Guest Editorial Special Issue on Security and Forensics of Internet of Things: Problems and Solutions

The Internet of Things (IoT) has experienced significant growth over recent years and Gartner predicts that, by 2020, 21 billion IoT endpoints will be in use. The potential behind widespread usage of small devices capable of collecting, transmitting, or acting upon data has been fueling interest both from industry and academia. Security and forensics are two of the topics facing major challenges in this paradigm, on par with or even more prominent than other computing paradigms. Aspects such as low processing power and small storage capacity of such IoT devices contribute to their typically poor built-in security and forensics capabilities. Their reliance on cloud computing and mobile apps to operate and provide services increases the attack surface, distributing the collection of digital evidence and making reconstruction activities (to answer questions as what, where, when, who, why, and how) harder

Addressing climate change with behavioral science: a global intervention tournament in 63 countries

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions’ effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior—several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people’s initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors

Caterpillars of Siderose marthesia nemesis (Illiger) (Lepidoptera, Nymphalidae, Charaxinae) in cerrado near Brasília, Distrito Federal, Brazil

Caterpillars of Siderone marthesia nemesis (Illiger, 1802) (Nymphalidae, Charaxinae) have been found on Casearia sylvestris Sw. (Flacourtiaceae), during the second half of the rainy season in an area of cerrado near Brasília, Distrito Federal, Brazil. They occurred at very low density and are cryptic at all instars. The pupal stage does not occur on the host plant. Average duration of the pupa under laboratory conditions is 14.4 days
