However, the persistence of unfavorable food preferences is a significant obstacle to changing eating behavior. Here we explored the effects of posthypnotic suggestions (PHS) on food-related decisions by measuring food choices, subjective ratings, and indifference points. In Session 1, demographic data and hypnotic susceptibility of participants were assessed. In Session 2, following hypnosis induction, PHS aiming to increase the desirability of healthy food was delivered. Afterward, a task set was administrated twice, once when PHS was activated and once deactivated. The order of PHS activation was counterbalanced across participants. The task set included a liking-rating task for 170 pictures of different food items, followed by an online supermarket where participants were instructed to select enough food for a fictitious week of quarantining from the same item pool. After 1 week, Session 3 repeated Session 2 without hypnosis induction in order to assess the persistence of PHS. The crucial dependent measures were food choices, subjective ratings, and the indifference points as a function of time and PHS condition.}, language = {en} } @misc{HoelzleBoerBjoerk2020, author = {H{\"o}lzle, Katharina and Boer, Harry and Bj{\"o}rk, Jennie}, title = {Crisis management through creativity and innovation}, series = {Creativity and innovation management}, volume = {29}, journal = {Creativity and innovation management}, number = {2}, publisher = {Wiley-Blackwell}, address = {Oxford [u.a.]}, issn = {0963-1690}, doi = {10.1111/caim.12385}, pages = {195 -- 197}, year = {2020}, language = {en} } @article{BenlianWienerCrametal.2022, author = {Benlian, Alexander and Wiener, Martin and Cram, W.

We attempt to evaluate the efficacy of such policies in the context of the Gaza Strip, where Israel's blockade and military interventions, purportedly intended to erode support for Hamas, have inflicted hardship on the civilian population. We combine Palestinian public opinion data, Palestinian labor force surveys, and Palestinian fatalities data, to understand the relationship between exposure to Israeli policies and Palestinian support for militant factions. Our baseline strategy is a difference-in-differences specification that compares the gap in public opinion between the Gaza Strip and the West Bank during periods of intense punishment with the gap during periods when punishment is eased. Consistent with previous research, we find that Palestinian fatalities are associated with Palestinian support for more militant political factions. The effect is short-lived, however, dissipating after merely one quarter. Moreover, the blockade of Gaza itself appears to be only weakly associated with support for militant factions. Overall, we find little evidence to suggest that Israeli security policies toward the Gaza Strip have any substantial lasting effect on Gazan support for militant factions, neither deterring nor provoking them relative to their West Bank counterparts. Our findings therefore call into question the logic of Israel's continued security policies toward Gaza, while prompting a wider re-examination of the efficacy of deterrence strategies in other asymmetric conflicts.}, language = {en} } @article{AbramovaWagnerOltetal.2022, author = {Abramova, Olga and Wagner, Amina and Olt, Christian M. and Buxmann, Peter}, title = {One for all, all for one}, series = {International Journal of Information Management}, volume = {64}, journal = {International Journal of Information Management}, publisher = {Elsevier}, address = {Kidlington}, issn = {0268-4012}, doi = {10.1016/j.ijinfomgt.2022.102473}, pages = {1 -- 16}, year = {2022}, abstract = {We propose a conceptual model of acceptance of contact tracing apps based on the privacy calculus perspective.

Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment.

Under rational expectations, we show that a time-consistent policy outcome exists with either a zero carbon tax or a prohibitive carbon tax that leads to zero fossil investments - an "all-or-nothing" policy. Although stranded assets are crucial to such a bipolar outcome, they disappear again under time-consistent policy.

Our unique setup exploits data from a large-scale lab-in-the-field experiment in a quasi-experimental evaluation framework. We find that the policy caused male, but not female, immigrants to significantly increase their cooperativeness toward natives. We show that the increase in out-group cooperation among immigrant boys is an outcome of more trust rather than a reflection of stronger other-regarding preferences towards natives. In exploring factors that may explain these behavioral effects, we present evidence that the policy also led to a near-closure of the educational achievement gap between young immigrant men and their native peers.

In this contribution we follow the recent call made by Moloney and Rosenbloom in this journal to make use of "public administrative theory and empirically based knowledge in analyzing the behavior of international and regional organizations" and offer a systematic analysis of the inner structures of these administrative bodies. Changes in these structures can reflect both the (re-)assignment of responsibilities, competencies, and expertise, but also the (re)allocation of resources, staff, and corresponding signalling of priorities. Based on organizational charts, we study structural changes within 46 international bureaucracies in the UN system. Tracing formal changes to all internal units over two decades, this contribution provides the first longitudinal assessment of structural change at the international level. We demonstrate that the inner structures of international bureaucracies in the UN system became more fragmented over time but also experienced considerable volatility with periods of structural growth and retrenchment. The analysis also suggests that IO's political features yield stronger explanatory power for explaining these structural changes than bureaucratic determinants. We conclude that the politics of structural change in international bureaucracies is a missing piece in the current debate on international public administrations that complements existing research perspectives by reiterating the importance of the political context of international bureaucracies as actors in global governance.}, language = {en} } @article{BaeumlMarcusSiedler2023, author = {B{\"a}uml, Matthias and Marcus, Jan and Siedler, Thomas}, title = {Health effects of a ban on late-night alcohol sales}, series = {Health economics}, volume = {32}, journal = {Health economics}, number = {1}, publisher = {Wiley}, address = {New York, NY}, issn = {1099-1050}, doi = {10.1002/hec.4610}, pages = {65 -- 89}, year = {2023}, abstract = {This paper studies the impact of a ban on late-night off-premise alcohol sales between 10 p.m. and 5 a.m. in Germany.
