3). These treatments were tolerated equally well. While adverse events were common (approximately 30% overall), no severe or serious treatment-emergent adverse events were observed. Skin microfilariae were absent or present with very low densities after all three treatments through 18 months, at which time nodules were excised for histological assessment. Nodule histology was evaluated by two independent assessors who were masked regarding participant infection status or treatment assignment. Significantly lower percentages of female worms were alive and fertile in nodules recovered from study participants after IDA1 (40/261, 15.3%) and IDA3 (34/281, 12.1%) than after IA (41/180, 22.8%). This corresponds to a 40% reduction in the percentage of female worms that were alive and fertile after IDA treatments relative to results observed after the IA comparator treatment (P = 0.004). Percentages of female worms that were alive (a secondary outcome of the study) were also lower after IDA treatments (301/574, 52.4%) than after IA (127/198, 64.1%) (P = 0.004). Importantly, some comparisons (including the reduced % of fertile female worms after IDA1 vs IA treatment, which was the primary endpoint for the study) were not statistically significant when results were adjusted for intraclass correlation of worm fertility and viability for worms recovered from individual study participants. CONCLUSIONS: Results from this pilot study suggest that IDA was well tolerated after ivermectin pretreatment. They also suggest that IDA was more effective than the comparator treatment IA for killing or sterilizing female O. volvulus worms. No other short-course oral treatment for onchocerciasis has been demonstrated to have macrofilaricidal activity. However, this first study was too small to provide conclusive results. Therefore, additional studies will be needed to confirm these promising findings. TRIAL REGISTRATION: The study is registered at Cinicaltrials.gov under the number NCT04188301
