Accurately predicting the movement of stock prices can help people make more informed investment decisions and thus obtain higher returns. They can also assess market trends, develop investment strategies and provide investment advice. In this paper, we used 5 models including Random Forest, XGBoost, ANN, RNN, LSTM to predict and verify the fit of 3 companies (AMZN, BABA and MSFT). It is found that LSTM and random forest model can predict well in most cases. The development of the financial industry does have some shortcomings, and the future financial field will be a field full of challenges and opportunities, so some machine learning and deep learning methods can be used to solve the prediction and modeling problems of financial aspects such as the stock market.

Cet article propose d'aborder la question du positionnement entre qualitatif et quantitatif (que suppose l'analyse informatisée de données textuelles) au travers d'exemples concrets tirés d'un projet de recherche se situant dans le domaine de la création littéraire et son rapport aux savoirs biologiques (Biolographes :http://biolog.hypotheses.org). Une première partie expose les aspects pratiques des corpus numériques, de l'accès aux sources à leurs métadonnées, en passant par les questions d'océrisation et de stockage (base de données). Les deuxième et troisième parties illustrent la façon dont des outils textométriques et de visualisation (TXM, Treecloud) servent de point d'appui, dans le cas de grands corpus, à de nombreuses hypothèses de travail. En conclusion, il souligne le pont opéré par le TAL entre les outils informatisés et l'analyse littéraire.

State repression includes harassment, surveillance/spying, bans, arrests, torture, and mass killing by government agents and/or affiliates within their territorial jurisdiction. Over the past 40 years, the systematic study of state repression has grown considerably. The development of this work, however, has been uneven. Though unified in their focus on the problem of order (i.e., trying to ascertain how political authorities wield coercive power amid potential and actual domestic challengers), different scholars tend to emphasize distinct aspects of the topic. Consequently, a great deal of progress has been made in specific areas but others have lagged behind. In this review, I attempt to identify the dominant traditions in the repression literature, the core empirical findings, and some persisting puzzles. Adapted from the source document.

When people talk about the growing ubiquity of the computer presence they tend to fall back on two images: the computer as tool and the computer as toy; objective instrumentality and engrossing play. This paper examines another dimension to the impact of the computer on individuals: a subjective dimension. What people do with computers weaves itself into the way they see the world. People use a discourse about computers for thinking and talking about other things, about politics, religion, education, and about themselves and other people. The subjective dimension of the computer presence is not merely a matter of discourse, of using the computer intellectually as a metaphor or model. There is another, and more emotionally charged aspect which does not engage ideas about computers as much as the immediate quality of an individual's experience when working with them. Working with computers can be a way of 'working through' powerful feelings. This essay develops this idea by using as a case study a group of computer users for whom issues related to control are particularly salient. For a first generation of computer hobbyists, controlling the computer which they experience as a safe and completely knowable microworld is a way to deal with frustrations and aspirations, both personal and political, that have nothing to do with the computer per se.

В статье рассматривается государственная культурная политика на современном этапе в социально-культурном аспекте. Государственная культурная политика это сложная система, включающая политический компонент, где принимаются законодательные акты, решения на самом высоком уровне, и исполнительские функции, которые выполняют все государственные структуры, начиная от Правительства РФ, министерств федерального, регионального масштаба до органов самоуправления на местах. Социально-культурная политика государства определяет и регулирует деятельность центральных правительственных и муниципальных учреждений, комитетов, комиссий, а также общественных и коммерческих организаций, в своей работе ориентированных на цели, которые перед ними ставятся прямо или косвенно и которые затрагивают интересы всех слоёв населения. Государственная политика в социально-культурной деятельности сегодня направлена на преодоление узковедомственных подходов федеральных органов власти при решении актуальных проблем и на преодоление разобщённости в их деятельности. ; The article examines the state cultural policy at the present stage in the social and cultural aspect. State cultural policy is a complex system, which includes a political component, which is subject to legislative acts, decisions at the highest level and executive functions that perform all state structures, from the Russian Government, the federal ministries, regional governments scale up the field. Social and cultural policy of the state defines and regulates the activities of the central government and local government agencies, committees, commissions, as well as public and commercial organizations, their work focused on goals that are put in front of them, directly or indirectly affect the interests of all segments of the population. State policy in the social and cultural activity today is aimed at overcoming the bureaucratic approach of the federal government in solving urgent problems and to overcome fragmentation in their activities.

This Handbook presents established and innovative perspectives on involving older adults as co-creators in ageing research. It reorients research and policy toward more inclusive and adequate designs that capture the voices and needs of older adults. The Handbook: introduces types of participatory approaches in ageing research; highlights key methodological aspects of these approaches; gives insights from projects across different cultural contexts and academic disciplines, showing ways in which older participants can be involved in co-designing different stages of the research cycle; examines key issues to consider when involving older participants at each step of the research process; includes the voices of older adults directly; draws out conclusions and points ways forward for future research. This Handbook will be essential reading for researchers and students interested in the field of ageing and/ or participatory methods, as well as for those policy stakeholders in the fields of ageing and demographic change, social and public policy, or health and wellbeing who are interested in involving older adults in policy processes. It will be useful for third-sector advocacy organizations and international non-governmental and public agencies working either in citizen involvement/participation or the ageing sector.

"In The Dignity Doctrine: Rational Relations for an Irrational World, Mark C. Coleman explores how business and consumers address the effects of human-induced ecological degradation, climate change, and the negative aspects of advanced technologies on our freedoms, dignity, and security. Real-life examples of ways to attain a more peaceful, just, and sustainable world as we navigate our precarious relationships with others-including our Earth and it's precious resources-are drawn from Coleman's challenging personal experiences and career as a consultant for practitioners of sustainability in business. The Dignity Doctrine offers alternatives to the irrational, uncivil political discourse and social unrest happening thoughout the world. In his call to action for more rational relations, Coleman advances themes of accountability, trust, and integrity and a deeper understanding of our life's purpose as caretakers of all living beings on our planet. He advises that self-respect and respect for others inspires the ingenuity to create a more sustainable world. Coleman offers both an inspiring perspective and a logical framework for anyone seeking to create positive change in their life and those whose goal is to achieve sustainable enterprise through more constructive discourse and meaningful relationships"--

Weaving together insights from social psychology, theology, and experiences of interfaith religious leaders, Dagmar Grefe develops practical strategies that support interreligious contact at a grassroots level. She shows that by working together, religious communities can more effectively address global and local problems that all people face: poverty, environmental destruction, and armed conflict. Grefe describes interreligious cooperation at work in local communities. She develops tools that equip religious leaders with the interreligious competence needed for spiritual care and counseling with individual persons in crisis. Cooperation is not only effective in the care for communities and persons in crisis, it also heals distant and strained interreligious relationships. In the process of working together, perceptions of each other can transform

This comprehensive and authoritative book offers a global approach to the modern economics of the family, family law and family policy. Beginning with the division of labour in the family, this book deals with the economics of marriage, the demand for children, inter-generational relationships, and the economics of inheritance. The family is analysed using the theory of utility maximisation assuming that individuals wish to achieve the greatest possible satisfaction with limited resources and imperfect knowledge. The family is examined from both long and short term perspectives, and it is assumed that the family is cooperative with incentives for altruistic behaviour greater than in any other social group

With the election of Barack Obama as the first black president of the United States, the issue of racial justice in America occupies center stage. Have black Americans finally achieved racial justice? Is government intervention no longer required? Racial Justice in the Age of Obama considers contemporary civil rights questions and theories, and offers fresh insights and effective remedies for race issues in America today. While there are now unprecedented opportunities for talented African Americans, Roy Brooks shows that lingering deficiencies remain within the black community. Exploring solutions to these social ills, Brooks identifies competing civil rights theories and perspectives, organizing them into four distinct categories--traditionalism, reformism, limited separation, and critical race theory. After examining each approach, Brooks constructs the best civil rights theory for the Obama phase of the post-civil rights era. Brooks supports his theoretical model with strong statistics that break down the major racial groups along such demographics as income and education. He factors in the cultural and structural explanations for the nation's racial divisions, and he addresses affirmative action, the failures of integration, the negative aspects of black urban culture, and the black community's limited access to resources. The book focuses on African Americans, but its lessons are relevant for other groups, including Latinos, Asians, women, and gays and lesbians. Racial Justice in the Age of Obama maps out today's civil rights questions so that all groups can achieve equality at a time of unprecedented historical change.

This dissertation in microeconomic theory is composed of four chapters. The first two chapters investigate two closely related normative questions. How can we compare different distributions of a multi-goods endowment among individuals that care for their relative situation? How can we compare the poverty in different income distributions when both the absolute and relative aspects of income matter? The outputs of these chapters are indicators able to rank economic outcomes as a function of their adequacy with the principles of Pareto efficiency and equality of resources. The third chapter aims at comparing different mechanisms used for the allocation of economic resources among individuals holding private information, e.g. their preferences over these resources. This implies studying both the incentives these mechanisms provide and the properties of the allocations to which they lead. The chapter proposes a general criterion for comparing the performance of allocation mechanisms and apply this criterion to the stability of school choice mechanisms. The last chapter focuses on the strategic interactions between individuals averse to ambiguity. It proposes a new interpretation for equilibria in ambiguous randomization strategies. ; (POLS - Sciences politiques et sociales) -- UCL, 2015

Although the study of LGBT (lesbian, gay, bisexual, transgender) politics appears to be widely accepted within political science, a recent survey of political scientists reported some skepticism about its legitimacy and scholarly worth (Novkov and Barclay 2010). This article examines potential concerns about LGBT studies and draws attention to the field's scholarly importance. The first part briefly addresses three objections to the study of LGBT politics that echo criticisms of the study and practice of identity politics. I argue that these objections do not withstand scrutiny, and that the case for studying the intersection of politics and sexuality within the discipline of political science is compelling. Sexuality and gender are fundamental aspects of human societies that reflect power relations and increasingly have become the object of public policy. The second part of the article examines the burgeoning literature on the politics of sexual orientation and identity. Beyond its intrinsic importance, LGBT politics contributes to a broader understanding of politics, power, social movements, public opinion, policymaking institutions, urban politics, and the relationship between science and public policy. Though not exhaustive, this review addresses many of the principal empirical and theoretical works in this area.
