Prescribing the Families Own Dysfunctional Rules as a Therapeutic Strategy*

The use of paradox-strategy in therapy is motivated by the fact that many families request help but at the same time seem to reject all offers of help. The therapist may be drawn into a game in which every effort on his part to act as an agent of change is nullified by the family group. In systemic terms these contradictory attitudes derive from the dynamic equilibrium existing between the tendency toward change, which is implicit in the request for help at one level, and the tendency toward homeostasis which at another level imposes the repetition of the family's habitual rules of interaction. The coexistence of these forces can entangle the therapist in the family's paradoxical logic of “help me to change, but without changing anything.” By accepting the contradiction facing him and by “uniting” himself with this within the family, the therapist puts himself into a position opposite to that which the family expects. His response to the family's paradoxical request is a paradox, or counterparadox, because it creates the contradictory communication typical of rigid family systems. By prescribing its own dysfunctional rules to the family, the therapist can stimulate the tendencies toward change present in the family system.     

A non linear wavelet based estimator for long memory processes

Two wavelet based estimators are considered in this paper for the two parameters that characterize long range dependence processes. The first one is linear and is based on the statistical properties of the coefficients of a discrete wavelet transform of long range dependence processes. The estimator consists in measuring the slope (related to the long memory parameter) and the intercept (related to the variance of the process) of a linear regression after a discrete wavelet transform is performed (Veitch and Abry, 1999). In this paper its properties are reviewed, and analytic evidence is produced that the linear estimator is applicable only when the second parameter is unknown. To overcome this limitation a non linear wavelet based estimator - that takes into account that the intercept depends on the long memory parameter - is proposed here for the cases in which the second parameter is known or the only parameter of interest is the long memory parameter. Under the same hypothesis assumed for the linear estimator, the non linear estimator is shown to be asymptotically more efficient for the long memory parameter. Numerical simulations show that, even for small data sets, the bias is very small and the variance close to optimal.

Modelling the quality of work in the Italian social co-operatives combining NPCA-RSM and SEM-GME approaches

The objective of this paper is to describe and analyse with appropriate statistical models the links between work quality latent factors. Due to the complexity of the task, the analysis is carried out through a two-step approach:

• In the first step, we construct some multidimensional measures of the subjective quality of work, using nonlinear principal component analysis (NPCA) and Rasch analysis with the Rating Scale Model (NPCA-RSM);

• In the second step, we adopt a Structural Equation Model based on generalized maximum entropy (SEM-GME) to integrate the measures achieved with the previous step and to evaluate the relationships between the subjective work quality latent factors.

Therefore, the novel aspects of this paper are the following: (i) The integration between the NPCA-RSM and SEM-GME, which allows reduction of the variables analysed and evaluation of the measurement errors; (ii) The formalization of a Job Satisfaction Model for the study of the relationships between the subjective work quality latent factors in the Italian social services sector.     

A two-phase optimization method for a multiobjective vehicle relocation problem in electric carsharing systems

A spanning subgraph F of a graph G is called an even factor of G if each vertex of F has even degree at least 2 in F. It was conjectured that if a graph G has an even factor, then it has an even factor F with \(|E(F)|\ge {4\over 7}(|E(G)| + 1)+ {2\over 7}|V_2(G)|\), where \(V_2(G)\) is the set of vertices of degree 2 in G. We note that the conjecture is false if G is a triangle. In this paper, we confirm the conjecture for all graphs on at least 4 vertices, and moreover, we prove that if \(|E(H)|\le {4\over 7}(|E(G)| + 1)+ {2\over 7}|V_2(G)|\) for every even factor H of G, then every maximum even factor of G is a 2-factor consisting of even circuits.     

Labour Mobility in Italy: An Empirical Investigation

ABSTRACT: In this paper the author presents a model of unemployment inflows and outflows for the Italian labour market. The flows that the author attempts to estimate are the unemployment inflows and outflows from and to employment. The aggregate estimation suggests that a crucial role is played by the aggregate demand and wage variables, and by the structural change variable. The paper also presents intersectoral estimations of SURE, which take into consideration the flows between Industry and Services. The results are along the lines of those obtained at the aggregate level. An important factor which should be underlined, however, is the asymmetric pattern of the wage variable in the industrial and services sector.     

Engaging Fathers in Family Therapy with Violent Adolescents

Violent behavior in adolescents can often signal profound distress or pain arising from family conflicts, hostile marital separations, sudden losses and other family turmoil. By circumventing blame the therapist engages the family in a constructive process that allows adolescents to change and grow and parents to share pain and sorrow about their own issues and responsibilities for their children. This re‐establishes healthy generational boundaries, produces a clearer co‐parenting alliance (e.g. after divorce) and creates sibling support. This paper describes an experiential approach, for working with violent adolescents in family therapy influenced by the pioneer work of Satir and Whitaker. It integrates systemic and developmental theories linking the presenting problem to relevant family events. The therapist: (1) explores adolescent development in the family and social context; (2) establishes a therapeutic alliance through understanding the interpersonal context for violent behavior, and (3) re‐directs negative actions into positive connections with family members. Segments of family therapy sessions with two adolescent boys and their families from different cultural backgrounds illustrate the impact of paternal absence for adolescent well‐being and the need to actively engage fathers in family therapy. Mario, the father's ‘tumor’, and Juan with his despairing violence are two problematic adolescents brought to therapy because of their aggressive behavior at home and/or in the school. The paper describes how to give them a different voice and build a therapeutic alliance with the family.     

Implementing lean information management: the case study of an automotive company

Worldwide modern organisation is continuously crossed by a great number of information but frequently information is not accurate, the needed information is not generated or it cannot be easily identified and, more, the information cannot flow through the whole organisation. This paper proposes the application of lean thinking in the field of information management. In the areas of manufacturing and production, the lean thinking is well known but usually the importance of a holistic approach is neglected and the improvement involves only the production and logistic areas and there is not a specific focus on the lean information management. We applied lean thinking to information management in order to improve the performance of an automotive company. We analysed the as-is company condition, we identified the present muda and we introduced the necessary changes. Then, we verified the modification efficiency through the calculation of a performance index. The paper proposes an interesting and exhaustive case of lean information management application and it highlights the possible improvement of such approach. The results of this study are not sector specific: they are not only applicable by other automotive industries, but they can also be extended to many other sectors.     

The Easterlin paradox and the decline of social capital: An integrated explanation

During the most recent decades people in the US have reported both a stagnant or even declining subjective well-being, as Easterlin (Easterlin, R.A., 1974. Does economic growth improve the human lot? Some empirical evidence. In: David, P.A., Melvin, W.R. (Eds.), Nations and Households in Economic Growth. Academic Press, New York, pp. 89–125) originally observed, and deterioration in their social and family ties, as Putnam (Putnam, R.D. (2000). Bowling Alone. Simon&Schuster, New York) has claimed. The paper proposes an integrated explanation of these two stylised facts by extending the analysis of the relative income explanation of the Easterlin paradox to social relationships as enjoyable ends of choice. Drawing on the evidence-based results of psychology, the paper constructs a model whose premises are (i) that individuals produce social relationships by means of relational ability, (ii) that this ability is primarily shaped during infancy, and (iii) that commercial pressure on children to consume in competition with others may displace the enjoyment of social relationships. The model is thus also able to explain the case of rich countries, like Sweden, that devote relatively more human and material resources than the US to children and adolescents, and that experience both increasing subjective well-being and improving social capital.
