Este artículo realiza un acercamiento a Orlando, de Virginia Woolf, y a Agua viva, de Clarice Lispector, como obras que logran escribir la multiplicidad, la fluidez y la contingencia del ser. Jugando con las convenciones de la biografía y la autobiografía respectivamente, estas obras encuentran los medios para presentar un sujeto multidimensional y para mostrar, en particular, cómo la dimensión relacional, forjada por un orden simbólico patriarcal, ha hecho de la mujer el “otro" del hombre; un “otro" que debe ser dominado. Se exploran en este artículo los conceptos de “economía masculina" y “economía femenina" teorizados por Hélène Cixous y se propone al lenguaje poético como un medio capaz de eludir los dictados del falocentrismo. Lo poético, que no puede ser nunca agotado por uno o varios sistemas de significación, brinda la posibilidad de ir más allá de las categorizaciones y de explorar la multiplicidad. Tanto Orlando como Agua viva muestran las estrategias y las esperanzas de personajes y escritoras que ven en el lenguaje poético, en la “escritura femenina" como la entiende Cixous, el potencial de desarticular la “economía masculina" y abrir un nuevo espacio para sujetos diversos, múltiples y complejos.

This paper will document financial aspects of transactions, and trade credit supply behavior with FDI among small and medium-sized enterprises(SMEs) based on two original surveys, conducted in four cities in China in 2003. The survey was designed to capture the nature of inter-firm transactions, trade credit and other financial conditions. Literature on FDI mainly refers to technology transfer, employment or investment. This paper focuses on the role and significance of FDI in the supply of trade credit due to its trade credit enforcement technology. Yanagawa, Ito and Watanabe [2006] developed a model which indicates that when a seller has higher enforcement technology or a buyer has richer liquidity, both trade credit and transaction volume will be increased. In this paper, we confirmed that FDI and G contributed to the provision of trade credit and had a positive external effect on trade credit enforcement towards China’s economy. (1) Sales towards FDI customers have the power to increase the trade credit ratio,even when controlling other factors such as choice of payment instrument, competitiveness, and expost default management. This implies that FDI does provide trade credit, not only because it has superior liquidity, but because it is also superior in terms of enforcement of trade credit repayment.(2) Cash constraints of the buyer influence the decisions concerning trade credit provided by the seller, as a model in Yanagawa, et al. [2006] predicted, and this implies that strategic default is a serious concern among SMEs in China. (3) Spillover effect exists in payment enforcement technology in transactions with FDI customers.

DNA-strand exchange promoted by Escherichia coli RecA protein normally requires the presence of ATP and is accompanied by ATP hydrolysis, thereby implying a need for ATP hydrolysis. Previously, ATP hydrolysis was shown not to be required; here we demonstrate furthermore that a nucleoside triphosphate cofactor is not required for DNA-strand exchange. A gratuitous allosteric effector consisting of the noncovalent complex of ADP and aluminum fluoride, ADP.AIF4-, can both induce the high-affinity DNA-binding state of RecA protein and support the homologous pairing and exchange of up to 800-900 bp of DNA. These results demonstrate that induction of the functionally active, high-affinity DNA-binding state of RecA protein is needed for RecA protein-promoted DNA-strand exchange and that there is no requirement for a high-energy nucleotide cofactor for the exchange of DNA strands. Consequently, the free energy needed to activate the DNA substrates for DNA-strand exchange is not derived from ATP hydrolysis. Instead, the needed free energy is derived from ligand binding and is transduced to the DNA via the associated ligand-induced structural transitions of the RecA protein-DNA complex; ATP hydrolysis simply destroys the effector ligand. This concept has general applicability to the mechanism of energy transduction by proteins.

This article studies the services exchanged in a particular Spanish time bank. Using data from users and transactions, we analyse the users’ profile as well as the determinants of providing and receiving different services. Our results show that the representative user is a Spanish female, not married, middle aged, highly educated and unemployed. We also find differences in the personal characteristics driving the supply and demand of services.
