Su Plos One<\/em>, escono tentativi di spiegare perch\u00e9 i ragazzini si rimpinzano di schifezze e vogliono andare da McDonald’s. Il primo (che ho letto) \u00e8 degli olandesi\u00a0Kirsten Bevelander et al.<\/a>,<\/strong> “The Role of Explicit and Implicit Self-Esteem in Peer Modeling of Palatable Food Intake: A Study on Social Media Interaction among Youngsters”:<\/p>\n

Methods<\/em><\/strong>
\nParticipants (N = 118; 38.1% boys;\u00a0M\u00a0age 11.14\u00b1.79) were asked to play a computer game while they believed to interact online with a same-sex normal-weight remote confederate (i.e., instructed peer) who ate either nothing, a small or large amount of candy.<\/em>
\nResults<\/em><\/strong>
\nParticipants modeled the candy intake of peers via a social media interaction, but this was qualified by their self-esteem. Participants with higher ISE adjusted their candy intake to that of a peer more closely than those with lower ISE when the confederate ate nothing compared to when eating a modest (?\u00a0= .26,\u00a0p\u00a0= .05) or considerable amount of candy (kcal) (?\u00a0= .32,\u00a0p\u00a0= .001). In contrast, participants with lower BE modeled peer intake more than those with higher BE when eating nothing compared to a considerable amount of candy (kcal) (? =\u00a0.21,\u00a0p\u00a0= .02); ESE did not moderate social modeling behavior. In addition, participants with higher discrepant or \u201cdamaged\u201d self-esteem (i.e., high ISE and low ESE) modeled peer intake more when the peer ate nothing or a modest amount compared to a substantial amount of candy (kcal) (?\u00a0= ?.24,\u00a0p\u00a0= .004;\u00a0?\u00a0= ?.26,\u00a0p<.0001, respectively).<\/em>
\nConclusion<\/em><\/strong>
\nYoungsters conform to the amount of palatable food eaten by peers through social media interaction. Those with lower body esteem or damaged self-esteem may be more at risk to peer influences on food intake.<\/em><\/p>\n

Mmm… Pi\u00f9 a rischio se i genitori non si accorgono della loro infelicit\u00e0, forse.<\/p>\n

“How Television Fast Food Marketing Aimed at Children Compares with Adult Advertisements” degli americani\u00a0Amy Bernhardt et al.<\/a>,\u00a0\u00e8 un paragone tra la persuasione occulta esercitata sugli adulti e sui bambini, dalle principali catene di fast-food (QSR):
\nMethods<\/em><\/strong>
\nAll nationally televised advertisements for the top 25 US QSR restaurants from July 1, 2009 to June 30, 2010 were obtained and viewed to identify those advertising meals for children and these advertisements were compared with adult advertisements from the same companies. Content coding included visual and audio assessment of branding, toy premiums, movie tie-ins, and depictions of food. For image size comparisons, the diagonal length of the advertisement was compared with the diagonal length of salient food and drink images.<\/em>
\nResults<\/em><\/strong>
\nAlmost all of the 92 QSR children\u2019s meal advertisements that aired during the study period were attributable to McDonald\u2019s (70%) or Burger King (29%); 79% of 25,000 television placements aired on just four channels (Cartoon Network, Nickelodeon, Disney XD, and Nicktoons). Visual branding was more common in children\u2019s advertisements vs. adult advertisements, with food packaging present in 88% vs. 23%, and street view of the QSR restaurant present in 41% vs. 12%. Toy premiums or giveaways were present in 69% vs. 1%, and movie tie-ins present in 55% vs. 14% of children\u2019s vs. adult advertisements. Median food image diagonal length was 20% of the advertisement diagonal for children\u2019s and 45% for adult advertisements. The audio script for children\u2019s advertisements emphasized giveaways and movie tie-ins whereas adult advertisements emphasized food taste, price and portion size.<\/em>
\nConclusions<\/em><\/strong>
\nChildren\u2019s QSR advertisements emphasized toy giveaways and movie tie-ins rather than food products. Self-regulatory pledges to focus on actual food products instead of toy premiums were not supported by this analysis.<\/em>
\nL’autoregolamentazione non funziona, che sorpresa.<\/p>\n

Zoonosi<\/strong>
\nSu mBio<\/em>, i virologi<\/strong><\/a> di PREDICT\/EcoHealth Alliance<\/a> identificano 55-58 nuovi virus solo nel pipistrello Pteropus giganteus <\/strong><\/a><\/em>(<\/em>aiuto, Ilaria torna in laboratorio!) e fanno un po’ di calcoli:
\nWe used a simple extrapolation to estimate that there are a minimum of 320,000 mammalian viruses awaiting discovery within these nine families, assuming all species harbor a similar number of viruses, with minimal turnover between host species. We estimate the cost of discovering these viruses to be ~$6.3 billion<\/strong> (or ~$1.4 billion for 85% of the total diversity<\/strong>), which if annualized over a 10-year study time frame would represent a small fraction of the cost of many pandemic zoonoses.<\/em><\/p>\n

Quarto regno <\/strong>
\nMi fa venire in mente che i virus non sono considerati microrganismi, essendo forme di vita non indipendenti, ma dopo la scoperta del Mimivirus<\/strong><\/em><\/a> se ne son trovati di ancora pi\u00f9 grandi<\/strong><\/a> – parecchio di pi\u00f9 del batterio medio e anche con pi\u00f9 DNA, come il magnifico Pandora<\/em> in copertina un mese e mezzo fa.<\/p>\n
