    China is the US under Trump. Using vaccines which, while home grown, are not as

    on their healthcare system. Very Sad.

    would give a much higher death figure than 60,000--and the virus hasn''t even
    ravaged the countryside yet. That will happen over the next 3-4 weeks as migrant
    workers and others return to their villages to celebrate the Chinese New Year
    on Jan. 21. Due to the backwardness of rural healthcare and the proportionally
    high concentration of elderly people in the countryside, the covid death toll
    in rural China within the next few weeks will be high but will also receive much
    less media attention.

# SetFit with sentence-transformers/all-mpnet-base-v2

This is a [SetFit](https://github.com/huggingface/setfit) model that can be used for Text Classification. This SetFit model uses [sentence-transformers/all-mpnet-base-v2](https://huggingface.co/sentence-transformers/all-mpnet-base-v2) as the Sentence Transformer embedding model. A [LogisticRegression](https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html) instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

1. Fine-tuning a [Sentence Transformer](https://www.sbert.net) with contrastive learning.
2. Training a classification head with features from the fine-tuned Sentence Transformer.

| yes   | <ul><li>'"Xi Jinping, China’s top leader, abandoned his “zero Covid” policy in early December. That policy had kept infections low but required costly precautions like mass testing — measures that exhausted the budgets of local governments."In a recent issue, The Economist magazine reported that China spent ~$250 billion on mass testing during a recent one-year period. The piece also indicated that an unnamed expert suggested that that number was likely to be much lower than the true amount. Even for China, this is a remarkable amount of resources devoted to that aspect of combating Covid. It\'s no wonder President Xi had to finally give up on zero Covid - in all its manifestations, China could no longer afford the strategy.\n'</li><li>'The huge excursions to and from China at the Dawn of 2020 for China\'s lunar year celebration, just after the Wuhan breakout in DEC 2019 and its aftermath of spreading Covid-19 as a wildfire across the globe has a lesson to compare the present situation.China\'s much advertised, the world\'s first stringent drive to eradicate  Covid VIRUS by adopting  "ZERO COVID " policy since 2019 was lifted on DEC,7,2022 after realizing its end point is a fiasco. The reporting 60k fatalities a week before the China\'s lunar year  on 22,JAN,2023 is a caution to the international travelers. Any global viral spread in 2023 shan\'t become a justification for lifting Zero Covid policy and zero testing of the travelers- in and out by China.\n'</li><li>'Ace Not so black and white. China’s “No-COVID”  policy during the early part of the pandemic, albeit draconian and heavy-handed, likely saved tens of thousands of lives.  However, once vaccines became available, China should have 1) adopted Western mRNA vaccines which are more effective at preventing serious illness than the Chinese domestic versions. 2) Begin preparing for a gradual reopening by stockpiling antivirals to protect its most vulnerable citizens. By demonstrating the “superior” Chinese model with the prolonged strict no-COVID policy, President Xi was able to secure his unprecedented 3rd 5-year term.Liberals are against public health policies that are driven by political considerations rather than driven by science.\n'</li></ul>                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
| no    | <ul><li>'Teaching history is, by its very nature, a matter of prioritization and opinion. When it is a mandatory requirement for a high school diploma, the requirement to learn a specific version of history and regurgitate it becomes a form of indoctrination.  DeSantis is an easy target for his opponents (I am one) for obvious reasons, but the challenge remains the same.  What is the version of history that we want to teach our children?  Should the history of black Americans be enhanced?  What about Mexicans ( a largely overlooked group), women, Asians (nary a word about the Chinese Exclusion Act), religious subgroups - the early plight of Catholics, Jewish immigrants, Mormons, Muslims, and the emergence of a non-secular movement?  How would we propose to teach about abortion rights?  Is it the quiet revolution of the unborn or the destruction of rights previously available to women?  The list goes on.  I find articles like this with outrage dripping, reductive, and of little value. A challenge with public schools is that they are an arm of the government.  So, it is hardly surprising that the CEO of the state/legislature would exert influence.  A debate no history is highly valuable but America goes immediately to war with itself and no longer debates\n'</li><li>"David Brook offers an interesting perspective on Biden and America's conduct in the world.Putin, Xi are all crazy people doing crazy things. In contrast, Biden is a steady hand guiding the American ship of the international rule based order.I suppose if I lived in the Washington bubble, I might have a similar view. But I come from a world of anti-imperialist struggle, and my world looks very different.I see the US undermining struggling nations all over the world, most recently in Africa. The ugly American fingerprints are also all over the coups in Honduras, Venezuela, Bolivia and Peru.Cuba is now in its sixtieth year of a crushing US blockade. US military bases now nun from Niger in West Africa, across the continent to Kenya.Active military operations are going on in Somalis, Syria and of course Ukraine.There's no difference between the referendums for autonomy held in Kosovo and the Donbas and Crimea, except that one was sponsored by the US and the other by Russia.According to the UN, world famine this year can be averted for 1.7 billion dollars. In contrast, our military funding for Ukraine is now at 122 billion.Under American leadership, corporations paid out $257bn to wealthy shareholders, while over 800 million people went to bed hungry.So, forgive me if I see Biden's ''steady hand” differently than the NYTimes crowd does.Perspective is everything, and the world looks very different when you see it from the bottom up.\n"</li><li>'LB and what would we do for our neighbors?  What did we do when children were separated from their parents at the border under Trump?   Most of us did nothing.\n'</li></ul> |
