Individual and collective problem-solving in a foraging context in the leaf-cutting ant Atta colombica

In this paper we investigate the flexibility of foraging behavior in the leaf-cutting ant Atta colombica, both at the individual and collective levels, following a change in the physical properties of their environment. We studied in laboratory conditions the changes occurring in foraging behavior when a height constraint was placed 1 cm above part of the trail linking the nest to the foraging area. We found that the size and shape of the fragments of foraging material brought back to the nest were significantly modified when the constraint was placed on the trail: independent of their size, forager ants cut smaller and rounder fragments in the presence of a height constraint than in its absence. This size adjustment does not require any direct sensory feedback because it occurred when the ants cut fragments in the foraging area; no further cutting was done when they encountered the constraint. This points to the existence of a template that ants store and use as a reference to adjust their reach while cutting. Remarkably, despite the decrease in the foraging material brought to the nest per capita the colony was still able to improve its foraging performance by doubling the number of transporters. This study illustrates the flexibility of foraging behavior exhibited by an ant colony. It provides a rare example of insects finding an intelligent solution to a problem occurring in a foraging context, at both the individual and collective levels.     

"What if…": The Use of Conceptual Simulations in Scientific Reasoning

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called "what if" reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models.     

The associations between insecure attachment,rooming‐in,and postpartum depression: A 2 months’ longitudinal study

Postpartum depression (PPD) is the most common complication of childbearing, and recent studies have attempted to examine risk factors associated with it. The main study hypothesis was that a protective situational factor at a sensitive time period (full rooming‐in postpartum) would moderate the associations between insecure attachment dimensions and PPD. Three hundred twelve women, in either full or partial rooming‐in, participated in a longitudinal study at the maternity ward of a tertiary healthcare center. A Demographic questionnaire and the Experiences in Close Relationships Scale were administered at 1–4 days postpartum, and the Edinburgh Postnatal Depression scale at 2 months postpartum. PPD was significantly associated with both anxious and avoidant attachment dimensions, but not with rooming‐in conditions. In addition, women in partial rooming‐in showed a positive correlation between insecure attachment dimensions and PPD, whereas no such correlation was found for full rooming‐in women. A situational factor such as full rooming‐in, which occurs at a critical time point for the mother–infant relationship, can moderate the association between maternal avoidant or anxious attachment dimensions and the mother's PPD levels. Postpartum practices, such as rooming‐in, can be personalized and thus beneficial in moderating personal risk factors for PPD.     

Third party assisted conception: an African perspective

The central importance of reproduction in all human cultures has given rise to many methods and techniques of assisting reproduction or overcoming infertility. Such methods and techniques have achieved spectacular successes in the Western world, where processes like in vitro fertilization (IVF) constitute a remarkable breakthrough. In this paper, the author attempts to reflect critically on assisted reproduction technologies (ART) from the background and perspective of African culture, a culture within which human reproduction is given the highest priority but which also exhibits a highly ambivalent attitude to modern technology-assisted methods of reproduction. The author considers the ethical crux of reproductive technologies to be linked to the issue of the moral status of the human embryo and argues that a morally significant line of demarcation cannot be drawn between embryos and other categories of humans.     

Beyond the Couple: A Qualitative Analysis of Successful In‐law Relationships in Iran

In‐laws can play a significant role in the success or failure of marriages around the world. In the Middle East, recent quantitative research indicates that having trouble with in‐laws is a major predictor of divorce in Iran. To explore this further, we undertook a qualitative (grounded theory) analysis of in‐depth interviews with 17 Iranian daughters‐in‐law, five sons‐in‐law, three mothers‐in‐law, three fathers‐in‐law, and three expert family clinicians. Emergent concepts, themes, and coding categories were consistent with a Family Triad Model (FTM) of successful marital and in‐law relationships, wherein each spouse must (a) form we‐ness with their partner, (b) establish flexible boundaries between themselves and their families of origin, and (c) join their in‐laws. A higher‐order core category suggested that optimal couple and family functioning depends on the coherence or balance of these functions across the triadic role components of spouse, child‐in‐law, and family‐in‐law (or family‐of‐origin). In the changing cultural context of Iran, where blood relations have traditionally held primacy over marital relations, such triadic coherence appears crucial to marital success, at least from the perspective of many women. Our FTM results also highlight the importance of taking in‐laws into account when planning educational, preventative, or clinical interventions.     

Microstructural development during transient directional solidification of a hypomonotectic Al–In alloy

Upward directional non-steady-state solidification experiments have been performed on a hypomonotectic Al–5.5?wt%In alloy. The alloy developed cellular as-solidified microstructure for tip growth rates, V _L, higher than 0.95?mm/s. The casting regions associated with V _L?<?0.95?mm/s were shown to be characterized by a microstructure formed by In droplets disseminated in the Al matrix. Tip growth rate and microstructural features, such as cell spacing and interphase spacing, have been experimentally determined. The experimental cell spacings have been compared with theoretical predictions furnished by the Hunt–Lu model. It was found that the experimental scatter lies below the minimum range of values theoretically predicted. Moreover, the experimental cell spacing evolution with V _L is characterized by a ?1.1 power law. The droplets’ interphase spacing, λ, is related to the growth rate by the Jackson–Hunt relationship (λ ² V _L?=?constant).     

Disbelief and Trust in Psychoanalysis - A Case Study

A case of unorthodox psychoanalysis with a 27-year-old woman, during the years 1994-1998 is presented. The patient, Silja, suffered from severe character neurosis with depression. She studied humanities at the University of Helsinki with poor results, because of severe inner demands of perfection. The therapy was unorthodox, because it was necessary to change the method a few times. After two years of psychoanalysis, a life-threatening crisis occurred in 1996, and I was obliged to take a more active role and even give direct advice concerning her studies. This was successful, and she could achieve her B.A., the lower university degree. The change of method was necessary to avoid suicide. In the end we could resume psychoanalysis and analyse what had happened. Suddenly in the summer of 1998 Silja's depression disappeared and her looks improved. Therapy ended in November 1998, when she was ready to try on her own. According to her both the holding and love and also the direct advice were the most important elements in her cure. After a three years' follow-up her condition had further improved, she was married, had a job and was expecting a baby.     

Controversies and Conflicts in the Institution of "Open" Psychoanalysis: Cases from the History of the Therapeia Foundation

The institution of psychoanalysis has included controversies, dissensions and expulsions at both the theoretical-methodological and personal-organizational levels. There have also been several intra- and intergroup conflicts in the history of psychoanalysis, and in constructing and patterning the future of psychoanalytic knowledge. In the context of Finnish psychoanalysis, the Therapeia Foundation (founded in 1958) met from the start with resistance from official psychiatry and also from the IPA. For example, in the mid-1960s, D. W. Winnicott, as the President of the IPA, supported the orthodox Finnish psychoanalytic study group (later to become the Finnish Psychoanalytical Society), and pronounced that the Therapeia group was too loose and was not strictly able to use the IPA-recognized designation "psychoanalytic." The Therapeia Foundation and its Training Seminar combined classical psychoanalysis and its new versions with existentialphenomenological views, anthropological medicine, research on "social pathology" and even modern theological research. On the basis of their Swiss analytic training, three Finnish psychiatrists, Martti Siirala, Kauko Kaila and Allan Johansson, organized Therapeian training to incorporate sciences and arts, and skills involving the therapeutic "carrying" of burdens. The multifacted nature of open psychoanalysis was seen to find its proper organizational expression when the Training Seminar of the Therapeia Foundation became, in 1974, a Member of the IFPS.     

Focusing on Educational Outcomes

National education goals, content standards, and national tests are the hot topics of the day in educational reform. Special services personnel eventually will be faced with these issues, and can either be part of the discussion from the beginning, or wait and have to deal with someone else's decisions. In this article, we highlight some recent national and state educational reform activities and their probable implications for students with disabilities. We explain in brief the impetus behind the thrust toward an outcomesbased approach to education, and summarize the response of the National Center on Educational Outcomes for Students with Disabilities to this push. Possible ways in which special service providers can act to influence the focus on outcomes are described.     

The therapist with her back against the wall

This clinical paper describes once weekly psychotherapy with two boys with traumatic histories. The way in which the trauma enters the consulting room and the relationship with the therapist is explored. Technical issues are discussed, particularly the understanding of the countertransference and its modulation in communication with the patient. The therapist's intense personal anxiety about failure and about management of the difficulties that arise is linked to the impact of trauma.
