We use data from a popular German Question & Answer community where goals are represented in the form of badges. In particular, our analysis of this data hinges on the fact, that in this Question & Answer community, badges in a hierarchical badge system are in-creasingly challenging to attain up to a certain badge. After this certain badge, the difficulty level sud-denly drops and remains constant throughout up to the last badge in the hierarchy. Our findings indi-cate that after successful badge achievement users increase their subsequent effort to attain the next badge, but only as long as badges represent a challenge to the user.

In this paper, we propose a more restrictive class of parallelizable parameterized problems called fixed-parameter parallel-tractable (FPPT). For a problem to be in FPPT, it should possess an efficient parallel algorithm not only from a theoretical standpoint but in practice as well. The primary distinction between FPPT and FPP is the parallel processor utilization, which is bounded by a polynomial function in the case of FPPT. We initiate the study of FPPT with the well-known k-vertex cover problem. In particular, we present a parallel algorithm that outperforms the best known parallel algorithm for this problem: using O(m) instead of O(n2) parallel processors, the running time improves from 4logn+O(kk) to O(k⋅log3n), where m is the number of edges, n is the number of vertices of the input graph, and k is an upper bound of the size of the sought vertex cover. We also note that a few P-complete problems fall into FPPT including the monotone circuit value problem (MCV) when the underlying graphs are bounded by a constant Euler genus.","lang":"eng"}],"publication":"Proceedings of the 10th International Conference on Combinatorial Optimization and Applications (COCOA)","type":"conference","file_date_updated":"2018-11-02T14:15:18Z","language":[{"iso":"eng"}],"ddc":["000"],"department":[{"_id":"63"}],"series_title":"LNCS","user_id":"477","_id":"177","project":[{"_id":"1","name":"SFB 901"},{"_id":"5","name":"SFB 901 - Subprojekt A1"},{"name":"SFB 901 - Project Area A","_id":"2"}],"page":"477-488","citation":{"ama":"Abu-Khzam FN, Li S, Markarian C, Meyer auf der Heide F, Podlipyan P.

(1999) propose a prospect theory model for goal behavior. Their analytical model is based on the assumption that goals inherit the main properties of the prospect theory value function, i.e., reference point dependence, loss aversion, and diminishing sensitivity. We investigate whether these main properties transfer to goal behavior in the field. We take user activity data from a gamified Question & Answer community and analyze how users adjust their contribution behavior in the days surrounding goal achievement, where goals are represented by badges. We find that users gradually increase their performance in the days prior to earning a badge, with performance peaking on the day of the promotion. In subsequent days, user performance gradually diminishes again, with the decline being strongest on the day immediately following the badge achievement. These findings reflect the characteristic S-shape of the prospect theory value function which is convex below the reference point and concave above it. Employing the target-based approach, we can interpret the value function as a cumulative density function of a unimodal probability distribution. Our results suggest that it is more likely that active members of the community focus on the next badge relative to the status already achieved, as their next goal and are less likely to focus on more remote (higher-ranked) badges. Our results thus support the transferability of the main properties of the prospect theory value function to goal behavior in the field and suggest a distinct shape of the value function around goals."}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":383896,"file_name":"deca.2016.0331.pdf","file_id":"5320","access_level":"closed","date_updated":"2018-11-02T16:01:08Z","creator":"ups","date_created":"2018-11-02T16:01:08Z"}],"publisher":"INFORMS","date_created":"2017-10-17T12:41:29Z","title":"Goals as Reference Points: Empirical Evidence from a Virtual Reward System","issue":"2","year":"2016","_id":"193","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A4","_id":"8"},{"name":"SFB 901 - Project Area A","_id":"2"}],"department":[{"_id":"276"}],"user_id":"16205","file_date_updated":"2018-11-02T16:01:08Z","type":"journal_article","status":"public","date_updated":"2022-01-06T06:54:02Z","author":[{"last_name":"von Rechenberg","full_name":"von Rechenberg, Tobias","first_name":"Tobias"},{"first_name":"Dominik","last_name":"Gutt","full_name":"Gutt, Dominik","id":"14368"},{"first_name":"Dennis","full_name":"Kundisch, Dennis","id":"21117","last_name":"Kundisch"}],"doi":"10.1287/deca.2016.0331","has_accepted_license":"1","publication_status":"published","page":"153--171","citation":{"ama":"von Rechenberg T, Gutt D, Kundisch D.

Typically, as providers of composed services, intermediaries interact on the sales side with users and on the procurement side with providers of single services. Thus, in how far a user request can be met often crucially depends on the prices and qualities of the different single services used in the composition. We study an intermediary who purchases two complementary single services and combines them. The prices paid to the service providers are determined by simultaneous multilateral Nash bargaining between the intermediary and the respective service provider. By using a function with constant elasticity of substitution (CES) to determine the quality of the composed service, we allow for complementary as well as substitutable degrees of the providers' service qualities. We investigate quality investments of service providers and the corresponding evolution of the single service quality within a differential game framework.

This study empirically investigates the relationship between quality and price, commonly captured by the Value dimension in multidimensional rating systems, to reveal whether reviewers form a perception of quality that they then express in the Value dimension, rather than in the Overall rating. We test our hypotheses on a comprehensive panel dataset for 14,859 Airbnb listings in New York. Our preliminary empirical findings show that an increase in price leads to a significant and substantial decrease in the Value rating, suggesting that Value ratings can offer a valuable source of information for potential buyers in addition to the supposedly inflated Overall rating. Moreover, this mechanism has substantial implications for potential buyers who seek to evaluate a listing’s quality and for a seller’s price setting.
