Sex Transm Dis
No full textDisease intervention specialists (DIS) are the cornerstone of public health. However, the incremental gains of DIS-led interventions are difficult to detect at the population level. Health departments attempt to quantify the impact of key DIS activities through performance measures that assess how many and how quickly both patients are interviewed, and contacts are notified, tested, and treated. However, DIS work encompasses more than case finding and existing performance measures may not capture the full value DIS provide to health departments. In this article, we first describe how DIS investigations and contact tracing are conducted for sexually transmitted diseases and other communicable diseases to understand how the definition of effectiveness may vary by disease. Then, we examine the benefits and limitations of traditional performance measures using syphilis investigations as an example. Recognizing the limits of existing measures will improve our understanding of DIS impact and assist in the development of new measures of effectiveness that better represent the totality of DIS work.CC999999/ImCDC/Intramural CDC HHSUnited States

Effect of DIS Attack on 6TiSCH Network Formation
No full textThe 6TiSCH standard provides minimum latency and reliability in mission-critical IoT applications. To optimize resource allocation during 6TiSCH network formation, IETF released the 6TiSCH minimal configuration (6TiSCH-MC) standard. 6TiSCH-MC considered IETF's IPv6 Routing Protocol for Low power and Lossy network (RPL) as a routing protocol for both upward and downward routing. In RPL, new joining nodes or joined nodes transmit DODAG Information Solicitation (DIS) requests to get routing information from the network. However, we observe that malicious node(s) can severely affect 6TiSCH networks by sending multiple DIS requests. In this letter, we show and experimentally evaluate on real devices the impact of the DIS attack during 6TiSCH networks formation. We show that the attacker does not need expensive resources or access to the network's sensitive information to execute the DIS attack. Our testbed experiments show that the DIS attack significantly degrades the nodes' joining time and energy consumption, increasing them by 34% and 16%, respectively, compared to normal functioning during 6TiSCH network formation.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Cyber Securit
Human behaviour should be recorded in (dis)comfort research
No full text(Dis)comfort research that has no information on behaviour of the participants can be considered as incomplete, as major influencing factors could be missed. For (dis)comfort research it is important to capture influential factors such as context and task/activity, posture, movement, (distracting) stimuli and time, as these factors have influence on the experienced (dis)comfort. Recording the behaviour allows for better evaluation of and comparison between studies, contributing to an increase of scientific knowledge on (dis)comfort.Mechatronic DesignApplied Ergonomics and Desig
Experimental infection and horizontal transmission of Piscirickettsia salmonis in freshwater-raised Atlantic salmon, Salmo salar L.
No full textExperimental infections with Piscirickettsia salmonis via intraperitoneal (IF), oral (PO) and gill (GS) routes were compared, and the importance of physical contact in the horizontal transmission of this organism was investigated. Atlantic salmon, Salmo salar L., under-yearling parr raised in fresh water were used in this study. Samples of liver, kidney, spleen, gill and brain were collected weekly for 5 weeks after challenge, and were examined using the indirect fluorescent-antibody technique (IFAT). The pathogen was transmitted horizontally to fish with and without physical contact. However, transmission of P. salmonis occurred significantly more rapidly among fish with physical contact. Mortalities occurred in 50% of fish experimentally challenged with P. salmonis and their cohabitants. The estimates of the relative risk of dying demonstrated that fish challenged by the IP and GS routes had a significantly higher probability of dying than fish challenged by the PO route (P < 0.005). Contact cohabitants with infected fish had a higher probability of death than non-contact cohabitants (P < 0.005). The sequential studying using IFAT indicated that a haematogenous pattern of infection occurred among fish infected by oral and gill routes, or by cohabitation. This was different from the capsular (serosal) infection pattern observed in intraperitoneally inoculated fish. Piscirickettsia salmonis was observed within the cytoplasm of leucocytes and renal tubules, the latter indicating that elimination of this pathogen through the urine may be possible. Aeromonas salmonicida was also detected (by IFAT) in some of the fish exposed to P. salmonis, suggesting that P. salmonis may cause immunosuppression, and thus, increase the susceptibility of the host to other pathogens.PT: J; CR: *FAO, 1994, ANN STAT DAT *SAS I, 1988, SAS STAT GUID PERS C AHNE W, 1978, J FISH DIS, V1, P265 BAKKE TA, 1992, DIS AQUAT ORGAN, V13, P63 BRANSON EJ, 1991, J FISH DIS, V14, P147 BRAVO S, 1989, FHS AFS NEWSLETTER, V17, P3 BROCKLEBANK JR, 1993, CAN VET J, V34, P745 BRUNO DW, 1986, J FISH DIS, V9, P523 CHILMONCZYK S, 1980, FISH DIS 3 COOPERATI, P188 CVITANICH JD, 1991, J FISH DIS, V14, P121 EFFENDI I, 1995, B EUROPEAN ASS FISH, V15, P115 EVANS DH, 1993, PHYSL FISHES, P315 FRYER JL, 1990, FISH PATHOL, V25, P107 FRYER JL, 1992, INT J SYST BACTERIOL, V42, P120 GAGGERO A, 1995, J FISH DIS, V18, P277 GARCES LH, 1991, DIS AQUAT ORGAN, V11, P93 GRACES LH, 1994, P INT S AQ AN HLTH S HSIUNG GD, 1994, HSIUNGS DIAGNOSTIC V, P46 KANNO T, 1989, J AQUAT ANIM HEALTH, V1, P2 LANNAN CN, 1991, J AQUAT ANIM HEALTH, V3, P229 LANNAN CN, 1994, J FISH DIS, V17, P545 LEE ET, 1980, STATISTICAL METHODS MENDEZ R, 1995, AQUANOTICIAS INT, V24, P6 MURRAY CB, 1992, DIS AQUAT ORGAN, V12, P91 OLFRET ED, 1993, GUIDE CARE USE EXPT OLSEN AB, 1993, NORSK FISKEOPPDRETT, V12, P40 RODGER HD, 1993, J FISH DIS, V16, P361 TRUST TJ, 1986, ANNU REV MICROBIOL, V40, P479 WOLDEHIWET Z, 1993, RICKETTSIAL CHLAMYDI, P1; NR: 29; TC: 17; J9: J FISH DISEASES; PG: 10; GA: YK288Source type: Electronic(1
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Staging dis-placement
No full textIn the project ‘To You, To You, To You: Love Letters to a (Post)Europe’ (2018) (https://www.toyoutoyoutoyou.com/ ), curator-researcher Lisa Alexander invited artists to gather and to respond with the action, idea or form of a love letter. My action-response: ‘To You To Me’ (2018) used cord, fabric, and trust, inviting the audience to perform an unconditional act of love towards me, the performer on stage. My ‘love letter’ acknowledged my feeling of displacement and also acknowledged my need to overcome this feeling by being unconditionally lifted and supported as a European citizen living in the UK during this precarious historical moment.
If places are shaped by significant historic moments (Hannah, 2011: 56), they are also shaped by the language and the words we choose to define those moments. Cognitive psychologist Raymond Gibbs, based on a series of empirical experiments, concludes that the imaginative way we understand metaphors is contained by our felt experience so we ‘recreate what it must be like to engage in similar actions’ (2006: 438). This sensorimotor and felt understanding of ‘imagining of metaphorical actions’ applies to all actions in metaphors, even physically impossible ones (2006: 444). With To You To Me’, I am situating this imaginative understanding between metaphorical language of feelings and the performance space and I am embodying or rather en-spacing the metaphor of my feeling of dis-placement.
By doing so this action-scenography developed as a conceptual engagement with the control of a place, one that is generously shared but becomes awkwardly uncomfortable when the weight of the ropes in the hands starts feeling heavy. As a scenography making strategy, en-spacing the metaphor of dis-placement on stage has transformed it from a feeling to an action
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
