Influence of board interlocking on earnings management
ABSTRACT The participation of directors on more than one board is called “board interlocking”. This phenomenon contributes to the spread of management and governance practices, through directors sharing their knowledge and experiences on other boards. Thus, directors could “carry” the earnings management practices present in one company into another in which they sit on the board. It is assumed that the greater directors’ direct or indirect connections on boards, the greater the sharing of information, especially information that can be reflected in company earnings quality. In light of the above, the aim of this study is to verify the influence of board interlocking on earnings management in companies listed on the São Paulo Stock, Commodities, and Futures Exchange (BM&FBovespa). The study is characterized as descriptive, quantitative, and documentary, and uses a sample of companies listed on the BM&FBOVESPA between 2011 and 2013. For earnings management, the model from Kang and Sivaramakrishnan (1995) was used, while for interlocking, degree centrality measures were used for direct board member connections, and intermediation centrality for indirect connections. The results indicate that earnings management is influenced by the interlocking of board members. It is concluded that the greater the degree centrality, the greater positive earnings management is, and that variations in positive and negative accruals are influenced by board member intermediation. The results reinforce the idea that earnings management behavior can be transferred between companies by the directors that make up their boards
Indicadores bioquĂmicos e hormonais de casos naturais de toxemia da prenhez em ovelhas
Toxemia da prenhez Ă© considerada um transtorno metabĂłlico de grande impacto econĂ´mico na produção de ovinos, porĂ©m as particularidades de repercussĂŁo sistĂŞmicas deste distĂşrbio ainda sĂŁo pouco esclarecedoras. O presente estudo teve por objetivo avaliar o perfil bioquĂmico e hormonal de 77 ovelhas com diagnĂłstico clĂnico de toxemia da penhez e comparar os achados laboratoriais de acordo com a resolução clĂnica dos animais, alta hospitalar (G1) e aqueles que morreram (G2). A manifestação clinica da doença foi observada no perĂodo do prĂ©-parto em 100% dos animais, destes 66,2 % (n=51) receberam alta clĂnica e 33,8% (n=26) morreram. Dos casos de toxemia da prenhez estudados havia gestação mĂşltipla em 55,8%. Dentre os parâmetros estudados, cortisol, urĂ©ia, AST e CK estavam mais elevados no G2 em relação ao G1 com diferenças significativas (P<0,05). Foi encontrado aumento nas concentrações de glicose plasmática, frutosamina, albumina, creatinina, Ăź-hidroxubutirato, ácido graxo nĂŁo esterificado e L-lactato, porĂ©m nĂŁo houve diferenças entre os grupos (P>0,05). NĂŁo ocorreram alterações nas taxas de colesterol e triglicerĂdios. Houve redução nos Ăndices da insulina, nĂŁo havendo diferenças entre G1 e G2 (P>0,05). Todas as ovelhas apresentaram cetonĂşria e acidĂşria
