- As recovering the crust-mantle/Moho density contrast (MDC) significantly depends on the properties of the Earth's crust and upper mantle, varying from place to place, it is an oversimplification to define a constant standard value for it. It is especially challenging in Antarctica, where almost all the bedrock is covered with a thick layer of ice, and seismic data cannot provide a sufficient spatial resolution for geological and geophysical applications. As an alternative, we determine the MDC in Antarctica and its surrounding seas with a resolution of 1 degrees x 1 degrees by the Vening Meinesz-Moritz gravimetric-isostatic technique using the XGM2019e Earth Gravitational Model and Earth2014 topographic/bathymetric information along with CRUST1.0 and CRUST19 seismic crustal models. The numerical results show that our model, named HVMDC20, varies from 81 kg m(-3) in the Pacific Antarctic mid-oceanic ridge to 579 kg m(-3) in the Gamburtsev Mountain Range in the central continent with a general average of 403 kg m(-3). To assess our computations, we compare our estimates with those of some other gravimetric as well as seismic models (KTH11, GEMMA12C, KTH15C and CRUST1.0), illustrating that our estimates agree fairly well with KTH15C and CRUST1.0 but rather poor with the other models. In addition, we compare the geological signatures with HVMDC20, showing how the main geological structures contribute to the MDC. Finally, we study the remaining glacial isostatic adjustment effect on gravity to figure out how much it affects the MDC recovery, yielding a correlation of the optimum spectral window (7 <= n <= 12) between XGM2019e and W12a GIA models of the order of similar to 0.6 contributing within a negligible +/- 14 kg m(-3) to the MDC.

Tidskriftsartikel (refereegranskat)abstract
- In this research, we present a local Moho model, named MOHV19, including Moho depth and Moho density contrast (or shortly Moho constituents) with corresponding uncertainties, which are mapped from altimetric and gravimetric data (DSNSC08) in addition to seismic tomographic (CRUST1.0) and Earth topographic data (Earth2014) to a resolution of 1 degrees x 1 degrees based on a solution of Vening Meinesz-Moritz' theory of isostasy. The MOHV19 model covers the area of entire European plate along with the surrounding oceans, bounded by latitudes (30 degrees N-82 degrees N) and longitudes (40 degrees W-70 degrees E). The article aims to interpret the Moho model resulted via altimetric and gravimetric information from the geological and geophysical perspectives along with investigating the relation between the Moho depth and Moho density contrast. Our numerical results show that estimated Moho depths range from 7.5 to 57.9 km with continental and oceanic averages of 41.3 +/- 4.9 km and 21.6 +/- 9.2 km, respectively, and an overall average of 30.9 +/- 12.3 km. The estimated Moho density contrast ranges from 60.2 to 565.8 kg/m(3), with averages of 421.8 +/- 57.9 and 284.4 +/- 62.9 kg/m(3) for continental and oceanic regions, respectively, with a total average of 350.3 +/- 91.5 kg/m(3). In most areas, estimated uncertainties in the Moho constituents are less than 3 km and 40 kg/m(3), respectively, but they reach to much more significant values under Iceland, parts of Gulf of Bothnia and along the Kvitoya Island. Comparing the Moho depths estimated by MOHV19 and those derived by CRUST1.0, MDN07, GRAD09 and MD19 models shows that MOHV19 agree fairly well with CRUST1.0 but rather poor with other models. The RMS difference between the Moho density contrasts estimated by MOHV19 and CRUST1.0 models is 49.45 kg/m(3).

Quality of nursing care as perceived by cancer patients : A cross-sectional survey in four European countries
- 2017
-
Ingår i: Journal of B.U.ON.. - 1107-0625. ; 22:3, s. 777-782

Forskningsöversikt (refereegranskat)abstract
- Purpose: To explore and compare cancer patients' perceptions on the quality of nursing care in four European countries. Methods: Data were collected in Cyprus, Finland, Greece and Sweden. The sample comprised 596 hospitalized cancer patients. The quality of nursing care was measured using the “Oncology Patients' Perceptions of the Quality of Nursing Care Scale” (OPPQNCS). Patient characteristics were also collected. Analysis of variance was used to examine the effects of country on the perceptions of the quality of nursing care. Results: Patients' age ranged from 18 to 86 years, and 58% were male. The comparison of cancer patients' perceptions regarding the quality of nursing care between the four countries showed a statistically significant difference in the total OPPQNCS scores (p<0.001) as well as in the subscales responsiveness (p<0.001), individualization (p<0.001), coordination (p<0.001) and proficiency (p<0.001). The Cronbach's alpha coefficient for the OPPQNCS ranged between 0.89 and 0.95. A multivariate analysis of variance for the OPPQNCS controlled by respondents' demographic characteristics revealed that only the patient's country was significantly related with the patients' perceptions of quality care. Conclusion: Quality of nursing care as perceived by cancer patients was high, but differed between the four countries. The impact of the clinical status of cancer patients on the quality of nursing care and managerial factors such as staffing/nursing care delivery models that influence the ability of nurses to offer high quality care should also be explored by more focused studies.

De gode viljers land : En venstrefløjskritik af multikulturalismen som svensk statsideologi
- 2018
-
Bok (populärvet., debatt m.m.)abstract
- Multikulturalisme ses af mange som progressiv og venstreorienteret, og kritikken af den betragtes som reaktionær og racistisk. Denne bog udfordrer denne tankegang og viser – fra et venstrefløjsperspektiv – hvordan den moderne mangfoldighedstankegang tværtimod undergraver fornuft, frihed, lighed og individuel selvbestemmelse. Ved at have et særligt fokus på sær-identiteter og indføre grupperettigheder på bekostning af universel politisk frihed, borgerrettigheder, upartiske institutioner og lighed mellem kønnene er den på kollisionskurs med demokratiets grundværdier. Multikulturalisme er derfor i virkeligheden en konservativ og antimoderne ideologi.

Migrants and Crime in Sweden in the Twenty-First Century

Tidskriftsartikel (refereegranskat)abstract
- In 2005, the Swedish Crime Prevention Agency published a report about the link between immigration and crime. Since then, no comprehensive study has been conducted even though Sweden has experienced a large influx of migrants in combination with a rising crime rate. This study conducted by Goran Adamson and Tino Sanandaji is the first purely descriptive scientific investigation on the matter in fifteen years. The investigation (from 2002 to 2017) covers seven distinct categories of crime, and distinguishes between seven regions of origin. Based on 33 per cent of the population (2017), 58 per cent of those suspect for total crime on reasonable grounds are migrants. Regarding murder, manslaughter and attempted murder, the figures are 73 per cent, while the proportion of robbery is 70 per cent. Non-registered migrants are linked to about 13 per cent of total crime. Given the fact that this group is small, crime propensity among non-registered migrants is significant.

Multikulturen och högerpopulismen
- 2016
-
Ingår i: Kvartal.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Den multikulturella vänstern har brutit med klassiska vänsterideal som vetenskap, sekularism, anspråk på sanning och fri debatt. Den förkastar högerns nationalism men odlar en etnomystik som är minst lika konservativ. Kulturell självbelåtenhet hånas och hyllas på samma gång. Var finns principen?...
