The Harris Extended Exponential Distribution

A new lifetime distribution is proposed and studied. The Harris extended exponential is obtained from a mixture of the exponential and Harris distributions, which arises from a branching process. Several structural properties of the new distribution are discussed, including moments, generating function and order statistics. The new distribution can model data with increasing or decreasing failure rate. The shape of the hazard rate function is controlled by one of the added parameters in an uncomplicated manner. An application to a real dataset illustrates the usefulness of the new distribution.     

Information Percolation With Equilibrium Search Dynamics

We solve for the equilibrium dynamics of information sharing in a large population. Each agent is endowed with signals regarding the likely outcome of a random variable of common concern. Individuals choose the effort with which they search for others from whom they can gather additional information. When two agents meet, they share their information. The information gathered is further shared at subsequent meetings, and so on. Equilibria exist in which agents search maximally until they acquire sufficient information precision and then search minimally. A tax whose proceeds are used to subsidize the costs of search improves information sharing and can, in some cases, increase welfare. On the other hand, endowing agents with public signals reduces information sharing and can, in some cases, decrease welfare.     

Estimating the time elapsed since first marriage with cross-section data

This article shows how Hajnal's method of estimating the mean age at first marriage with period data may be extended to estimate also the mean time elapsed since first marriage. The latter may thus be estimated in fertility analyses that exploit cross-section data even when the date of marriage is not known. However, simulations indicate that, under certain circumstances, such an estimate may be seriously biased. An application to data drawn from the 1981 Italian census is presented.On montre dans cet article comment la méthode d'Hajnal pour estimer l'âge moyen au premier mariage avec des données transversales, peut être généralisée pour estimer la durée moyenne écoulée depuis ce mariage. Cette durée peut être utilisée en vue d'analyses de fécondité faites à partir de données transversales, même lorsque la date du mariage n'est past connue. Des simulations sur ordinateur indiquent cependant que, sous certaines circonstances, une telle estimation peut être sérieusement biaisée. Une application à des données du recensement italien de 1981 est également présentée.     

A class of residuals for outlier identification in zero adjusted regression models

Zero adjusted regression models are used to fit variables that are discrete at zero and continuous at some interval of the positive real numbers. Diagnostic analysis in these models is usually performed using the randomized quantile residual, which is useful for checking the overall adequacy of a zero adjusted regression model. However, it may fail to identify some outliers. In this work, we introduce a class of residuals for outlier identification in zero adjusted regression models. Monte Carlo simulation studies and two applications suggest that one of the residuals of the class introduced here has good properties and detects outliers that are not identified by the randomized quantile residual.     

Market Embeddedness and Corporate Instability: The Ecology of Inter-industrial Networks

This paper studies the effect of inter-industrial control on the survival of Israeli firms. It examines how relationsbetweenenvironments modify relationswithinenvironments. More specifically, this paper studies how the social organization of the competition at the aggregate level (industry) affects outcomes at the individual (firm) level. Using trade data and national accounts statistics, we specify and test the hypothesis that an industry's corporate instability is negatively associated with its social capital (comprised from its market embeddedness and political embeddedness). Our findings show that industry's corporate instability within industries is associated with the industry's structural embeddedness in the network of input–output transactions, the degree of control it has over its external transactions, and its political leverage.     

The territories of the practices of the trench: Origins,scope, desire

Our work with children whose rights have been violated, with their families devastated by family violence and where the majority have been left out of the sociocultural systems and experiencing serious economic and educational difficulties, has taken us to our professional limit. The solitary and individual work, in the dim light of the office, left us without tools. As therapists, we can say that it has been necessary to break with our own mental schemes and to take a leap into the territory, the terrain itself. The learned university theories were questioned, forcing us to include a more humanising and less judgmental look at the work. A psychology of the trench was born for us. This paper articulates a work process that required something more than specific training in our subject matter. It summoned us as human beings capable of hosting suffering. From this starting point, and with an open mind and heart to go through its stages, this process is presented as a journey with advances and setbacks in its intervention modalities, systematising programs in permanent construction. Systematising practices is not an easy task. Familias Cuidando (Caring Families) and Adoptar es Posible (To Adopt is Possible) are the developmental spaces of our trench practices, practices that aim to accompany children, adolescents, and their families through the system of promotion and comprehensive protection of their rights. From Vicente López, a district in the province of Buenos Aires, our psycho-socio-educational and legal approach tries to be a link within collaborative and supportive practices; establishing ties, networks, and dialogues to strengthen the new paradigm aiming to support listening to the voice of children and adolescents; rescuing their childhoods, resignifying the different family models, and accompanying the construction of a life project for each one, in which we all fit.     

Cognitive reappraisal and need to belong predict prosociality in Mexican-origin adolescents

This 2-year longitudinal study examined Mexican-origin adolescents’ need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors). Prosocial behaviors, which are actions intended to benefit others, are hallmarks of social proficiency in adolescence and are influenced by intrapersonal abilities and motivations that typically develop during adolescence. Yet, few studies of Mexican-origin or other U.S. Latinx youths have examined whether such individual difference characteristics, specifically social motivation and emotion regulation skills, support prosocial behavior. In a sample of 229 Mexican-origin youth (M_age = 17.18 years, SD = .42, 110 girls), need to belong, cognitive reappraisal, and general prosocial behaviors were assessed at ages 17 and 19. Emotional and public forms of prosociality also were assessed at age 19. Cognitive reappraisal was positively associated with concurrent general prosociality at age 17, whereas need to belong was positively associated with concurrent public prosociality at age 19. Moderation analyses revealed that general and emotional types of prosocial behaviors at age 19 were lowest for youth with both lower need to belong and less use of cognitive reappraisal at 19 years. Greater cognitive reappraisal skills and need to belong may reflect distinct motivations for engaging in varying forms of prosocial behavior in late adolescence.
