International perspectives on couple relationship education
This article introduces the special section on international perspectives on couple relationship education. We first describe the theory and research underlying the increased interest in relationship education, with a strong emphasis on social policy issues. We include a discussion of both the benefits and controversies resulting from governments being involved in promoting healthy relationships. We then provide an overview of the four articles included in the special section and show how they illustrate trends occurring in a diverse set of cultural and national contexts. We conclude by highlighting issues and future directions for the relationship education field
Sensibilidade do capim-capivara a herbicidas Sensitivity of West Indian Marsh Grass to herbicides
Dois experimentos foram conduzidos em casa de vegetação com o objetivo de identificar, atravĂ©s de curvas de dose-resposta, a sensibilidade de plantas jovens e perenizadas de capim-capivara a doses crescentes (0, 25, 50, 75, 100, 125, 150, 175 e 200% da dose recomendada para gramĂneas perenes) de cyhalofop-butyl (315 g i.a. ha-1), imazapic + imazapyr (24,5 g e.a. ha-1 + 73,5 g e.a. ha-1), glyphosate (2.160 g e.a. ha-1) e amĂŽnio glufosinate (900 g i.a. ha-1). O experimento 1 foi conduzido de janeiro a março de 2010, e o experimento 2, de janeiro de 2010 a janeiro de 2011. Plantas jovens apresentaram maior sensibilidade aos herbicidas amĂŽnio glufosinate e cyhalofop-butyl, entretanto, a morte das plantas ocorreu somente quando tratadas com glyphosate e a mistura formulada de imazapic + imazapyr. Em plantas perenizadas, os herbicidas nĂŁo proporcionaram controle satisfatĂłrio.<br>Two experiments were conducted under greenhouse conditions to identify, based on dose-response curves, the sensitivity of young and perennial plants of West Indian Marsh grass to increasing doses (0, 25, 50, 75, 100, 125, 150, 175 and 200% of the recommended dose for perennial grasses) of cyhalofop butyl (315gc.p. ha-1), imazapic + imazapyr (24.5gc.p. ha-1 + 73.5gc.p. ha-1), glyphosate (2,160gc.p. ha-1) and ammonium glufosinate (900gc.p. ha-1). Experiment I was conducted from January to March 2010 and Experiment II, from January 2010 to January 2011. Young plants showed higher sensitivity to ammonium glufosinate and cyhalofop butyl; however, death occurred only when the plants were treated with glyphosate and a formulated mixture of Imazapic + Imazapyr. The herbicides did not provide satisfactory control against the perennial plants
