Intersensory Redundancy Enhances Memory in Bobwhite Quail Embryos

Information presented concurrently and redundantly to 2 or more senses (intersensory redundancy) has been shown to recruit attention and promote perceptual learning of amodal stimulus properties in animal embryos and human infants. This study examined whether the facilitative effect of intersensory redundancy also extends to the domain of memory. We assessed bobwhite quail chicks' ability to remember and prefer an individual maternal call presented either unimodally or redundantly and synchronously with patterned light during the period prior to hatching. Embryos provided with unimodal auditory exposure failed to prefer the familiar call over a novel maternal call postnatally at 48 hr and 72 hr following exposure. In contrast, embryos provided with redundant, synchronous audiovisual stimulation significantly preferred the familiar call at 48 hr following exposure, but not at 72 hr. A second experiment provided chicks with a single 10‐min refamiliarization with the familiar call at either 48 hr or 72 hr following hatching. Chicks given only unimodal auditory exposure prior to hatching did not appear to benefit from this brief postnatal refamiliarization, showing no preference for the familiar call at either 72 or 96 hr. Chicks that received redundant audiovisual stimulation prenatally showed a significant preference for the familiar call (following the brief reexpo sure 24 hr earlier) at both 72 and 96 hr of age. These results are the first to demonstrate that redundantly specified information is remembered longer and reactivated more easily than the same information presented unimodally. These findings provide further evidence of the salience of intersensory redundancy in guiding selective attention and perceptual learning during early development.     

CALGARY FAMILY INTERVENTION MODEL: ONE WAY TO THINK ABOUT CHANGE

This article defines and describes the Calgary Family Intervention Model (CFIM). CFIM is an organizing framework conceptualizing the intersect between a particular domain (i.e., cognitive, affective, or behavioral) of family functioning and a specific intervention offered by a health professional. Examples and discussion of interventions such as storying the illness experience, encouraging respite, and asking interventive questions are presented. CFIM is one way that health professionals can conceptualize about change.     

Effects of Africentric Socialization on Psychosocial Outcomes in Black Girls: The Critical Role of Gender

African American social work scholars recommend rigorous research and evaluation of Africentric interventions as one approach to building culturally appropriate, evidence-based treatments for the Black community. Following this approach, this pilot study evaluates the Imani Rites of Passage program, a 15-week Africentric curriculum with 10 Black adolescent females (mean age = 12.40), comparing their pre- and post-intervention data to that of a no-intervention group of 13 Black males (mean age = 12.08). The program evaluation is based on the degree of correspondence between theory and the measurement model spelled out by the cognitive-cultural view of African-American identity. The findings for Black females were consistent with the cognitive-cultural model in some ways but not in others, and they were more complex than the predictions. Future Africentric interventions guided by the cognitive-cultural model must consider gender differences in the outcomes. Implications for social work research and practice are discussed.     

Culture Change in Aged-Care Facilities: A Café's Contribution to Transforming the Physical and Social Environment

Objective: To discuss the potential of a café on the premises of an aged-care facility as a vehicle for culture change. Method: Secondary analysis of primary qualitative data that explored the value of a café in an aged-care facility, compared with culture-change principles established from a literature review. Results: Secondary analysis established congruence between culture-change principles and the themes established in the primary qualitative data. A café, in one aged-care facility, has facilitated the following dimensions of culture change for residents: individualized care, facilitation of meaningful relationships, opportunities for participation in life roles, and creation of a sense of belonging. Conclusion: Culture change can be achieved through environmental innovations, such as a café, where food and dining maximize social opportunities and create a homelike environment that facilitates continuation of residents' identity.     

Young Infants Match Facial and Vocal Emotional Expressions of Other Infants

Research has demonstrated that infants recognize emotional expressions of adults in the first half year of life. We extended this research to a new domain, infant perception of the expressions of other infants. In an intermodal matching procedure, 3.5‐ and 5‐month‐old infants heard a series of infant vocal expressions (positive and negative affect) along with side‐by‐side dynamic videos in which one infant conveyed positive facial affect and another infant conveyed negative facial affect. Results demonstrated that 5‐month‐olds matched the vocal expressions with the affectively congruent facial expressions, whereas 3.5‐month‐olds showed no evidence of matching. These findings indicate that by 5 months of age, infants detect, discriminate, and match the facial and vocal affective displays of other infants. Further, because the facial and vocal expressions were portrayed by different infants and shared no face–voice synchrony, temporal, or intensity patterning, matching was likely based on detection of a more general affective valence common to the face and voice.     

Phallus or Penis: Commentary on Cornelia St. John's Paper

The Lacanian concept of the masculine and feminine as symbolic positions, which may or may not correspond to anatomy, is clinically useful in the case of Mr. M. This discussion suggests that these concerns can be addressed by the feminist Lacanian theorists (Ragland, 1995), who discuss language within the landscape of primary repression as well as secondary repression. The analyst here illustrates the insufficiency of listening or speaking from only a preoedipal/maternal or an oedipal/paternal position; both are needed. In this discussion, the factors of sexual difference, psychosexual identification, gender definitions, and object choice are described in their different relations to one another when in preoedipal land (the Law of Language) versus the oedipal territory (Law of the father/culture). In summary, it could be said that stuttering or the inability to speak one's name is an incomplete weaning–there is no “I” who speaks from a secure symbolic indentification.     

Exploring the Impact of Social Axioms on Firm Reputation: A Stakeholder Perspective

This study proposes a model of how deeply held beliefs, known as ‘social axioms, moderate the interaction between reputation, its causes and consequences with stakeholders. It contributes to the stakeholder relational field of reputation theory by explaining why the same organizational stimuli lead to different individual stakeholder responses. The study provides a shift in reputation research from organizational‐level stimuli as the root causes of stakeholder responses to exploring the interaction between individual beliefs and organizational stimuli in determining reputational consequences. Building on a conceptual model that incorporates product/service quality and social responsibility as key reputational dimensions, the authors test empirically for moderating influences, in the form of social axioms, between reputation‐related antecedents and consequences, using component‐based structural equation modelling (n = 204). In several model paths, significant differences are found between responses of individuals identified as either high or low on social cynicism, fate control and religiosity. The results suggest that stakeholder responses to reputation‐related stimuli can be systematically predicted as a function of the interactions between the deeply held beliefs of individuals and these stimuli. The authors offer recommendations on how strategic reputation management can be approached within and across stakeholder groups at a time when firms grapple with effective management of diverse stakeholder expectations.     

Evaluating risk: global fees and episodic care

In 1999, two articles in The Physician Executive -- "Part I: Global Theory and the Nature of Risk (July-August)." and "Part II: Towards a Choice-Based Model of Managed Care (October-November)" -- outlined the flaws of orthodox managed care theory and highlighted the unique advantages of moving to a genuinely market-based model, which included the concept of direct contracting for integrated episodes of care. This follow-up focuses on comparing an episode contracting system to a traditional capitated program and outlines the features that make this approach much more attractive to physicians, payers, and most importantly patients.     

Attributes of Successful and Unsuccessful Acquisitions of US Firms

Acquisitive growth strategies continue to be popular, in spite of increasing evidence that they often do not enhance the financial performance of acquiring firms and may adversely affect innovation. However, some acquisitions are associated with both increases in financial performance and a strengthened commitment to R&D while others experience decreases in both. Multiple theories have been offered to explain acquisitions and their outcomes, but few have received strong empirical support. This paper describes a multiple rater, multiple-case study of acquisitions that had highly favourable outcomes and others that experienced highly unfavourable outcomes. All twelve of the high performing acquisitions studied were found to exhibit the dual characteristics of friendliness during acquisition negotiations and resource complementarities between the two firms. Additionally, debt played an important role in the success (low to moderate debt) or lack of success (high or extraordinary debt) in 21 of the 24 acquisitions studied. Inadequate target evaluation was a factor in 11 of the 12 acquisitions with low performance. Importantly, the results of both sets of acquisitions suggested that a configuration of attributes affected post-acquisition performance. Other findings both supported and contradicted commonly held beliefs about acquisitions, as well as highlighted variables not typically associated with acquisition strategies. The study provides directions for future theory development and empirical research on acquisitions.
