The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality
2010
A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…
Who Can See My Stuff? : Online Self-Disclosure and Gender Differences on Facebook
2018
This study investigates the gendered privacy practices and concerns on Facebook, by leaning on the idea of privacy management as a form of digital labour. We analyse if young Facebook users are more concerned about the privacy against other users than against Facebook as a company or against third-party partners. We also analyse if privacy concerns and visibility rules are differentiated by gender. Using a structured online survey, we collected responses from a sample of 813 Italian university students (aged 18-34). Our results show that the respondents have just slightly more privacy concerns against other users than against Facebook, and much less against third-party partners. Unlike a ma…
Sense of quality of life and self-discrepancy - differences between social science and technology students
2020
The main purpose of the research is to determine personality predictors related to a new model of the sense of quality of life in a diverse group of students. The study is based on the self-discrepancy theory developed by Higgins, and the Personality and Axiological Model developed by Mróz. Method. Sixty four (64) pedagogy students and 62 electrical engineering students were the subjects of the research. The Adjective Check List test (ACL), the Modified Quality of Life Questionnaire as well as interview and observation were applied in the research. Results. Individuals with low self-discrepancy achieved significantly better results in Competences, Relationships, and Autonomy as part of the …
Trait Self-Control, Social Cognition Constructs, and Intentions: Correlational Evidence for Mediation and Moderation Effects in Diverse Health Behavi…
2019
Background: We examined effects of trait self‐control, constructs from social cognition theories, and intentions on health behaviours. Trait self‐control was expected to predict health behaviour indirectly through theory constructs and intentions. Trait self‐control was also predicted to moderate the intention–behaviour relationship. Methods: Proposed effects were tested in six datasets for ten health‐related behaviours from studies adopting prospective designs. Participants (N = 3,249) completed measures of constructs from social cognition theories and self‐control at an initial time point and self‐reported their behaviour at follow‐up. Results: Results revealed indirect effects of self‐co…

Emotional self-regulation through music in 3-8-year-old children
2009
The current study explored the role of music in children’s emotional self-regulation. Music is shown to be a common and effective way of self-regulating emotions in adolescence and adulthood. It is also widely known that parents use music to regulate the emotions of their babies, for instance in calming them down by lullabies. However, very little is known about how children themselves use music for emotional needs, and how the self-regulatory emotional engagement develops. A survey study was conducted with parents of 63 children including 37 boys and 26 girls, aged between 2.9 to 8.1 years. The parents answered questions about their child’s musical activities, preferences, and emotion-regu…

The paper is a closure to a previous article.
Simple flume with a central baffle
2016
Abstract In this paper the stage-discharge relationship of a flume with a central baffle is theoretically deduced using the Buckingham-Theorem of the dimensional analysis and the self-similarity theory. The new stage-discharge equation is calibrated by the measurements carried out by Peruginelli and Bonacci using a baffle having a given throat length and five different values of the contraction ratio. Finally, for a given throat length, a relationship linking the discharge with the upstream water depth, the contraction ratio and the contracted width is deduced.
New Stage–Discharge Relationship for Triangular Broad-Crested Weirs
2022
Simple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non-uniform velocity profile, and streamline curvature due to weir contraction). In this paper, the dimensional analysis and the incomplete self-similarity theory are used to investigate the outflow process of triangular broad-crested weirs, characterized by different values of the ratio between crest height p and channel width B, and to theoretic…
Negotiating an identity : the mediated discursive self-representation of the Polish immigrant community in the UK
2017
The chapter investigates the mediated entextualizations of the identities of Polish immigrants to the UK in the period of post-crisis politics and economic reforms. The media discourse studied is collected from MojaWyspa.co.uk (MyIsland), one of the largest Polish-language online hubs designed for the substantial Polish community living on the British Isles. The study shows which discursive strategies of othering are employed to delimit the Polish immigrants’ collective identity, which self/other-presentation techniques are used, and how this group identity is legitimized argumentatively. It examines the linguistic realizations of self/other reference, active/passive and positive/negative p…
