Three approaches to trend analysis of water quality time series are discussed: (1) seasonal model, with a test for trend based on ranks of observations, with observations assumed to be m dependent; (2) transfer function noise model, in which covariate series may be included by means of transfer functions, with the remaining noise modeled as a seasonal autoregressive moving average process; and (3)

A new method for identifying and ranking critical components and sets of components in technical infrastructures is presented. The criticality of a component or a set of components is defined as the vulnerability of the system to failure in a specific component, or set of components. The identification of critical components is increasingly difficult when considering multiple simultaneous failures

The development of science parks constitutes an interesting example of policy to enhance the technology-based development of a region. These parks, it is argued, contribute to fostering technological innovation and transfer and stimulating the growth of high-level economic activities. This article examines the role that science parks play in the promotion of regional development with particular re

Syftet med artikeln är att utforska och förstå beskrivningar av och information om HPV-prevention utifrån olika positioner för att fånga samhälleliga och kulturella innebörder av HPV-vaccin. Två skolsköterskor intervjuades om sitt arbete med HPV-vaccinering, mediematerial om HPV-vaccin hämtades från Dagens Nyheter, Svenska Dagbladet och Sydsvenskans online-arkiv och informationsmaterial hämtades f

Hälsopsykologi är ett ungt, dynamiskt och snabbt växande forsknings-, utbildnings- och tillämpningsområde. Hälsopsykologin är relevant för praktiskt taget allt som har med hälsa och sjukdom att göra. I flera ämnesområden, som medicin, rehabiliterings- och vårdvetenskap, har hälsopsykologiska teorier, t.ex. om stress och stresshantering, integrerats och praktiserats. Hälsopsykologen som forskare st

Centralized Petersen coil earthing in networks with extensive use of underground cable involves flow of large quantities of reactive earth fault current. In networks with long radial cable feeders this creates problems involving active losses and active and reactive earth fault current. One possible solution to the problem is the use of local compensation. This paper aims at understanding the limi

Attracting membership while stifling freeriding and heterogeneous preferences among potential members is critical for trade union success. Women are generally seen as less inclined to join trade unions, particularly at the onset of the labor movement. We highlight a previously neglected explanation for this: the importance of risk and gender differences in assessment hereof. We study matched emplo
