② 现在的婚恋交友网站靠谱吗会有骗子吗

有人说过，中国人厉害的地方，就是把什么都做成生意。其实这话不对，是任何事本身就是生意，只是你去不去做的问题。当我们看到一个社会的改变其实是从一桩生意开始的时候，恐怕更能理解为什么我们这个社会有了如此深刻的变化。那么成都婚介机构开办了网络婚恋交友网站靠谱吗？

在一个婚介机构开张的13年后，网络开始有了交友的网站，更多的社会关系被重新进行了整合。从那时候开始，一次更深刻的社会关系的鼎革又走了13年，相信任何人都会说，这些年我们的社会更加宽容、更加能接受新的生活方式了。这方面的进步，都是从一个婚介机构开始的。

“那个时候，人们热衷参加集体活动，又是组织给安排的，安全有保障”，成都资深婚恋专家王老师说，对于大龄青年来讲，参加类似集体活动是非常时髦的事情。

但退休之后还想有自己的工作，专心来解决“找对象”问题。王老师说，于是，2004年，成都的一家退休机关干部举办的婚介成立，由退休机关干部坐镇，隶属成都市专门为单身的婚姻服务，并配备工作人员。

还有一位领导干部的儿子来所里准备登记时，要求给他找一个处级干部的女儿。婚介里没让他登记，而是对他进行思想教育，批评他“门当户对”是世俗观念，说得这位干部子弟后来都不好意思公开他父亲的名字。

其实现在看来经过这些年的发展婚介的市场越来越多，以城市居多。婚介所的生意也很红火。现在仅成都市，年龄在35岁到50岁的单身男女就有50多万人。单身男女持有效证件注册为婚介所会员后，婚介所会根据他们的择偶要求，从会员中介绍条件合适的人选与其认识。据业内人士透露，一些大的婚介所，有几万名到十几万名会员。但是都是通过实名认证，有些连婚恋网站都要求实名制管理。成都尊诚情缘负责人说。

④ QTUM-量子链是什么

.
投资比特币现在的收益也没有那么高啊。我所知道的这类理财产品都属于高利贷，年化率高于24%的一般都不被国家保护。我所知道的，月盈利30%的都是一些传销骗局，例如BBT造币机就是这样。
当然，也许你会反驳我，因为你确实获得了收益，但如果不让你尝到甜头，你会投资更多的资金吗，会去拉人头吗？这个可以去网络一下旁氏骗局。

A. 马斯洛需求层次理论

Maslow's Hierarchy of Needs

从对食物的需求过渡到互联网信息科技时代

对健康、安全、娱乐、爱和价值

对知识产权保护等更高级的需要

1.Biological and physiological needs- air, food, drink, shelter, warmth, sex, sleep.

2.Safety needs- protection from elements, security, order, law, stability, freedom from fear.

3.Love and belongingness needs- friendship, intimacy, trust, and acceptance, receiving and giving affection and love. Affiliating, being part of a group (family, friends, work).

4.Esteem needs- (i) esteem for oneself (dignity, achievement, mastery, independence) and (ii) the desire for reputation or respect from others (e.g., status, prestige). The need for respect or reputation is most important for children and adolescents and precedes real self-esteem or dignity.

5.Cognitive needs- knowledge and understanding, curiosity, exploration, need for meaning and predictability.

6.Aesthetic needs- appreciation and search for beauty, balance, form, etc.

7.Self-actualization needs- realizing personal potential, self-fulfillment, seeking personal growth and peak experiences. A desire “to become everything one is capable of becoming”.

8.Transcendence needs- A person is motivated by values which transcend beyond the personal self (e.g., mystical experiences and certain experiences with nature, aesthetic experiences, sexual experiences, service to others, the pursuit of science, religious faith, etc.).

B. 全球化与殖民主义：主流文化入侵

Post-colonialism & Cultural Imperialism

Impact on Global Communication

从互联网到全球联系的增强

从科技和文化霸权看帝国殖民

从创新发展到本土文化的逐渐模糊与丧失

宗教、语言、民俗的趋同

Cultural Imperialism: the extension of influence or dominance of one nation’s culture over others, through the exportation of cultural commodities.

Global communication: the communication practice occurring across national borders, social, political, and cultural divides. The need for global communication has increased e to the expanse of globalisation.

The World Systems Theory: an inter-regional and transnational division of labour with core, periphery, and semi-periphery countries.

In its conquest of Italy, the Roman Empire imposed Latin on the people of Etruria, replacing the Etruscan language, which ultimately led tothe demise of the language and other aspects of the Etruscan culture. Then, Latin was the lingua franca and today English isthe lingua franca of global communication

The expansion of the British Empire ring the eighteenth and nineteenth centuries: cultural form of imperialism, throughreligious proselytising, i.e. the imposition of Christianity on cultures with other religions.The British Empire also exerted its cultural power throughimposing ecational material on the colonies, promoting the empire through books and syllabuses, serving the interest of colonialism.

The assimilation of media:literature, film, television, Internet, and music.

US media and entertainment instries, like Hollywood and Disney, are able topenetrate the global market and export US-American cultural procts and values.

C. 资本主义、信息共享与互联网

Capitalism and the Internet

资本主义剥削形式、人们工作方式的转变

new way to exploit the working class

without having to work in factories

时长加长，无形的工作与生产

more time investment, longer exploitation

enhance possibilities to enjoy their work

give rise to a new proletarian identity

eventual confrontation with capital owner

Internet is just the development of past ways of entertainment, communication and knowledge (games, libraries, letters, books, etc.) which helped spread ecation and information throughout society andlower classes as they became more and more reachable and affordable, whilst also,especially in the case of entertainment, alienating people from their nature (workers- not in a bad connotation).

New technology hastranscended the standard capitalist business model.

Intangible, conceptual assets: a large part of corporate wealth, likeintellectual property, trademarks, patents and right. Microsoft is not valued principally in physical capital assets, as was the case with big corporations in the past. What Microsoft claims to own isideas, ideas that we all need to run factories and offices and to communicate with each other.

As Thomas Jefferson put it,passing light on to another candle does not diminish the light from your own. Jefferson thought this was a good enough reason whyideas should not be treated like coal, candles and other commodities, but should be allowed to circulate freely for the common good.

D. 科技创新和女权主义

Technology and Gender Gap

技术教育不足，科技行业需要却鲜有女性

男性主导、敌意的工作环境，高离职率低薪

Women have been left out of the mainstream of recorded technological development. Technology, increasingly so in instrialized societies, is male.

A feminist perspective can help us move from a hard technology society to a soft technology future in which values such asharmony with nature, subjectivity, co-operation, and non-exploitationbecome integral to technological development.

In the 1980s, women made up a little under40 percent of computer-science graates.Since then, the gender gap has grown: Currently, less than 20 percent of computer-science graates are women. In the earliest days of programming, ring World War II, building computers was deemed a macho thing, and programming was thought to be for typists. Later, when personal computers began to appear in homes and offices, they were promoted as apastime -- for boys.Contemporary bro culture has done nothing to attack this bias.

School should expand thefemale facultyand make thecurriculummore inviting to talented students withlimited exposure to computer science: assign classes according to students' past programming experience -- to prevent long-time enthusiasts fromintimidating novices.

bloomberg.com/view/articles/2017-09-06/how-to-close-the-gender-gap-in-tech

The tech instry's gender imbalance is no secret – only 17% of technology specific jobs are held by women.Projects to counter the problem, from conferences to mentorship programmes, are becoming widespread but are usually aimed at women already embarking on careers.

From toys to language, teaching girls basic skills and busting gender myths from an early age could encourage more women into tech careers.
