Djalali\u2019s lawyer intended to appeal against the death sentence during the 20-day period allowed for an appeal. But according to Amnesty International, the Supreme Court clerks failed to provide him with the necessary information to file his defence submission.<\/p>\n

Forse resta una speranza, in Iran i responsabili di Amnesty International sono ancora in libert\u00e0 al contrario di quanto succede in Turchia<\/a>, per esempio.

\nRichard Van Noorden<\/span><\/a><\/span> sfata il “myth of uncitedness”, secondo il quale met\u00e0 delle pubblicazioni scientifiche non sarebbero mai citate, con una rassegna delle ricerche in tema e dei loro limiti, e un’analisi propria:<\/p>\n

\n

To get a better handle on this dark and forgotten corner of published research,\u00a0Nature\u00a0<\/i>dug into the figures to find out how many papers actually do go uncited (explore the\u00a0full data set and methods<\/a>). It is impossible to know for sure, because citation databases are incomplete. But it\u2019s clear that, at least for the core group of 12,000 or so journals in the Web of Science\u00a0\u2014\u00a0a large database owned by Clarivate Analytics in Philadelphia, Pennsylvania\u00a0\u2014\u00a0zero-citation papers are much less prevalent than is widely believed.<\/p>\n

Web of Science records suggest that fewer than 10% of scientific articles are likely to remain uncited. But the true figure is probably even lower, because large numbers of papers that the database records as uncited have actually been cited somewhere by someone.<\/p>\n

Nelle discipline umanistiche, la stragrande maggioranza degli articoli \u00e8 ignorata. In quelle scientifiche anche uno mai citato nella letteratura pu\u00f2 essere influente.\n<\/p><\/div>\n

Nei paper con un citation index elevato invece,\u00a0Sean Gulick et al<\/em>.<\/a>\u00a0 ricostruiscono la storia della “Sabrina Coast shelf” nel Settore Aurora della calotta glaciale in Antartide orientale (EAIS) negli ultimi 50 milioni di anni:<\/p>\n

Our results imply a dynamic EAIS response with continued anthropogenic warming and suggest that the EAIS contribution to future global sea-level projections may be under-estimated.<\/p>\n

Probabile, commenta Sarah Greenwood<\/span><\/a><\/span>, ma servono pi\u00f9 dati.\u00a0Per adesso danno ragione a Jim Hansen – tanto per cambiare…
\nJo Marchant<\/span><\/a><\/span>\u00a0parla di risultati di un trial americano con l’agopuntura, presentati a un simposio 10 giorni fa e subito <\/span>contestati. Aspetterei la pubblicazione.<\/p>\n

\nDana Nuccitelli<\/a>, sul Guardian<\/em>, spiega le ultime ricerche sugli effetti della comunicazione del consenso scientifico in materia di clima, la prima pubblicata da Nature Human Behaviour.<\/em><\/p>\n

Previous research led by Stephan Lewandowsky has shown that informing people about the expert consensus\u00a0increases acceptance of human-caused global warming<\/a>. However, Yale social scientist Dan Kahan has remained unconvinced and\u00a0continues to argue that 97% consensus messaging is polarizing<\/a>\u00a0and therefore counter-productive.<\/p>\n

To test which side is correct, social scientists\u00a0Sander van der Linden, Anthony Leiserowitz, and Edward Maibach<\/a>\u00a0conducted a survey of over 6,000 nationally-representative Americans, of which 934 were conservatives with at least a college degree. […]<\/p>\n

In the control group, college-educated conservatives thought the expert consensus was about 64%, and college-educated liberals put the number at 78% (a 14% partisan gap). After being informed about the actual 97% consensus, the conservative answer increased to 83% while the liberal response rose to around 90% (a 7% partisan gap).<\/p>\n

Dan Kahan non era convinto, quindi<\/p>\n

the authors have just published\u00a0a second paper<\/a>\u00a0in the Journal of Science Communication<\/em> that responds to Kahan\u2019s critiques by including the data addressing those questions. It shows that consensus messaging increased acceptance of human-caused global warming by about 5%, both for the participants as a whole and specifically for college-educated conservatives. Similarly, support for climate policy rose by about 2% across the political spectrum.<\/p>\n

Rif. anche da Carbon Brief, “Why scientists think 100% of global warming is due to humans<\/a>” di Zeke Hausfather<\/p>\n

While there are natural factors that affect the Earth\u2019s climate, the combined influence of volcanoes and changes in solar activity would have resulted in cooling rather than warming over the past 50 years.<\/p>\n

e “Beyond Misinformation: Understanding and Coping with the \u201cPost-Truth\u201d Era<\/a>” del trio Lewandowski, Ecker & Cook:<\/p>\n

Imagine a world that has had enough of experts. That considers knowledge to be \u201celitist.\u201d Imagine a world in which it is not expert knowledge but an opinion market on Twitter that determines whether a newly emergent strain of avian flu is really contagious to humans, or whether greenhouse gas emissions do in fact cause global warming, as 97% of domain experts say they do.<\/p>\n
