  • Privacy-preserving publish/subscribe service in untrusted third-Party Platform
    2016 IEEE International Conference on Communications (ICC), 2016
    Co-Authors: Tracy Yingying Cheng, Jianfei He
    Abstract:

    Nowadays, many organizations or corporations, such as banks, hospitals, schools, etc., use third-Party Platform to send notifications or information to their customers or users. This communication model can be generalized to the publish/subscribe model. The publisher will send the content to the subscriber whenever there is any new content that matches the interest of the subscriber. However, the content may contain users' privacy which is sent in plain text by the third-Party Platform. When the Platform is not fully trusted, users' privacy is at the risk. In this paper we propose a secure protocol to protect users' privacy against the untrusted third-Party Platform. Our privacy preserving protocol has three main advantages: 1) There is no need to set up a secure synchronous communication channel between the subscriber and the publisher in our protocol. 2) There is no need to introduce any Certificate Authority (CA) for certifying publishers or subscribers in our protocol. 3) There is no need for subscribers or publishers to remember any additional key for each subscription or publication, which makes our protocol scalable to large pub/sub system.

  • Do leadership-dominated parties change more?
    Journal of Elections Public Opinion & Parties, 2017
    Co-Authors: Gijs Schumacher, Nathalie Giger
    Abstract:

    It is often assumed that political parties have more fluid Party Platforms than in the past because internal veto players – like Party activists – have lost the power to restrain the office-seeking Party elite. Several case studies subscribe to this view. However, there is no systematic assessment of this relationship. Using new data this research note investigates this relationship and finds a clear positive effect of leadership domination on Party Platform change. With leadership domination increasing over time, our model predicts increasing fluidity in Party Platforms. This note provides a motivational and a numerical argument in favor of this hypothesis, considers alternative hypotheses and provides empirical evidence for the claim using two different datasets.

  • Living in the Past or Living in the Future? Analyzing Parties’ Platform Change In Between Elections,The Netherlands 1997–2014
    Political Communication, 2017
    Co-Authors: Mariken A.c.g. Van Der Velden, Gijs Schumacher
    Abstract:

    Do parties change their Platform in anticipation of electoral losses? Or do parties respond to experienced losses at the previous election? These questions relate to two mechanisms to align public opinion with Party Platforms: (1) rational anticipation, and (2) electoral performance. While extant work empirically tested, and found support for, the latter mechanism, the effect of rational anticipation has not been put to an empirical test yet. We contribute to the literature on Party Platform change by theorizing and assessing how Party performance motivates parties to change their Platform in-between elections. We built a new and unique dataset of >20,000 press releases issued by 15 Dutch national political parties that were in parliament between 1997 and 2014. Utilizing automated text analysis (topic modeling) to measure parties’ Platform change, we show that electoral defeat motivates Party Platform change in-between elections. In line with existing findings, we demonstrate that parties are backward-loo...

  • how aspiration to office conditions the impact of government participation on Party Platform change
    American Journal of Political Science, 2015
    Co-Authors: Gijs Schumacher, Marcpaul Van De Wardt, Michael Baggesen Klitgaard
    Abstract:

    Considerable ambiguity exists regarding the effect of government/opposition status on Party Platform change. Existing theories predict that (1) it has no effect, (2) opposition parties change more, (3) opposition parties change more after several spells in opposition, and (4) parties’ responses vary because of different goal orientations. We propose that a Party's aspiration to office, measured by its historical success or failure in entering office, determines a Party's reaction to being in opposition or government. We hypothesize that, because of loss aversion, parties with low office aspiration change more when they are in government than when they are in opposition. Conversely, parties with high office aspiration change more as opposition Party than as government Party. We find evidence for these hypotheses through a pooled time-series cross-sectional analysis of 1,686 Platform changes in 21 democracies, using the Comparative Manifesto Data and an innovative measure of Party Platform change.
