The Effect of Medical Treatment of Attention Deficit Hyperactivity Disorder (ADHD) on Foster Care Caseloads : Evidence from Danish Registry Data

- Since the early 2000s, foster care caseloads have decreased in many wealthy democracies, yet the causes of these declines remain, for the most part, a mystery. This article uses administrative data on all Danish municipalities (N = 277) and a 10% randomly drawn sample of all Danish children (N = 157,938) in the period from 1998 to 2010 to show that increasing medical treatment of attention deficit hyperactivity disorder (ADHD) accounts for a substantial share of the decrease in foster care caseloads. According to our estimates, the decline in foster care caseloads during this period would have been 45% smaller absent increases in medical treatment of ADHD. These findings are especially provocative in light of recent research showing ambiguous effects of medical treatment of ADHD. Future research should be attentive to how medical treatment aimed at addressing children's acute behavioral problems could also have a powerful effect on foster care caseloads.

An alternating low band-gap polyfluorene for optoelectronic devices
- 2006
-
Ingår i: Polymer. ; 47:12, s. 4261-4268
-
Tidskriftsartikel (refereegranskat)abstract
- An alternating polyfluorene (APFO) with low band-gap segments. APFO-Green1, was synthesized for use in optoelectronic devices. The low band-gap segment consists of an electron acceptor (A), fenced by electron donors (D). This D-A-D configuration leads to partial charge transfer in the polymer backbone and a low band-gap of 1.3 eV. Characterization of APFO-Green1 include measurement of light absorption and emission at extended wavelengths and high hole mobility was found. Blends of the polymer with different fullerene derivs. exhibit unusually high photovoltaic performance at long wavelengths, making this type of conjugated polymers promising for application in plastic solar cells.

Bostadshus utan traditionellt uppvärmningssytem - Resultat från två års mätningar
- 2004
-
Rapport (refereegranskat)abstract
- Twenty terrace houses without a traditional heating system has been built in Lindås, Sweden. The houses are extremely well insulated and very airtight. They are equipped with a high efficiency ventilation heat recovery system. Each house also has a 5 m2 solar collector that is designed to cover 50% of the energy supply for hot water use. The total electricity consumption and the air temperature have on an hourly base been monitored in two positions for each of the houses. Further has the environmental conditions, i.e. outdoor temperature, wind, sun etc been monitored. In six of the houses separate measurements of electricity consumption for ventilation and hot water has also been performed. In these six houses also the temperature and humidity in the bathrooms has been measured. One of the houses has been used for more extensive measurements. In this house the presence of inhabitants has been simulated by the use of electrically heated manikins. Humidity gain is achieved by remote controlled showering in the bathroom. During the summer of 2003 an automatic window airing system was also introduced. The results show that the mean value of the indoor air temperatures in most cases is equivalent to or higher than those expected in houses with a traditional heating system. The fluctuations are however sometimes a little bit larger. The total energy use is on an average much lower than for a traditional house with a heating system, but still higher than estimated when designing the houses. The heat from household electricity consumption is in most cases more than sufficient to keep the indoor climate within acceptable limits. However, some additional heat source is required for some periods during wintertime. For these houses most of the heat required can be supplied through a small reheater in the air-handling unit. In the actual case, the reheaters in the gable houses should have been larger and some additional heater in the upper bathroom would have increased the thermal comfort. The air-handling unit control system did initially not work properly. In spring, summer, autumn and sometimes even in the wintertime, window airing is necessary to keep the indoor air temperature down to a reasonable level. The automatic window airing system showed promising results. The conclusion is that it is possible to build well-insulated and very airtight houses without a traditional heating system in a Nordic climate.
