Carbon Steel Corrosion and Cathodic Protection Data in Deep North Atlantic Ocean
Authors: Diler Erwan , Larché Nicolas , Thierry Dominique
Published: August 2020

Many parameters may influence the corrosion and the cathodic protection current demand in natural seawater. These are potential, temperature, dissolved oxygen content, biofilm and fouling activity, hydrostatic pressure, and calcareous deposit formation. In this study, the influence of the exposure depth on the corrosion, cathodic protection current demand, and nature of the calcareous deposit formed on carbon steel was investigated at 1,020 m and 2,020 m depth. For this purpose, a set of coupons, cathodic protection, and environmental sensors were exposed in Azores in the Atlantic Ocean for 11 months. The higher corrosion rate and current density observed at 1,020 m can be explained by the higher temperature and oxygen diffusion. The cathodic current demand decrease with time can be attributed to the calcareous deposit formation. The current densities after 11 months are in agreement with the literature with 143 mA/m2 and 124 mA/m2 at 1,020 m and 2,020 m depth. Calcareous deposits formed, characterized by Raman spectroscopy, x-ray diffraction, and scanning electron microscopy/electron dispersive x-ray spectroscopy, highlight (i) the favored formation of calcite and hydrocalcite at the expense of aragonite in deep and cold water, (ii) the presence of a thin deposit after 11 months, (iii) the decrease of the Ca/Mg ratio with immersion depth, (iv) the presence of CaMgCO3 compounds, and (v) a higher decrease of the current demand with time in deep water, suggesting the formation of a more protective deposit. The capacity for aluminum-gallium and aluminum-indium galvanic anode were in agreement with the literature for long-term exposures.
Trabalhadores no mundo: marinheiros indianos, c. de 1870-1940
Authors: Balachandran Gopalan
Published: August 2020

A expansão da marinha mercante britânica na era do vapor foi estimulada pelo emprego de tripulações do subcontinente indiano. Entre os mais mal pagos do mercado, os marinheiros indianos eram os trabalhadores internacionais pioneiros que compunham quase um terço da força de trabalho na marinha britânica em 1937. Rotulados genericamente como “lascars”, seu emprego em regimes semelhantes a contratos firmados reforçou o status de “coolies”, promoveu a desoneração/desqualificação do trabalho marítimo e instituiu hierarquias racializadas no trabalho na marinha mercante, que perduram até hoje dentro e fora do setor. Este artigo apresenta um breve relato das condições de vida e de trabalho dos marinheiros subcontinentais, explora a atitude dos sindicatos britânicos em relação ao emprego dessas tripulações e destaca sua crucial contribuição para a expansão da navegação imperial britânica e, de maneira mais geral, para a dimensão marítima do poder imperial britânico.
La memoria como 'factum' metafísico en la filosofía de la expresión de Giorgio Colli
Authors: Boqué Marc
Published: August 2020

En el presente artículo analizamos la relación que mantienen la memoria y el conocimiento en el marco de la obra Filosofía de la expresión de Giorgio Colli. Una correlación que nos permitirá abordar una gnoseología en la que la razón, recuperando el viejo sentido griego, terminará concibiéndose como un discurso destinado a «reevocar» otra cosa y, al mismo tiempo, como la señal que subrayará la degradación respecto a ese límite metafísico que manifestará. Este falseamiento que exhibirá el conocimiento entendido en cuanto expresión y en estrecha concomitancia con la memoria defendemos que será el que finalmente articulará una original crítica a la teoría de la representación moderna, cuyo valor pensamos que tendría que otorgar a Colli un papel significativo entre los pensadores contemporáneos.
Nietzsche, la filología, y la filosofía: conjunciones en el horizonte de la crítica
Authors: Carrión Arias Rafael
Published: August 2020

La filosofía nietzscheana es una filosofía filológica. Por debajo del legado del Nietzsche de madurez prevalece una base crítico-metodológica descubierta por él en sus años de práctica filológica y de la que se desprende una mirada filosófica profundamente original. Este artículo pretende mostrar las razones de esa coincidencia en un recorrido de continuidad a través del problema de la crítica.
Hegel y las inhibiciones lectoras de Heidegger. (Las desventuras de la diferencia en la lectura heideggeriana de Hegel)
Authors: Fabo Lanuza Javier
Published: August 2020

Se trata de evidenciar los presupuestos de la lectura heideggeriana de Hegel. Hegelianos y antihegelianos asumen estos presupuestos como algo incontestable; unos movidos por la necesidad de combatir el retorno del espectro hegeliano, otros por la necesidad de liberarlo de su estigma ontoteológico. El resultado es una interpretación reduccionista de la filosofía de Hegel, que regala la mayoría de sus conceptos fundamentales a la crítica heideggeriana, al considerarlos contaminados por el totalitarismo de la clausura y de la identidad. Una interpretación como ésta descansa, sin embargo, en presupuestos muy cuestionables que conviene explicitar, y entre los que cabe destacar la interpretación heideggeriana de la Aufhebung como superación de la diferencia. El propósito de este artículo es perseguir las aventuras de la diferencia en algunos puntos clave de la dialéctica hegeliana (fundamentalmente: la figura de la Conciencia desdichada y la categoría lógica de la Reflexión) que Heidegger trata insatisfactoriamente en su comentario, sirviéndose de maniobras sospechosas que pueden leerse como síntomas de una inhibición.
La elaboración de la noción de «estado de naturaleza pura» en el 'Tractatus de gratia' de Francisco Suárez. La perspectiva de André de Muralt

Al elaborar la noción de un «estado de naturaleza pura» como dotada de un realidad objetiva propia, Francisco Suárez (1548-1617) le iba a proporcionar a la filosofía política moderna la herramienta conceptual de la que los filósofos y iusnaturalistas de los siglos XVII y XVIII que se inscriben en su estela se valdrían para desarrollar su pensamiento político y jurídico. En este estudio rastreamos dos de las fuentes medievales de las que Suárez se sirvió en la elaboración de su noción de un «estado de
El mundo ficcional: Fenomenología del mundo de fantasía
Authors: Mendoza-Canales Ricardo
Published: August 2020

El presente artículo se propone explorar la noción de mundo ficcional desde la filosofía de Edmund Husserl, destacando la potencialidad de la fenomenología para los campos de la estética y la teoría de la ficción. Para ello, partiré de la descripción de las estructuras sobre las que se erige la vivencia ficcional, que aquí será tratada como una vivencia de fantasía. Bajo este enfoque, el análisis muestra primero la correlación entre conciencia de fantasía y mundo de fantasía, pasando a continuación a explicitar las estructuras de cada uno de los polos de experiencia. Para Husserl, esta correlación se sustenta lógicamente en la doctrina del idealismo trascendental y en su concepción del mundo de fantasía como mundo posible.
Drift, Naturally: A Transaffective Unfolding
Authors: Kousoulas Stavros
Published: August 2020

If any individual is determined by its affects as they are catalyzed in the technicities it unfolds, then one can no longer speak of posthumanism or transhumanism but of transaffectivity. Among genetic, epigenetic, and epiphylogenetic elements, there unfolds a play of intensive material informational exchange that determines both the structural and operational affects of any entity. Hence, evolution returns to its original Latin meaning, namely from the term evolutio: to unfold. Contrary to the logic of the survival of the fittest, unfolding does not dictate in advance which forms come forth, but instead, it determines which of them are not viable. In other words, it is the condition that brings forward a new world, one that is viable through the very differentials that determine the condition, and not the other way around. In this paper I will examine how structurally coupled individuals unfold an intensive continuum where there is no natural selection prescribing any outcome, but a continuous natural drift. The affective potentials that produce and are produced in the technicities of the drifted unfolding do not need to be the best, but simply good enough. Put succinctly, evolution, or more precisely, individuation, is satisficing rather than optimizing. Love—human, machinic, everything in between—and not Darwinian struggle or opposition is what determines evolution: not an affective diminution but instead an affirmative, transaffective amplification, where any individual structurally coupled with another brings forth a world through an aberrant nuptial, not because it must but simply because it can.

Published: August 2020

The emotional component of the educational process has been stated to be an essential factor of the formation of interest of a foreign student to learn the Ukrainian language as a foreign one. As it is one of the effective ways to improve of effective studying, rationalization and optimization of teaching methodology, based on analysis of the row of theoretical, methodological and experimental investigations in branches of psychology, psycho-linguistics, intercultural communication and pedagogy of the higher school. It has been indicated, that the principle of emotionality belongs to some basic principles of personal-oriented approach to studying. The theoretical and methodological analysis of directions of emotions implementation has been conducted in the process of didactics and communication, productive ways and methods of actualization of emotional factor have been developed at classes of Ukrainian as a foreign language; cultural peculiarities of apprehension of the emotional component of the educational process by different ethnic groups have been investigated. It has been proved, that satisfaction or dissatisfaction of communicative need of an international student generates positive or negative emotions, which influence on communicative activity, educational process, and consequently, on the process of cognition as a whole. The empirical part of the investigation was conducted based on interrogation of foreign students of Higher State Educational Institution of Ukraine. It aimed to detect national features of emotions perception by representatives of different nationalities (students from India, Africa and Arabic countries). The analysis showed that such factors as students do not see their progress in learning a language, difficulties in language understanding on hearing, the great synonymous potential of Ukrainian language become reasons for negative emotions in the process of learning Ukrainian as a foreign language, i.e. disappointment, indifference, concern, fear, dispossession. The group of effective methods has been distinguished for the provision of learning emotionality: verbal, extra-linguistic and activity-role. It has been found out, that emotional stimulation belongs to effective methods of activation of communicative as well as educational activity as a whole. Methodological recommendations are distinguished, which are specific for teaching foreign students concerning the realization of the principle of emotionality in multicultural different ethnic students’ audience.

Published: August 2020

This article discusses the main tools and methods of teaching a professional foreign language. Theoretical and practical bases of the organization of the process of introduction and implementation of technologies in teaching foreign languages in higher education are considered and analyzed. The systematization of general trends taking into account domestic and foreign scientific experience is carried out. It also presents the points of view of various scientists on the relevance of studying this topic, formulated recommendations for the introduction of modern effective experience in the practice of foreign language lecturers.The actual task of education, in the trend of globalizing world processes, is teaching a professional foreign language. The development of international cooperation in the fields of education, medicine, natural, technical, and economic sciences requires the study and constant improvement of foreign languages.The existing problems of education require a comprehensive solution. This solution will be achieved using the program-target method.The weakest skill among university students was oral speech. This indicates that conversational skills are a weak point, which is confirmed during observations of classes. A survey of 500 students showed that speaking classes were rated significantly higher than classes for practicing other skills.Thus the aim of the article is a theoretical analysis of scientific approaches of researchers to the problem of teaching a professional foreign language for specialists in various fields.
A Multilevel Investigation of Fall Prevention Behavior Among Nursing Staff of South Korean Geriatric Hospitals
Authors: Park Yunhee , Yun Hyun-Jung
Published: August 2020

BACKGROUND: There is lack of empirical evidence on whether organizational variables affect the fall prevention behavior of nursing staff working at Korean geriatric hospital. Aim This study aimed to investigate individual and organizational characteristics associated with the fall prevention behavior of nurses and nurse aides.

METHODS: A descriptive cross-sectional research design was used. A convenient sample of 426 clinical nurses and nurse aides from 8 geriatric hospitals in South Korea was recruited between October and November 2019. Hierarchical regression analysis was used to estimate the effects of individual- and organization-level predictors.

RESULTS: The result indicated that fall prevention self-efficacy (β=0.41, p<.001) was a significant individual-level predictor. At the organizational level, Nurse to nurse aides ratio (β=.21, p=.005) and number of patients per physical therapist (β=-.28, p=.014) were significant predictors. Furthermore, there was a significant change of R2 (p=.034) when organizational variables were included in the regression model.

CONCLUSION: To increase fall prevention behavior of nurse and nurse aides, administrators in geriatric hospital should recognize the importance of staffing, such as nurse and physical therapist. Further studies are proposed to investigate the empirical evidence about the association between organizational variables and patient outcomes.
Time-Varying Parameter Population Health Models and the Health Effects of Social Services vs. Health Care Spending: An Application to Canada
Authors: Faroque Akhter
Published: August 2020

A recent strand of the health literature claims that, for a healthier population, governments in high-income countries such as Canada should shift expenditure from health care to the provision of social services. Authors in this literature make this recommendation based on the finding that in standard static constant-parameter health models, the ratio of social services to health care spending is systematically associated with higher life expectancy and lower mortality across the OECD countries. We evaluate the robustness of this important claim to (i) likely time-variation in the model parameters (ii) delayed effects of health determinants and (iii) to disaggregation of health care spending into its major components.

Methods: We conduct a longitudinal study of the comparative empirical performances of four time-varying parameter, dynamic and disaggregated health-indicator models relative to the benchmark models typically estimated in the literature, using a Canadian national dataset.

Results: We find evidence that spending on social services may indeed increase life expectancy and lower mortality more than spending on health care; but this finding emerges only in dynamic models that allow for time variation in the coefficients. Disaggregation generally shows that hospital care lowers mortality by more than all other categories of spending, including social services.
Contextualizing Anti-Immigrant Attitudes of East Europeans
Authors: Bandelj Nina , Gibson Christopher W.
Published: August 2020

This paper article examines attitudes toward immigrants by analyzing data from the 2010 and 2016 waves of the EBRD’s Life in Transition Survey among respondents from 16 East European countries. Logistic regressions with clustered standard errors and country fixed effects show significantly higher anti-immigrant sentiments after the 2015 immigration pressures on the European Union borders compared with attitudes in 2010. Almost two thirds of the respondents agreed in 2016 that immigrants represented a burden on the state social services, even when the actual immigrant population in these countries was quite small. In addition, East Europeans expressed greater negative sentiments when the issue of immigration was framed as an economic problem—a burden on state social services—than as a cultural problem—having immigrants as neighbors. On the whole, these results point to the importance of contextualizing anti-immigrant attitudes and understanding the effect of external events and the framing of immigration-related survey questions.
Prezentacja aplikacji mobilnej do oceny narażenia na promieniowanie UV w otoczeniu spawania łukowego

Published: August 2020

Promieniowanie nadfioletowe (bezpośrednie i odbite) może stanowić zagrożenie dla zdrowia osób postronnych pracujących lub przebywających w pobliżu miejsc, w których wykonuje się spawanie łukowe. Napromienienie promieniowaniem UV (iloczyn natężenia napromienienia i czasu ekspozycji) skóry czy oczu człowieka przebywającego w pomieszczeniu spawania nawet w obszarach oddalonych od łuku lub osłoniętych przesłonami spawalniczymi może przekraczać wartości maksymalnych dopuszczalnych ekspozycji (MDE). Stąd istotne jest takie zaprojektowanie stanowisk pracy znajdujących się w pomieszczeniu, w którym wykonuje się spawanie, aby inni pracownicy nie byli narażeni na nadmierne promieniowanie UV. Opracowana aplikacja mobilna może w tym pomóc. Umożliwia ona oszacowanie wartości natężenia napromienienia oraz dopuszczalnego czasu ekspozycji pracownika przebywającego w dowolnym miejscu pomieszczenia, a także zamodelowanie ustawienia osłon spawalniczych tak, aby ograniczyć ryzyko zawodowe do małego. Warunkiem jest posiadanie danych pomiarowych natężenia napromienienia przy danym procesie spawalniczym i ich wpisanie do obliczeń w aplikacji. Jeśli takich danych użytkownik nie posiada, to może zakupić opracowaną w CIOP-PIB bazę danych pomiarowych dla różnych procesów spawania i wybrać wynik pomiaru dla danego procesu spawania.
Opracowana aplikacja (bez bazy danych pomiarowych) jest dostępna bezpłatnie na stronie CIOP-PIB i może być istotnym narzędziem monitorowania zagrożeń lub ich źródeł oraz komunikowania o nich.
Rheology of Structured Oil Emulsion
Authors: Isfandiyar Kelbaliyev Gudret , Babir Tagiyev Dilgam , Rizvan Manafov Manaf
Published: August 2020

This study is devoted to the rheology of oil emulsions, accompanied by both the formation and destruction of the structure. The presence of particles of a dispersed phase in an oil emulsion, including asphaltenes and resins, determines the formation of coagulation structures as a result of interaction and collision of particles. In this regard, to study the formation of coagulation structures, analytical solutions to the mass transfer equations are proposed, based on which the coalescence and fragmentation frequencies of the droplets are determined. Models and analytical solutions of the equation for the thinning of an interfacial film between droplets with their coalescence in the volume of an oil emulsion are proposed taking into account the Marangoni effect and the effect of asphaltene content. The thickness of the adsorbed layer on the droplet surface was estimated. Many empirical and semiempirical formulas have been proposed for determining the dependence of viscosity on the content of water and asphalt-resinous substances in oil. Based on the solution of the Fokker-Planck equation, the evolution of the distribution function of droplets in time and size in an oil emulsion is studied.
Region of Interest Localization Methods for Publicly Available Palmprint Databases
Authors: Liang Xu , Fan Dandan , Li Zhaoqun , Zhang David
Published: August 2020

So far, there exist many publicly available palmprint databases. However, not all of them have provided the corresponding region of interest (ROI) images. If everyone uses their own extracted ROI images for performance testing, the final accuracy is not strictly comparable. Since ROI localization is the critical stage of palmprint recognition. The location precision has a significant impact on the final recognition accuracy, especially in unconstrained scenarios. This problem has limited the applications of palmprint recognition. However, many currently published surveys only focus on feature extraction and classification methods. Throughout these years, many new ROI localization methods have been proposed. In this chapter, we will group the existing ROI localization methods into different categories, analyze their basic ideas, reproduce some of the codes, make comparisons of their performances, and provide further directions. We hope this could be a useful reference for further research.

Published: August 2020

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has necessitated the alteration of the organization of entire hospitals to try to prevent them from becoming epidemiological clusters. The adopted diagnostic tools lack sensitivity or specificity. Objectives: The aim of the study was to create an easy-to-get risk score (Ri.S.I.Co., risk score for infection with the new coronavirus) developed on the field to stratify patients admitted to hospitals according to their risk of COVID-19 infection. Methods: In this prospective study, we included all patients who were consecutively admitted to the suspected COVID-19 department of the Bufalini Hospital, Cesena (Italy). All clinical, radiological, and laboratory predictors were included in the multivariate logistic regression model to create a risk model. A simplified model was internally and externally validated, and two score thresholds for stratifying the probability of COVID-19 infection were introduced. Results: From 11th March to 5th April 2020, 200 patients were consecutively admitted. A Ri.S.I.Co lower than 2 showed a higher sensitivity than SARS-Cov-2 nucleic acid detection (96.2% vs. 65.4%; P < 0.001). The presence of ground-glass pattern on the lung-CT scan had a lower sensitivity than a Ri.S.I.Co lower than 2 (88.5% vs. 96.2%; P < 0.001) and a lower specificity than a Ri.S.I.Co higher than 6 (75.0% vs. 96.9%; P < 0.001). Conclusions: We believe that the Ri.S.I.Co could allow to stratify admitted patients according to their risk, preventing hospitals from becoming the main COVID-19 carriers themselves. Furthermore, it could guide clinicians in starting therapies early in severe-onset cases with a high probability of COVID-19, before molecular SARS-CoV-2 infection is confirmed.

The Corda river is the main source of fresh water for recreation, leisure, supply and irrigation to the municipality of Barra do Corda - MA. The objective of the present study was to evaluate the physicochemical parameters of Corda river’s water using the methodology described by the American Public Health Association. The water samples were collected in the seasonal period spanning between February and September of the year of 2018. The parameters which were analyzed during the study were pH, conductivity, turbidity, total dissolved solids and salinity, besides concentrations of nitrite, nitrate, and total phosphorus. Three principal components were identified during the PC Analysis. Those components explain more than 74% of the total variance observed during the rainy and dry season. Axis 1and 2 included variables which were related to quality of water and could be affected by the change in seasons. The results indicated that pH (7.11), P (2,82 mg L-1), NO3- (3,23 mg L-1), turbidity (35.82 NTU) and conductivity (35.83 µS/cm) parameters were most affected by changing from rainy to dry season.

Published: August 2020

The mining activity generates several negative and positive impacts. Among the negatives impacts, it is find the reduced air quality, noise generation and increased population flow, which directly affect the health quality of the local population and the enterprise workers. Thus, the aim of this work was to perform an analysis of documents as Environmental Impact Study (EIS) and Terms of Reference (TR) regarding the approach of health aspects in mining activities licensed by the Brazilian federal environmental agency, proposing a methodology for its evaluation. The methodology consisted of a qualitative and quantitative analysis of health aspects according to the matrix already used in another study. It was proposed to insert weights for attributes analysis culminating in a scale of approach to health aspects: low, medium and high. Thus, limitations were found regarding the availability of studies and TRs in the environmental agency system. Regarding the EIS, most aspects of health had a medium approach, the diagnostic stage was highlighted as the most complete and the monitoring and accompaniment stage were detected as presenting the lowest approach. The greatest weaknesses was the identification of specialists responsible for the health approach, the lack of estimates of investments in the sector.

The Generalized Additive Models for Location, Scale, and Shape (GAMLSS) are a recent class of models that further flexibilitythe distribution of the response variable. The regression analysis has been used to model biological phenomena, and its variousmodalities have met the need for its use with precision. However, there are situations in which the adjustment of models with moreflexible assumptions in the specification of the distribution of the response variable becomes indispensable, thus justifying the useof GAMLSS. The study of plant growth curves has full application in agricultural research; thus, it is crucial to know the habits ofgrowth and development of forest species is crucial for reforestation programs and in the most diverse researches. The study aimedto model the growth of Eucalyptus through the adjusting of Generalized Additive Models for Location, Scale, and Shape, in orderto promote improvements on crop productivity. Considering all parameters of the independent variable (time) under GAMLSSclass modeling, the distribution model ST3 presented better results.

This study describes the application of peanut shells, a biodegradable agroindustrial residue as a biosorbent, in the 17α-ethinylestradiol (EE2) removal in water matrices. An analytical method was developed and validated from the high-performance liquid chromatographic technique with fluorescence detection (HPLC-FLD) in a λEx= 230 nm and λEm= 310 nm in the determination of EE2. The evaluated parameters were: selectivity, linearity (R2 = 0.9984 and R = 0.9992), precision (Variation coefficient = 2.90% and 2.95% for the first and second analyst, respectively), accuracy (recovery rate = 100.2 – 110.4%), detection limit (3.4 – 5.0 μg L-1), quantification limit (10.0 – 11.3 μg L-1) and robustness (recovery rate = 98.7 – 115.5%). The chromatographic analysis conditions were: mobile phase (water 2:3 acetonitrile), mobile phase flow (0.5 mL min-1), injection volume (10 µL), column temperature (45ºC) and race time (10 min). An experiment planning (Box-Behnken Model) was carried out for the investigation and verification of the adsorptive capacity of the peanut shells, of which 3 parameters were evaluated (stirring rate, pH and adsorbent mass) on 3 levels. Optimum experimental condition (2 g of adsorbent, pH = 6 and stirring at 500 rpm) with a removal rate of 90% in 24 hours of the process.

Published: August 2020

This work intends to analyze the use of the qualitative method in studies related to solid waste management. A systematic literature review of the articles published between 2014 and 2019 was made in the Scielo databases (Scientific Electronic Library Online), in the CAPES Journal Portal and Web Of Science. In addition to searching for reference journals in the area of waste (Waste Management and Waste Management and Research) through the descriptors “Qualitative Research” and “Solid Waste”; “Interview”, “Solid Waste” and “Perception” (Interviews, Solid Waste and Perception) and 598 articles were found, and after applying the selection criteria the universe was reduced to a total of 42 publications. The selected articles were analyzed and categorized according to the most relevant aspects such as work objectives, study sample and main results. Qualitative research has been found to be a viable tool and can be employed on a large scale in waste-related studies. It was also found that many studies that use the term “qualitative research” do not have the necessary methodological rigor to be named. It was found that qualitative research is adequate to answer questions in the field of waste studies such as the relationship between waste and public health problems, difficulties in selective collection and other management / treatment actions, environmental impacts, irregular waste disposal and problems in the management of special waste

Background: Pathologic complete response (pCR) is a common efficacy endpoint in neoadjuvant therapy trials for triple-negative breast cancer (TNBC). Previous studies have shown that pCR is strongly associated with improved long-term survival outcomes, including event-free survival (EFS) and overall survival (OS). However, the trial-level associations between treatment effect on pCR and long-term survival outcomes are not well established. This study sought to evaluate these associations by incorporating more recent clinical trials in TNBC. Methods: A literature review identified published randomized controlled trials (RCTs) of neoadjuvant therapy for TNBC that reported results for both pCR and EFS/OS. Meta-regression models were performed to evaluate the association of treatment effect on pCR and EFS/OS. Sensitivity analyses were conducted to assess the impact of divergent study designs. Results: Ten comparisons from 8 RCTs (N=2,478 patients) were identified from the literature review. The log (odds ratio) of pCR was a significant predictor of the log (hazard ratio) of EFS (P=.003), with a coefficient of determination of 0.68 (95% CI, 0.41–0.95). There was a weaker association between pCR and OS (P=.18), with a coefficient of determination of 0.24 (95% CI, 0.01–0.77). Consistent results were found in the exploratory analysis and sensitivity analyses. Conclusions: This is the first study that has shown a trial-level association between pCR and survival outcomes in TNBC. By incorporating the most up-to-date RCTs, this study showed a significant trial-level association between pCR and EFS. A positive association between pCR and OS was also recorded.

Background: There is conflicting evidence regarding the role of chemotherapy for high-grade soft tissue sarcoma (STS) in adults. We sought to characterize patterns of chemotherapy use, including multiagent and neoadjuvant chemotherapy, in the United States. Patients and Methods: Using the National Cancer Database, we identified 19,969 adult patients who underwent surgical resection for primary high-grade STS from 2004 to 2016. Using logistic regression, we examined factors associated with overall, multiagent, and neoadjuvant chemotherapy use. Results: Chemotherapy was administered to 22% (n=4,377) of the study population. Among patients treated using chemotherapy, 85% received multiagent treatment and 47% received neoadjuvant treatment. On multivariate analysis, factors associated with chemotherapy use included tumor size, depth, histology, and primary site; receipt of radiation treatment; younger age; higher patient income; and academic treatment facility. Factors associated with multiagent chemotherapy use included tumor histology, tumor primary site, and younger age. Factors associated with neoadjuvant chemotherapy use included tumor size, depth, margin status, and primary site; receipt of radiation treatment; higher patient income; academic treatment facility type; and distance to treatment facility. Treatment at a high-volume facility was the only factor associated with overall, multiagent, and neoadjuvant chemotherapy use. No significant temporal trend was seen in overall, multiagent, or neoadjuvant chemotherapy use. Conclusions: Overall chemotherapy use was low (22%). The variability in chemotherapy use was driven by clinical, patient, demographic, and facility factors. Among patients treated with chemotherapy, the use of multiagent chemotherapy was high (85%), and nearly half received neoadjuvant therapy. There was a discrepancy in the use of chemotherapy—including neoadjuvant and multiagent chemotherapy—between high- and low-volume treatment centers.

The estimated 5-year survival rate for patients with stage IV uterine leiomyosarcoma is 29%, with a median survival of <1 year. This report describes a patient with stage IVB leiomyosarcoma who experienced stable disease for 15 months on pembrolizumab. A woman aged 62 years, gravida 2 para 2, with postmenopausal bleeding and a necrotic uterine fibroid underwent a dilation and curettage and was diagnosed with uterine leiomyosarcoma. CT imaging showed pulmonary and bony metastasis. She underwent surgical staging with biopsy-proved stage IVB disease. A mixed partial response was noted using first- and second-line chemotherapy. Molecular tumor profiling confirmed PD-L1 expression. The patient was started on pembrolizumab, and at the time of writing she is status post 23 cycles with stable disease. Pembrolizumab was well tolerated and aided prolonged disease stabilization.
On the Ends of the Network as a Zone of Friction (And Extraction)
Authors: Basu Sudipto
Published: August 2020

In a world-order where planetary computational networks have restructured nearly all spheres of existence, what is not already networked lies in wait merely as standing-reserve. Today, it seems as if the network and the world are naturally interoperable. Thinking through Harun Farocki’s work on operational images, I however locate a zone of friction or incommensurability between the network and the world. Revisiting Norbert Wiener’s anti-aircraft predictor – a founding episode in the history of cybernetics – I show how this gap was bridged by a logic of (en)closures that reduced the living human form and the world to narrow operational ends; banishing the openness and indeterminacy of both life and nature into undesirable contingency. However, cybernetics’ relentless expansion into a universal episteme and planetary infrastructure since the Cold war necessarily floods the network with contingency; which it wards off by feeding on a disavowed living labor. I argue that this living labor is an uneasy reconciliation of mechanism and vitalism, which we may call habits. Drawing on the Marxian notion of general intellect, I posit how habits are key to generating network surplus value, and to cybernetic expansionism. Habits shape, prepare the outside for its subsumption into the network. Yet they are not given the status of productive activity, and consequently disavowed and vaporized by networks. I propose that this living labor be given a specific name – interfacing – and, following Georges Bataille’s critique of political economy, speculate on the reasons for its disavowal. Drawing on Bataille’s idea of the general in ‘general economy’ (that which is opposed to utilitarian or operational ends) and Hito Steyerl’s How Not to Be Seen, I try to imagine what an interface contiguous with the general intellect might be.
Revisiting Cognitive Mapping
Authors: İşcen Özgün Eylül
Published: August 2020

The increasingly complex, algorithmically mediated operations of global capital have only deepened the gap between the social order as a whole and its lived experience. Yet, Fredric Jameson’s notion of cognitive mapping, attentive to the conflicting tendencies of capitalist operations, is still helpful for addressing the local instantiations of capital’s expanding frontiers of extraction. I am interested in tracing the historicity of those operations as well as the totality they are actively part of in the present from the vantage point of the Middle East, especially along with the entangled trajectories of oil, finance, and militarism. To this end, I examine countervisual practices in the realm of media arts that contest the aesthetic regime through which the state-capital nexus attempts to legitimize its imperial logic and violence. My reconfiguration of cognitive mapping as countervisuality in Nicholas Mirzoeff’s terms demonstrates that there is no privileged position or method of cognitive mapping, which ultimately corresponds to an active negotiation of urban space across the Global North/ South divide.
Intuition Machines
Authors: Kronman Linda
Published: August 2020

The urgency of environmental, security, economic and political crises in the early twenty-first century has propelled the use of machine vision to aid human decision-making. These developments have led to strategies in which functions of human intuitive processing have been externalized to ‘vision machines’ in the hope of optimized and objective insights. I argue that we should approach these replacements of human nonconscious functions as ‘intuition machines.’ I apply this approach through a close reading of artworks which expose the hid- den labour required to train a machine. These artworks demonstrate how human agency shapes the ways that machines perceive the world and reveal how values and biases are hardcoded into nonconscious cognitive machine vision systems. Thus, my analysis suggests that decisions made by such systems cannot be considered fundamentally objective or true. Nevertheless, artworks also exemplify how externalized intuitive processing can still be helpful as long as we refrain from blindly taking the results as a go-signal to take immediate action.
Tactical Archives Cartography

Published: August 2020

This article narrates our work through archive and cartography to discuss a body of research that runs throughout our lives - as producers, developers, non-artists, artists, archivists, researchers. We have been engaging in networks that develop the internet, tactical media, and free knowledge since the beginning of 2000 in Brazil, in a series of festivals, projects, platforms and other forms of gatherings. A lot of this history is lost in databases and we have been putting our efforts together to bring this digital and material archive together, republishing, editing and re activating it. At the same time, it is inevitable that we bring our own perspective to building the archive, what we identify as a feminist perspective, a weaving of histories (reinventeceduras) and modes of production that are also a “maintenance” of technical infrastructure as a practice of care, connected to the reproduction of our own lives. Cartography is a concept and tool that allows for the gathering of the polyphony of the voices engaged, a cartography that is not total, opening up for collective analysis and for the intervention in the present and future.
Translation (Dis)Junctions, or Postsocialist Connectivity
Authors: Glushneva Iuliia
Published: August 2020

This article focuses on language transfer as a fundamental factor in the construction of postsocialist network technosociality. By looking at the early days of the Internet in Russia and the current landscape of the Russian-language cyberspace, it demonstrates that excessive translation activity becomes an essential tool of postsocialist integration with global network economies and cultures. At the center of this activity is voice-over, a form of “half dubbing” and a dominant screen translation practice on the Runet. While this article explores the histories and defining features of performance and labor of this practice, it argues that the voice-over translation is a mode of connectivity that exposes the centrality of asynchrony and distortion to postsocialist networking as well as to the network as such.
