The relationship between board’s diversity and the reputation of integrated reports

The integrated reporting arises as an answer to the insufficiency of traditional financial report and the emergent need to disclose non-financial information to stakeholders, and it is proposed by the International Integrated Reporting Council. Given the influence of corporate governance on corporate disclosure and the key role of the companies’ board of directors in managing the disclosure of a wide range of information, the present study aims to analyze how some corporate governance characteristics may influence the reputation of integrated reports, distinguishing between reference reports and regular reports. The sample of this study comprises 374 reporters extracted from the IIRC Examples Database. The results show that the size and the experience of the board of directors does not influence the reputation of the integrated reports. In turn, the independence of the board and gender diversity influence positively the reputation of integrated reports, while role duality seems to influence negatively.info:eu-repo/semantics/publishedVersio

Resumo

Strategies for achieving sustainable logging rate in the Brazilian Amazon Forest.

Data of increment of the remnant trees after logging, ingrowth and mortality was obtained by assessment before logging and after 6 years, two sites of 50 ha, in Amazon forest. Logging scenarios were simulated to identify the logging rate potential for each studying sites, by diameter class projection method. The cy- cle of 35 years and the logging rate of 30 m3?ha?1 exceed the time required for recovery in the primary forest, in the studied site. The simulation showed that in the studying area, a well-planned logging, with minimum logging damage would be possible to implement an initial cycle of 25 years to the forest to re- cover 30 m3?ha?1, if 50% of the timber stock were reserved. The forest increment, beyond important fac- tors such as the increase of individual species, is quite dependent on the remnant trees

Confluent Orthogonal Drawings of Syntax Diagrams

We provide a pipeline for generating syntax diagrams (also called railroad diagrams) from context free grammars. Syntax diagrams are a graphical representation of a context free language, which we formalize abstractly as a set of mutually recursive nondeterministic finite automata and draw by combining elements from the confluent drawing, layered drawing, and smooth orthogonal drawing styles. Within our pipeline we introduce several heuristics that modify the grammar but preserve the language, improving the aesthetics of the final drawing.Comment: GD 201

Tolerância do feijoeiro a herbicidas aplicados na cultura da cana-de-açúcar.

O trabalho teve como objetivo avaliar a seletividade dos principais herbicidas utilizados na cultura da cana-de-açúcar, aplicados em pré ou pós-emergência, ao feijão-comum (Grupo Jalo ? cultivar Jalo Precoce). Na modalidade de pré-emergência os tratamentos avaliados foram: ametryn (2.500 g ha-1), tebuthiuron (800 g ha-1), [hexazinone + diuron] (237,6 + 842,4 g ha-1), metribuzin (1.440 g ha-1), clomazone (800 g ha-1), isoxaflutole (112,5 g ha-1), sulfentrazone (600 g ha-1), imazapic (105 g ha-1), trifluralin (1.800 g ha-1) e S-metolachlor (1.920 g ha-1), mais uma testemunha sem aplicação. Já na modalidade de pós-emergência os tratamentos foram: MSMA (1.440 g ha-1), MSMA + diuron (1.080 + 420 g ha-1), [hexazinone + diuron] (237,6 + 842,4 g ha-1), metribuzin (1.440 g ha-1), ametryn (1.500 g ha-1), [ametryn + trifloxysulfuron sodium] (1.280 + 32,4 g ha-1), halosulfuron (112,5 g ha-1), 2,4-D (1.005 g ha-1) e mesotrione (120 g ha-1), mais uma testemunha sem aplicação. Foram avaliadas a fitointoxicação, estande e altura de plantas, matéria verde e seca da parte aérea, número de plantas na colheita, altura de inserção da primeira vagem, além da produtividade. Os herbicidas S-metolachlor, tebuthiuron, trifluralin e clomazone apresentaram seletividade satisfatória às plantas de feijão cv. Jalo Precoce, quando aplicados em pré-emergência. No entanto, ametryn, [hexazinone + diuron], metribuzin, isoxaflutole, sulfentrazone e imazapic não foram seletivos, também em aplicações de préemergência. Nenhum dos herbicidas avaliados apresentou condições de seletividade para ser utilizado em pós-emergência em um sistema de cultivo integrado de feijão (cv. Jalo Precoce) em áreas de produção de cana-de-açúcar. Common bean tolerance to herbicides applied in sugarcane crop. This work was aimed to evaluate the selectivity of main herbicides used in sugar cane crop applied in pre or post emergence conditions to common bean (?Jalo? Group ? cultivar ?Jalo Precoce?). In pre emergence modality the treatments evaluated consisted of: ametryn (2.500 g ha-1), tebuthiuron (800 g ha-1), [hexazinone + diuron] (237.6 + 842.4 g ha-1), metribuzin (1,440 g ha-1), clomazone (800 g ha-1), isoxaflutole (112.5 g ha-1), sulfentrazone (600 g ha-1), imazapic (105 g ha-1), trifluralin (1,800 g ha-1), S-metolachlor (1,920 g ha-1), and a check without herbicide application. In post emergence modality treatments evaluated were: MSMA (1,440 g ha-1), MSMA + diuron (1,080 + 420 g ha-1), [hexazinone + diuron] (237.6 + 842.4 g ha-1), metribuzin, (1,440 g ha-1), ametryn (1,500 g ha-1), [ametryn + trifloxysulfuron sodium] (1,280 + 32.4 g ha-1), halosulfuron (112.5 g ha-1), 2.4-D (1,005 g ha-1) and mesotrione (120 g ha-1) besides a check without herbicide application. Phytointoxication, stand, plant height, wet and dry matter of shoots, number of plants at harvest, height of first pod insertion, and grain yield were evaluated. S-metolachlor, tebuthiuron, trifluralin and clomazone herbicides showed satisfactory selectivity to bean plants cv. Jalo Precoce, when applied in pre-emergence. However, ametryn [hexazinone + diuron], metribuzin, isoxaflutole, sulfentrazone and imazapic were not selective, even in preemergence applications. None of tested herbicides showed selectivity conditions for being used in post-emergence in one bean integrated cultivation system (cv. Jalo Precoce) in areas with sugar cane crop production

Seletividade de herbicidas registrados para uso em pré e pós-emergência na cultura da cana-de-açúcar ao feijoeiro-comum.

RESUMO: O trabalho teve como objetivo avaliar a seletividade dos principais herbicidas registrados para uso na cultura da cana-de-açúcar, aplicados em pré ou pós-emergência, ao feijoeiro-comum (cultivar Pérola). Na modalidade de pré-emergência os herbicidas avaliados foram: ametryn (2.500 g ha-1), tebuthiuron (800 g ha-1), [hexazinone + diuron] (237,6 + 842,4 g ha-1), metribuzin (1.440 g ha-1), clomazone (800 g ha-1), isoxaflutole (112,5 g ha-1), sulfentrazone (600 g ha-1), imazapic (105 g ha-1), trifluralin (1.800 g ha-1) e s-metolachlor (1.920 g ha-1), mais uma testemunha sem aplicação. Já na modalidade de pós-emergência os tratamentos foram: MSMA (1.440 g ha-1), MSMA + diuron (1.080 + 420 g ha-1), [hexazinone + diuron] (237,6 + 842,4 g ha-1), metribuzin (1.440 g ha-1), ametryn (1.500 g ha-1), [ametryn + trifloxysulfuron sodium] (1.280 + 32,4 g ha-1), halosulfuron (112,5 g ha-1), 2,4-D (1.005 g ha-1) e mesotrione (120 g ha-1), mais uma testemunha. Foram avaliadas a fitointoxicação, estande de plantas, altura de plantas, matéria verde e seca da parte aérea, número de plantas na colheita, altura de inserção da primeira vagem e produtividade de grãos. Observou-se que nenhum herbicida avaliado é seletivo ao feijão, nas aplicações em pré ou pós-emergência, pois todos reduzem significativamente a produtividade de grãos. ABSTRACT: Selectivity of pre and postemergence herbicides registered for use in sugarcane to common beans. This work was aimed at evaluating the selectivity of main herbicides registered for use in sugar cane at pre or postemergence applied at beans (?Carioca? Group ? cultivar ?Pérola?). At preemergence treatments evaluated consisted of: ametryn (2,500 g ha-1), tebuthiuron (800 g ha-1), [hexazinone + diuron] (237.6 + 842.4 g ha-1), metribuzin (1,440 g ha-1), clomazone (800 g ha-1), isoxaflutole (112.5 g ha-1), sulfentrazone (600 g ha-1), imazapic (105 g ha-1), trifluralin (1,800 g ha-1), S-metolachlor (1,920 g ha-1), and a check without herbicide application. At postemergence treatments evaluated were: MSMA (1,440 g ha-1), MSMA + diuron (1,080 + 420 g ha-1), [hexazinone + diuron] (237.6 + 842.4 g ha-1), metribuzin (1,440 g ha-1), ametryn (1,500 g ha-1), [ametryn + trifloxysulfuron sodium] (1,280 + 32.4 g ha-1), halosulfuron (112.5 g ha-1), 2.4-D (1,005 g ha-1), mesotrione (120 g ha-1), as wells as a check without herbicide application. Phytointoxication, plant stand, plant height, green and dry matter of shoots, number of plants at harvest, height of first pod insertion, and grain yield were evaluated. No herbicide analyzed is selective to beans, at pre or postemergence applications once they significantly reduce grain yield
