    <description>Title: Immigration and election outcomes: Evidence from city districts in Hamburg
&lt;br/&gt;
&lt;br/&gt;Authors: Otto, Alkis Henri; Steinhardt, Max Friedrich
&lt;br/&gt;
&lt;br/&gt;Abstract: This paper provides new evidence on the effect of immigration on election outcomes. Our analysis makes use of data on city districts in Hamburg, Germany, during a period of substantial inflows of immigrants and asylum seekers. We find significant and robust effects for changes in foreigner shares on the electoral success of parties that built up a distinctive reputation in immigration politics. In particular, our fixed-effects estimates indicate a positive effect for xenophobic, extreme right-wing parties and an adverse effect for the Green party that actively campaigned for liberal immigration policies and minority rights. Overall, our results support the hypothesis that changes in local compositional amenities shape individual attitudes towards immigration.</description>

    <description>Title: Project scheduling with resource capacities and requests varying with time
&lt;br/&gt;
&lt;br/&gt;Authors: Hartmann, Sönke
&lt;br/&gt;
&lt;br/&gt;Abstract: This paper discusses an extension of the classical resource-constrained project scheduling problem (RCPSP) in which the resource availability as well as the resource request of the activities may change from period to period. While the applicability of this extension should be obvious, we provide a case study in order to emphasize the need for the extension. A realworld medical research project is presented which has a structure that is typical for many other medical and pharmacological research projects that consist of experiments. Subsequently, we provide a mathematical model and analyze some properties of the extended problem setting. We also discuss how priority rule based heuristics for the RCPSP can be applied to the extended problem. In addition to the priority rules themeselves, we outline a framework for randomized priority rule methods. In order to provide a basis for experiments, we propose an adaptation of standard RCPSP test instances to the extended version of the problem. Finally we report the computational results of the priority rule methods.</description>

    <description>Title: A survey of variants and extensions of the resource-constrained project scheduling problem
&lt;br/&gt;
&lt;br/&gt;Authors: Hartmann, Sönke; Briskorn, Dirk
&lt;br/&gt;
&lt;br/&gt;Abstract: The resource-constrained project scheduling problem (RCPSP) consists of activities that must be scheduled subject to precedence and resource constraints such that the makespan is minimized. It has become a well-known standard problem in the context of project scheduling which has attracted numerous researchers who developed both exact and heuristic scheduling procedures. However, it is a rather basic model with assumptions that are too restrictive for many practical applications. Consequently, various extensions of the basic RCPSP have been developed. This paper gives an overview over these extensions. The extensions are classified according to the structure of the RCPSP. We summarize generalizations of the activity concept, of the precedence relations and of the resource constraints. Alternative objectives and approaches for scheduling multiple projects are discussed as well. In addition to popular variants and extensions such as multiple modes, minimal and maximal time lags, and net present value-based objectives, the paper also provides a survey of many less known concepts.</description>
