After more than a decade of a virtual standstill, the adoption of temporal data management features has recently picked up speed, driven by customer demand and the inclusion of temporal expressions into SQL:2011. Most of the big commercial DBMS now include support for bitemporal data and operators. In this paper, we perform a thorough analysis of these commercial temporal DBMS: We investigate t...

Ignorance of the culture and traditions of immigrants leads to misunderstanding and is a factor in mental illness among people whose new home seems intimidating as Dr. Farrukh Hashmi, a psychiatrist and a member of the Midlands Race Relations Board, explains. an immigrant was taken to a mental hospital because he was said to have been aggressive, had been shouting at his family, and he had thre...

In this paper we show that in pure exchange economies there exists no Pareto efficient and strategy-proof allocation mechanism which ensures positive consumptions to all agents. We also show that Pareto efficient, strategy-proof, and non-bossy allocation mechanism is dictatorial. We further show that if there exists three agents, then the allocation given by a Pareto efficient, strategy-proof, ...

Amiracarus pliocennatus n. gen., n. sp. is described based on fossils found in Pliocene and Pleistocene clastic sediments in caves of the Slovenian Classical Karst (Kras). Diagnosis and relationships of the new genus are given and relationships within the extant species of the genus are discussed as well as variability and reliability of some characters, used for species differentiation. Amirac...

Over half of HIV infections in the United States occur among men who have sex with men (MSM). Awareness of infection is a necessary precursor to antiretroviral treatment and risk reduction among HIV-infected persons. We report data on prevalence and awareness of HIV infection among MSM in 2008 and 2011, using data from 20 cities participating in the 2008 and 2011 National HIV Behavioral Surveil...

Abstract We present results of repeated absolute gravity and GPS measurements, carried out at Mt. Etna volcano between 2009 2018. Absolute measurements are rarely performed along arrays stations on active volcanoes and, through our unprecedented dataset, we highlight the possibilities this method to track underground mass changes over long time-scales. Analysis residual data ground deformation ...
