The Phenomenology of Rheumatology: Disability,Merleau‐Ponty,and the Fallacy of Maximal Grip

This paper charts the concepts of grip and the bodily auxiliary in Maurice Merleau‐Ponty to consider how they find expression in disability narratives. Arguing against the notion of “maximal grip” that some commentators have used to explicate intentionality in Merleau‐Ponty, I argue that grip in his texts functions instead as a compensatory effort to stave off uncertainty, lack of mastery, and ambiguity. Nearly without exception in Phenomenology of Perception, the mobilization of “grip” is a signal of impending loss, and is offered as a strategy for managing failure rather than as an example of sure‐footed mastery. I read Merleau‐Ponty alongside Mary Felstiner's Out of Joint: A Public and Private Story of Arthritis to explore these other, attenuated dimensions of grip. Finally, the paper turns to Harriet McBryde Johnson's memoir Too Late to Die Young as an example of a way of thinking disabled embodiment otherwise.     

The impact of relational demographics on perceived managerial trustworthiness: similarity or norms?

Perceived trustworthiness is a critical antecedent of interpersonal trust, yet researchers have a limited understanding of how such perceptions are generated. The authors used 2 competing perspectives within the relational demography literature--similarity-attraction and relational norms--to empirically examine the effect of demographic differences. Whereas the similarity-attraction account suggests that subordinates will perceive their managers as more trustworthy when managers and staff are similar in demographic attributes, the relational norms account proposes that subordinates will perceive their managers as more trustworthy when their demographic differences follow normative expectations. Data collected from a field study of 178 manager-subordinate dyads in Hong Kong and Macau support the relational norms account in terms of education and organizational rank. The authors discuss the theoretical and practical implications of the study.     

Carbon monoxide levels and rates of consumption after changing to low tar and nicotine cigarettes

Studies which have examined low tar and nicotine (LT/LN) cigarette smoking have failed, for the most part, to assess adequately the long-term effects of these cigarettes. Most studies have been short-term laboratory investigations of nicotine regulation. More practical strategies for changing to LT/LN cigarettes have largely been ignored. The present study examined long-term changes in smoking patterns following the gradual introduction of LT/LN cigarette smoking. Predicted increases in reported rates of consumption as well as carbon monoxide (CO) levels were not found for most smokers following changes to LT/LN cigarettes. Generally, smokers showed decreased rates of consumption, and a majority had lower CO levels at the end of treatment and during follow-up. Thus, LT/LN cigarette smoking would appear to be an alternative treatment goal for risk reduction in individuals who cannot stop smoking.     

Neonatal hippocampal lesion alters the functional maturation of the prefrontal cortex and the early cognitive development in pre-juvenile rats

Mnemonic and executive performance is encoded into activity patterns of complex neuronal networks. Lesion studies revealed that adult recognition memory critically depends on the activation of the prefrontal cortex (PFC) and hippocampus (HP). However, its developmental profile remains poorly elucidated. We previously showed the rat PFC and HP are functionally coupled in theta- and gamma-band oscillations during neonatal [postnatal day (P) 5-8] and pre-juvenile (P10-15) stages of development. Here, we assess the behavioral readout of this early prefrontal-hippocampal activation by investigating the ontogeny and the mechanisms of novelty detection and recognition memory in relationship to the functional integrity of the PFC and HP. Excitotoxic lesion of the HP at birth led to abnormal oscillatory entrainment of the PFC throughout neonatal and pre-juvenile development. Although the onset of novelty detection correlated rather with the maturation of sensory perception and motor skills than with hippocampal integrity, the pre-juvenile performance in item, spatial and temporal order recognition memory significantly decreased after HP lesion at birth. This poorer performance does result neither from abnormal developmental milestones and locomotion nor from increased anxiety. Thus, novelty recognition in rat emerges during the second postnatal week and requires functional integrity of communication within neuronal networks including the PFC and HP.     

Trust that binds: the impact of collective felt trust on organizational performance

The impact of employees' collective perceptions of being trusted by management was examined with a longitudinal study involving 88 retail stores. Drawing on the appropriateness framework (March, 1994; Weber, Kopelman, & Messick, 2004), the authors develop and test a model showing that when employees in an organization perceive they are trusted by management, increases in the presence of responsibility norms, as well as in the sales performance and customer service performance of the organization, are observed. Moreover, the relationship between perceptions of being trusted and sales performance is fully mediated by responsibility norms.     

Movement and vocal intonation together evoke social referencing in companion dogs when confronted with a suspicious stranger

Animal Cognition - Dogs have been claimed to engage in social referencing by responding in a way that corresponded with their owners' reaction in some contexts. We aimed to assess how...     

Enhancing the mental representations of space used by blind pedestrians, based on an image schemata model

The configuration of mental representation of space plays a major role in successful navigational activities. Therefore, navigational assistance for pedestrians who are blind should help them to better configure their mental representation of the environment. In this paper, we propose and exploit a computational model for the mental representation of urban areas as an aid to orientation and navigation for visually impaired pedestrians. Our model uses image schemata to capture the spatial semantics and configural elements of urban space necessary for this purpose. These image schemata are schematic structures that are continually requested by individuals in their perception, bodily movement and interaction with surrounding objects. Our proposed model also incorporates a hierarchical structure to provide different levels of detail tied to appropriate spatial perspectives at each scale. We presume that such computational model will help us to develop an appropriate structure of spatial data used to assist the target population. At the end of the paper, we illustrate the utility of our configural model by developing a typical scenario for the navigation of a blind pedestrian in an urban area.
