Fighting Carbon with Fire

This video brief and article complements the on-going Indigenous Peoples Climate Change Assessment. It forms part of the work of the UNU-IAS Traditional Knowledge Initiative. The UNU would like to thank Warddeken Land Management Ltd. and the Research School of Humanities at Australian National University for their support for this initiative.Arnhem Land - Aboriginal fire ecologist, Dean Yibarbuk, explains how traditional fire management practices have kept the country healthy for thousands of years. Recently, his mob at Wardakken have been working with local scientists to adapt traditional fire management to reduce greenhouse gas emissions whilst caring for the land

Celiac disease and immigration in Northeastern Italy: the “drawn double nostalgia” of “cozonac” and “panettone” slices

Sergio Parco, Angelo Città, Fulvia Vascotto, Giorgio TamaroImmunopathology Unit, Burlo Garofolo Children's Hospital, Trieste, ItalyAbstract: Many investigators consider children's drawings to be an important test in the evaluation of stress and anxiety, but few studies have examined the reliability and validity of indicators of emotional distress in children's projective drawings. In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the “drawn double nostalgia” of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are “cozonac” (from the native country) and “panettone” (Italian cake flavor) represents a problem that will be difficult to resolve. Only some children's hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem.Keywords: drawing, nostalgia, immigration, celiac disease, food, childre

The Relationship between Leader-member exchange and Different Perceptions on Safety Climate in the Work Group

From the end of nineties leader \u2013 member exchange theory has been considered one of the most useful approaches for studying links between leadership and organizational outcomes and particularly with safety outcomes (Zohar, 2002; Hofmann and Morgenson, 1999). The studies of Zohar and Hofmann & Morgenson suggested to integrate leadership, and in particular leader \u2013 member exchange, and safety climate (SC) as crucial factors of occupational safety. In this study leadership style is connected with the organizational-level safety climate (OSC), i.e. shared perceptions about management priorities about safety, and with group-level safety climate, considering group\u2019s supervisor as a climate agent (supervisor safety climate, SSC), i.e. shared perceptions about supervisor\u2019s priorities about safety. OSC and SSC are considered from two different points of view: supervisor\u2019s perceptions, and his/her group members\u2019 perceptions. Agreement degree about level of OSC/SSC perceived from group members and level of OSC/SSC perceived from supervisor (i.e. his/her psychological OSC, and self-evaluation of his/her safety commitment in the case of SSC) depends on LMX level, and can mediate the effect of LMX level on safety behaviours. The aim of the present work is to study the relationship between LMX level and safety behaviours, specifically safety compliance, and the mediation role of agreement degree about OSC/SSC among supervisor and his/her group members. Data collection involved 508 blue-collars belonging to 3 Italian manufacturing companies. Safety climate was measured at the organizational level (OSC) and at the group level (SSC). The same measures were gathered also on their supervisors (22 team managers). The agreement degree was computed as the difference between supervisors' and their workers' scores. Results confirmed the hypothesis of the relationship between LMX scores and safety compliance: the higher the LMX scores, the higher the safety compliance. Furthermore, the mediation role of agreement degree has been verified showing a total mediation. This means that the impact of LMX on safety compliance depends on the distance between supervisor's and his/her members\u2019 perceptions about the real importance of safety, at the organizational and at the group level. An important implication of this result is that organizations should develop effective exchange relationships between supervisor and work group, to improve safety at work

The impact of supervisor's safety profile on worker\u2019s safety performance

Safety climate (SC) has been one of the most frequently studied antecedents of safety performance since nineties. Many studies highlight the importance to analyse safety climate at group level but at group level no studies tried to compare the impact of the agreement degree about safety climate between supervisor and his group on workers' safety performance.Safety climate and safety outcomes were measured on a sample of 868 blue-collars of 11 Italian manufacturing companies. SC was measured at the organizational (OSC) and the group level. Group level SC consisted of two measures, one related to the supervisor (SSC) and one related to the co-workers in the work-group (CSC). The same measures were gathered also on 40 supervisors of each work-group (SSC consisted in a self-evaluation). A cluster analysis was conducted on supervisors, considering their perceptions about OSC, SSC and CSC, and four profiles were identified: the Judge (low OSC and CSC scores, and high SSC scores); the Easy-going (high scores for all the scales); the Pro-management (higher OSC scores, similar but lower SSC scores and low CSC scores); the Realist (similar medium size OSC, SSC and CSC scores). A significant relation was found between supervisor profile and safety outcomes, i.e. safety behaviour (compliance and participation). One-way ANOVA, with profile as the independent variable and behaviours as the dependent variable, showed higher values of safety participation for workers with a Realist supervisor. The lowest safety participation values were found for workers with Easy-going supervisor
