This essay takes a closer look at one of the most remarkable exemptions of the prevailing memory culture at Holocaust memorials： the sites and events highlighting Anne Frank and her short life in troubled times. Over the past years millions of travelers from all over the world have shown a genuine interest in learning about the life world of their young heroine thus creating what has been termed Anne Frank Tourism. In 2014, 1.2 million people visited the Anne Frank House in Amsterdam： the museum and educational center, the place in hiding where she wrote her now famous and widely read diary. Several other sites connected to the life path of Anne Frank, from her birth place in Frankfurt to the Bergen-Belsen Concentration Camp where her life prematurely ended, have also become part of the mostly young tourists＇ search for Anne Frank＇s life and legacy. With the rising popularity of Anne Frank related sites the management of some of the locales has become more problematic which is discussed in the context of a several museums, centers and historic sites. On a more general note, it is argued here that in recent years the more group oriented commemoration practices at Holocaust sites have given way to a trend of putting individual faces to the victims of the Holocaust. It was, in particular, novels, films and TV productions about the Holocaust that emphasized individual life paths and events and enticed visitation to more personalized sites. Steven Spielberg＇s popular movie Schindler＇s List, for example, contributed to ＂Schindler tourism＂, a form of special interest tourism in Krakow. More and more Holocaust memorial sites have also started to honor outstanding individuals or small groups in resistance and opposition to Nazi Germany. Examples of this are the fighters of the 1943 uprising at the Sobibor death camp and the courageous student members of the ＂White Rose＂ in Munich who stood up to the powers of the time and were executed. In the concluding part the question will be raised of what is the proper approach in the representation of the fate of the victims of Nazi Germany： A personalized approach or a greater focus on an explanation of the ideology and policies behind the rule of terror which may contribute to the visitors＇ better understanding of a complex history？展开更多

Both soil productivity and fertilizer applications affect crop yields. A long-term experiment with a winter wheat-summer maize rotation was established in 1989 in a field of the Fengqiu State Key Agro-Ecological Experimental Station, a region typical of the North China Plain, including seven treatments： 1） a balanced application of NPK chemical fertilizers （NPK）; 2） application of organic fertilizer （OM）; 3） application of 50% organic fertilizer and 50% NPK chemical fertilizers （1/2OMN）; 4） application of NP chemical fertilizers （NP）; 5） application of PK chemical fertilizer （PK）; 6） application of NK chemical fertilizers （NK）; and 7） unfertilized control （CK）. To investigate the effects of fertilization practices on soil productivity, further pot tests were conducted in 2007-2008 using soil samples from the different fertilization treatments of the long-term field experiment. The soil sample of each treatment of the long-term experiment was divided into three pots to grow wheat： with no fertilization （Potunf）, with balanced NPK fertilization （POtNPK）, and with the same fertilizer（s） of the long-term field experiment （Potori）. The fertilized soils of the field experiment used in all the pot tests showed a higher wheat grain yield and higher nutrient uptake levels than the unfertilized soil. Soil productivity of the treatments of the field experiment after 18 years of continuous fertilizer applications were ranked in the order of OM 〉 1/2OMN 〉 NPK 〉 NP 〉 PK 〉 NK 〉 CK. The contribution of soil productivity of the different treatments of the field experiment to the wheat grain yield of Potori was 36.0%-76.7%, with the PK and NK treatments being higher than the OM, 1/2OMN, NPK, and NP treatments since the soil in this area was deficient in N and P and rich in K. Wheat grain yields of PotNPK were higher than those of Potori and Potunf. The N, P, and K use efficiencies were higher in POtNPK than Potori and significantly positively correlated with wheat grain yield. Soil organic matter could be a better predictor of soil productivity because it correlated more strongly than other nutrients with the wheat grain yield of Potuf. Wheat yields of POtNPK showed a similar trend to those of Potunf, indicating that soil productivity improvement was essential for a further increase in crop yield. The long-term applications of both organic and chemical fertilizers were capable of increasing soil productivity on the North China Plain, but the former was more effective than the latter. The balanced application of NPK chemical fertilizers not only increased soil productivity, but also largely increased crop yields, especially in soils with lower productivity. Thus, such an approach should be a feasible practice for the sustainable use of agricultural soils on the North China Plain, particularly when taking into account crop yields, labor costs, and the limited availability of organic fertilizers.展开更多
