Article history: Received 8 December 2013 Available online 16 February 2014 In times of rising longevity and shortage of skilled workers, post-retirement work has become increasingly prevalent in many countries. However, not much is known about the expectations and facilitating factors associated with work-related activities after retirement. In two studies we draw on the social cognitive caree...

In realistic applications, it is often desirable to integrate different ontologies into a single, reconciled ontology. Ideally, one would expect the individual ontologies to be developed as independently as possible, and the final reconciliation to be seamless and free from unexpected results. This allows for the modular design of large ontologies and facilitates knowledge reuse tasks. Few onto...

In a world where markets work perfectly, investment decisions should have very little to do with the income, wealth or social status of the decision maker. Whether or not a particular piece of investment should be undertaken ought to be determined by the returns it promises and the market price of capital, adjusted, if necessary, for the market price of the extra risk it entails. The logic is a...

It is of no doubt that social media sites have become the most dominated subject in today life. However, the effect of those websites has widely disseminated not only into social life but into the business world as well. Recruitment is one of the topics that have influence by social networking sites. Previous studies have shown growing use of social networking sites such as Facebook, Twitter an...

In this paper we study experimentally four remedies to overcome inefficiencies that arise from the incompleteness of contracts. These remedies are reciprocity, repeated game effects, social embeddedness, and incentive contracts. In our baseline treatment we find that reciprocity is a powerful contract enforcement device. A second experiment establishes that repeated game effects interact with r...

Influence maximization(IM) problem is to find a seed set in a social network which achieves the maximal influence spread. This problem plays an important role in viral marketing. Numerous models have been proposed to solve this problem. However, none of them considers the attributes of nodes. Paying all attention to the structure of network causes some trouble applying these models to real-word...

In a classic article reviewing the field of planned change, Chin and Benne (1984) outlined three meta-approaches to the implementation of change in social and organizational contexts. These meta-theories of change – Rational-Empirical, Normative-Reeducative, and Power-Coercive – summarized the field of then-existing knowledge related to innovation at a systems level. Chin and Benne’s resulting ...

We consider influence maximization (IM) in social networks, which is the problem of maximizing the number of users that become aware of a product by selecting a set of “seed” users to expose the product to. While prior work assumes a known model of information diffusion, we propose a parametrization in terms of pairwise reachability which makes our framework agnostic to the underlying diffusion...

We extend research on social evaluations and crisis management by explicating the sociocognitive mechanisms that influence how an organization and its external evaluators perceive and respond to the onset of a crisis. Specifically, we highlight the role of social approval—evaluators’ general affinity toward an organization—not only as a critical outcome of crisis management but also as an impor...
