Farm and farmer capital foster adoption of improved quality agrochemical inputs in the cotton-wheat zone of the Punjab, Pakistan
(2019-12-23)
Adoption of yield-enhancing agricultural inputs fosters agricultural intensification in low-income countries. In Pakistan, initial adoption of agrochemicals is already widespread; the low quality of much of the inputs contributes to severe health, environmental and enduring pest problems, however.

On Measuring Some of the People Some of the Time with Some of the Items: The Search for Stability and Variation in Item Sets
(2019-02)
Psychological assessment is shaped by the items used and the persons assessed. Both items and persons typically represent a random or representative sample of a much larger item and person pool.

In this dissertation, I present the advantages of new state-of-the-art item and person sampling procedures in the context of personality development research (manuscript 1). ...

Mechanistic Insights into the intrinsic Kinase Regulation of LRRK2
(2019-06)
Obwohl Morbus Parkinson (PD) die zweithäufigste neurodegenerative Erkrankung darstellt, ist der Pathomechanismus kaum verstanden. Es ist jedoch erwiesen, dass PD assoziierte Mutationen die Aktivität der Leucine rich repeat kinase 2 (LRRK2) beeinflussen, sodass diese ein potentielles Drug Target darstellt. Für ein besseres Verständnis wurden daher der intrinsische regulatorische Mechanismus und der Einfluss von Mutationen auf LRRK2 untersucht. Zusätzlich wurde der Einfluss von Nanobodies gegen die ROC Domäne von LRRK2 ...
