人类基因组计划的研究取得了令人瞩目的成就,其成果主要表现在“四张图”上：遗传图谱、物理图谱、转录图谱和序列图谱。结构基因组学时代正向功能基因组学时代过渡,新时代的最终目的,是阐明基因组所表达的真正执行生命活动的全部蛋白质的表达规律和生物功能。中国面临着严峻的挑战,必须采取相应对策,吸收和借鉴国外在人类基因组计划研究中采用的最新技术和方法,并不断创新。     

The building recognition and analysis of remote sensing image based on depth belief network

The deep belief network model, which is widely used in deep learning, consists of a multi-layer constrained Boltzmann machine and a back-propagation network. The authors have conducted parameter sensitivity experiments on the number of iterations, the number of hidden layers and the number of hidden layer nodes in the DBN network for remote sensing image classification, and obtained a set of optimal parameter setting schemes. Moreover, the DBN algorithm has been enhanced with an improved Dropout strategy. The improved Dropout strategy selects only part of the data to clear the weight at a time, and a local area randomly clear strategy is adopted, which will save the local information of the image itself, and enhance the generalization ability of the model. In order to verify the advantages of the improved DBN algorithm model, the classification results of DBN, KNN, random forest and SVM have been compared. And the results show that classification accuracy of the improved DBN has been greatly improved, which is increased by about 2.5% compared to DBN. The improved DBN classification results are processed then, including connected areas marking, noise removal, morphological transformation and edge extraction, and the boundary information of the building is obtained according to the target shape characteristics. Finally, the experiment on the morphological characteristics of the building also shows it can extract better edge information of the building.

Conference spaces as emotional sites for becoming campus sustainability leaders

This paper applies a feminist political ecology approach to ask: How do sustainability in higher education (SHE) conference events co-produce the subjectivities and expertise of campus sustainability professionals (CSPs) emotionally? Specifically, how do SHE conference spaces cultivate particular embodied practices and discourses in CSPs who are meant to translate at times irreconcilable practices and discourses in their daily campus-based work? Through multi-event ethnography and autoethnography of SHE events and comparisons with academic conferences more broadly in my role as a teacher-scholar-activist, I analyze how CSPs encounter and challenge ‘green’ knowledge claims emotionally. Vignettes from a sample of conference spaces demonstrate that SHE events provoke a confusion of conflicting emotions, all while promoting products, services and solutions to ‘fix’ the distressing emotions they provoke. Furthermore, the emergence of informal and formal wellness discourses and performances at SHE conferences re-directs CSPs away from critical questions of power toward self-centered, technocratic and technophilic solutions. A politics of failure can challenge audit culture, the bullshitization of sustainability work and neoliberal tropes of professionalism and self-improvement. Such a politics compliments ongoing efforts to center justice-oriented work in sustainability.     

How Emotional Are Populists Really? Factors Explaining Emotional Appeals in the Communication of Political Parties

Are populists really more emotional than mainstream parties? The alleged link between populism and emotional communication has barely been subject to systematic empirical scrutiny. I use literature on populist communication and appraisal theory to generate expectations about which political parties use which emotional appeals. I test these claims by applying a novel emotional dictionary to a large set of text data including more than 700,000 press releases and tweets from three European countries. As expected, I find that populist parties use significantly more negative emotional appeals (anger, fear, disgust, sadness) and less positive emotional appeals (joy, enthusiasm, pride, hope) than mainstream parties. Furthermore, I find that political actors adapt the usage of emotional appeals to different purposes depending on the communication medium and the politicians' status level. This study entails important implications for the research on emotional appeals in politics and populist communication.     

基于干扰物特征的统计规则对注意抑制效应的影响

采用经典的额外单例范式的变式, 通过操纵基于干扰物颜色的统计规则, 考察其对注意抑制效应的影响。结果发现：(1)当迫使被试采取特征探测策略时, 与无颜色独子的条件相比, 被试在所有呈现独子的条件中反应都显著较快; (2)与呈现低概率颜色独子条件相比, 呈现高概率颜色独子条件下被试的反应显著较快。研究表明, 统计规则对注意的影响不局限于刺激位置, 基于干扰物特征的统计规则也会影响注意抑制效应的大小。     

Of deadly beans and risky stocks: Political ideology and attitude formation via exploration depend on the nature of the attitude stimuli

An attitude formation task examined how conservatives and liberals explore information about novel stimuli and form attitudes towards them. When framed as the BeanFest game, conservatives sampled fewer beans and exhibited a stronger learning asymmetry (i.e., better learning for negative than positive beans) than liberals. This has been taken as strong evidence that conservatives are more sensitive to negative stimuli than liberals. We argue that the learning asymmetry and sampling bias by conservatives is due to framing of the game. In addition to the BeanFest, we framed the game as StockFest (i.e., a stock market game) where participants learned about novel stocks. We replicated the pronounced learning asymmetry for conservatives in the BeanFest game, but found a pronounced learning asymmetry for liberals in the StockFest game. We suggest that conservatives and liberals are equally sensitive to negative stimuli but in different domains.     

Is this a good time? Political activism and other in the temenos

This paper discusses raciality and Africanist culture as elements of the analytical clinical experience. The history of American Jungian psychology, and its relationship with the African diaspora, is reviewed with a perspective that seeks to deepen understanding of racism as an aspect of psychoanalytical institutional life. An attempt to separate political activism from the clinical setting is explored with consideration of the necessary intertwining relationship between socialization, racial identity and racism. Diversity and inclusion are becoming cultural signature markers of clinical work with individuals who have oftentimes, within the psychoanalytical clinical setting, been described due to ethnicity, as other. Political activism such as the Black Lives Matter movement stretches consciousness towards an insistence that blackness matters, skin colour matters and the lives of Africanist individuals matter. This paper reflects on cultural racial identity, the influence of politics on the individual, and the effects of these on the analytical relationship.
