Innovative governance from public policy unities
2016
Abstract This study examines which configurations explain the public policy for innovative governance through comparative qualitative analysis (QCA). The research analyzes the sub-system conditions through a case of Vietnam. The results show the minimum configurations of key variable conditions to achieve the outcome.
The effect of high performance work systems on small and medium size enterprises
2015
Abstract This study analyzes the processes that explain high performance work system (HPWS) effect on company performance in small and medium size enterprises (SMEs). This study tests this relationship in SMEs by selecting three high performance work practices (HPWP) and an outcome variable based on the return on investment. A regression model with a sample of 78 companies tests the hypothesis. Results confirm the positive effect of HPWP on the performance of SMEs.
Using high-potential firms as the key to achieving territorial development
2016
Abstract This study examines which entrepreneurial antecedents like education, gender, motivation, and age; and environmental variables like citizen insecurity enable high-potential firms to establish themselves and act as the key to territorial development. The inclusion of the variable citizen insecurity is unusual, but several authors note how a violent context can affect entrepreneurial activity in Latin America. Insecurity generates massive expenses for entrepreneurs, who must invest to protect themselves against violence and cover the extraordinary expenses arising from this violence. The data analysis technique is fuzzy-set qualitative comparative analysis (fsQCA), a powerful techniq…
Identifying patterns in channel usage across the search, purchase and post-sales stages of shopping
2015
Different motivations explain channel choice for search, purchase and post-sales.Channel choice is affected by the product category: search/purchase goods.Product involvement is the most relevant variable explaining multichannel behavior.Cross-channel synergies as consumers use both channels at each shopping stage.Meaningful segments based on the choice of channel are identified and characterized. Consumers today are using various channels to complete their purchase process. As shoppers pursue different goals at each stage of the process, channel choice may be explained by different drivers for search, purchase and post-sales activities. Our research framework is based on an extension of th…
Development of Customer-Orientation, Brand-Orientation and Business Performance within the First Ten Years of the Firm
2017
The business performance of young firms is significantly influenced by customer- and brand-oriented capabilities. These capabilities can be sustained competitive advantages for firms from an early age on and managers need to consciously develop them over time. In the first years, the development of these firms is still highly dependent on their environment. The products and services are still under development, and there are only little resources and market information available. Therefore, the development of customer-orientation, brand-orientation and their impact on business performance at this age is crucial to be understood for founders to appropriately manage these capabilities. The pu…
A family life cycle model adapted to the Spanish environment
2001
Aims to demonstrate, from a marketing and market segmentation point of view, the need to adapt the construct of the family life cycle to the particular features of the Spanish social environment, given the obvious differences in the structure of Spanish households in relation to the USA. From this marketing and cross‐cultural approach, a review of the literature has been conducted on the evolution of the construct and the most significant models that have been arising as the outcome of that evolution. A new life cycle model has been designed reflecting these particular features. Also, on the basis of data taken from the Family Budgets Survey, the capacity of the adapted model has been analy…
Bayesian methods in cost-effectiveness studies: objectivity, computation and other relevant aspects.
2009
In a probabilistic sensitivity analysis (PSA) of a cost-effectiveness (CE) study, the unknown parameters are considered as random variables. A crucial question is what probabilistic distribution is suitable for synthesizing the available information (mainly data from clinical trials) about these parameters. In this context, the important role of Bayesian methodology has been recognized, where the parameters are of a random nature. We explore, in the context of CE analyses, how formal objective Bayesian methods can be implemented. We fully illustrate the methodology using two CE problems that frequently appear in the CE literature. The results are compared with those obtained with other popu…
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 …
An appraisal of Piero Sraffa's 'The Laws of Returns under Competitive Conditions'
2001
The paper proposes a new interpretation of Sraffa's 1926 Economic Journal article, ‘The Laws of Returns under Competitive Conditions’, according to which the latter derives from the same strategy of research which underlies its 1925 Italian precursor, ‘Sulle relazioni fra costo e quantità prodotta’. Sraffa tested the explanatory power of a Marshallian monopolistic partial equilibrium model and concluded that that model is able to treat one source of variable returns (firm-internal economies); but this articulation of Marshall‘s theory does not substantially improve on the trade-off between logical consistency and empirical relevance which afflicted the theory in its whole. © 2001, Taylor & …
Sensitivity of Estimators for Measuring Information Amount in Web-Based Medical Documents
2018
Nowadays, communication between patient and doctor during an appointment has changed significantly owning to the opportunity that medical portals provide. Whether or not necessarily appreciated by the doctors, the patients became more aware of the first symptoms’ suggesting a particular disease and the medical procedures that apply as a standard. Estimating amount of reliable factual medical information in a document is carried out by parametrizing space of digital documents and dividing it into subsequent layers that represent distribution of the system responses computed as random variables to a query about medical information. Analyzed are the following attributes: dynamism of decrease o…
