BARGAINING WITH COMMITMENT UNDER AN UNCERTAIN DEADLINE
2006
We consider an infinite horizon bargaining game in which a deadline can arise with positive probability and where players possess an endogenous commitment device. We show that for any truncation of the game, the equilibrium agreement can only take place if the deadline arises within this finite horizon. Since the deadline is an uncertain event, the equilibrium exhibits agreements which are delayed with positive probability.
The Marketisation of Higher Education: Antecedents, Processes, and Outcomes
2021
This chapter explores the ideological antecedents, processes, and outcomes of the marketisation of higher education, with an emphasis on business schools in particular. The chapter begins with a discussion of the theory of Scandinavian New Institutionalism in the context of higher education, explaining how ideologies spread across nations and fields through adoption and adaptation. It then elaborates the ideologies of neoliberalism and managerialism, and their relation to New Public Management. The chapter continues by elucidating the processes which are related to marketisation—namely commodification, corporatisation, and de-professionalisation. It then enumerates the various outcomes of t…
Threats and attitudes toward Russian-speaking immigrants: a comparative study between younger and older Finns
2014
Using integrated threat theory as a theoretical lens to detect negative attitudes toward minority groups, this study compares and contrasts the perceptions and attitudes of older and younger Finns toward Russian-speaking minorities in Finland. A sample of high school students between 16 and 20 years of age represented the younger generation, while individuals over 65 years of age represented the older generation. The total sample was 242. Results indicated that there is a positive correlation between threat perception and prejudice. Results revealed that both groups have prejudices against Russian speakers and that these prejudices are related to the perception of realistic threat and negat…
A cross-cultural analysis of organizational dissent and workplace freedom in five European economies.
2014
Individuals in five European countries—Finland, France, Germany, Spain, and the United Kingdom (n = 1184)—completed a survey exploring the relationship between organizational dissent and workplace freedom of speech. Results revealed workplace freedom of speech is positively correlated with dissent among the entire sample in France and in Germany. Results in Spain were nonsignificant. In the United Kingdom, there was a negative relationship between workplace freedom of speech and dissent. There was a negative relationship between workplace freedom of speech and articulated dissent and a positive relationship with latent dissent in Finland. Moreover, MANCOVA testing showed nationality to have…
Mate choice for indirect genetic benefits: scrutiny of the current paradigm
2007
Summary 1Sexual selection through mate choice, and in particular female choice for indirect fitness benefits for their offspring, is a major paradigm that currently seems to enjoy almost unequivocal acceptance. A large body of theoretical work has been built to explain the evolution of mate choice in the absence of direct benefits, and the empiricists have enthusiastically verified the various assumptions and predictions of the theory. 2However, the relative importance of mate choice for indirect benefits in comparison to choice for direct benefits or to other mechanisms of sexual selection such as male–male competition or sensory exploitation remains a controversial issue, and this seems t…
Approximated overlap error for the evaluation of feature descriptors on 3D scenes
2013
This paper presents a new framework to evaluate feature descriptors on 3D datasets. The proposed method employs the approximated overlap error in order to conform with the reference planar evaluation case of the Oxford dataset based on the overlap error. The method takes into account not only the keypoint centre but also the feature shape and it does not require complex data setups, depth maps or an accurate camera calibration. Only a ground-truth fundamental matrix should be computed, so that the dataset can be freely extended by adding further images. The proposed approach is robust to false positives occurring in the evaluation process, which do not introduce any relevant changes in the …
Stability and -gain controller design for positive switched systems with mixed time-varying delays
2013
This paper investigates the problems of stability and L"1-gain controller design for positive switched systems with mixed time-varying delays. The mixed time-varying delays are presented in the forms of discrete delay and distributed delay. The purpose of this paper is to design a class of switching signals and a state feedback controller for the considered system such that the resulting closed-loop system is exponentially stable with L"1-gain performance. By constructing an appropriate co-positive type Lyapunov-Krasovskii functional and using the average dwell time approach, we propose a sufficient condition to ensure the exponential stability with weighted L"1-gain performance for the sys…
Machine Learning Techniques for Intrusion Detection: A Comparative Analysis
2016
International audience; With the growth of internet world has transformed into a global market with all monetary and business exercises being carried online. Being the most imperative resource of the developing scene, it is the vulnerable object and hence needs to be secured from the users with dangerous personality set. Since the Internet does not have focal surveillance component, assailants once in a while, utilizing varied and advancing hacking topologies discover a path to bypass framework " s security and one such collection of assaults is Intrusion. An intrusion is a movement of breaking into the framework by compromising the security arrangements of the framework set up. The techniq…
Reducing False Node Failure Predictions in HPC
2019
Future HPC applications must be able to scale to thousands of compute nodes, while running for several days. The increased runtime and node count inconveniently raises the probability of hardware failures that may interrupt computations. Scientists must therefore protect their simulations against hardware failures. This is typically done using frequent checkpoint& restart, which may have significant overheads. Consequently, the frequency in which checkpoints are taken should be minimized. Predicting hardware failures ahead of time is a promising approach to address this problem, but has remaining issues like false alarms at large scales. In this paper, we introduce the probability of unnece…
Positive mood induction and well being
2009
The aim of this study is to test the role of consecutive positive mood induction virtual procedures on satisfaction of life of people with subclinical levels of sadness and/or anxiety. This is a work in progress and positive effects of mood induction on satisfaction and well being are expected.
