description: [Objectives] To comprehensively and deeply explore the effects of different land cover types in the lower reaches of Niyang River on soil microbial biomass carbon and nitrogen, and to provide a scientific basis for the rational use and sustainable management of land resources in this area. [Methods] Taking the 3 types of land cover (cultivated land, grass land and forest land) in the lower reaches of Niyang River in Tibet as the research object, the contents, distribution characteristics and relationships of soil organic carbon, organic nitrogen, microbial biomass carbon, microbial biomass nitrogen and readily oxidizable organic carbon, and their relationships were studied in 0-10, 10-20, 20-40, 40-60, and 60-100 cm soil depth. [Results] The soil organic carbon content of forest land was higher than that of grass land and cultivated land; the vertical change trend of soil organic carbon content decreased with the increase of depth (P<0.05), and it was mainly concentrated in the soil with a depth of 0-20 cm. The soil organic carbon content was significantly different among forest land, grass land and cultivated land (P<0.05), but there was no significant difference between cultivated land and grass land (P>0.05). The soil organic nitrogen content was significantly different among cultivated land, grass land, and forest land (P<0.05), but there was no significant difference between grass land and forest land (P>0.05). The readily oxidizable organic carbon, microbial biomass carbon and nitrogen in forest land were higher than that in cultivated land and grass land. The change trend of soil readily oxidizable organic carbon, microbial biomass carbon and microbial biomass nitrogen was similar to the change of soil organic carbon content, showing a significant positive correlation. In addition to being subject to land cover, soil microbial biomass carbon and nitrogen content were also subject to the interaction of factors such as soil temperature, humidity, pH and vegetation types. [Conclusions] Changes in land cover significantly affect soil organic carbon and nitrogen, readily oxidizable organic carbon, microbial biomass carbon and nitrogen content.

description: [Objectives] To investigate the removal effect of nitrifying bacteria on ammonia nitrogen in water. [Methods] In this experiment, the treated water (referred to as raw water hereinafter) from the Changping Town Qiaoli Water Treatment Project in Dongguan City of Guangdong Province was used as the experimental water body, and the nitrifying bacteria liquid used in the project was taken as the experimental material, to explore the removal effect of the nitrifying bacteria liquid on the ammonia nitrogen in the water body. [Results] Under the condition that other variables remain unchanged, the more the amount of nitrifying bacteria liquid added, the higher the removal efficiency of nitrifying bacteria liquid; under the same conditions, the removal effect of ammonia nitrogen in a stirred water body is better than that in an unstirred water body; the removal effect of ammonia nitrogen in a water body with bio-media/carriers is better than that without bio-media/carriers. [Conclusions] Nitrifying bacteria have a better removal effect on the ammonia nitrogen in the water body.

description: Erdős conjectured that for any set $A\subseteq \mathbb{N}$ with positive lower asymptotic density, there are infinite sets $B,C\subseteq \mathbb{N}$ such that $B+C\subseteq A$. We verify Erdős' conjecture in the case that $A$ has Banach density exceeding $\frac{1}{2}$. As a consequence, we prove that, for $A\subseteq \mathbb{N}$ with positive Banach density (a much weaker assumption than positive lower density), we can find infinite $B,C\subseteq \mathbb{N}$ such that $B+C$ is contained in the union of $A$ and a translate of $A$. Both of the aforementioned results are generalized to arbitrary countable amenable groups. We also provide a positive solution to Erdős' conjecture for subsets of the natural numbers that are pseudorandom.

A Reputation-Centered Theory of Human Cooperation and Social Organization
Creators: name: Takács, Károly
Publisher: name: Sociologica
Year: 2022

description: While all species are unique, only humans have been able to develop complex tools and technology, and to place energy and their environment under control. Social learning and extrasomatic storage of information enabled rapid development in recent evolutionary times. Our argument is that human uniqueness lies in human sociality. Namely, large-scale and widespread cooperation, the establishment and maintenance of social order, the use of language as a communication tool, advanced social cognition, and large social complexity built on social norms are characteristics of unique human sociality. Here we claim that reputation is a human invention that could have largely contributed to the development of these characteristics. Reputation-based mechanisms are fundamental to the emergence and maintenance of large-scale cooperation between non-closely related individuals by informing partner selection and conditional actions towards others. Reputation is the basis of informal social hierarchies that provide a guideline to maintain social order. Reputation concerns and gossip about absent others constitute a large part of human communication. This way, and with increased abilities of social cognition, we keep account of a larger set of individuals, and can be directed by norms that guide proper behavior and regulate interactions towards norm violators and their punishers. To provide a nuanced view on how reputation became key to all social features of human uniqueness, we consider its roles and dimensions starting from individual life and going towards interdependencies in dyads, small groups, intergroup relations, and large-scale societies. Throughout this journey from individual to societal life, we speculate that reputation has reached its central importance in small group life and not at a lower or higher level of complexity.

description: Recent developments in machine learning engendered many algorithms designed to solve diverse problems in countless scientific areas, particularly recognition structures such as speech recognition, text recognition, image recognition. In image recognition tasks, the experiments within limited computing and time constraints are challenging issue. In this paper, we have recognized different types of bird's images and performance analysis of machine learning algorithms. Basic assembly of support vector machine, k-nearest neighbors, random forest and logistic regression are modified for experiments by defining relationships and adjusting different parameters. We have collected 3490 images of 22 types of bird's and created our dataset and the dataset is adopted to extract the features and the algorithms are employed for recognition of the different types of bird's images. The experimental results are discussed in terms of accuracy, Precision, recall and F1 score. While, the support vector machine better preforms as compared to the other three methodologies, whereas, KNN, RF and LR achieved more interesting results.

Reputation Traps
Creators: name: Wittek, Rafael
Publisher: name: Sociologica
Year: 2022

description: Reputations and the related social processes of evaluation are increasingly hailed as one of the most promising mechanisms sustaining cooperation in a variety of mixed-motive settings, ranging from neighborhood communities and formal organizations to online markets. But if reputation is such a powerful route to sustain cooperation, why do we then see cooperation breaking down so frequently? The present essay argues that such reputation failures should be conceived as part of a broader set of governance traps as they result from institutional designs that are based on misconceived assumptions about human nature. My argument comes in five steps. Using a social rationality approach, I first outline the contours of an alternative explanatory framework. Distinguishing between two types of managerial control philosophies (rational vs. normative) and two forms of control (bureaucratic vs. collegial) I then review the four major theoretical templates that currently inform the design of institutions and organizational governance structures: agency, stewardship, reputation, and social identity theory. Drawing on available empirical evidence, I subsequently describe how each of these design principles may trigger vicious cycles of cooperation decay. I refer to these processes as incentive, reputation, empowerment and identity traps. I contend that the common denominator behind each of these sustainability traps is that the structures in place fail to support the normative frame required to sustain joint production motivation. I then present findings from selected empirical studies showing how specific relational support structures may prevent the emergence of these sustainability traps, or mitigate their consequences. The essay concludes with a discussion of implications for future research on cooperation.

description: Heisenberg's uncertainty principle is quantified by error-disturbance tradeoff relations, which have been tested experimentally in various scenarios. Here we shall report improved new versions of various error-disturbance tradeoff relations by decomposing the measurement errors into two different components, namely, operator bias and fuzziness. Our improved uncertainty relations reveal the tradeoffs between these two components of errors, and imply various conditionally valid error-tradeoff relations for the unbiased and projective measurements. We also design a quantum circuit to measure the two components of the error and disturbance.

description: A model of shear thickening in dense suspensions of Brownian soft sphere colloidal particles is established. It suggests that shear thickening in soft sphere suspensions can be interpreted as a shear induced phase transition. Based on a Landau model of the coagulation transition of stabilized colloidal particles, taking the coupling between order parameter fluctuations and the local strain-field into account, the model suggests the occurrence of clusters of coagulated particles (subcritical bubbles) by applying a continuous shear perturbation.The critical shear stress of shear thickening in soft sphere suspensions is derived while reversible shear thickening and irreversible shear thickening have the same origin. The comparison of the theory with an experimental investigation of electrically stabilized colloidal suspensions confirms the presented approach.

Period Stain and Social Evaluation. The Performance of Shame
Creators: name: Sabido Ramos, Olga
Publisher: name: Sociologica
Year: 2022

description: The "period stain" could be considered as a symbolic and material object with strong moral overtones. In this article, I propose to analyze it from the research program of gossip and reputation (Giardini & Wittek, 2019a) in dialogue with the intersection between Simmel’s and Goffman’s relational sociology on one side, and feminists’ theories from the other. I will give an account of the meanings attributed to body information, such as the staining of clothes with menstrual blood and the impact on the social evaluation of bodies from a woman's point of view. To achieve this, I analyze the results of an instrument applied in March 2021 entitled Virtual survey on the experience of menstruation in the context of the pandemic caused by Covid-19. Although women do not share the gender stereotypes associated with menstruation, they reveal the negative impact these stereotypes had on the social evaluation of this bodily experience. Women are concerned about the negative evaluation that others have of the experience of the period stain. I will show how the performance of shame associated with period stain is narrated; and, how mockery is an affective device of reputation. However, there are also ways to re-signify the experience based on solidarity among friends.

description: The anisotropic antiferromagnetic Ising model on the fractal Sierpiński gasket is intensively studied, and a number of exotic properties are disclosed. The ground state phase diagram in the plane of magnetic field-interaction of the system is obtained. The thermodynamic properties of the three plateau phases are probed by exploring the temperature-dependence of magnetization, specific heat, susceptibility and spin-spin correlations. No phase transitions are observed in this model. In the absence of a magnetic field, the unusual temperature dependence of the spin correlation length is obtained with $0 \leq$J$_b/$J$_a<1$, and an interesting crossover behavior between different phases at J$_b/$J$_a=1$ is unveiled, whose dynamics can be described by the J$_b/$J$_a$-dependence of the specific heat, susceptibility and spin correlation functions. The exotic spin-spin correlation patterns that share the same special rotational symmetry as that of the Sierpiński gasket are obtained in both the $1/3$ plateau disordered phase and the $5/9$ plateau partially ordered ferrimagnetic phase. Moreover, a quantum scheme is formulated to study the thermodynamics of the fractal Sierpiński gasket with Heisenberg interactions. We find that the unusual temperature dependence of the correlation length remains intact in a small quantum fluctuation.

Tarnished Nationalism. Rehabilitating Serbia’s Reputation on the World Stage
Creators: name: Brandt, Emma E.S.
name: Fine, Gary Alan
Publisher: name: Sociologica
Year: 2022

description: Reputation management is a concern not just for individuals and organizations, but for nation states. Rehabilitating a tarnished reputation is part of the attempt by national entrepreneurs to create images that build “soft power;” a form of cultural authority. This is a concern especially for smaller nations that lack “hard power” through the dominance of their economy or military. We investigate how governmental actors and leading societal institutions attempt to rehabilitate a country’s image. In doing so, we present the case of contemporary Serbia, which acquired a negative international reputation resulting from not just the Yugoslav Wars of the 1990s, but also from long legacies of racialization via discourses of Orientalism and “Balkanism” in Western perceptions of Southeastern Europe. Unlike its neighbor, Croatia, Serbia is not a European Union member and lacks a seacoast with which to attract tourists. As a result, it must gain positive international attention in other ways. Through the examples of promoting sports successes (in basketball and tennis), “pinkwashing” or highlighting symbolic LGBT integration (while perhaps lacking day-to-day integration), becoming a popular nightlife destination, welcoming refugees as a stop on the “Balkan route,” and, most recently, deploying efforts at Covid-19 “vaccine diplomacy,” we consider the challenges to Serbia’s attempt to rehabilitate its difficult reputation. Not only is the country’s international standing a matter of profound concern to its inhabitants — having economic, political, and symbolic impacts — but Serbia is an archetypal case to understand the perception of “problematic” nations on the world stage.

description: Fe$_{1+y}$Te with $y \lesssim 0.05$ exhibits a first-order phase transition on cooling to a state with a lowered structural symmetry, bicollinear antiferromagnetic order, and metallic conductivity, $dρ/dT > 0$. Here, we study samples with $y = 0.09(1)$, where the frustration effects of the interstitial Fe decouple different orders, leading to a sequence of transitions. While the lattice distortion is closely followed by \emph{incommensurate} magnetic order, the development of \emph{bicollinear} order and metallic electronic coherence is uniquely associated with a separate hysteretic first-order transition, at a markedly lower temperature, to a phase with dramatically enhanced bond-order wave (BOW) order. The BOW state suggests ferro-orbital ordering, where electronic delocalization in ferromagnetic zigzag chains decreases local spin and results in metallic transport.

Sociology’s Stake in Data Science

Publisher: name: Sociologica
Year: 2022

description: Data scientists gave sociologists pause when they started disturbing social life and research. This article considers three instances where data science made inroads into the sociology jurisdiction. Instead of calling for a defense, they reveal opportunities for sociological research in the digital age. These opportunities build on the data-analytic thinking that undergirds the discipline's more salient structures and conventions. They recall old sociological intuitions and pragmatist theory that conceptualize the research process in a way that leaves room for novel observations. From this perspective, data science can help integrate sociology around new problems and shared principles and enlarge it by introducing its ideas to different audiences.

description: We present and study cosmic voids identified using the watershed void finder VIDE in the Sloan Digital Sky Survey Data Release 9, compare these voids to ones identified in mock catalogs, and assess the impact of the survey mask on void statistics such as number functions, ellipticity distributions, and radial density profiles. The nearly 1,000 identified voids span three nearly volume-limited samples from redshift z = 0.43 to 0.7. For comparison we use 98 of the publicly available 2LPT-based mock galaxy catalogs of Manera et al., and also generate our own mock catalogs by applying a Halo Occupation Distribution model to an N-body simulation. We find that the mask reduces the number density of voids at all scales by a factor of three and slightly skews the relative size distributions. This engenders an increase in the mean ellipticity by roughly 30%. However, we find that radial density profiles are largely robust to the effects of the mask. We see excellent agreement between the data and both mock catalogs, and find no tension between the observed void properties and the properties derived from ΛCDM simulations. We have added the void catalogs from both data and mock galaxy populations discussed in this work to the Public Cosmic Void Catalog at http://www.cosmicvoids.net.

The Neoliberal Asylum. The Ausbildungsduldung in Germany: Rejected Asylum-Seekers Put to Work between Control and Integration
Creators: name: Fontanari, Elena
Publisher: name: Sociologica
Year: 2022

description: This paper discusses the regulation of the Ausbildungsduldung implemented in Germany in 2016 to integrate rejected asylum-seekers through vocational training into the labour market. I here intertwine the literature of neoliberal welfare state with the theories of border studies to understand the intersectionality of race and class in the lives of refugees put to work. Drawn on ethnographic fieldwork from 2016 to 2020 with refugees and practitioners, I shed light on a moral economy of deservingness underpinning the Ausbildungsduldung and affecting its implementation as well as the process of construction of the self negotiated by refugees during the vocational training. The analysis of the discursive, formal, and subjective dimensions of the Ausbildungsduldung shows how the control feature prevails over the integration aim. This pushes refugees into a legal, social-economic, and existential precarity that is institutionally produced. To be integrated, refugees have to prove their worthiness by embodying the ideal migrant: a good worker with a "Beruf" (profession) in the low-paid sectors of the German economy. Ultimately, this paper addresses the concept of "Neoliberal Asylum" to discuss how the Western states use the category of "deservingness" as moral criteria to guide the juridical measures to govern refugees through their economies.

description: In this work, we complete the calculation of the soft part of the two-loop integrated jet thrust distribution in e+e- annihilation. This jet mass observable is based on the thrust cone jet algorithm, which involves a veto scale for out-of-jet radiation. The previously uncomputed part of our result depends in a complicated way on the jet cone size, r, and at intermediate stages of the calculation we actually encounter a new class of multiple polylogarithms. We employ an extension of the coproduct calculus to systematically exploit functional relations and represent our results concisely. In contrast to the individual contributions, the sum of all global terms can be expressed in terms of classical polylogarithms. Our explicit two-loop calculation enables us to clarify the small r picture discussed in earlier work. In particular, we show that the resummation of the logarithms of r that appear in the previously uncomputed part of the two-loop integrated jet thrust distribution is inextricably linked to the resummation of the non-global logarithms. Furthermore, we find that the logarithms of r which cannot be absorbed into the non-global logarithms in the way advocated in earlier work have coefficients fixed by the two-loop cusp anomalous dimension. We also show that, given appropriate L-loop contributions to the integrated hemisphere soft function, one can straightforwardly predict a number of potentially large logarithmic contributions at L loops not controlled by the factorization theorem for jet thrust.

description: The evolution of the large scale distribution of matter in the universe is often characterized by the density field. Here we take a complimentary approach and characterize it using the cosmic velocity field, specifically the deformation of the velocity field. The deformation tensor is decomposed into its symmetric component (known as the "shear tensor") and its anti-symmetric part (the "vorticity"). Using a high resolution cosmological simulation we examine the relative orientations of the shear and the vorticity as a function of spatial scale and redshift. The shear is found to be remarkable stable to the choice of scale, while the vorticity is found to quickly decay with increasing spatial scale or redshift. The vorticity emerges out of the linear regime randomly oriented with respect to the shear eigenvectors. Non-linear evolution drives the vorticity to lie within the plane defined by the eigenvector of the fastest collapse. Within that plane the vorticity first gets aligned with the middle eigenvector and then it moves to be preferentially aligned with the third eigenvector, of slowest collapse. Finally a scale of "non-linearity" to be used when calculating properties of the non-linear deformation tensor at different redshifts is suggested.

[Results] Under the film mulching condition, the SOC, LOC and CMI of the single application of chemical fertilizer cultivation mode were lower than the open field control. CHE, CHA and CFA increased with the increase of planting years, but the degree of increase was generally less than that of the open field control. With the increase of planting years, by 2020, the soil LOC/SOC value of film mulching decreased by 4.97% compared with before the start of the experiment, while the open field control increased by 1.11%; the organic carbon oxidation stability coefficient (KOS) of the film mulching was higher than that of the open field control; the soil CHA/CFA value and PQ value were higher than that of the open field control. [Conclusions] Under the condition of single application of chemical fertilizers, the continuous film mulching cultivation mode reduces the soil carbon fixation capacity, and soil organic carbon tends to be stable, which is not conducive to biological utilization and could reduce the soil fertility and degrade the soil quality, causing adverse effects on the stability of crop yield and sustainable production in the long run.
Children’s Perceptions of Social Status Studying the Effects of Non- Direct Verbal Communication and Direct Non-Verbal Communication on Children’s Perception of Social Status
Creators: name: Hamlette, David
Publisher: name: University of Chicago

description: Current research has been focused on the effects of social cues, and how individuals use all different types of stimuli to form attitudes about themselves, members of their group, and those that they consider outside their group. However, there is little research focused on understanding the developmental thresholds in children around nonverbal cues, specifically at what age are they able to recognize them, as well as if they possess the ability to use nonverbal cues to infer other factors of social status and hierarchy. In this study we attempt to begin addressing that question by testing out a sample group of adults (n = 96) to view a video of a teacher giving direction to students and using non directive language paired with directive nonverbal communication. This study was interested in testing our methodology so that it could be tailored to younger children, as well as understand how successful people were at picking up on nonverbal social cues, and if/ how much they used them to make social inferences around ability and social status. Results from this study showed that there were significant effects and that people were not only able to recognize large amounts of nonverbal cues, but were also able to utilize those cues to create social rankings and modify those rankings based on new novel additions. Future research aims to utilize this methodology on children and test their thresholds for nonverbal cues and levels of social based inferencing abilities

description: [Objectives] The paper was to understand the health of rural poor population in Chongqing, and to put forward countermeasures for health poverty alleviation. [Methods] The 439 people living in poverty in Qianjiang District and Pengshui County, Chongqing, were investigated on the spot to deeply understand and analyze the health status, current medical insurance status and accuracy of medical system of rural poor population in Chongqing. [Results] The vast majority of poor households had been lifted out of poverty after targeted poverty alleviation. Poverty due to illness was the main cause of family poverty. The prevalence of chronic diseases in poor households was high, and the overall health level showed a downward trend. The countermeasures and suggestions for strengthening the construction of medical insurance system, exploring and perfecting rural medical assistance system, enhancing the service capacity of primary medical and health institutions, and strengthening health education and health management were put forward. [Conclusions] The study provides an empirical evidence for improving the health level of poor rural residents and promoting targeted health poverty alleviation policies.

description: The eco-environmental damage compensation system is not only an important part of the central government's Overall Plan for the Reform of Ecological Civilization System and special plan, but also a blank point and weak link in the construction of eco-environmental protection system. From the construction of ecological civilization system, the fragility of ecological environment and the history of past damage, the comparative analysis of relevant laws and regulations, and the connotation of the concept of ecological environment, this paper expounds the importance, urgency and necessity of the reform of eco-environmental damage compensation system and the technical complexity of damage compensation judgment. In accordance with the local legislation and practical cases in the reform of eco-environmental damage compensation system in Shaanxi Province, this paper puts forward legislative and policy suggestions to accelerate the reform of eco-environmental damage compensation system.
Ice quivers with potentials associated with triangulations and Cohen-Macaulay modules over orders

description: Given a triangulation of a polygon P with n vertices, we associate an ice quiver with potential such that the associated Jacobian algebra has the structure of a Gorenstein tiled K[x]-order L. Then we show that the stable category of the category of Cohen-Macaulay L-modules is equivalent to the cluster category C of Dynkin type A(n-3). It gives a natural interpretation of the usual indexation of cluster tilting objects of C by triangulations of P. Moreover, it extends naturally the triangulated categorification by C of the cluster algebra of type A(n-3) to an exact categorification by adding coefficients corresponding to the sides of P. Finally, we lift the previous equivalence of categories to an equivalence between the stable category of graded Cohen-Macaulay L-modules and the bounded derived category of modules over a quiver of type A(n-3).

To Read or Not to Read: Risk and Literacy for Enslaved Americans
Creators: name: Ortiz, P. Henry
Publisher: name: University of Chicago
Year: 2022
Subjects: subject: Slave literacy
subject: American slavery

description: When antebellum slaveholders opposed slave literacy, it was primarily because they thought readers and slaves had opposing characteristics. Through lectures, threats, and commands about literacy, slaveholders conveyed that sentiment to enslaved people. Consequently, enslaved people usually concluded that pursuing literacy was too risky, leading most of them to not pursue literacy. But sometimes enslaved people became passionate about acquiring literacy and tenaciously pursued the skill. Pursuing literacy was a tradeoff: it increased enslaved people's chances of acquiring literacy, but also their chances of getting whipped. Enslaved people who pursued literacy usually did not get whipped, likely because relatively few pursued literacy and because getting help from a white was the most common way enslaved people pursued literacy. Because literacy was only of tenuous value for someone in the position of an American slave, enslaved people were smart to favor caution about pursuing literacy.

description: We study submanifolds of A_g that are totally geodesic for the locally symmetric metric and which are contained in the closure of the Jacobian locus but not in its boundary. In the first section we recall a formula for the second fundamental form of the period map due to Pirola, Tortora and the first author. We show that this result can be stated quite neatly using a line bundle over the product of the curve with itself. We give an upper bound for the dimension of a germ of a totally geodesic submanifold passing through [C] in M_g in terms of the gonality of C. This yields an upper bound for the dimension of a germ of a totally geodesic submanifold contained in the Jacobian locus, which only depends on the genus. We also study the submanifolds of A_g obtained from cyclic covers of the projective line. These have been studied by various authors. Moonen determined which of them are Shimura varieties using deep results in positive characteristic. Using our methods we show that many of the submanifolds which are not Shimura varieties are not even totally geodesic.

description: [Objectives] To explore a rapid detection method of sweet cherry fruits in natural environment. [Methods] The cutting-edge YOLOv4 deep learning model was used. The YOLOv4 detection model was built on the CSP Darknet5 framework. A mosaic data enhancement method was used to expand the image dataset, and the model was processed to facilitate the detection of three different occlusion situations: no occlusion, branch and leaf occlusion, and fruit overlap occlusion, and the detection of sweet cherry fruits with different fruit numbers. [Results] In the three occlusion cases, the mean average precision (mAP) of the YOLOv4 algorithm was 95.40%, 95.23%, and 92.73%, respectively. Different numbers of sweet cherry fruits were detected and identified, and the average value of mAP was 81.00%. To verify the detection performance of the YOLOv4 model for sweet cherry fruits, the model was compared with YOLOv3, SSD, and Faster-RCNN. The mAP of the YOLOv4 model was 90.89% and the detection speed was 22.86 f/s. The mAP was 0.66%, 1.97%, and 12.46% higher than those of the other three algorithms. The detection speed met the actual production needs. [Conclusions] The YOLOv4 model is valuable for picking and identifying sweet cherry fruits.
