We axiomatise the algebraic properties of toroidal compactifications of (mixed) Shimura varieties and their automorphic vector bundles. A notion of generalised automorphic sheaf is proposed which includes sheaves of (meromorphic) sections of automorphic vector bundles with prescribed vanishing and pole orders along strata in the compactification, and their quotients. These include, for instance, sheaves of Jacobi forms and weakly holomorphic modular forms. Using this machinery, we give a short and purely algebraic proof of the proportionality theorem of Hirzebruch and Mumford.

Human activity recognition (HAR) is an emerging challenge among researchers. HAR has many possible uses in various fields, including healthcare, sports, and security. Furthermore, there are only a few publicly accessible datasets for classifying and recognizing physical activity in the literature, and these datasets comprise fewer activities. We created and compared our dataset with available datasets, that is, NTU-RGBD, UP-FALL, UR-Fall, WISDM, and UCI HAR. The proposed dataset consists of seven activities: eating, exercise, handshake, situps, vomiting, headache, and walking. The activities were collected from 20 people between the ages of 25 and 40 years using Kinect V2 sensor at 30 FPS. For classification, we use deep learning architectures based on convolutional neural network (CNN) and long short-term memory (LSTM). Additionally, we developed a novel hybrid deep learning model by combining a CNN, a bidirectional LSTM unit, and a fully connected layer for activity identification. The suggested model builds unique guided features using the preprocessed skeleton coordinates and their distinctive geometrical and kinematic aspects. Results from the experiment are contrasted with the performance of stand-alone CNNs, LSTMs, and ConvLSTM. The proposed model’s accuracy of 99.5% surpasses that of CNN, LSTM, and ConvLSTM, which have accuracy rates of 95.76%, 97%, and 98.89%, respectively. Our proposed technique is invariant of stance, speed, individual, clothes, etc. The proposed dataset sample is accessible to the general public.

Teenagers often present in crisis with risk issues, mainly risk to self but sometimes risk to others. Adolescent violence is commonplace and is not just the remit of adolescent forensic psychiatry. Clinicians may lack confidence assessing risk of violence and can neglect vital areas that are essential to reduce risk. Use of structured violence risk assessments enables the multi-agency professional network to formulate a young person's presentation and their violence in a holistic way and consequently develop targeted risk management plans addressing areas such as supervision, interventions and case management to reduce the risk of future violence. Of the several validated tools developed for young people, the Structured Assessment of Violence Risk – Youth (SAVRY™) is that most used by UK-based forensic adolescent clinicians. This article outlines the epidemiology, causes and purposes of violence among adolescents; discusses types of risk assessment tool; explores and deconstructs the SAVRY; and presents a fictitious risk formulation.

Previous literature attempted to gain insight into financial abuse involving people with dementia by analysing court cases, but these studies were limited in sample size or scope. This study collected 214 court rulings directly related to the financial decisions of people with dementia to identify characteristics of the financial abuse victim, perpetrators and the types of assets. The models of bystander intervention and routine activity theory were used as conceptual models to guide analysis regarding the role of bank staff as well as the court's decision in cases of financial abuse. The majority of financial abuse perpetrators were family members (73.8%), as opposed to outsiders (19.2%). Transfer of real estate was the most common legal issue, and land was the most common financial asset involved. Difficult intra-family relationships seem to pose a great risk of financial abuse involving people with dementia since adult children were found to be the most likely perpetrators (52.7%) but also plaintiffs accusing financial abuse (57.6%). In accordance with the bystander intervention model, bank staff were more likely to be suspicious of financial abuse when an outsider was regarded as the perpetrator. In accordance with the routine activity theory model, the court was more likely to acknowledge the case as an invalid financial decision when an outsider was regarded as the perpetrator in financial abuse cases. Since people with dementia suffer from greater losses due to their family members, future policies should establish guidelines for front-line bank staff to identify warning signs to reduce the risk of financial abuse involving people with dementia, not only to prevent fraud by outsiders but also exploitation by family members.

A weighted nonlinear flag is a nested set of closed submanifolds, each submanifold endowed with a volume density. We study the geometry of Fréchet manifolds of weighted nonlinear flags, in this way generalizing the weighted nonlinear Grassmannians. When the ambient manifold is symplectic, we use these nonlinear flags to describe a class of coadjoint orbits of the group of Hamiltonian diffeomorphisms, orbits that consist of weighted isotropic nonlinear flags.

Many scholars have used local Chinese county gazetteers for historical and socioeconomic analyses, yet little research has examined the completeness of coverage or the biases in reporting that characterize the compilation of these gazetteers. In this paper, we provide a novel source for studying Chinese political movements and local history under the communist regime after 1949: the internal-discussion drafts of county gazetteers (xianzhi pingyigao). Our findings constitute the first study to use internal review drafts to examine the authenticity and credibility of county gazetteers. Prior to their publication, gazetteer drafts are compiled by a team of editors and typically receive at least three rounds of rigorous internal review. These internal-discussion drafts are subject to a prolonged and strict process of self and external censorship. Our analysis engages in a close comparison of text samples extracted from two versions of local gazetteers collected from four counties in Guangxi province. Compared to the draft versions, we find evidence of serious data manipulation and a tendency to underreport historical events in the published editions. Our research evidently demonstrates the process of historiography editing and reveals how local history is presented through the lens of government public documents in China.

This article weighs the meaning, potential, and pitfalls of the concept of “racial capitalism” for studying the nexus of racial division and the economy. The concept has spread like wildfire in Anglophone social science since its≠ introduction in Cedric Robinson’s revisionist account of the rise of capitalism as racializing, but it remains epistemically inchoate and analytically problematic. The critique of leading uses and common corollaries of the term shows that it stipulates that which needs to be explicated, namely, the “articulation” of capitalism “through race,” which is not a structural invariant but ranges from coevalness and synergy to parasitism and disconnection. The notion cannot accommodate the varied bases of race as a naturalizing and hierarchizing principle of vision and division as well as the historical peculiarity of the economic variant of slavery in the Atlantic world. Advocates of “racial capitalism” need to put in the hard work of epistemological elucidation, logical clarification, and historical elaboration needed if they are to make the label more than a “conceptual speculative bubble.”

This article investigates the impact of male migration on left-behind women in nineteenth-century Chongqing, focusing on the intersection among gender, migration, and religion. It analyze the unintended consequences of failed male migration, in which the husband's failure to send regular remittances was prone to cause tremendous anxiety and financial difficulties for his wife. In the absence of strong male-centered kinship organizations, Chongqingese women exploited unorthodox options to support themselves. Buddhist monasticism proved appealing because it provided both a stable source of livelihood and an inclusive all-female space. However, female renunciation was controversial because it challenged state-sponsored patriarchal values. Returned husbands enlisted the state's help in revoking their wives' religious decisions. Paradoxically, for vulnerable women like concubines, nunhood proved an attractive option because it helped them obtain migration-triggered divorces on favorable terms. They strategically synergized the bodily practice of monastic celibacy with the discourse of female chastity to assure their estranged spouses of lifelong commitments to non-remarriage. By doing so, these women succeeded in receiving generous financial compensation. This study highlights how the combination of religion and translocality enabled women to renegotiate their positionality within the patriarchy.

Conventional wisdom claims that racial diversity undermines public goods provision. I show that class-based differences, instead, incentivize cooperation for public goods. Class-based segregation reduces spatial externalities of inequality (e.g., sewage pollution and crime) spilling over from impoverished areas (e.g., slums) to the middle class. Conversely, I argue that in integrated (de-segregated) cities, the scale of such externalities undermines the efficacy of private services (e.g., private security), thereby inducing middle-class preferences for externalities-correcting public goods. Thus, while segregation polarizes preferences, integration aligns the middle class with the poor in coalitions that support public goods over private alternatives. I illustrate the theory using focus groups, a proposed quasi-experimental strategy, and an original face-to-face survey of 4,208 households across 420 neighborhoods in São Paulo, Brazil. The analysis introduces self-interest in reducing intergroup externalities as a mechanism for cooperation for public goods even in diverse societies. Using mechanism vignettes, I distinguish the mechanism from the affective attitudes—racial tolerance, social affinity—of intergroup contact.

In response to two pieces I wrote in the 1990s, and a section of my book Cultural History of the Atlantic World (2012), David Geggus has charged me with fomenting “Kongomania.” I am a specialist in the history of the Kingdom of Kongo, it is true, and in both pieces, Kongo's history was an important part of the argument. In spite of my own fondness for Kongo and its role in the world, I plead not guilty.

The cotton bollworm, Helicoverpa armigera (Hünber) (Lepidoptera: Noctuidae), is a polyphagous pest that causes severe damage to economical crops in most parts of the world. The juvenile hormone analogues are a group of insect growth regulators that increase larval ages and disrupt larval development. Moreover, they affect reproductive system in adult insects. In this study, the effects of sublethal doses of fenoxycarb on fecundity, fertility, and longevity parameters, as well as on oocyte size, ecdysteroid titer in ovaries, and expression level of the ultraspiracle (USP), ecdysone receptor (EcR), hormone receptor 3 (HR3), and vitellogenin (Vg) genes in adult female H. armigera, were examined. Feeding on artificial diet containing fenoxycarb (LC10 and LC25) significantly decreased the percentage of larval survival rate, pupation rate, pupal weight, fecundity, fertility, and oviposition period. It also clearly shortened female longevity. Fenoxycarb treatment suppressed the expression of the USP, EcR, and Vg genes in H. armigera but had no effect on the HR3 gene expression level in either pupae or adults. Overall, our results show that using fenoxycarb as a juvenile hormone analogue can reduce reproduction in H. armigera and may work as an alternative to the use of insecticides for controlling this important agricultural pest.

Extensive research investigates the impact of descriptive representation on women’s political participation; yet, the underlying mechanisms remain unclear. This article develops a novel theory of descriptive representation, arguing that women politicians mobilize women’s political participation by recruiting women as grassroots party activists. Evidence from a citizen survey and the natural experiment of gender quotas in India confirm that women politicians are more likely to recruit women party activists, and citizens report greater contact with them in reserved constituencies during elections. Furthermore, with women party activists at the helm, electoral campaigns are more likely to contact women, and activist contact is positively associated with political knowledge and participation. Evidence from representative surveys of politicians and party activists and fieldwork in campaigns, further support the theory. The findings highlight the pivotal role of women’s party activism in shaping women’s political behavior, especially in contexts with pervasive clientelism and persistent gender unequal norms.
