  text: "Urged by the European Energy Crisis and the threatening consequences of severe\r\nnatural
    gas shortages, energy providers launched gas-saving initiatives incor-\r\nporating
    financial incentives to reduce residential natural gas consumption. In\r\ncollaboration
    with one of Germany’s largest energy providers, we conducted\r\na natural field
    experiment (N = 2,598) to evaluate the effectiveness of a\r\nbehaviorally-guided
    co-design of such a gas-saving initiative by implementing\r\ntwo established behavioral
    instruments – reminders of gas saving intentions and\r\ndescriptive norm feedback.
    Our findings show limited effectiveness of the behav-\r\nioral instruments during
    the high-price period. The feedback risks a “boomerang\r\neffect” among households
    with above-average initial savings, who reduce their\r\nconservation efforts in
    response. The reminder does not significantly enhance sav-\r\nings in our main
    specifications, yet, realizes 1 percentage point savings in alternate\r\nmodels
    refining for outliers. Potential mechanisms include a significant intention-\r\naction
    gap and misperceived effectiveness of energy-saving actions, which are not\r\nalleviated
    by the reminder."

  text: 'The study explores differences between three user types in the top tweets
    about the 2015 “refugee crisis” in Germany and presents the results of a quantitative
    content analysis. All tweets with the keyword “Flüchtlinge” posted for a monthlong
    period following September 13, 2015, the day Germany decided to implement border
    controls, were collected (N = 763,752). The top 2,495 tweets according to number
    of retweets were selected for analysis. Differences between news media, public
    and private actor tweets in topics, tweet characteristics such as tone and opinion
    expression, links, and specific sentiments toward refugees were analyzed. We found
    strong differences between the tweets. Public actor tweets were the main source
    of positive sentiment toward refugees and the main information source on refugee
    support. News media tweets mostly reflected traditional journalistic norms of
    impartiality and objectivity, whereas private actor tweets were more diverse in
    sentiments toward refugees. '

  text: 'Due to the Corona crisis, German Higher Education Institutions had to close
    their campuses in March and lecturers had to teach online. To understand how the
    Corona crisis affected students, first this article explains the structural and
    social inequalities in the German higher education system, using Tinto''s (1975;
    1997) student engagement theory. Second, the concept of Bergman-Rosamond et al.
    (2020) is used to analyze the challenges that Corona has raised for students,
    including current surveys. We found that the closure of the social space campus
    (and the Corona crisis as a whole) particularly hit hard those students who had
    previously been affected by (intersectional) inequality. Therefore, to lessen
    the specific challenges associated with the ad hoc transition to digital studying,
    the creation of a digital community of learning can help. We demonstrate how such
    a community can be created by the example seminar, "Digital practices: an autoethnographic
    observation". During the seminar, students recorded their digital technology use
    in a journal, and we analyzed the diary entries using the collaborate autoethnography
    method. The seminar example shows that this method is well suited for the development
    of a community of learning as it not only places students in the spotlight but
    as students work together on a topic they get to know each other, and a basis
    of trust is created through peer-feedback. Therefore, it was important to have
    a digital space (in this case Mahara) where the exchange could take place. The
    continuous insight into the students’ "learning status" enabled the lecturer to
    promote the learning and provide individual assistance for the students.'

  text: 'Employing four event dates of the U.S. “Troubled Asset Relief Program” (TARP)
    this paper empirically investigates the impact of the first announcement of TARP
    (September 19, 2008), the announcement of revised TARP (October 14, 2008), respective
    capital infusions under TARP-CPP and capital repayments on changes in shareholder
    value and risk exposure of 125 supported U.S. banks as perceived by the capital
    market through share price reactions for an entire sample period from September
    19, 2008 to June 16, 2010. Our analysis reveals a light and a dark side of TARP.
    While announcements as well as capital repayments may restore market confidence
    and financial stability, equity capital injections to banks are observed to be
    a severe impediment to an increase in bank shareholder value and financial soundness. '
