Knowledge Mapping of Grassroots Consultative Democracy Research in China (2004-2020) – Bibliometric Analysis Based on CNKI Database
Authors: Duan Ying , Zhang Ying , Wang Yi-Luo
Published: April 2021

Since 2003, the term "consultative democracy" has received more and more attention from Chinese scholars, and more research results have been formed. In general, these documents lack the analysis of the research stage and research hotspots in this field. Therefore, this article uses the Chinese Academic Journals Network Publishing Library (CNKI) as the data source, and uses the common word analysis and cluster analysis methods in the CiteSpace software to analyze 500 Chinese core journals in the field of grassroots deliberative democracy in my country from 2004 to June 2020. The literature conducts a text quantitative analysis. The study found that the research hotspots of grassroots deliberative democracy in our country focused on Chinese characteristics, party leadership, national governance and political consultation. Compared with capitalist democracy, socialist democracy with Chinese characteristics is a comprehensive, extensive and true democracy, and the realization of democratization at the grassroots level is the unity of electoral democracy and deliberative democracy. Based on the above research results, the following suggestions are proposed: focus on improving the ability of grassroots masses to consult democracy; in the context of the new era, broaden the development path of grassroots consultative democracy.

A future agenda for environmental restorative justice?

The challenges of developing meaningful environmental regulation to protect communities and the environment have never been greater. Environmental regulators are regularly criticised for failing to act hard and consistently, in turn leading to demands for harsher punishments and more rigorous enforcement. Whilst acknowledging the need for strong enforcement to address wantonly destructive practices threatening communities and ecosystems, we argue that restorative approaches have an important role. This article explores a future agenda for environmental restorative justice through (1) situating it within existing scholarly and practice-based environmental regulation traditions; (2) identifying key elements and (3) raising particular theoretical and practical challenges. Overall, our vision for environmental restorative justice is that its practices can permeate the entire regulatory spectrum, going far beyond restorative justice conferences within enforcement proceedings. We see it as a shared and inclusive vision that seeks to integrate, hybridise and build broader ownership for environmental restorative justice throughout existing regulatory practices and institutions, rather than creating parallel structures or paradigms.
Why an atmosphere of transhumanism undermines green restorative justice concepts and tenets

Why an atmosphere of transhumanism undermines green restorative justice concepts and tenets

Arising from the notions of green criminology and green victimology, green restorative justice can be defined as a restorative justice focused on environmental harm. Harm in this case is understood as criminalised and non-criminalised, and as individual and collective behaviours damaging the ecosystems and the existence of human and non-human beings. Impacts of environmental harm affect health, economic, social and cultural dimensions, and will be experienced in the short, medium and long term. Within this framework, after linking restorative justice to green criminology and green victimology, I will argue that the current weight of the cultural and social movement of transhumanism constitutes an obstacle to the development of restorative justice in this field. The reason is that it fosters individual narcissism, together with the idea of an absence of limits in what is considered technological progress. This progress is seen as inevitable and good per se, and promotes the perception of a lack of social and moral accountability. This reasoning will lead to some final reflections on how restorative justice has to constantly reinvent itself in order to keep creating a critical and inclusive justice of ‘otherness’. By doing so, restorative justice must join the current interdisciplinary conversation on biopolitics and bioethics.

Published: April 2021

PurposeTo describe the utilization trends of a dedicated ophthalmology emergency department (ED) in Boston, Massachusetts.MethodsThe medical records of 500 randomly selected patients who presented at the Massachusetts Eye and Ear (MEE) Emergency Department (ED) from January 2015 to March 2016 were reviewed retrospectively. Data were analyzed using the Pearson χ2 test and multiple logistic regression. The primary study outcome measure was whether a patient’s visit was emergent or nonemergent. Emergent or nonemergent conditions were classified based on the diagnosis and treatment required at follow-up appointments. Nonemergent diagnoses were classified as conditions that could have been seen as an outpatient without negative consequences for vision.ResultsOf the 500 cases, 252 were males and 248 were females. The median age was 45 years (range, 2- 101 years). The most common diagnoses were posterior vitreous detachment (8.6%), corneal abrasion (8.4%), dry eye syndrome (7%), and viral conjunctivitis (5.4%). Of the total, 92.6% of patients originated from within Massachusetts. The majority of patients were self-referred (78.6%) or referred from another hospital (12.8%). Nonemergent visits accounted for 49.4% of patients seen. Compared to patients who presented with duration of symptoms for ?1 week, patients who presented with symptoms of <1 week were more likely to present with an emergent condition (8.8% vs 41.8%). Referrals from an outside ophthalmologist or hospital were predictive of emergent patient visits (OR, resp., 1.971 [95% CI, 0.478-3.462; P = 0.01]; 1.040 [95% CI, 0.462-1.616; P < 0.001]).ConclusionsIn our study, nonemergent patient visits comprised nearly half of all ophthalmology ED visits. Emergent visits were associated with acute symptoms and referrals from outside healthcare providers.

Published: April 2021

Uveal melanoma size is a significant predictor of tumor metastasis. Although the relationship between antivascular endothelial growth factors (VEGF) and uveal melanoma growth has been studied, results are paradoxical, and the relationship remains controversial. We report the case of a 65-year-old man who presented with elevated intraocular pressure in his right eye, neovascularization of his iris, and significant corneal edema, which obscured the view of the angle. Given his history of proliferative diabetic retinopathy, he was diagnosed with neovascular glaucoma and subsequently received an intravitreal injection of bevacizumab and underwent Ahmed valve insertion. This was complicated by postoperative hyphema. Two and a half months postoperatively, a mass involving the inferior iris and ciliary body became visible, and fine-needle aspiration biopsy confirmed uveal melanoma. Seven weeks after diagnosis, the tumor’s largest basal diameter had increased from 2.51 mm to 18.0 mm, and apical height increased from 6.23 mm to 11.0 mm. His right eye was enucleated. Histopathological analysis showed discontinuous invasion next to the Ahmed valve. Tumor progression after injection raises the possibility that in some untreated uveal melanomas, accelerated growth may occur following exposure to anti-VEGF agents.
Ultrasonic Detection of Down Syndrome Using Multiscale Quantiser with Convolutional Neural Network
Authors: Dinesh Simon Michael , Kavitha A.R.
Published: April 2021

Down Syndrome is a genetic condition that occurs when there is an extra copy of a chromosome 21 in the newly formed fetus. EIF is observed as one of the possible symptoms of DS. But in comparison to the other symptoms like nasal bone hypoplasia, increased thickness in the nuchal fold, EIF is very much less prone to DS. Hence, recommending the pregnant women with EIF to undergo the diagnostic process like amniocentesis, CVS and PUBS is not always a right choice as these diagnostic processes suffer serious drawbacks like miscarriage, uterine infections. This chapter “Ultrasonic Detection of Down Syndrome Using Multiscale Quantiser With Convolutional Neural Network” presents a new ultrasonic method to detect EIF that can cause DS. Ultrasonic Detection of Down Syndrome Using Multiscale Quantiser with Convolutional Neural Network entails two stages namely i) training phase and ii) testing phase. Training phase aims at learning the features of EIF that can cause DS whereas testing phase classifies the EIF into DS positive or DS negative based on the knowledge cluster formed during the training phase. A new algorithm Multiscale Quantiser with the convolutional neural network is used in the training phase. Enhanced Learning Vector Classifier is used in the testing phase to differentiate the normal EIF from EIF causing DS. The performance of the proposed system is analysed in terms of sensitivity, accuracy and specificity.

Published: April 2021

With an aging population, chronic osteoarthritic hip joint pain is becoming a major issue. Most patients with hip pain can control their pain with conservative measures but with a gradual reduction in their quality of life. When gradually reduced ambulation and pain become recalcitrant, total hip arthroplasty is the next step. For most patients, this is a good way to improve pain control and to recover some quality of life, but for a few this aggressive surgical procedure is not possible. Sometimes co-morbidities make total hip arthroplasties undesirable. At other times, the age of the patients recommends to wait for a while. In these cases, other options have to be explored. Percutaneous partial hip joint sensory denervation has become a notable option as it can provide acceptable rates of pain relief with minimal surgical aggressiveness. There are three modalities to perform it: thermal, cooled and pulsed radiofrequency.
Microbial Hydrolysed Feather Protein as a Source of Amino Acids and Protein in the Diets of Animals Including Poultry
Authors: Kumar Jitendra
Published: April 2021

Feathers are hard waste products, mainly composed of hard β-keratin, and are produced in large quantities in commercial poultry processing plants. Therefore, their industrial utilization is important economically as well as environmentally. Feathers degradation through keratinolytic microorganisms has been considered as an important method for efficient bioconversion, nutritional enhancement and eco-friendliness. The use of crude keratinase significantly increased the amino acid digestibility of raw feathers and commercial feather meal. This enzyme increased the digestibility of commercial feather meal and could replace as much as 7% of the dietary protein for growing chicks. However, feathers are currently utilized on a limited basis as a dietary protein supplement for animal feed because feather meal production is an expensive process, requiring significant amounts of energy. This review paper explains the nutritive value of feathers which makes suitable and inexpensive animal and poultry feed.
Stabilizing Zero-Field Skyrmions at Room-Temperature in Perpendicularly Magnetized Multilayers
Authors: Brandão Jeovani , Vinicius Puydinger dos Santos Marcos , Béron Fanny
Published: April 2021

Magnetic skyrmions are twirling spin structures observed in bulk, thin films, and multilayers with several features for both fundamental physics understanding and spintronic applications, i.e., nanoscale size, efficient transport under electrical current, and topological protection against defects. However, most magnetic skyrmions have been observed under the assistance of an out-of-plane magnetic field, which may limit their use in magnetic memory technologies. In this chapter, we review and present two recent mechanisms to create zero-field skyrmions at room-temperature in ferromagnetic multilayers. First, by tuning the perpendicular magnetic anisotropy (PMA) and remnant magnetization (near magnetization saturation) in unpatterned symmetric multilayer systems, it was achieved a transition from worm-like domains to isolated skyrmions. Besides, we present how to find stable zero-field skyrmions in arrays of ferrimagnetic discs by tailoring their diameter. Both methods demonstrate a robust route to stabilize zero-field skyrmions at room temperature, thus providing an important contribution to possible applications of these textures in the next generation of skyrmionics devices.
Les prolongements psychiques de la sécurité du stoïcisme antique à la résilience néolibérale : l’inconscient esclave comme technologie d’adaptation au monde
Authors: Munger Sylvain
Published: April 2021

La vulnérabilité (du latin vulnerare signifiant blesser ou endommager) désigne un degré d’affaiblissement qui diminue la réserve des capacités accumulées par un être humain indispensables afin de résister aux stimulations et aux agressions environnementales. La mondialisation néolibérale accélère la multiplication en cascade des événements déstabilisants et des conditions de vie difficiles, constitués de précarités économiques, de privations sociales, de crises écologiques et sanitaires produites en série et vécues au quotidien par les populations. Dans ces conditions, la résilience consiste en un commandement suivi par chacun et signant l’acte de décès de son engagement dans le monde ; c’est surtout l’obligation de se résigner à son état actuel. Or, cette capacité à rebondir en force, à tenir son fonctionnement en absorbant le choc pour se renouveler et s’adapter, on en retrace la présence dans l’Antiquité, dans la doctrine stoïcienne, technique d’enseignement d’une « morale d’esclave » transformée en disposition psychologique durable.
Rhétoriques réactionnaires et antiféminisme en France : la controverse de l’écriture inclusive1
Authors: Michaud Héloïse
Published: April 2021

En France, en mars 2017, l’éditeur Hatier publiait un manuel scolaire qui utilisait l’écriture inclusive, dont l’objectif était d’éradiquer le sexisme dans la langue et donc dans les mentalités. Les résistances à son application furent nombreuses : l’Académie française, le groupe parlementaire Les Républicains dont était issu le premier ministre français Édouard Philippe, des militant·e·s de la « Manif pour tous » et des intellectuel·le·s se sont prononcés publiquement contre cette tentative d’inclusivité dans la langue française. Dans cette étude, nous proposons d’évaluer en quoi les arguments invoqués lors de la controverse de l’écriture inclusive en France s’arriment à des rhétoriques réactionnaires antiféministes.
Suivez-nous sur Facebook… Et après ? La communication en ligne des conseils de quartier de Québec
Authors: Dubois Philippe R.
Published: April 2021

Cette étude présente une analyse de contenu d’un échantillon aléatoire de 311 publications mises en ligne sur les pages Facebook des conseils de quartier de Québec. L’objectif est de comprendre comment cet organisme citoyen de participation politique microlocale en quête de reconnaissance utilise les médias sociaux pour communiquer avec les résident·e·s. L’analyse montre que la communication à sens unique est l’approche privilégiée. Cette dernière ne peut contribuer à la création d’un espace « cyberdémocratique ». Qui plus est, il ne semble pas y avoir une véritable stratégie concertée de promotion du rôle et des actions des conseils de quartier. Le contenu que ces organismes publient sur leurs pages Facebook est plutôt de l’ordre d’un babillard communautaire. Sur le plan méthodologique, l’article met en lumière l’importance d’étudier le rôle réservé aux récepteur·rice·s de la communication en ligne, surtout dans les études qui cherchent à relever ses fonctions (information, promotion, interaction, mobilisation).

Forecasting the All-Weather Short-Term Metro Passenger Flow Based on Seasonal and Nonlinear LSSVM
Authors: Huang Xin , Wang Yimin , Lin Peiqun , Yu Heng , Luo Yue
Published: April 2021

Accurate metro ridership prediction can guide passengers in efficiently selecting their departure time and simultaneously help traffic operators develop a passenger organization strategy. However, short-term passenger flow prediction needs to consider many factors, and the results of the existing models for short-term subway passenger flow forecasting are often unsatisfactory. Along this line, we propose a parallel architecture, called the seasonal and nonlinear least squares support vector machine (SN-LSSVM), to extract the periodicity and nonlinearity characteristics of passenger flow. Various forecasting models, including auto-regressive integrated moving average, long short-term memory network, and support vector machine, are employed for evaluating the performance of the proposed architecture. Moreover, we first applied the method to the Tiyu Xilu station which is the most crowded station in the Guangzhou metro. The results indicate that the proposed model can effectively make all-weather and year-round passenger flow predictions, thus contributing to the management of the station.
Hierarchical Passenger Hub Location Problem in a Megaregion Area Considering Service Availability
Authors: Yan Huang , Zhang Xiaoning , Wang Xiaolei
Published: April 2021

The rapid growth of the intercity travel demand has resulted in enormous pressure on the passenger transportation network in a megaregion area. Optimally locating hubs and allocating demands to hubs influence the effectiveness of a passenger transportation network. This study develops a hierarchical passenger hub location model considering the service availability of hierarchical hubs. A mixed integer linear programming formulation was developed to minimize the total cost of hub operation and transportation for multiple travel demands and determine the proportion of passengers that access hubs at each level. This model was implemented for the Wuhan metropolitan area in four different scenarios to illustrate the applicability of the model. Then, a sensitivity analysis was performed to assess the impact of changing key parameters on the model results. The results are compared to those of traditional models, and the findings demonstrate the importance of considering hub choice behavior in demand allocation.
Estimating Urban Road Transport Vehicles Emissions in the Rijeka City Streets
Authors: Maglić Livia , Krljan Tomislav , Grubišić Neven , Maglić Lovro
Published: April 2021

The growing demand for private and public transport services in urban areas requires sophisticated approaches to achieve satisfactory mobility standards in urban areas. Some of the main problems in urban areas today are road congestions and consequently vehicle emissions. The aim of this paper is to propose a methodological approach for the estimation of vehicle emissions. The proposed methodology is based on two interrelated models. The first model is a microscopic simulation SUMO model which can be used to identify the most congested urban areas and roads with critical values of traffic parameters. The second model is the COPERT Street Level for estimating vehicle emissions. The proposed models were tested on the urban area of Rijeka. The results of the microscopic SUMO simulation model indicate six urban roads with the critical traffic flow parameters. On the basis of the six identified urban roads, an estimation of vehicle emissions was carried out for specific time periods: 2017, 2020, 2025, and 2030. According to the results of the second model, the urban road R20-21 was identified as the most polluted road in the urban district of Rijeka. The results indicate that over the period 2017–2030, CO emissions will be reduced on average by 57% on all observed urban roads, CO2 emissions by 20%, and PM emissions by 58%, while the largest reduction of 65% will be in NOx emissions.
Interoception as a social alarm amplification system. What multimethod (EEG-fNIRS) integrated measures can tell us about interoception and empathy for pain?
Authors: Balconi Michela , Angioletti Laura
Published: April 2021

We examined whether the modulation of Interoceptive Attentiveness (IA) influences the cortical correlates of observation of pain in others. Healthy participants observed painful/non-painful stimuli while brain response [oxygenated and deoxygenated hemoglobin (O2Hb; HHb), and electroencephalographic cortical oscillations] was measured. Participants were divided into experimental (EXP) and control group: EXP group was required to focus on its interoceptive correlates during the task. Interpersonal Reactivity Index (IRI) scale was administered to test empathic traits. Focusing on prefrontal cortex activity, theta band and O2Hb in the right frontal hemisphere while observing painful stimuli positively correlates in the EXP. Delta band and O2Hb in left frontal hemisphere for non-painful stimuli positively correlates in controls. IRI (Perspective Taking and Empathic Concern subscales) and right frontal activity for painful stimuli negatively correlates in the EXP. Findings were discussed in light of the modulating role of IA in enhancing the negative experience of observing pain in others.
Tramas transnacionales del cuidado: una “lucha con los ángeles”, teoría y metáforas sobre cuidado y migración
Authors: Esguerra Muelle Camila
Published: April 2021

In this article, I further explore the theoretical proposal of what I call transnational care plots. I do so based on an approximately decade-long research agenda on migration and care, using over a hundred stories and nearly fifty body mappings derived from a multi-sited and collaborative ethnography conducted in Colombia and Spain (Cali, Medellin, Cartagena, Bogota, Barcelona, and Madrid). I draw on the notion of global care chains, as coined by Arlie Hochschild, to provide a metaphor that leads to a more fluid and acute mental picture of the number and complexity of the intertwining trajectories of those who migrate and care in a world that does not yet give fair recognition to the implications of the transnationalized care regime on life in general, and on the lives of migrants in particular. Drawing on Stuart Hall’s dissertations on the usefulness of metaphors in the domain of theorizing — what he calls “wrestling with angels” — and on narratives constructed from multisite ethnography and a reflexive approach, I develop the image of transnational care plots as a metaphor with discursive, somatic, political, aesthetic and affective dimensions. Little has been written about Colombia’s place in these chains or plots, despite the fact that it is one of the central countries in the operation of the transnationalized care regime. At the same time, I develop a complexification of the so far little explored notion of global care chains, which is essential to envisioning and shaping the narratives of migrant care workers and to understand the politics of dispossession involved there. This, in turn allows us to imagine possible futures that go against the tide and which “wrestle with the angels.”
Annotation
Authors: Kalir Remi H. , Garcia Antero
Published: April 2021

An introduction to annotation as a genre—a synthesis of reading, thinking, writing, and communication—and its significance in scholarship and everyday life.

Annotation—the addition of a note to a text—is an everyday and social activity that provides information, shares commentary, sparks conversation, expresses power, and aids learning. It helps mediate the relationship between reading and writing. This volume in the MIT Press Essential Knowledge series offers an introduction to annotation and its literary, scholarly, civic, and everyday significance across historical and contemporary contexts. It approaches annotation as a genre—a synthesis of reading, thinking, writing, and communication—and offers examples of annotation that range from medieval rubrication and early book culture to data labeling and online reviews.

After introducing such ideas as paratext, multimodality, and intertextuality, the authors discuss the affordances and types of annotation in a variety of contexts. Annotation that provides information, for example, can be a time stamp on a text message or a footnote to a text; annotation that shares commentary can be praise (or the opposite) on Rate My Professors or the texts in the Hebrew Talmud; and annotation that aids learning can be added by experts for students or by students for their peers. Far from being an arcane practice of scholars, annotation allows readers to respond to their texts, interact with various forms of media, and make meaning with and from this everyday activity.
The Monopoly of Man
Authors: Kuliscioff Anna
Published: April 2021

A key text by a leading figure in Italian socialist feminism that remains relevant today, addressing the exploitation of women in the workplace and at home.

Anna Kuliscioff (c. 1854–1925) was a prominent figure in the revolutionary politics of her era, advocating for socialism and feminism. One of the founding members of the Italian Socialist Party, she actively contributed to the late-nineteenth-century flourishing of the Socialist International and the emergence of Italian socialism. For the last decades of her life, Kuliscioff's public militancy revolved around the “woman question.” She viewed feminism through the lens of class struggle, addressing the double exploitation of women—in the workplace and at home. Kuliscioff fought a twofold battle: as a socialist, she unmasked the sexism of her colleagues; as a feminist, she criticized liberal-bourgeois feminism. In this key text, she makes her case for a socialist feminism.

Originating as a lecture Kuliscioff delivered in April 1890 at a meeting of the the Milan Philological Circle (which denied membership to women), The Monopoly of Man explicitly links feminism to labor. Kuliscioff argues that labor frees women from the prison of the household and potentially fosters their emancipation; she advances the principle of equal pay for equal work. She declares that woman is enslaved by both her husband and by capital, calls marriage a form of women's servitude, and demands that motherhood be better appreciated as work. It is only when woman is economically independent and resists capitalism, she argues, that she will achieve freedom, dignity, and the respect of man.

The Monopoly of Man is the inaugural title in a new series, Insubordinations: Italian Radical Thought, edited by Lorenzo Chiesa.
Friedrich Christoph Mayer and his theory of the aurora borealis
Authors: Chassefière Eric
Published: April 2021

The eleventh volume in the series presents two articles on the aurora borealis by Friedrich Christoph Mayer (1697–1729), a mathematician at the Imperial Academy of Sciences in Saint Petersburg. The first paper, titled “De Luce Boreali” (On the Northern Light), was presented during a session at the newly founded Academy in October 1726. It was printed two years later (1728) in the very first volume of its official periodical, the Commentarii Academiae Scientiarum Imperialis Petropolitanae. The second paper, also bearing the title “De Luce Boreali”, constitutes the author’s ‘second thoughts’ on the matter. It was presented during a session in October 1728 but was not printed until after Mayer’s death, in the fifth volume of the Commentarii (1735). Both papers are included in facsimile in this issue of Aurorae Borealis Studia Classica.

Eric Chassefière, member of the Histoire des sciences astronomiques team of the SYRTE laboratory at the Observatoire de Paris, has written an introduction to Mayer’s life and works with a special emphasis on his theory of the aurora borealis. In his introduction, Chassefière also recounts how Mayer’s theory was received by other eighteenth-century savants.
Delay minimization based uplink resource allocation for device-to-device communications considering mmWave propagation
Authors: Ferreira Marcus V.G. , Vieira Flávio Henrique Teles
Published: April 2021

This paper addresses the resource allocation problem in multi-sharing uplink for device-to-device (D2D) communication, one aspect of 5G communication networks. The main advantage and motivation in relation to the use of D2D communication is the significant improvement in the spectral efficiency of the system when exploiting the proximity of communication pairs and reusing idle resources of the network, mainly in the uplink mode, where there are more idle available resources. An approach is proposed for allocating resources to D2D and cellular user equipments (CUE) users in the uplink of a 5G based network which considers the estimation of delay bound value. The proposed algorithm considers minimization of total delay for users in the uplink and solves the problem by forming conflict graph and by finding the maximal weight independent set. For the user delay estimation, an approach is proposed that considers the multifractal traffic envelope process and service curve for the uplink. The performance of the algorithm is evaluated through computer simulations in comparison with those of other algorithms in the literature in terms of throughput, delay, fairness and computational complexity in a scenario with channel modeling that describes the propagation of millimeter waves at frequencies above 6 GHz. Simulation results show that the proposed allocation algorithm outperforms other algorithms in the literature, being highly efficient to 5G systems.
Carcinosarcoma Stomach with Biphasic Nodal Metastasis: A Rare Entity
Authors: Sukumaran Renu , Katoor Jayasree , Mathew Arun Peter
Published: April 2021

Gastric carcinosarcoma is an extremely rare, aggressive, biphasic tumour composed of a mixture of carcinomatous and sarcomatous elements. Clinical symptoms and imaging studies of carcinosarcoma are not different from that of carcinoma. Biopsy of the lesions may not include both components. Thus, a diagnosis of carcinosarcoma is often rendered in surgical specimens. Immunohistochemistry will help to identify the various components. The relative proportion of the carcinomatous and sarcomatous elements is variable. One of the components may dominate the histologic picture. The common carcinomatous component described is adenocarcinoma with rare cases, showing neuroendocrine and squamous elements. The sarcomatous elements include spindle cell sarcoma which was Not Otherwise Specified (NOS), leiomyosarcoma, fibrosarcoma, osteosarcoma, chondrosarcoma, liposarcoma, undifferentiated sarcoma, myxoid sarcomas, and rhabdomyosarcoma. Herein, the authors are reporting the case of a 62-year-old female patient who presented with abdominal pain and vomiting of three-month duration. Endoscopic examination revealed a large polypoidal mass lesion in the body of stomach. Subtotal gastrectomy was done which showed large polypoidal mass lesion measuring 12×9.5×6 cm. Histopathological examination revealed a biphasic neoplasm with close intermingling of malignant epithelial and mesenchymal elements. Carcinoma component showed glandular, squamous and neuroendocrine areas. The sarcomatous component was spindle cell sarcoma, NOS. On immunohistochemical examination, epithelial component showed cytokeratin positivity. The neuroendocrine component was positive for synaptophysin, chromogranin A and CD56. The p40 positivity noted in the squamous component. The mesenchymal component showed positivity for vimentin. The nodal metastasis showed admixture of carcinoma (glandular and squamous components) and sarcoma.

Published: April 2021

Introduction: Carbapenem Resistant Enterobacteriaceae (CRE) are major cause of community as well as healthcare associated infections and have limited treatment options. Measuring the magnitude of the problem of CRE, it is important for making strategies to lower its spread. Aim: To assess the incidence and prevalence rate of CRE in a tertiary care hospital of Gujarat, India. Materials and Methods: Retrospective data was collected for a period from 2014 to 2018 using Laboratory Information System (LIS). Prevalence of CRE was determined as number of CRE isolated per 100 Enterobacteriaceae isolated during the study period whereas incidence rate was determined as number of CRE cases per 1000 patient-days. Consumption of Carbapenems was calculated as Defined Daily Dose (DDD) per 1000 patient-days. Demographic data including age, gender, location in the hospital and sample type from which CRE was isolated was also analysed using Microsoft Excel. Results: The incidence of CRE cases per 1000 patient-days in 2014 to 2018 was 1.66, 2.11, 1.90, 2.26 and 1.91, respectively with an overall incidence of 1.99 per 1000 patient-days. The overall prevalence of CRE over a period of five years was found to be 29.07%. Klebsiellasp. was the most common CRE and had the highest percentage of Carbapenem resistance among all Enterobacteriaceae. Conclusion: The rate of CRE in present study was high and worrisome. Screening of the patient for CRE, source isolation and stringent implementation of infection control practices is required to confine the spread of CRE in this institute.
Sigma Metrics: A Powerful Tool for Performance Evaluation and Quality Control Planning in a Clinical Biochemistry Laboratory
Authors: Ramteke Trupti Diwan , Chalak Anita Shivaji , Maksane Shalini Nitin
Published: April 2021

Introduction: Any error in the laboratory testing processes can affect the diagnosis and patient management. Six Sigma is a data driven quality management system for identifying and reducing errors and variations in clinical laboratory processes. Aim: This study was carried out to estimate Sigma metrics of various biochemical analytes in order to evaluate performance of quality control and implement optimum quality control strategy for each analyte. Quality goal index (QGI) was also calculated to identify the problems of inaccuracy and imprecision for parameters having lower sigma values. Materials and Methods: This retrospective, observational study was conducted at the Central Clinical Biochemistry Laboratory of Seth GS Medical College and KEM hospital in Mumbai for a period of six months (July 2019 to December 2019). Sigma metrics for 20 analytes was calculated by using internal quality control and external quality control data. Further, QGI was calculated for analytes having sigma value of <4 to identify imprecision or inaccuracy. Statistical analysis was performed using Microsoft office excel 2010 software. Results: Total protein, Glucose, Urea, Triglyceride (TAG), High Density Lipoprotein (HDL), and Low Density Lipoprotein (LDL) for normal (L1) and pathological (L2) controls achieved excellent performance (>6 sigma). Westgard rule (13s) with two control measurement (N2) per QC event and run size (R1000) i.e. 1000 patient samples between consecutive QC events was adopted for these analytes. For analytes with sigma value of 4-6, more rules (sigma 4-5: Westgardrules-13s/22s/R4s/41s, N4 and R200 and for sigma value 5-6: 13S/22s/R4s, N2 and R450) were adopted. The sigma values of six analytes (Creatinine, Sodium, Potassium, Calcium, Chloride, Inorganic phosphate) were <4 at one or more QC levels. For these analytes, strict QC procedures (Westgard rules-13s/22s/R4s/41s/6x, N4 and R45) were incorporated. QGI of these analytes was <0.8 which indicated the problem of imprecision. Staff training programs and review of standard operating procedures were done for these analytes to improve method performance. Conclusion: Sigma Metrics estimation helps in designing optimum QC protocols, minimising unnecessary QC runs and reducing the cost for analytes having high sigma metrics. Focused and effective QC strategy for analytes having low sigma helps in improving the performance of those analytes.

Extension in many countries has come to cover a variety of activities in both the public and private sectors, yet the transfer of information continues to be the ultimate focus of all extension activities. The present study was conducted in Kannur district of Kerala state, to identify the constraints of existing ITD methods implemented by different agricultural institutions in Kannur and find out the suggestions from farmers for improvement. Thirty farmers each from four selected Grama Panchayats (Ezhome, Kankol- Alapadamba, Kadannapalli- Panapuzha and Mayyil) of Kannur were identified using simple random sampling. A well-structured interview schedule was used for collecting data from the respondents. The data were tabulated and inferences were drawn after appropriate statistical analysis. The results shows that lack of awareness about the latest ICT methods for technology dissemination’ is having highest mean score (72.17) and it is considered as the most severe constraint by the farmers followed by ‘trainings are not effective to meet farmer’s needs’ (71.5) and ‘Less training programs for farmers and extension personnel (69.77).

Aims: The purpose of this paper is to appraise the perceptions of teachers on the implementation of school health services in Private and Public Secondary Schools in Ebonyi State, Nigeria.

Background: Health is an essential commodity that every living human bargain for and is the prerequisite determinant of our overall achievements be it academic, social, economic and political dimesions.

Methodology: A cross-sectional descriptive design was employed to appraise the perceptions of teachers on the implementation of school health services in private and public secondary schools in Ebonyi state. Using the multistage sampling technique a total of 160 teachers who consented to participate in the study were enrolled. A self-developed questionnaire titled: Appraisal of the Perceptions of Teachers on the Implementation of School Health Service (APTISHS) was used for data collection.

Results: The findings revealed that the perceptions of teachers on the implementation of school health services in private and public secondary schools in Ebonyi state were generally poor with the Mean score 2 and 2.2 respectively. However, despite the low perception on the implementation, private schools were more favoured than public schools in areas like: Availability of personnel (P-value: 0.00); Health records (P-value: 0.00), Quality of first aid box (P-value: 0.01).

Conclusion: While efforts are made to revamp school health services in all schools, a heightened attention should be given to public schools. For an effective implementation of the school health services government should set up an implementation and evaluation committee or monitoring team. The team should composed of stakeholders from both ministries of Education and Health, school managements in both public and private including their association bodies, parent association and the communities hosting the schools. This body will facilitate issues to be agreed upon and enforcement more realistic.

Programming magnetic fields with microscale control can enable automation at the scale of single cells ≈10 µm. Most magnetic materials provide a consistent magnetic field over time but the direction or field strength at the microscale is not easily modulated. However, magnetostrictive materials, when coupled with ferroelectric material (i.e., strain‐mediated multiferroics), can undergo magnetization reorientation due to voltage‐induced strain, promising refined control of magnetization at the micrometer‐scale. This work demonstrates the largest single‐domain microstructures (20 µm) of Terfenol‐D (Tb0.3Dy0.7Fe1.92), a material that has the highest magnetostrictive strain of any known soft magnetoelastic material. These Terfenol‐D microstructures enable controlled localization of magnetic beads with sub‐micrometer precision. Magnetically labeled cells are captured by the field gradients generated from the single‐domain microstructures without an external magnetic field. The magnetic state on these microstructures is switched through voltage‐induced strain, as a result of the strain‐mediated converse magnetoelectric effect, to release individual cells using a multiferroic approach. These electronically addressable micromagnets pave the way for parallelized multiferroics‐based single‐cell sorting under digital control for biotechnology applications.

Published: April 2021

Thermoswitchable fluorescent materials (TFMs) have received special attention due to their unique fluorescent colorimetric responses to temperature. Conventional TFMs generally display unicolor with switching from one color to another, showing unprintable and unsatisfied performances. These limitations greatly hinder their development and expansion toward advanced applications. Herein, the superior integration of full‐color, off–on switching mode, printability, and high performance to TFMs is achieved successfully. The success is due to a thermally induced synchronous “dual/multichannel” stimulus–response mode regulated by a self‐crystalline phase‐change material; that is, synergistic changes of the molecular existence states and subsequent colors/spectra of the fluorescent modifier and fluorophores, accompanied by corresponding high‐efficiency on–off switching of Förster resonance energy transfer. These TFMs are simple to prepare and show good performance, such as high fluorescence emission contrast (>100), great reversibility (>200 cycles), and easy‐to‐adjust response temperature. Particularly, these R/G/B TFMs can be prepared as tricolor fluorescent inks, and thus full‐color emissions on flexible substrate can be easily obtained by printing. Finally, their great potential in switchable dynamic interior decoration, programmatic temperature‐control information display, and senior information encryption are illustrated. This successful exploration offers a new perspective for designing and optimizing various other switchable materials with higher comprehensive performances.
