O presente estudo teve como objetivo desenvolver uma nova proposta de uso de um biomonitor na identificação de fontes emissoras de metais no meio ambiente. Foi selecionada a espécie de siri Callinectes danae como biomonitor e o estuário de Santos como área de estudo. Numa primeira etapa e considerando que o siri é um organismo bentônico, foi realizada uma avaliação preliminar do teor de metais no sedimento do estuário. Em seguida, foi realizada uma avaliação preliminar do teor de metais nos diferentes tecidos de indivíduos coletados na região (brânquias, hepatopâncreas e músculos). Baseado nos experimentos anteriores, foi proposto um modelo de distribuição dos metais entre os tecidos e destes em relação aos sedimentos. A validação deste modelo de distribuição (assinatura química) foi realizada por meio de um conjunto de procedimentos que visaram testar: 1) a robustez em função do tempo; 2) a especificidade para a região de estudo; 3) a sensibilidade às alterações dos níveis de metais em cada tecido. A partir deste modelo, foram identificados indícios para atribuição de fontes emissoras de metais. Desta forma, concluiu-se que, para a região do estuário de Santos, o siri da espécie C. danae pode ser utilizado como um biomonitor. O modelo proposto foi eficaz, uma vez que foi capaz de responder de forma conclusiva-positiva a todos os testes realizados na sua validação, confirmando esta espécie como um biomonitor definitivo para região. A robustez do modelo irá aumentar com novas coletas e a realimentação do banco de dados. / This study aimed to develop a new methodology for the use of a biomonitor in the identification of metal discharges in environmental evaluations. Crabs of Callinectes danae species were used in an evaluation conducted in the Santos Estuarine System. In the first experiment and since C. danae is a benthic species, a preliminary assessment of the metal concentrations in sediment samples collected in the Santos Estuarine System was performed. Subsequently, a preliminary assessment of metal concentrations in the C. danae tissues was also peformed. The last experiment aimed to identify a chemical fingerprint for the Santos Estuarine System.The development of validation procedures for this model (chemical fingerprint) was conducted and aimed to test: 1) the stability of this model through time; 2) its local specificity for the Santos Estuarine System; 3) the sensibility of this model due to modifications in the metal concentrations in each tissue (gills, hepatopancreas and muscles). By the use of this model, it was possible to identify the sources of metal emissions. According to the results, C. danae can be used as a biomonitor for the Santos Estuarine System. The established model was able to responde in a positive-conclusive way to all the tests performed in its validation, confirming this species as a definitive biomonitor for this area. Thus, the stability of this model will increase with new sampling campaings and consequently introduction of new information in the database.

Att välja vilken eller vilka röststyrningstjänster man som företag vill stödja kan i dagens läge vara ett svårt val att göra. Det kan även var så att man inte har resurser att göra två olika implementationer. I den här undersökningen tittar vi på om det finns ett bra sätt att göra en implementation som kan hantera fler än en röststyrningstjänst. Tjänsterna vi har fokuserat på i undersökningen är Amazon Alexa och Google Assistant.

Your New Best Friends: An Exploration of Furby, Siri and Other Sociable Electronics is focused around interactive electronic systems and the effect these systems can have on our human psyches. My work focuses on two particular periods of development: the late 80’s to early 90’s, and the 2010’s to present. One period represents my childhood and the other my early adulthood. By comparing the two I can examine trends in the ways we engage with robotics and can better understand the ubiquity of electronically mediated interactions today. I utilize these new understandings to manipulate the capabilities of devices from both periods to create pieces that communicate care in a new way, sparking a moment of joy for the viewer while also increasing the awareness of the failings of devices when compared with true human interaction.

Syftet med uppsatsen är att undersöka Siri Derkerts och Vera Nilssons betydelse för att vi har konst i tunnelbanan idag. SL kallar tunnelbanan för ”världens längsta konstutställning” och drygt 200 konstnärer har bidragit till utsmyckningen och gestaltningen av de semi-offentliga rum som tunnelbanan utgör. Den första oktober 1950 invigs den första tunnelbanesträckan och dessa nya tunnelbanestationer hade ingen konst. Debatten om konstsmyckningar i tunnelbanan tog fart redan innan den första tunnelbanestationen öppnade. 1955 tog Stockholms stadsfullmäktige beslutet att det ska vara konst i tunnelbanan. Staden och Stockholms spårvägar utlyste en tävling 1956 om vem som får smycka T-Centralen. Nilsson och Derkert, som initierat tävlingen, fanns bland de konstnärer som fick uppdraget att smycka T-Centralen som invigdes 1957: Vera Nilsson med mosaikpelaren Det Klara som trots allt inte försvinner (1957) och Siri Derkert med Linje (1958) en pelare i betong, även kallad Kvinnopelaren.

Blood symbolism is a phenomenon that is commonly processed in literature, especially within the fantasy genre. Siri Pettersen’s fantasy novel Kraften (2016) does not make an exception from this tradition. In this essay I present the different levels of blood symbolism and textual aesthetics within Kraften while focusing on four perspectives: violence, sexual acts, bodily functions and rituals. As a result, I find that blood symbolism has a profound connection to Pettersen’s characters and fantasy universe as a whole; that the particular force affecting the earth can represent the Norse giant Ymir’s symbolic blood. I also find that the contemporary view of blood – menstrual or other – is impacted by ancient cultural traditions and beliefs among the very first humans walking the earth. And finally, that blood symbolism operates very much like the first law of thermodynamics in fantasy literature: it cannot disappear or be destroyed, only be recreated into new forms.

Watu wa pwani ya Afrika Mashariki wanaojumuisha vikundi vingi wana historia ndefu ya mitagusano na makundi mengine yakiwemo ya bara na wageni kutoka sehemu mbalimbali za ulimwengu. Mitagusano hiyo ya wapwani na wengine pamoja na athari zake ni mojawapo ya maudhui makuu ambayo Rocha Chimerah anashughulikia katika kazi zake zote. Makala hii inachanganua maudhui na vipengele vya fani vya kazi za mwandishi huyu ili kubainisha jinsi anavyoshughulikia suala lililotajwa hapo juu. Katika kufanya hivyo, makala inatathmini uhalisi wa kijamii na kihistoria unavyowakilishwa na kazi za Chimerah. Japo kazi zote za Chimerah zitarejelewa, zile za karibuni zaidi zitapewa kipaumbele.

As the transportation sector fully integrates information technology, transit agencies face decisions that expose them to new technologies, relationships and risks. Accompanying a rise in transit-related web and mobile applications, a set of competing real-time transit data standards from both public and private organizations have emerged. The purpose of this research is to understand the standard-setting processes for these data standards and the forces that move the transit industry towards the widespread adoption of a data standard. This project will analyze through case studies and interviews with members of standard-setting organizations the development of three real-time transit data standards: (1) the development of the General Transit Feed Specification Realtime (GTFS-realtime), (2) the Service Interface for Real Time Information (SIRI), and (3) Transit Communications Interface Profiles (TCIP). The expected outcome of this research is an assessment of federal policy on standards development as well as an analysis of current and future trends in this sector—both technical and institutional. The results will inform federal transit policy and future action in standards-setting and intelligent transportation systems (ITS) requirements, identifying the potential catalysts that will increase the effectiveness of federal- and agency-level programs.

Spatial and seasonal distribution of C.danae in the Northwest Vitoria Bay, southeast Brazil, were investigated by night trawl through monthly sampling during one year (Dec/00 to Nov/01 N=72), with physico-chemical parameters of water measured in situ on each of the six sampling stations, located through the bay on three areas sub-divided in shallow and deep ones, along a transversal axis. A total of 3879 individuals was collected, being 2537 females (1147 adults, 318 ovigerous and 1072 juveniles) and 1339 males (444 adults and 895 juveniles). Mean carapace width (including lateral spines) at sexual maturity was 9,13 cm for males and 8,05 cm for females, and sex ratio was 1,89♀::1♂. Ovigerous females occurred the whole year (except on Nov/01), with higher densities on February, July and October/01, almost exclusively in the southern part of sampling area, which showed higher salinities and lower temperatures due to coastal waters entering throw the harbor channel. Adult males and juveniles of both sexes occurred mainly in north and central parts of sampling areas, with lower salinities and higher water temperatures due to the discharges of Santa Maria and Bubu rivers; their densities were higher on December/00, October and November/01. Adult females showed homogeneous densities along the bay and sampling months / Os siris Callinectes danae (Portunidae) são abundantes nos estuários brasileiros, sendo bastante utilizados na pesca artesanal. O objetivo deste trabalho é avaliar a distribuição espacial e temporal e a estrutura da população de C.danae na Baía Noroeste de Vitória/ES, sudeste do Brasil, investigando as proporções entre os sexos, a distribuição de tamanhos dos exemplares e a ocorrência de fêmeas ovígeras. Amostras mensais noturnas (N=72) foram coletadas utilizando rede de arrasto por tração mecânica, com malha de 25 mm, entre dezembro de 2000 e novembro de 2001, em seis estações distribuídas em três áreas ao longo do eixo longitudinal da baía, sendo uma amostragem na porção rasa (Coroa) e outra na porção profunda (Canal). Profundidade, salinidade, temperatura e oxigênio dissolvido na água foram medidos in situ em cada ponto amostral. Um total de 3876 exemplares foi coletado, sendo 2537 fêmeas (1147 adultas não ovígeras, 318 ovígeras e 1072 juvenis) e 1339 machos (444 adultos e 895 juvenis). A largura da carapaça (entre os extremos dos espinhos laterais) da primeira maturação sexual foi de 9,13 cm para machos e 8,05 cm para fêmeas, a razão sexual foi de 1,89♀:1♂ e a densidade média de indivíduos no período foi de 1,66 x 10-2m2. Fêmeas ovígeras ocorreram ao longo de todo o período (exceção novembro/2001), com picos de densidade em fevereiro, julho e outubro de 2001, concentradas quase exclusivamente na porção sul da área amostral, sujeita a um maior aporte de águas salinas e de menores temperaturas provenientes da zona costeira pelo Canal do Porto. Machos adultos e juvenis apresentaram maiores densidades nos meses de dezembro de 2000 e outubro e novembro de 2001, ocorrendo nas porções norte e central da área amostral, onde predominaram menores salinidades e maiores temperaturas, sob influência da descarga dos rios Santa Maria e Bubu. Fêmeas adultas apresentaram distribuição homogênea ao longo do período e das áreas amostrais

Voice assistants are a remarkable example of the potential for AI to become further entwined with social life. However, they are produced by some of the world’s largest tech corporations and are rooted in capitalistic processes that depend on user data. This thesis presents a qualitative exploratory study of voice assistants. Through a combination of interviews and theoretical analysis, it focuses on participants’ perceptions and experiences with these AI agents and how they are embedded in the bigger picture of surveillance capitalism. The findings reveal the physical characteristics and personality traits that participants in this study ascribe to voice assistants, highlighting the implications of treating voice assistants as personified agents and the factors contributing to these perceptions. Further, this thesis examines how surveillance capitalism is present in participant interactions with these technologies and identifies how its reach into people’s lives is provoked by their design and background contexts. Lastly, it provides an overview of corporate power in the tech industry and how the structural, cultural, and political circumstances enable and legitimize big tech’s authority in digital environments and how this situates the individual and their capacity to contend with technological issues. / Graduate / 2023-07-12
