Making visible the invisible through the analysis of acknowledgements in the humanities
Purpose: Science is subject to a normative structure that includes how the
contributions and interactions between scientists are rewarded. Authorship and
citations have been the key elements within the reward system of science,
whereas acknowledgements, despite being a well-established element in scholarly
communication, have not received the same attention. This paper aims to put
forward the bearing of acknowledgements in the humanities to bring to the
foreground contributions and interactions that, otherwise, would remain
invisible through traditional indicators of research performance.
Design/methodology/approach: The study provides a comprehensive framework to
understanding acknowledgements as part of the reward system with a special
focus on its value in the humanities as a reflection of intellectual
indebtedness. The distinctive features of research in the humanities are
outlined and the role of acknowledgements as a source of contributorship
information is reviewed to support these assumptions.
Findings: Peer interactive communication is the prevailing support thanked in
the acknowledgements of humanities, so the notion of acknowledgements as
super-citations can make special sense in this area. Since single-authored
papers still predominate as publishing pattern in this domain, the study of
acknowledgements might help to understand social interactions and intellectual
influences that lie behind a piece of research and are not visible through
authorship.
Originality/value: Previous works have proposed and explored the prevailing
acknowledgement types by domain. This paper focuses on the humanities to show
the role of acknowledgements within the reward system and highlight publication
patterns and inherent research features which make acknowledgements
particularly interesting in the area as reflection of the socio-cognitive
structure of research.Comment: 14 page
Preparing M1/M2 students for the surgical wards – An on call shadowing program
Traditionally, medical students gain initial exposure to surgical fields during their third year of Medical School. Many pre-clinical medical students have little exposure to surgeons, and therefore may enter the third year clerkship with pre-conceived notions of surgeons, or surgery in general. By this time many students have already established preset attitudes and pre-conceived notions about surgeons and surgery. Our goal is to construct a program through which interest in surgery can be positively influenced in the pre-clinical years, and possibly attract talented students to the field. This program would also help better prepare students for a third year surgery clerkship. A voluntary Trauma and Acute Care surgery shadowing program was initiated by a group of medical students with the support of the Department of Surgery and the School of Medicine at the Virginia Commonwealth University Medical Center, an urban, academic teaching hospital and level I trauma center. All medical students are invited to participate in one of three 12-hour shifts available each weekend. In the two years of the program 167 pre-clinical students, 141(85.5%) of which were in their first year of medical school, participated in taking trauma call. On average students witnessed 6.39 trauma alerts and 1.34 operative cases per shift (table 2). On average students indicated they benefited most from working with third and fourth year medical students. Based on the follow up survey there was a significant increase in interest in surgery following the shift. 88% of students noted the experience was a good learning experience and provided insight into 3rd year clerkship expectation. Lastly, 69% of students commented on how impressed they were with some aspect of trauma surgery, such as the camaraderie, medical management of patients, and wide breadth of knowledge. Based on the popularity of the program, we are continuing this program indefinitely, and it is being modeled by other departments within the School of Medicine

Women's Empowerment in Nike Advertisements: A Multimodal Analysis
Aside from promoting certain products, advertisements are also utilized to promote social issues. One of the social issues promoted is women’s empowerment. This type of advertisement, which promotes women’s empowerment, is named as femvertising. In promoting this issue in a video advertisement, the combination of verbal modes and non-verbal modes are used to convey the message. The study examines two recent advertisements by Nike to reveal the message of women’s empowerment. The study used multimodal discourse analysis to examine the advertisements which were in the form of moving images, as it tried to uncover the modes present in both advertisements, and how those modes construct the discourse of women’s empowerment delivered by the narrators of both advertisements. In exploring the visual modes, Kress and van Leeuwen’s framework of visual grammar, which included representational meaning, interactive meaning, and compositional meaning, was used. The verbal analysis was explored using Hallidayan three layers of metafunction, which included the analysis of transitivity, mood structure, and theme-rheme. The study revealed that the interplay of all the modes that were analyzed put women to be doing sporting activities in sports-related settings, to possess more power than the viewers, as the most salient elements, and to be narrated with encouraging utterances in both advertisements
Development of a Bio-inspired GNS methodology in the dark environment
The current research explores the connection between gazing and locomotion of acoustic guided animals and the application of this in autonomous vehicles guidance and navigation strategies. Research groups worldwide are currently investigating different technologies and autonomous guidance algorithm-based strategies. The use of nature-inspired innovations ensures both the efficiency and the robustness of guidance strategies. The current research looks to fill the lack of research of those methodologies using bio-inspired techniques for acoustic guided animals as only visual-based methodologies have been implemented for a variety of tasks. Also, to connect the results from bat¿s flight experiments of Moss et al. with the Tau Theory of David Lee. The connection between the Tau Theory and flight dynamics and manoeuvring is another interesting topic not only for autonomous navigation but also for handling qualities and safety improvement. After carrying out a data analysis of Bat¿s flight experiments through the cluttering of the environment and connecting the flight behaviour with the extensive research done upon environmental cues perception guiding locomotion action for visual and acoustic cues. This concept is in an early phase of development and therefore, the aim is to set the baseline for further research on the topic. Results showed that bats perform a controlled braking manoeuvre when closing gaps, which is coined the term ¿Energised Approach¿. However, biased errors were found in some cases hence the results were negatively impacted, causing the results to be inaccurate in certain phases of the analysis. Despite the error found post-analysis, the results found in this research can still be considered insightful however artificial intelligence algorithms should be incorporated in future studies in order to achieve a more accurate result and finding.Outgoin
Infecção por riquétsias em carrapatos de aves silvestres em duas ecorregiões da Argentina
Several tick-borne Rickettsia species are recognized human pathogens in Argentina. Here we evaluated rickettsial infection in ticks collected on passerine birds during 2011-2012 in two eco-regions of Argentina. The ticks were processed by molecular analysis through polymerase chain reaction (PCR) detection and DNA sequencing of fragments of two rickettsial genes, gltA and ompA. A total of 594 tick specimens (532 larvae and 62 nymphs), representing at least 4 species (Amblyomma tigrinum, Ixodes pararicinus, Haemaphysalis juxtakochi, Haemaphysalis leporispalustris), were evaluated. At least one A. tigrinum larva, collected on Coryphospingus cucullatus in Chaco Seco, was infected with Rickettsia parkeri, whereas at least 12 larvae and 1 nymph of I. pararicinus, collected from Troglodytes aedon, Turdus amaurochalinus, Turdus rufiventris, C. cucullatus and Zonotrichia capensis, were infected with an undescribed Rickettsia agent, genetically related to several rickettsial endosymbionts of ticks of the Ixodes ricinus complex. R. parkeri is a recognized human pathogen in several American countries including Argentina, where a recent study incriminated A. tigrinum as the potential vector of R. parkeri to humans. Birds could play an important role in dispersing R. parkeri-infected A. tigrinum ticks. Additionally, we report for the first time a rickettsial agent infecting I. pararicinus ticks.Algumas espécies de Rickettsia transmitidas por carrapatos são reconhecidos como patógenos humanos na Argentina. Este presente trabalho avaliou a infecção por Rickettsia em carrapatos coletados em aves passeriformes, durante 2011-2012, em duas ecorregiões da Argentina. Os carrapatos foram processados pela reação em cadeia da polimerase (PCR) e sequenciamento de DNA de dois genes de Rickettsia: gltA e ompA. Ao todo, 594 amostras de carrapatos (532 larvas e 62 ninfas), representando pelo menos 4 espécies (Amblyomma tigrinum, Ixodes pararicinus, Haemaphysalis juxtakochi, Haemaphysalis leporispalustris), foram avaliadas. Pelo menos uma larva de A. tigrinum, coletada de Coryphospingus cucullatus no Chaco Seco, estava infectada com Rickettsia parkeri, enquanto pelo menos 12 larvas e 1 ninfa de I. pararicinus, coletadas de Troglodytes aedon, Turdus amaurochalinus, Turdus rufiventris, C. cucullatus e Zonotrichia capensis estavam infectadas com Rickettsia sp., geneticamente relacionada a vários endossimbiontes riquetsiais de carrapatos do complexo Ixodes ricinus. R. parkeri é reconhecidamente um patógeno humano em alguns países americanos, incluindo a Argentina, onde um estudo recente incriminou A. tigrinum como um provável vetor. Aves poderiam desempenhar um papel importante na dispersão de carrapatos A. tigrinum infectados por R. parkeri. Em adição, relata-se pela primeira vez a infecção por Rickettsia em I. pararicinus.Fil: Flores, Fernando Sebastián. Universidad Nacional de Córdoba. Facultad de Medicina.

Postpartum Hemorrhage Detection Device
During a cesarean section, blood loss greater than 1000 mL is classified as a hemorrhage. Quantified blood loss methods are used to detect hemorrhage, however existing methods are inaccurate and time consuming. Our proposed device is inserted vaginally during a cesarean section to collect and quantify blood lost via the cervix during and after the procedure. The device also applies light suction to the uterus, which can aid in uterus collapse and decrease the risk of postpartum hemorrhage
