The City as a Metaphor for Order: The Prohibition on the Sale of Alcoholic Beverages at Night as a Means of Purifying Public Space

This paper discusses a segment of a study that took place between 2012 and 2015, which examined the then-existing ban on the sale of alcoholic beverages in commercial establishments at night in several Serbian cities, including Belgrade, Kragujevac, Novi Sad, Šabac, and Zrenjanin. The research also looked at how the media represented the ban from 2006 to 2013 and analysed data obtained through a questionnaire completed by 22 individuals from Belgrade in 2023.
 The study examined various aspects of the ban, including its role in the context of spatial power operation, which is discussed in this paper. The researcher began with the assumption that the ban on the sale of alcoholic beverages at night in commercial establishments could be interpreted as a way of purifying public space, through which one social group establishes dominance over others in society by controlling public space. This is achieved not only by excluding members of specific social groups from the specified place, but also by excluding socially inappropriate practices deemed typical for those groups. The ultimate goal is to organise public space so that it reflects dominant societal values and achieves dominance for the group that tends to represent those values.
 The restriction was seen to be targeted at preventing members of the lower classes and young people, as members of the aforementioned classes, from occupying public space. It also had the broader aim of prohibiting the purchase and problematic use of alcoholic beverages late at night, a practice identified in the aforementioned socioeconomic strata, where it was perceived as a possible source of disruption, violence, and a threat to upper-class citizens. The decision was an attempt to increase the safety of the higher classes by limiting the ability of members of the lower classes and youth to purchase alcoholic beverages at night, as well as through spatial segregation. Although not explicitly stated, one of the effects sought by this decision was the prohibition of alcohol consumption in public places among the aforementioned social groups.
 The purpose was to instil a sense of security in the community and to project an image of moral order in society. It represented a mechanism for the higher classes to assert their authority in society and to establish their class identity by spatially separating themselves from the classes with which they were placed in a relationship of opposition. Thus, public space was created to reflect the values advocated by upper-class citizens, such as order, self-control, moderation, and decency, which aided their dominance in society.

Identification of potential classes of glycoligands mediating dynamic endothelial adhesion of human tumor cells.

One critical step of metastasis formation is the extravasation of circulating tumor cells from the bloodstream. This process requires the dynamic interaction of cell adhesion molecules like E-selectin on endothelial cells with carbohydrate ligands on tumor cells. To characterize these glycans in a comprehensible approach, the rolling, tethering, and firm adhesion of nine human tumor cell lines on human umbilical vein endothelial cells was analyzed using laminar flow adhesion assays. The tumor cell lines were grouped into three subsets by their canonical E-selectin ligand status (sialyl-Lewis A and X +/+, -/+, -/-) and their adhesiveness was compared after enzymatic, pharmacologic, chemical treatment or antibody blockade of the tumor cells or endothelial cells, respectively. Tumor cells were also screened regarding their glycosyltransferase expression profile. We found that although E-selectin and terminal α2,3-sialic acid largely determined firm adhesion, adhesive events did not exclusively depend on the presence of sialyl-Lewis A and/or sialyl-Lewis X. Nevertheless, two of the three sialyl-Lewis A/X-/- tumor cells additionally or fully depended on vascular cell adhesion molecule-1 for firm adhesion. The significance of O-GalNAc- and N-glycans for adhesion varied remarkably among the tumor cells. The sialyl-Lewis A/X+/+ subset showed glycoprotein-independent adhesion, suggesting a role of glycolipids as well. All sialyl-Lewis A/X-/- tumor cells lacked FUT3 and FUT7 expression as opposed to sialyl-Lewis A/X+/+ or -/+ cell lines. In summary, the glycans on tumor cells mediating endothelial adhesion are not as much restricted to sialyl-Lewis A /X as previously assumed. The present study specifically suggests α2,3-linked sialic acid, O-GalNAc glycans, glycosphingolipids, and FUT3/FUT7 products as promising targets for future studies.

Identification of cytokine-predominant immunosuppressive class and prognostic risk signatures in glioma.

The advent of immune checkpoint blockade (ICB) therapies this year has changed the way glioblastoma (GBM) is treated. Meanwhile, some patients with strong PD-L1 expression remain immune checkpoint resistant. To better understand the molecular processes that influence the immune environment, there is an urgent need to characterize the immunosuppressive tumor microenvironment and identify biomarkers to predict patient survival outcomes. Our study analyzed RNA-sequencing data from 178 GBM samples. Their unique gene expression patterns in the tumor microenvironment were analyzed by an unsupervised clustering algorithm. Through these expression patterns, a panel of T-cell exhaustion signatures, immunosuppressive cells, and clinical features correlates with immunotherapy response. The presence or absence of immune status and prognostic signatures was then validated with the test dataset. 38.2% of GBM patients showed increased expression of anti-inflammatory cytokines, significant enrichment of T cell exhaustion signals, higher proportion of immunosuppressive cells (macrophages and CD4 regulatory T cells) and nine inhibitory checkpoints (CTLA4, PDCD1, LAG3, BTLA, TIGIT, HAVCR2, IDO1, SIGLEC7, and VISTA). The immunodepleted class (IDC) was used to classify these immunocompromised individuals. Despite the high density of tumor-infiltrating lymphocytes shown by IDC, such patients have a poor prognosis. Although PD-L1 was highly expressed in IDC, it suggested that there might be ICB resistance. There are many IDC predictive signatures to discover. PD-1 is strongly expressed in a novel immunosuppressive class of GBM, but this cluster may be resistant to ICB therapy. A comprehensive description of this drug-resistant tumor microenvironment could provide new insights into drug resistance mechanisms and improved immunotherapy techniques.

Multi-level color classification of post-consumer plastic packaging flakes by hyperspectral imaging for optimizing the recycling process

In a circular economy perspective, the development of fast and efficient sensor-based recognition strategies of plastic waste, not only by polymer but also by color, plays a crucial role for the production of high quality secondary raw materials in recycling plants. In this work, mixed colored flakes of high-density polyethylene (HDPE) from packaging waste were simultaneously classified by hyperspectral imaging working in the visible range (400–750 nm), combined with machine learning. Two classification models were built and compared: (1) Partial Least Square-Discriminant Analysis (PLS-DA) for 6 HDPE macro-color classes identification (i.e., white, blue, green, red, orange and yellow) and (2) hierarchical PLS-DA for a more accurate discrimination of the different HDPE color tones, providing as output 14 color classes. The obtained classification results were excellent for both models, with values of Recall, Specificity, Accuracy, and F-score in prediction close to 1. The proposed methodological approach can be utilized as sensor-based sorting logic in plastic recycling plants, tuning the output based on the required needs of the recycling plant, allowing to obtain a high-quality recycled HDPE of different colors, optimizing the plastic recycling process, in agreement with the principles of circular economy.

Bothrops atrox venom: Biochemical properties and cellular phenotypes of three highly toxic classes of toxins

Snake venoms have a complex mixture of compounds that are conserved across species and act synergistically, triggering severe local and systemic effects. Identification of the toxin classes that are most damaging to cell homeostasis would be a powerful approach to focus on the main activities that underpin envenomation. Here, we focus on the venom of Bothrops atrox, snake responsible for most of the accidents in Amazon region of South America. We identified the key cytotoxic toxin fractions from B. atrox venom and mapped their biochemical properties, protein composition and cell damage. Five fractions were obtained by mass exclusion chromatography and contained either a single class of enzymatic activity (i.e., L-amino acid oxidases or Hyaluronidases) or different activities co-distributed in two or more protein fractions (e.g., Metalloproteinases, Serine Proteases, or Phospholipases A2). Only three protein fractions reduced cell viability of primary human cells. Strikingly, such activity is accompanied by disruption of cell attachment to substratum and to neighbouring cells. Such strong perturbation of morphological cell features indicates likely defects in tissue integrity in vivo. Mass spectrometry identified the main classes of toxins that contribute to these phenotypes. We provide here a strategy for the selection of key cytotoxic proteins for targeted investigation of their mechanism of action and potential synergism during snakebite envenomation. Our data highlights putative toxins (or combinations of) that may be the focus of future therapeutic interference.

From Colonial India to Semi-Colonial Republican China: Imaginaries and Realities of Civil Service and State-Building in Salt Administration, 1912–45

This article studies the Sino-Foreign Salt Inspectorate, which was imposed upon a weak Chinese government by an international consortium from 1913 till 1949. The founder of the Salt Inspectorate was Sir Richard Dane, a high-level civil servant in the Indian Civil Service with long experience in salt tax administration in India. This article charts the development of the Salt Inspectorate, considering how it maintained its organisational integrity in a hostile policy environment through core strategies of simplification, bureaucratisation and insulation. The Salt Inspectorate stands as an exemplar of liberal imperial order in its replication of the Indian Civil Service and classic British liberal ideals of political economy, operating in the midst of a dangerous policy environment of civil war, rising nationalism and foreign invasion.

Creatures of Empire in Le Fanu's Uncle Silas

Abstract The interim between Darwin's first publication of the theory of natural selection (The Origin of Species, 1859) and his extended application of it to human development (The Descent of Man, 1871) corresponds with the reign of sensation fiction, a genre built upon older gothic tropes but imbricated with cultural and scientific modernization. Joseph Sheridan Le Fanu's Uncle Silas, a novel that straddles generic and national literature categories, typifies the sensation era's uneasy awareness of not only similarity but interdependence across boundaries. While eschewing typical sensation engagement with technology such as trains and telegrams, Uncle Silas reflects theories of species transmutation and particularly Darwin's Origin, which posited a malleability of seemingly distinct categories through species interaction and environmental influence. The plot of Uncle Silas centers on dislocation and efforts to fortify self-identity and reestablish security. Le Fanu's narrator-protagonist, the orphaned English or Anglo-Irish heiress Maud Ruthyn, practices bodily self-regulation and careful discernment to shore up boundaries of nationality and class that sustain her hereditary privilege. She stabilizes her class, national, and gender identity through rational revulsion from her French governess and implicitly Irish cousin. Narrator-protagonist Maud resolutely positions Englishness against foreignness and humanity against animality, but these categorical divisions, which she enforces as a character in the novel's imagined world, are exposed as false by her narration. Uncle Silas presents unregulated animal appetites as threatening to rational community governance, but it also implies that our bestial shared capacity for pain, which crosses boundaries of nationality, class, and even species, enables ethical response.

Feminism Not for All? The Discourse Around White Feminism Across Five Social Media Platforms

BIPOC scholars have criticized that feminism and feminist activism have often failed to include race, class, and intersectional identities in the feminist agenda. Using theoretical concepts from framing, rhetoric, and cross-platform activism, we examine (a) the discourse in social media posts around white feminism and (b) the platform differences of this content across five different social media platforms: Twitter, Facebook, Instagram, Reddit, and YouTube. The methodology we use is a combination of computational text analysis approaches and content analysis. Our study highlights the voice of those who felt marginalized by the feminist movement including the uprising of #MeToo. We find pockets of conversations on topics such as experiences of People of Color or Women of Color; critique of white feminism, experiences of LGBTQ+ communities, and Black experiences. These posts predominantly used techniques to persuade the audience with reason, facts, and logic. The most common framing technique used was acknowledgment. Moreover, our findings show multiple differences across the five social media platforms.

SOCIAL POLICY FOR THE MIDDLE CLASS NEEDS AND CHALLENGES IN THE LIGHT OF MEMOIRS

The authors address the issue of selected elements of the social policy offer in the context of the contemporary social challenges and changing recipients needs. They draw attention to the representatives of the middle class who, as a subject of interest for creators of social policy offer, and also as the clients of such social services, remain marginalized. By analyzing the significance of the crises (unemployment and health crisis), they recognize their consequences for the quality of life and the possibility of fulfilling the aspirations of the middle class, offering the extension of the social help offer which will not be limited to the reacting to the crucial deficits and dependency. The authors take a closer look at the identity of the middle class, discussing its values, norms and needs from the perspective of shaping the future offer of support, relevant to its needs and social costs. They point to the importance of the middle-class orientation to the success, the cult of self-sufficiency, as well as status insecurity and loosening of the social bonds for the formation of the needs and ways of satisfying them. Based on the diaries of the unemployed people and the diaries written during the COVID-19 pandemic, they analyse selected issues related to the quality of labour market services and the health care system. They address the issue of the connection of state-led social policies with the design of a new service perspective.

Лосев Алексей Фёдорович

Alexei Losev (10[22].09.1893, Novocherkassk – 24.05.1988, Moscow), Russian philosopher, philologist and writer, is the creator of a unique religious-philosophical system, which combines the reinterpreted tradition of ancient and medieval thought (Plato and Neoplatonism, Christian apophatic theology of Dionysius the Areopagite, Gregory Palamas, Nicholas of Cusa), the methodology of New European philosophy (German classical idealism, neo-Kantianism, phenomenology of E.Husserl) and the problems of New European philosophy (German classical ideal-ism, neo-Kantianism, phenomenology of E.Husserl) and the problems of Russian religious philosophy of the late 19th and early 20th centuries, from V.S. Solovyov (the idea of universalism) to P.A. Florensky. In the constructive design of Losev’s system the central place is occupied by dialectics, in the multidimensional construction of which each category and all of them together are worked out in the light of each other. Losev’s personalistic ontology is the basis of his philosophy of language (naming as an interpretative - communicative self-discovery of personality), philosophy of myth as a distinctive form of personal worldview (myth as directly experienced and created reality, symboli-cally expressed), and aesthetics (artistic form is “personality as symbol and symbol aspersonality”). Losev was the founder of the philosophy of music in Russia. His multi-volume history of ancient aesthetics represents the history of the entire ancient culture revealed in its symbolic-expressive aspects. The works of Losev, are presentative of the last generation of the Silver Age of Russian culture, became a kind of completion of Ortho-dox religious philosophy in Russia in the 19th and early 20th centuries.

Novelty Detection and Fault Diagnosis Method for Bearing Faults Based on the Hybrid Deep Autoencoder Network

In the event of mechanical equipment failure, the fault may not belong to any known category, and existing deep learning methods often misclassify such faults into a known class, leading to erroneous fault diagnosis. In order to address the challenge of identifying new types of faults in mechanical equipment fault diagnosis, this paper proposes a novelty detection and fault diagnosis method for bearing faults based on a hybrid deep autoencoder network. Firstly, a hybrid deep autoencoder network with one input and two outputs was constructed. The original data were then fed into the network to obtain its low-dimensional representation and reconstructed data. By setting a threshold based on the reconstruction error, novel class faults can be detected, while known faults can be classified based on low-dimensional features. Experimental results demonstrate that the proposed method achieves a recognition accuracy of 98.59% (100%) for novel class identification (known fault classification) on the CWRU bearing dataset, 96.79% (98.53%) on the Paderborn dataset, and 84.34% (97.03%) on the MFPT dataset. Therefore, the hybrid deep autoencoder network not only accurately detects unknown types of faults but also effectively classifies known fault types, demonstrating excellent fault identification and classification capabilities.

ID2S4FH: A Novel Framework of Intelligent Decision Support System for Fire Hazards

Modern societies and industrial sectors are serviced through storage and distribution centres (SDCs) such as supermarkets, malls, warehouses, etc. Large quantities of supplies are stocked here, e.g., food grains, clothes, shoes, pharmaceuticals, electronics, plastics, edible oils, electrical wires/equipment, petroleum products, painting materials, etc. Fires due to the burning of these materials are categorized into six classes, viz., Class A, Class B, Class C, Class D, Class K, and Class F. A fire is extinguished better when the right type of fire retardant is used. A thumb rule on firefighting also says, “never fight a fire if you do not know what is burning”. In this paper, we have proposed an Intelligent Decision Support System (ID2S4FH) to generate a real-time ‘fire-map’ of such SDCs during a fire hazard. We have interfaced six tin-oxide-based gas sensor elements, a temperature and humidity sensor, and a particulate matter (PM) sensor with microcontrollers to capture the real-time signature patterns of the ambient air. We burned sixteen different types of materials belonging to six classes of fire and created a dataset consisting of 2400 samples. The sensor array responses were then pre-processed and analysed using various classifiers trained in different analysis space domains. Among the classifiers, four classifiers achieved ‘all correct’ identification of the fire classes of 80 unknown test samples, and the lowest mean squared error (MSE) achieved was 2.81 × 10−3. During a fire hazard, our proposed ID2S4FH can generate real-time fire maps of SDCs and help firefighters to extinguish the fire using the appropriate fire retardant.

Is everyone really middle class? Social class position and identification in Alberta.

In defining social class, researchers often rely on measures of objective class position, even though subjective perceptions of social class identity can better account for the creation of social class boundaries. We explore the relationship between measures of objective class position and subjective class identity using data from an online survey of 1155 residents in Alberta, Canada, a conservative province dependent on a fluctuating energy sector. We find that although most Albertans identified as middle class, the strength of class identity and views regarding linked social class fates varied across categories with poverty class and uppermiddleclass respondents standing out. In reporting class identity, respondents considered measures related to objective class position, especially their income and economic security levels, but gaps still remained. We then use the results of this exploratory study to advocate for more comprehensive measures of social class.

Religiosity versus class existence: Indonesian Muslim middle class fashion consumption on Instagram

This study aimed to see how the consumption behavior of the Muslim middle class through the digital space is within a dualistic view, namely as a religious identity or as an affirmation of class identity. This study used the Norman Fairclough Critical Discourse Analysis (CDA) method by analyzing three aspects: text, discursive analysis, and social practice. The scope of this research analysis is the content (in the form of posts) tagged on the official Instagram accounts of three Muslim fashion brands that produce Islamic clothing, namely (Brand A), (Brand B), and (Brand C). The results suggest that middle class Muslim fashion is no longer just an aspect of religiosity and religious identity, but has become a class affirmation. Social media postings using Muslim fashion brands (both A, B, and C) and then tagging them on the brands’ official Instagram accounts shows a strengthening of class identity. Identifying Muslim fashion by tagging the brands that appear can confirm that they are able to consume Hijabs and Muslim clothing are not only used to identify symbols of religion or religiosity, but more as symbols of social class. The use of Muslim fashion is not enough except to show class identity.

Cisgender Identity Amid Figured Worlds: Toward a Close Encounter of Being a (Masque) Uline in MPSPC’s Male Dominated Course

Education takes on direction and meaning as we try to figure out who we are. So, where do we begin on our new paths to achieving our goals of educating ourselves while maintaining our identities in a school setting? Individual interviews and observations were done throughout the paper to learn how students [personally] identified as “cisgender” male students perceive the Bontoc campus atmosphere at the ROTC UNIT-MPSPC and how that climate in the Criminology Department shapes their experiences. By employing a Critical Discourse Analysis (CDA) approach that considers the ways in which sexuality, gender, class, and other identity markers intersect, this study adapted Queer Theory, Gee's (2005) analytic guidelines, and Holland, et al. Figured World Identity (FWI) category that draws particularly from exploring three Bachelor of Science in Criminology male students' constructions of being cisgender that shaped their criminology careers. Rather than viewing identity through a singular lens, the term identity displays how manifold characteristics of one’s identity comes together to form one’s complete (gender) identity, conveying concurrently the mechanisms and the whole.

Clustering based background learning for hyperspectral anomaly detection

In real hyperspectral images, which have a complex background with multiple classes, separation of anomalous targets from background is a challenging problem. The Clustering based Background Learning (CBL) method is proposed for hyperspectral anomaly detection in this paper to deal with this difficulty. The proposed CBL method identifies the background classes, and so facilitates detection of the anomalies. CBL is built based on this reality that anomalies comprise a limited number of pixels occupying small areas. To achieve anomalies, the spectral and spatial clustering maps are fused through a new method called Multiplicative Fusion (MF). This fusion method leverages both spectral and spatial information and makes the clustering results to support each other for anomalies detection. The synergy done in the clustering phase followed by applying an adaptive support vector machine leads to identification of various background classes. One important advantage of the CBL method is its generalization ability for anomaly detection in various sub regions of a large scene where the trained model for a sub region can be used for anomaly detection of other sub regions of the same scene. Additionally, the pre-processing and the model training steps can be performed on a common hardware without any requirement to expensive hardware for high processing power. The experimental results demonstrate that the CBL method outperforms the competing methods on various types of hyperspectral data with different spectral and spatial resolutions where a stable behaviour can be seen in detection performance of CBL on different images.

Practicing and Managing Foreign Toponyms in China: Cultural Politics and Ideologies

This study examines the vogue of adopting foreign-origin place names in Chinese cities and the Chinese governments’ endeavors to regulate the toponymic landscape. The place naming practices, management, and public attitudes concerning foreign toponyms are analyzed to reveal the cultural politics and ideologies of place naming in China’s context. It is found that the foreign toponyms emplaced in urban space mostly have Western origins or roots, and their profusion is largely attributed to their associated symbolic capital, and the clientele’s taste and class identity. In the rectification process, Chinese governments at different levels constructed themselves as protectors of traditional Chinese culture and guards against xenophilia, thus enhancing their symbolic power and governing legitimacy. The general public has resisted top-down toponymic planning via acts of citizenship to reclaim the rights of naming and owning public space. Our findings suggest that nowadays, even in highly regulated societies like China, it would be hard to achieve the expected planning goals when governments simply resort to hegemonic power to implement the place (re)naming policies.

On 2r-ideals in commutative rings with zero-divisors

Abstract In this article, we are interested in uniformly p r pr -ideals with order ≤ 2 \le 2 (which we call 2 r 2r -ideals) introduced by Rabia Üregen in [On uniformly pr-ideals in commutative rings, Turkish J. Math. 43 (2019), no. 4, 18781886]. Several characterizations and properties of these ideals are given. Moreover, the comparison between the (nonzero) 2 r 2r -ideals and certain classes of classical ideals gives rise to characterizations of certain rings based only on the properties of the ideals consisting only of zero-divisors. Namely, among other things, we compare the class of (nonzero) 2 r 2r -ideals with the class of (minimal) prime ideals, the class of minimal prime ideals and their squares, and the class of primary ideals. The study of 2 r 2r -ideal in polynomial rings allows us to give a new characterization of the rings satisfying the famous A A -property.
