    We present the results of the participation of our team Unibo in the shared task sEXism Identification in Social neTworks (EXIST). We target all three tasks: a) binary sexism identification, b) discerning the author’s intention, and c) categorizing instances into fine-grained categories. For all the tasks, both English and Spanish data are to be considered. We compare two approaches to address this multilingual aspect: we employ machine translation to convert the Spanish data into English, allowing us to utilize a specially fine-tuned version of RoBERTa to detect hateful content, and we experiment with a multilingual version of RoBERTa to perform classification while preserving data in their original language. Furthermore, we predict emotions associated with each post and leverage them as additional features by concatenating them with the original text. This augmentation improves the performance of our models in Task 2 and 3. Our official submissions obtain F1=0.77 in Task 1 (13th position out of 69), macro-averaged F1=0.53 in Task 2 (4th position out of 35) and macro-averaged F1=0.59 in Task 3 (4th position out of 32)

    A new micromachined cell lysis device is developed. It is designed for miniature bio-analysis systems where cell lysing is needed to obtain intracellular materials for further analysis such as DNA identification. It consists of muti-electrode pairs to apply electric fields to cells. We adopt the means of using electric field lysing because it can greatly simplify purification steps for preparation of biological samples, when compared to conventional chemical methods. Yeast, Chinese cabbage, radish cells and E. coli are tested with the device. The lysis of yeast, Chinese cabbage, radish cells is observed by a microscope. The experimental observation suggests E. coli are also lysed by the pulsed electric field. The range of electric field for the lysis is on the order of 1 kV/cm to 10 kV/cm. In addition, for practical reasons, we reduce the voltage required for lysing to less than 10 V by making the electrode gap on the order of microns

    Objective: To investigate prostate cancer (Pca) risk in relation to estrogen metabolism, expressed as urinary 2-hydroxyestrone (2-OHE1), 16α-hydroxyestrone (16α-OHE1) and 2-OHE1 to 16α-OHE1 ratio. Methods: We conducted a case-control study within the Western New York Health Cohort Study (WNYHCS) from 1996 to 2001. From January 2003 through September 2004, we completed the re-call and follow-up of 1092 cohort participants. Cases (n = 26) and controls (n = 110) were matched on age, race and recruitment period according to a 1:4 ratio. We used the unconditional logistic regression to compute crude and adjusted odds ratios (OR) and 95% confident interval (CI) of Pca in relation to 2-OHE1, 16αOHE1 and 2-OHE1 to 16α-OHE1 by tertiles of urine concentrations (stored in a biorepository for an average of 4 years). We identified age, race, education and body mass index as covariates. We also conducted a systematic review of the literature which revealed no additional studies, but we pooled the results from this study with those from a previously conducted case-control study using the DerSimonian-Laird random effects method. Results: We observed a non-significant risk reduction in the highest tertile of 2-OHE1 (OR 0.72, 95% CI 0.25-2.10). Conversely, the odds in the highest tertile of 16α-OHE1 showed a non-significant risk increase (OR 1.76 95% CI 0.62-4.98). There was a suggestion of reduced Pca risk for men in the highest tertile of 2-OHE1 to 16α-OHE1 ratio (OR 0.56, 95% CI 0.19-1.68). The pooled estimates confirmed the association between an increased Pca risk and higher urinary levels of 16α-OHE1 (third vs. first tertile: OR 1.82, 95% CI 1.09-3.05) and the protective effect of a higher 2-OHE 1 to 16α-OHE1 ratio (third vs. first tertile: OR 0.53, 95% CI 0.31-0.90). Conclusion: Our study and the pooled results provide evidence for a differential role of the estrogen hydroxylation pathway in Pca development and encourage further study

    Includes bibliographical references.The way in which indigenous people are represented in documentaries has radically changed within the last century. But "If there (still) is one overriding ethical/political / ideological! question to documentary filmmaking it may be, What to do with the people" (Nichols qtd. in Barbash and Taylor, 1997: p. 12). How can people and issues be represented appropriately? How can one make a documentary about somebody or something with a totally different cultural background to one's own without being unethical? The so-called expository documentary was the first prevailing documentary mode and tries to answer these questions with an authoritative voice-over commentary combined with a series of images that aim to be descriptive and informative. The voice-over approaches the spectator directly and offers facts or arguments that are illustrated by the images. It provides abstract information that the image cannot carry or comments on those actions and events that are unfamiliar to the target audience. This is exactly what some filmmakers reacted against - "to explain what the images mean, as if they don't explain themselves, or as if viewers can't be trusted to work the meaning out on their own. Indeed, the voice-over often seems to attribute a reduced meaning to the visuals; that is it denies them a density they might have by themselves" (Barbash and Taylor, 1997: p. 19). It is typical for the expository documentary style that the narrator speaks about or for other people. Some filmmakers see these voice-overs as "colonial, an enemy of the film, the voice of God" or even as "the (non-existent) view from somewhere" (Barbash and Taylor, 1997: p. 47)

    Traditional museums, virtual museums. Dissemination role of ICTs.

    Molti spazi della cultura, che si configurano come musei di sĂ© stessi, presentano al loro interno pochi reperti esposti. È il caso di musei in edifici o aree archeologiche di seconda fascia, dai quali la maggior parte dei reperti Ăš stata spostata in musei di importanza superiore o dove i reperti sono stati rimossi per diverse esigenze organizzative/espositive. In queste situazioni le ICT permettono di sviluppare un efficace sistema di comunicazione e disseminazione, coinvolgendo i visitatori e gli studiosi mediante l’utilizzo di procedure collegate all’Edutainment, all’interactive ed immersive experience, ai serious games e alla gamification. Come caso studio sono presi il Museo delle Mura, come museo in un edificio, e la Villa di Massenzio, come area archeologica, entrambi collocati sulla Via Appia Antica a Roma. Le esigenze della Sovrintendenza sono di valorizzare e divulgare: - la presenza del Museo, collocato in una delle numerose porte romane ancora ben conservate e site nel giro delle Mura Aureliane; - la storia della porta e del breve tratto di mura ad essa connesse; - la storia e l’articolazione delle mura di Roma. Per la Villa di Massenzio l’obiettivo principale Ăš far comprendere la storia e la funzione delle due strutture (il circo ed il Mausoleo di Romolo), oggi visibili e visitabili, garantendo una maggiore comprensione di un’area di circa 4 ettari, in cui i visitatori oggi possono beneficiare solo di alcuni pannelli informativi.Many cultural spaces, which have been transformed into museums contain very few exhibits. In particular, museums in buildings or second-tier archaeological areas, where most of the finds have been moved to museums of major importance or exhibits that have been removed for different organizational/exhibition needs. In these situations, the use of ICT affords the possibility to incorporate effective communication and dissemination systems. As a result, it involves visitors and scholars within the exhibit using procedures related to edutainment, interactive and immersive experiences, serious games and gamification. As a case study are taken the Museum of the Walls, as a museum in building, and the archaeological area of the Maxentius archaeological complex, as an open-air museum, both located on the Ancient Appia road. In the Museum of the Walls Superintendent's requirements are to enhance and disseminate: - the presence of the Museum, located in one of the many well-preserved Roman city gates located in the Aurelian Walls; - the history of the city gate and of the short section of walls connected to it; - the history and articulation of the walls of Rome. In the Maxentius archaeological the main goal is to make understand the history and the function of the two main structures (the circus and a Mausoleum of Romulus), which are visible and open to visitors, ensuring a greater understanding of an area with the size of about 4 hectares, where visitors today can only benefit information from some panels

    REDUPLICATION IN UAB METO

    This article is concerned with reduplication in Uab Meto which divided into three parts. First is general characterization of reduplication in UAb Meto, second are the formal properties of reduplication in Uab Meto, third is the function of reduplication in Uab Meto. Data was elicited from observation and interviewing native speakers. Some data also taken from literatures which written in Uab Meto such as bible and articles in local news papers. Uab Meto has a unique characteristic of reduplicating a word because analyzing morphological process of reduplication is interrelated to other aspects such as clause (syntax) and sound harmony (phonology). Based on data collected, it shown that reduplication can be done to verb, noun, adjective, and adverb. For example, the noun neno ‘day’ has two forms of reduplication, they are neno-neno that is a noun and nen-neno’ is an adverb. The first reduplicated word neno-neno means every day, while the second, nenneno’ means on the day time. Another aspect to see in this article is the function of reduplication. The word muti’ ‘white’ for example, has two form of reduplication, namely muti-muti and mut-muti’. The first reduplicated word muti-muti is an intensification which mean very white/clean but the second mut-muti, there is a transfer of meaning to show similarity which mean ‘looks white’. The two examples above show that reduplication in Uab Meto is a morphological process which is driven by phonological output requirements. Phonological constraints are existed to make the output phonologically harmonic. The result of reduplicated word can be either inflectional or derivational

    OVSNet : Towards One-Pass Real-Time Video Object Segmentation

    Full text link
    Video object segmentation aims at accurately segmenting the target object regions across consecutive frames. It is technically challenging for coping with complicated factors (e.g., shape deformations, occlusion and out of the lens). Recent approaches have largely solved them by using backforth re-identification and bi-directional mask propagation. However, their methods are extremely slow and only support offline inference, which in principle cannot be applied in real time. Motivated by this observation, we propose a efficient detection-based paradigm for video object segmentation. We propose an unified One-Pass Video Segmentation framework (OVS-Net) for modeling spatial-temporal representation in a unified pipeline, which seamlessly integrates object detection, object segmentation, and object re-identification. The proposed framework lends itself to one-pass inference that effectively and efficiently performs video object segmentation. Moreover, we propose a maskguided attention module for modeling the multi-scale object boundary and multi-level feature fusion. Experiments on the challenging DAVIS 2017 demonstrate the effectiveness of the proposed framework with comparable performance to the state-of-the-art, and the great efficiency about 11.5 FPS towards pioneering real-time work to our knowledge, more than 5 times faster than other state-of-the-art methods.Comment: 10 pages, 6 figure

    The social diagnostics of stroke-like symptoms: healers, doctors and prophets in Agincourt Limpopo Province, South Africa

    Get PDF
    This paper focuses on the clinical and social diagnostics of stroke-like symptoms in Limpopo Province, South Africa. The research questions addressed here are: what are the lay understandings of strokelike symptoms and what are the health-seeking behaviours of Tsongan Mozambican refugees and South Africans in this area? The study site is ten villages in the Agincourt sub-district of Limpopo Province which are within the health surveillance area of the Agincourt Health and Population Unit (AHPU) of the University of Witwatersrand. The population are Tsongan who speak Shangaan and comprise self-settled Mozambican refugees who fled to this area during the 1980s across the nearby border and displaced South African citizens. The latter were forcibly displaced from their villages to make way for game reserves or agricultural development and moved to this area when it was the former ‘homeland’ of Gazankulu. The team collected data using rapid ethnographic assessment and household interviews as part of the Southern Africa Stroke Prevention Initiative (SASPI). The main findings are that stroke-like symptoms are considered to be both a physical and social condition, and in consequence plural healing using clinical and social diagnostics is sought to address both these dimensions. People with stroke-like symptoms maintain their physical, mental and social well-being and deal with this affliction and misfortune by visiting doctors, healers, prophets and churches
