Large-scale star formation in disk galaxies is hypothesized to be driven by global gravitational instability. The observed gas surface density is commonly used to compute the strength of gravitational instability, but according to this criterion, star formation often appears to occur in gravitationally stable regions. One possible reason is that the stellar contribution to the instability has been

Psychological disability caused by stress is likely to affect cognitive and emotional functions, such as memory, attention, concentration, and decision making. These functions are essential in a train driver’s work, who is responsible for his or her own and others’ safety, and for this purpose requires optimal work capacity. Eighteen train drivers, 40 – 56 years old, most of them with long work ex

Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. For many channel codes, optimal decoding with traditional methods is prohibitively complex. The challenge therefore lies in designi

Popular Abstract in Swedish Regimskiftet 1965-1966 i Indonesien åtföljdes av en massaker på kommunister och vänstersympatisörer, varvid uppskattningsvis 1/2 miljon människor fick sätta livet till. Ytterligare 100.000-tals personer internerades i över ett decennium, somliga så länge som 30 år utan att deras sak blev prövad i en rättegång. Andra blev summariskt avrättade. Så sent som på 1990 talet vStarting from Theodor Adorno´s assertion that art is negative knowledge of the real world, the book analyses Indonesian literature produced during the New Order which deal with the events of 1965-1966 and its consequences. A number of Indonesia´s best known authors have written on the subject. The central issue raised is the extent to which this literature has contributed to undermining and thereb

Del III lyfter fram de två vanligt förekommande, men oftast helt okända, växtsläktena fibblor och maskrosor. Här kombineras bestämningsflorans beskrivningar och avbildningar med landskapsflorans beskrivningar av växtplatser och utbredningar, alltid med noggranna kartor. Samtliga 70 fibblor är vackert tecknade och 149 olika maskrosor är avbildade.

One major problem for integrating study results into a common body of knowledge is the heterogeneity of reporting styles: (1) It is difficult to locate relevant information and (2) important information is often missing. Reporting guidelines are expected to support a systematic, standardized presentation of empirical research, thus improving reporting in order to support readers in (1) finding the

Weaver och Lahtinen diskuterar betydelsen av övergången från analog till digital teknik i Storbritannien och exemplifierar utredningspotentialen med identifierandet av gärningsmännen i terrorattentaten i London 2005 och deltagare i upploppen 2011. Weaver och Lahtinen pekar här på ett från andra samhällsfrågor välbekant fenomen, att framtida användning av system diskuteras med utgångspunkt från forAn overview and critical discussion of the research on the crime prevention effects of camera surveillance. The authors argue that much of extant research is too focused on specific contexts that are hard to generalise to other countries, environments and settings. Previous research has also largely been done within the context of older, analog surveillance systems, which fails to take into accoun
