Edible Wild Vegetables Urtica dioica L. and Aegopodium podagraria L.–Antioxidants Affected by Processing
No full textUrtica dioica L. and Aegopodium podagraria L., also known as stinging nettle and ground elder, are edible wild green vegetables rich in bioactive and antioxidant polyphenols, vitamins, and minerals. Antioxidant activity assays (TEAC-, DPPH-, and TPC-assay) in combination with HPLC measurements, to qualify and quantify their chemical compositions, were used. Firstly, the drying methods affected the antioxidant activity of further processing stages, and outcomes were dependent on the species. Secondly, cooking increased the antioxidant activity due to higher concentrations of bioactive compounds, and released bound compounds through the rupture of cell structures. Furthermore, fridge storage (3 days at 7 °C) resulted in the lowest antioxidant activity, compared to freezer storage (30 days at −20 °C). Added 5-caffeoylquinic acid (0.3 mM) led to an increased antioxidant activity, most noticeably in freeze-dried samples. Synergistic effects of 5-caffeoylquinic acid were primary found in freeze-dried samples, analyzed fresh or after storage in the fridge. Metal-chelates can lower the antioxidant activity in plant matrices. Edible wild green vegetables are rich in polyphenols and processing can even increase their concentrations to boost the potential health effects. In general, selected quantified phenolics are not solely responsible for the antioxidant activity; minerals, processing, and interactions in plant matrices also contribute decisively
How Does Dipping into Your Pension Affect Your Retirement Wealth?
No full textAlthough pensions, both public and private, are intended to provide income during retirement, a growing number of American workers receive part or all their employer-provided pensions in the form of a cash settlement, called a lump-sum distribution, when they change jobs. They have many choices of what to do with that money: for example, they can rool it over into an Individual Retirement Account (IRA), spend the money or pay or debt, transfer it to the pension plan of a new employer, or even leave the money with the old employer's pension plan. Policymakers are concerned that workers who spend their pension distributions on current consumption are depriving themselves of the financial resources they will need for retirement. This policy brief describes some results from an ongoing study on the long-term economic consequences of lump-sum pension distributions. The study uses detailed information on employment histories, pensions, and wealth from Wave 1 (1992) of the Health and Retirement Study (HRS), a nationally representative survey of individuals between the ages of 41 and 61.

Are language production problems apparent in adults who no longer meet diagnostic criteria for attention-deficit/hyperactivity disorder?
No full textIn this study, we examined sentence production in a sample of adults (N = 21) who had had attention-deficit/hyperactivity disorder (ADHD) as children, but as adults no longer met DSM-IV diagnostic criteria (APA, 2000). This “remitted” group was assessed on a sentence production task. On each trial, participants saw two objects and a verb. Their task was to construct a sentence using the objects as arguments of the verb. Results showed more ungrammatical and disfluent utterances with one particular type of verb (i.e., participle). In a second set of analyses, we compared the remitted group to both control participants and a “persistent” group, who had ADHD as children and as adults. Results showed that remitters were more likely to produce ungrammatical utterances and to make repair disfluencies compared to controls, and they patterned more similarly to ADHD participants. Conclusions focus on language output in remitted ADHD, and the role of executive functions in language production

H. Tristram Engelhardt Jr. interprete di Kant. A proposito di libertà e suicidio
No full textThis paper investigates the critical interpretation that Hugo Tristram Engelhardt Jr. gives of Kantian ethics: on the one hand Engelhardt relies on it and in particular on the principle of autonomy, on the other hand he criticizes the Kantian justification of freedom. From this different interpretation of freedom of will derives a different way of conceiving some fundamental concepts, including those of person and dignity (Würde). These concepts are now reinterpreted in a purely subjectivistic sense (i.e. according to an individualistic, not transcendental subjectivity), and therefore in an inevitably anti-Kantian sense. Similarly, Engelhardt's justification of suicide and assisted suicide stand in opposition to Kant's view
