Beyond path dependence: Explorative orientation, slack resources, and managerial intentionality to internationalize in SMEs
2015
Abstract Managerial intentionality plays an important role in a firm's selection of its internationalization path. In relation to small and medium sized enterprises (SMEs), most studies focus on the individual traits that foster managerial intentionality without considering organizational-level antecedents. This study seeks to address this gap by focusing on two organizational antecedents: the firm's exploration and exploitation orientations, and its slack resources. The firm's orientations affect the application of different learning processes, including knowledge acquisition, information interpretation, and knowledge diffusion, and they shape the subjective norms prevalent in the organiza…
Treating the crowd fairly: increasing the solvers’ self-selection in idea innovation contests
2020
Abstract The success of idea crowdsourcing contests depends on the wideness of the number of solvers that voluntarily self-select to solve the problem broadcast by the seeker and previous research has started to highlight the role of fairness in the self-selection process of solvers. This study aims at deepening the understanding concerning how fairness can influence the solvers’ self-selection. By applying a netnographic research design, we identify possible unexplored facets of fairness in the crowdsourcing context, i.e., prize award, award guaranteed, and non-blind contest. Theoretically, we drew from the organizational justice and fairness literature to develop hypotheses about how the …
Cross-cultural Differences in Movie Selection. Decision-making of German, U.S., and Singaporean Media Users for Video-on-Demand Movies
2017
ABSTRACTThis article investigates the process of individual decision-making for movies on video-on-demand platforms from a cross-cultural perspective. Models of decision-making and movie selection act as theoretical underpinning. The article focuses on the information search phase and examines media consumers' information use during movie selection. Empirically the article relies on an online survey among N = 694 German, the U.S., and Singaporean students. Results indicate that participants considered only a limited amount of information before carrying out their choice. Participants shared a preference for product-related cues over crowd-related cues signaling previous user-experiences. Wi…

Social representations as a diagnostic tool for identifying cultural and other group differences
2005
The aim of this research is to develop a procedure for data collection within a social representations perspective that may be of use in diverse contexts in which investigators wish to understand and compare the norms and values associated with a particular social object in different social or cultural groups. The social representation of sport is studied in two culturally distinct countries, Morocco and France, with the use of an innovative procedure derived from the Model of Basic Cognitive Schemes (Rouquette, 1990, 1994b). The results reveal a difference in the appropriation of values related to sport in the two countries: the social representation of sport for the Moroccans is focused a…
Accelerating Causal Inference and Feature Selection Methods through G-Test Computation Reuse
2021
This article presents a novel and remarkably efficient method of computing the statistical G-test made possible by exploiting a connection with the fundamental elements of information theory: by writing the G statistic as a sum of joint entropy terms, its computation is decomposed into easily reusable partial results with no change in the resulting value. This method greatly improves the efficiency of applications that perform a series of G-tests on permutations of the same features, such as feature selection and causal inference applications because this decomposition allows for an intensive reuse of these partial results. The efficiency of this method is demonstrated by implementing it as…
ℓ1-Penalized Methods in High-Dimensional Gaussian Markov Random Fields
2016
In the last 20 years, we have witnessed the dramatic development of new data acquisition technologies allowing to collect massive amount of data with relatively low cost. is new feature leads Donoho to define the twenty-first century as the century of data. A major characteristic of this modern data set is that the number of measured variables is larger than the sample size; the word high-dimensional data analysis is referred to the statistical methods developed to make inference with this new kind of data. This chapter is devoted to the study of some of the most recent ℓ1-penalized methods proposed in the literature to make sparse inference in a Gaussian Markov random field (GMRF) defined …
Selecting information to answer questions: Strategic individual differences when searching texts
2011
The purpose of the study was to explore students’ selection of information strategies in a task-oriented reading situation. 72 secondary school students read two texts and answered six questions per text, three of which were manipulated to induce a misleading matching between the wording of the question and distracting pieces of information in the text. The reading and question-answering were presented with the software Read&Answer. We analyzed how skilled and less-skilled comprehenders were attracted to the distracting pieces of information and how this affected reading patterns and task outcomes. Skilled comprehenders scored higher and were able to discard the distracting information. In …
The Gaia-ESO Survey: matching chemodynamical simulations to observations of the Milky Way
2017
The typical methodology for comparing simulated galaxies with observational surveys is usually to apply a spatial selection to the simulation to mimic the region of interest covered by a comparable observational survey sample. In this work, we compare this approach with a more sophisticated post-processing in which the observational uncertainties and selection effects (photometric, surface gravity and effective temperature) are taken into account. We compare a 'solar neighbourhood analogue' region in a model MilkyWay-like galaxy simulated with RAMSES-CH with fourth release Gaia-ESO survey data. We find that a simple spatial cut alone is insufficient and that the observational uncertainties …
Genetic compatibility and sexual selection
2005
In a recent review in TREE [1], Mays and Hill discuss the interface between sexual selection for good genes (i.e. female choice based on traits indicating heritable fitness) and sexual selection for genetic compatibility (i.e. how well the genes of the parents function together in their offspring). We feel that the scope of their contribution is somewhat limited, primarily because they implicitly equate genetic compatibility with genetic dissimilarity. Compatibility does, however, not equal dissimilarity.
