Circular economy may alleviate environmental impact of holiday shopping
Cut-rate deals may be enticing around the holidays, but low prices can come with a high environmental cost. If shoppers don't make choices wisely, their purchases could end up in the landfill. The clothing industry accounts for about 10% of global carbon emissions, but some retailers are taking more responsibility for their environmental impact, said McGill Professor Javad Nasiry, Director of the Sustainable Growth Initiative, at the Desautels Faculty of Management. Zara is one company that has taken steps toward greater sustainability. In October 2022, the Spanish fast-fashion giant launched Zara Pre-owned, a repair and exchange platform that allows its customers to re-sell their Zara purchases and request repairs like replacement zippers.
Les secrets des branches d'arbres de Noël
Lors d'une promenade hivernale dans les bois, vous êtes-vous déjà demandé pourquoi les branches des arbres de Noël et autres conifères poussent comme elles le font ? Certains de ces arbres sont joufflus et courts, tandis que d'autres sont grands et maigres. À l'aide d'une modélisation statistique et d'un tomodensitomètre comme ceux utilisés dans les hôpitaux, une équipe de chercheurs de l'Université McGill, dont le professeur de sciences végétales Pierre Dutilleul, a montré pourquoi les branches d'arbres plus jeunes poussent d'une certaine façon en se basant sur les modèles de croissance des branches plus anciennes. "Nos yeux ne peuvent pas toujours voir la tige et les branches connectées d'un arbre de Noël - le scanner nous a donné accès à ce monde caché", a déclaré Dutilleul. Le scanner a également permis d'effectuer des mesures numériques qui auraient été pratiquement impossibles à réaliser autrement, a ajouté le Prof. Dutilleul, comme la distance entre les branches descendantes d'une même branche parentale, ou l'angle formé par une branche descendante par rapport à sa branche parentale. Les chercheurs ont constaté que les branches du quatrième niveau suivaient un modèle de croissance déterminé en grande partie par les modèles de ramification des branches du deuxième niveau, et non, comme ils s'y attendaient, du troisième.
Increasing vaccine uptake in one of Montreal's most culturally diverse neighbourhoods
Community-led initiatives providing linguistically and culturally tailored services in Parc-Extension, the neighbourhood with the highest population density and immigration population in Montreal, helped increase COVID-19 vaccine uptake among the neighbourhood's residents, according to a new study from McGill University researchers. Supervised by Professor Ananya Banerjee at the School of Population and Global Health and Department of Epidemiology, Biostatistics, and Occupational Health, the team. interviewed residents and identified that language barriers and inadequate government support for immigrants contributed to inaccessibility to vaccine information and other health-care services for Parc-Ex residents. The researchers say improving access to healthcare services among immigrant groups requires consideration of the non-medical factors that influence health outcomes and fostering trusting partnerships between governments and community organizations. The researchers, who worked in collaboration with Université de Montréal, Co-Vivre, and Afrique au féminin with funding from Canadian Institutes of Health Research (CIHR), conducted 50 interviews with Parc-Extension residents. Despite the neighbourhood's much lower COVID-19 vaccination rate during Quebec's first rollout, by August 2021, the neighbourhood's first dose rate surpassed Montreal's by four per cent.
Mistreated children have more difficulty with emotions as adults
McGill University researcher Rachel Langevin, Professor in the Department of Educational and Counselling Psychology, has found that emotional maltreatment in childhood is linked to difficulties understanding our own emotions, managing impulsivity, and regulating our emotions in emotionally charged situations, which can often arise around the holidays. Even though child maltreatment can take many forms, these are not often studied together. The researchers examined how different forms of child maltreatment -- including physical abuse, sexual abuse, emotional maltreatment, neglect, and exposure to domestic violence -- manifest in the emotional development of young adults. They found that young adults who suffered emotional maltreatment as children were also better at recognizing anger and fear in others but had more difficulty recognizing sadness. Sexual abuse was associated with difficulties achieving one's goals in emotionally charged situations, and neglect was associated with more difficulty managing impulsivity. Physical abuse was associated with a decreased ability to recognize fear. Survivors of child emotional maltreatment, are encouraged not to minimize what they have suffered, and treat themselves with compassion, which can be a first step toward healing.
