An Econometric Analysis of Intergenerational Reliance on Social Assistance

This paper examines the intergenerational transmission of participation in Québec's social assistance program. The analysis takes into account two sources of intergenerational transmission: one that is due to a causal link between parents' and children's participation and one that is due to a correlation between individual or environment-specific characteristics across generations. Our data come from the records of Québec's Ministère de la Solidarité Sociale and cover 17,203 young people who were 18 years old in 1990 and whose parents were recipients of social assistance during at least one month between 1979 and 1990. Our results reveal that, on average, a one-month increase in the parental participation during the youth's pre-adult years (age 7-17) raises the youth's participation by about 0.15 month during early adulthood (age 18-21). Moreover, this impact is stronger during the early stages of childhood (age 7-9) and late adolescence (age 16-17).Dynamics of social assistance participation, Intergenerational correlation, Canadian welfare programmes

Une étude sanitaire pluriannuelle des peintures murales dans le Lot : méthodologie, bilan et perspectives

Le département du Lot compte plus de 110 ensembles de décors peints protégés parmi les monuments historiques, identifiés en tant que tels car présentant un caractère historique ou iconographique remarquable. La plupart sont datés des XVe et XVIe siècles, période de reconstruction après la guerre de Cent Ans. En 2002 le service de l’Inventaire général du patrimoine culturel initia le recensement systématique des décors peints médiévaux et modernes du département du Lot.Puis, en 2011, en collaboration avec le service patrimoine du Département, l’ouvrage Archives de pierre, les églises du Moyen Âge dans le Lot est publié et une mise en ligne des notices thématiques est faite. Cette étude se poursuit aujourd’hui car une grande partie de ce corpus présente des altérations et des problèmes de conservation, posant les questions de l’état sanitaire des édifices et de l’efficacité, voire des effets négatifs des anciennes techniques de restauration.C’est pourquoi la DRAC Occitanie et le Département du Lot ont décidé en 2018 de lancer une étude visant à dresser un fichier sanitaire pour chacun des décors identifiés. Cette étude doit permettre de disposer d’une connaissance générale de l’état de conservation physique des peintures murales protégées, afin d’une part de mesurer si des pathologies communes ou transversales peuvent être ou non identifiées, et, d’autre part, de définir des priorités d’intervention au cours des années qui suivront. Cette démarche programmée sur du long terme démarrant par un inventaire et aboutissant à une mise en place de priorités d’interventions concrètes est particulière et unique en France.The Lot department has more than 110 sets of painted decorations protected as Historic Monuments, identified as such because of their remarkable historical or iconographic character. Most of them date from the 15th and 16th centuries during a period of reconstruction after the Hundred Years War. In 2002, the French Cultural Heritage department initiated a systematic inventory of medieval and modern painted decorations in the Lot department.Then, in 2011, in partnership with the department’s heritage service, the book Archives de pierre, les églises du Moyen Âge dans le Lot was published and the thematic notes were made available online. This study continues today because a large part of this corpus presents alterations and conservation problems, raising questions about the buildings’ structural soundness as well as the effectiveness, or even the negative effects, of old restoration techniques.Consequently, in 2018 the DRAC Occitanie and the Lot department decided to launch a study aimed at drawing up a sanitary file for each of the identified decorations. This study seeks to provide general knowledge of the protected wall paintings’ states of conservation in order to measure whether or not common or transversal pathologies can be identified, and to define priorities for interventions in the years to come. This long-term approach starting with an inventory and leading to the establishment of concrete intervention priorities is particular and unique in France

Narrow-Band Imaging in Transoral Laser Surgery for Early Glottic Cancer:A Randomized Controlled Trial

Objective: Assessing whether the additional use of narrow-band imaging (NBI) in transoral laser surgery (TOLS) for early laryngeal cancer improves clinical outcomes. Study Design: Randomized controlled trial, performed between September 2015 and November 2022. Setting: A tertiary referral hospital in The Netherlands. Methods: TOLS was carried out in 113 patients. The procedure was performed with white light imaging (WLI, n = 56) alone, or combined with NBI (n = 57). Patients received frequent follow-up laryngoscopy. Resection margin status, recurrence rate, and recurrence-free survival at 12 months, 18 months, and after study termination (maximum 86 months) were analyzed. Results: Thirty-one cases in the WLI group had a positive resection margin, versus 16 in the NBI group (p =.002). After 12 months, the recurrence-free survival was 92%: 87% for WLI versus 96% for NBI, p =.07. The recurrence rate was 7/56 (13%) for WLI, versus 2/57 (4%) for NBI, p =.09. After 18 months, the recurrence-free survival was 84% for WLI versus 96% for NBI, p =.02. The recurrence rate was 9/56 (16%) for WLI, versus 2/57 (4%) for NBI, p =.02. After study termination, the recurrence-free survival was 71% for WLI versus 83% for the NBI group (p =.08). The recurrence rate was 16/56 for WLI, versus 10/57 for NBI (p =.16). Conclusion: The additional use of NBI during TOLS significantly decreased the number of positive resection margins. Although not statistically significant at all time points, patients treated with NBI-supported TOLS showed a lower recurrence rate and better recurrence-free survival. Further studies in larger patient groups are needed to confirm these results.</p

Evaluating Laryngopharyngeal Tumor Extension Using Narrow Band Imaging Versus Conventional White Light Imaging

OBJECTIVE/HYPOTHESIS: Comparing detection and extension of malignant tumors by flexible laryngoscopy in the outpatient setting with laryngoscopy under general anesthesia using both White Light Imaging (WLI) and Narrow Band Imaging (NBI). STUDY DESIGN: Prospective randomized controlled trial. METHODS: Two hundred and thirty-three patients with laryngeal and pharyngeal lesions underwent flexible and rigid laryngoscopy, with both WLI and NBI. Extension of malignant lesions (n = 132) was compared between both techniques in detail. RESULTS: Sensitivity of NBI during flexible endoscopy (92%), was comparable with that of WLI during rigid endoscopy (91%). The correlation of tumor extension between flexible and rigid laryngoscopy was high (rs = 0.852-0.893). The observed tumor extension was significantly larger when using NBI in both settings. The use of NBI during flexible laryngoscopy leads to upstaging (12%) and downstaging (2%) of the T classification. CONCLUSIONS: NBI during flexible laryngoscopy could be an alternative to WLI rigid endoscopy. NBI improves visualization of tumor extension and accuracy of T staging.
