A pilot study of the Italian adaptation of the Session Evaluation Questionnaire fourth version

Abstract The Session Evaluation Questionnaire (SEQ) evaluates the impact of counselling and psychotherapy sessions; it may be conceived as a bridge between psychotherapy process and outcome. SEQ is a self-report tool asking patients about their experience with the clinical session just ended; it consists of 27 adjectives in semantic differential scale, divided into three thematic parts: evaluation of the session itself, feelings after the session, and evaluation of the therapist. Even if the original American SEQ has been translated into many languages, only a few translations have been validated. This is a pilot study, which attempted to replicate the five-dimensional structure of the fourth version of the Anglo-American SEQ, for the Italian population. Data were collected on 111 outpatients attending the Psychological Assistance Service (SAP-Dynamic Psychotherapy Service) of Padua University, after their first two clinical interviews. Exploratory factor analyses (PCA with varimax rotation) were performed on each of the three parts of the SEQ. Results confirmed the original factorial structure, showing a substantial agree for Depth, Smoothness, Positivity and Arousal dimensions; Good Therapist dimension overlapped perfectly with the original one. The Italian SEQ showed adequate internal consistency (Cronbach\u2019s alphas ranged .65 to .86 for the five subscales). Convergent validity measured with an index of perceived satisfaction in the counselling process, showed significant positive correlations with Good Therapist, Depth and Positivity scores. The preliminary results of this pilot study show that the Italian SEQ results in a reliable instrument to measure the impact of clinical sessions. Of course, validation studies are needed, especially to replicate the factor structure of the instrument and to better assess its validity

A uniform definition of stochastic process calculi

We introduce a unifying framework to provide the semantics of process algebras, including their quantitative variants useful for modeling quantitative aspects of behaviors. The unifying framework is then used to describe some of the most representative stochastic process algebras. This provides a general and clear support for an understanding of their similarities and differences. The framework is based on State to Function Labeled Transition Systems, FuTSs for short, that are state-transition structures where each transition is a triple of the form (s; α;P). The first andthe second components are the source state, s, and the label, α, of the transition, while the third component is the continuation function, P, associating a value of a suitable type to each state s0. For example, in the case of stochastic process algebras the value of the continuation function on s0 represents the rate of the negative exponential distribution characterizing the duration/delay of the action performed to reach state s0 from s. We first provide the semantics of a simple formalism used to describe Continuous-Time Markov Chains, then we model a number of process algebras that permit parallel composition of models according to the two main interaction paradigms (multiparty and one-to-one synchronization). Finally, we deal with formalisms where actions and rates are kept separate and address the issues related to the coexistence of stochastic, probabilistic, and non-deterministic behaviors. For each formalism, we establish the formal correspondence between the FuTSs semantics and its original semantics

Therapists' clinical work between sessions: A preliminary study of the Post Session Therapist Questionnaire

Objective: In this paper, we present the development of a new self-report questionnaire to assess a characteristic of clinical work that has not been considered in the literature: the mental (affective and rational) work that therapists do between clinical sessions. The resulting instrument is the Post Session Therapist Questionnaire. Method: After consulting the literature and conducting in-depth discussions of the dimensions to be investigated, we generated 40 items through brainstorming. We had 16 experts carefully examine the questionnaire\u2019s content validity at various stages and thus obtained 38 pertinent, clear, and unambiguous items. The experts also provided positive evaluations of the questionnaire\u2019s instructions and response mode. We then carried out a pilot study with 27 clinicians, who filled out the questionnaire twice, referring to 100 patients in each case. To assess the structural validity of the new instrument, we conducted an exploratory factor analysis using the session (N = 200) as the unit of analysis. Result: Three factors substantially supported the theoretical dimensions that we conceptualized in the first stage of the research: We called the factors Positive Regard, Comprehension, and Diagnostic Effort. These dimensions have good internal consistency. Conclusion: The study\u2019s results suggest that these clinical dimensions are meaningful in the development of clinical processes, which encourages further study of the psychometric properties of the questionnaire, with larger samples, so as to consider these results in relationship to the outcomes of the following sessions

MarCaSPiS: a Markovian Extension of a Calculus for Services

Service Oriented Computing (SOC) is a design paradigm that has evolved from earlier paradigms including object-orientation and component-based software engineering. Important features of services are compositionality, context-independence, encapsulation and re-usability. To support the formal design and analysis of SOC applications recently a number of Service Oriented Calculi have been proposed. Most of them are based on process algebras enriched with primitives specific of service orientation such as operators for manipulating semi-structured data, mechanisms for describing safe client-service interactions, constructors for composing possibly unreliable services and techniques for services query and discovery. In this paper we show a versatile technique for the definition of Structural Operational Semantics of MarCaSPiS, a Markovian extension of one of such calculi, namely the Calculus of Sessions and Pipelines, CaSPiS. The semantics deals in an elegant way with a stochastic version of two-party synchronisation, typical of a service-oriented approach, and with the problem of transition multiplicity while preserving highly desirable mathematical properties such as associativity and commutativity of parallel composition. We also show how the proposed semantics can be naturally used for defining a bisimulation-based behavioural equivalence for MarCaSPiS terms that induces the same equalities as those obtained via Strong Markovian Equivalence

The Role of Non-Verbal Interaction in a Short-Term Psychotherapy: Preliminary Analysis and Assessment of Paralinguistic Aspects

Analysis at a paralinguistic level of communication, already conceptualized within the multiple code theory, would appear to be very important in order to fully describe the quality of the patient-therapist relationship. In this study the therapeutic process and microprocess are analyzed taking into consideration a specific paraverbal aspect (speech rate) present in patient and therapist's communication. More specifically, in this paper we aim to investigate the relationship between the speech rate of both patient and therapist with the linguistic aspects of their referential process as obtained by the IDAAP dictionaries, relating to three sessions belonging to different phases of the psychotherapy. The results show that there are many significant correlations between the considered values. These findings are interpreted as an expression of the alignment between patient and therapist which can be linked to the outcome of the psychotherapy.</p

Beyond Verbal Behavior: An Empirical Analysis of Speech Rates in Psychotherapy Sessions

Objective: The present work aims to detect the role of the rate of speech as a mechanism able to give information on patient's intrapsychic activity and the intersubjective quality of the patient–therapist relationship. Method: Thirty clinical sessions among five patients were sampled and divided into idea units (N = 1276) according to the referential activity method. Each idea unit was rated according to referential activity method and in terms of speech rate (syllables per second) for both patient and therapist. A mixed-effects model was applied in order to detect the relationship between the speech rate of both the patient and the therapist and the features of the patient's verbal production in terms of referential activity scales. A Pearson correlation was applied to evaluate the synchrony between the speech rate of the patient and the therapist. Results: Results highlight that speech rate varies according patient's ability to get in touch with specific aspects detected through referential activity method: patient and the therapist speech rate get synchronized during the course of the sessions; and the therapist's speech rate partially attunes to the patient's ability to get in touch with inner aspects detected through RA method. Conclusion: The work identified speech rate as a feature that may help in the development of the clinical process in light of its ability to convey information about a patient's internal states and a therapist's attunement ability. These results support the intersubjective perspective on the clinical process

The Active Role of Students, Teachers, and Stakeholders in Managing Economic and Cultural Value, Urban and Built Heritage

Innovation in architecture education is increasingly oriented towards the analysis of real problems considered in their complexity and multi-dimensionality and the active involvement of the stakeholders. The aim of this paper is to highlight how the active role of stakeholders can improve the economic and cultural value of enhancement projects developed in architecture and planning schools, focusing on the potentialities of the problem-based learning (PBL) approach. A three-step educational procedure based on the PBL approach, applied at the atelier “Heritage Preservation and Enhancement” of the Politecnico di Torino, is presented. The results showed how a continuous interaction and dialogue with teachers and stakeholders can effectively support students in addressing real problems and in developing sustainable and feasible enhancement projects able to integrate heritage preservation and economic-financial issues.

Conversión de residuos sólidos urbanos en energía

Given Uruguay’s energetic situation, where its main energy sources are from&nbsp;hydroelectric and thermal power from fossil fuels, it is important to consider other energy&nbsp;sources such as Energy from Waste. Waste to Energy (WTE) or Energy from Waste is a&nbsp;Municipal Solid Waste (MSW) management system, which results in an appropriate and&nbsp;sustainable use of the waste which cannot be efficiently recycled or reused. This articleoverviews the different WTE alternatives and proposes a concrete small-scale application for the&nbsp;city of Paysandú.Ante la situación energética del Uruguay, donde sus principales fuentes energéticas&nbsp;son a través de centrales hidráulicas y centrales térmicas a partir de combustibles fósiles, es&nbsp;importante considerar otras fuentes de energía como ser el recurso energético de los residuos.&nbsp;Recuperación de Energía de los Residuos o Waste-to-Energy (WTE), por su sigla en inglés, es un&nbsp;sistema de gestión para la disposición de los residuos sólidos urbanos (MSW, Municipal Solid&nbsp;Waste) que permite un uso adecuado y sostenible de los residuos que no pueden ser&nbsp;eficientemente reciclados o reutilizados. El presente artículo presenta las diferentes alternativas&nbsp;existentes para generar energía a partir de residuos y propone un caso concreto de aplicación de&nbsp;pequeña escala, utilizando un Sistema de Oxidación por Batch para la ciudad de Paysandú, Uruguay

Towards a logic for performance and mobility

Klaim is an experimental language designed for modeling and programming distributed systems composed of mobile components where distribution awareness and dynamic system architecture configuration are key issues. StocKlaim [R. De Nicola, D. Latella, and M. Massink. Formal modeling and quantitative analysis of KLAIM-based mobile systems. In ACM Symposium on Applied Computing (SAC). ACM Press, 2005. Also available as Technical Report 2004-TR-25; CNR/ISTI, 2004] is a Markovian extension of the core subset of Klaim which includes process distribution, process mobility, asynchronous communication, and site creation. In this paper, MoSL, a temporal logic for StocKlaim is proposed which addresses and integrates the issues of distribution awareness and mobility and those concerning stochastic behaviour of systems. The satisfiability relation is formally defined over labelled Markov chains. A large fragment of the proposed logic can be translated to action-based CSL for which efficient model-checkers exist. This way, such model-checkers can be used for the verification of StocKlaim models against MoSL properties. An example application is provided in the present paper
