Attending to detail by communal spider-eating spiders

Communal predators may often need to make especially intricate foraging decisions, as a predator's success may depend on the actions of its neighbours. Here,we consider the decisions made by Portia africana, a jumping spider (Salticidae) that preys on other spiders, including Oecobius amboseli (Oecobiidae), a small prey spider that lives under small sheets of silk (nests) on the walls of buildings. P. africana juveniles settle near oecobiid nests and then ambush oecobiids as they leave or enter the nest. Two or more P. africana juveniles sometimes settle at the same nest and, when an oecobiid is captured, the P. africana juveniles may share the meal. We investigated the joining decisions made by na?ve P. africana juveniles. Experiments were based on using lures (dead spiders positioned in lifelike posture) arranged in a series of 17 different scenes defined by the presence/absence of a nest, the lure types present and the configuration of the lures and the nest. Our findings imply that P. africana juveniles make remarkably precise predatory decisions, with the variables that matter including whether a nest is present, the identity of spiders inside and outside a nest and how spiders are positioned relative to each other and the nest.     

Evaluation from the inside: Participatory evaluation of agricultural research in the Philippines

This paper discusses the experience of a Philippines-based agricultural research program, where participatory evaluation is embedded in a broader, user-centered participatory research approach. Three case projects illustrate and analyze participatory evaluation of agricultural research in a developing country context. Different evaluation types are identified and their use in different phases of the research process is discussed. These field experiences show how “evaluation from the inside” can contribute to effective research planning and implementation, particularly in enhancing sensitivity to user needs and situations. network for user participatory rootcrop R&D sponsored by the International Potato Center in Asia. Under his leadership, UPWARD has increasingly sought to build participatory monitoring and evaluation into the network’s research and development activities. He has a Ph.D. in communication and innovation studies from Wageningen Agricultural University in The Netherlands. Prior joining UPWARD, Campilan worked with the International Institute of Rural Reconstruction and the Philippine Root Crop Research and Training Center. His research interests include communication of innovations, institutional linkage development, participatory research methods and tools, and strengthening local knowledge systems. From 1991 until 1997 he was coordinator of Users’ Perspectives With Agricultural Research and Development (UPWARD) network. He was previously based in Latin America. His main research interests include the socioeconomic and cultural aspects of crop genetic diversity conservation and utilization involving ethnobotanical studies, on-farm conservation, and work on seed systems. He is also interested in research on rural enterprise development. He has been actively involved in capacity building initiatives among national agricultural researchers, especially in participatory research methods and planning techniques. He can be contacted CIP-ESEAP, Kebun Percobaan Muara, Jalan Raya Ciapus, Bogor 16610, Indonesia, fax (62 251) 316 264, e-mail: G.Prain@cgiar.org. Her major responsibilities include facilitating the network’s activities on sustainable crop management R&D and on capacity building in participatory approaches and methods. At the UPWARD coordinating office, she is in charge of training, publications, and information management. She has extensive training and hands on experience in the use of participatory methods and tools, particularly through a Philippines project on soil resource management for sweetpotato production. She has an MSc in family resource management and development communication from the University of the Philippines at Los Ba?os. Her research interests include sustainable crop management, strengthening local R&D capacity, and field testing participatory methods and tools.     

Women and Work—Rights,Realities, and Prospects

Women's place as a permanent part of the work force has been established, but the question now is whether women will continue to be the majority of low-skilled, low-paid workers or will share equally in opportunities in all fields of employment. The economic needs of most women workers are approximately the same as those of male workers. With 6.6 million women heads of families in 1973, nearly one out of three such families was poor according to Department of Labor criteria. Professional job counselors have a responsibility to support women who make nontraditional career choices. Counselors and others must also be aware of the rights and resources available to each woman in pursuing her career goals.     

Neurones miroir, résonance et cognition sociale

Mirror neurons were discovered in the 1990's by cognitive neuroscientists from Parma. How central are mirror neurons in primates, social cognition. Do mirror neurons enable an observer to match the agent's observed movements onto her own motor repertoire? Does this matching enable the observer to represent the agent's intention, as argued by Rizzolatti et al? A positive answer to these questions can't be provided unless one assumme that mirror neurons compute the goal of an action by means of a “forward model” of the perceived action. However, the experimental evidence rather suggests that mirror neurons compute the motor means for achieving the desired goal, in accordance with an “inverse model” of the perceived action.     

Knowing what we can do: actions,intentions, and the construction of phenomenal experience

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.     

“A GREATEST MIRACLE”: STANLEY CAVELL,MORAL PERFECTIONISM,AND THE ASCENT INTO THE ORDINARY

What to make of “the ordinary,”“the everyday,” and their common “eventfulness”? What to think of what Veena Das, in her recent book Life and Words, prefaced by Stanley Cavell, has called our need to “descent into the ordinary”? Is there a parallel figure of “ascent,” again, into the same “ordinary,” that we might we want to juxtapose with it and that resembles the motif of “change,” even “conversion,” that Cavell analyzes at some length in The Claim of Reason and throughout his oeuvre as a whole? And what could be our reasons for doing so? This essay will draw on Cavell's reading of Ibsen's work in the volume Cities of Words to spell out what such an “ascent” might mean.     

Consensus, clinical decision making, and unsettled cases

The model of clinical ethics consultation (CEC) defended in the ASBH Core Competencies report has gained significant traction among scholars and healthcare providers. On this model, the aim of CEC is to facilitate deliberative reflection and thereby resolve conflicts and clarify value uncertainty by invoking and pursuing a process of consensus building. It is central to the model that the facilitated consensus falls within a range of allowable options, defined by societal values: prevailing legal requirements, widely endorsed organizational policies, and professional standards of practice and codes of conduct. Moreover, the model stipulates that ethics consultants must refrain from giving substantive recommendations regarding how parties to a moral disagreement in the clinic should evaluate their options. We argue that this model of CEC is incomplete, because it wrongly assumes that what counts as the proper set of allowable options among which the parties are to deliberate will itself always be clearly discernible. We illustrate this problem with a recent case on which one of us consulted-a neonate born with trisomy 18 (T18). We try to show that law, policy, and standards of practice reveal no clear answer to the question posed by the case: namely, whether forgoing gastrostomy tube feedings for a baby with T18 is allowable. We suggest there may be other kinds of cases in which it may simply be unsettled whether a given choice falls within the set of allowable options within which consensus is to be facilitated. What should an ethicist do when confronting such unsettled cases? We agree with the facilitation model that an ethicist should remain neutral among the allowable options, when it is clear what the allowable options are. But, in unsettled cases, the role of a consultant should be expanded to include a process of moral inquiry into what the allowable options should be. We end by raising the issue of whether this means an ethicist should share his or her own conclusions or views about the allowability of a given clinical option.     

Learning as a Path,Not a Goal: Contemplative Pedagogy – Its Principles and Practices

What is contemplative pedagogy and how is it practiced in Religious Studies classrooms? Contemplative pedagogy cultivates inner awareness through first‐person investigations, often called “contemplative practices.” Contemplative teaching practices range widely: silent sitting meditation, compassion practices, walking meditation, deep listening, mindfulness, yoga, calligraphy, chant, guided meditations, nature observation, self‐inquiry, and many others. Since narrative is a mode of instruction prevalent in contemplative literature, the article includes first‐hand reflections from students and a narrative account of how an initially skeptical professor came to incorporate contemplative teaching methods into her courses. It expands from the personal narratives to highlight the work of many contemplative professors in the field. These real‐life examples are put into the context of recent publications on shifts in higher education and meditation research. The article seeks to demonstrate the power of contemplative teaching to fulfill many hopes for liberal arts learning. Of particular importance is its emphasis on interior qualities of lifelong impact, such as self‐knowledge and ethical cultivation.
