Reti e stili di attaccamento nell'adattamento di coppia
No full textDiverse ricerche hanno studiato il funzionamento e l’adattamento di coppia alla luce dell’attaccamento romantico, rilevando in genere una relazione fra insicurezza del soggetto e minore adattamento diadico. In ambito italiano, ad esempio, Santona e Zavattini (2007) hanno riscontrato una relazione negativa fra l’adattamento di coppia e la dimensione dell’evitamento dalla vicinanza e dell’intimità nell’attaccamento. La presente ricerca aveva l’obiettivo approfondire tale tematica, analizzando le interconnessioni fra l’adattamento di coppia, l’attaccamento romantico del soggetto e del partner (così come autovalutato dal partner e come percepito dal soggetto stesso) e le reti di attaccamento dei componenti della coppia.
METODO. Alla ricerca hanno partecipato 50 coppie stabili di adulti (metà coppie con figli e metà senza), per un totale di 100 soggetti sposati o conviventi (età: 23-59 anni), ai quali sono stati somministrati i seguenti strumenti: (1) Il questionario Experiences in Close Relationships-Revised (ECR-R; Fraley, Waller, & Brennan, 2000; Calvo, 2008) per la valutazione dell’attaccamento adulto nelle relazioni sentimentali; (2) il questionario Attachment Network Questionnaire-Revised (ANQ-R; Doherty & Feeney, 2004; Calvo & de Romano, 2008), per valutare la composizione e le caratteristiche delle reti di attaccamento del soggetto; (3) il Relationship Questionnaire riferito al partner (RQP), ovvero un riadattamento del questionario di Bartholomew e Horowitz (1991) per valutare la percezione del soggetto riguardo allo stile di attaccamento del proprio partner; (4) la Dyadic Adjustment Scale (DAS; Spanier, 1976), un questionario multidimensionale per misurare il grado di adattamento di coppia e la rappresentazione che il soggetto ha della qualità della relazione con il partner.
RISULTATI. I risultati preliminari hanno evidenziato una chiara relazione fra l’attaccamento romantico e l’adattamento di coppia. In sintesi: (1) i soggetti più insicuri nell’attaccamento romantico percepiscono la loro relazione di coppia come meno adattata e soddisfacente, (2) anche l’insicurezza dell’attaccamento del partner influenza negativamente la soddisfazione di coppia del soggetto; (3) al crescere della soddisfazione e dell’adattamento diadico, il partner tende ad assumere una posizione di maggiore rilevo all’interno della rete di attaccamento del soggetto
Stabilizing a previously centrally planned economy: Poland 1990
No full textWe examine the dynamics of the January 1990 stabilization programme in Poland, focusing on the substantial and sudden collapse in industrial output, and inflation persistence. We discuss three, non-mutually exclusive, explanations of these phenomena: excessive initial stocks of inventories, an exogenous fall in household demand and tight credit. We conjecture that tight credit was at centre stage: it helped to magnify the fall in output, and to coordinate such a fall across sectors. We base such a conjecture on the existence of substantial credit segmentation, and on the underdevelopment of private credit markets. This conjecture is further strengthened by the fact that wages increased, and even went beyond the programme's ceilings, as credit expanded during the year. We argue that the wage hike may be the reason why credit expansion did not result in a major output recovery, and inflation persisted during the year. There are discussions of this article by M. Burda and G. W. Kolodko, pp 209-212. -from Author

Hydraulics of a physical model of supercritical vortex drop shaft
No full textVortex drop shafts are special drop structures typically installed in urban drainage systems or rarely as spillways for hydropower plants. The knowledge about the hydraulic behavior of vortex drop shafts was improved over the years but some gaps still have to be filled, with particular concern to the hydraulic aspects of the intake structure and of the vertical shaft. In this paper, an experimental campaign on a reduced-scaled physical model of vortex drop shaft serving an urban sewer system is described. Free-surface observations were used to characterize the hydraulics of the spiral inlet at the head of the shaft. A computational procedure based on the momentum approach is applied to derive velocity and flow rotation angle profiles over the vertical shaft. Such hydraulic features are fundamental into the design of a vortex drop shaft. If they are known with a sufficient reliability, then the energy dissipation efficiency of the shaft can be easily derived
Welfare implications of Calvo vs. Rotemberg pricing assumptions
No full textThis paper compares the welfare implications of two widely used pricing assumptions in the New-Keynesian literature: Calvo-pricing vs. Rotemberg-pricing. We show that despite the strong similarities between the two assumptions to a first order of approximation, in general they might entail different welfare costs at higher order of approximation. In the special case of non-distorted steady state, the two pricing assumptions imply identical welfare losses to a second order of approximation.

Hacia un nuevo Fiat Lux: María Zambrano y Agustín G. Calvo en diálogo
No full textThe main purpose of this research is to initiate a lively and enriching conversation with two
distinguished twentieth century thinkers, María Zambrano and Agustín G. Calvo. For these
authors, there can be no true liberation or awakening from the long nightmare of History, without
a radical questioning of some basic beliefs that conform our Western Culture such as the
concept of individual or the concept of democracy. Throughout this study, we will try to
analyse the contradictions inherent to the formation of the mass-man and the States, which both
Zambrano and García Calvo strove to unveil guided by that common yearning to get out of
bewilderment and embrace a new clarity, a new Fiat Lux.Con la presente investigación pretendemos entablar una conversación viva y enriquecedora
entre dos insignes pensadores del siglo XX, María Zambrano y Agustín G. Calvo. Para ambos
autores no puede existir una verdadera liberación o despertar de esta interminable pesadilla que
es la Historia, sin un cuestionamiento radical de algunas de las categorías conceptuales básicas
que conforman nuestra cultura occidental tales como el concepto de individuo personal o el concepto
de democracia. A lo largo del estudio trataremos de analizar las contradicciones inherentes
a la propia constitución del hombre-masa y de los Estados, que tanto Zambrano como García
Calvo se esforzaron por desvelar en ese anhelo común de salir de la confusión y caminar hacia
una nueva claridad, un nuevo Fiat Lux
The Impact of Administration and Inquiry on Rorschach Comprehensive System Protocols in a National Reference Sample
No full textWe investigated the impact of administration and inquiry skills on Rorschach Comprehensive System (CS; Exner, 1974, 1991, 1993) protocols collected for the Italian adult nonpatient reference sample. The same research team collected CS protocols on two occasions. The initial reference sample (N = 212; Lis, Rossi, & Prina, 1998) was collected under the supervision of experienced psychologists who carefully studied CS administration and scoring procedures (Exner, 1986, 1990, 1993). The second sample (N = 101; Lis, Zennaro, Calvo, & Salcuni, 2001) was collected after the team obtained additional and sustained CS training from Rorschach workshops certified instructors. Both samples were scored, reliably but they showed large differences on many codes, with protocols from the second sample being richer and more complex than the first. The results indicate that administration skills can have a dramatic impact on CS protocols and may contribute to variations in samples collected by different investigators. Training standards should be devised to insure uniform administration procedures are followed when collecting CS protocols
Calvo vs. Rotemberg in a Trend Inflation World: An Empirical Investigation
No full textThis paper estimates and compares new-Keynesian DSGE monetary models of the business cycle derived under two different pricing schemes - Calvo, Rotemberg - and a positive trend inflation rate. Our empirical findings (i) support trend inflation-equipped models as better fitting during the U.S. great moderation period, (ii) provide evidence in favor of the statistical superiority of the Calvo setting, and (iii) suggest the absence of price indexation under the Calvo mechanism only. Possibly, the superiority of the Calvo model (against Rotemberg) is due to the restrictions implied by such pricing scheme for the aggregate demand equation. The determinacy regions associated to the two estimated models indicate relevant differences in the implementable simple policies. Our findings call for the development of monetary policy models consistently embedding a positive trend inflation rate and possibly based on a Calvo pricing scheme
Leopoldo Calvo-Sotelo y la Transición exterior: la prioridad europea
No full textLeopoldo Calvo-Sotelo played an important role in Spain’s transition to democracy, serving as minister and later prime minister. His political career was closely linked to Foreign Affairs and to the process of the “Foreign Transition” as he liked to call it. This paper, largely based upon his personal archives, analyses his thought, and how his idea of Europe played an important role in the formulation and execution of his policy. Calvo-Sotelo’s ideas and achievements are compared with those of other political leaders of the time, such as Adolfo Suárez and Felipe González. The conclusions show the nature and characteristics of Leopoldo Calvo-Sotelo’s pro-European ideas.Leopoldo Calvo-Sotelo desempeñó importantes responsabilidades ejecutivas en los gobiernos de la Transición, incluida la presidencia del Gobierno. Su gestión estuvo intensamente vinculada a las relaciones exteriores, dentro del proyecto que él mismo denominó «transición exterior». El artículo, basado en buena medida en documentación conservada en su archivo personal, analiza cuáles fueron sus principales ideas y en qué medida su concepto de Europa desempeñó un papel relevante en la formulación y ejecución de su política. Analiza esos hechos en relación con otros dirigentes del momento, especialmente Adolfo Suárez y Felipe González. Las conclusiones permiten conocer en qué consistió el europeísmo del principal protagonista de estos hechos
