The aim of this paper is to demonstrate the importance of Bateson and colleagues' double bind theory, which has been a breakthrough in the history of psychiatry and human behavior because it freed us from the prison of ordinary logic.

The use of non‐ordinary logic, in understanding and in solving seemingly bizarre, over‐the‐lines human behavior, with its three different components: logic of paradox, logic of contradiction and logic of belief.

This paper presents the work carried out by the Centro di Terapia Strategica of Arezzo, which following the MRI approach, has put together seemingly simple solution to intimidating complex problems.

With the help of literature and practical‐clinical examples, this paper puts forward the use of non‐ordinary logic in brief strategic therapy in designing simple solutions to complex human problems such as phobias, obsessive compulsive disorders, presumed psychosis and other pathologies.

This work helps therapists and other care‐gives liberate themselves from the constraining chains of ordinary logic, in order to be able to solve human problems that seem unsolvable.

This paper develops from the constructivistic premise that our reality is a computation rather than a representation. Provides a constructive critique on the rigid psychopathological classifications used in mental health that end up creating a conditioned self‐confirming reality.

Proposes to present an approach, which moves away from the traditional rigid categorizing definitions of mental disorders, to a constructivist perspective that considers human problems as dysfunctional systems of perception and reaction to reality.

Provides literature that demonstrates how humans use interpretative tools to give order and definition to the world around them, but most often, end up forgetting that all their classifications, theories, tests and so forth, are mere human inventions. Presents various distinctive scientific research which evidence how those who are invested with the power of diagnosing mental sanity or insanity, are often trapped in their own theories and resulting diagnostic practice.

This paper puts forward the need in replacing a rigid deterministic model by an elastic and self‐corrective constructive‐strategic model of knowledge and intervention that guarantees the real efficacy and effectiveness of therapy.

The purpose of this paper is to analyse the relationship between the price of extra virgin olive (EVO) oil and its main quality attributes, in the specific case of business-to-consumers electronic commerce (B2C EC) channel. The final objective is to provide useful insights for small and medium-sized enterprises (SMEs) interested in online selling of EVO.

A hedonic price model was estimated considering the following attributes: packaging, cultivar composition, organic certification, oil extraction method, origin certification and localization of selling firms. A survey was performed in 2012 considering 169 virtual stores of SMEs (farms, mills and bottlers) located in all the main Italian olive-growing areas. A data set of 667 references was used to estimate the implicit prices of considered attributes.

The EVOs sold through virtual stores are highly differentiated on the basis of several quality attributes among which the most important is the certification of origin (protected denominations of origin/protected geographical indication). Therefore the firm location could generate considerable advantages or disadvantages in adopting a B2C EC strategy.

Future researches should develop a comparison between the premium prices and costs associated to each attribute in order to find the best product differentiation strategy. An accurate analysis about the implementation and management costs of EC systems as well as an examination of interactions between online and offline sale channels is needed. It would be useful to compare the manufacturer direct sell business model with other business model.

Few studies applied the hedonic price model to analyse the retail olive oil market. Nevertheless, no studies have analysed the market of EVO sold in virtual shops.

This study aims to identify the price determinants of fine wines in a small and competitive market. These characteristics are found in many lesser-known wine-producing countries and are often difficult to analyse because of lack of data.

This study hand-collects and transcribes wine-related data for 149 Swiss wineries and 2,454 individual wines over the period 2014–2018 directly from wine lists provided by wineries. This study uses multivariate ordinary least squares regressions to analyse the relation between wine attributes and prices and to assess the effect of a currency shock caused by the sudden appreciation of the Swiss franc in 2015 as well as a reduction in information asymmetries induced by the novel coverage of Swiss wines by The Wine Advocate.

Prices mainly depend on collective reputation, production techniques and product positioning. Surprisingly, following a sharp appreciation of the Swiss franc, producers did not reduce prices. The arrival of a highly influential wine expert on the market also had a positive price effect on rated wines and producers. Both hint at wineries attempting to position themselves relative to competitors.

Few studies examine the price drivers in lesser-known wine markets, where competition is fierce. This study’s results show that wine pricing differs from other more famous and larger wine regions. In addition, to the best of the authors’ knowledge, this study is also the first to analyse the impact of a currency shock and a reduction in information asymmetries on wine prices.
