Recovering height information from a single aerial image is a key problem in the fields of computer vision and remote sensing. At present, supervised learning methods have achieved impressive results, but, due to domain bias, the trained model cannot be directly applied to a new scene. In this paper, we propose a novel semi-supervised framework, StyHighNet, for accurately estimating the height of a single aerial image in a new city that requires only a small number of labeled data. The core is to transfer multi-source images to a unified style, making the unlabeled data provide the appearance distribution as additional supervision signals. The framework mainly contains three sub-networks: (1) the style transferring sub-network maps multi-source images into unified style distribution maps (USDMs); (2) the height regression sub-network, with the function of predicting the height maps from USDMs; and (3) the style discrimination sub-network, used to distinguish the sources of USDMs. Among them, the style transferring sub-network shoulders dual responsibilities: On the one hand, it needs to compute USDMs with obvious characteristics, so that the height regression sub-network can accurately estimate the height maps. On the other hand, it is necessary that the USDMs have consistent distribution to confuse the style discrimination sub-network, so as to achieve the goal of domain adaptation. Unlike previous methods, our style distribution function is learned unsupervised, thus it is of greater flexibility and better accuracy. Furthermore, when the style discrimination sub-network is shielded, this framework can also be used for supervised learning. We performed qualitatively and quantitative evaluations on two sets of public data, Vaihingen and Potsdam. Experiments show that the framework achieved superior performance in both supervised and semi-supervised learning modes.

Modifying the existing two-way street into a one-way street can alleviate the traffic congestion in a megacity and has the characteristics of economy saving, convenience, and quickness. However, at present, the setting of one-way street in China is mostly determined by human experience and lack of scientific basis. In this context, a one-way street network planning model is established in this paper. According to this model, the optimal method of adding a one-way street on the existing traffic network is found, solved by genetic algorithm. The abstract things are quantified, and some feasible, specific, efficient implementation steps to design a one-way street network are provided for the traffic control department. In addition, taking the traffic in the core area of Tongzhou New City as an example, this paper uses the one-way street planning model to construct the actual street network model and the one-way street network model in the core area of the Tongzhou New City and compares their simulation results. The results show that using the one-way street planning model to modify part of the two-way street into a one-way street in the core area of the Tongzhou New City can indeed improve the traffic operation of the area.

Two aspects of Schumpeter' legacy are analyzed in the article. On the one hand, he can be viewed as the custodian of the neoclassical harvest supplementing to its stock of inherited knowledge. On the other hand, the innovative character of his works is emphasized that allows to consider him a proponent of hetherodoxy. It is stressed that Schumpeter's revolutionary challenge can lead to radical changes in modern economics.

Sexual Repression

This article examines how female conditioning and sexual repression affect the woman’s sense of self, womanhood, identity and her place in society. It argues that the woman’s body is at the core of the many sites of gender struggles/ politics. Accordingly, the woman’s body must be decolonised for her to attain true emancipation. On the one hand, this study identifies the grave consequences of sexual repression, how it robs women of their freedom to choose whom to love or marry, the freedom to seek legal redress against sexual abuse and terror, and how it hinders their quest for self-determination. On the other hand, it underscores the need to give women sexual freedom that must be respected and enforced by law for the overall good of society.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

Deep-learning technologies, especially convolutional neural networks (CNNs), have achieved great success in building extraction from areal images. However, shape details are often lost during the down-sampling process, which results in discontinuous segmentation or inaccurate segmentation boundary. In order to compensate for the loss of shape information, two shape-related auxiliary tasks (i.e., boundary prediction and distance estimation) were jointly learned with building segmentation task in our proposed network. Meanwhile, two consistency constraint losses were designed based on the multi-task network to exploit the duality between the mask prediction and two shape-related information predictions. Specifically, an atrous spatial pyramid pooling (ASPP) module was appended to the top of the encoder of a U-shaped network to obtain multi-scale features. Based on the multi-scale features, one regression loss and two classification losses were used for predicting the distance-transform map, segmentation, and boundary. Two inter-task consistency-loss functions were constructed to ensure the consistency between distance maps and masks, and the consistency between masks and boundary maps. Experimental results on three public aerial image data sets showed that our method achieved superior performance over the recent state-of-the-art models.

Abstract The article examines how the aspects of the social world are enacted in a theater play. The data come from a videotaped performance of a professional theater, portraying a story about a workplace organization going through a personnel training program. The aim of the study is to show how the core theme of the play – the teaming up of the personnel – is constructed in the live performance through a range of interactional means. By focusing on four core episodes of the play, the study on the one hand points out to the multiple changes taking place both within and between the different episodes of the play. On the other hand, the episodes of collective action involving the semiotic resources of singing and dancing are shown to represent the ideals of teamwork in distinct ways. The study contributes to the understanding of socially and politically oriented theater as a distinct, pre-rehearsed social setting and the means and practices that it deploys when enacting the aspects of the contemporary societal issues.

Confucianism has made a comeback in mainland China over the last two decades or so. Politically minded Confucian revivalists see Confucianism as the core of national identity that differs from ‘‘foreign’’ traditions such as liberalism and they argue for replacing Marxism with Confucianism as the core ideology of the one-party state. But is the ancient tradition of Confucianism compatible with the modern tradition of nationalism? And is it possible to defend a morally appealing form of ‘‘Confucian nationalism’’? This essay argues that both questions can be answered affirmatively.

Several phenotypes can come from transcription regulation. Sequence-specific transcription factors are needed to effectively execute transcriptional programs, however they are often not operating alone. Polycomb PcG proteins are a well-known class of chromatin regulators found in Drosophila melanogaster and other species, including humans. As time passed, the concept of a PCG gene or protein shifted from the original phenotypic meaning of mutant flies to the contemporary biochemical description. PCG genes and proteins are under investigation for their critical contributions to physiology and their cancer treatment potential. Adding additional PcG members, with substantial responsibilities in PRC modulation, has opened new routes of inquiry in the issue. It is still needed to discover the many PRC variations' roles and how their catalytic activity is controlled. This review covers mutually exclusive PRC2 variants and employs a technique like the one used for PRC1 variants. Based on current biochemical findings, these classifications are valid. More auxiliary PcG subunit research is needed for now. Moreover, it is unknown how many PRC cell variations occur (hypothetically, there could be more than 100 different PRC variants).In order to fully elucidate the new PcG proteins and complexes, it is necessary to perform comprehensive research. We must study context-specific genetic modifications to better provide remedies. Current anti-cancer drugs target mainly the core subunits and catalytic activity of PRC2 and PRC1, and understanding these functions is critical. Targeting each particular activity that has been deregulated might be rather beneficial. PCG proteins are involved in oncogenesis, tumor suppression, and development/congenital illness as well. PcG involvement in cancer, once revealed, would be intriguing. Successful and effective therapeutic therapies will be helped by a detailed understanding of the pathways that contain PcG proteins.
