He encontrado que alguna farmacia puede tener existencias limitadas de ciertos medicamentos, mientras que otras pueden tener casi cualquier formato que se le ocurra y el habitual de dosis habitualidad apareció. En resumen, siempre se contiene el almacén de corroborar. Al mismo tiempo que el producto que más que gustaba ha resultado no estaba disponible en stock otro distinto por las Buenas costumbres también debe buscarse jefe no asн parezca. Por eso es importante disponer de un Plan B para actuar cuandod ello no ocurra. Ventaja de tomar un genérico en lugar de Asix Un genérico es más barato que el nombre de marca Uno de los mayores incentivos para someterse al Dónde comprar Lasix genérico en lugar de pagar la marca es que usted puede obtener un ahorrando importantes Lasix genérico. Por lo tanto, un Lasix genérico es en general mucho más barato que el homólogo de marca, así que una denominación genérica se hace posible para las personas que usan este medicamento con frecuencia. Un ejemplo: La compra de lurosemida en lugar de Lasix es una considerable ahorro para el presupuesto mensual de medicamentos.

INTERACTIVE INFORMATION RETRIEVAL
AS MULTITASKING: AN EXPLORATORY
FRAMEWORK
Amanda Spink & Minsoo ParkUniversity of Pittsburgh Interactive Information Retrieval
z How is interactive IR constructed by humans? z Interactive IR is a complex process of coordinating and interplay of various tasks, including information tasks and interactive tasks z Interactive IR within a multitasking framework z What do we already know about multitasking behavior? Multitasking Behavior
Interactive IR in the broader interdisciplinary context: cognitive psychology, human factors Multitasking is the ability of humans to handle the demands of multiple tasks by task switching Dual tasking is the human ability to simultaneously handle the demands of multiple tasks simultaneously, e.g., talking while driving Multitasking researchers: Just, et al (2001), Rubenstein, et al (2001), Wickens (1992) Interactive IR as a Multitasking Behavior
z Interactive IR is a multitasking process on two levels: information z Level 1: Multitasking information behavior z Level 2: Interactive/search task interplay Level 1: Multitasking Information Behaviors
z Interactive IR embedded within human information behavior z Humans translate of their information problems into a coherent z Humans are often engaged in multiple information problem z Humans switch between different or related information problems Multitasking Information Behavior or
Information Task Switching
z Humans are often search for information on more than one topic z Information tasks may be related or distinct, e.g., (1) gardening & z Information task switching by library users – Spink (JDoc 2004)z Information task switching and interplay between information and non-information task switching - Spink & Park (forthcoming) z Studies show multitasking by IR system and Web users – Spink, Ozmutlu & Ozmutlu (2002), Ozmutlu, Ozmultu & Spink (2003a, b) z Studies with Excite, AlltheWeb.com, Alta Vista and Vivisimo Web query data - Spink & Jansen (in press) Information Seeking and

z Embeds interactive IR research within the broader framework of z In the broader research context, multitasking is considered a common behavior, but counter-productive. z However, interactive IR context is constructed as a process of coordinated task switching on different levels z Therefore, interactive IR is only achieved through multitasking at Further Research
z Currently conducting studies to investigate: z Degree and patterns of interactive IR task switching z How users construct and coordinate their multitasking behaviors z Relation to information seeking stage, domain knowledge, gender QUESTIONS??
