    Circuit limits the turn-on current transient to a specified amplitude and provides a low-impedance path between supply voltage and load after a prescribed time interval. The circuit offers a wide range of flexibility in adjusting peak current and automatic control of the initial peak current

    Synchronous Leisure, Jointness and Household Labor Supply

    This paper examines the synchronous leisure of spouses and the extent to which spouses spend time together. The time budget data set used in this paper allows for a distinction between simultaneous time-use of spouses and the actual time that spouses meet. A comparison between couples and matched singles suggests that only about 12 percent (45 minutes per day) of the synchronous leisure is caused by active synchronization. Spouses’ decisions about market work and leisure timing are very interdependent during most hours of the day. The results also suggest that, conditional on synchronous leisure, parents with high incomes spend more time together than others, while more educated people allocating less time to their spouses.Time-use; synchronous leisure; working hours; togetherness; family economics; statistical matching

    Antalet individer med funktionsnedsĂ€ttning ökar, dels beroende pĂ„ att numera kan sjukdomar botas som tidigare inte kunde botas och dels beroende pĂ„ att allt fler för tidigt födda barn kan rĂ€ddas. Den orala hĂ€lsan Ă€r ofta negativt pĂ„verkad hos personer med funktionsnedsĂ€ttning och det föreligger risk att dessa personer, trots ett större tandvĂ„rdsbehov Ă€n andra, erhĂ„ller mindre tandvĂ„rd. Anledningen till detta Ă€r inte helt kĂ€nd. Syftet med vĂ„ra studier var dĂ€rför att fördjupa kunskapen om hur personer med funktionsnedsĂ€ttning och deras anhöriga prioriterar och tĂ€nker om oral hĂ€lsa. Syftet med studierna var ocksĂ„ att fördjupa kunskapen om hur hĂ€lso- och sjukvĂ„rdspersonal samt tandvĂ„rdspersonal tĂ€nker om behov avseende bemötande och oral hĂ€lsa hos personer med funktionsnedsĂ€ttning. Den kvalitativa forskningsmetoden grounded theory har valts dĂ„ den Ă€r speciellt lĂ€mplig pĂ„ omrĂ„den dĂ€r teorier Ă€r sparsamt förekommande eller saknas. Öppna kvalitativa intervjuer har genomförts med 65 informanter. Studierna visade att förĂ€ldrar till barn med funktionsnedsĂ€ttning samt vuxna personer med kognitiva och/eller fysiska funktionsnedsĂ€ttningar inte prioriterade den orala hĂ€lsan pĂ„ grund av att andra mer akuta problem upplevdes som viktigare. MĂ„nga personer med funktionsnedsĂ€ttning vĂ„rdas kortare eller lĂ€ngre tid pĂ„ vĂ„rdinrĂ€ttningar, men kunskapen om oral hĂ€lsa var lĂ„g och inte prioriterad av personal inom hĂ€lso- och sjukvĂ„rden. Personer med funktionsnedsĂ€ttning Ă„terfinns inom sĂ„vĂ€l allmĂ€ntandvĂ„rd som specialisttandvĂ„rd och kunskapen om dessa patienters vĂ„rdbehov och bemötande av dem varierade mycket mellan olika kliniker, allmĂ€n- och specialisttandvĂ„rd och mellan olika tandvĂ„rdspersonal. Sammantaget utgör dessa resultat en möjlig förklaring till varför personer med funktionsnedsĂ€ttning löper ökad risk för oral ohĂ€lsa. Detta innebĂ€r ocksĂ„ att en prioriterad, god oral hĂ€lsa och ett adekvat bemötande av personer med funktionsnedsĂ€ttningar snarare kan handla om tur Ă€n om en jĂ€mlik rĂ€ttighet

    Private Alternatives and Early Retirement Programs

    This paper describes early retirement option programs in collective agreements in Sweden during the 1990s. We highlight the differences between actual pension benefits and those stipulated in the standard agreements. We find that the individuals frequently face far better options than those given by standard agreements. The mix and the timing of pensions is usually done in a non-trivial way. Thus, if we just relied on the standard agreement text, one important implication of these findings is that the effects of economic incentives on retirement very well might be over-estimated.Retirement; early retirement programs; occupational pension

    Two-impurity Kondo problem for correlated electrons

    Full text link
    The behavior of two magnetic impurities coupled to correlated electrons in one dimension is studied using the DMRG technique for several fillings. On-site Coulomb interactions among the electrons lead to a small Kondo screening cloud and an overall suppression of magnetic order. For arbitrary electronic correlations and large inter-impurity distances R, we find a 1/R^2 decay of magnetic correlations.Comment: RevTeX (version 3.0), 4 twocolumn pages with 6 embedded figures.
