The study aims to propose a systematic and innovative model of purchase intention development that integrates Theory of Planned Behaviour (TPB) with its main extensions and clarifies the logical status of the variables involved and the structure of the causal path. The TPB is the most useful predictive model of purchase intentions, which can be viewed as the product of various psychological determinants. Previous works have proposed extensions of the TPB model to selectively include knowledge, trust or social norms, but an integrated proposal has not yet been formulated. Based on a survey in four European countries (Germany, Italy, Poland and the UK; N = 1,035), this study tests the process of organic vegetable purchase intention development using a structural equation model (SEM). This comprises part of the measurement of latent variables and part of the analysis of dependency relationships (MLR estimation method). The results show that purchase intention for organic vegetables is primarily dependent on positive moral attitude (PoMA) towards such consumption. The inclusion of PoMA reduces the effect of attitude toward buying organic vegetables, but the effects of social norms, past behaviour and perceived behavioural control remain significant. This study proposes an innovative model to explain purchase intention for organic vegetables that incorporates the key current extensions of the TPB model (knowledge, trust and PoMA) into an integrated causal pathway. Understanding the relationships between the antecedents of purchase intention provides relevant information on “what” needs to be improved and “where” interventions are needed to steer consumers towards organic food.

Background: A growing number of studies reveal that there are significant associations between a patient’s perception of quality of care and a health professional’s perceived quality of work life. Previous studies focused on the patients or on the workers. Alternatively, they centre the discussion on either the negative or the positive effects, both on patients and care workers. This research work focuses on the positive relationship with patients - a possible resource for care workers. Method: Study 1: a CFA was conducted to test the factorial structure and the tenure of the Italian version for patients of the Customer-initiated Support scale. Study 2: using a multi-group path analysis, the effects of work characteristics and of the relationship with patients on burnout were tested in two different contexts: emergency and oncology ward. Results: Study 1: the one-factor instrument shows good reliability, convergent and divergent validity. Study 2: for oncology nurses cognitive demands, job autonomy, and support from patients have direct effects on emotional exhaustion and job autonomy; interactions between cognitive demands and patients’ support have an effect on depersonalization. For emergency nurses cognitive demands and interactions between job autonomy and support from patients have effects on emotional exhaustion; job autonomy, patients support and gratitude have direct effects on personal accomplishment. Conclusions: Results confirm expectations about the role of patients’ support and gratitude in reducing nurses’ burnout, with differences in the two contexts: emergency nurses show higher burnout and lower perception of positive relationship with patients, but present more intense protective effects of the interaction between job autonomy and support/gratitude. Suggestions can be offered to managers in developing interventions to promote “healthy organization” culture that consider jointly employees and patients’ needs.

The relationship between rape myth acceptance, gender-specific system justification, and bystander intention to intervene has often been studied on a one-dimensional, without separating the four dimensions of the acceptance of rape myths. The current study analyzes the relationship between the acceptance of rape myths, gender-specific system justification, and bystander intention to intervene, and explores whether the relationships operate differently for men and women. The sample was 3966 university students: 2963 from the University of Turin and 1004 from the Politecnico of Turin; 71.2% women and 28.8% men; average age 22.61 years. After descriptive analyses, independent sample T-test, and bivariate correlations, a model where the acceptance of four rape myths (“She asked for it”; “He didn’t mean to”; “It wasn’t really rape”; “She lied”) mediated the relationship between gender-specific system justification and bystander intention to intervene was tested on the whole sample and then separately on women and men. A bootstrapping procedure was applied. Our data show that for both men and women gender-specific system justification was related to the four rape myths, whereas women and men differed on the relationship between acceptance of rape myths and bystander intention to intervene: only the dimension “She asked for it” was significant for both groups; the dimension “It wasn’t really rape” was significant only for the men. Focusing on the differences in women and men regarding acceptance of rape myths can be fruitful for a theoretical deepening of the field and may inform the development of more successful prevention programs.

Purpose: The theory of planned behaviour (TPB) and its extensions are often used to explain intentions to perform sustainable behaviours. Emotions can provide the impetus for action and should be considered in high-involvement situations, such as sustainable food purchase decisions. Therefore, the aim of this research work was to investigate whether the addition of different types of emotions (self-related, social and pro-active) to the TPB main constructs – attitude (ATT), subjective norm (SN) and perceived behavioural control (PBC) – improves the explanation of intention to make two sustainable food purchase choices: purchase Fairtrade (FT) products and purchase through solidarity purchasing groups (SPGs).Design/methodology/approach: The present investigation was conducted by two studies using online questionnaires and focussing on purchasing FT food products (Study 1) and purchasing food through SPGs (Study 2). Stepwise regression models were run to explain the intention to purchase FT products (Study 1; N = 240) and the intention to purchase through SPGs (Study 2; N = 209).Findings: Results show that emotions increase the predictive validity of the TPB model. The study also highlights the importance to distinguish between different types of emotions. Amongst those considered in both studies, only pro-active emotions play a significant role in predicting food purchasing intention. Results encourage further investigation of the role of emotions in TPB-based models for predicting sustainable food purchase choices.Research limitations/implications: The measurement of the three classical antecedents of the TPB model (ATT, SNs and PBC) performed by single items can be considered the main limitation of this work. In future research, instruments made up of more items measuring these three theoretical dimensions should be used. In addition, it would be important to conduct an analysis of the beliefs that determine ATTs, norms and perceived control.Originality/value: Different from previous studies that considered emotions in extension of the TPB model to explain sustainable behaviours, the present work separately analysed the role of three different kinds of emotions (self-related, social and pro-active) in explaining sustainable food behaviours.

New measurements of the η and K⁰ masses have been performed using decays to 3π⁰ with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects, the results M(η)=547.843±0.051 MeV/c² and M(K⁰)=497.625±0.031 MeV/c² were obtained.
