ln the idealized version of how science is
done, facts about the world are waiting to be observed and collected by
objective researchers who use the scientific method to carry out their work.
But in the everyday practice of science, discovery frequently follows an
ambiguous and complicated route. We aim to be objective, but we cannot escape
the context of our unique life experience. Prior knowledge and interests
influence what we experience, what we think our experiences mean, and the
subsequent actions we take. Opportunities for misinterpretation, error, and
self-deception abound.
Consequently, discovery claims should be
thought of as protoscience. Similar to newly staked mining claims, they are
full of potential. But it takes collective scrutiny and acceptance to transform
a discovery claim into a mature discovery. This is the credibility process,
through which the individual researcher’s me, here, now becomes the community’s anyone, anywhere, anytime. Objective knowledge is the goal, not
the starting point.
Once a discovery claim becomes public, the
discoverer receives intellectual credit. But, unlike with mining claims, the
community takes control of what happens next. Within the complex social
structure of the scientific community, researchers make discoveries; editors
and reviewers act as gatekeepers by controlling the publication process; other
scientists use the newfinding to suit their own purposes; and finally, the
public (including other scientists) receives the new discovery and possibly
accompanying technology. As a discovery claim works its way through the
community, the interaction and confrontation between shared and competing
beliefs about the scienceand the technology involved transforms an individual’s discovery claim into the community’s credible discovery.
Two paradoxes exist throughout this
credibility process. First, scientific work tends to focus on some aspect of
prevailing knowledge that is viewed as incomplete or incorrect. Little reward
accompanies duplication and confirmation of what is already known and believed.
The goal is new-search, not re-search. Not surprisingly, newly published
discovery claims and credible discoveries that appear to be important and
convincing will always be open to challenge and potential modification or
refutation by future researchers. Second, novelty itself frequently provokes
disbelief. Nobel Laureate and physiologist Albert Szent-Gyorgyi once described
discovery as “seeing what
everybody has seen and thinking what nobody has thought.” But thinking what nobody else has
thought and telling others what they have missed may not change their views.
Sometimes years are required for truly novel discovery claims to be accepted
and appreciated.
ln the end, credibility “happens” to a discovery claim—a
process that corresponds to what philosopher Annette Baier has described as the
commons of the mind. “We
reason together, challenge, revise, and complete each other’s reasoning and each other’s conceptions of reason.”

B.价格受价值影响,随供求关系变化而变动
C.价格由价值决定,反映价值并反映供求关系
D.价格由价值决定,受供求关系影响又制约供求关系
【正确分析】商品经济运行中,价值、价格、供求三者关系,有三个层次:第一,价值决定价格,价格变化反映价值的变化。商品价格随着供求关系的变化,围绕价值这个中心上下波动。第二,供求影响价格,使价格与价值不一致,供大于求时,价格会下降,低于价值;供不应求时,价格会上涨,高于价值。所以,价格变化反映供求变化。第三,价格变化反过来影响供求。价格上涨,一般会使需求减少,供给增加;反之,价格下降,一般会引起需求增加,供给减少。因此,本题的正确答案是ACD选项。
【干扰分析】B选项价格是受价值决定而不是影响。因此,B选项错误。
A.多见于青中年男性
B.多有咽干咽痒
C.咽部症状与情绪有关
