Webcam technology on neonatal wards—examining the objective and subjective workload of nurses: a combined observational and survey study

BackgroundThis study was conducted to estimate the additional objective and perceived workload of nurses resulting from the use of webcams. The successful implementation of webcam technology into routine care requires an analysis to prevent adverse events of increased nursing workload.MethodsThe study took place on three neonatal wards in two University Hospitals in Germany. In the first Hospital, the study was conducted from February to July 2021; in the second one it was conducted between June and November 2021. Data were collected using a combined approach of a standardised diary questionnaire study and passive observations. The participants were accompanied in their daily work and their activities were recorded 65 nurses participated.Results2,031 h were observed in 1,630 observation blocks. In 14.74% of the observation blocks webcam activities were detected. The extent to which the nurses had webcam-related additional workloads was rated as no additional workload in 82.16% of the daily questionnaires (n = 1,026).ConclusionThe observed low workload due to the webcams is in line with the nurses’ perception. The observational data revealed, on a number of different analysis levels, that a limited additional workload was generated. There was no decrease in activity performance observed and no clear indication for interruptions due to the webcam-related activities for the nurses. However, it is important to raise awareness about the individual workload levels for the successful implementation. Additional education programs can be provided for nurses.Trial registrationThe Neo-CamCare study is registered at the German Clinical Trials Register. DRKS-ID: DRKS00017755

Scheduling of offshore wind farm installation using simulated annealing

This paper focuses on the scheduling problem in the offshore wind farm installation process, which is strongly influenced by the offshore weather condition. Due to the nature of the offshore weather condition, i.e., partially predictable and uncontrollable, it is urgent to find a way to schedule the offshore installation process effectively and economically. For this purpose, this work presents a model based on Timed Petri Nets (TPN) approach for the offshore installation process and applies simulated annealing algorithm to find the optimal schedule

Influence of river discharge on phytoplankton structure and nutrient concentrations in four tropical semiarid estuaries

This study evaluated changes in phytoplankton and nutrients after an increase in river discharge in four estuaries of northeastern Brazil. Samples were taken during a markedly freshwater-deprived period (Nov/2010, dry season), and during a rainy season (May/2011). While two estuaries are located in urban areas (Ceará - CE and Cocó - CO), the others are markedly freshwater-deprived (Pacoti - PAC and Pirangi - PIR). Our findings indicate that increased freshwater had opposing effects on estuaries impacted by anthropogenic discharges (CO, CE and PIR) compared with the other, less impacted (PAC). In CO and CE, the freshwater flow during the rainy period had a nutrient diluting effect and controlled phytoplankton blooms. In PIR, only phosphorus and inorganic nitrogen decreased in the rainy season. In contrast, an increase of all nutrients was observed in PAC, and of TN in PIR, followed by an increase in phytoplankton biomass. In the rainy season, eutrophic freshwater species dominated in all the estuaries. In the dry season, blooms of Cryptomonas/Rhodomonas and Synechocystis aquatilis were, respectively, observed in CE and CO. Also in the dry season, PAC and PIR had a predominance of marine species under a condition of hypersalinity. Canonical correspondence analysis suggested the variation observed for salinity, silica, and TN are the main driver of phytoplankton structure.Neste estudo foram avaliados os efeitos do aumento da vazão fluvial sobre o fitoplâncton e os nutrientes em quatro estuários do Nordeste do Brasil. Para isso, foram coletadas amostras durante um período de forte déficit hidrológico (Nov/2010, período seco), e durante um período chuvoso (maio/2011). Dois estuários estão localizados em áreas urbanas (Ceará - CE e Cocó - CO) e dois têm forte déficit de água doce (Pacoti - PAC e Priangi - PIR). Os efeitos do aumento da descarga fluvial foram diferentes entre os que recebem descargas antrópicas (CO, CE e PIR) e aquele menos impactado (PAC). No CO e CE, o fluxo fluvial no período chuvoso diluiu os nutrientes e controlou as florações fitoplanctônicas. No PIR, o fósforo e o nitrogênio inorgânico decresceram neste período. Foi observado um aumento de todos os nutrientes no PAC, e de NT no PIR, seguidos de um aumento do fitoplâncton. No período chuvoso, espécies dulcícolas de ambientes eutróficos dominaram nos estuários. No período seco, observaram-se florações de Cryptomonas/Rhodomonas (CE) e Synechocystis aquatilis (CO). No período seco, sob a condição de hipersalinidade, predominaram espécies marinhas no PAC e PIR. A Análise de Correspondência Canônica sugeriu a salinidade, a sílica e o NT como os principais responsáveis pela variação do fitoplâncton

Beyond allyship:Motivations for advantaged group members to engage in action for disadvantaged groups

White Americans who participate in the Black Lives Matter movement, men who attended the Women’s March, and people from the Global North who work to reduce poverty in the Global South—advantaged group members (sometimes referred to as allies) often engage in action for disadvantaged groups. Tensions can arise, however, over the inclusion of advantaged group members in these movements, which we argue can partly be explained by their motivations to participate. We propose that advantaged group members can be motivated to participate in these movements (a) to improve the status of the disadvantaged group, (b) on the condition that the status of their own group is maintained, (c) to meet their own personal needs, and (d) because this behavior aligns with their moral beliefs. We identify potential antecedents and behavioral outcomes associated with these motivations before describing the theoretical contribution our article makes to the psychological literature

Impacto estético de edifícios altos e propostas de intervenção para setores do 4º. distrito de Porto Alegre

O objetivo deste artigo é analisar o impacto estético de edifícios altos através da percepção de usuários do espaço urbano a partir de distintos pontos de observação e, com base nos resultados obtidos, analisar duas propostas acadêmicas (trabalhos de conclusão do curso de Arquitetura e Urbanismo) de intervenção urbana para setores do 4º. Distrito de Porto Alegre. A coleta de dados foi realizada através de questionários aplicados via internet para usuários da cidade de Porto Alegre - Brasil, divididos em três grupos de respondentes: arquitetos; não arquitetos com curso universitário completo e pessoas sem curso universitário concluído ou iniciado. Os resultados indicam que os impactos dos edifícios altos na estética urbana podem ser percebidos de diferentes formas, de acordo com a distância da qual são observados. Quando visualizados ao nível dos olhos o impacto tende a ser mais negativo do que quando observados à distância – no skyline da cidade.The purpose of this paper is to analyze the aesthetic impact of tall buildings through the perception of users of the urban space from different observation points and, based on the results, analyze two academic proposals (completion of work of the Architecture and Urbanism course) urban intervention for sectors in the 4th District of Porto Alegre. Data were collected through questionnaires made available via the Internet to users of urban space of Porto Alegre - Brazil, divided into three groups of respondents: architects; nonarchitects college graduates and people non college graduates. The results indicate that the impacts of tall buildings in urban aesthetics can be perceived in different ways, according to the distance from which they are observed. When observed at level eye the impact tends to be more negative than when observed from a distance – on the city skyline

Ein innovatives Lehr- / Lernkonzept für Promovierende

Für die Zielgruppe der Promovierenden wird ein innovatives Lehr-/ Lern-Konzept zur Förderung der Informations- und Medienkompetenz vorgestellt. Die Medienrecherche mit Google-artigen Recherchesystemen ist aufgrund der Digitalisierung vieler Medienressourcen beliebt und scheint einfach zu sein, birgt in der Praxis jedoch viele Fehlerquellen. Daher gewinnt die gezielte Vermittlung effektiver Recherchetechniken zunehmend an Bedeutung und stellt für Bibliothekare und Bibliothekarinnen eine Chance dar, um spezifische Lernangebote zu konzipieren und für Bibliotheken, sich als Lernorte neu zu positionieren. Das übergeordnete Ziel des hier vorgestellten Veranstaltungskonzepts stellt die selbständige Durchführung eines Systematic Literature Review dar. Das Kursprogramm für die Promovierenden ist dabei an aktuellen didaktisch-methodischen Vorgaben orientiert und exemplarisch auf den Forschungsprozess einer naturwissenschaftlichen Fachdisziplin (hier: Geowissenschaften) abgestimmt. Das multimediale Angebot ermöglicht individuelle Lernpfade, ist nachhaltig nutzbar und auf andere Disziplinen übertragbar

Large-Scale Differential Proteome Analysis in Plasmodium falciparum under Drug Treatment

Proteome studies contribute markedly to our understanding of parasite biology, host-parasite interactions, and mechanisms of drug action. For most antimalarial drugs neither mode of action nor mechanisms of resistance development are fully elucidated although this would be important prerequisites for successfully developing urgently required novel antimalarials. Here, we establish a large-scale quantitative proteomic approach to examine protein expression changes in trophozoite stages of the malarial parasite Plasmodium falciparum following chloroquine and artemisinin treatment. For this purpose SIL (stable isotope labeling) using 14N-isoleucine and 13C6,15N1-isoleucine was optimized to obtain 99% atomic percent enrichment. Proteome fractionation with anion exchange chromatography was used to reduce sample complexity and increase quantitative coverage of protein expression. Tryptic peptides of subfractions were subjected to SCX/RP separation, measured by LC-MS/MS and quantified using the novel software tool Census. In drug treated parasites, we identified a total number of 1,253 proteins, thus increasing the overall number of proteins identified in the trophozoite stage by 30%. A relative quantification was obtained for more than 800 proteins. Under artemisinin and chloroquine treatment 41 and 38 proteins respectively were upregulated (>1.5) whereas 14 and 8 proteins were down-regulated (<0.5). Apart from specifically regulated proteins we also identified sets of proteins which were regulated as a general response to drug treatment. The proteomic data was confirmed by Western blotting. The methodology described here allows for the efficient large-scale differential proteome analysis of P. falciparum to study the response to drug treatment or environmental changes. Only 100 µg of protein is required for the analysis suggesting that the method can also be transferred to other apicomplexan parasites

Fragmentos eloquentes

Qual o valor de um fragmento sem contexto? Partindo deste questiona-mento, proponho a reflexão acerca das louças do acervo arqueológico do Museu Paranaense, argumento inserido na observação das relações entre arqueologia e história construída dentro desta instituição em âmbitos diversos – publicações, estudo do acervo e exposição. Como recorte, este trabalho visa considerar a potencialidade do estudo do material categorizado como louça arqueológica diante da separação a que é submetida em relação a peças das coleções associadas ao setor de História. Estabelecidas as fronteiras, a restrição na produção de conhecimento inflige a dúvida: o silên-cio dos fragmentos é um dado factual ou sintoma de conservadorismo? Afinal, muito se disse sobre a incapacidade de falar das fontes – fala, sim, o pesquisador. O silêncio da problematização da louça arqueológica do MP tem sua procedência na mudez que lhe foi imposta pelo tratamento marginal. Enfim, o objetivo aqui é colocar em debate as atitudes cerceadoras que impomos aos nossos objetos de estudo, muitas vezes cau-sadas pela resistência em olhar além de metodologias naturalizadas de tratamento das evidências. Não pretendo oferecer a fórmula ideal para interpelar registros do passa-do, mas plantar a inquietação necessária para enriquecer o universo de possibilidades interpretativas de resquícios insignificantes que transbordam de significado. Abstract:What’s the value of a fragment without a context? From that question I propose to consider the pottery collection from the Paranaense Museum, from a perspective regarding the relationship between archaeology and history built by this institution in different realms – publications, collection studies and exhibits. As an extract, this paper aims the particular potential behind the study of the artifacts categorized as ‘archaeological pottery’ given its separation from the objects associated with the History department. Once the frontiers are set, the restriction on the production of knowledge leaves the doubt: is the silence of the fragments a given fact or a symptom of conservatism? After all, a lot has been said about the inability of sources to speak – it is the researcher whom really does the speaking. The silence behind the questioning of the archaeological pottery from PM has its origin in the muteness set by the marginal treatment it has received. Ultimately, the goal of this paper is to start debating the restrictive attitudes which we impose to our objects of study, caused many times by our resistance to look beyond naturalized methodologies of processing evidence. I do not wish to establish an ideal formula for dealing with the remains of the past, but to encourage the much needed unrest to enrich the universe of possible interpretations of those meaningless vestiges which overflow with meaning

Fronteiras de uma discussão: arqueologia histórica de uma fábrica de louças

Em voga nos debates acadêmicos dos últimos anos, a interdisciplinaridade exige um esforço de reflexão considerável ao pesquisador cujo trabalho almeja tal classificação. A arqueologia histórica, área que frequentemente reivindica sua natureza híbrida, oferece um amplo leque de possibilidades ao desenvolvimento de temas do passado recente. Contudo, ainda são perceptíveis as limitações impostas ao diálogo em estudos ligados, por exemplo, à imigração e à industrialização, como se pretende demonstrar no caso da Fábrica de Louças Colombo. O objetivo deste trabalho é expor, além dos resultados obtidos na pesquisa, as nuances e os entraves que se apresentaram no decorrer do projeto, ilustrando o quanto a interdisciplinaridade é teorizada e incentivada, mas nem sempre aceita em sua totalidade. Acredito que, em especial no que tange ao século XX, a intersecção das disciplinas não seja apenas bem vinda, como necessária para fornecer um quadro que contemple o passado sem subestimar sua complexidade e sem ignorar suas ambiguidades
