- Many instruments have been developed to measure the multidimensional construct of quality of life. One of them has been developed by the World Health Organization (WHOQOL-100) and adapted into different languages and cultures around the world. The authors of this study wanted to assess the measurement properties of the Turkish version of WHOQOL-100, to find out the latent factors underlying quality of life, and to determine the direction and magnitude of the interdependent effects among these factors by using structural equation modeling (SEM). The measurement properties of the Turkish version of WHOQOL-100 scale were assessed on 520 voluntary participants who were immigrants in Stockholm/Sweden. SEM gave us one second-order factor QOL and the five correlated first-order factors labelled: physical, social relations, psychological, environment and independence. In the model for total participants, all the factor loadings were high (ranging from 0.60 to 0.92 except for “sexuality” which was 0.47), indicating a strong association between each of the latent factors and their respective items. In the models which were separately constructed regarding birthplace, the authors found a strong association between each of the latent factors and their respective items. The most substantial possible effect on QOL was psychological domain (0.93), which was larger than physical health (0.84), social relations (0.82), level of independence (0.91) and environment (0.73). The effect of psychological domain on the overall quality of life is greater than those of other domains.

- Many in Europe believe that large numbers of Turkish immigrants have failed to integrate into their host communities. How is ths situation in Sweden? We found that most of the Turkish immigrants felt themselves to be Turkish and Sweden was accepted as a foregin country. Turkish-originated media was followed frequently and strong ties with relatives in Turkey were maintained. Marriage and friendship with native Swedes were not well accepted. We conclude that despite the mulicultural aspects of Swedish integration policies, Turkish immigrants in Sweden were not well integrated and they prefer to live within the boundaries of their segregated, closed, small communities.

- A flexible list sequential πps sampling method is introduced and studied. It can reproduce any given sampling design without replacement, of fixed or random sample size. The method is a splitting method and uses successive updating of inclusion probabilities. The main advantage of the method is in real-time sampling situations where it can be used as a powerful alternative to Bernoulli and Poisson sampling and can give any desired second-order inclusion probabilities and thus considerably reduce the variability of the sample size

- When there is auxiliary information in survey sampling, the design based "optimal (regression) estimator" of a finite population total/mean is known to be (at least asymptotically) more efficient than the corresponding GREG estimator. We will illustrate this by some simulations with stratified sampling from skewed populations. The GREG estimator was originally constructed using an assisting linear superpopulation model. It may also be seen as a calibration estimator; i.e., as a weighted linear estimator, where the weights obey the calibration equation and, with that restriction, are as close as possible to the original "Horvitz-Thompson weights" (according to a suitable distance). We show that the optimal estimator can also be seen as a calibration estimator in this respect, with a quadratic distance measure closely related to the one generating the GREG estimator. Simple examples will also be given, revealing that this new measure is not always easily obtained.
