TL;DR: The rules on protecting drones from unlawful interference are promising, although the required security features can also be abused by rogue operators, and reliable and safe means of stopping unlawful drone operations should be employed at critical locations.
Abstract: Civil unmanned aircraft systems, commonly known as drones, have many useful applications but can also be used to intentionally cause harm. Additionally, drones themselves can be subject to unlawful interference. In this article, I analyze how European Union’s new rules on drones affect such security threats. I argue that the rules on protecting drones from unlawful interference are promising, although the required security features can also be abused by rogue operators. The intentional misuse of drones, however, is not much deterred by the rules that seek to protect persons and property from such misuse. Rules concerning the operator and the pilot assume compliance, the mandatory technical safeguards can be circumvented, and oversight is difficult because drones are mostly operated from outside airports in a distributed manner. One way to fill the security gap is to employ anti-drone technology that detects drones and prevents them from entering sensitive airspace without permission. Although many airports have already adopted such technology, the EU should consider making it mandatory for the busiest airports. Regardless of rules enacted by the Union, though, reliable and safe means of stopping unlawful drone operations should be employed at critical locations. This applies also to areas like prisons and power plants, the protection of which falls within the ambit of national security.

TL;DR: It is concluded that in cases where mothers are stalked, professionals in the social and health services, law enforcement, and criminal justice should view the children, too, as victims and construct supportive social relationships for women and children facing threatening life situations.
Abstract: This qualitative study discusses post separation stalking and its implications in children's everyday lives. Based on narratives of 13 Finnish children and 20 women, the research fills a gap in the knowledge regarding the psychosocial, emotional, and physical impacts of stalking on children when their mothers are stalked by a former partner. It identifies four forms of impact: (a) an atmosphere of fear and feelings of insecurity; (b) disguised acts of stalking and the father's performance of care, love, and longing; (c) exploitation of children in stalking; and (d) physical abuse, acts of violence, and threats of death. The findings indicate that stalking severely constrains children's everyday lives and strengthens, yet often distorts, the mother-child bond. The study concludes that in cases where mothers are stalked, professionals in the social and health services, law enforcement, and criminal justice should view the children, too, as victims and construct supportive social relationships for women and children facing threatening life situations.

TL;DR: In this article, the authors discuss Holocene vegetation succession, permafrost dynamics and peat accumulation in the Usinsk mire, located in the Pechora lowlands of Northeast European Russia.
Abstract: This study discusses Holocene vegetation succession, permafrost dynamics and peat accumulation in the Usinsk mire, located in the Pechora lowlands of Northeast European Russia. At present, the area is situated in the extreme northern taiga subzone near the southern limit of permafrost. Reconstructions are based on plant macrofossil analysis, physico-chemical analysis and AMS (accelerator mass spectrometry) radiocarbon dating of two peat profiles investigated in detail. Additional information is available from seven other sites. Organic accumulation started at ca. 11 350 BP (14C yrs). Terrestrialization of ponds was the most common pathway for mire initiation. During a large part of their history, the sites have been Cyperaceae-dominated fens. A change into Sphagnum-dominated ecosystems is recorded at 3700-3000 BP. Permafrost became established around 2300 BP, although first signs of embryonic palsa formation can be tentatively traced back to about 2900 BP. Palsas and peat plateaus have experienced several periods of freezing and entire or partial thawing. The extant permafrost stages are young. The long-term carbon accumulation rate in the investigated sites is 19 g/m2/yr. The average rate of carbon accumulation in the dynamic permafrost stage is 23 g/m2/yr.

TL;DR: In this paper, the authors examined extreme temperature and precipitation under two potential geoengineering methods forming part of the Geoengineering Model-Intercomparison Project (GeoMIP).
Abstract: . We examine extreme temperature and precipitation under two
potential geoengineering methods forming part of the Geoengineering Model
Intercomparison Project (GeoMIP). The solar dimming experiment G1 is designed
to completely offset the global mean radiative forcing due to a
CO2 -quadrupling experiment (abrupt4 × CO2), while in
GeoMIP experiment G4, the radiative forcing due to the representative
concentration pathway 4.5 (RCP4.5) scenario is partly offset by a simulated
layer of aerosols in the stratosphere. Both G1 and G4 geoengineering
simulations lead to lower minimum temperatures (TNn) at higher latitudes and
on land, primarily through feedback effects involving high-latitude processes
such as snow cover, sea ice and soil moisture. There is larger cooling of TNn
and maximum temperatures (TXx) over land compared with oceans, and the
land–sea cooling contrast is larger for TXx than TNn. Maximum 5-day
precipitation (Rx5day) increases over subtropical oceans, whereas warm spells
(WSDI) decrease markedly in the tropics, and the number of consecutive dry
days (CDDs) decreases in most deserts. The precipitation during the tropical
cyclone (hurricane) seasons becomes less intense, whilst the remainder of the
year becomes wetter. Stratospheric aerosol injection is more effective than
solar dimming in moderating extreme precipitation (and flooding). Despite the
magnitude of the radiative forcing applied in G1 being ∼ 7.7 times
larger than in G4 and despite differences in the aerosol chemistry and
transport schemes amongst the models, the two types of geoengineering show
similar spatial patterns in normalized differences in extreme temperatures
changes. Large differences mainly occur at northern high latitudes, where
stratospheric aerosol injection more effectively reduces TNn and TXx. While
the pattern of normalized differences in extreme precipitation is more
complex than that of extreme temperatures, generally stratospheric aerosol
injection is more effective in reducing tropical Rx5day, while solar dimming
is more effective over extra-tropical regions.
