- Effects of the Interculturality and Mindfulness Program (PIM) on university students: a quasi-experimental studyPublication . Chiodelli, Roberto; Jesus, Saúl; Mello, Luana Thereza Nesi de; Andretta, Ilana; Oliveira, Diana; Costa, Maria Emília Santos; Russell, TamaraRates of mental health issues have been increasing among university students. This study investigates the effects of the Interculturality and Mindfulness Program (PIM) on academic students on mindfulness, emotional regulation, depression, anxiety, stress, life satisfaction, optimism, positive solitude, and loneliness. A quasi-experimental research was conducted, with pre- and post-test comparative measurements in three groups: in-person (IG), synchronous online (OG), and passive control (CG). A diverse group of students (n = 150; mean age = 25.4 ± 8.31) participated from two universities in Portugal. When compared to the CG, both active groups (IG and OG) demonstrated a beneficial interaction effect in acceptance, positive solitude, optimism, and mindfulness. The IG demonstrated a positive interaction effect in awareness and satisfaction with life, whereas the OG indicated a favorable interaction effect in impulse. When analyzing the intra-group effects, both active groups presented a significant improvement in stress, emotion regulation, mindfulness, positive solitude, and optimism. The OG demonstrated an improvement in awareness and loneliness. The main limitations of this research are that students were not randomly assigned, and groups were heterogeneous in nationality, education level, and sex. Nonetheless, PIM has indicated beneficial results in both IG and OG, and is a promising intervention for the prevention of mental health issues (e.g., stress, difficulties in emotional regulation, and loneliness), as well as for the promotion of well-being (e.g., positive solitude, mindfulness, life satisfaction, and optimism).
- Bioplastics for food packaging: environmental impact, trends and regulatory aspectsPublication . Cruz, Rui; Krauter, Victoria; Krauter, Simon; Agriopoulou, Sofia; Weinrich, Ramona; Herbes, Carsten; Scholten, Philip B. V.; Uysal-Unalan, Ilke; Sogut, Ece; Kopacic, Samir; Lahti, Johanna; Rutkaite, Ramune; Varzakas, TheodorosThe demand to develop and produce eco-friendly alternatives for food packaging is increasing. The huge negative impact that the disposal of so-called “single-use plastics” has on the environment is propelling the market to search for new solutions, and requires initiatives to drive faster responses from the scientific community, the industry, and governmental bodies for the adoption and implementation of new materials. Bioplastics are an alternative group of materials that are partly or entirely produced from renewable sources. Some bioplastics are biodegradable or even compostable under the right conditions. This review presents the different properties of these materials, mechanisms of biodegradation, and their environmental impact, but also presents a holistic overview of the most important bioplastics available in the market and their potential application for food packaging, consumer perception of the bioplastics, regulatory aspects, and future challenges.
