American medicine, at its best, is the envy of the world.

 

"A Scientific Revolution

By Ralph H. Hruban and Will Linder

Pegasus, 311 pages, $29.95

Grounded in research and cultivating inquiry, American medicine, at its best, is the envy of the world.

Patients from around the globe -- with the means to afford it -- travel to centers of excellence like the Massachusetts General Hospital and the Cleveland Clinic seeking the latest in clinical care.

 Yet a mere century and a half ago, American medicine was principally guided by hoary tradition, not evidence and exploration; medical schools were little more than for-profit trade schools, populated by young men "too stupid for the Bar" and "too immoral for the Pulpit," as one critic put it. The transformation of American medicine into the science-driven discipline we know today is largely attributable to a single institution, Baltimore's Johns Hopkins University School of Medicine, and to the women and men who breathed life into it. Their stories form the center of "A Scientific Revolution," an uplifting if gauzy collection of biographical vignettes by Hopkins pathologist Ralph Hruban and writer Will Linder, both affectionate Hopkins alumni.

The Johns Hopkins Medical School first opened its doors in 1893, 17 years after the university itself. Its leader was an innovative pathologist, William Welch, who had been attracted by the chance to "develop my field in Baltimore unhampered by traditions." His laboratory, we learn, was uncommonly inclusive, welcoming women as well as men. Clinical medicine at Hopkins was headed by the brilliant, quotable William Osler, "generally regarded as the greatest physician North America has produced," according to the authors.

Osler taught students that medicine was "an art, not a trade; a calling, not a business."

He emphasized the need for showing respect to both patients and colleagues and urged students to compare clinical observations and pathological findings, the better to understand the origins of disease.

He taught at the bedside, explaining that "the best book in medicine is the book of Nature, as writ large in the bodies of men," and encouraged his trainees to "listen to the patient, he is telling you the diagnosis."

The sketches drawn by Dr. Hruban and Mr. Linder can feel like cinematic shorthand. We meet John Shaw Billings, the indefatigable military surgeon whose drive to organize medical information led directly to today's National Library of Medicine and the extensive PubMed database; his devotion to work at the expense of family, we learn, left his son embittered. There is William Halsted, who championed the use of opioid painkillers in surgery and, in the process, fell victim to a devastating addiction. Vivien Thomas, an African-American surgical technician, helped devise many of the operations and instruments used by Alfred Blalock, Hopkins's chief of surgery; yet Thomas was rarely included as a co-author on scientific papers and was invited to the departmental parties that Blalock hosted only as a waiter or bartender, never as a guest.

The most striking vignettes in "A Scientific Revolution" present three determined women whose shared struggles offer a disquieting social portrait of late 19th-century America. We first meet Mary Elizabeth Garrett, who was denied college admission to Hopkins in 1876 after Daniel Coit Gilman, the university's president, determined that women shouldn't be "exposed to the rougher influences" on campus. After Garrett inherited a fortune from her father, a railroad executive, she met twice monthly with a group of like-minded women from other prominent Baltimore families to advance equality in education. In the late 1880s, they saw their chance: Hopkins planned to open a medical school yet was running low on funds. Garrett and her confederates offered to provide the resources -- if the medical school would admit women on equal terms with men. Gilman declined at first but ultimately accepted her terms.

Changing the culture of medicine proved even more challenging than altering admission criteria. Dorothy Reed was a student in the fourth class at Hopkins, one of only 14 women. She had attended Smith as an undergraduate and discovered biology. To pick up the additional science she needed to be considered for Hopkins, she took classes at MIT, where her classmates, the authors tell us, would stand when she came into the room "out of respect for her delicate nature" yet apparently "had no qualms about stealing her laboratory equipment and sabotaging her experiments." The day Reed arrived in Baltimore, a man followed her from the streetcar, asked if she was going to medical school and then told her: "Don't. Go home." Yet that same man -- who turned out to be William Osler, the physician in chief -- would in time become one of her greatest advocates. Reed went on to study Hodgkin's lymphoma in William Welch's pathology lab, identifying the cancer's signature cell, which still bears her name. Even so, she was denied a faculty appointment and had to resume her career elsewhere.

A quarter century later, progress for aspiring female doctors remained agonizingly slow. Helen Taussig, the daughter of a prominent Harvard economist, graduated from Berkeley in 1921 and yearned for a career in medicine, but Harvard Medical School was still male-only. Her father suggested public health; the dean of the Harvard School of Public Health told her that she was welcome to enroll but could not earn a degree. When she asked who would accept those terms, he replied: "No one, I hope." She eventually found her way to Hopkins, where she graduated but was denied an internship: There was space for only one woman and a classmate had a slightly higher grade average. She instead pursued research and pediatrics. Her insights into the origins of "blue baby" syndrome, resulting from congenital anomalies of the heart, led to a collaboration with Alfred Blalock and Vivien Thomas and to the development of an operation that, as the authors note, would transform "the lives of hundreds, if not thousands," of afflicted children.

Dr. Hruban and Mr. Linder's portraits capture an inflection point in American medicine: the ambition and excitement of it, the sense of moment experienced by those who were leading the revolution. The opportunity "to have seen a new birth of science, a new dispensation of health," as Dr. Osler marveled, "is not given to every generation."

Kaip aptikti netikrus atsiliepimus „Amazon“

  „Amazon“ padavė į teismą daugiau, nei 10 000 „Facebook“ grupių administratorių, kurie, jos teigimu, koordinavo netikras apžvalgas prekybos milžino platformoje. Nors „Amazon“ administratorių neįvardijo, bendrovė nustatė vieną grupę, pavadintą „Amazon Product Review“, kuri, jos teigimu, buvo daugiau, nei 43 000 narių.

 

    Visur, kur yra apžvalgų – apie programas, restoranus, produktus – taip pat yra manipuliavimo. „Amazon“, kaip didžiausias šalies internetinis mažmenininkas, yra greičiausiai vieta, kur jo rasite. Dauguma jos produktų gaunami iš programos „Marketplace“, kurioje milijonai trečiųjų šalių pardavėjų konkuruoja dėl visko, nuo USB kabelių iki vejos baldų. Netikros apžvalgos gali padėti pardavėjams įgyti pranašumą, vadinasi, tie pigūs „penkių žvaigždučių“ be vardo produktai, kuriuos perkate, o tada norėtumėte, kad to nebūtume nupirkę.

 

    Trečiųjų šalių pardavėjai prieštarauja Amazon taisyklėms mokėti arba motyvuoti žmones nemokamais produktais arba kompensacija grynaisiais. Tačiau daugelis tai daro ir vengia aptikimo, koordinuodami veiksmus tokiose platformose, kaip „Facebook“. „Facebook“ patronuojančios įmonės „Meta“ atstovė sakė: „Grupės, kurios prašo arba skatina netikrus atsiliepimus, pažeidžia mūsų politiką ir yra pašalinamos. Šiuo klausimu bendradarbiaujame su „Amazon“ ir toliau bendradarbiausime visoje pramonės šakoje, kad išspręstume netikrus atsiliepimus.

 

    „Amazon“ teisinis veiksmas yra žingsnis, siekiant sumažinti netikrų atsiliepimų savo platformoje. „Proaktyvūs teisiniai veiksmai, nukreipti prieš blogus veikėjus, yra vienas iš daugelio būdų, kaip apsaugoti klientus, patraukiant blogus veikėjus atsakomybėn“, – pranešime spaudai sakė Dharmeshas Mehta, „Amazon“ viceprezidentas, prižiūrintis klientų pasitikėjimą.

 

    Tačiau tai nesibaigianti „Amazon“ kova.

 

    Esu rašęs apie tai, kaip kai kurie pardavėjai medžioja klientus, paliekančius neigiamus atsiliepimus, o kiti įdeda įdėklus, reklamuojančius dovanų korteles arba nemokamus produktus mainais už atsiliepimus. Kalifornijos universiteto Los Andžele mokslininkų atliktas tyrimas, paskelbtas liepos 11 d., rodo, kaip produktai su netikromis apžvalgomis turi bendrą apžvalgininkų grupę. Šis baseinas galėtų lengvai pereiti į kitą ryšio kanalą.

 

    „Norime, kad „Amazon“ klientai apsipirktų su pasitikėjimu, žinodami, kad atsiliepimai, kuriuos jie mato, yra autentiški ir patikimi. Štai kodėl mes rimtai vertiname piktnaudžiavimą atsiliepimais ir siekiame, kad mūsų parduotuvėje niekada nepasirodytų netikri atsiliepimai“, – sakė „Amazon“ atstovė. Ji sakė, kad bendrovė sulaukia daugiau nei 30 milijonų atsiliepimų per savaitę ir kad daugiau nei 12 000 „Amazon“ darbuotojų stengiasi užkirsti kelią sukčiavimui ir piktnaudžiavimui, įskaitant netikrus atsiliepimus. „Sustabdėme šimtus milijonų įtariamų netikrų atsiliepimų, kol juos nepamatė klientas“, – pridūrė ji.

 

    Pirkdami internetu, vis tiek turėsite šiek tiek pasižvalgyti apžvalgų skiltyje. Negalite su 100% tikrumu žinoti, ar atsiliepimais buvo manipuliuojama, tačiau akivaizdžiausiems pažeidėjams yra keletas įspėjamųjų ženklų.

 

    Kaip pastebėti manipuliuojamus reitingus

 

    Kai esate „Amazon“ sąraše, po produkto pavadinimu ieškokite nedidelės nuorodos su įvertinimų skaičiumi. Ši nuoroda yra nuoroda į puslapio apačią, kurioje rodoma klientų atsiliepimų santrauka.

 

    Slinkite žemyn iki šios skilties apačios ir spustelėkite „Žiūrėti visas apžvalgas“. Taip pateksite į prietaisų skydelį, kuriame galėsite rūšiuoti atsiliepimus pagal teigiamus arba kritinius įvertinimus, ieškoti atsiliepimų tekste arba filtruoti pagal patvirtintus pirkinius.

 

    Venkite produktų, kurių apžvalgos yra tik penkios žvaigždutės. Bet koks produktas, turintis šimtus ar tūkstančius atsiliepimų, turėtų rodyti sveiką įvertinimų žvaigždutėmis derinį.

 

    Pirmiausia peržiūrėkite vienos žvaigždutės apžvalgas. Atkreipkite dėmesį į bet kokius pasikartojančius paminėjimus apie akivaizdžius defektus. Atsiliepimo informacijos suvestinės išskleidžiamajame meniu „Visos žvaigždutės“ pasirinkite „Tik 1 žvaigždutė“. Jei neigiami atsiliepimai susiję su kažkuo, ko pardavėjas nekontroliuoja, pvz., dėl siuntimo partnerio pavėluoto pristatymo, aš tai praleisiu.

 

    Rūšiuoti pagal naujausią. Skiltyje „Rūšiuoti pagal“ pakeiskite išskleidžiamąjį meniu iš „Populiariausi atsiliepimai“ į „Naujausi“. Tai dažnai suteikia geresnį atsiliepimų derinį ir gali išspręsti naujausias pristatymo ar kokybės kontrolės problemas.

 

    Tiesą sakant, skaitykite atsiliepimus. Tai akivaizdu: ar apžvalgininkai užsimena, kad jie dar neišbandė produkto? Kartą aptikau dėklą naujam įrenginiui, kuris dar nebuvo išleistas, su daugybe teigiamų atsiliepimų! Taip pat patikrinkite datas. Jei daugelis komentarų buvo paskelbti maždaug tuo pačiu metu, tai gali būti manipuliavimo požymis.

 

    Būkite įtarūs dėl teigiamų nuotraukų ir vaizdo įrašų atsiliepimų. Vaizdai gali būti naudingas būdas suprasti produkto dydį ar funkcijas, bet mokamos peržiūros operacijos dažnai reikalauja, kad recenzentai įtrauktų tokią laikmeną. Štai kodėl paprastas vonios kilimėlis gali baigtis minučių trukmės vaizdo apžvalgomis, hiperboliškai giriančiomis jo pliušumą ar spalvą.

 

    Ieškokite raudonų vėliavėlių, pvz., „dovana“ arba „nemokama“. Paieškos lauke („Ieškoti klientų atsiliepimų“) ieškokite atsiliepimų, kuriuose mainais minima dovanų kortelė arba nemokamas produktas, o tai gali reikšti, kad pardavėjas gerina reitingus, naudodamas finansines paskatas.

 

    Patikrinkite, ar nėra sujungtų atsiliepimų. Perskaitykite tekstą, kad gautumėte visiškai skirtingų produktų apžvalgas. Taip pat galite pamatyti, ar yra kitų versijų.  Spustelėkite išskleidžiamąjį meniu „Visi formatai“, kad pamatytumėte kitus produkto variantus. Kai kurie pardavėjai sujungia du skirtingus sąrašus, kad padidintų atsiliepimų skaičių.

 

     Jei sodo žarnos puslapyje matote knygos apžvalgą, venkite to." [1]

 

1. How to Spot Fake Reviews on Amazon

How to Spot Fake Reviews on Amazon

"Amazon is suing the administrators of more than 10,000 Facebook groups it says coordinated fake reviews on the shopping giant's platform. While Amazon didn't name the admins, the company did identify one group, called "Amazon Product Review," which it said had more than 43,000 members.

Anywhere reviews exist -- for apps, restaurants, products -- manipulation exists, too. Amazon, as the nation's largest online retailer, is the likeliest place you'll find it. The majority of its products come from its Marketplace program, where millions of third-party sellers compete to peddle everything from USB cables to lawn furniture. Fake reviews can help sellers get an edge, hence those cheap "five-star" no-name products that you buy then wish you hadn't.

It is against Amazon's rules for third-party sellers to pay or motivate people with free products or cash compensation. Many do, however, and evade detection by coordinating on platforms such as Facebook. A spokeswoman for Meta, Facebook's parent company, said, "Groups that solicit or encourage fake reviews violate our policies and are removed. We are working with Amazon on this matter and will continue to partner across the industry to address fake reviews."

Amazon's legal action is a step toward reducing fake reviews on its platform. "Proactive legal action targeting bad actors is one of many ways we protect customers by holding bad actors accountable," said Dharmesh Mehta, an Amazon vice president who oversees customer trust, in a press release.

But it is a never-ending struggle for Amazon.

I've written about how some sellers hunt down customers who leave negative reviews, and how others include inserts advertising gift cards or free products in exchange for reviews. A study from researchers at the University of California, Los Angeles, published on July 11, shows how products with fake reviews share a common set of reviewers. This pool could easily move to another communication channel.

"We want Amazon customers to shop with confidence knowing that the reviews they see are authentic and trustworthy. That's why we take reviews abuse seriously and aim to prevent fake reviews from ever appearing in our store," an Amazon spokeswoman said. She said the company receives more than 30 million reviews a week, and that more than 12,000 Amazon employees work to prevent fraud and abuse, including fake reviews. "We have stopped hundreds of millions of suspected fake reviews before they were seen by a customer," she added.

You'll still have to do some sleuthing in the reviews section when shopping online. You can't know with 100% certainty whether reviews were manipulated but there are some telltale signs for the most blatant offenders.

How to spot manipulated ratings

When you're on an Amazon listing, look for a small link with the number of ratings, right underneath the product's title. This link is a shortcut to the bottom of the page showing a summary of customer reviews.

Scroll down to the bottom of this section and click on "See all reviews." This will take you to a dashboard where you can sort reviews by positive or critical ratings, search through review text or filter by verified purchases.

Avoid products with only five-star reviews. Any product with hundreds or thousands of reviews should show a healthy mix of star ratings.

Inspect the one-star reviews first. Take note of any repeated mentions of glaring defects. In the "All stars" dropdown in the review dashboard, select "1 star only." If the negative reviews are about something out of the seller's control, such as a late delivery by the shipping partner, I'll give it a pass.

Sort by most recent. Under Sort By, change the dropdown from "Top reviews" to "Most recent." This often offers a better mix of reviews and can surface recent shipping or quality-control issues.

Actually read the reviews. This one's obvious: Do the reviewers mention they haven't actually tried the product yet? I once came across a case for a new device that wasn't out yet, with dozens of positive reviews! Check the dates too. If many of the comments were posted around the same time, that could be an indication of manipulation.

Be suspicious of positive photo and video reviews. Images can be a helpful way to understand a product's size or features, but paid-review operations often require reviewers to include media. That is why a simple bath mat can end up with minutes-long video reviews, hyperbolically praising its plushness or color.

Search for red flags such as "gift" or "free." In the search field ("Search customer reviews"), look for reviews that mention a gift card or free product in exchange, which might indicate that the seller is boosting ratings through financial incentives.

Check for merged reviews. Skim the text for reviews of entirely different products. You can also see if there are other versions of the listing. Click the "All formats" drop down to see other variations of the product. Some sellers merge two different listings to increase the number of reviews.

If you see a book review on a page for a garden hose, steer clear." [1]
