Psychosocial Treatment for Drug Dependence

All randomized controlled studies published in international peer-reviewed journals up to July 1999 were meta-analysed with the aim of studying the effect of psychosocial interventions on patients with drug dependence. Systematic literature searches were administered by SBU. In all 104 studies were screened and rated according to the 12 dimension quality score of SBU. The analyses in the chapter s

Analysis of Overrun Strategies in Periodic Control Tasks

The paper considers period overruns in control tasks with variationsin execution time (or response time). A simple model is used, wherethe input and output operations are assumed to be time-triggered,and the execution-time distribution of the task is assumed to beknown. Three overrun strategies, called Abort, Skip, andQueue, are modeled as discrete-time jump linear systems and areanalyzed with reg

An all-digital PLL clock multiplier

A fully integrated digital PLL used as a clock multiplying circuit is designed and manufactured. The PLL has no off-chip components and it is made from standard cells found in most digital standard cell libraries. It is therefore portable between processes as an IP-block. Using a 0.35 μm standard CMOS process and a 3.0 V supply voltage, the PLL has a frequency range of 152 MHz to 366 MHz and occup

Three conceptions of explaining how possibly—and one reductive account

Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three alternative conceptions making how-possibly explanation an interesting phenomenon in its own right. The first variety approaches “how possibly X?” by showing that X is not epistemically impossible. This can sometimes be achieved by removing misunderstandings concerning the

The frail elderly, family network and public home help services : a pilot study of the parties' perception of the help and their reciprocal relationships

The family with the elderly and the home help workers’ team constitute two organisations, which meet in the care work. In this context the family is extended and often constitute not only members from the nuclear family but also other members of the network of relatives, whom take part in the care of the elderly. The extended family may in some cases include four generations (Finch & Mason, 19

Use of environmental value stream mapping and environmental loss analysis in lean manufacturing work at Volvo

Green production systems requires efficient production and low use of resources such as energy, material etc. To achieve this, there is a need for further development of continuous improvement tools in the “lean and green” area. This work deals with environmental value stream mapping (Environmental-VSM), which has been applied in two case studies at Volvo Penta Vara and Volvo Construction Equipmen
