Human Motivation in Question: Discussing Emotions,Motives, and Subjectivity from a Cultural‐Historical Standpoint

Vygotsky, at the end of his life, advanced a new representation of a psychological system that was ruled by a cognitive‐emotional unity, a theorization that remains inconclusive due to Vygotsky's early death. This article discusses the advances made by Vygotsky in the comprehension of human motivation through his concepts of sense and perezhivanie at the end of his work. Through these concepts, he further advanced the discussion of motivation, despite the fact that these concepts have only very recently been considered a relevant part of his legacy in both Russian and Western psychology. This paper discusses the departure from and the historical presentations of the concept of motive in the following two main approaches of Soviet psychology that were mistakenly equated in Western interpretations: Vygotsky's approach, mainly at the first as last moment of his work, and Leontiev's Activity Theory. Based on the final theoretical positions of Vygotsky and of other Soviet authors, and further developing this legacy, this article proposes a new definition of motivation as a specific quality of subjectively configured systems and defines motive as intrinsic to the functioning of all psychological function defines subjective functions as subjectively configured processes. This new proposal of human motivation within a new way of defining subjectivity defines new categories as subjective senses and subjective configurations on which the author bases a specific approach for advancing the topic of subjectivity and motivation within a cultural‐historical framework.     

Linearity of regression for the past weak and ordinary records

In this paper we study the property of linearity of backward regression for non-adjacent records. In the case of weak records, a characterization of the geometric distribution is obtained. It also appears that a related characterization for ordinary records does not hold, showing the difference in conditional behaviour between weak and ordinary records.     

Campaign for education in democratic citizenship, Guadalajara, Mexico

Since the time of the Mexican Revolution that began in 1910(views on when it finished vary between 1917 and 1940) Mexicohad been ruled by the same, single political party, the PRI(the Partido Revolucionario Institucional, meaning the ‘InstitutionalRevolutionary Party’), until it finally lost a presidentialelection in 2000 to the right-wing Party of National Action,after seventy-one years in power. The PRI had stayed in powerthrough a mixture of ‘clientelism’, ‘populism’,‘corruption’ and the rigging of elections and helda tight control on the whole of Mexican society. In its effortsto bring about social change, from the 1990s onwards Mexicansociety began to concentrate its efforts on challenging thedominance held by the PRI at the national, federal level. Adebate on the ‘transition to democracy’ took offin both academic circles and social and civil organizationslooking for ways to create a new and different kind of relationshipbetween government and society. It was in that context that,as with many other civil organizations in Mexico, we in IMDEC¹considered how we might best open up more spaces for the cultureand practice of democracy and motivate citizens to activelycampaign on those issues impacting on their daily lives. Theissue, however, was how to engage this participation differently,in a more festive atmosphere, breaking with formal traditions,in such a way that people would feel better motivated to becomeinvolved in actively addressing the problems that surroundedthem. In this article, I want to share an experience, whichtook place between April and August 1994, before the local electionsof that year, based on a Campaign for Education in DemocraticCitizenship.     

Bayesian approach to the inverse problem in a light scattering application

In this article, static light scattering (SLS) measurements are processed to estimate the particle size distribution of particle systems incorporating prior information obtained from an alternative experimental technique: scanning electron microscopy (SEM). For this purpose we propose two Bayesian schemes (one parametric and another non-parametric) to solve the stated light scattering problem and take advantage of the obtained results to summarize some features of the Bayesian approach within the context of inverse problems. The features presented in this article include the improvement of the results when some useful prior information from an alternative experiment is considered instead of a non-informative prior as it occurs in a deterministic maximum likelihood estimation. This improvement will be shown in terms of accuracy and precision in the corresponding results and also in terms of minimizing the effect of multiple minima by including significant information in the optimization. Both Bayesian schemes are implemented using Markov Chain Monte Carlo methods. They have been developed on the basis of the Metropolis–Hastings (MH) algorithm using Matlab^® and are tested with the analysis of simulated and experimental examples of concentrated and semi-concentrated particles. In the simulated examples, SLS measurements were generated using a rigorous model, while the inversion stage was solved using an approximate model in both schemes and also using the rigorous model in the parametric scheme. Priors from SEM micrographs were also simulated and experimented, where the simulated ones were obtained using a Monte Carlo routine. In addition to the presentation of these features of the Bayesian approach, some other topics will be discussed, such as regularization and some implementation issues of the proposed schemes, among which we remark the selection of the parameters used in the MH algorithm.     

The Time Consistency of Optimal Monetary and Fiscal Policies

We show that optimal monetary and fiscal policies are time consistent for a class of economies often used in applied work, economies appealing because they are consistent with the growth facts. We establish our results in two steps. We first show that for this class of economies, the Friedman rule of setting nominal interest rates to zero is optimal under commitment. We then show that optimal policies are time consistent if the Friedman rule is optimal. For our benchmark economy in which the time consistency problem is most severe, the converse also holds: if optimal policies are time consistent, then the Friedman rule is optimal.     

Understanding the workweek of foreign born workers in the United States

I analyze the length of the workweek of foreign-born workers in the US I concentrate on workers supplying long hours of work—50 or more weekly hours and document that immigrants are less likely than natives to work long hours. Surprisingly, these differences are greatest among highly educated and salary paid workers, and persists even after conditioning for demographic characteristics. I explain these differences with two within occupation characteristics. First, relative to natives, immigrants are less likely to supply long work weeks if they work in occupations where the immigrant-native earnings differential is big. Second, immigrants are also less likely to supply long work weeks when they work in occupations with a wide dispersion of earnings. This second result is important, because the occupation dispersion of earnings has been used to characterize changes of the worker’s earnings over the worker life cycle (Bell and Freeman, Labour Economics: 8(2), 2001a; Working Time in Comparative Perspective, 2001b; Kuhn and Lozano, Journal of Labor Economics:26(2), 311–344, 2008), and a good measure of the incentives to supply long hours of work.

Bayesian analysis of the generalized gamma distribution using non-informative priors

The Generalized gamma (GG) distribution plays an important role in statistical analysis. For this distribution, we derive non-informative priors using formal rules, such as Jeffreys prior, maximal data information prior and reference priors. We have shown that these most popular formal rules with natural ordering of parameters, lead to priors with improper posteriors. This problem is overcome by considering a prior averaging approach discussed in Berger et al. [Overall objective priors. Bayesian Analysis. 2015;10(1):189–221]. The obtained hybrid Jeffreys-reference prior is invariant under one-to-one transformations and yields a proper posterior distribution. We obtained good frequentist properties of the proposed prior using a detailed simulation study. Finally, an analysis of the maximum annual discharge of the river Rhine at Lobith is presented.     

Initial resource heterogeneity differences between family and non-family firms: Implications for resource acquisition and resource generation

A fundamental, but overlooked stream of resource-based theory (RBT) is the analysis of combinations of initial heterogeneous resource endowments with homogeneous resources that are acquired in the market. These combinations can generate heterogeneous, specific non-tradable resources, which are a potential source of superior competitive advantage and, hence, performance. In order to operationalize this idea empirically, we analyse the development of internationalization resources (considered a specific category of non-tradable resources) within family and non-family firms. Compared to non-family firms, we argue that family firms are able to combine a particular type of heterogeneous initial resource (i.e. familiness) with homogeneous tradable resources acquired in the market. This question is tested using a panel of family and non-family Spanish manufacturing firms for the period 1990 to 2010. As a result, this study contributes to the literature on RBT, extending previous theoretical and empirical research in this stream.
