淺談「假新聞」

最近上課時學到一個新單字「positionality」，讓我想到當前社群媒體上，不停看到的「fake news」——假新聞。

簡言之，「positionality」(位置性) 被定義為於種族、階級、性別、性取向以及能力等狀態中，創造你身分的社會與政治背景。位置性還描述了你的身分如何影響你對世界的理解與看法，以及潛在的偏見。

positionality 位置性；定位

以下是我對「positionality」與 「fake news」的些許觀點：

“Fake news” has permeated all facets of life, ranging from social media interaction to presidential elections. Fake news can be defined as “fabricated information that mimics news media content in form but not in organizational process or intent” (Lazer et al., 2018, p. 1094). The creators and outlets of fake news do not ensure the accuracy and credibility of information, but rather disseminate misinformation or disinformation for purposes ranging from personal amusement to creating deceptions to achieve political aims. At times, fake news is created and disseminated by state or non-state actors using social media accounts and networks of bots designed to hijack feed algorithms of platforms such as Twitter or Facebook (Prier, 2017, p. 54). In the 2016 U.S. presidential campaign, Facebook estimated that up to 60 million bots were used to post political content. Some of the same bots were then used in an attempt to influence the 2017 French election (Lazer et al., 2018, p. 1095). Such campaigns can be understood as a form of information warfare, a comprehensive attempt to control and influence every facet of the information supply chain, thereby influencing public opinion and behaviors. (Prier, 2017, p. 54). Often, fake news is not directly created by actors that seek to manipulate but by journalists or content creators whose content favors or aligns with the narratives of these actors (Doshi, 2020).

從社群媒體的互動到總統選舉，「假新聞」（fake news）已滲透至生活的各個層面。假新聞可被定義為「在形式上而非組織過程或意圖上，模仿新聞媒體內容所捏造的資訊」（Lazer et al., 2018, p. 1094）。無論是出於個人愛好或為達政治目的而有所欺瞞，假新聞的製造者與傳播管道並不保證資訊的準確性與可信度，反而是為了散播錯誤訊息（misinformation）或扭曲訊息（disinformation）。有時，假新聞是由國家或非國家行為者（state or non-state actors）所製造與傳播，藉由社群媒體帳號及網絡機器人來劫持諸如臉書與推特等平臺的推送演算法（Prier, 2017, p. 54）。在2016年的美國總統大選中，臉書估計有多達６千萬個機器人被用來發布政治貼文。其中，有部分機器人被用於影響隔年的法國大選（Lazer et al., 2018, p. 1095）。此類行動可視為資訊戰（information warfare）的一種形式，一種對控制與影響資訊供應鏈各環節的全面嘗試，從而影響公眾輿論與行為（Prier, 2017, p. 54）。假新聞通常是由記者或內容創造者（content creators）所創造，而非試圖操弄的行為者，前者的內容偏好符合後者的敘事（Doshi, 2020）。

Nevertheless, while the term “fake news” is commonplace, there is no universal, measurable way to quantify the fakeness or truthfulness of news. There are many fact-checking and media-bias detection tools, but they cannot objectively detect and clarify the more subtle and nuanced aims of manipulative actors that play a crucial role in news production. It can also be argued that the veracity of news depends not only on the actors that seek to manipulate it, but also on the positionality of its consumers. Therefore, one’s initial line of defense against misleading news lies not in the plethora of fact-checking devices but more in one’s pre-existing dispositions and skills to think and act in response to misleading information. This ability can be referred to as critical thinking, which can be more concretely expounded as “reasonable and reflective thinking focused on deciding what to believe or do” (Ennis, 2011, p. 15).

然而，即便「假新聞」一詞隨處可見，卻沒有統一、可衡量的方式來量化新聞的虛假性或真實性。目前有許多事實查核與媒體偏見檢測工具，但它們無法客觀地檢測與說明行為操弄者更狡猾、更細緻的目標，而這些操弄者往往在新聞的生產中發揮著重要作用。我們也可以說，新聞的真實性不僅取決於試圖操弄它的行為者，同時還取決於新聞受眾的位置性。因此，一個人對抗誤導性新聞的第一道防線，不在於這些五花八門的事實查核方式，反而在於個人所固有的性格，以及針對誤導性資訊的思考與行動等相關技能。這種能力可稱為批判性思考（critical thinking），意即「專注於決定相信什麼或做什麼的理性思考與反思性思考」（Ennis, 2011, p. 15）。

Taiwan, also known as the Republic of China (ROC), is at the forefront of information warfare. It is wedged between the geopolitical struggles of global and regional hegemonies such as the United States and China, the People's Republic of China (PRC). Compounding the matter are the Taiwan’s own political actors vying for influence and power. This struggle seeps into all aspects of life and practice, mainly manifesting itself on social media, a battleground of information warfare. The Ministry of Education of Taiwan is cognizant of these information campaigns, and efforts have been made to introduce media literacy into all parts of its education system. According to the ministry, the government has tried to promote media literacy education since 2000 (MOE, 2002, p. 1), with one of its primary goals to cultivate its “citizens” abilities for independent learning, critical thinking, and problem solving” (MOE, 2002, p. 2).

臺灣，也被稱為中華民國，正處於資訊戰的最前線。這是全球霸權與地區霸權之間——如美國與中國（中華人民共和國）——的地緣政治對抗。使問題惡化的是臺灣自身的政治行動者對影響力與權力的奪取。這場對抗遍布於現實生活的各個面向，主要於社群媒體中——資訊戰的戰場——展露無遺。臺灣的教育部注意到了這些資訊的煙硝，並已努力將媒體素養引入其教育體系。據該部稱，自2000年以來，政府一直試圖推展媒體素養教育（MOE, 2002, p. 1），其主要目標之一是培養「公民獨立學習、批判性思考以及解決問題的能力。」（MOE, 2002, p. 2）。

★★★★★★★★★★★★

上述段落認為，由於個人的位置性(positionality)，「假新聞」極難定義。此外，有許多人把不符合自身成見與偏好的新聞逕斥為假新聞。這其實相當危險，因為個人觀點將會變得愈發孤立與激進。

閱聽人應意識到，他們在網路上看到的每個資訊都有特定立場。是否真有毫無立場的新聞文章？為了對抗操弄性或強制性資訊（coercive information），我們必須意識到權力於個中的作用，以及我們自身的位置性如何形塑我們的詮釋。這是我們的第一道防線。

整理資料發現近兩年前去某國際研討會分享 #手天使 心得時的講稿，當時把我知道的議題面向都寫進去了。貼上來給有興趣的朋友。

[[slide page 1]]
Thank you for attending this part.
I'm from Hand Angel, a non-profit organization of Taiwan.

The title of my presentation is "As a sex worker and a sex volunteer",
since I'm both a sex worker, and also attending Hand Angel as a sex volunteer.

[[slide page 2]]
Allow me to introduce my organization more,
though you may know some from what Vincent has said in the morning.

Our main tenet is sexual rights to people with disabilities.

[[slide page 3]]
This includes not only orgasm, but also the right to control one's sexuality with autonomy and without discrimination.
People know us usually because we provide limited sexual service for servere physical or visual disabilities, including females.

Hand Angel is not a registered organization in Taiwan,
since we literally provide sexual service, which is considered against public order and morals.

However, we are still able to initiative our idea on the table
because our service are free, which means we actually do not violate any law.

[[slide page 4]]
In Taiwan, the definition of "sexual transaction" includes obscene acts in exchange for monetary,
which means it's considered transactional sex even there is no sexual intercourse.
And since transactional sex is technically illegal in Taiwan,
there's no legal way for us to charge anything by providing any service which may be considered obscenity.

This is much different in other countries.
In Japan, the law prohibiting sexual transaction only applies to intercourse between one male and one female. That's why White Hands and NOIR are able to provide paid handjob. The other reason is that they seem do not locate their service as sexual transaction. We can talk about this difference later.
And in Hong Kong, there's some way for sex workers not to be punished, which is called "one-woman brothel". So the difficulty for people with disabilities to satisfy their sexual desire would be different.

I, who has been a sex worker for years -- under the table, of course -- was invited to join Hand Angel at its very beginning.
[[slide page 5]]
People keep asking me that how a sex worker would think about a free sexual service.
But before that question, I think it's more important for us to know the difference other than money.
What's the difference between a classical transactional sex and our service?

As a sex worker, I hope my customers will come back to me more and more, as many times as they can pay.
But as a member of Hand Angel, I hope the servees would not need us anymore.
In fact, I hope they don't have to come to us at the very beginning.

The reason why people with disabilities may need sexual service, is the absence of sexual resource, the resource to fulfill one's sexual desire.

This is just like other issues of disabilities.
[[slide page 6]]
Just providing a service would not resolve the structural problem.

For example, if you give food to the poor without changing their situation, you would end up finding out that they're still poor.
Now change the "food" to "sex".
If we just give our own sex to those who barely have sexual resource, we'll end up exploiting ourselves, and their bad situation still remains.

The problem is, disabled people are considered abnormal, and they have been treated as no unnecessary needs.
But what is necessary for a person to live her own life instead of just survive?
In our issue, disabled people are usually considered asexual, and seldom sexy. That's the stigma we're going to break down.

[[slide page 7]]
There are some textures talking about disabled people in love and having sex, such as "Scarlet Road", "Sex on Wheels", and "The Sessions".
However, the narrative are usually based on ableism.
Viewers usually focus on how can the service provider "bear" to have sex with disabled people, instead of seeing the obstacles disabled people encounter.

[[slide page 8]]
A feminist has said that the relationship a disabled person has is considered depending on the compassion of the other person. People think their sexuality is disgusting and only saints are able to tolerate it.

So we can see the problem is not only physical obstacles, but also how we think about intimate relationship a disabled person deserves.

[[slide page 9]]
Does Hand Angel care about intimate issue? The answer is yes.
In our service, we provide not only sexual service. Our target is not the physical orgasm, but the infinite opportunity of their own lives.
Here are two examples.

[[slide page 10]] Little Prince
Since this servee can sense nothing below his waist, a classical handjob would be meaningless.
Fortunately, we have a BDSM queen in our team.
She thought of techniques in SM to check how pain it is to the slave, and use the same trick to check how the servee's body can feel.
I have to emphasize: that was not a medical treatment, that was about communication with each other.
They were talking about the feeling of two people, instead of the body of one person.
The whole process relies on the intimacy between the sex volunteer and the servee.

[[slide page 11]] ND
"Strolling" for him was from his room to the front door of his home.
Uh, I'm not talking about he lives in a big house.
Though using an electric wheelchair, ND's finger was not powerful enough to control the device for more than 10 minutes,
which means going out alone is not possible for him.
But after applying for our service, he trained himself to "walk" longer.
Even after our service, we were told that he kept trying to leave home and meet other friends.

Another servee has tried other entertainment such as snorkeling and paragliding after our service.
He's having a more plentiful life than before, and even than me.

[[slide page 12]]
In these cases, we can see that:
First, physical orgasm is not the only purpose of a sexual service.
Secondly, libido, or desire for sexual activity, is a strong energy for people to live.

There's a continuing question for us: People can still live without sex.
[[slide page 13]]
What's so important for disabled people to have sex?
Well, I think sex is probably not important for those who can have sex easily, but the impossibility to sex or intimacy may deny the self-esteem of a person.
Sex is an important reason for most people to make friends. So on the other hand, once a person is forced to abandon the opportunity to have sex, she (or he) might lose the energy to social activities. And that's not good for mental health.

[[slide page 14]] The 3 aspects we care about
First, physical orgasm. This is not only about sex organ, but also those come from your erogenous zone.
The problem is not only that people don't know how to interact with disabled people during sex,
but also that people do not want to know how the sex would be for people with different disabilities.

Second, intimacy. The right to have a satisfying date is also important.
Let's imagine, what if a couple of lovers want to kiss each other while seeing movie in a theater, but one of them is in wheelchair so their positions are actually separated?

Third, social integration. Many people with disabilities don't have enough opportunity to make close friends. One of the reasons is that other people usually don't know how to react with disabled people. Therefore, education is important.

[[slide page 15]] Gender Equity Education
In Taiwan, gender equity education comprises 3 parts: affective education, sex education, and gay and lesbian education.
Though I also want to introduce the situation that the conservative group is raising a proposal of referendum to forbid gay and lesbian education, but that's not the issue here so I have to skip that. I hope people who are interested in Taiwan may notice that same-sex marriage is not the only issue about gender equity.

Uh, back to disability rights movement.
As an organization which cares both gender issue and disability issue, we note that even open-minded gender activists may ignore the existence of people with disabilities.
Gender equity education is never designed or applied in the point of view of the disabled.
For example, there are some materials for teaching safe sex, but people seldom think about how a blind person should know before she (or he) masturbate or have sex.

We have a servee who once masturbated in the bathroom of his home, but couldn't clean up since not knowing where his semen reached during ejaculation, and therefore shocked his sister who later used the bathroom.
And another friend bought an artificial vagina in a sex toy store. But he didn't even know he have to erect before insertion.

[[slide page 16]] female servee
People caring about gender equity keep question us: why is there only one female servee during these 5 years after our foundation?
Well, we think the answer is complicated. But the most important one is: how difficult for a female to "confess" she has sexual desire?
We all know about "slut shaming", and those terms to humiliate females by their sexuality -- such as "bitch" and "whore".
It's difficult even for able-bodied females to state their sex experience and preference.
Then it's even more difficult for disabled females to think what she herself wants.

But before sexual activity with other people, disabled females don't even know their body well.
The only female servee we have, told us she has never seen or touched her own vagina.
So we also hosted some conferences and speeches to discuss about such situation of disabled females.

[[slide page 17]] Androcentrism
This is an important issue for us. And I think it's important for those who care about sexual health of disabled people.
Though there are some textures talking about sexual desires of disabled females. To provide sexual service or even sex education to them is barely seen.
I have to admit that, even though there are more and more female members joining us, androcentrism is still not easy to get over.

[[slide page 18]] limitations
Hand Angel provides service to those with servere physical or visual disabilities.
So here comes a frequently asked question: what about others?
The main difficulty for us is that we don't know enough about the situation of other disabilities.
Of course we know that people with other disabilities also don't have enough sexual resources,
but we ourselves do not have enough resources to share, either.
That's why we also hope other people to compose other similar organization.

Meanwhile, there are some people we cannot help because of law.
Adolescents are the ones I myself care about most,
since male teenagers have overwhelming sexual desire, and that would be hell for those with upper limb disability.

However, there are always laws prohibiting youths to have sex in every country.
[[slide page 19]]
In Taiwan, it is legal to have sexual activity after 16. No matter it's intercourse or not.
But even for an organization providing free service like us, the member who communicate with sex volunteer and the servee would be punished as a broker if the servee is younger than 18.
Actually, we do have an applier who mailed us about his desire when he was 15. What we can do is tell him to wait 3 more years.

Unfortunately, being an adult does not mean your right to sex is permitted.
[[slide page 20]]
People with intellectual disability or mental disorder are also infantilized, treated as babies or angels, and considered asexual.
The dilemma is similar to what teenagers have. Their consents are not considered valid.
That is frustrating. The law to protect them from sexual violence also tortures them.

[[slide page 21]] Acrotomophilia and devotees
While talking about disabled people in love or having sex, this is also an issue we should mention.
Some people worry about that devotees are just trying to dominate or take control of the disabled people.
This is similar to MacKinnon's dominance theory and male supremacy.
Devotees are considered to have more power in the relationship, and thus disabled people have a lack of autonomy.

I think that's a stigma, too.
The dominance theory does not deny free love. It focuses on the power issue.
Thus, the problem lies still on the absence of resources disabled people deserve.
Slanders on devotees are based on the prejudice that disabled people are never sexy,
and that denies the possibility for disabled people to have plentiful sexual activity.
The whole society shall support disabled people to have their own autonomy in their relationship.

[[slide page 22]] Difficulties
Usually, people would understand sexual desire of disabled people.
But to support it publicly is another story, especially for the organizations relying on donations.
There are some social workers and parents telling us that they want to do something to help their cases and family,
but it is still an issue which could not be spoken.
It's never been easy for us to talk about sex on the table, but it should be done.
Even for those who don't agree with the idea of sexual service, I do hope you could at least support disabled people to talk about their sex and romance.

[[slide page 23]]
This ends my report. Thank you for listening.
I'm Kong, a sex volunteer of Hand Angel from Taiwan.

「世界為我開啟，讓你帶我遊歷」
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

世界上的語言有兩種——「無聲與有聲」。
無聲的語言，需要開啟心眼，用心感受傳遞，
有聲的語言，需要開啟想像，大膽努力練習。

做為一位外景主持人，我相信除了流暢的口條，更重要的是，用心去閱讀體會那藏在深邃眼裡、銀白髮髻、交織掌紋間的無聲語言。八年，兩千九百多個日子裡，我搜集了如繁星點點的故事與感動，閃閃亮晶晶地在我心中的小宇宙。默願著有那麼一天，我一定要站上世界的舞台，與大家分享這些亮光，分享台灣的美好。

我很感恩雖然沒有大紅大紫，但一路上滿滿是貴人與奇蹟。今年我接下了一個新節目，我將帶著五大洲12位外國朋友來認識台灣與客家文化，此時，有聲語言變得十二萬分重要，曾經短暫擔任過國小英文老師的我，用英語來表達並不陌生，但是要更精進絕對需要更有系統的學習，謝謝 TutorABC 為我開啟了新的學習大門，透過線上課程，我可以隨時隨地進入學習的情境中。

於是這天我來到美麗的北海岸邊，開始我的第一堂英文課，熱愛大自然的我，也能藉此忙裡偷閒，更重要的是，終於有這機會我能帶外國朋友看看台灣的美了！

Teacher Madison住在英國劍橋，透過螢幕鏡頭，我看見她教學的熱情與喜悅，我也藉著簡單的英文語句，跟她說此時我在這太平洋的寶島上，那海有多藍，那陽光的味緒多和煦，那礫石的觸感有多親膚，那男女老少有多熱情。

我選擇戶外活動的課程單元，課前TutorABC會先提供課程內容，讓我可以提早預習。上課過程中，Madison先帶我認識每個單字的解釋，再藉由生活經驗的分享，引導我自在地用英語來表達，最後的學習評鑑也順利地將我的學習進度完整紀錄！

我們說說笑笑，也用英文交換彼此眼前的美好景物，有幾度我眼眶紅紅，也許是橘紅夕陽映眼的關係吧，當她說起受教育的過程中，她一直都知道太平洋上有一個美麗的寶島，叫作「Formosa Taiwan」，而她也一直期待著有天能夠來台灣旅行，我們靜默了幾秒，同聲說——
So glad to meet you here today through
TutorABC！

“You opened my door to the world, and accompanied me on this global journey”


There are two kinds of languages; one is conveyed by sound while the other one is utterly silent. The “silent” language is perceived by an observant and open heart. On the other hand, a language with sound requires a wild imagination and relentless training.

As an outdoor TV host, I believe that what matters, besides speaking eloquently, is to read between the lines and to be aware of the stories in our elder’s eyes, silver hair buns, and intertwined fingerprints. During the past 8 years of my career, I collected a plethora of anecdotes, and they are just like sparkling stars in my little universe. I hope someday I can stand in front of a big crowd and show everyone these stars, which represent the gifts of Taiwan.

I am eternally grateful for those heroes and miracles along the way, even if I didn’t make it big. This year, I am hosting a new TV program. I will introduce Taiwanese and Hakka culture to twelve foreign friends from five continents. Because of this, my language skills are crucial to the success of the program. I am familiar with communicating in English since I have been an elementary school English teacher. However, in order to reach a higher level of proficiency, I need to learn in a more systematic and organized way. Thanks to TutorABC, I found a new gateway to learning, and through their online courses, I can always start learning regardless of time and space.

So, one day I came to the gorgeous northern coast, and started my first English class. As a nature lover, I can also release my stress from work. Not to mention, I finally had the chance to introduce my foreign friends to the beauty of Taiwan and its natural scenery.

Ms. Madison, my teacher, lives in Cambridge, United Kingdom. Via the camera of her computer screen, I saw her joy and enthusiasm in teaching English. With a few simple English sentences and phrases, I described the sight of this gifted island on the Pacific Ocean: the azure sea, the blazing sun, the textured rocks, and the elated people.

I chose the course related to outdoor activities. Before class, TutorABC will provide me with course material for previewing. During class, Ms. Madison will introduce the definition of the words, and encourage me to use those words to share my stories and experiences. Before the class ends, a learning assessment will be conducted to record my current progress.

We chatted, laughed, and used English to share the breathtaking view in front of us. Occasionally, my eyes were slightly red, probably due to the orange sunset that projected onto my eyes. Ms. Madison talked about her school years, and how she always knew that there is a beautiful island named “Formosa Taiwan” on the Pacific Ocean. She always looked forward to visiting Taiwan. After a few seconds of silence, we said to each other simultaneously, “So glad to meet you here today through TutorABC!”

Learning a new language can be very joyful and rewarding, if we are willing to forget all the excessive concerns and recollect the pure enthusiasm of learning our mother tongue from adults when we were still children. TutorABC can help us find back that motivation for learning language, but first, we ask you to open your mind, observe with your heart, and learn without fear!

Huawei is preparing to launch its next flagship the P11 in February and first leaked firmware files suggest a surprise is on the way. According to XDA Developers, the Chinese manufacturer is going to introduce the phone with a notch on the front screen, similar to what we’ve seen in the iPhone X, Essential PH-1, and Sharp Aquos S2.
The overlay image comes from a reference in a configuration file that defines the “RoundCornerDisplay”. Multiple files are associated with this definition, all of them appearing to assist in avoiding drawing over parts of the screen to accommodate the unique display.
Another file has the word "notch" in its name “ro.config.hw_notch_size” with the value set to “258,84,411,27”. It might represent left, top, right and bottom offsets in moving screen content.

With the new screen, Huawei might introduce a new 2240 x 1080 resolution. The device will have a 6.01” Samsung-made 2160x1080 pixel LCD, so it would be interesting to see how the manufacturer will implement the extra pixels on top.

原文
Hitachi Cable Announces the Release of Active Optical HDMI Cables Suitable for Extended Distances

TOKYO--(BUSINESS WIRE)--Hitachi Cable, Ltd. (TOKYO:5812) has announced the development and release of extended distance Active Optical HDMI cables (Note 1) which transmit image signals such as full HD (Note 2), 3D, and 4K2K (Note 3) through optical fibers for digital signage. Sales of this product will start in June.

Digital signage, in which large format high definition thin displays are used as signboards, has become common in recent years in public and commercial facilities. The cables used in digital signage must be compatible with high speed interfaces such as HDMI in order to display high resolution images. Unlike ordinary consumer household metal HDMI cables that have short transmission lengths of 10 meters or less, commercial signage applications require long transmission distances, and in some cases requires UL Plenum rated cable.

In order to respond to such needs, Hitachi Cable has developed long and thin Active Optical HDMI cables which transmit full HD image signals via optical fibers, and will introduce them to the market in June.

The Active Optical HDMI cable being released has a built-in photoelectric converter in the connector. Hitachi Cable developed this small photoelectric converter using the active optical component technologies that the company has accumulated through the development of various optical devices; and has mounted it within the connector to realize the same handling as ordinary HDMI connectors.

Hitachi Cable used optical fiber as the high-speed signal wire in the cable, realizing up to 100 meters of transmission distance, and achieved a small outer diameter of 5.9 mm by using a correction circuit for the low speed signal wire to prevent signal attenuation. The cable is also Plenum rated and compliant with the fire resistance standard UL444, which is required in the United States for wiring in spaces with a constant air flow due to air handling, such as under floors in data centers, and plenum areas in commercial buildings.

These features will reduce the procedures and costs of installation work and further promote the use of digital signage.

Hitachi Cable will put even more effort into producing longer and thinner Active Optical HDMI, and other high-speed data cables, to expand the product lineup as quickly as possible.
