Incorporation of epoxidized oleic acid plasticizer into poly(vinylidene fluoride)
Authors: Zulkifli Wan Nur Fatihah Wan Muhammad , Hazmi Ahmad Syafiq Ahmad , Idris Zainab
Published: May 2022

Poly(vinylidene fluoride) (PVDF) polymers are utilized in the processing of foods and beverages due to their highly stable nature. This makes plasticizer selection crucial. The incorporation of epoxidized oleic acid (EOA) as a bio-plasticizer into PVDF in the solution blending process was investigated. Scanning electron microscopy analysis showed the toughening effects in the structure of the blends. The degree of crystallinity was found to decrease with an increase in the EOA ratio. The melting temperature slightly decreased with the addition of EOA. A reduction was observed in the glass transition temperature (Tg), which was the effect of the plasticizer. Bio-plasticized PVDF exhibited increased thermal resistance with higher char formation. The scanning electron fractograph showed that EOA disrupted the PVDF crystallinity with a rise in amorphicity. Crystal formation was found to be in one dimension and dependent on the bio-plasticizer content. Hence, EOA has an excellent potential as a renewable resource to substitute for conventional petroleum-based plasticizers.

Published: May 2022

Significance Statement

The evidence from individual studies to support the maturational pattern of GFR in healthy, term-born neonates is inconclusive. This paper describes GFR reference values in the first month of life using an individual participant data meta-analysis of reported measured GFR (mGFR) data using data from 881 neonates. GFR doubled in the first 5 days after birth, from 19.6 to 40.6 ml/min per 1.73 m2, and then more gradually increased to 59.4 ml/min per 1.73 m2 by 4 weeks of age. GFR was best estimated by 0.31×height (cm)/serum creatinine (mg/dl). These mGFR reference values and more accurate GFR estimations can help to identify altered GFR in term-born neonates; however, further validation of the eGFR equation is needed.

Background

The evidence from individual studies to support the maturational pattern of GFR in healthy, term-born neonates is inconclusive. We performed an individual participant data (IPD) meta-analysis of reported measured GFR (mGFR) data, aiming to establish neonatal GFR reference values. Furthermore, we aimed to optimize neonatal creatinine-based GFR estimations.

Methods

We identified studies reporting mGFR measured by exogenous markers or creatinine clearance (CrCL) in healthy, term-born neonates. The relationship between postnatal age and clearance was investigated using cubic splines with generalized additive linear mixed models. From our reference values, we estimated an updated coefficient for the Schwartz equation (eGFR [ml/min per 1.73 m2]=(k×height [cm])/serum creatinine [mg/dl]).

Results

Forty-eight out of 1521 screened articles reported mGFR in healthy, term-born neonates, and 978 mGFR values from 881 neonates were analyzed. IPD were available for 367 neonates, and the other 514 neonates were represented by 41 aggregated data points as means/medians per group. GFR doubled in the first 5 days after birth, from 19.6 (95% CI, 14.7 to 24.6) to 40.6 (95% CI, 36.7 to 44.5) ml/min per 1.73 m2, and then increased more gradually to 59.4 (95% CI, 45.9 to 72.9) ml/min per 1.73 m2 by 4 weeks of age. A coefficient of 0.31 to estimate GFR best fitted the data.

Conclusions

These reference values for healthy, term-born neonates show a biphasic increase in GFR, with the largest increase between days 1 and 5. Together with the re-examined Schwartz equation, this can help identify altered GFR in term-born neonates. To enable widespread implementation of our proposed eGFR equation, validation in a large cohort of neonates is required.
Genetic Criticism and Analysis of Interface Design. A Case Study
Authors: Armaselu Florentina
Published: May 2022

The paper proposes a methodology that combines theoretical and practical aspects from human-computer interaction (HCI) and genetic criticism to trace and analyse prototype evolution. A case study illustrates this type of enquiry by examining the iterations and the dynamics of change in the design and development of the Transviewer, an interface for digital editions. The initial assumption is that such an analysis can inform existing models in interface design and possibly provide new ground for discussion in humanistic HCI. For instance by fostering broader reflections on software production as a technological and cultural artefact and the gradual shaping of the principles and metaphors underlying the construction of a certain type of knowledge, argument, or interpretation through an interface. Cet article propose une méthodologie qui combine les aspects théoriques et pratiques de l’interaction homme-machine (IHM) et la critique génétique afin de repérer et analyser l’évolution de prototypes. Une étude de cas illustre ce type d’enquête en examinant les itérations et les dynamiques du changement dans la conception et le développement de Transviewer, une interface pour des éditions numériques. La supposition initiale est qu’une telle analyse peut offrir des renseignements sur les modèles existants de la conception d’interface et peut potentiellement fournir de nouvelles informations à la discussion autour de l’IHM humaniste. Par exemple, cela peut faciliter de meilleures réflexions plus élargies sur la production de logiciels comme artefact technologique et culturel, ainsi que sur la formation progressive des principes et métaphores qui sont à la base de la construction d’un certain type de connaissance, d’argument, ou d’interprétation à travers une interface.
An Overview of Tobacco Policies in Kansas Unified School Districts
Authors: Hazard Riley , DeVader Shannon , Lu Kelsey , Ablah Elizabeth
Published: May 2022

Introduction. In 2019, 25.8% of Kansas high school youth reported using any form of tobacco product. Schools can prevent and reduce youth tobacco use by adopting comprehensive tobacco policies, which include all tobacco products, on school grounds and at school-sponsored, off-campus events, for all individuals at all times, and integrate cessation services for students who violate the tobacco policy. The purpose of this study was to determine the prevalence of comprehensive tobacco policies in unified school districts (USD) across Kansas to determine how many schools have adopted such policies.

Methods. All 286 USDs in Kansas were eligible to participate in this study; this includes elementary, middle, and high schools. Participating schools were asked to upload their policies to a website developed by Kansas Department of Health and Environment (KDHE). Frequencies and percentages were computed to identify the type of tobacco products prohibited, the locations where tobacco use is prohibited, who is prohibited from using tobacco, when tobacco is prohibited, and consequences of students’ violation of tobacco policy.

Results. Several USD policies meet some of these recommendations; however, 97.9% (n = 280) do not. In other words, 2.1% of USD policies (n = 6) are comprehensive in Kansas.

Conclusions. Nearly all USDs in Kansas have an opportunity to strengthen their tobacco policies. Relatively simple edits can be made to prohibit all tobacco products, prohibit use on school grounds and at school-sponsored, off-campus events, ensure these policies apply to everyone, at all times, and integrate cessation resources for students who violate the tobacco policy.
Comparison of the frequency of bacteriuria in diabetic and non-diabetic patients without symptoms of urinary tract infection
Authors: Çalica Utku Aylin
Published: May 2022

Introduction: Urinary tract infections (UTIs) are the most common infections among either community or hospital-acquired infections. UTIs are common in diabetes mellitus, with glycosuria and neurogenic bladder being the predisposing factors.
Methods: This was a retrospective observational study. The study population consisted of 100 diabetic and 40 non-diabetic patients. The rates of bacteriuria and pyuria were investigated in diabetic and non-diabetic patients who had been hospitalized and who did not have any complaints of UTI. Urine samples of patients were collected and each sample was tested through microscopy and culture. Furthermore, the urine samples were inoculated on blood agar and eosin methylene blue agar medium and incubated for 18–24 h at 37°C. Diabetic patients were evaluated to obtain data on age, gender, duration and type of diabetes, body mass index, retinopathy, nephropathy, glycated hemoglobin (HbA1c) level, and fasting plasma glucose (FPG) level.
Results: A higher rate of bacteriuria was detected in diabetic patients (21%) than in non-diabetic patients (5%) (p = 0.02). Infections were detected more frequently in patients with high HbA1c level (p = 0.001), those in the advanced age group (p = 0.014), and those with nephropathy (p < 0.01).
Conclusion: Asymptomatic bacteriuria was more prevalent in diabetic than in non-diabetic patients, with poor glycemic control, age, and nephropathy being significant risk factors. Escherichia coli is the most common organism that causes bacteriuria in diabetic patients.

Authors: Łomozik Mirosław
Published: May 2022

The introduction contains information (found in available reference publications) concerning the weldability of steel S1300QL. The introduction also presents general information concerning the effect of the microstructure and the chemical composition of filler metals used in the welding of high-strength steels on the mechanical properties of weld deposit. The subject of simulation tests (discussed in the article) was structural steel S1300QL having a yield point of more than 900 MPa S1300QL. Simulations involved both single (Tmax = 1250°C) and double welding thermal cycles (Tmax = 1250°C + 600°C, Tmax = 1250°C + 760°C and Tmax = 1250°C + 900°C) as well as cooling times t8/5 = 3 s, 5 s and 10 s. Specimens with simulated HAZ areas were subjected to impact strength tests performed at a temperature of -40°C and +20°C, Vickers hardness tests (HV10) and microscopic metallographic tests involving the use of light microscopy. The test results are presented in related diagrams and photographs. The final part of the article contains a discussion concerning test results and concluding remarks. The tests revealed that, in terms of the test steel, the number of repetitions of thermal cycles having pre-set parameters did not explicitly translated into changes of impact energy values concerning the simulated HAZ areas. The tests also revealed that recommended thermal cycles making it possible to obtain the required combination of the high toughness and hardness of the simulated HAZ area of steel S1300QL (similar to that of the base material) were double thermal cycles of maximum temperature Tmax1 = 1250°C + Tmax2 = 600°C and Tmax1 = 1250°C + Tmax2 = 900°C combined with cooling times t8/5 = 5 s and 10 s and all numbers of repeated thermal cycles.

Authors: Sawicki Antoni
Published: May 2022

The article presents universal mathematical static current-voltage characteristics- based models of electric arc and indicates primary issues concerned with arc diagnostics related to the determination of the above-named models. Particular attention was paid to the experimental determination of AC-powered arc voltage. Diagnostics-related purposes involved the use of bridge systems with one or two sources of current. Computer-aided simulations involving sinusoidal and trapezoidal current-based excitations made it possible to demonstrate the possibility of obtaining minimum values of bridge unbalance voltage. Such a condition indicated the proper determination of AC-powered arc ignition voltage.
Theory of Information and Computer Support for Forensic Expert Activities as a New Private Theory of Forensic Expertology
Authors: Rossinskaya E. R.
Published: May 2022

From the stand point of global digitalization, the article substantiates the creation of a new private theory of forensic expertology — the theory of information and computer support of forensic expert activity. The author outlines the main stages of the genesis the processes of automation and informatization for forensic research. At the first stage, in the mid-60s, many works related to the use of cybernetics in the automation of certain types of forensic examinations appeared in the forensic literature. The second stage occurred at the end of the 80s — 90s of the XX century, when the integration of new information technologies, mainly of a technological nature, began to develop in five main directions, thanks to the development of computer technology. In the early 2000s, the third stage of informatization and computerization of forensic expertise began. The processes of digitalization in forensic activity gave a new impetus to the development of not only the areas of information and computer support, which continued to improve, but also the emergence of research in many kinds (types) forensic examinations of new objects expert research — digital footprints. The author states that there was no theoretical basis for their forensic expert research in forensic expertology. Therefore, a new private theory (teaching) of forensic expertology has been developed — the theory of digitalization for forensic expert activity. The subject of this theory and its objects, the place of the new theory in forensic expertology are described. It has been proved that the theory of digitalization for forensic activity, due to the increasingly global nature of digitalization, can be attributed to several private theories, the provisions of which equally apply both to the process of expert research as a whole and to expert research of certain types of expertise. The modern theory of digitalization of forensic activities includes two areas: a system of information and computer support for forensic activities and forensic research of digital footprints.

Published: May 2022

Objective. To study the sanitary and parasitological state of environmental objects in Astrakhan region.

Materials and methods. A total of 45,475 samples taken from various environmental objects in Astrakhan region were analyzed. The number of unsatisfactory samples was 1.1 % (484 samples).

Results. For the period from 2015 to 2019, there were studied the following samples: soil 12.5 % (5518 samples), water 6.9 % (3026 samples) and flushes from solid household surfaces 80.6 % (35501 samples).

The percentage of washout samples from hard surfaces was 80.6 % (35,501 samples). The number of unsatisfactory samples was 0.003 % (1 sample). In this sample, teniid oncospheres were detected in 2019. The share of water samples was 6.9 % (3026 samples). Positive findings in the form of helminth eggs and larvae, as well as cysts of pathogenic intestinal protozoa were 3.1 % (93 samples). In addition to samples taken from environmental objects, samples of food raw materials and food products were studied 3.1 % (1430 samples). The number of unsatisfactory samples was 4.6 % (66 samples). In these samples there were found: larvae of Strongyloides stercoralis 84.8 % (56 samples), eggs and metacercariae of Opisthorchis felineus 4.5 % (3 samples), cysts of Entamoeba histolytica, larvae of Strongyloides stercoralis + Ascaris lumbricoides 3.0 % for each (2 samples for each), eggs of Ascaris lumbricoides and Enterobius vermicularis 1.5 % (1 sample) and larvae of Strongyloides stercoralis + Toxocara Canis 1.5 % (1 sample).

Conclusions. The presence of mobile strongylid larvae and toxocar eggs in the soil indicates contamination of this object with the feces of invaded animals, and the presence of ascariid eggs, opisthorchis, dwarf tapeworm, teniid oncospheres and dysentery amoeba cysts in the soil indicates contamination with the feces of invaded people. The presence of eggs and larvae of helminths characteristic of animals and humans in samples taken from open reservoirs indicates, first of all, the contamination of these objects with the feces of infected people and/or animals, as well as the presumed version of water contamination with sewage. The presence of Toxocara eggs and strongylid larvae on the samples of fruit and vegetable products indicates soil contamination with the feces of invasive animals. The presence of ascarid eggs on the food indicates contamination of the soil with the feces of infested people.

Analysis of phagocytic activity of peripheral blood and exudate leukocytes in patients with facial phlegmon
Authors: Godovalov A. P. , Shtraube G. I. , Boev I. A.
Published: May 2022

Objective. To assess the phagocytic activity of peripheral blood and exudate leukocytes in patients with facial phlegmon. Currently, relatively little attention is paid to assessing the functional activity of peripheral blood and exudate leukocytes in facial phlegmon, the incidence of which is characterized by an increase in the number of cases and, especially, among patients with comorbid pathology.

Materials and methods. To study the phagocytic activity of leukocytes using a method based on the assessment of the absorption of formalinized sheep erythrocytes by neutrophils and monocytes, the samples of peripheral blood and exudate were obtained from 18 patients diagnosed facial phlegmon. Blood leukocytes obtained from 29 healthy donors were used as a comparison group.

Results. It was shown that for patients with phlegmon of the face, an increase in the phagocytic activity of peripheral blood leukocytes is characteristic. There was observed a redistribution of leukocytes according to the number of absorbed objects towards an increase in actively phagocytizing cells 4438 721 per 1 l (in the comparison group 297 67 per 1 l; p 0.05). However, after migration to the foci of the pathological process, leukocytes lost their phagocytic activity and the number of phagocytic cells decreased to 35.0 8.3 % (for peripheral blood leukocytes of the same patients 64.3 5.4 %; p 0.05). Changes in the phagocytic activity of exudate leukocytes affected both neutrophils and monocytes.

Conclusions. Thus, in patients with phlegmon of the face, changes in the phagocytic activity of blood leukocytes are probably associated with the indirect influence of cytokines, and in the focus of inflammation, leukocytes come under pressure from microorganisms. In such a situation, it is necessary to select an effective immunotropic therapy.

Estimating Explosion Yields Using Moment Tensor Solutions and Seismic Moment
Authors: Pasyanos Michael E.
Published: May 2022

Seismic moment, a measurable and well-understood quantity of seismic sources, is used to estimate the yield of explosions. Application of such a method in the past, as in the manner of mb-derived yields, has been complicated by the effect of variations in the explosion working point, depth, and secondary source effects (such as spalling and tectonic release) on the observed moment. We start using the full (six-element) moment tensor solution, which can capture the relevant source physics and, at least in theory, better isolate the primary explosion source. The moment-to-yield ratio is then estimated using an explosion source model which, provided with emplacement conditions, can relate the two parameters. We discuss the major sources of uncertainty associated with the method, and calibrate it with chemical and nuclear explosions at the Nevada National Security Site. We then apply the method to published moment tensor solutions for the six declared North Korean nuclear explosions that occurred between 2006 and 2017. The results are mostly consistent with other yield estimates made using a variety of high-frequency methods. This technique is a new approach to estimating explosive yield and simple to implement, as much of the complexity is captured by the source models.

Improvement of Micropropagation through Combination of Plant Growth Regulators in Indonesian Sorghum Hybrid Cultivar
Authors: Ningtiyas Wulan Nursyiam
Published: May 2022

Sorghum is a tropical grass used for various purposes including food, animal feed, and biofuels source, but its in vitro propagation still found an obstacle due to tissue browning. This study aims to propagate and regenerate callus in the Indonesian sorghum hybrid, named Numbu cultivar from seed and meristematic leaf whorl explants. The combined effect of plant growth regulators (PGRs), namely 2,4-D and proline as well as NAA (naphthalene acetic acid) and BAP (6-benzyl amino purine) was investigated on embryogenic callus induction and regeneration, respectively. The results showed that callus induction was significantly faster in the seed explants compared to leaf whorl. The optimal medium used to obtain a large induction in the seed explants was MS salt containing 3 mg L-1 2,4-D and 5000 mg L-1 proline, which gave a 68% yield. Furthermore, the best medium used to obtain a high plant regeneration frequency was the MS medium containing 0.1 mg L-1 NAA and 3 mg L-1 BAP, which regenerated 78% of the callus into plantlet. The addition of 560 mg L-1 proline to the combination medium increased doubled the regeneration into the planlet. Based on the results, PGRs combinations are required to improve embryogenic callus induction and regeneration into planlet in sorghum. © 2022 Friends Science Publishers

Abstract: Elderly is a phase towards the end in the span of development of human life. At this stage according to Erikson's theory of psychosocial development, is to reach the stage of integrity vs despair. Some of the characteristics at the Integrity stage are the period when the elderly are full of success towards the achievement of the previous stage of development. And vice versa Despair can be characterized by a sense of dissatisfaction with his life in the past that he has lived, there is a feeling of hopelessness, feels his life is bitter, and considers it a failure. Despair in development is related to the problem of loneliness experienced by the elderly. If you review the various studies on loneliness, the elderly can be included at a stage that is vulnerable to feelings of loneliness. The purpose of this study was to explore loneliness in the elderly during the Covid-19 pandemic. This study uses a descriptive qualitative approach. The research subjects were the elderly who were more than 60 years old. Data collection techniques using the interview method. The results of this study indicate that the pandemic causes the elderly to limit activities and interactions with their peers. Lack of social interaction and the emergence of feelings of boredom due to social restrictions cause some elderly to experience social loneliness or social loneliness. In addition, restrictions on activities during the pandemic have caused some elderly people to become passive and some other elderly people try to stay active.

Di fase ini, menurut Erikson dalam teori perkembangannya merupakan tahap integrity versus despair yaitu tahap dimana lansia akan merasa pencapaiannya telah sukses di tahap perkembangan sebelumnya atau justru merasa tidak puas dengan pencapaiannya di tahap sebelumnya sehingga menimbulkan perasaan gagal, putus asa, dan getir. Despair yang dijelaskan oleh Erikson sangat berkaitan dengan perasaan kesepian pada lansia. Beberapa studi juga menjelaskan terkait kesepian, dimana individu yang memasuki usia lansia sangat rentan dengan perasaan kesepian. Penelitian ini memiliki tujuan untuk mengeksplorasi perasaan lansia terkait kesepian di saat pandemi covid-19. Peneliti menggunakan pendekatan kualitatif deskriptif dengan subjek lansia yang berusia 60 tahun atau lebih. Peneliti menggunakan metode wawancara sebagai teknik pengumpulan data. Penelitian ini menghasilkan bahwa pandemi menyebabkan lansia membatasi kegiatan dan interaksi dengan teman sebaya mereka. Kurangnya interaksi sosial dan timbulnya perasaan bosan akibat pembatasan sosial menyebabkan beberapa lansia mengalami kesepian secara sosial atau social loneliness. Selain itu pembatasan kegiatan saat pandemi menyebabkan beberapa lansia menjadi pasif dan beberapa lansia lainnya berusaha untuk tetap aktif.

Abstract: Speech delay is a type of communication disorder indicating that an individual experiences disorder in the symbolic process of communicating. A child is said to have a speech delay if their speech development is below the level of speech quality development of children at their age. This study aims to determine the psychological picture of pre-school children who have speech delays, the causes of speech delays, the treatment, and the development after receiving the treatment. This study is qualitative research with a case study approach that focuses on the problem of speech delay in pre-school children. Researchers took the subject of 2 boys aged 3 and 5 years who have a speech delay. Data analysis was carried out using descriptive analysis, namely analyzing, describing, and summarizing various conditions of the subject from the results of interviews and observations regarding the problem under study. The result showed that children with speech delay have a different psychological condition from normal children—emotional, cognitive, and behavior. Differences were found specifically in the emotions of the children which were influenced by how the people or the environment accompanied them.

Published: May 2022

In this paper, we present our research, where residents purchase and sell locally produced renewable energy from each other. In this research work, we integrate block chain technology to create peer-to-peer marketplaces for distributed energy. First, we use a smart energy meter to measure various important parameters of electrical energy. In this proposed work, the initial measurements of the current are being performed with the help of hall effect sensor due to its accuracy. Second, supply voltage is calculated with the help of a transformer and DC biasing method. The apparent power is calculated by multiplying the measured current and voltage, and then the energy parameter is obtained. Using this smart energy meter, we obtain our desired parameters with sufficient accuracy of nearly 90 percent. These obtained parameters and results are directly uploaded to Amazon Web Server(AWS). We also develop an android app that connects with the AWS server. The designed system facilitates the users to perceive these electrical parameters on meter having built-in LCD display which shows all measured results including a number of units consumed, and billing information anywhere around the world. Finally, we develop a smart contract on Ethereum block chain which can transact the number of tokens according to the units sold or purchased by the users. The Consumer can set their selling rate through the app. Any user with this app is able to take their readings live to their smart phone.

Background: Intra-uterine contraceptive device (IUCD) insertion recommended within 10 min of placental delivery or within 48 hours of delivery is called postpartum IUCD according to WHO. Aim of the study was to evaluate the factors affecting knowledge and the likely acceptance of the postpartum intrauterine contraceptive device (PPIUCD).Methods: The present descriptive cross-sectional study was carried out in the Department of Obstetrics and Gynaecology at S. P. Medical College and associated group of hospitals, Bikaner, Rajasthan, India from May 2020 to July 2020. Total 500 post-partum women were studied with the help of predesigned and pretested questionnaire. Knowledge of the women was summarized as proportion. Chi-square test was used to compare proportions and univariate analysis for the factors affecting knowledge and likely adoption of PPIUCD.Results: The 210 (42%) women out of 500 women had knowledge regarding PPIUCD. Multiparity (p=0.003), education above secondary level {OR=11.66 (95% CI=7.13-19.06), p=0.00}, upper middle and middle socioeconomic status {OR=6.77 (95% CI=4.44-10.16), p=0.00} and health worker counselling {OR=13.61(95% CI=8.78-21.10), p=0.00} were significantly associated with knowledge. Multiparous women (p=0.004), women who had discussed PPIUCD with their husband (p<0.0001), women with family support for their decision (p<0.00001), women without religious beliefs (p<0.0001) were more significantly associated with adoption of PPIUCD.Conclusions: The level of knowledge of our study population regarding PPIUCD is 42%. Our study has reported education and regular health care worker counselling as most important modifiable predictors to improve the knowledge regarding PPIUCD.

Background: The aim of the study was to choose best method for management of fissure-in-ano. By comparing among zinc oxide pomade, lidocaine pomade and lateral internal sphincterotomy for treatment of anal fissure.Methods: 90 patients who were diagnosed with anal fissure between 2019 and 2021 at our MGM Medical College and M. Y. Hospital were undertaken for this prospective randomized trial. All cases randomized into three groups. Group 1 were the patients who applied 15% of zinc oxide pomade twice a day. Group 2 were the patients would apply 5% of lidocaine pomade twice a day. Group 3 were those undergone with lateral internal sphincterotomy. Healing rates, pain relief, recurrences, changes in symptoms after the treatment and complications were recorded.Results: There were no statistical difference among groups in terms of age and gender. The healing and symptomatic relief in the sphincterotomy group significantly much more when compared to the other groups (p=0.05). Recurrence rate is very less in sphincterotomy group.  Conclusions: Lateral internal sphincterotomy is better treatment option when compared to zinc oxide and lidocaine. There was no difference between zinc oxide and lidocaine treatments.
The Melancholy Monument of the Left
Authors: Rethmann Petra
Published: May 2022

From November 2017 to April 2018, in Mexico City’s MuseoUniversitario Arte Contemporaneo, the Russian artistic-activist collectivechto delat (what should be done?) exhibited a number of monuments inmemory of the Russian revolution. In centring on three monuments, in thisarticle I consider the ability of the collective’s monuments to inspire politicalmediations on historical potential embedded in revolutionary pasts. I arguethat melancholia does not inevitably mark historical fixity or unaccomplishedmourning, but rather a temporal openness to mnemonic productivity andsolidarity. It is in this sense that melancholia does not index a pathologicalresponse to loss, but a political alternative to normative mourning. Inrecuperating melancholia as a potentially productive and critical relation to thepast, chto delat reframes accusations of left-wing melancholia as being “stuckin the past” as an opening to consider alternatives to what is now.

The Canadian Anthropology Society is working to address sexualharassment and violence at institutional and community-based settings whereanthropologists undertake their work. In 2021, the newly formed SexualHarassment and Violence Working Group held a roundtable at the CASCAconference to start a conversation about sexual violence among CASCAmembers and to workshop best practices to prevent, disrupt, and respondto incidents of sexual harassment and violence that CASCA members mayexperience or observe. Here, the Working Group summarizes the process ofplanning, implementing, and following up the roundtable, focusing on specificactions taken by the organizers to ensure a safe conversational space before,during, and after the event. We demonstrate how the roundtable aligns withinthe larger framework of CASCA’s institutional history and future. The goalof this report is to provide a framework for convening difficult conversationsin professional settings, especially in an online environment. We providerecommendations to this end, and emphasize the need to hold furtherconversations to combat the air of silence that remains, even in a post-#MeTooworld, surrounding sexual violence in anthropology.
Maintaining the Carceral Echo Chamber: Tensions Within the Anti-Trafficking Movement in Canada
Authors: McFadyen Nicole
Published: May 2022

The anti-trafficking movement in Canada has grown rapidly since thelate 2000s, branding itself as a feminist human rights-based effort to eliminatehuman trafficking and taken up by the Government of Canada to position itselfas a benevolent leader on the international stage. Focusing on the membershipof an anti-trafficking coalition in Toronto, Canada, this article explores how themovement creates moral spaces that validate a wide range of anti-traffickingefforts. In unpacking how tensions between members are navigated throughthe suppression of direct conflict and an ethos of collaboration, it demonstrateshow carceral feminist approaches to imagining and eliminating humantrafficking continue to remain dominant despite a growth in the efforts ofindividual members to promote harm reduction and reduce the criminalizationof marginalized communities.
