Revisiting Rittel and Webber's Dilemmas: Designerly Thinking Against the Background of New Societal Distrust
No full textIn this article, we posit designerly thinking as a family of design approaches that some believe are able to effectively respond to wicked problems. We will scrutinize this premise by revisiting Horst Rittel and Melvin Webber's 1973 article in which the notion of wicked problems was originally introduced. In it, Rittel and Webber note the emergence of a general sense of distrust in professionals in the 1960s and interpret it as a loss of confidence in the then leading approach to addressing societal problems: systems-based planning. Rittel and Webber formulated three dilemmas that societal problems pose, of which the second is their wickedness, and argued that planning does not resolve these dilemmas. In the 2010s, an emerging distrust in professionals has arisen once more, raising the question of whether designerly thinking is equipped to address societal issues. Our review and discussion of Rittel and Webber's three dilemmas reveals that designerly thinking currently does not resolve any of them, as there can always be groups that will oppose certain solutions. We argue that designerly thinking cannot overcome societal pluralism, but that designers can and should interpret social distrust as an invitation to discuss the consequences and their societal equity.Ethics & Philosophy of Technolog
Interview of author Walter Satterthwait
No full textWalter Satterthwait, author of a series of contemporary crime novels, talks about his protagonists Joshua Croft and Rita Mondragon, and his novels set in Santa Fe, New Mexico. Satterthwait describes how he came to writing crime stories and why he chose to use a Latina as a main character. He describes his exposure to different cultures, his childhood of frequent moves, how he came to writing, and how he developed his characters. Satterthwait is interviewed by Diana Rivera at the 2005 Left Coast Crime Conference held in El Paso, Texas
The Wickedness of Rittel and Webber’s Dilemmas
No full textRittel and Webber connected their notion of “wicked problems” to three fundamental planning dilemmas. Many approaches within public administration theory have explicitly addressed wicked problems yet hardly paid attention to the dilemmas. We revisit the planning dilemmas to find out their potential relevance for current administration theory and practice. We argue that the dilemmas evolve out of the current institutional setup, meaning that wicked problems cannot be resolved by better administrative frameworks or methods. Rather societal matters are to be included in decision-making, for instance, by seeing societal opposition as opportunities to learn to deal with the planning dilemmas.Ethics & Philosophy of Technolog

Magnetic resonance imaging of organ iron before and after correction of iron deficiency in patients with heart failure
No full textAims
Intravenous iron therapy (IVIT) is known to improve functional status in chronic heart failure (CHF) patients. The exact mechanism is not completely understood. We correlated magnetic resonance imaging (MRI) patterns of T2* iron signal in various organs to systemic iron and exercise capacity (EC) in CHF before and after IVIT.
Methods and results
We prospectively analysed 24 patients with systolic CHF for T2* MRI pattern of the left ventricle (LV), small and large intestines, spleen, liver, skeletal muscle, and brain for iron. In 12 patients with iron deficiency (ID), we restored iron deficit by IVIT using ferric carboxymaltose. The effects after 3 months were analysed by spiroergometry and MRI. Patients with vs. without ID showed lower blood ferritin, haemoglobin (76 ± 63 vs. 196 ± 82 μg/L and 12.3 ± 1.1 vs. 14.2 ± 1.1 g/dL, all P < 0.002), and in trend a lower transferrin saturation (TSAT) (19.1 [13.1; 28.2] vs. 25.1 [21.3; 29.1] %, P = 0.05). Spleen and liver iron was lower as expressed by higher T2* value (71.8 [66.4; 93.1] vs. 36.9 [32.9; 51.7] ms, P < 0.002 and 33.5 ± 5.9 vs. 28.8 ± 3.9 ms, and P < 0.03). There was a strong trend for a lower cardiac septal iron content in ID (40.6 [33.0; 57.3] vs. 33.7 [31.3; 40.2] ms, P = 0.07). After IVIT, ferritin, TSAT, and haemoglobin increased (54 [30; 104] vs. 235 [185; 339] μg/L, 19.1 [13.1; 28.2] vs. 25.0 [21.0; 33.7] %, 12.3 ± 1.1 vs. 13.3 ± 1.3 g/L, all P < 0.04). Peak VO2 improved (18.2 ± 4.2 vs. 20.9 ± 3.8 mL/min/kg−1, P = 0.05). Higher peak VO2 at anaerobic threshold was associated with higher blood ferritin, reflecting higher metabolic exercise capacity after therapy (r = 0.9, P = 0.0009). Increase in EC was associated with haemoglobin increase (r = 0.7, P = 0.034). LV iron increased by 25.4% (48.5 [36.2; 64.8] vs. 36.2 [32.9; 41.9] ms, P < 0.04). Spleen and liver iron increased by 46.4 and 18.2%, respectively (71.8 [66.4; 93.1] vs. 38.5 [22.4; 76.9] ms, P < 0.04 and 33.5 ± 5.9 vs. 27.4 ± 8.6 ms, P < 0.007). Iron in skeletal muscle, brain, intestine, and bone marrow remained unchanged (29.6 [28.6; 31.2] vs. 30.4 [29.7; 30.7] ms, P = 0.7, 81.0 ± 6.3 vs. 82.9 ± 9.9 ms, P = 0.6, 34.3 ± 21.4 vs. 25.3 ± 14.1 ms, P = 0.2, 9.4 [7.5; 21.8] vs. 10.3 [6.7; 15.7] ms, P = 0.5 and 9.8 ± 1.5 vs. 13.7 ± 8.9 ms, P = 0.1).
Conclusions
CHF patients with ID showed lower spleen, liver, and in trend lower cardiac septal iron. After IVIT, iron signal of the left ventricle as well as spleen and liver increased. Improvement in EC was associated with increase in haemoglobin after IVIT. In ID, liver, spleen, and brain but not heart iron were associated with markers of systemic ID.Oskar‐Helene‐Heim Stiftung http://dx.doi.org/10.13039/501100008334Open-Access-Publikationsfonds 202
