Yes, we can (but for different reasons): Collective narcissism is linked to different values but similar pro-ingroup collective action tendencies among disadvantaged and advantaged ethnic groups.

Collective narcissism, a belief that one's group is exceptional and entitled to special treatment but underappreciated by others, is related to important social and political outcomes but has been predominantly studied in advantaged groups. The present research compares the motivational correlates (through values) of collective narcissism in ethnic groups of different status (advantaged and disadvantaged) and explores its associations with attitudes towards, and intention to engage in collective action. Three studies examined these processes in different national and intergroup contexts (total N = 16,275). Overall, ethnic collective narcissism was linked to self-protective values (power, and less consistently, conservation) in advantaged groups but to universalism in disadvantaged groups. Moreover, in both advantaged and disadvantaged groups, ethnic collective narcissism was related to more positive attitudes towards, and intentions of pro-ingroup actions but not to attitudes towards (other) disadvantaged groups (i.e., intergroup solidarity). These studies suggest that collective narcissism may be associated with different motivations, yet linked to similar intergroup attitudes among advantaged and disadvantaged groups.

Addressing climate change with behavioral science: A global intervention tournament in 63 countries.

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Comparison of sacroiliac screw techniques for unstable sacroiliac joint disruptions: a finite element model analysis.

Vertically unstable pelvic injuries associated with sacroiliac disruption are challenging. Although percutaneous iliosacral fixation using two screws at S1 vertebral body has been shown beneficial, the use of two transiliac screws at S1 has been proposed to increase the fixation strength of the construct. In the herein study, the finite element method (FEM) was performed to analyse the biomechanical behaviour of five different constructions using iliosacral screws only, transiliac screws only, and combining an iliosacral and a transiliac screw. A vertically unstable AO 61C1.2 type pelvic injury was produced for the evaluation of the posterior pelvic displacement and implant stress, and the anterior implant stress using FEM. The symphysis pubis was fixed with a 3.5-mm reconstruction plate in all cases. The model was axially loaded with 800N applied in the centre of S1 body, perpendicular to the ground (Y-axis), simulating the bipodal stance moment. There was a statistically significant reduction in both posterior displacement and implant stresses in the groups fixed with at least one transiliac screw compared to the groups fixed with iliosacral screws. In our FEM study, the construct using two transiliac screws in S1 is biomechanically superior for stabilizing the sacroiliac joint in vertically unstable pelvic ring injuries compared to the other configurations. Lateral displacement, posterior displacement, and von Mises stress were reduced with this construct. A good option can be the use of one iliosacral screw and one transiliac screw in S1.

Impacts of citrus pulp addition and wilting on elephant grass silage quality / Impacto da adição de polpa citríca e do emurchecimento na qualidade da silagem de capim-elefante

The objective of this work was to evaluate the use of citrus pulp addition and wilting on fermentative characteristics, chemical composition as well as gas and effluent losses of elephant grass silage. The elephant grass (70 growth days) was collected manually; one portion was immediately chopped and another one was allowed to wilt in the sun for a period of 6 h and subsequently chopped for the production of silage. Experimental PVC silos (10 cm diameter x 30 cm height) were used and sand bags were placed at the bottom of the silos. Citrus pulp (80 g kg-1 of MN) was added at the beginning of ensilage. The ensiled material was manually compressed to provide a specific mass of approximately 600 kg m-3 of silage. After 60 days, the silos were opened; gas and effluent losses were calculated and we determined pH, dry matter (DM), crude protein(CP), neutral detergent fibre (NDF), lignin, ammonia nitrogen, ash and in vitro dry matter digestibility (IVDMD). We added 0 or 80 g kg-1 of citrus pulp to wilted and un-wilted elephant grass. We used a completely randomised design with a 2 x 2 factorial arrangement (wilted or un-wilted) x (with or without citrus pulp), totalling treatments with five repetitions. Average values were compared using the F test with a probability of 5%. The addition of citrus pulp resulted in reduced levels of NDF, lignin, ash, N-NH3 and pH and in increased values of DM and IVDMD of silages. Wilting increased the DM, NDF and lignin values and reduced the concentrations of CP, IVDMD and N-NH3. Based on our results, citrus pulp addition improves the chemical composition of elephant grass silage and increases its in vitro dry matter digestibility.

Objetivou-se avaliar o uso de polpa cítrica e do emurchecimento sobre as características fermentativas, composição química e perdas de silagens de capim-elefante. O capim-elefante foi colhido manualmente com cerca de 70 dias de rebrota, uma parte foi picada imediatamente e outra foi emurchecida ao sol por 6 horas e posteriormente picado para confecção das silagens. Foram utilizados silos experimentais de PVC com 10 cm de diâmetro e 30 cm de altura, no fundo dos silos foram colocados sacos com areia. A polpa cítrica foi incluída na base de 80 g kg-1 da matéria natural no momento da ensilagem. O material ensilado foi compactado manualmente de forma a proporcionar massa específica de aproximadamente 600 kg m-3 de silagem. No momento da ensilagem foram pesados os silos vazios, os sacos com areia, o material ensilado e os silos cheios. Após 60 dias os silos foram pesados novamente e logo em seguida abertos. Foram calculadas as perdas por gases e efluentes e determinados o pH, conteúdo de matéria seca, teores de proteína bruta, fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), celulose, hemicelulose e lignina, cinzas, nitrogênio amoniacal e digestibilidade in vitro da matéria seca (DIVMS). Foi utilizado o delineamento inteiramente casualisado em arranjo fatorial 2 (emurchecido ou não) x 2 (com polpa cítrica ou não), 4 tratamentos com 5 repetições, totalizando 20 parcelas. As médias foram comparadas pelo teste F a 5%. O uso de polpa cítrica reduziu os níveis de FDN, lignina, cinzas, N-NH3 e o pH e aumentou a MS e a DIVMS das silagens. O emurchecimento aumentou a MS, FDN e a lignina e reduziu a proteína bruta, DIVMS e N-NH3. O uso da polpa cítrica melhora a composição química e a digestibilidade in vitro da matéria seca de silagens de capim-elefante.
